Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

A first embodiment, referring to fig. 1 and 2, a hose connector with a sealing structure comprises a hose connector connected to an end of a hose, wherein the hose connector comprises a hollow external nut 1 and a hollow core 2, the core 2 has a pipe connection part 20, and the pipe connection part 20 is arranged through the external nut 1; the pipe connection part 20 is used for connecting a hose, and the external nut 1 is provided with an internal thread, so that the pneumatic device or other connecting pieces can be conveniently connected and disassembled.

In this embodiment, the pipe joint 20 includes a tapered connection port 22 (as shown in fig. 5), so that the pipe joint 20 can be pushed into the hose, and the connection with the hose is very convenient. In order to eliminate the assembly clearance between the pipe joint part 20 of the core 2 and the hose connection, the circumference of the pipe joint part 20 is provided with a limiting groove 21, and a sealing ring 24 is sleeved in the limiting groove 21, so that the clearance generated due to the improper assembly can be sealed, and the sealing performance of the connection between the pipe joint part 20 and the hose is enhanced. Preferably, the limiting groove 21 is defined by a ring of convex ring 23 arranged on the circumference of the pipe joint part 20, the convex ring 23 and the connecting port 22 define the limiting groove 21 together, and a sealing ring 24 is sleeved in the limiting groove 21, so that the sealing performance of the connection between the pipe joint part 20 and the hose is enhanced. A copper sleeve 3 is riveted on the outer side of the pipe joint part 20 of the core 2, and the end part of the hose is tightly pressed under the common acting force of the copper sleeve 3 and the pipe joint part 20. In order to further enhance the clamping force of the copper bush 3, a plurality of limiting ribs 30 are inwards pressed and formed on the circumferential surface of the copper bush 3, and the limiting ribs 30 are arranged along the length direction of the copper bush 3; because spacing muscle 30 is inwards protruding to be established, can further press from both sides the hose tight with the common effort of core 2 pipe joint portion 20 down, prevent that the hose from breaking away from, misplacing with core 2 pipe joint portion 20.

In order to further strengthen the clamping force of the copper bush 3, specifically, a plurality of rings of arch rings 31 are formed on the circumferential surface of the copper bush 3 in a pressing mode, the joint ends of the hoses are tightly pressed and arranged under the common acting force of the arch rings 31 and the limiting ribs 30, and the hoses are prevented from falling off and dislocating. In the present embodiment, the two arch rings 31 are provided, and are disposed in parallel on the surface of the copper bush 3.
