Description
本發明係關於一種設為可選擇地實施將液體散布至遠方之直線噴射與廣角地進行散布之廣角噴射之液體散布噴嘴，更詳細而言，本發明係關於一種可一面維持上述直線噴射與廣角噴射之功能一面亦變更噴射方向之液體散布噴嘴。 The present invention relates to a liquid spray nozzle configured to selectively perform a linear spray for spreading a liquid to a distance and a wide-angle spray for spreading at a wide angle. More specifically, the present invention relates to a liquid spray nozzle capable of maintaining the above-mentioned linear spray and wide-angle while maintaining a wide-angle spray. The spraying function also changes the spraying direction of the liquid spray nozzle.
於進行藥劑之散布或灑水之散布裝置之液體散布噴嘴中，存在如下述專利文獻1、2所示者。 There are liquid spray nozzles for spraying a medicine or spraying a spraying device, as shown in Patent Documents 1 and 2 below.
該專利文獻1所揭示之液體噴霧用噴嘴係可切換地實施將液體散布至遠方之直線噴射與廣角地進行散布之廣角噴射者。 The liquid spray nozzle disclosed in Patent Document 1 is a wide-angle sprayer that can perform linear spraying for spreading liquid to a distance and wide-angle spraying for wide-angle spraying.
又，專利文獻2所揭示之液體散布噴嘴係於噴嘴串聯配置地配備第1噴射口與第2噴射口，且於第1噴射口與第2噴射口間設置吸入外氣之吸氣孔，從而不僅具備切換地實施將液體散布至遠方之直線噴射與廣角地進行散布之廣角噴射之功能，而且亦具備將氣體吸入混合後噴射之功能。 In addition, the liquid dispersion nozzle disclosed in Patent Document 2 is provided with a first injection port and a second injection port in series with the nozzles, and an air suction hole is provided between the first injection port and the second injection port, so that It not only has the function of switching between linear spray that spreads the liquid to a distant place and wide-angle spray that spreads at a wide angle, but also has the function of sucking and mixing the gas and spraying.

[專利文獻1]日本專利特開平1-228564號公報 [Patent Document 1] Japanese Patent Laid-Open No. 1-228564
[專利文獻2]日本專利特開2008-110318號公報 [Patent Document 2] Japanese Patent Laid-Open No. 2008-110318
上述專利文獻1之液體噴霧用噴嘴係於操作桿之彎曲之前端固定地設置噴嘴部，從而無法改變噴射口之朝向(散布方向)。專利文獻2之液體散布噴嘴亦為相同情況。 The nozzle for liquid spraying of the above-mentioned Patent Document 1 is provided with a nozzle portion fixed at the curved front end of the operating lever, so that the direction (spreading direction) of the ejection port cannot be changed. The same is true of the liquid dispersion nozzle of Patent Document 2.
若可一面具有直線噴射與廣角噴射之功能，一面變更噴射口之朝向，則可液體散布噴嘴之用途擴大，從而該噴嘴之使用便利性亦變佳。 If the functions of linear spraying and wide-angle spraying can be changed while the orientation of the spray port is changed, the use of the liquid-dispersing nozzle can be expanded, and the usability of the nozzle can be improved.
然而，具有直線噴射與廣角噴射之兩功能之噴嘴係成為以閥切換使噴霧用之液體通過之通路孔之連接狀態，從而切換直線噴射與廣角噴射之結構，以此種結構之噴嘴變更噴射口之朝向必須進行設計。 However, a nozzle having two functions of linear spraying and wide-angle spraying is to switch the connection state of the passage hole through which the liquid for spraying is passed by a valve, so that the structure of the linear spraying and wide-angle spraying is switched. The orientation must be designed.
即，若設為使具有噴射口之噴嘴之頭部包含上述閥，且該頭部以連接角可變之方式連接於操作桿(噴管)之結構，則用以開閉閥之機構變得複雜，從而無法避免頭部大型化。 That is, if the head of a nozzle having a spray port includes the above valve, and the head is connected to the operating lever (nozzle) with a variable connection angle, the mechanism for opening and closing the valve becomes complicated , So that the head size cannot be avoided.
又，若採用已知之球接頭作為管接頭，則因噴射口之朝向而無法避免直線噴射用通路孔與廣角噴射用通路孔連通，從而無法維持直線噴射與廣角噴射之功能。 In addition, if a known ball joint is used as the pipe joint, it is impossible to avoid the communication between the linear injection passage hole and the wide-angle injection passage hole due to the orientation of the injection port, and the linear injection and wide-angle injection functions cannot be maintained.
