[0002] A hinge is a mechanical device used to connect two solids and allow relative rotation between them. It is a connecting fitting between a cabinet door switch and a cabinet body. The cabinet door is like a hand, and the hinge is like a joint. A suitable hinge structure determines the installation method, opening and closing angle, service life, etc. of the cabinet door and the cabinet body.

[0003] Currently, for the door frame hinge structures on products such as cabinets, parts such as door bodies or control covers are all hinged through circular through holes and rotating shafts. For equipment such as plasma cleaners, cabinet doors are installed on the cabinet body, and the cabinet doors are relatively heavy, so the hinge structure bears more weight. The defect of the existing plasma cleaner is that the cabinet door on the plasma cleaner cabinet body is relatively heavy, and the bearing capacity of the hinge structure is insufficient. In addition, most hinge structure parts are too many and the integrity is relatively poor, so it is very easy to be damaged after long-term use. Summary of the Utility Model

[0010] A door shaft, the door shaft vertically passes through one end of the connecting pin away from the pressing block, and the door shaft can rotate relative to the connecting pin.

[0011] Further, one end of the connecting pin is a large end, and the large end has a clearance fit with the door shaft.

[0012] Further, a threaded hole is formed at one end of the connecting pin away from the large end. The threaded hole is coaxially formed along the connecting pin. The connecting pin is connected with a connecting screw through the threaded hole. The connecting screw is used to fix the pressing block and the concave seat.

[0013] The present utility model also claims protection for a plasma cleaning machine, including a cabinet body and a cabinet door. The cabinet door is rotatably installed on the cabinet body through at least one of the above hinge structures. Among them, an articulated groove is formed in the cabinet door. The large end of the connecting pin extends into the articulated groove. A rotating hole is formed in the height direction of the cabinet door. The door shaft extends into the rotating hole and passes through the large end of the connecting pin.

[0014] Further, the concave seat and the pressing block are located on the inner wall of the cabinet body, and the concave seat is fixed to the inner wall of the cabinet body.

[0015] Further, a limit screw hole is formed at the edge of the cabinet door. The cabinet door is threadedly connected with a setscrew through the limit screw hole. The end of the setscrew abuts against a limit groove formed on the door shaft.

[0016] Further, at least one counterbore is formed in the cabinet body. The concave seat is provided with a connecting screw hole corresponding to the counterbore. A fixing screw is arranged in the counterbore. The fixing screw passes through the cabinet body and is threadedly connected with the concave seat through the connecting screw hole.

[0033] This embodiment provides a hinge structure 3. By connecting the pressing block 32 through the concave seat 31 and using the connecting pin 33 to connect the concave seat 31 and the pressing block 32, the hinge structure 3 has strong integrity. The concave seat 31 and the pressing block 32 are fixed on one side of the cabinet door 2. The connecting pin 33 passes through the cabinet door 2 and is rotationally matched with the door shaft 21, improving the load-bearing capacity of the cabinet door 2. At the same time, the hinge structure 3 of the present utility model can be quickly removed from the cabinet door 2 and the cabinet body 1, and the installation is convenient.

[0034] Further, as Figure 4 shown, one end of the connecting pin 33 is a large end 331, and the large end 331 is in clearance fit with the door shaft 21. Specifically, as Figure 3 shown, the large end 331 of the connecting pin 33 is located inside the cabinet door 2, and one end of the connecting pin 33 away from the large end 331 is connected to the pressing block 32.

[0035] Further, this embodiment provides a specific structure for connecting the connecting pin 33 and the pressing block 32. A threaded hole 332 is opened at one end of the connecting pin 33 away from the large end 331. The threaded hole 332 is coaxially opened along the connecting pin 33.

After tightening and fixing the connecting screw 34 and the connecting pin 33, the pressing block 32 and the concave seat 31 are fixed, and the large end 331 of the connecting pin 33 abuts against the outside of the concave seat 31.

[0036] The present utility model also claims protection for a plasma cleaning machine, including a cabinet body 1 and a cabinet door 2. The cabinet door 2 is rotatably installed on the cabinet body 1 through at least one of the above hinge structures 3. Among them, an articulated groove 23 is opened on the cabinet door 2. The large end 331 of the connecting pin 33 extends into the articulated groove 23. A rotating hole 22 is opened in the height direction of the cabinet door 2. The door shaft 21 extends into the rotating hole 22 and passes through the large end 331 of the connecting pin 33.

[0037] According to a specific embodiment provided by the present utility model, in this embodiment, the cabinet door 2 and the cabinet body 1 adopt two hinge structures 3, which are installed at the edge along the height direction of the cabinet door 2. Specifically, during installation, the articulated groove 23 is based on the size of the large end 331 of the connecting pin 33. The large end 331 of the connecting pin 33 extends into the articulated groove 23. A rotating hole 22 is opened in the height direction of the cabinet door 2. The rotating hole 22 is opened near the edge of the cabinet door 2. The door shaft 21 extends into the rotating hole 22 and passes through the large end 331 of the connecting pin 33.

[0038] Further, the concave seat 31 and the pressing block 32 are located on the inner wall of the cabinet body 1, and the concave seat 31 is fixed to the inner wall of the cabinet body 1, which can provide higher installation strength for the hinge structure 3.

[0039] Further, a limit screw hole is formed at the edge of the cabinet door 2. A setscrew 35 is threadedly connected to the cabinet door 2 through the limit screw hole. The setscrew 35 is horizontally arranged, and the end of the setscrew 35 abuts against a limit groove 211 formed on the door shaft 21. The position of the limit groove 211 is not limited in this embodiment. Specifically, it can be formed above the connecting pin 33. When the setscrew 35 abuts against the limit groove 211, it can prevent the door shaft 21 from disengaging from the rotation hole 22 from above.

[0040] Further, at least one counterbore is formed in the cabinet body 1. The concave seat 31 is provided with a connecting screw hole corresponding to the counterbore. After the fixing screw 36 extends into the counterbore, the fixing screw 36 passes through the cabinet body 1 and is threadedly connected to the concave seat 31 through the connecting screw hole. In order to prevent the pressing block 32 and the concave seat 31 from rotating relative to the cabinet body 1, counterbores are formed in the cabinet body 1 in this embodiment. The number of counterbores can be set to two, which are respectively located on the upper and lower sides of the connecting pin 33. After the fixing screw 36 passes through the counterbores, it is in threaded cooperation with the concave seat 31, thereby strengthening the concave seat 31.

[0041] Further, one surface of the cabinet door 2 close to the cabinet body 1 is provided with a rounded corner structure 24. So as to avoid interference with the side surface of the cabinet body 1 when opening and closing the cabinet door 2, and prevent the cabinet door 2 from being blocked when opening and closing and rotating.
