[0036] Furthermore, a bushing 523 is fitted onto the rotating shaft 52.

[0037] The working principle of this utility model is as follows:

[0038] Before installing the door body 1, the pivot assembly of this application is first assembled on the top of the door body 1. During installation, the operator moves the door body 1 and the pivot assembly as a whole onto the door frame 2 to be assembled. Then, the rotating shaft 1-1 at the bottom of the door body 1 is rotated and engaged with the bottom of the door frame 2. At this time, the pivot assembly at the top of the door body 1 is exposed and visible. Then, the relative position of the fixing seat 3 on the door frame 2 is adjusted vertically. During assembly, the upper end of the pivot assembly needs to be able to rotate and engage with the movable cavity of the fixing seat 3. After determining the height of the fixing seat 3, the fixing seat 3 is locked in the designated position on the door frame 2 using the locking part 4. Then, the door body 1 is aligned and assembled. In this application, although the operator still needs to move the door body 1 and the pivot assembly as a whole onto the door frame 2, the operator only needs to move the relative position of the fixed seat 3 on the door frame 2 during the alignment and installation process of the pivot assembly and the fixed seat 3. The fixed seat 3 has a simple and lightweight structure, is easy to operate, and reduces the difficulty of installation alignment. In addition, since the fixed seat 3 can be adjusted arbitrarily on the door frame 2 by the locking part 4, it can be used for the installation of door bodies 1 of different heights, and its application range is wider.

[0039] In the above technical solution, as an embodiment 1, the pivot assembly can be selected as a fixed plate 51 fixed on the door body 1, and a pivot 52 set on the fixed plate 51, with a linkage block 521 set on the pivot 52. The movable cavity can be set by opening a channel 31 at the lower end of the fixed seat 3 and opening a groove 32 at the upper end of the fixed seat 3. A positioning ring 33 is assembled on the groove 32, and an arc-shaped part 6 is set on the positioning ring 33. That is to say, the channel 31, the groove 32 and the positioning ring 33 together form a movable cavity. When the pivot assembly is assembled, the upper end of the pivot 52 is located in the movable cavity, and the outer periphery of the pivot 52 is in movable cooperation with the arc-shaped part 6 of the positioning ring 33. When the door is opened or closed, the pivot 52 will rotate along the arc-shaped part 6, and the linkage block 521 on the pivot 52 will rotate against the inner wall of the movable cavity.

[0040] Regarding the positioning ring 33 in the above-mentioned technology, a protrusion 331 can be provided on the positioning ring 33, and multiple positioning grooves 321 can be provided in the groove 32. When the protrusion 331 is embedded in any positioning groove 321, the positioning ring 33 is positioned and installed in the groove 32. In this application, the multiple positioning grooves 321 are set in a corrugated structure, which is not only aesthetically pleasing, but also allows the relative position of the positioning ring 33 in the groove 32 to be adjusted according to the needs of the application scenario.

[0041] In the above technical solution, in order to prevent noise from being generated when the fixed seat 3 and the door body 1 are in contact during the rotation of the door body 1, this application provides a limiting platform 522 at the lower end of the rotating shaft 52. After the rotating shaft 52 is installed, the limiting platform 522 will abut against the lower end of the fixed seat 3, so that there is a gap between the fixed seat 3 and the door body 1, thereby reducing the generation of noise.

[0042] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
