An object of the utility model is to provide a reasonable in design, convenient to use, have stop gear's auditorium chair tablet support plate axle revolution mechanic to prior art's defect and not enough.
In order to achieve the above object, the utility model adopts the following technical scheme: it comprises a rotary arm, a writing board supporting plate, a limiting screw and a spring; one end of the spiral arm is provided with a rotating shaft through hole, the other end of the spiral arm is provided with a supporting plate mounting hole, and a C-shaped limiting notch is arranged on the supporting plate mounting hole; the writing board supporting plate is of a plate-shaped structure with a rotating shaft, writing board fixing holes are formed in the corners of the writing board supporting plate, and limiting screw holes are formed in the rotating shaft; a spring is arranged in the supporting plate mounting hole on the spiral arm; the rotating shaft on the writing board supporting plate is arranged in the supporting plate mounting hole and is connected with the spring in a pressing manner; the limiting screw is in threaded connection with the limiting screw hole, so that the rotating shaft of the writing board supporting plate is limited to rotate in the limiting notch.
Furthermore, the rotating shaft through hole of the rotating arm is axially vertical to the supporting plate mounting hole, and the whole rotating shaft through hole is T-shaped.
Furthermore, the maximum rotation angle of the rotation shaft on the writing board supporting plate in the limiting notch is 90 degrees.
After the structure is adopted, the utility model discloses beneficial effect does: the utility model discloses auditorium chair tablet support plate axle rotating-structure has stop gear, makes the rotatory angle restriction of tablet support plate within 90 degrees, and the difficult condition of walking the position that takes place to overturn, reasonable in design, simple and practical, with low costs, easy popularization, through spacing screw installation can, the installation is simple and easy swift.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
FIG. 1 is an exploded perspective view of an embodiment of the present invention;
description of reference numerals:
1. a swing arm; 2. a tablet support plate; 3. a limiting screw; 4. a spring; 101. a through hole of the rotating shaft; 102. a pallet mounting hole; 103. a limiting notch; 201. a rotating shaft; 202. a limiting screw hole; 203. a writing board fixing hole.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1, the technical solution adopted by the present embodiment is: it comprises a rotary arm 1, a writing board supporting plate 2, a limit screw 3 and a spring 4; one end of the spiral arm 1 is provided with a rotating shaft through hole 101, the other end of the spiral arm is provided with a supporting plate mounting hole 102, and a C-shaped limiting notch 103 is arranged on the supporting plate mounting hole 102; the writing board supporting plate 2 is of a plate-shaped structure with a rotating shaft 201, a writing board fixing hole 203 is formed in the corner, and a limiting screw hole 202 is formed in the rotating shaft; a spring 4 is arranged in the supporting plate mounting hole 102 on the spiral arm 1; a rotating shaft 201 on the writing board supporting plate 2 is arranged in the supporting plate mounting hole 102 and is connected with a spring 4 in a pressing mode; the limiting screw 3 is in threaded connection with the limiting screw hole 202, so that the rotating shaft 201 of the writing board supporting plate 2 is limited to rotate in the limiting notch 103.
