Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present utility model.

[0030] Please refer to Figures 1-9 , the present utility model provides a technical solution: a double-hole contact structure for a high-voltage cabinet, including a double-hole contact body 1, a mounting plate 3 and a high-voltage cabinet body 2. The mounting plate 3 is slidably inserted on the left outer wall of the high-voltage cabinet body 2. There is a mounting hole on the left outer wall of the high-voltage cabinet body 2 that communicates with its inner cavity. The double-hole contact body 1 is located inside the mounting hole on the left outer wall of the high-voltage cabinet body 2. A fixing rod 4 in the shape of an L is fixed on the left surface of the double-hole contact body 1. A connecting rod 5 is fixed between the fixing rod 4 and the mounting plate 3. Two symmetrically arranged limiting plates 6 are fixed on the left surface of the high-voltage cabinet body 2 and are respectively located on the front and back sides of the mounting plate 3. It further includes:

[0031] A limiting mechanism 7, which is arranged on the left surface of the mounting plate 3 and is used to limit the mounting plate 3. The limiting mechanism 7 includes two symmetrically fixed fixing plates 71 on the left surface of the mounting plate 3, two rotating columns 72 rotatably connected to the same-side fixing plate 71, a bidirectional lead screw 73 coaxially fixed between the two rotating columns 72, two moving rods 74 in the shape of an L and threadedly connected to the bidirectional lead screw 73, a rotating rod 77 coaxially fixed on the surface of one of the rotating columns 72 away from the bidirectional lead screw 73, and a motor 710 installed on the surface of one of the fixing plates 71 away from the bidirectional lead screw 73 and used to drive the rotating rod 77 to rotate. The two moving rods 74 are symmetrically arranged and slidably connected to the left surface of the mounting plate 3, and a number of limiting rods 75 slidably inserted into the same-side limiting plate 6 are fixed on the opposite sides of the vertical rod ends of the two moving rods 74. By setting the fixing rod 4, the connecting rod 5 and the mounting plate 3, the double-hole contact body 1 can be installed inside the mounting hole on the left outer wall of the high-voltage cabinet body 2. By setting the two limiting plates 6 and the limiting mechanism 7, the mounting plate 3 can be limited, so that the double-hole contact body 1 can be limited, which is convenient for the installation and disassembly of the double-hole contact body 1 and avoids the situation that the disassembly is difficult due to rusting in the fixing method by screws or bolts.

[0032] In this embodiment, the limiting mechanism 7 also includes two sprockets 78 located on the left side of the mounting plate 3 and connected by a chain 79, and a rotating shaft 711 coaxially connected to the output shaft of the motor 710, and the two sprockets 78 are coaxially fixed on the circumferential outer walls of the rotating shaft 711 and the rotating rod 77, respectively, which can smoothly drive the rotating rod 77 to rotate, and further can smoothly drive the bidirectional screw rod 73 to rotate.

[0033] In addition, a guide groove is provided on the left surface of the mounting plate 3, and a guide block 76 is fixed on the right surface of the cross bar end of the moving rod 74, which is slidably connected to the guide groove on the left surface of the mounting plate 3, so as to guide the movement of the moving rod 74 and indirectly guide the movement of several limit rods 75.

[0034] Furthermore, the opposite surfaces of the two limiting plates 6 are provided with a plurality of limiting holes, and the limiting rods 75 are slidably plugged into the limiting holes on the same side of the outer wall of the limiting plate 6 on the same side, so that the plurality of limiting rods 75 can be smoothly plugged into the two limiting plates 6 together.

[0035] Specifically, two symmetrical handles 9 are fixed to the left surface of the mounting plate 3 , and the handles 9 are U-shaped, so that the mounting plate 3 can be easily taken or placed.

[0036] It is worth noting that the left side surface of the high-voltage cabinet body 2 is provided with a plurality of slots, and the right side surface of the mounting plate 3 is fixed with an insert block 8 which is slidably plugged into the slot on the same side of the left side surface of the high-voltage cabinet body 2, and can guide the disassembly and assembly of the mounting plate 3.

[0037] It is worth mentioning that the limiting mechanism 7 also includes a protective box 712 fixed on the surface of one of the fixed plates 71 away from the bidirectional screw rod 73. The motor 710 is located inside the protective box 712, and the rotating shaft 711 passes through the outer wall of the protective box 712 away from the bidirectional screw rod 73, which can protect the motor 710 and extend the service life of the motor 710.

[0038] It is worth emphasizing that the longitudinal cross-section of the guide groove on the left side surface of the mounting plate 3 is in a convex shape, and the shape of the guide block 76 is in a convex shape that matches the shape of the guide groove on the left side surface of the mounting plate 3, which can make the connection between the guide block 76 and the guide groove on the left side surface tighter, and indirectly make the several limit rods 75 more stable during the movement.

[0039] Finally, it should be noted that components such as the double-hole contact body 1, the high-voltage cabinet body 2, and the motor 710 involved in the present utility model are all common standard components or components known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the adapted controllers and power supplies, are connected by wires. The specific connection means should refer to the working principle of the present utility model. The electrical components are electrically connected in accordance with the sequence of their successive operations. All their detailed connection means are well-known techniques in the art.

[0040] In the specific use process of this embodiment, when it is necessary to disassemble the double-hole contact body 1, first, start the motor 710 through an external PLC. The output shaft of the motor 710 rotates to drive the coaxial connected rotating shaft 711 to rotate. The rotation of the rotating shaft 711 drives the same-side sprocket 78 coaxially fixed thereto to rotate. The rotation of this sprocket 78 drives another sprocket 78 connected to it by a chain 79 to rotate. The rotation of the other sprocket 78 drives the same-side rotating column 72 coaxially fixed thereto to rotate. The rotation of this rotating column 72 drives the coaxial double-threaded screw rod 73 to rotate. The rotation of the double-threaded screw rod 73 drives the two moving rods 74 threadedly connected thereto to approach each other. The moving rods 74 move under the guiding action of the same-side guiding blocks 76 and the guiding grooves on the left surface of the mounting plate 3. The movement of the moving rods 74 drives the several limiting rods 75 fixed thereto to move. When several limiting rods 75 are completely separated from the limiting holes on the outer wall of the same-side limiting plate 6, turn off the motor 710 through the external PLC;

[0041] Immediately afterwards, pull the two handles 9. Through the two handles 9, the mounting plate 3 can be driven to move. The movement of the mounting plate 3 drives the several insertion blocks 8 to move. When several insertion blocks 8 are all separated from the same-side slots on the outer wall of the high-voltage cabinet body 2 and the double-hole contact body 1 is separated from the mounting holes on the outer wall of the high-voltage cabinet body 2, the disassembly work of the double-hole contact body 1 is completed.

Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments.
