[0021] like Figure 1 and Figure 3 As shown, one end of the moving rod 9 is connected to the moving plate 4, a roller 11 is provided under the moving plate 4, a rolling groove 10 is provided in the bottom plate 1, the roller 11 is slidably connected in the rolling groove 10, a T-slot 5 is provided in the rail plate 1 2, the auxiliary plate 12 is threadedly connected to the outside of the threaded rod 2 602, the motor 603 is fixedly connected in the moving plate 4, the gear 1 604 is rotatably connected in the moving plate 4, the threaded rod 1 601 is connected to the threaded rod 2 602 through the anti-slip belt 606, the threaded rod 1 601 is rotatably connected to the moving plate 4, the threaded rod 2 602 is rotatably connected to the moving plate 4, the gear 1 604 is meshed with the gear 2 605, and the output shaft of the motor 603 is connected to the gear 1 604.

[0022] By setting the rolling groove 10, roller 11 and anti-slip belt 606, when the telescopic device 8 and the moving rod 9 apply thrust or tension to the moving plate 4, the roller 11 under the moving plate 4 will roll in the rolling groove 10, so that the rolling groove 10 and the roller 11 play a certain guiding role in the movement of the moving plate 4, ensuring the stability of the moving plate 4 during movement. When the threaded rod 2 602 rotates, the threaded rod 1 601 will rotate synchronously with the threaded rod 2 602 through the anti-slip belt 606, so that the auxiliary plate 12 can move evenly on the surface of the threaded rod 1 601 and the threaded rod 2 602, avoiding the position displacement of the auxiliary plate 12 during movement.

[0023] like Figure 4 As shown, a T-shaped block 14 is fixedly connected to one side of the track plate 2 13, and the T-shaped block 14 is clamped in the track plate 1 2. The clamping structure 7 includes a fixing rod 701 and a limiting column 702. The fixing rod 701 is fixedly connected to the front of the track plate 2 13, and the limiting column 702 is fixedly connected to the front of the track plate 1 2.

After the card plate 703 rotates, it will overlap with the limiting column 702, so that the fixing rod 701 plays a certain supporting role in the rotation of the card plate 703, avoiding the limiting column 702 from falling off when it is flipped.

[0025] The utility model provides an adjustable track for a linear guide rail, and the specific working principle is as follows:

[0026] When the linear guide rail adjusts the length of the upper rail plate 2 according to actual conditions, after the telescopic device 8 applies a thrust to the moving rod 9, the moving plate 4 will roll in the rolling groove 10 through the roller 11. When the moving plate 4 moves to the appropriate position, the motor 603 drives the gear 1 604 to rotate. Since the gear 1 604 is meshed with the gear 2 605, the threaded rod 2 602 will rotate synchronously with the gear 1 604 through the gear 2 605, and the threaded rod 1 601 will rotate synchronously with the threaded rod 2 602 through the anti-slip belt 606. The auxiliary plate 12 will move on the surface of the threaded rod 1 601 and the threaded rod 2 602, and the auxiliary plate 12 will drive the rail plate 2 13 to engage with the rail plate 1 2.

[0027] When the track plate 2 13 moves upward, the T-block 14 on the side of the track plate 2 13 will be clamped into the track plate 1 2. When the track plate 2 13 is completely fitted with the track plate 1 2, it will drive the clamping plate 703 to rotate around the fixed rod 701. After rotation, the clamping plate 703 will overlap the surface of the limiting column 702, and the clamping plate 703 will be threadedly connected to the limiting column 702 through the bolt 704.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
