Description

Technical Field

[0001] The utility model relates to the field of drains, in particular to a ceramic top cover of a drain. Background Art

[0002] The drain is used to be installed on the drain outlet of the washbasin to control water storage and drainage. The ceramic drain top cover is made of the same material as the ceramic basin body, which can improve the fit with the basin body and make the overall look more beautiful and generous. It is deeply loved by consumers. However, if the ceramic cover body is threadedly connected to the bounce core, the threads on the ceramic cover body are easily scratched during use, affecting the use effect. Therefore, a drain disclosed in application No. 202020804447.5 is connected by glue, which overcomes the defect that the threads on the ceramic cover body are easily scratched. However, multiple glue injections are required during installation, and processing is more inconvenient. Utility Model Content

[0005] Furthermore, the support wing is arranged on the upper part of the card, its upper end is connected to the card, and its lower end is far away from the card, and the distance from the outer side of the lower end of the support wing to the center of the card is greater than the radius of the installation groove.

[0006] Furthermore, the vertical distance from the lower end of the supporting wing to the top of the clamp is smaller than the height of the fixing cavity.

[0007] Furthermore, a water stop ring groove is provided on the side of the connecting piece.

[0008] Furthermore, the diameter of the connecting piece is larger than the diameter of the mounting groove.

[0009] Furthermore, the bottom of the ceramic cover and the top of the connecting piece are flat.

[0010] Furthermore, the distance from the fixing cavity to the bottom of the ceramic cover body is greater than the distance from the lower end of the supporting wing to the bottom of the clamp.

[0011] The beneficial effect of the utility model is that: the clamp is placed in the installation groove, and the elastic supporting wing shrinks along the installation groove until the lower end of the supporting wing enters the wider fixing cavity and automatically unfolds to restore the original shape, and the connecting piece is tightened. Under the restriction of the limit groove, the clamp moves toward the connecting piece, and the supporting wing abuts against the lower wall of the fixing groove. The connecting piece moves upward and abuts against the bottom of the ceramic cover body, so that the connecting piece and the expanded supporting wing clamp the cover body together to complete the installation of the connecting piece. No glue is required during the installation process, and the overall installation is convenient. In addition, the ceramic top cover does not need to be provided with threads, and the reliability after installation is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described below in conjunction with the accompanying drawings:

[0017] A ceramic top cover of a drain comprises a ceramic cover body 1, a clamp 2 and a connecting piece 3, wherein the bottom of the ceramic cover body 1 is concavely provided with a mounting groove 4, the edge of the mounting groove 4 is provided with three limiting grooves 6, the upper part of the mounting groove 4 extends outward to form a fixing cavity 5, the bottom of the clamp 2 is provided with a clamp internal thread 21, the side of the clamp 2 is provided with a limiting rail 23 matching the limiting groove 6, and three supporting wings 22 with elastic deformation ability are respectively provided between adjacent limiting rails 23, and the supporting wings 22 can be made of plastic material, the limiting rail 23 is aligned with the limiting groove 6, the clamp 2 is placed in the mounting groove 4 along the limiting groove 6, and the supporting wings 22 are squeezed inward by the side wall of the mounting groove 4 until the supporting wings 22 are placed in the wider fixing cavity 5 and re-engaged. Stretch out to restore the original shape. At this time, the support wing 22 is stuck in the fixed cavity 5 and cannot be pulled out. The top of the connecting piece 3 is provided with a connecting piece external thread 33 which is threadedly connected with the clamping piece internal thread 21. By twisting the connecting piece 3 inward, the clamping piece 2 moves toward the connecting piece 3 under the restriction of the limit groove 6, so that the support wing 22 is against the lower wall of the fixed cavity 5. At the same time, the connecting piece 3 also moves toward the clamping piece 2 to press against the bottom of the ceramic cover body 1, so that the support wing 22 and the connecting piece 3 are tightly clamped to the ceramic cover body 1 at the same time, so that the connecting piece 3 is stably installed on the ceramic cover body 1, the operation is simple, and the stability of the connecting piece after installation is high.
