Description

A kind of high safety three-row locking cam and key

Technical field: the utility model system is assemblied in a kind of high safety three-row locking cam and the key that places such as safety cabinet, strongbox, silver cabinet and family, hotel, garage need high insurance lockset, belongs to five metals lockset industry.

Background technology: Zhongshan City, Guangdong Province patent inventor Mr. Chen Zhihe applied for two utility model patents continuously on August 6th, 2002, " pellet shot from a slingshot adds the double high insurance safety lock head of T-shape sheet " by name, the patent No. 02272357.9; " the high insurance safety lock head of double angle spoon ", the patent No. is 02272356.0; These two kinds of lock head structure novelties, reasonable in design, stable performance; Make assembling easily, detective in the production; Big, the safety of secret key amount is anti-ly dialled, pick-proof, theftproof performance be good.These two kinds of locksets are at the Delta of the Pearl River, and partly sell, promote in province, city, and benefit is better.But the inventor does not satisfy, and wishing to have on billiards lock structure the more new breakthrough, the utility model come to this, a kind of situation produces.

The utility model content: the purpose of this utility model provides a kind of high safety three-row locking cam and key, and it is to dig three row's pellet shot from a slingshot holes in lock core, and the centre is the sub-hole of buckshot, and both sides are " one " font pellet shot from a slingshot hole, and are equipped with buckshot and " one " font pellet shot from a slingshot; Therewith coupling be high in the middle of one, both sides are low, three row's spoon keys of three row's tartars, the secret key amount is dialled greatly, anti-, pick-proof thereby reach, difficulty is opened, theftproof performance is fabulous.The technical solution of the utility model is to solve like this: invention artificially continues to improve cylinder lock anti-theft security performance, and he digs three row's pellet shot from a slingshot holes audaciously in the lock core side, and centre one row is the sub-hole of buckshot, and both sides two rows are " one " font pellet shot from a slingshot hole.Component location guide pellet shot from a slingshot in the sub-hole of buckshot, assembling " one " font pellet shot from a slingshot peace pellet shot from a slingshot in " one " font pellet shot from a slingshot hole.Because the axial height of buckshot does not have " one " font pellet shot from a slingshot to add the height of both sums of flat pellet shot from a slingshot, therefore, just formed " protruding " font slotted eye at the keyhole groove of lock core front end.Pi Pei key is that height in the middle of, both sides are low, three row's spoon keys of three row's tartars therewith.Then, also dig the flat pellet shot from a slingshot of three rows hole, assemble high and low different flat pellet shot from a slingshot and spring in flat pellet shot from a slingshot hole, at the end assembling bead sealing piece of spring in a side of tapered end.Here, the sub-hole of the buckshot on the lock core and " one " font pellet shot from a slingshot hole are alternately, thus the thickness of attenuate key.High and low different flat pellet shot from a slingshot and spring of assembling on the tapered end, purpose are to make three row's spoons tartar height difference straggly on the key, to increase the secret key amount.Then, be assemblied on the plane, top, flat pellet shot from a slingshot hole with bead sealing piece." one " font pellet shot from a slingshot hole can be provided with 1-12; Peace pellet shot from a slingshot hole, the sub-hole of buckshot also can be provided with 1-12.Therefore, assembling " one " font pellet shot from a slingshot is the 1-12 sheet in " one " font pellet shot from a slingshot hole; Component location guide pellet shot from a slingshot 1-12 is individual in the sub-hole of buckshot; Assembling is flat pellet shot from a slingshot 1-12 in flat pellet shot from a slingshot hole.Characteristics of the present utility model be exactly the cross sections of three row spoon keys are " protruding " shaped sections.From above briefing, the utility model has the advantages that as can be seen: (one) is novel in design, rational in infrastructure; (2) make, assemble easily, detective in the production; (3) the secret key amount is big; (4) theftproof performance is good, anti-dials, pick-proof, anti-robber.

Description of drawings: followingly further specify structure of the present utility model according to accompanying drawing and specific embodiments.

Accompanying drawing 1 is tapered end of the present utility model, lock core component-assembled main body figure;

Accompanying drawing 2 is the upward view of parts key of the present utility model;

Accompanying drawing 3 is the front view of parts key of the present utility model;

Accompanying drawing 4 is the vertical view of parts key of the present utility model.

In the accompanying drawing: 1, tapered end, 2, lock core, 3, buckshot, 4, " one " font pellet shot from a slingshot, 5, flat pellet shot from a slingshot, 6, spring, 7, the sub-hole of buckshot, 8, " one " font pellet shot from a slingshot hole, 9, lock core hole, 10, " protruding " font spoon groove, 11, three row spoon keys, 12, flat pellet shot from a slingshot hole, 13 bead sealing pieces.

Specific embodiments: make component of the present utility model according to the requirement of accompanying drawing, and assemble, just can obtain high safety three-row locking cam and key.Its operational circumstances is such: when three row's spoon keys are released, tapered end is to be in locking states, at this moment, in three row's pellet shot from a slingshot holes, because the impetus of spring 6 is gone in the flat pellet shot from a slingshot 5 of 1 li of tapered end can drop into the pellet shot from a slingshot hole of lock core 2, at this moment can block lock core 2 and tapered end 1, lock core 2 can not be rotated.If putting in plectrum or dial pin outside " protruding " font spoon groove 10 with external force is to be difficult to the flat pellet shot from a slingshot 5 of three rows is transferred to lock core 2, notice, in three row's pellets shot from a slingshot, 15 flat pellets shot from a slingshot have been assembled at present, 15 flat pellets shot from a slingshot are all transferred to lock core 2, its difficulty is well imagined, wants without key---three row's spoon keys---, and is lock core 2 rotations impossible.Therefore, this tapered end 1 is anti-ly dialled, pick-proof, anti-robber's performance be good.When using three row's spoon keys, along with filling in of key, all flat pellets shot from a slingshot 5 are all released lock core 2 by corresponding tartar, in lock core 2, only stay buckshot 3, " one " font pellet shot from a slingshot 4 and the flat pellet shot from a slingshot 5 of assembling in the original lock core 2, therefore tapered end 1 and lock core 2 interconnective interfaces, need only slightly firmly screw key 11 without any obstacle, lock has just been opened, and is very convenient.The utility model is new varieties of cylinder lock, will be subjected to customer's welcome.