本發明係對於具有直線噴射與廣角噴射之功能且切換地發揮兩功能之液體散布噴嘴，將可不損及直線噴射與廣角噴射之功能地變更噴射方向作為課題。 The present invention is directed to a liquid spray nozzle having a function of linear spraying and wide-angle spraying and switching to perform both functions without changing the spraying direction without impairing the functions of linear spraying and wide-angle spraying.
為解決上述問題，於本發明中，液體散布噴嘴包含：操作桿，其於內部具有液體供給路；通路切換用之閥；及噴霧頭，其具備設置於上述操作桿之前端之液體噴射口；上述液體供給路於較上述閥更為操作桿之後方，分支為由上述閥進行開閉之直線噴射通路與中心對稱地設置於該直線噴射通路之周圍之渦流產生通路， 將開啟上述閥時通過上述直線噴射通路之液體自上述噴射口直線噴射，將閉合上述閥時通過上述渦流產生通路之液體自上述噴射口廣角噴射，且對該液體散布噴嘴賦予以下特徵部。 In order to solve the above-mentioned problems, in the present invention, the liquid distribution nozzle includes: an operating lever having a liquid supply path inside; a valve for path switching; and a spray head having a liquid ejecting port provided at a front end of the operating lever; The liquid supply path branches behind a lever further than the valve, and branches into a linear ejection path that is opened and closed by the valve, and a swirl generation path that is symmetrically provided around the linear ejection path at the center. The liquid passing through the linear injection path when the valve is opened is linearly ejected from the injection port, and the liquid passing through the vortex generation path when the valve is closed is ejected from the injection port at a wide angle, and the following characteristics are provided to the liquid dispersion nozzle.
即，於上述操作桿與噴霧頭之間設置管接頭，以於前端具備可於單方向轉動之球狀部之第1構件、與具備使上述球狀部密接之凹球面之第2構件而構成該管接頭，於該管接頭之連結於上述操作桿之上述第1構件與裝入於上述噴霧頭之上述第2構件中分別獨立地形成上述直線噴射通路與渦流產生通路，且設為使該直線噴射通路及渦流產生通路之與第1構件及第2構件對向形成之連接口之一者較另一者之連接口於上述第1構件之轉動方向更長地延伸之形狀。 That is, a pipe joint is provided between the operation lever and the spray head, and the first member includes a first member that can rotate in one direction at a tip end, and a second member that includes a concave spherical surface that closely contacts the spherical portion. In the pipe joint, the first member connected to the operating lever and the second member installed in the spray head of the pipe joint respectively form the linear spray path and the vortex flow path independently, and are configured such that One of the connection openings formed by the linear ejection passage and the vortex flow passage opposite to the first member and the second member extends in a direction in which the first member extends longer than the connection opening of the other member.
該液體散布噴嘴較佳為設置可解除將彎曲之噴霧頭保持於彎曲終點之保持的彎曲姿勢之恢復限制機構。 It is preferable that the liquid dispersion nozzle is provided with a recovery restriction mechanism capable of releasing the bending posture of holding the curved spray head at the bending end point.
該彎曲姿勢之恢復限制機構亦可為例如已知之閉鎖機構等，但閉鎖機構雖於液體之散布中意圖將噴霧頭維持彎曲姿勢，但可能產生觸碰某些物體而恢復為筆直之姿勢的情況。 The recovery restriction mechanism of the bending posture may also be, for example, a known locking mechanism. However, although the locking mechanism intends to maintain the spray head in a curved posture during the dispersion of the liquid, it may return to a straight posture by touching some objects. .
因此，本發明亦一併提供一種避免產生此種故障之彎曲姿勢之恢復限制機構。 Therefore, the present invention also provides a recovery restriction mechanism that avoids such a bending posture that causes such a failure.
