Description

This utility model relates to the field of electrical engineering, namely to the designs of cabinets designed for the distribution and management of electricity in various industries.

For the safe operation of control cabinets, a reliable locking system for its doors is required. The reliability of the locking system of the cabinet door depends on the centering and adjustment of the locking elements, the correct positioning of the moving and locking elements located on the door and the cabinet shell.

The hinged door fastening, often used on control cabinets, has certain play. The designs of enclosures and doors of control cabinets have limited rigidity, due to the purpose of the design, increased rigidity leads to an undesirable increase in production costs. Control cabinet doors, monitors, and other electrical equipment of control cabinets, which give a serious load to the door, are often located on the doors of control cabinets. This leads to sagging doors, the displacement of the elements of the locking system located on the door relative to the elements located on the body. As a result, closing and locking the door becomes difficult and not reliable, which is unsafe for the operation of the control cabinet.

The technical solution of ALUTECH company is known, in the catalog http://alutech-group.com/upload/iblock/6bf/tk-vs-trend-ru-280916.pdf, p. 86 - “trap” and “trap support” for the gate. This technical solution uses a flat part "trap" with a tapering slot and going into the slot "support of the trap", which is a sleeve or bearing. The capture occurs due to the rolling or sliding of the support on the surface of the slot of the trap.

A limitation of this solution is protection only against sagging doors and the lack of positioning in the horizontal plane. According to the operating experience of the control cabinet door, it is possible not only to sag the door (displacement of the contact plane in the vertical plane), but also to skew or tilt the door (displacement in both the vertical and horizontal planes). The inventive utility model solves the issue of positioning the door at any displacement during operation.

The claimed technical solution is aimed at creating a simple and inexpensive in industrial production system of elements for positioning the door of the control cabinet, acting when it is locked and preventing the displacement of the door during operation of the control cabinet.

The design of the proposed technical solution is shown in the drawings, which depict:

FIG. 1 - shell and door of the control cabinet, general view;

FIG. 2 - door and shell elements of the control cabinet, section, top view;

FIG. 3 - options for the location of the guide and positioning elements on the bending of the door and the shell of the control cabinet, section, top view;

FIG. 4 - the interaction of the guiding and positioning elements when closing the door;

Designations:

1 - cabinet enclosure;

2 - the door of the control cabinet;

3 - hinged door;

4 - U-shaped bending of the door of the control cabinet;

5 - the surface of the enclosure of the control cabinet adjacent to the bending of the door;

6 - a directing element;

7 - positioning element.

The claimed technical solution can be implemented in the design of the shell of the control cabinet containing at least one door with hinge fastening and shell elements of the control cabinet.

The enclosure of the control cabinet with the door and structural elements is arranged and operates as follows.

The shell of the control cabinet 1 with structural elements contains at least one door 2 (Fig. 1) with hinge fastening 3. The doors 2 are made with a U-shaped bend 4 adjacent to the surface 5 of the shell of the control cabinet 1 (Fig. 2).

On one of the surfaces adjacent to each other when closing the door (the folding surface of the door 4 or the adjacent surface 5 of the shell 1 of the control cabinet), guide elements 6 are made in the form of a cone placed on the cylinder.

On the opposite surface, positioning elements 7 are made with an opening in the form of a ring with a tapering round hole so that when closing the door, the guiding elements 6 pass through the holes of the elements 7. Due to the conical part of the guiding elements 6 and the toroidal shape of the opening of the positioning elements 7, when closing the door 2, phased capture and smooth centering of the axes of the elements 6 and 7 relative to each other.

When the door is further closed, the cylindrical part of the guide elements 6 moves linearly in the hole of the positioning elements 7. This ensures the correct position of the door 2 relative to the enclosure of the control cabinet 1 provided by the design, which allows any type of locking system to reliably and easily lock the control cabinet door.

The shape of the surfaces of the guide elements 6 and the positioning elements 7 provides smooth sliding, facilitates closing the door and allows you to position the door with significant sagging or other displacement. Positioning elements are simple in industrial production and can be made of various materials.

The operation of the system of elements occurs in the same way, regardless of which of the elements are made on the surface of the folding door, provided that elements of a different type are made on the adjacent surface of the enclosure of the control cabinet. This allows you to choose a convenient design solution for a particular cabinet design.

Thus, the application of the utility model improves the reliability of locking the door, further facilitating the closing of the door during operation of the control cabinet.

Claims (1)

A cabinet enclosure containing at least one door, on the perimeter of which a U-shaped folding is made adjacent to the cabinet enclosure when closing the door, characterized in that at least one cone-shaped guide element is made on one of the adjacent surfaces of the folding door or cabinet enclosure, set on the cylinder, with at least one positioning element with an opening of variable circular cross section of decreasing diameter being made on the opposite adjacent surface so that closing door guide member passes through the hole of the positioning member first conical and then cylindrical part, performing a positioning closable cabinet door relative to the shell.
