The upright sleeve 136 on the outer upright rod 11 functions as a limit sliding portion 137 and an inner telescopic rod 12.

A Roman umbrella with a retractable umbrella surface structure includes a base 2, an umbrella surface assembly 3 and the above-mentioned pole assembly 1, and the base 2 is fixedly connected to the bottom of the outer pole 11. The umbrella surface assembly 3 includes an upper umbrella plate 301, a lower umbrella plate 302, an umbrella rotatably connected to the upper umbrella plate 301 and the lower umbrella plate 302, an umbrella surface 306 disposed between the umbrella bones, a first cross bar 303 and a first Two cross bars 304, there are multiple sets of umbrella bones, the first cross bar 303 is hinged at one end with the lower umbrella pan 302, the other end is hinged with the inner telescopic rod 12, the second cross rod 304 is hinged at one end with the upper umbrella pan 301, and the other end is sliding The portion 137 is hinged, and the first cross bar 303 and the middle of the second cross bar 304 are cross hinged.

Working principle: Press the up button of the remote control 106, the power passes through the control circuit 104, the motor 103 rotates clockwise, driving the worm 117 to rotate, the worm 117 simultaneously drives the worm wheel 116 to rotate, further decelerating and increasing torque, the worm wheel 116 and the rope wheel 113 pass through the rotating shaft 118 and the flat key 119 are connected together, and the sheave 113 rotates with the worm gear 116. Because the traction rope 114 located near the sheave 113 is pressed with a traction rope chuck 115 and fixed to the traction rope of the sheave 113 with a large flat head screw 123 In the groove, the traction rope 114 is wound on the sheave 113, one end is wound inward, and the other end is wound outward. The sheave 113 drives the traction rope 114 on the sheave 113 to rotate. Whether it is forward or reverse, the length of the traction rope is always the same. A traction rope chuck 115 is also pressed on the traction rope 114 at the lower end of the inner telescopic rod 12, and is fixed on the inner telescopic rod 12 by screws with a pressing member 134 to connect them together. At the same time, the two ends of the traction rope 114 respectively pass through the traction rope screws 138 and press the traction rope chuck 115, and are connected to the sliding portion 137. The motor 103 rotates clockwise, driving the rotating mechanism 13 to rotate, pulling the traction rope 114, pulling the inner telescopic rod 12 downward through the upper guide wheel 133A and the lower guide wheel 133B, and pulling up, between the top piece 135 and the sliding part 137 The distance becomes smaller. At the same time, through the first cross bar 303, the second cross bar 304, the pin 305, the upper umbrella plate 301 and the lower umbrella plate 302, the umbrella surface 306 is opened at the same time. Specifically, the top piece 135 and the sliding portion 137 drive the first cross bar 303 and the second cross bar 304 to fold, so that the distance between the upper umbrella tray 301 and the lower umbrella tray 302 becomes smaller, and the umbrella tray drives the umbrella bones to open the umbrella surface to open . When retracting the umbrella, in the same way, the rotating mechanism 13 drives the traction rope 114 to rotate clockwise. The traction rope 114 drives the inner telescopic rod 12 to move up and the sliding portion 137 to move down, so that the umbrella surface assembly 3 is gathered, and during the gathering process The position of the middle and upper umbrella tray 301 moves up correspondingly. Obviously, in the method adopted in the prior art to collect the umbrella by moving the lower umbrella tray up, the height of the upper umbrella tray is fixed and the upper umbrella in the present invention The position of the tray 301 moves upwards during the umbrella collection, thereby raising the height of the entire umbrella assembly 3, so that it is not easy to touch the table under the umbrella and the things on the table. At the same time, this structure does not need to increase the height of the umbrella edge. The sunshade effect is not good because the umbrella edge is too high.

Example 2

Embodiment 2 On the basis of Embodiment 1, the rotating mechanism 13 is changed to a manual rotating mechanism, and the rest of the structure is the same as that of Embodiment 1. The rotating mechanism 13 includes a traction rope winding drum and a rocker 139 fixedly connected to the traction rope winding drum The traction rope winding drum and the swinging hand 139 are both conventional wire rope winding structures. The working process and working principle of Embodiment 2 are also similar to those of Embodiment 1, except that the electric drive is replaced manually.
