Description

Technical Field

[0001] The present invention relates to the technical field of connectors, in particular to quick connectors. Background Art

[0002] The quick connector is also called a drain quick connector. The drain quick connector is used to connect the steel head and the connecting pipe at the bottom of the washbasin. After searching the patent document with the announcement number CN2 connector 644675U, a quickly detachable drain is provided, including an upper wall body, a lower wall body, a nut, a sealing gasket, and a pin. The upper outer wall of the upper wall body is covered with a nut, and the nut cooperates with the thread of the outer wall of the upper wall body. The lower part of the upper wall body is inserted into the upper part of the lower wall body, and the outer wall of the lower part of the upper wall body contacts the upper inner wall of the lower wall body. The lower outer wall of the upper wall body is provided with a semicircular groove, and a concave groove is provided at the same position on the upper outer circular inner wall of the lower wall body, and an opening is opened on the outer wall of the lower wall body. The concave groove and the semicircular groove form a through hole, and the upper wall body and the lower wall body are connected at the through hole by a pin. However, it was found during its use that the overall volume of the above-mentioned device is large and cannot be installed in a narrow space, resulting in poor use effect of the device. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a quick connector that effectively reduces the overall size, is easy to install in a small space, and saves space.

[0004] The quick connector of the present invention includes a main body and a connecting piece, the interior of the main body is provided with symmetrical raised guide rails, the connecting piece is installed in the main body, the bottom end of the connecting piece is symmetrically provided with pendant pieces, the back of the pendant pieces is slidably clamped with the raised guide rail of the main body, and also includes a connecting component, the connecting component is installed on the connecting piece, the connecting component is used to quickly connect the steel head of the external basin, and the middle part of the main body is provided with a thread, the external sewer pipe is screwed to the main body, and the bottom of the main body extends into the external sewer pipe; the connecting piece is installed in the main body, and the steel head of the external basin is clamped through the connecting component, and the external sewer pipe is screwed to the main body, and the bottom of the main body extends into the external sewer pipe. At this time, the main body and the external sewer pipe form a semicircular water outlet, thereby effectively reducing the overall size, making its overall size smaller, and convenient for installation in a narrow space, saving space.

[0005] Preferably, the connecting assembly includes two groups of threaded arc plates and multiple groups of compression springs, and the two groups of threaded arc plates are symmetrically installed at the bottom end of the connecting piece, and the two groups of threaded arc plates and the hanging pieces at the bottom end of the connecting piece just form a circular ring, and the edge of the bottom end of the upper part of the threaded arc plate is installed with a compression spring, and the bottom end of the compression spring is in contact with the main body; the external steel head is inserted into the main body, and at this time, with the cooperation of the compression spring, the threaded arc plate moves downward, and the diameter of the threaded arc plate becomes larger. At this time, the main body is rotated, and the threaded arc plate rebounds, thereby realizing the clamping of the steel head. In this process, only two rotations of the main body are required to realize the quick clamping connection of the steel head, which saves time and effort and improves the convenience of use of the device.

[0006] Preferably, a groove is provided at the top of the connecting piece, and there are two overflow outlets in the groove; when the basin overflows, the overflowing water reaches the overflow outlet through the groove, and then flows into the main body and out through the external sewer pipe, effectively solving the overflow problem and improving the use effect of the device.

[0007] Preferably, a water-sealing frame is provided at the bottom of the main body, and a rubber pad is provided at the lower end of the water-sealing frame; when water is discharged from the main body, the water pushes the rubber pad box downward, thereby draining the water. When the main body drains water, the rubber pad is pushed back by the air pressure in the pipeline. At this time, the rubber pad plays the role of sealing water and preventing odor.

[0008] Preferably, a sealing gasket is provided at the connection between the connecting piece and the steel head of the wash basin; by providing the sealing gasket, water leakage at the connection between the connecting piece and the steel head of the wash basin is avoided, thereby improving the sealing performance of the device.

[0009] Preferably, the main body is provided with anti-skid grooves; by providing the anti-skid grooves, slipping is avoided when the main body is rotated, and bumps and damages are avoided, thereby improving the reliability of the device.

[0010] Compared with the prior art, the beneficial effects of the present invention are: the connecting part is installed in the main body, and the steel head of the external basin is clamped through the connecting assembly, and the external drain pipe is screwed to the main body, and the bottom of the main body extends into the external drain pipe. At this time, the main body and the external drain pipe form a semicircular water outlet, thereby effectively reducing the overall size, making its overall size smaller, easy to install in a narrow space, and saving space.
