Description

Technical Field

[0001] The invention relates to the technical field of pipe fitting connection, in particular to a quick plug-in connector structure. Background Art

[0002] In the prior art, there are various ways to connect pipe fittings, which are mainly divided into fixed connections and detachable movable connections: fixed connections include welding, bonding or hot melting, etc., but these connection methods are not conducive to disassembly and assembly; movable connection methods include threaded connection, clamping connection, sleeve connection, etc., which can be repeatedly disassembled and assembled, and are flexible and convenient to use. For example, they are often used to connect the hose between the water supply pipe and the water outlet terminal (such as faucet, shower, etc.).

[0003] Existing quick-plug connectors use elastic buckles to fix two connectors together. For example, a quick-plug connector disclosed in Patent No. CN209054222U movably connects the quick connector and the quick-connect body through an elastic pressing piece. However, after installation, the quick connector and the quick-connect body can rotate 360° relative to each other, which is easy to become loose, has poor stability and insufficient strength. Summary of the invention

[0004] The object of the present invention is to provide a quick plug-in / pull-out connector structure, which can realize directional quick plug-in / pull-out of parts, is easy to operate, and has higher product stability and strength.

[0005] In order to achieve the above object, the solution of the present invention is:

[0006] A quick plug-in connector structure, comprising a first connector with a plug, a second connector with a socket and a limiter; at least one protrusion is arranged on the outer periphery of the plug; a guide groove corresponding to the protrusion is arranged on the inner wall of the socket, a through hole is arranged at the bottom end of the guide groove to penetrate to the surface of the second connector, a notch is arranged on the side wall of the through hole to match the protrusion, a mounting groove matching the limiter is arranged on the surface of the second connector, and the end of the mounting groove is connected to the through hole; the limiter is provided with a limiter block matching the through hole; during installation, the protrusion is aligned with the guide groove to allow the plug to be inserted into the socket, and the first connector is rotated to allow the protrusion to be snapped into the notch, the limiter is buckled into the mounting groove to allow the limiter block to be snapped into the through hole, and the limiter block limits the protrusion from coming out of the notch, that is, limits the relative rotation of the first connector and the second connector.

[0007] The mounting groove is provided with a reset slope, and the reset slope is connected to the bottom of the mounting groove by the surface of the second connecting member, and is used to guide the limiting member to the direction of the through hole.

[0008] A pushing platform is arranged at the top end of the limiting block, and when the protrusion moves to the bottom end along the guiding groove, the protrusion will abut against the pushing platform.

[0009] The quick plug-in connector structure further comprises a sealing ring sleeved on the end of the plug, and when the plug is inserted into the jack, the sealing ring is tightly fitted between the plug and the jack.

[0010] Both ends of the position-limiting member are provided with buckling parts, and both ends of the installation groove are provided with buckling grooves. During installation, the buckling parts are buckled in the buckling grooves.

[0011] The mounting groove is an arc-shaped groove arranged around the axis of the second connecting member.

[0012] Two protrusions are arranged on the outer periphery of the plug, and the sizes of the two protrusions are different. The jack is correspondingly provided with two guide grooves respectively matching the sizes of the two protrusions.

DETAILED DESCRIPTION

[0024] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0025] The present invention is a quick plug-in connector structure, comprising a first connector 10 having a plug 11 , a second connector 20 having a socket 21 , and a stopper 30 .

[0026] At least one protrusion 111 is provided on the outer periphery of the plug 11;

[0027] The inner wall of the jack 21 is provided with a guide groove 211 corresponding to the protrusion 111, the bottom end of the guide groove 211 is provided with a through hole 212 to penetrate to the surface of the second connector 20, the side wall of the through hole 212 is provided with a notch 213 matching the protrusion 111, the surface of the second connector 20 is provided with a mounting groove 22 matching the stopper 30, and the end of the mounting groove 22 is connected to the through hole 212;

[0028] The limiting member 30 is provided with a limiting block 31 matching the through hole 212;

[0029] During installation, the protrusion 111 is aligned with the guide groove 211 so that the plug 11 is inserted into the jack 21, and the first connecting member 10 is rotated so that the protrusion 111 is inserted into the notch 213, and the limiting member 30 is buckled into the installation groove 22 so that the limiting block 31 is inserted into the through hole 212. The limiting block 31 limits the protrusion 111 from escaping from the notch 213, that is, limits the relative rotation of the first connecting member 10 and the second connecting member 20.

[0030] refer to Figures 1 to 7 Shown is a specific embodiment of the present invention.

