The fixing principle of the adjacent canopy 101 is as follows: one of the arc-shaped side edges of two adjacent umbrellas 101 is attached, and the upper end and the lower end of each canopy 101 are aligned; the arc-shaped side edge of the canopy 101 is turned inwards twice to form a seaming area with the width of one centimeter, the connecting belt 400 is covered on the seam, and the seaming areas on the left side and the right side of the connecting cover are covered; temporarily fixing the two pieces of canopy 101 and the connecting band 400 by using an adhesive tape; the connecting band 400 is sewn to the seam area of the two pieces of the canopy 101 using machine sewing. In the above machine sewing process, preferably, the sewn stitch is a Z-shaped sewn stitch.

The number of the connection bands 400 is half of the number of the canopy 101, and the length of the connection bands 400 is more than twice the length of the arc-shaped sides of the canopy 101. The 2N pieces of the canopy 101 are combined to form 2N seams, wherein every two seams are butted against each other, the connecting band 400 covers the butted two seams, and the connecting band 400 connects the four pieces of the canopy 101 to each other by sewing. The 2N pieces of umbrella cover 101 are connected with each other by the connecting belt 400 to form the complete umbrella body 100.

As shown in fig. 4, the supporting member 300 is fixed to the lower end of the umbrella body 100, and serves to increase the overall structural strength of the umbrella body 100, shorten the opening time of the umbrella body 100, and improve safety. The lower edge of the umbrella body 100 is folded upwards and sewed to form a ring-shaped supporting cavity, and the supporting member 300 is inserted into the supporting cavity. The ends of the supporting member 300 are fixed to each other by the connecting member 500.

Preferably, in this embodiment, the connecting member 500 is a metal round pipe, the inner diameter of the metal round pipe is equal to or slightly smaller than the diameter of the supporting member 300, and two ends of the supporting member 300 are inserted into the metal round pipe in a transition or interference manner.

The supporting piece 300 is made of glass fiber materials, the glass fiber has the characteristics of high strength, high modulus and high flexibility, the single fiber tensile strength of the supporting piece is 2800MPa, and the elastic modulus of the supporting piece is 86000 MPa. The strength of the whole structure of the umbrella body 100 can be obviously improved, the umbrella body 100 can be opened rapidly when in use, and the time for opening the umbrella can be shortened.

As shown in fig. 1 and 5, an umbrella cord 200 is fixed to a lower edge of the umbrella body 100, and an end of the umbrella cord 200, which is away from the umbrella body 100, is used to fix an evacuee. The number of the umbrella ropes 200 is N, both ends of the umbrella ropes 200 are respectively connected to the lower ends of the two opposite umbrella covers 101, and the middle parts of the umbrella ropes 200 are fixed on the escape personnel. Both ends of the umbrella cord 200 are preferably fixed at the seams of the two opposite umbrellas 101, the umbrella cord 200 covers both ends of the connecting band 400, and the umbrella cord 200, the connecting band 400 and the two adjacent umbrellas 101 are fixed to each other by sewing.

The middle part of the umbrella rope 200 and a part of the umbrella rope 200 far away from the umbrella body 100 are integrated into a fixed bundle, and a heat-shrinkable tube 600 is sleeved outside the fixed bundle. The heat shrinkable tube 600 contains the N umbrella ropes 200 into one bundle, so that the umbrella ropes 200 can be conveniently fixed on the life of the person to be escaped, and meanwhile, the uniformity of the tension applied to the umbrella body 100 is ensured. The portion of the umbrella string 200 outside the heat shrinkable tube 600 forms a fixing buckle 201, and the fixing buckle 201 is used for being fixed on the escape person. In this embodiment, the experimental weight 700 is used to simulate an evacuee, a protruding fixing portion 701 is disposed on the experimental weight 700, and the fixing buckle 201 is fastened to the fixing portion 701 on the experimental weight 700.

In order to ensure the safety, the length of the umbrella rope 200 is generally set to be 2-4 times of the diameter of the umbrella body 100. Preferably, the length L of the parasol line 200, the length S of the parasol line 200 fixed to the canopy 101, and the diameter of the umbrella body 100 satisfy the following relationship: l ═ 2.25 × (D + S). The length S of the umbrella cord 200 fixed to the canopy 101 can be selected according to the diameter D of the umbrella body 100, wherein the sewing length S is preferably larger for larger diameters D of the umbrella body 100 and smaller for smaller diameters of the umbrella body 100. In this embodiment, the diameter D of the umbrella body 100 is 2.5m, and the suture length S is 9% of D, so that L is 2.25 (2.5+2.5 0.09) and 6.131 m.

In this embodiment, two adjacent umbrellas 101 are sprayed with different colors, for example, two adjacent umbrellas 101 are sprayed with blue and red colors, respectively. Canopy 101 is made of high strength nylon material to reduce overall cost while ensuring safety, enabling common salary classes to consume.
