Abstract

A magnetic theftproof lock is characterized in that the utility model comprises a lock body which is provided inside with a lock pin case, with a lock pin arranged in the lock pin case and spring holes opened in the lock pin case. Spring grooves are arranged on the lock pin wall, magnetic springs are arranged between the spring holes and the spring grooves, and a key groove arranged in the lock pin is engaged with the key. The key is provided with a magnetic steel sheet which is corresponding to the magnetic spring, the lock pin drives a latch mechanism which is engaged with a lock bolt. The spring grooves arranged in the lock pin wall are blind holes, and the key utilizes magnetic property to attract instead of directly contact with the magnetic springs in the lock pin and the lock pin case, so the lock can not be prized by iron sheet and other foreign bodies (master key), with great theftproof performance. Since the magnetic springs arranged in the lock pin and the lock pin case have great capacity, and the magnetic springs can be mutually attractted to arrange (S, N pole or N, S pole), or repulsion arranged (N, N pole or S, S pole), the separating rate is very low.

Description

Magnetic anti-theft lock

Technical field

The utility model relates to lockset, particularly relates to magnetic anti-theft lock, mainly is applicable to various locks, also can be used for padlock, door lock etc.

Background technology

The kind of locks such as existing bicycle, motorcycle is a lot, for example crab claw lock, steel wire lock, cylinder lock etc., and the shortcoming of its crab claw lock and cylinder lock existence has: the one, easily by steel disc tamper tools such as (key shapes); The 2nd, the mutual opening rate height.Steel wire lock is cut off again easily, and is dangerous equally.Another kind of type is a coded lock, but cipher lock can be felt by light, the double infection of veteran when rotating again or sound is decoded, opened.Therefore, existing lockset (referring in particular to existing bicycle lock etc.) ubiquity shortcomings such as theftproof performance difference.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, and contactless pellet shot from a slingshot in a kind of lock core is provided, and can't pry open with foreign matter (master key), avoid again unblanking by force, and the extremely low magnetic anti-theft lock of mutual opening rate.

The technical scheme of the utility model magnetic anti-theft lock is: it is characterized in that having a lock body, lock core shell is arranged in the lock body, lock core is installed in the lock core shell, in lock core shell, be shaped on the pellet shot from a slingshot hole, on the lock core wall, be shaped on bullet groove, in pellet shot from a slingshot hole and the bullet groove magnetic bullet is installed, is shaped on key in lock core, key matches with key, magnetic links is installed in the key, magnetic links is corresponding with magnetic bullet, and lock core drives latching device, and latching device matches with lock bolt.

Magnetic anti-theft lock of the present utility model, bullet groove on the lock core wall is a blind hole, and the key of unblanking does not directly contact with magnetic bullet in the lock core shell with lock core, but utilizes magnetic to inhale mutually, so can not pry open with foreign matters such as iron plate (master key), theftproof performance is good.Because the magnetic bullet capacity arranged in lock core and lock core shell is big, but and magnetic bullet phase suction row (S, the N utmost point or N, the S utmost point) or the arrangement that repels each other (N, the N utmost point or S, the S utmost point), so mutual opening rate is extremely low.

Magnetic anti-theft lock of the present utility model, its concrete technical scheme of described latching device can have multiple, and one of example is that lock core promotes latch hook through push rod, and latch hook matches with lock bolt, and latch hook contacts with lock body through screw and spring.The key that insertion matches, all pellets shot from a slingshot enter lock core shell, and key drives lock core and promotes latch hook through push rod, and latch hook breaks away from lock bolt, and lock is opened.Under its lock core back-moving spring is arranged, push bolt spring and spring compressor are installed in the lock body.The bottom of its lock core is shaped on the push rod jacking block, and the push rod jacking block contacts with push rod, and high convex edge of rising is arranged at the edge of jacking block, embraces the head of push rod, prevents that foreign matter from inserting push rod head promotion push rod and unblanking.The head of its lock bolt is shaped on groove, and groove matches with latch hook.The bottom of its lock core studs with easy part, and easily part contacts with key head, when the robber inserts key by force with iron plate, uses hammer ironwork sheet, and iron plate can smash easy part, but lock core and lock core shell still can not be opened.Its easy part is that plastics or aluminium or materials such as copper material or kirsite are made.Its described latch hook outer wall is made circular arc, but because lock body rounding cylindricality also has lock housing outside lock body.Bullet groove in its lock core becomes symmetry with both sides, pellet shot from a slingshot hole in the lock core shell, every side is a hole, 1 hole-50, and 1-50 magnetic links is installed in the key of unblanking.A magnetic bullet is installed in its each bullet groove and each pellet shot from a slingshot hole.

The specific embodiment

The utility model relates to magnetic anti-theft lock, as shown in Figure 1, its major technology has been characterised in that a lock body 1, lock housing 18 is arranged outside the lock body 1, but in actual product, according to the purposes difference of lock, the shape of lock housing is also different, lock core shell 2 is arranged in the lock body 1, lock core 7 is installed in the lock core shell, in lock core shell 2, be shaped on pellet shot from a slingshot hole 3, on the lock core wall, be shaped on bullet groove 8, magnetic bullet 4 is installed in pellet shot from a slingshot hole 3 and the bullet groove 8, is shaped on key 19 in lock core, key matches with key 5, magnetic links 6 is installed in the key, magnetic links 6 is corresponding with magnetic bullet 4, and lock core drives latching device, and latching device matches with lock bolt.But utilize the characteristics of magnetic bullet phase suction row (S, the N utmost point or N, the S utmost point) or the arrangement that repels each other (N, the N utmost point or S, the S utmost point), the magnetic bullet capacity is big, and mutual opening rate is extremely low, and theftproof performance is good.Its described latching device is that lock core 7 promotes latch hook 15 through push rod 20, and latch hook 15 matches with lock bolt 16, and latch hook 15 contacts with lock body 1 through screw 21 and spring 17, and the key of unblanking drives lock core and promotes latch hook through push rod, and latch hook breaks away from lock bolt, and lock is opened.Its lock core has back-moving spring 11 7 times, and push bolt spring 12 and spring compressor 13 are installed in the lock body 1.As Fig. 2, shown in Figure 3, the bottom of its lock core 7 is shaped on push rod jacking block 22, and the push rod jacking block contacts with push rod 20, high convex edge 23 of rising is arranged at the edge of jacking block, the convex edge is higher than jacking block, and the head of push rod is embraced, and can prevent that the head promotion push rod of foreign matter insertion push rod from unblanking.The head of its lock bolt 16 is shaped on groove 14, and groove 14 matches with latch hook 15.The bottom of its lock core 7 studs with easy part 9, and easily part 9 contacts with key 5 heads, and when being subjected to heavy impact, easily part fragmentation or separate with lock core and to enter caulking groove easily makes in lock core and the lock core shell pellet shot from a slingshot not be damaged.Its easy part 9 is that plastics or aluminium or materials such as copper material or kirsite are made.Its described latch hook 15 outer walls are made circular arc, but because lock body rounding cylindricality, and general lock housing 18 also all is circular, as shown in Figure 6.Bullet groove 8 in its lock core 7 becomes symmetry with 3 both sides, pellet shot from a slingshot hole in the lock core shell 2, every side is a hole, 1 hole-50,1-50 magnetic links 6 is installed, as Fig. 2, Fig. 3 and Fig. 4 and shown in Figure 5 in the key 5 of unblanking.A magnetic bullet 4 is installed in its each bullet groove 8 and each pellet shot from a slingshot hole 3.
