[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 A door locking mechanism for a power cabinet, comprising a cabinet body 1 and a cabinet door 2 rotatably mounted on the cabinet body 1. Two locking plates 3 are fixedly mounted on the side wall of the cabinet body 1, and two fixing blocks 6 are fixedly mounted on the inner side of the cabinet door 2. Each fixing block 6 has a sliding rod 5, and each locking plate 3 has a locking hole 4 adapted to the sliding rod 5. A handle 8 is rotatably mounted on the side of the cabinet door 2 away from the cabinet body 1, and the handle 8 contains a driving mechanism for moving the sliding rod 5. The handle 8 is fixedly mounted on the side of the cabinet door 2, the locking plates 3 are symmetrically fixed on the upper and lower sides of the side wall of the cabinet body 1, the handle 8 is positioned in the middle of the side of the cabinet door 2, and the two fixing blocks 6 are symmetrically fixed on the inner wall of the cabinet door 2. On both the top and bottom sides, when the cabinet door 2 is closed, the two fixing blocks 6 are positioned between the two locking plates 3. In use, pull the handle 8 outwards. The handle 8, through the drive mechanism, pulls the two moving rods 5 towards the middle position, and then closes the cabinet door 2, which abuts against the side wall of the cabinet body 1. Then, rotate the handle 8 towards the cabinet door 2 so that the handle 8 fits against the cabinet door 2. At this time, the drive mechanism moves the two moving rods 5 towards the locking plate 3 and inserts them into the corresponding locking holes 4, thereby locking the cabinet door 2 at the position of the two locking plates 3. The handle 8 in the middle of the cabinet door 2 can control the locking position of the top and bottom sides of the cabinet door 2, preventing large warping of the top and bottom sides of the cabinet door 2 and ensuring the function of the cabinet door 2.

[0018] Specifically, a mounting plate 7 is fixedly installed on the cabinet door 2, and a support plate 10 is fixedly installed on the mounting plate 7. The support plate 10 is rotatably connected to the handle 8. The cabinet door 2 has a through groove 9 at the position of the mounting plate 7. The through groove 9 allows the drive mechanism to move. The support plate 10 can support the handle 8. When the handle 8 is pulled, the handle 8 rotates around the axis position at the end of the support rod 15.

[0019] Specifically, the drive mechanism includes a push rod 11 rotatably disposed inside the handle 8. A rotating block 13 is fixedly disposed at the end of the push rod 11 away from the handle 8. A connecting frame 12 is rotatably disposed on the rotating block 13. A movable groove 20 is provided on the mounting plate 7. When the handle 8 is rotated, the handle 8 pulls the push rod 11 to move away from the cabinet door 2. Since the handle 8 rotates around the end of the support rod 15, the push rod 11 will swing when the handle 8 pulls the push rod 11 to move. The movable groove 20 provides space for the push rod 11 to swing. When the push rod 11 moves, it will drive the rotating block 13 and the connecting frame 12 to move, thereby pushing the two moving rods 5 to move.

[0020] Specifically, each movable rod 5 has a top rod 17 rotatably mounted on the end near the handle 8, and the end of each top rod 17 away from the movable rod 5 is rotatably connected to the connecting frame 12; the rotating block 13 is located in the middle of the rotatable connection between the two top rods 17 and the connecting frame 12. When the handle 8 is pulled, the handle 8 drives the push rod 11 and the connecting frame 12 to move away from the cabinet 1, thereby pulling the ends of the two top rods 17 away from the movable rod 5 away from the cabinet 1, and then pulling the two movable rods 5 towards the middle, so that the cabinet door 2 and the cabinet 1 can be abutted together, and each movable rod 5 can be moved out of the corresponding locking hole 4, thereby unlocking the cabinet door 2 and the cabinet 1.

[0021] Specifically, a limit rod 14 is fixedly installed inside the handle 8, and a support rod 15 is fixedly installed on the mounting plate 7. An elastic clamp plate 16 adapted to the limit rod 14 is fixedly installed on the support rod 15. The elastic clamp plate 16 is a metal arc plate with a certain elasticity. When the two moving rods 5 are inserted into the corresponding locking holes 4, the handle 8 is completely attached to the cabinet door 2. At this time, the limit rod 14 is inserted into the arc-shaped elastic clamp plate 16. The elastic clamp plate 16 limits the limit rod 14 to a certain extent, so that the handle 8 will not easily rotate. During daily maintenance and repair, the cabinet door 2 needs to be opened and closed frequently. At this time, it is not suitable to completely lock the cabinet door 2. The cooperation between the elastic clamp plate 16 and the limit rod 14 prevents the cabinet door 2 from being accidentally opened during maintenance and repair.

[0022] Specifically, an extension plate 18 is fixedly installed at the tail of the handle 8, and a bolt 19 is rotatably installed on the extension plate 18. A threaded groove adapted to the bolt 19 is opened on the mounting plate 7. The extension plate 18 is fixedly installed on the lower side of the handle 8. When the cabinet door 2 is closed and each moving rod 5 is inserted into the corresponding locking hole 4, in daily use where the cabinet door 2 does not need to be opened and closed frequently, the bolt 19 is rotated to tighten the bolt 19 into the threaded groove on the mounting plate 7, thereby fixing the handle 8 to the mounting plate 7. At this time, the handle 8 can be prevented from rotating, further ensuring the locking state between the cabinet door 2 and the cabinet body 1, and enhancing the protection of the cabinet door 2.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
