[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3The utility model provides a technical solution of a guide rail mechanism: it includes a guide rail body 1, a serrated plate 4 and a card plate 10. A guide groove 2 is provided on the top surface of the guide rail body 1. The inner walls on both sides of the top end of the guide groove 2 are fixedly installed with the serrated plates 4 by welding. A slider 5 is slidingly provided inside the guide groove 2. Notches 8 are provided on both sides of the bottom end of the slider 5. A retractable card plate 10 is slidingly provided on the inner top wall of the notch 8. A lifting inclined plate 9 is slidingly provided inside the slider 5. The top of the card plate 10 passes through the outer shell of the slider 5 and extends to the interior of the slider 5 and is fixedly connected to the bottom sides of the lifting inclined plate 9 by welding. A translation inclined plate 11 is provided on the top of the lifting inclined plate 9, and the translation inclined plate 11 is in sliding contact with the lifting inclined plate 9.

[0021] Specifically, a small spring 14 is provided at the bottom middle end of the lifting inclined plate 9 , and two ends of the small spring 14 are fixedly connected to the bottom middle end of the lifting inclined plate 9 and the inner bottom surface of the slider 5 respectively.

[0022] Specifically, a large spring 13 is provided at one end of the translation inclined plate 11 , and two ends of the large spring 13 are fixedly connected to one end of the translation inclined plate 11 and the inner wall of the slider 5 , respectively.

[0023] Specifically, bumps 6 are provided on both sides of the bottom end of the slider 5 , and the bumps 6 are fixedly connected to the slider 5 by welding.

[0024] Specifically, the inner walls on both sides of the bottom end of the guide groove 2 are provided with limiting grooves 3 , and the protrusions 6 extend into the limiting grooves 3 and are slidably connected with the inner walls thereof.

[0025] Specifically, rollers 7 are provided on the inner sides of the top and bottom of the protrusion 6 , and the rollers 7 on the top and bottom of the protrusion 6 are in close contact with the top wall and bottom surface of the limiting groove 3 respectively.

[0026] Specifically, one end of the translation inclined plate 11 passes through the housing of the slider 5 and extends to the outside and is slidably connected thereto. The push plate 12 is fixedly mounted on the end of the translation inclined plate 11 extending to the outside.

[0027] In this embodiment, in a static state, the card plate 10 at the bottom of the lifting inclined plate 9 extends to the inside of the notch 8 and forms a card connection with the serrated plate 4. When the slider 5 needs to be moved, the push plate 12 is pushed to drive the translation inclined plate 11 to translate, and the large spring 13 is compressed, so that the inclined surface at the bottom of the translation inclined plate 11 and the inclined surface at the top of the lifting inclined plate 9 are misaligned, and under the action of the small spring 14, the lifting inclined plate 9 is lifted up, thereby contracting the card plate 10 toward the inside of the slider 5 until it is out of the card connection with the serrated plate 4. At this time, the slider 5 can be pushed to adjust its position. After reaching the appropriate position, release the push plate 12, and under the action of the large spring 13, push the translation inclined plate 11 to reset. Since the elastic force of the large spring 13 is much greater than the elastic force of the small spring 14, when the translation inclined plate 11 is reset, it squeezes the lifting inclined plate 9, thereby causing the lifting inclined plate 9 to move downward, extending the card plate 10 to the inside of the notch 8, and forming a clamping state with the serrated plate 4, thereby completing the positioning of the slider 5. In this process, no operation is required. After releasing the push plate 12, the card plate 10 will automatically form a clamping state with the serrated plate 4, thereby realizing the automatic positioning function of the slider 5.

[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.
