Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0023] In one embodiment, such as Figure 1-4 As shown, a hinge for preventing the hinge cup from disengaging includes a hinge cup 1 and a mounting base 2, and further includes:

[0024] A connecting shaft 12 is provided. The hinge cup 1 and the mounting base 2 are respectively installed on the cabinet body and the cabinet door, allowing the cabinet door to rotate. A hinge arm 3 is provided on the outside of the mounting base 2. A rotating shaft 9 is provided on the outside of the hinge arm 3. A connecting block 4 is provided on the outer wall of the mounting base 2. The rotating shaft 9 is rotatably disposed between two connecting blocks 4. A return spring 10 is sleeved on the outside of the rotating shaft 9, which can drive the hinge arm 3 to return to its original position. A bushing 13 is provided on the outside of the hinge cup 1. A connecting shaft 12 is provided on the outside of the hinge arm 3. One end of the connecting shaft 12 passes into the inside of the bushing 13. The hinge arm 3 is rotatably disposed inside the hinge cup 1 through the cooperation of the bushing 13 and the connecting shaft 12. The connecting shaft 12 is connected to the hinge cup 1 through the bushing 13, which reduces the wear of the connecting shaft 12 during use, prevents the connecting shaft 12 from separating from the hinge cup 1, and improves the service life of the hinge.

[0025] Rotating sleeve 21, a support frame 14 is fixedly installed on the hinge arm 3, a positioning plate 20 is installed inside the support frame 14, and a guide rod 19 is installed on the positioning plate 20. One end of the guide rod 19 slides into the inside of the support frame 14. The guide rod 19 is connected to the support frame 14 through a return spring. The return spring guides the rod 19 evenly through its elastic force. In the initial position, the two guide rods 19 approach each other and drive the connecting shaft 12 to move into the support frame 14, so that the connecting shaft 12 is disengaged from the bushing 13, which facilitates the disassembly and maintenance of the hinge. Rotating sleeve 21 is rotatably installed on the positioning plate 20. One end of the connecting shaft 12 passes into the inside of the support frame 14 and is connected to the rotating sleeve 21. The rotating sleeve 21 is provided with a locking bolt 24 for fixing the connecting shaft 12. By unscrewing the locking bolt 24, the connecting shaft 12 can be separated from the rotating sleeve 21, which facilitates the replacement of the damaged connecting shaft 12.

[0026] A fixing mechanism is provided inside the support frame 14, which can fix the positioning plate 20 and the rotating sleeve 21.

[0027] The hinge that prevents the hinge cup from disengaging consists of a hinge cup 1, a mounting base 2, and a hinge arm 3. The hinge arm 3 is located between the hinge cup 1 and the mounting base 2. The connecting shaft 12 is connected to the hinge cup 1 through a bushing 13, which reduces the wear of the connecting shaft 12 during use and prevents the connecting shaft 12 from disengaging from the hinge cup 1. The connection and disassembly of the hinge cup arm 3 and the hinge cup 1 are relatively convenient, which facilitates the subsequent disassembly and maintenance of the hinge. As an embodiment, the left, right, up, and down positions of the various components shown in the attached figure are only one arrangement method. The specific positions are set according to specific needs.

[0028] In one embodiment, such as Figure 1-4 As shown, the fixing mechanism includes a support rod 17, a rotating block 15, and a cam 22. The support rod 17 is rotatably mounted inside the support frame 14, and the cam 22 is fixedly mounted outside the support rod 17. The positioning plate 20 is provided with a pressure block 23 that contacts the cam 22. The top end of the support rod 17 extends out of the support frame 14 and is provided with the rotating block 15. The rotating block 15 is provided with multiple fixing screws 16. The support rod 17 drives the cam 22 to rotate, and the cam 22 presses the positioning plate 20 to both sides. The positioning plate 20 drives the connecting shaft 12 to pass through the inside of the support frame 14, so that the connecting shaft 12 passes into the inside of the bushing 13, realizing the docking of the hinge arm 3 and the hinge cup 1.

[0029] In one embodiment, such as Figure 1-4 As shown, a tension spring 18 is provided inside the support frame 14. One end of the tension spring 18 is connected to the cam 22. The tension spring 18 pulls the cam 22, causing the cam 22 to be positioned... Figure 3 The initial position is shown.

[0030] In one embodiment, such as Figure 1 As shown, the mounting base 2 is provided with mounting screws 8, and a washer 7 is provided between the mounting screws 8 and the mounting base 2.

[0031] In one embodiment, such as Figure 1 As shown, the mounting base 2 is provided with a connecting part 5 on the outside, the connecting part 5 is provided with a through hole 6, and the hinge cup 1 is provided with a mounting hole 11.

[0032] The above embodiments of this utility model provide a hinge to prevent the hinge cup from disengaging. The hinge cup 1 and the mounting base 2 are respectively installed on the cabinet door and the cabinet body. The hinge cup arm 3 is rotated so that one end of the hinge cup arm 3 passes into the interior of the hinge cup 1. The rotating block 15 drives the support rod 17 to rotate. The support rod 17 drives the cam 22 inside the support frame 14 to rotate. The cam 22 presses the positioning plate 20 to both sides. The positioning plate 20 drives the connecting shaft 12 to pass out from the interior of the support frame 14. The connecting shaft 12 passes into the interior of the bushing 13. The rotating block 15 is fixed by the fixing screw 16, so that the hinge arm 3 and the hinge cup 1 can be connected. When it is necessary to disassemble the hinge, the fixing screw 16 is removed, the support rod 17 is rotated, and the connecting shaft 12 passes into the interior of the support frame 14, making the disassembly of the hinge cup arm 3 and the hinge cup 1 more convenient and quick.

[0033] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
