Detailed Description
The utility model will now be further described with reference to the accompanying description and examples:
referring to fig. 1-3, a plug includes: top cap 1, support column 2, the tight structure 3 that expands, seal structure 4, 2 one end of support column with top cap 1 connect, the other end with the tight structure 3 that expands connect, the tight structure 3 that expands keep away from support column 2 one end with seal structure 4 swing joint.
The sealing structure 4 is a sealing rubber head which is surrounded and fixed on the inclined plane sealing structure by a plurality of cantilevers to form a hollow cavity.
The cantilever keep away from the one end of the sealed column structure in inclined plane is provided with outer protruding clamping structure 5, outer protruding clamping structure 5 on be provided with inclined plane guide structure 7, outer protruding clamping structure 5 be located the cavity outside.
The top of the sealing rubber head is provided with a break-proof ring 8, and the break-proof ring 8 is connected with the cantilever.
An inner convex clamping structure 6 is arranged at one end, far away from the inclined plane sealing structure, of the cantilever, and the inner convex clamping structure 6 is located inside the hollow cavity.
The inclined plane sealing structure is a conical column with a sloping surface.
The top cover 1 is arranged into a cylinder with the diameter larger than that of the bevel seal-shaped structure.
The support column 2 is connected one end of the expansion structure 3 is provided with a slope.
The expansion structure 3 is a conical column.
The first embodiment is as follows:
as shown in fig. 1: a rubber plug comprising: top cap 1, support column 2, the tight structure 3 that expands, seal structure 4, 2 one end of support column with top cap 1 connect, the other end with the tight structure 3 that expands connect, the tight structure 3 that expands keep away from support column 2 one end with seal structure 4 swing joint.
The sealing structure 4 is a sealing rubber head which is surrounded and fixed on the inclined plane sealing structure by a plurality of cantilevers to form a hollow cavity.
The cantilever keep away from the one end of the sealed column structure in inclined plane is provided with outer protruding clamping structure 5, outer protruding clamping structure 5 on be provided with inclined plane guide structure 7, outer protruding clamping structure 5 be located the cavity outside.
