AI Technical Summary
Conventional guide rails can become stuck at both ends due to thermal expansion at high temperatures, affecting the stability and reliability of the sliding body running on the track.
The guide rail is equipped with sliding pillars and sliders at both ends. The sliding pillars are inserted into the elongated grooves, and the sliders are rotatably inserted into the arc-shaped grooves. The sliding grooves work together to absorb thermal expansion and prevent the guide rail from seizing up at both ends.
When the guide rail expands thermally, the sliding column and slider can move or rotate to absorb the thermal expansion, ensuring the stability, reliability and safety of the track operation.

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0029] like Figures 1 to 3 As shown, the guide rail 1 of this utility model is connected to the base 2 at both ends. A side plate 3 is fixedly installed on one side of the guide rail 1 by fasteners, and an upper cover plate 4 is fixedly installed on the top side of the guide rail 1. In use, the sliding body is installed on the side plate 3 (not shown in the figure); the function of the upper cover plate 4 is to prevent the sliding body from falling off. Figure 1 , Figure 2 As shown, a number of side support blocks 13 are spaced apart on the guide rail 1 below the side plate 3 along the length of the side plate 3. The side support blocks 13 provide support for the side plate 3, reducing the stress on the fasteners between the side plate 3 and the guide rail 1, and preventing fatigue and breakage of the fasteners due to the weight of the sliding body itself and the torque generated during movement, thus ensuring the stability, reliability and safety of the side plate 3. A number of upper support blocks 14 are spaced apart on the guide rail 1 below the upper cover plate 4 along the length of the upper cover plate 4.
[0030] like Figures 6 to 8 As shown, a sliding post 11 extends downward from the bottom surface of one end of the guide rail 1. The sliding post 11 is a cylindrical column. A slider 12 extends downward from the bottom surface of the other end of the guide rail 1. The slider 12 is an arc-shaped block. The sliding post 11 and the slider 12 can be independent components, fixedly connected to the guide rail 1, or the sliding post 11 and the slider 12 can be integrally formed on the guide rail 1.
[0031] like Figure 4 , Figure 5 , Figure 9 As shown, the base 2 has a first groove 21 and a second groove 22 corresponding to the sliding column 11 and the slider 12, respectively. The sliding column 11 is inserted into the first groove 21, and the slider 12 is inserted into the second groove 22. The first groove 21 is an elongated oval groove, the width of which matches the outer diameter of the sliding column 11, and the length of which is greater than the diameter of the sliding column 11, providing space for the sliding column 11 to move. The second groove 22 is an arc-shaped groove, the arc shape and width of which match the arc shape and width of the slider 12, and the arc length of which is greater than the arc length of the slider 12, providing space for the slider 12 to rotate. The slider 12 can rotate around the central axis of the second groove 22.
[0032] During assembly, the sliding post 11 at one end of the guide rail 1 is inserted into the first sliding groove 21 of the base 2 at one end, and the slider 12 at the other end of the guide rail 1 is inserted into the second sliding groove 22 of the base 2 at the other end. Figure 10As shown in a, in the normal temperature state, the slide column 11 is located in the middle of the first sliding groove 21, and is away from both ends of the first sliding groove 21. As shown in b, in the high temperature state, the guide rail 1 is lengthened due to thermal expansion, at this time, the slide column 11 can move along the first sliding groove 21 to absorb the thermal expansion amount. As shown in c, when the guide rail 1 is expanded, one end of the guide rail 1 can rotate and move a certain angle around the sliding block 12, and the slide column 11 at the other end can move along the first sliding groove 21 to adjust. Figure 10 Figure 10
[0033] The base 2 of the utility model cooperates with the slide column 11 and the sliding block 12 of the guide rail 1 through the sliding groove, reserves an adjusting gap for the guide rail 1, when the guide rail 1 is thermally expanded due to high temperature or the guide rail 1 is expanded, the slide column 11 and the sliding block 12 can move along the sliding groove to absorb the thermal expansion amount or the expansion amount, avoids the situation that the both ends of the guide rail 1 are expanded to death, and guarantees the stability, reliability and safety of the track operation.
[0034] The above description is the explanation of the utility model, not the limitation of the utility model, the utility model can be modified in any form without departing from the spirit of the utility model.
