Description

Technical Field

[0001] The present application relates to the technical field of switch cabinets, and in particular to a lock body structure for a high-voltage or low-voltage switch cabinet and the switch cabinet thereof. Background Art

[0002] The existing high / low voltage switch cabinet door locks use a separate lock tongue to buckle the cabinet frame column and the handle to connect the connecting rod, and the handle is rotated to drive the connecting rod to lock the upper and lower crossbeams of the cabinet frame. When a separate lock tongue is used to buckle the cabinet frame column, when the cabinet door height exceeds 0.6m and the length exceeds 0.5m, multiple lock body structures are required, which occupy the space inside the cabinet, are difficult to install, and are difficult to open and close after installation. When the handle is used to connect the connecting rod, due to excessive local force on the connecting rod and unbalanced force, the connecting rod will deform after long-term use, which can easily lead to the situation that it cannot be locked. At this time, the lock body needs to be removed and replaced separately, which affects the normal use of the switch cabinet. In addition, the lock body structure is difficult to replace, which often leads to the cabinet being abandoned due to ineffective locking.

[0003] The information disclosed in the background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to ordinary technicians in this field.

[0034] See also Figures 1 to 5 The present application provides a lock structure for a high-voltage or low-voltage switchgear cabinet. The high-voltage or low-voltage switchgear cabinet comprises a cabinet body 1 and a cabinet door 3. The cabinet door 3 covers an opening formed in a side wall of the cabinet body 1. A flange 31 is provided on the periphery of the cabinet door 3, extending toward the cabinet body 1 and perpendicular to the periphery of the cabinet door 3. The lock structure is accommodated within the flange 31, achieving an aesthetically pleasing effect while concealing the lock structure.

[0035] The handle 21, lock base 211, and lock member 212 are mounted on the outer wall of the cabinet door 3. One end of the handle 21 is hinged to the lock base 211 and pivots about the hinge. The lock member 212 is mounted within a through-hole provided at the other end of the handle 21. The lock member 212 comprises a rotatable locking assembly and a tongue 219. The tongue 219 is connected to one end of the locking assembly, while the other end of the locking assembly is received within the through-hole of the handle 21.

[0036] A tab 225 is provided at the lower end of the lock base 211. This tab 225 is spaced from the cabinet door 3, leaving a gap to accommodate a tongue 219. The tongue 219 rotates with the rotation of the locking assembly. After the locking assembly rotates, when the tab 219 is in the first position, it is accommodated between the cabinet door 3 and the tab 225 at the bottom of the lock base 211, restricting the upward movement of the lower end of the handle 21. After the locking assembly rotates, when the tab 219 is in the second position, the tab 219 rotates out of the gap between the tab 225 and the cabinet door 3 and forms a 90° angle with the first position. At this point, the upward movement restriction on the lower end of the handle 21 is released, allowing the cabinet door 3 to be opened. The locking assembly is a commercially available locking structure that allows a key to be inserted at one end and rotates at the other end, and will not be described in detail here.
