CN2374615Y - Improved three-way, five sectional anti-theft lock - Google Patents

Abstract

The utility model relates to a novel improved high-grade three-way five-section theftproof lock which is composed of a base, an upper cover, an inner lock sheet set and a transmission set, wherein the transmission set comprises a driving sheet, a kernel-code lock sheet set, a clamping block, an upper transmission rod, a lower transmission rod, a restoring box and an additional pry-proof top. After a lock sheet is rotated by a key, the lock sheet set generates a passage to make a convex rib on the driving sheet pass, the slide of the driving sheet drives the clamping block to extend forwards to be clamped in a wall, and the pry-proof top butts into the slope side surface of the clamping block. The pry-proof function of the additional pry-proof top is 12.5 times of the pry-proof function of an ordinary lock. The lock can be stably fixed on a door by screws. The utility model has the efficacy of increased safety, theftproof performance and pry-proof performance.

The utility model is made up of base (2), internal lock group (3), loam cake (4) and transmission group (5), internal lock group (3) is installed in the base (2) with transmission group (5), cover with loam cake (4), base (2) is provided with two slide openings (23), slide opening (23) have one with the lockhole (24) of loam cake (4) opposite position, base (2) and loam cake (4) are provided with several screw rods (211) and screw (41).

Internal lock group (3) comprises three keratotic plugs (34), slide plate (31), swivel head (33), spring (35), sliding piece (32) and thimble (37), and slide plate (31) is positioned at three keratotic plugs (34) below.Slide plate (31) is provided with a link stopper (311) and a re-entrant angle (312), locate to be provided with a swivel head (33) at this re-entrant angle (312), this swivel head (33) is provided with one and supports piece (331), when this swivel head (33) sees through knob (39) turn, should support piece (331) and promptly prop up this re-entrant angle (312), thereby make link stopper (311) can block three keratotic plugs (34), it can not be pushed back, and this three keratotic plug (34) is equipped with a spring (35), this spring (35) and base (2) go up set among empty positioning sleeve (36) be connected, when this link stopper (311) when being rotated, and the poke rod (32) that is connected with three keratotic plugs (34) is stirred through an axle bolt (6) insertion, on this moment and the thimble (37) that poke rod (32) touches mutually, because of being with spring (38) when this poke rod (32) moves, be subjected to the opposite direction elastic force of thimble (37) and spring (38), thereby move before and after can driving three keratotic plugs (34), make this bolt (6) even break and be connected to an antitheft axle (61) under this bolt (6), also can make a unlatching by antitheft axle (61) by nationality.

Transmission group (5) is by rotating plate (52), nuclear sign indicating number lock sheet groups (51), stop block (53), upper moveable rod (54), following moving bar (55), return box (57) constitutes with pick-proof top (59), rotating plate (52) is provided with fin (521), following fin (522), double wedge (523) and two convergence holes (524), and this time fin (522) is gone up slide opening (23) fit mutually with base (2), making rotating plate (52) can take this front and back slides, last fin (521) and double wedge (523) and the nuclear sign indicating number lock sheet groups (51) that is contained in rotating plate (52) top action mutually, push rod (531) fit of two convergence holes (524) stop blocks (53) below, on the stop block (53), respectively be provided with a rank bar (532) down, on it, following two drive links (54), (55) strip hole of Shanging (541) fit.This nuclear sign indicating number lock sheet groups (51) is formed with six steel discs again, steel disc is provided with two elliptical apertures (514), lockhole (513) within double wedge within tooth bar is different in size (512) and internal diameter are irregular, when lockhole (513) rotates in key inserts, double wedge (523) also can and then rotate on rotating plate (52) was gone up, make interior double wedge (512) marshalling produce a passage, the last fin (521) of rotating plate (52) be able to by, so drive is linked in the last stop block (53) of rotating plate (52) and releases forward, make simultaneously be linked on the stop block on, following two drive links (54), (55) on, the following extension, and in course of action, being linked in torsion spring (60) on the screw rod (211) of base (2) pushes up pick-proof (59) all the time and is pressed against on stop block (53) side, when stop block (53) when extending to extreme position, pick-proof top (59) is under the power effect of torsion spring (60), rotate around step pin (61), stop block (53) prism is withstood on the top, prevents that the external force sled from hitting the function that stop block causes the stop block retraction and loses locking.Must be again by the rotation of key the pick-proof top is resetted, stop block just can be return.Should engage with top flat group (56) at nuclear sign indicating number lock sheet groups (51) front end protrusion place again, and be connected to spring (58) after this top flat group, spring (58) is packed in the blind cylindrical hole of return box (57), after nuclear sign indicating number lock sheet groups (51) action is finished, the reaction force of nationality top flat group is able to again superimposed, and nationality could repeat above-mentioned action by the rotation of key again.

In sum, after the utility model increases the pick-proof ejection device, improve 12.5 times (up to static pressures of 9800N stop block do not bounce back 8mm) than common lock tamper-resistant function.The lock that makes that can be more firm is fixed on the door, so can avoid being unlocked easily and the quilt anxiety of sled, more can improve the effect of its safe antitheft.
