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
The present invention relates to spring technical field, be specially a kind of anticreep Spring screws.
Background technique
At present, when carrying out element assembling, Spring screws is conventional assembly, often there are some problems when assembling in Spring screws, such as spring end is easily stuck in annular slot, thus causes Spring screws to move up and down, elastic force can not be provided, and then cannot be normally sealed, have a strong impact on the fastening anticreep original intention of screw, also can have a huge impact operation.
Summary of the invention
The object of the present invention is to provide a kind of anticreep Spring screws, to solve the problem proposed in above-mentioned background technology, structure is simple, reasonable in design, is easy to manufacture and processing.
For achieving the above object, the invention provides following technological scheme: a kind of anticreep Spring screws, comprise screw thread, screw rod, Compress Spring and spiro rod cap, the upper end of described screw rod is provided with screw thread, the below of described screw rod is provided with spiro rod cap, the bottom surface of described spiro rod cap is provided with shatter-resistant rubber, described shatter-resistant rubber is connected with being fixed by welding between spiro rod cap, one end of described Compress Spring is arranged on the inside of spiro rod cap, described screw rod is installed helical thread portion screw diameter from top to bottom and changes from small to big gradually.
Preferably, the external layer of described screw rod and spiro rod cap all scribbles the anti-coating that gets rusty.
Preferably, described Compress Spring is a circle, and can occur when being under pressure elastic strain to the entirety of Compress Spring and the upper surface of spiro rod cap crossing.
Compared with prior art, the invention has the beneficial effects as follows: a kind of anticreep Spring screws, structure is simple, reasonable in design, be easy to manufacture and processing, diameter is that draw-in groove increases gradually to nut direction, therefore the end of Compress Spring can be avoided to be stuck in draw-in groove, stabilize the quality of assembling processing procedure, improve the yield of completed knocked down products, there is higher economic benefit and application prospect widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, screw thread, 2, screw rod, 3, Compress Spring, 4, spiro rod cap, 5, shatter-resistant rubber.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the invention provides a kind of technological scheme: a kind of anticreep Spring screws, comprise screw thread 1, screw rod 2, Compress Spring 3 and spiro rod cap 4, the upper end of described screw rod 2 is provided with screw thread 1, the below of described screw rod 2 is provided with spiro rod cap 4, the bottom surface of described spiro rod cap 4 is provided with shatter-resistant rubber 5, described shatter-resistant rubber 5 is connected with being fixed by welding between spiro rod cap 4, one end of described Compress Spring 3 is arranged on the inside of spiro rod cap 4, described screw rod 2 is installed screw thread 1 part screw rod 2 diameter from top to bottom to change from small to big gradually, the external layer of described screw rod 2 and spiro rod cap 4 all scribbles the anti-coating that gets rusty, described Compress Spring 3 is a circle, and it is crossing with the upper surface of spiro rod cap 4 to the entirety of Compress Spring 3 that elastic strain can occur when being under pressure.
Concrete usage mode: the present invention in use, is arranged on workpiece to be fixed by the present invention, during reinforcing, the surface of workpiece is compressed Compress Spring 3, and when work piece, the moment stops screw to get loose by Compress Spring 3.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
