Abstract
Description
A power distribution cabinet door lock installation structure Technical Field
[0001] This utility model relates to the technical field of door lock installation structure, and in particular to a door lock installation structure for a power distribution cabinet. Background Technology
[0002] As a key component of the distribution cabinet, the door lock plays a crucial role. It not only prevents unauthorized personnel from opening the cabinet, avoiding electrical safety accidents caused by misoperation, but also effectively protects the electrical components inside from external interference and damage, such as dust and moisture intrusion, ensuring the stable operation of the power system. Therefore, a suitable installation structure for the distribution cabinet door lock needs to be designed.
[0003] Traditional power distribution cabinet door locks often employ a single protection method, which has significant shortcomings and cannot provide sufficient anti-pry protection. Installing a door lock structure that can be blocked by both a bolt and a latch, combining two different locking methods, can prevent the door from being easily pushed open to a certain extent. The latch adds an extra layer of security, effectively preventing unauthorized entry by prying, thus improving the security of the power distribution cabinet door lock and reducing security risks. Traditional power distribution cabinet door locks mostly lack a dedicated protective structure for the keyhole, leaving the keyhole directly exposed to the external environment. Moisture, dust, and debris can easily settle into the keyhole, causing the lock's performance to decline rapidly and accelerating the corrosion and damage of the lock cylinder. Summary of the Invention
[0004] (a) Technical problems to be solved
[0005] The purpose of this utility model is to provide a power distribution cabinet door lock installation structure to solve the problems mentioned in the background art, such as the single protection method, which cannot provide sufficient anti-pry protection, and the fact that the performance of the door lock will rapidly decline and accelerate the corrosion and damage of the lock cylinder due to the special protective structure for the lock hole.

[0010] As a further embodiment of this utility model, a limiting spring is fixedly connected to the back of the spring block, and the back of the limiting spring is fixedly connected to the inner side of the top of the slide bar. The limiting spring allows the spring block to move back and forth for easy adjustment.
[0011] As a further embodiment of this utility model, a pressing plate is fixedly connected to the rear end of the pressing rod. The pressing plate is slidably connected to the top of the spring block. By setting the spring block, the spring block enters the limiting groove when the protective sliding cover slides to the top, so that the protective sliding cover can be fixed and not fall.
[0012] As a further embodiment of this utility model, a connecting rod is fixedly connected to the middle of the front end of the push rod, and a button ball is fixedly connected to the top of the connecting rod. By setting the button ball, the push rod, along with the end plate, pushes the spring block back to its original position when the button ball is pressed, so that the protective sliding cover can fall back to its original position.
[0013] As a further embodiment of this utility model, adhesive strips are installed around the outer perimeter of the cabinet door, a dustproof net is installed inside the right side of the cabinet door, and a ventilation window is installed outside the dustproof net.

[0014] (III) Beneficial Effects
[0015] This utility model provides a power distribution cabinet door lock installation structure, which has the following advantages:
[0016] 1. The installation structure of this distribution cabinet door lock, through the design of the door lock mechanism, requires the external key to be inserted into the lock cylinder before use. Turning the external key causes the rear lock cylinder and stud to rotate. A bolt is installed on the outside of the middle section of the stud, allowing it to rotate upwards and stop inside the door frame. Because a pin hole is located inside the bolt, the movable pin inside the door frame slides into the pin hole when the bolt rotates upwards. This combination of bolt and pin fixing methods increases the lock's strength and avoids insufficient anti-pry protection due to a single method of protection. It achieves an organic combination of two different locking methods, preventing the cabinet door from being easily pushed open, adding extra security, improving the safety of the distribution cabinet door lock, and reducing security risks.
[0017] 2. The installation structure of this distribution cabinet door lock, through the setting of the protective mechanism, allows the protective sliding cover to slide upwards to expose the internal lock head when the device is to be used. Sliding strips are installed on the inner sides of both sides of the protective sliding cover, and limit springs and spring blocks are installed on the top of the sliding strips. When the protective sliding cover slides to the top, the spring blocks will enter the limit groove under the action of the limit springs, thereby fixing the protective sliding cover. After unlocking, pressing the button ball pushes the button rod and the button plate. The button plate then pushes the spring block out of the limit groove and returns it to its original position, allowing the protective sliding cover to fall down and cover the lock head again. This achieves the function of sliding to cover the lock head, protecting the lock head, and preventing the lock hole from being directly exposed to the external environment. Moisture, dust, and debris can easily settle into the lock hole, causing the door lock's performance to decline rapidly and accelerating the corrosion and damage of the lock cylinder.
