Description
本發明係關於消防軟管的結合扣具，尤其是關於：為了迴避消防軟管脫落所產生之危險，而具備脫落防止機構之消防軟管的結合扣具。The present invention relates to a joint fastener for a fire hose, and more particularly to a joint fastener for a fire hose having a fall prevention mechanism in order to avoid the danger of the fire hose falling off.
消防隊執行消防活動時，必須將消防軟管從消防車延伸至火點，來確實地輸送消防劑。When the fire brigade performs firefighting activities, the fire hose must be extended from the fire truck to the fire point to reliably transport the fire-fighting agent.
消防軟管及消防車之吐出口、消防軟管及放水噴嘴、以及消防軟管彼此，係由結合扣具所連結。從消防車，經過加壓之水或泡沫通過該等，被輸送至放水噴嘴，來進行以消防等為目的之放出。Fire hoses and fire truck spit outlets, fire hoses and water discharge nozzles, and fire hoses are connected to each other by a combination fastener. From the fire truck, the pressurized water or the foam passes through the water, and is sent to the water discharge nozzle for the purpose of fire prevention and the like.
日本所販賣之結合扣具，有***式、螺栓式、以及扭結式。***式之町野式結合扣具，構造簡單又輕量，裝脫操作性優良，而為大部分之消防隊所使用。The combination of fasteners sold in Japan is plug-in, bolt-on, and kinky. The plug-in type of the field-type combination buckle is simple and lightweight, and has excellent detachability and is used by most fire brigades.
第12圖至第14圖，係町野式結合扣具之構造。Fig. 12 to Fig. 14 show the structure of the combination of the town and the wild type.
結合扣具，係由承接扣具10及***扣具20所構成。The binding buckle is composed of a receiving buckle 10 and an insertion buckle 20.
***扣具20，係由***扣具本體21及壓輪22所構成。***扣具本體21之其中一方，設有以「與承接扣具10之承接扣具爪17進行卡止為目的」之環狀突部23。***扣具本體21之另一方，則設有由鋸齒狀剖面所構成之***扣具用軟管連結部24。壓輪22，係由以「使承接扣具爪17偏移為目的」之卡止解除用圓筒部22a、及以手指推壓之鍔狀操作部22b所構成。卡止解除用圓筒部22a之外徑，稍大於***扣具本體21之環狀突部23的外徑。The insertion buckle 20 is formed by inserting the buckle body 21 and the pressure roller 22. One of the insertion body bodies 21 is provided with an annular projection 23 for "the purpose of locking the fastener claws 17 of the receiving buckle 10". The other of the insertion of the clip body 21 is provided with a hose connecting portion 24 for inserting a clip which is formed by a zigzag cross section. The pressure roller 22 is composed of a locking release cylindrical portion 22a for "the purpose of shifting the receiving claws 17" and a snap-shaped operating portion 22b that is pressed by a finger. The outer diameter of the locking release cylindrical portion 22a is slightly larger than the outer diameter of the annular projection 23 inserted into the clip body 21.
承接扣具10，係由承接扣具本體11、承接扣具鎖緊輪13、爪彈簧座14、承接扣具爪17、爪彈簧15、橡膠帶16、及O形環18所構成。The buckle 10 is formed by the receiving buckle body 11, the receiving buckle locking wheel 13, the claw spring seat 14, the receiving buckle claw 17, the claw spring 15, the rubber band 16, and the O-ring 18.
承接扣具鎖緊輪13、爪彈簧座14、承接扣具爪17、爪彈簧15、橡膠帶16、及O形環18，係配置於承接扣具本體11之其中一方。承接扣具本體11之另一方，則設有由鋸齒狀剖面所構成之承接扣具用軟管連結部12。The buckle locking wheel 13, the claw spring seat 14, the receiving buckle claw 17, the claw spring 15, the rubber band 16, and the O-ring 18 are disposed on one of the receiving buckle bodies 11. The other of the fastener body 11 is provided with a hose connecting portion 12 for receiving the fastener which is formed by a zigzag cross section.
複數之承接扣具爪17，係以等間隔設於圓周方向，而具有朝向承接扣具10之前端(其中一方之開口)的斜面。此外，承接扣具爪17，可以沿著爪彈簧座14於徑方向滑動。爪彈簧15，則保持將承接扣具爪17朝中心方向彈推。The plurality of receiving clip claws 17 are provided at equal intervals in the circumferential direction, and have inclined faces facing the front end of one of the fasteners 10 (the opening of one of them). Further, the clip claws 17 are received to be slidable in the radial direction along the claw spring seats 14. The claw spring 15 keeps pushing the catching claws 17 toward the center.