該彎曲姿勢之恢復限制機構係構成如下：於上述第1構件之外周安裝容許於固定角度範圍內正反旋轉之環狀構件，且於該環狀構件設置供上述連結件之第2構件側構成要素抵接之接觸面，於上述噴霧頭處於彎曲終點之狀態下使上述環狀構件旋轉至正轉方向終點時，上述接觸面阻止上述連結件之第2構件側構成要素之復位方向移動，且於使上述環狀構件旋轉至反轉方向終點時，解除上述接觸面對上述連結件之第2構件側構成要素之復位方向移動之阻止。 The restoring restraint mechanism of the bending posture is constituted as follows: a ring-shaped member that allows forward and reverse rotation within a fixed angle range is mounted on the outer periphery of the first member, and a second member-side structure is provided on the ring-shaped member for the connection member When the contact surface of the element abuts, when the annular head is rotated to the end of the forward rotation direction when the spray head is at the bending end point, the contact surface prevents the resetting direction of the second component-side component of the link from moving, and When the ring-shaped member is rotated to the end point in the reverse direction, the contact is prevented from moving in the reset direction of the second member-side component of the link.
本發明之液體散布噴嘴亦較佳為於分別設置於上述管接頭之第1 構件與第2構件之直線噴射通路與渦流產生通路各者之連接部之周圍，設置將上述球狀部與凹球面之間密封且自外部劃分液體供給路之密封構件。 The liquid dispersion nozzle of the present invention is also preferably provided in each of the first A seal member is provided around the connection portion of each of the linear ejection path and the vortex generation path of the member and the second member, and seals the spherical portion and the concave spherical surface and divides the liquid supply path from the outside.
上述第1構件可設為於上述管接頭之前端之球狀部之球之中心之兩側設置支軸，且可藉由以該支軸為支點而於單方向轉動。又，即便無支軸之結構，亦可設為可於單方向轉動。 The first member may be provided with support shafts on both sides of the center of the ball of the spherical portion at the front end of the pipe joint, and may be rotated in a single direction by using the support shaft as a fulcrum. Moreover, even if it is a structure without a support shaft, it can also be set to be able to rotate in one direction.
再者，本發明之適用對象中亦包含以上之專利文獻2中揭示之液體散布噴嘴，即，亦包含串聯配置地設置第1噴射口與第2噴射口，進而，於兩噴射口間設置吸氣孔，具備將自該吸氣孔吸入之氣體與液體混合後進行噴射之功能之液體散布噴嘴。 In addition, the applicable object of the present invention includes the liquid dispersion nozzle disclosed in the above Patent Document 2, that is, the first spray port and the second spray port are arranged in series, and a suction is provided between the two spray ports. The air hole is a liquid dispersing nozzle having a function of mixing the gas sucked from the air hole with the liquid and spraying.
本發明之液體散布噴嘴係於操作桿與噴霧頭之間，設置具備可以前端之球狀部之球之兩側之支軸為支點而轉動之第1構件之管接頭，且設為使形成於該管接頭之第1構件與第2構件之直線噴射通路及渦流產生通路之與第1構件及第2構件對向形成之連接口之一者於第1構件之轉動方向較長地延伸之形狀，故而，即便使第1構件回旋亦可維持直線噴射通路與渦流產生通路各自之連接狀態，藉此，可使噴射口之朝向進行變化。 The liquid dispersion nozzle of the present invention is located between the operating lever and the spray head, and is provided with a pipe joint having a first member that can be rotated by supporting shafts on both sides of the ball of the spherical portion at the front end as a fulcrum, One of the linear injection paths and vortex generation paths of the first member and the second member of the pipe joint, and one of the connection openings formed opposite to the first member and the second member extends in the direction of rotation of the first member. Therefore, even if the first member is rotated, the respective connection states of the linear injection passage and the vortex flow generation passage can be maintained, whereby the orientation of the injection port can be changed.
又，因將第1構件之轉動方向限制為單方向，故不存在形成於第1構件與第2構件之直線噴射通路與渦流產生通路裝錯地連接之情況。因此，即便變更噴射口之朝向，亦不會對直線噴射與廣角噴射之功能造成任何影響，從而不損及直線噴射與廣角噴射之功能。 In addition, since the rotation direction of the first member is limited to a single direction, there is no case where the linear injection passage and the vortex flow passage formed in the first member and the second member are connected in a wrong manner. Therefore, even if the orientation of the injection port is changed, the functions of the linear injection and the wide-angle injection will not be affected, and the functions of the linear injection and the wide-angle injection will not be impaired.
