Description

Code-variable lock of safety door

Technical field the present invention relates to a kind of mechanical lockset

The security door lockset that background technology is present, what its lock core adopted is the yi word pattern lock core, cross lock core, unit's column type lock core etc., the key that is mated, the monodentate type is arranged, cross four toothrow types, the type of digging a pit, hole, etc., the dig a pit, hole, etc. type of combining of flute profile, emboss pit dig a pit, hole, etc. type etc. various, its latter has very big raising than the former anti-theft effect, but because these follow-on lock cores all are the constraints of thoroughly not breaking away from traditional structure pattern (reaching the concordant principle of the discrepancy in elevation, first column type rotational structure), so just inevitably there are many deficiencies of traditional mode structure, thereby caused lockset can't resist the performance drawback that technological means is opened completely effectively, this defective is often utilized by the thief, thereby causes numerous robbed or burgled cases to take place.

The fastening hole code change lock pin that summary of the invention the invention provides the telescopic motion of a kind of square type cooperates the security door lockset of making.It can not only be in full force and effect resist technical means unblank the crime, and the hole clipping coded combination of (several times to tens times) change in the lock core repeatedly, with different key operated separately, prevent to lose or key is joined the generation of the robbed or burgled incident that causes harm that causes steathily by the people because of key, and avoid because of changing lockset, the trouble that the preparation key brings, bothersome.This lock becomes sign indicating number once, just is equivalent to the value of purchasing the result of use of new lock, and more convenient and quicker (approximately time half a minute, promptly finishing the change code operations).

Lock core of the present invention partly, by cell wall plate, moving sheet, coded slice, hole clipping plate, pellet shot from a slingshot plate, lock core tongue, spring saddle, side cover plate, upper cover plate, lower shoe, front shroud, back shroud, be combined into packet.Groove is kept away plate a horizontal half dollar groove, dress half dollar axle in the groove, above liner forms cavity in a narrow margin with following society pad between cell wall plate and hole clipping plate, cavity is half of high half of short, a short packaged moving sheet, a slice coded slice (coded slice that all the other a plurality of coded combinations have nothing in common with each other is done standby) is inserted on high one side a fillet type key socket between hole clipping plate and pellet shot from a slingshot plate, be to be a dead bolt of shoulder type between pellet shot from a slingshot plate and spring saddle, the strip-type hole of dead bolt head from upper cover plate stretches out, lining is propped up by the spring bullet in the lower end, stretching motion up and down, front shroud has the first post tapered end of the weak point that is fixed in the above, and stripe shape key socket is arranged in the tapered end, the pellet shot from a slingshot hole is disorder distribution on the hole clipping board plane, horizontal type passes the pellet shot from a slingshot plate, dead bolt, the spring saddle, identical the communicating of its cloth hole general layout, dress steel ball in the pellet shot from a slingshot hole, pellet shot from a slingshot, microsprings, key is the plane, the plain edge thin slice, front end has irregular distribution through hole, and cloth hole general layout is identical with the part of lock core general layout, irregular aligning.

Lock is originally by lock housing, base plate is formed lock box, the Built-in lock hyoplastron, the bolt plate front end is fixed three first post dead bolts, unit's post dead bolt stretches out from sealed sidewall, but half range is stamped the drive plate of a move left and right on the bolt plate plane, there is a rectangular spring groove drive plate upper end, in adorn a lining left, one serves as a contrast two springs, left and right sides spring to the right, the middle part has rectangular perforation (mouth) lower end that two lining foots are arranged, the lining foot has following convex closure therebetween, and a hold-down screw in the bag, screw pass from bolt plate downwards and be sagging screw, on the half range plane elevator is housed under the bolt plate, the elevator upper edge has two to face upward the lining foot, and there is a vertical inverted triangle convex closure lower edge, and there is return spring at its back side.At drive plate, on the plane of elevator, a top plate that fixes with bolt plate is arranged, the top plate epimere has spring groove, there is rectangular perforation at the middle part, there is a fixing perpendicular screw below, hole, there is the startup hook that can swing on the screw right side, control with microsprings, the fastening hole code change lock pin of below elevator, packing into, lock core tongue upper side is adorned a slide bar, an automatic lock bolt is adorned on the lock core right side, the automatic lock bolt front end stretches out from sealed side, the rear end is fixed by support, and the automatic lock bolt back is automatic tongue foot piece, and spring is housed on the foot piece, the automatic lock bolt back segment has steady rest, there is the long leg that turns the steady rest top, and length turns the leg knuckle first hole, and first hole is through on the slide bar, there is a short straight leg locating rack below, short straight leg is fixed a screw, and screw stretches out from the lock housing back, and a concentric shafts of passing lock housing and base plate is arranged in the lock box upper edge, constitute by half front axle and back semiaxis, there is the fixing preceding drive block that meets at right angles with it half front axle lock box the inner, and there is an arc breach in its stage casing, and hypomere has a big square hole, be enclosed within the perpendicular screw of top plate, the press strip drive block of will going forward is pushed down with starting hook, and half front axle stretches out on the lock box bottom and overlaps one handle.Later half shaft lock box inner segment, one back drive block is housed, and there is the arc breach at its middle part, and hypomere has first hole, the sagging screw of drive plate passes in the hole in unit, sagging screw-tipped is in the centering block Eight characters mouth, and centering block two ends centre bore is enclosed within the lock box central post, and respectively there is one ellipse yuan of hole at the centering block two ends, respectively be enclosed within on left expansion strip and the right expansion strip screw, left side expansion strip stretches out lock box from the lower-left end, and right expansion strip stretches out lock box from upper right side, and the back semiaxis other end stretches out lock box and the section of stretching out goes up the cover one handle.

Because adopted above-mentioned a series of technical scheme, the present invention compares with prior art, and following beneficial effect is arranged.

The mechanical lock master of prior art, have varied, but all can't resist technical means basically opens, make with the cooperation of prior art lock core, rolling screen door lock, safe-guard door lock, the safety cabinet coded lock, automotive lock, electric motor car, bicycle lock etc., can both be opened rapidly with technical means by the robber, thereby cause numerous robbed or burgled incidents to take place, and fastening hole code change lock pin of the present invention, can any technical means of cocksure resistance open, cooperate the above-mentioned lockset made from lock core of the present invention, surely fully technical means are unblanked to do the crime chance of success controls to is zero.
