Description

Technical Field

[0001] This utility model relates to the field of treadmill board technology, specifically to a noise-reducing and shock-absorbing treadmill board. Background Technology

[0002] Treadmills are common fitness equipment in homes and gyms, and are among the simplest home fitness equipment available today, making them an excellent choice for home workouts. A typical treadmill includes a base, a running belt mounted on the base, a running board to support the running belt, a drive mechanism to rotate the running belt, and handrails. The running board is the supporting component of the treadmill, fixed to the base. When people use the treadmill for exercise, their feet step on the running belt, which is supported by the running board. The running belt slides on the running board at a set speed. Existing running boards have several shock-absorbing grooves when installing shock-absorbing components, which reduces the overall integrity of the running board and thus lowers its overall structural strength.

[0003] To address the aforementioned technical issues, Chinese Patent No. CN220757897U discloses a noise-reducing and shock-absorbing treadmill board, which includes a running board body. The running board body consists of a base plate, a buffer plate, and a wear-resistant plate arranged sequentially from bottom to top. The top surface of the wear-resistant plate is provided with multiple shock-absorbing grooves spaced apart along the width direction. The wear-resistant plate is provided with reinforcing plates arranged along the length direction within the shock-absorbing grooves. The reinforcing plates are detachably installed in the shock-absorbing grooves.

[0004] Although the existing technical solution described above uses reinforcing plates to improve the overall structural strength of the treadmill plate, its multiple mounting bases are fixed and disassembled by rotating bolts one by one, and the mounting sleeve is welded to one end of the wear-resistant plate. This makes it cumbersome and inconvenient for workers to disassemble, repair, or replace the shock-absorbing components, thus affecting the efficiency of workers in disassembling, repairing, and replacing the shock-absorbing components.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A noise-reducing and shock-absorbing treadmill board includes a base plate 1, a buffer plate 2 installed on one side of the base plate 1, and a wear-resistant plate 3 snapped onto the top of the buffer plate 2 via a positioning and shock-absorbing mechanism. The positioning and shock-absorbing mechanism includes a first positioning component, a shock-absorbing component, and a second positioning component. The first positioning component is used to snap the shock-absorbing component onto the buffer plate 2, and the second positioning component is used to snap the other end of the shock-absorbing component onto the wear-resistant plate 3. The shock-absorbing component is used to mitigate the vibration generated by the treadmill board. The shock-absorbing component includes two sets of connecting plates 4, with mounting posts 5 installed at both ends of the top of the connecting plates 4. A mounting sleeve 6 is fitted onto the outer side of the mounting post 5, and the inner side of the mounting sleeve 6... A noise-reducing plate 7 is installed on one side, and a buffer spring 8 is installed between the other end of the noise-reducing plate 7 and one end of the mounting column 5. When in use, the shock-absorbing component can be snapped to the buffer plate 2 by the first positioning component, and the other end of the shock-absorbing component can be snapped to the wear-resistant plate 3 by the second positioning component. The shock-absorbing component relieves the vibration generated by the treadmill plate. The structure is simple and easy to operate. The shock-absorbing component can be installed or removed from the treadmill plate by snapping and pressing. There is no need for personnel to twist the bolts one by one or cut the weld joints to repair and replace the worn and aged shock-absorbing components, which improves the efficiency of disassembly, repair and replacement.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the first positioning component includes plug-in blocks 9 installed at both ends of the bottom of the connecting plate 4. A plug-in groove is provided on one side of the buffer plate 2, which is slidably connected to the plug-in blocks 9. A compression groove is provided on one side of the plug-in groove inside the connecting plate 4. A compression block 10 is slidably connected inside the compression groove. Compression springs are installed between both ends of one side of the compression block 10 and the inner wall of the compression groove. A sliding rod 11 is installed on one side of the compression block 10 between the two sets of compression springs. The sliding rod 11 is slidably connected to the buffer plate 2. A sliding plate 12 is installed at one end of the sliding rod 11, and the sliding plate 12 is slidably connected to the buffer plate 2. The sliding plate 12 has a latching groove on one side and a positioning hole extending into the insertion block 9 on one side of the inner wall of the extrusion groove. The other side of the extrusion block 10 is equipped with a positioning post 13 that engages with the positioning hole. First, the latching groove is engaged to drive the sliding plate 12 to slide, which in turn drives multiple sets of sliding rods 11 to move. The extrusion block 10 compresses the extrusion spring to retract, and the positioning post 13 is simultaneously driven to disengage from the inside of the positioning hole. Then, the shock-absorbing component, together with the connecting plate 4 and the insertion block 9, can be lifted and separated from the buffer plate 2. The assembly operation can also be performed by reversing the above steps.

