The bearing-free drawer structure of the traditional low-voltage draw-out type switch cabinet is as follows: the granted publication number is "CN 212011759U", the name is "a drawer structure of drawer cabinet" Chinese utility model patent shows. The sliding rail assembly usually comprises a C-shaped rail and an L-shaped rail, the C-shaped rail is arranged on a bearing plate of the cabinet body, the L-shaped rail is arranged on two sides of a drawer, and then one side of the L-shaped rail is inserted into a sliding groove of the C-shaped rail to realize sliding fit. There are disadvantages in that: the stress points of the rails with the structure are concentrated on the transverse side edges of the L-shaped rails, and the L-shaped rails are very heavy after the electric appliance elements are arranged in the drawer, so that the L-shaped rails are easily deformed, and the drawer cannot normally slide; in addition, the whole side surface of the L-shaped track is contacted with the step on the C-shaped track, so that the resistance is large, and the sliding of the drawer is not smooth enough.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a bearing capacity is better, slide more smooth and easy low pressure pull-out type cubical switchboard.

In order to solve the above problem, the utility model discloses a technical scheme include: the cabinet body, drawer, the drawer is installed through the sliding rail set slidable of two ends the cabinet is internal, its characterized in that: the sliding rail assembly consists of a first rail and a second rail, the first rail is arranged on two sides of the cabinet body and comprises a base plate, an upright post and a cross beam, the base plate is integrally formed, the upright post is arranged in the middle of the base plate, the cross beam is arranged at the upper end of the upright post, a sliding groove is formed between the cross beam and the base plate, and the upper ends of the upright post and the cross beam are respectively provided with a protruding part supported at the bottom of the drawer; the second rails are arranged on two sides of the drawer and are L-shaped; the front end of the second track extends into the sliding groove.

The low-voltage draw-out type switch cabinet is characterized in that: the tip of bellying is equipped with first arcwall face.

The low-voltage draw-out type switch cabinet is characterized in that: the front end of the second track is provided with a second arc-shaped surface, and the second arc-shaped surface is close to the upright post of the first track.

The low-voltage draw-out type switch cabinet is characterized in that: and at least one group of mounting holes is arranged on the inner side surface of the bottom plate.

The low-voltage draw-out type switch cabinet is characterized in that: the second rail is formed by integrally bending the lower ends of the side plates of the drawer.

The low-voltage draw-out type switch cabinet is characterized in that: the cabinet body is provided with a bearing plate, and the first rail is installed on the bearing plate.

The utility model discloses a low pressure pull-out type cubical switchboard advantage as follows: stress points are concentrated on the upright post and the cross beam of the first track, and the bearing capacity of the longitudinal upright post is far greater than that of the traditional transverse side edge, so that the compression resistance of the slide rail is greatly improved; in addition, two arc-shaped surfaces are adopted to be contacted with the bottom of the drawer, and the upright post of the first rail of one arc-shaped surface is contacted, so that the structure is stable, the friction force is very small, and the drawer can slide very smoothly.

The present invention will be further explained with reference to the drawings attached to the specification.
