Description

Technical Field

[0001] The utility model relates to the technical field of industrial and commercial energy storage cabinet structures, and more specifically, to a door lock structure for preventing a lock rod from deforming. In addition, the utility model also relates to an energy storage cabinet comprising the door lock structure for preventing a lock rod from deforming. Background Art

[0002] Industrial and commercial energy storage is a typical application of distributed energy storage systems on the user side. It is mostly built in an integrated cabinet. Industrial and commercial energy storage cabinets (hereinafter referred to as energy storage cabinets) are generally placed outdoors, and the protection level needs to reach IP55 (IP55 protection level means that the dustproof level is level 5 and the waterproof level is level 5. It cannot completely prevent dust from entering, but the amount of dust entering must not affect the normal operation of the equipment and must not affect safety). Among them, the cabinet door is waterproofed by forming a seal through the compression of the rubber strip, and the compression of the rubber strip is achieved by the pin of the cabinet door lock rod squeezing into the lock buckle of the cabinet body. Therefore, the key point of cabinet door waterproofing is that the door lock lock plate can push the lock rod upward so that the pin can fully enter the lock buckle. In the prior art, the installation position of the door lock is moved a certain distance, so that an additional connecting rod needs to be added between the door lock plate and the lock rod to achieve linkage. The connecting rod acts as a lever, which not only enlarges the clearance between the internal parts of the door lock, but also subjects the locking rod to torque. In addition, the design strength of the connecting rod and the locking rod is insufficient. Under the combined influence of multiple factors, the connecting rod bends and deforms, making it impossible to give the pin enough thrust, so that the pin cannot be squeezed into the lock, resulting in the cabinet door not being closed tightly, thereby leaking.

[0003] In summary, how to prevent the connecting rod and the locking rod from bending and deforming is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content
