Description

Technical Field

[0001] The utility model relates to the technical field of spring washers, in particular to an improved long-life spring washer. Background Art

[0002] Washers are commonly used fasteners, usually set between the connected parts and nuts. They are generally flat metal rings, used to protect the surface of the connected parts from being scratched by the nuts and to disperse the pressure of the nuts on the connected parts. Fastening washers are the most widely used parts on the market, but the structural styles of fastening washers on the current market are relatively uniform.

[0003] The utility model patent application document with publication number "CN214063534U" discloses a spring washer, which is mainly composed of a spring washer body and an anti-loosening protrusion. The spring washer of this technical solution can better prevent the nut or bolt from loosening when the bolt or nut is subjected to strong vibration.

[0004] The spring washer disclosed in the above document has the following defects: the technical solution may cause the shape to be squeezed and changed when used for a long time, thereby causing damage and shortening its service life.

[0005] It can be seen from this that the existing spring washers do not have a long service life, and it is necessary to improve the existing deficiencies and provide an improved spring washer with a long service life. Summary of the invention

[0006] The utility model aims to provide an improved spring washer with a long service life to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is an improved high-life spring washer, comprising a first washer, a first groove is opened on the upper surface of the first washer, a buffer structure is arranged inside the first groove, the number of the buffer structures is fixed to five, the buffer structure comprises a base, a sleeve, a first spring, a second spring, a connecting block, and a fixing column, the base is fixedly installed on the inner bottom of the first groove, the sleeve is fixedly installed on the upper surface of the base, the first spring is movably installed on the upper surface of the base, the second spring is movably installed on the inner bottom of the sleeve, the connecting block is movably installed on the inner wall of the sleeve, and the fixing column is fixedly installed on the upper surface of the connecting block.

[0009] Furthermore, a rubber pad is fixedly mounted on the upper surface of the first gasket, and a first wear-resistant layer is fixedly mounted on the lower surface of the first gasket.

[0010] Furthermore, a second groove is provided on the inner wall of the first gasket, the number of the second grooves is fixed at two, a mounting plate is fixedly installed inside the second groove, a third spring is movably installed on one side of the mounting plate, a clamping block is movably installed on one end of the third spring, and a first anti-slip stripe is provided on one side of the clamping block.

[0011] Furthermore, a second gasket is disposed on the upper surface of the fixing column, a limiting hole is provided on the lower surface of the second gasket, and the fixing column is engaged with the limiting hole.

[0012] Furthermore, a second wear-resistant layer is fixedly mounted on the upper surface of the second washer, and a plurality of second anti-slip stripes are provided on the upper surface of the second wear-resistant layer.

[0013] Furthermore, a nut is movably mounted on the lower surface of the first wear-resistant layer.

[0014] Furthermore, a bolt is movably installed inside the second washer, the bolt is connected to the nut through the first washer, and the peripheral side surface of the bolt abuts against the clamping block.

[0015] The utility model has the following beneficial effects:

[0016] (1) When the nut and bolt are tightened by the buffer structure of the utility model, the bolt presses down the second washer, the second washer presses down the fixing column, the fixing column presses down the connecting block and the first spring moves downward, the connecting block presses down the second spring, so that the connecting block enters the interior of the housing, and then the first washer and the second washer fit together. The rubber pad arranged on the surface of the first washer can prevent the second washer and the first washer from being damaged by pressure when they fit together. The buffer structure can buffer the downward pressure of the bolt on the washer to protect the surface of the washer from being damaged by pressure, thereby increasing the overall service life.

[0017] (2) The utility model places the washer on the upper surface of the nut and the bolt is installed. The arc-shaped design of the upper surface of the clamping block enables the bolt to press the clamping block into the interior of the second groove. After the bolt enters, the clamping block pops out to clamp the bolt so that the washer will not be offset during installation, so that the washer is more fully stressed, which greatly increases practicality.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
