Abstract
The utility model relates to a hand-clamping-proof safety door which comprises a door frame and a door board. An upper bearing seat board is fixed at the left upper corner on the inner side of the door frame, a bearing is fixed on the upper bearing seat board in a clearance fit mode, an inner hole of the bearing is in interference fit with an upper rotating shaft to facilitate installation, and the upper rotating shaft is fixed with the top end of the door board. A lower bearing seat board is fixed at the left lower corner on the inner side of the door frame, a bearing is fixed on the lower bearing seat board, an inner hole of the bearing is in interference fit with a lower rotating shaft to facilitate installation, and the lower rotating shaft is fixed with the bottom end of the door board. The cross section at the left end of the door board is an arc face with the upper rotating shaft and the lower rotating shaft as the center, namely hands of a user cannot be injured even the hands are placed at the hinged position of the door board and the door frame.
Description
Technical field
The utility model relates to a kind of door, particularly prevents the safety door of tong.
Background technology
Use at present the structure of door hinged by hinge and doorframe as door-plate.During use, the push-and-pull door-plate namely can be with the door folding.When wrapping the page or leaf rotation, the gap of door-plate and doorframe can change, and normal the appearance squeezed the accident of hindering with children's hand.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of anti-tong safety door, also hand can not squeezed and hinders even hand is placed on door-plate and doorframe hinged place.
The technical scheme in the invention for solving the technical problem is: it comprises doorframe and door-plate, the upper left corner of doorframe inboard is the upper bearing (metal) seat board fixedly, rigid bearing with gap on the upper bearing (metal) seat board, brearing bore and last rotating shaft interference fit, the convenient installation, the top of last rotating shaft and door-plate is fixed; The lower left corner of doorframe inboard is the lower bearing seat board fixedly, rigid bearing on the lower bearing seat board, and brearing bore and lower rotary shaft matched in clearance, the convenient installation, the bottom of lower rotary shaft and door-plate is fixed; The left end cross section of described door-plate is the arc surface centered by above rotating shaft and the lower rotary shaft.
1), simple in structure, easy to install the utlity model has following advantage:; 2), bearing capacity is big, uses indeformable for a long time; 3), rotate door-plate, also hand can not squeezed wound even hand is placed on door-plate with the doorframe hinged place.
