[0018] As Figures 1 to 3As shown in the figure, a guide rail docking fixture of the present utility model includes a guide rail 1, and the guide rail 1 has two sections and is arranged in alignment. A docking device 2 for aligning the two sections of the guide rail 1 is connected to the outside of the guide rail 1. The docking device 2 includes: a fixed shell 21, a screw rod 22, a moving block 23, a slider 25, and a clamping rod 24. The fixed shell 21 is wrapped around the outside of the guide rail 1, and one end of the screw rod 22 passes through the side of the fixed shell 21 and is threadedly connected to the fixed shell 21. The screw rod 22 is rotatably connected to the moving block 23, and the moving block 23 is driven to move by the screw rod 22. A rotating handle 5 is connected to the outside of the screw rod 22, and the rotating handle 5 is rotated to make the screw rod 22 rotate. The moving block 23 is slidably connected to the upper part of the fixed shell 21. One side of the moving block 23 is fixedly connected to the slider 25, and the slider 25 is slidably connected to the upper part of the fixed shell 21. The moving block 23 drives the slider 25 to move. A ball track 3 is opened on the outside of the guide rail 1, and the ball track 3 is arc-shaped to make the clamping rod 24 slide smoothly. A clamping rod 24 is connected to the connection point of the moving block 23 and the slider 25, and the clamping rod 24 is slidably connected to the ball track 3, thereby fixing the guide rail 1. A through hole 4 is opened on the upper part of the guide rail 1, and a screw can pass through the through hole 4 to fix the guide rail 1. A chute 7 is opened on the side of the fixed shell 21, and a sliding rod 6 is slidably connected to the chute 7. The sliding rod 6 stabilizes the moving block 23 and prevents the screw rod 22 from driving the moving block 23 to rotate. The other end of the sliding rod 6 is fixedly connected to the moving block 23. There are multiple chutes 7, and sliding rods 6 are slidably connected in multiple chutes 7, and the moving block 23 is made more stable by multiple sliding rods 6.
[0019] Ball tracks 3 are opened at the four corners of the guide rail 1. There are four sliders 25, and two sliders 25 are in a group. The two groups of sliders 25 are arranged oppositely, so that the upper part of the guide rail 1 is located between the two groups of sliders 25. The two groups of sliders 25 are both slidably connected to the guide rail 1. Each of the four sliders 25 is connected to a clamping rod 24, and the four clamping rods 24 slide corresponding to the ball tracks 3.
[0020] The working process of the above solution: First, rotate the rotating handle 5 to make the screw rod 22 rotate. At this time, the screw rod 22 drives the moving block 23 and the clamping rod 24 to move in the direction of the rotating handle 5 to widen the distance between the clamping rods 24. At this time, the fixed shell 21 is placed on the outside of the guide rail 1. The slider 25 abuts against the upper part of the guide rail 1 and slides on the guide rail 1. At this time, rotate the rotating handle 5 to make the screw rod 22 drive the moving block 23 and the clamping rod 24 to move in the direction of the guide rail 1, so that the clamping rod 24 contacts the ball track 3, and the clamping rod 24 slides in the ball track 3. Push the fixed shell 21 to make the clamping rod 24 align the two sections of the guide rail 1, and then reinforce the through hole 4 with bolts.
[0021] Beneficial effects of the above solution: By means of the docking device 2, it can be quickly installed on the outside of the guide rail 1, facilitating the quick alignment of two sections of the guide rail 1; by driving the moving block 23 and the clamping rod 24 through the screw rod 22 to contact the ball tracks 3 at the four corners of the guide rail 1, at this time the clamping rod 24 fixes the guide rail 1, and the clamping rod 24 slides in the ball track 3; by contacting the four clamping rods 24 with the ball tracks 3, the stability of the guide rail 1 is increased, and due to the design of the ball tracks 3, the two sections of the guide rail 1 are butted without dislocation.
