[0020] Figure 1 The internal structure schematic diagram of the nuclear power cabinet of the present utility model is shown. Figure 2 The partial enlarged view of the nuclear power cabinet of the present utility model at A is shown. Figure 3 The cross-sectional view of the grounding component in the nuclear power cabinet of the present utility model is shown. Please refer to Figure 1 , Figure 2 and Figure 3, A nuclear power cabinet, comprising a cabinet body 1, a door lock 2 and a grounding assembly 5. A door frame 11 is opened on the cabinet body 1, and a cabinet door 12 is arranged inside the door frame 11. The door lock 2 is arranged on the cabinet door 12, and a lock rod 3 is drivingly connected to the lock core 21 of the door lock 2. The lock rod 3 is vertically arranged. The grounding assembly 5 is arranged on the cabinet door 12, and the grounding assembly 5 is connected to a ground wire. The grounding assembly 5 includes a grounding base 51, an elastic member 53 and a support body 54. The elastic member 53 is arranged on the grounding base 51, and the elastic member 53 is in a compressed state. One end of the support body 54 contacts the elastic member 53, and the other end of the support body 54 vertically contacts the side surface of the lock rod 3. Among them, when the lock core 21 is rotated, the lock core 21 drives the lock rod 3 to move up and down, so that the lock rod 3 extends into or moves out of the inner side of the door frame 11, and the support body 54 slides on the lock rod 3. When the cabinet door 12 is closed, rotating the lock core 21 can drive the lock rod 3 to extend out and contact the inner side of the door frame 11, enhancing the connection strength between the cabinet door 12 and the cabinet body 1. At the same time, the contact area between the lock rod 3 and the cabinet door 12 is relatively large, and the lock rod 3 can evenly transmit force to the cabinet door 12, ensuring the stability performance when the cabinet door 12 is locked. A grounding assembly 5 is also arranged on the cabinet door 12. One end of the support body 54 in the grounding assembly 5 contacts the elastic member 53, and the other end vertically contacts the side surface of the lock rod 3. During the up and down movement of the lock rod 3, the elastic member 53 pushes the support body 54 to always contact the lock rod 3, so that a stable electrical connection is formed between the lock rod 3 and the grounding assembly 5, ensuring that the lock rod 3 is stably grounded and guaranteeing the safety performance of the nuclear power cabinet.

[0021] The specific structure of the door lock 2 is described as follows:

[0022] Figure 4 The schematic diagram of the cooperation structure between the door lock and the lock rod in the nuclear power cabinet of the present invention is shown. Please refer to Figure 4 , The door lock 2 further includes a rack 23. A tooth portion 22 is circumferentially arranged on the lock core 21 and meshes with the rack 23, and the lock rod 3 is connected to the rack 23. When the lock core 21 is rotated, the lock core 21 drives the lock rod 3 to move upward or up and down through the meshing of the tooth portion 22 and the rack 23. The gear-rack structure is adopted for transmission. The gear-rack transmission structure has a large load capacity and a wide speed range, and can adapt to operators to turn the lock core 21 at different speeds. Moreover, the gear-rack transmission structure has a simple structure, is easy to manufacture and maintain, and has a low cost.

[0023] The door lock 2 further includes a lock case 24. A waist-shaped hole 25 is opened on the lock case 24, and the length direction of the waist-shaped hole 25 is consistent with the moving direction of the lock rod 3. Specifically, after the rack 23 is snapped into and passes through the waist-shaped groove, it is then connected to the lock rod 3. The waist-shaped hole 25 plays a guiding role to ensure that the lock rod 3 moves along the length direction of the waist-shaped groove, that is, the lock rod 3 moves along the vertical direction.

