Technical Field

The invention relates to the technical field of power distribution cabinets, in particular to a section bar and a three-door power distribution cabinet body.

Background

Switch board compact structure, inside electrical components is many, for the dust that prevents in the air gets into the inside life who influences electrical components of switch board, domestic switch board manufacturer utilizes the nine book section bar to adopt outer column structural design switch board, the protection level of the switch board of this kind of structure can reach IP55, but the switch board that adopts the nine book section bar all is singly opened the door, after the electrical components installation of the inside of switch board and wiring work completion, the left side of switch board, right side and rear side utilize the backplate to encapsulate usually, it is inside to prevent that the dust in the air from getting into the switch board. But the single-door power distribution cabinet, especially single-door single power distribution cabinet, has limited internal space, and is not favorable for installation and wiring and daily maintenance of electrical components of the power distribution cabinet.

Disclosure of Invention

In order to solve the problem that a single-door power distribution cabinet in the prior art is not beneficial to installation and wiring of electrical elements of the power distribution cabinet and daily maintenance, the invention provides a section bar, and a three-door power distribution cabinet body maintained by the power distribution cabinet is manufactured by utilizing the section bar.

The technical scheme adopted by the invention for solving the technical problems is as follows:

the utility model provides a section bar, includes first folded plate and second folded plate, first folded plate buckle into the right angle folded plate, the second folded plate buckle into the W folded plate that appears, the both sides tip of right angle folded plate inwards bend into borduring, the section of bending at W shape folded plate both ends laminate with two sections of bending of right angle folded plate respectively, and the partly of the section of bending at W shape folded plate both ends is located borduring at first folded plate both ends respectively.

Furthermore, the bending angles of the W-shaped folded plates are all 90 degrees.

Furthermore, the end part of the edge of the right-angle folded plate is in a square tooth shape or a sawtooth shape.

Furthermore, two right angle sections of the first folded plate are provided with module holes, and the module holes comprise square holes and/or round holes which are arranged at intervals.

The utility model provides a three switch board cabinets bodies, includes the frame, the frame include four vertical stands, be fixed with the back timber between the adjacent stand, wherein three side-mounting of the cabinet body has the cabinet door, the cabinet door is articulated with the stand that corresponds the position, another side-mounting has the backplate on the cabinet body, stand and/or back timber adopt as above the section bar.

Furthermore, the cabinet door is connected with the upright post through a hinge, one end of the hinge is fixed on a certain folding section in the middle of the W-shaped folding plate, and the other end of the hinge is fixed with the cabinet door.

Further, a polyurethane gluing foaming sealing strip is fixed on the cabinet door, and when the cabinet door is closed, the polyurethane gluing foaming sealing strip is pressed against the edge of the first folded plate at the corresponding position.

Furthermore, a side beam is fixed between the adjacent upright columns, and the end part of the side beam is matched with the modulus hole of the second folded plate.

Furthermore, the side cross beams, the top beams and the upright posts are all made of the profiles.

Furthermore, the upright posts are connected with the top beams on the two sides through tee joints.

Has the advantages that:

(1) the section structure can realize the installation of three doors;

(2) the edge of the right-angle folded plate of the profile is in the shape of square tooth or sawtooth, so that when external force is applied to a certain position of the edge of the right-angle folded plate, the edge of the right-angle folded plate only can be lifted locally at the stressed position and is lifted to the root of the tooth at most, but not lifted integrally, and the structural stability of the upright post or the top beam is improved;

(3) the two right-angle folding sections of the second folding plate are provided with modulus holes, so that the second folding plate can be conveniently connected with other sectional materials.

(4) Although the protection level of IP55 can be accomplished to current switch board, because the structural problem of section bar, only can do the design of singly opening the door. On the premise of ensuring the protection grade IP55, the invention can realize three-door, the design of the three-door greatly improves the maintenance efficiency of the power distribution cabinet, and the specific mode of the protection grade IP55 of the invention is realized as follows: when the door is closed, the edge of the section bar can press the polyurethane gluing foaming sealing strip on the door plate to form sealing.
