Abstract
The invention relates to hardware fittings, in particular to a spring with a fixed piece in the middle. The spring comprises a spring body. A rubber ring is arranged in the middle of the spring body. The inner side of the rubber ring is located in the spring body. The diameter of the inner side of the rubber ring is smaller than that of the interior of the spring body. The inner side of the rubber ring is further provided with blades arranged at intervals. The free end of each blade is of a thinned structure. Protrusions are arranged on the two sides of the inner side of the rubber ring, and the free end of each protrusion is of a thinned structure. A screw channel wound around the spring is arranged in the rubber ring or on the periphery of the rubber ring, and the spring can be rotationally and movably mounted in the channel. The spring has the beneficial effects that when the two ends are pressed, the positions are relatively fixed, and the use effect is guaranteed, and the spring further has the beneficial effect that abrasion between the spring and a machine shaft is reduced.
Description
Technical field
The present invention relates to Hardware fitting, particularly relate to spring.
Background technology
Spring is the cylindrical structural of steel wire wound; In prior art, the centre of spring does not have positioning element, spring housing is on arbor, often two ends interval pressurized, loosen, the middle parts not have to position, such spring will be beated on axle and position on the length direction of axle is also unstable, or there will be the phenomenon along axe movement on the axle of spring, such spring can not be in relatively-stationary state, has awkward shortcoming, also can cause the abrasion between spring and arbor.
Summary of the invention
The purpose of the present invention is aiming at disadvantages mentioned above, it is provided that a kind of when two ends pressurized, position is relatively fixed, uses the spring in the middle of spring in good condition with fixture.
Technical scheme is achieved in that: centre has the spring of fixture, including spring body, it is characterized in that: be provided with a rubber ring in the middle of described spring body, the inner side of rubber ring is inside spring body, and the diameter inside rubber ring is 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 can be arranged on inside passage in rotary movingly.
The invention has the beneficial effects as follows: such spring has when two ends pressurized, the advantage of position geo-stationary, guarantee result of use, 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, and such spring may be mounted on the axle of different-diameter, has the advantage that versatility is stronger;
The described both sides inside rubber ring have projection, and described protruding free end is thinning structure, has and can relatively securely be 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 arranged on inside passage in rotary movingly, the advantage with the position that can adjust rubber ring on spring.

Fig. 4 is the A A cross-sectional view of another kind of situation in Fig. 1.
Fig. 5 is the C C cross-sectional view in Fig. 4.
Wherein: 1, spring body 2, rubber ring 3, blade 4, protruding.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As it is shown in figure 1, centre has the spring of fixture, including spring body 1, it is characterized in that: be provided with a rubber ring 2 in the middle of described spring body, the inner side of rubber ring 2 is inside spring body, and the diameter inside rubber ring is less than the diameter inside spring body.
This sample spring housing is connected on axle, and spring does not contact with axle, reduces the abrasion between spring and axle, and additionally rubber ring may be also secured on axle, it is achieved the purpose of the present invention.
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, so owing to blade is fixed on axle, it is possible to the axle of different-diameter in applicable certain limit.
Saying further, the described both sides inside rubber ring have protruding 4, and described protruding free end is thinning structure, and as shown in Fig. 1,4,5, it is more firm that such rubber ring is fixed on axle.
Say further, there is the helical duct of coiled springs described rubber ring inside or periphery, described spring can be arranged on inside passage in rotary movingly, it is to say, rubber is not the structure being integrally forming being cast on spring, rubber ring can move on spring, in FIG, rubber ring can move up and down on spring, it is simple to adjusts rubber ring position relationship on spring, uses more convenient.
The foregoing is only specific embodiments of the invention, but the architectural feature of the present invention is not limited to this, any those skilled in the art is in the field of the invention, and change or the modification made all are encompassed in the scope of the claims of the present invention.
Claims (4)
1. having the spring of fixture in the middle of, including spring body, it is characterized in that: be provided with a rubber ring in the middle of described spring body, the inner side of rubber ring is inside spring body, and the diameter inside rubber ring is less than the diameter inside spring body.
2. spring according to claim 1, is characterized in that: also have spaced blade inside described rubber ring, and the free end of blade is thinning structure.
3. spring according to claim 1, is characterized in that: the described both sides inside rubber ring have projection, and described protruding free end is thinning structure.
4. the spring according to claim 1,2 or 3, is characterized in that: there is the helical duct of coiled springs described rubber ring inside or periphery, and described spring can be arranged on inside passage in rotary movingly.
