Abstract

The utility model discloses a once-used lock which belongs to a lock. The utility model is mainly used for railway box cars and containers and is characterized in that three-level valve cavities are arranged inside an inner cavity of a lock, three-level barbs which match with the valve cavities are arranged on a lock handle inserted bar of a lock core, when the lock core is inserted into a lock, the three-level barbs are respectively unfolded in the three-level valve cavities, the doors of box cars or containers are tightly locked and can not be opened. The lock is a once-used lock, which can not be repaired or used repeatedly, thereby effectively preventing goods from being lost or stolen, and the protection responsibility is clear. The design is of a reasonable structure, low cost and good protective performance. The utility model is a perfect product of loss prevention, theft prevention for freight transportation.

Description

Sealing lock

Technical field

The utility model belongs to the lockset scope, particularly is used for article anti-loss mistake in box car and the container, antitheft a kind of sealing lock.

Background technology

Widely used straight-bar type blocks on existing box car and the container, and its inserted link strength ratio is less, and lock core is relatively weaker, and the recycling phenomenon is many, destructible, conveying objects are easily lost, and be stolen, often causes in the shipment process responsibility of loss of goods indeterminate.

Summary of the invention

The purpose of this utility model provides a kind of sealing lock, is made up of tapered end and lock core.Its embodiment is to leave three grades of valve pockets 2 and fore shaft 4 in the lock body 1 of described tapered end; An end is provided with three grades of hangnails 3 on the shank of the key 5 of described lock core, and corresponding with valve pocket 2, and the other end is a handle 6.

Equidistantly on described lock body 1 cylindrical vertically mill out 2-4 plane or make regular polygon.

Hangnail 3 on the described lock core is the 3-8 lobe.

The beneficial effects of the utility model are 1. the one-level bayonet socket to be increased to three grades of bayonet sockets, have improved the preventing destructing performance of sealing lock greatly.2. lock core adopts three grades of elasticity self-lockings, can only disposablely use, and once destruction, can not repair.3. scribble fluorescent material in a sealing lock numbering and a name of station place, station, be convenient to shipping handing-over at night and check.4. adopt injection molding technology once to finish, cost is low, intensity is high, the practical effect well, is anti-lost, the antitheft good product of railway transportation and containerized traffic.