[0026] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the second positioning assembly includes a docking assembly, a rotary pressing assembly, and an abutment assembly. The docking assembly includes multiple sets of movable rods slidably connected inside the wear-resistant plate 3. A rotating groove is formed inside the wear-resistant plate 3 on the outside of the movable rods. A rotating disk 14 is slidably connected inside the rotating groove. The rotating disk 14 is rotatably connected to the movable rods. First springs are installed between the two ends of one side of the rotating disk 14 and the inner wall of the rotating groove. A mounting base 15 is installed at one end of the mounting sleeve 6. A docking groove 16 is formed on the top of the mounting sleeve 6. The cross-section of the docking groove 16 is cross-shaped. A locking block 17 is installed at one end of the movable rod. The docking groove 16 and the locking block 17 are slidably connected. Then, the locking block 17 is aligned with the docking groove. Pushing into the transverse notch in the staggered port 16, the pull ring 25 is engaged, pressing the movable rod downwards, causing the rotating disk 14 to stretch the first spring. The two ends of the locking block 17 contact the abutment blocks 22 on both sides, and the first slope 24 and the second slope contact each other. The abutment block 22 is compressed, causing the third spring to retract. After the locking block 17 and the fixing block 23 installed on it continue to move downwards and offset the abutment block 22, the abutment block 22 rebounds. At this time, the positioning block 20 is engaged in the positioning groove, and the docking disk 19 compresses the second spring to retract. Then it is pulled back a certain distance, and the fixing block 23 is engaged in the inner side of the fixing groove. The abutment block 22 and the docking disk 19 press the locking block 17 together, completing the fixed assembly with the wear-resistant plate 3.

[0027] In this embodiment, as Figure 1 , Figure 3 and Figure 4As shown, the rotary extrusion assembly includes a mounting groove at one end inside the mounting sleeve 6, the inner side of which communicates with the inner side of the docking groove 16. A base 18 is rotatably connected to the inner side of the mounting groove. A second spring is installed at both ends of the top of the base 18, and a docking plate 19 is installed at the top of the second spring. A positioning block 20 is installed at the top of the docking plate 19. A positioning groove that engages with the positioning block 20 is opened at the bottom of the locking block 17. The abutment assembly includes abutment grooves 21 at both ends of the inner wall of the mounting groove. A third spring is installed inside the abutment grooves 21, and an abutment block 22 is installed at one end of the third spring. The abutment block 22 is engaged with the abutment groove 21. Fixing blocks 23 are installed at both ends of the top of the locking block 17. The bottom end of 22 is provided with a fixing groove that engages with the fixing block 23. The cross-section of the locking block 17 is T-shaped. Both ends of the locking block 17 are provided with a first slope 24. The ends of the two sets of abutting blocks 22 near the locking block 17 are provided with a second slope. The first slope 24 and the second slope are in contact with each other. The top corner of the wear-resistant plate 3 is provided with an operating groove. The end of the movable rod extending to the inside of the operating groove is rotatably connected to a pull ring 25. Furthermore, pressing the movable rod causes the locking block 17, the mating plate 19 and the first spring to move down, and then the base 18 rotates to move away from the abutting block 22, so that the locking block 17 is pulled out from the longitudinal notch in the staggered port of the mating groove 16, completing the disassembly and separation from the wear-resistant plate 3.

[0028] The implementation principle of a noise reduction and shock absorption treadmill plate in this application embodiment is as follows: The sliding plate 12 is slid along with the latching groove, simultaneously moving multiple sets of sliding rods 11. The pressing block 10 compresses the pressing spring to retract, and the positioning post 13 is simultaneously moved away from the inner side of the positioning hole. Then, the shock absorption component, along with the connecting plate 4 and the plug-in block 9, can be lifted and separated from the buffer plate 2. Conversely, the above steps can be reversed for assembly. The locking block 17 is aligned with the transverse notch in the intersecting port of the docking groove 16 and pushed in. The pulling ring 25 is pressed downwards to push the movable rod, causing the rotating disk 14 to stretch the first spring. The two ends of the locking block 17 contact the abutment blocks 22 on both sides, and the first slope 24 and the second slope contact each other. When 22 is compressed, the third spring retracts. After the locking block 17 and the fixing block 23 installed on it continue to move downward and offset the abutment block 22, the abutment block 22 rebounds. At this time, the positioning block 20 is inserted into the positioning groove, and the docking plate 19 compresses the second spring to retract. Then it is pulled back a distance, and the fixing block 23 is inserted into the inner side of the fixing groove. The abutment block 22 and the docking plate 19 press the locking block 17 together, completing the fixed assembly with the wear-resistant plate 3. Pressing the movable rod drives the locking block 17, the docking plate 19 and the first spring to move downward, and then rotates with the chassis 18 to offset the abutment block 22 and move, so that the locking block 17 is pulled out from the longitudinal notch in the staggered port of the docking groove 16, completing the disassembly and separation from the wear-resistant plate 3.

[0029] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
