Abstract
The utility model relates to an anti-drilling convenient lock which comprises a lock core, a lock body, a lock bead, a spring, a key, and a conductive part. The utility model is characterized in that an anti-drilling arranged on the side of the end of a key-insertion whose end surface is closed over with only a key hole arranged in the center of the end surface and a key with a rectangular section key body are arranged; various top bead pits whose depth is proportional to the diameter of a pitted surface is respectively arranged on four side surfaces of the key body; the lock core and the lock body of four lock bead holes are arranged at the position of top bead pit opposite four side surfaces of the key body. The utility model has the advantages of simple and compact structure, anti-drilling function, large size of key, low mutual unlocking rate, high confidentiality, strong anti foreign matter opening ability, little possibility of imitating key, flexible and convenient use, etc.
Description
The utility model relates to a kind of anti-drilling convenient lock, particularly relates to a kind ofly can preventing to drill lockset, can use no key bit structure key and having that key is convenient to insert and key has anti-drilling convenient lock of two-sided unlocking function.
Lockset general in the prior art includes lock core, lock body, the lock pearl, spring, key and conducting piece, the most number average of its lock core and lock body adopts copper material to make, therefore its hardness is lower, and no matter its key is in-line, herringbone or cross etc., all be to adopt the key bit structure, therefore, these locksets all have the following disadvantages: 1. easy stolen person drills lock core or lock body by drill bit and lock body is bored saturating, rotational lock head is opened lockset, can not guarantee antitheft effectively, even some confidentiality are higher, the lock that mutual opening rate is lower also is difficult to avoid the thief to use drill bit that lock is drilled under situation about can't unblank, open lockset; 2. security performance is low, mutual opening rate is high; 3. foreign matter unlocking rate height; 4. key is easily imitated; 5. key only can be fixed position and insert keyhole, differs certain angle (as cross and herringbone key) or 180 degree (as the in-line key) with the permanent position when drawing out key and insert, and just can't unblank, and causes the very inconvenience in the use.
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, have anti-drilling function, size of key is big, mutual opening rate is low, security performance is high, anti-foreign matter unlatching ability is strong, key is difficult for imitated, anti-drilling convenient lock flexible and convenient to use.
The purpose of this utility model can reach by following measure: anti-drilling convenient lock includes lock core, lock body, lock pearl, spring, key and conducting piece, it is characterized in that also comprising and be provided with: a. be installed in insert spoon end one side, and with this side end face capping and only therein the heart offer the anti-drilling mechanism of a keyhole, to play the anti-drilling effect that stops drill bit to pierce; B. square-section spoon body key, four sides of spoon body are respectively equipped with the decorative pearl on top of an official cap pit that the various degree of depth and pitted surface diameter thereof are directly proportional, under the situation of the decorative pearl on top of an official cap that uses same diameter, decorative pearl on top of an official cap pit is dark more, its pitted surface diameter is just big more, shallow more its pitted surface diameter is just more little, c. relatively four sides of spoon body decorative pearl on top of an official cap groove position and the four sides be set lock the lock core and the lock body in the hole of bead, lock pearl and key in the lock hole of bead are cooperatively interacted.Thereby make to have anti-drilling function, make it to carry greatly the permutation and combination number, improve size of key, reduce mutual opening rate, and it is convenient to insert spoon.
The purpose of this utility model can also reach by following measure: (〉=HRc55) stator and sheath constitutes the anti-drilling mechanism of anti-drilling convenient lock by possessing 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.The stator of above-mentioned anti-drilling mechanism and sheath can be to be stator and the sheath that the A3 cold-rolled steel sheet of HRc60 or HRc65 is made through Carburization Treatment, case hardness.
The purpose of this utility model can also reach by following measure: the key of anti-drilling convenient lock can respectively be provided with two row's decorative pearl on top of an official cap pits, two sides reverse symmetry each other up and down on the two sides of broad, and key can respectively be provided with row's decorative pearl on top of an official cap pit and symmetry each other on narrower two sides.Non-directional when making key insert the keyhole of lock core, be convenient to unblank rapidly, simultaneously more number of combinations of tool and higher confidentiality again.The key of this anti-drilling convenient lock can also be arranged between the decorative pearl on top of an official cap pit in two on the two sides of broad be provided with guide groove, and guide groove position lock core inner hole wall is provided with guide rail relatively, is convenient to insert rapidly spoon and reaches key guiding and location.
The purpose of this utility model can also reach by following measure: the key spoon body terminal part of anti-drilling convenient lock can be to be the duckbill structure.So that insert key quickly and accurately.
The purpose of this utility model can also reach by following measure: the unlatching and the sealed controlling organization of anti-drilling convenient lock are made of key, the decorative pearl on top of an official cap, flat pearl, spring and envelope pearl, the decorative pearl on top of an official cap, flat pearl, spring pack in the lock hole of bead of lock core and lock body successively, and seal on lock body tightly with the envelope pearl, and decorative pearl on top of an official cap leading portion is that cone, stage casing are step-like less than back segment.To guarantee quality of fit.
