[0004] However, the technical solution of this patent cannot automatically lock the protective cover when it is closed, cannot quickly clamp the gas cylinder, and cannot clamp gas cylinders of multiple sizes.

[0005] Therefore, the technical personnel in this field provide a structure of a gas cylinder trolley to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a structure of a gas cylinder trolley to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A structure of a gas cylinder trolley includes a bottom plate. A vehicle frame is fixedly installed on the upper side of the bottom plate. A protective device is arranged on the front side of the vehicle frame. A multi-size fixing device is arranged on the upper part of the rear side of the vehicle frame. A plurality of wheels are rotatably connected to the lower part of the rear side of the vehicle frame. A vehicle handle is fixedly installed on the upper side of the vehicle frame;

[0009] Furthermore, the multi-size fixing device includes a clamping mechanism and an adjusting mechanism. The two clamping mechanisms are symmetrically installed on the left and right sides of the vehicle frame, and the adjusting mechanism is installed on the clamping mechanism;

[0010] Further, the clamping mechanism includes: a vertical bracket, a rotating rod, and an auxiliary component. The vertical bracket is fixedly installed on the vehicle frame. The rotating rod is rotatably connected to the vertical bracket through a rotating shaft. The auxiliary component is installed on the rotating rod.

[0011] Further, the auxiliary component includes: a fixed roller and a rubber roller. The fixed roller is rotatably connected to the rear side of the rotating rod through a rotating shaft. The rubber roller is rotatably connected to the front side of the rotating rod through a rotating shaft.

[0012] Further, the adjusting mechanism includes: a special-shaped bracket, a sliding trapezoidal block, a rubber buffer block, and a screw. The special-shaped bracket is fixedly installed on the vehicle frame. The sliding trapezoidal block is slidably connected to the special-shaped bracket through a dovetail groove and a dovetail slider. The rubber buffer block is fixedly installed on the front side of the sliding trapezoidal block. The screw is rotatably connected to the rear side of the special-shaped bracket. The front side of the screw is threadedly connected to the sliding trapezoidal block.

[0013] Further, the protection device includes: a protection component and a locking component. The protection component is installed on the front side of the vehicle frame. The locking component is installed on the protection component.

[0014] Further, the protection component includes a protective cover. The protective cover is hinged to the front side of the vehicle frame through a hinge.

[0015] Further, the locking component includes: a housing, a rotating block, and an insertion rod. The housing is fixedly installed on the left side of the vehicle frame. The rotating block is rotatably connected inside the housing. A torsion spring is arranged on the rotating shaft of the rotating block. One end of the torsion spring is fixedly connected to the housing, and the other end of the torsion spring is fixedly connected to the rotating block. The insertion rod is fixedly installed on the left side of the protective cover. Protrusions are arranged on the right side wall of the rotating block and the left side wall of the insertion rod.

[0016] Compared with the prior art, the beneficial effect of the present utility model is: for the structure of a gas cylinder trolley, by pressing the rotating block, the rotating block rotates. The rotation of the rotating block causes the protrusion on the right side wall of the rotating block to leave the protrusion on the left side wall of the insertion rod, opening the protective cover. The rotation of the protective cover drives the insertion rod to rotate, causing the insertion rod to leave the rotating block. At this time, the gas cylinder is placed inside the vehicle frame, and the protective cover is closed. The closing of the protective cover causes the insertion rod to insert into the housing, and the protrusion on the left side wall of the insertion rod closely adheres to the protrusion on the right side wall of the rotating block. The torsion spring restricts the rotation of the rotating block, locking the protective cover, which is beneficial to automatically locking the protective cover when the protective cover is closed.

[0017] The rotation of the screw drives the sliding trapezoidal block to move. The movement of the sliding trapezoidal block causes the fixed roller at the rear side of the rotating rod to move, which makes the rotating rod rotate. The rotation of the rotating rod makes the rubber roller at the front side of the rotating rod closely adhere to the outer wall of the gas cylinder, clamping the gas cylinder. By adjusting the screw, the clamping force and clamping range can be adjusted, which is beneficial for clamping gas cylinders of different sizes and realizing the rapid clamping of gas cylinders at the same time. The utility model can automatically lock the protective cover when the protective cover is closed, can quickly clamp the gas cylinder, and can clamp and fix gas cylinders of multiple sizes.
