DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1:

[0024] Reference Figure 1-5 The hidden side-mounted large-angle opening and closing hinge comprises: a mounting seat 1 and a support seat 2 connected to the mounting seat 1; a support arm 3 detachably connected to the support seat 2, specifically, a rotating shaft 201 is connected to the support seat 2, and the rotating shaft 201 is plugged into the support arm 3, wherein a fixed seat 7 is fixedly connected to the support arm 3; a hinge head 4 rotatably connected to the support arm 3, specifically, a wear-resistant sleeve is provided on the rotating shaft of the support arm 3, and the hinge head 15 is sleeved on the wear-resistant sleeve; wherein a buffer seat 5 is slidably connected to the support arm 3, One end of the buffer seat 5 is detachably connected with a connecting spring 502, and the other end of the connecting spring 502 is fixedly connected to the fixed seat 7, and the support arm 3 is fixedly connected with a buffer damper 501, and the buffer damper 501 matches the buffer seat 5; a connecting ear 506 is fixedly connected to the hinge head 4; a buffer arm 504, and the connecting ear 506 is connected with a second rotating shaft 505, and the buffer seat 5 is connected with a first rotating shaft 503, and both ends of the buffer arm 504 are rotatably connected to the first rotating shaft 503 and the second rotating shaft 505 respectively.

[0025] The hinge head 4 is detachably connected with a second magnet 401, and the support arm 3 is detachably connected with a first magnet 301, and the first magnet 301 and the second magnet 401 are magnetically attracted to each other;

[0026] The fixing seat 7 is provided with an L-shaped guide groove 701, a pull rod 702 is slidably connected in the guide groove 701, a connecting spring 502 is fixedly connected to the pull rod 702, and a circular arc groove 703 is provided on the buffer seat 5, and the circular arc groove 703 matches the pull rod 702;

[0027] When using the device, when the hinge head 4 is closed, the buffer arm 504 is driven to move, so that the buffer arm 504 pushes the buffer seat 5 to move backward. When the hinge head 4 is closed to a certain angle, the arc groove 703 of the buffer seat 5 contacts the pull rod 702 and pushes the pull rod 702 to move up along the L-shaped guide groove 701. At this time, the pull rod 702 can slide in the guide groove 701, that is, the connecting spring 502 is not locked, so that the connecting spring 502 pulls the pull rod 702, the buffer seat 5, the buffer arm 504, and the hinge head 4 to slide, and slowly closes with the cooperation of the buffer damper 501;

[0028] At the same time, the first magnet 301 and the second magnet 401 are arranged in cooperation, and after the hinge head 4 rotates a certain angle, the magnetic attraction force for restoring the hinge seat 4 is provided to realize the closing of the hinge head 4;

[0029] When opening the hinge head, the hinge head 4 is rotated to open, and the pull rod 702 slides along the guide groove 701 for a certain distance and then gets stuck in the short part of the L shape. At this time, the buffer seat 5 is separated from the pull rod 702, and the hinge head 4 can be opened and closed freely at a large angle.

[0030] Embodiment 2:
