Abstract
The utility model provides a two -way wind spring, by spool, down wind spring, go upward the wind spring and forms, the wind spring of being issued to the lower level that can draw and use in the apparatus and a stretch out the end and be equipped with the connecting hole that goes upward the wind spring and folds together, the fixed book of one end connects on the spool, the other end roll up the outside go upward that the wind spring is straight upwards to be stretched out, roll up and stretch out downwards in that the down wind spring of inboard is straight, the wind spring. The utility model discloses because it can be to the tensile wind spring of opposite direction to be equipped with down wind spring and to go upward two wind springs, so, join in marriage and be equipped with the utility model discloses a shaft -like product has biaxial stretching's function, can satisfy flexible more swiftly, and the volume is littleer, uses, carries demands such as more convenient.
Description
Technical field
Two-way wind spring used in a kind of stretchable apparatus.
Background technology
There is unidirectional wind spring technical pattern in the past, be frequently utilized for needing the shaft-like product of stretcher strain.The pull bar of such as draw-bar box,
The support bar of spider, hand-held walking stick etc., there is delicate structure, easy to use, the features such as being easy to carry, general by people
All over welcome.
Although unidirectional wind spring in the past has above various features, due to being simple tension, still there is stretching, become
Shape efficiency is low, slow-footed shortcoming it is impossible to meet the modern life to the product using stretching structure, stretch faster, volume is more
Little, using carrying the demand such as more convenient.
Content of the invention
The purpose of this utility model is so as to have the function of biaxial tension by the design of two-way wind spring, can meet
Using rod-like structure product of the present utility model, stretch faster, volume is less, using, carry the demand such as more convenient.
This utility model is made up of spool, descending wind spring, up wind spring, and descending wind spring and up wind spring stack, and one
On spool, the up wind spring in outside for the other end volume is straight to be protruded upward the fixing cigarette in end, and the descending wind spring in inner side for the volume is put down
Directly extend downwardly from, the external part of wind spring is provided with connecting hole.
This utility model due to being provided with descending wind spring and two wind springs that can stretch round about of up wind spring, so,
It is equipped with rod-shaped articles of the present utility model, there is the function of biaxial tension, can meet flexible faster, volume is less, using,
Carry the demand such as more convenient.