將***扣具20***承接扣具10時，***扣具本體21之前端(其中一方之開口)之邊緣，抵接於承接扣具爪17之斜面，而抑制爪彈簧15之力，使承接扣具爪17後退(朝外側向移動)。因此，***扣具本體21之前端，進入到承接扣具本體11之擋止部19為止，***扣具本體21之外周面及承接扣具本體11之內周面，為O形環18所密封。此時，***扣具本體21之環狀突部23，因為越過了承接扣具爪17的位置，因此承接扣具爪17，被爪彈簧15之力朝中心方向彈推，而回到原來之位置，即完成結合。When the insertion clip 20 is inserted into the receiving clip 10, the edge of the front end (the opening of one of the sides) of the clip body 21 is inserted into the bevel of the receiving clip claw 17, and the force of the claw spring 15 is suppressed to make the buckle With the claw 17 retreating (moving toward the outside). Therefore, the front end of the insertion body 21 is inserted into the stopper portion 19 of the fastener body 11, and the outer circumferential surface of the fastener body 21 and the inner circumferential surface of the fastener body 11 are received, and the O-ring 18 is sealed. . At this time, the annular projection 23 of the insertion body 21 is inserted over the position at which the fastener claw 17 is received, so that the fastener claw 17 is received, and is pushed by the force of the claw spring 15 toward the center, and returns to the original state. Position, that is, complete the combination.
被結合之扣具之解除，使壓輪22朝承接扣具10之方向，亦即，使其朝***扣具本體21之環狀突部23之方向移動。藉由移動壓輪22，卡止解除用圓筒部22a抵接於承接扣具爪17之斜面，而一邊使承接扣具爪17偏移一邊進入至***扣具20之環狀突部23。因此，承接扣具爪17及環狀突部23的勾結被解除，而解除結合。The release of the engaged buckle causes the pressure roller 22 to move in the direction in which the buckle 10 is received, that is, in the direction in which the annular projection 23 of the fastener body 21 is inserted. By moving the pressure roller 22, the locking release cylindrical portion 22a abuts against the inclined surface of the receiving buckle claw 17, and enters the annular projection 23 of the insertion buckle 20 while the receiving buckle claw 17 is displaced. Therefore, the hooking of the hooking claws 17 and the annular projections 23 is released, and the coupling is released.
如此，町野式結合扣具，可以簡單地進行結合及解除。另一方面，具有良好操作性之缺點，因為沒有固定「用以解除扣具之結合狀態之壓輪22」的機構，當受到衝擊及軟管移動時之拉扯等而使壓輪22朝解除方向移動，可能發生承接扣具爪17脫開而使軟管連結部24脫離之情形。實際上，在火災現場的消防活動中，有時放水噴嘴及軟管之結合扣具的脫離；或有時因軟管延長時結合扣具受到衝擊、或在樓梯處延長軟管時結合扣具之壓輪22被樓梯卡住，而導致軟管連結部24脫離。此時，送水受到中斷，而妨礙到消防活動。並且，結合部脫離之軟管的水流不受控制，也可能對附近的人造成危害。In this way, the town and the field combined with the buckle can be easily combined and released. On the other hand, there is a disadvantage of good operability, because the mechanism for "the pressure roller 22 for releasing the combined state of the buckle" is not fixed, and the pressure roller 22 is pulled toward the release direction when subjected to impact and hose movement. When moving, it may happen that the hooking claws 17 are disengaged and the hose connecting portion 24 is detached. In fact, in the fire fighting activities at the fire site, sometimes the combination of the water discharge nozzle and the hose is detached; or sometimes the buckle is impacted when the hose is extended, or the buckle is extended when the hose is extended at the stairs. The pressure roller 22 is caught by the stairs, causing the hose coupling portion 24 to be disengaged. At this time, the water supply was interrupted and the fire fighting activities were hindered. Moreover, the water flow of the hose from which the joint is detached is not controlled, and may also be harmful to people in the vicinity.
此外，訓練及消防活動中，也可能發生在未洩除軟管之壓力的情形下，解除結合扣具之人為過失。In addition, in training and fire fighting activities, it may happen that the pressure of the hose is not released, and the person who removes the buckle is faulty.
換言之，經水或壓縮空氣加壓之消防軟管的結合扣具，因為外部原因或人的操作失誤而被不小心解除的話，不但對消防活動造成妨礙，也可能對操作者本人及周圍的人造成危害。因此，防止發生上述危險係消防的課題。In other words, if the combination of the fire hose pressurized with water or compressed air is accidentally removed due to external reasons or human error, it may not only hinder the fire fighting activities, but may also affect the operator himself and the people around him. Causes harm. Therefore, it is a problem to prevent the above-mentioned dangerous firefighting.
近年來，配載壓縮空氣泡沫消防系統(CAFS：Compressed Air Foam System)之消防車逐漸增加。CAFS車，可以簡單地切換水及泡沫之放射，比傳統之泵車更能對應各種火災，也能更有效率地進行消防。相反的，CAFS車，因為使用壓縮空氣泡，結合扣具不小心被解除時，會噴出具有大能量的壓縮空氣泡沫。壓縮空氣泡沫，相較於水，可能對周圍造成更大的危害。所以，防止消防軟管的結合扣具被不小心解除係重要的事務。In recent years, fire trucks equipped with the Compressed Air Foam System (CAFS) have gradually increased. The CAFS car can easily switch between water and foam radiation, which is more suitable for various fires than traditional pump trucks, and can also be fired more efficiently. Conversely, CAFS vehicles, when compressed air bubbles are used, can be ejected with a large amount of compressed air foam when the buckle is accidentally released. Compressed air foam can cause more damage to the surroundings than water. Therefore, it is important to prevent the combination of the fire hose from being accidentally released.
