A hinge fastening hole 29 is provided on the hinge connection portion 26. The axis of the hinge shaft hole 28 is perpendicular to the axis of the hinge fastening hole 29. An articulated limiting portion 30 protrudes from the front end of the hinge body 25.

[0031] The above door hinge can be applied to a disinfection machine. The disinfection machine includes a machine body and a door body. Among them, a fastener is provided on the hinge fastening hole 29 and is fixedly arranged on the machine body through the fastener. An articulated shaft 27 is provided on the door body. The door body is hinged and opened and closed on the machine body through the cooperation of the articulated shaft 27 and the hinge shaft hole 28. When the door body is opened at a certain angle, it is limited on the machine body by the articulated limiting portion 30.

[0032] In this embodiment, a hollow or solid hinge body 25 is used as the core part of the door hinge. At the same time, a hinge fastening hole 29 for assembling with the machine body and a hinge shaft hole 28 for assembling with the articulated shaft 27 are provided on the hinge connection portion 26 of the hinge body 25. The articulated shaft 27 is also connected in cooperation with the door body, so as to realize the articulated cooperation between the machine body and the door body. In addition, since the axis of the hinge shaft hole 28 is perpendicular to the axis of the hinge fastening hole 29, after the door body is assembled, its gravity can be well dispersed to the hinge body 25 and the machine body, which not only effectively improves the overall structural strength of the door hinge, but also can avoid problems such as fracture of the door hinge, or shaking, dropping, and falling of the door body after the door body is opened, ensuring the safe use of the disinfection machine.

[0033] Specifically, the interior of the hinge body 25 is hollow and forms a hinge cavity 31. A hinge reinforcing rib 32 is provided in the hinge cavity 31, and a hinge end opening 33 is provided at the rear end of the hinge body 25 corresponding to the hinge cavity 31.

[0034] In this embodiment, the hinge body 2 is hollow, which can reduce the production materials of the door hinge and lower the production cost. At the same time, by utilizing the strengthening effect of the hinge reinforcing rib 32, problems such as deformation and fracture of the hinge body 25 can be avoided. Additionally, the setting of the hinge end opening 33 can further reduce the production materials of the door hinge and is also beneficial to the production and processing of the door hinge.

[0035] The hinge end opening 33 protrudes with a hinge opening edge 34 towards the rear of the hinge connection part 26.

By adopting this arrangement, the positioning of both sides of the hinge body 25 can be facilitated, and it is also beneficial for the fastener to act on the hinge fastening hole 29. Additionally, during the assembly of the hinge body 25, it can be positioned through the hinge opening edge 34, thereby improving the assembly accuracy of the door hinge.

[0037] The front end of the hinge body 25 is further provided with a hinge flat part 36 and a hinge arc part 37 connected end to end. The hinge arc part 37 is arranged on the same side as the hinge fastening hole 29, and the hinge limit part 30 protrudes on the hinge flat part 36.

[0038] In this embodiment, during the opening and closing process of the door body, its side will be guided along the trajectory of the hinge arc part 37, thereby improving the stability and smoothness of the hinge opening and closing of the door body. When the door body is opened to the terminal position, its side will be positioned on the hinge limit part 30, thereby avoiding the problem of the door body retreating after being opened and ensuring the stable opening of the door body.

[0039] A hinge groove 38 is further provided on the side of the hinge body 25, and the hinge groove 38 linearly extends between the hinge shaft hole 28 and the hinge flat part 36.

[0040] In this embodiment, the setting of the hinge groove 38 can further reduce the production materials of the door hinge. Additionally, since the hinge groove 38 is located between the hinge shaft hole 28 and the hinge flat part 36, users can place lubricating oil on the hinge groove 38 so that the lubricating oil enters the hinge shaft hole 28 through the hinge groove 38, thereby reducing the friction between the hinge shaft 27 and the hinge shaft hole 28 and improving the smoothness of the hinge opening and closing of the door body.

[0041] One or more hinge reinforcing ribs 32 are provided and are arranged longitudinally, and / or transversely, and / or obliquely within the hinge cavity 31.

[0042] In this embodiment, two hinge reinforcing ribs 32 are provided and are respectively arranged longitudinally and transversely within the hinge cavity 31, so as to support the longitudinal and transverse positions inside the hinge cavity 31, thereby greatly improving the structural strength of the hinge body 25.
