DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0028] Figures 1 to 3 A quick-insert structure of an expansion water tank interface is shown, comprising an interface seat 1 arranged on an expansion water tank body 100 and a quick-insert connector 2 plugged and connected to the interface seat 1; the interface seat 1 comprises a fixing portion 11 and an interface end portion 13, one end of the quick-insert connector 2 is connected to the interface end portion 13, and the other end is connected to a connecting pipe 21;

[0029] A clamping portion 12 is provided between the fixing portion 11 and the interface end portion 13, and a limiting rib plate 14 is provided on the fixing portion 11;

[0030] The quick-connect connector 2 includes a connector body 24 and a pipe end connector 22, wherein the connector body 24 includes a clamping terminal 241 and a sealing tube portion 242;

[0031] At least one clamping strip 26 is provided in the connector body 24 and is engaged with the clamping portion 12. The clamping strip 26 is used to engage with the clamping portion 12. The limiting rib 14 is used to strengthen the structural strength of the fixing portion 11 and to limit the connector body 24 so that the fitting depth of the connector body 24 is adapted to the clamping point, thereby avoiding over-installation or under-installation and enhancing the reliability of the connection.

[0032] The sealing tube portion 242 is fitted with the interface end 13, and a sealing ring 25 is provided inside the sealing tube portion 242 to cooperate with the joint end to complete the sealing. The pipe end joint 22 is threadedly connected to the sealing tube portion 242, and the end of the pipe end joint 22 close to the outside is connected to the connecting pipe 21.

[0033] Specifically, the clamping strip 26 is streamlined, and specifically includes a fixed end and a movable end. A clamping bend portion for engaging with the corresponding clamping portion 12 is provided between the fixed end and the movable end. The fixed end is fixed to the inner side of the connector body 24. The movable end is provided with a slide column 28. The connector body 24 is provided with a slide groove 27. The slide column 28 is engaged in the slide groove 27 and passes through the slide groove 27 for disassembling the quick-connect connector 2. When the slide column 28 is toggled, the movable end of the clamping strip 26 drives the clamping bend portion to begin to deform, thereby disengaging the clamping connection, and then the quick-connect connector 2 can be pulled out.

[0034] In order to make the clamping more stable, the clamping bend is provided with a clamping block 261 adapted to the clamping portion 12, and the clamping block 261 can be in an oblique pointed shape, such as Figure 3 As shown, such a shape is to prevent the clamping bend from limiting the clamping portion 12 when the clamping strip 26 undergoes slight deformation, thereby improving the stability of the clamping.

[0035] A limit slider 29 is provided at the end of the slide post 28 passing through the slide slot 27 to prevent the clamping strip 26 from deforming and causing the slide post 28 to escape from the slide slot 27 when the slide post 28 is moved, and to prevent the clamping strip 26 from deforming in an unsuitable manner, thereby ensuring that the quick-connect connector 2 can be disassembled smoothly.

[0036] The clamping portion 12 is in the shape of a cone with a larger end close to the fixing portion 11 and a smaller end close to the interface end 13, so that when the clamping function is played, the resistance to the clamping operation is reduced, making the clamping process smoother; specifically: the diameter of the end of the clamping portion 12 close to the fixing portion 11 is larger than the outer diameter of the fixing portion 11, and the diameter of the end close to the interface end 13 is equal to the outer diameter of the interface end 13.

[0037] A limit block 23 is provided at one end of the outer side of the pipe end joint 22 to prevent the threaded connection from being too deep and to enhance the self-locking of the threaded connection.

[0038] The detachable connection between the pipe end joint 22 and the joint body 24 is for the convenience of replacing the connecting pipe 21. The pipe end joint 22 and the connecting pipe 21 are an integrally formed structure with better integrity and sealing, higher strength, reduced risk of leakage, and longer service life.

[0039] The method and process of using the interface quick-insert structure of the expansion water tank mainly include:

[0040] Alignment and insertion: Align the sealing tube portion 242 of the quick-connect connector 2 with the interface seat 1 on the expansion water tank to ensure that the direction of the clamping end 241 is correct; then, smoothly insert the quick-connect connector 2 into the interface seat 1, and push the quick-connect connector 2 until the limiting rib plate 14 contacts the connector body 24 to limit further insertion depth and ensure that the clamping point is in the correct position; at the same time, after the clamping is completed, the sealing tube portion 242 is completely fitted with the sealing ring 25 of the interface end 13 to form an effective seal.

[0041] Disassembly operation: Move the slide post 28 to make the movable end of the clamping strip 26 drive the clamping bent portion to deform and disengage from the clamping state with the clamping portion 12, and then gently pull out the quick-connect connector 2 to complete the disassembly.

[0042] In summary, the expansion water tank interface quick-insert structure provided by the utility model effectively solves the problems existing in the prior art and significantly improves the installation efficiency, connection reliability, maintenance convenience and overall aesthetics of the expansion water tank interface.
