Description

Technical Field

[0001] The present application relates to the field of switch cabinet technology, and in particular to a low-voltage drawer-type switch cabinet. Background Art

[0002] Low-voltage drawer switch cabinet is a low-voltage switch distribution control panel, equipped with low-voltage switch group, circuit protection system, etc. Low-voltage drawer switch cabinet is suitable for power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other industries for power transmission, distribution and power conversion. The switch cabinet drawer is generally slidably set on the guide rail, in which the guide rail is fixedly connected to the side wall of the concave cavity of the low-voltage drawer switch cabinet.

[0003] Common low-voltage switch cabinets often adopt a step-by-step assembly method for various components. Generally, two pieces or left and right sides are first assembled, and then the cabinet body is assembled, or the appearance requirements are met first, and then the internal supports of the cabinet body are connected in sequence. When the number of drawers in the switch cabinet is large, if the drawer installation structure is complicated, it will require installers to install many steps, which will be time-consuming and labor-intensive. Utility Model Content

[0004] In order to simplify the installation of a switch cabinet drawer, the present application provides a low-voltage drawer-type switch cabinet.

[0005] The present application provides a low-voltage drawer-type switch cabinet, which adopts the following technical solution:

[0006] A low-voltage drawer-type switch cabinet comprises a switch cabinet body and a plurality of drawers, wherein the switch cabinet body is surrounded by a cavity, and a partition is arranged on the switch cabinet body, and the partition divides the cavity into a plurality of parts, and the partition is located at the bottom of the drawer, and the partitions are arranged one by one corresponding to the drawers, and slide bars are arranged on opposite sides of the partition bar, and a plurality of positioning pieces are arranged at the bottom of the slide bar, and a plug-in groove for the positioning piece to be plugged in is provided on the partition bar, and a slide plate is slidably arranged on the slide bar, and the slide plate slides along the length direction of the slide bar, and a bottom plate is arranged between two of the slide plates, and the two ends of the bottom plate are respectively arranged on the sides of the slide plate, and the bottom plate is provided with a plurality of line holes for the lines to pass through.

[0007] By adopting the above technical solution, during installation, the partition is first installed, the upper slide bar is inserted, the slide plate is slidably set in the slide bar, and the bottom plate is installed to complete the installation, and the switch cabinet drawer is easy to install.

The limiting column passes through the limiting groove. A cylindrical barrel is provided at one end of the limiting column away from the limiting plate. The outer diameter of the cylindrical barrel is smaller than the outer diameter of the limiting column. A limiting hole for the cylindrical barrel to pass through is provided on the sliding plate. When the cylindrical barrel abuts against the side surface of the convex block, the compression spring is compressed, and the limiting plate slides in a direction away from the convex block; when the cylindrical barrel is away from the convex block, the compression spring resets, and the limiting plate slides in a direction close to the convex block.

[0015] By adopting the above technical solution, the limiting component reduces the installation accuracy when the switch cabinet is closed. The compression spring sleeved on the fixing column can abut against the convex block according to the installation position, and the compression spring resets when away from the convex block.

[0016] Optionally, the convex block is provided with a chamfer.

[0017] By adopting the above technical solution, the chamfer enables the cylindrical barrel to better abut against the convex block.

[0018] Optionally, a clamping post is provided on the sliding plate close to the sliding bar, and an elastic sleeve is sleeved on the clamping post.

[0019] By adopting the above technical solution, the elastic sleeve has the effect of reducing buffering during vibration, preventing damage to electrical components caused by the vibration of the switch cabinet.
