Description

Technical fields:

[0001] This utility model relates to the field of sanitary ware technology, specifically a quick-connect toilet connection pipe. Background technology:

[0002] Currently, toilet connection pipes have a non-removable structure with nuts at both ends. The structural characteristics of toilets result in limited installation space for the connection pipes, and once the toilet is installed, installing the connection pipes is difficult, and replacing them later is even more difficult. Utility model content:

[0003] The technical problem to be solved by this utility model is to provide a quick-connect toilet hose, which has a simple structure and is easy to disassemble and assemble, and can solve the problem of difficulty in replacing and installing toilet hoses.

[0004] The technical solution of this utility model is to provide a quick-connect toilet connection pipe, including a connecting hose and a toilet water fitting connector for connecting with the toilet water fitting. One end of the connecting hose is provided with a hose quick connector. The hose quick connector and the toilet water fitting connector are separate structures and can be quickly connected by plugging. The other end of the connecting hose is provided with a water inlet connecting nut.

[0005] Preferably, the toilet water fitting connector includes a connecting pipe body. One end of the connecting pipe body, which is used to connect to the toilet water fitting, has an internal thread that connects with the toilet's connecting thread. The other end of the connecting pipe body has a groove on the pipe wall near the end that passes through the inner cavity.

[0006] Preferably, the inner cavity of the toilet flush connector between the internal thread and the groove has a stepped structure, wherein the diameter of the inner cavity near the internal thread end is smaller than the diameter of the inner cavity near the groove end.

[0007] Preferably, the end of the hose quick connector used to connect with the toilet fitting is a stepped connector, which is adapted to the inner cavity of the toilet fitting. The outer wall of the stepped connector is also provided with a hook that engages with the slot. When the toilet fitting and the hose quick connector are connected by a quick-connect plug, the toilet fitting and the hose quick connector align with each other along their axial direction and are positioned by the engagement of the slot and the hook.

[0008] Preferably, the stepped connector is also provided with a sealing groove on its circumferential surface, which is used to embed a sealing ring.

[0009] Preferably, the end of the quick-connect hose that connects to the hose is also provided with a sealing groove, which is used to embed a sealing ring.

[0010] Preferably, the outer surface of the quick-connect hose is also provided with a handle.

[0011] Furthermore, the toilet flush connectors and hose quick-connect fittings are made of plastic.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model has a simple structure and is easy to disassemble and assemble, which can solve the problem of difficult replacement and installation of toilet hoses. Attached image description:

[0014] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model.

[0015] Figure 2 This is a structural schematic diagram of the toilet water fitting connector according to an embodiment of the present utility model. Detailed implementation method:

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figure 1-2 As shown, a quick-connect toilet fitting includes a connecting hose 1 and a toilet fitting connector 9 for connecting to the toilet fitting. One end of the connecting hose 1 is provided with a hose quick connector 7. The hose quick connector 7 and the toilet fitting connector 9 are separate structures. The toilet fitting connector 9 and the hose quick connector 7 can be connected by mating along their axial directions to achieve a quick-connect plug-in connection. The other end of the connecting hose 1 is provided with an inlet end connecting nut 4, just like existing connecting hoses. The inlet end connecting nut 4 is connected to the inlet pipe. During processing, the inlet end connecting nut 4 is connected and fixed to the connecting hose 1 through the cooperation of the core 3 and the crimping steel seal 2. The inlet end connecting nut 4 is also provided with an inlet end sealing gasket 5.

[0018] In this embodiment, the toilet water fitting connector 9 includes a connecting pipe body. One end of the connecting pipe body, which is used to connect to the toilet water fitting, has an internal thread that connects with the toilet water fitting thread. The internal thread can be used to fix the toilet water fitting. The other end of the connecting pipe body has a groove that passes through the inner cavity on the pipe wall near the end.

[0019] In one embodiment, the inner cavity of the toilet water fitting connector 9 between the internal thread and the groove has a stepped structure, wherein the diameter of the inner cavity near the internal thread end is smaller than the diameter of the inner cavity near the groove end.

[0020] Correspondingly, the end of the quick-connect hose 7 used to connect with the toilet water fitting is also a stepped connector. The stepped connector is adapted to the inner cavity of the toilet water fitting 9. The outer wall of the stepped connector is also provided with a hook that engages with the slot. When the toilet water fitting 9 and the quick-connect hose 7 are connected by a quick-connect plug, the toilet water fitting 9 and the quick-connect hose 7 align with each other along their axial direction, so that the quick-connect hose 7 is inserted into the toilet water fitting 9 and rotated clockwise so that the hook is engaged in the slot of the toilet water fitting, ensuring that the quick-connect hose does not come out, enabling normal water use, and making installation quick and convenient.

[0021] In use, the toilet water fitting connector is first connected to the toilet water fitting. Since the toilet water fitting connector is small in size, it is convenient to install both. Then, the hose quick connector is inserted into the toilet water fitting connector for quick connection.

[0022] In one implementation, a sealing groove is also provided on the circumferential surface of the stepped connector, which is used to embed the sealing ring 8; the end of the hose quick connector 7 that connects to the connecting hose 1 is also provided with a sealing groove, which is used to embed the sealing ring. After the hose connector and the connecting hose are connected, they are secured with a steel sleeve 6.

[0023] In one embodiment, the outer surface of the quick-connect hose 7 is also provided with a hand-held part 71, which allows for easy disassembly and assembly.

[0024] In one implementation, the toilet flush connector 9 and the quick-connect hose 7 are made of plastic, and the connecting hose is also made of plastic. The quick-connect components are made of plastic, which is inexpensive, energy-efficient, and environmentally friendly.

[0025] The above description only illustrates preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. Any equivalent structural or procedural modifications made using this specification are included within the patent protection scope of this invention.
