Embodiment Construction

[0008] An embodiment of an elastic plug structure, in figure 1 Among them, the fixed sleeve body 2 is inserted with a telescopic plug 1, and the two ends of the telescopic plug 1 protrude from the two ends of the fixed sleeve body 2 respectively. The front end of the fixed sleeve body 2 has an inward-turned retaining edge 7, and the outer peripheral surface of the telescopic plug 1 is protruded with a collar 6, and the collar 6 is press-fitted with the retaining edge 7. A locking nut 4 is provided, and the rear end of the locking nut 4 has a turning edge, and the turning edge is press-fitted with the rear end surface of the fixed sleeve body 2 . The retractable head 1 is sleeved with a return spring 5, the front end of the return spring 5 presses on the collar 6, and the rear end of the return spring 5 presses on the turning edge.

[0009] A fixed convex ring 3 is arranged on the outer peripheral surface of the fixed sleeve body 2 , and there is a distance between the fixed c...

Abstract

The invention discloses an elastic plug structure. A flexible plug is inserted into a fixed sleeve body of the elastic plug structure; a blocking edge which is folded inwards is arranged on the inner end part of the fixed sleeve body; a shaft collar which is matched with the blocking edge in an ejecting pressing way is convexly arranged on the periphery of the flexible plug; a locknut is screwed on the rear end of the fixed sleeve body through threads; a flange which is matched with the rear end face of the fixed sleeve body in the ejecting pressing way is arranged on the rear end of the locknut; a reset spring is sleeved on the flexible plug; the front end of the reset spring is ejected and pressed on the shaft collar; and the rear end of the reset spring is ejected and pressed on the flange. The fixed sleeve body can be fixedly on one of two components which are in mutual slide match; a limit hole is formed in the other component; the flexible plug in the fixed sleeve can stretch into the limit hole so as to limit the two components; the flexible plug is longer and can stretch into the limit hole, so the positioning effect is good; the reset spring can provide force capable of keeping the flexible plug in a non-retractable state for the flexible plug; and the positioning of the elastic plug structure is reliable.

Description

technical field [0001] The invention relates to an elastic plug structure, which belongs to a mechanical positioning structure and can realize the positioning between two parts. Background technique [0002] The positioning between two parts is generally divided into fixed positioning structure and movable positioning structure. The fixed positioning structure is mainly bolts, while the movable positioning structure mainly includes pins. In some occasions where the two parts need to slide relatively, it is also necessary to be able to The positioning of the positioning structure is removed to facilitate the positioning of the contact positioning structure. One of the common structures in the prior art is that a blind hole is arranged on a component, and an upper spring is arranged in the blind hole. Set a steel ball on the top, the steel ball is on the spring, set a positioning hole for the steel ball to snap into the other part, the steel ball enters the positioning hol...
