Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electric tools, and in particular to an anti-slip and shock-absorbing mechanism of an electric tool. Background Art
[0002] In existing power tools, bearings serve as supporting components for shaft components. Bearings are often installed in the power tool housing by pressing. For some power tools that rotate at high speeds, such as electric drills and angle grinders, the bearings may slip after long-term use, thereby affecting the overall use.
[0003] In addition, for lithium-ion power tools, the battery pack is plugged into the socket on the power tool. In the existing structure, after the two are plugged in, the battery pack and the socket may become loose due to assembly problems or long-term use, which may cause poor circuit contact and easy entry of dust and debris, which will damage the power tool in the long run.
[0004] The above contents are only used to assist in understanding the technical solution of the present application, and do not constitute an admission that the above contents are the closest prior art to the present application. Summary of the invention
[0005] Based on this, the present application provides an anti-slip and shock-absorbing mechanism for an electric tool to solve one of the above-mentioned technical problems.
[0006] The technical solution adopted by the present application to solve its technical problems is, including: a bearing for supporting the output rotation of the electric tool; a shell, the bottom end of the shell is provided with a socket that cooperates with an external battery pack, and the interior of the shell is provided with a bearing seat for accommodating the bearing; a first rubber shock-absorbing member is installed inside the bearing seat and abuts against the outer periphery of the bearing, and is used to absorb and disperse the vibration caused when the electric tool is started to prevent the bearing from slipping due to vibration; a second rubber shock-absorbing member is fixedly arranged at one end of the socket connected to the battery pack, and is used to increase the friction between the socket and the battery pack.
[0007] In some embodiments, a receiving cavity for receiving the first rubber shock-absorbing component is defined in the bearing seat.
[0008] In some embodiments, a spring is fixedly disposed at the bottom of the accommodating cavity, and the first rubber shock-absorbing member is connected to the spring.
[0009] In some embodiments, convex ribs are formed on the outside of the accommodating cavity.
[0010] In some embodiments, the first rubber shock absorbing member and the second rubber shock absorbing member are substantially cylindrical in shape.
[0011] In some embodiments, the first rubber shock-absorbing member is substantially in the shape of a cuboid and has an arc-shaped contact surface.
[0012] In some embodiments, a groove for accommodating the second rubber shock absorber is formed at one end of the socket that cooperates with the battery pack.
[0013] The beneficial effect of the present application is that the present application adopts a rubber shock absorber to abut against the outer periphery of the bearing. The rubber shock absorber can effectively absorb and disperse the vibration caused by the power tool at high speed to prevent the bearing from slipping. At the same time, the rubber shock absorber is installed at the socket to reduce the possibility of the battery pack loosening due to vibration, which greatly improves the safety of the power tool when in use.

[0024] Specifically, a first rubber shock absorber 4 is installed in the bearing seat 32 that accommodates the bearing 2. When the bearing 2 enters high-speed rotation, the first rubber shock absorber 4 can effectively reduce the vibration caused by the bearing 2, and prevent the bearing 2 from slipping due to high-speed rotation and causing internal damage to the power tool. At the same time, a second rubber shock absorber 5 is provided at the socket 31 to increase the friction with the battery pack 1 and prevent the battery pack 1 from loosening due to vibration.
