[0031] 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.
[0032] Reference Figure 1 and Figure 2 The present invention provides an embodiment of an anti-collision linear slider, comprising a guide rail 1, a slider 2 slidably connected to the top of the guide rail 1, an anti-collision assembly 3 slidably connected to the end of the guide rail 1, a limit plate 4 provided at the end of the guide rail 1, and a quick-release assembly 5 installed inside the limit plate 4; the anti-collision assembly 3 includes a connecting plate 6 slidably connected to the outside of the guide rail 1 and used to connect other components. A buffer pad 7 is fixedly connected to the side of the connecting plate 6, and a slide bar 8 is fixedly connected to the other side of the connecting plate 6. A spring 9 is sleeved on the outer periphery of the slide bar 8. When the slider 2 slides to the end of the guide rail 1, it contacts the buffer pad 7 and, through the cooperation of the spring 9 and the slide bar 8, relieves the force generated by the sliding of the slider 2. The slide bar 8 is slidably connected to the inside of the limit plate 4, and a spring 9 is provided at a position where the connecting plate 6 and the limit plate 4 face each other. The spring 9 is provided between the connecting plate 6 and the limit plate 4 to buffer the force generated by the movement of the slider 2 and protect the slider 2 and the limit plate 4.
[0033] Reference Figure 1-Figure 4The quick-release assembly 5 includes a fixed block 10, which is fixedly connected to the inside of the limit plate 4. The bottom of the fixed block 10 is fixedly connected to a fixed rod 11, and the limit plate 4 is used to fix the quick-release assembly 5. Two slides 12 are slidably connected to the outside of the fixed rod 11, and the sides of the two slides 12 are fixedly connected to a clamping block 13. When the slides 12 move, the clamping block 13 is controlled to move. A spring 2 14 is sleeved on the outer periphery of the fixed rod 11. The spring 2 14 is set at the position where the two slides 12 face each other. The slides 12 are squeezed by the spring 2 14, giving pressure to the clamping block 13 to move upward. A card slot 15 is provided inside the guide rail 1, and the clamping block 13 and the card slot 15 are clamped with each other. The position of the limit plate 4 is fixed by the cooperation of the clamping block 13 and the card slot 15.
[0034] Reference Figure 1 and Figure 2 The limit plate 4 has an internal slot 16, and the two slides 12 are slidably connected to the internal slot 16. The provision of the slot 16 increases the space for the slides 12 to move. Buffer blocks 18 are fixedly connected to both sides of the slider 2. The buffer blocks 18 are installed on the slider 2 to further reduce the force generated when the slider 2 moves. The buffer pad 7 and the buffer block 18 are both made of rubber material. The use of rubber material ensures the buffering effect of the buffer pad 7 and the buffer block 18. The guide rail 1 has an internal mounting hole 17 to facilitate the fixed installation of the guide rail 1 on the equipment.
[0035] Working principle: The slider 2 performs low-friction linear motion on the guide rail 1. When the slider 2 moves to the end of the guide rail 1, the buffer block 18 on the side of the slider 2 contacts the buffer pad 7, squeezing the spring 1 9, and removing the pressure generated by the linear motion of the slider 2, ensuring the safety of the slider 2 and the limit plate 4 and avoiding damage to them. The slide plate 12 is pressed inward to make it slide on the fixed rod 11 to squeeze the spring 2 14, and the block 13 is disengaged from the slot 15 of the guide rail 1, and the limit plate 4 is quickly disassembled, which is convenient for maintenance and replacement of components of the anti-collision component 3, especially the spring 1 9 that is prone to fatigue damage, to avoid damaged components affecting the normal operation of the anti-collision component 3 and ensure the stability of equipment operation.
