Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific examples, but the embodiments of the invention are not limited thereto.

A foot-operated pneumatic sunshade comprises a base 1; 2. an umbrella rod; 3. a pin hole; 4. An umbrella disk is arranged; 5. a first rib; 6. a second rib; 7. a cylinder; 8. a cylinder fixing frame; 9. An air tube; 10. a pneumatic five-way joint; 11. a pneumatic switch; 12. the air pump is stepped on by foot.

The base 1 is made of marble or cement blocks, and the umbrella rod 2 is vertically fixed at the midpoint of the base 1 through bolts; the lower umbrella disk 4 is sleeved on the umbrella rod 2 and can move up and down along the umbrella rod 2; one end of six or eight first umbrella ribs 5 is hinged on the lower umbrella disc through bolts; one end of a second umbrella rib 6 with the same number as the first umbrella rib is hinged to the top of the umbrella rod 2, and the middle position of the second umbrella rib 6 is hinged to the other end of the first umbrella rib 5; the air cylinder fixing frame 8 is fixed on the umbrella rod 2 by bolts, the tails of a corresponding number of air cylinders 7 are selected according to the size of the umbrella and are hinged on the air cylinder fixing frame 8 by bolts, and the extending movable rods of the air cylinders 7 are hinged on the upper middle position of the second umbrella rib 6;
