Ring-type stone secret door skeleton structure

Abstract

The invention discloses a buckle type stone blank door skeleton structure. The structure comprises a doorframe skeleton and a blank door skeleton. A first rotating shaft and a second rotating shaft are arranged on one side of the doorframe skeleton; a rotating shaft groove is arranged in the first rotating shaft along the axial direction of the first rotating shaft; the second rotating shaft is eccentrically mounted in the rotating shaft groove; a multi-link rod is arranged between the second rotating shaft and the inner wall of the rotating shaft groove; one end of the multi-link rod is fixedly connected to the outer wall of the second rotating shaft; and the other end of the multi-link rod is in rotatable connection with the inner wall of the rotating shaft groove. One side of the blank door skeleton is in rotatable connection with the second rotating shaft. Compared with the prior art, the opening angle of the stone blank door can be adaptively adjusted, so that an edge bumping problem which occurs at the stone arranged at the two ends of a conventional rotating shaft due to the opening angle is solved, and therefore workers can normally enter an access door for maintenance work.

Description

technical field [0001] The invention relates to a skeleton structure of a secret door, in particular to a skeleton structure of a ring-type stone secret door. Background technique [0002] In the stone wall decoration project, the purpose of the stone movable secret door and the maintenance hole is to clean, repair and maintain the equipment, pipes and pipelines on the surface of the decoration material in daily use, so as to ensure the normal operation of its supporting equipment. A set openable decorative surface activity unit. As the appearance of modern decorative structures is changing with each passing day, the use of stone will be emphasized in the decorative space, so there will be a large number of movable secret doors and holes of stone that need to be decorated, and at the same time, it is necessary to achieve the decorative effect without affecting its basic structure. However, most of the stone secret doors of various projects are made on-site, with simple tech...

AI Technical Summary

Problems solved by technology

For example: the hinge hinges and spring hinges of ordinary finished products are constrained by the product itself, and it is not easy to modify, change, and adjust its structural size. It can only be used on relatively ordinary decorative movable components, which has relatively large limitations. Due to the problem of "collision" of stone materials at both ends of the conventional rotating shaft, the opening angle is generally less than 90 degrees, which affects the normal use of entering the maintenance door for maintenance
