Description
Technical field
The utility model relates to handware manufacture fields, specially a kind of to be bonded curved fixed screw.
Background technique
Screw is the physics and mathematical principle of the inclined-plane circular rotating and frictional force using object, is fastened by easy stages
The tool of implements parts is industrial necessity indispensable in daily life, and screw industrially bears vital task, as long as
There is industry on the earth, the function of screw is just forever important.Screw is the joint invention in people's production and living over the past thousands of years,
From the point of view of application field, it is the first major invention of the mankind.
Existing screw is mostly that monomer structure cannot well protect screw rod, because of no pair when not using screw
Screw rod is protected so screw rod surface can be made to be aoxidized, thus can reduce screw service life, and because existing spiral shell
Silk is monomer structure, so non-slip texture at most only has two layers, it is not anti-skidding enough in some cases, it is possible that causing screw sliding
Silk, causes robust structure avalanche, and existing screw is not directed to the design of ball-type product, leads to the spiral shell in firm spherical product
Silk cannot be bonded completely, cause part built on the sand, it is therefore desirable to a kind of to be bonded curved fixed screw.
Summary of the invention
It is bonded curved fixed screw the purpose of this utility model is to provide a kind of, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the utility model provides the following technical solutions: it is a kind of to be bonded curved fixed screw, including
Screw terminal, the screw terminal outside is provided with outer sleeve, and perpendicular row threading, institute are evenly arranged on the outside of outer sleeve lower half portion
Stating outer sleeve top half is in ellipse arc, and the middle position at the top of the screw terminal is connected with spring, and the end of spring is worn
It crosses outer sleeve and is connected with inner sleeve, the top on the outside of the inner sleeve is provided with gear tooth line, the centre at the top of the screw terminal
Screw rod is provided at position, and screw rod passes through outer sleeve and inner sleeve and the top for extending to inner sleeve, the screw rod
Outside is evenly arranged with screw thread threading.
Preferably, the screw rod bottom is welded and fixed with screw terminal, and screw rod is cylindrical structure, the screw rod
It is made of stainless steel material.
Preferably, the screw rod is located on the inside of spring.
Preferably, the inner sleeve is hollow structure.
Preferably, the spring is welded and fixed with screw terminal.
Compared with prior art, the utility model has the beneficial effects that this kind is bonded outside curved fixed screw outer sleeve
Side is evenly arranged with perpendicular row threading, when craft being facilitated to screw fastening, increases frictional force, increasing screws impetus, and screw terminal is set as
Ellipse arc, this design can be such that this screw is more bonded when being mounted on spherical product, be bonded screw with product seamless, fastening effect
Fruit is more preferable, has spring to be connected inside outer sleeve and inner sleeve, squeezes inner sleeve, can make inner sleeve toward in outer sleeve with compressed spring
Reduction of area is into exposing screw rod, loaded on needing on fixed product, protection screw rod can also be played when not using screw
Effect, while having a circle gear tooth line below inner sleeve, it can reinforce the frictional force between screw and product, the fastening effect of reinforcement,
There is screw thread threading in screw rod, further increases the fastening effect of screw, while screw rod end is planar design, rather than prong
Design, in this way when screw is mounted on product, just damage product not easy to scratch, this screw are tight for all kinds of metal plate class products
Gu being especially suitable for the fastening of ball shape metal plate product, fastening effect is good, when installation damage product not easy to scratch.
