Description
One, technical field
The utility model relates to a kind of tapered end, particularly a seed, female tapered end, two locking cams of the band protective device that son, mother key mate mutually.
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.Chinese patent ZL02215284.9 has introduced a kind of Combined lock device, this patent is divided into female lock core and sub-lock core with lock core, and 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, make a single key can't open door lock, but this tapered end exists the process of unblanking comparatively complicated, and the intensity of sub-key is also lower, fracture easily, driver blade is a whole piece, and is sawed-off, comparatively loaded down with trivial details if installation process has been grown needs.
Three, summary of the invention
The utility model technical issues that need to address are: simplify the process of unblanking, increase the anti-theft feature of tapered end, increase sub-key intensity, driver blade can be adjusted.A kind of tapered end and primary-secondary type key with protective device is provided.The technical solution of the utility model is: two locking cams of band protective 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 is fixed on the bonnet by screw; between lock core and the tapered end by the collar clamping; lock core both sides inwall is provided with some springs; pellet shot from a slingshot; pellet shot from a slingshot can magnetic and non magnetic in select for use; lock core comprises female lock core and sub-lock core, abuts against to be placed in together in the tapered end, and telescopic sub-key is placed on the mother key; sub-lock core tail end is connected with driver blade; female lock core hole is communicated with sub-lock core hole, and female lock core hole is a cylinder, and sub-lock core hole is the arcuation body.Between tapered end cover and lock core a spoon door gear is installed, the spoon door gear is connected in the housing by two spoon doors and back-moving spring and constitutes, spoon Men Yiduan clamping back-moving spring, and two spoon door other end butt joints form the guiding pit.Mother key is cylindric, comprises sub-key, and sub-key is and the arcuation body of sub-lock core hole coupling, is slidably contact between sub-key and the mother key, and the handle of mother key has sliding tray, and son has on the key and is connected in the sliding tray and can promotes push button that it stretches.Driver blade is made of fixed conveyor sheet and adjustable driver blade, and fixed conveyor sheet and adjustable driver blade are provided with a plurality of locating holes, and the fixed conveyor sheet is plugged in the adjustable driver blade, fixes by holding screw.The beneficial effects of the utility model are: owing to set up the spoon door gear at original anti-drilling sheet place, increased the safety of tapered end.By setting up magnetic bullet, making the combination variation of pellet shot from a slingshot has increased key density, has increased difficulty to technical unlocking.The composite cylindrical shape structure of primary and secondary keys and the connectivity structure of primary and secondary lock core had both increased the intensity of key, made that again the unlatching of tapered end is convenient and swift.The adjustable structure of driver blade makes the quick and easy for installation of driver blade, and is safe and reliable.

Among the figure: 1-driver blade, 1-1-fixed conveyor sheet, the adjustable driver blade of 1-2-, 1-3-locating hole, 1-4-holding screw, 2-lock core, 3-collar, 4-spring, pellet shot from a slingshot, 5-screw, 6-tapered end cover, 7-spoon door gear, 7-1-spoon door, 7-2-back-moving spring, 7-3-rivet, 7-4-cover plate, the 7-5-pit that leads, 7-6-housing, the female lock core of 8-, 9-tapered end, the 10-bonnet, 11-mother key, 12-sliding tray, 13-key, the 14-push button, the female lock core hole of 15-, 16-lock core hole, 17-handle.
Five, the specific embodiment
With reference to accompanying drawing 1; 2; 3; 4; 5; 6; two locking cams of band protective device; comprise tapered end 9 and be contained in the interior lock core of tapered end; and and the key that is complementary of lock core; tapered end 9 is fixed on the bonnet 10 by screw 5; between lock core and the tapered end 9 by collar 3 clampings; lock core both sides inwall is provided with some springs; pellet shot from a slingshot 4, pellet shot from a slingshot can magnetic and non magnetic in select for use, lock core comprises female lock core 8 and sub-lock core 2; abut against and be placed in together in the tapered end 9; telescopic sub-key 13 is placed on the mother key 11, and sub-lock core 2 tail ends are connected with driver blade 1, and female lock core hole 15 is communicated with sub-lock core hole 16; female lock core hole 15 is a cylinder, and sub-lock core hole 16 is a semicylinder.Between tapered end cover 6 and lock core, spoon door gear 7 is installed, the spoon door gear is connected in the housing 7-6 by two spoon door 7-1 and back-moving spring 7-2 and constitutes, spoon door 7-1 one end clamping back-moving spring 7-2, two spoon door 7-1 other end butt joints form guiding pit 7-5, the spoon door gear is fixed by cover plate 7-4 and rivet 7-3, mother key 11 is cylindric, comprise sub-key 13, sub-key 13 is the semicylinder that mates with sub-lock core hole 16, be slidably contact between sub-key 13 and the mother key 11, the handle 17 of mother key 11 has sliding tray 12, have on the sub-key 13 to be connected to also to promote its flexible push button 14 in the sliding tray 12, the extension elongation of sub-key 13 is 1/4 of a mother key 11.Dotted portion among Fig. 2,3 is sub-key and releases the back state diagram.Driver blade 1 is made of fixed conveyor sheet 1-1 and adjustable driver blade 1-2, and fixed conveyor sheet 1-1 and adjustable driver blade 1-2 are provided with a plurality of locating hole 1-3, and fixed conveyor sheet 1-1 is plugged in the adjustable driver blade 1-2, and 1-4 fixes by holding screw.
When opening door lock, key bit withstands in the guiding pit 7-5 of spoon door 7-1, because the effect of external force makes spoon door 7-1 by the outside mobile back-moving spring 7-2 compression that makes in center respectively, 7-1 opens up into certain limit when the spoon door, can insert key, insert mother key 11 earlier, promote push button 14 then and insert sub-key 13, tapered end can be opened.After unblanking, pull out sub-key 13 earlier, and then pull out mother key 11.Because employing can be regulated driver blade and substitute original whole piece driver blade, solved the sawed-off defective of original transmission length of a film needs, whole process is not only safe but also easy.
