CN202474588U - Door pivot for distribution cabinet - Google Patents

Abstract

The utility model discloses a door pivot for a distribution cabinet. The door shaft comprises a first iron sheet with a bending angle of 90 degrees, wherein one end of the first iron sheet is vertically connected with a second iron sheet; a first through hole is formed on the other end of the first iron sheet; a connecting sheet is vertically arranged on the second iron sheet; and a second through hole is formed on one end of the connecting sheet. Because the door pivot is installed on the distribution cabinet, a large angle can be obtained when a door plate is opened. In addition, the door pivot is convenient in replacement.

Description

A door shaft of a power distribution cabinet

technical field

The utility model relates to a door shaft, in particular to a door shaft of a power distribution cabinet.

Background technique

Power distribution cabinet is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal working conditions. Commonly used in various power generation, distribution and substations.

In addition to the basic information of the power distribution cabinet described above, there are also components such as the fixing plate for fixing various electrical appliances in the power distribution cabinet, the wiring groove for placing wires, the door shaft for connecting the door panel and the box body, etc. These components are all There are certain production requirements, such as the door shaft used to connect the door panel and the box body, one end of the door shaft is connected with the box body, the other end is connected with the door panel, and the two are hinged by a pin to achieve the effect of rotation .

However, the angle of the door hinge on the traditional distribution box is small when the door panel is opened. If the electrical appliances need to be repaired, there is not enough space, which brings inconvenience to the maintenance personnel, and the ordinary door hinge is easy to be damaged under long-term use. The entire door shaft needs to be replaced, which increases the maintenance cost.

Contents of the invention

Aiming at the deficiencies of the prior art, the utility model provides a door shaft of a power distribution cabinet with a large rotation angle and easy replacement.

In order to achieve the above-mentioned technical purpose, the utility model is achieved through the following technical solutions.

A door shaft of a power distribution cabinet, comprising a first iron sheet with a bending angle of 90°, one end of the first iron sheet is vertically connected to a second iron sheet, and the other end of the first iron sheet is provided with a second iron sheet. A through hole, the second iron sheet is vertically provided with a connecting piece, and one end of the connecting piece is opened with a second through hole.

In the above technical solution, there are two connecting pieces provided on the second iron piece.

Compared with the prior art, the utility model has the beneficial effects that: the door shaft is installed on the power distribution cabinet, the angle is larger when the door panel is opened, and it is convenient to replace when damaged.

Description of drawings

Fig. 1 is a schematic diagram of the structure of the door shaft of the utility model installed on the distribution box.

Fig. 2 is an enlarged view of the utility model I place.

Fig. 3 is a structural schematic diagram of the utility model.

Detailed ways

A power distribution cabinet door shaft of the utility model will be further described in detail below in conjunction with the accompanying drawings.

Referring to Fig. 1 to Fig. 3, a door shaft of a power distribution cabinet is installed on a power distribution box. Electrical components 3 are arranged on the back of 2, and electrical components 3 are arranged in the box body 1, wherein there are many types of electrical components 3, such as circuit breakers, transformers, ammeters and so on.

In the above description, in order to make the door panel easy to open and have a large opening angle, it is preferable to include a first iron sheet 4 with a bending angle of 90°, and one end of the first iron sheet 4 is vertically connected to a second iron sheet 5 , the other end of the first iron sheet 4 is provided with a first through hole 6 , the second iron sheet 5 is vertically provided with a connecting piece 7 , and one end of the connecting piece 7 is provided with a second through hole 9 . During installation, it is only necessary to pass the door panel 2 between the connecting pieces 7 through the pin shaft 8, which is simple and convenient.

In order to secure the door panel, preferably, there are two connecting pieces 7 provided on the second iron piece 5 .

According to the above structural description, the door shaft installed between the door panel 2 and the box body 1, when in use, the door panel 2 rotates at a relatively large angle. Specifically, one end of the door shaft is fixed on the box body 1, while the other One end is an active connection.

Moreover, when maintenance is required, the door panel 2 can be taken down only by pulling out the pin shaft 8 hinged on the door shaft, which is convenient and practical.
