Description

Technical Field

[0001] This utility model relates to the field of motor cabinet technology, specifically to a modular quick-release power cabinet. Background Technology

[0002] A power distribution cabinet is the final stage equipment in a power distribution system. A power distribution cabinet is a general term for a motor control center. Power distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy from a circuit of the upstream power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] Existing power cabinets, in order to facilitate disassembly and assembly, often employ modular designs for their mounting frames and plates, pre-connected via corresponding connection structures, and then further secured with bolts. However, this bolt-fixing method is cumbersome due to the large number of bolts, resulting in low efficiency. Furthermore, bolts located in cabinet corners or inside the cabinet can obstruct operator movement, further hindering efficiency. Therefore, a modular, quick-release power cabinet is urgently needed to address these issues. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a modular quick-release power cabinet, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a modular quick-release power cabinet, including a cabinet body. Two sets of connecting components are symmetrically installed on the two side walls of the cabinet body. Each connecting component includes a T-shaped connecting groove opened on the inner wall of the cabinet body. A support frame is installed in the connecting groove. A drive component is installed above the support frame. The drive component includes a transmission box fixed on the inner wall of the cabinet body. A transmission shaft is installed in the transmission box. A main gear is sleeved on the transmission shaft. A secondary gear is connected to one side of the main gear. A locking component is provided on the secondary gear. The locking component includes a screw rod located at the middle of the bottom end of the secondary gear. Three sets of screw blocks are arranged in an array on the screw rod. An L-shaped locking block is fixed on one side wall of the screw block. An L-shaped locking cavity is opened on the back wall of the support frame at a position corresponding to the locking block.

[0008] By adopting the above technical solution, when disassembling the support frame, the drive assembly first drives the screw in the locking assembly to rotate, and then the screw block moves the locking block downward under the action of the thread, so that it separates from the locking cavity. Then, the connecting assembly separates the support frame from the connecting cavity, thus realizing the disassembly of the support frame.

[0009] Furthermore, the connecting assembly also includes a T-shaped connecting block fixed to the side wall of the support frame, the connecting block being inserted into the connecting groove.

[0010] By adopting the above technical solution, the connection groove and the connection block can be combined to realize the initial connection of the support frame, and at the same time, it is easy to disassemble it.

[0011] Furthermore, the drive assembly also includes a knob fixed to one end of the transmission shaft. The knob is located on the outside of the transmission box. The main gear is fixed on the transmission shaft. The main gear meshes with the secondary gear. Both the main gear and the secondary gear are bevel gears.

[0012] By adopting the above technical solution, the knob can drive the transmission shaft to rotate, and the transmission shaft then drives the auxiliary gear to rotate through the main gear.

[0013] Furthermore, the top end of the screw is fixedly connected to the middle of the bottom end of the auxiliary gear, the bottom end of the screw is rotatably connected to the bottom wall of the cabinet, the screw block is threadedly connected to the screw, and the screw block is slidably connected to the side wall of the cabinet.

[0014] By adopting the above technical solution, the secondary gear drives the screw to rotate, thereby causing the screw block to move the locking block.

[0015] Furthermore, the locking cavity is formed on the support frame, the locking block is inserted into the locking cavity, and the locking block is fixed to one side wall of the screw block by screws.

[0016] By adopting the above technical solution, the locking block combined with the locking cavity can further lock and fix the support frame, while also facilitating the release of the fixation.

[0017] Furthermore, the side wall of the support frame has multiple sets of positioning holes arranged in an array in the middle. An installation plate is installed between the positioning holes. A positioning component is provided on one side of the upper end of the installation plate. The positioning component includes a sliding groove on the installation plate. An elastic telescopic rod is installed in the sliding groove. The elastic telescopic rod has a built-in spring. A lever is fixed on the movable part of the elastic telescopic rod. A linkage rod is fixed on one side wall of the lever. A positioning block is fixed at one end of the linkage rod. The linkage rod passes through the installation plate. A positioning block is also fixed at the other end of the installation plate. The positioning block is inserted into the positioning hole.

[0018] By adopting the above technical solution, in the use state, both sets of positioning blocks are in the positioning holes, which can fix the mounting plate. When disassembly is required, the elastic telescopic rod can be compressed by the lever, thereby causing the linkage rod to move a set of positioning blocks and separate them from the positioning holes, so that one end of the mounting plate can be released from fixation. Then, the other end of the mounting plate can be separated from the support frame to achieve the disassembly of the mounting plate.

[0019] Furthermore, the mounting plate has multiple sets of mounting holes arranged in an array, and a cabinet door is installed on one side wall of the cabinet via hinges.

[0020] By adopting the above technical solution, the mounting holes on the mounting plate facilitate the fixing of electrical components, and the cabinet door can seal the cabinet body.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] This utility model, through the matching use of a drive component and a locking component, allows for easy disassembly of the support frame. Simply rotate the drive shaft via a knob, which in turn drives the screw on the secondary gear via the main gear. This causes the screw block to move downwards under the action of the threads, separating it from the locking cavity. Then, the connecting component separates the support frame from the connecting cavity, thus achieving disassembly of the support frame and facilitating its installation. By using this mechanism instead of the original bolt fixing, the disassembly efficiency of components inside the power cabinet is effectively improved, and the operation is simple and the performance is high.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] like Figures 2-6As shown, a modular quick-release power cabinet in this embodiment includes a cabinet body 1. Two sets of connecting components 3 are symmetrically installed on the two inner side walls of the cabinet body 1. The connecting components 3 include a T-shaped connecting groove 301 opened on the inner wall of the cabinet body 1. A support frame 303 is installed in the connecting groove 301. A drive component 4 is installed above the support frame 303. The drive component 4 includes a transmission box 401 fixed to the inner wall of the cabinet body 1. A transmission shaft 403 is installed in the transmission box 401. A main gear 404 is sleeved on the transmission shaft 403. A secondary gear 405 is connected to one side of the main gear 404. A locking component 5 is provided on the secondary gear 405. The locking component 5 includes a locking mechanism. The screw 501 at the bottom center of the auxiliary gear 405 has three sets of screw blocks 502 arranged in an array on the screw 501. An L-shaped locking block 503 is fixed on one side wall of the screw block 502. An L-shaped locking cavity 504 is opened on the back wall of the support frame 303 at a position corresponding to the locking block 503. When disassembling the support frame 303, the screw 501 in the locking assembly 5 is first rotated by the drive assembly 4. Then, the screw block 502 moves the locking block 503 down under the action of the thread, so that it separates from the locking cavity 504. Then, the support frame 303 is separated from the connecting cavity by the connecting assembly 3, so that the support frame 303 can be disassembled.

