Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.
Structure of the present utility model expressed by Fig. 1 to Fig. 9, for a kind of low-voltage cabinet wears cabinet door fixed hinge structure, is suitable for the fixing of Hinge for cupboard door in low-tension switch cabinet, to solve in current low voltage complete set produced problem in hinges fixing definite form.It comprises hinge fixed bearing 10, hinge rotary support 5, and both is connected by hinge pin 9, and described hinge fixed bearing 10 is fixed on the cabinet of switchboard.
For the door-plate that appearance and size is less, hinge rotary support 5 can be installed in advance by hinge pin 9 and hinge fixed bearing 10, and then carry out fixing of hinge and door-plate, effectively can reduce the assembly space of bearing pin.
In order to solve prior art Problems existing and overcome its defect, realize the goal of the invention of the installation accuracy improving hinge, the technical scheme that the utility model is taked is:
As shown in Figures 1 to 9, door hinge of switch cabinet of the present utility model, described hinge rotary support 5 is fixed on door-plate 4 inner surface by screw 2, and is hidden by connecting portion on the external surface of described door-plate 4 by decoration panel 1.
Structure of the present utility model is simple, is convenient to install, and improves hinge installation accuracy hinge arrangement form.Utilize the leftover pieces produced in producing to make, improve stock utilization, reduce cost of production.
The described connected mode of hinge rotary support 5 on door-plate 4 is: on the external surface of door-plate 4, arrange rotary support fixed head 3, the threaded portion of described screw 2, successively through rotary support fixed head 3, door-plate 4, hinge rotary support 5, screws in nut 8 at the threaded portion of screw 2 and carries out fastening.
Rotary support fixed head 3, hinge rotary support 5, hinge fixed bearing 10 all can process by mould punching, and plate is less, the leftover pieces produced in production can be utilized to make, improve stock utilization, reduce cost of production.
On described screw 2, from hinge rotary support 5 to nut 8, be set with plain washer 6 and elastic washer 7 successively.
As shown in Figure 7 to 9:
Described hinge rotary support 5, towards the one side of door-plate 4, arranges rotating seat positioning boss 11, and the relevant position on described door-plate 4 arranges locating hole, and described rotating seat positioning boss 11 is formed with described locating hole and coordinates.
Described rotary support fixed head 3, towards the one side of door-plate 4, arranges rotating seat fixed head positioning boss 12, and the relevant position on described door-plate 4 arranges locating hole, and described rotating seat fixed head positioning boss 12 is formed with described locating hole and coordinates.
In hinge installation process, by the hinge rotary support 5 with rotating seat fixed head positioning boss 12 and the rotary support fixed head 3 with rotating seat positioning boss 11, be fixed on the stationary positioned hole that door-plate 4 leaves by M6 sunk screw 2, plain washer 6, spring washer 7, nut 8.
