Novel integral-bearing adjustable connecting part

Abstract

Disclosed is a novel integral-bearing adjustable connecting part. The novel integral-bearing adjustable connecting part is formed by assembling two hinge leaves, end cover screws, dustproof end covers, adjusting screws, bearing covers, an integral bearing, wear-resisting steel balls, a fixed core shaft and hinge leaf pipe portions. In the mounting process, firstly, the fixed core shaft is fixed to the middle of the pipe portion of the one-tooth hinge leaf, and therefore the integral bearing is in interference fit with the one-tooth hinge leaf; then, the two hinge leaves are assembled, and the integral bearing is put into the common pipe portion of the two hinge leaves (attention direction), so that the integral bearing is in loose running fit with the two-tooth hinge leaf; the wear-resisting steel balls are added on the integral core shaft, then, the bearing covers are put on the wear-resisting steel balls, the adjusting screws are screwed on, and the connecting part is free of abnormal sounds, vibration and gaps; and the dustproof end covers are put at the two ends of the pipe portions, and finally, the dustproof end covers are adjusted and fixed through the end cover screws.

Description

technical field [0001] The invention relates to a connecting piece between a door, a window and a frame, more specifically, a new integral bearing adjustable hinge that can adjust the gap and tightness of the hinge by adjusting screws to achieve no abnormal sound, no vibration, and no gap. At the same time, the gap between the door and the frame can be adjusted. The new integral bearing adjustable connector is a combination of the mandrel and the bearing, reducing parts, saving costs, increasing strength, and increasing bearing capacity. Background technique [0002] At present, the hinges on the market are mostly assembled by two-tooth leaf, three-tooth leaf, mandrel, and end cover. After assembling the two-tooth leaf and the three-tooth leaf, string the mandrel into the common pipe. , the end caps are embedded in both sides of the tube through interference fit. This kind of hinge has poor lubricity when used in doors and windows, and it is difficult to open and close the ...

AI Technical Summary

Problems solved by technology

This kind of hinge has poor lubricity when used in doors and windows, and it is difficult to open and close the doors and windows, and sometimes there will be abnormal noises, and lubricants need to be added. After a period of use, the hinges are severely worn and need to be replaced.

Moreover, the flexibility is poor, and the function of adjusting the position and gap cannot be achieved, which brings inconvenience to the actual installation
