When the inner rail 14 and the middle rail 16 of the aforementioned slide rail 10 are pulled out relative to the outer rail 12, preferably, the inner rail 14 and the middle rail 16 can be synchronously linked when they are pulled out from the outer rail 12. , but the synchronous and interlocking device is not the focus of the invention of the present application, nor is it a pioneering technology. In the field of such slide rail products, it is a known technology and will not be disclosed in this application. And as shown in Figure 5, when the inner rail 14 and the middle rail 16 are pulled out synchronously, the actuating part 42 of the actuator 30 of the chain lock 26 will be continuously resisted by the front end of the middle rail 16 and the rail body. Push and move back into the upper chamber 38 of the seat body 28. At the same time, the linkage part 46 of the actuator 30 is displaced from a first position to a second position, and the locking bar 50 is also moved by the linkage part. 46 drives the displacement, and the linkage part 46a of the second actuator 30a of the second chain lock 26a is linked by the lock bar 50, so that the second actuator 30a of the second chain lock 26a is displaced accordingly, Then the second latching portion 44a of the second actuator 30a can protrude from the lower chamber 40a of the second base 28a and is opposite to the second stopper 32a of the inner rail 14a of the second sliding rail 10a , so as to block the second stopper 32a by means of the second locking part 44a, thereby restricting the movement of the inner rail 14a of the second slide rail 10a, so as to prevent the opening of the second slide rail 10a, so as to achieve the safe use of chain locking Effect.

Referring to Fig. 6, taking the above-mentioned slide rail 10 as an example, the second preferred embodiment of the present invention also includes a push piece 200 fixed on the front end of the middle rail 16, and connected to the inner rail 14 relative to the A stopper 202 of the locking part 44, wherein the pusher 200 has an inclined push surface 204 relative to the actuation part 42 of the actuation part 30 of the chain lock 26, so that the actuation of the actuation part 30 The moving part 42 is more easily pushed by the push surface 204 of the push piece 200 to be displaced. Thereby, when the middle rail 16 of the slide rail 10 is pulled out relative to the outer rail 12 along with the inner rail 14 , the actuating part 42 of the actuating member 30 can first be pushed and displaced by the pushing surface 202 of the pushing member 200 , and start the locking function of the chain lock.

Referring to Fig. 7, taking the aforementioned slide rail 10 as an example, the third preferred embodiment of the present invention includes a push piece 300 fixedly connected to the front end of the inner rail 14, and is connected to the inner rail 14 oppositely A stopper 302 on the locking portion 44, wherein the pusher 300 has an inclined push surface 304 relative to the actuating portion 42 of the actuating member 30 of the chain lock 26, which is also conducive to the actuation The actuating portion 42 of the push piece 30 is pushed by the push surface 304 of the push piece 300 to be displaced.

Referring to FIG. 8 , taking the aforementioned slide rail 10 as an example, the fourth preferred embodiment of the present invention also includes a pull handle 400 connected to the inner rail 14 , the pull handle 400 includes an upper side portion 402 opposite to the The lower side portion 404 of the upper side portion 402 , wherein one end of the upper side portion 402 is provided with a push piece 406 opposite to the actuating portion 42 of the actuating piece 30 of the chain lock 26 . One end of the lower side portion 404 is connected to a stopper 408 , and the stopper 408 is opposite to the locking portion 44 . Preferably, the push piece 406 has an inclined push surface 410 relative to the actuating part 42 of the actuating part 30 of the chain lock 26, so that the actuating part 42 of the actuating part 30 is pushed by the pushing part 406 The pushing surface 410 pushes the displacement.

In addition, because the inner rail 14 and the middle rail 16 of the aforementioned slide rail 10 have a synchronous and interlocking relationship when they are pulled out from the outer rail 12, that is, if the middle rail 16 can be locked, the inner rail 14 will also be locked. will not be pulled out. Based on this, as shown in FIG. 9 , the fifth preferred embodiment of the present invention includes a stopper 500 affixed to the front end of the middle rail 16 , and the stopper 500 is opposite to the actuating member 30 of the chain lock 26 The locking part 44. Thereby, when the middle rail 16 of the sliding rail 10 is blocked by the catch portion 44 of the actuating member 30 of the chain lock 26 through the blocking member 500 , the middle rail 16 and the inner rail 14 are locked together.

As shown in FIG. 10 , the sixth preferred embodiment of the present invention is a continuation of the fifth embodiment. In addition to fixing the stopper 500 at the front end of the middle rail 16 , it also includes a stopper 500 fixed at the front end of the middle rail 16 A push piece 600 , the push piece 600 is opposite to the actuating portion 42 of the actuating piece 30 of the chain lock 26 .
