Abstract
The invention discloses a D-shaped antitheft lock. The technical scheme disclosed by the invention has the key points that the D-shaped antitheft lock comprises a tubular straight shank and a U-shaped lock ring; a pinhole is arranged at one end of the U-shaped lock ring and is riveted with a U-shaped part at one end of the tubular straight shank by a hinge pin to form an outer hinge; the tubular straight shank is hollow; both ends of the inner wall of a cavity of the tubular straight shank are respectively provided with one round tube; a lock cylinder of an elastic lock is clamped between the two round tubes; the front end of the lock cylinder is provided with an eccentric shaft; a bolt in the lock cylinder is clamped with a lock bar to complete a locking state; a round steel sheet is added on the end face of a keyhole of the lock cylinder; a steel ball can be added on the joint face of the round steel sheet and the lock cylinder to form a pressure bearing; and the lock cylinder is arranged at the middle part of the tubular straight shank. According to the invention, the condition that the end face of an opening is knocked by force to ensure the bolt to fall down so that the antitheft lock is unlocked can be effectively prevented; and moreover, the lock cylinder of the D-shaped antitheft lock is arranged at the middle part of the tubular straight shank, so that the D-shaped antitheft lock takes good effects of preventing the D-shaped antitheft lock from being technically unlocked and preventing the lock cylinder from being broken by an electric drill.
Description
Technical field
The present invention relates to lock field, particularly a kind of D type theftproof lock of theftproof performance excellence.
Background technology
Popular D type lock one end is hinge in the market, and other end opening, the groove on the lock ring of opening one end is blocked by dead bolt the process of locking that completes.But use such lockset, knock by force opening part end face and be easy to make dead bolt to fall piece and cause theftproof lock to be opened.And keyhole is located at opening part one end, adopt technological means to open and be also easy to, adopt in addition electric drill that lock core is broken also and lock can be opened.The insurance theftproof performance of the D type theftproof lock therefore using is at present poor.
Summary of the invention
The D type theftproof lock that the object of this invention is to provide a kind of theftproof performance excellence, it had both been not easy to be torn down by violence, was difficult to again adopt technology unlocking means to open it.
Technical scheme of the present invention completes as follows, and a kind of D type theftproof lock, comprises tubulose staight shank and U-shape lock ring, it is characterized in that: one end of described U-shape lock ring has a pin-and-hole to form outer hinge by the U-shaped portion part riveted joint of bearing pin and tubulose staight shank one end; Described tubulose staight shank is hollow, a pipe is respectively equipped with at its cavity inner wall two ends, and between two pipes, card has the lock core of a cylinder lock, and lock core front end has an eccentric shaft, the dead bolt coordinating with bias blocks locking bar and completes locking state, and lock core is located at the middle part of tubulose staight shank; A side at lock core keyhole is equipped with key extension bar, and one end of this key extension bar is provided with key draw-in groove, and sidewall has two grooves, and they become 90 degree to intersect; The outer end of described locking bar is a circular flat, concordant with tubulose staight shank one end when circular flat locking, plane is connected with the round bar of cross section one-tenth step, middle thicker part position is provided with sliding recess, the locking bar of lockset in enable possition can not be transferred to and depart from lock body, there is a groove at thinner position, and the openings of sizes of groove matches with dead bolt, and the distal end faces at thinner position is inclined-plane; The afterbody of described U-shaped shackle openings one end is provided with penetrating hole, and the openings of sizes in this penetrating hole is consistent with the diameter of thicker part position in the middle of locking bar.D type theftproof lock of the present invention, is characterized in that: the keyhole end face of described lock core is added with a circular steel disc, and this circle steel disc and lock core mating face can add steel ball mineralization pressure bearing.
The present invention can prevent that knocking by force opening part end face makes dead bolt fall piece and cause theftproof lock to be opened effectively, because locking bar interts in the penetrating hole of U-shape lock ring one end, blocked by dead bolt at the other end, violence orcible entry makes dead bolt fall piece to cause theftproof lock to be opened unlikely like this; Lock core of the present invention is placed in the middle part of tubulose staight shank in addition, to preventing that technology unlocking and electric drill from breaking lock core and having played good effect, has greatly increased the theftproof performance of such lockset.

Detailed description of the invention
Describe by reference to the accompanying drawings embodiment in detail.A kind of D type theftproof lock, comprises tubulose staight shank 1 and U-shape lock ring 2, and one end of U-shape lock ring 2 has a pin-and-hole to be riveted and formed outer hinge by the U-shaped portion part 3 of bearing pin and tubulose staight shank 1 one end; Tubulose staight shank 1 is hollow, pipe 11 and pipe 12 are equipped with respectively in its cavity inner wall two ends, between pipe 11 and pipe 12, card has the lock core 4 of a cylinder lock, lock core 4 front ends have an eccentric shaft, block locking bar 6 with the supporting dead bolt 5 of eccentric shaft and complete locking state, lock core 4 keyhole end faces can separately add a circular steel disc 8, and this circle steel disc 8 can add steel ball 9 mineralization pressure bearings with lock core 4 mating faces, and lock core 4 is located at the middle part of tubulose staight shank 1; A side at lock core 4 keyholes is equipped with key extension bar 10, and one end of this key extension bar 10 is provided with key draw-in groove, and sidewall has two grooves, and they become 90 degree to intersect; The outer end of described locking bar 6 is circular flats, concordant with tubulose staight shank 1 one end when circular flat locking, plane is connected with the round bar of cross section one-tenth step, middle thicker part position is provided with sliding recess, the locking bar 6 of lockset in enable possition can not be transferred to and depart from lock body, there is a groove at thinner position, and the openings of sizes of groove matches with dead bolt 5, and the distal end faces at thinner position is inclined-plane; The afterbody of described U-shape lock ring 2 opening one end is provided with penetrating hole, and its openings of sizes is consistent with the diameter of thicker part position in the middle of locking bar 6.D type theftproof lock is in the time of locking state, and while inserting the rear rotation of key 7, eccentric shaft can be pushed the dead bolt 5 that is pressed in locking states by spring aside, and locking bar 6 is ejected by one end spring, and D type theftproof lock can be opened.
For preventing technology unlocking, lock core 4 is located at the middle part of tubulose staight shank 1, key 7 must be furnished with key extension bar 10 and could insert in lock core 4, such design has increased very large difficulty to technology unlocking, one end of key extension bar 10 is provided with key draw-in groove, and it can be clamped on key 7 front end of extension bar.Key 7 also can convenient taking-up after locking simultaneously.For ensureing that key 7 can accurately insert in lock core 4 keyholes, and can do 90 degree Unscrew dead bolts 5.On key extension bar 10, have two grooves, their types that meets at right angles intersect.
For preventing violence orcible entry, the groove of conventional U-shape lock ring one end is coordinated with dead bolt and makes locking bar 6 into and intert in the penetrating hole of U-shape lock ring 2 one end, violence tears down unlikely like this.When locking, can complete locking state as long as press locking bar 6 outer surface levels with finger.
For preventing with electric drill, lock core 4 being broken lock is opened, lock core 4 end faces separately add a circular steel disc 8, and steel disc and lock core 5 mating faces can add steel ball 9 mineralization pressure bearings, if while wanting like this to break lock core 4 with electric drill, circular steel disc 8 can dally, thereby lock core 4 cannot be broken.
