[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] Existing pipe joints are connected by thread or snap connection, which has the problems of inconvenience in installation and disassembly and high difficulty in operation.

[0033] In order to solve the above technical problems, this embodiment provides a quick-install and quick-release connector. Figures 1 to 5 As shown, Figure 1 It is a stereoscopic diagram of the quick-install and quick-release connector in the embodiment. Figure 2 This is an exploded view of the quick-install and quick-release connector in the embodiment. Figure 3 It is a cross-sectional view of the quick-install and quick-release connector in the embodiment. Figure 4 It is a schematic diagram of the locking process of the quick-install and quick-release connector in the embodiment, Figure 5 Schematic diagram of the unlocking process of the quick-install and quick-release connector in the embodiment.

[0034] The quick-install and quick-release connector of this embodiment includes a connector assembly 1 and a plug assembly 2 .

[0035] The connector assembly 1 includes a quick connector 11, a push block 12 and an elastic member 13. The quick connector 11 is provided with a socket 101 and a guide hole 102 connected to the socket 101. The push block 12 is disposed in the guide hole 102 and can move along the extension direction of the guide hole 102. The elastic member 13 is located in the guide hole 102 and between the push block 12 and the quick connector 11.

[0036] The plug assembly 2 includes a connector 21 for inserting into the socket 101, and a slider 22 sleeved on the outside of the connector 21. The connector 21 includes a limiting portion 201 and a head 202 arranged in sequence in the insertion direction. The slider 22 is limited between the head 202 and the limiting portion 201 and can slide between the head 202 and the limiting portion 201. The external dimensions of the slider 22 are larger than the external dimensions of the head 202.

[0037] See also Figure 4 and Figure 5 As shown, the assembly and disassembly process of the quick-install and quick-disconnect connector of the above technical solution is as follows: in the initial state, that is, when the connector 21 is separated from the quick-connect connector 11, the push block 12 extends into the socket 101 under the elastic force of the elastic member 13, as shown in FIG. Figure 4 ① state shown; before the connector 21 is inserted into the quick connector 11 to the locking position, the head 202 pushes the push block 12 through the inclined surface to compress the elastic member 13 and moves into the guide hole 102, and the slider 22 is blocked by the push block 12 and moves toward the limit portion 201, such as Figure 4 When the connector 21 and the quick connector 11 are in the locked position, the push block 12 moves to the side of the head 202 in the removal direction under the push of the compressed elastic member 13, and blocks the head 202 from moving in the removal direction, thereby achieving locking in the removal direction. Since the head 202 releases the push on the push block 12 at this time, a sense of gear position can be generated that can be perceived by the user, so that the user knows that the locking operation is completed. Figure 4 When unlocking, the connector 21 is moved in the insertion direction from the locked position to the unlocked position. During this process, the slider 22 is supported by the limit portion 201 and pushes the push block 12 to move into the guide hole 102 through the inclined surface, as shown in FIG. Figure 5 As shown in state ⑤, until the connector 21 is in the unlocked position, at this time, the push block 12 is located on the side of the slider 22 in the pull-out direction, and the push block 12 no longer blocks the slider 22, as shown in FIG. Figure 5 When the connector 21 moves in the unlocked position in the direction of extraction, the slider 22 moves in the direction of the limit portion 201 with the head 202 as support, and the push block 12 moves into the guide hole 102 through the inclined surface, such as Figure 5 As shown in state ⑦, until the connector 21 and the slider 22 are out of contact with the push block 12, the connector 21 can be pulled out from the quick connector 11 to achieve disassembly, as shown in FIG. Figure 5 It can be seen that the quick-install and quick-disconnect connector of the above technical solution can be locked and installed by inserting the plug component 2 into the connector component 1, and the plug component 2 can be disassembled by pushing it in the insertion direction for a distance and then pulling it out when locked, which saves time and effort for users to operate, and has the advantages of high disassembly and assembly efficiency and simple and convenient operation.

[0038] In one embodiment of the connector 21, see Figure 2 and Figure 3As shown, the connector 21 includes a quick-connect plug 211 and a mounting joint 212 connected by threads, the limiting portion 201 is located at the end where the mounting joint 212 is connected to the quick-connect plug 211, the head 202 is located at the end of the quick-connect plug 211 away from the mounting joint 212, and the slider 22 is movably sleeved on the outside of the quick-connect plug 211; with such a configuration, during installation, the slider 22 can be first inserted into the quick-connect plug 211, and then the quick-connect plug 211 and the mounting joint 212 can be threadedly connected, which facilitates the installation of the slider 22.

[0039] Exemplarily, a threaded hole is provided at one end of the mounting connector 212, and a stud connected to the threaded hole is provided at one end of the quick-connect plug 211.

