Description

Technical Field

[0001] The utility model relates to the technical field of water pump connectors, and particularly relates to a connector that can be quickly disassembled. Background Art

[0002] Generally, a water pump connector is arranged at the water outlet of the water pump to realize the connection between the water pump and an external device, solving the problem that the connection is troublesome due to the mismatch of the size, shape or thread at the interface between the water pump and the external device.

[0003] At present, the connection between water pump adapters is realized by using thread and buckle to connect the water pump and an external device. Both the installation in the early stage and the disassembly in the later stage are relatively troublesome. Especially when the thread is tightened too much, it will be very difficult to disassemble in the later stage. Content of the Utility Model

[0004] The utility model aims to provide a connector that can be quickly disassembled to overcome the deficiencies in the prior art.

[0005] To solve the above technical problems, the technical solution of the utility model is: a connector that can be quickly disassembled, including an elbow pipe and a straight pipe. The elbow pipe includes a first sealing head and a second sealing head. The first sealing head can be embedded into the straight pipe. An annular protrusion is arranged on the surface of the first sealing head. The straight pipe is provided with a connecting groove, and an installation opening is opened in the connecting groove. A buckle is also included. A protrusion is arranged on the inner surface of the buckle. The buckle is used to be installed on the connecting groove of the straight pipe. The protrusion of the buckle is embedded into the straight pipe through the installation opening, and the protrusion contacts the surface of the annular protrusion close to the elbow pipe.

[0006] In the above solution, first, the first sealing head of the elbow pipe is embedded into the straight pipe. The annular protrusion of the first sealing head is located at the front end of the installation opening of the straight pipe. Then, the buckle is installed at the connecting groove of the straight pipe. The protrusion of the buckle is embedded into the straight pipe through the installation opening, and the protrusion contacts the surface of the annular protrusion close to the elbow pipe, thereby realizing the installation between the elbow pipe and the straight pipe, solving the problem that the installation in the early stage and the disassembly in the later stage are troublesome due to the threaded connection between water pump adapters. Especially when the thread is tightened too much, it will be very difficult to disassemble in the later stage.

[0007] As an improvement of the connector that can be quickly disassembled of the utility model, a pressing end is arranged on the buckle, and the pressing end is pressed to move the protrusion away from the installation opening.

[0008] In the above solution, by pressing the two pressing ends of the buckle, the protrusion is disengaged from the installation opening, thereby releasing the fixation between the straight pipe and the elbow pipe, and then pulling out the elbow pipe from the straight pipe. Compared with the threaded fixation, it not only reduces the operation difficulty but also reduces the operation time.

[0009] As an improvement of a quick-disassembly joint of the present utility model, a sealing groove is provided on the first sealing head, and the sealing groove is equipped with a sealing ring.

[0010] In the above solution, in order to improve the sealing performance between the elbow pipe and the straight pipe, a sealing ring is installed on the sealing groove of the first sealing head, and the sealing ring is used for the sealing between the elbow pipe and the straight pipe.

[0011] As an improvement of a quick-disassembly joint of the present utility model, the straight pipe is provided with fan-shaped pieces, and a wedge block is arranged inside the fan-shaped pieces. The height of the wedge block gradually increases from the outer end to the inner end of the straight pipe. A connecting ring is arranged on the first sealing head, and the connecting ring contacts the wedge block of the fan-shaped piece.

[0012] In the above solution, when the first sealing head of the elbow pipe is inserted into the straight pipe, when the connecting ring of the first sealing head contacts the wedge block of the fan-shaped piece, it means that the first sealing head of the elbow pipe has reached the predetermined position inside the straight pipe, and then the protrusion of the buckle is installed inside the straight pipe.

[0013] As an improvement of a quick-disassembly joint of the present utility model, a groove for installing a sealing ring is provided at the tail end of the second sealing head.

[0014] In the above solution, a groove is provided at the tail end of the second sealing head, and the groove is equipped with a sealing ring, and the sealing ring is used to improve the sealing performance between the water pump and the joint.

[0015] As an improvement of a quick-disassembly joint of the present utility model, a plurality of threaded mounting ends are provided at the front end of the straight pipe, and the outer diameter of the threaded mounting ends becomes larger from the front end to the rear end of the straight pipe.

[0016] In the above solution, threaded mounting ends with different outer diameters are provided at the front end of the straight pipe to be used for adapting to water pipe connection joints with different inner diameters.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: The annular protrusion of the first sealing head is located at the front end of the installation opening of the straight pipe. Then, the buckle is installed at the connection groove of the straight pipe, and the protrusion of the buckle is embedded into the straight pipe through the installation opening. The protrusion contacts the surface of the annular protrusion on the side close to the elbow, thereby realizing the installation between the elbow and the straight pipe, and solving the problems that the installation and disassembly of the water pump adapter are troublesome due to threaded connection in the early stage. Especially when the thread is tightened too much, it will be very difficult to disassemble in the later stage. By pressing the two pressing ends of the buckle to disengage the protrusion from the installation opening, the fixation between the straight pipe and the elbow is released, and then the elbow is pulled out of the straight pipe. Compared with threaded fixation, it not only reduces the operation difficulty but also reduces the operation time. By pressing the two pressing ends of the buckle to disengage the protrusion from the installation opening, the fixation between the straight pipe and the elbow is released, and then the elbow is pulled out of the straight pipe. Compared with threaded fixation, it not only reduces the operation difficulty but also reduces the operation time. BRIEF DESCRIPTION OF THE DRAWINGS
