Description

Technical Field

[0001] The utility model relates to the field of bathrooms, in particular to a pipe quick-connect structure and a pipe quick-connect assembly. Background Art

[0002] Among existing bathroom products, many products require connecting two pipes, which leads to many pipe connection solutions.

[0003] Chinese patent CN203847873U discloses a pipe connection structure, which can facilitate the connection of two pipes. However, the pipe connection structure has the following problems:

[0004] 1. The two elastic clips of the pipe connection structure are set separately, so that the two elastic clips need to avoid each other when they are installed into the socket and require the help of tools, which makes the installation of the two elastic clips inconvenient;

[0005] 2. The pipe connection structure uses the elastic clip of the elastic clip to reset the elastic clip. In this way, a retaining wall needs to be set inside the socket for the elastic clip to abut, which makes the socket structure complicated. At the same time, it also makes the overall volume of the pipe connection structure large, which is not convenient to be set in a place with a small space.

[0006] Chinese patent CN210196730U discloses a pipe connection structure, which connects two pipes through a limiter. However, the pipe connection structure has the following problems:

[0007] The limiting piece of the connection structure of the pipe fitting does not limit the side of the limiting piece, which causes the connection structure of the pipe fitting to be easily disengaged when subjected to strong force, resulting in an unstable connection problem.

[0008] In view of the existence of the above problems, it is necessary to study a pipe quick-connect structure and a pipe quick-connect assembly, which has the advantages of easy assembly and stable connection with the male joint. Utility Model Content

[0009] The purpose of the utility model is to provide a pipe quick-connect structure and a pipe quick-connect assembly, which have the advantages of easy assembly and stable connection with a male joint.

[0010] In order to achieve the above objectives, the solution of the present invention is:

[0011] A pipe quick-connect assembly, which is used to connect with a male connector, and the male connector is provided with a connecting head; the pipe quick-connect assembly includes a female connector and a limit member; the female connector is provided with a connecting channel for inserting the connecting head, and connecting through holes communicating with the connecting channel are respectively opened on both sides of the female connector; the limit member is installed in the female connector, and the limit member has two limiting clips and at least one elastic arm connecting the two limiting clips, and the two limiting clips are respectively slidably connected with the connecting through holes on both sides of the female connector, and the two limiting clips can move relative to each other to tighten or loosen the connecting head inserted into the connecting channel.

[0012] The limiting member has two elastic arms, two ends of one of the two elastic arms are respectively connected to the same side of the two limiting buckles, and two ends of the other of the two elastic arms are respectively connected to the other side of the two limiting buckles.

[0013] The elastic buckles and elastic arms of the limiting member are integrally arranged.

[0014] The elastic arm is arranged obliquely.

[0015] A mounting protrusion is provided on the outer side of at least one of the two limiting buckles of the limiting member; and a mounting hole connected to the mounting protrusion is provided on the side wall of the female connector.

[0016] The mounting protrusion is in sliding engagement with the mounting hole.

[0017] Both sides of the installation protrusion form installation inclined surfaces.

[0018] The outer wall of the connecting head is provided with a connecting ring groove; the limiting buckle is provided with an arm that cooperates with the connecting ring groove, and the inner side of the arm has an arc-shaped limiting bayonet and an avoidance bayonet, and the radius of the avoidance bayonet is larger than the radius of the limiting bayonet; when the elastic arm of the limiting member is extended, when the limiting bayonet holes of the two limiting buckles of the limiting member are opposite and snapped into the connecting ring groove of the connecting head; when the two limiting buckles of the limiting member are pressed to compress the elastic arm of the limiting member to the point that the avoidance bayonet holes of the two limiting buckles of the limiting member are opposite, the connecting head can freely pass through the avoidance channel formed by the avoidance bayonet holes of the two limiting buckles of the limiting member.

[0019] An insertion slope is provided on the same side of the arms of the two limiting buckles of the limiting member.

[0020] A pipe quick-connect structure includes a male connector and the pipe quick-connect assembly described above, wherein the male connector is provided with a connector; the connector is inserted into a connecting channel of a female connector and two limiting buckles of a limiting member hold the connector tightly.

