Abstract

It is a kind of that generate self-locking connection structure using retainer bias include: bolt, eccentric retainer, boss nut.Bolt, eccentric retainer internal diameter, boss nut axis are concentric, and the axle center decentraction of eccentric retainer outer diameter.It when bolt looseness, is limited by bolt hole, eccentric retainer outer diameter can not be played the role of clamping screw, be guaranteed switching performance by bolt axis rotation.

Description

It is a kind of to generate self-locking connection structure using retainer bias
Technical field
Self-locking connection structure is generated using retainer bias the present invention relates to a kind of.
Background technique
Currently, mainly using locking plate, self-locking nut or locking silk to the locking mode of bolt in engineering, prevent bolt from existing It is loosened in work.Although every kind of locking mode has their own advantages, but larger by effect of structural dimension, and not with structure design Disconnected development, existing locking mode have been unable to meet design requirement.
Summary of the invention
The purpose of the present invention is to solve above-mentioned shortcoming, to meet locking requirement of the bolt under special construction, such as The connection of aeroengine thrust augmentation cylinder and heat screen, and design and a kind of generate self-locking connection structure using retainer bias.
(1) technical problems to be solved
The present invention needs the locking effect for solving both to have guaranteed bolt, considers craftsmanship and economy again, while being easy to Assembly on product.
(2) technical solution
In order to solve the above-mentioned technical problem, the present invention is to be achieved through the following technical solutions:
1. a kind of, self-locking connection structure is generated using retainer bias includes: bolt (1), eccentric retainer (2), boss nut (3), connector 1 (4), connector 2 (5).
2. bolt (1) passes through eccentric retainer (2), and boss nut (3) connection.Eccentric retainer (2) not eccentric end to Bolt (1) head recess is symmetrically made a call to 2 and is rushed a little, and bolt (1) and eccentric retainer (2) are integrally formed.Aperture on connector 1 (4) 1,1 diameter of hole is identical as the eccentric outer diameter of retainer (2) eccentric end；Aperture 2 on connector 2 (5), 2 diameter of hole and boss nut (3) Outer diameter it is identical, and boss nut (3) is welded on connector 2 (5).
3. the inside and outside diameter decentraction of eccentric retainer (2) eccentric end, internal diameter and bolt (1), hole 2 and boss nut (3) are same The heart, axle center A, outer diameter and hole 1 are concentric, axle center B.When bolt (1) has loosening trend, due to eccentric retainer (2) eccentric end Inside and outside diameter decentraction, outer diameter restricted by hole 1, can not rotate by internal diameter axle center A, play the role of locking.
The beneficial effects of the present invention are:
1. structure is simple, craftsmanship and better economy, there is the meaning promoted in homogeneous structure.
2. as aeroengine thrust augmentation cylinder etc. can not or be not suitable for locking using locking plate, self-locking nut or locking silk Position, structural advantage are obvious.
3. eccentric retainer repeats dismounting and uses, better than locking plate and locking silk in economy using 2 punching point locking modes Etc. the locking mechanism that can not be reused.

Specific embodiment
The present invention is further described below by specific embodiment.
As shown in Figure 2: a kind of to generate self-locking connection structure using retainer bias include: 1, bolt；2, eccentric retainer； 3, boss nut；4, connector 1；5, connector 2.Bolt (1) passes through the hole on eccentric retainer (2) and connector 1 (4), with weldering Connect boss nut (3) connection on connector 2 (5).2 are symmetrically made a call to bolt (1) head on eccentric retainer (2) to rush a little (Fig. 2 arrow meaning position) locking.
Bolt (1), eccentric retainer (2) internal diameter, boss nut (3) axis are concentric (axle center A), and eccentric retainer (2) is eccentric Hold the axle center B decentraction of outer diameter.When bolt (1) loosens, limited by hole 1 on connector 1 (4), eccentric retainer (2) eccentric end Outer diameter can not be rotated by axle center A, played the role of clamping screw, guaranteed switching performance.
The features of the present invention:
1. nut can not be assembled by solving 2 side of connector using the structure by boss nut-welding on connector 2 Problem.
2. the eccentric retainer using internal-and external diameter decentraction is produced from lock ability.

Claims (1)
