Abstract

The utility model relates to a hardware fitting, name are centre has spring of mounting, including the spring body, the spring body in the middle of be provided with a rubber ring, the inboard of rubber ring is in spring body the inside, the inboard diameter of rubber ring is less than the diameter of spring body the inside, the rubber ring inboard blade that the interval set up still has, the free end of blade is the structure of attenuation, the inboard both sides of rubber ring have the arch, bellied free end be the structure of attenuation, the inside or periphery of rubber ring have the helical coiled passage who coils the spring, the spring can install to the swivelling movement in passageway the inside. Such spring has when the pressurized of both ends, the position is static relatively, the advantage of assurance result of use, still has the advantage that reduces the wearing and tearing between spring and the spindle.

Description

Centre has the spring of fixture

Technical field

This utility model relates to Hardware fitting, particularly relates to spring.

Background technology

Spring is the cylindrical structural of steel wire wound；In prior art, the centre of spring does not has positioning element, spring Be enclosed within arbor, often two ends interval pressurized, loosen, the middle parts not have to position, such spring will beat on axle, And the position on the length direction of axle is the most unstable, or there will be on the axle of spring the phenomenon along axe movement, so Spring can not be in relatively-stationary state, there is awkward shortcoming, also can cause the abrasion between spring and arbor.

Summary of the invention

The purpose of this utility model is aiming at disadvantages mentioned above, it is provided that a kind of when two ends pressurized, position is relatively fixed, makes With the spring in the middle of spring in good condition with fixture.

The technical solution of the utility model is achieved in that: centre has the spring of fixture, and including spring body, it is special Levy and be: being provided with a rubber ring in the middle of described spring body, the inner side of rubber ring is inside spring body, inside rubber ring Diameter less than the diameter inside spring body.

Saying also have spaced blade inside described rubber ring further, the free end of blade is thinning Structure.

Saying further, the described both sides inside rubber ring have projection, and described protruding free end is thinning Structure.

Saying further, there is the helical duct of coiled springs described rubber ring inside or periphery, and described spring is permissible It is arranged on inside passage in rotary movingly.

The beneficial effects of the utility model are: such spring has when two ends pressurized, position geo-stationary, ensure make By the advantage of effect, the advantage also with the abrasion reduced between spring and arbor；

Having spaced blade inside described rubber ring, the free end of blade is thinning structure, such spring May be mounted on the axle of different-diameter, there is the advantage that versatility is stronger；

The described both sides inside rubber ring have projection, and described protruding free end is thinning structure, and having can To be relatively securely fixed on axle, the advantage that less spring in use moves；

There is the helical duct of coiled springs described rubber ring inside or periphery, and described spring can be pacified in rotary movingly It is contained in inside passage, the advantage with the position that can adjust rubber ring on spring.

Wherein: 1, spring body 2, rubber ring 3, blade 4, projection.

Detailed description of the invention

The utility model will be further described below in conjunction with the accompanying drawings.

As it is shown in figure 1, centre has the spring of fixture, including spring body 1, it is characterized in that: described spring body Centre is provided with a rubber ring 2, and the inner side of rubber ring 2 is inside spring body, and the diameter inside rubber ring is less than spring originally Diameter inside body.

This sample spring housing is connected on axle, and spring does not contacts with axle, reduces the abrasion between spring and axle, additionally rubber ring May be also secured on axle, it is achieved the purpose of this utility model.

Saying also have spaced blade 3 inside described rubber ring further, the free end of blade is thinning Structure, as shown in Figure 1, 2, 3, is so fixed on axle due to blade, can be suitable for the axle of different-diameter in certain limit.

Saying further, the described both sides inside rubber ring have protruding 4, and described protruding free end is thinning Structure, as shown in Fig. 1,4,5, such rubber ring is fixed on axle more firm.

Saying further, there is the helical duct of coiled springs described rubber ring inside or periphery, and described spring is permissible It is arranged on inside passage, say, that rubber is not the structure being integrally forming being cast on spring, rubber ring in rotary movingly Can move on spring, in FIG, rubber ring can move up and down on spring, it is simple to adjusts rubber ring on spring Position relationship, uses more convenient.

The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model be not limited to this, Any those skilled in the art is in field of the present utility model, and change or the modification made all are contained of the present utility model In the scope of the claims.

Claims

1. there is in the middle of the spring of fixture, including spring body, it is characterized in that: in the middle of described spring body, be provided with one Rubber ring, the inner side of rubber ring is inside spring body, and the diameter inside rubber ring is less than the diameter inside spring body.

Spring the most according to claim 1, is characterized in that: also have spaced blade inside described rubber ring, The free end of blade is thinning structure.

Spring the most according to claim 1, is characterized in that: the described both sides inside rubber ring have projection, described Protruding free end is thinning structure.

4. according to the spring described in claim 1,2 or 3, it is characterized in that: described rubber ring is internal or there is coiled springs periphery Helical duct, described spring can be arranged on inside passage in rotary movingly.