再者，設置上述彎曲姿勢之恢復限制機構，尤其，以可正反旋轉地安裝於上述第1構件之外周之上述環狀構件構成該彎曲姿勢之恢復限制機構者係使環狀構件作為止動部作動，從而可以簡單操作確實地阻止被彎曲之噴霧頭之意外之復位。 Furthermore, the restoration restriction mechanism for the bending posture is provided, and in particular, the restoration restriction mechanism for the bending posture is constituted by the annular member which is rotatably mounted on the outer periphery of the first member, and the annular member is used as a stop. The operation of the head can be simple operation to reliably prevent the accidental reset of the curved spray head.
又，於上述直線噴射通路與渦流產生通路之連接部之周圍，設置將未連接於通路之界面密封之密封構件者可將直線噴射通路與渦流產生通路之漏液抑制為最小限度。 In addition, a seal member that seals the interface not connected to the passage around the connection portion between the linear ejection passage and the vortex generation passage can minimize leakage of liquid from the linear ejection passage and the vortex generation passage.
又，已知設置第1噴射口、第2噴射口及吸氣孔且可將氣體吸入混合後進行噴射之液體散布噴嘴可獲得使自噴射口噴射之粒子之細霧隨風飛散之所謂漂移現象之抑制效果，於本發明中亦運用該特徵。 In addition, a liquid dispersion nozzle provided with a first injection port, a second injection port, and an air suction hole and capable of sucking and mixing gas and spraying is known to obtain a so-called drift phenomenon in which the fine mist of particles sprayed from the spray port is scattered with the wind. The suppression effect is also used in the present invention.

The sleeve 3a is used in combination with the second member 8, but may be formed separately from the second member 8.
本發明之液體散布噴嘴亦可為如下構造：如前述之專利文獻2所示，串聯配置地設置2個具有噴出口之噴板，且於該2個噴板間設置吸氣孔(未圖示)，將自該吸氣孔吸入之氣體與液體混合後進行噴射。 The liquid dispersion nozzle of the present invention may also have a structure as shown in the aforementioned Patent Document 2, two nozzle plates having ejection ports are arranged in series, and an air suction hole (not shown) is provided between the two nozzle plates. ), The gas sucked from the suction hole is mixed with the liquid and sprayed.

以上構成詳細記載於前述之專利文獻1或專利文獻2中，故而省略此處之詳細說明。 The above configuration is described in detail in the aforementioned Patent Document 1 or Patent Document 2, and therefore detailed descriptions thereof are omitted here.
繼而，對將本發明建立特徵之管接頭4進行說明。該管接頭4係包含：第1構件7(同時參照圖7)，其係於前端具備球狀部7a，且以設置於該球狀部之球之中心之兩側之支軸7b(參照圖4)為支點可於單方向(圖3中為仰角變化之方向)轉動；第2構件8，其具備使球狀部7a密接之凹球面8a；及後述之連結件11。 Next, the pipe joint 4 which characterizes the present invention will be described. The pipe joint 4 includes a first member 7 (refer to FIG. 7 at the same time), which is provided with a spherical portion 7a at the front end, and supports 7b (refer to the figure) provided on both sides of the center of the ball of the spherical portion 4) The fulcrum can be rotated in a single direction (the direction in which the elevation angle changes in FIG. 3); the second member 8 includes a concave spherical surface 8a that closely contacts the spherical portion 7a; and a connecting member 11 described later.
於該管接頭4之第1構件7與第2構件8，分別獨立地形成上述直線噴射通路6a與渦流產生通路6b，且使該直線噴射通路6a及渦流產生通路6b之與第1構件7及第2構件8對向形成之連接口之一者(於圖中為設置於第1構件7之圖7所示之連接口aj、bj)較另一者之連接口(於圖中為設置於第2構件8之連接口)於第1構件7之轉動方向更長。 The first member 7 and the second member 8 of the pipe joint 4 respectively form the above-mentioned linear injection path 6a and the vortex generation path 6b independently, and the linear injection path 6a and the vortex generation path 6b and the first member 7 and One of the connection ports formed oppositely by the second member 8 (the connection ports aj, bj shown in FIG. 7 provided in the first member 7 in the figure) is more than the connection port of the other (in the figure: The connection opening of the second member 8 is longer in the rotation direction of the first member 7.
因此，以支軸7b為支點，使第1構件7與第2構件8於期望範圍內相對地轉動時，設置於第1構件7與第2構件8之直線噴射通路6a與渦流產生通路6b之各者維持連接狀態。 Therefore, when the first member 7 and the second member 8 are relatively rotated within a desired range with the support shaft 7b as a fulcrum, the linear injection path 6a and the vortex generation path 6b provided in the first member 7 and the second member 8 are provided. Each one remains connected.
