Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, in particular to a locking device for an outdoor electrical cabinet. Background Art

[0002] An electrical cabinet is an electrical device that opens and closes, controls and protects electrical equipment during the process of power generation, transmission, distribution and energy conversion in the power system. The electrical cabinet body is made of metal, and the electrical components of the electrical cabinet are assembled inside the cabinet. After the cabinet door and the cabinet body are closed, the cabinet door is locked by a lock mechanism to prevent the external environment from causing damage to the electrical components inside the electrical cabinet.

[0003] The existing electrical cabinet locks are either electrically controlled or mechanically controlled. The electrically controlled locks are convenient for controlling the opening and closing of the cabinet door, but due to factors such as circuit damage or power on and off, the electrical cabinet door may not be opened. Especially in outdoor environments, the electrically controlled locks are more likely to be damaged. Traditional mechanical locks are not affected by power on and off, but the lock body of the existing mechanical lock is installed on the cabinet door, and the lock tongue part is plugged into the cabinet body, usually in the middle position of the side of the cabinet body. The cabinet door is plate-shaped. In outdoor environments, wind flows into the cabinet body from the cabinet door, and the cabinet body and the cabinet door are only locked at the middle position by the lock tongue. The upper and lower ends of the cabinet door are prone to wind blowing and pulling, resulting in the lock tongue being easily swung back and forth at the cabinet body when locked, which is easy to cause deformation of the lock tongue and the cabinet body, thus causing the cabinet door to be loosely closed. At the same time, the temperature difference between the outdoor and the cabinet body easily causes the cabinet door to be adsorbed on the cabinet body, which is not convenient for the cabinet door to be opened. For this reason, we propose an outdoor electrical cabinet locking device. Summary of the invention

[0041] A drying block 14 is placed inside the ventilation slot 11, which is beneficial to keeping the inside of the ventilation slot 11 dry and preventing humid air and moisture from entering the interior of the electrical cabinet.

[0042] When the cabinet door 2 is closed, the lock head 48 at the front end of the lock cylinder 42 is partially inserted into the lock hole 41. When the wind blows to the cabinet door 2, the air bag body 7 inside the cabinet door 2 is squeezed and deformed inside the ventilation groove 11, which is conducive to releasing the stress of the wind on the cabinet door and avoiding deformation of the cabinet door 2. At the same time, the cabinet door 2 is kept in close contact with the cabinet body 1 as a whole, reducing the deformation of the lock cylinder 42 and the lock hole 41 on the cabinet door 2 after a single mechanical lock is locked. When the cabinet door 2 needs to be opened, the dust cover 32 is opened and the key 6 is inserted into the keyhole 31. Because the column of the key 6 is fixedly connected with a protrusion that cooperates with the cross slot 56, when the protrusion is fully matched with the cross slot 56, the key 6 and the engaging body 51 form a whole. Then the key 6 is pushed inward, so that the engaging body 51, the rotating column 52 and the gear 53 are pushed forward. When the turning key 6 encounters resistance, the teeth of the gear 53 are fully matched with the rack 421. When the door 2 is locked, the key 6 is locked. When the key 6 is turned, the teeth of the gear 53 just come into contact with the teeth of the rack 421, until the teeth of the gear 53 fit with the rack 421. When the key 6 is turned again, the gear 53 drives the rack 421 to move, thereby pulling the lock cylinder 42 outward until the lock head 48 of the lock cylinder 42 is separated from the lock hole 41. When the lock head 48 is separated from the lock hole 41, since the upper and lower parts of the lock head 48 are both designed with V-shaped grooves 481, and the sliding ball 81 slides inside the V-shaped groove 481, the V-shaped groove 481 is designed as shown in the attached figure. Fig. 9 As shown, the sliding ball 81 can slide from the bottom of the V-shaped groove 481 to the top position, and then push the movable rod 82 upward, so that the upper curved rod 83 and the lower curved rod 83 are moved, so that the pushing ball 84 fixedly connected to the curved rod 83 squeezes the airbag body 7, squeezes out the gas inside the airbag body 7, so that the ventilation groove 11 is filled with gas, and the upper and lower parts of the cabinet door 2 are pushed outward for a certain distance, so as to facilitate the opening of the cabinet door.

[0043] By designing ventilation grooves 11 at the upper and lower parts of the cabinet body 1, and inserting an airbag body 7 fixed to the cabinet door 2 inside the ventilation grooves 11, it is beneficial to maintain a sealed contact between the cabinet door 2 and the upper and lower parts of the cabinet body 1. At the same time, when the airbag body 7 acts on the ventilation grooves 11, it is beneficial to release the stress of the cabinet door 2 being blown by the wind. The lock core 42 designed in the middle of the cabinet door 2 is connected to the lock hole 41 of the inner lock body 4. When the cabinet door 2 is opened, it is convenient to synchronously drive the provided jacking assembly 8, so that the airbag body 7 releases gas, which is beneficial to opening the cabinet door 2 from the cabinet body 1.
