Problems solved by technology
[0002] At present, there are two types of hardware notches for aluminum alloy door and window profiles in the market: U-shaped and C-shaped. The use of aluminum alloy doors and windows originated from the introduction of European aluminum alloy door and window systems. The hardware installation of C-shaped notches relies on the tightening force of stainless steel nails and The clamping force of the stainless steel lining of the machine screw and the hardware notch ensures the firmness of the hardware installation. The tightening of the stainless steel nail will produce a local deformation of about 0.5-1.0 mm on the surface of the profile, so that the stainless steel nail and the aluminum profile are tightly combined to ensure The hardware does not shift when it is stressed; however, when installing doors and windows with C-shaped notches, unnecessary installation errors will occur, which will increase the workload of the operation; therefore, in order to solve the above problems, it is urgent to develop a new C Inward-opening and inward-folding doors and windows with type notch prevent wrong operation mechanism

The invention discloses a novel misoperation prevention mechanism of an inward tilt-turn door / window with a C-shaped notch. The mechanism comprises a lever handle, wherein screw holes are formed in two sides of the lever handle; the lever handle comprises a handle body; a shifting lever sleeves the handle body through a shifting piece; a shifting lever friction block is arranged on the right side of the shifting lever; a raised block is arranged on the left side of the shifting lever; a misoperation prevention device is clamped above the shifting lever through the raised block and is connected with the screw holes in the lever handle through connecting screws; a misoperation prevention device locking seat is fixed on the misoperation prevention device. According to the novel misoperation prevention mechanism of the inward tilt-turn door / window with the C-shaped notch, the whole shell assembling surface is fixed by an inclined surface, a screwing bolt is firm during locking, a sealing rubber strip is not compressed when a clamping block is collided with the misoperation prevention device locking seat, and thus the sealing property of the whole window system is enhanced; a chute and a shifting system are completely combined together and fixed between the lever handle and a section, so that the whole mechanism is attractive in overall appearance and firm.
Description
technical field [0001] The invention belongs to the field of wrong operation preventing mechanism, and in particular relates to a new mechanism for preventing wrong operation of a C-shaped notch opening and falling door and window. Background technique [0002] At present, there are two types of metal notches for aluminum alloy doors and windows in the market: U-shaped and C-shaped. The use of aluminum alloy doors and windows originated from the introduction of European aluminum alloy doors and windows systems. The hardware installation of C-shaped notches relies on the tension force of stainless steel nails and The clamping force of the stainless steel lining of the machine screw and the hardware notch ensures the firmness of the hardware installation. The tightening of the stainless steel nail will produce a local deformation of about 0.5-1.0mm on the surface of the profile, so that the stainless steel nail and the aluminum profile are tightly combined to ensure The hardw...
