[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Example 1: See Figures 1 to 11The power distribution cabinet in this embodiment includes a cabinet body 1 and a cabinet door 2 that are hinged together. The right side of the cabinet door 2 is hinged to the right side of the cabinet body 1 via a door hinge. A partition 3 is fixed inside the cabinet body 1, which divides the cabinet body 1 into an upper power distribution compartment 4 and a lower power distribution compartment 5. The upper power distribution compartment 4 is used to accommodate the high-voltage system 6 to form a high-voltage area, and the lower power distribution compartment 5 is used to accommodate the control system 7 to form a control area. The partition 3 is fixed in the middle position inside the cabinet body 1 to divide the high-voltage area and the control area equally to achieve a separated layout. The top surface of the partition 3 is provided with a through hole that runs vertically through the top. The through hole is located on the inner side of the leftmost end of the top surface of the partition 3. The through hole connects the high-voltage area and the control area for electrical connection between the high-voltage system 6 and the control system 7. Several control buttons 8 are provided on the front of the partition 3. The control buttons 8 are located on the right side of the front of the partition 3. The control buttons 8 include a start button, a stop button, a reset button, and an emergency stop button to realize specific operations. The partition 3 has a rotating pin 9 on the front, and a pin seat 10 is fixed on the back of the cabinet door 2. When the cabinet door 2 rotates around the door hinge to close, the cabinet door 2 drives the rotating pin 9 to rotate and insert into the pin seat 10. This cleverly utilizes the structure of the partition 3 itself to install the rotating pin 9, thereby effectively making full use of the partition 3 and making the internal layout of the power distribution cabinet more reasonable.

[0033] The cabinet door 2 is also fixed with a first trigger 11. The cabinet body 1 is also provided with a rotating block 12, a sliding block 13, a spring 14 and a second trigger 15 corresponding to the pin seat 10. The rotating pin 9 is fixed on the left side of the rotating block 12 and located at the left end of the front of the partition 3. The sliding block 13 is always in contact with the rotating block 12 under the action of the spring 14. The rotating shaft 16 is fixed at the center of the rotating block 12. After the rotating shaft 16 extends out of the rotating block 12, it is fixedly connected to the second trigger 15. There are two first triggers 11 and two triggers 15. The two first triggers 11 are fixed at the upper and lower ends of the left side of the back of the cabinet door 1, and the two second triggers 15 are fixed at the upper and lower ends of the rotating shaft 16, respectively. The second trigger 15 is a rotating hook. The two rotating hooks are rotatably installed on the top and bottom of the cabinet body 1, respectively. The first trigger 11 is a fixed hook that can turn the rotating hook. During the process of closing the cabinet door 2 by rotating around the door hinge, the first trigger 11 contacts and triggers the second trigger 15. The second trigger 15 drives the rotating pin 9 to rotate through the rotating shaft 16 and the rotating block 12, so that the rotating pin 9 can be inserted into the pin seat 10. After the rotating pin 9 is inserted into the pin seat 10, the contact area between the sliding block 13 and the rotating block 12 is maximized, making the cabinet door 2 more securely locked and highly safe. A greater force must be used to open the cabinet door 2. Therefore, this embodiment has the advantages of simple structure and high safety. Specifically, the rotating pin 9 is arc-shaped, and the pin seat 10 has a horizontally arranged pin hole. The diameter of the pin hole is larger than the longitudinal dimension of the rotating pin 9 to facilitate the smooth insertion of the rotating pin 9. The rotating block 12 has a first inclined surface 17 and an arc surface 18, which are connected to each other. The first inclined surface 17 and the arc surface 18 are arranged sequentially from the inside to the outside on the right side of the rotating block 12. The sliding block 13 has a straight surface 19 and a second inclined surface 20, which are connected to each other. The sliding block 13 is arranged sequentially from the inside to the outside on the left side of the sliding block 13. When the rotating pin 9 is not inserted into the pin seat 10, the arc surface 18 contacts the straight surface 19, and the contact area is small. When the rotating pin 9 is inserted into the pin seat 10, the first inclined surface 17 contacts the second inclined surface 20, and the contact area is large. That is, after the rotating pin 9 is inserted into the pin seat 10, the sliding block 13 and the rotating block 12 are in inclined contact, which makes the rotating block 12 need to overcome a large force to rotate and even make the rotating pin 9 disengage from the pin seat 10, thus improving the reliability of locking.

[0034] Example 2: Unlike Example 1, there is only one first trigger 11 and one second trigger 15. The first trigger 11 is fixed to the upper left side of the back of the cabinet door 2, and the second trigger 15 is fixed to the upper end of the rotating shaft 16.

[0035] Example 3: Unlike Example 1, there is only one first trigger 11 and one second trigger 15. The first trigger 11 is fixed to the lower left side of the back of the cabinet door 2, and the second trigger 15 is fixed to the lower end of the rotating shaft 16.

[0036] Example 4: Unlike Example 1, see [link to example]. Figures 12 to 16 The front of the cabinet door 1 is provided with a safety pin 21 for limiting the sliding of the sliding block 13. For this purpose, the front of the cabinet door 1 is provided with a socket 22 for the safety pin 21 to be inserted. The front of the sliding block 13 is provided with a safety seat 23. The safety pin 21 is inserted into the safety seat 23 through the socket 22. In this way, the cabinet door 2 cannot be opened without removing the safety pin 21, thereby further improving the reliability of the lock.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