專利文獻1之方法，係防止壓輪22被障礙物勾住而不小心解除結合之方法。亦即，藉由於***扣具20及承接扣具10之外周，裝設具有外徑大於壓輪22之外徑的蓋零件，來使壓輪22不容易接觸到地面及障礙物。The method of Patent Document 1 is a method of preventing the pressure roller 22 from being caught by an obstacle and unintentionally releasing the bonding. That is, by inserting the clip 20 and the outer circumference of the receiving buckle 10, a cover member having an outer diameter larger than the outer diameter of the pressure roller 22 is provided, so that the pressure roller 22 does not easily come into contact with the ground and obstacles.
此外，專利文獻2及專利文獻3之方法時，係於***扣具20之壓輪22與承接扣具10之鎖緊輪之間，置入限制壓輪22之移動的鎖定零件，來防止結合扣具不小心被解除的方法。Further, in the methods of Patent Document 2 and Patent Document 3, between the pressure roller 22 inserted into the buckle 20 and the lock wheel of the buckle 10, a locking member that restricts the movement of the pressure roller 22 is placed to prevent the joint. The method by which the buckle is accidentally lifted.

然而，依據專利文獻1的話，不但結合扣具之重量及體積增加，操作性受損，成本也會增加。此外，無法防止人為失誤所導致之結合的錯誤解除。However, according to Patent Document 1, not only the weight and volume of the fastener are increased, the operability is impaired, and the cost is also increased. In addition, it is impossible to prevent the error of the combination caused by human error.
此外，依據專利文獻2及專利文獻3的話，雖然可以防止軟管移動中壓輪勾到障礙物而使結合扣具脫離，然而，並無法防止錯誤操作所造成的錯誤脫離。此外，裝設鎖定零件的作法，在分秒必爭的消防活動中，則顯得有些麻煩，而導致軟管操作性的受損。並且，也可能發生忘記裝設鎖定零件之人為失誤。Further, according to Patent Document 2 and Patent Document 3, it is possible to prevent the pressure roller from hooking to the obstacle and the engagement buckle to be detached while the hose is moving. However, it is not possible to prevent erroneous detachment due to erroneous operation. In addition, the installation of the locking parts is somewhat troublesome in the fire fighting activities that are necessary for every second, resulting in damage to the hose's operability. Also, human error that forgets to install the locked part may occur.
本發明要解決之課題，係提供可解決上述傳統技術問題，可防止拉動消防軟管時障礙物所導致之結合扣具的解除及軟管加壓時因為人的錯誤操作所導致之結合扣具的解除，而且，無需追加附加零件之程序，在無損傳統優良操作性之情形下，可以更有效率且安全地執行消防活動之消防軟管用結合扣具。The problem to be solved by the present invention is to provide a combination fastener capable of solving the above-mentioned conventional technical problems, which can prevent the release of the binding buckle caused by the obstacle when the fire hose is pulled and the wrong operation of the human when the hose is pressurized. The release of the fire hose for the fire protection can be performed more efficiently and safely without the need to add additional parts.
如以上所示，依據本發明之消防軟管的結合扣具，可以一邊維持傳統結合扣具之優良操作性，一邊防止軟管加壓時之錯誤操作所導致之結合扣具的脫離、及軟管移動中障礙物所導致之結合扣具的脫離。因此，可以迴避結合扣具之不小心脫離所造成之軟管亂甩等的危險，而可更安全且迅速地執行消防活動。As shown above, the combination buckle of the fire hose according to the present invention can prevent the detachment of the joint buckle and the softness caused by the erroneous operation of the hose when the hose is maintained while maintaining the excellent operability of the conventional joint fastener. The detachment of the combined buckle caused by the obstacle in the movement of the tube. Therefore, it is possible to avoid the danger of inadvertent disengagement of the hose caused by the inadvertent disengagement of the buckle, and to perform the fire fighting activity more safely and quickly.
