[0039] In one possible implementation, the groove 14 adopts an L-shaped structure, and the base claw 32 slides into the vertical section of the groove 14 until the buckle 31 is engaged in its corresponding slot 12. At this time, the base claw 32 reaches the connection between the vertical section and the horizontal section of the groove 14.

[0040] In one possible implementation, rotating the base 3 causes the base claw 32 to slide within the horizontal section of the groove 14 until the arrows on the quick-connect connector housing 1 and the base 3 are aligned, at which point the connector is in a locked state.

[0041] In one possible implementation, an annular groove is provided in the middle section of the outer side wall of the quick connector housing 1, and several guide grooves are evenly provided in the inner wall of the annular groove, which penetrate into the interior of the quick connector housing 1.

[0043] In one possible implementation, the outer wall of the base 3 is provided with anti-slip texture, and the anti-slip texture is arranged in a grid pattern. The rear end of the base 3 is provided with an integral limiting groove, and the cross-section of the limiting groove is rectangular. On the left and right sides of the inner wall of the limiting groove, there is an integral limiting block, and the limiting blocks are distributed in an L-shape.

[0044] In one possible implementation, an arrow mark is provided at the rear end of the outer side wall of the quick-connect connector housing 1, and an arrow mark is also provided at the rear end of the outer side wall of the base 3. The arrow mark on the quick-connect connector housing 1 and the arrow mark on the base 3 are initially at a 90° angle. In a further preferred embodiment, the locking block has a T-shaped cross section, and the front end of the locking block extends into the guide groove and is movably connected thereto. A return spring integral with the locking block is fixedly connected to the rear end of the locking block, and the other end of the return spring is fixed to the inner wall of the base 3. In its natural state, the return spring pushes the locking block to always move toward the guide groove.

[0045] In one possible implementation, the inner wall of the guide groove is provided with a plurality of locking teeth integrally therewith, and the locking teeth are equidistantly arranged along the arc trajectory of the guide groove. The outer wall of the locking block is fixed with a locking protrusion integral therewith, and the locking protrusion is engaged with the locking teeth.

[0046] In one possible implementation, the inner wall of the front end of the quick-connect connector housing 1 is provided with a guide slope, and the guide slope matches the outer wall of the front end of the male connector 4. The guide slope gradually tapers backward from the front end of the quick-connect connector housing 1.

[0047] In one possible implementation, the inner wall of the annular groove in the middle section of the outer side wall of the quick-connect connector housing 1 is evenly provided with several guide grooves that extend into the interior of the quick-connect connector housing 1. Several locking blocks integrally connected to the inner wall of the base 3 are fixedly connected, and the locking blocks are movably connected to the guide grooves. The base 3 is rotatably connected to the quick-connect connector housing 1 through the locking blocks. The rear end of the inner wall of the quick-connect connector housing 1 is provided with a positioning boss 13. The outer side wall of the front end of the male connector 4 is provided with a male connector 4 groove that matches the positioning boss 13. The rear end of the male connector 4 groove is provided with an elastic retaining ring. The inner wall of the rear end of the quick-connect connector housing 1 is provided with a sealing cavity, and a sealing ring is embedded in the inner wall of the sealing cavity. The outer side wall of the base 3 is provided with anti-slip texture. The rear end of the base 3 is provided with a limiting groove, and a limiting block is provided on each of the left and right sides of the inner wall of the limiting groove. The rear end of the outer side wall of the quick-connect connector housing 1 is provided with an arrow mark, and the rear end of the outer side wall of the base 3 is also provided with an arrow mark. The locking block has a T-shaped cross-section. The front end of the locking block extends into the guide groove and is movably connected to it. The rear end of the locking block is fixedly connected with a return spring. The other end of the spring is fixed to the inner wall of the base 3. Several locking teeth are integrally formed on the inner wall of the guide groove. The locking protrusion is fixed on the outer wall of the locking block. The inner wall of the front end of the quick connector housing 1 is provided with a guide slope. When the male connector 4 is inserted into the quick connector housing 1, the front end of the male connector 4 enters the interior of the quick connector housing 1 along the guide slope. The positioning boss 13 and the groove of the male connector 4 cooperate to ensure the correct installation direction of the male connector 4. During the continued insertion of the male connector 4, the sealing ring is squeezed to deform it and form a seal. After the elastic retaining ring passes over the positioning boss 13, it rebounds and locks the positioning boss 13 to prevent the male connector 4 from falling out. At this time, the base 3 is rotated counterclockwise. The base 3 drives the locking block to move along the guide groove. The locking protrusion on the locking block meshes with the locking teeth on the inner wall of the guide groove to generate resistance. When the arrow mark on the quick connector housing 1 coincides with the arrow mark on the base 3, the locking protrusion is completely locked into the last locking tooth to complete the locking. The limiting groove and the limiting block limit the rotation angle of the base 3 to prevent excessive rotation. The anti-slip texture increases the friction and facilitates operation.

[0048] By employing the above-mentioned technical means:

[0049] 1. By setting an annular groove on the outer wall of the quick-connect connector housing and opening a guide groove on its inner wall, and setting a locking block on the inner wall of the base, the rotational connection between the base and the quick-connect connector housing is realized by the cooperation of the locking block and the guide groove. This simplifies the complex assembly structure of the traditional quick-connect connector, reduces the number of parts, and lowers the production cost.

[0050] 2. By setting locking teeth on the inner wall of the guide groove and locking protrusions on the outer wall of the locking block, the resistance is generated by the meshing connection between the two. The locking status can be clearly felt during the rotation of the base, ensuring that the male connector can be firmly locked after insertion. Installation and disassembly can be completed without additional tools, improving the convenience of operation in narrow spaces.

[0051] 3. By setting a guide slope on the inner wall of the front end of the quick connector housing, the male connector can be quickly and accurately inserted into the quick connector housing. At the same time, an elastic retaining ring is set at the rear end of the male connector groove. After the elastic retaining ring passes over the positioning boss, it rebounds and locks the positioning boss, effectively preventing the male connector from accidentally coming out and improving the connection reliability.

[0052] Working principle, refer to Figure 1-8 When assembling the quick-connect connector, first insert the sealing ring 2 into the sealing cavity 11 of the housing, then align the buckle 31 of the base 3 with the slot 12 of the quick-connect connector housing 1 and press it in until the buckle 31 is fully pressed into the slot 12. Figure 6 As shown, the base assembly is now complete, and the base claw 32 is also snapped into the housing groove 14.

[0053] When the male connector 4 is inserted into the quick-connect connector housing 1, the positioning boss 13 on the housing and the male connector groove 41 cooperate to ensure the correct installation direction of the male connector 4. After the male connector 4 is fully inserted, rotate the base 3 counterclockwise so that the arrows on the quick-connect connector housing 1 and the base 3 are aligned. At this time, the connector is in the locked state. Figure 8 As shown.

[0054] Based on the above technical solution, it can also have the following technical features: when using the connector in a narrow space, it can be directly adjusted to the locking state for installation. At this time, the male connector can be directly inserted and will not come out, thus improving the convenience of installation.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