圖6中表示使噴霧頭3轉動，將噴射方向變更為傾斜向下之狀態。如此般，本發明之液體散布噴嘴1可一面藉由設置類似球接頭之管接頭4而確保直線噴射與廣角噴射之功能，一面使噴射口之朝向變化。 FIG. 6 shows a state in which the spray head 3 is rotated to change the spray direction to an oblique downward direction. In this way, the liquid dispersion nozzle 1 of the present invention can change the orientation of the spray port while ensuring the functions of linear spray and wide-angle spray by providing a pipe joint 4 similar to a ball joint.
圖3、圖4、圖6之10係配置於內管2a之前端側外周與第1構件7之後部側內周之間之液封環。該液封環10係以導引內管2a之端側之移動，且消除液體供給路6通過管接頭4對於操作桿2之連接部之間隙連 通至外部為目的而設置，但並非將本發明建立特徵之要素。 10 of FIG. 3, FIG. 4, and FIG. 6 are liquid sealing rings arranged between the outer periphery of the front end side of the inner tube 2a and the inner periphery of the rear side of the first member 7. The liquid seal ring 10 guides the movement of the end of the inner tube 2a, and eliminates the gap between the liquid supply path 6 and the connection portion of the operation rod 2 through the pipe joint 4. It is provided for the purpose of external access, but it is not an element that characterizes the present invention.
圖3、圖4、圖6之11係於第1構件7連接噴霧頭3之連結件。該連結件11包含被覆於第1構件之球狀部7a之外周之套筒11a、及卡合於套管3a且螺合於套筒11a之蓋形螺母11b，且由套筒11a支持第1構件之球狀部之外周之支軸7b。 11 in FIG. 3, FIG. 4, and FIG. 6 are connected members of the first member 7 to the spray head 3. The connecting member 11 includes a sleeve 11a covering the outer periphery of the spherical portion 7a of the first member, and a cap nut 11b that is engaged with the sleeve 3a and is screwed to the sleeve 11a. The sleeve 11a supports the first The support shaft 7b on the outer periphery of the spherical portion of the member.
圖3、圖4、圖6之12係將球狀部7a之外表面與凹球面8a之間之界面密封之密封構件。又，13係將球狀部7a與套筒11a之間之界面、及套管3a與套筒11a之間之界面密封之O型環。該等構件係為防止漏液或來自外部之異物侵入而設置，但密封構件12僅為較佳之要件。又，O型環13亦可置換成其他密封構件，設置點亦並非限制於圖示之位置。總之，只要可將內部之流路與外部之間密封即可。 12 of FIGS. 3, 4, and 6 are sealing members that seal the interface between the outer surface of the spherical portion 7a and the concave spherical surface 8a. 13 is an O-ring that seals the interface between the spherical portion 7a and the sleeve 11a, and the interface between the sleeve 3a and the sleeve 11a. These members are provided to prevent leakage of liquid or foreign matter from the outside, but the sealing member 12 is only a preferable element. The O-ring 13 may be replaced with another sealing member, and the setting point is not limited to the position shown in the figure. In short, as long as the internal flow path can be sealed from the outside.
再者，於示例之液體散布噴嘴1，使設置於第1構件7之直線噴射通路6a與渦流產生通路6b之出口側如圖3所示朝向出口扇狀地擴展，如圖7所示，使於球狀部7a之外表面(球面)開口之連接口aj、bj較於第2構件之凹球面8a開口之連接口於第1構件7之轉動方向更長地延伸，但亦可如圖9所示，使第2構件8側之連接口較第1構件7側之連接口於第1構件7之轉動方向更長地延伸。此時，未圖示之渦流產生通路6b之連接口亦同樣地使於第2構件之凹球面8a開口之連接口變長。 Furthermore, in the liquid dispersion nozzle 1 of the example, the outlet sides of the linear spray passage 6a and the vortex generation passage 6b provided in the first member 7 are fan-shapedly expanded toward the outlet as shown in FIG. The connection openings aj, bj that are opened on the outer surface (spherical surface) of the spherical portion 7a are longer in the rotation direction of the first member 7 than the connection openings of the concave spherical surface 8a of the second member, but can also be as shown in FIG. 9 As shown, the connection opening on the side of the second member 8 is made longer in the rotation direction of the first member 7 than the connection opening on the side of the first member 7. At this time, the connection port of the eddy current generation passage 6b (not shown) also has a connection port that opens in the concave spherical surface 8a of the second member in the same manner.
