Description

Technical Field

[0001] This utility model relates to the technical field of chainsaw shock absorbers, and in particular to a chainsaw shock absorber. Background Technology

[0002] Chainsaws are powered by small gasoline engines, but as handheld tools, the high-frequency vibrations generated by gasoline engines can be difficult for the operator's hands to withstand. Therefore, all chainsaws have a shock absorption system designed between the gasoline engine and the operating handle.

[0003] However, in the existing technology, when the chainsaw is working, the operator's hands are tightly gripping the operating handle. The shock absorber used to connect the chainsaw body and the operating handle mostly uses springs to buffer the vibration generated when the chainsaw is working. The shock absorption effect is generally average, and long-term use will cause certain damage to the operator's hands.

[0004] To address this issue, a chainsaw shock absorber was proposed. Utility Model Content

[0025] Specifically: the connecting component 3 and the shock-absorbing device 4 work together to buffer the vibration generated by the chainsaw. The shock-absorbing device 2 enhances the buffering and shock-absorbing capabilities. The hexagonal nut 5 limits the connection component 3. The device is installed on the chainsaw through the mounting plate 6.

[0026] In one embodiment, limiting rings 101 are fixedly sleeved on both sides of the surface of the operating handle 1.

[0027] Specifically, such as Figure 1 and 5 As shown: Two limiting rings 101 fix the fixing tube 201 in the middle.

[0028] In one embodiment, the buffer device 2 includes a fixed tube 201, a rubber pad 202 is fixedly embedded inside the fixed tube 201, the rubber pad 202 is fixedly sleeved on the surface of the operating handle 1, the two sides of the rubber pad 202 are respectively attached to the opposite sides of the two limiting rings 101, and a sponge sleeve 203 is fixedly sleeved on the surface of the fixed tube 201, the two ends of the sponge sleeve 203 are respectively fixedly sleeved on the surface of the two limiting rings 101.

[0029] Specifically, such as Figure 1 and 5 As shown: the rubber pad 202 is located between the operating handle 1 and the fixed tube 201, which plays a buffering role, and the sponge sleeve 203 is located on the surface of the fixed tube 201 to further reduce the vibration of the hand when operating the chainsaw.

[0030] In one embodiment, the connecting component 3 includes a connecting rod 301, the top of which is fixedly connected to the bottom of one end of the operating handle 1, and limit plates 302 are fixedly installed on both sides of the bottom surface of the connecting rod 301.

[0031] Specifically, such as Figure 1-3 As shown: Connecting rod 301 connects to operating handle 1. Limiting plate 302 moves within movable groove 402 and is fixed by hexagonal nut 5. Connecting rod 301 is connected to connecting plate 407, which compresses spring 404 and damper 405.

[0032] In one embodiment, the shock absorption device 4 includes a connecting sleeve 401. Movable grooves 402 are provided on both sides of the top of the connecting sleeve 401. Two threaded semi-rings 403 are fixedly installed on the top of the connecting sleeve 401. A spring 404 is fixedly installed on the bottom side inside the connecting sleeve 401. Two limiting plates 302 are movably embedded in the two movable grooves 402 respectively. The bottom surface of the connecting rod 301 is movably embedded in the inside of the connecting sleeve 401. A damper 405 is fixedly installed on the bottom side inside the connecting sleeve 401. The bottom of the damper 405 is fixed... A hemispherical seat 406 is fixedly installed inside the connecting sleeve 401. The bottom of the hemispherical seat 406 is fixedly installed on the bottom side inside the connecting sleeve 401. The damper 405 and the hemispherical seat 406 are both located inside the spring 404. A connecting plate 407 is fixedly installed on the top of the damper 405. Limiting plates 408 are fixedly installed on both sides of the connecting plate 407. The surface of the connecting plate 407 is movably embedded inside the connecting sleeve 401. The two limiting plates 408 are respectively movably inside the two movable slots 402. The top of the spring 404 is fixedly connected to the bottom of the connecting plate 407.

[0033] Specifically, such as Figure 1 , 2As shown in Figure 4: The movable groove 402 facilitates the movement of the limiting plate 302. When the chainsaw is working, the vibration generated is transmitted to the connecting rod 301 through the mounting plate 6 and the connecting sleeve 401. At the same time, the vibration is damped and buffered by the spring 404 and the damper 405 to reduce the vibration. The hemispherical seat 406 limits the spring 404.

[0034] In one embodiment, the hexagonal nut 5 is threaded onto the surfaces of two threaded half-rings 403.

[0036] In one embodiment, the top of the mounting plate 6 is fixedly mounted on the top of the connecting sleeve 401.

[0037] Specifically, such as Figure 1 As shown: Mounting plate 6 facilitates the installation of the device on the chainsaw.

[0038] Working Principle: When in use, this device is fixed to the surface of the chainsaw via the mounting plate 6. Vibrations during chainsaw use are transmitted through the mounting plate 6 and the connecting sleeve 401. The spring 404 and damper 405 inside the connecting sleeve 401 push and compress the connecting plate 407 and the connecting rod 301. During this compression process, the spring 404 and damper 405 buffer the vibration, thereby reducing the vibration transmitted to the surface of the operating handle 1. Additionally, a fixing tube 201 is fitted onto the surface of the operating handle 1. A rubber pad 202 is filled between the operating handle 1 and the fixed tube 201, and a sponge sleeve 203 is fitted on the surface of the fixed tube 201 to enhance the ability to withstand vibrations to the operator's hand. When repairing or replacing the spring 404 or the damper 405, simply loosen and remove the two hexagonal nuts 5 from the surfaces of the two threaded half-rings 403 on both sides, then lift the operating handle 1 to remove the connecting rod 301 from the connecting sleeve 401, and then remove the mounting plate 6 from the chainsaw to replace the shock absorber 4. This is simple, convenient, and easy to disassemble and repair.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
