Description

Technical Field

[0001] The utility model relates to the technical field of glass door hinges, in particular to a rotating structure of a buffer hinge. Background Art

[0002] A glass door hinge is a connecting piece for installing a glass door. Generally, a glass door hinge consists of a fixed leaf, a movable leaf and a rotating shaft. The leaves are respectively connected to the frame and the glass door, and then connected through the rotating shaft to movably connect the frame and the glass door. In order to counteract the elastic force of the spring when the hinge is closed, a damper needs to be added inside the hinge to form a buffering effect when closing the door, overcoming the noise interference caused by quickly closing the door.

[0003] The applicant publicly disclosed a single-opening hydraulic buffer glass door hinge with the application number 202222130841.7 on December 27, 2022. Its moving seat is rotatably hinged to the limit shaft mounting seat through a limit shaft. A limit cam is provided in the middle section of the limit shaft. A damper is provided in the moving seat corresponding to the limit cam. The extending end of the damper contacts the first hinge seat. A rib is provided at the end of the cylinder body of the damper corresponding to the limit cam. First springs and second springs for providing a return acting force for the limit shaft are respectively provided on both sides of the damper. Although it solves the buffering problem of the glass hinge closing too fast, this structure can only be applied to some glass doors with a small weight. When used on a glass door with a large weight, due to the insufficient bearing capacity of the limit bearing, the situation of the door body offset occurs. Therefore, it is necessary to make further optimization. Summary of the Utility Model

[0021] As Figures 1 to 5 shown, a rotating structure of a buffer hinge includes a first hinge seat 10, a second hinge seat 20, a pivot member 30 and a first fixing screw 40;

[0022] Specifically, a receiving groove 101 is provided on the inner side surface of the first hinge seat 10. The pivot member 30 includes a connecting portion 31 for connecting with the first hinge seat 10 and a rotating portion 32 for rotatably connecting with the second hinge seat 20. The connecting portion 31 is adapted to the receiving groove 101. Mounting blocks 311 are symmetrically arranged on the upper and lower sides of the connecting portion 31. Through holes 312 are transversely formed in the mounting blocks 311. A threaded hole 102 is provided in the left side of the receiving groove 101 corresponding to the through hole 312. The threaded portion of the first fixing screw 40 passes through the through hole 312 and is connected to the threaded hole 102, so that the connecting portion 31 is fixed in the receiving groove 101. Specifically, to fix the connecting portion 31 of the pivot member 30 in the first hinge seat 10, the first fixing screw 40 for fastening needs to be horizontally arranged on the upper and lower sides of the connecting portion 31, and then the threaded portion of the first fixing screw 40 passes through the through hole 312 of the mounting block 311 and is connected to the threaded hole 102 of the first hinge seat 10. After tightening the first fixing screws 40 on the upper and lower sides of the connecting portion 31 respectively, the connection between the pivot member 30 and the first hinge seat 10 is completed. The first fixing screw 40 is not visible on the outer surface of the first hinge seat 10, making the hinge more aesthetically pleasing as a whole.

[0023] Specifically, a chamfer is provided between the bottom surface and the upper and lower side surfaces of the receiving groove 101 to form a first chamfer 103. Second chamfers 313 are provided on the upper and lower sides of the connecting portion 31. The first chamfer 103 is adapted to the second chamfer 313. When the pivot member 30 is correspondingly placed in the receiving groove 101, the second chamfer 313 at the rear side of the pivot member 30 is correspondingly fitted to the first chamfer 103 between the bottom and side surfaces of the receiving groove 101, ensuring that the pivot member 30 will not swing up and down after the screws are tightened.

[0024] Specifically, positioning posts 104 are arranged along the depth direction on the upper edge of the receiving groove 101. Positioning holes 314 are provided on the pivot member 30 corresponding to the positioning posts 104. The positioning posts 104 are adapted to the positioning holes 314, so that the positioning posts 104 are inserted into the positioning holes 314. Specifically, a second fixing screw 50 is provided in the positioning hole 314. The second fixing screw 50 passes through the positioning hole 314 and is screwed to the positioning post 104. It should be understood that the positioning hole 314 is partially a counterbore structure. The positioning posts 104 and the positioning holes 314 ensure the accuracy of the installation position of the pivot member 30. By tightening the second fixing screw 50, the connection stability of the relative front and rear positions between the pivot member 30 and the first hinge seat 10 is ensured.

[0025] Specifically, a buffer mechanism is provided inside the second hinge seat 20. The buffer mechanism at least includes an elastic member and a damper. The rotating part 32 at least includes a first cam part and a second cam part. The first cam part abuts against the elastic member, and the second cam part abuts against the damper, so that the elastic member and the damper act on the rotating part 32. The elastic member and the damper are common buffer structures of a buffer hinge. The elastic member provides compression energy storage for the rotating part 32 in the door-opening state and releases potential energy when closing the door, and provides damping buffering through the damper to make the hinge close slowly.
