A door hinge that can be parked continuously and has a power assist function

Abstract

The invention relates to door hinges, in particular to a door hinge with continuous stop and a power assist function. The door hinge mainly comprises a door frame upper half sheet, a pressing cover, mimus screws, a door lower half sheet, a door frame lower half sheet, a door upper half sheet, a shaft sleeve, two wave pressing plates, four springs, a wave pipe I, a pin, a long key, two torsion springs, and a wave pipe II. Key grooves are formed in axis holes of the wave pipe I and the wave pipe II. The wave pipe I and the wave pipe II are connected with the pin by the long key, and are arrangedon the limiting end faces in axis holes of the door lower half sheet in a sleeving mode. Protruding convex wavy strips are arranged on three quarters of the surfaces of the circumferences of the outer lateral faces of the wave pipe I and the wave pipe II. A protruding longitudinal concave wavy strip is arranged on the inner side of the wave pressing plate. The concave wavy strip is engaged with the convex wavy strips. One ends of the springs are fixed into limiting holes outside the wave pressing plate. A limiting pit is formed in the pressing cover. The other ends of the springs are matchedand connected with the limiting holes of the pressing cover. The four springs are assembled in the pressing cover is a limiting mode. The pressing cover is matched with a preformed groove of the doorlower half sheet.

Description

technical field [0001] The invention relates to a door hinge, in particular to a door hinge capable of continuous parking and with a power-assisted function, which can realize the continuous parking of the door at different angles and has the opening and closing of the power-assisted door. 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 at the required position, 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 However, on the one hand, the door stopper is only used for the fully open state of the door; The hole is fixed, which will destroy the integrity and affect the appearance. Moreover, if the wall an...

[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 at the required position, 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 However, on the one hand, the door stopper is only used for the fully open state of the door; The hole is fixed, which will destroy the integrity and affect the appearance. Moreover, if the wall and the floor are made of ceramic tiles, it is difficult to drill holes on it. At the same time, the integrity of the wall or the floor is destroyed. In addition, considering To save effort when opening and closing the door, the door hinge that can be parked continuously and has power-assisted function can solve the problem
