Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following detailed description is provided for the specific embodiments of the present invention.

Referring to fig. 1 to 6, a novel retractable protective plug provided in an embodiment of the present invention includes a housing 1 and a wiring module 2 disposed in one end of the housing 1, the side wall of the housing 1 is provided with anti-slip patterns 11 to play a role of anti-slip, one end of the housing 1 away from the wiring module 2 is sequentially provided with a middle sleeve 3 and a spring plate 4 disposed at an equal angle, and the spring plate 4, the middle sleeve 3 and the housing 1 are integrally disposed, so that the structure is relatively stable;

the rubber ring 5 is arranged on the inner side of the elastic sheet 4 in a contact mode, an inverted buckle 41 inclined inwards is arranged at one end, away from the middle sleeve 3, of the elastic sheet 4, the rubber ring 5 can be deformed by squeezing the elastic sheet 4, the inverted buckle 41 is in contact with the end portion of the rubber ring 5, the included angle between the inner side of the elastic sheet 4 and the inner side of the inverted buckle 41 is larger than 90 degrees, a chamfered angle 52 is formed at the position, right opposite to the connecting portion of the elastic sheet 4 and the inverted buckle 41, of the rubber ring 5, the inverted buckle 41 is deformed through the elastic sheet 4 and acts on the end portion of the rubber ring 5, and the connecting portion of the rubber ring 5 and the middle sleeve 3 is sealed;

an annular inserting part 51 is arranged at one end of the rubber ring 5, an annular inserting groove 31 matched with the annular inserting part 51 is arranged in the middle sleeve 3, the outer wall of the annular inserting part 51 is flush with the outer wall of the rubber ring 5, the thickness of the annular inserting part 51 is smaller than that of the rubber ring 5, a second chamfer 511 is arranged at the end part of the annular inserting part 51, and a third chamfer 33 used for guiding the annular inserting part 51 is arranged on the middle sleeve 3;
