Detailed Description
Referring to the drawings, the utility model provides a point reading machine support device, including support 1 and the hinge that support and point reading machine body 100 connect, the hinge includes circular arc guide rail 21 and circular arc slider 31 connected with circular arc guide rail in a sliding manner; the arc-shaped sliding block 31 is formed on a main body 3 and is connected to the inner side of the bracket 1 through the main body 3; the arc-shaped guide rail 21 is arranged on the point reading machine body 100; the central angle of the arc-shaped guide rail is less than 180 degrees, and the circle center A is positioned above the connecting line of the two ends of the arc-shaped guide rail 21; the hinge is also provided with a control mechanism of the circular arc-shaped sliding block so as to control the circular arc-shaped sliding block 31 to slide to different stop angles and be kept at the stop angles.
The different stay angles in this embodiment include an angle when the corresponding stand 1 is in a closed state, an angle when the corresponding stand 1 is opened to a first support angle, and an angle when the corresponding stand 1 is opened to a second support angle, wherein the second support angle is greater than the first support angle.
The control mechanism is provided with a spring 4 and comprises a swing cam 5, a plurality of stay angle locking matches are arranged between the swing cam 5 and the arc-shaped sliding block 31, and the locking matches are kept through the spring force of the spring 4. The locking engagement portion on the side of the circular arc slider 31 may be provided on the body 3 of the circular arc slider 31, and may be a hook 32. The swing cam can be provided with gears respectively corresponding to the different stay angles, namely a gear 51 corresponding to the bracket 1 in a closed state, a gear 52 corresponding to the bracket 1 opened to a first support angle, and a gear 53 corresponding to the bracket 1 opened to a second support angle. When the hook 32 is in locking fit with any one gear, the locking fit is kept through the spring force of the spring 4, when the bracket 1 needs to be opened or closed or the supporting angle of the bracket 1 needs to be adjusted, the bracket 1 is pulled by hand, after the spring force of the spring 4 is overcome, the swinging cam 5 swings backwards to release the locking fit, and after the bracket 1 rotates to the next angle, the bracket enters the locking fit at another stopping angle.
