Embodiment Construction
[0008] An embodiment of an elastic plug structure, in figure 1 Among them, a telescopic plug 1 is inserted into the fixed sleeve body 2 , and both 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 a blocking edge 7 that is turned inward, and a collar 6 is protruded on the outer peripheral surface of the telescopic plug 1. The collar 6 is press-fitted with the blocking edge 7, and the rear end of the fixed sleeve body 2 is screwed 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 fixing sleeve body 2 . A return spring 5 is sleeved on the telescopic head 1, the front end of the return spring 5 is pressed against the collar 6, and the rear end of the return spring 5 is pressed against the flange.
[0009] A fixed convex ring 3 is provided on the outer peripheral surface of the fixed...

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, belonging to a mechanical positioning structure, which can realize the positioning between two components. Background technique [0002] The positioning between the two parts is generally divided into a fixed positioning structure and a movable positioning structure. The fixed positioning structure is mainly bolts, while the movable positioning structure mainly includes pins. The positioning of the positioning structure is removed to facilitate the positioning of the contact positioning structure. A common structure in the prior art is that a blind hole is arranged on a component, and an upper spring is arranged in the blind hole. Remove the last steel ball, the steel ball rests on the spring, and set a positioning hole for the steel ball on the other part. The steel ball can enter the positioning hole to realize the positioning of the two parts. The sliding force can make the steel ball come out of ...
