By adjusting the positions of the bolts on the first through holes at different heights, the height of the fixing plate 3 can be adjusted so that the fixing plate 3 can be located between the two slide rails 1.

[0026] The locking mechanism 4 is arranged on the fixed plate 3, and the locking mechanism 4 is used for locking and fastening the transport vehicle 2 to the slide rail 1 through the fixed plate 3 and the mounting mechanism 5 to prevent the transport vehicle 2 from sliding or moving on the slide rail 1.

The double-headed cam 42 can squeeze and push the two sliding blocks 46 to move in opposite directions through the semicircular surface during the rotation process, so as to tighten and fix the friction block 45 on the slide rail 1 through the connecting rod 44, thereby achieving the purpose of locking and fastening the fixing plate 3 on the slide rail 1, and then achieving the purpose of locking and fastening the transport vehicle 2 on the slide rail 1 through the installation mechanism 5, preventing the transport vehicle 2 from sliding or moving when parked on the slide rail 1, avoiding the risk of accidents, and at the same time enabling the transport vehicle 2 to park on the slide rail 1 with a certain slope, making the loading and unloading operations of the transport vehicle 2 more convenient and quick, and improving the overall work efficiency.

[0027] The fixed plate 3 is provided with a driving mechanism 6. The top end of the first rotating shaft 41 passes through the fixed plate 3 and is in transmission connection with the driving mechanism 6. The driving mechanism 6 is used to drive the first rotating shaft 41 to rotate. Specifically, a vertical plate 61 extending upward is fixedly provided on the top of the fixed plate 3. A second rotating shaft 62 is rotatably passed through the vertical plate 61. The rear end of the second rotating shaft 62 passes through the vertical plate 61 and is fixed with a rocker 65. The rocker 65 has a long length and is a metal rod with a certain toughness. By manually pulling the top end of the rocker 65 , and can use the principle of leverage to drive the second rotating shaft 62 to rotate with a lighter force; the front end of the second rotating shaft 62 passes through the vertical plate 61 and is fixed with a first bevel helical gear 63, and the top end of the first rotating shaft 41 passes through the fixed plate 3 and is fixed with a second bevel helical gear 64, the first bevel helical gear 63 is meshed with the second bevel helical gear 64, and the size of the first bevel helical gear 63 is larger than the second bevel helical gear 64, when the first bevel helical gear 63 rotates, it can drive the second bevel helical gear 64 to rotate a greater angle.

[0028] By manually turning the rocker 65 to rotate leftward, the rocker 65 drives the second rotating shaft 62 to rotate, and drives the first rotating shaft 41 and the double-headed cam 42 to rotate through the first conical bevel gear 63 and the second conical bevel gear 64, so that the double-headed cam 42 squeezes and pushes the two sliding blocks 46 to move in opposite directions. During the movement of the sliding blocks 46, the friction blocks 45 are pushed and fixed on the slide rail 1 through the connecting rod 44, achieving the purpose of locking and fastening the fixing plate 3 on the slide rail 1. Furthermore, through the installation mechanism 5, the purpose of locking and fastening the transport vehicle 2 on the slide rail 1 is achieved, preventing the transport vehicle 2 from sliding or moving when parked on the slide rail 1, avoiding the risk of accidents. At the same time, the transport vehicle 2 can be docked on the slide rail 1 with a certain slope, making the loading and unloading operation of the transport vehicle 2 more convenient and fast, and improving the overall work efficiency.

[0029] A fixing mechanism 7 is provided on the fixing plate 3, and the rocker 65 is arranged on the fixing mechanism 7. The fixing mechanism 7 is used to fix the rocker 65, so that after the rocker 65 drives the locking mechanism 4 to lock and fasten the transport vehicle 2 on the slide rail 1, the reverse rotation of the rocker 65 is prevented. Specifically, the fixing mechanism 7 includes two support rods 71 fixedly arranged on the fixing plate 3 and extending upward. An arc-shaped plate 72 is fixedly arranged at the top of the support rod 71. The arc-shaped plate 72 is arranged in an arc with the second rotating shaft 62 as the center. A plurality of first jacks 73 that are spaced at intervals along its extending direction and penetrate through from front to back are opened at the left end of the arc-shaped plate 72; a second jack that can correspond to any one of the first jacks 73 from front to back is opened on the rocker 65. A positioning pin 74 that can slide back and forth is inserted into the second jack. The front end of the positioning pin 74 can penetrate out of the second jack and be inserted into any one of the first jacks 73 to fix the rocker 65. And because the rocker 65 is a metal rod with a certain toughness, the rocker 65 can undergo slight deformation, facilitating the positioning pin 74 at the top of the rocker 65 to be inserted into the first jack 73.

[0030] Two supports 8 are arranged at the bottom of the fixing plate 3 at intervals from left to right. A spring 9 is arranged between the supports 8 on the same side and the friction block 45. The spring 9 is used to apply a pulling force to the friction block 45, so that after the rocker 65 is disengaged from the fixation of the fixing mechanism 7, the spring 9 can drive the friction block 45 to move towards the middle of the fixing plate 3 for resetting.

[0031] On the top of the fixed plate 3, two plate members 10 are fixedly arranged at intervals left and right. At the rear side of the plate member 10, two U-shaped cards 11 are fixedly arranged at intervals left and right. A square rod 12 capable of sliding left and right is commonly inserted into the two U-shaped cards 11 on the same plate member 10. The bottom end of the mounting plate 51 is fixedly arranged on the square rod 12, and there are gaps between the left and right ends of the mounting plate 51 and the U-shaped cards 11, so that the mounting plate 51 can slide left and right within a small range through the square rod 12. When the distances between the friction blocks 45 on the left and right and their adjacent slide rails 1 are different, after one of the friction blocks 45 contacts the slide rail 1, it pushes the fixed plate 3 to move left and right through the reaction force, so that the two friction blocks 45 can simultaneously press and fix on their adjacent slide rails 1, preventing one of the friction blocks 45 from not being able to contact the slide rail 1, resulting in a poor locking effect, thereby avoiding the displacement or sliding of the transport vehicle 2.

[0032] Working principle: When it is necessary to dock and lock the transport vehicle 2 on the slide rail 1, manually turn the rocker 65 to rotate left. The rocker 65 drives the second rotating shaft 62 to rotate, and drives the first rotating shaft 41 and the double-headed cam 42 to rotate through the first conical bevel gear 63 and the second conical bevel gear 64, so that the double-headed cam 42 squeezes and pushes the two sliding blocks 46 to move in opposite directions. When the sliding blocks 46 move, they push the friction blocks 45 to press and fix on the slide rail 1 through the connecting rod 44, and then lock and fasten the fixed plate 3 on the slide rail 1, and then lock and fasten the transport vehicle 2 on the slide rail 1 through the installation mechanism 5; then insert the positioning pin 74 into the first jack 73 to fix the rocker 65.

[0033] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
