Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a quick-connect structure for preventing water leakage. Background Art

[0002] Quick connectors are widely used in pipe connections for faucets, filters or water purifiers. They not only have the function of quickly connecting the hose to the above products, but are also very convenient when disassembling. At present, the quick-connect structure on the market generally includes a socket and a plug connector. The plug connector is installed in the socket. When installing, just insert the end of the hose into the socket and connect it to the above plug connector. Quick connectors bring great convenience to pipeline installation. However, in many cases, after the hose extends out of the quick connector, it bends and extends at a large angle. At this time, the end of the hose in the quick-release head will generate a large force to restore the deformation, which will squeeze the fitting wall or sealing structure of the end of the hose, causing deformation inside the quick-release head or the sealing structure, and then causing problems such as loose sealing and water leakage. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a quick-connect structure which can effectively prevent water leakage.

[0004] A quick-connect structure for preventing water leakage comprises a quick-connect body and a straightening seat, wherein:

[0005] One end of the quick-connect body is a plug-in end, which is provided with a plug-in interface for the end of the hose to be inserted and installed.

[0006] The straightening seat is arranged outside the quick-connect body and is provided with a straightening hole, and the straightening hole is in the extending direction of the plug interface.

[0007] When in use, the hose is inserted into the straightening hole and the plug interface in turn. At this time, under the action of the straightening hole, the hose is straight at a position close to the plug interface, and the end of the straightening hole replaces the plug interface to withstand the deformation recovery force that may be caused by the bending of the hose, thereby avoiding the possibility of deformation or damage to the sealing at the docking position between the quick-connect body and the hose, thereby effectively preventing the quick-connect structure from leaking.

[0008] Preferably, the straightening seat is docked at the plug-in end of the quick-connect body.

[0009] Preferably, the straightening seat and the plug-in end of the quick-connect body are spaced apart and connected by ribs. On the one hand, the distance between the bending part of the hose and the quick-connect body is increased as much as possible to reduce the influence of the force generated by the bending of the hose on the quick-connect body. On the other hand, the plug-in end of the quick-connect body is freed to reduce interference and influence on the quick disassembly and assembly of the hose.

[0010] Preferably, there are two ribs, which are symmetrically arranged about the central axis of the quick-connect body, and a disassembly operation opening is formed between the two ribs, so as to expose the plug-in end of the quick-connect body as much as possible.

[0011] Preferably, the quick-connect body includes a shell and a quick-install core, and the end of the hose is inserted into the plug port and docked with the quick-install core. The shell and the straightening seat are integrally formed to reduce the number of parts and assembly steps, while improving the connection reliability between the quick-connect body and the straightening seat, and preventing the straightening seat from being broken by the hose at the assembly position.

[0012] Preferably, a mounting cavity is provided in the shell, and a clearance hole is provided on the side of the mounting cavity facing the plug-in end. The quick-release core is in the shape of a sleeve, with a compressible elastic opening at one end and an undercut at the outer periphery. The elastic opening is inserted into the clearance hole after being compressed and restored in the mounting cavity. A support ring is provided on the outer periphery of the other end of the quick-release core, and the diameter of the support ring is larger than the diameter of the clearance hole. The quick-release core is telescopically installed on the clearance hole. An inclined surface is provided on the peripheral wall of the mounting cavity near the clearance hole. When the quick-release core is pulled outward, the inclined surface compresses the elastic opening by squeezing the undercut, so that when the hose and the quick-release core have a tendency to be pulled out of the shell together, the quick-release core can further hold the hose tightly to prevent the hose from detaching from the quick-release body.

[0013] Preferably, the inner ring of the elastic opening is provided with a clamping protrusion to increase the limiting force on the hose.

[0014] Preferably, a docking port is provided at the other end of the quick-connect body, and the quick-connect body is assembled at the water-passing joint of the water-passing member through the docking port.

[0015] Preferably, the inner ring of the docking port is provided with threaded teeth.

[0016] Preferably, a rotating handle is provided at the end of the straightening seat.

