Description

TECHNICAL FIELD

[0001] The utility model relates to door and window accessory technical field, concretely relates to a stable reliable transmission box and door and window thereof. BACKGROUND

[0002] The part provided in this part is merely background information related to the present application to facilitate those skilled in the art to understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] In the door and window lock system, the transmission box plays an important role. The driving mechanism drives the associated lock points to move up and down through the transmission box and cooperates with the lock seat to complete the locking and opening of the door and window. Among them, the patent publication number CN114109140A discloses a novel door and window transmission box device, which comprises a bottom groove plate, two racks are slidably connected on the bottom groove plate, a gear is rotatably connected at the middle position of the bottom groove plate and is meshed with the two racks respectively, a shell seat is assembled on the upper side of the rack and the gear on the bottom groove plate, a shell cover is assembled on the shell seat, the shell seat and the shell cover are combined into a complete box body, a transmission slider is horizontally slidably connected on the lower side of the inside of the box body, and the transmission slider and one of the racks are connected together, and a swing arm is rotatably connected in the inside of the box body. One end of the swing arm is vertically slidably connected on the transmission slider. Thus, when the swing arm is driven to swing, one rack can be driven to move through the transmission of the transmission slider, and the other rack can be driven to move through the meshing of the gear, thereby realizing the reverse sliding of the two racks.

[0004] However, when the above-mentioned transmission box device is used, since there is no any guiding structure between the transmission slider and the box body, when the swing arm swings to drive the transmission slider to slide, the transmission slider is easy to produce deflection, which further causes the rack in transmission cooperation with it to also produce deflection, thereby affecting the transmission effect. In addition, some merchants also rivet the transmission slider and the rack into one body and limit the stable sliding of the rack between the bottom groove plate and the rack, but this way will make the force transmission structure complex, not only easy to cause transmission obstruction, but also need larger driving force, greatly reducing the transmission efficiency.
