Control structure and ornament
The invention relates to a control structure and an ornament, the control structure comprises an air bag and an actuating portion which are communicated, the actuating portion comprises a fixed portion and a moving portion which are connected at an included angle, the fixed portion is close to the air bag relative to the moving portion, at least two moving portions are provided, a volume of the air bag is capable of being repeatedly increased and decreased, and when the volume of the air bag is decreased, air in the air bag is capable of entering the actuating portion, so that the moving portion is moved and the included angle between the fixed portion and the moving portion is increased, thus switching a folded state of the actuating portion to an unfolded state.
1. A control structure, comprising an air bag and an actuating portion which are communicated, wherein the actuating portion comprises a fixed portion and moving portions, the fixed portion and each moving portion are connected at an included angle, at least two moving portions are provided; wherein, when the air bag is squeezed, a volume of the air bag is decreased, and air in the air bag enters the actuating portion, so that the moving portion is moved and the included angle between the fixed portion and the moving portion is increased, thus switching a folded state of the actuating portion to an unfolded state;
wherein the control structure further comprises a connecting pipe, and the air bag and the actuating portion are connected through the connecting pipe;
wherein the control structure further comprises a valve, the valve is connected to the connecting pipe, and the valve is configured to let external air enter the connecting pipe and restrict air in the connecting pipe from flowing out;
wherein the valve comprises a valve body and a valve sheet, a valve cavity is arranged in the valve body, the valve body is further defined with an air channel and an air inlet which are both communicated with the valve cavity, a first opening at a first end of the air channel is connected with the connecting pipe, a second end of the air channel is also defined with a second opening, wherein the first end is opposite to the second end, and the second opening is communicated with the valve cavity.
2. The control structure according to claim 1 , wherein the connecting pipe is detachably connected with the actuating portion.
3. The control structure according to claim 1 , wherein one end of one connecting pipe is connected with the actuating portion.
4. The control structure according to claim 1 , wherein the air bag and/or the actuating portion are made of blow-molded plastic or thermoplastic rubber.
5. The control structure according to claim 1 , wherein the volume of the air bag is greater than that of the actuating portion.
6. The control structure according to claim 5 , wherein the volume of the air bag is 4 to 30 times that of the actuating portion.
7. The control structure according to claim 1 , wherein the moving portion is in a hollow flat structure.
8. An ornament, comprising a fabric and the control structure according to claim 1 arranged in the fabric, wherein the fabric comprises a body and a moving structure connected to the body, and the moving portion is arranged in the moving structure.
9. The ornament according to claim 8 , wherein
a limit channel is arranged in the fabric, the connecting pipe of the control structure extends along the limit channel, and the air bag and the actuating portion of the control structure are located outside the limit channel, and located at two ends of the limit channel.
10. The ornament according to claim 8 , wherein the moving portion is located in the moving structure.
