DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a guide rail slider with good sealing performance, including a guide rail 1, a slider 2 is slidably installed on the inner side of the guide rail 1, a mounting block 3 is fixed on the top of the slider 2, a rubber sealing plate 4 is attached to the side wall of the slider 2, and a limiting mechanism 5 is provided on the slider 2 for facilitating the disassembly and assembly of the rubber sealing plate 4, and the limiting mechanism 5 is provided with a clamping mechanism 6.

[0024] Specifically, the limiting mechanism 5 includes a sleeve 51, a sleeve rod 52, a reset spring 54, a transmission block 53, a movable rod 57, a hinge block 56, a moving block 55, a limiting rod 58 and a limiting hole 59. The sleeve 51 is fixed to the top of the slider 2, and the sleeve rod 52 is slidably installed on the inner wall of the sleeve 51. The top of the sleeve rod 52 is fixed with a transmission block 53, and the bottom of the sleeve rod 52 is fixed with a reset spring 54. The bottom of the reset spring 54 is fixed to the inner wall of the sleeve 51. By setting the reset spring 54, the sleeve rod 52 can be reset. A moving block 55 is slidably installed on the top of the slider 2. Four moving blocks 55 are arranged on the slider 2, and two moving blocks 55 form a group, and the two groups of moving blocks 55 are symmetrically arranged with the center line of the slider 2 in the vertical direction as the symmetry axis. A hinge block 56 is fixed on the top of the moving block 55, and a movable rod 57 is hinged on the transmission block 53. The end of the movable rod 57 away from the transmission block 53 is hinged on the hinge block 56, and then when the transmission block 53 is pressed downward, the transmission block 53 will squeeze the movable rod 57, so that the movable rod 57 squeezes the two groups of moving blocks 55 away from each other, and the side wall of the moving block 55 is fixed with a limiting rod 58, and the side wall of the rubber sealing plate 4 is provided with a limiting hole 59, and the diameter of the limiting hole 59 matches the diameter of the limiting rod 58, so that the two groups of moving blocks 55 are moved away from each other, and the limiting rod 58 can be moved out of the limiting hole 59, thereby releasing the limiting fixation of the rubber sealing plate 4, and the rubber sealing plate 4 can be removed from the guide rail 1, which is convenient for replacing the rubber sealing plate 4.

[0025] Specifically, the clamping mechanism 6 includes a transmission rod 61, an extrusion spring 63, an extrusion plate 64 and a stopper 62; the transmission rod 61 runs through the moving block 55, and the moving block 55 is slidably connected to the penetration of the transmission rod 61, one end of the transmission rod 61 is fixed with a stopper 62, and the other end of the transmission rod 61 is fixed with an extrusion plate 64. By setting the extrusion plate 64, when the rubber sealing plate 4 is installed, the extrusion plate 64 can be used to squeeze the rubber sealing plate 4 and fit closely with the slider 2, thereby achieving a better sealing effect. When the rubber sealing plate 4 needs to be installed, the transmission block 53 can be pressed to make the limit rod 58 away from the sleeve 51, and the rubber sealing plate 4 can be moved to fit with the side wall of the slider 2, thereby releasing the transmission block. 53, through the reset spring 54, the sleeve rod 52 drives the transmission block 53 to move downward, and through the movable rod 57 and the moving block 55, the limiting rod 58 and the clamping mechanism 6 can be driven to squeeze, so that the arc surface at the front end of the squeezing plate 64 will contact the rubber sealing plate 4, and the squeezing plate 64 will squeeze the rubber sealing plate 4. The side wall of the stopper 62 is fixed with an squeezing spring 63, and the side of the squeezing spring 63 away from the stopper 62 is fixed on the moving block 55. Because the squeezing plate 64 is also subjected to the squeezing force, the squeezing spring 63 will be stretched. Through the squeezing spring 63, the squeezing plate 64 can always give the rubber sealing plate 4 a squeezing force, so that the sealing is better, and the rubber sealing plate 4 can be fixed by extending the limiting rod 58 into the limiting hole 59.

[0026] Working principle: When the rubber sealing plate 4 needs to be replaced, the transmission block 53 can be pressed to move downward. Through the cooperation of the movable rod 57, the hinge block 56 and the moving block 55, the limiting rod 58 can be moved out of the limiting hole 59, and the limiting of the rubber sealing plate 4 can be released. The rubber sealing plate 4 can be removed from the slider 2 for replacement.

[0027] When the rubber sealing plate 4 needs to be installed, the transmission block 53 can be pressed to make the limiting rod 58 move away from the sleeve 51, and the rubber sealing plate 4 can be moved to fit with the side wall of the slider 2, and then the transmission block 53 can be loosened, and the sleeve rod 52 can drive the transmission block 53 to move downward through the reset spring 54, and the limiting rod 58 and the clamping mechanism 6 can be driven to be squeezed through the movable rod 57 and the movable block 55, so that the arc surface at the front end of the squeezing plate 64 will contact the rubber sealing plate 4, and the squeezing plate 64 will squeeze the rubber sealing plate 4, and the limiting rod 58 can extend into the limiting hole 59 to fix the rubber sealing plate 4.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
