Abstract

The invention provides and a kind ofly can prevent foreign matter or split off the various common locks that key is blocked lockhole.It adopts in the lock body and is drilled with a deep hole, put a joint spring in the hole, the spring top is gone up with antifouling key bottom and is connected, and antifouling key top is vertically inserted in the lock core keyhole, as unblank key or foreign material are when clogging in the lockhole, and the elastic force of spring can eject it outside lock body automatically under antifouling key was lodged.The present invention also can be fit to all kinds of key operated safety cabinets, and technology is simple and easy to system.

Description

Clogging-resistant lock

The present invention relates to various common locks, particularly a kind of energy will split off key or foreign material eject the outer automatic clogging-resistant lock of lock body.

Regular meeting runs into the situation that the key of unblanking splits off in lockhole or artificially stops up lockhole with foreign material during present various common lock; to such an extent as to residual disconnected part or foreign material can't take out; have to destroy lock body at last and just can deal with problems, this has caused trouble and waste on the very big manpower and materials.

Task of the present invention is will provide a kind of foreign material or residual disconnected key can be ejected the outer clogging-resistant lock of lock body automatically.

Task of the present invention is finished like this: a garden shape deep hole is bored at the lock body place in various common lock lock cores, and this hole must not penetrate lock body, and should be less than lock core diameter and straight-through with its keyhole.One joint spring more springy is housed in the hole, one end of spring is connected with the bottom of antifouling key, (antifouling key is made with stainless steel or non-ferrous metal in the keyhole on the top insertion lock core of antifouling key, the bottom is that cylindricality top, garden is for flat or pointed, when adopting flat shape, the head of its key of unblanking also need make flat shape into, just can avoid stopping of pellet shot from a slingshot) like this because antifouling key plays barrier effect in lock core, splitting off key or foreign material will be ejected outside the lockhole automatically.

Advantage of the present invention is that decapacitation ejects foreign material or residual disconnected key outside the lockhole automatically, and it is outer and need not to dial outward with strength with hand also can to make the key of unblanking deviate from lock automatically.Owing to the invention solves the difficult problem that the common spring lock can not be antifouling, therefore can make existing door lock simultaneously, cabinet door lock, the copper key on the lock changes the aluminum key into, can save a large amount of rare precious metals like this, also very simple, the easy system of technology.

Below in conjunction with accompanying drawing the present invention is described specifically:

Figure 10 is that embodiment 5 uses schematic diagram (inner sketch)

As shown in Figure 1: be embodiment 1(door lock) main body and partial sectional view.The 1st, the key of unblanking.The 2nd, back-up ring, the 3rd, lock body, the 4th, antifouling key, the 5th, pellet shot from a slingshot, the 6th, little spring, the 7th, the keyhole on the lock core, the 8th, lock handle, the 9th, big spring, the 10th, antifouling centre bore.Unblank key 1 inserts keyhole 7 backs and antifouling key 4 stressed joints, after key 1 all inserts keyhole 7, antifouling key 4 in the keyhole 7 is squeezed to contract to inside center hole 10, big spring 9 also is forced to tighten in the hole simultaneously, in key 1 splits off lock or foreign material when blocking in the keyhole 7, antifouling key 4 is understood it is ejected outside the lock.

Fig. 2 is antifouling key lateral view, and Fig. 3 is a tapered end part schematic diagram; Antifouling key 4 penetrates connecting rod 11 and enters in the keyhole 7.

Fig. 4 is an embodiment 2(padlock) the front analyse and observe inner sketch: the 13rd, lock body, the 14th, lock pin, the 15th, stalloy in the lock pin has a Shen Yuan hole 10 that does not penetrate lock body on the top of lock body 13, and its aperture should be less than lock core diameter greater than keyhole 7 diameters and straight-through with it.

Fig. 5 is an embodiment 3(cabinet door lock) the main body side view: the 16th, tapered end, the 17th, shell, the 18th, the lock in body portion,

Fig. 6 is embodiment 3 internal construction schematic diagrames: the 19th, and the fixedly shifting block of lock core the inner, the 20th, the circular hole of antifouling key bottom.The 21st, fixing inserted sheet.

Fig. 7 is the internal construction lateral view of embodiment 3: the 23rd, and shell, the 19th, fixing shifting block, the 22nd, lock core the inner.

Fig. 8 is an embodiment 4(lock) the internal construction schematic diagram: but antifouling key 4 penetrates lock core the inner fixing metal sheet 24,25th, fixing primary screw, the 26th, dead bolt, the 27th, tapered end inner end portion, the 28th, shell.

Fig. 9 is an embodiment 5(lock) the internal construction schematic diagram: the 29th, body portion and antifouling key 4 and the tapered end part is direct-connected connects in the lock.

Figure 10 is the front section view of example 5: antifouling key 4 is advanced to lock in the centre bore 9 of endosome 29 by lock key 1 compression, end lock after, key 1 is ejected outside the lock by antifouling key 4.
