Abstract
Description
Technical Field
[0001] This utility model relates to the field of power distribution cabinet technology, specifically to a switch installation structure for a power distribution cabinet. Background Technology
[0002] The distribution cabinet is a new type of distribution cabinet designed according to the requirements of the Ministry of Energy, the majority of power users and design departments, and in accordance with the principles of safety, economy, rationality and reliability. The product has high breaking capacity, good dynamic and thermal stability and flexible electrical scheme. In the distribution cabinet, the switch needs to be fixedly installed in the distribution cabinet through the limit installation mechanism.
[0003] A power distribution cabinet switch installation structure, disclosed in publication CN 222422866 U, includes a mounting plate within the cabinet cavity and a locking block fixedly mounted on the rear side of the switch. The cabinet cavity has two symmetrical mounting plates fixedly connected to it. The mounting plate is fixedly connected to the front of the mounting plates, and screws are threaded through the front of the mounting plates. By lifting the switch, the locking block enters the mounting groove cavity, causing rack two to engage with rack one, thus fixing the locking block in the mounting plate cavity. Positioning grooves and positioning blocks further position the locking block, allowing a limiting arc block to enter the limiting arc groove cavity, thus fixing the switch to the mounting plate. When the switch is damaged and needs disassembly, the switch is held by hand, unlocking the engagement of rack two and rack one, allowing the locking block on the rear side of the switch to disengage from the mounting groove cavity. This allows for quick switch installation and independent replacement when damaged, improving the efficiency of power distribution cabinet switch maintenance.
[0004] However, the above structure still has some shortcomings in use. It relies on the meshing of the rack and pinion to achieve fixation. After long-term use, the rack and pinion are prone to wear and loosening, which affects the reliability of fixation. There is no special structure designed for the management of wires after the switch is wired. Multi-circuit wires are easy to get tangled and messy, which increases the difficulty of later maintenance. During installation, the rack and pinion meshing position needs to be accurately aligned, which requires a high level of operator proficiency and limits efficiency when installing in batches. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a switch installation structure for a power distribution cabinet. It solves the problems of relying on rack and pinion engagement for fixation, which can lead to loosening of the engagement due to wear after long-term use, affecting the reliability of the fixation; the lack of a dedicated structure for managing wires after switch wiring, which can cause multi-circuit wires to become tangled and messy, increasing the difficulty of later maintenance; and the need for precise alignment of the rack and pinion engagement position during installation, which requires a high level of operational skill and limits efficiency during batch installation.
[0006] This utility model provides the following technical solution: a switch installation structure for a power distribution cabinet, including a mounting plate and an air switch. A mounting block is installed on the upper surface of the mounting plate. A slider is fixedly installed on the top and bottom walls of the groove on the back of the air switch. A sliding groove is opened on the upper and lower surfaces of the mounting block. The two sliders can slide inside the two sliding grooves respectively. A horizontal plate is fixedly connected to the surface of the mounting plate. A row of grooves is formed on the surface of the horizontal plate. A row of limiting plates is rotatably installed on the surface of the horizontal plate, and the limiting plates correspond to the grooves.
[0007] Preferred technical solution 1: The upper and lower surfaces of the mounting block are fixedly connected to connecting plates, and the upper and lower surfaces of the air switch are fixedly installed with short plates. The surfaces of the short plates and the connecting plates are provided with matching screw holes.
[0008] Preferred technical solution 2: Each of the limiting plates has a set of movable grooves on its surface, and each movable groove has a locking rod slidably fitted inside it. The surface of the horizontal plate has multiple sets of locking grooves that match the locking rods, and a spring is fitted on one side of each locking rod.
[0009] Preferred technical solution 3: A pull plate is fixedly connected to one end of the outer side of each group of clamp rods.
[0010] Preferred technical solution four: Each of the limiting plates has an iron block embedded in its surface, and the horizontal plate has a row of magnets embedded in its surface.
[0011] Preferred technical solution five: Each of the wire grooves is provided with a rubber pad inside, and each of the limiting plates is marked with a serial number.