[0024] The specific structures of the guiding seat 4 and the wiring base are described as follows:

[0025] Please refer to Figure 1 ,Figure 3 and Figure 4 Moreover, a guide seat 4 is further provided on the cabinet door 12. A chute 41 is formed on the guide seat 4, and the lock rod 3 passes through the chute 41. The chute 41 restricts the movement of the lock rod 3 along the direction of the chute 41, increasing the stability of the lock rod 3 during sliding. At the same time, when the cabinet door 12 is closed and the lock rod 3 abuts against the inner side of the door frame 11, the force transmitted from the door frame 11 to the cabinet door 12 can be transmitted to the cabinet door 12 through multiple guide seats 4. The force transmission of multiple guide seats 4 makes the force acting on the cabinet door 12 more evenly distributed. A cylinder body 52 is provided on the grounding base 51, and an elastic member 53 and a support body 54 are arranged inside the cylinder body 52. The support body 54 is arranged inside the cylinder body 52 and is guided by the cylinder body 52. The cylinder body 52 increases the stability of the support body 54 during movement, ensuring a stable connection between the support body 54 and the lock rod 3.

[0026] In addition, the support body 54 is a sphere or a rod. When the support body 54 is a rod, the end of the support body 54 in contact with the lock rod 3 is an arc surface to reduce the friction between the support body 54 and the lock rod 3.

[0027] The specific structure of the lock rod 3 is described as follows:

[0028] Please refer to Figure 1 and Figure 4 When the cabinet door 12 is closed, a step is formed due to the unevenness between the inner side of the cabinet door 12 and the inner side of the door frame 11. A bent portion 31 is provided at one end of the lock rod 3 away from the door lock 2. When the cabinet door 12 is closed, the bent portion 31 fits against the door frame 11. The bent portion 31 is provided corresponding to the step between the cabinet door 12 and the door frame 11, enabling the lock rod 3 to better fit against the door frame 11, increasing the contact area between the lock rod 3 and the door frame 11, and making the force conduction between the lock rod 3 and the door frame 11 more stable. In practical use, the bent portion 31 needs to switch between two states of fitting against the door frame 11 and being away from the door frame 11, and the wear of the bent portion 31 is relatively large. The bent portion 31 is movably connected to the lock rod 3, facilitating the replacement of the worn bent portion 31. A roller 32 is provided at the end of the lock rod 3 away from the door lock 2 to reduce the wear between the lock rod 3 and the door frame 11.

[0029] The specific working process of the present utility model is as follows:

[0030] When closing the nuclear power cabinet, first close the cabinet door 12, and then turn the lock core 21. The rotation of the lock core 21 drives the rack 23 engaged with the tooth portion 22 of the lock core 21. The rack 23 extends along the kidney-shaped groove, and then drives the lock rod 3 connected to the rack 23 to extend. Until the rack 23 moves to the end of the kidney-shaped groove, at this time, the bent portion 31 contacts the inner side of the door frame 11, and the nuclear power cabinet is closed. During the movement of the lock rod 3, the support body 54 is always in contact with the lock rod 3 under the push of the elastic member 53.

[0031] When opening the nuclear power cabinet, turn the lock core 21 counterclockwise. The rotation of the lock core 21 drives the rack 23 that meshes with the tooth part 22 of the lock core 21, and the rack 23 retracts along the kidney-shaped slot, thereby driving the lock rod 3 connected to the rack 23 to retract. Until the rack 23 moves to the end of the kidney-shaped slot, at this time the bent part 31 is away from the door frame 11, rotate to open the cabinet door 12, and the nuclear power cabinet is opened. During the movement of the lock rod 3, the support body 54 is always in contact with the lock rod 3 under the push of the elastic member 53.

[0032] It can be seen that in the above nuclear power cabinet, during the up and down movement of the lock rod 3, the elastic member 53 pushes the support body 54 to always be in contact with the lock rod 3, so that a stable electrical connection is formed between the lock rod 3 and the grounding assembly 5, ensuring that the lock rod 3 is stably grounded and guaranteeing the safety performance of the nuclear power cabinet.

[0033] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0034] The above embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