本發明之第1實施方式之消防軟管的結合扣具，是如以下所構成之消防軟管的結合扣具：係由***扣具20及承接扣具10所構成，前述***扣具20，係具有：於其中一方設有環狀突部23，於另一方設有***扣具用軟管連結部24，並於前述環狀突部23及前述***扣具用軟管連結部24之間設有滑動圓筒部25之***扣具本體21；及可以前述滑動圓筒部25進行滑動之壓輪22；且，前述承接扣具10，係具有：「於其中一方設有承接扣具爪17，於另一方設有承接扣具用軟管連結部12」之承接扣具本體11；及「將前述承接扣具爪17朝前述承接扣具本體11之中心軸線X1之方向彈推」的爪彈簧15；且藉由從前述承接扣具本體11之其中一方***，直到前述環狀突部23超越前述承接扣具爪17之位置為止，來使前述***扣具20及前述承接扣具10結合，使前述壓輪22沿著前述滑動圓筒部25滑動而***前述承接扣具10，並抵接於前述承接扣具爪17之卡止解除用斜面17a，藉由前述壓輪22推壓前述卡止解除用斜面17a使前述承接扣具爪17朝外側偏移，而解除前述承接扣具爪17及前述環狀突部23之卡止，藉以解除前述***扣具20及前述承接扣具10之結合，其中於環狀突部23之***扣具用軟管連結部側端面23a，設有形成有斜面23b之卡止鎖定用溝23c，於承接扣具爪17，設有與斜面23b抵接的突起17b。依據本實施方式，軟管被加壓的話，***扣具20及承接扣具10朝脫離之方向移動，由卡止鎖定用溝23c所形成之斜面23b及加工形成於承接扣具爪17之突起17b所形成的斜面23b相互嚙合。結果，因為結合狀態被鎖定，在軟管使用中，可以防止因錯誤操作及外部之勾扯等而不小心脫離。另一方面，軟管未被加壓之未使用時，因為結合狀態未被鎖定而容易執行脫離操作。The joint fastener for a fire hose according to the first embodiment of the present invention is a joint fastener for a fire hose which is constituted by the insertion buckle 20 and the socket fastener 10, and the insertion buckle 20 is The one of the annular protrusions 23 is provided in one of the annular protrusions 23 and the insertion hose connection portion 24 is provided between the annular projection 23 and the insertion hose connection portion 24 The insertion buckle body 21 is provided with a sliding cylindrical portion 25; and the pressure roller 22 is slidable by the sliding cylindrical portion 25; and the receiving buckle 10 has: "The one of the receiving buckles 10 is provided with a receiving claw 17.

如第2圖所示，***扣具20及承接扣具10，係從承接扣具本體11之其中一方開口將環狀突部23***至超過承接扣具爪17之位置。亦即，***扣具本體21之前端環狀突部23，抵接於承接扣具爪17之卡止解除用斜面17a，抑制爪彈簧15之力，而使承接扣具爪17後退。因此，環狀突部23之前端，進入至承接扣具本體11之擋止部19，而為O形環18所密封。此時，***扣具本體21之環狀突部23，因為超過承接扣具爪17，因此承接扣具爪17藉由爪彈簧15之力而朝中心軸線X1之方向前進，並回到原來的位置。因此，***扣具本體21之環狀突部23卡止於承接扣具爪17而完成結合。As shown in Fig. 2, the insertion of the clip 20 and the receiving of the clip 10 are such that the annular projection 23 is inserted from the one of the receiving clip main bodies 11 beyond the receiving clip claw 17. In other words, the front end annular projection 23 of the clip body 21 is inserted into the locking release slope 17a of the receiving clip claw 17, and the force of the claw spring 15 is suppressed, and the receiving clip claw 17 is retracted. Therefore, the front end of the annular projection 23 enters the stopper portion 19 that receives the fastener body 11, and is sealed by the O-ring 18. At this time, since the annular projection 23 of the clip body 21 is inserted beyond the receiving clip claw 17, the receiving clip claw 17 advances in the direction of the central axis X1 by the force of the claw spring 15, and returns to the original position. Therefore, the annular projection 23 inserted into the clip body 21 is locked to the receiving clip claw 17 to complete the bonding.
解除***扣具20及承接扣具10之結合時，使壓輪22沿著滑動圓筒部25滑動而***承接扣具10，並抵接於承接扣具爪17之卡止解除用斜面17a，利用壓輪22推壓卡止解除用斜面17a，而使承接扣具爪17往外側偏移，進而解除承接扣具爪17及環狀突部23之卡止。When the coupling of the insertion buckle 20 and the receiving buckle 10 is released, the pressure roller 22 is slid along the sliding cylindrical portion 25 and inserted into the receiving buckle 10, and abuts against the locking releasing slope 17a of the receiving claw claw 17, When the lock releasing blade inclined surface 17a is pressed by the pressure roller 22, the receiving buckle claws 17 are displaced outward, and the engagement of the receiving buckle claws 17 and the annular projections 23 is released.
本實施例之消防軟管的結合扣具，於環狀突部23之***扣具用軟管連結部側端面23a，設有形成有斜面23b之卡止鎖定用溝23c，於承接扣具爪17，則設有與斜面23b抵接之突起17b。In the joint fastener of the fire hose of the present embodiment, the hook end portion 23a of the hook portion is inserted into the end portion 23a of the hook portion 23, and the locking groove 23c is formed with the inclined surface 23b. 17, a projection 17b that abuts against the inclined surface 23b is provided.
卡止鎖定用溝23c之斜面23b相對於***扣具20之中心軸線X2的角度α，係0°<α<90°之範圍，且設為45°。此外，與該斜面23b抵接之突起17b的斜面，也是與卡止鎖定用溝23c之斜面23b之角度α相同的角度。The angle α of the slope 23b of the locking groove 23c with respect to the central axis X2 of the insertion buckle 20 is in the range of 0° < α < 90° and is set to 45°. Further, the inclined surface of the projection 17b that abuts against the inclined surface 23b is also at the same angle as the angle ? of the inclined surface 23b of the locking locking groove 23c.
