Abstract
The utility model discloses a threaded connection anti-loosening mechanism. The threaded connection anti-loosening mechanism is characterized by comprising a connection screw cap, a shell, a ball and a conical spring, wherein the shell is arranged inside the connection screw cap; one end of the conical spring is pushed against the ball and arranged in a small hole which is formed in the shell in the radial direction; and the position of the ball is correspondingly pushed against a position, which is provided with a saw-shaped anti-return groove, on the inner wall of the connection screw cap. The threaded connection anti-loosening mechanism of the utility model has a simple principle and structure, low manufacturing cost and wide market prospect, is convenient to use and is detachable.
Description
Technical field
The utility model relates to mechanical structure field, particularly a kind of thread connection anti-loose mechanism.
Background technique
In the mechanical whorl link, be threaded usually occur screwing after, in use owing to reasons such as vibrations, produce looseningly, locked Placement is not easy to dismounting again, presses for dismountable thread connection anti-loose device.
The model utility content
The purpose of this utility model is in order to realize the locking device of threaded connection detachable, and the spy provides a kind of thread connection anti-loose mechanism.
The utility model provides a kind of thread connection anti-loose mechanism, it is characterized in that: described thread connection anti-loose mechanism comprises coupling nut 1, housing 2, ball 3, volute spring 4;
Wherein: housing 2 is installed in the inside of coupling nut 1, and an end of volute spring 4 withstands ball 3, is installed in the aperture of housing 2 radial arrangement, and the position correspondence of ball 3 withstands on the position that has the zigzag fashion locking trough on the inwall of coupling nut 1.
Radial hole in the described housing 2 is 2 to 5, and is uniform.
The zigzag fashion locking trough number that has on the inwall of described coupling nut 1 is 14 to 40.
Since the zigzag fashion locking trough that has on the inwall of coupling nut 1, the angle of inclination difference of groove both sides, relatively easy in the time of can realizing threaded together under the cooperation of ball 3 and volute spring 4, harder when withdrawing from, realize locking by the elastic force of spring.
Advantage of the present utility model:
Thread connection anti-loose described in the utility model mechanism, theory structure is simple, and low cost of manufacture is easy to use, and is detachable, will have extensive market prospects.
Description of drawings
Below in conjunction with drawings and the embodiments the utility model is described in further detail:
Fig. 1 is a thread connection anti-loose mechanism overall schematic;
Fig. 2 is for having the sectional view at zigzag fashion locking trough position on the inwall of coupling nut.
Embodiment
Present embodiment provides a kind of thread connection anti-loose mechanism, it is characterized in that: described thread connection anti-loose mechanism comprises coupling nut 1, housing 2, ball 3, volute spring 4;
Wherein: housing 2 is installed in the inside of coupling nut 1, and an end of volute spring 4 withstands ball 3, is installed in the aperture of housing 2 radial arrangement, and the position correspondence of ball 3 withstands on the position that has the zigzag fashion locking trough on the inwall of coupling nut 1.
