[0020] Figure 1 The three-dimensional structural schematic diagram of the double-door nuclear power cabinet of the present utility model is shown. Figure 2 The three-dimensional structural schematic diagram of the double-door nuclear power cabinet of the present utility model with the cabinet body hidden is shown. Figure 3 The partial enlarged view of the double-door nuclear power cabinet of the present utility model at A is shown. Please refer to Figure 1 , Figure 2 and Figure 3, a double - door nuclear power cabinet, which includes a cabinet body 1, a left door panel 2, a right door panel 3 and a door lock 4. A door frame 11 is provided on the cabinet body 1. For the left door panel 2 and the right door panel 3, the left side of the left door panel 2 is rotatably connected to the door frame 11, and the right side of the right door panel 3 is rotatably connected to the door frame 11. For the door lock 4, two door locks 4 are respectively provided on the left door panel 2 and the right door panel 3. Among them, a lock piece 42 is rotatably provided on the part of the door lock 4 extending into the cabinet body 1, and lock rods 5 are respectively connected to both ends of the lock piece 42 in terms of length. After the left door panel 2 and the right door panel 3 are closed, when the lock piece 42 is vertically arranged, the end of the lock rod 5 far from the lock piece 42 extends into the inner side of the door frame 11. When the lock piece 42 is horizontally arranged, the end of the lock rod 5 far from the lock piece 42 retracts and is only located inside the left door panel 2 or the right door panel 3. By rotating the lock piece 42 with the door lock 4, the rotating lock piece 42 can drive the lock rod 5 to move up and down, so that the lock rod 5 retracts inside the left door panel 2 and the right door panel 3, or extends into the inner side of the door frame 11. After the lock rod 5 extends into the inner side of the door frame 11, at this time, in addition to being fixed by the door lock 4, the left door panel 2 and the right door panel 3 are also restricted in position by the protruding lock rod 5. Multiple lock rods 5 cooperate with the door lock 4 to restrict the positions of the left door panel 2 and the right door panel 3 from multiple positions, ensuring the structural strength after the left door panel 2 and the right door panel 3 are closed, making the connection between the left door panel 2 and the right door panel 3, and between each door panel and the door frame 11 more stable, and further ensuring the sealing performance of the nuclear power cabinet.

[0021] The specific structures of the left door panel 2, the right door panel 3 and the door frame 11 are described as follows:

[0022] Figure 4 The schematic diagram of the cooperation mechanism between the left door panel, the right door panel and the door frame in the double - door nuclear power cabinet of the present utility model is shown. Please refer to Figure 4 , an inward bend is formed on the right side of the left door panel 2 to form a first groove 21, and a first bent part 31 is provided on the right door panel 3. When the left door panel 2 and the right door panel 3 are arranged parallel to the door frame 11, the first bent part 31 is snapped into the first groove 21. The settings of the first groove and the first bent part 31 increase the surface contact between the left door panel 2 and the right door panel 3, thereby enhancing the sealing performance between the left door panel 2 and the right door panel 3. In addition, a sealing elastic member 22 is provided in the first groove 21. The sealing elastic member 22 has good compression performance and can fill the sealing gap through compression deformation, thereby effectively enhancing the sealing performance.

[0023] Please refer to Figure 4 , further, a second groove 13 is circumferentially provided on the door frame 11, and the notch of the second groove 13 faces outward. Second bent parts 14 are provided on the sides of the left door panel 2 and the right door panel 3 and are snapped into the second groove 13. The settings of the second groove 13 and the second bent parts 14 increase the surface contact between the left door panel 2 and the cabinet body 1, and increase the surface contact between the right door panel 3 and the cabinet body 1, thereby enhancing the sealing performance between the left door panel 2 and the right door panel 3 and the cabinet body 1.

[0024] Please refer to Figure 1 and Figure 2 The left door panel 2 and the right door panel 3 are hinged to the door frame 11. The hinged structure occupies little space and has a simple structure, which is easy to maintain. A baffle 12 is provided on the door frame 11. The baffle 12 is parallel to the door frame 11 and is provided on the rotation path of the left door panel 2 and the right door panel 3 to limit the rotation of the left door panel 2 and the right door panel 3, so as to prevent the left door panel 2 and the right door panel 3 from being rotated into the cabinet body 1 and damaging the device inside the cabinet body 1.

