[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-5As shown, this utility model is a track plate connection structure, including a track plate 1, and further including: multiple sets of protrusions 2 fixedly connected to the outer side of the track plate 1, a locking mechanism provided inside the protrusions 2, an installation hole 3 opened inside the protrusions 2, an installation shaft 4 slidably connected inside the installation hole 3, a snap-fit ​​block 5 fixedly connected to one side of the installation shaft 4, and the snap-fit ​​block 5 is hexagonal and snaps into the inside of the protrusions 2. By the snap-fit ​​block 5 cooperating with the protrusions 2, the installation shaft 4 is initially fixed. The installation shaft 4 is fixedly connected to the snap-fit ​​block 5, and at the same time, the installation shaft 4 is slidably connected inside the installation hole 3. Thus, the connection between the protrusions 2 and the track plate 1 is achieved by the cooperation between the installation shaft 4 and the installation hole 3.

[0023] The locking mechanism includes a threaded cover 6, an annular block 7, a second locking block 8, and a clamping block 9. The threaded cover 6 is threadedly connected to the surface of the protrusion 2. The annular block 7 is rotatably installed inside the threaded cover 6. The second locking block 8 is fixedly connected to the inside of the annular block 7. Two sets of clamping blocks 9 are symmetrically and slidably locked inside the protrusion 2. Two sets of third locking blocks 10 are symmetrically and fixedly connected to the outer side of the second locking block 8, and the third locking blocks 10 are slidably locked inside the protrusion 2. Two sets of locking grooves 11 are symmetrically opened on the surface of the mounting shaft 4, and the locking grooves 11 can contact the surface of the clamping block 9. The cover 6 moves along the surface of the protrusion 2, while the threaded cover 6 is rotatably connected to the annular block 7, and the annular block 7 is fixedly connected to the snap-fit ​​block 8. At the same time, a T-shaped snap-fit ​​block is provided on the inner side of the snap-fit ​​block 8, and a snap-fit ​​block 3 10 is fixedly connected to the outer side of the snap-fit ​​block 8 to further guide the snap-fit ​​block 8. Meanwhile, the clamping block 9 slides and snaps onto the surface of the T-shaped snap-fit ​​block provided on the inner side of the snap-fit ​​block 8, and the clamping block 9 is slidably connected to the protrusion 2. Then, the threaded cover 6 drives the clamping block 9 to move. At the same time, a snap-fit ​​groove 11 is opened on the surface of the mounting shaft 4, and the clamping block 9 is engaged with the snap-fit ​​groove 11 to fix the mounting shaft 4.

[0024] In use, by rotating the threaded cover 6 and moving it along the surface of the protrusion 2, the annular block 7 and the second snap-fit ​​block 8 are moved. At the same time, the snap-fit ​​block 3 10 further guides the movement, and the movement of the second snap-fit ​​block 8 causes the clamping block 9 to engage inside the snap-fit ​​groove 11, enabling quick assembly and disassembly of the mounting shaft 4, which facilitates subsequent quick replacement and increases the efficiency of the workers in replacing the shaft.

[0025] The protrusion 2 has a groove 12 inside, and two sets of sliding blocks 13 are symmetrically slidably connected inside the groove 12. A guide post 14 is fixedly connected inside the sliding block 13 and passes through the protrusion 2. A sliding plate 15 is symmetrically fixedly connected to the outside of the guide post 14. A spring 16 is provided on the surface of the guide post 14 and is located inside the protrusion 2. The guide post 14 is moved by the sliding plate 15. The guide post 14 is fixedly connected to the sliding block 13. At the same time, the sliding block 13 is slidably connected inside the groove 12. The guide post 14 is provided with a spring 16 on the surface. The sliding block 13 compresses the spring 16 to buffer the movement of the sliding plate 15.

[0026] In use, the sliding plate 15 drives the guide column 14 to move, and at the same time drives the sliding block 13 along the inside of the slide groove 12, thereby squeezing the spring 16, so as to buffer the collision between the protrusions 2 and further increase the service life of the track plate 1.

[0027] Working principle: First, the mounting shaft 4 is slid into the mounting hole 3 inside the protrusion 2. Then, by rotating the threaded cover 6, it moves along the inside of the annular block 7, causing the second snap-fit ​​block 8 to slide along the inside of the protrusion 2. At the same time, the snap-fit ​​block 3 10 provides guidance, thereby causing the clamping block 9 to engage with the snap-fit ​​groove 11, thus realizing the installation between the track plates 1. In use, the track plates 1 push the sliding plate 15 and the guide post 14 to move, thereby causing the sliding block 13 to slide along the inside of the slide groove 12, compressing the spring 16, thereby buffering between the protrusions 2 and increasing the service life of the track plates 1.

[0028] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
