Detailed Description

As shown in fig. 2 and 3, the present invention relates to a safety door assembly structure for washing machine, which is characterized in that it comprises a bracket 2; on the bracket 2, a frame 1-2 is arranged from top to bottom to place a board 2-2 and an press-in structure, in the technical scheme of the utility model, the cover body 1-1 of the safety door cover is pressed into the frame 1-2 through the press-in structure.

The pressing structure comprises a cylinder 3, a sucking disc 4-4 and a pressing block 4-6 which are fixed on the bracket 2; the cylinder 3 is fixed on the bracket 2 through a cylinder mounting plate 2-1. A piston rod 3-1 of the cylinder 3 is vertically and downwards arranged above the placing plate 2-2 of the frame 1-2, and a pressing block 4-6 is fixed at the bottom of the piston rod 3-1 of the cylinder 3; the bottom end surface of the pressing block 4-6 is a plane with the area smaller than that of the flat bottom groove 1-4 on the cover body 1-1; the top end face of the frame placing plate 2-2 is provided with a frame accommodating cavity 2-3 positioned under the piston rod 3-1, and the shape of the cavity of the frame accommodating cavity 2-3 is matched with the shape of the frame 1-2 of the safety door cover. When the safety door is specifically implemented, the frame accommodating cavities 2-3 are arranged through the placing plates 2-4, and the frame accommodating cavities 2-3 with different shapes are arranged on the placing plates 2-4, so that the technical scheme of the utility model is suitable for assembling safety door covers with different models.

The sucking disc 4-4 is installed in the piston rod 3-1 bottom of cylinder 3 through buffer structure, and buffer structure includes: a buffer spring 4-3 and a guide post 4-2 connected with the piston rod 3-1, wherein one end of the buffer spring 4-3 is fixed on the guide post 4-2, and the other end is vertically and downwards fixedly connected with a sucker 4-4.

The length of the guide post 4-2 is less than the height of the pressing block 4-6; the lowest end of the buffer spring arranged on the guide post 4-2 in a sagging state due to gravity is lower than the bottom end surface of the pressing block 4-6; after the sucker 4-4 is arranged at the bottom end of the buffer spring 4-3, the sucker is positioned below the pressing block 4-6, and therefore when the piston rod downwards grabs the cover body 1-1, the sucker 4-4 is firstly contacted with the cover body 1-1.

During specific implementation, the frame accommodating cavity 2-3 is located under the piston rod 3-1, and the vertical projection of the piston rod 3-1 is located at the intersection point of the central points of the length and the width of the frame accommodating cavity 2-3, so that the cover body 1-1 can be completely placed into the clamping groove 1-3 of the frame 1-2 when the piston rod 3-1 descends. As shown in figure 5, the bottom end surface of the pressing block 4-6 is symmetrically arranged along the length direction and the width direction of the central point of the flat-bottom groove 1-4, so that when the pressing block 4-6 applies downward pressure, the bottom end surface of the pressing block 4-6 applies force to the flat-bottom groove 1-4 uniformly, and the structure of the cover body 1-1 cannot be damaged.

The bottom of the piston rod 3-1 is provided with a connecting plate 4-1, the top end face of the connecting plate 4-1 is fixedly connected with the bottom end of the piston rod 3-1, a pressing block 4-6 is arranged on the bottom end face of the connecting plate 4-1 and is positioned right below the piston rod 3-1, and guide pillars 4-2 are uniformly arranged on the periphery of the pressing block 4-6; the guide post 4-2 is detachably and fixedly arranged on the connecting plate 4-1 through a screw rod 4-5 and a nut 4-8.

As shown in FIG. 4, in this embodiment, the guide post 4-2 is a cylindrical structure, and the inner cavity is provided with internal threads, and is fixed on the connecting plate 4-1 by a screw 4-5 based on thread engagement and is fixed by a nut 4-7. The bottom end face of the pressing block 4-6 is rectangular, and four guide pillars are uniformly arranged at four corners, so that the compressed buffer spring 4-3 can uniformly buffer when the pressing block 4-6 applies force downwards. Meanwhile, the number of the guide posts 4-2 and the suckers 4-4 can be adjusted according to the thickness and the shape of the safety door cover, so that the technical scheme of the patent is suitable for assembling various safety door covers of different models.

When the safety door cover assembly structure adopting the technical scheme of the utility model is used, the frame 1-2 is placed in the frame accommodating cavity 2-3 by the frame feeding device (not marked in the figure), the cover body to be assembled 1-1 is placed right above the frame accommodating cavity 2-3 by the cover body feeding device (not marked in the figure), the air cylinder 3 is started, the piston rod 3-1 moves downwards, and the sucking disc 4-4 and the pressing block 4-6 are driven to move downwards; when the suction cup 4-4 contacts the flat bottom groove 1-4 and the buffer spring 4-4 is pressed tightly, the cylinder 3 is stopped, and the suction cup 4-4 is started; the cover body 1-1 is sucked by the sucking disc 4-4, and the cover body feeding device is withdrawn; starting the air cylinder 3, enabling the piston rod 3-1 to continuously move downwards to drive the cover body 1-1 to move downwards, compressing the buffer spring 4-4 above the sucker 4-4 after the cover body 1-1 is pressed on the clamping groove 1-3, enabling the piston rod 3-1 to continuously move downwards until the pressing block 4-6 is pressed in the flat bottom groove 1-4 of the cover body, pressing the cover body 1-1 into the clamping groove 1-3, and completing the assembly work of the door cover; the cylinder 3 is stopped and then started reversely; the piston 3-1 drives the assembled safety door cover to move upwards to a preset discharging position, and the air cylinder 3 stops; after a safety door cover discharging device (not marked in the figure) receives the safety door cover, the suction disc 4-4 stops working, and the safety door cover is released; and starting the air cylinder 3, continuously moving the piston rod 3-1 upwards, driving the sucking disc 4-4 and the pressing block 4-6 to default positions, and stopping the air cylinder 3 to finish the assembly and discharge processes of arranging the door cover.
