Problems solved by technology

[0007] For this reason, the first technical problem to be solved by the present invention is that when deformed umbrellas in the prior art run into bad weather such as heavy rainfall, rainwater will fall to the ground along the umbrella surface, making the ground at the bottom of the umbrella become slippery, affecting The problem of working under the umbrella; and then provide a giant umbrella that can ensure that the ground is dry and will not affect the work under the umbrella by adjusting the rotation angle of the umbrella pole along the vertical direction of the support tube and the hinged end of the umbrella pole.
[0009] The third technical problem to be solved by the present invention is that the diameters of the two ends of the umbrella pole of the deformable umbrella in the prior art are the same, which causes the umbrella rope to bear a large load and the umbrella body is easy to deform. A portable deformable umbrella whose diameter from the pipe connection end to the other end of the umbrella pole changes from large to small

Embodiment 1

[0037]The giant umbrella of the present invention includes a support tube 1, an umbrella pole 2, and a tension connector. In this embodiment, the tension connector is a stay rope 3, and one end of the stay rope 3 passes through the support tube 1 The support point at the top is connected with the support tube 1, and the other end is hinged with the umbrella pole 2, and the hinged end of the support tube 1 and the umbrella pole 2 is vertically lower than the support point at the top of the support tube 1, In addition, the rotation angle of the umbrella pole along the support tube and the hinged end of the umbrella pole in the vertical direction is any angle between 0° and 180°, and the rotation angle is preferably set at 0° to 110°.

[0038] In view of the special structure of the above-mentioned giant umbrella in use, when encountering rainy weather, adjust the above-mentioned angle within the range of less than 90 degrees, that is to say, the hinged end of the support tube and...

Embodiment 2

[0040] In this embodiment, when other conditions remain unchanged in Embodiment 1, a drainage channel is further provided in the support tube 1, corresponding to the hinge joint between the support tube 1 and the umbrella pole 2, in the support tube 1 A water inlet connected with the drainage channel is arranged on the top.

[0041] After the giant umbrella is set with drainage pipes, when it is used in rainy weather, due to the special "V" structure when the giant umbrella is opened, the raindrops that fall on the top of the giant umbrella will collect at the top of the giant umbrella near the support pipe 1, and the collected rainwater Through the water inlet arranged on the support pipe 1, it flows into the drainage channel inside the support pipe 1, and finally the rainwater is drained away through the underground drain. The giant umbrella with the above structure ensures the drying of the work area at the bottom of the umbrella, so that the work under the umbrella can be ...

Embodiment 3

[0045] On the basis of the giant umbrellas described in Embodiment 1 and Embodiment 2, the giant umbrella described in this embodiment is further provided with a sliding disk 5 connected to the top of the support tube 1, and the sliding disk has a hollow space. The cavity is cylindrical, an arc-shaped protrusion extending toward the outer cylindrical wall is provided at the top of the cylindrical shape, and an arc-shaped protrusion extending toward the outer cylindrical wall of the sliding disc is provided between the outer cylindrical wall with a cavity. There are ribs. A tension connector driving device is arranged inside the support tube 1 , and the tension connector driving device includes an oil cylinder, a piston and a power source for driving the piston to make reciprocating linear motion along the axis of the support tube 1 . One end of the stay rope 3 connected to the support tube 1 is connected to the moving end of the tension connector driving device after bypassing...

Abstract

A large-sized umbrella comprises a support tube, umbrella rods and tension connectors, wherein the support tube is hinged to the umbrella rods, one end of each tension connector is connected with the support tube through a support point at the top end of the support tube, the other end of each tension connector is hinged to the corresponding umbrella rod, and the hinging end for the support tube and the umbrella rods is lower than the support point at the top end of the support tube in the vertical direction and is lower than the other end of each umbrella rod in the vertical direction. A drainage passage is reserved in the support tube, and at least one water inlet communicated with the drainage passage is disposed on the support tube and corresponds to the hinged position of the support tube with the umbrella rods. The large-sized umbrella has the advantages that the large-sized umbrella is simple in operation, dryness of the bottom of the large-sized umbrella is guaranteed, the height of a body of the large-sized umbrella is adjustable, the large-sized umbrella is long in service life and the like.

Description

technical field [0001] The invention relates to a giant umbrella, in particular to a giant sunshade and rainproof umbrella which is easy to disassemble and assemble, and belongs to the construction field. Background technique [0002] With the development of society, some large stadiums, entrance corridors, public leisure and entertainment plazas, exhibition venues, shopping centers and other places often require large-scale, long-term open-air construction. When these construction sites encounter strong rain or snowstorm, Since the construction site cannot be effectively covered, the construction work cannot be carried out normally, thereby affecting the construction process. At present, in large-scale construction sites, it is usually to build a large-scale construction shed and work in the construction shed. Promptly disclose a kind of ultra-high large beamless and column-free engineering greenhouse as Chinese patent CN1136120A, the appearance of this engineering greenho...
