As improvement of the technical scheme, described transmission mechanism comprises the motor that is arranged in the rot casing, the output shaft of described motor is provided with sprocket wheel, and described turner casing top is provided with the drive sprocket that cooperates with described chain gear transmission, and described drive sprocket and described rotation axis are rotatably assorted.
As further improvement in the technical proposal, the outside of the rotation axis of described and drive sprocket loose fit is provided with the adjustment screw that can regulate contact friction force between rotation axis and the drive sprocket, is provided with the volute pad between described adjustment screw and the drive sprocket.
As further improvement in the technical proposal, be fixedly connected with the limit switch collision block on the rotation axis of described drop front, also be provided with the limit switch that can touch when the limit switch collision block rotates in the described turner casing.
As further improvement in the technical proposal, also be provided with different in nature pad between described drive sprocket and the volute pad.
As further improvement in the technical proposal, be provided with the trip bolt of fixedlying connected in the through hole of described adjustment screw middle part with rotation axis.
The beneficial effects of the utility model are: owing to be loose fit between the drop front rotation axis of display screen turner of the present utility model and the transmission mechanism; when display clips to staff in switching process; staff gives the torque of drop front for the resistance of drop front greater than transmission mechanism; at this moment; skid between rotation axis and the transmission mechanism, stoped transmission mechanism to continue to drive drop front and rotated, thereby prevented that staff from being crushed; eliminate potential safety hazard, and protected the safety of machine.

Embodiment
Referring to figs. 1 through Fig. 6, a kind of display screen turner with anti-tong function, comprise turner casing 1, the transmission mechanism that is provided with in the described turner casing 1, described turner casing 1 top is provided with the drop front with rotation axis 21 2 that is driven by described transmission mechanism, described drop front 2 one sides are equipped with can be with the display 3 of drop front 2 rotations, and described rotation axis 21 is that pine is rotatably assorted with described transmission mechanism.Owing to be loose fit between the drop front rotation axis of display screen turner of the present utility model and the transmission mechanism; when display clips to staff in switching process; staff gives the torque of drop front for the resistance of drop front greater than transmission mechanism; at this moment; skid between rotation axis and the transmission mechanism, stoped transmission mechanism to continue to drive drop front and rotated, thereby prevented that staff from being crushed; eliminate potential safety hazard, and protected the safety of machine.
As preferably, transmission mechanism in the present embodiment comprises the motor 4 that is arranged in the rot casing 1, the output shaft of described motor 4 is provided with sprocket wheel 41, described turner casing 1 top is provided with the drive sprocket 42 that cooperates with described sprocket wheel 41 transmissions, described drive sprocket 42 is rotatably assorted with described rotation axis 21, when motor 4 operations, pass through chain gear transmission, the torque meeting of drive sprocket 42 outputs on the rotation axis 21, rotate thereby drive drop front 2, realize being hidden in display screen in the casing or turn to outside for people to use.Certainly, also can adopt many kinds of drive such as belt pulley transmission, gear drive, those skilled in the art can make all equivalent transformations to the kind of drive, give unnecessary details no longer one by one at this.
In conjunction with Fig. 6, the outside of the rotation axis 21 of described and drive sprocket 42 loose fits is provided with the adjustment screw 23 that can regulate contact friction force between rotation axis 21 and the drive sprocket 42, is provided with volute pad 24 between described adjustment screw 23 and the drive sprocket 42.Like this, frictional force deficiency between drive sprocket 42 and rotation axis 21 when drop front 2 can't rotate, can make volute pad 24 increase distortion by tightening this screw, increase the thrust between drive sprocket 42 and the rotation axis 21, make drive sprocket 42 can drive drop front 2 and rotate.Otherwise, if do not have the effect of anti-tong, this screw can be changeed pine, turn the thrust between drive sprocket 42 and the rotation axis 21 down.
In order to realize automatic control, be fixedly connected with limit switch collision block 5 on the rotation axis 21 of described drop front 2, also be provided with the limit switch 6,7 that can touch when limit switch collision block 5 rotates in the described turner casing 1.Limit switch collision block 5 is along with drop front 1 rotation axis 21 rotates synchronously, and when limit switch collision block 5 forwarded the position of setting to, collision block triggered limit switch 6 or 7, and control circuit makes motor 4 outages, reaches the purpose of automatic control.
In order to prevent that loosening phenomenon from appearring in adjustment screw 23, also is provided with different in nature pad 25 between described drive sprocket 42 and the volute pad 24.In addition, be provided with the trip bolt 27 of fixedlying connected with rotation axis 21 in the described adjustment screw 23 middle part through holes 26, like this, adjustment screw 23 will be prevented that it from running, and causes machine failure by firm being fixed on the rotation axis 21.
In addition, in the present embodiment, described motor 4 and chain wheel driving mechanism are in a wherein side of whole turner casing 1, and 5 another examples at casing 1 of limit switch 6,7 and limit switch collision block make product with compact structure, deft design, have antitheftly, the dustproof desktop that keeps is smooth, beautifies functions such as desktop.Certainly, these structures all can also be arranged in a side of the utility model rot casing 1, or all there is layout both sides, those skilled in the art can be according to the actual conditions setting.
Certainly, the invention is not limited to above-mentioned execution mode, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
