According to the use requirements, the support mechanism needs to be adjusted to different positions for support. For example, an assembled linear guide with the publication number CN217502290U includes a slider, a guide rail, a first support device, a second support device and a third support device. The slider is slidably mounted on the guide rail, the first support device is fixedly mounted on the top of the slider, a moving rod is arranged on the first support device, and the moving rod is slidably arranged along the guide rail path, the second support device and the third support device are both fixedly mounted on the side of the slider, the top planes of the second support device and the third support device are flush with the top plane of the first support device, and the sides of the second support device and the third support device are both provided with a rotating rod for expanding the supporting surface, and one end of the two rotating rods is respectively connected to the second support device and the third support device. Through the above-mentioned setting, it is possible to realize the installation of assembly objects of different sizes within a certain range through a linear guide, and the number of combinations of linear guides for larger objects is less. However, the assembled linear guide still has the following disadvantages in actual use:

[0003] The supporting mechanisms of traditional linear guides are mostly fixed or connected by bolts. Therefore, when the position of the supporting mechanism needs to be adjusted, the operation is cumbersome, and frequent tightening of the bolts will cause looseness between the bolts and the screw holes, thereby affecting the subsequent positioning of the supporting mechanism. In view of the above problems, it is urgently necessary to carry out innovative designs based on the original linear guides. Utility Model Content

[0004] The purpose of the utility model is to provide a linear guide with adjustable support position, so as to solve the problem that the support mechanism of traditional linear guides proposed in the above background technology is mostly fixed or connected by bolts. Therefore, when the position of the support mechanism needs to be adjusted, the operation is cumbersome, and frequent tightening of the bolts will cause looseness between the bolts and the screw holes, thereby affecting the subsequent positioning of the support mechanism.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a linear guide rail with adjustable support position, comprising a guide rail body, a support mechanism is arranged below the guide rail body, and the support mechanism can improve the stability of the guide rail body after installation;

[0007] The limiting assembly is arranged between the movable plate and the connecting plate, and is used for locking and separating the guide rail body and the supporting mechanism. The limiting assembly extends to the inside of the movable groove, and the movable groove is symmetrically opened on both sides of the guide rail body.

[0008] Preferably, the limiting assembly includes an adjusting rod passing through both ends of the movable plate, and the adjusting rod and the movable plate are slidably connected, so that when the adjusting rod is pushed to slide in the movable plate, the connecting rod can be driven to move synchronously.

[0009] Preferably, a fixed cavity is provided in the movable plate outside the adjusting rod, and the end of the adjusting rod is connected to the inner wall of the fixed cavity through a spring, so that when the adjusting rod is not pushed, it can be driven to return to its original position through the resilience of the spring.

[0010] Preferably, the upper side of the adjusting rod is fixedly connected to one end of the connecting rod, and the connecting rod is an inverted "L"-shaped structure, and the connecting rod is slidingly connected to the movable plate and the connecting plate, and when the connecting rod moves, it drives the fixed plate and the fixed block to move synchronously.

[0011] Preferably, the other end of the connecting rod is connected to a fixing plate, and a fixing block is symmetrically provided on one side of the fixing plate close to the connecting plate, and when the fixing block is in an engaged state with the limiting hole, the stability between the supporting mechanism and the guide rail body can be ensured.

[0012] Preferably, a limiting hole is reserved in the guide rail body outside the fixed block, and the fixed block and the limiting hole are snap-fitted and distributed at equal intervals. When the fixed block is separated from the limiting hole, the supporting mechanism can be pushed to slide on the guide rail body.

The specific contents are as follows:

[0014] 1. Push the adjusting rods at both ends of the movable plate to slide on it, thereby driving the connecting rod to move synchronously. After the connecting rod moves, it drives the fixed plate to separate the fixed block from the limit hole. In this way, when the movable plate and the connecting plate are pushed, they can slide on the guide rail body to adjust the position of the support mechanism;

[0015] 2. After the adjustment is completed, release the pressure on the adjusting rod. In this way, the adjusting rod, connecting rod and fixing plate can be restored to their original positions through the resilience of the spring, and the fixing block can be driven to be stuck in the limiting hole at the corresponding position, thereby locking the position of the support mechanism after adjustment to ensure the stability of its connection with the guide rail body.
