Description

Technical Field

[0001] The utility model relates to the technical field of hinges, and in particular to a U-shaped back plate quick-install flat hinge. Background Art

[0002] Nowadays, most residential buildings are high-rise buildings with many high-altitude rotating windows. When installing casement hinges, it is necessary to use a pressure plate for installation and connection. Traditional pressure plates are mostly straight pressure plates, and are shorter than the hinge leaf profiles. As a result, when installing the straight pressure plate, the bottom needs to be supported in the fan profile to prevent the pressure plate from sliding in the fan profile installation groove. It also requires manual alignment and leaf profile holes and threaded holes, and cannot be quickly positioned. It needs to be installed with both hands, which has low installation efficiency. In addition, the straight pressure plate is easy to deform and has low strength. For this reason, we propose a U-shaped back panel quick-install casement hinge. Utility Model Content

[0003] The utility model aims to provide a U-shaped back panel quick-install flat hinge to solve the problems raised in the above-mentioned background technology.

[0005] Preferably, the back plate and the positioning plate are integrally bent and formed, and the back plate and the positioning plate are combined to adopt a U-shaped pressure plate structure.

[0006] Preferably, the threaded hole and the positioning hole are spaced at the same distance from each other, and the threaded hole and the positioning hole are matched with each other.

[0007] Preferably, grooves are formed on two opposite sides of the back plate.

[0008] Preferably, the back plate and the positioning plate are made of stainless steel.

[0009] Beneficial effects: Compared with the prior art, the beneficial effects of the utility model are: through the arrangement of the back plate, the positioning plate, and the positioning holes, the back plate and the positioning plate are integrally formed into a U shape, and 304 stainless steel is used, the structure is more reasonable, and a U-shaped bending process is performed to increase the overall strength, and it can be quickly positioned and installed. The U-shaped pressure plate structure enhances the overall rigidity and strength, increases the impact resistance, is not easy to deform, and break, can be installed more quickly, and quickly positioned, and can be installed conveniently and quickly with one hand, which solves the problem of the traditional straight pressure plate being installed in the fan profile to support the bottom to prevent the pressure plate from sliding in the fan profile installation groove, and requires manual alignment and the problem of the leaf profile hole position and threaded hole, saving time and effort, and having high installation efficiency.