[0012] Compared with the prior art, this utility model provides a switch installation structure for a power distribution cabinet, which has the following advantages: In use, the air switch is installed from one end of the mounting block, allowing the two sliders on the back of the air switch to slide inside the two grooves for initial installation. Then, the air switch is slid left and right to the appropriate position, and then fixed by bolts to the connecting plate. Pulling the pull plate outward causes the locking rod to disengage from the groove. Then, the limiting plate is rotated to expose the wire groove, and the corresponding wire is then placed into the wire groove. Inside, the limiting plate on the rotating horizontal plate, corresponding to the wire groove, covers the wire groove. At this time, the movable groove on the limiting plate aligns with the slot on the horizontal plate. When the pulling plate is released, the locking rod inserts into the slot under the action of the spring to lock. At the same time, the iron block on the limiting plate will attract and fix the wire groove with the magnet on the horizontal plate. The rubber pad inside the wire groove can protect the wire. The serial number on the limiting plate can correspond to the circuit of the wire and the switch. This structure achieves quick positioning and installation of the switch through the slider and the sliding groove, and the stability is improved by bolt reinforcement. The wire groove and the limiting plate standardize the wire arrangement, the rubber pad protects the wire, and the serial number is easy to identify. Attached Figure Description

[0015] Please see Figure 1-3 , Example 1: A switch installation structure for a power distribution cabinet includes a mounting plate 1 and an air switch 2. A mounting block 3 is installed on the upper surface of the mounting plate 1. Slider 4 is fixedly installed on the top and bottom walls of the groove on the back of the air switch 2. Sliding grooves 5 are provided on the upper and lower surfaces of the mounting block 3. The two sliders 4 can slide inside the two sliding grooves 5 respectively. A horizontal plate 6 is fixedly connected to the surface of the mounting plate 1. A row of wire grooves 7 are opened on the surface of the horizontal plate 6. A row of limiting plates 8 are rotatably installed on the surface of the horizontal plate 6, and the limiting plates 8 correspond to the wire grooves 7.
[0016] Example 2: The difference between this example and Example 1 is that the upper and lower surfaces of the mounting block 3 are fixedly connected to the connecting plate 9, and the upper and lower surfaces of the air switch 2 are fixedly installed with the short plate 10. The surfaces of the short plate 10 and the connecting plate 9 are provided with matching screw holes 11.
[0017] Example 3: The difference between this example and Example 1 is that each limiting plate 8 has a set of movable grooves 12 on its surface, and each movable groove 12 has a locking rod 13 slidably fitted inside it. The surface of the horizontal plate 6 has multiple sets of locking slots 14 that match the locking rods 13, and each locking rod 13 has a spring 15 fitted on one side of its outer end.
[0018] Example 4: The difference between this example and Example 1 is that each set of levers 13 has a pull plate 16 fixedly connected to one end of its outer side.
[0019] Example 5: The difference between this example and Example 1 is that each limiting plate 8 has an iron block 17 embedded on its surface, and a row of magnets 18 is embedded on the surface of the horizontal plate 6.
[0020] Example 6: The difference between this example and Example 1 is that each groove 7 is provided with a rubber pad inside, and each limiting plate 8 is marked with a serial number.
[0021] In summary, the switch installation structure of this distribution cabinet allows for the initial installation of the air switch 2 by installing it from one end of the mounting block 3. This allows the two sliders 4 on the back of the air switch 2 to slide inside the two grooves 5. The air switch 2 is then initially installed by sliding it left and right to the appropriate position. Finally, it is fixed to the connecting plate 9 using bolts and short plates 10. Pulling the pull plate 16 outwards causes the locking rod 13 to disengage from the groove. Then, rotating the limiting plate 8 exposes the wire groove 7. Next, the corresponding wire is placed into the wire groove 7, and the corresponding wire on the horizontal plate 6 is rotated. The limiting plate 8 covers the wire groove 7. At this time, the movable groove 12 on the limiting plate 8 is aligned with the slot 14 on the horizontal plate 6. When the pulled plate 16 is released, the locking rod 13 is inserted into the slot 14 under the action of the spring 15 to achieve locking. At the same time, the iron block 17 on the limiting plate 8 will be attracted to the magnet 18 on the horizontal plate 6 for auxiliary fixation. The rubber pad in the wire groove 7 can protect the wire. The serial number on the limiting plate 8 can correspond to the circuit of the wire and the switch. This structure realizes the quick positioning and installation of the switch through the slider and the sliding groove, and the stability is improved by bolt reinforcement. The wire groove and the limiting plate standardize the wire arrangement, the rubber pad protects the wire, and the serial number is easy to identify.
