[0038] Embodiment 2

[0039] In a specific embodiment provided by the present utility model, as Figures 1-3 shown, the frame structure 1 of the utility model is a framework. The basket structure 2 is fixedly connected to the middle of the vehicle body 101. The connecting rod 201 inside the basket structure 2 is welded to both sides of the vehicle body 101. A fixed valve is provided below the connecting rod 201. The load-bearing rod 202 is detachably connected to the connecting rod 201 through the fixed valve. The load-bearing rod 202 is a soft strip structure and the length of the load-bearing rod 202 is adjustable. The soft structure can change its shape according to the force condition, which is convenient for transporting irregular gas cylinders.

[0040] Embodiment 3

[0041] In a specific embodiment provided by the present utility model, as Figures 4-6 shown, the basket structure 2 in Embodiment 1 is changed. Positioning frames are installed on both sides of the vehicle body 101. The arc-shaped side cover plate 208 with a central angle of 90° - 150° passes through the positioning frame and is hinged to the rotating shaft 206, so that the side cover plate 208 can change its direction with the movement of the rotating shaft 206. A spring frame 205 is vertically installed on the side of the rotating shaft 206. A push rod 207 is fixedly connected to the top of the rotating shaft 206. A support plate 204 is installed at the top end of the spring frame 205. When no gas cylinder is loaded in the gas cylinder vehicle, the side cover plate 208 is in a "W" shape. At the same time, since a clamping block 210 is provided on the outer side of the side cover plate 208, the side cover plate 208 is limited by the positioning frame and will not fall out of the gas cylinder vehicle;

[0042] When a gas cylinder is loaded in the gas cylinder vehicle, during the transportation of the gas cylinder vehicle, manually push the push rod 207. After putting the gas cylinder in, the gas cylinder presses on the support plate 204 backward. The support plate 204 pushes the spring frame 205 to compress and drives the rotating shaft 206 to move backward. One side of the side cover plate 208 is subjected to the backward acting force of the rotating shaft 206 to change its direction and clamp the gas cylinder. Since the spring frame 205 contracts and continuously applies pressure to the rotating shaft 206, the gas cylinder is stably clamped and will not be affected by the road conditions to clamp the gas cylinder. After the gas cylinder is delivered to the designated location, manually push the push rod 207. The push rod 207 drives the rotating shaft 206 to move forward and applies a forward acting force to the spring frame 205. The rotating shaft 206 simultaneously drives one side of the side cover plate 208 to move forward, and the side cover plate 208 cancels the clamping of the gas cylinder.
