According to the automatic silicon steel sheet leveling machine of the transformer. It is rational in infrastructure simple, guaranteed not only that spring when the compression, can also make spring's elasticity maximize, it is not fragile in addition, reinforcing life.

Description

A kind of spring

Technical field

The utility model belong to component of machine field and in particular to be a kind of spring.

Background technology

Spring is the important component part in mechanical part, is widely used in machinery instrument, survey tool and mechanical movement In control, the spring of prior art exists in compression process, particularly during Fast Compression, due to pressure and spring Recovering between elastic force is counter force, leads to spring bending, thus leading to the recovery elastic force of spring to change direction, loses bullet The due effect of spring.

And existing patented technology（Patent No. CN201420014967.0）In, by a kind of spring, described spring includes bullet , it is characterised in that described spring body includes two sections of condensed sections and connects loose section of condensed section, described loose section right for spring body Should be provided with can the mutually sleeve of telescopic slide and inner sleeve, described inner sleeve stretches in sleeve, and the external diameter of described sleeve and inner sleeve is smaller In the internal diameter of spring body, described sleeve and inner sleeve are equipped with base, and described base is buckled in condensed section, and described spring silk wraps up One layer of resilient sleeve, described sleeve and inner sleeve is had to be one end sealing, the cylindrical shape of one end open, the openend of described inner sleeve is stretched into The openend of sleeve, is tightly connected between described sleeve and inner sleeve and solves the problems, such as spring stress bending lost its bounce, but There is spring and be unable to reach maximum elastic force and spring with sleeve connection built on the sand, the defect easily coming off because of stress.

Utility model content

For solving above-mentioned technical problem, the utility model provides a kind of recovery elastic force enabling to spring to maximize, and And do not allow caducous spring.

For achieving the above object, the technical solution adopted in the utility model is, a kind of spring, mainly by extension spring and pressure Contracting spring forms, and its structural feature is to be provided with connection ring between extension spring and compression spring, is provided with sleeve in connection ring, set One end even is provided with spacing hole to cylinder with connection ring, and spacing in the hole is connected with spacing preiection, and the sleeve other end is provided with the extension of radial direction Portion, the extension of radial direction is in annular, and the arc surface of the extension of connection ring and sleeve is equipped with the ring being adapted to extension spring The end face of the extension of shape groove, connection ring and sleeve is equipped with annular groove, and sleeve is provided with limit near extension one end position Position ring, extension spring is two, is connected with the cannelure of connection ring and the extension of sleeve respectively, compression spring is set in sleeve Outward, compression spring two ends are connected with the annular groove of connection ring and the end face of the extension of sleeve respectively.

As preferred version of the present utility model, the external diameter of sleeve is equal to the internal diameter of connection ring.

As preferred version of the present utility model, the external diameter of the extension of sleeve is equal to the external diameter of connection ring.

As preferred version of the present utility model, spacing hole is several, several spacing hole annular arrays sleeve be connected One end that ring connects.

As preferred version of the present utility model, spacing ring external diameter is more than connection ring internal diameter, and spacing ring external diameter is less than compression Spring diameter.

The beneficial effects of the utility model are：Rational in infrastructure simple, not only ensure that spring, in compression, does not bend Deformation is it is ensured that recover elastic force additionally it is possible to make the elastic force of spring maximize, and is hardly damaged, and strengthens service life, thus dropping Low cost.

Brief description

Fig. 1 is that this uses new structural representation；

Fig. 2 is sleeve planing surface schematic diagram of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawings explanation is further explained to the utility model, but is not limited only to the utility model.

As shown in Figure 1 to Figure 2, the utility model is connected with sleeve 2 using connection ring 1, and compression spring 3 is set in sleeve 2 Outward, due to the restriction of sleeve 2, when ensure that compression spring 3 is under pressure will not bending it is ensured that compression spring 3 The action direction of restoring force, and enable compression spring 3 to reach maximum recovery elastic force.

In the present embodiment, one end even is provided with spacing hole 4 to sleeve 2 with connection ring 1, is connected with limit convex in spacing hole 4 Play 5, sleeve 2 other end is provided with the extension 6 of radial direction, and the extension 6 of radial direction is in annular, the extension of connection ring 1 and sleeve 2 6 arc surface is equipped with the cannelure being adapted to extension spring, and the end face of the extension 6 of connection ring 1 and sleeve 2 is equipped with annular Groove, sleeve 2 is provided with spacing ring 7 near extension 6 one end position, and extension spring 8 is two, respectively with connection ring 1 and set The cannelure of the extension 6 of cylinder 2 connects, and compression spring 3 is set in outside sleeve 2, compression spring 3 two ends respectively with connection ring 1 and The annular groove of the end face of extension 6 of sleeve 2 connects, and ensure that being fastenedly connected between compression spring 3 and sleeve 2, prevents Anti-avulsion falls, and, compression spring 3 can be protected to avoid compression spring 3 to be subject to exceed the pressure of the elastic value that sets up, it is to avoid Compression spring 3 is damaged.
