Description
Technical field
The present invention relates to a kind of Door for building, relate in particular to a kind of Novel anti-pinch door.
Background technology
The door that uses in the existing building, utilized hinge that door and doorframe are linked together, door-plate and doorframe edge at gemel connection, basically be that protrusion corner angle and spill corner angle cooperatively interact, when opening the door, it is large that the angle that forms between the door limit at hinge place and the doorframe just becomes, and at closing time, the angle at hinge place from large to small.A lot of people particularly in school and other people occasion how, the defective that finger is crushed easily often occurs at closing time.For solving the problem of above-mentioned existence, the patent No. is the safety door that the Chinese invention patent of ZL 200820045373.0 discloses a kind of preventing damage hand, this safety door, door-plate is installed on the doorframe by hinge, crack between a door and its frame couples together by flexible curtain volume between doorframe and the door-plate, and the material of curtain is canvas or nylon cloth; When door was opened, curtain was drawn out from the curtain volume, and curtain blocks the crack between a door and its frame that opens, and when door was shut, curtain blocked the crack between a door and its frame that closes up, and prevented that finger from being crushed.Prevent from pointing the technical problem that is crushed although adopt this technical scheme to solve, but use in public places such as school, hospitals, this safety component that prevents tong suffers that easily cutter is drawn, burning hot damage, can not guarantee safety comprehensively, the probability that later stage needs repairing is large, can not well be applicable to the public arena, more can not limit simultaneously the maximum angle that door is opened.
Summary of the invention
What a kind of Novel anti-pinch door provided by the present invention will solve is to suffer that for the above-mentioned safety component of the safety door of tong that prevents cutter is drawn, burning hot easy damage, the probability that later stage needs repairing is large, can not well be applicable to the defective of public arena, provide a kind of more durable, the probability of later period maintenance is little, more is applicable to a kind of Novel anti-pinch door of the public arena uses such as school.
The scheme that the present invention solves its technical problem is: a kind of Novel anti-pinch door comprises door-plate, doorframe, also include revolving joint, described revolving joint includes fan-shaped door-plate connecting box that metal sheet makes and fan-shaped doorframe connecting box, wherein, the left side of fan-shaped door-plate connecting box is provided with the door-plate brace that sheet metal is made, the door-plate brace is connected with door-plate, and the right of fan-shaped doorframe connecting box is provided with the doorframe brace that sheet metal is made, and the doorframe brace is connected with doorframe; Fan-shaped door-plate connecting box and fan-shaped doorframe connecting box seal fit mutually; When door-plate cuts out, the fan-shaped part of fan-shaped door-plate connecting box screws in the fan-shaped part of fan-shaped doorframe connecting box, when door-plate is opened, the fan-shaped part of fan-shaped door-plate connecting box screws out the fan-shaped part of fan-shaped doorframe connecting box, and the fan-shaped radian of described fan-shaped door-plate connecting box equals the fan-shaped radian of fan-shaped doorframe connecting box.
Adopt a kind of Novel anti-pinch door of technique scheme, owing to be provided with revolving joint, this revolving joint is made by metal sheet, the curtain that relatively uses in the prior art scheme, exist durable, the advantage that the probability of later period maintenance is little; And, because fan-shaped door-plate connecting box and fan-shaped doorframe connecting box seal fit mutually, when door-plate cuts out, the fan-shaped part of fan-shaped door-plate connecting box screws in the fan-shaped part of fan-shaped doorframe connecting box, when door-plate is opened, the fan-shaped part of fan-shaped door-plate connecting box screws out the fan-shaped part of fan-shaped doorframe connecting box, the fan-shaped radian of described fan-shaped door-plate connecting box equals the fan-shaped radian of fan-shaped doorframe connecting box, such structure can guarantee that fan-shaped door-plate connecting box is enclosed within the fan-shaped doorframe connecting box, in the door closing process, fan-shaped door-plate connecting box progressively is rotated in fan-shaped doorframe connecting box the inside, in the door opening procedure, fan-shaped door-plate connecting box progressively spins out from fan-shaped doorframe connecting box, such structure has guaranteed that whole revolving joint can block the crack between a door and its frame that forms between door-plate and the doorframe, thereby guaranteed that finger can not extend in the crack between a door and its frame, can prevent comprehensively that more finger from being crushed, simultaneously because the fan-shaped radian of fan-shaped door-plate connecting box and fan-shaped doorframe connecting box limits, can limit simultaneously a maximum angle of opening.
Further, limit the fan-shaped radian of described fan-shaped door-plate connecting box and the fan-shaped radian of fan-shaped doorframe connecting box and be 90 °.Such structure qualification, to consider, when only having the connecting box of two mutual fits, when namely only having fan-shaped door-plate connecting box and fan-shaped doorframe connecting box, can guarantee that the maximum opening of door is 90 °, play prevent from pointing crushed in, also the maximum opening of opposite house limits, prevent the door rear people from back side crushed.Because fan-shaped radian is 90 °, can guarantee that the connecting box of two fits overlaps fully, the conserve space position in addition.
Further, on the basis of technique scheme, the inner outer edge of box that limits described fan-shaped doorframe connecting box is provided with the fixture block to infolding, and the outer edge of described fan-shaped door-plate connecting box outside is provided with the block tongue of outside folding, and described fixture block and block tongue mate locking mutually.The inner outer edge of box that limits described fan-shaped doorframe connecting box is provided with the fixture block to infolding, the outer edge of described fan-shaped door-plate connecting box outside is provided with this structure of block tongue of outside folding, can guarantee that fan-shaped door-plate connecting box is when extracting out from fan-shaped doorframe connecting box, form the structure of mutual hook, make fan-shaped door-plate connecting box not exclusively break away from fan-shaped doorframe connecting box; Simultaneously, the setting of this structure also is conducive to install, and can directly fan-shaped door-plate connecting box be advanced fan-shaped doorframe connecting box, need to not get final product by other instrument, and is convenient and practical.
