The second fixed plate 7 is rotatably connected to two rotating frames 6 on the opposite side walls through a pin shaft. The lower surfaces of the two rotating frames 6 are fixedly connected to the hydraulic lifting rod 5. The lower surfaces of the two hydraulic lifting rods 5 are commonly fixedly connected to the second connecting rod 8. Two auxiliary wheels 9 are arranged on the second connecting rod 8. After the gas cylinder is fixed, the handle frame 1 is pressed down to make the first fixing plate 2 of the bottom support leave the ground, the support angle is adjusted by rotating the rotating frame 6, the support length is shortened by adjusting the hydraulic lifting rod 5, and the auxiliary wheel 9 and the moving wheel 10 are rolled together to assist the trolley to move forward, so that the gas cylinder is more stable during transportation and less likely to dump.

[0031] In one embodiment, Figure 5 As shown, the side wall of the fixed cylinder 12 is rotatably connected to the cylinder door 11 through a hinge, and the side wall of the cylinder door 11 away from the hinge is snap-fitted to the side wall of the fixed cylinder 12 through a buckle. The cylinder door 11 is rotated to open, and the gas cylinder is placed on the first buffer block 13, and then the cylinder door 11 is rotated back to its original position and fixed by the buckle to prevent the gas cylinder from falling out during transportation.

[0032] In one embodiment, Figure 5 and Figure 6 As shown, the buffer assembly includes a first buffer block 13, a connecting rod 14, a moving block 15, and a fixed rod 16. The inner bottom wall of the fixed cylinder 12 is provided with four moving block grooves evenly distributed around the circumference. The inner side walls of the four moving block grooves are all slidably connected with the moving blocks 15. The moving blocks 15 and the inner side walls of the moving block grooves are fixedly connected with damping springs. The upper surface of the moving block 15 is rotatably connected with the connecting rod 14 through a pin shaft. The ends of the four connecting rods 14 away from the moving block 15 are jointly rotatably connected with the first buffer block 13 through a pin shaft. When a bumpy road section is encountered during the process, the first buffer block 13 will vibrate up and down, driving the connecting rod 14 to rotate. The connecting rod 14 drives the moving block 15 to reciprocate along the fixed rod 16. The damping spring reduces the energy generated by the vibration, protects the gas cylinder, prevents the gas cylinder from colliding with the inner side wall of the fixed cylinder 12 during transportation, and also reduces the impact force of the gas cylinder when it is bumped.

[0033] In one embodiment, Figure 6 As shown, the inner side walls of the four moving block grooves are all fixedly connected with fixed rods 16, and the moving block 15 is slidably connected with the fixed rods 16. The fixed rods 16 limit the moving block 15.

[0034] In one embodiment, Figure 5 , Figure 7 , Figure 8As shown, the inner side walls of the cylinder door 11 and the fixed cylinder 12 are both provided with second buffer block grooves, the inner side walls of the two second buffer blocks are both slidably connected with second buffer blocks 18, a damping spring is fixedly connected between the second buffer block 18 and the inner side wall of the buffer block groove, the side walls of the two second buffer blocks 18 are both fixedly connected with clamping cylinders 19, the inner side walls of the two clamping cylinders 19 are both penetrated with clamping rods 20 that are slidably connected, a damping spring is fixedly connected between the clamping rods 20 and the inner side wall of the clamping cylinder 19, and a clamping block 17 is fixedly connected to one end of the clamping rod 20 located outside the clamping cylinder 19. When the cylinder door 11 rotates back to its original position, the two clamping blocks 17 clamp the gas cylinder, and the two clamping blocks 17 firmly fix the gas cylinder in the cylinder door 11 through the clamping rod 20 and the damping spring in the clamping cylinder 19, thereby improving the safety of gas cylinder transportation. Example 2

[0035] In one embodiment, Figure 7 As shown, the opposite side walls of the two clamping blocks 17 are both provided with anti-skid rubber pads. The clamping blocks 17 have a better and more stable fixing effect on the gas cylinder.

[0036] In one embodiment, Figure 1 and Figure 2 As shown, reinforcing rods 4 are fixedly connected between the two first connecting rods 3 and the two handle frames 1, thereby improving the supporting strength of the cart.

[0037] The above embodiment discloses an anti-dumping gas cylinder cart. When the gas cylinder cart needs to be pushed, the cart is first stood up, the support angle is adjusted by rotating the handle frame 1, and the support length is increased by adjusting the hydraulic lifting and retracting rod 5 to achieve support for the standing cart.

[0038] The cylinder door 11 is rotated to open, and the gas cylinder is placed on the first buffer block 13, and then the cylinder door 11 is rotated back to its original position and fixed by a buckle to prevent the gas cylinder from falling outside during transportation. When the cylinder door 11 is rotated back to its original position, the two clamping blocks 17 clamp the gas cylinder, and the two clamping blocks 17 firmly fix the gas cylinder in the cylinder door 11 through the clamping rod 20 and the damping spring in the clamping cylinder 19, thereby improving the safety of gas cylinder transportation;

[0039] When encountering a bumpy road section during the process, the first buffer block 13 will vibrate up and down, driving the connecting rod 14 to rotate, and the connecting rod 14 drives the moving block 15 to reciprocate along the fixed rod 16. The damping spring reduces the energy generated by the vibration, protects the gas cylinder, prevents the gas cylinder from colliding with the inner wall of the fixed tube 12 during transportation, and also reduces the impact force of the gas cylinder when it is bumped.

[0040] After the gas cylinder is fixed, the handle frame 1 is pressed down to make the first fixing plate 2 of the bottom support leave the ground, the support angle is adjusted by rotating the rotating frame 6, the support length is shortened by adjusting the hydraulic lifting rod 5, and the auxiliary wheel 9 and the moving wheel 10 are rolled together to assist the trolley to move forward, so that the gas cylinder is more stable during transportation and less likely to tip over.

[0041] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