卡止解除用斜面17a相對於***扣具本體21之中心軸線X2之角度為β時，β<α。When the angle of the locking release slope 17a with respect to the central axis X2 of the insertion of the fastener body 21 is β, β < α.
3個承接扣具爪17，係以等間隔設於承接扣具10之圓周方向。承接扣具爪17，具有朝向承接扣具10之入口的卡止解除用斜面17a，此外，可以沿著爪彈簧座14而在半徑方向滑動。爪彈簧15，持續地對承接扣具爪17施加使其朝中心軸線X2方向移動之力。The three receiving clip claws 17 are provided at equal intervals in the circumferential direction of the receiving clip 10. The buckle claw 17 is received, and has a locking release slope 17a that faces the inlet of the buckle 10, and is slidable in the radial direction along the claw spring holder 14. The claw spring 15 continuously applies a force to the receiving buckle claw 17 to move in the direction of the central axis X2.
軟管被加壓的話，***扣具20及承接扣具10朝脫離方向移動。並且，由卡止鎖定用溝23c所形成之斜面23b及對承接扣具爪17加工而形成之突起17b的斜面，相互嚙合，而鎖定成結合狀態。When the hose is pressurized, the insertion buckle 20 and the receiving buckle 10 are moved in the disengaging direction. Further, the inclined surface 23b formed by the locking groove 23c and the inclined surface of the projection 17b formed by processing the fastener claw 17 are engaged with each other to be locked in a coupled state.
軟管未被施加壓力之狀態時，與傳統相同，以手指將壓輪22之鍔狀操作部22b朝承接扣具10之方向，亦即，朝***扣具本體21之環狀突部23的方向推壓。如此一來，壓輪22之卡止解除用圓筒部22a，抵接於對承接扣具爪17加工而形成之突起17b的斜面，並一邊使承接扣具爪17偏移一邊前進至***扣具20之環狀突部23。因此，承接扣具爪17及環狀突部23之勾結被解除，結合之扣具即被解除。When the hose is not in a state where pressure is applied, the handle portion 22b of the pressure roller 22 is directed toward the direction of the fastener 10 by the finger, that is, toward the annular projection 23 of the fastener body 21, as in the conventional case. Push in the direction. In this manner, the locking release cylindrical portion 22a of the pressure roller 22 abuts against the inclined surface of the projection 17b formed by processing the fastener claw 17, and advances to the insertion buckle while shifting the receiving buckle claw 17 There is an annular protrusion 23 of 20. Therefore, the hooking of the hooking claws 17 and the annular projections 23 is released, and the combined fasteners are released.
軟管之非加壓時之結合扣具的脫離對策，於壓輪22之卡止解除用圓筒部22a之內周面的兩端，進行微細溝之壓輪側止滑溝22c的加工。於***扣具本體21之滑動圓筒部25的外周面，則進行微細溝之本體側止滑溝25a的加工。In the non-pressurization of the hose, the detachment of the nip is performed on the both ends of the inner circumferential surface of the cylinder portion 22a for releasing the pressure of the pressure roller 22, and the pressure wheel side sipe 22c of the fine groove is processed. When the outer peripheral surface of the sliding cylindrical portion 25 of the clip body 21 is inserted, the main-side slip groove 25a of the fine groove is processed.
如第5圖所示，壓輪22之鍔狀操作部22b為障礙物所勾扯，使壓輪22成為一側受力之狀態的話，卡止解除用圓筒部22a之前端的其中一方浮起，另一方則突向扣具本體21的外周。此外，卡止解除用圓筒部22a之後部也會發生相同的現象。所以，形成壓輪側止滑溝22c及本體側止滑溝25a的話，可以使卡止解除用圓筒部22a之內周及***扣具本體21互相卡止。施加於其中一方之障礙物的力，具有止滑效果。因此，可以防止結合扣具因為障礙物而不小心脫離。As shown in Fig. 5, when the meandering operation portion 22b of the pressure roller 22 is hooked by an obstacle and the pressure roller 22 is in a state of being biased by one side, one of the front ends of the locking release cylindrical portion 22a is floated. The other side protrudes toward the outer circumference of the body 21 of the buckle. Further, the same phenomenon occurs in the rear portion of the locking release cylindrical portion 22a. Therefore, when the pressure wheel side slip groove 22c and the main body side slip groove 25a are formed, the inner circumference of the unlocking cylindrical portion 22a and the insertion buckle body 21 can be locked to each other. The force applied to one of the obstacles has a slip-resisting effect. Therefore, it is possible to prevent the bonding clip from being inadvertently detached due to an obstacle.
第6圖，係本發明之其他實施例之消防軟管的結合扣具。Figure 6 is a combination of fire hoses of other embodiments of the present invention.
第6圖，係本實施例之消防軟管的結合扣具用***扣具的半剖面圖，係拆除壓輪之狀態。壓輪22及承接扣具10，因為與上述實施例相同，故省略其說明。此外，與傳統例相同機能之零件，賦予相同符號並省略部分說明。Fig. 6 is a half sectional view showing the insertion buckle of the fire hose of the present embodiment, which is a state in which the pressure roller is removed. Since the pressure roller 22 and the receiving buckle 10 are the same as those of the above embodiment, the description thereof will be omitted. In addition, parts having the same functions as those of the conventional example are given the same reference numerals and a part of the description is omitted.
