[0002] A gas cylinder is a container for storing gas, which generally contains compressed or liquefied gas. Therefore, the gas cylinder needs to be strong enough to withstand the high pressure of the gas during use. For this reason, gas cylinders are more or less dangerous and require special attention during transportation, handling and use.

[0003] Storing gas inside gas cylinders is not only convenient for use, but also for transportation. In real life, gas cylinders are generally placed in the compartments of vehicles for transportation. However, the bumps during vehicle transportation can easily cause collisions between gas cylinders, increasing the danger of the gas cylinders.

[0004] In the prior art, collisions are avoided and friction is reduced by fixing gas cylinders, such as a gas cylinder container with a buffer and anti-collision function disclosed in publication number CN217199191U. This fixing method reduces friction by limiting the movement of gas cylinders. However, in actual use, if the gas cylinders are fixed too tightly, they are easily damaged. If they are fixed too loosely, they are easy to loosen, and the anti-friction effect is poor. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 5 As shown, the utility model provides a gas cylinder anti-collision protection structure, comprising a fixing plate 1, a plurality of hollow sleeves 2 are fixedly arranged at the bottom end of the fixing plate 1, the top end of the hollow sleeve 2 penetrates the fixing plate 1, and an annular air bag 10 capable of fixing the gas cylinder is fixedly arranged on the inner wall of the hollow sleeve 2;

[0025] A bellows 7 and a second spring 8 are fixedly provided at the bottom end of the hollow sleeve 2, and the second spring 8 is located at the outer end of the bellows 7. A bottom plate 12 is fixedly provided at the bottom end of the bellows 7, and the bottom end of the second spring 8 is fixedly connected to the top end of the bottom plate 12. A plurality of balls 13 are fixedly provided at the top end of the bottom plate 12, and the balls 13 are located inside the bellows 7. A first anti-slip pad is fixedly provided at the bottom end of the bottom plate 12, and the first anti-slip pad is in close contact with the bottom end of the interior of the vehicle.

[0026] The fixing plate 1 is fixed horizontally inside the car, and the second spring 8 is in a compressed state. The elastic force of the second spring 8 pushes the bottom plate 12 downward, and makes the first anti-skid pad at the bottom end of the bottom plate 12 closely contact with the bottom end of the car. Then the gas cylinder is placed vertically inside the hollow sleeve 2, and the lower half of the gas cylinder enters the bellows 7, and the bottom end of the gas cylinder contacts the ball 13. Then, air is inflated into the annular airbag 10. After the annular airbag 10 is expanded, the gas cylinder is properly clamped and fixed inside the hollow sleeve 2. Each gas cylinder is distributed in a different hollow sleeve 2 and is fixed by the annular airbag 10, so there will be no collision between the gas cylinders. The bottom end of the gas cylinder contacts the ball 13. Even if the bottom end of the gas cylinder slides during movement, it will only cause the ball 13 to roll. In this way, the sliding friction is converted into rolling friction, and it can play an anti-friction role without fixing the gas cylinder too tightly, thereby improving the anti-friction effect.

[0027] The fixing tightness of each gas cylinder is consistent, such as Figure 1-Figure 3 As shown, a plurality of connecting tubes 11 are fixedly provided on the inner wall of the hollow sleeve 2, and the two ends of the connecting tubes 11 are respectively connected with the cavity in the wall of the hollow sleeve 2 and the annular airbag 10, so as to input air into the annular airbag 10 for inflation.

[0028] An air delivery channel 9 is provided between any two adjacent hollow sleeves 2, and the cavities of the two adjacent hollow sleeves 2 are connected through the air delivery channel 9, and the air delivery channel 9 is fixed at the bottom end of the fixed plate 1. Under the connection of the air delivery channel 9, all the annular airbags 10 are interconnected;

[0029] Air is input into the gas delivery channel 9. Under the connection of the gas delivery channel 9, the cavities of each hollow sleeve 2 are interconnected. The air entering the gas delivery channel 9 then enters the cavity of the hollow sleeve 2 and finally enters the annular airbag 10 through the connecting pipe 11, thereby inflating the interior of the annular airbag 10. All gas cylinders can be fixed at the same time, and the fixing force of each gas cylinder is the same.

[0030] In order to check the fixing strength of the gas cylinder, Figure 1 , Figure 5 As shown, a pneumatic assembly 3 is provided at the top of the fixed plate 1, and the pneumatic assembly 3 includes a transparent scale tube 301 fixed at the top of the fixed plate 1, and a through tube 302 is fixed at one end of the transparent scale tube 301, and one end of the through tube 302 extends to the bottom of the fixed plate 1 and is fixedly connected to one of the gas delivery channels 9.

[0031] The other end of the transparent graduated tube 301 is provided with a detachable end cap 303, and a movable plug 304 is provided inside the transparent graduated tube 301. A sealing gasket in contact with the inner wall of the transparent graduated tube 301 is fixed at the outer end of the movable plug 304. The position of the movable plug 304 inside the transparent graduated tube 301 can be used to judge the air pressure.

[0032] A first spring 306 and an air pipe 305 are provided between the movable plug 304 and the end cover 303 . The two ends of the first spring 306 are fixedly connected to the end cover 303 and the movable plug 304 , respectively. The two ends of the air pipe 305 pass through the movable plug 304 and the end cover 303 , respectively. A valve is fixedly provided on the air pipe 305 .

[0033] Open the valve on the gas supply pipe 305, and inflate the transparent graduated tube 301 through the gas supply pipe 305. The air entering the transparent graduated tube 301 then enters the gas supply channel 9 through the through-tube 302, thereby inflating the gas supply channel 9 and the annular airbag 10. As the air pressure increases, the movable plug 304 is pushed inside the transparent graduated tube 301, and the first spring 306 is compressed. By observing the position of the movable plug 304 inside the transparent graduated tube 301 in combination with the scale on the transparent graduated tube 301, the air pressure inside the transparent graduated tube 301 and the annular airbag 10 connected to the transparent graduated tube 301 can be understood, and then the fixing force of the gas cylinder can be understood and controlled.

[0034] The protective structure can be detachably installed in the vehicle for transporting gas cylinders, such as Figure 1 As shown, end rods 4 are fixedly provided at both ends of the fixing plate 1, sleeves 5 are provided at both ends of the end rods 4 through threaded sleeves, an extrusion plate 6 is provided at one end of the sleeve 5 away from the end rod 4 through a bearing, and a second anti-slip pad is fixedly provided on the side of the extrusion plate 6 away from the sleeve 5, thereby fixing the structure inside the car.

[0035] Place the fixing plate 1 horizontally in the carriage, rotate the sleeve 5 to move the sleeve 5 on the end rod 4, and make the extrusion plate 6 gradually approach the side wall of the carriage until the second anti-skid pad contacts the side wall of the carriage, continue to rotate the sleeve 5, tighten the sleeve 5 so that the extrusion plate 6 and the second anti-skid pad are pressed against the side wall of the carriage, the end rod 4 is thus stuck in the carriage, and the fixing plate 1 is also installed in the carriage, and the installation height of the fixing plate 1 is controlled during installation so that the second spring 8 at the bottom of the fixing plate 1 is in a compressed state.
