The working principle of the invention is as follows:
when the cabinet door 300 is locked, the cabinet door 300 is close to the cabinet body 400, the insert 111 extends into the through cavity N3 of the lock catch seat 200, after the inclined surface of the fixture block 120 contacts the side wall of the through cavity N3, the fixture block 120 can move towards the movable opening N2 to compress the spring 123 until the fixture block 120 is hidden in the lock body 110, the movement is continued until the fixture block 120 moves to the lock groove N1, the fixture block 120 is reset to extend into the lock groove N1 under the action of the spring 123 to realize lock catch, and at this time, the cabinet door 300 cannot be opened outwards; during locking, the cabinet door 300 just contacts with the cabinet body 400, and at the moment, the cabinet door 300 cannot move inwards continuously;
during unlocking, the special unlocking tool 500 extends into the third sliding cavity N5-3 until the key block 503 of the unlocking cylinder 501 extends into the key groove N6 of the stopping part 133-2, meanwhile, the conical end part of the stopping part 133-2 extends into the conical cavity 502 to push the special unlocking tool 500, the driving part 133 pushes the first rack 131 to move linearly, the second rack 124 is driven to move reversely under the action of the gear 132, and at the moment, the operating rod 121 pulls the clamping blocks 120 on the two sides to compress the spring 123 into the movable opening N2 through the connecting rod 122; the locking mechanism continues to move until the stopping portion 133-2 reaches the second sliding cavity N5-2, the special unlocking tool 500 is rotated by the handle 504, the whole driving member 133 is driven to rotate by the key block 503, the stopping portion 133-2 is connected into the second sliding cavity N5-2 in a threaded mode until the locking member cannot rotate continuously, and at the moment, the clamping block 120 is hidden into the lock body 110, so that unlocking is achieved.
Because the driving element 133 of the present invention is hidden in the sliding cavity N5, the driving element 133 cannot be directly pushed by a common tool, and further, the end of the driving element 133 is tapered, which increases the difficulty of pushing the driving element 133 by a common tool and also increases the difficulty of rotating the driving element 133; even if the driving element 133 can be pushed to move, the stopping part 133-2 is in contact with the mounting plate 113-3 at the farthest distance for pushing the driving element 133 to move, and the stopping part 133-2 cannot enter the second sliding cavity N5-2 because the driving element 133 cannot be rotated, and the clamping block 120 is not completely hidden in the lock body 110 at this time, the purpose of unlocking cannot be achieved.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