[0021] After adopting the above solution, the working principle of a pipe quick-connect structure of the utility model is as follows:

[0022] The male connector and the female connector of the pipe quick-connect assembly are used to connect different pipe fittings; when different pipe fittings are connected, the connector head of the male connector is inserted into the connecting channel of the female connector. During the insertion process, the connector head first causes the two limit buckles of the limit member to move relative to each other so that the connector head can be inserted between the two limit buckles. Then the elastic arm of the limit buckle is reset so that the two limit buckles of the limit buckle are reset to hold the connector head, thereby realizing the connection of different pipe fittings; and when the connected pipe fittings are separated, the user first presses the two limit buckles of the limit member and the two limit buckles of the limit member move relative to each other, so that the two limit buckles of the limit member release the connector head inserted into the connecting channel. At this time, the user can pull the connector head out of the connecting channel to realize the separation of the pipe fittings.

[0023] The utility model has the following features:

[0024] 1. The two limiting buckles of the limiting member of the present invention are connected by an elastic arm. In this way, the relative positions of the two limiting buckles of the limiting member are determined, so that the limiting member can be directly installed in the female connector without having to consider the problem of the two limiting buckles avoiding each other, making the pipe quick-connect assembly of the present invention easy to assemble;

[0025] 2. The present invention utilizes the elastic arms of the two connected limit buckles to reset the two limit buckles. In this way, there is no need to set a retaining wall for the elastic sheet to abut against in the connecting channel of the female connector, which simplifies the structure of the female connector and reduces the transverse dimension of the female connector. As a result, the overall transverse dimension of the pipe quick-connect assembly of the present invention can be reduced, making it suitable for places with limited space.

[0026] 3. The limiting member of the present invention is installed on the female joint, and the female joint can limit the limiting member to prevent it from falling out, thereby ensuring that the quick-connect assembly of the pipe fitting and the male joint are firmly connected.

[0040] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0041] like Figures 1 to 6 As shown, the utility model discloses a pipe quick-connect structure, which includes a male connector and a pipe quick-connect assembly for connecting with the male connector, the male connector is provided with a connecting head; the pipe quick-connect assembly includes a female connector 2 and a limiter 3, the female connector 2 is provided with a connecting channel 21 for inserting the connecting head 11, and connecting through holes 22 communicating with the connecting channel 21 are respectively opened on both sides of the female connector 2, the limiter 3 is installed in the female connector 2, the limiter 3 has two limiting buckles 31 and at least one elastic arm 32 connecting the two limiting buckles 31, the two limiting buckles 31 are respectively slidably connected with the connecting through holes 22 on both sides of the female connector 2, and the two limiting buckles 31 can move relative to each other to clamp or loosen the connecting head 11 inserted into the connecting channel 21.

[0042] The working principle of a pipe quick-connect structure of the utility model is:

[0043] The male connector 1 and the female connector 2 of the pipe quick-connect assembly are used to connect different pipe fittings; when different pipe fittings are connected, the connecting head 11 of the male connector 1 is inserted into the connecting channel 21 of the female connector 2. During the insertion process, the connecting head 11 first causes the two limiting buckles 31 of the limiting member 3 to move relative to each other so that the connecting head 11 can be inserted between the two limiting buckles 31, and then the elastic arms 32 of the limiting buckles 31 are reset so that the two limiting buckles 31 of the limiting buckle 31 are reset and hold the connecting head 11 (that is, in a locked state), thereby realizing the connection of different pipe fittings; and when the connected pipe fittings are separated, the user first presses the two limiting buckles 31 of the limiting member 3 and the two limiting buckles 31 of the limiting member 3 move relative to each other, so that the two limiting buckles 31 of the limiting member 3 release the connecting head 11 inserted into the connecting channel 21 (that is, in an unlocked state). At this time, the user can pull the connecting head 11 out of the connecting channel 21 to realize the separation of the pipe fittings.

[0044] The two limit buckles 31 of the limit member 3 of the present invention are connected by the elastic arm 32, so that the relative positions of the two limit buckles 31 of the limit member 3 are determined, so that the limit member 3 can be directly installed in the female connector 2 without considering the problem that the two limit buckles 31 avoid each other, making the pipe quick-connect assembly of the present invention convenient to assemble; moreover, the present invention utilizes the elastic arms 32 of the two connected limit buckles 31 to reset the two limit buckles 31, so that there is no need to set a retaining wall for the spring clip to abut against in the connecting channel 21 of the female connector 2, making the structure of the female connector 2 simple, thereby making the lateral size of the female connector 2 smaller, making the overall lateral size of the pipe quick-connect assembly of the present invention small and suitable for places with narrow space; in addition, the limit member 3 of the present invention is installed on the female connector 2, and the female connector 2 can limit the limit member 3 and prevent the limit member 3 from falling out, thereby ensuring a firm connection with the male connector 1.

