[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] As shown in Figures 1-6, a distribution cabinet lock body structure includes a cabinet body 1 with a hinged door 2. The door 2 is hinged to the cabinet body 1. The outer surface of the door 2 is provided with a hinge latch plate 3, and the outer surface of the cabinet body 1 is provided with a latch seat 4 that cooperates with the hinge latch plate 3. The hinge latch plate 3 and the latch seat 4 are locked together by a padlock 5. The hinge latch plate 3 is hung on the latch seat 4, and then locked by the padlock 5 (refer to Figure 2 in the specification). The outer surface of the cabinet body 1 has an installation cavity 7, and the installation cavity 7 is provided with a locking component that cooperates with the hinge latch plate 3. Since the hinge latch plate 3 and the latch seat 4 cooperate to achieve the effect of closing the door 2, the hinge latch plate 3 and the latch seat 4 can directly swing, resulting in a gap after the door 2 is closed. Therefore, the locking component further ensures the stability of the door 2 when closed.

[0032] Furthermore, the locking assembly includes a mounting plate 8 that is elastically connected and slidably disposed inside the mounting cavity 7, and a plug rod 11 that is movably disposed through the side wall of the cabinet 1. One end of the plug rod 11 is fixedly connected to one side of the mounting plate 8. The surface of the cabinet door 2 is provided with a socket 6 that mates with the plug rod 11. The other side of the mounting plate 8 is provided with a pressure-bearing component that is pressed by the hinge latch plate 3, thereby causing the mounting plate 8 to move. After the cabinet door 2 is closed, the hinge latch plate 3 is hung on the latch seat 4. The hinge latch plate 3 will press the pressure-bearing component, thereby causing the mounting plate 8 to move. The movement of the mounting plate 8 causes the plug rod 11 to move, thereby causing the plug rod 11 to insert into the socket 6, that is, to limit the cabinet door 2 after it is closed, and to ensure the stability of the cabinet door 2 after it is closed.

[0033] Furthermore, the pressure-bearing component includes a rod and a fixing plate 9. The fixing plate 9 is fixedly connected to one side of the mounting plate 8. One end of the rod extends through the surface of the locking seat 4, and the other end of the rod is provided with a guide rod 18. The surface of the fixing plate 9 is provided with a guide groove 14 for sliding connection of the guide rod 18. In use, the hinge locking piece 3 presses the rod, and the rod moves into the mounting cavity 7 under pressure (refer to Figure 3 in the specification). The pressure and movement of the rod drives the guide rod 18 to move. With the cooperation of the guide rod 18 and the guide groove 14, the fixing plate 9 moves, which drives the mounting plate 8 to move, thus realizing the movement of the mounting plate 8 and the movement of the insertion rod 11 as described in the previous paragraph.

[0034] Furthermore, there are two pressure-bearing components that are symmetrically distributed. The guide rod 18 is a bolt that passes through the guide groove 14 and is threaded to the rod body. During installation, the worker passes the bolt through the guide groove 14 and threaded it to the rod body. The bolt is threaded only at one end near the rod body, and the rest of the surface is smooth (see Figure 5 in the instruction manual).

[0035] Furthermore, the rod body includes a pressure rod 17 and a connecting plate 19 fixed on the outer surface of the pressure rod 17. The connecting plate 19 is parallel to the pressure rod 17. The surface of the locking seat 4 is provided with a through hole 16 that mates with the pressure rod 17. With the assistance of the connecting plate 19, the connecting plate 19 is attached to the surface of the fixing plate 9, which facilitates the threaded connection between the guide rod 18 and the rod body.

[0036] Furthermore, there are multiple insertion rods 11, each threadedly connected to the mounting plate 8, facilitating installation and disassembly by workers. A mounting rod 13 is threaded through the surface of the mounting plate 8. One end of the mounting rod 13 is threadedly connected to the inner wall of the mounting cavity 7. A spring 10 is fitted onto the outer side of the mounting rod 13. One end of the spring 10 contacts the inner wall of the mounting cavity 7, and the other end contacts the surface of the mounting plate 8. During installation, workers place the mounting plate 8 into the mounting cavity 7, then move the mounting rod 13 through the mounting plate 8, fit the spring 10 onto the outer side of the mounting rod 13, and then thread the mounting rod 13 to the inner wall of the mounting cavity 7. The insertion rods 11 can then be threadedly connected subsequently.

[0037] Furthermore, a sealing gasket 15 is provided between the latch seat 4 and the cabinet body 1. A sealing groove 12 that matches the sealing gasket 15 is opened on the outer surface of the cabinet body 1. The size of the latch seat 4 is larger than the size of the mounting cavity 7. After the latch seat 4 is installed on the cabinet body 1, it will completely cover the mounting cavity 7. By setting the sealing gasket 15, the sealing of the connection between the latch seat 4 and the cabinet body 1 is guaranteed.

[0038] Furthermore, the hinge latch plate 3 is fixedly connected to the cabinet door 2 by screws, and the latch seat 4 is fixedly connected to the cabinet body 1 by screws. This part is existing technology and will not be described in detail.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