[0040] Exemplarily, an annular step structure for connecting to an external pipeline is provided on the outer side of the mounting joint 212 .

[0041] In one embodiment of the head 202 pushing the push block 12 through the inclined surface, see Figure 2 and Figure 3 As shown, a first inclined surface 203 is provided at one end of the head 202 facing the insertion direction, and the first inclined surface 203 is inclined from the outside of the head 202 to the inside; a second inclined surface 103 is provided at one end of the push block 12 away from the elastic member 13, and the second inclined surface 103 is inclined from the outside of the push block 12 to the inside in the direction in which the push block 12 enters the insertion hole 101; before the connector 21 is inserted into the quick-connect connector 11 to the locking position, the head 202 pushes the second inclined surface 103 of the push block 12 through the first inclined surface 203 to move the push block 12 into the guide hole 102; before the connector 21 moves from the locking position to the unlocking position in the insertion direction, the slider 22 pushes the second inclined surface 103 to move the push block 12 into the guide hole 102; it can be seen that through the interaction between the first inclined surface 203 and the second inclined surface 103, the automatic movement of the push block 12 during the insertion process of the connector 21 is realized, and at the same time, the insertion process of the plug is smoother and the resistance during insertion is reduced.

[0042] Exemplarily, only the first inclined surface 203 is provided on the head 202 or only the second inclined surface 103 is provided on the push block 12 , so that the head 202 can push the push block 12 through the inclined surface.

[0043] In one embodiment of the above-mentioned sliding block 22 pushing the push block 12 through the inclined surface, see Figure 2 and Figure 3As shown, a third inclined surface 204 is provided at one end of the slider 22 away from the head 202, and the third inclined surface 204 is inclined from the outside to the inside in the direction of the connector 21 being pulled out; when the connector 21 moves in the direction of the pull-out at the unlocked position, the push block 12 blocks the third inclined surface 204 of the slider 22, so that the slider 22 moves toward the limit portion 201 until it contacts the limit portion 201, at which time the push block 12 is separated from the head 202 and the obstruction to the head 202 is released. With such a configuration, the movement of the slider 22 under the obstruction of the push block 12 is achieved through the interaction between the third inclined surface 204 of the slider 22 and the push block 12, thereby achieving the unlocking of the plug, and at the same time making the unlocking process simpler and more convenient, thereby improving the convenience of operation.

[0044] In one embodiment of the push block 12 being disposed in the guide hole 102, see Figure 2 and Figure 3 As shown, a retaining wall 104 is provided on the inner side of the guide hole 102 near the insertion hole 101, and a convex portion 105 is provided on the outer side of the push block 12; when the connector 21 is separated from the quick connector 11, the push block 12 is pushed into the insertion hole 101 by the compressed elastic member 13 until the convex portion 105 contacts the retaining wall 104. That is to say, when the connector 21 is separated from the quick connector 11, the push block 12 can be pushed into the insertion hole 101 by the elastic member 13 until the convex portion 105 contacts the retaining wall 104, thereby ensuring the stable position of the push block 12 when not inserted, realizing the stable positioning of the push block 12 in the insertion hole 101, and improving the stability and reliability of the push block 12.

[0045] Further, in order to facilitate the installation of the elastic member 13 and the push block 12, for example, refer to Figure 2 and Figure 3 As shown, the guide hole 102 connects the socket 101 and the outside of the quick connector 11. The quick connector 11 includes a fixed cover 14. The fixed cover 14 is arranged on the end of the guide hole 102 away from the socket 101. The elastic member 13 is located between the push block 12 and the fixed cover 14. The elastic member 13 is supported by the fixed cover 14 when compressed. During installation, the push block 12 and the elastic member 13 are placed in the guide hole 102 in turn, and then the guide hole 102 is sealed by the fixed cover 14; wherein the fixed cover 14 can be connected to the inner wall of the guide hole 102 by means of threads, snaps and other structures.

[0046] Exemplarily, the guide hole 102 is a blind hole, and the elastic member 13 and the push block 12 are installed from the insertion hole 101 into the guide hole 102 .

[0047] For example, see Figure 2 and Figure 3As shown, the guide holes 102 are perpendicular to the socket 101 and are arranged at equal intervals in the circumferential direction with the socket 101 as the center. A group of push blocks 12 and elastic members 13 are respectively provided in each guide hole 102. For example, two groups of sockets 101, push blocks 12 and elastic members 13 are arranged opposite to each other or three groups of sockets 101, push blocks 12 and elastic members 13 are arranged at an interval of 120 degrees. Each push block 12 locks the connector 21 at the same time, thereby improving the stability and reliability of the quick-install and quick-release connector in the locked state.

[0048] Exemplarily, the elastic member 13 is a linear spring or a compression spring.

[0049] Exemplarily, the slider 22 is a ring-shaped structure.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
