Cabinet front door frame and front door and cabinet with the frame

Abstract

The invention relates to a frame for a cabinet and a front door, and the front door and the cabinet with the frame. The frame for the cabinet and the front door comprises a left upright post, a right upright post, an upper beam and a lower beam, wherein grooves which extend along the length directions of the upright posts and are used for installing glass are formed in the left upright post and the right upright post; and the upper beam and the lower beam are fixedly arranged on the rear end surfaces of the left upright post and the right upright post, so that the upper surfaces and the lower surfaces of the upper beam and the lower beam are flush with the upper end surfaces and the lower end surfaces of the left upright post and the right upright post respectively, and are flush with the upper edge and the lower edge of the glass. The problems that the overall frame is not good enough in permeability and not beautiful due to the fact that the beams are arranged in front of the glass and shield one part of glass in the prior art are overcome. Glass cover boards are arranged on the upper surface of the upper beam and the lower surface of the lower beam respectively; and glass block edges attached to the front surface of the glass are arranged on the glass cover boards, so that the edges of the glass are protected; and the edges of the glass are relatively sharp, are free of a fragile part, do not easily cut a person and are not easy to be broken.

Description

technical field [0001] The invention relates to a front door frame of an industrial cabinet and a front door and a cabinet with the frame. Background technique [0002] In the prior art, the front doors of industrial cabinets are mostly formed by bending cold-rolled steel plates, or are bent and formed by cold-rolled steel plates, and then equipped with glass observation windows, or are installed with sheet metal welded door frames, and the hinge connection methods are mostly Welding type, and the locking system is mostly connected by additional screws. Generally, there are five problems: 1. It cannot better meet the user's requirements for both the strength of the door panel and the permeability requirements for timely and convenient observation. ;2. The overall appearance of the door panel is low-grade and unattractive; 3. The welded door frame deforms a lot, resulting in the added glass observation window being easily broken, with low yield and low production efficiency, ...

Problems solved by technology

[0002] In the prior art, the front doors of industrial cabinets are mostly formed by bending cold-rolled steel plates, or are bent and formed by cold-rolled steel plates, and then equipped with glass observation windows, or are installed with sheet metal welded door frames, and the hinge connection methods are mostly Welding type, and the locking system is mostly connected by additional screws. Generally, there are five problems: 1. It cannot better meet the user's requirements for both the strength of the door panel and the permeability requirements for timely and convenient observation. ;2. The overall appearance of the door panel is low-grade and unattractive; 3. The welded door frame deforms a lot, resulting in the added glass observation window being easily broken, with low yield and low production efficiency, which cannot be quickly delivered to users; ;4 . The hinge welding position error is large, and the door panel is not easy to be installed on the cabinet frame smoothly; 5. The installation and connection of the door panel locking system is cumbersome, and the assembly efficiency is low

like figure 1 As shown, the current cabinet front door is mainly composed of two left-right symmetrical columns 22 and a door frame formed by beams 24 at both ends of the two columns 22, and a glass 23 installed on the door frame. figure 2 It is a schematic diagram of the combination structure at the corner of the front door of the existing cabinet. When assembling the door frame, firstly, the upright column 22 and the connection angle 27 are fixed and formed with screws, and then the connection angle 27 is connected with the beam 24 with screws. The installation process is complicated, and the beam 24 and the beam 24 are connected together. After the column 22 is connected, it blocks the front of the glass 23, resulting in poor overall glass permeability and unsightly appearance.