本實施例中，形成有複數條橫跨本體側止滑溝25a之銷槽25b，係以銷槽25b之兩端超過本體側止滑溝25a之寬度的方式來附設。In the present embodiment, a plurality of pin grooves 25b which are formed across the main body side slip groove 25a are formed so that both ends of the pin groove 25b exceed the width of the body side slip groove 25a.
要除去附著於銷槽25b之砂及粉塵時，以刷子或布等抵靠於溝並沿著外周進行移動。藉此，可從本體側止滑溝25a將砂及粉塵推出銷槽25b，而容易除去砂及粉塵。When sand and dust adhering to the pin groove 25b are removed, the brush or cloth or the like abuts against the groove and moves along the outer circumference. Thereby, sand and dust can be pushed out of the pin groove 25b from the main body side stop groove 25a, and sand and dust can be easily removed.
第7圖，係施加於軟管壓力(放水壓力)及軟管之軸方向之拉伸力的關係。該拉伸力係作用於使結合扣具脫離之方向。放水壓力，一般為0.3Mpa以上。對應於該壓力之公稱65mm及50mm之軟管的拉伸力分別為720N及1100N以上。藉由令「由卡止鎖定用溝23c所形成的斜面23b」及「對承接扣具爪17加工而形成之突起17b的斜面」相互嚙合，利用該軟管加壓時之拉伸力，可鎖定扣具彼此之結合狀態。Fig. 7 is a relationship between the tensile force applied to the hose pressure (discharge pressure) and the axial direction of the hose. This tensile force acts on the direction in which the bonding clip is disengaged. The discharge pressure is generally 0.3Mpa or more. The hoses of the nominal 65 mm and 50 mm hoses corresponding to the pressure have a tensile force of 720 N and 1100 N or more, respectively. By engaging the "bevel surface 23b formed by the locking locking groove 23c" and the "slanting surface of the projection 17b formed by processing the fastening claw 17", the tensile force at the time of pressing the hose can be used. The locking clips are coupled to each other.
第8圖，係結合扣具之卡止鎖定及解除相關之力關係示意圖。F1，係軟管之加壓所發生的拉伸力。F2，係F1之分力所發生的力。該力使爪彈簧朝中心軸X2之方向移動，亦即，以不會解除卡止之方式作用。F4，係從壓輪22所承受到之力。此外，F3，係F4之分力，以解除卡止之方式作用。F3及F2相等時，保持均衡。若α為卡止鎖定用溝23c之斜面23b相對於***扣具20之中心軸線X2的角度的話，則斜面23b之角度α，可以加工成0°~90°之任意角度。此外，若β為卡止解除用斜面17a相對於***扣具本體21之中心軸線X2的角度的話，則卡止解除用斜面17a之角度β為一定。此處，爪彈簧在F2之力下朝半徑方向移動L2之距離，同時，克服F1之力，環狀突部23朝軸方向移動L1之距離。此時，做功量(workload)為F1×L1=F2×L2。此外，L1/L2=tan(90-α)，各力及角度之關係如下所示。Fig. 8 is a schematic diagram showing the relationship between the locking and the disengagement of the buckle. F1 is the tensile force that occurs when the hose is pressurized. F2 is the force generated by the force of F1. This force moves the claw spring in the direction of the central axis X2, that is, in a manner that does not release the locking. F 4 is the force that is received from the pressure roller 22 . In addition, F 3 , the component of F 4 , acts to release the lock. When F 3 and F2 are equal, they are balanced. If α is the angle of the inclined surface 23b of the locking locking groove 23c with respect to the central axis X2 of the insertion buckle 20, the angle α of the inclined surface 23b can be processed to any angle of 0° to 90°. In addition, when β is the angle of the locking release slope 17a with respect to the central axis X2 of the insertion of the fastener body 21, the angle β of the locking release slope 17a is constant. Here, the claw spring moves by a distance of L2 in the radial direction under the force of F2, and at the same time, the distance of the annular projection 23 is moved by L1 in the axial direction against the force of F1. At this time, the work load is F1 × L1 = F2 × L2. Further, L1/L2=tan(90-α), and the relationship between each force and angle is as follows.
F2/F1=tan(90-α)…式(1)F2/F1=tan(90-α)...(1)
F4/F3=tanβ…式(2)F 4 /F 3 =tanβ...(2)
同樣的，F3=F2 tanβ=a(constant)，因此Similarly, F 3 =F2 tanβ=a(constant), so
F4=aF1tan(90-α)…式(3)F 4 = aF1tan(90-α)...(3)
如式(3)所示，藉由改變斜面23b之角度α，可改變一定壓力F1之解除力的大小。傳統之結合扣具，因為無鎖定用之溝，α為90°。因此，tan(90-α)=0，F4=0。亦即，傳統構造中，即使在承受到壓力之狀態下，只要有可克服爪彈簧15之力及卡止面之摩擦抵抗力的力，就可解除結合。As shown in the formula (3), by changing the angle α of the inclined surface 23b, the magnitude of the releasing force of the constant pressure F1 can be changed. The traditional combination of buckles, because there is no groove for locking, α is 90°. Therefore, tan (90-α) = 0, F 4 = 0. That is, in the conventional structure, even in a state of being subjected to pressure, the coupling can be released as long as there is a force that can overcome the force of the claw spring 15 and the frictional resistance of the locking surface.
