Special-purpose machinery theft-proof lock for cabinet

Abstract

The invention discloses a box cabinet special-purpose mechanical anti-theft lock, and comprises a lock body, a lock column and a lock head, the lock body is an integration pouring cast steel lock body, the lock column is an upper lock column (6) and a lower lick column (10) braced out by a spring (21) and a spring (22), the lock column is respectively matched in an upper lock column hole and a lower lock column hole of the cast steel lock body in a horizontal way, the lock head adopts a marble lock head (8) with an axial direction rotating type marble hole, a device that simultaneously toggles the upper lock column (6) and the lower lick column (10) from the same direction, and enables the upper lock column (6) and the lower lick column (10) to be completely retracted in the upper lock column and the lower lock column of the cast steel lock body (7) is arranged at the tail end of the marble lock head (8); a device that automatically positions the upper lock column (6) and the lower lick column (10) and releases the position when the upper lock column (6) and the lower lick column (10) is completely retracted in the upper lock column and the lower lock column of the cast steel lock body (7) is arranged in the cast steel lock body (7) and the marble lock head (8). The whole lock body structure of the lock is stable, the structure is simple, the manufacturer cost is lower, and the key can not be matched, and the anti-theft effect is good.

Description

technical field [0001] The invention relates to an anti-theft lock, in particular to a special mechanical anti-theft lock for a cabinet. Background technique [0002] The cabinet anti-theft lock of prior art generally adopts the supporting structure of mechanical lock and electronic lock or combination lock. And the special-purpose mechanical antitheft lock of cabinet of prior art is of a great variety, and structure is different. But as far as the applicant knows, the special mechanical anti-theft lock for cabinets in the prior art still has the following deficiencies: 1. The lock parts are generally all mounted on the inner surface of the steel plate, especially the lock cylinder is generally shorter and only passes through one end of the steel plate The right-angle curling of the right-angled edge and the lock post hole that enters the cabinet frame seem thinner in its structure, and its positioning strength is not enough. If it is destroyed by violence, it may still be ...

And the special mechanical anti-theft lock of cabinet of prior art is of a great variety, and structure is different

But as far as the applicant knows, the special mechanical anti-theft lock for cabinets in the prior art still has the following deficiencies: 1. The lock parts are generally all mounted on the inner surface of the steel plate, especially the lock cylinder is generally shorter and only passes through one end of the steel plate The right-angled curling edge of the box enters the lock post hole of the cabinet frame, its structure is relatively thin, and the positioning strength is not enough. If it is destroyed by violence, it may still be opened, and its anti-theft effect and safety are still not ideal.

2. Its structure is generally still relatively complex, the production process is cumbersome, and the manufacturing cost is relatively high

3. Its lock head and the matching keys are still S-shaped, cross-shaped, plum-shaped, half-moon-shaped and other common structures in the market. They still cannot prevent the preparation of keys by personnel other than the manufacturer. The safety hazard of imitation matching and unlocking the quilt cover is also unsatisfactory in terms of anti-theft effect and safety
