Description

Technical Field

[0001] The present application relates to the field of low-voltage drawer cabinets, and in particular to an interlocking device for a low-voltage drawer cabinet. Background Art

[0002] The switch cabinet drawer compartment is an electrical device. Drawers of various sizes and models are arranged on the switch cabinet drawer compartment. Different circuit controllers are arranged in each drawer, so that the circuit is generally controlled through the switch cabinet drawer compartment. The drawer structure usually includes an inner drawer and a drawer base. Circuit elements are usually arranged in the inner drawer. The drawer base is provided with a switch to realize the conduction of the circuit elements in the inner drawer. There are three different special state positions between the inner drawer and the drawer base, namely, the separation position, the test position and the connection position. The separation position is the position where the circuit is completely disconnected. In this position, the drawer of the switch cabinet drawer compartment can be pulled out to operate the circuit in the drawer to effectively avoid causing danger. In the test position, the circuit of the equipment is partially connected and can be used as a test circuit, which is also called the test state. In this position, the drawer is not allowed to be pulled out. The full connection position means that in this position state, the circuit is in a state where it can be fully connected to work and can work normally after closing the switch, which is also called the connection position. In this state, the drawer is also not allowed to be pulled out. At the same time, these three special state positions are collectively referred to as working positions.

[0003] In the prior art, when the drawer cabinet needs to be inspected, the drawer cabinet needs to be opened, and the existing drawer cabinet is troublesome to open and close, thereby reducing the practicality.

[0004] An interlocking device for a low-voltage drawer cabinet which is convenient to open is now provided. Utility Model Content

[0005] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide an interlocking device for a low-voltage drawer cabinet, including: a cabinet body, which is provided with a cavity; a drawer cabinet, which is arranged in multiple numbers and is evenly slidably installed on the cavity, and a limit block is fixed on the drawer cabinet, and a limit groove corresponding to the limit block is arranged on the cabinet body; a mounting plate, which is fixed on the drawer cabinet; a rotating shaft, which is rotatably installed on the drawer cabinet and the mounting plate; a handle, which is fixed on the rotating shaft, and the handle is located on the outside; a disc, which is fixed on the other end of the rotating shaft; a fixed sleeve, which is arranged in two numbers and is symmetrically fixed at both ends of the drawer cabinet; a plug-in rod, which is slidably installed on the fixed sleeve; a connecting rod, which is arranged in two numbers and is hinged between the centrifugal ends of the connecting rod and the disc; a plug-in slot, which is opened on the cabinet body, and the plug-in rod passes through the drawer cabinet and is plugged into the plug-in slot.

[0007] When it is necessary to install the drawer cabinet, first align the limit block on the drawer cabinet with the limit slot. When the drawer cabinet cannot slide anymore, the rotating shaft is rotated under the action of the torsion spring, thereby the disc is rotated. At the same time, under the action of the connecting rod, the plug-in rod is squeezed and stably plugged into the plug-in slot, thereby fixing the drawer cabinet. Then the abutment block can be installed through the fixing bolt. The abutment block plays the role of a limit block. When it is necessary to open it, the handle can be turned to rotate the rotating shaft, thereby rotating the disc, and under the action of the connecting rod, the plug-in rod is disengaged from the plug-in slot, thereby the drawer cabinet can be slid for easy maintenance. When the drawer cabinet needs to be replaced, the fixing bolt can be turned to disengage the fixing bolt from the abutment block, thereby taking out the abutment block. At this time, the abutment block is no longer abutting the limit block, thereby the drawer cabinet can be taken out for maintenance.

[0008] Furthermore, an abutment block is detachably mounted on the end of the limiting groove, the abutment block is located on the end of the limiting groove, a fixing bolt is threadedly connected to the cabinet, and the fixing bolt is threadedly connected to the abutment block, and the abutment block is used to limit the limiting block.

[0009] Furthermore, a torsion spring is sleeved on the rotating shaft and fixedly connected between the disc and the cabinet, and the torsion spring is used for resetting the rotating shaft.

[0010] Furthermore, the two connecting rods are symmetrically arranged about the center of the disk.

[0011] Furthermore, there are two limit blocks on the two side panels of the drawer cabinet.

[0012] Furthermore, the number of the fixing bolts is two, and the two fixing bolts are symmetrically arranged.

[0013] Furthermore, the handle is provided with anti-slip patterns.

[0014] Furthermore, the number of the limiting grooves is two, and the limiting grooves correspond to the limiting blocks.

[0015] Furthermore, support blocks are fixedly connected at the dead corners of the bottom of the cabinet.

[0016] The beneficial effect of the present application is that an interlocking device for a low-voltage drawer cabinet that is easy to open is provided. BRIEF DESCRIPTION OF THE DRAWINGS
