Abstract

The utility model aims at providing a spiral spring with the changeable length to enlarge the range of application of the spiral spring. An opening inner cavity is formed in the top end of the spiral spring with the changeable length, and the bottom end of the spiral spring can be clamped into the inner cavity. When the spiral spring with the changeable length is used, the bottom end of a spring on the upper portion can be inserted into the inner cavity in the top end of a spring on the lower portion, accordingly, two or more spiral springs are connected mutually, and the length of the spring is changed. The spiral spring with the specific length does not needed to be manufactured according to specific application occasions, cost is saved, and the period for manufacturing the spiral spring is shortened.

Description

A kind of adjustable length helical spring
Technical field
The utility model belongs to field of mechanical technique, specially refers to a kind of helical spring.
Background technique
Spring is a kind of mechanical parts that utilize elasticity to carry out work, in order to motion, the mitigation of controlling parts, impacts or shakes, stores up the size of energy, measuring force etc., is widely used in machine, instrument.Traditional helical spring has a variety of length specifications, uses the spring of different length according to different occasions.But in some occasion, just be difficult to search out the spring of appropriate length, can only customize, increased cost and cycle.
The model utility content
The purpose of this utility model is to propose a kind of adjustable length helical spring, to increase its Applicable scope.
Adjustable length helical spring top of the present utility model is provided with open lumen, and helical spring bottom can snap in described inner chamber.
In use, the bottom of upper springs can be inserted in the top inner chamber of lower springs, thereby two or more helical springs are interconnected, change the length of spring.So just, without the helical spring according to concrete application customization given length, saved cost, and shortened the cycle.
Further, the outer circumferential face on described helical spring top is provided with screw thread, described helical spring bottom is provided with the cylinder that diameter is greater than described inner chamber internal diameter, and on described helical spring, cover has the nut that can screw in described screw thread, and a side of described nut is provided with the fixture block of convex.After the bottom of upper springs being inserted in the top inner chamber of lower springs, the nut of upper springs can be screwed in to the screw thread on lower springs top, the convex fixture block of this nut just can carry out the cylinder of upper springs spacingly like this, avoids two springs disengagings.
Adjustable length helical spring structure of the present utility model is simple, convenient to be made, and the mode that can connect by a plurality of springs changes length, applied widely.
The accompanying drawing explanation
Fig. 1 is adjustable length helical spring structural representation of the embodiment 1.
Embodiment
Below contrast accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and working principle etc.
Embodiment 1:
As shown in Figure 1, the top 7 of the adjustable length helical spring 1 of the present embodiment is provided with open lumen 2, and the bottom 8 of helical spring 1 all can snap in described inner chamber 2.
The outer circumferential face on the top 7 of helical spring 1 is equipped with screw thread 3, the bottom 8 of helical spring 1 is equipped with the cylinder 4 that diameter is greater than described inner chamber 2 internal diameters, on described helical spring 1, cover has the nut 5 that can screw in described screw thread 3, and a side of described nut 5 is provided with the fixture block 6 of convex.
In use, can be by the inner chamber 2 on the top 7 of the bottom of upper springs 8 insertion lower springs, the nut of upper springs 5 is screwed in to the screw thread 3 on lower springs top 7, the convex fixture block 6 of nut 5 just can carry out spacing to the cylinder 4 of upper springs like this, avoid two springs to break away from, thereby two helical springs are interconnected, change the entire length of spring.
After adopting the helical spring of the present embodiment, just, without the helical spring according to concrete application customization given length, saved cost, and shortened the cycle.

Claims (2)

1. an adjustable length helical spring, is characterized in that described helical spring top is provided with open lumen, and helical spring bottom can snap in described inner chamber.
2. adjustable length helical spring according to claim 1, the outer circumferential face that it is characterized in that described helical spring top is provided with screw thread, described helical spring bottom is provided with the cylinder that diameter is greater than described inner chamber internal diameter, on described helical spring, cover has the nut that can screw in described screw thread, and a side of described nut is provided with the fixture block of convex.