[0045] In the embodiment of the present invention, a sealing ring 4 is provided on the outer side of the connector 11 , and the sealing ring 4 is used to seal with the inner wall of the connecting channel 21 to prevent water leakage.

[0046] In the embodiment of the present invention, the outer wall of the connector 11 is provided with a connecting ring groove 111; and the limiting buckle 31 is provided with an arm 311 that cooperates with the connecting ring groove 111, and the inner side of the arm 311 has an arc-shaped limiting bayonet 3111 and an avoidance bayonet 3112, and the radius of the avoidance bayonet 3112 is larger than the radius of the limiting bayonet 3111; wherein, when the elastic arm 32 of the limiting member 3 is extended, when the limiting bayonet 31 of the two limiting buckles 31 of the limiting member 3 is 111 is opposite to and snaps into the connecting ring groove 111 of the connecting head 11, ensuring that the limit member 3 stably limits the connecting joint; when the two limit buckles 31 of the limit member 3 are pressed to make the elastic arm 32 of the limit member 3 be compressed to the point where the avoidance slots 3112 of the two limit buckles 31 of the limit member 3 are opposite to each other, the connecting head 11 can freely pass through the avoidance channel formed by the avoidance slots 3112 of the two limit buckles 31 of the limit member 3, so that the connecting head 11 can be pulled out of the connecting channel 21.

[0047] In an embodiment of the present utility model, an insertion bevel 3113 is provided on the same side of the arms 311 of the two limiting buckles 31 of the limiting member 3. When the connector 11 of the male connector 1 is inserted into the connecting channel 21 of the female connector 2, the end of the connector 11 will push against the insertion bevel 3113 of the two limiting buckles 31 of the limiting member 3, so that the two limiting buckles 31 of the limiting member 3 can move relative to each other more smoothly, thereby allowing the connector 11 to be smoothly inserted between the two limiting buckles 31.

[0048] In an embodiment of the present utility model, a positioning block 3114 is provided on the outer side of the arm 311 of the two limiting buckles 31 of the limiting member 3; the two limiting buckles 31 of the limiting member 3 are also provided with a positioning slot 312 for inserting the positioning block 3114; when the two limiting buckles 31 of the limiting member 3 are pressed so that the positioning blocks 3114 of the two limiting buckles 31 are respectively inserted into the positioning slots 312 of the two limiting buckles 31, the avoidance slots 3112 of the two limiting buckles 31 of the limiting member 3 are relative to each other, thereby ensuring the accuracy of pressing.

[0049] In an embodiment of the present invention, the position-limiting member 3 has two elastic arms 32, which allow the two position-limiting buckles 31 of the position-limiting member 3 to be reset more smoothly. The two ends of one of the two elastic arms 32 are connected to the same side of the two position-limiting buckles 31, and the two ends of the other of the two elastic arms 32 are connected to the other side of the two position-limiting buckles 31. The elastic arms 32 are arranged at an angle, which makes the elastic arms 32 more flexible and helps to reduce the lateral size of the position-limiting member 3.

[0050] In an embodiment of the present invention, the elastic clips and elastic arms 32 of the limiter 3 are integrally arranged, so that the limiter 3 itself does not need to be assembled, thereby making the assembly of the pipe quick-connect structure of the present invention more convenient; the elastic clips and elastic arms 32 of the limiter 3 can be integrally injection molded.

[0051] In an embodiment of the present invention, a mounting protrusion 313 is provided on the outer side of at least one of the two limiting buckles 31 of the limiting member 3; a mounting hole 23 connected to the mounting protrusion 313 is provided on the side wall of the female connector 2, thereby mounting the limiting member 3 in the female connector 2. Preferably, the outer sides of both limiting buckles 31 of the limiting member 3 are provided with a mounting protrusion 313, so that the limiting member 3 fits more stably in the female connector 2; the mounting protrusion 313 and the mounting hole 23 can be slidably engaged, so that when the two limiting buckles 31 of the limiting member 3 are pressed, the mounting hole 23 can guide the two limiting buckles 31 and prevent the two limiting buckles 31 from deflecting; and the mounting protrusion 313 has inclined surfaces 3131 formed on both sides to facilitate the mounting protrusion 313 to be directly engaged in the mounting hole 23. When assembling the limiting member 3 with the female connector 2, the limiting member 3 is directly inserted into the female connector 2 from a connecting through hole 22 of the female connector 2, so that the mounting protrusion 313 of the limiting member 3 is directly inserted into the mounting hole 23 of the female connector 2, which is convenient for assembly.

[0052] 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.
