Abstract
Description
Technical Field
[0001] This utility model relates to the field of switch cabinet technology, specifically a modular switch cabinet. Background Technology
[0002] A switchgear is a type of electrical equipment. External power lines first enter the main control switch inside the cabinet, and then enter the branch control switches. Each branch circuit is configured according to its needs. Examples include instruments, automatic control systems, motor magnetic switches, various AC contactors, etc. Some switchgear also have high-voltage and low-voltage compartments and are equipped with high-voltage busbars, such as those in power plants.
[0003] According to announcement number CN 220086671 U, a modular switchgear is disclosed, relating to the field of switchgear technology. The switchgear includes a cabinet door, with a switchgear body at one end of the cabinet door. The switchgear body is equipped with a combination device, which includes: a free assembly component, a splicing device, and an assembly slot. The assembly slot is located on the front side of the upper end of the switchgear body.
[0004] This device features freely assembling components. During installation of the upper dustproof plate, assembly and reinforcement bolts are used to pass through both ends of the upper dustproof plate and the top of the switchgear body. These freely assembling components allow for easy adjustment and allocation, avoiding the increased difficulty of equipment placement caused by fixed-size spaces. When internal equipment needs to be replaced later, different equipment models and sizes require different placement spaces; the freely assembling components provide reconfiguration space, reducing the cost of switchgear replacement and modification. However, the support plate position is not adjustable, which makes the switchgear less adaptable to the installation requirements of different specifications and quantities of electrical components.

[0007] The combined mechanism includes a bidirectional lead screw, which is rotatably connected to the bottom of the inner wall of the cabinet near the left side. A crank is fixedly connected to the top of the bidirectional lead screw. Moving blocks are symmetrically threaded onto the surface of the bidirectional lead screw. Limiting rods are symmetrically fixedly connected to the upper and lower sides of the inner wall of the cabinet near the left side. Fixed rods are symmetrically fixedly connected to the upper and lower sides of the inner wall of the cabinet near the front right side. Slider blocks are symmetrically slidably connected to the surfaces of the two fixed rods. Connecting frames are fixedly connected to the back of the two moving blocks. A U-shaped frame is fixedly connected to the side of the two moving blocks and the two sliders away from the inner wall of the cabinet. A partition is slidably connected to the U-shaped frame.
[0008] Preferably, the bottom of the cabinet has a hole near the left side that matches the bidirectional lead screw, and the surface of the bidirectional lead screw passes through and is rotatably connected to the hole.
[0009] Preferably, the top of the movable block has a hole that matches the limiting rod, and the movable block is slidably connected to the surface of the limiting rod through the hole. The limiting rod limits the two movable blocks, so that the two movable blocks move up and down with the rotation of the bidirectional lead screw.
[0010] Preferably, the other end of the connecting frame is fixedly connected to the back of the slider, and the connecting frame enables the slider to move synchronously with the movement.
[0011] Preferably, the fixing mechanism includes an L-plate, which is fixedly connected to the top of the U-shaped frame near the front. An insert block is provided on the top of the L-plate, and a pull plate is fixedly connected to the top of the insert block. A first fixing plate is fixedly connected to the front of the inner wall of the L-plate. A guide rod is provided at the bottom of the first fixing plate near the back. A limit ring is fixedly connected to the surface of the guide rod near the top. A second fixing plate is fixedly connected to the back of the insert block near the bottom. A spring is sleeved between the first and second fixing plates on the surface of the guide rod. Slots corresponding to the insert block are opened on the left and right sides of the bottom of the partition plate near the front.
[0012] Preferably, the top of the L-plate and the top of the first fixing plate are provided with grooves that match the insert block, and the surface of the insert block is slidably connected to the grooves.

[0014] Compared with the prior art, this utility model provides a combined switch cabinet, which has the following advantages:
[0015] This modular switchgear features a combined mechanism with a bidirectional lead screw and crank. Operators simply turn the crank to drive the bidirectional lead screw, moving the moving block up and down, which in turn moves the slider, connecting frame, and U-shaped frame along the cabinet. This structure reduces manual operation difficulty and improves the efficiency of partition installation and adjustment. Simultaneously, the up-and-down movement of the moving block allows for quick and flexible partitioning of the cabinet's internal space, meeting the installation requirements of electrical components of different sizes and enabling the switchgear to adapt to diverse power system configurations. Furthermore, the inclusion of limit rods and fixing rods ensures the stability of the moving block and slider during movement, preventing installation errors caused by shaking and further enhancing operational convenience and reliability.
[0016] In this modular switchgear, the spring mechanism in the fixing system allows the plug to automatically engage with the slot of the partition, forming a secure mechanical lock. This effectively prevents the partition from shifting due to vibration or external forces during use, ensuring the stability of the switchgear's internal structure. Simultaneously, the connection design between the pull plate and the plug allows operators to easily lift the pull plate, overcoming the spring force to remove the plug from the slot. This facilitates the disassembly and reinstallation of the partition, balancing secure fixing with ease of operation. Furthermore, the beveled shape at the bottom of the plug automatically guides it into the slot during partition installation, eliminating the need for precise alignment and further simplifying the installation process and improving efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0027] This utility model provides the following technical solution: Example 1
[0028] Please see Figure 1-4 This utility model provides a technical solution: a combined switch cabinet, including a base 1, a cabinet body 2 fixedly connected to the bottom of the base 1, a cabinet door 3 hinged to the left side of the front of the cabinet body 2, a combination mechanism 4 provided on the inner wall of the cabinet body 2, and a fixing mechanism 5 provided inside the combination mechanism 4.
