Detailed implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Referring to the attached drawings of the specification Figures 1-4 , a quick disassembly device for a filter element of a road roller of the present invention includes a connecting block 1. For details, see Figure 3 , one side of the connecting block 1 is rotatably connected to a kit 2. A clamping block 3 is slidably connected inside the kit 2. A threaded rod 4 is threadedly connected inside the clamping block 3. The threaded rod 4 is rotatably connected inside the kit 2. The end of the threaded rod 4 is fixedly connected to a knob 5. A compression spring 6 is fixedly installed inside the kit 2. One end of the compression spring 6 is fixedly installed with a clamping block 7. The clamping block 7 is slidably connected inside the kit 2. A card slot 8 is opened inside the connecting block 1. The clamping block 7 is inserted into the card slot 8;

[0022] A connecting rod 9 is rotatably connected to the outer wall of the connecting block 1. For details, see Figure 1 , one end of the connecting rod 9 away from the connecting block 1 is rotatably connected to a connecting square rod 10. Through the setting that a certain pressure is required for the rotational connection between the connecting block 1, the connecting rod 9, and the connecting square rod 10, the connecting block 1, the connecting rod 9, and the connecting square rod 10 will not deform without external force. For details, see Figure 4 , a convex groove 11 is opened inside the connecting square rod 10. A limiting rod 12 is fixedly connected inside the convex groove 11. A spring piece 13 is sleeved on the outer wall of the limiting rod 12. The spring piece 13 is arranged inside the convex groove 11. A clamping plate 14 is arranged on the top of the spring piece 13. The clamping plate 14 is slidably connected inside the convex groove 11. A sleeve 15 is sleeved on the outer wall of the connecting square rod 10. The clamping plate 14 is inserted into the sleeve 15. A pressing block 16 is slidably connected inside the sleeve 15. The pressing block 16 is arranged on one side of the clamping plate 14. Anti-slip patterns 17 are opened on the outer wall of the sleeve 15. Through the setting of the anti-slip patterns 17, the firmness of the staff holding the sleeve 15 is improved.

[0023] It should be noted that when the staff needs to disassemble the filter element of the road roller, first put the kit 2 on the bolt that fixes the filter element on the road roller, and then rotate the knob 5, so that the knob 5 drives the threaded rod 4 to rotate, and then the threaded rod 4 pushes the clamping block 3 to slide along the inside of the kit 2 until it stops after fitting the bolt inside the kit 2. At this time, the size of the space formed by the kit 2 and the threaded rod 4 is adapted to the size of the bolt, so as to achieve the effect of adjusting according to the size of the bolt that fixes the filter element, which is convenient for the staff to disassemble the bolt without the staff replacing bolts of appropriate size for disassembly, reducing the tools that the staff needs to carry and facilitating the staff to use;

[0024] Furthermore, after adjusting the disassembly device according to the size of the bolt, the staff can adjust the rotation angles of the connecting rod 9 and the connecting square rod 10 according to the components inside the road roller, so that the overall shape of the disassembly device changes, and then the disassembly device better adapts to the space inside the road roller, so that when the disassembly device disassembles the bolt, it will not touch the components inside the road roller, facilitating the staff to use;

[0025] Furthermore, through the ratchet mechanism set by the pressure spring 6, the clamping block 7 and the card slot 8, when the staff uses the disassembly device to disassemble the bolt that fixes the filter element, the card slot 8 inside the connecting block 1 can drive the kit 2 to rotate unidirectionally through the clamping block 7 (when rotating the clamping block 7 in the other direction, the clamping block 7 will be squeezed into the inside of the kit 2 by the card slot 8, so that the kit 2 stays in place and will not rotate), which is convenient for the staff to quickly disassemble the bolt, preventing insufficient space inside the road roller from affecting the staff's disassembly of the bolt and further affecting the quick disassembly of the filter element;

[0026] Furthermore, when the staff needs to adjust the overall length of the disassembly device, the staff can press the pressing block 16, so that the pressing block 16 squeezes the clamping plate 14 to move along the inside of the convex groove 11 and stop clamping the sleeve 15. At this time, the clamping plate 14 stops limiting the connecting square rod 10 and the sleeve 15, and the sleeve 15 can slide along the outer wall of the connecting square rod 10, so that the connecting square rod 10 and the sleeve 15 can be elongated, and then the overall length of the disassembly device is changed, which is convenient for the staff to adjust the disassembly device according to the size of the space inside the road roller, so as to facilitate the quick disassembly of the bolt that fixes the filter element and improve the staff's use experience. It should be noted that when the clamping plate 14 slides down along the inside of the convex groove 11, it will squeeze the spring piece 13 to deform. After the staff adjusts the overall length of the convex groove 11 and the sleeve 15, control to stop squeezing the pressing block 16, so that the spring piece 13 can reset and push the clamping plate 14 to reset, and then the clamping plate 14 re-inserts into the inside of the sleeve 15 to limit the connecting square rod 10 and the sleeve 15 and push the pressing block 16 to move and reset, waiting for the next operation.
