Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, in particular to a distribution cabinet drawer. Background Art

[0002] The power distribution cabinet is now widely used in the power distribution system of power users such as substations, power plants, factories and mines, and is mainly used for power conversion, distribution and control of power, lighting and power distribution equipment. The power distribution cabinet includes a cabinet shell with heat dissipation holes and a load-bearing partition for dividing the cabinet shell into multiple power distribution chambers. In order to facilitate the inspection and maintenance of components in the power distribution chamber, the power distribution cabinet of the prior art also includes multiple power distribution drawers for placing components. The power distribution drawer consists of a pull-out panel with a handle, three side panels and a bottom plate. The power distribution drawer is slidably fitted on the load-bearing partition. When inspection and maintenance are required, the power distribution drawer can be pulled out. However, during long-term use, it is necessary to ensure the assembly stability between the power distribution drawer and the cabinet, so that the drawer and the cabinet can still be stably matched even after long-term use. On the other hand, the plug-in slots for plug-in lines between the drawer and the cabinet need to be able to be stably matched to avoid damage to the lines during the movement of the drawer. Therefore, a power distribution cabinet drawer is needed. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a power distribution cabinet drawer, which is used to solve the problem of assembly stability between the drawer and the power distribution cabinet in the prior art.

[0004] To achieve the above objectives and other related objectives, the present invention provides the following technical solutions:

[0005] A power distribution cabinet drawer comprises a drawer shell and a base, wherein the drawer shell is slidably connected to the base, a chassis is provided between the bottom of the drawer shell and the base, pulleys are symmetrically connected to the inside of the two side walls of the drawer shell and can be rotated along the sliding direction of the drawer, pulley notches are provided on the chassis and below the pulley, the bottom of the pulley is slidably fitted with the base, shell limit plates extending upward are provided on both sides of the base, a plug-in plate is provided at the rear end of the base, and a plug-in groove is provided on the plug-in plate.

[0006] To implement the above technical solution, the stability and reliability of the sliding fit between the drawer shell and the base can be ensured by setting a pulley, and the shell limit plates extending upward are provided on both sides of the base, which can limit the displacement of the drawer shell in the directions of both sides and avoid loosening and overturning of the drawer shell during sliding. By providing a pulley notch on the chassis and below the pulley, the sliding fit between the bottom of the pulley and the base can be achieved, which can ensure the stability and reliability of the pulley and make the movement of the drawer shell more stable and reliable. The provision of the plug-in board can facilitate the assembly of the external circuit, and the plug-in groove is provided on the plug-in board, which can provide positioning for the assembly of the external circuit, thereby ensuring the assembly stability and reliability of the circuit.

[0007] In one embodiment of the present invention, a pulley skirt is provided on the outer side of the two side walls of the drawer shell, and a baffle extending toward one side of the drawer shell is provided on the top of the shell limit plate, and the pulley skirt and the baffle are slidably matched.

[0008] To implement the above technical solution, by setting a pulley skirt and a baffle, it is possible to ensure that the vertical displacement of the drawer shell is limited during use, avoiding the drawer shell from shaking up and down, thereby ensuring the assembly stability and safety of the external circuit in the plug-in slot.

[0009] In one embodiment of the present invention, four groups of pulleys are symmetrically arranged at the bottom of the drawer shell, and guide plates inclined downward are arranged at both ends of the pulley skirt and above the pulley.

[0010] By implementing the above technical solution, the four sets of pulleys can make the operation of the drawer shell more stable and smooth, and the setting of the guide plate can cooperate with the baffle plate to make the sliding of the drawer shell on the base smoother and more stable.

[0011] In one embodiment of the present invention, a handle is provided on the outer end surface of the front baffle of the drawer shell. The handle is vertically arranged, and two groups of the handles are symmetrically arranged on the front baffle of the drawer shell.

[0012] To implement the above technical solution, by arranging the handles vertically, it is possible to facilitate manual pulling and drawing of the drawer shell, while also providing a more sufficient usable area on the front end surface of the drawer shell. The two sets of handles can ensure the smoothness and convenience of the pulling and drawing action.

[0013] In one embodiment of the present invention, a protective plate extending toward the rear end of the drawer shell is provided at the top inner side of the front baffle of the drawer shell.

[0014] By implementing the above technical solution, the provision of the protective plate can improve the safety of the use of the drawer shell, and prevent external debris from entering the drawer shell through the open upper end surface of the drawer shell when the drawer shell is in working condition, thereby affecting the normal use of the drawer shell. At the same time, it can also prevent manual contact with the exposed circuits inside the drawer shell from the open upper end surface of the drawer shell during maintenance, thereby ensuring safety of use.

[0015] In one embodiment of the present invention, a display screen is provided on the front baffle of the drawer shell.

[0016] By implementing the above technical solution, the setting of the display screen can facilitate the monitoring of the working environment inside the drawer shell.

[0017] In one embodiment of the present invention, a rear baffle is provided at the rear end of the drawer shell, and a rear plugging groove is provided on the rear baffle, and the position of the rear plugging groove matches the plugging groove.

[0018] By implementing the above technical solution, the arrangement of the rear baffle can improve the use stability of the drawer shell, and the rear plug-in slot on the rear baffle cooperates with the plug-in slot to achieve convenience and reliability in the installation of the line.

[0019] As described above, a power distribution cabinet drawer of the present invention has the following beneficial effects: by arranging a pulley, the stability and reliability of the sliding fit between the drawer shell and the base can be ensured, and the base is provided with shell limit plates extending upward on both sides, which can limit the displacement of the drawer shell in the directions of both sides, thereby avoiding loosening and overrunning of the drawer shell during sliding. By arranging a pulley notch on the chassis and below the pulley, the sliding fit between the bottom of the pulley and the base can be achieved, which can ensure the stability and reliability of the pulley and make the movement of the drawer shell more stable and reliable. The arrangement of the plug board can facilitate the assembly of the external circuit, and the plug board is provided with a plug groove, which can provide a positioning effect for the assembly of the external circuit, thereby ensuring the assembly stability and reliability of the circuit.
