Description

Technical Field

[0001] This utility model relates to the field of washers technology, specifically an anti-loosening washer. Background Technology

[0002] A washer is a part placed between a connected part and a nut. It is generally a flat metal ring used to protect the surface of the connected part from being scratched by the nut and to distribute the pressure of the nut on the connected part. There are many types of washers, such as flat washers, spring washers, anti-loosening washers, combination washers, and asbestos rubber washers. Washers are widely used in various mechanical equipment and structures, especially in situations where it is necessary to protect the surface of the connected part, distribute pressure, and prevent the nut from loosening.

[0003] In use, existing washers are generally clamped between the connector and the nut and fixed by external pressure. However, they are prone to loosening during long-term use, which can affect the use of the nut.

[0004] Therefore, those skilled in the art have provided an anti-loosening washer to solve the problems mentioned in the background art. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides an anti-loosening washer. By setting a clamping mechanism, the washer can be clamped on the side wall of the nut during use, achieving a further fixing effect. At the same time, it can effectively prevent the washer from loosening after long-term use, ensuring the good fixing effect of the nut. Secondly, by setting an adsorption mechanism, the washer can be directly adsorbed onto the nut and the connector, achieving a further fixing effect and preventing loosening, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-loosening washer includes a washer body, a clamping mechanism on the washer body, the clamping mechanism including a movable column slidably connected to the washer body, a clamping plate fixedly connected to one end of the movable column located outside the washer body, a connecting rod slidably connected to the lower inner wall of the washer body, the connecting rod being connected to the washer body by a compression spring, and a limit groove formed on the movable column.

[0008] As a further embodiment of this utility model, the clamping mechanism also includes a movable rod that passes through and is slidably connected to the washer body, and a trapezoidal block is fixedly connected to the lower end of the movable rod, with the trapezoidal block partially located inside the limiting groove.

[0009] As a further embodiment of this utility model, the clamping mechanism is provided in two sets, symmetrically distributed on the washer body, and the height of the clamping plate is greater than the height of the washer body.

[0010] As a further improvement of this invention, the lower surface of the trapezoidal block has a smaller cross-section.

[0011] As a further embodiment of this utility model, the washer body is provided with an adsorption mechanism, the adsorption mechanism including a first magnet embedded in the upper end of the washer body and a second magnet embedded in the lower end of the washer body.

[0012] As a further embodiment of this invention, the first magnet is used for adsorption connection between the washer body and the connector.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting up a clamping mechanism, the washer can be clamped onto the side wall of the nut during use, which provides a further fixing effect and effectively prevents the washer from loosening after long-term use, ensuring the good fixing effect of the nut. Secondly, by setting up an adsorption mechanism, the washer can be directly adsorbed onto the nut and the connector, which provides a further fixing effect and prevents loosening.

[0020] Please see Figures 1-4In this embodiment of the utility model, an anti-loosening washer includes a washer body 1, a movable post 2 is slidably connected through the outer wall of the washer body 1, the movable post 2 can move based on the washer body 1, and a clamping plate 3 is fixedly connected to one end of the movable post 2 located outside the washer body 1. When the washer is in use, the clamping plate 3 will firmly adhere to the surface of the nut to prevent the washer body 1 from loosening during use.

[0021] The movable column 2 is fixedly connected to the outer wall inside the washer body 1 with a connecting rod 7. The lower end of the connecting rod 7 is slidably connected to the inner wall of the washer body 1. The side of the connecting rod 7 is fixedly connected to the washer body 1 through a compression spring 8. When the clamping plate 3 is not subjected to external force, it can return to its original position under the action of the compression spring 8.

[0022] A movable rod 4 is slidably connected through the upper end of the washer body 1. A trapezoidal block 5 is fixedly connected to one end of the movable rod 4 inside the washer body 1. A limiting groove 6 is provided on the movable column 2. The trapezoidal block 5 is located inside the limiting groove 6. When the trapezoidal block 5 moves downward based on the washer body 1, the movable column 2 can be moved by the trapezoidal block 5 and the limiting groove 6, thereby realizing the movement of the clamping plate 3.

[0023] A first magnet 9 is embedded at the upper end of the washer body 1, and a second magnet 10 is embedded at the lower end of the washer body 1. The washer body 1 is attracted and fixed to the surface of the connector and the nut by the first magnet 9 and the second magnet 10 respectively, which further prevents the washer from loosening.

[0024] The working principle of this utility model is as follows: When a washer is needed, the washer body 1 is first placed in an appropriate position on the connector and initially connected to the connector by the second magnet 10 to prevent loosening. Then, the nut is placed above the washer body 1, and the nut is rotated using a tool. As the nut rotates, it gradually moves downward, thereby pushing the movable rod 4 downward. When the movable rod 4 moves, it pushes the trapezoidal block 5 downward, and then pushes the moving column 2 to move through the limiting groove 6. When the moving column 2 moves, it causes the clamping plate 3 to retract towards the washer body 1, and finally firmly clamps it on the surface of the nut. Based on the nut, the washer body 1 is fixed again, further preventing it from loosening during use.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
