[0032] Such as Figure 1 and 2As shown, in an embodiment of the present utility model, the inflatable air bridge structure includes a floating bridge inflatable body 1, a floating bridge support body 4, a locking member 2, and a connecting member 3. An inflation inner cavity 11 is provided in the floating bridge inflatable body 1. The floating bridge support body 4 is connected to the upper surface of the floating bridge inflatable body 1. The number of the locking members 2 corresponds to the number of the connecting members 3. The locking members 2 and the connecting members 3 are oppositely arranged at at least two side ends of the floating bridge inflatable body 1. And when at least two floating bridge inflatable bodies 1 are assembled into one body, the locking member 2 of one floating bridge inflatable body 1 is detachably connected to the connecting member 3 of the adjacent floating bridge inflatable body 1. Among them, the number of the inflation inner cavities 11 is one, that is, the floating bridge inflatable body 1 is an inflation structure.

[0033] Through the technical solution of the present utility model, by adopting multiple groups of locking members 2 and connecting members 3 along at least two side ends (i.e., the upper and lower and / or front and rear side ends) of the floating bridge inflatable body 1, rapid assembly in multiple directions of the floating bridge inflatable body 1 can be realized, and the stability of the whole formed by the assembly can be ensured, and the safety and stability in use can be improved. Further, through the floating bridge support body 4, the stress directly applied to the floating bridge inflatable body 1 can be reduced, so as to reduce phenomena such as loss of the floating bridge inflatable body 1, thereby improving the overall structural stability of the floating bridge inflatable body 1 and ensuring the safety in use.

[0034] Among them, in some embodiments, such as Figure 1 and 2 As shown, the number of the locking members 2 is the same as the number of the connecting members 3. And the number of the locking members 2 is at least two and they are respectively arranged on the front side and / or the rear side and / or the upper side and / or the lower side of the floating bridge inflatable body 1. The number of the connecting members 3 is at least two and they are respectively arranged on the front side and / or the rear side and / or the upper side and / or the lower side of the floating bridge inflatable body 1. Further, as Figure 1 shown, the locking members 2 are respectively arranged on the rear side and the upper side of the floating bridge inflatable body 1. The connecting members 3 are respectively arranged on the front side and the lower side of the floating bridge inflatable body 1 (wherein, as Figure 1 shown, the front side in the forward or backward direction of the inflatable air bridge structure is the right side or the left side). This structure realizes the lateral expansion area and the longitudinal extension length through rapid assembly operations from four directions of front, back, up, and down, thereby enhancing the load-bearing capacity, greatly increasing the number of rescued people, and improving the rescue material transportation efficiency.

[0035] Specifically, in some embodiments, such as Figure 1 and 2As shown in the figure, the pontoon bridge support 4 includes a waterproof support plate 41, an anti-slip layer 42 and a reflective layer 43; the waterproof support plate 41 and the anti-slip layer 42 are stacked; and the waterproof support plate 41 is connected to the surface of the pontoon bridge inflatable body 1; the reflective layer 43 is connected to the surface of the waterproof support plate 41 and / or the surface of the anti-slip layer 42. Among them, the waterproof support plate 41 is a waterproof plate made of materials such as EVA (ethylene-vinyl acetate copolymer), HDPE (high density polyethylene), LDPE (low density polyethylene), LLDPE (linear low density polyethylene), etc.; the anti-slip layer 42 is an anti-slip layer made of materials such as rubber or EVA (ethylene-vinyl acetate copolymer); the reflective layer 43 is a reflective fabric, reflective ribbon, reflective silk, reflective cloth, reflective leather, reflective lattice tape, etc. This structure can reduce the absorption of the support layer by the waterproof support plate 41 and increase the overall weight; it can also ensure the riding safety of the rescued personnel and staff through the anti-slip layer 42 to avoid falling into the water; and through the reflective effect of the reflective layer 43, it can ensure that the rescue personnel in non-water areas can quickly search for the existence of the air bridge structure, improving the rescue speed and efficiency.

Among them, the first connecting ring 32 and the locking buckle 21 are disposed opposite to the front and rear ends of the pontoon bridge inflatable body 1; since the stress on the front and rear ends of the pontoon bridge inflatable body 1 is relatively greater than the swinging stress on the left and right ends during driving, the overall stress effect is improved by the way of buckling and assembling the first connecting ring 32 and the locking buckle 21, thereby improving the stability of the structure and the safety of use.

Further, the first ring 321 is a circular ring or a square ring, etc. When at least two pontoon inflatable bodies 1 are assembled, the first ring 321 of one pontoon inflatable body 1 is assembled into the locking inner cavity 213, thereby improving the rapidity of operation and the rescue speed. In addition, this structure can use the first folding hook body 211 and the first ring 321 to be towed forward at a maximum speed of 8 kilometers per hour behind other motor boats, improving the operating boundary line and use safety.

[0038] Specifically, in some embodiments, as Figure 1 and 2 shown, the locking member 2 further includes at least one locking belt 22; the connecting member 3 includes a second connecting ring 31 corresponding to the locking belt 22; and the locking belt 22 and the second connecting ring 31 are oppositely arranged on both side ends of the pontoon inflatable body 1; when at least two pontoon inflatable bodies 1 are assembled, the locking belt 22 of one pontoon inflatable body 1 is detachably connected to the second connecting ring 31 of the adjacent pontoon inflatable body 1. Among them, as Figure 1 shown, the locking belt 22 and the second connecting ring 31 are oppositely arranged on the upper and lower side ends of the pontoon inflatable body 1. Since during the driving process, the stress received at the front and rear ends of the pontoon inflatable body 1 is relatively greater than the swinging stress at the left and right ends, the overall stress effect can be guaranteed through the way of tying and assembling the locking belt 22 and the second connecting ring 31, thereby improving the structural stability and use safety. Among them, in some embodiments, as Figure 3 and 4 shown, the locking belt 22 includes a third connecting block 222 and a locking binding rope 221 that are connected to each other; and the third connecting block 222 is connected to the pontoon inflatable body 1; the locking binding rope 221 is detachably connected to the second connecting ring 31. In some embodiments, as Figure 3 and 4 shown, the second connecting ring 31 includes a fourth connecting block 311 and a second ring 312 that are connected to each other; and the second ring 312 is detachably connected to the locking belt 22 (the locking binding rope 221 therein).

Further, as Figure 5 shows, a first connection inner cavity 74 is provided in the support block 73; the support ring member 75 is a support circular ring or a support square ring; the support straight member 72 is a support rod or a support rope; the support rod or the support rope passes through the first connection inner cavity 74 and is disposed around the side surface of the floating bridge inflatable body 1; and one of the support rod or the support rope is used to be adhesively bonded or sewn to the first connection block 214, the third connection block 222, the second connection block 322 and the fourth connection block 311 respectively; thereby further improving the assembly stability of the locking member 2 and the connecting member 3.

[0040] Specifically, in some embodiments, as Figure 4 and 5 show, an anchoring ring 33 is further provided at the side end of the floating bridge inflatable body 1. Through the anchoring ring 33, the stability of docking can be ensured and the safety of use can be improved.