又，密封構件12係設置於第2構件8側，但亦可如圖8所示，安裝於第1構件7之球狀部7a。該構造亦可藉由以密封構件12包圍直線噴射通路6a與渦流產生通路6b之連接部而將漏液抑制為最小限度。 The sealing member 12 is provided on the second member 8 side, but may be attached to the spherical portion 7 a of the first member 7 as shown in FIG. 8. This structure can also minimize the leakage by surrounding the connection portion between the linear ejection path 6 a and the vortex generation path 6 b with the sealing member 12.
此外，示例之液體散布噴嘴係以支軸7b為支點進行第1構件7之單方向轉動，但第1構件7之單方向轉動亦可以將轉動方向上延伸之導引槽與由該槽導引著僅於單方向移動之構件等組合而成之其他結構實現。 In addition, the liquid dispersing nozzle in the example uses the support shaft 7b as the fulcrum to perform the unidirectional rotation of the first member 7, but the unidirectional rotation of the first member 7 can also guide the guide groove extending in the rotation direction and be guided by the groove. It is realized by other structures which are combined only with components moving in one direction.
於圖10~圖16中，表示本發明之液體散布噴嘴之較佳之形態之 具體例。圖10之液體散布噴嘴1具備於彎曲之終點保持噴霧頭3之彎曲姿勢之恢復限制機構14。 10 to 16 show a preferred form of the liquid dispersion nozzle of the present invention. Specific examples. The liquid dispersion nozzle 1 shown in FIG. 10 is provided with a recovery restriction mechanism 14 that maintains the bending posture of the spray head 3 at the end point of bending.
圖示之彎曲姿勢之恢復限制機構14係將環狀構件15(同時參照圖14、圖15)、及設置於該環狀構件15與鎖蓋16(其亦同時參照圖14、圖15)之間之導件17組合而構成。鎖蓋16與第1構件7係考慮管接頭4之組裝性而分割。 The recovery restriction mechanism 14 in the bending posture shown in the figure is a ring member 15 (refer to FIGS. 14 and 15 at the same time), and a ring member 15 and a lock cover 16 (also refer to FIGS. 14 and 15 at the same time). The intermediate guide 17 is configured in combination. The lock cover 16 and the first member 7 are divided in consideration of the assemblability of the pipe joint 4.
若為該分割結構，可使鎖蓋16之外徑大於球狀部7a之外徑，且使該鎖蓋16之上側部分於噴霧頭3未彎曲之圖10、圖11之狀態時頂接於套筒11a之上側部分。於該狀態下，套筒11a之上側開口被鎖蓋16封閉，從而不易引起塵埃等對球狀部7a之滑動面侵入，但鎖蓋16與第1構件7亦可一體地形成。 With this split structure, the outer diameter of the lock cover 16 can be larger than the outer diameter of the spherical portion 7a, and the upper part of the lock cover 16 can be abutted on the state of the spray head 3 without bending as shown in Figs. Upper part of the sleeve 11a. In this state, the upper opening of the sleeve 11 a is closed by the lock cover 16, so that it is difficult for dust or the like to enter the sliding surface of the spherical portion 7 a. However, the lock cover 16 and the first member 7 may be integrally formed.
再者，鎖蓋16係卡口嵌合於第1構件7之外周而固定。鎖蓋16對第1構件7之卡口嵌合係利用設置於鎖蓋16之內面之突起16a(參照圖14)、與設置於第1構件7之外周之導槽7c(參照圖15)而進行，但鎖蓋16之安裝(對第1構件7之定位固定)法不限定於卡口嵌合。 In addition, the lock cover 16 is bayonet-fitted and fixed to the outer periphery of the first member 7. The bayonet fitting of the lock cover 16 to the first member 7 uses a protrusion 16a (see FIG. 14) provided on the inner surface of the lock cover 16 and a guide groove 7c (see FIG. 15) provided on the outer periphery of the first member 7. However, the method of mounting the lock cover 16 (positioning and fixing the first member 7) is not limited to the bayonet fitting.
環狀構件15係以容許在固定角度範圍內之正反旋轉之方式安裝於鎖蓋16之外周。 The ring member 15 is attached to the outer periphery of the lock cover 16 in such a manner as to allow forward and reverse rotation within a fixed angle range.