[0036] like Figures 2-6As shown, in this embodiment, the connecting assembly 3 further includes a T-shaped connecting block 302 fixed to the side wall of the support frame 303. The connecting block 302 is inserted into the connecting groove 301. The driving assembly 4 further includes a knob 402 fixed to one end of the transmission shaft 403. The knob 402 is located on the outside of the transmission box 401. The main gear 404 is fixed to the transmission shaft 403. The main gear 404 meshes with the secondary gear 405. Both the main gear 404 and the secondary gear 405 are bevel gears. The top end of the screw 501 is fixedly connected to the middle of the bottom end of the secondary gear 405. The bottom end of the screw 501 is rotatably connected to the bottom wall of the cabinet 1. The screw block 502 is threadedly connected to the screw 501. The screw block 502 is slidably connected to the side wall of the cabinet 1. The locking cavity 504 is formed on the support frame 303. The locking block 503 is inserted into the locking cavity 504. The locking block 503 is fixed to one side wall of the screw block 502 by screws. During the use of the cabinet, the locking block 503 is located in the locking cavity 504 to lock and fix the bearing component. When it is necessary to disassemble the bearing frame 303, simply rotate the drive shaft 403 by turning the knob 402. The drive shaft 403 then drives the screw 501 on the auxiliary gear 405 to rotate through the main gear 404. This causes the screw block 502 to move the locking block 503 down under the action of the thread, separating it from the locking cavity 504. Then, the bearing frame 303 is separated from the connecting cavity by the connecting component 3, thus releasing the fixation of the bearing frame 303. Then, the bearing frame 303 is separated from the cabinet body 1 by the action of the connecting groove 301 and the connecting block 302, thus realizing the disassembly of the bearing frame 303. It also facilitates its installation. By using the above mechanism to replace the original bolt fixing, the disassembly efficiency of the components in the power cabinet can be effectively improved. Moreover, the operation process is simple and the performance is high.

[0037] like Figure 1 , Figure 2 , Figure 7 as well as Figure 8As shown, in this embodiment, multiple sets of positioning holes 7 are arrayed in the middle of the side wall of the support frame 303. A mounting plate 6 is installed between the positioning holes 7. A positioning component 8 is provided on one side of the upper end of the mounting plate 6. The positioning component 8 includes a sliding groove 801 on the mounting plate 6. An elastic telescopic rod 802 is installed in the sliding groove 801. The elastic telescopic rod 802 has a built-in spring. A lever 803 is fixed to the movable part of the elastic telescopic rod 802. A linkage rod 804 is fixed to one side wall of the lever 803. A positioning block 805 is fixed to one end of the linkage rod 804. The linkage rod 804 passes through the mounting plate 6, and the other end of the mounting plate 6 is also fixed... A positioning block 805 is fixed and inserted into the positioning hole 7. Multiple sets of mounting holes are arrayed on the mounting plate 6. A cabinet door 2 is installed on one side wall of the cabinet 1 via a hinge. In use, both sets of positioning blocks 805 are in the positioning hole 7, which can fix the mounting plate 6. When disassembly is required, the elastic telescopic rod 802 can be compressed by the lever 803, which will cause the linkage rod 804 to move a set of positioning blocks 805 and separate them from the positioning hole 7, so that one end of the mounting plate 6 can be released from fixation. Then, the other end of the mounting plate 6 can be separated from the support frame 303 to achieve the disassembly of the mounting plate 6.

[0038] The specific implementation process of this embodiment is as follows: First, during the use of the power cabinet, both sets of positioning blocks 805 are in the positioning holes 7 to fix the mounting plate 6. The locking block 503 is located in the locking cavity 504 to lock and fix the bearing component. When it is necessary to disassemble the components of the cabinet 1, the electrical components are first separated from the mounting plate 6. The elastic telescopic rod 802 is compressed by the lever 803, which causes the linkage rod 804 to drive a set of positioning blocks 805 to move and separate from the positioning holes 7, so that one end of the mounting plate 6 can be released. Then, the other end of the mounting plate 6 is separated from the bearing frame 303 to disassemble the mounting plate 6. Then, the drive shaft 403 is rotated by the knob 402. The drive shaft 403 then drives the screw 501 on the auxiliary gear 405 to rotate through the main gear 404, which in turn causes the screw block 502 to move the locking block 503 downward under the action of the thread, separating it from the locking cavity 504. Then, the connecting assembly 3 separates the support frame 303 from the connecting cavity, thus releasing the fixation of the support frame 303. Then, under the action of the connecting groove 301 and the connecting block 302, the support frame 303 is separated from the cabinet 1, thus realizing the disassembly of the support frame 303. Repeating the above operation also facilitates the installation of parts. By using the above mechanism to replace the original bolt fixing, the disassembly efficiency of the parts in the power cabinet can be effectively improved, and the operation process is simple and the performance is high.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
