The connecting body 1 is a rotating component when the door of the mobile refrigerator is opened and closed, the hinge seat 2 is fixed on the box body of the mobile refrigerator, and the connecting body 1 is rotationally connected with the hinge seat 2. Because it leads to the door to damage because of great external force impact easily when removing the refrigerator door and opening, consequently connector 1 need break away from hinge seat 2 when removing the refrigerator door and receiving great power, avoid hinge fracture or damage, this embodiment sets up magnetism block structure 11 and a plurality of first bolt hole 12 on connector 1, and be used for the open slot 13 of being connected with hinge seat 2, magnetism block structure 11 is connected with hinge seat 2, first bolt hole 12 is used for being fixed in connector 1 on the door closure of removing the refrigerator, open slot 13 is used for holding the rotating part of hinge seat 2. The magnetic engaging structure 11 includes a rotor 14, and a pair of first and

second magnets

15 and 16 with opposite poles, wherein the rotor 14 is provided with a rotation fulcrum 141, a second magnet fixing groove 142 and a turning shaft fulcrum 143, and the rotation fulcrum 141 is cylindrical and is clamped in the corresponding fixing groove of the connecting body 1 as a fulcrum when the rotor 14 rotates. The second magnet fixing groove 142 is used for fixing the second magnet 16, and the turning shaft supporting point 143 is used for abutting against the connecting part of the hinge base 2, so that the connecting body 1 and the hinge base 2 are connected into a whole. The connection body 1 is further provided with a first magnet fixing groove 17 for fixing the first magnet 15. The first magnet fixing groove 17 corresponds to the second magnet fixing groove 142, so that the first magnet 15 and the second magnet 16 with different poles attract each other, and in a normal use state, the turnover shaft fulcrum 143 abuts against the connecting part of the hinge base 2, so that the connecting body 1 can rotate around the hinge base 2, and the refrigerator door can be normally opened and closed by moving; when the connecting body 1 receives a large impact force when moving the refrigerator door, the turning shaft fulcrum 143 moves downwards, the hinge base 2 is separated from the open slot 13, and then the rotating piece 14 returns to the original position due to the attraction of the magnet. By arranging the magnetic clamping structure 11, the connecting body 1 and the hinge base 2 are in rotating connection in a normal state, and the refrigerator door is normally opened and closed; when the mobile refrigerator door is subjected to large impact force, the connecting body 1 is separated from the hinge seat 2, the hinge is prevented from being broken or damaged, the connecting body 1 is easily mounted on the hinge seat 2 again after separation, normal use is recovered, the rotating part 14 is made of a metal material, the precision is high, the rotating part is smooth and small in abrasion, the connecting body can be used for multiple times, and the service life is long.
