Description

Anti-distortion butterfly spring

Technical Field

The utility model relates to a disc spring technical field, concretely relates to antitorque bent disc spring.

Background

The disc spring is also called a Belleville spring washer, is in a conical disc shape, can be used singly or in series or in parallel, bears static or dynamic loads acting along the axial direction at the upper inner edge and the lower outer edge, deforms after being compressed until being flattened, and is used as live load in the form of stored energy. When necessary, automatically converts into additional compression load required by sealing, so as to reduce the continuous requirement of tightening in the use of gaskets and packing.

The prior art has the following defects: the conventional belleville spring is fixedly assembled by an upper disc and a lower disc, a certain gap exists between the two discs, so that the upper disc and the lower disc have a certain extension space, and then sufficient elastic extension is provided by a considerable amount of superposition to play a role, but the conventional belleville spring has poor twisting resistance, can be flattened under the action of applying strong pressure to the belleville spring, but can cause the torsion and deformation of the belleville spring under a long-time flattening state, so that the belleville spring cannot be restored to the original state, is damaged, reduces the elastic effect of the belleville spring, and seriously reduces the service life of the belleville spring

Therefore, it is necessary to develop an anti-torsion belleville spring.

SUMMERY OF THE UTILITY MODEL

In order to achieve the above object, the present invention provides the following technical solutions: an anti-twist butterfly spring comprises an upper disc, a first lower disc and a cylinder, wherein anti-twist structures are arranged on the inner wall of the upper disc and the outer wall of the first lower disc, so that the anti-twist performance of the butterfly spring is improved.

Preferably, the anti-twisting structure comprises a first inner disc, the inner wall of the upper disc is provided with the first inner disc, and the outer wall of the first lower disc is provided with a second inner disc.

Preferably, the anti-twisting structure comprises a second lower disc, the bottom of the first lower disc is provided with the second lower disc, and the inner wall of the second lower disc is provided with a third inner disc.

Preferably, the outer wall of going up the video disc is installed and is gone up connecting portion, connecting portion are down installed to the outer wall of video disc under No. one, go up connecting portion and the outer wall of lower connecting portion and install the connecting block, and the connecting block has a plurality of, the bolt is installed to the inner wall of connecting block.

Preferably, the top of the cylinder is provided with a pressing plate in a sliding manner, and the bottom of the cylinder is provided with a connecting column.

The utility model has the advantages that:

1. the utility model discloses an install interior video disc, no. two interior video discs, no. two lower video discs, no. three interior video discs have realized having improved the function of belleville spring antitorque nature, compress belleville spring to the limit, remove the pressure on the belleville spring again, no. one interior video disc makes the video disc reconversion, no. two interior video discs make video disc reconversion under No. one, no. three interior video discs make No. two lower video disc reconversion to the function that belleville spring antitorque nature has been improved has been realized.
