an automatic door contact type anti-clamping mechanism comprises a door frame and a movable door body, wherein a door hole is formed in the door frame, the door body can be clamped into the door hole in a movable manner, a fixed supporting frame is arranged on one side of the door hole in the door frame, a downward through chute is formed in the supporting frame, an opening is formed in one side of the chute and is positioned at a corner opposite to the side edge of the door hole opposite to the moving direction of the door body, a telescopic block is arranged at one end, close to the opening, in the chute, the two sides of the chute limit the telescopic block to guide the movement of the telescopic block, a micro switch is arranged at the bottom of the chute, a connecting plate is fixedly connected to the inner wall of the chute and is positioned between the micro switch and the telescopic block, an elastic element is arranged between the connecting plate and the inner side end face of the telescopic, one end of the elastic element is fixedly connected with the end face of the telescopic block, a pressing rod is fixedly connected to the end face of the inner side of the telescopic block, the pressing rod is inserted into an inner ring of the elastic element in a penetrating mode, a through hole is formed in the middle of the connecting plate, the other end of the pressing rod penetrates through the through hole and abuts against the surface of a driving button of the micro switch, and the elastic element enables the outer side of the telescopic block to be flush with the door opening.
Further, the elastic element is a compression spring.
Furthermore, a guide rail is arranged on one side of the door frame and distributed on two sides of the door opening, and the door body is installed on the guide rail and moves along the guide rail.
In another scheme, the middle part of the door body is hinged on a door opening, and the door body is clamped in the door frame through rotation.
The utility model provides a pair of automatic door contact prevents pressing from both sides mechanism has following beneficial effect: the utility model provides a contact type anti-pinch mechanism, after clamping a person or an object, the telescopic block is extruded, the telescopic block is contracted and slides towards the inside of the chute, the pressing rod on the telescopic block extrudes the driving button of the micro switch, the driving button acts to touch the micro switch, thereby immediately sending a prompt signal to a control system to enable the control system to timely stop the operation of a door body driving power device or retreat the operation instruction, thereby preventing the human body or the object from being clamped; when the telescopic block is extruded, the compression spring contracts, the telescopic block contracts and moves towards the inside of the sliding groove, a certain amount of clamped human bodies or objects are avoided, and when the clamped human bodies or the clamped objects are removed, the elastic element ejects and resets the telescopic block.
Description of the drawings:
the following detailed description of embodiments of the present invention is provided with reference to the accompanying drawings:
fig. 1 is a schematic structural view of an automatic door contact type anti-pinch mechanism provided by the present invention;
