The crank arm 6 rotates to push a first four-bar linkage mechanism of a parallelogram formed by the door body connecting rod 3, the crank arm 6, the door body 1 and the support to operate, so that the door body 1 can move upwards and rightwards, and the door body 1 is always parallel to the hole wall in the moving process, as shown in fig. 6. Until the stroke of the driver 9 is extended to the maximum, the crank arm 6 rotates to the limit position, the door body 1 is completely opened, and the state shown in fig. 5 is achieved. When the door body 1 is closed from an opening state, the equipment starts to work from a static state, the driver 9 starts to retract, and the rocker 12 is driven to rotate anticlockwise; under the action of a second four-bar linkage mechanism consisting of the crank arm 6, the driving connecting rod 8, the rocker 12 and the support, the crank arm 6 is driven to rotate anticlockwise, and the rotating angle of the driving crank arm 6 is enlarged. The crank arm 6 rotates to push the first four-bar linkage mechanism of the quadrangle formed by the door body connecting rod 3, the crank arm 6, the door body 1 and the support to operate, the door body 1 is enabled to move horizontally downwards leftwards, the door body 1 is parallel to the hole wall all the time in the moving process, and the state of the graph 3 is achieved until the door body 1 is completely closed.
The present invention is not limited to the above-described embodiments, and it will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and such modifications and improvements are also considered to be within the scope of the present invention. Those not described in detail in this specification are within the skill of the art.
