FIG. 2 is an enlarged view of the structure A of FIG. 1;
fig. 3 is a front view of the present invention.
In the figure: 1. a left ring body; 11. a right ring body; 2. a rubber sleeve; 21. a rubber ring; 22. a protrusion; 23. a clamping groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1 to 3, the present invention provides a technical solution of a self-sealing connector: a self-sealing connecting piece comprises a left ring body 1, a right ring body 11 connected with the left ring body 1 and an airtight mechanism arranged between the left ring body 1 and the right ring body 11. The airtight mechanism generates air flow to realize sealing by rotating, which is the prior art and is not detailed.
Still shelter from the mechanism including the elasticity that sets up between left ring body 1 and right ring body 11, shelter from the gap outside that the mechanism is located between left ring body 1 and the right ring body 11 in order to avoid the dust to get into. The right end of the rubber sleeve 2 extends rightwards to form a rubber ring 21 sleeved on the right ring body 11. The rubber ring 21 is convenient for fixing the rubber sleeve 2, and it should be noted that the rubber sleeve 2 only abuts against the left ring body 1, and the rubber sleeve can be contacted with the left ring body without much pressure, and a slight gap can be formed. The shielding mechanism comprises an annular rubber sleeve 2 arranged on the outer side of a gap between the left ring body 1 and the right ring body 11, the cross section of the rubber sleeve 2 is in the shape of an outward convex arc, the right end of the rubber sleeve 2 is arranged on the right ring body 11, and the left end of the rubber sleeve 2 abuts against the left ring body 1 to shield dust. The rubber sleeve 2 shields the dust on the outer side, and the dust is prevented from entering between the left ring body 1 and the right ring body 11, so that abrasion between the left ring body and the right ring body is avoided. The right end of the rubber sleeve 2 extends rightwards to form a rubber ring 21 sleeved on the right ring body 11, and the rubber ring is conveniently arranged on the right ring body 11.
The rubber ring structure further comprises a friction mechanism arranged between the rubber ring 21 and the right ring body 11, and the rubber ring 21 can be limited to slide left and right through the friction mechanism. Increasing friction and avoiding sliding. The friction mechanism comprises a circular arc-shaped bulge 22 formed by inward projection of the inner wall of the rubber ring 21, and a clamping groove 23 corresponding to the bulge 22 is formed in the right ring body 11. The locking groove 23 limits the protrusion 22 from sliding left and right to increase the friction force, and the elastic rubber ring 21 can be used for sleeving when the elastic rubber ring is installed.
The working principle is as follows: the rubber sleeve 2 is sleeved outside the gap between the left ring body 1 and the right ring body 11, and shields the dust on the outer side, so that the dust is prevented from falling into the gap, cleanness between the left ring body 1 and the right ring body 11 is guaranteed, and the service life is prolonged. The rubber sleeve 2 is arranged on the right ring body 11 through the rubber ring 21, and meanwhile, friction force is increased due to the arrangement of the protrusions 22 and the clamping grooves 23, and installation and fixation are facilitated.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
