[0026] See also Figure 1-6The utility model provides an embodiment: a quick-release connector, comprising a connector body 1, two slots 2 symmetrically arranged on the outer side wall of the connector body 1, and two limit plugs 3 respectively arranged on the opposite sides of the two slots 2, the connector body 1 is a cylindrical tubular structure, and the connector body 1 is a hard plastic tube, the openings of the two slots 2 are opposite, and the openings of the two slots 2 extend to the outside of the connector body 1 along the axial direction of the connector body 1, specifically, the slot 2 is a C-shaped structure, and a reinforcing rib 201 is arranged on the outer side wall of the slot 2 to improve the strength of the slot 2;

[0027] The limiting plug 3 is arranged on the outer wall of the joint body 1, and one end of the limiting plug 3 is flush with the end of the joint body 1, and the other end of the limiting plug 3 includes a connecting section 301, a limiting protrusion 302 and a guide section 303 connected end to end. The end of the limiting plug 3 close to the connecting section 301 is fixedly connected to the outer wall of the slot 2, and a gap is reserved between the end of the limiting plug 3 close to the guide section 303 and the other slot 2, and the width of the gap is greater than the width of the slot 2. Specifically, the limiting protrusion 302 extends to the end away from the opening of the joint body 1, and its thickness is greater than the thickness of the connecting section 301. The thickness of the guide section 303 gradually decreases from the limiting protrusion 302 to the other end. When the two quick-release connectors are used together, the end with a smaller thickness is first inserted into the interior of the slot 2, and then the joint body 1 is rotated for easy assembly;

[0028] The connecting section 301 matches the slot 2. When the two quick-release connectors are plugged in, the limiting plug 3 is inserted into the corresponding slot 2, and the limiting protrusion 302 abuts against the outer wall of the slot 2 for limiting. For details, please refer to Figure 4-5 When in use, first align the slot 2 of one quick-release connector with the slot 2 of another quick-release connector and the limiting plug 3, then rotate the connector body 1, and screw the connecting section 301 into the slot 2. At this time, the outer side walls on both sides of the slot 2 of the quick-release connector respectively abut between the limiting protrusion 302 of the other quick-release connector and the slot 2 to achieve positioning, avoid the quick-release connector from rotating during use, and make the connection more firm and reliable.

[0029] The end of the connector body 1 away from the slot 2 is provided with a connector 5, the connector 5 is a hose, and one end of the connector body 1 is provided with a plug tube 101, and the plug tube 101 is inserted into the interior of the connector 5 and fixedly connected to the connector 5. For details, please refer to Figure 6 The plug-in tube 101 is fixedly connected to the connector 5 by an annular clamp block and a clamping groove. By setting a hose, the installation and fixation of the quick-release connector is convenient. In the prior art, threads are generally set on the inner side wall of the connector body 1 to achieve the installation and fixation of the connector body 1. During production, threads need to be set on the connector body 1, which has a high production cost.

[0030] An elastic sealing ring 4 is arranged at one end of the joint body 1 close to the slot 2, which can not only improve the sealing performance of the connection between the two quick-release joints, but also has a certain elastic deformation force, so as to facilitate the disassembly and assembly of the quick-release joint.

[0031] A quick-disassembly structure for cleaning water pipes, please refer to Figure 7-8 , including a water pipe body 7, a water inlet pipe 6 and a sealing head 8 respectively arranged at both ends of the water pipe body 7, and a hook 10 for supporting the sealing head 8. The hook 10 is penetrated with a plug hole 1001 for accommodating the sealing head 8 to pass through. In this embodiment, the water pipe body 7 is a hollow tubular structure with two ends through, and a plurality of nozzles are arranged at the bottom end thereof. It can also be set to other shapes or structures. The opposite ends of the water inlet pipe 6 and the water pipe body 7 are detachably connected by a quick-release joint, and the two quick-release joints are divided by a clamp 9 The water inlet pipe 6 is fixedly connected to the end opposite to the water pipe body 7, and is used for the quick disassembly and assembly of the water pipe body 7 and the water inlet pipe 6. The water inlet pipe 6 is fixed on the cleaning equipment (not shown in the figure). The clamp 9 is a prior art and will not be described here. During installation, the connector 5 of the quick-release connector is respectively inserted into the water inlet pipe 6 and the water pipe body 7, and then the connector 5 is tied by the clamp 9, so that the connector 5 is tightly attached to the water inlet pipe 6 / water pipe body 7, which is convenient for disassembly and assembly. At the same time, the connector 5 is a hose, and the sealing performance of the connector is good;

[0032] See also Figure 8 The sealing head 8 includes a connecting hose 802 and a sealing cover 801 fixed to one end of the connecting hose 802. Specifically, the sealing cover 801 and the connecting hose 802 can be fixedly connected through a card block and a card slot. When in use, one end of the water pipe body 7 is inserted into the interior of the connecting hose 802, and its end abuts against the sealing cover 801. The sealing cover 801 is a hard plastic tube and plays a positioning role. Then, the connecting hose 802 is tightened and fixed by the clamp 9;

[0033] In this embodiment, the hook 10 includes a vertical section and a horizontal section arranged at the top of the vertical section, and a mounting hole is provided through the horizontal section to facilitate assembly on the cleaning equipment. The socket 1001 is provided on the vertical section. When in use, it is only necessary to insert the sealing head 8 into the socket 1001 to play a supporting role. It can also be set to other shapes as needed.

[0034] Working principle: When in use, the joint bodies 1 of the two quick-release joints are abutted against each other, and the slot 2 of one quick-release joint is inserted from the gap between the slot 2 of the other quick-release joint and the limiting plug 3. After the limiting plug 3 is aligned with the slot 2, the quick-release joint is rotated, and the guide section 303 is first screwed into the inside of the slot 2. An elastic sealing ring 4 is provided on the mating surface of the two joint bodies 1, which has a certain elastic deformation and is squeezed toward the middle. The joint is continuously rotated until the slot 2 is rotated to the outside of the guide section 303. After the fixation is completed, the outer walls on both sides of the slot 2 of the quick-release joint are respectively abutted between the limiting protrusion 302 of the other quick-release joint and the slot 2 to achieve positioning and avoid the quick-release joint from rotating during use. When disassembly is required, the elastic sealing ring 4 is squeezed toward the middle, and then the joint is rotated toward the side close to the limiting protrusion 302 to separate the slot 2 from the limiting plug 3 of the other quick-release joint.
