Description
Technical field
The utility model is related to spring art, more particularly to a kind of protection type torsion spring.
Background technology
Spring is a kind of using the elastic machine components come work.The part being made of elastomeric material is sent out under external force
Raw deformation, restores to the original state again after removing external force.Also " spring " is made.Typically it is made of spring steel.The species complexity of spring is various, presses
Shape point, mainly there is helical spring, scroll spring, flat spring, heterotypic spring etc..For Spring Industry, shape for a long time
Into low-grade common spring, drug on the market, expensive goods (high intensity, high stress, different in nature part, special material) quilt that supply falls short of demand
Dynamic situation.The yield of China's Spring Industry has tended to saturation, all kinds of according to expert statistics China spring year output up to 4,000,000,000
Spring product has 21 major classes, more than 1600 kind, mainly have valve spring, bearing spring, diaphragm spring, damping spring,
Hydraulic spring grease cup, oil pump spring, disk spring, high temperature spring, jump ring, extension spring, torsion spring, stage clip, scrollwork spring and different in nature spring etc..
Spring Industry is especially Shanghai, Tianjin, Guangzhou, Shandong, Changchun, Chongqing than faster in " eight or five ", the enforcement period of the ninth five-year plan development
Very fast Deng regional development, also there is different degrees of development in other areas, generally speaking more much better than other industry.Automobile, rub
Motorcycle, power assist vehicle, internal combustion engine, electric, instrument etc. will also develop, and the development of these industries will drive the development of Spring Industry.
Spring needs to carry out pressure test after completing, and torsionspring (Torsion Spring) is design original in all spring classifications
The complex one kind of reason, the change of pattern is also quite active, therefore theory involved during design is also the most cumbersome；Existing torsion spring
Often there is the situation that fracture or fixed termination come off in load bearing process, larger inconvenience is brought to user.
Based on above reason, it is necessary to a kind of protection type torsion spring is devised, by setting steel wire rope, can be very good to prevent
Only after torsion spring fracture, coming off or slipping for equipment is caused；By setting welding hard point, can protective terminal well it is antitorque
Ability, screw is determined by setting, after torsion spring and external equipment stable connection, trip bolt of screwing on, it is to avoid external equipment is easily
Come off, improve torsion spring using effect, more convenient, simple and practical, i.e., a kind of protection type torsion spring.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of protection type torsion spring.
The utility model is to be achieved through the following technical solutions：
A kind of protection type torsion spring, including torsion spring body, link, the torsion spring body or so two ends are fixed on corresponding company
Connect on frame, it is characterised in that：The link lower end is vertically arranged with interior axle respectively, and steel wire rope is provided between the interior axle,
The steel wire rope two ends are separately fixed in corresponding interior axle by mushroom-shaped locking cap, and the steel wire rope is through being arranged on torsion spring
In body, the link outer end is accordingly vertically arranged with the longitudinal axis, and the outer end of the longitudinal axis is provided with trip bolt.
Further, the link is provided with welding hard point with corresponding longitudinal axis corner connection.
Further, the torsion spring body two ends are fixed on corresponding link by welding manner.
Further, the longitudinal axis is in a center of symmetry relative to torsion spring body, and the interior axle is relative to torsion
Spring body is in a center of symmetry.
Further, the link and the corresponding longitudinal axis and the integrated shaping of interior axle.
Compared with prior art, the beneficial effects of the utility model are：It is the utility model simple structure, reasonable in design,
By setting steel wire rope, after can be very good to prevent torsion spring to be broken, coming off or slipping for equipment is caused；Strengthened by setting welding
Point, can protective terminal well anti-twisting property, determine screw by setting, it is stubborn after torsion spring and external equipment stable connection
Upper trip bolt, it is to avoid external equipment comes off easily, improves torsion spring using effect, more convenient, simple and practical.
