Description
Technical field
The present invention relates to lockset and manufacture 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 sold in the market is made up of lock box, master lock tongue and double hook dead bolt.Its defect is: the hook lock tongue being contained in master lock tongue both sides the state of stretching out be subject to larger side to power effect or clash into time, hook lock tongue will flexural deformation, and produce during retraction and hinder, impact uses and the pick-proof poor performance of lock.
Summary of the invention
The object of the invention is to: provide a kind of synchronous double hook bolt burglarproof door, when hook lock tongue is subject to larger side to power effect or shock, 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 lock box front portion, the riveted joint of master lock tongue is fixed on master lock hyoplastron, double hook dead bolt is riveted respectively and is fixed on mortise lock hyoplastron, sliding panel and interlock bar are equipped with in 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, side linkage piece is housed, master lock hyoplastron and mortise lock hyoplastron are all controlled by sliding shoe.
The present invention is further characterized in that: double hook dead bolt is built with swing hook, and swing hook is connected with double hook dead bolt by hook axle.
Stumble before the position at double hook dead bolt place is provided with in described lock box motion block and after to stumble motion block, afterbody and the front and back of swing hook stumble motion block contact with the use of.
Described sliding shoe has the rack bore that three shapes are identical, rack bore controls master lock tongue simultaneously and double hook dead bolt stretches out the position of lock box outward or in retraction lock box.
In the middle part of described main linkage plate, swinging axle is housed, swinging axle is connected with lock box.
In the middle part of the linkage piece of described side, swinging axle is housed, swinging axle is connected with lock box.
Principle of the present invention is: during enabling, the shifting block of tapered end rotates to a direction, the pressure that sliding shoe overcomes dress spring thereon moves upward, pin on master lock hyoplastron and upper and lower two mortise lock hyoplastrons disengages with the tooth bar in rack bore respectively, and master lock hyoplastron drives master lock tongue to bounce back in lock box.Pin simultaneously on master lock hyoplastron also drives main linkage plate to swing to a direction around swinging axle, main linkage plate drives interlock bar to move upward, interlock bar drives upper and lower two side linkage pieces to swing to a direction around swinging axle, side linkage piece drives two mortise lock hyoplastrons that double hook dead bolt is pulled in lock box respectively, the afterbody of the swing hook in upper and lower two double hook dead bolts respectively with after stumble after motion block contacts, the swing to retraction direction is produced, together with double hook dead bolt in retraction lock box around hook axle.When locking a door, the shifting block of tapered end rotates to other direction, move upward with the pressure that above-mentioned the same sliding shoe overcomes spring, the pin on master lock hyoplastron and upper and lower two mortise lock hyoplastrons disengages with the tooth bar in rack bore respectively, and master lock hyoplastron drives master lock tongue to stretch out outside lock box.Pin simultaneously on master lock hyoplastron also drives main linkage plate to swing to other direction around swinging axle, main linkage plate drives interlock bar to move downward, interlock bar drives upper and lower two side linkage pieces to swing to other direction around swinging axle, side linkage piece drives two mortise lock hyoplastrons that double hook dead bolt is promoted outside lock box respectively, after the afterbody of the swing hook in upper and lower two double hook dead bolts contacts with motion block of front stumbling respectively, produce the swing of axially stretching out direction around hook, stretch out outside lock box together with double hook dead bolt.
Because the dead bolt that present invention employs master lock tongue and upper and lower two buckles moves and the structure of pinning simultaneously, so anti-theft pick-proof performance is strong.
