Description

Technical Field

[0001] This utility model relates to the field of safe technology, specifically a safe door hinge structure. Background Technology

[0002] Currently, hinges are widely used in the industry as the connecting component between cabinet doors and cabinet bodies. Hinges enable the cabinet door to rotate and open around the cabinet body. This connection method is widely used in various cabinet products due to its mature structure. When installing hinges, holes need to be drilled on the side of the cabinet door and at the corresponding connection position on the cabinet body. After drilling the holes, multiple screws are used to pass through the mounting holes of the hinges in sequence and screw them into the pre-drilled holes on the cabinet door and cabinet body. The engagement of the screw threads achieves a fixed connection between the hinge and the cabinet door, and between the hinge and the cabinet body, thus completing the assembly of the cabinet door and cabinet body. The cabinet door connection method based on metal hinges described above is cumbersome to disassemble and assemble in actual application. Since the connection between the metal hinges and the cabinet door and cabinet body depends on the fixing of multiple screws, when the cabinet door is installed for the first time, the operator must complete the alignment and screwing of multiple screws one by one, and must ensure that the tightening torque of each screw is consistent to avoid uneven force on the hinge and deformation of the cabinet door. When the cabinet door needs to be disassembled for maintenance, multiple screws must be unscrewed one by one to separate the hinges from the cabinet door and cabinet body. The entire disassembly and assembly process is cumbersome.

[0003] Therefore, it is necessary to propose a cabinet door hinge structure to solve the above problems. Utility Model Content

One end of the door hinge passes through the shaft connecting plate, and the other end of the door hinge is fixedly connected to an end plate. A spring piece is provided at the end of the bearing seat away from the shaft connecting plate. The spring piece is fixedly connected to the door plate to limit the axial movement of the door hinge.

[0006] Preferably, one end of the spring is fixedly connected to the door panel, and the other end of the spring extends upward at an angle.

[0007] Preferably, the distance between the spring sheet and the bearing seat is greater than the thickness of the end plate.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figure 1-3 As shown, a cabinet door hinge structure includes a door panel 1 and a door frame 2. Both ends of one side of the door panel 1 are fixedly connected to a pivot seat 6. The two pivot seats 6 are provided with a pivot plate 8 fixedly connected to the door frame 2 on the side away from each other. A door pivot 7 passes through the pivot seat 6. One end of the door pivot 7 passes through the pivot plate 8. The other end of the door pivot 7 is fixedly connected to an end plate 5. A spring piece 4 is provided at the end of the pivot seat 6 away from the pivot plate 8. The spring piece 4 is fixedly connected to the door panel 1 to limit the axial movement of the door pivot 7.

[0016] When installing door panel 1, place it in door frame 2 and align the two pivot seats 6 with the two pivot connecting plates 8 respectively. Pass one end of the door hinge 7 through the pivot seats 6 and pivot connecting plates 8 in sequence, allowing door panel 1 to be rotatably connected to door frame 2 via the door hinge 7. When the door hinge 7 is inserted, it acts on the spring piece 4, causing it to elastically deform and move closer to door panel 1. After insertion, the spring piece 4 returns to its original position and abuts against one end of the door hinge 7, axially limiting it with the cooperation of the end plate 5. By setting two pivot connecting plates 8 to limit and support the two pivot seats 6, the door panel 1 is prevented from moving axially along the door hinge 7 within door frame 2. Simultaneously, with the cooperation of the spring piece 4, the connection between door panel 1 and door frame 2 is made easier.

[0017] To facilitate the installation of the door hinge 7, one end of the spring piece 4 is fixedly connected to the door panel 1, while the other end of the spring piece 4 extends upward at an angle. When the door hinge 7 is inserted into the hinge seat 6, the spring piece 4 does not interfere with the insertion. As the door hinge 7 is continuously inserted, the end plate 5 acts on the inclined surface to push the spring piece 4, causing elastic deformation. When the end plate 5 passes the spring piece 4, the spring piece 4 returns to its original position and rests against the end plate 5, thus making the installation of the door hinge 7 more convenient. Specifically, the distance between the spring piece 4 and the hinge seat 6 is greater than the thickness of the end plate 5, thereby providing sufficient space for the elastic deformation of the spring piece 4.

[0018] The end of the bearing seat 6 near the bearing plate 8 protrudes from the edge of the door panel 1. The bearing seat 6 is supported and limited by the door frame 2 to control the gap between the door panel 1 and the door frame 2, and to prevent the upper and lower sides of the door panel 1 from rubbing against the door frame 2.

[0019] Specifically, the distance between the two bearing seats 6 at their opposite ends is matched with the distance between the two shaft connecting plates 8. The bearing seats 6 are limited by the two shaft connecting plates 8, thereby preventing the door panel 1 from moving axially along the door hinge 7 and improving the stability of the door panel 1 after assembly with the door frame 2.

[0020] In some embodiments, the bearing seat 6 has a plurality of blind holes 9 staggered on both sides along its length direction. The ends of the plurality of blind holes 9 located inside the bearing seat 6 are interconnected to form through holes through which the door shaft 7 passes. This allows for the injection and retention of lubricating medium, effectively reducing rotational noise and reducing the amount of material used in processing.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
