[0004] The above-mentioned equipment does not use bolts or other fixed connection structures during use, meaning the entire device is movable. This avoids the problem of bolts being too tight and unable to be opened, allowing the device to be opened quickly, thereby achieving the purpose of quickly disassembling the cabinet door.

[0005] In actual use, if the second pivot and the limiting block become loose, the cabinet door may fall off, resulting in poor structural stability. Furthermore, the connecting parts are mostly located on the outside of the cabinet body and the cabinet door, which is aesthetically unappealing and does not meet the aesthetic standards of modern people when choosing kitchen cabinets. Therefore, it is necessary to propose a cabinet door connecting device.

[0006] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

The cabinet body 1 has symmetrically opened through holes 3. A rotating shaft 4 is installed between two through holes 3. One end of the rotating shaft 4 is fixedly connected to an internal hexagonal fixing head 5. The other end of the rotating shaft 4 is provided with a threaded part 6. The cabinet door 2 has an open movable groove 7 that is used to cooperate with the rotating shaft 4. The external thread of the threaded part 6 is connected to an external hexagonal nut 8. The internal thread of the external hexagonal nut 8 is provided with a threaded groove 9 that is used to cooperate with the threaded part 6. The inner bottom of the cabinet body 1 has a hexagonal limiting groove 10 that is used to cooperate with the external hexagonal nut 8. The inner top of the cabinet body 1 has a circular groove 11 that is used to cooperate with the internal hexagonal fixing head 5. The cabinet body 1 has symmetrically opened mounting grooves 12. Each mounting groove 12 is installed with a bearing 13 inside.

[0029] In this embodiment, two bearings 13 are respectively placed in the mounting slots 12 on the upper and lower sides of the cabinet 1. The bearings 13 can improve the smoothness of the rotation of the shaft 4 and reduce wear. The cabinet door 2 is placed inside the cabinet 1, and the two ends of the movable slot 7 are aligned with the upper and lower through holes 3 inside the cabinet 1 on the same vertical horizontal line. The external hexagonal nut 8 is placed inside the hexagonal limiting slot 10 and tightened. The internal hexagonal fixing head 5 drives the shaft 4 to pass through the bearing 13 and through hole 3 at the top, and the threaded part 6 passes through the cabinet. The movable groove 7 inside the door 2 passes through the bearing 13 and through hole 3 at the bottom of the cabinet 1, and the threaded part 6 is threadedly connected to the external hexagonal nut 8. By inserting a hexagonal wrench into the internal hexagonal fixing head 5, the rotating shaft 4 is fixed to the external hexagonal nut 8, thus completing the installation of the cabinet door 2. The structure is simple and reasonable, with strong stability; it does not damage the exterior of the cabinet 1 and the cabinet door 2, and is aesthetically pleasing; it solves the problem that the traditional cabinet 1 and cabinet door 2 need to be fixed with hinges and bolts, which are easy to loosen or difficult to disassemble.

[0030] Example 2

[0031] like Figures 1-5 As shown, the cabinet door 2 has an inclined part 14 on its exterior. The outer surface of the inclined part 14 is symmetrically fixedly connected with a first magnet 15. The inner wall of the cabinet body 1 is symmetrically fixedly connected with a fixing frame 16 that works with the first magnet 15. Each fixing frame 16 has a second magnet 17 installed inside it. The first magnet 15 and the second magnet 17 have opposite magnetic poles. The cabinet body 1 has a T-shaped handle 18 installed on its exterior.

[0032] In this embodiment, the cabinet door 2 is rotated by the T-shaped handle 18. When the cabinet door 2 rotates, the first magnet 15 on the outside of the inclined part 14 is driven into the interior of the fixed frame 16 and attracted by the second magnet 17, thereby improving the tightness of the cabinet door 2. The structure is simple, the cost of use is low, and it is easy to promote and use.

[0033] The working principle of this embodiment is as follows: When in use, the installation steps are as follows: First, place the two bearings 13 into the mounting slots 12 on the upper and lower sides of the cabinet 1 respectively. The bearings 13 can improve the smoothness of the rotation of the shaft 4 and reduce wear.

[0034] Second: Place cabinet door 2 inside cabinet body 1, and make the two ends of movable groove 7 and the two upper and lower through holes 3 inside cabinet body 1 on the same vertical horizontal line.

[0035] Third: Insert the external hexagonal nut 8 into the hexagonal limiting groove 10 and tighten it; drive the rotating shaft 4 through the internal hexagonal fixing head 5 to pass through the bearing 13 and through hole 3 at the top, and the threaded part 6 passes through the movable groove 7 inside the cabinet door 2 and exits through the bearing 13 and through hole 3 at the bottom of the cabinet body 1, so that the threaded part 6 is threadedly connected to the external hexagonal nut 8. Insert a hexagonal wrench into the internal hexagonal fixing head 5 to fix the rotating shaft 4 and the external hexagonal nut 8, and the installation of the cabinet door 2 can be completed. The structure is simple and reasonable, and the stability is strong; there is no damage to the exterior of the cabinet body 1 and the cabinet door 2, and the aesthetics are strong; it solves the problem that the traditional cabinet body 1 and cabinet door 2 need to be fixed with hinges and bolts, which are easy to loosen or difficult to disassemble and assemble.

[0036] Fourth: The cabinet door 2 is rotated by the T-shaped handle 18. When the cabinet door 2 rotates, the first magnet 15 on the outside of the inclined part 14 is driven into the interior of the fixed frame 16 and is attracted to the second magnet 17, thereby improving the tightness of the cabinet door 2. The structure is simple, the cost of use is low, and it is easy to promote and use.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
