Sleeve convenient to connect

Abstract

A sleeve convenient to connect comprises a sleeve body, a hollow part is formed in the connecting end of the sleeve body in the connecting direction, threads connected with a fixing thread sleeve are arranged on the outer wall of the connecting end, and the outer wall of the connecting end is gradually thickened from the tail end of the connecting end to the sleeve body. The connecting pipe has the advantages that the V-shaped hollowed-out part and the outer wall of the gradually-thickened connecting end are gradually folded under the action of the fixing threaded sleeve and are tightly attached to the corresponding connecting pipe, and connection which is convenient and does not need to be operated by an external tool is achieved.

Description

Technical Field

[0001] The utility model relates to a sleeve which is convenient to connect. Background Art

[0002] The existing sleeve includes a sleeve body, which has a hollow opening on one side of its connecting end, and a first fixed tube wall and a second fixed tube wall with elasticity are provided in the hollow opening, the upper side wall of the first fixed tube wall is connected to the upper side of the hollow inner wall, the lower side wall of the second fixed tube wall is connected to the lower side of the hollow inner wall, a gap is provided between the first fixed tube wall and the second fixed tube wall, and locking protrusions for fixed connection are provided on the outer sides of the first fixed tube wall and the second fixed tube wall, which makes the connection inconvenient and requires additional tools to be carried. Utility Model Content

[0003] The utility model aims to solve the shortcomings in the prior art and provides a sleeve that is convenient for connection.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sleeve that is easy to connect, including a sleeve body, the sleeve body is hollowed out along the connection direction at its connecting end, the outer wall of the connecting end is provided with a thread connecting and fixing the screw sleeve, and the outer wall of the connecting end gradually thickens from the end of the connecting end toward the sleeve body.

[0005] Furthermore, the hollowing is a V-shaped hollowing that gradually decreases from the end of the connection end toward the sleeve body.

[0006] Furthermore, the sleeve body is a T-shaped sleeve, and the above-mentioned connecting ends are provided in both the horizontal section and the vertical section.

[0007] Furthermore, a reinforcing rib is provided between the two outer connecting ends of the T-shaped sleeve.

[0008] The beneficial effect of the utility model is that the outer wall of the V-shaped hollow and gradually thickened connection end is gradually closed under the action of the fixing screw sleeve and is tightly attached to the corresponding connection pipe, thereby realizing a convenient connection without the need for external tools.
