Description

Switch cubicle hinge structure

Technical field

The utility model belongs to the cabinet door installing area of cabinet, is specifically related to a kind of switch cubicle hinge structure.

Background technology

The cabinet door of cabinet plays the effect of covering the cabinet inner chamber, need often open or close in use, so require cabinet door and cabinet to cooperate closely, the cabinet door rotates flexibly.Traditional cabinet cabinet door, its latch and cabinet door adopt Welding Structure, can bring following problem for this reason: 1, the welding slag of latch and cabinet door welding is not easy to remove, and is difficult to the location accurately during welding, causes left and right sides door-plate installation asymmetric; Easy deformation when 2, latch welds causes door-plate that difficulty is installed; 3, switch cubicle hinge position is the significant points of cabinet door grounded circuit, and since door-plate and latch weld and be fixed as one, latch must be with lacquer when door-plate sprayed paint, when door-plate is installed, latch needs thorough coating removal, door-plate could be installed, otherwise causes door-plate ground connection property poor, but the thorough coating removal of latch is again very to bother; 4, cabinet door unlatching resistance is big, and dismantles, keeps in repair trouble; 5, being connected of hinge and cabinet column adopted two bolts, because 2 be difficult to determine a plane, thereby door-plate rocks when rotating big.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of switch cubicle hinge structure is provided, and need not weld between its cabinet door and the latch, and the cabinet door is installed, convenient disassembly, rotates flexibly.

Its purpose can realize by following scheme: this switch cubicle hinge structure comprises cabinet, cabinet door, and first hinge plate, second hinge plate, hinge, cabinet is provided with column in the position near hinge, its main feature is, first hinge plate comprises substrate and flanging, substrate and flanging are integrally formed, and plane, flanging place and plane, substrate place are orthogonal; The substrate of first hinge plate is fixedlyed connected with column, and the cabinet door is fixedlyed connected with second hinge plate; The flanging of first hinge plate is terminal to curl, and the terminal middle part of the first hinge plate flanging forms breach, and the flanging end that wherein is positioned at above the breach curls into first jack, and the flanging end that is positioned at below the breach curls into second jack; The terminal breach that embeds first hinge plate flanging end middle part of second hinge plate, and the second hinge plate end curls into the 3rd jack; First jack, second jack, the 3rd jack are located along the same line; Hinge is the L shaped of handstand, and hinge is inserted in first jack, second jack, the 3rd jack.

Be preferably, the substrate of first hinge plate adopts three screw to be connected with column, and three screws are not on same straight line.

Be more preferably cabinet door and the welding of second hinge plate.

The utlity model has following advantage and effect:

1, the L shaped hinge that adopt to stand upside down of the utility model is inserted in three jacks, need not weld between hinge and the cabinet door, and the setting height(from bottom) of cabinet door can finely tune according to the cooperation needs of cabinet, and the setting height(from bottom) of cabinet door can not be subjected to the influence of welding slag; Latch is not yielding; Make cabinet door installation accuracy height, favorable sealing property between cabinet door and the cabinet, the cabinet door rotates flexibly, also realizes left and right sides door-plate installation symmetry easily.

2, the cabinet door is opened conveniently, and repair demolition is simple, takes off hinge axis, and the cabinet door is separated with cabinet.

3, the utility model adopts three planes of not determining the first hinge plate substrate place at collinear bolt, has solved the traditional structure door-plate and has occurred the phenomenon of rocking easily, more helps making favorable sealing property between whole cabinet door and the cabinet.

4, need not weld between cabinet door of the present utility model and the latch, solve traditional welding structure welding slag that is produced and the quality problems of spraying paint and being left over, improve door-plate ground connection performance, and simplify installation procedure.
