[0002] With the continuous development of indoor furniture, the existing rotating push door, such as glass door, is fixed by using a door clamp when installed indoors, and then a rotating shaft is installed on the top and inserted into the shaft hole reserved in the door clamp. After installation, the door body rotates and opens through the rotating shaft. The existing installation method of the door clamp and the rotating shaft is to directly insert the rotating shaft into the reserved hole in the door clamp. However, the direct rotation connection between the rotating shaft and the door clamp will affect the durability of the door clamp, and the gap between the door clamp and the rotating shaft will become larger after a long time of wear and tear.

[0003] In order to reduce the wear and tear between the door clamp and the rotating shaft, the staff will insert a shaft sleeve into the reserved hole of the door clamp to reduce the friction between the rotating shaft and the door clamp. However, when the door body is opened, the door clamp moves with the door body, and the rotating shaft rotates relatively in the door clamp. After a long time of use, the shaft sleeve is easily displaced due to the influence of the rotating shaft, resulting in unstable door clamp structure. CONTENT OF THE INVENTION

[0007] By adopting the above technical scheme, the stabilizing piece improves the connection stability between the subsequent door clamp and the rotating shaft, the mounting groove is used to mount the stabilizing piece, which improves the stability of the stabilizing piece on the door clamp, the protrusions improve the friction between the stabilizing piece and the door clamp, which improves the stability of the stabilizing piece on the door clamp, and the limiting plate reduces the friction between the door clamp and the rotating shaft mounting carrier, which prolongs the service life of the door clamp.

[0008] Preferably, the top surface of the limiting plate is provided with a through hole along the inner wall of the positioning sleeve, and the connecting portion of the limiting plate and the positioning sleeve is rounded.

[0009] By adopting the technical scheme, the through hole is convenient for subsequent installation of the rotating shaft in the positioning sleeve, the connecting part of the limiting plate and the positioning sleeve is rounded, the rotating shaft is convenient for installation in the positioning sleeve, and the friction between the rotating shaft and the stabilizing piece is reduced.

[0010] Preferably, the positioning sleeve is provided with a positioning ring along the inner wall at the end away from the limiting plate.

[0011] By adopting the technical scheme, the positioning ring improves the positioning effect of the positioning sleeve on the rotating shaft.

[0012] Preferably, the convex strip is arc-shaped on one side of the door clamp.

[0013] By adopting the technical scheme, the convex strip is arc-shaped, the stabilizing piece is convenient for installation on the door clamp, the stability of the stabilizing piece on the door clamp is improved, and the adaptability of the stabilizing piece is improved.

[0014] Preferably, the corner of the end of the positioning sleeve away from the limiting plate is rounded.

[0015] By adopting the technical scheme, the corner of the end of the positioning sleeve away from the limiting plate is rounded, so that the door clamp is prevented from being scratched when the positioning sleeve is installed.
