Description

Technical Field

[0001] This utility model relates to the field of cabinet door hinge technology, and in particular to an automatic reset hinge. Background Technology

[0002] Automatic door hinges, which can automatically close cabinet doors, are widely used in freezers, refrigerators, blast freezers, and disinfection cabinets. Different manufacturers have different production standards, resulting in varying mounting hole positions on the cabinet doors for fixing the hinges. Because the mounting hole positions of existing automatic door hinges are fixed, in order to accommodate different cabinet door sizes, it is necessary to produce automatic door hinges with multiple different mounting hole positions, leading to higher manufacturing costs. Utility Model Content

[0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides an automatic reset hinge.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an automatic reset hinge, including a hinge body, a mounting platform at the top of the hinge body, a mounting groove at the top of the mounting platform, a fixing piece movably mounted in the mounting groove, a pressure cap detachably mounted on the top of the mounting platform, and a positioning hole for mounting countersunk screws at the end of the fixing piece away from the hinge body.

[0005] Furthermore, the inner wall of the mounting groove is provided with limiting teeth, and the side wall of the fixing plate near the hinge body is provided with teeth that match the limiting teeth. The hinge shaft is rotatably installed in the mounting groove, and the fixing plate is provided with an oblong hole that matches the hinge shaft. The oblong hole is parallel to the mounting groove.

[0006] Furthermore, a through hole is provided in the middle of the pressure cap, the diameter of which is larger than the diameter of the hinge shaft. Countersunk grooves are provided on the top surface of the pressure cap near the four ends, and locking bolts are fitted into the countersunk grooves. Threaded holes matching the locking bolts are provided on the top surface of the mounting platform.

[0007] Furthermore, the positioning hole includes a first mounting hole and a second mounting hole. The first mounting hole has an elongated oval structure, and the second mounting hole has a circular structure. The top of the sidewalls of both the first mounting hole and the second mounting hole are provided with a tapered surface.

[0008] The beneficial effects of this utility model are that, through the design of a mounting platform at the top of the hinge body, the fixing plate is movably installed in the mounting groove at the top of the mounting platform and fixed by the cooperation of the limiting teeth and the teeth. When the hinge body is installed on the cabinet door, by adjusting the position of the fixing plate in the mounting groove, the second mounting hole is aligned with the adjacent mounting hole, and the position of the countersunk screw in the first mounting hole is adjusted. Therefore, it can be applied to cabinet doors with different mounting hole positions within a certain range, thereby improving the versatility of the automatic door hinge and helping to reduce the manufacturing cost of the automatic door hinge.

[0015] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0016] according to Figure 1-4As shown, an automatic reset hinge includes a hinge body 1. The hinge body 1 has a mounting platform 11 at its top. The mounting platform 11 has a mounting groove 12 at its top, and a fixing piece 2 is movably mounted within the mounting groove 12. A pressure cap 3 is detachably mounted on the top of the mounting platform 11. The fixing piece 2 has a positioning hole for installing countersunk screws at its end away from the hinge body 1. The positioning hole includes a first mounting hole 23 and a second mounting hole 24. The first mounting hole 23 is oblong, and the second mounting hole 24 is circular. The top of the sidewalls of both the first and second mounting holes 23 and 24 are provided with tapered surfaces 25. During fixing, countersunk screws are installed in the first mounting hole 23 and the second mounting hole 24, respectively. The size of the second mounting hole 24 matches the size of the countersunk screw. By adjusting the position of the countersunk screw in the first mounting hole 23, it can be adapted to mounting holes with different centers. After the countersunk screw is tightened, the head of the countersunk screw is in close contact with the tapered surface 25, thereby improving the stability of the fixing piece 2 on the cabinet door.

[0017] In this embodiment, the inner wall of the mounting groove 12 is provided with limiting teeth 13, and the side wall of the fixing piece 2 near the hinge body 1 is provided with teeth 21 that match the limiting teeth 13. The hinge shaft 4 is rotatably installed in the mounting groove 12. The fixing piece 2 is provided with an oblong hole 22 that matches the hinge shaft 4. The oblong hole 22 is parallel to the mounting groove 12. The fixing piece 2 is installed in the mounting groove 12. The limiting teeth 13 and teeth 21 are engaged with each other to limit the fixing piece 2. The hinge shaft 4 passes through the oblong hole 22 and is avoided by the oblong hole 22.

[0018] In this embodiment, a through hole 31 is provided in the middle of the pressure cover 3. The diameter of the through hole 31 is larger than the diameter of the hinge shaft 4. Countersunk grooves 32 are provided on the top surface of the pressure cover 3 near the four ends. Locking bolts 5 are installed in the countersunk grooves 32. Threaded holes 14 matching the locking bolts 5 are provided on the top surface of the mounting platform 11. The pressure cover 3 is fixedly installed on the top of the mounting platform 11 by the locking bolts 5. The hinge shaft 4 passes through the through hole 31 and protrudes outward to facilitate connection with the sheet metal parts on the cabinet.

[0019] In use, the position of the fixing piece 2 in the mounting groove 12 is adjusted according to the mounting hole position of the cabinet door, so that the second mounting hole 24 is aligned with the mounting hole position near the hinge body 1. Then, the pressure cover 3 is installed on the mounting platform 11 and fixed with the locking bolt. The pressure cover 3 prevents the fixing piece 2 from detaching from the hinge body 1. Then, the countersunk screws are installed into the first mounting hole 23 and the second mounting hole 24 respectively, and the position of the countersunk screws in the first mounting hole 23 is adjusted. Therefore, it can be applied to cabinet doors with different mounting hole positions within a certain range, thereby improving the versatility of the automatic door hinge and helping to reduce the manufacturing cost of the automatic door hinge.
