Description
Technical field
The utility model belongs to the security door bulking block, especially a kind of 180 degree blind hinges.
Background technology
Security door on the market, steel door etc. are general to adopt the punching press of C type can dim hinge, opens the door leaf angle generally about 90, in public places or install and use its on the narrow corridor and can bring inconvenience to the user.Because security door, steel door, be installed in wall face and outwards opening usually, existing dark hinge can not be opened to 180 degree, causes door leaf can not paste metope and opens and block passageway or corridor and influence neighbours and pass in and out, and has hindered user's life and work.
The utility model content
The technical problems to be solved in the utility model provides that a kind of simple and beautiful structure is generous, volume is very little does not take up space, assembles the solid 180 firm degree blind hinges of easy pick-proof easy to use, safe.
Adopt following technical scheme for solving the problems of the technologies described above the utility model: 180 degree blind hinges mainly are made of L type blind hinge plate, middle-end flap, three end flaps and the protruding circle fixed bar of camber band; The short slab side of L type blind hinge plate by an end ship and resell on another market axle and doorframe fixedly U type seat be connected, its long slab side is passed through the adjusting bolt and is connected with the long slab side of middle-end flap; The short slab side of middle-end flap and three end flaps are connected by the three ends axle axle of shipping and reselling on another market; The protruding circle fixed bar of camber band passes the hole on the short slab side that is located at the middle-end flap and drives jump ring, and an end is fixed on the three end flaps, and the other end is the camber alignment pin.
180 degree blind hinges of the present utility model adopt three grades of flaps, make door leaf revolve and turn 90 degrees around the end axle of shipping and reselling on another market, and under three end flaps and the effect of the protruding circle fixed bar of camber band, can also revolve again and turn 90 degrees around the three ends axle of shipping and reselling on another market, thereby realize the random folding of door leaf 0～180 degree, press close to wall face after opening door leaf, elimination is blocked the passageway, makes narrow space no longer crowded.The utility model design science is reasonable, and volume simple in structure is little, can be installed in easily in the hidden doorframe, and hinge does not expose when guaranteeing that door leaf cuts out, and safety pick-proof is applicable to various security doors, steel door or other indoor nonstandard engineering doors more.