另一方面，α為0°的話，tan(90-α)為無窮大，與軟管之內壓無關，解除卡止所需要之力F4為無窮大。如此一來，適當設定斜面23b之角度α的話，就可決定對應其之解除力。將最小放射壓之結合扣具的解除力(包含爪彈簧力及摩擦力)設定成大於人之手指的力，即使發生錯誤操作，也可避免結合扣具被不小心解除。此外，在加壓狀態下移動軟管時，即使例如為障礙物所勾扯，扣具之結合也不會很簡單就脫離。On the other hand, when α is 0°, tan(90-α) is infinite, and the force F 4 required to release the lock is infinite regardless of the internal pressure of the hose. In this way, if the angle α of the inclined surface 23b is appropriately set, the releasing force corresponding thereto can be determined. The release force of the combined buckle of the minimum radiation pressure (including the claw spring force and the friction force) is set to be greater than the force of the human finger, and even if an erroneous operation occurs, the binding buckle can be prevented from being accidentally released. Further, when the hose is moved under pressure, even if the obstacle is hooked, for example, the combination of the buckles does not easily come off.
此外，只採用前述對策時，在軟管未加壓之狀態下，因為無法利用軟管之壓力來鎖定結合扣具，移動中，無法防止障礙物所導致之結合扣具的脫離。因此，於壓輪22之卡止解除用圓筒部22a之內周面的兩端，加工形成微細溝之壓輪側止滑溝22c。於***扣具本體21之滑動圓筒部25的外周面，則形成微細溝之本體側止滑溝25a。Further, when only the above countermeasures are employed, in the state where the hose is not pressurized, since the engagement buckle cannot be locked by the pressure of the hose, it is impossible to prevent the engagement of the engagement buckle due to the obstacle during the movement. Therefore, the pressure wheel side slip groove 22c of the fine groove is formed at both ends of the inner circumferential surface of the lock releasing cylindrical portion 22a of the pressure roller 22. When the outer peripheral surface of the sliding cylindrical portion 25 of the clip body 21 is inserted, the main body side slip groove 25a of the fine groove is formed.
人為解除結合扣具時，以兩手之手指均衡地推壓壓輪22之鍔狀操作部22b。相對於此，壓輪22之鍔狀操作部22b被障礙物勾扯時，鍔狀操作部22b之其中一方承受到力。因為壓輪22之卡止解除用圓筒部22a的內周及***扣具本體21的外周之間，有少許的間隙，倘若形成其中一方受力之狀態的話，如第5圖所示，卡止解除用圓筒部22a之前端的其中一方浮起，而另一方則突向***扣具本體21的外周。此外，卡止解除用圓筒部22a之後部也會發生相同的現象。所以，藉由形成本體側止滑溝25a，卡止解除用圓筒部22a之端面可以卡止，藉由於卡止解除用圓筒部22a之內周面的兩端形成壓輪側止滑溝22c，互相卡止更為確實，施加於其中一方之障礙物的力，具有止滑效果。因此，可以防止障礙物導致之結合扣具的不小心脫離。When the engagement buckle is manually released, the jaw-shaped operation portion 22b of the pressure roller 22 is uniformly pressed by the fingers of both hands. On the other hand, when the meandering operation portion 22b of the pressure roller 22 is hooked by the obstacle, one of the jaw-shaped operation portions 22b receives a force. There is a slight gap between the inner circumference of the locking release cylindrical portion 22a of the pressure roller 22 and the outer circumference of the insertion buckle body 21, and if one of the forces is formed, as shown in Fig. 5, the card is as shown in Fig. 5 One of the front ends of the release cylindrical portion 22a is floated, and the other is protruded toward the outer periphery of the insertion body 21. Further, the same phenomenon occurs in the rear portion of the locking release cylindrical portion 22a. Therefore, the end surface of the locking release cylindrical portion 22a can be locked by the main body side sliding groove 25a, and the both ends of the inner circumferential surface of the locking release cylindrical portion 22a form the pressure wheel side sliding groove. 22c, the mutual locking is more reliable, and the force applied to one of the obstacles has a slip-resisting effect. Therefore, it is possible to prevent the inadvertent detachment of the engaging buckle caused by the obstacle.
第9圖，係針對傳統結合扣具及本實施例之結合扣具之解除力的實測值。Fig. 9 is a measured value of the releasing force of the conventional bonding clip and the combined buckle of the embodiment.