[0025] The specific structure of the fixing base 7, the connecting member 6 and the door lock 4 is described below:

[0026] Please refer to Figure 2 and Figure 3 , a fixing seat 7 is provided on the inner side of the left door panel 2 and the right door panel 3, a transverse slide groove 71 is provided on the fixing seat 7, and the lock rod 5 passes through the slide groove 71. When the left door panel 2 and the right door panel 3 are closed, the door frame 11 transmits the force restricting the opening of the left door panel 2 and the right door panel 3 to the left door panel 2 and the right door panel 3 evenly through the lock rod 5 and the fixing seat 7, so as to ensure that the force at each part of the left door panel 2 and the right door panel 3 is evenly applied, so that the two can fit better and ensure the sealing performance of the two. A connecting member 6 is also included, one end of the connecting member 6 is rotatably connected to the locking plate 42, and the other end of the connecting member 6 is provided with a connecting hole 61, and the lock rod 5 extends into the connecting hole 61, and a fastening hole 62 is provided on the hole wall of the connecting hole 61. After the lock rod 5 extends into the connecting hole 61, the lock rod 5 and the connecting member 6 can be conveniently connected by screwing the screw into the fastening hole 62.

[0027] Please refer to Figure 2 and Figure 3 , an extended lock portion 43 is provided on the lock plate 42 on the right door panel 3. When the lock rod 5 extends into the inner side of the door frame 11, the extended lock portion 43 extends into the inner side of the left door panel 2 to limit the positional relationship between the right door panel 3 and the left door panel 2. When the lock rod 5 is retracted and is only located on the inner side of the left door panel 2 or the right door panel 3, the extended lock portion 43 is also completely located on the inner side of the right door panel 3, and no longer limits the positional relationship between the right door panel 3 and the left door panel 2. The door lock 4 includes a lock core 41, which is connected to the lock plate 42. Rotating the lock core 41 drives the lock plate 42 to rotate, so as to drive the lock rod 5 and the extended lock portion 43 to move and close the nuclear power cabinet.

[0028] The specific working process of the utility model is as follows:

[0029] When opening or closing the nuclear power cabinet in the open / closed state, first rotate the lock core 41 on the right door panel 3 to drive the connected lock piece 42 to rotate, thereby driving the lock rod 5 on the right door panel 3 to contract. Until the lock rod 5 on the right door panel 3 retracts to the inside of the right door panel 3, the lock rod 5 no longer restricts the positional relationship between the right door panel 3 and the door frame 11. When rotating the lock core 41 on the right door panel 3, the extended lock part 43 rotates synchronously with the lock piece 42 to the inside of the right door panel 3, no longer restricting the positional relationship between the right door panel 3 and the left door panel 2. The right door panel 3 is unlocked and can be rotated around the door frame 11 to open or close the nuclear power cabinet. Then rotate the lock core 41 on the left door panel 2 to drive the connected lock piece 42 to rotate, thereby driving the lock rod 5 on the left door panel 2 to contract. Until the lock rod 5 on the left door panel 2 retracts to the inside of the left door panel 2, the lock rod 5 no longer restricts the positional relationship between the left door panel 2 and the door frame 11. The left door panel 2 is unlocked and can be rotated around the door frame 11, that is, the double-door nuclear power cabinet is completely opened. When closing the open nuclear power cabinet, just operate in the reverse direction.

[0030] It can be seen that for the above double-door nuclear power cabinet, there is no column set, making the opening of the nuclear power cabinet larger and facilitating the installation of the internal structure of the nuclear power cabinet. At the same time, lock rods 5 are provided on the left door panel 2 and the right door panel 3. Through the lock rods 5, the structural strength after the left door panel 2 and the right door panel 3 are closed is enhanced, making the connection between the left door panel 2 and the right door panel 3 and the door frame 11 more stable, and thus ensuring the sealing performance of the nuclear power cabinet.

[0031] 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 within the scope described in this specification.

[0032] The above embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on 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.
