Hydraulically Supported Umbrella

Abstract

The invention discloses a hydraulic supporting umbrella comprising an umbrella fabric, an umbrella stand, an umbrella pole and a gripping handle, wherein the umbrella pole comprises a hydraulic cylinder, a rotating drum and a telescopic rod; the top end of the hydraulic cylinder is provided with a rotary sealing cover, the rotary sealing cover is connected with the top of the umbrella fabric, a plurality of pipe joints are uniformly distributed at the upper corner of the circumferential surface close to the upper end of the hydraulic cylinder, an inner screw is arranged on the pipe wall at the lower section inside a cylinder barrel, and a piston is arranged at the upper section inside the cylinder barrel; the top of the rotating drum is movably connected with the bottom of the piston; an outer screw is arranged at the periphery of the upper section of the rotating drum and is matched and rotationally connected with the inner screw; the telescopic rod is movably inserted to the inside of the rotating drum; the umbrella stand comprises a plurality of stripped-bag-shaped hydraulic hose bags detachably connected with the hydraulic cylinder in a sealing way through the corresponding pipe joints; a plurality of ferrules are uniformly distributed at the middle corner of the umbrella fabric; a plurality of bottom-sealed bags are uniformly distributed along the corner of the lower circumference at the bottom of the umbrella; and the ferrules are sleeved by the middles of the hydraulic hose bags, and the bags are sleeved and inserted by the bottoms of the hydraulic hose bags. The hydraulic supporting umbrella is relatively small in size, low in maintaining cost, convenient to maintain and more convenient to use.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and relates to umbrellas, in particular to hydraulically supported umbrellas. Background technique [0002] The traditional umbrella structure can be summarized as follows: including the umbrella surface that is conical cover-shaped body after opening in place, the foldable umbrella stand device that supports the umbrella surface laterally, and the retractable umbrella that supports the umbrella surface and the umbrella stand device vertically. Rod device, the handle that is located at the bottom of the umbrella rod device. The umbrella stand devices are hinged multiple thin rod-shaped bodies, which are easy to bend or even break, and the hinged joints are also easy to fall off. The failure rate is high and maintenance is troublesome, so people thought of using a new inflatable umbrella. structure to replace the traditional umbrella stand structure. [0003] For example: the authorize...

Problems solved by technology

[0004] The inflatable umbrella using this technology can of course be used, and it also overcomes the shortcomings of the traditional thin rod hinged umbrella frame structure. However, due to the high compressibility of the gas, the support ribs formed after inflating can have a certain strength to support the umbrella. On the surface, the air pressure needs to be high, and the size of the inflatable support ribs must be large enough, so the umbrella volume is relatively large; due to the air tightness requirements of the gas, the accuracy requirements of the relevant structural parts are relatively high, and the entire umbrella surface including the support ribs It is a whole, and one air leak is completely scrapped, so the maintenance is inconvenient and the maintenance cost is high; since there is only an inflation nozzle, the realization of inflation must be provided by another inflation device, the inflation is not convenient enough, and the use effect is not enough ideal
