Technical Field

The utility model relates to a technical field of automatically controlled cabinet, concretely relates to low pressure pull-out type cubical switchboard.

Background

The low-voltage switch cabinet is suitable for industries such as power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and the like, and is used for power transmission, power distribution and electric energy conversion. The low-voltage switch cabinet can be structurally divided into a fixed type and a draw-out type, wherein the draw-out type is composed of a fixed cabinet body and a movable drawer provided with main electrical elements such as a switch and the like, and the disassembly, the movement and the repair of the electrical elements can be facilitated. The drawer of cubical switchboard is similar with conventional drawer, and the length that the drawer of general cubical switchboard was taken out from the cabinet body is limited, and partial length of drawer still is located the cabinet internally, and this can cause inconvenience to the wiring work of the innermost in the drawer, and when the drawer was taken out to the extreme position outside the cabinet body, the drawer was relatively poor with the be connected steadiness of the cabinet body, and its connection site produces the rupture easily.

SUMMERY OF THE UTILITY MODEL

To the deficiency that prior art exists, the utility model aims to provide a low pressure pull-out type cubical switchboard, the drawer is when can taking out completely from the cabinet body, and the drawer is difficult for the rupture damage with the hookup location of the cabinet body.

The utility model adopts the technical proposal that:

the utility model provides a low pressure pull-out type cubical switchboard, includes the cabinet body, sets up a plurality of drawer cavitys and the slip on the cabinet body set up in drawer in the drawer cavity, the both sides of drawer cavity are equallyd divide and do not are provided with movable pivot, fixedly connected with guide rail strip in the activity pivot, the middle part of guide rail strip is provided with the slide rail, the both sides of drawer equally divide do not be provided with slide rail sliding fit's bump, the rear portion of drawer is provided with the step cell body, the step cell body with the turning of drawer cavity's front end lower part cooperatees.

Furthermore, a plurality of rollers are arranged on the front side face of the step groove body and are arranged along the longitudinal direction, and oblique guide blocks are fixedly arranged at the bottom of the step groove body and are arranged below the rollers.

In the scheme, the roller is designed to ensure that the drawer can stably move downwards by virtue of the rolling of the roller when the drawer is completely pulled out until the step groove body is abutted against the corner at the lower part of the front end of the drawer cavity; the oblique guide block is designed to ensure that the corner of the lower part of the front end of the drawer cavity can be better transited from the drawer to the roller wheel in the drawer drawing process.

Furthermore, a front plate is arranged on the front end face of the drawer, the width of the front plate is larger than that of the drawer, and the front plate is matched with the drawer cavity.

In the above scheme, the front plate is matched with the drawer cavity, and the front plate completely seals the opening of the drawer cavity when the drawer is pushed in.

Furthermore, the vertical distance between the center of the salient point and the bottom of the drawer is equal to the vertical distance between the center of the movable rotating shaft and the bottom of the drawer cavity.

In the scheme, the two vertical distances are equal, and the guide rail bar can be ensured to be in a horizontal state in the drawer push-pull process, so that the drawer is pushed and pulled respectively.

The utility model has the advantages that: the guide rail bar can rotate freely, the salient points are matched with the sliding rails to enable the drawer to be drawn out completely, when the drawer is drawn out of the cabinet body completely, the step groove body of the drawer is abutted against the corner of the lower portion of the front end of the drawer cavity, the drawer is in a lifted state, stress at the salient points is greatly reduced, and therefore the guide rail bar is not prone to being broken or damaged; because the drawer completely slides out of the cabinet body, the maintenance, the disassembly and the assembly of circuits and elements in the drawer are more convenient for workers.
