[0002] The guiding structure of the guide rail pair mainly consists of guide rail, slider, rolling elements, reverser, retainer, etc. The rolling elements circulate between the raceways of the guide rail and the slider to achieve the guiding function.
[0003] The existing guide structure of the guide rail pair is prone to collision with the outermost structure when it moves to the outermost position. After long-term reciprocating motion, the collision is prone to positional displacement and friction between the components, which affects its service life. To solve the above problems, this application proposes a new type of rolling linear guide rail pair guide structure. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a novel rolling linear guide pair guiding structure, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.
[0005] To achieve the above objectives, this application adopts the following technical solution: a novel rolling linear guide pair guide structure, including a track, a slider slidably mounted on the outer wall of the track, a circular hole opened on the outer side of the slider, one end of a return spring fixedly connected to the inner wall of the circular hole, the other end of the return spring fixedly connected to an abutment, a square hole opened on the outer side of the track, an insert block adapted to be inserted into the inner wall of the square hole, a side plate fixedly mounted on the outer wall of the insert block, a circular groove opened on the inner wall of the side plate, and a pressure sensor installed on the inner wall of the circular groove.
[0006] In a preferred embodiment, the abutment is slidably connected to the inner wall of the circular hole, the outer diameter of the abutment is adapted to the inner diameter of the circular hole, and a limit rod is fixedly installed on the inner side of the abutment, and the limit rod is slidably connected to the inner wall of the slider.
[0007] By adopting the above technical solution, the abutment can be retracted into the inner wall of the round hole when subjected to compressive force, thereby adjusting the return spring to be in a stressed state, and the limiting rod can be used to limit the movement of the abutment to ensure that it does not deviate from its position.
[0008] In a preferred embodiment, a track groove is provided through one side of the slider, and the inner wall size of the track groove is adapted to the shape of the track.
[0009] By adopting the above technical solution, the slider can be stably slid on the outer wall of the track, thereby achieving position adjustment and ensuring the stability of the slider during movement.
[0010] In a preferred embodiment, both the track and the side plate have mating grooves at their bottoms.
[0011] By adopting the above technical solution, the track can be stably installed at the installation site, ensuring the stability of the connection.
[0012] In a preferred embodiment, the top of the insert block has a through hole, the inner wall of the track has multiple mounting holes, the through hole corresponds to one of the mounting holes, and the side plate is disposed on the outer wall of the track.
[0013] By adopting the above technical solution, the insert block can be synchronously positioned using the bolts used to fasten the track, ensuring that it can be stably set on the inner wall of the square hole, thus further ensuring stability.
[0014] In a preferred embodiment, the top of the slider has four symmetrically arranged connecting holes.
[0015] By adopting the above technical solution, bolts can be used to securely connect the slider to the moving object, ensuring that it will not easily detach.
[0016] In a preferred embodiment, the circular groove and the abutment are positioned correspondingly, and the inner diameter of the circular groove is larger than the outer diameter of the abutment.
[0017] By adopting the above technical solution, when the slider moves to one side of the track, the abutment can be inserted into the inner wall of the circular groove, thereby squeezing the pressure sensor. This allows the pressure sensor to sense the force of the impact, enabling the user to know the position of the slider in a timely manner.
[0018] The beneficial effects of this application are:
[0019] This novel rolling linear guide pair guide structure, by inserting the abutment into the inner wall of the circular groove, allows the abutment to squeeze the pressure sensor, enabling the pressure sensor to sense the force of the impact. This allows the user to know the position of the slider in a timely manner, and the elastic force of the return spring ensures that the outer wall of the slider will not collide with the side plate, thus playing a buffering role.
[0020] This novel rolling linear guide pair guide structure, by setting inserts and through holes, allows the inserts to be synchronously positioned using bolts for fastening the rail, ensuring that they can be stably set on the inner wall of the square hole, further guaranteeing stability, simplifying the installation procedure, and improving efficiency.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0027] Reference Figure 1-4 A novel rolling linear guide pair guide structure includes a track 1, a slider 2 slidably mounted on the outer wall of the track 1, a circular hole 4 on the outer side of the slider 2, one end of a return spring 5 fixedly connected to the inner wall of the circular hole 4, and an abutment 6 fixedly connected to the other end of the return spring 5. A square hole 9 is opened on the outer side of the track 1, and an insert block 10 is adapted to be inserted into the inner wall of the square hole 9. A side plate 11 is fixedly mounted on the outer wall of the insert block 10, and a circular groove 13 is opened on the inner wall of the side plate 11. A pressure sensor 14 is installed on the inner wall of the circular groove 13.
[0028] See Figure 4 The abutment 6 is slidably connected to the inner wall of the circular hole 4. The outer diameter of the abutment 6 is matched with the inner diameter of the circular hole 4. A limiting rod 7 is fixedly installed on the inner side of the abutment 6, and the limiting rod 7 is slidably connected to the inner wall of the slider 2. This allows the abutment 6 to be retracted into the inner wall of the circular hole 4 when subjected to compressive force, thereby adjusting the return spring 5 to be in a stressed state. The limiting rod 7 can also be used to limit the movement of the abutment 6, ensuring that it does not deviate from its position.
[0029] See Figure 3 and Figure 4 A track groove 3 is provided through one side of the slider 2, and the inner wall size of the track groove 3 is adapted to the shape of the track 1, so that the slider 2 can slide stably on the outer wall of the track 1, realize position adjustment, and thus ensure the stability of the slider 2 when moving.
[0030] See Figure 2Both the bottom of the track 1 and the side plate 11 are provided with mating grooves 8, which can be used to stably install the track 1 at the installation location and ensure the stability of the connection.
[0031] See Figure 3 The top of the insert 10 is provided with a through hole 12, and the inner wall of the track 1 is provided with multiple mounting holes 15. The position of the through hole 12 corresponds to one of the mounting holes 15. The side plate 11 is provided on the outer wall of the track 1, so that the insert 10 can be synchronously positioned by means of the bolts used to fasten the track 1, ensuring that it can be stably set on the inner wall of the square hole 9, and further ensuring stability.
[0032] See Figure 3 The top of the slider 2 has four symmetrical connecting holes 16, which can be used to securely connect the slider 2 to the moving object with bolts, ensuring that it will not easily detach.
[0033] See Figure 3 and Figure 4 The circular groove 13 and the abutment 6 are positioned correspondingly. The inner diameter of the circular groove 13 is larger than the outer diameter of the abutment 6, so that when the slider 2 moves to one side of the track 1, the abutment 6 can be inserted into the inner wall of the circular groove 13, thereby squeezing the pressure sensor 14. This allows the pressure sensor 14 to sense the force of the impact, thus enabling the user to know the position of the slider 2 in a timely manner.
[0034] Working principle: First, when the slider 2 slides on the outer wall of the track 1 and moves to one side, the abutment 6 can be inserted into the inner wall of the circular groove 13. Then, the abutment 6 can squeeze the pressure sensor 14, allowing the pressure sensor 14 to sense the force of the collision. Thus, the user can know the position of the slider 2 in time. With the help of the elastic force of the return spring 5, the outer wall of the slider 2 will not collide with the side plate 11, which plays a buffering role. At the same time, the side plate 11 can resist the slider 2, ensuring that it will not easily fall off the outside of the track 1.
