Description

Elastic support ring

Technical Field

The utility model relates to an elastic support piece technical field, concretely relates to elastic support ring.

Background

At present, the spring washer can be used for pre-tightening in places needing pre-tightening force, the existing spring washer is generally in a circular ring shape, an inclined notch is formed in one side of the spring washer, two ends of the inclined notch of the spring washer tilt towards the direction away from each other, when the spring washer is used, the two ends of the spring washer tilt are flattened, the flattened elastic washer has elastic restoring force, the elastic washer has defects, sharp points exist at two ends of the tilt when the spring washer is not flattened, and hands of people can be hurt.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned technique not enough, provide an elastic support ring, there is the technical problem that the staff may be pricked to sharp-pointed point in the elastic washer among the solution prior art.

In order to achieve the technical purpose, the technical scheme of the utility model provide an elastic support ring, elastic support ring are annular tubulose and inside hollow, elastic support ring sets up the annular breach rather than inside being linked together, annular breach with the coaxial setting of elastic support ring, the annular breach is located elastic support ring keeps away from one side at center or is located elastic support ring is close to one side at center.

Compared with the prior art, the beneficial effects of the utility model include: the elastic support ring is clamped when pre-tightening is needed, the upper inner wall and the lower inner wall at the annular notch are mutually closed along with the clamping of the elastic support ring, when the force for clamping the elastic support ring is loosened, the annular notch of the elastic support ring is slowly reset, so that the elastic support ring has certain elasticity, can provide better elastic restoring force, can be used in places where elastic pre-tightening force needs to be applied, does not have sharp points, and cannot injure people.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The utility model provides an elastic support ring, as shown in fig. 1 to 5, elastic support ring 1 is annular body and inside hollow, and elastic support ring 1 sets up the annular breach 1a rather than inside being linked together, and annular breach 1a and the coaxial setting of elastic support ring 1, annular breach 1a are located elastic support ring 1 and keep away from one side at center or are located one side that elastic support ring 1 is close to the center.

Preferably, the annular gap 1a is located on the side of the elastic support ring 1 away from the center.

Any material has certain toughness, and when the elastic support ring 1 is compressed, the inner walls of the annular gaps 1a are close to each other, the elastic support ring 1 is compressed, and the elastic support ring 1 has reset elastic restoring force.

Preferably, the elastic support ring 1 is made of spring steel.

Set up to spring steel through the material with elasticity support ring 1 for elasticity support ring 1 has elastic deformation's ability and has better intensity.

Preferably, the elastic support ring 1 is made of a hollow tube with a C-shaped cross section.

The elastic support ring 1 is made of a hollow pipe body with a C-shaped section, and when the upper inner wall and the lower inner wall of the annular gap 1a are close to each other, the ring body part has better bending property and elasticity.

Preferably, the height of the annular gap 1a along the axial direction of the elastic support ring 1 is smaller than the inner diameter of the elastic support ring 1.

Through setting up annular breach 1a to be less than the internal diameter of elastic support ring 1 along the axial highly setting of elastic support ring 1, when avoiding annular breach 1a along the axial highly too big of elastic support ring 1, elastic support ring 1 avoids when pretension along the axial distance overlength that can deform, avoids fracturing or pressure break elastic support ring 1.

Further preferably, the height of the annular gap 1a in the axial direction of the elastic support ring 1 is half of the inner diameter of the elastic support ring 1.

When the height of the annular gap 1a along the axial direction of the elastic support ring 1 is too small, the deformable length of the elastic support ring 1 is too small, so that the elastic restoring force provided by the elastic support ring 1 is too small, and when the height of the annular gap 1a along the axial direction of the elastic support ring 1 is too large, the deformable distance of the elastic support ring 1 is too large, so that the deformable length of the elastic support ring 1 is too large, the elastic support ring 1 may be cracked during pre-tightening, therefore, the height of the annular gap 1a along the axial direction of the elastic support ring 1 is selected to be one half of the inner diameter of the elastic support ring 1, the two situations are avoided, and the elastic support ring 1 has proper elastic restoring force and better structural strength.

The utility model discloses a concrete work flow: through setting up elastic support ring 1, set up elastic support ring 1 in the place that needs applied the elasticity pretightning force, and press from both sides tight elastic support ring 1 when the pretension, along with elastic support ring 1 is pressed from both sides tightly, the upper and lower inner wall of annular breach 1a department draws close each other, when the power of pressing from both sides tight elastic support ring 1 takes place the relaxation, annular breach 1a department of elastic support ring 1 slowly resets, make elastic support ring 1 have certain elasticity, can provide better elastic restoring force, can be used for many places that need apply the elasticity pretightning force.

The above description of the present invention does not limit the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the scope of the claims of the present invention.
