detailed description

As shown in Figures 2 to 7, the active push-pull mechanism provided by the utility model includes a base plate 1, a push rod assembly 2 and a panel 3, and the push rod assembly 2 includes a push rod 21, a button 22 and a guide column 23, and the base plate 1 There is a chute 11, and the push rod 21 is arranged between the base plate 1 and the panel 3, and the push rod 21 is provided with a bar-shaped hole 211; the button 22 penetrates from the panel 3, passes through the bar-shaped hole 211, and then inserts into the base plate 1, and the guide post 23 extends from the lower surface of the push rod 21 and is located in the chute 11 of the bottom plate 1 , so that the guide post 23 can slide along the chute 11 . The length of the strip hole 211 can be designed according to the required push-pull length.

The button 22 includes a head 221, a stem 222 and an embedded portion 223. The head 221 and the embedded portion 223 are connected by the stem 222. The projected areas of the embedded portion 223 and the head 221 on the bottom plate 1 are larger than those of the stem 222 on the bottom plate 1. projected area on . That is, the button 22 is a structure with two large ends and a small middle. The rod part 222 is cylindrical, and the diameter of the rod part 222 is smaller than the width of the bar-shaped hole 211 , so that the rod part 222 can slide in the bar-shaped hole 211 .

One end of the chute 11 is provided with a blind hole 12, the embedded part 223 is at least partially embedded in the blind hole 12, and the first elastic member 4 is arranged between the bottom of the embedded part 223 and the bottom surface of the blind hole 12, and the height of the embedded part 223 is less than The depth of the blind hole 12. Under normal conditions, only part of the embedding part 223 is embedded in the blind hole 12 . At this time, due to the blocking effect of the embedding part 223 , the entire push rod 21 cannot move. When the button 22 is pushed down, the embedded part 223 is completely embedded in the blind hole 12, and the rod part 222 can slide in the slide groove 11, so that the whole push rod 21 can move.

The strip-shaped hole 211 includes a strip-shaped portion 2111 and an enlarged portion 2112. The guide post 23 is located at one end of the strip-shaped portion 211, and the enlarged portion 2112 communicates with the other end of the strip-shaped portion 2111. In the width direction of the push rod 21, the enlarged portion 2112 The size of the strip part 2111 is larger than that of the bar-shaped part 2111 , the embedded part 223 matches the enlarged part 2112 , and the embedded part 223 can pass through the enlarged part 2112 and be embedded into the blind hole 12 . The embedding part 223 is a columnar structure, and its diameter is greater than the width of the bar-shaped hole 211 , so that the embedding part 223 cannot slide in the bar-shaped hole 211 to play a blocking role.

One end of the push rod 21 is provided with a push button 24 to facilitate pushing the push rod 21 .

A second elastic member 5 is disposed between the end of the sliding slot 11 away from the blind hole 12 and the guide post 23 , so as to facilitate the reset of the button 22 . Because the second elastic member 5 can push the guide post 23 to move along the bar-shaped hole 211 toward the side where the push button 24 is located, so that the push rod 21 slides correspondingly, so that the enlarged part 2112 reaches directly above the embedded part 223. At this time, Under the action of the elastic force of the first elastic member 4 , the embedded portion 223 springs up and snaps into the enlarged portion 2112 , at this time, the push rod 21 cannot move.

The bottom plate 1 is also provided with several first through holes 13 positioned at both sides of the chute 11, and the panel 3 is provided with several second through holes 31 positioned at both sides of the chute 11, and the panel 3 and the bottom plate 1 are inserted through the second The through hole 31 is connected with the fastener of the first through hole 13. During the whole process, the bottom plate 1 and the panel 3 are fixed, and only the push rod assembly 2, the first elastic part 4 and the second elastic part 5 will move. In this embodiment, both the first elastic component 4 and the second elastic component 5 are springs.

The panel 3 is also provided with a third through hole 32 through which the rod 222 of the button 22 can pass, and the head 221 is located above the panel 3 to facilitate the up and down movement of the button 22 .

The chute 11 is disposed in the middle of the bottom plate 1 , and the extending direction of the chute 11 is parallel to the length direction of the bottom plate 1 . The guide post 23 is located at the central area of the push rod 21 . The length of the push rod 21 is greater than the lengths of the bottom plate 1 and the panel 3 .

The working principle of the utility model is: press the head 221 firmly, the second elastic part 5 is compressed, the embedded part 223 is completely inserted into the blind hole 12, and the blocking is released. At this time, under the elastic force of the second elastic part 5, The push rod 21 actively moves backward, thereby realizing the movement of the push rod 21 . When it is necessary to move the push rod 21 forward, push the push button 24 hard, so that the second elastic member 5 is compressed, and the push rod 21 is moved forward, so that the enlarged part 2112 reaches the right above the embedded part 223, and the embedded part 223 Under the action of the elastic force of the first elastic member 4, it bounces up and embeds into the enlarged part 2112, returns to the original position, plays a blocking role, and the push rod 21 returns to the original position.

In a word, the utility model has a simple structure. When in use, first press the button 22 downwards, and the push rod 21 can be pushed backwards, and then forcefully push the push rod 21 forward, and the button 22 moves upwards and returns to the original position, realizing the reset. In this way, the push-pull operation of the push rod 21 can be realized through simple operations, which greatly saves man-hours and enables operators to use the product more conveniently.

According to the disclosure and teaching of the above specification, those skilled in the art to which the present utility model belongs can also make appropriate changes and modifications to the above embodiment. Therefore, the utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model.
