Abstract
The utility model provides an anti-drilling lock head, which relates to a key part on various spring locks. The anti-drilling lock is characterized in that a lock head cover is additionally arranged on the existing lock head, a main anti-drilling wheel and an auxiliary anti-drilling wheel which can rotate freely are arranged on the lock head cover, the main anti-drilling wheel is arranged at the position of a lock core, the auxiliary anti-drilling wheel is arranged at the position corresponding to a key tooth, and the lock head cover with the anti-drilling wheel is sleeved on the lock head and fixed. Its advantages are simple structure and high effect on preventing drilling. The lock head cover can be used for modifying the existing lock head and installing the existing lock head into the lock head cover when a lock is manufactured in a lock factory, and can also be independently processed to be matched with the existing sold lock.
Description
The Anti-drilling lock that the utility model provides relates to the critical component on existing various pin tumbler lockes and other cylinder lock.
Tapered end on existing widely used various pin tumbler lockes and other cylinder lock is its main element, it is made simply, cost is low, be difficult for sled etc., but in the existing robbed or burgled case, the normal stealer that takes place adopts lock core in the bad tapered end of bit drills reaching the purpose of committing theft, and the safety of existing cylinder lock is reduced.
The purpose of this utility model is to improve a little on the basis of existing cylinder lock, solves anti-drilling problem on the basis that keeps original tapered end advantage.
Concrete technical scheme provides a kind of novel tapered end, on existing tapered end, install tapered end cover additional, have main anti-drilling hole and the secondary anti-drilling hole of taking turns of taking turns on it, rotating master is anti-drilling to take turns and the secondary anti-drilling anti-lock wheel of the master on the tapered end cover hole and secondary anti-drilling the wheel in the hole respectively of taking turns, the main anti-drilling lock core hole place that is contained on the tapered end of taking turns, secondary anti-drilling the wheel is contained in the corresponding side of key bit on the tapered end, and main anti-drilling the wheel has keyhole.
The tapered end cover that is provided is the thin wall cylinder of thickness, it is sleeved on the tapered end, the anti-drilling hole of taking turns of master on the tapered end cover is interior greatly outer little frustum hole or shoulder hole with the secondary anti-drilling hole of taking turns, main anti-drilling the wheel and secondary outer rim shape and its corresponding matching of preventing wheel, and can freely rotate in the hole separately.
The advantage of this programme is that structure is very simple, can effectively solve anti-drilling problem, and it can be when Lock Factory's lockmaking, will have tapered end transformed this tapered end cover of packing into now, also can process this tapered end cover separately, to the supporting use of the lock of now having sold.
Further specify the content and the embodiment of this programme below in conjunction with accompanying drawing.
Fig. 1 is the front view of Anti-drilling lock, and Fig. 2 is the A-A sectional view of Fig. 1.(1) is tapered end cover among the figure, and (2) are anti-drilling wheel of master on the tapered end cover, and (3) are secondary anti-drilling the wheel, and (4) are keyhole, and (5) are tapered end, and (5 ') are lock core.The lock core of existing cylinder lock pierces from keyhole or key bit corresponding position all to have lock to be destroyed with drill bit and open.For this reason, the Anti-drilling lock that has tapered end cover that the utility model provides adopts that rotating master is anti-drilling takes turns (2) and secondary anti-drilling wheel the (3) solved, tapered end cover (1) is the thin wall cylinder of the thick end, have main anti-drilling take turns hole and secondary anti-boring at the end, big outer little in this hole, can be ladder or trapezoidal, major and minor anti-drilling the wheel is corresponding stairstepping or trapezoidal, anti-drillingly take turns that the major-minor that is respectively charged on the tapered end cover (1) is anti-drilling takes turns in the hole with major and minor, then tapered end cover is contained on the tapered end, and with its affixed getting final product.Main anti-drilling wheel the (2) is contained in the lock core place of tapered end (5), secondary anti-drilling wheel the (3) is contained in the corresponding position of key bit, general lock is adorned anti-drilling a wheel with the anti-wheel of a pair of master and is got final product, some key bit is tooth both direction or a plurality of direction layout on lock core, can arrange secondary anti-drilling the wheel by the direction that key bit is arranged like this.After installing anti-drilling the wheel additional, can insert in the keyhole of tapered end, must open keyhole (4) on main anti-drilling wheel the (2) for making key.
The anti-drilling wheel can not be excessive with the gap of tapered end, can freely rotate as long as guarantee anti-drilling the wheel, bores when destroying lock core in case stealer is used, and anti-drilling the wheel can be rotated with drill bit, and drill bit can not be cut, to reach anti-drilling purpose.
Claims (2)
1, a kind of Anti-drilling lock, it is characterized in that on tapered end, installing additional tapered end cover, have main anti-drilling hole and the secondary anti-drilling hole of taking turns of taking turns on it, rotating master is anti-drilling to take turns and secondary anti-drillingly takes turns that the master who is contained in respectively on the tapered end cover is anti-drilling to take turns hole and secondary anti-drilling the wheel in the hole, the main anti-drilling lock core place that is contained on the tapered end of taking turns, secondary anti-drilling the wheel is contained in the corresponding side of key bit on the tapered end cover, and main anti-drilling the wheel has keyhole.
2, a kind of Anti-drilling lock according to claim 1, it is characterized in that tapered end cover is the thin wall cylinder at the thick end, it is sleeved on the tapered end, the anti-drilling hole of taking turns of master on the tapered end cover is interior big outer little trapezoidal hole or shoulder hole with the secondary anti-drilling hole of taking turns, main anti-drilling the wheel and secondary anti-drilling outer rim shape of taking turns and its corresponding matching, and can freely rotate in the hole separately.
