Description
Technical field
The utility model relates to lockset and makes field, particularly a kind of synchronous double hook bolt burglarproof door.
Background technology
If the double hook dead bolt main lock of safeguard chain door of selling in the market is comprised of lock box, master lock tongue and double hook dead bolt.Its defective is: when the hook lock tongue that is contained in master lock tongue both sides was subject to larger side to power effect or bump at the state of stretching out, the hook lock tongue will flexural deformation, produces during retraction and hinder, and impact is used and the pick-proof poor performance of lock.
Summary of the invention
The purpose of this utility model is: a kind of synchronous double hook bolt burglarproof door is provided, and when the hook lock tongue was subject to larger side to power effect or bump, dead bolt can not produce flexural deformation, and the anti-theft pick-proof performance of lock is strong.
A kind of synchronous double hook bolt burglarproof door, master lock tongue and double hook dead bolt are equipped with in the lock box front portion, the riveted joint of master lock tongue is fixed on the master lock hyoplastron, the double hook dead bolt is riveted respectively and is fixed on the mortise lock hyoplastron, sliding panel and interlock bar are equipped with in the rear portion, it is characterized in that: between described master lock hyoplastron and interlock bar main linkage plate is housed, between mortise lock hyoplastron and interlock bar the side linkage piece is housed, master lock hyoplastron and mortise lock hyoplastron all are controlled by sliding shoe.
The utility model is further characterized in that: the double hook dead bolt is in-built swing hook, and swing hook links to each other with the double hook dead bolt by the hook axle.
Stumble before being provided with near the position at double hook dead bolt place in the described lock box motion block and after the motion block of stumbling, the afterbody of swing hook and the front and back motion block of stumbling contacts and is used in conjunction with.
Have three rack bore that shape is identical on the described sliding shoe, rack bore is controlling simultaneously the master lock tongue and the double hook dead bolt stretches out the position that lock box is outer or the retraction lock box is interior.
Swinging axle is equipped with at described main linkage plate middle part, and swinging axle links to each other with lock box.
Swinging axle is equipped with at described side linkage piece middle part, and swinging axle links to each other with lock box.
Principle of the present utility model is: when opening the door, the shifting block of tapered end rotates to a direction, the pressure that sliding shoe overcomes dress spring thereon moves upward, the master lock hyoplastron and up and down the pin on two mortise lock hyoplastrons respectively with rack bore in tooth bar disengage, the master lock hyoplastron drives the master lock tongue and bounces back in lock box.Pin on the while master lock hyoplastron also drives main linkage plate and swings to a direction around swinging axle, main linkage plate drives the interlock bar and moves upward, the interlock bar drives up and down, and two side linkage pieces swing to a direction around swinging axle, the side linkage piece drives respectively two mortise lock hyoplastrons the double hook dead bolt is spurred in lock box, up and down the afterbody of the swing hook in two double hook dead bolts respectively with after stumble after motion block contacts, produce swing to retraction direction around the hook axle, and the double hook dead bolt is retracted together in the lock box.When locking a door, the shifting block of tapered end rotates to other direction, the pressure that overcomes spring with above-mentioned the same sliding shoe moves upward, the master lock hyoplastron and up and down the pin on two mortise lock hyoplastrons respectively with rack bore in tooth bar disengage, the master lock hyoplastron drives the master lock tongue and stretches out outside lock box.Pin on the while master lock hyoplastron also drives main linkage plate and swings to other direction around swinging axle, main linkage plate drives the interlock bar and moves downward, the interlock bar drives up and down, and two side linkage pieces swing to other direction around swinging axle, the side linkage piece drives respectively two mortise lock hyoplastrons the double hook dead bolt is promoted outside lock box, the afterbody of the swing hook in two double hook dead bolts is respectively with after the motion block of front stumbling contacts up and down, the swing of direction is axially stretched out in generation around hook, and the double hook dead bolt stretches out outside the lock box together.
Because the utility model has adopted master lock tongue and the dead bolt of two buckles structure of moving simultaneously and pinning up and down, so the anti-theft pick-proof performance is strong.
