Tripping-prevention positioning structure for door-return buffering device

Abstract

The invention discloses a tripping-prevention positioning structure for a door-return buffering device. The tripping-prevention positioning structure comprises a tripping-prevention shifting component which comprises a positioning piece, a shifting column and a fixing piece, the fixing piece is fixedly connected with the positioning piece, an internal threaded hole is arranged in the fixing piece, a first thread is arranged on the outer circumferential surface of the column body of the shifting column, the upper portion of the shifting column is connected in the inner threaded hole of the fixing piece through the thread, the door-return buffering device comprises a return buffering mechanism which is provided with a control piece, a shifted portion of the control piece is provided with a second thread, and the shifting column is detachably abutted against the shifted portion of the control piece by matching of the first thread and the second thread. By the arrangement, tripping of a door can be effectively prevented, the shifting column can be adjusted in height, and the entire door-return buffering device is applicable to upper door frames and doors different in height.

Description

technical field [0001] The invention belongs to the technical field of door return buffering, in particular to an anti-jump positioning structure for a door return buffer device. Background technique [0002] Such as figure 1 As shown, the current door body return buffer device generally includes a toggle member 15 fixed on the upper door frame 20 and a return buffer device body 10 arranged on the door body 21 . The toggle member 15 is provided with a toggle portion 151 . The return buffer device body 10 usually has a groove 11, and a return buffer mechanism 12 is arranged inside the return buffer device body 10, and the return buffer mechanism 12 includes at least one buffer rod 13 and a power connection with the buffer rod 13. The control member 14 is provided with a dialed portion 141, and the dialing portion 151 of the dialing member 15 and the dialed portion 141 of the control member 14 are detachably locked against each other. When opening and closing the door, the...

AI Technical Summary

Problems solved by technology

[0003] The current door return buffer device, when the user closes the door, the reaction force generated when the control part and the toggle part touch and jam each other easily makes the door jump, resulting in noise and unsmooth opening and closing actions, which in turn causes Product usability and reliability are poor

In addition, the height of the toggle piece is fixed, so that the general door body return buffer device cannot be applied to upper door frames and door bodies with different height differences, resulting in very limited practicability and applicability
