Description

Slide rail displacement positioning device

The utility model relates to a slide rail displacement positioning device, in particular to a positioning device for restricting the sliding rail from being pulled out and folded by the elastic resetting capability, and simultaneously releasing the positioning state of the sliding rail pulling and folding.

According to the current slide design, the slide rail will not be easily folded when it is pulled out, that is, the positioning is formed. Generally, the elastic piece is mounted on the slide rail, and the slide rail is pulled by the groove provided on the elastic piece. After a certain distance, it is positioned in the groove. If the sliding speed of the slide rail is too fast, it will instantly pass over the groove and cannot achieve the positioning effect.

Therefore, how to solve the above-mentioned problems and shortcomings is the subject of research and development that the relevant industry is eager to develop.

The main purpose of the present invention is to utilize the frame body and the stop piece provided by the stopper and the positioning space formed therebetween, so that when the positioning member is displaced, only the elastic displacement of the stop piece is pushed, but It is indeed subject to the frame stop, so that when the stopper and the positioning member are respectively mounted on the slide rail group, the outer rail and the inner rail of the slide rail group can be surely positioned.

The second object of the present invention is to use the frame of the stopper to press the stopper piece to release the positioning state of the positioning member at the same time, which is convenient for the user to use.

In order to achieve the above object, the slide rail displacement positioning device of the present invention is provided with a slide rail group, a stopper member and a positioning member, the slide rail group has an inner rail and an outer rail, and the outer rail sleeve is sleeved on the outer side of the inner rail to make the inner rail The outer rail extends and collapses; the stopper has a frame body and a stopper piece, and the two ends of the frame body are respectively formed with a fixed end and a rear stop end, and the fixed end and the rear end end are connected by a resilient arm, and The two ends of the stop piece are respectively formed with a connecting end and a front stop end. The connecting end is connected to the fixed end of the frame body, and the front stop end extends toward the rear stop end, and is formed with a positioning space spaced apart from the rear stop end. The positioning member has a fixing portion and a positioning portion bent and extended laterally of the fixing portion; the fixed end of the stopping member is positioned on the inner rail of the sliding rail group, and the fixing portion of the positioning member is fixed to the outer rail of the sliding rail group And the positioning portion of the positioning member is directly facing the stopper piece of the stopper. When the inner rail extends according to the outer rail, the positioning portion first presses the stopper piece to cause elastic displacement of the stopper piece, and the positioning portion is formed at the positioning portion. After entering the positioning space of the stopper, the stopper piece will have a displacement due to elasticity Ability to return to an original reset, and thus the positioning portion is positioned after the frame is formed with an end stop positioned between the stop state prior to the end flaps only.

In the above-mentioned slide rail displacement positioning device, the stopper member is formed by integral stamping, and the elastic arm of the stopper member is laterally bent and extended with a pressing arm, and the end of the pressing arm abuts against the fixing of the stopper piece. When the pressing arm is pressed by the external force, the frame body and the stopping piece will approach the inner rail at the same time, and the positioning of the rear stop end and the front stop end to the positioning member is released. State, let the inner rail of the rail group extend and fold according to the outer rail.

In the above-mentioned slide rail displacement positioning device, the surface between the fixed end and the rear stop end of the stop piece is recessed with an accommodating space for accommodating the end of the pressing arm.

Referring to the first to fifth figures, it can be clearly seen from the figure that the present invention is provided with a slide group 1, a stopper 2 and a positioning member 3, wherein:

The slide rail group 1 has an inner rail 11 and an outer rail 12, and the outer rail 12 is sleeved on the outer side of the inner rail 11, so that the inner rail 11 extends and folds according to the outer rail 12.

The stopper 2 is formed by integral stamping, and has a frame body 21 and a stopper piece 22. The two ends of the frame body 21 are respectively formed with a fixed end 211 and a rear stop end 212, and the fixed end 211 and the rear stop end are respectively formed. The two ends of the stop piece 22 are respectively connected with a connecting end 221 and a front stop end 222. The connecting end 221 is connected to the fixed end 211 of the frame 21, and the front stop end 222 is connected. The rear end stop end 212 extends and is spaced apart from the rear stop end 212 to form a positioning space 23; further, the elastic arm 213 of the stopper 2 is laterally bent and extends with a pressing arm 214, and the end of the pressing arm 214 is abutted. The surface between the fixed end 211 and the rear stop end 212 of the stop piece 22 is recessed, and the receiving space 223 for receiving the end of the pressing arm 214 is recessed on the surface between the fixed end 211 and the rear stop end 212.

The positioning member 3 has a fixing portion 31 and a positioning portion 32 that is bent and extended laterally of the fixing portion 31;

The fixing end 211 of the stopping member 2 is provided with a positioning hole 215. The inner rail 11 of the sliding rail group 1 is provided with a fixing post 111. The fixing hole 215 is riveted to the fixing post 111 to form a positioning, and the stopping member 2 The stop end 212 extends from the other side of the positioning space 23 to the limiting piece 216. The inner rail 11 is disposed on the side of the fixed post 111 with a blocking piece 112, and the limiting piece 216 is located below the blocking piece 112. Moreover, the fixing portion 31 of the positioning member 3 is fixed to the outer rail 12 of the slide rail group 1, and the positioning portion 32 of the positioning member 3 is directly opposite to the stopper piece 22 of the stopper member 2.

Referring to FIG. 5 to FIG. 10 , as shown in FIG. 6 to FIG. 8 , when the inner rail 11 extends according to the outer rail 12 , the stopper 2 and the positioning member 3 will follow the inner rail 11 and the outer rail. The extension of the positioning member 32 is relatively close. At this time, the positioning portion 32 of the positioning member 3 first presses the stopper piece 22 to cause the elastic displacement of the stopper piece 22 toward the surface of the inner rail 11 to enter the stopper 2 at the positioning portion 32. After the positioning space 23, the stop piece 22 will return to the original position due to the resetting capability of the elastic displacement, thereby positioning the positioning portion 32 after the frame body 21 and the stop end 212 and the stop end 22 of the stop piece 22 When the positioning portion 32 is pressed against the stopper piece 22, the frame body 21 does not approach the surface of the inner rail 11, so that the positioning portion 32 can be stopped by the rear stopper end 212. Referring to the ninth and tenth diagrams, when the inner rail 11 and the outer rail 12 of the slide rail group 1 are to be released, the pressing arm 214 is pressed, and the frame 21 and the stop end 212 and the stop are stopped. When the stop end 222 of the piece 22 approaches the inner rail 11 at the same time, the positioning state of the frame body 21 to the positioning member 3 can be released, and the inner rail 11 of the slide rail group 1 can be extended and folded according to the outer rail 12.
