[0024] As Figure 1 shown;

[0025] An anti-theft power distribution cabinet that is convenient for maintenance, including the power distribution cabinet body 1.

[0026] In this implementation: The power distribution cabinet, also known as the distribution box, is a general term for the motor control center. The power distribution cabinet is a complete set of devices that centrally and enclosedly install switches, meters and other equipment. The main function of the power distribution cabinet is to facilitate power outage and power-on, and play the roles of metering and protection. They are commonly used in the links of power generation, power transmission, power distribution, power conversion and consumption in the power system, and are used to control, protect and monitor circuits. When the staff maintains the distribution box, they need to frequently open and close the cabinet door 21, and each time they need to lock the cabinet door 21 to limit its position, which is rather cumbersome. Now, a mechanism that can quickly fix the cabinet door 21 is needed to facilitate the staff to open and close the cabinet door 21, thereby improving the maintenance efficiency of the staff for the power distribution cabinet. To solve this technical problem, a switch assembly 2 is added on this basis.

[0027] Furthermore:

[0028] As Figures 1 to 4 shown:

[0029] In combination with the above content: the switch assembly 2 includes a cabinet door 21, a fixed collar 22, a first limiting ring 23 and a first spring 211, the cabinet door 21 is rotatably connected to the outer side of the end of the distribution cabinet body 1, the fixed collar 22 is fixedly connected to the inner side of the end of the cabinet door 21, the fixed collar 22 has a through groove and is slidably connected to the inside of the push rod 24, the first limiting ring 23 is fixedly connected to the inner side of the end of the fixed collar 22, the outer surface of the push rod 24 is fixedly connected to the sliding sleeve 25, the outer surface of the sliding sleeve 25 is also fixedly connected to the second limiting ring 26, the outer side of the end of the push rod 24 is slidably connected to the toggle piece 27, and the outer surface of the end of the push rod 24 close to the toggle piece 27 A top ball 28 is fixedly connected, a connecting block 29 is fixedly connected to the inner side of the end of the distribution cabinet body 1, a limiting block 210 is slidably connected inside the connecting block 29, the outer sides of both ends of the first spring 211 are respectively fixedly connected to the outer side of the end of the limiting block 210 and the inner side of the end of the connecting block 29, a locking ring 212 is detachably connected to the outer side of the end of the push rod 24, a locking block 213 is installed on the inner side of the end of the locking ring 212, a limiting slide groove 217 is provided on the inner side of the end of the connecting block 29, a limiting slide rod 216 is fixedly connected to the outer side of the end of the limiting block 210, and the outer surface of the limiting slide rod 216 is slidably connected to the inner wall surface of the limiting slide groove 217.

[0030] In this implementation: When the staff maintains the distribution box, first open the lock ring 212 through the lock block 213 and remove the lock ring 212 from the outer side of the end of the push rod 24. At this time, the top ball 28 is located on one side of the limit block 210, and the limit block 210 limits the position of the top ball 28. When it is necessary to open the cabinet door 21, just push the push rod 24 inward. The push rod 24 pushes the toggle piece 27 to move through the second limit ring 26. When the toggle piece 27 contacts the outer side of the end of the limit block 210, it will push the limit block 210 to contract into the inside of the connecting block 29. Then the toggle piece 27 will move to the other side of the limit block 210. At this time, pull the push rod 24 again, and the limit block 210 drives the toggle piece 27 to slide on the outer surface of the push rod 24 until the toggle piece 27 contacts the top ball 28. At this time, continue to pull the push rod 24. Since both ends of the toggle piece 27 have arc surfaces, the limit block 210 will slide along the arc surface of the toggle piece 27 and then straddle both the toggle piece 27 and the top ball 28 at the same time. At this time, the limit block 210 loses the function of fixing and positioning the top ball 28, and the staff can maintain the circuit inside the power distribution cabinet body 1. When the staff wants to close the cabinet door 21 again, just push the cabinet door 21 so that the cabinet door 21 is attached to the outer side of one end of the power distribution cabinet body 1, and then push the push rod 24. When the top ball 28 at the end of the push rod 24 contacts the inclined surface at the end of the limit block 210, the arc surface of the top ball 28 forces the two limit blocks 210 to move into the inside of the connecting block 29. At this time, continue to push the push rod 24 so that the outer side of the end of the limit block 210 abuts against the outer side of one end of the top ball 28. By limiting the position of the limit slide bar 216 through the limit slide groove 217, the limit block 210 can slide more stably. At this time, the quick fixing function of the cabinet door 21 is completed. When it is necessary to lock the cabinet door 21, just open the lock ring 212 again, then sleeved it on the outer side of the end of the push rod 24, and lock the fixed collar 22 through the lock block 213. At this time, if the lock ring 212 is not removed, the push rod 24 cannot be pushed continuously, and the cabinet door 21 cannot be opened, completing the locking function of the cabinet door 21. Through the push rod 24, the staff can simplify the operation process, allowing the staff to quickly and easily open and close the power distribution cabinet, thus greatly reducing the time required to switch the power distribution cabinet. The simple push-pull form greatly reduces the situation of staff operation errors and increases the practicability of the device.

