In prior art, most guide rails are generally exposed to the outside environment for a long time when not in use, in this case, the dust and impurities in the environment will accumulate on the guide rail, since the relative motion between sliding block and guide rail is based on external force, and the friction between the two will hinder the relative motion, and the accumulation of dust and impurities will increase the roughness of the contact surface of guide rail and sliding block, thereby increasing the friction, which greatly affects the movement of sliding block and is not conducive to practical application.

DETAILED DESCRIPTION
[0018] The specific implementation of the utility model will be further described below in combination with the drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.
[0019] Please see Figures 1-3 This utility model provides a technical solution: a linear guide rail with a dustproof structure, including a guide rail body 1 connected with a slider 2, a dustproof structure on the outside of the guide rail body 1, the dustproof structure including a pair of dustproof covers 3 that can be spliced, mounting plates 4 detachably connected to the bottom ends of the guide rail body 1, the two ends of the guide rail body 1 being connected to the mounting plates 4 by fasteners, positioning plates 5 respectively located on both sides of the guide rail body 1 fixed on the mounting plates 4, the positioning plates 5 are used to quickly position the guide rail body 1 so as to connect with the mounting plates 3, and the ends of the dustproof covers 3 are movably connected to the mounting plates 4 respectively;
[0020] Furthermore, the mounting plate 4 has movable plates 6 at both ends that move along its length. The dust cover 3 is connected to the movable plates 6 at its end via a pivot 7. The pivot 7 can be a damping pivot, which makes it easy to stop at different arbitrary angles.
[0021] Furthermore, the bottom of the movable plate 6 is fixed with an assembly frame 12, and a steel ball 13 is installed inside the assembly frame 12. The top of the mounting plate 4 is provided with a sliding groove 14 that matches the steel ball 13. By utilizing the cooperation between the steel ball 13 and the sliding groove 14, the friction between the movable plate 6 and the mounting plate 4 is reduced, and the smoothness of the movable plate 6 is improved.
[0022] Furthermore, support plates 8 are fixed at both ends of the mounting plate 4, and guide rods 9 are fixed between the support plates 8 and are movably inserted through the movable plate 6. The guide rods 9 are used to restrict the movement trajectory of the movable plate 6, prevent the movable plate 6 from deviating from the normal movement trajectory, and improve stability.
[0023] Furthermore, a support block 10 is fixed to the side of the movable plate 6. When the dust cover 3 is in the assembled state, the support block 10 provides support to the end of the dust cover 3 away from the rotating shaft 7, thereby improving the stability of the dust cover 3. Pads 11 are fixed to both ends of the mounting plate 4. When the dust cover 3 is in the separated state, the pads 11 provide support to the dust cover 3, thereby making it stably placed above the mounting plate 4.
[0024] Specifically, by setting up a dust cover 3, a mounting plate 4, a movable plate 6, and a rotating shaft 7, when the guide rail body 1 is not needed, the slider 2 is separated from the linear guide rail 1. Then, by flipping the dust cover 3 so that its inner side faces down, and by adjusting the distance between adjacent movable plates 6, the dust cover 3 is moved to make it fully fit together, preventing dust and impurities from falling onto the guide rail body 1. Compared with existing technologies, this not only provides a dustproof effect for the guide rail body 1, but also allows sufficient space for the slider to cooperate with the guide rail body 1 by flipping the dust cover 3 and adjusting the position of the movable plate 6, avoiding affecting the operation of the guide rail body 1 and the slider 2, making it convenient to use.
[0025] Furthermore, the bottom of the outer wall of the dust cover 3 is set as a slope, and the bottom of the dust cover 3 is higher on the side closer to the guide rail body 1; when adjacent dust covers 3 are spliced together, the spliced dust cover 3 forms a symmetrical slope structure, presenting a state of high in the middle and low on both sides, so that dust and impurities slide down the dust cover 3 to both sides under the action of gravity, reducing the accumulation of dust on the dust cover 3.
[0026] Furthermore, the mating surfaces of adjacent dust covers 3 are provided with recessed grooves 15, and magnetic sheets 16 with opposite magnetic properties are respectively installed in the recessed grooves 15. The thickness of the magnetic sheets 16 is the same as the depth of the recessed grooves 15.
[0027] Specifically, by setting the embedded groove 15 and the magnetic sheet 16, the magnetic sheet 16 with opposite magnetism makes the adjacent dust covers 3 attract and fit together, providing sufficient protection for the guide rail body 1. In conjunction with the embedded groove 15, the magnetic sheet 16 does not protrude from the mating surface of the adjacent dust covers 3, preventing obvious gaps and improving the dustproof effect.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
