Preferably, one end of the elastic member 60 is received in the spring receiving groove 33 of the plastic nut 30, thereby forming a good positioning effect on the elastic member 60.
請參閱圖5所示，藉由上述各元件的組合，可將此致動器8裝設在一電動病床、椅、桌、窗等相關設備上，其中管體10的固定孔11和後支座86將被螺栓等固定元件穿接固定(參見圖1所示)，在使用過程中致動器8正在做推力作動時，即導螺桿84以順時針方向進行旋轉，而防火型伸縮管1將相對於外管83作朝外側伸出的動作，因為發生火災導致塑膠螺帽30產生燒毀失效，由於管體10受力推向扣環50和耐火螺帽40，在耐火螺帽40受力的情況下將不產生自轉，在導螺桿84以順時針方向進行旋轉時，將驅動耐火螺帽40、扣環50、轉接座20和管體10一起持續朝向外管83的外側伸出，而使被承載的使用者和物品不會產生瞬間快速跌落的情況，進而起到保護作用。Referring to FIG. 5, the actuator 8 can be mounted on an electric bed, a chair, a table, a window, and the like by a combination of the above components, wherein the fixing hole 11 and the rear bearing of the pipe body 10 are provided. 86 will be fixed by a fixing member such as a bolt (see FIG. 1). When the actuator 8 is performing thrust operation during use, the lead screw 84 rotates in a clockwise direction, and the fireproof telescopic tube 1 will The action of extending outwardly relative to the outer tube 83 causes the plastic nut 30 to fail to burn due to a fire. Since the tube 10 is forced to push the buckle 50 and the refractory nut 40, the refractory nut 40 is forced. In this case, no rotation will occur, and when the lead screw 84 is rotated in the clockwise direction, the fire resistant nut 40, the buckle 50, the adapter 20 and the tubular body 10 are continuously extended toward the outside of the outer tube 83, and The user and the item to be carried are not subjected to an instant rapid drop, thereby providing protection.
請參閱圖6所示，在使用過程中致動器8正在做拉力作動時，即導螺桿84以逆時針方向進行旋轉，而防火型伸縮管1將相對於外管83作朝內側縮入的動作，因為發生火災導致塑膠螺帽30產生燒毀失效，此時耐火螺帽40的右側端貼接在轉接座20的擋部25，在耐火螺帽40受力的情況下將不產生自轉，在導螺桿84以逆時針方向進行旋轉時，將驅動耐火螺帽40、轉接座20和管體10一起持續朝向外管83的內側縮入，而使被承載的使用者和物品不會產生瞬間快速跌落的情況，進而起到保護作用。因此，不管是致動器8做推力或拉力的作動，本創作的防火型伸縮管1皆能夠獲得應有的保護。Referring to FIG. 6, when the actuator 8 is performing the pulling operation during use, the lead screw 84 rotates in the counterclockwise direction, and the fireproof telescopic tube 1 is retracted inwardly relative to the outer tube 83. The action causes the plastic nut 30 to fail to burn due to a fire. At this time, the right end of the fire-resistant nut 40 is attached to the blocking portion 25 of the adapter seat 20, and the fire-resistant nut 40 will not rotate when the force is applied. When the lead screw 84 rotates in the counterclockwise direction, the refractory nut 40, the adapter 20 and the tubular body 10 are continuously pushed together toward the inner side of the outer tube 83, so that the loaded user and the article are not generated. The situation of rapid drop in an instant, and thus play a protective role. Therefore, regardless of the actuation of the actuator 8 by the thrust or the pulling force, the fireproof telescopic tube 1 of the present invention can obtain the protection it deserves.
請參閱圖7所示，本創作的防火型伸縮管除了可為上述外，亦可如本實施例之型態，其與前述實施例的差異在於塑膠螺帽30a的端部成型有一環形叉部35a，耐火螺帽40a朝向塑膠螺帽30a的端面設有與叉部35a相互插接固定的一叉槽42a，藉以確保塑膠螺帽30a和耐火螺帽40a能夠保持在一適當的間隔距離，在常態下可使耐火螺帽40a不與導螺桿84作傳動接觸，如此亦具有前述實施例的等同效果。Referring to FIG. 7 , the fireproof telescopic tube of the present invention may be in the form of the embodiment, except that it may be different from the foregoing embodiment in that the end of the plastic nut 30a is formed with a circular fork. 35a, the end surface of the refractory nut 40a facing the plastic nut 30a is provided with a fork groove 42a which is inserted and fixed with the fork portion 35a, thereby ensuring that the plastic nut 30a and the refractory nut 40a can be maintained at an appropriate distance. Normally, the refractory nut 40a is not in driving contact with the lead screw 84, and thus has the equivalent effect of the foregoing embodiment.
綜上所述，本創作之用於致動器的防火型伸縮管，確可達到預期之使用目的，而解決習知之缺失，又因極具新穎性及進步性，完全符合新型專利申請要件，爰依專利法提出申請，敬請詳查並賜准本案專利，以保障創作人之權利。In summary, the fire-proof telescopic tube for the actuator of the present invention can achieve the intended purpose of use, and solve the lack of the conventional, and because of the novelty and progress, fully meet the requirements of the new patent application.
