Description
Technical Field
The utility model relates to a hinge field, especially a powerful anti-falling hinge.
Background
A hinge is a device that connects a door to a doorframe. At present, the hinge is mainly of a single fixing seat and a single rocker structure, the fixing seat of the hinge is fixed on a door due to the stress direction, the rocker is fixed on a door frame, and the rocker is connected with the fixing seat through a pin shaft, so that the door can be smoothly and rotatably opened or closed. The door is heavy and the weight is completely exerted on the hinge, and under the condition that the hinge bears the weight of the door for years, the pin shafts of the two rocker arm hinges bend, so that the door inclines and falls down, and the door frame is rubbed or collided. And the fixed orifices on the hinge fixing seat are mostly arranged in a linear type or a broken line type, and the fixing seat is fixed on the door frame by passing screws through the fixed orifices, and the screws can gradually incline under the action of the gravity of the door, so that the hinge is loosened, and the door inclines and falls.
For example, application number is CN 201210490465.0's security protection door hinge, when going up the hinge and drive the door and rotate, the door can exert a decurrent gravity to the hinge, still can exert a horizontal force to the pivot, the pivot is under the long-term effect of horizontal force, the pivot can be crooked gradually at the position of upper and lower hinge junction, influence the cooperation of door and doorframe, and this security protection door hinge's last hinge and lower hinge direct contact, and go up the hinge and be provided with the slope between the hinge down, the hinge can go up hinge and lower hinge direct friction when rotating, it is serious to go up the hinge and wear and tear down between the hinge, and can send the noise.
For the hinge with double fixing seats and single rocker structure disclosed, for example, a door hinge for an ice chest with application number 201621229433.5, the fixing holes of the two fixing seats on the hinge are both set to be two, and the fixing holes are far away from the pin shaft, the door can apply a horizontal torsion force to the fixing pins under the action of gravity, the fixing pins transmit the horizontal torsion force to the fixing screws, the fixing screws are simultaneously subjected to the horizontal torsion force under the downward gravity of the door, and the two fixing screws are positioned in the relative up-and-down directions, so that the bearing capacity of the horizontal torsion force is poor, and the fixing seats are easy to incline. The rocker arm of the door hinge for the refrigerator is matched with the upper fixing seat and the lower fixing seat through the limiting rod and the limiting rod hole respectively, so that the rocker arm and the fixing seats cannot swing to the same plane, namely when the rocker arm and the fixing seats swing to the minimum angle, the thickness of the hinge is at least the sum of the thicknesses of the rocker arm and the fixing seats, and the closing thickness of the hinge is large. And present door hinge generally installs on the side of the bobbin board of door frame and door plant, and wherein the bobbin board indicates the door frame side board of perpendicular to wall, and hinge thickness is big more then the mounting groove that needs processing is big more on bobbin board and the door plant, and the thickness requirement to the door frame is very high. This a fixing base and rocking arm direct contact for door hinge of refrigerator-freezer, the pinhole contact point of opening at the door and closing in-process rocking arm and fixing base can take place wearing and tearing, because wearing and tearing take place on one side near the door, so the wearing and tearing on the hinge are unbalanced, under the wearing and tearing of the year moon year round, the pinhole department of hinge can grind out an inclined plane, the hinge can be automatic to the lowest department in slope under the gravity of door, be unfavorable for the switch of door, and it is troublesome to change the hinge process, it is big to the damage of door and door frame, it is not applicable to in the daily life to change the hinge.
For another example, the application number of 201820114818.X is a novel door hinge structure of an anti-falling door, a fixed seat of the door hinge structure of the anti-falling door is of an L-shaped structure, and is not suitable for being installed on the side faces of a cylindrical plate and a door plate of a door frame, and threads, straight key grooves and spiral grooves are arranged inside the door hinge structure of the anti-falling door, so that the anti-falling door has multiple processing procedures and complex installation procedures. There are problems of high manufacturing cost, difficulty in installation and low installation efficiency.