[0017] From the above description of the utility model, it can be seen that the utility model has the following beneficial effects:

[0018] The quick-connect structure provided by the utility model, when in use, under the action of the straightening hole, the hose is in a straight line at a position close to the plug interface, and the end of the straightening hole replaces the plug interface to bear the deformation recovery force that may be caused by the bending of the hose, thereby avoiding the possibility of deformation or damage to the sealing at the docking position between the quick-connect body and the hose, thereby effectively preventing the quick-connect structure from leaking;

[0019] The straightening seat and the plug-in end of the quick-connect body are arranged at intervals and connected by ribs, which can not only increase the distance between the bending part of the hose and the quick-connect body, reduce the influence of the force generated by the bending of the hose on the quick-connect body, but also make room for the plug-in end of the quick-connect body, reducing interference and influence on the quick disassembly and assembly of the hose;

[0020] The quick-connect body includes a shell and a quick-install core, and the shell and the straightening seat are integrally formed, which reduces the number of parts and assembly steps, while improving the connection reliability between the quick-connect body and the straightening seat, and preventing the straightening seat from being broken by the hose at the assembly position;

[0021] The inner ring of the elastic opening is provided with a clamping protrusion to increase the limiting force on the hose;

[0022] A rotating handle is provided at the end of the straightening seat to facilitate the assembly of the quick-connect body and the water-passing piece. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0034] See also Figures 1 to 7 A quick-connect structure for preventing water leakage comprises a quick-connect body 1 and a straightening seat 2, wherein:

[0035] One end of the quick-connect body 1 is a plug end 111, which is provided with a plug port 121 for inserting and installing the end of the hose.

[0036] The straightening seat 2 is arranged outside the quick-connect body 1 and is provided with a straightening hole 21 . The straightening hole 21 is in the extending direction of the plug-in port 121 .

[0037] In this embodiment, the straightening seat 2 is docked with the plug-in end 111 of the quick-connect body 1. Preferably, the straightening seat 2 and the plug-in end 111 of the quick-connect body 1 are spaced apart and connected by ribs 22. On the one hand, the distance between the bending part of the hose and the quick-connect body 1 is increased as much as possible to reduce the influence of the force generated by the bending of the hose on the quick-connect body 1. On the other hand, the plug-in end 111 of the quick-connect body 1 is released to reduce interference and influence on the quick disassembly and assembly of the hose.

[0038] Specifically, there are two ribs 22 symmetrically arranged about the central axis of the quick-connect body 1 , and a disassembly operation opening is formed between the two ribs 22 , so as to expose the plug-in end 111 of the quick-connect body 1 as much as possible.

[0039] Based on the above embodiments, in one embodiment, the quick-connect body 1 includes a shell 11 and a quick-connect core 12, and the end of the hose is inserted into the plug port 121 and docked with the quick-connect core 12. The shell 11 and the straightening seat 2 are integrally formed, which reduces the number of parts and assembly steps, and improves the connection reliability between the quick-connect body 1 and the straightening seat 2, thereby preventing the straightening seat 2 from being broken by the hose at the assembly position.

[0040] In addition, the housing 11 is provided with an installation cavity 112, and a clearance hole 113 is provided on one side of the installation cavity 112 facing the plug-in end 111. The quick-release core 12 is in a sleeve shape, with a compressible elastic opening 122 at one end and an undercut 1221 at the outer periphery. The elastic opening 122 is inserted into the clearance hole 113 after being compressed and restored in the installation cavity 112. A support ring 123 is provided at the outer periphery of the other end of the quick-release core 12. The diameter of the support ring 123 is larger than the diameter of the clearance hole 113. The quick-release core 12 is telescopically installed on the clearance hole 113. The peripheral wall of the installation cavity 112 near the clearance hole 113 is provided with an inclined surface 114. When the quick-release core 12 is pulled outward, the inclined surface 114 compresses the elastic opening 122 by squeezing the undercut 1221, so that when the hose and the quick-release core 12 have a tendency to be pulled out of the housing 11, the quick-release core 12 can further hold the hose tightly to prevent the hose from being separated from the quick-release body. In another embodiment, the inner circle of the elastic opening 122 is provided with a holding protrusion 1222 to increase the limiting force on the hose.

[0041] In one embodiment, the other end of the quick-connect body 1 is provided with a docking port 115, and the quick-connect body 1 is assembled at the water-passing joint of the water-passing member 3 through the docking port 115. Preferably, the inner ring of the docking port 115 is provided with a screw thread, and the end of the straightening seat 2 is provided with a rotating handle 23.

[0042] When in use, the hose is inserted into the straightening hole 21 and the plug port 121 in sequence. At this time, under the action of the straightening hole 21, the hose is in a straight line at a position close to the plug port 121, and the end of the straightening hole 21 replaces the plug port 121 to withstand the deformation recovery force that may be caused by the bending of the hose, thereby avoiding the possibility of deformation or damage to the sealing at the docking position between the quick-connect body 1 and the hose, thereby effectively preventing the quick-connect structure from leaking.
