[0016] Fig. 3 It is the lower view of the utility model. DETAILED DESCRIPTION

[0017] In order to further describe the technical features and effects of the utility model, the utility model is further described below in combination with the drawings and specific embodiments.

[0018] As Figs. 1-3 Indicated, the utility model discloses a kind of back plate special for gas supply bottle, including back plate main body 1, two upper back belt holes 2 are symmetrically set in the upper of back plate main body 1, two lower back belt holes 3 are symmetrically set in the back plate main body 1 below upper back belt hole 2, two gas supply bottle binding holes 4 are symmetrically set in the back plate main body 1 between upper back belt hole 2 and lower back belt hole 3, emergency switching valve fixing position 5 and main gas path air inlet valve fixing position 6 are respectively arranged in the left and right sides of the back plate main body 1 below lower back belt hole 3, emergency gas supply valve fixing position 7 is arranged below main gas path air inlet valve fixing position 6.

[0019] To further fix gas supply bottle, auxiliary binding hole 8 for binding gas supply bottle cover is arranged on the back plate main body 1 between two upper back belt holes 2.

[0020] To facilitate wearing some gas supply and some auxiliary equipment in construction process so that the pipeline of these equipment passes through binding, first threading hole 9 is arranged on the back plate main body between two lower back belt holes 3, second threading hole 10 is arranged on the back plate main body below first threading hole 9.

[0021] To further increase the stability when wearing back plate, two waist belt holes 11 are symmetrically arranged on the outer side of the back plate main body 1 below emergency switching valve fixing position 5 and main gas path air inlet valve fixing position 6.

[0022] In order to further fix the gas cylinder on the back plate, two gas cylinder auxiliary binding belt holes 12 are symmetrically arranged on the back plate body 1 on both sides of the second threading hole 10.

[0023] In order to increase the stability of the back plate in the state of being carried on the back, the two upper back belt holes 2 are arranged in the shape of an "eight" on the back plate body 1, which can better fit the back belt in the state of being carried on the back.

[0024] In order to prevent the emergency switching valve, the main gas path air inlet valve and the emergency gas supply valve from shaking and to support the gas cylinder, threaded holes 13 adapted to the fixing bolts are arranged on the emergency switching valve fixing position 5, the main gas path air inlet valve fixing position 6 and the emergency gas supply valve fixing position 7.

[0025] In order to increase the stability of the gas cylinder on the back plate and prevent the gas cylinder from shaking, upper clamping brackets 14 adapted to the outer shell of the gas cylinder are arranged on the back plate body 1 between the two upper back belt holes 2, and lower clamping brackets 15 adapted to the outer shell of the gas cylinder are arranged between the two lower back belt holes 3.

[0026] In use, one back belt can be arranged on each side of the back plate body 1 to pass through the upper back belt hole 2 and the lower back belt hole 3 on the same side to form a closed loop for the operator to carry on the back. After the gas cylinder is arranged in the gas cylinder cover, the opening of the gas cylinder cover is tied up (the valves are exposed outside), the gas cylinder is arranged on the back plate with the head facing downward (the valves are below), the emergency switching valve, the main gas path air inlet valve and the emergency gas supply valve are fixed on the emergency switching valve fixing position 5, the main gas path air inlet valve fixing position 6 and the emergency gas supply valve fixing position 7 through bolts, the connection between the valves and the gas cylinder is achieved by using relatively hard rubber pipes, the gas cylinder can be supported, and the gas cylinder is bound on the back plate body 1 by passing a binding belt through the two gas cylinder binding belt holes 4 and the two gas cylinder auxiliary binding belt holes 12. In case the gas cylinder falls, the rope sleeve at the bottom of the gas cylinder cover is bound with the auxiliary binding hole 8 of the gas cylinder cover to further fix the gas cylinder. At this time, the operator can easily carry the back plate with the gas cylinder on the back, which is stable and reliable.

[0027] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto, any change or replacement without creative labor is covered in the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
