Abstract

The utility model discloses a high -voltage board cabinet door structure, including door plant and men bian, the shaping is bent backward on the four sides edge of door plant in the door limit, the qi men limit is on a parallel with the door plant and bends the shaping inwards and have the first limit of bending, the shaping is bent inwards to the first limit perpendicular to door plant of bending there is the second limit of bending, the second is bent the limit and is on a parallel with the door plant and bends the shaping outwards and have the third limit of bending, it is unanimous that the width AND gate hem width degree on limit is bent to the second, the third bends that the door plant is hugged closely on the limit and through rivet and door plant fixed connection, the structural strength height has, firm reliable characteristics when installing and use, high -voltage board cabinet door current has at present been solved by the steel plate stamping shaping of bending, high -voltage board cabinet door structure is thin at the in -service use in -process, intensity is low, the problem of the unable strength requirement that satisfies the production transportation and use.

Description

High-voltage cabinet door

Technical field

This utility model relates to technical field of electric equipment, is specifically related to the cabinet door structure of a kind of high-voltage board.

Background technology

Current existing conventional high-voltage cabinet door is as shown in Figure 1, by steel plate punched bending and molding, its steel plate bending limit is consistent with steel plate body thickness, high-voltage cabinet door side is hingedly fixed on high-voltage board cabinet in use, actually used process mesohigh cabinet cabinet door structure is thin, intensity is low, high-voltage cabinet door even can be shaken when opening and closing, it is impossible to meets the requirement of strength of production and transport and use.

Summary of the invention

For the deficiencies in the prior art, this utility model aims to provide that a kind of structural strength is high, high-voltage cabinet door solid and reliable when installing and using.

For achieving the above object, this utility model adopts the following technical scheme that

High-voltage cabinet door, including door-plate and Men Bian, door limit roll forming folded back upon is on four edges, limit of door-plate, described door limit is parallel to door-plate bending and molding inwardly the first bending edges, first bending edges is perpendicular to door-plate bending and molding inwardly the second bending edges, second bending edges is parallel to door-plate bending and molding outwardly the 3rd bending edges, and the width of the second bending edges is consistent with door hem width degree, and the 3rd bending edges is close to door-plate and is connected by rivet and door-plate are fixing.

Further, described first bending edges forms seal groove, in seal groove, is equipped with sealing joint strip.

Further, described 3rd bending edges two ends form oblique cutting part, and the mis-cut angle of this oblique cutting part is 45 °.

This utility model has the advantages that

This utility model high-voltage cabinet door, Qi Men limit is parallel to door-plate bending and molding inwardly the first bending edges, first bending edges is perpendicular to door-plate bending and molding inwardly the second bending edges, second bending edges is parallel to door-plate bending and molding outwardly the 3rd bending edges, 3rd bending edges is close to door-plate being fixed by rivet and door-plate and is connected, and has structural strength height, a feature solid and reliable when installing and using.

Detailed description of the invention

Below in conjunction with drawings and the specific embodiments, the utility model will be further described, in order to clearer understand this utility model claim technological thought.

This utility model high-voltage cabinet door as shown in Figure 2, including door-plate 1 and Men Bian 2, door limit 2 roll forming folded back upon is on four edges, limit of door-plate 1, door limit 2 is parallel to door-plate 1 bending and molding inwardly the first bending edges 21, first bending edges 21 is perpendicular to door-plate 1 bending and molding inwardly the second bending edges 22, second bending edges 22 is parallel to door-plate 1 bending and molding outwardly the 3rd bending edges 23, the width of the second bending edges 22 is consistent with door limit 2 width, and the 3rd bending edges 23 is close to door-plate 1 and is connected by rivet is fixing with door-plate 1.

The sealing property good for ensureing cabinet door structure, the first bending edges 21 forms seal groove, is equipped with sealing joint strip 211 in seal groove.

For ensureing that between the 3rd bending edges 23, splicing is neat, the 3rd bending edges 23 two ends form oblique cutting part 231, and the mis-cut angle of this oblique cutting part 231 is 45 °.

Operation principle of the present utility model is: Qi Men limit 2 roll forming folded back upon is on four edges, limit of door-plate 1, door limit 2 is parallel to door-plate 1 bending and molding inwardly the first bending edges 21, first bending edges 21 is perpendicular to door-plate 1 bending and molding inwardly the second bending edges 22, second bending edges 22 is parallel to door-plate 1 bending and molding outwardly the 3rd bending edges 23,3rd bending edges 23 is close to door-plate 1 and is connected by rivet and door-plate 1 is fixing, structural strength height, solid and reliable when installing and using.

For a person skilled in the art, can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within this utility model scope of the claims.
