[0040] Please refer to the attached Figure 1-Figure 3 , showing a convenient trolley for moving gas cylinders over short distances provided in an embodiment of the present application, including a frame assembly, a wheel assembly and a sleeve-type stabilizing frame.

[0041] The frame assembly is used to tow the gas cylinder. A wheel assembly is arranged at the bottom of the frame assembly, and the whole convenient vehicle can be flexibly moved by relying on the wheel assembly. The upper end of the frame assembly is laterally fixedly connected with a first cross frame 11, and a sleeve-type stabilizing frame is rotatably installed on the first cross frame 11.

[0042] After the gas cylinder is placed on the frame assembly at an angle, the user rotates the sleeve-type stabilizing frame and puts the sleeve-type stabilizing frame on the head end of the gas cylinder, so that the gas cylinder can be placed firmly on the frame assembly to avoid the risk of the gas cylinder sliding sideways when moving the convenient cart, thereby preventing the gas cylinder from slipping.

[0043] The sleeve-type stabilizing frame includes a rotating frame 12 , an upper arc frame 13 , and a lower arc frame 14 .

[0044] The first end of the rotating frame 12 is rotatably connected to the first horizontal frame 11. Two rotating frames 12 are provided. The two rotating frames 12 are distributed in parallel and spaced apart. An upper arc frame 13 and a lower arc frame 14 are rotatably connected between the two rotating frames 12. The opening of the upper arc frame 13 faces downward, and the opening of the lower arc frame 14 faces upward. The upper arc frame 13 is located on the outside of the lower arc frame 14, that is, the lower arc frame 14 is closer to the first horizontal frame 11, and the rotating axes corresponding to the upper arc frame 13 and the lower arc frame 14 are parallel to the first horizontal frame 11.

[0045] Before the gas cylinder is loaded onto the vehicle (the gas cylinder is placed on the vehicle frame assembly), the sleeve-type stabilizing frame is rotated upward as a whole so that it does not affect the loading of the gas cylinder onto the vehicle. After the gas cylinder is loaded onto the vehicle, the lower arc frame 14 is rotated to a position parallel to the rotating frame 12, and the upper arc frame 13 is clamped above the gas cylinder. Then, the lower arc frame 14 is rotated downward so that the lower arc frame 14 is clamped below the gas cylinder. The gas cylinder is restricted by the upper arc frame 13 and the lower arc frame 14, so that the head end of the gas cylinder is not easy to be tilted upward, and the gas cylinder is not easy to tilt left and right.

[0046] In one embodiment, a second horizontal frame 15 is fixedly connected between the two rotating frames 12 , and the second horizontal frame 15 is used to further stabilize the two rotating frames 12 , so that the two rotating frames 12 and the second horizontal frame 15 are an integrated structure.

[0047] In one embodiment, the frame assembly includes: two parallel main frames 8 , a plurality of bottom brackets 9 , a bottom plate 10 and a first cross frame 11 .

[0048] Among them, the bottom support 9 is an arc shape with an opening upward, and the two ends of the bottom support 9 are fixedly connected to the two main frames 8 respectively. Several bottom supports 9 are equidistantly distributed along the length direction of the main frame 8. The bottom plate 10 is fixedly connected to the bottom end of the main frame 8. The top of the main frame 8 forms a handle part for grabbing the handle part to operate the entire convenient vehicle. The first cross frame 11 is fixedly connected between the two main frames 8, and the first cross frame 11 is located above the topmost bottom support 9.

[0049] Two parallel main frames 8 and a plurality of bottom brackets 9 form a semi-cylindrical structure, which corresponds exactly to the side of the gas cylinder, so that the gas cylinder can be placed inside the semi-cylindrical structure, and the bottom plate 10 is used to drag the bottom end of the gas cylinder.

[0050] In one embodiment, a support leg 16 is fixedly connected to the bottom of the main frame 8 and close to the handle, and can be used to place the frame assembly horizontally when the wheel assembly is stored.

[0051] In one embodiment, the bottom bracket 9 is fixedly connected to the bottom plate 10 , which can increase the stability of the connection of the bottom plate 10 .

[0052] In one embodiment, the base 9 includes: a first steel frame 901 , a second steel frame 902 and a rubber pad 903 .

[0053] The first steel bar frame 901 and the second steel bar frame 902 are arranged in parallel and at intervals, and both ends of the first steel bar frame 901 and the second steel bar frame 902 are welded and fixed to two parallel main frames 8. Rubber pads 903 are arranged between the first steel bar frame 901 and the second steel bar frame 902 and on the upper parts of the first steel bar frame 901 and the second steel bar frame 902. For example, the cross-section of the rubber pad 903 is T-shaped, and the vertical part of the rubber pad 903 is stuck between the first steel bar frame 901 and the second steel bar frame 902, and the horizontal part of the rubber pad 903 is located above the first steel bar frame 901 and the second steel bar frame 902.

[0054] The rubber pad 903 is used to protect the outer wall of the gas cylinder to prevent the gas cylinder from being damaged by collision with the first steel frame 901 and the second steel frame 902 .

[0055] In one embodiment, the wheel assembly includes: a triangular bracket 1 , a wheel 2 , a first support rod 3 and a connecting rod 6 .

[0056] The triangular bracket 1 is fixedly connected to the main frame 8. Generally, two groups of triangular brackets 1 are arranged. The two groups of triangular brackets 1 correspond to two parallel main frames 8. The wheel 2 is rotatably installed at the bottom of the triangular bracket 1. The top end of the first support rod 3 is rotatably connected to the main frame 8. The bottom end of the first support rod 3 is fixedly installed with a universal wheel 4 with a braking system. The first support rod 3 is provided with a slide rail 5. The first end of the connecting rod 6 is rotatably connected to the main frame 8. The second end of the connecting rod 6 is connected to the slide rail 5 through a bolt assembly 7. When the bolt assembly 7 is tightened, the connecting rod 6 is fixedly connected to the slide rail 5.

[0057] The bolt assembly 7 is tightened, and the connecting rod 6 is fixedly connected to the slide rail 5 (that is, the connecting rod 6 is fixedly connected to the first support rod 3). The connecting rod 6, the first support rod 3 and the main frame 8 form a stable triangle, which can well support the frame assembly.

[0058] The bolt assembly 7 is loosened, and the bolt part of the bolt assembly 7 can slide inside the slide rail 5. At this time, the connecting rod 6 and the first support rod 3 can be rotated inwards to store the connecting rod 6 and the first support rod 3.
