[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0016] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0017] Example 1

[0018] See Figures 1 to 4 As shown, the guide rail structure involved in this embodiment includes a guide rail body 1 extending along a straight line, a slider body 2 slidably connected to the guide rail body 1, a working groove 3 with its opening facing the slider body on the guide rail body 1, the working groove 3 extending along the length direction of the guide rail body 1, two fixed guide wheels 4 arranged at a back-to-back interval in the working groove 3, the fixed guide wheels 4 being rotatably connected to the slider body 2, a limiting hole 5 extending along the width direction of the guide rail body on the slider body 2, a limiting block 6 slidably connected in the limiting hole 5, a movable guide wheel 7 rotatably connected to the limiting block 6 between the two fixed guide wheels, the wheel surfaces of the movable guide wheel 7 and the fixed guide wheel 4 both abutting against the groove wall of the working groove 3, one end of the limiting block 6 is provided with an elastic element 8 provided in the limiting hole, and the other end is provided with an adjusting screw 9 with its end abutting against the limiting block, the adjusting screw 9 being threadedly connected to the slider body 2.

[0019] Furthermore, the movable guide wheel 7 and the fixed guide wheel 4 are provided with annular grooves 10 with a semi-circular cross section and a closed ring shape. A circular guide rail 11 connected to the guide rail body is embedded in the annular groove 10. The circular guide rail 11 extends along the length direction of the guide rail body 1.

[0020] Furthermore, the movable guide wheel 7 is equidistant from any fixed guide wheel 4.

[0021] Furthermore, both ends of the working groove 3 are connected to the outside world.

[0022] In this embodiment, the adjusting screw 9 is not tightened in the initial state, and the movable guide wheel 7 is close to the fixed guide wheel 4. At this time, the distance between the movable guide wheel 7 and the fixed guide wheel 4 is small, so the slider body 2 can be quickly pre-installed on the guide rail body 1 until the fixed guide wheel 4 and the movable guide wheel 7 are embedded in the working groove 3. Then, by tightening the adjusting screw 9, the limiting block 6 is moved outward, and the elastic element 8 is compressed, so that the distance between the movable guide wheel 7 and the fixed guide wheel 4 increases until they are tensioned in the working groove 3. Finally, the circular guide rail 11 on one side of the groove is embedded in the annular groove 10 of the fixed guide wheel 4, and the circular guide rail 11 on the other side is embedded in the annular groove 10 of the movable guide wheel 7, so as to realize the sliding function of the slider body 2 relative to the guide rail body 1.

[0023] The guide rail structure involved in this utility model has the characteristics of simple structure and convenient assembly. Furthermore, the damping effect of the relative sliding between the slider and the guide rail is adjustable, making adjustment convenient. The overall function is complete and highly practical.
