Switch cabinet drawer

Abstract

The invention discloses a switch cabinet drawer. The switch cabinet drawer comprises a drawer bin; a drawer is arranged in the drawer bin in a sliding manner; a drawer panel is provided with an operation knob used for controlling the on-off of a component in the drawer; a mounting seat is arranged in the drawer; an interlocking mechanism which rotates along with the operation knob to limit the sliding of the drawer is arranged on the mounting seat; and a display mechanism which displays the state positions of the drawer according to the movement of the drawer is arranged on the mounting seat.The switch cabinet drawer can satisfy use requirements when being in three state positions; the switch cabinet drawer is simple in structure and is convenient to process and product; and the overallstructure of the display mechanism is more stable.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, in particular to an interlocking device for a drawer of a switch cabinet drawer. Background technique [0002] The drawer compartment of the switch cabinet is a kind of electrical equipment. There are movable drawers on the drawer compartment of the switch cabinet, and different circuit controllers are installed in each drawer, so that the circuit is controlled by the drawer compartment of the switch cabinet. At the same time, the drawer of the switch cabinet is usually There are three different special state positions, which are separation position, test position and connection position. The separation position is the position where the circuit is completely disconnected. In this position, the drawer of the switch cabinet drawer can be pulled out to check the components in the drawer. and circuit maintenance operations to avoid danger; in the test position, the circuit of the device...

Problems solved by technology

[0002] The drawer compartment of the switch cabinet is a kind of electrical equipment. There are movable drawers on the drawer compartment of the switch cabinet, and different circuit controllers are installed in each drawer, so that the circuit is controlled by the drawer compartment of the switch cabinet. At the same time, the drawer of the switch cabinet is usually There are three different special state positions, which are separation position, test position and connection position. The separation position is the position where the circuit is completely disconnected. In this position, the drawer of the switch cabinet drawer can be pulled out to check the components in the drawer. and circuit maintenance operations to avoid danger; in the test position, the circuit of the device is partially turned on, which can be used as a test circuit, also called the test state, and the drawer is not allowed to be pulled out in this position; the on position indicates this position In this state, the circuit is in a state that can be fully connected to work, and can work normally after closing, which is also called the working position. In this state, the drawer is locked and cannot be pulled out; therefore, it is necessary to design an interlocking device to ensure that it is in this state. The lock of the drawer in the three-seat state, but the existing drawers have various models, such as 1 / 2 drawer size model, 1 / 4 drawer size model and full drawer size model. These different types of drawers also need to be installed in different structural forms Interlocking mechanisms, these interlocking mechanisms have complex structures, resulting in low production and processing efficiency and increased production costs. At the same time, in order to cooperate with the locking, it is also necessary to design a display mechanism to timely indicate the state and position of the drawer cabinet, which is convenient for the operator to observe. However, the existing When the display mechanism is in use, it is easy to deviate due to the vibration of the switch cabinet, which leads to inconvenient observation and is not conducive to improving the use efficiency
