Description

A kind of anti-theft lock and key

Technical field:

The utility model relates to a kind of lock core and supporting key thereof, specifically a kind ofly be suitable for being installed in security door, safety cabinet, and lock core on other anti-theft appliances and supporting key thereof, this lock core can with the supporting use of traditional anti-theft appliance, reach unprecedented anti-theft effect.

Background technology:

The lock core of on China market, selling, almost 100% all use traditional setting billiards structure, be that the pellet shot from a slingshot arrangement is 90 degree right angles with the key direction of insertion in the lock core, this design has continued more than 1,000 year, never changed, it is easy to produce, easy to use, can be described as the crystallization of the wisdom of humanity, but also there are several defectives in traditional setting billiards structure: the diameter that at first is setting billiards structure requirement lock core is bigger, little for lock core is done, have to sacrifice pellet shot from a slingshot stroke (conventional lock cylinders pellet shot from a slingshot stroke generally is no more than 2 millimeters), and the pellet shot from a slingshot stroke is directly connected to the difficulty and the size of key of technology unlocking; Next is to erect pellet shot from a slingshot to arrange linearly type, and unlocking tool is as long as back and forth pulling just can shake all pellets shot from a slingshot easily, and safety factor is not high; Be because hole spacing is long at last, can't use superhard metal (as stainless steel) to make in batches, the lock core solidness can not get improving all the time.

Summary of the invention:

The purpose of this utility model improves the anti-theft lock of size of key for a kind of pellet shot from a slingshot stroke that increases is provided under the situation that does not increase lock core diameter.

The technical scheme that realizes above-mentioned purpose is as follows:

A kind of anti-theft lock, comprise lock tube and be located at lock tube interior rotor, spring, spring marble and teeth groove pellet shot from a slingshot, described rotor axial has the pellet shot from a slingshot hole, described pellet shot from a slingshot hole is along circumferential arrangement, described pellet shot from a slingshot hole is divided into two sections of different inner diameters, forms shoulder two sections junctions, and the internal diameter that inserts a side at key is less, described teeth groove pellet shot from a slingshot and this pellet shot from a slingshot hole are suitable, are divided into two sections of various outer diameter; Be fixed with a stator in the described lock tube, described stator center place has an axis hole, the driving lever that is fixedly arranged on the inboard end central part of rotor passes all holes of stator center, the lock tube outside has a shape plectrum that is connected with driving lever, described stator and the rotor corresponding pellet shot from a slingshot hole that is provided with of one side that contacts, in be provided with spring and spring marble.

Described lock tube is provided with a lead on the inwall of entrance.

Described stator is that multilayered metal film is stamped to form.

Axially have the AB key steel ball hole of hiding oneself on the described rotor, be provided with an AB key steel ball in the pellet shot from a slingshot hole of rotor.

Another purpose of the present utility model realizes that for providing a kind of and above-mentioned anti-theft lock supporting key the technical scheme of its purpose is as follows:

A kind of key comprises holding by portion and conciliates the lock section, axially has teeth groove on the described front end face of separating the lock section.

The utility model designs for the defective that solves conventional lock cylinders just, the change of its maximum is to have abandoned the setting billiards structure, to erect billiards structure and make to be horizontal billiards structure into, not only size of key and pellet shot from a slingshot stroke promote greatly for it, most importantly: it can use superhard metal manufacturing (such as stainless steel, conventional lock cylinders can't be used the stainless steel volume production).

Specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Shown in Fig. 2-5, a kind of anti-theft lock, comprise lock tube 1 and be located at lock tube interior rotor 2, spring 9, spring marble 10 and teeth groove pellet shot from a slingshot 4, described rotor 2 axially has pellet shot from a slingshot hole 11, and described pellet shot from a slingshot 11 holes are along circumferential arrangement, and described pellet shot from a slingshot hole is divided into two sections of different inner diameters, form shoulder two sections junctions, the internal diameter that inserts a side at key is less, and described teeth groove pellet shot from a slingshot and this pellet shot from a slingshot hole are suitable, is divided into two sections of various outer diameter; Be fixed with a stator in the described lock tube, described stator center place has an axis hole 13, the driving lever 5 that is fixedly arranged on rotor 2 inboard end central parts passes all holes of stator center, and lock tube 1 outside has one and is connected with driving lever Shape plectrum 6, described stator and the rotor corresponding pellet shot from a slingshot hole that is provided with of one side that contacts, in be provided with spring and spring marble.

Described lock tube is provided with a lead 8 on the inwall of entrance.

Described stator is that multilayered metal film is stamped to form.

As shown in Figure 4, axially have the AB key steel ball hole 12 of hiding oneself on the described rotor, be provided with an AB key steel ball in the pellet shot from a slingshot hole of rotor.

Described rotor and driving lever are an integral body.As being connected as a single entity by welding.

Described stator is fixed on lock tube inside by welding or dead bolt 7.

Shown in Fig. 6-7, a kind of key comprises holding by portion 14 and conciliates lock sections 15, axially has teeth groove 16 on the described front end face of separating lock section 15.

Described separate have on the lock section with lock tube on the gathering sill 17 that adapts of lead.

Below with reference to Figure of description, the course of work of the utility model lock core is done following explanation:

As shown in Figure 2: lock tube one end is provided with lead, and separating of key as shown in Figure 7 has gathering sill on the lock section, so key can only insert lock core by a direction; Stator is fixed on institute and puts, and the driving lever of rotor inserts the axis hole of stator center, and rotor can rotate freely; The big end of pellet shot from a slingshot hole one end of rotor is little, and also the big end of an end is little for the teeth groove pellet shot from a slingshot, and the teeth groove pellet shot from a slingshot can not drop out after inserting rotor.

Lock tube hollow, stator is fixed on the lock tube, can not rotate, the long driving lever of rotor inserts in the centre bore of stator, and driving lever one end is being fixed plectrum, when rotor rotates, plectrum also can rotate simultaneously, and the spring marble in the stator enters under the pressure of spring in the pellet shot from a slingshot hole of rotor, the teeth groove pellet shot from a slingshot in the extruding rotor, spring marble is between rotor and the stator, and rotor was tacked to rotate promptly and locked this moment; After key inserted lock core by gathering sill, the teeth groove of key and teeth groove pellet shot from a slingshot coincide, and support the coach spring pellet shot from a slingshot, form a plane, and rotor is promptly rotatable, thereby realized unblanking.

Rotor has the AB key steel ball hole of hiding oneself, this hole is exclusive, and the degree of depth is consistent with diameter of the steel ball, during installation steel ball is contained in any one hole of rotor all can, when using the A key, steel ball can stay in original position all the time, in case after turning over the B key, steel ball is earlier by in the pellet shot from a slingshot hole of jacking stator, when forwarding steel ball to and hide oneself the position, hole, steel ball can enter the steel ball hole of hiding oneself, and from then on can not come out again, takes this moment the A key unlocking just invalid again.

AB key design principle is identical with traditional locks, therefore only does above roughly narration.
