Description

Door hinge structure

This creation is about a hinge, especially a door hinge structure that pivots smoothly and evenly.

Generally, glass door panels are usually hinged on a door frame using a door hinge. The door hinge has a fixed seat that can be fixed on the door frame, and a pivot seat is set on one side of the fixed seat. The pivot seat A pivot assembly is used to pivotally connect a set of clamping components composed of two clamping plates, and the two clamping plates cooperate with screws to clamp and clamp a glass door panel. By setting the door hinge, the glass door panel can be rotated to open Or close.

Such as the announcement of the new patent case No. M570342 "Door hinge structure with variable angle", it is a conventional door hinge, which includes: a fixed seat, a clamping seat, a pivoting member and a pivot, the clamping The seat is provided with two pivotal parts opposite to each other, a pivot slot is provided between the two pivot parts, the pivot member is disposed in the pivot slot of the clamping seat, the pivot member is provided with a pivot end and a The pivoting end is opposite to the connecting end, the pivoting end is provided with a shaft hole, the connecting end is connected and fixed with the fixing seat, and the pivoting member is provided with a containing hole and the receiving hole in the direction of the pivoting end from the connecting end The shaft hole communicates with each other, an elastic contact unit is installed in the accommodating hole, the pivot shaft is rotatably penetrated through the pivot hole of the pivoting member, and both ends of the pivot shaft are combined with the two pivotal joints of the clamping base Fixed, one side of the middle section of the pivot is provided with a flat-cut positioning portion for the elastic abutment unit to abut against the positioning.

However, although the hinge of the conventional door can be closed, the flat-shaped positioning portion of the pivot shaft is resiliently impacted by the resilient unit to form a positioning effect, but the glass door assembled with the hinge of the conventional door rotates When it is turned on and off, there will be a problem of speed going up and down, causing the problem of unsmooth rotation, and it is indeed necessary to improve it.

In view of the above-mentioned shortcomings of the hinge of the conventional door, the creator created the creation after discussing and trial-making samples and revising and improving it for many times.
