Abstract

The utility model relates to a lock head, in particular to a composite lock head, where a sub-clock head, a primary lock head, a sub-key and a primary key are connected as a whole. The utility model overcomes the disadvantage that the lock head is not very safe as the lock head can hook the lock blade through the key hole. The technical proposal is that: the composite lock head comprises a lock head body, a lock core that is arranged inside the lock head body, and a key that is matched with the lock core, wherein, the lock head body is fixed on an anti-drilling sleeve by means of pins; an anti-drilling sheet is arranged between the lock core and the anti-drilling sleeve; the lock core and the lock head body are clipping connected by a clipping ring; the inner walls of the two sides of the lock core are provided with a plurality of springs and beads. The utility model is characterized in that the lock core comprises a primary lock core and a sub lock core, both of which are connected together to be arranged inside the lock head body; the extension sub-key is arranged on the primary key; the terminal of the sub lock core is connected with a transmission sheet; the bottom hole of the primary lock core is provided with the key hole; the sub-key holes of the bottoms of the sub lock core hole and the primary lock core hole are staggered by a certain angle and are in the same circumference. The utility model can be used in the locking tools that need high safety, such as the lock of the bedroom door, the lock of the vehicle door and the lock of the cabinet.

Description

Combined lock device

One, technical field

The utility model relates to a kind of tapered end, particularly the Combined lock device that fuses of a seed tapered end, female tapered end, sub-key, mother key.

Two, background technology

Existing tapered end generally comprises tapered end and is contained in the interior lock core of tapered end, near the keyhole place, between lock core and tapered end, be provided with anti-drilling sheet, lock core both sides inwall is provided with some spring marbles, pellet shot from a slingshot stretches out the lock core inwall, its length and tooth depth on the key are complementary, and the lock core tail end is connected with driver blade.The shortcoming of this tapered end is that safety is not high, can directly visit locking plate by keyhole, and the thief opens the door not to be needed key and pound lock, directly the door lock hook can be opened with thin wire.

Three, summary of the invention

The utility model technical issues that need to address are: design a kind of structure of tapered end, can't open tapered end by a single key, and can't see locking plate by keyhole, also can't be hooked to locking plate with iron wire.The technical solution of the utility model is: Combined lock device, comprise tapered end and be contained in the interior lock core of tapered end, and and the key that is complementary of lock core, tapered end puts anti-drilling by dowel fixes, between lock core and anti-drill bushing, anti-drilling sheet is arranged, between lock core and the tapered end by the collar clamping, lock core both sides inwall is provided with some springs, pearl, it is characterized in that: lock core comprises female lock core and sub-lock core, abut against and be placed in together in the tapered end, telescopic sub-key is placed on the mother key, and sub-lock core tail end is connected with driver blade, at the bottom of female lock core, have sub-keyhole, stagger certain angle and on same circumference of sub-lock core hole and female lock core hole bottom keyhole.When mother key is flat-shaped, on mother key, have sliding tray and sub-key, sub-key clamping wherein, son has on the key and is connected in the sliding tray and can promotes its flexible push button, push button is by sub-key lid stator key, and the length of sub-key and width are less than mother key.When mother key was column, this cylinder was a hollow cylinder, sub-key socket wherein, the mother key place of shaking hands has sliding tray, son has on the key and is connected in the sliding tray and can promotes its flexible push button, the length of sub-key and width are less than mother key.The beneficial effects of the utility model are: because lock core is divided into female lock core and sub-lock core, key is divided into mother key and sub-key, and female in off position lock core hole and sub-lock core hole be not at same axis, use a single key tapered end can't be opened, and can't the locking plate hook be opened by iron wire, increased the safety of lock greatly.

Four, description of drawings Fig. 1 is that the utility model cross section structure schematic diagram Fig. 2 is among the utility model embodiment 1 sub-Key structure schematic diagram figure for the utility model embodiment 1 mother key structural representation Fig. 3: the 1-driver blade, 2-lock core, the 3-collar, 4-spring, pearl, the 5-pin, 6-prevents drill bushing, the 7-anti-drilling sheet, the female lock core of 8-, 9-tapered end, 10-mother key, the 11-sliding tray, 12-key, 13-key, 14-key lid, the 15-push button, the female lock core hole of 16-, 17-keyhole, 18-lock core hole.
