Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The invention provides a jacquard demonstrating device aiming at the problems that the working principle and the interactivity of the existing jacquard can not be clearly demonstrated.
As shown in fig. 1-3, an embodiment of the invention provides a jacquard demonstrating device, which comprises a base 1, a transparent shell 2 arranged on the base 1 and a jacquard structure arranged on the base 1 and positioned inside the transparent shell 2;
the jacquard structure comprises a hand wheel 3 arranged outside a transparent shell 2, a driven gear 5 arranged inside the transparent shell 2 and connected with the hand wheel 3, a driven gear 5 meshed with the driving gear 4, a first connecting rod 6 and a second connecting rod 7 arranged on the driven gear 5, a lifting rod 8 arranged on the transparent shell 2 and connected with the first connecting rod 6, a decoding block 9 connected with the second connecting rod 7, a hole plate belt 10 arranged on the decoding block 9, a push rod 11 arranged inside the transparent shell 2 and positioned on the same horizontal plane with the hole plate belt 10, a hook 12 hung on the lifting rod 8 and connected with the push rod 11 at the bottom end, and a hole plate 13 arranged on the push rod 11 and far away from one end of the hole plate belt 10.
The principle of the jacquard demonstrating device is that the core component of the jacquard is enlarged and improved, and a transmission mechanism consisting of the driving gear 4, the driven gear 5, the connecting rod I6 and the connecting rod II 7 is used. The core component of the jacquard demonstration device and the transparent shell 2 are made of transparent acrylic materials, and a spectator can drive the whole device to move by rotating the external hand wheel 3 and observe from the outside.
In the demonstration process of the jacquard demonstrating device, a viewer rotates the hand wheel 3, the hand wheel 3 drives the driving gear 4 to rotate, the driving gear 4 drives the driven gear 5 to rotate, the driven gear 5 rotates to drive the first connecting rod 6 and the second connecting rod 7 to swing, the first connecting rod 6 drives the lifting rod 8 to vertically move back and forth, the second connecting rod 7 drives the decoding block 9 to horizontally move back and forth, and the lifting rod 8 and the decoding block 9 alternately move. The decoding block 9 drives the orifice plate belt 10 to rotate, the hand wheel 3 rotates one turn, the decoding block 9 rotates 90 degrees, and the orifice plate belt 10 moves by one unit. The horizontal back and forth movement of the decoding block 9 can push the push rod 11 to move horizontally.
The transparent casing 2 is symmetrically provided with a rectangular through hole 14 on the front and rear sides, two ends of the decoding block 9 are respectively located in the through hole 14, and the decoding block 9 can move horizontally along the through hole 14.
