Description

Technical Field

[0001] The utility model relates to the field of low-voltage switch cabinets, and more particularly to a low-voltage switch cabinet with adjustable internal volume. Background Art

[0002] As the name suggests, low-voltage switchgear is a device that connects low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers and then transferred to low-voltage cabinets. The low-voltage cabinets are then transferred to distribution boxes for various power users. Inside, there are nothing more than some protective devices such as switches and circuit breakers assembled into one electrical equipment. The interior of the low-voltage switchgear is usually separated by partitions to facilitate the installation of electronic components.

[0003] Some existing low-voltage switchgear cabinets have internal partitions that cannot be adjusted, and components are installed inside the main body of the equipment, making it impossible to adjust the position according to the size of the components. This sometimes results in insufficient space or excessive space, reducing the utilization rate of the internal space of the low-voltage switchgear. Therefore, to solve this problem, we propose a low-voltage switchgear with adjustable internal volume. Utility Model Content

[0004] In order to solve the above problems, the present invention provides a low-voltage switchgear with adjustable internal volume, which adopts the following technical solutions:

[0005] A low-voltage switchgear with adjustable internal volume comprises a cabinet body, a cabinet door hinged on one side of the cabinet body, columns are provided at the four corners of the bottom end of the cabinet body, a mounting frame is fixedly installed on the top of the cabinet body, the bottom end of the mounting frame extends into the cabinet body, the inner wall of the cabinet body is provided with multiple groups of support blocks distributed in a linear array, there are two support blocks in the same group and they are symmetrically distributed in the cabinet body, a placement plate is slidably installed between the two support blocks in the same group, sliders are fixedly installed on both sides of the placement plate, and slide grooves matching the sliders in the same group are provided on the opposite sides of the two support blocks in the same group, movable grooves are provided on the tops of the slide grooves, positioning components are provided in the movable grooves, clamping components are provided on the tops of the placement plates, air inlets distributed in a rectangular array are provided on the top of the mounting frame, multiple air outlets distributed in a linear array are provided on both sides of the lower section of the cabinet body, and a wind blowing component is provided in the mounting frame.

[0006] By adopting the above technical solution, when the equipment is used, the staff places the cabinet in a suitable position, and then places the placement plate in the cabinet, so that the sliders installed on both sides of the cabinet are placed in the slide grooves opened on the side walls of the support blocks. The placement plate is initially fixed by the engagement of the sliders and the slide grooves, and a positioning component is provided in the slide groove to position and stabilize the slider, which is beneficial to maintaining the stability of the placement of the placement plate. By setting multiple groups of support blocks, it is convenient for the staff to adjust the placement position of the placement plate, and then it can play a role in adjusting the distance between two adjacent placement plates, which is convenient for the staff to install electronic components of different sizes, which is beneficial to improve the utilization rate of the internal structure of the cabinet. The top of the placement plate plays a role in clamping and stabilizing the electronic components through the setting of the clamping component, which is beneficial to reducing the damage to the electronic components caused by vibration when the cabinet is moved. The wind blowing component is set in the installation frame to generate wind force, which is introduced into the cabinet, and the heat inside the cabinet is discharged through the air outlet, which can play a role in heat dissipation.

[0007] Furthermore, the positioning assembly includes a positioning rod slidably installed in the movable groove, a second spring is connected between the top of the positioning rod and the inner wall of the top of the movable groove in the same group, and a positioning groove matching the positioning rod in the same group is provided at the top of the slider.

[0008] By adopting the above technical solution, when the slider slides into the sliding groove, the slider pushes the positioning rod to slide into the movable groove, and the positioning rod pushes the second spring of the same group to contract. When the slider is engaged with the sliding groove of the same group, the positioning rod returns to its original position under the elastic force of the second spring of the same group, and the end of the positioning rod is engaged with the positioning groove opened at the top of the slider of the same group, which can play the role of positioning and stabilizing the slider, and then further fix the placement plate, which is conducive to maintaining the stability of the placement of the placement plate.

[0009] Furthermore, two symmetrically distributed limiting blocks are fixedly mounted on the side walls of the top ends of the positioning rods, and limiting grooves matching the limiting blocks of the same group are formed on the inner walls of the movable grooves.

[0010] By adopting the above technical solution, when the positioning rod slides in the movable groove, the positioning rod slides in the same group of limiting grooves with the limiting block. The cooperation between the limiting block and the limiting groove is conducive to maintaining the sliding stability of the positioning rod and helps to prevent the positioning rod from leaving the movable groove.

[0011] Furthermore, the clamping assembly includes two mounting plates fixedly mounted on the top of the placement plates, the two mounting plates are symmetrically distributed at the top of the placement plates in the same group, two symmetrically distributed clamping plates are slidably mounted between the two mounting plates, and a plurality of first springs distributed in a linear array are fixedly connected between the clamping plates and the opposite side of the mounting plates in the same group.

[0012] By adopting the above technical solution, the staff installs the electronic components on the top of the placement plate. The clamp contacts the opposite side of the electronic component under the elastic force of the first spring in the same group. Through the cooperation of the clamp and the first spring, the electronic components are clamped and stabilized.

[0013] Furthermore, two symmetrically distributed balancing blocks are fixedly installed on the bottom end of the splint, and a balancing groove matching the balancing blocks in the same group is provided on the top of the placement plate. Stabilizing blocks are fixedly installed on the opposite sides of the two mounting plates in the same group, and a stabilizing groove matching the stabilizing blocks on the same side is provided on the opposite sides of the two support blocks in the same group.

[0014] By adopting the above technical solution, when the splint slides on the placement plate under the elastic force of the first spring, the splint slides with the balancing block, and the balancing block slides in the same group of balancing grooves. The cooperation of the balancing block and the balancing groove is conducive to maintaining the stability of the sliding of the splint. When the placement plate is installed, the placement plate slides synchronously with the installation plate, and the stabilizing block installed on the side wall of the installation plate slides in the stabilizing groove opened on the side wall of the support block. The engagement of the stabilizing block and the stabilizing groove plays a role in supporting and stabilizing the installation plate, and then plays a role in balancing and stabilizing the placement plate, which is conducive to maintaining the stability of the installation of the placement plate.

[0015] Furthermore, two symmetrically distributed plug-in blocks are fixedly installed on the side of the placement plate away from the cabinet door, and slots matching the plug-in blocks are opened on the inner wall of the cabinet body away from the cabinet door. Two symmetrically distributed stop blocks are fixedly installed on the opposite sides of the two support blocks in the same group, and the stop blocks in the same group are all located below the placement plates in the same group.

[0016] By adopting the above technical solution, the end of the placement board is provided with an insert block, and the insert block is engaged with the slot opened inside the cabinet, which plays a role in positioning and stabilizing the placement board, and can also play a role in stabilizing the placement board. The side wall of the support block is provided with a stop block, and the stop block is located below the placement board, and the top of the stop block contacts the bottom end of the placement board, which can play a role in supporting and stabilizing the placement board, which is conducive to maintaining the stability of the placement of the placement board.
