Window shutter and production process thereof

Abstract

The invention belongs to the field of window shutters, and provides a window shutter and a production process thereof. The window shutter comprises a window frame and a plurality of blades; the windowframe comprises a pair of supporting rods and a pair of connecting rods; sectional materials are arranged in the supporting rods; the sectional materials on one or more sides are internally providedwith rails used for fixing racks, the sectional materials on one or more sides are internally provided with the racks, and the racks can slide in the rails in the rail length direction; the supportingrods and the connecting rods are spliced to form a window part, and the multiple blades are mounted in the window part; end shafts are arranged on the blades correspondingly, and the blades are erected on the supporting rods through the end shafts and can rotate along with the end shafts; gears engaged with the racks are mounted on the end shafts on the side provided with the racks correspondingly; and the multiple blades rotate in a linkage mode under the effect of external force. The window shutter is simple in structure, simple in manufacturing step, low in manufacturing cost, free of redundant parts in appearance, convenient to mount and attractive in appearance.

Description

technical field [0001] The invention belongs to the field of windows, relates to the field of shutters, in particular to a shutter and a production process thereof. Background technique [0002] With the increase of the scope of application of shutters, there are also thick shutters used in basements, outdoors or livestock places on the market. This type of shutter blades has fewer and thicker blades, and the design also eliminates complicated pulling mechanisms. , you only need to move one of the blades, and the other blades can be linked. This kind of blinds is equipped with a linkage mechanism inside the window frame, which is generally a connecting rod or a rack. Compared with the connecting rod, the rack is easy to assemble, simpler in structure, less prone to failure, and will not affect the overall appearance of the blinds . [0003] However, the thick shutters currently on the market have the following problems: 1. Due to the complicated production steps, the produ...

AI Technical Summary

Problems solved by technology

[0003] However, the thick shutters currently on the market have the following problems: 1. Due to the complicated production steps, the production cost of the shutters is relatively high; 3. Only part of the rack is fixed on the window frame, which is prone to problems such as rack falling off and bending of the rack, which affects the simultaneous linkage of the blades; 4. The assembly surface of the rack is prone to overshoot during assembly. High, uneven assembly surface, the teeth of the rack on the assembly surface cannot be aligned, and the assembly is prone to failure, etc. When the gear slides to the assembly surface, it is prone to jamming and loosening
