Description

The magnetic force lock

The magnetic force lock relates to a kind of lock that uses permanent magnets as pellet shot from a slingshot.

Pellet shot from a slingshot of the prior art, its pellet shot from a slingshot is locked lock by the elastic force of spring; When opening by on the key with the lock in the suitable pellet shot from a slingshot that makes of pellet shot from a slingshot size no longer block lock core, through the rotation lock is opened.The utility model is to make the pellet shot from a slingshot in lock body or the lock core block lock core by gravity, makes lock be in locking states, when opening, is in the pellet shot from a slingshot of locking state owing to be permanent magnet material, and also there is a permanent magnet position of corresponding each pellet shot from a slingshot and be installed on the key; In case after key reeve lockhole owing to the characteristic that the magnetic material same sex is inhaled mutually or there is a natural attraction between the sexes, made the pellet shot from a slingshot displacement of blocking lock core, screw key can be opened.The utility model is that a kind of brand-new technology is created.

The purpose of this utility model is, a kind of lock that uses permanent magnet material as pellet shot from a slingshot is provided, and makes to lock pick-proof afterwards, has very strong safety.

The technical solution of the utility model is as follows: (narration in conjunction with the accompanying drawings).

The locking state pellet shot from a slingshot is by action of gravity pellet shot from a slingshot to be stuck lock core or lock body when the pellet shot from a slingshot hole in the lock body is arranged in " V " font; At least arranging upwards that in the footpath of circumference a pellet shot from a slingshot hole is arranged when making lock, is two pellet shot from a slingshot holes of arranged radially when becoming " V " font such as Fig. 2, can also arrange more so that 100; " V " font can be arranged in " V " font pellet shot from a slingshot hole, equally also can require to be aligned to 100 according to lock; That is to say that the pellet shot from a slingshot hole can make arbitrarily along the circumference of lock core, quantity can be accomplished 200.The arrangement of pellet shot from a slingshot hole to only arranging 3 in the drawings, also can be arranged 100 along lock core shaft as required.Magnetic bullet 3 is housed in the pellet shot from a slingshot hole of lock body 4 is contained in 3 holes magnetic bullet 3 respectively and can does cylinder, triangular prism, bullet-headed, rectangular cylinder shape, can also make split type i.e. 1-10 pellet shot from a slingshot of dress in a hole.When manufacturing key, design the position of the permanent magnet 6 of key at the polarity of each locational pellet shot from a slingshot according to the arranging situation in pellet shot from a slingshot hole.After key 1 inserted keyhole, permanent magnet of installing on location pellet shot from a slingshot 7 location and feasible spoon body 6 and the permanent magnet pellet shot from a slingshot 3 in the one one corresponding pellet shot from a slingshot hole no longer blocked lock core 2 on lock body 4 as shown in Figure 1 and Figure 2, and screw key 1 can be opened lock.

Of the present utility modelly good outer be: 1, pick-proof and anti-theft, because of cannot see pellet shot from a slingshot in the lockhole, lock is in case pin and does not have key to be difficult to open, and its structure promptly has very strong pick-proof, password.2, can be used for any lock, technology has the universality characteristics, can be used for the many-sides such as door of automobile, motorcycle, national treasury, safety cabinet, industrial civil building.

Description of drawings: Fig. 1 is that the utility model is always schemed; Wherein: the key that 1, permanent magnet 6 is housed; 2, rotatable or unblank or the lock core of locking states; 3, magnetic bullet; 4, lock body; 5, jump ring; 6, key permanent magnet; 7, location pellet shot from a slingshot and spring; Fig. 2 is the left view of accompanying drawing 1; Fig. 3 is the part drawing of lock core 2; Fig. 4 is the left view of Fig. 3.

Embodiment: key select for use copper, aluminium or stainless steel do a spoon body permanent magnet 6 select for use magnet steel to press-fit (interference fit) or with thread connection on the spoon body, and with the contraposition one by one of corresponding pellet shot from a slingshot hole.Design various tapered ends (or dead bolt) according to purposes by prior art and link with lock core, lock core 2 is selected copper, aluminium or stainless steel for use.Magnetic bullet 3 is selected magnet steel (also available other permanent-magnet material) for use.Lock body 4 is selected copper, aluminium or stainless steel for use.Jump ring 5 selects for use spring steel location pellet shot from a slingshot 7 to select copper material for use, spring selection standard spare.Use general machining technique, each part among Fig. 1 is surveyed and drawn into part drawing (as Fig. 3, Fig. 4), can process the utility model.

Claims (3)

1, the magnetic force lock comprises key (1), lock core (2), pellet shot from a slingshot (3), lock body (4), and it is characterized in that: permanent magnet (6) is housed on the key (1), and pellet shot from a slingshot (3) is made by permanent-magnet materials, and permanent magnet (6) manufactures and designs with pellet shot from a slingshot (3) implementation contraposition.