[0031] In an alternative embodiment, a second spring 214 is sleeved on the outer side of the end of the push rod 24. The two outer ends of the second spring 214 are respectively fixedly connected to the inner end of the top ball 28 and the outer end of the toggle piece 27. A groove matching the shape of the toggle piece 27 is formed in the inner end of one end of the top ball 28.

[0032] In this implementation: A groove is provided on the inner side of one end of the top ball 28. When the limit catch 210 abuts against the toggle piece 27 and moves towards the position of the top ball 28, the outer side of one end of the toggle piece 27 can be snapped into the interior of the top ball 28, thereby making the gap between the toggle piece 27 and the top ball 28 smaller, enabling the limit catch 210 to more smoothly straddle the toggle piece 27 and the top ball 28, and increasing the success rate of opening the fixed collar 22.

[0033] Furthermore:

[0034] In an alternative embodiment, the two connecting blocks 29 and the limit catch 210 are symmetrically arranged on the inner side of the end of the power distribution cabinet body 1.

[0035] In this implementation: The top ball 28 is fixed simultaneously by the two symmetrical connecting blocks 29 and the limit catch 210, increasing the firmness of the fixation of the top ball 28. At the same time, the pressure on one of the limit catches 210 can be shared by the two symmetrical limit catches 210, increasing the service life of the device.

[0036] Furthermore:

[0037] In an alternative embodiment, a push-pull ring 215 is fixedly connected to the outer side of the end of the push rod 24.

[0038] In this implementation: The push-pull ring 215 consists of two annular structures. The push-pull ring 215 conforms to ergonomics. When the staff operates the push rod 24, the fingers can be inserted into the interior of the push-pull ring 215, which can help the user more easily push and pull the push rod 24, enhancing the user experience and increasing work efficiency at the same time.

[0039] Working principle: When maintenance personnel perform maintenance on the distribution box, first open the lock ring 212 through the lock block 213 and remove the lock ring 212 from the outer side of the end of the push rod 24. At this time, the top ball 28 is located on one side of the limit block 210, and the position of the top ball 28 is limited by the limit block 210. When it is necessary to open the cabinet door 21, simply push the push rod 24 inward. The push rod 24 drives the toggle piece 27 to move through the second limit ring 26. When the toggle piece 27 contacts the outer side of the end of the limit block 210, it will push the limit block 210 to contract into the inside of the connecting block 29. Then, the toggle piece 27 will move to the other side of the limit block 210. At this time, pull the push rod 24 again, and the limit block 210 drives the toggle piece 27 to slide on the outer surface of the push rod 24 until the toggle piece 27 contacts the top ball 28. At this time, continue to pull the push rod 24. Since both ends of the toggle piece 27 have arc surfaces, the limit block 210 will slide along the arc surface of the toggle piece 27 and then straddle both the toggle piece 27 and the top ball 28 at the same time. At this time, the limit block 210 loses the function of fixing and positioning the top ball 28, and the maintenance personnel can maintain the circuits inside the power distribution cabinet body 1. When the maintenance personnel want to close the cabinet door 21 again, simply push the cabinet door 21 so that the cabinet door 21 is attached to the outer side of one end of the power distribution cabinet body 1, and then push the push rod 24. When the top ball 28 at the end of the push rod 24 contacts the inclined surface at the end of the limit block 210, the arc surface of the top ball 28 will force the two limit blocks 210 to move into the inside of the connecting block 29. At this time, continue to push the push rod 24 so that the outer side of the end of the limit block 210 abuts against the outer side of one end of the top ball 28. By limiting the position of the limit slide rod 216 through the limit slide groove 217, the sliding of the limit block 210 can be made more stable. At this time, the quick fixing function of the cabinet door 21 is completed. When it is necessary to lock the cabinet door 21, simply open the lock ring 212 again, then sleeve it on the outer side of the end of the push rod 24, and lock the fixed collar 22 through the lock block 213. At this time, if the lock ring 212 is not removed, the push rod 24 cannot be pushed continuously, and the cabinet door 21 cannot be opened, thus completing the locking function of the cabinet door 21. Through the push rod 24, the maintenance personnel can simplify the operation process, allowing the maintenance personnel to quickly and easily open and close the power distribution cabinet, thereby greatly reducing the time required to switch the power distribution cabinet. The simple push-pull form greatly reduces the situation of operation errors by the maintenance personnel and increases the practicability of the device. A groove is provided on the inner side of one end of the top ball 28. When the limit block 210 abuts against the toggle piece 27 and moves towards the position of the top ball 28, the outer side of one end of the toggle piece 27 can be clamped into the inside of the top ball 28, thereby making the gap between the toggle piece 27 and the top ball 28 smaller, enabling the limit block 210 to more smoothly straddle the toggle piece 27 and the top ball 28, and increasing the success rate of opening the fixed collar 22. By simultaneously fixing the top ball 28 through the two symmetric connecting blocks 29 and limit blocks 210, the firmness of fixing the top ball 28 is increased.Meanwhile, the pressure on one of the limiting blocks 210 can be shared by two symmetric limiting blocks 210, which increases the service life of the device. The push-pull ring 215 consists of two annular structures. The push-pull ring 215 conforms to ergonomics. When the staff operates the push rod 24, they can insert their fingers into the push-pull ring 215, which can help the user push and pull the push rod 24 more easily, enhancing the user experience and increasing work efficiency at the same time.
