[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] The following describes the aerial work safety protective work clothes according to the embodiments of the present invention with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown, an embodiment of the present invention proposes a safety protective work suit for aerial work, comprising: a work suit body 1, a protective airbag and a back box body 2, the front of the work suit body 1 is provided with a zipper 101 for wearing and taking off; the protective airbag is adhered to the outside of the work suit body 1, the protective airbag comprises an upper body airbag 102, two upper limb airbags 103 and two lower limb airbags 104, the upper limb airbags 103 and the lower limb airbags 104 are connected with the upper body airbag 102, the back box body 2 is arranged above the back of the upper body airbag 102, an inflation mechanism is provided in the back box body 2, the inflation mechanism is connected to the protective airbag to inflate the protective airbag, a cushioning airbag is also stored in the back box body 2, the cushioning airbag is connected to the inflation mechanism, an opening 201 is provided on the top of the back box body 2, when the inflation mechanism inflates the cushioning airbag, the cushioning airbag is unfolded at the top opening 201 of the back box body 2 to protect the head and neck of the wearer.

[0027] The embodiment of the present invention provides a protective airbag and a cushioning airbag, and inflates the protective airbag and the cushioning airbag simultaneously through an inflation mechanism, so that the inflated protective airbag surrounds the upper body and limbs of the operator to provide protection and cushioning, thereby reducing injuries caused by falling to the ground, and the inflated cushioning airbag protects the head and neck of the operator to reduce damage to the head and neck.

[0028] Furthermore, the cushioning airbag is in a folded state when stored in the back box 2, which can reduce the storage volume.

[0029] Furthermore, the compressed gas may be a low-density gas, such as helium, nitrogen, etc.

[0030] In some embodiments, Figure 3 As shown, the inflation mechanism includes a compressed gas tank 10, which is connected to the protective airbag and the buffer airbag through a connecting pipe. The connection between the air outlet of the compressed gas tank 10 and the connecting pipe is pluggably connected with a pull rod 12, which is sealingly connected to the air outlet of the compressed gas tank 10. The outer end of the pull rod 12 is fixedly connected to a pull ring 13. When the pull ring 13 is pulled out, the compressed gas tank 10 is connected to the connecting pipe.

[0031] The side wall of the pull rod 12 can completely block the gas outlet of the compressed gas tank 10. The operator pulls the pull ring 13 with force, thereby driving the pull rod 12 to be withdrawn, so that the compressed gas in the compressed gas tank 10 quickly passes into the protective airbag and the buffer airbag.

[0032] Furthermore, the air outlet of the compressed gas tank 10 can be arranged on the side of the compressed gas tank 10, and a rubber sleeve is provided at the end of the pull rod 12, and a sealed connection is formed between the rubber sleeve and the air outlet of the compressed gas tank 10, so that the operator can pull out the pull rod 12 more conveniently from the side.

[0033] In some embodiments, Figure 3 As shown, the connecting pipe includes a first connecting pipe 3 and a second connecting pipe 9, and the gas outlet of the compressed gas tank 10 is connected to the first connecting pipe 3 and the second connecting pipe 9 through a three-way piece 11. The first connecting pipe 3 is connected to the protective airbag, and the second connecting pipe 9 is connected to the buffer airbag.

[0034] It should be noted that the tee 11 has an air inlet connected to the compressed gas tank 10, and an air outlet connected to the first connecting pipe 3 and the second connecting pipe 9 respectively. The diameter of the air outlet of the compressed gas tank 10 is smaller than the air inlet of the tee 11. This is to facilitate the installation of the tie rod 12 so that a sealing barrier is formed between the side wall of the tie rod 12 and the air outlet of the compressed gas tank 10. The internal cavity of the tee 11 forms an air chamber. When the tie rod 12 is pulled out with force, the seal between the tie rod 12 and the compressed gas tank 10 is destroyed, and the compressed gas in the compressed gas tank 10 quickly enters the air chamber and passes into the protective airbag and the buffer airbag.

[0035] In some embodiments, the first connecting tube 3 and the second connecting tube 9 are both hoses. The hose is easy to bend or change direction, and the hose can be left with sufficient length to prevent the connection between the connecting tube and the compressed gas tank 10 from cracking due to the pulling of the work clothes during use, thereby causing air leakage and affecting the protective effect.

[0036] In some embodiments, Figure 4As shown, the pull ring 13 is connected to the pull rope 14, and the end of the pull rope 14 is connected to the lower side of the upper body airbag 102. The pull rod 12 is pulled out by pulling the pull rope 14. The end of the pull rope 14 is arranged at a position that the operator can easily reach, so that the pull rope 14 can be quickly found and pulled in an emergency.

[0037] In some embodiments, Figure 3 As shown, the cushioning airbag includes an O-shaped airbag 7 and a spherical airbag 4. The O-shaped airbag 7 and the spherical airbag 4 are connected. The spherical airbag 4 is located on the back of the O-shaped airbag 7. The O-shaped airbag 7 is a double-layer airbag formed by bending, and the longitudinal section of the O-shaped airbag 7 is O-shaped.

[0038] Furthermore, the O-shaped airbag 7 is connected between the spherical airbag 4 and the compressed gas tank 10 .

[0039] In the initial state, the O-shaped airbag 7 and the spherical airbag 4 are stored in the back box 2 in a folded state. When inflating, the compressed gas in the compressed gas tank 10 first enters the O-shaped airbag 7, causing the O-shaped airbag 7 to expand first. After the O-shaped airbag 7 expands, it drives the spherical airbag 4, which is still in the stored and folded state, to leave the back box 2, and gas is introduced into the spherical airbag 4 to expand the spherical airbag 4.

[0040] In some embodiments, Figure 3 As shown, the O-type airbag 7 is connected to a first exhaust port, to which a first rubber plug 6 is pluggably connected, the spherical airbag 4 is connected to a second exhaust port, to which a second rubber plug 5 is pluggably connected, and the protective airbag is connected to a third exhaust port, to which a third rubber plug is pluggably connected.

[0041] By providing the first exhaust port, the second exhaust port and the third exhaust port, it is convenient to exhaust the protective work clothes after inflation, so that the protective airbag and the cushioning airbag can be reused. By providing a rubber plug at the exhaust port, it is convenient to plug and unplug. When the rubber plug is in the blocking state, a sealed connection is achieved between the rubber plug and the exhaust port to prevent air leakage.

[0042] In some embodiments, a first pressure-limiting valve is connected to a connection between the first connecting tube 3 and the protective airbag, and a second pressure-limiting valve is connected to a connection between the second connecting tube 9 and the buffer airbag.

[0043] By providing the first pressure-limiting valve and the second pressure-limiting valve, exhaust can be performed when the set pressure in the protective airbag and the buffer airbag is reached to prevent explosion.

[0044] In some embodiments, the compressed gas tank 10 is detachably connected to the back box 2, so that the compressed gas tank 10 can be easily replaced.

[0045] Furthermore, the detachable connection between the compressed gas tank 10 and the back box 2 may be a bolt connection or a snap connection.

[0046] In some embodiments, Figure 3 As shown, a buffer block 8 is connected to the upper part of the back box 2, and the buffer block 8 is arranged at the edge of the opening 201 to squeeze the O-type airbag 7. By providing the buffer block 8, the O-type airbag 7 can be pushed against the head of the operator after expansion, thereby improving the protection effect.

[0047] Furthermore, the buffer block 8 is a latex block or a rubber block or a spring plate structure.
