Description

Magnetic lock and its key

The utility model relates to a kind of lockset and key thereof, specifically a kind of magnetic padlock and key thereof.

At present, popular lock has mechanical lock, electronic lock two big classes on the market, and mechanical lock divides cylinder lock and combination lock again.This class lock or can use so-called unlocked by universal key perhaps can be opened with feeling, as is used in outdoor Chang Yin and gets rusty and can't open; Electronic lock is owing to qualitative factors such as electronic components, to the phenomenon that opens by mistake or do not open is often taken place.

The purpose of this utility model provides a kind of magnetic padlock and key thereof.

Technical solution of the present utility model is to improve design on the basis of original mechanical lock, mainly be that billiards structure with lock core makes the magnetic rod structure into, promptly corresponding design has magnetic post hole on movable piece, dynamic resistance part and the lock body outer wall of lock core, and mobilizable magnetic post is housed in the hole.This magnetic post is under the magneticaction of magnetic padlock key, or move vertically, when all magnetic posts all move in the movable piece or in the dynamic resistance part, lock core is promptly rotatable, thereby realize the unlatching of lock, above-described magnetic post adopts current magnetic energy product the highest, and coercivity is the strongest, is known as the NdFeB material of " magnetic king " and makes.

Owing to adopted above-mentioned solution, the appearance of a kind of magnetic padlock and key thereof becomes possibility.And this magnetic padlock strong security has prevented to open by mistake or the phenomenon of not opening takes place, and has antirust effect.Can change lock core structure comparatively easily by user's requirement.

Accompanying drawing 1 has been described magnetic padlock lock core structure principle, and movable piece (1) can be realized the unlatching of lock with key one starting under associated key effect; Lock body outer wall (2) is made by non-magnet material; Dynamic resistance part (3) when used key not to the time, match with magnetic post (4), can stop movable piece (1) with key motion, the lock of then not opening.Its magnetic post (4) has three types.Fig. 1 top a kind of because of its left side has small iron plate (5) to attract mutually with the magnetic post, make the magnetic post moving left, and under usual condition, it is parked between movable piece (1) and the dynamic resistance part (3), plays a part the obstruction movable piece to move; Put the heteropole of key (8) magnetic post (9) on the key towards magnetic post (4) as be adjacent to lock outer wall (2) on its right side, then because of being separated with non-magnet material (6) between magnetic post (4) and the small iron plate (5), so magnetic post (9) can be attracted in the hole of movable piece (1), and no longer hinder the motion of movable piece (1) to magnetic post (4).This magnetic post claims the normally closed magnetic post that draws away, or abbreviation draws away the magnetic post.

Adorn small iron plate (5) equally on the right side of Fig. 1 middle part magnetic post (4) and attract mutually, when key (8) is not attached to lock outer wall (2), make magnetic post (4) be parked in the motion that hinders movable piece (1) between movable piece (1) and the dynamic resistance part (3) with magnetic post (4).As put key (8) on its right, the magnetic post (10) in the key repels with it mutually, and then magnetic post (4) can be pulled in the hole of dynamic resistance part (3), and no longer hinders the motion of movable piece (1).This magnetic post is called as the normally closed magnetic post of scolding out, or is called for short and scolds out the magnetic post.

A kind of magnetic post (4) in Fig. 1 bottom is because of being parked in the centre that movable piece (1) is gone up the hole with the thin iron cylinder effect on every side of hole, place, so do not hinder the relative motion of movable piece (1) and dynamic resistance part (3).If the right side that aligns this magnetic post is equipped with the magnetic post on the key, no matter then with (4) coupling of magnetic post or repel each other, magnetic post (4) is moving will to be parked in movable piece (1) and to lock between outer wall (2) or movable piece (1) and the dynamic resistance part (3), and makes (1) inactive.This magnetic post is known as often to start and closes the magnetic post, or is called for short the moving magnetic post that closes.But,, also can not design this moving magnetic post that closes so that key magnetic force penetrates because the outer wall (2) of lock is thin as far as possible.

Fig. 2-Fig. 3 has described an embodiment of the present utility model, promptly utilizes above-mentioned magnetic post to make sealed padlock.Be lock core (12) as shown in Figure 3, rotating disk (20) is a movable piece, chuck (24) is the dynamic resistance part, go up branch two circle designs at rotating disk (20) and 15 magnetic post holes are arranged, 10 holes, outer ring, 5 holes of inner ring, wherein 1～2 is movingly closed magnetic post (22) and is made into outside the through hole for installing, other 13～14 are blind hole, and its degree of depth is greater than the magnetic column length, to hold magnetic post (23); The last corresponding branch two circle designs of chuck (24) have 15 magnetic post holes, are 10 of outer rings equally, 5 of inner rings.Wherein 13～14 are through hole, and draw away magnetic post (23) or scold out magnetic post (21) with installation, the length in hole, i.e. chuck thickness, it should equal small iron plate thickness and add non-magnet material thickness one of plus thirty magnetic column length again; And 1～2 be blind hole, and its degree of depth equals 1/2nd moving magnetic post thickness that close.Also need corresponding going up at the lock outer wall (27) of being close to rotating disk to design 1～2 blind hole simultaneously, its degree of depth equals 1/2nd magnetic column lengths.Its rotating disk and chuck are close on the lock outer wall (27) by lock core outer cover (26).The rotating shaft (25) of center of turntable dress.The end that its Shen goes out the lock core outer cover is provided with turning handle (13).Opening the round nest that is equivalent to the rotating disk size, be as the criterion can put into key piece (28) by on the outer wall of lock core one side.As shown in Figure 2, the end of turning handle (13) is linked up by link rod (19) and dead bolt (15), design a spring leaf (14), under the effect of spring force, make dead bolt (15) often block latch hook (16), have only after key works, when rotating turning handle (13), dead bolt (15) is just drawn back by link rod and unblanks.For water proof and dust proof, keep the drying and the cleaning of the built-in end of latch hook, at the inlet position of lock body (11) dress sealing ring (17).Magnetic post (18) is housed in the end of latch hook.

Fig. 4 and Fig. 5 have described and the supporting key of above-mentioned padlock.This key piece is a plastics circular slab (29), in circle, divide inside and outside two circles to be furnished with 15 small magnetic rod holes (32), 10 holes, outer ring, 5 holes of inner ring, all requirement is corresponding with the magnetic post hole of lock core rotating disk (20), establishes irony base plate (31) in the one side of key piece.For easy to carry, establish and hang head, and the hanging hole of holding funeral rites (30).

Utilize this magnetic padlock lock core structure principle also to can be made into door lock, drawer-lock etc.
