Description
Technical field
The present invention relates to a kind of door lock, especially relate to a kind of sliding door hook lock for sliding door.
Background technology
Existing sliding door hook lock is all single hook structure conventionally, likely skids off and depart from single hook when sliding door is lifted; In addition, once the installation of sliding door hook lock, be fixed up the position of latch hook, if the gap of sliding door and doorframe is larger, can cause latch hook to be combined with locking plate not tight, affects the locking effect of sliding door hook lock.Therefore there is the deficiency in certain safety in existing sliding door hook lock.
Summary of the invention
Technical problem to be solved by this invention is: for the deficiencies in the prior art, provide a kind of safe and reliable sliding door hook lock.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of sliding door hook lock, comprise lock housing and be arranged on latch hook and the locking hook transmission mechanism in described lock housing, described latch hook is connected with described locking hook transmission mechanism, described latch hook comprises symmetrically arranged the first latch hook and the second latch hook, in described lock housing, be provided with for regulating the governor motion of the installation site of described latch hook, when unblanking or locking, under the drive of locking hook transmission mechanism, the direction of motion of the first latch hook and the second latch hook is contrary.
Described locking hook transmission mechanism comprises the first wheel of interlock, the second wheel hub, first connecting rod, second connecting rod and third connecting rod, described first wheel and/or the second described wheel hub are provided with the jack for key inserts or door handle is installed, described lock housing comprises base and cover plate, described cover plate is provided with first circular hole corresponding with described jack, described first wheel is connected by described second connecting rod with the second described wheel hub, the first described latch hook, first connecting rod is connected successively with first wheel, the second described wheel hub, third connecting rod is connected successively with the second latch hook, the junction of the first described latch hook and described first connecting rod is near the back side of the first described latch hook, the junction of the second described latch hook and described third connecting rod is near the front of the second described latch hook.The setting of the locking hook transmission mechanism of interlock, simple in structure, easy to use.During use, clockwise direction rotates key or door handle, the first latch hook clockwise rotates and stretches out in lock housing under the pulling of first connecting rod, the second latch hook rotates counterclockwise and stretches out in lock housing under the promotion of third connecting rod, and the first latch hook stretching out in lock housing and the second latch hook are interlocked with the locking plate being arranged on doorframe respectively again.
Described governor motion comprises symmetrically arranged two groups of adjusting parts, adjusting part described in every group comprises adjustment screw, adjust nut, the first adjustment block and the second adjustment block, described adjustment screw is arranged in described lock housing, described adjustment nut is fixed on described adjustment screw, the first described adjustment block and the second adjustment block are screwed post and the screw that matches with described screw fixed leg is fixed on described housing, the first described adjustment block is provided with the first breach, the second described adjustment block is provided with the second breach, in the first breach described in described adjustment nut is arranged in and the second described breach, the first adjustment block and the second adjustment block that the first described latch hook and the second described latch hook are coupling on one group of adjusting part by rotating shaft respectively, on described base and described cover plate, be respectively arranged with the elliptical aperture matching with described rotating shaft.In the installation process of existing sliding door hook lock in sliding door, the position of latch hook cannot be adjusted, the optimum Match that is difficult to realize latch hook and is arranged on the locking plate on doorframe, the combination defective tightness that causes latch hook and locking plate, affect the locking effect of sliding door hook lock, but in sliding door hook lock of the present invention, the setting of governor motion can address this problem.During installation, look gap length between sliding door and doorframe, screw is adjusted in rotatable adjusting, in adjustment process, being fixed on the adjustment nut of adjusting on screw moves left and right with adjusting screw, owing to adjusting nut, be arranged in the first breach and the second breach in the second adjustment block in the first adjustment block, the first adjustment block and the second adjustment block and the first latch hook and the second latch hook are coupling, adjusting under the drive of nut like this, the first latch hook or the second latch hook also can move left and right, and then can adjust the installation site of the first latch hook and the second latch hook.
