A door hinge that can be parked at any angle by using the thread self-locking function

Abstract

The invention relates to door hinges, in particular to a door hinge capable of achieving parking at random angle through the thread self-locking function. The door hinge mainly comprises a sliding block, an inner hexagon nut I, a connecting rod, a fixed hinge, a guide rail, a center shaft, a blocking piece, a locking fixed screw cap, a left-hand rotating moving screw cap, a pressure spring, aright-hand rotating moving screw cap, a rotating hinge, a shell, an inner hexagon bolt, an inner hexagon nut II, a fixed plate and a hinge fixing shell; a left-hand thread and a right-hand thread are arranged at the two ends of the center shaft correspondingly, the lengths and the screw pitches of the left-hand thread and the right-hand thread are equal, the pressure spring is arranged on the middle segment of the periphery of the center shaft in a sleeving manner, the left-hand moving screw cap and the right-hand moving screw cap are screwed in from the two ends of the center shaft and are in abutjoint with the two ends of the pressure spring tightly, and the pressure spring is pre-tightened; the left-hand moving screw cap and the right-hand moving screw cap are connected with sliding blocksthrough the inner hexagon nuts and the connecting rods, the two sliding blocks are matched with the guide rail, and under the pressure effect of the pressure spring, threads in the left-hand moving screw cap and the right-hand moving screw cap generate enough self locking.

Description

technical field [0001] The invention relates to a door hinge, in particular to a door hinge which can prevent the automatic closing of the door and realize the door parking at any angle by using the self-locking function of the thread to realize the parking at any angle. Background technique [0002] In our life, doors are everywhere, but in the process of using the door, sometimes it needs to be slightly opened, sometimes it needs to be half-opened, and sometimes it needs to be fully opened. As for how to position the door, after the door is opened, if it cannot be positioned properly, the door will be forced to close due to wind or collision, and sometimes the door will be damaged. The current solution on the market is to choose a door stopper, but On the one hand, the door stopper is only used for the fully open state of the door. On the other hand, during the installation process of the door stopper, it is necessary to punch holes on the door, or on the floor, or on the ...

[0002] In our life, doors are everywhere, but in the process of using the door, sometimes it needs to be slightly opened, sometimes it needs to be half-opened, and sometimes it needs to be fully opened. As for how to position the door, after the door is opened, if it cannot be positioned properly, the door will be forced to close due to wind or collision, and sometimes the door will be damaged. The current solution on the market is to choose a door stopper, but On the one hand, the door stopper is only used for the fully open state of the door. On the other hand, during the installation process of the door stopper, it is necessary to punch holes on the door, or on the floor, or on the wall. , this will destroy the integrity and affect the appearance. Moreover, if the wall and the ground are made of ceramic tiles, it will be difficult to punch holes on it. At the same time, the integrity of the wall or the ground will be destroyed. The lock function realizes the door hinge that can be parked at any angle can solve the problem
