Embodiment Construction

[0018] Such as figure 1 As shown, one side of the door / window body 1 is hinged on the door / window frame, and the upper and lower parts of the end surface on the other side are provided with an inwardly recessed accommodation cavity 2, which is used to store the wedge 3 and the laser transmitter 9 or laser receiver 10, its size packaging can not interfere with wedge 3 and laser transmitter 9 or laser receiver 10.

[0019] The bottom end of the accommodation chamber 2 is provided with a spring groove 4 extending inward, the spring groove 4 is perpendicular to the accommodation chamber 2, and the return spring 5 is fixed in the spring groove 4, and one end of the return spring 5 is fixed on the bottom end of the spring groove 4, and the other end is Fixed on the wedge 3, the return spring 5 pushes the wedge 3 and the laser emitter 9 or the laser receiver 10 out of the accommodation cavity 2 when the force is not applied (released).

[0020] Wedge 3 is an anti-pinch stopper that ...

Abstract

The invention discloses a door and window anti-pinching device. One side of a door / window body is hinged to a door / window frame, accommodating cavities which are recessed inwards are separately formedin the upper portion and the lower portion of the end surface of the other side of the door / window body, a spring groove which extends inwards is formed in the bottom end of each accommodating cavity, a return spring is fixed in each spring groove, one end of each return spring is fixed at the bottom end of each spring groove while the other end is fixedly connected to a wedge block, an inclinedplane of each wedge block faces the door / window frame, a laser transmitter and a laser receiver which cooperate with each other are arranged on opposite end surfaces of the two wedge blocks which arepositioned on the upper portion and the lower portion of the door / window body; a rack groove which extends inwards is formed in the bottom end of the accommodating cavity which is positioned on the upper portion and / or the lower portion of the door / window body; a locking mechanism which is used for locking a rack is arranged beside the rack groove; and an end of the rack is fixedly connected to the wedge blocks. Whether a barrier exists nearby a door / window or not is judged by a sensor, therefore, human hands are prevented from being pinched effectively, functions are humanized, and the door and window anti-pinching device is quite practical.

Description

technical field [0001] The invention relates to the anti-pinch field, in particular to the anti-pinch technology for doors and windows. Background technique [0002] At present, there are many kinds of doors and windows on the market, including push-pull, flat-opening, inward-opening and inverting, folding, pull-up, and fixed. A device to prevent accidental pinching of hands. In our daily life, adults are sometimes caught by doors and windows without paying attention, and children are more vulnerable because they have not yet formed a sense of danger. Aiming at the current shortage, we have developed a door and window anti-pinch device, which installs photoelectric sensors and laser emitters (tentative far-infrared frequency) on the top and bottom of the doors and windows. If it is blocked, the top or bottom baffle device will pop out of the baffle quickly and trigger the alarm at the same time. The alarm sound can remind parents that the child may be in danger, and many a...
