Abstract
The invention discloses a dynamic balance lock core, which comprises an outer lock core, an inner lock core and a key, wherein the inner lock core and the key are sleeved in the outer lock core; when the lock core is in a locked state, one end of the dynamic balance bolt is inserted into the groove of the outer lock core, and when a key is inserted to open the lock core, the protruding parts at the two ends of the dynamic balance bolt are positioned on the interface of the inner lock core and the outer lock core; the invention adopts the dynamic balance bolt to replace the prior marble or blade to lock the inner lock core and the outer lock core, and has the characteristics of high opening difficulty, high violent damage prevention and the like.
Description
Technical field
The present invention relates to a kind of lock core, particularly a kind of lock core that replaces existing pellet shot from a slingshot or blade by high strength, high theftproof performance, the simple dynamic equilibrium bolt of manufacturing.
Background technology
Make a general survey of all in the market locksets, no matter be the high-tech product of collection sound, light, mechanical, electrical one, still cylinder lock prevailing, that utilization rate is the highest or blade lock, in face of the method for unlocking of more and more advanced skilled unlocking means or violence damage, its strick precaution ability is more and more littler.As concerning electronic lock, can open with electronic technology means, also can destroy with strong magnetic, high temperature.To cylinder lock or blade lock, no matter its lock core structure is simply or complexity, all is regular following, easily by stir or vibrate technical methods such as pellet shot from a slingshot or blade several seconds to a few minutes drawback lock, or directly by force the means destructiveness unblank.Therefore, the safety of these pellets shot from a slingshot or blade lockset and theftproof performance are all not satisfactory.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of dynamic balancing lock pin, this lock core has high high strength that difficulty, high anti-violence destroy and the high characteristics such as antitheft of opening.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of dynamic balancing lock pin, comprise outer lock core, be sleeved on internal cylinder and key in the outer lock core, it is characterized in that being provided with groove in the described outer lock core, be provided with elongated slot in the internal cylinder, be provided with some dynamic equilibrium bolts in the elongated slot, described each dynamic equilibrium bolt is fixed in the elongated slot of internal cylinder by rotating shaft, and can rotate in elongated slot respectively; When lock core was in the lock state, an end of dynamic equilibrium bolt inserted in the groove of outer lock core; When inserting key operated lock core, the projection at dynamic equilibrium bolt two ends is positioned on the interface of internal cylinder and outer lock core.
As the preferred embodiment of the present invention, some magnet are installed in the described outer lock core, magnet is corresponding with an end of dynamic equilibrium bolt, and described dynamic equilibrium bolt is made by high-intensity magnetic metal material.
As another preferred embodiment of the present invention, in the described rotating shaft torsion spring is installed, so that an end of dynamic equilibrium bolt keeps inserting the interior state of groove of outer lock core.
Above-mentioned dynamic equilibrium bolt is provided with the inclined-plane, is provided with the platform that coincide with this inclined-plane on the key.
In order to strengthen the ability that anti-technical unlocking and anti-violence nature destroy, described elongated slot can be set to one, two, three or four, and some dynamic equilibrium bolts can be set in each elongated slot, and the quantity of groove is corresponding with elongated slot.
The invention has the beneficial effects as follows: the present invention adopts the dynamic equilibrium bolt to replace existing pellet shot from a slingshot or blade to lock inside and outside lock core, the dynamic equilibrium bolt is fixed in the elongated slot of internal cylinder with rotating shaft, can freely rotate around rotating shaft, the two ends projection all can insert in the groove of outer lock core in turn during rotation; In working order, dynamic equilibrium bolt one end keeps an end to insert in the groove of outer lock core under the effect of self gravitation or external magnetic force, spring force.When opening the lock with the key, the inclined-plane of inclined-plane on the key and dynamic equilibrium bolt coincide and contact fully, and when the projection at dynamic equilibrium bolt two ends all was on the interface of inside and outside lock core, the just rotatable and drive sword iron of internal cylinder was unblanked.When the shape of illegally unblanking is generation, no matter how to remove to stir or vibrate the dynamic equilibrium bolt, because the dynamic equilibrium bolt is to be in free state, and a dynamic equilibrium bolt group of being made up of a plurality of dynamic equilibrium bolts of a plurality of positions, illegal invasion person can't know and finds equalization point and do not drive lock; In addition, the dynamic equilibrium bolt is to be made by high-intensity magnetic metal material, so have the high characteristics such as difficulty, high anti-violence destruction of opening.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the right view of the lock core of two elongated slots;
Fig. 3 is the right view of the lock core of three elongated slots;
Fig. 4 is the right view of the lock core of four elongated slots;
Fig. 5 is the structural representation of dynamic equilibrium bolt.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of dynamic balancing lock pin disclosed by the invention, comprise outer lock core 1, be sleeved on internal cylinder 2 and key 3 in the outer lock core 1, in outer lock core 1, be provided with two grooves 4, be provided with two elongated slots 5 in the internal cylinder 2, be connected with three dynamic equilibrium bolts 8 in turn by rotating shaft 7 in the elongated slot 5, and can in elongated slot 5, freely rotate.
Some magnet 9 are installed in outer lock core 1, each magnet 9 is corresponding to an end of a dynamic equilibrium bolt 8, dynamic equilibrium bolt 8 is to be made by high-intensity magnetic metal material, when lock core is in the lock state, dynamic equilibrium bolt 8 one ends insert in the groove 4 of outer lock core 1 under the effect of magnet 9 magnetic force, thereby lock inside and outside lock core.Certainly, the torsion that dynamic equilibrium bolt 8 also can rely on self gravitation or be arranged on the torsion spring in the rotating shaft 7 inserts in the groove 4 of outer lock core 1, is not described further at this.
With reference to Fig. 1, Fig. 5, dynamic equilibrium bolt 8 is provided with inclined-plane 10, key 3 is provided with the inclined-plane 6 that coincide with this inclined-plane 10, when inserting key operated lock core, inclined-plane 6 on the key coincide with the inclined-plane of dynamic equilibrium bolt 10 and contacts fully, at this moment the projection at dynamic equilibrium bolt 8 two ends is on the interface of inside and outside lock core, and internal cylinder 2 is rotated and driven sword iron and unblanks.
In order to strengthen the ability that anti-technical unlocking and anti-violence nature destroy, lock core of the present invention can be made up of single groove single face three bolts, two-sided three to six bolts (Fig. 2) of single groove, three-flute three to six bolts (Fig. 3), four grooves, four to eight bolts (Fig. 4), front and back two-section lock core or the like, and the quantity of the groove 4 in the outer lock core 1 is corresponding with the quantity of the elongated slot of internal cylinder 2.
The above only is a preferred embodiment of the present invention, can not limit protection scope of the present invention with it.So long as the equalization of doing according to protection scope of the present invention changes and modify, all should still belong in the scope that the present invention contains.
