[0002] A transport cart is a very common means of transportation in our lives. It is mainly used to carry heavy objects. In order to facilitate the transportation of goods of different sizes, the transport cart is usually set to a retractable and foldable state.

[0003] Patent application number US10053129B1 discloses a transport vehicle, including two side frames and a telescopic rod structure in the middle. The distance between the two side frames is adjusted by stretching the telescopic rod. However, this telescopic structure can only be extended to one side, and the operation is not flexible enough, which greatly affects the transport efficiency. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] The technical problem to be solved by the present invention is that the existing transport vehicle can only achieve single-side stretching and folding, and the operation is not flexible enough, which affects the transport efficiency.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 4 As shown, a transport vehicle comprises a supporting pallet 1 and a moving frame 2 located on both sides of the supporting pallet 1, the moving frame 2 is fixedly connected to a protective side plate 15 on the side away from the supporting pallet 1, the bottom surface of the moving frame 2 is provided with four moving wheels 7 arranged along the length direction, the bottom surface of the moving frame 2 is fixedly connected with a fixing sleeve 4 on both sides, the fixing sleeve 4 is inserted with an adjusting cross bar 3, the fixing sleeve 4 is provided with a fixing mechanism between the adjusting cross bars 3, the fixing mechanism comprises a second slot located at the other end of the adjusting cross bar 3 and arranged symmetrically with the first slot, a fixing column 11 is slidably inserted in the second slot, and the bottom surface of the fixing sleeve 4 A fixing socket 14 is provided to cooperate with the fixing column 11, and the adjusting cross bar 3 can be conveniently installed and disassembled through the fixing mechanism. When the adjusting cross bar 3 needs to be disassembled, the fixing column 11 is pressed inwardly so that the fixing column 11 extends from the fixing socket 14 into the second slot to squeeze the spring to cause compression deformation, and the adjusting cross bar 3 is pulled outward to pull the adjusting cross bar 3 out of the fixing sleeve 4. The bottom surface of the supporting plate 1 is fixedly connected with a first movable sleeve 5 to cooperate with the adjusting cross bar 3, and the bottom surface of the movable frame 2 is located on one side of the fixing sleeve 4 and is fixedly connected with a second movable sleeve 6. The adjusting cross bars 3 on both sides first pass through the first movable sleeve 5 and then are inserted into the second movable sleeve 6.

[0024] The adjusting cross bar 3 is provided with a limiting mechanism, and the limiting mechanism includes a first slot located at one end of the adjusting cross bar 3, and a limiting column 8 is slidably inserted in the first slot. A ball 9 is fixedly connected to the upper end of the limiting column 8, and a return spring 10 is fixedly connected to the bottom surface of the limiting column 8. The bottom surfaces of the mobile frame 2 and the supporting pallet 1 are respectively provided with a sliding groove 16 connected to the first movable sleeve 5 and the second movable sleeve 6 and coordinated with the limiting column 8, and the mobile frame 2 and the supporting pallet 1 are respectively provided with a positioning hole 13 connected to the first movable sleeve 5 and the second movable sleeve 6.

[0025] In specific use, when it is necessary to adjust the distance between the two sides of the moving frame 2, as shown in FIG. Figure 5As shown, the moving frames 2 on both sides are pulled away from each other, and the two moving frames 2 pull the corresponding adjusting cross bars 3 to slide along the inner wall of the second movable sleeve 6. When the ball 9 contacts one end of the slide groove 16, the limiting column 8 is pushed to slide into the first slot under the extrusion of the slide groove 16, and the return spring 10 is compressed and deformed, so that the upper end of the ball 9 is pressed against the inner wall of the slide groove 16 to slide. When the limiting column 8 slides into the positioning hole 13, the limiting column 8 is pushed to extend upward under the restoring elastic force of the return spring 10, so that the limiting column 8 is stuck in the positioning hole 13. At this time, if there is no external force, it is difficult for the moving frames 2 on both sides to extend again. When it is necessary to extend again, the moving frames 2 on both sides are pulled hard again, and the ball 9 is squeezed to drive the limiting column 8 to extend again. The adjusting cross bars 3 are inserted into the first slot so that the adjusting cross bars 3 extend from the second movable sleeves 6 on both sides. The adjusting cross bars 3 on both sides can continue to stretch left and right along the first movable sleeves 5 for adjustment. The goods are placed on the middle supporting drag plate, and the mobile frames 2 on both sides are pushed close to each other so that the protective side plates 15 on both sides are close to the two sides of the goods, so that the goods can be clamped and fixed. Since the inner diameters of the fixed sleeve 4, the first movable sleeve 5, and the second movable sleeve 6 are slightly larger than the adjusting cross bar 3, there is a certain amount of movable space between the outer wall of the adjusting cross bar 3 and the inner walls of the fixed sleeve 4, the first movable sleeve 5, and the second movable sleeve 6. When encountering a bumpy road surface, it can be buffered to prevent the connection part from breaking during the bump, thereby greatly improving the stability of transporting goods.

[0026] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.
