Analysis: Summary of knowledge of inner flat flip hardware for plastic doors and windows

1. The composition of the inner flat flip hardware

It is composed of transmission lock, steering angle, upper suspension part, lower angle part, suspension lock piece, lock block, upper and lower hinges and middle lock.

Two, the working principle of the inner flat flip hardware

The standard handle is horizontally opened. Rotate upwards by 90°, the handle square shaft drives the gear, and the gear drives the sliding plate, the steering angle spring sheet, the upper suspension sliding plate, and the lower angle component pin plate in the transmission through the rack and pinion transmission to move down in turn, so that it is inserted into the suspension pin block In the middle [hanging lock piece], each lock nail is separated from the lock block in turn to complete the upper hanging opening function. One after the other, the handle is rotated 180° downward or 90° in the flat state. The sliding parts of the actuator sliding plate, upper suspension sliding plate, upper and lower corner components drive each lock pin to move upward in turn, and the pin and the pin fixed on the frame Block blocks to realize the locking operation. If anti-theft is required, it can be realized by adjusting the shape of the lock nail and the lock block.

Three, adjustment method

1. The width adjustment is adjusted by the threaded pipe in the upper suspension part and the lower hinge connecting screw, and the adjustment amount is ±2mm.

2. The height adjustment of the window sash is realized by the lower hinge adjustment screw, and the adjustment amount is ±2mm.

3. The airtightness adjustment of window frame and window sash is adjusted by the eccentricity of eccentric locking nail, and the adjustment amount is ±0.9mm.

Four, installation requirements

The upper hinge support is fixed on the steel lining of the window frame by means of a master model with self-tapping nails, and is connected with the upper hinge through the upper hinge shaft, and the upper hinge is connected with the upper suspension part. The upper suspension parts, upper corner parts, actuators, and lower corner parts are respectively fixed on the steel lining of the window sash, the lower hinge support is fixed in the steel lining of the window frame by means of a model, the lock block and the suspension lock piece are respectively fixed on the window frame, The standard handle square pin is inserted into the square hole of the actuator, and the standard handle is connected with the actuator with screws to complete the installation.

This hardware component can be used in a variety of profiles of 12/20-9 and 12/20-13 specifications of the single-opening or half-opening 60 series with 16.22.5 hardware slots.

Fifth, choice

Requirements

If FB≥1300, a second diagonal tie rod and intermediate locking point should be added.

If FH≥1200, the middle lock point (single point or two points) should be added.

For the sake of installation, an anti-error and anti-drop device can be installed, and an anti-flat setting or a handle with a lock can also be added.

VI. Functions and scope of application

After installing the window, you can choose whether to open it horizontally or turn it over.

The flip function allows the room to enter a proper amount of new air, which not only saves space, but also prevents theft.

Swing function: Large amounts of air can enter the room and it is convenient to wipe the glass.

Locking function: meet the performance requirements of heat preservation, energy saving, sound insulation, daylighting and so on.