[0031] The above-mentioned installation groove 22 is provided with a reset slope 221, which is connected from the surface of the second connecting member 20 to the bottom of the installation groove 22, and is used to guide the limit member 30 to the direction of the through hole 212. After the reset slope 221 is provided, the limit member 30 can be first inserted into the installation groove 22 during installation, and the limit block 31 can be inserted into the through hole 212. When the plug 11 of the first connecting member 10 is inserted, the protrusion 111 will push the limit block 31 out of the through hole 212, that is, push the limit member 30 to move along the reset slope 221 so that the limit member 30 expands and deforms outward. When the protrusion 111 is inserted into the notch 213, the limit member 30 returns to its original state and resets along the reset slope 221, so that the limit block 31 is inserted into the through hole 212 again. After that, the limit block 31 limits the movement of the protrusion 111 to prevent it from being separated from the notch 213, and the user's operation will be more convenient.

[0032] A pushing platform 311 is disposed at the top of the limiting block 31 . When the protrusion 111 moves to the bottom along the guide groove 211 , the protrusion 111 abuts against the pushing platform 311 , thereby pushing the limiting block 31 out of the through hole 212 .

[0033] The present invention further comprises a sealing ring 40 sleeved on the end of the plug 11. When the plug 11 is inserted into the jack 21, the sealing ring 40 is tightly fitted between the plug 11 and the jack 21 to achieve dynamic sealing and ensure the sealing performance of the product.

[0034] Both ends of the above-mentioned limit member 30 are provided with buckling parts 32, and both ends of the installation groove 22 are provided with buckling grooves 222. During installation, the buckling parts 32 are buckled in the buckling grooves 222 to ensure that the limit member 30 can be firmly buckled into the installation groove 22.

[0035] The mounting groove 22 is an arc-shaped groove arranged around the axis of the second connecting member 20 .

[0036] In this embodiment, two protrusions 111 are provided on the outer periphery of the plug 11, and the sizes of the two protrusions 111 are different. Therefore, the socket 21 is correspondingly provided with two guide grooves 211 that match the sizes of the two protrusions 111 respectively. When the two connectors are docked, the large protrusion 111 needs to be aligned with the large guide groove 211, and the small protrusion 111' needs to be aligned with the small guide groove 211' to achieve directional connection, which serves as a fool-proof structure and is more convenient for users to install.

[0037] In practical applications, both the first connecting member 10 and the second connecting member 20 can be connected to the pipeline 50 for circulating water.

[0038] refer to Figure 8 As shown, the disassembly and assembly process of the present invention is:

[0039] During installation, first insert the stopper 30 into the installation groove 22 so that the stopper block 31 fits in the position of the through hole 212; then align the protrusion 111 of the first connector 10 with the guide groove 211 of the second connector 20 and insert it and then rotate it clockwise. When the plug 11 is inserted into the jack 21, the protrusion 111 will abut against the pushing platform 311 to push the stopper block 31 of the stopper 30 downward. Since the stopper 30 is a disconnected ring, the stopper 30 is pushed downward along the reset slope 221. After the plug 11 rotates clockwise, the protrusion 111 rotates and inserts into the notch 213. The reset slope 221 will push the lower end of the stopper 30 upward to return the stopper 30 to the starting position. At this time, the plug 11 is hung in the notch 213 of the jack 21 through the protrusion 111, and the stopper block 31 can prevent the first connector 10 from reversing counterclockwise, so that the first connector 10 and the second connector 20 are relatively fixed.

[0040] During disassembly, the limiting member 30 is pressed downward to make the limiting block 31 lower than the plane of the notch 213, and the first connecting member 10 is rotated to make the protrusion 111 return to the guide groove 211, so that the first connecting member 10 and the second connecting member 20 can be pulled apart to separate them.

[0041] Through the above scheme, the present invention realizes the quick and movable connection between the first connecting member 10 and the second connecting member 20 through the structure of the rotating buckle, and then the limiting member 30 is inserted into the installation groove 22 so that the limiting block 31 limits the movement of the protrusion 111, thereby limiting the reversal and escape of the first connecting member 10. Since the first connecting member 10 and the second connecting member 20 are directly connected, the product is stable, has higher strength, and is more convenient to operate.

[0042] In addition, a reset slope 221 is set in the installation groove 22, and the deformation of the limit member 30 after being pushed is used to realize the reset of the limit member 30 along the reset slope 221, which will make the user's operation more convenient and labor-saving; the large and small ends of the two protrusions 111 are set to realize the fool-proof design of the first connecting member 10 and the second connecting member 20, which is convenient for users to quickly find the installation direction and improve the installation efficiency.

[0043] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
