Abstract

The utility model relates to a lock which comprises a lock body, a U-shaped lock post, a magnet clamping post, a locking block and a key, wherein the U-shaped lock post is arranged in the lock body by a spring of the lock post, and the magnet clamping post with a return spring is arranged between both sides of a lock hole and a clamping groove of the U-shaped lock post. The bottom part of the lock hole is also provided with the locking block which is connected with the spring of the locking block at the rear end. The key corresponding to the magnet clamping post is inlaid with a magnet. The utility model has the characteristics of simple structure, convenient use, low cost, theft protection, etc. The arrangement of a plurality of arbitrary positions and the arbitrary disposition of the polarity direction of the magnet clamping post in the lock cause the lock to have a good theft protection effect.

Description

A kind of lock

1, technical field

The utility model relates to a kind of lockset, specifically a kind of lock that utilizes magnet to control switching.

2, background technology

The lock of controlling switching with magnet is a lot, but all exist complex structure, use inconvenient, anti-theft effect is poor, make shortcomings such as difficulty, cost height, for example, the Chinese patent patent No. is ZL95233483.6, notice of authorization number is made up of lock body, lock core, lock tube and the key that inserts in the lock tube for described this lock of Anti-theft magnetic lock of CN2242940Y, characteristics are to utilize the magnetic force of magnetic marble to replace spring, utilize the directed intensive magnetic circuit of magnetic conductivity key, but operate more complicated in use, theftproof performance is not fine in addition, is decoded by the people easily.

3, summary of the invention

Technical assignment of the present utility model provides a kind of good anti-theft effect and utilizes magnet to control the lock of switching.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of lock, comprise lock body, U-shaped lock, magnet card post, sealing piece, key, the U-shaped lock is arranged in the lock body by the lock spring, be provided with the magnet card post of band return spring between lockhole both sides in lock body and the U-shaped lock draw-in groove, the lockhole bottom also is provided with the sealing piece, the sealing piece is connected with the sealing piece spring of rear end, and corresponding on the key magnet Ka Zhuchu is inlaid with magnet.

The polarity of the outside polarity of the magnet magnet card post rear end corresponding with it is opposite on the key.

A kind of lock of the present utility model is compared with prior art, have simple in structure, easy to use, characteristics such as cost is low, theftproof performance good, long service life, in this lock the setting of the optional position, many places of magnet card post with and any arrangement of polar orientation, make that this lock anti-theft effect is splendid.Thereby, have good value for applications.

4, description of drawings

Accompanying drawing 1 is a kind of main TV structure schematic diagram of lock.

5, the specific embodiment

With reference to explaining below 1 pair of a kind of lock work of the present utility model of Figure of description.

A kind of lock of the present utility model, comprise lock body 1, U-shaped lock 2, magnet card post 4, sealing piece 8, key 9, U-shaped lock 2 is arranged in the lock body 1 by lock spring 6, be provided with the magnet card post 4 of band return spring 3 between lockhole both sides in lock body 1 and U-shaped lock 2 draw-in grooves, the lockhole bottom also is provided with sealing piece 8, sealing piece 8 is connected with the sealing piece spring 7 of rear end, and corresponding magnet card post 4 places are inlaid with magnet 5 on the key 9.

The polarity of the outside polarity of magnet 5 magnet card post 4 rear ends corresponding with it is opposite on the key 9.
