Description

Technical Field

[0001] This utility model relates to the technical field of rubber hose connectors, specifically a rubber hose connector with good sealing performance. Background Technology

[0002] Rubber hoses are pipes used for gas transportation. They are commonly used in gas welding, gas cutting, various gas shielded welding, plasma arc welding and cutting. Due to the limited length of rubber hoses, there is a problem when using rubber hoses that are not long enough. Therefore, a connector is needed to connect two rubber hoses together so that the rubber hose can be used normally.

[0003] There is a rubber hose connector (CN202222186989.2) that allows for quick disassembly and assembly of the rubber hose by rotating the rotating sleeve clockwise when the rubber hose needs to be disassembled. This causes the L-shaped locking block to align with the disassembly / assembly groove, allowing the rubber hose to be removed from the inside of the splicing sleeve. This achieves a better and faster disassembly / assembly effect. However, it has shortcomings: the existing equipment has poor installation flexibility, poor installation stability and sealing, and is inconvenient to use. Therefore, a rubber hose connector with good sealing performance is needed to solve the above problems. Utility Model Content

The rubber tube 2 is installed at both ends of the connector fitting 1. The rubber tube 2 is installed in a supporting and sealing manner with the connector fitting 1 through the sealing gasket 8 and the splicing slot 9, so that the rubber tube 2 can be installed in a supporting and sealing manner, and the sealing effect is good.

[0022] The rubber hose 2 is screwed and clamped to the outer wall of the expansion locking block 5 by a locking threaded ring 3, and the expansion locking block 5 has a split structure, which allows the rubber hose 2 to be squeezed and clamped by the locking threaded ring 3 and the expansion locking block 5, resulting in stable installation and forming a double-layer seal with excellent effect. Locking threaded rings 3 are screwed and fitted onto both ends of the outer wall of the connector 1, and splicing slots 9 are opened at both ends of the inner wall of the connector 1. Sealing gaskets 8 are fixedly connected to the inner wall of the splicing slots 9. The rubber hose 2 is inserted into the splicing slots 9, and expansion locking blocks 8 are fixedly connected to both ends of the outer wall of the connector 1. The expansion locking block 5 and the fixing collar 4 are fitted and installed at the center of the outer wall of the connector pipe fitting 1. The lower end of the fixing collar 4 is fixedly connected to the folding groove 10, and the inner wall of the folding groove 10 is installed with the folding rotating block 11. The lower end of the folding rotating block 11 is fixedly connected to the guide rail 6, and the inner wall of the guide rail 6 is inserted and fitted with the lead screw 17. The guide rail 6 is rotatably connected to the connector pipe fitting 1 through the fixing collar 4, and the guide rail 6 and the clamping block 7 are folded and connected to the fixing collar 4 through the folding groove 10 and the folding rotating block 11.
