Description

Technical Field

[0001] This utility model relates to the field of trolley structure technology, and in particular to a gas cylinder transfer trolley structure. Background Technology

[0002] Gas cylinders are widely used in industrial production and daily life. However, the transfer and transportation of gas cylinders has always been a thorny problem. Traditional trolley structures are often simply designed and do not securely fix gas cylinders. During the transfer process, gas cylinders are easily damaged due to shaking or collisions, which may even cause safety accidents. Moreover, traditional trolleys are not very adaptable to different sizes of gas cylinders and require multiple types of trolleys to meet the needs, which increases the cost of use and management difficulty. Therefore, a gas cylinder transfer trolley structure is needed. Chinese patent provides a structure for a gas cylinder handcart, publication number CN222921578U, including a base plate, a frame fixedly mounted on the upper side of the base plate, a protective device on the front side of the frame, a multi-sized fixing device on the upper rear side of the frame, multiple wheels rotatably connected to the lower rear side of the frame, and a handlebar fixedly mounted on the upper side of the frame; the multi-sized fixing device includes a clamping mechanism and an adjusting mechanism, two clamping mechanisms are symmetrically mounted on the left and right sides of the frame, and the adjusting mechanism is mounted on the clamping mechanism; the clamping mechanism includes a vertical support, a rotating rod, and an auxiliary component, the vertical support is fixedly mounted on the frame, the rotating rod is rotatably connected to the vertical support via a rotating shaft, and the auxiliary component is mounted on the rotating rod.

[0003] The aforementioned trolley structure can automatically lock the protective cover when it is closed, and can quickly clamp the gas cylinder. However, while the multi-size fixing device of the trolley structure can accommodate gas cylinders of different sizes, the operation of the adjustment mechanism is relatively complicated. In actual gas cylinder transfer work, operators may need to spend a lot of time adjusting the fixing device to adapt to different gas cylinders, which reduces work efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a gas cylinder transfer trolley structure that can effectively solve the technical problem in the background art where, although the multi-size fixing device can handle gas cylinders of different specifications, the operation of the adjustment mechanism is relatively complicated. In actual gas cylinder transfer work, operators may need to spend a lot of time adjusting the fixing device to adapt to different gas cylinders, which reduces work efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A gas cylinder transfer trolley structure includes two frames. Universal wheels are fixedly installed on one outer wall of each frame. A telescopic rod is rotatably connected to the adjacent surfaces of the two frames. Wheels are fixedly installed at both ends of the telescopic rod. Handrails are fixedly installed at one end of each frame. Three first connecting rings are fixedly installed on the outer wall of the left-side frame, and three second connecting rings are fixedly installed on the outer wall of the right-side frame.

[0006] As a further embodiment of this utility model, a sliding block is fixedly installed on the outer wall of each of the three first connecting rings, and the outer wall of the sliding block is slidably connected to the second connecting ring.

[0007] As a further embodiment of this utility model, a limiting block is fixedly installed on one side of the outer wall of each of the three sliding blocks, and the limiting block is located on one side of the second connecting ring.

[0008] As a further embodiment of this utility model, a placement frame is fixedly installed at the bottom of each of the two vehicle frames, and five support blocks are fixedly installed on the outer wall of each of the two placement frames, with the support blocks interleaved with each other.

[0009] As a further embodiment of this utility model, a first connecting frame is fixedly installed on the outer wall of the frame on the left side, and a second connecting frame is fixedly installed on the outer wall of the frame on the right side.

[0010] As a further embodiment of this utility model, connecting blocks are fixedly installed on the outer walls of both the first connecting frame and the second connecting frame, and the two connecting blocks correspond to each other.

[0011] As a further embodiment of this utility model, the outer walls of the two connecting blocks are provided with screws, and the outer walls of the screws are threadedly connected to the outer walls of the two connecting blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1) This gas cylinder transfer trolley structure allows the gas cylinder to be placed in the placement frame first, where the support block provides stable support and prevents the gas cylinder from shaking on the trolley. Then, according to actual needs, the position of the sliding block can be flexibly adjusted through the first and second connecting rings, thereby driving the limit block to move, so that the first and second connecting rings can better fit the gas cylinder, further stabilizing it. During the movement of the trolley, the first and second connecting frames, through the cooperation of the connecting block and the screw, ensure that the two sides of the frame are tightly connected, ensuring the stability of the entire trolley structure and preventing the frame from separating or shaking during movement. The adjustability of the first and second connecting rings and the sliding block can also be used to quickly adjust to accommodate gas cylinders of different sizes, improving the versatility and practicality of the trolley.

[0013] 2) The structure of this gas cylinder transfer trolley is very convenient to disassemble or assemble when needed through the threaded connection, which can greatly save time and labor costs. In daily use, if a part of the trolley is damaged, the operator can quickly disassemble the damaged part by simple rotation and replace it with a new part without complicated tools and cumbersome procedures. Moreover, the trolley can also be disassembled when transporting it, reducing the space occupied and making it convenient to handle and store. Attached Figure Description
