Technical Field

The utility model relates to a transmission lock technical field specifically is a transmission lock.

Background

The existing high-grade casement door and window is generally provided with a transmission lock box to realize opening or closing, the used transmission lock box is generally in an external one-way or external two-way mode, the stress of the one-way transmission lock box in the vertical direction is uneven in the use process, the free end of a window sash is seriously sagged, and the window sash cannot be normally opened after long-time use; two-way transmission lock box is that the outside realizes two-way, does not play the effect of protection lock core to inside transmission can't control two-way bearing motion with the lock core axle, and the time is of a specified duration, produces the damage easily, causes door and window can't close.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a transmission lock to solve current two-way transmission lock box, it is that the outside realizes two-way, does not play the effect of protection lock core, and the motion of the unable two-way bearing of controlling with the lock core axle of inside transmission, the time is of a specified duration, produces easily and damages, causes the unable problem of closing of door and window.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a transmission lock, includes backshell, preceding shell, base, backshell and preceding shell install in the top of base, just the backshell forms the cavity between preceding shell and the base, a serial communication port, the internally mounted of cavity has lock chip piece and tooth piece, tooth has been seted up to the upper end central authorities of lock chip piece, the tooth hole has been seted up at the terminal surface middle part of lock chip piece, the lock dabber is installed to the top of tooth, the backshell with install the locking piece between the preceding shell, the internally mounted of locking piece has the axis of rotation, the internally mounted of axis of rotation has bearing and gear, the gear runs through the tooth hole, the lock dabber includes the flange, the flange with the gear phase-match, the lock dabber is located spacing groove has been seted up to the top both sides of flange.

Furthermore, the inside of backshell is through screw fixed connection with installation piece, the top fixed connection of installation piece has the clamp plate.

Furthermore, pressing sheets are fixedly connected to two sides above the pressing plate.

Furthermore, the rotating shaft and the locking block are both arranged in two, and the rotating shaft and the locking block are both arranged in parallel.

Compared with the prior art, the beneficial effects of the utility model are that:

the internal bidirectional bearing is controlled to transmit through the external single item of the lock core shaft, so that the condition that the lock core is damaged easily due to long time and the door and window cannot be closed is avoided.