於鎖蓋16之外周，設置有與設置於環狀構件15之內周面之突起17a(參照圖14)組合而構成導件17之導槽17b(參照圖15、16)，且將突起17a***至該導槽17b中，而將環狀構件15安裝於鎖蓋16之外周。 A guide groove 17b (see FIGS. 15 and 16) is formed on the outer periphery of the lock cover 16 in combination with a protrusion 17a (see FIG. 14) provided on the inner peripheral surface of the annular member 15, and the protrusion 17a is provided. The ring groove 15 is inserted into the guide groove 17 b, and the ring member 15 is attached to the outer periphery of the lock cover 16.
導槽17b係伴隨周向位移與軸向位移之槽，且若因該導槽17b之導引效應而使環狀構件15旋轉，則鎖蓋16上之該環狀構件15於軸向進退。 The guide groove 17b is a groove accompanying a circumferential displacement and an axial displacement, and if the annular member 15 is rotated due to the guiding effect of the guide groove 17b, the annular member 15 on the lock cover 16 advances and retreats in the axial direction.
於環狀構件15，設置有於使用狀態下觸及第1構件7側之接觸面15b。該接觸面15b係若於噴霧頭3處於彎曲終點之狀態下使環狀構件15旋轉至正轉方向(圖中該方向係自後部側觀察液體散布噴嘴時成為 逆時針旋轉之方向)終點，則如圖13所示，移動至前進位置。 The ring-shaped member 15 is provided with a contact surface 15 b that touches the first member 7 side in the use state. This contact surface 15b is formed when the annular member 15 is rotated to the forward rotation direction when the spray head 3 is at the bending end point (the direction in the figure is when the liquid dispersion nozzle is viewed from the rear side). The counterclockwise rotation direction) end point moves to the forward position as shown in FIG. 13.
若連結件11之構成要素(圖中其為套筒11a)欲沿復位方向移動(朝向復位方向旋轉)，則移動至前進位置之接觸面15b頂接於該套筒11a，藉此確實地阻止噴霧頭3自彎曲終點意外地回位。 If the constituent elements of the connecting member 11 (the sleeve 11a in the figure) are to be moved in the reset direction (rotated toward the reset direction), the contact surface 15b moved to the forward position abuts on the sleeve 11a, thereby reliably preventing The spray head 3 returns accidentally from the end of the bend.
又，若使該環狀構件15旋轉至反轉方向終點，則接觸面15b如圖11所示地後退，從而解除該接觸面15b對連結件11之第2構件側構成要素之復位方向移動之阻止。 When the ring-shaped member 15 is rotated to the end in the reverse direction, the contact surface 15b is retracted as shown in FIG. 11, and the contact surface 15b is released from moving in the reset direction of the second member-side component of the coupling 11. prevent.
再者，圖10之液體散布噴嘴係使連結件之套筒11a之形狀與圖3不同，且配置於將密封第1構件之球狀部7a之外周之O型環13***至套筒11a之內周之階差部之扣環18、球狀部7a之外表面、及第2構件8之端部之間，但O型環13之設置點並非限制於圖示之位置，只要為可達成球狀部7a之外周密封之目的之位置即可。 In addition, the liquid distribution nozzle of FIG. 10 is different from that of FIG. 3 in the shape of the sleeve 11 a of the coupling member, and is arranged to insert an O-ring 13 that seals the outer periphery of the spherical portion 7 a of the first member into the sleeve 11 a. Between the buckle 18, the outer surface of the spherical portion 7a, and the end of the second member 8 in the step portion of the inner periphery, but the setting point of the O-ring 13 is not limited to the position shown in the figure, as long as it can achieve a spherical shape The position of the outer periphery of the portion 7a may be sealed.
圖10之19係覆蓋噴霧頭3之連蓋帽，且其安裝於連結件11之蓋形螺母11b。 19 of FIG. 10 is a connecting cap covering the spray head 3, and it is mounted on the cap nut 11b of the connecting member 11.
由於圖10之液體散布噴嘴之其他構成並無與圖3之液體散布噴嘴特別不同之處，故對主要要素標註相同符號並省略說明。 Since the other components of the liquid distribution nozzle of FIG. 10 are not particularly different from those of the liquid distribution nozzle of FIG. 3, the same elements are denoted by the same reference numerals and description thereof is omitted.
