Abstract
The utility model relates to an anti-drill lock which comprises a lock core, a lock body, a lock bead, a spring, a key and a conduction component. The utility model is characterized in that an anti-drill mechanism is arranged on one side of the end which can be inserted by the key, the end face of the side is sealed and covered, and only a key hole is arranged in the center of the anti-drill mechanism. The utility model has the characteristics of simple and compact structure, reasonable and beautiful appearance, good universality, anti-drill function, etc., and is fit for various locksets.
Description
The utility model relates to a kind of anti-drill lock, particularly relates to a kind of anti-drill lock of drilling lockset, being used for various occasions of can preventing.
General lockset includes lock core, lock body, lock pearl, spring, key and conducting piece in the prior art, the most number average of its lock core and lock body adopts copper material to make, therefore its hardness is lower, be easy to that stolen person drills lock core or lock body by drill bit and lock body bored saturating, rotational lock head open lockset, thereby can not guarantee antitheft effectively.Even some have security performance height, lock that mutual opening rate is low, also be difficult to avoid the thief under situation about can't unblank, lock to be drilled, open lockset by drill bit.
The purpose of this utility model be to avoid above-mentioned weak point of the prior art and provide a kind of simple and compact for structure, profile is rationally attractive in appearance, the anti-drill lock that is applicable to various locksets, has anti-drilling function.
The purpose of this utility model can reach by following measure: anti-drill lock includes lock core, lock body, lock pearl, spring, key and conducting piece, it is characterized in that also comprising being provided with anti-drilling mechanism that this anti-drilling mechanism is installed on and inserts spoon end one side, and with this side end face capping, only the heart is offered a keyhole therein.To play the anti-drilling effect that stops drill bit to pierce.
The purpose of this utility model can also reach by following measure: the anti-drilling mechanism of anti-drill lock can be that (〉=HRc55) stator and sheath constitute by high rigidity, stator is connected with the slotting spoon end of lock core, to prevent to drill lock core, sheath is contained in slotting spoon end one side of lock body, to prevent to drill lock body.Can also between the stator outer face of anti-drilling mechanism and sheath inner face, be provided with and possess high rigidity (〉=HRc55) activity template, when the drill bit of rotation touches activity template, activity template rotates with drill bit under the effect of frictional resistance, and do rotational slide with respect to hard stator, the power that pierces of drill bit is constantly disperseed, thereby can not pierce any position of lock core or lock body, play anti-drilling effect.The stator of above-mentioned anti-drilling mechanism, activity template and sheath can be that adopting by Carburization Treatment, case hardness is stator, activity template and the sheath that the A3 cold-rolled steel sheet of HRc60 or HRc65 is made.
The utility model is described in further detail to utilize accompanying drawing:
Fig. 1 is the structural representation of a kind of anti-drill lock of the present utility model.
In anti-drill lock shown in Figure 1, include conducting piece (1), lock core (2), cottor pin (3), lock body (4), the decorative pearl on top of an official cap (5), envelope pearl (6), flat pearl (7), spring (8), stator (9), activity template (10), sheath (11), pin (12) and key (13).
The utility model is described in further detail to utilize following examples:
A kind of anti-drill lock of the present utility model as shown in Figure 1, its anti-drilling mechanism can be that (〉=HRc55) stator (9) and sheath (11) constitute by having high rigidity, stator (9) is inserted the spoon end by welding or connector with lock core (2) and is connected, sheath (11) is contained in slotting spoon end one side of lock body (4) by pin (12), when the drill bit of rotation when stator (9) or sheath (11) advance, hard stator (9) or sheath (11) can stop the propelling of drill bit, play anti-drilling effect.
A kind of anti-drill lock of the present utility model as shown in Figure 1; can be provided with and possess high rigidity (〉=HRc55) activity template (10) between the stator of anti-drilling mechanism (9) outer face and sheath (11) inner face; when the drill bit of rotation is advanced to activity template (10); activity template (10) rotates with drill bit under the effect of frictional resistance; and on hard stator (9), do rotational slide; thereby the propulsive force of disperseing drill bit; make it to pierce any position of lock core (2) or lock body (4), play anti-drilling double protection.
It is that the A3 cold-rolled steel sheet of HRc60 or HRc65 is made that a kind of anti-drill lock of the present utility model, the stator of its anti-drilling mechanism (9), activity template (10) and sheath (11) all adopt by Carburization Treatment, case hardness.
A kind of anti-drill lock of the present utility model as shown in Figure 1, the key (13) that it is by conducting piece (1), have lock core (2) that cross lock pearl distributes, cottor pin (3), distribute with the corresponding lock body (4) of lock core (2) and the decorative pearl on top of an official cap (5) that is disposed, envelope pearl (6), flat pearl (7) and spring (8), cross key bit and the cross-key anti-drill lock of anti-drilling mechanism formation.
The utility model compared with prior art has following characteristics:
(1) simple and compact for structure, profile is rationally attractive in appearance;
(2) versatility good, be applicable to various locksets, cooperate with various antitheft, antitheft door, be used for the places such as family, hotel, bank and office;
(3) have anti-drilling function, reach and surpass the standard-required that can't bore in 15 minutes of GA25-92.
Claims (5)
1, a kind of anti-drill lock includes lock core, lock body, lock pearl, spring, key and conducting piece, it is characterized in that also being provided with anti-drilling mechanism, and this anti-drilling mechanism is installed in and inserts spoon end one side, and with this side end face capping, only the heart offers a keyhole therein.
2, anti-drill lock according to claim 1 is characterized in that (〉=HRc55) stator and sheath constitute, and stator is connected with the slotting spoon end of lock core, and sheath is contained in slotting spoon of lock body and holds a side by possessing high rigidity in said anti-drilling mechanism.
