Disconnecting prevention spring screw

Abstract

The invention discloses a disconnecting prevention spring screw which comprises a thread, a screw rod, a compression spring and a screw rod cap. The thread is arranged at the upper end of the screw rod, the screw rod cap is mounted on the lower portion of the screw rod, crash-proof rubber is mounted on the bottom face of the screw rod cap and fixedly welded with the screw rod cap, one end of the compression spring is mounted in the screw rod cap, the diameter of the screw rod of the thread portion mounted on the screw rod is gradually enlarged from small from top to bottom, a rust-proof coating is coated on the outer surface layers of the screw rod and the screw rod cap, and one ring of compression spring can deform to integrally intersect with the upper surface of the screw rod when pressure is applied on the compression spring. The disconnecting prevention spring screw is simple in structure, reasonable in design and easy to manufacture and machine, the diameter is enlarged from an clamping groove to a nut, so that the tail of the compression spring can be prevented from being clamped into the clamping groove, the quality of an assembly process is stabled, and the yield rate of assembly products is increased.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to an anti-off spring screw. Background technique [0002] At present, spring screws are commonly used components when assembling components. Spring screws often have some problems during assembly. For example, the end of the spring is easily stuck in the ring groove, which makes the spring screw unable to move up and down and cannot provide elastic force. Then it cannot be locked normally, which seriously affects the original intention of fastening and anti-off of the screw, and also has a great impact on the operation. Contents of the invention [0003] The object of the present invention is to provide an anti-loosening spring screw to solve the problems raised in the above-mentioned background technology, which has a simple structure, a reasonable design, and is easy to manufacture and process. [0004] In order to achieve the above object, the present invention provides the f...

Problems solved by technology

[0002] At present, spring screws are commonly used components when assembling components. Spring screws often have some problems during assembly. For example, the end of the spring is easily stuck in the ring groove, which makes the spring screw unable to move up and down and cannot provide elastic force. In turn, it cannot be locked normally, which seriously affects the original intention of the screw's fastening and anti-loosening, and will also have a great impact on the operation.
