Abstract
The utility model discloses a multipurpose anti-theft concealed cylinder lock for a single door or a double door, which can be unlocked by two different keys simultaneously and can be automatically locked. The multipurpose anti-theft concealed cylinder lock for a single door or a double door is mainly composed of a front and a back lock casings, two lock cores respectively installed on the front and the back lock casings, and a T-shaped clamping pin which is installed in the back casing lock; the front end of the T-shaped clamping pin is provided with a transverse square through hole. After the clamping pin is pushed into the front lock casing by a connecting rod in the back casing, square stops installed on the left and the right sides of the front lock casing can go into the square hole on the front end of the clamping pin, and the front and the back lock casings are connected into one body; when the multipurpose anti-theft concealed cylinder lock for a single door or a double door is unlocked, the front lock core is rotated by a front key, and the front core axle can be rotated by a shifting block; thus, a metal line penetrating through the central hole of the front core axle can drive a shifting bar to enable the stops to be withdrawn from the square hole on the front end of the clamping pin; then, the back lock core is driven by a back key, the back core axle can be rotated by the shifting block, the back core axle can drive a connecting rod to enable the clamping pin to be withdrawn from the front lock casing, and the lock is unlocked. So the utility model is a high-grade anti-theft concealed cylinder lock.
Description
The utility model is a kind of improved, and the single double door that must just can open with two keys simultaneously is many with senior anti-theft billiards built-in lock.
The consistent door lock that uses of people mostly is various forms of padlocks, and such lock is easy to use.For improving antitheft coefficient, people strengthen the volume of lock gradually.But it is, therefore also destroyed easily because of it must be installed in the outside of door.Then people bring into use the theftproof lock as good icepro 115 types, and it is not reach antitheft purpose in the preceding lock housing on being positioned on doorframe by two dead bolts of back lock housing release that are installed on the door, and can inside and outsidely open again.But it can only be used to lock single door, and these built-in locks have only a lock core, so the success rate of bitting is slightly high.
The purpose of this utility model is to provide a kind of improved, not only can open inside and outside lock is during single double door, and must be simultaneously just can open with two keys, anti-theft billiards built-in lock that can automatic blocking.
Task of the present utility model is finished like this, it is made up of preceding lock housing and back lock housing two large divisions, there is in the lock housing one can not sell by connecting rod along " T " font that lead moves forward and backward and link to each other in the back, do not sell front end 1/5th places and have a horizontal square through hole with the rear lock core axle.Both sides are separately installed with handle and lock core inside and outside the lock housing of back, handle can directly be stirred the back mandrel, when using key rotation lock core, the mandrel drivening rod will not sold and pushed in the preceding lock housing after lock core is just stirred by pulling block, in preceding lock housing, have two rectangle blocks enter under can promotion not by the spring of fixing it Xiao square hole in, the front and back lock housing is linked together, both sides also are separately installed with handle and lock core inside and outside preceding lock housing, handle can directly drive preceding mandrel, when stirring lock core with key, mandrel rotated before lock core drove, be installed with a metal line in the hole in the middle of preceding mandrel, its two ends are connected to the end that the left and right sides " " font is pulled out bar, the other end that pulls out bar is fixed on the rectangle block by bearing pin, pulling out bar can its middle bearing pin be that the center swings back and forth, when current mandrel rotates, wire bends, it just spurs two ends of eradicating bar and moves in the middle of lock housing, the other end that pulls out bar then drives block to lock housing two side shiftings, the rectangle block just withdraws from the square hole that " T " font do not sell like this, does not make and Xiao withdraw from preceding lock housing.After being retracted into fully under the drive of not selling at connecting rod after the lock housing, the control pin that is installed in back lock housing handle one side front end just enters in the pit of not selling front end under the promotion of the compression spring on it, will not sell to be controlled at afterwards in the lock housing.When locking a door, the collision block that is connected with the control pin just in time hits on preceding lock housing, because of the parallel lock of lock housing before and after having only can be locked, collision block just will be controlled pin to pusher like this, make it withdraw from not Xiao pit in, Xiao just under the compression spring on its lead of control promotes, not enter preceding lock housing, finish the task of locking a door automatically.
The utility model adopts twin-lock core control structure, though it has just increased a lock core than former theftproof lock, it must use two different keys lock could be opened simultaneously.Therefore and the front and back lock housing all is installed in the inboard of door, improved antitheft coefficient greatly.It not only is applicable to single door, also must just can be not together with two fan door locks with any attached assistant engineer's tool, and can inside and outside open.And Shi Buxu more just can automatic blocking with key or handle locking a door.Other 4 pin front ends adopt forward type, have reduced the technology of processing water chestnut.And after lock is opened, the control pin just will not sold automatically and will be controlled in the lock housing of back, and being stranded this is a kind of door lock of safe ready.