為了證明本發明之有用性，試作「具有45°之卡止鎖定用溝23c之斜面23b之角度α」的結合扣具，並改變軟管壓來進行解除力之測定。此外，為了進行比較，也進行傳統結合扣具之解除力的測定。此處之解除力，係指在***扣具20及承接扣具10之結合狀態下，以解除結合扣具之卡止為目的，而對壓輪22之鍔狀操作部22b所施加之力的最大值。此處所示之必要解除力的測定值，係爪彈簧15之力、摩擦力、及斜面嚙合所形成之鎖定力的合計值。In order to prove the usefulness of the present invention, a joint fastener having "the angle ? of the slope 23b of the locking lock groove 23c of 45 degrees" was tried, and the hose pressure was changed to measure the releasing force. In addition, for comparison, the determination of the releasing force of the conventional bonding clip is also performed. The releasing force here refers to the force applied to the jaw-shaped operating portion 22b of the pressure roller 22 for the purpose of releasing the locking of the engaging buckle in the combined state of the insertion of the buckle 20 and the receiving of the buckle 10. Maximum value. The measured value of the required releasing force shown here is the total value of the force of the claw spring 15, the frictional force, and the locking force formed by the meshing of the inclined surface.
如第9圖所示，在軟管未承受到壓力之狀態下，傳統品及本實施例之解除力為同等。另一方面，在軟管之加壓狀態下，隨著其壓力的增大，扣具之結合解除所必要之力增加。通常之最低使用壓力0.3MPa時，本實施例之解除力為傳統品之約6倍。As shown in Fig. 9, in the state where the hose is not subjected to the pressure, the releasing force of the conventional product and the present embodiment is the same. On the other hand, in the pressurized state of the hose, as the pressure increases, the force necessary for the release of the buckle is increased. When the minimum use pressure is 0.3 MPa, the release force of this embodiment is about 6 times that of the conventional product.
第10圖，係人為解除結合扣具之卡止時之最大指力的測定值。Fig. 10 is a measurement result of the maximum finger force when the engagement of the buckle is artificially released.
因為***扣具20及承接扣具10之構造不同，解除其時之操作者及結合扣具的相對位置，亦即，隨著站立在***扣具20側、或站立在承接扣具10側，手指之握持容易性改變，同時，出力之方向也會改變。測定，係針對相同被驗者，以二個位置來進行測定。此外，測定對象，分成一般人及消防人員，針對各群組來進行測定。依據其結果的話，以解除結合扣具之一般人之指力的最小值、最大值、及平均值，分別為140N、550N、及308N。此外，消防隊員之指力的最小值、最大值、及平均值，分別為149N、680N、及398N。Because the structure of the insertion buckle 20 and the receiving buckle 10 are different, the relative positions of the operator and the binding buckle are released, that is, as they stand on the side of the insertion buckle 20 or stand on the side of the receiving buckle 10, The grip of the finger changes easily, and the direction of the output changes. The measurement was performed at two positions for the same subject. In addition, the measurement target is divided into an average person and a firefighter, and measurement is performed for each group. According to the result, the minimum value, the maximum value, and the average value of the finger force of the general person who releases the bonding buckle are 140N, 550N, and 308N, respectively. In addition, the minimum, maximum, and average values of the firefighters' finger forces are 149N, 680N, and 398N, respectively.
由其結果，使用傳統結合扣具時，即使在0.7MPa之軟管壓力下，也可以人為解除結合扣具之結合。相對於此，使用本發明之結合扣具時，以人之指力可解除結合扣具之極限壓力為約0.11MPa。因為消防活動時之通常的最低使用壓力為0.3MPa，利用本實施例的話，可以防止錯誤操作下之結合扣具的脫離。As a result, when the conventional joint fastener is used, the combination of the joint fasteners can be artificially released even under a hose pressure of 0.7 MPa. On the other hand, when the bonding clip of the present invention is used, the limit pressure of the bonding buckle can be released by human finger force to be about 0.11 MPa. Since the usual minimum use pressure at the time of fire fighting is 0.3 MPa, with the present embodiment, the detachment of the joint fastener under erroneous operation can be prevented.
第11圖，係使傳統品及本實施例之結合扣具之壓輪為段差所勾扯，來調查扣具之結合是否被解除的結果。此外，在軟管未加壓之狀態下，也針對壓輪22勾扯到段差時之扣具的狀態進行調查。使用實驗新品之結合扣具，分別實施10次。同樣之拉伸力，相對於傳統品之結合以100%機率被解除，本實施例之解除機率為0%。本實施例時，在勾扯到段差等之障礙物時，證實可以防止不小心脫離。In the eleventh figure, the pressure wheel of the conventional product and the combined buckle of the present embodiment is hooked to the step to investigate whether the combination of the buckle is released. Further, in a state where the hose is not pressurized, the state of the buckle when the pressure roller 22 is hooked to the step is also investigated. The combination of the new experimental products was used for 10 times. Similarly, the tensile force is released at a 100% probability with respect to the combination of the conventional products, and the release rate of this embodiment is 0%. In the present embodiment, when an obstacle such as a step is hooked, it is confirmed that careless separation can be prevented.
所以，本發明之有用性獲得證實。Therefore, the usefulness of the present invention is confirmed.
