Technical Field

[0001] This utility model belongs to the field of industrial washing machine technology, and in particular relates to a quick connector. Background Technology

[0002] Industrial washing machines are specifically designed for large-scale washing of bedding and other fabrics such as hotel sheets, duvet covers, towels, bathrobes, and curtains. They are typically more powerful and efficient than household washing machines, capable of handling large volumes of laundry, and have a longer lifespan.

[0003] Quick connectors are used when transferring liquid materials in industrial washing machines. Quick connectors are generally divided into male and female connectors. After insertion, they are fixed by a U-shaped clip. However, there is no limit to the U-shaped clip. The paper guide U-shaped clip may come out and affect the use effect. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quick connector, including a female connector and a male connector, and further comprising:

[0005] U-shaped clips are used to secure the female and male connectors after they are inserted.

[0006] The socket is formed through the female head;

[0007] A slot, which is located at the male connector's insertion end;

[0008] A buckle, which is fixedly installed on the outside of the male end, is a U-shaped elastic buckle;

[0009] When the male and female connectors are plugged in, the plug end of the male connector is located inside the female connector. After the U-shaped card is inserted into the socket, it enters the slot of the male connector to fix the position between the male and female connectors. After the U-shaped card is inserted into the slot, one end of the U-shaped card enters the slot of the buckle.

[0010] Furthermore, the U-shaped card includes:

[0011] The U-shaped part is a U-shaped rod;

[0012] Support legs, both ends of the U-shaped part are rotatably connected to support legs;

[0013] In this configuration, after the male and female connectors are inserted into the support legs, the U-shaped part rotates and engages with the buckle.

[0014] Furthermore, it also includes:

[0015] A rotating ring, which is fitted around the outside of the male end;

[0016] The slot is a ring groove, and the male and female heads are rotatably connected by a U-shaped clip that engages with the ring groove. The buckle is fixedly mounted on the rotating ring.

[0017] Furthermore, it also includes:

[0018] The slot is located on the outside of the male connector;

[0019] The rotating ring is located in the slot and is rotatably connected to the male end.

[0020] Furthermore, the rotating ring is a C-shaped elastic retaining ring, and the rotating ring is detachably connected to the male connector.

[0021] Furthermore, the notch of the buckle has rounded corners.

[0022] Furthermore, there are two buckles on the outer side of the male head. After the support leg is inserted into the male head and the female head, the two rod-shaped parts of the U-shaped part near the support leg are respectively engaged and connected with the two buckles.

[0023] The beneficial effects of this utility model are as follows:

[0024] 1. After the U-shaped card is inserted, the other end of the U-shaped card will lock into the slot of the buckle, thereby fixing the position of the U-shaped card and preventing it from coming out due to external force, thus enhancing the stability of the quick connector during use.

[0025] 2. By dividing the U-shaped clip into a U-shaped part and a support leg, and rotatably connecting the support leg to the U-shaped part, the U-shaped part can be folded and engaged with the clip after the support leg is inserted. This reduces the overall size of the quick connector, making it suitable for narrower environments and avoiding interference caused by an overly protruding U-shaped part.

[0026] 3. Because the slot is a ring groove, the male and female connectors can rotate relative to each other during connection. The male and female connectors can be rotated and connected through the cooperation of the U-shaped clip and the ring groove. In actual use, the material transfer hose is connected to the end of the quick connector. During operation, the hose will rotate at any time, and the quick connector can also rotate to prevent the hose from folding due to rotation. At the same time, the rotating ring is fitted on the outside of the male connector, and the buckle is fixed on the rotating ring. When the U-shaped clip rotates, it can drive the buckle to rotate without affecting the fixation of the U-shaped clip.

[0027] 4. By setting a slot, the position of the rotating ring is limited, preventing the rotating ring from moving on the male end, making the use more stable.

[0028] 5. Because the swivel ring is a C-shaped elastic retaining ring, the swivel ring and the male connector can be detachably connected, which facilitates the replacement of the swivel ring, reduces the production cost of the male connector, and improves economic efficiency.

[0029] 6. The rounded corners make it easier for the U-shaped part to smoothly transition into the slot of the buckle, resulting in a smoother engagement.

[0030] 7. Because there are two buckles, and the two buckles are respectively connected to the two rod-shaped parts near the support feet of the U-shaped part, the fixation of the U-shaped part is more stable, so that the U-shaped part will not wobble relative to the male head, thus enhancing the stability of use.
