Description

Dull and stereotyped locking cam of a kind of high safety three-row pellet shot from a slingshot and key

Technical field: the utility model relates to a kind of five metals lockset, and more particularly, it relates to dull and stereotyped locking cam of a kind of high safety three-row pellet shot from a slingshot and key.

Background technology: Zhongshan City, Guangdong Province patent applicant Chen Zhi and be born in December, 2004 earlier and applied for utility model patent, " high safety three-row locking cam and key " by name, the patent No. is 200420102222.6.This lock is reasonable in design, and is easy to make, and the secret key amount is big, antitheft, the pick-proof performance is good, but the pellet shot from a slingshot hole all in a side, and key can only be unblanked in unidirectional insertion, therefore, the utility model is to have done further improvement on the basis of this lock, on the structure of lock bigger breakthrough has been arranged.

The utility model content: the purpose of this utility model is in order to overcome the deficiency of prior art problem, provide a kind of rational in infrastructure, stable performance, safety, three row's pellets shot from a slingshot are at homonymy, dull and stereotyped locking cam of the high safety three-row pellet shot from a slingshot that key can two-way insertion be unblanked and key.

The utility model is to adopt following technical scheme to realize above-mentioned purpose.Dull and stereotyped locking cam of a kind of high safety three-row pellet shot from a slingshot and key, comprise key groove hole, the sub-hole of buckshot, taper buckshot, buckshot, marble spring and go up the sub-hole of buckshot that it is to dig in lock core one side relative with the sub-hole of buckshot eccentric band flange pellet shot from a slingshot hole to be arranged and connect the eccentric band flange pellet shot from a slingshot therein; Distolateral cutting at key groove hole has side pellet shot from a slingshot hole and connects the side pellet shot from a slingshot therein; In tapered end, dig the cone tank that has with side pellet shot from a slingshot hole end surface coupling.Described eccentric band flange pellet shot from a slingshot is provided with eccentric band flange pellet shot from a slingshot head and flange above it.Eccentric band flange pellet shot from a slingshot head is arranged on the interior point of contact of eccentric band flange pellet shot from a slingshot end face circle, and several eccentric band flange pellets shot from a slingshot are arranged in rows, and the eccentric band flange pellet shot from a slingshot head on their end faces is not point-blank.Flange is located on the sidewall of eccentric band flange pellet shot from a slingshot, is to be used for fixing the eccentric band flange pellet shot from a slingshot, prevents that it from rotating.The two ends of described side pellet shot from a slingshot are that cone, centre are cylinder.Have eccentric band flange bullet groove, side pellet shot from a slingshot tartar hole and the taper buckshot pilot trench hole of mating respectively with eccentric band flange pellet shot from a slingshot, side pellet shot from a slingshot, taper buckshot on the dull and stereotyped spoon of three rows, wherein the eccentric band flange bullet groove can be dug waviness.Upper side, downside at the dull and stereotyped spoon of three rows are equipped with the eccentric band flange bullet groove, on eccentric band flange bullet groove side taper buckshot pilot trench hole is arranged, in the left side, the right side is provided with side pellet shot from a slingshot tartar hole, therefore, when unblanking, people can not consider the direction that puts in of key, as long as insert key in the horizontal direction, can unblank.Upside and downside at tapered end also respectively have the flat pellet shot from a slingshot of row hole, are furnished with high and low different flat pellet shot from a slingshot and marble spring in the flat pellet shot from a slingshot of upside hole, then at the top in flat pellet shot from a slingshot hole assembling bead sealing piece.Lock core side assembling side pellet shot from a slingshot, the tapered end downside be equipped with on flat pellet shot from a slingshot and marble spring, the eccentric band flange pellet shot from a slingshot the setting of eccentric band flange head not point-blank, these all are in order to strengthen the secret key amount on original basis, reach anti-and dial, pick-proof, effect that theftproof performance is good.The utility model has the advantages that: (one) novel structure, reasonable in design, easy to make; (2) the secret key amount is big, and is antitheft, the pick-proof performance is good; (3) bigger breakthrough has been arranged on the structure of cylinder lock, the pellet shot from a slingshot hole is not in a side, and key energy two-way unlocking is unblanked conveniently; (4) be adapted at strongbox, safety cabinet, use in places such as family.
