Description

Hiding security lock

The utility model relates to a kind of theftproof lock.

At present, sale and theftproof lock used in everyday are mostly by being provided with the effect that multiple pellet shot from a slingshot, multidigit password or a plurality of mutual interlocking gear reach antitheft or pick-proof on the market, this theftproof lock all has lock body, locking bolt, lock core or number implement, and lock core or number implement all expose, therefore the robber still can pry open lock maybe with master key, special instrument, sharp weapon or blunt lock is broken, so the effect of the antitheft or pick-proof of these theftproof locks is also desirable not to the utmost.

Task of the present utility model provides a kind of can't prying open with common or master key, also the Hiding security lock that can't break with sharp weapon and blunt.

Task of the present utility model is finished like this: on the base plate of the present utility model locking bolt is installed, also has a straight trough on the base plate, trough rim has at least one plate washer parallel with straight trough, there is a curve geosynclinal block in the plate washer outside, the curve plane of curved groove is vertical with the plate washer plane, a contact pin is arranged in the curved groove, and it is connected interlock by one group of machine components with locking bolt.

Contact pin preferably sinks in the curved groove 1～1.5 centimetre, and is arranged on the end of curve.Making the machine components of locking bolt and contact pin interlock can be a lever part, also can comprise one group of part such as pin rod, alignment pin, return spring, gear, drag-line, pulley and handwheel.

Because the utility model is provided with straight trough, plate washer parallel with straight trough and curve geosynclinal block are arranged, this is and the diverse lock-key device of the theftproof lock of routine, closing on the also locked door, can only see the straight trough and a handle at a no end, and not too big the contacting directly of the position of the position of straight trough and locking bolt, have only the plane curve key of using the curve shape with curved groove to fit like a glove just can stir contact pin and effectively lock is opened.And the robber inserts from straight trough with master key or other special instrument, can visit not on earth, also touch less than the limit, can't know the shape of curved groove and key at all, can't touch contact pin at all, the theft business such as can't set about to prize, dial, bore, pound, thereby lock and door can't be removed at all, as seen the utlity model has extremely strong antitheft and pick-proof effect.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the structural representation of a kind of embodiment of the utility model.Fig. 2 is that A among Fig. 1 is to view.Fig. 3 is the schematic diagram that is fit to the key of curved groove among Fig. 2.

As shown in Figure 1, on the base plate 1 of the utility model lock, locking bolt 2 is installed, also has a straight trough 3 on the base plate, trough rim has a plate washer parallel with straight trough 4, there is a curve geosynclinal block 5 in the plate washer outside, and the curve plane of curved groove 6 is vertical with the plate washer plane, and a contact pin 7 is arranged in the curved groove.For improving anti-theft feature, two even three plate washers parallel with straight trough can be set on the straight trough limit, the plane curve key that has only the curve shape with the gap of plate washer and curved groove to fit like a glove could insert in the curved groove that changes the curve geosynclinal block then over to along straight trough and promote contact pin, make the machine components of locking bolt 2 and contact pin 7 interlocks comprise pin rod 8, alignment pin 9, alignment pin return spring 10, gear 11, drag-line 12, pulley 13 and handwheel 14, be shaped on the locking bolt 2 can with the tooth bar 15 of gear 11 engagement, pin rod 8 firmly is connected with contact pin 7, alignment pin 9 is horizontal, its left end can insert in the locating slot 16 of pin rod 8, pin rod 8 is perpendicular to be put, and its lower end can be inserted in the cotter way 17 on the locking bolt 2.As shown in Figure 2, curved groove 6 can be made into the shape of many curved plane curves in the curve geosynclinal block 5, also can be made into animal or certain peculiar shape, as long as the shape of the key head of insertion straight trough and the shape of curved groove fit like a glove, (Figure 3 shows that the schematic diagram of the key of the curved groove that adapts to many curved plane curves.) contact pin 8 can be arranged on any position in the curved groove 6, but be preferably disposed on

The end of the curve in the curved groove, and 1～1.5 centimetre of enough degree of depth to be arranged apart from the end face of curve geosynclinal block, to improve the disguise of contact pin.The handle 18 with Men Lakai is installed in the outside of door, and the door limit is fixed with the buting iron 19 that shelters from locking bolt.

For improving antitheft and the deterrence effect, also the contact that is connected with alarm can be installed on the end face of curve geosynclinal block.In case the robber will make alarm send chimes of doom with the instrument picking lock and when touching the contact.When opening the door, rotate earlier handwheel 14 slightly, make drag-line 12 overcome the elastic force of return spring 11, pulling alignment pin 9, make it to break away from pin rod 8, with key contact pin 7 and pin rod 8 are picked up again and tooth bar 15 breaks away from, rotate again that handwheel 14 driven gears 11 rotate and shooting the lock-bolt 2 moves, lock is opened, used handle 18 again Men Lakai.The utility model is not only applicable to various common door locks such as family expenses door lock, cabinet door lock, also is specially adapted to the door lock of important departments such as bank, warehouse, train wagons and instrument.
