Abstract

The utility model discloses a clamp type semi-spring, and the key is that: a plurality of groups of corresponding upper and lower bidirectional direct clamp teeth are disposed inside and outside of each steel ring of a tower shape spring of a direct clamp type tower shape semi-spring, and when the tower shape spring is compressed, the corresponding upper and lower bidirectional direct clamp teeth engaged with one another. A pin clamp type semi-spring combines the tower shape spring, a columnar spring and the direct clamp type tower shape semi-spring with a pin clamp, the pin clamp consists of a pin clamp seat and a pin clamp post, the top part of the pin clamp post is T-shaped, the top part of the spring is fixed under a T-shaped top plate of the pin clamp post, and the bottom part thereof is fixed on the pin clamp seat, a spring tongue is arranged in the pin clamp seat, and a plurality of groups of V-shaped clamp teeth are arranged on the pin clamp post. The top part of the pin clamp post is pressed into the pin clamp seat under outside force, the V-shaped clamp teeth of the pin clamp post force the spring tongue to retract, and after the pin clamp post V-shaped clamp teeth pass through the spring tongue, the spring tongue rebounds to be clamped on the pin clamp post V-shaped clamp teeth. The clamp type semi-spring will not rebound to the home position after greatly relieving the impact force, and has advantages of simple structure, important purposes and great promotion value.

Description

Clamp type semi-spring

Affiliated technical field

The utility model relates to a kind of spring, specifically, is the clamp type semi-spring that can obviously slow down the original position that do not rebound back again after the impact force.

Background technique

At present, vehicle and a lot of machinery all are extensive use of spring, and the also unmanned design of half spring of original position is used but spring can not rebound back after being compressed.In fact, utilize the elasticity of spring, but make it not produce rebounding force and become half spring property, it is installed in the anti-strong position towards impact force of needs, the boxing glove of when boxing contest, wearing, just can slow down bump strength greatly, not produce the rebounding force that is directly proportional with impact force again, purposes is very extensive.The society that particularly current various vehicles are many is used for automobile and is mounted to semi-spring bumper, and that is the important feature of automobile production competition among enterprises certainly.Because of present bumper mainly based on the steel plate steelframe, be aided with the plastic-steel shell, do not have the effect that slows down impact force basically, the safety protection effect to passengers inside the car when car crash does not have substantially.China has about 100,000 people be killed in an automobile accident every year, death when wherein considerable part is clashed into by force, if semi-spring bumper is arranged, just can slow down greatly when two cars collide and collide the strength of hitting, can strong push-and-pull not cause injury for the second time again because of the rebounding force of spring to passengers inside the car, does passengers inside the car's life safety open and is not very secure?

Summary of the invention

In order to make do not rebound the back again problem of original position of spring after obviously slowing down impact force, the utility model provides a kind of clamp type semi-spring, is divided into direct clamping type tower half spring and pin clamp type semi-spring.The original position that can not rebound back after this clamp type semi-spring is compressed can obviously be slowed down bump strength, does not produce again and the rebounding force that is directly proportional towards impact force.

The technological scheme that its technical problem that solves the utility model adopts is: described clamp type semi-spring is that the tower spring is combined with straight card, the tower spring, and the column type spring combines with the pin card, and the tower spring combines with straight card and pin card, and its key is:

1, the tower spring is combined into direct clamping type tower half spring with straight card, it be at the tower spring except that the foundation ring, the corresponding two-way up and down hook-shaped inside and outside straight latch of the many groups of arranged outside in each steel rim of spring.The tower spring must be the spring structure that can be compressed into a plane under the mutual interlocking pattern of inside and outside straight latch, because expansible and retraction elasticity when spring has pressurized, when the tower length of spring compressed, each is organized and correspondingly goes up to hook-shaped outside straight latch just with compressing intensity of force, depress one by one with adjacent springs steel ring separately on the corresponding directly mutual interlock of latch to hook-shaped in down, the tower spring original position that just can not rebound back.

This scheme in the specific implementation, tower steel rim of spring inboard can be made oblique point hook-shaped downwards in direct neck, the hook-shaped outer straight latch of arranged outside also can be made the tower steel rim of spring outside the oblique point hook-shaped outer direct neck that makes progress, the inboard be provided with hook-shaped in latch directly.Direct neck is equivalent to numerous straight latches and connects together, and its structural principle is identical with straight latch.

2, tower spring, column type spring, direct clamping type tower half spring combine with the pin card, become the pin clamp type semi-spring, can be divided into pin cassette tower half spring, pin cassette column type half spring and two clips tower half spring.The pin card is made up of pin card post and pin deck, pin card post is the steel pole of square or other shapes, the top is "T"-shaped, penetrate in the pin deck from the spring center of top, pin card post is provided with many group " V " shape latches, and pin card post is when length of spring compressed is passed the pin deck, " V " shape latch compressing pin deck inner spring gyrus lingulais on the pin card post is contracted, " V " shape latch on pin card post promptly rebounds out by the rear spring tongue, is stuck on pin card post " V " the shape latch spring original position that just can not rebound back.

This scheme in the specific implementation, the pin card of pin cassette tower half spring, two clips tower half spring and pin cassette column type half spring also can be arranged on outside the spring ring, outside the spring a plurality of pin cards can also be set, a plurality of similar springs also can be installed in a pin card next door.

This practical beneficial effect is: when the powerful collision of quilts such as the object that clamp type semi-spring is set, vehicle is hit, spring have slow down greatly under self elastic force effect the collision of this object, vehicle etc. hit strength after, the clamp type semi-spring original position that can not rebound back, thereby just do not produce and the rebounding force that is directly proportional towards impact force, hit the extent of damages such as object, vehicle by collision and alleviate greatly, personnel can not be subjected to the secondary injury that springback power is brought yet on the vehicle.Clamp type semi-spring is simple in structure, and is easy to manufacture, and cost is not high, of many uses important, very easily applies.
