Abstract
Many key pins lock core and key thereof belong to a kind of lockset, are made up of lock core, core body and key.It is characterized in that having one to be positioned at the master key hole of center and radially-arranged secondary keyhole more than, a master key and more than one secondary key are arranged.This lock core can be set up the special purpose system of each lock core according to key numbering, and its structure is still simpler, but secrecy improves greatly, and other people are difficult for cracking, and are if a plurality of keys of a lock core are disperseed to deposit, just more reliable.So the present invention can be used as the demanding lockset of security insurance, also can become some important storehouses and place are carried out effective lockset that many people guard.
Description
The invention belongs to the demanding lockset of a kind of lockset, particularly security insurance.
The principle of " opening different locks with different keys " is all followed in the design of current cylinder lock, and this lockset is simple in structure, but theftproof performance is poor, is difficult to be competent at the usefulness of the defence of locating such as bank vault, archives material, secret place, valuable storehouse etc.For this reason, the patent application that has manages to improve the complexity of lock core and Key structure, and certainly, this has also just improved required precision and manufacturing cost simultaneously, and in case key loss or stolen, this lock just loses effectiveness thereupon.Be also pointed out that this kind cylinder lock, be not easy to some important storehouses and place are carried out necessary many people's guards.
The purpose of this invention is to provide a kind of many key pins lock core and key thereof that has only the required a plurality of keys of insertion to open.
Many key pins lock core of the present invention is made up of lock core, core body and key, it is characterized in that lock core has one to be positioned at the master key hole of lock core center and radially-arranged secondary keyhole more than, a master key and more than one secondary key.
This many key pins lock core, because a plurality of keys of same lock core can separately be deposited keeping, the user needs only the key numbering, and in view of the above with the lock core coding, just can select required key for use according to the special purpose system of a certain lock core.The structure of this lock core is still simpler, but can improve its privacy degrees greatly, even key is all lost or be stolen, other people also are difficult to crack for the moment, the user can disperse a plurality of keys of a lock core to deposit fully still more, and the bad man is with regard to rareer having shown off so.So the present invention can be used as the demanding lockset of security insurance.
Many key pins lock core of the present invention can also become some important storehouses and place are carried out effective lockset that many people guard, and it is just passable as long as respectively hold a key to participate in the bailiff.
Now with following all embodiment and description of drawings structure of the present invention thereof.
Fig. 1 is focus type three key pins lock cores and core body front view.
Fig. 2 is the A-A sectional view.
Fig. 3 is a master key.
Fig. 4 is secondary key.
Fig. 5 is a big envelope.
Fig. 6 is distributing three key pins lock core front views.
Fig. 7 is five key pins lock core front views.
Embodiment 1: as shown in Figure 1, be a kind of focus type three key pins lock cores, three keyholes are mutually 90 ° of angles, radial distribution also intersects at the center, middle (being in the lock core center) is master key hole [1], both sides are secondary keyhole [2], this lock core is when carrying out unlock operation, to insert master key [9] (as shown in Figure 3) earlier, side direction is inserted two secondary keys [10] (as shown in Figure 4) respectively perpendicular to master key and the side of being close to master key then, so this lock core also can be described as orderly three key pins lock cores.
In like manner, if with a secondary key, just become focus type two key pins lock cores.
Embodiment 2: as shown in Figure 6, be a kind of distributing three key pins lock cores, three keyhole radial distribution become any angle and disconnected from each other, but master key hole [1] still occupies the center of lock core.As shown in Figure 7, distributing five key pins lock cores also are so, just many two keys.
As shown in Figure 2, [3] are lock core.[4] be core body.[5], [6], [7] be respectively do not wait the long marble pin, etc. long marble pin and spring, its quantity master key respectively is 4~6 pieces, secondary key respectively is 3~5 pieces.[8] for blocking the big envelope of whole pellet shot from a slingshot pins and spring, [11] are the installing hole (as shown in Figure 5) of pellet shot from a slingshot pin and spring, also can adopt filler rod to block respectively.
Claims (5)
