Abstract
The invention relates to a looseness-resistant elastic sheet which comprises an elastic sheet body of a board-shaped structure. A through hole is formed in the center of the body. A shaft sleeve is fixedly connected with the lower surface of the body. The size of a center hole of the shaft sleeve is identical to that of the through hole of the body. The two ends of the body are symmetrically bent downwards so that elastic ends can be formed. An elastic space is formed between the elastic ends. Compared with an existing elastic sheet nut, the looseness-resistant elastic sheet enables the elastic ends to be symmetrically arranged on the body, the size of the elastic space is changed through even deformation, so that large pre-tightening force is offered to a screw, and the shearing force and the bending moment exerted on the screw are small. The looseness-resistant elastic sheet has the advantages of being simple in structure, long in service life, high in connection stability and convenient to machine.
Description
Technical field
The present invention relates to pad, relate in particular to resilient pad.
Background technique
Locking shell fragment is the part that prevents that the fastening pieces such as screw or nut are loosening.Generally with the structure of annular opening, its shortcoming is the force unbalance that is subjected to that makes between screw bolt and nut to existing locking shell fragment, causes the steadiness that connects poor.
Summary of the invention
The applicant studies and improves for the above-mentioned shortcoming of prior art, provides a kind of simple in structure, the locking shell fragment that improve the screw force-bearing situation, increases the service life.
The technical solution adopted in the present invention is as follows:
A kind of locking shell fragment comprises the elastic sheet body of platy structure, and the center of body is with through hole, the affixed axle sleeve of the lower surface of body, the in the same size of the center hole of axle sleeve and the through hole of body; The two ends of body symmetrical downward bending forming elastic end forms elastic space between the elastic tip.
Beneficial effect of the present invention is as follows:
The more existing nut with elastic of the present invention, because elastic tip is symmetrically distributed on the body, it changes the size of elastic space by uniform deformation, offer the larger pretightening force of screw, its shearing force and moment of flexure to screw is less, it has simple in structure, long service life, the characteristics that stable connection is high and easy to process.
Description of drawings
Fig. 1 is three-dimensional structure diagram of the present invention.
Fig. 2 is main sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 1 and Fig. 2, the present invention includes the elastic sheet body 1 of platy structure, the center of body 1 is with through hole 11, the affixed axle sleeve 2 of the lower surface of body 1, the center hole 21 of axle sleeve 2 and the in the same size of the through hole 1 of body; The two ends of body 1 symmetrical downward bending forming elastic end 12 forms elastic space 3 between the elastic tip 12, elastic space 3 changes size along with the distortion of elastic tip 12.
The present invention in use, the bolt (not shown) is connected with connected piece after passing through hole 11 and elastic space 3, because elastic tip 12 is symmetrically distributed on the body 1, its distortion is even, and the elastic force of its generation has improved bolted reliability, simultaneously can avoid shell fragment that bolt is produced shearing force, improve the force-bearing situation of bolt, it has simple in structure, and is easy to process, long service life, the characteristics of stable connection.
Above description is explanation of the invention, is not that limited range of the present invention is referring to claim, in the situation that without prejudice to spirit of the present invention, the present invention can do any type of modification to the restriction of invention.
Claims (1)
1. locking shell fragment, the elastic sheet body (1) that comprises platy structure, it is characterized in that: the center of described body (1) is with through hole (11), the affixed axle sleeve of lower surface (2) of body (1), the in the same size of the center hole (21) of described axle sleeve (2) and the through hole (1) of described body; The symmetrical downward bending forming elastic end (12) in the two ends of described body (1) forms elastic space (3) between the described elastic tip (12).