[0029] The combined mechanism 4 includes a two-way lead screw 41, which is rotatably connected to the bottom of the inner wall of the cabinet 2 near the left side. A crank 42 is fixedly connected to the top of the two-way lead screw 41. Moving blocks 43 are symmetrically threaded on the surface of the two-way lead screw 41. Limiting rods 44 are symmetrically fixedly connected to the inner wall of the cabinet 2 near the left side. Fixing rods 45 are symmetrically fixedly connected to the upper and lower sides of the inner wall of the cabinet 2 near the front right side. Sliding blocks 46 are symmetrically slidably connected to the surfaces of the two fixing rods 45. Connecting frames 47 are fixedly connected to the back of the two moving blocks 43. A U-shaped frame 48 is fixedly connected to the side of the two moving blocks 43 and the two sliding blocks 46 away from the inner wall of the cabinet 2. A partition 49 is slidably connected to the inside of the U-shaped frame 48.
[0030] The bottom of the cabinet 2 is provided with a hole near the left side that matches the bidirectional lead screw 41, and the surface of the bidirectional lead screw 41 passes through and is rotatably connected to the hole.
[0031] The top of the movable block 43 has a hole that matches the limiting rod 44, and the movable block 43 is slidably connected to the surface of the limiting rod 44 through the hole. The limiting rod 44 limits the two movable blocks 43, so that the two movable blocks 43 move up and down with the rotation of the bidirectional lead screw 41.
[0032] The other end of the connecting bracket 47 is fixedly connected to the back of the slider 46, and the connecting bracket 47 makes the slider 46 move synchronously with the movement. Example 2
[0033] Please see Figure 5-6 Furthermore, based on Embodiment 1, a fixing mechanism 5 is obtained.
[0034] The fixing mechanism 5 includes an L-plate 51, which is fixedly connected to the top of the U-shaped frame 48 near the front. An insert block 52 is provided on the top of the L-plate 51, and a pull plate 53 is fixedly connected to the top of the insert block 52. A first fixing plate 54 is fixedly connected to the front of the inner wall of the L-plate 51. A guide rod 55 is provided at the bottom of the first fixing plate 54 near the back. A limit ring 56 is fixedly connected to the surface of the guide rod 55 near the top. A second fixing plate 57 is fixedly connected to the back of the insert block 52 near the bottom. A spring 58 is sleeved between the first fixing plate 54 and the second fixing plate 57 on the surface of the guide rod 55. Slots 59 corresponding to the insert block 52 are opened on the left and right sides of the bottom of the partition plate 49 near the front.
[0035] The top of L-plate 51 and the top of the first fixing plate 54 are provided with grooves that match the insert block 52. The surface of the insert block 52 passes through and slides up and down in the groove. The first fixing plate 54 supports the insert block 52 so that the insert block 52 can move up and down stably. The top of the first fixing plate 54 near the back is provided with a hole that matches the guide rod 55. The surface of the guide rod 55 passes through and slides up and down in the hole.
[0036] The top end of the spring 58 is fixedly connected to the bottom of the first fixing plate 54, and the bottom end of the spring 58 is fixedly connected to the top of the second fixing plate 57. The bottom end of the insert block 52 is sloping.
[0037] In actual operation, when this device is used and the height of the partition 49 within the cabinet 2 needs to be adjusted, the operator turns the crank handle 42. The crank handle 42 drives the bidirectional lead screw 41 to rotate within a hole on the bottom of the inner wall of the cabinet 2, near the left side. Since the bidirectional lead screw 41 has symmetrically threaded moving blocks 43 connected to its surface, and the top of each moving block 43 has a hole matching the limiting rod 44, which limits the moving blocks 43, as the bidirectional lead screw 41 rotates, the two moving blocks 43 move up and down along the surface of the limiting rod 44. Simultaneously, the connecting bracket 47 fixedly connected to the back of the two moving blocks 43 drives the slider 46 to slide synchronously on the surface of the fixed rod 45, thereby causing the U-shaped frame 48, which is fixedly connected to the moving blocks 43 and the slider 46, to move up and down. Because the partition 49 is slidably connected within the U-shaped frame 48, the up and down movement of the U-shaped frame 48 can drive the partition 49 to move up and down within the cabinet 2, achieving flexible adjustment of the partition 49's height.
[0038] Once the partition 49 is moved to the appropriate position, it needs to be secured. At this point, the securing mechanism 5 comes into play. Since the top of the spring 58 is fixedly connected to the bottom of the first fixing plate 54, and the bottom is fixedly connected to the top of the second fixing plate 57, in its natural state, the spring 58 is compressed, pushing the insert block 52 downwards. This causes the insert block 52 to insert into the slots 59 on the left and right sides of the bottom of the partition 49, near the front, thus securing the partition 49 firmly within the U-shaped frame 48. When it is necessary to disassemble or readjust the position of the partition 49, pull the pull plate 53 upwards. The pull plate 53 moves the insert block 52 upwards, compressing the spring 58 and removing it from the slot 59. At this point, the partition 49 can be slid back and forth to remove it from the U-shaped frame 48, or after adjusting it to another position, release the pull plate 53. Under the elastic force of the spring 58, the insert block 52 re-inserts into the slot 59 in the new position, thus re-secured the partition 49.
[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
