Description
Technical Field
[0001] This utility model relates to the field of rotating structure technology, and in particular to an upper rotating mechanism for a pivot door. Background Technology
[0002] A hinged door is a door whose leaves rotate around a vertical axis to open and close. It is one of the important forms of access control. When installing a hinged door, the upper rotating component is usually embedded in a hole in the wall or in the upper door frame. The existing rotating mechanism is difficult to adjust after installation, and the alignment accuracy requirements for subsequent door leaf installation are high, which increases the installation difficulty and adjustment complexity of this type of hinged door. Utility Model Content
[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing an upper rotating mechanism for a pivot door.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The present invention discloses an upper rotating mechanism for a pivot door, comprising a bottom shell, a sliding seat slidably connected to the bottom shell, and a pivot body rotatably connected to the sliding seat; an eccentric component is rotatably connected to the bottom shell; rotating the eccentric component allows the sliding seat to slide along the bottom shell.
[0005] Furthermore, a connecting plate is fixed to the top surface of the bottom shell; a through-shaft strip hole is provided on the surface of the connecting plate for the rotating shaft body; a second circular hole is provided on the connecting plate; a first circular hole is provided on the inner bottom wall of the bottom shell; a strip-shaped recess is provided on the surface of the sliding seat; and an adjustment strip hole is provided on the bottom surface of the strip-shaped recess. The length direction of the adjusting strip hole is perpendicular to the length direction of the strip concave hole; the eccentric component consists of a limiting round shaft and an upper rotating shaft and a lower rotating shaft respectively disposed on the upper and lower end faces of the limiting round shaft; the upper rotating shaft and the lower rotating shaft are both disposed at the eccentric position of the limiting round shaft; The diameter of the limiting circular shaft is equal to the width of the strip-shaped concave hole; the limiting circular shaft is embedded in the strip-shaped concave hole; the upper rotating shaft and the lower rotating shaft are rotatably connected to the second circular hole and the first circular hole, respectively.
[0006] Furthermore, a sliding block is provided on the side wall of the sliding seat; a guide groove is provided on the side wall of the bottom shell; and the sliding block is embedded in the guide groove.
[0007] Furthermore, the surface of the sliding seat is evenly distributed with multiple teeth; the bottom surface of the connecting plate is provided with tooth grooves that match the teeth; the teeth and tooth grooves are arranged along the sliding direction of the sliding seat; the connecting plate is provided with bolt slot holes; the sliding seat is provided with clamping thread holes; after the clamping bolt passes through the bolt slot holes, it is threaded into the clamping thread holes to engage the teeth in the tooth grooves.
[0008] Furthermore, the rotating shaft body includes a fixed sleeve and a rotating shaft; the sliding seat is provided with a bushing mounting hole; a bushing is provided in the bushing mounting hole; the rotating shaft is inserted into and rotatably connected to the bushing; the shaft body of the rotating shaft is provided with an external thread; the inner side wall of the sleeve is provided with an internal thread hole that matches the external thread; the external thread is threadedly connected to the internal thread hole.
[0009] Furthermore, the bottom of the bottom shell is provided with a bottom through hole at the position directly opposite the rotating shaft; the bottom of the rotating shaft is provided with a bottom handle hole.
[0010] Furthermore, the side wall of the rotating shaft is provided with multiple safety pin holes.
[0011] Furthermore, a handle hole is provided on the upper rotating shaft.
[0012] The beneficial effects of this utility model after adopting the above structure are as follows: 1. The base shell, fixing sleeve, and rotating shaft are designed as separate units. The fixing sleeve and rotating shaft are fixed to the wall or door frame, while the base shell is fixed to the door leaf. When opening and closing the door, the door leaf, base shell, and sliding seat rotate together around the rotating shaft body. Rotating the eccentric component pushes the sliding seat to slide inside the base shell, realizing the relative sliding between the rotating shaft body and the base shell. This allows for adjustment of the gap between the door leaf and the wall, improving the convenience of door leaf installation and the sealing performance after installation.
[0013] 2. Multiple safety pin holes are provided on the side wall of the pivot. The safety pin holes are located at different length positions of the pivot. By inserting one of the pins into the safety pin hole, the end of the pin extends outside the safety pin hole. The pin limits the movement, thereby preventing the pivot from passing through the connecting plate during long-term rotation of the door leaf and causing the door leaf to fall, thus increasing safety.
