DETAILED DESCRIPTION

[0033] The following embodiments and features in the embodiments can be combined with each other under the condition of no conflict.

[0034] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the present application, and only the components related to the present application are shown in the diagrams, rather than being drawn according to the number, shape and size of the components in actual implementation. The shapes, number and proportions of the components in actual implementation can be changed at will, and the layout of the components can be more complex.

[0035] Embodiment 1: Reference Figures 1-5 A dolly chassis capable of stably moving goods, comprising a support frame 10, two support legs 20 and two directional rolling wheels 30 and two steering rolling wheels 40 installed on the support frame 10. The directional rolling wheels 30 and the steering rolling wheels 40 are respectively installed on both sides of the support frame 10, and the support legs 20 are arranged close to one side of the steering rolling wheels 40. The steering rolling wheels 40 are further provided with a conversion structure 50 capable of converting between being pressed against the ground and being lightly floating on the ground. When the steering rolling wheels 40 are lightly floating on the ground, the support legs 20 are in contact with the ground. When the steering rolling wheels 40 are pressed against the ground, the support legs 20 are separated from the ground. In this embodiment, the steering rolling wheels 40 are universal wheels. (The state of the steering rolling wheels 40 lightly floating on the ground means that there may be slight contact with the ground, but almost no force is applied to the ground)

[0036] By providing the conversion structure 50, the conversion between the support legs 20 being in contact with the ground and the steering rolling wheels 40 being in contact with the ground is realized. Therefore, when the goods are to be moved to the support frame 10, the support legs 20 can be brought into contact with the ground to ensure that the dolly is stably parked, thereby facilitating the movement of the goods. When the goods are to be rolled and carried, the steering rolling wheels 40 can be brought into contact with the ground, so that the support legs 20 are separated from the ground, thereby realizing the rolling carrying of the goods.

[0037] To realize the conversion between the support legs 20 being in contact with the ground and the steering rolling wheels 40 being in contact with the ground, the conversion structure 50 is provided as follows:

[0038] The conversion structure 50 includes a connecting piece 51, a linkage plate 52, and a cam handle 53. The connecting piece 51 is connected with the support frame 10. One end of the linkage plate 52 is flexibly hinged with the connecting piece 51 (here, the flexible hinge means that the linkage plate is easily rotated under slight external force), and the other end is connected with the directional rolling wheel 40. The cam handle 53 is hinged with the connecting piece 51 and placed on the upper end of the linkage plate 52. When the cam handle 53 is turned downward and tightly presses on the upper end of the linkage plate 52, the directional rolling wheel 40 is tightly pressed on the ground. When the cam handle 53 is turned upward and releases the linkage plate 52, the directional rolling wheel 40 is lightly floated on the ground. The cam handle 53 includes a cam part 531 and a handle part 532 integrally formed with the cam part 531. The cam part 531 is placed on the upper end of the linkage plate 52, and it can tightly press the cam part 531 on the linkage plate 52 or release the linkage plate 52 by rotating the handle part 532.

[0039] Since the linkage plate 52 is flexibly hinged with the connecting piece 51, when the cam part 531 releases the linkage plate 52, the reaction force of the ground on the directional rolling wheel 40 makes the linkage plate 52 turn upward, so that the directional rolling wheel 40 is again lightly floated on the ground, and the supporting leg 20 contacts the ground. Therefore, the cam handle 53 can press or release the linkage plate 52, so that the directional rolling wheel 40 is tightly pressed on the ground or lightly floated on the ground, thereby realizing the conversion of the contact between the supporting leg 20 and the ground and the contact between the directional rolling wheel 40 and the ground.

[0040] In order to adapt the supporting leg 20 to wheels of different sizes, a height adjustment structure 70 is arranged to adjust the distance between the supporting leg 20 and the ground, so as to ensure the height difference between the supporting leg 20 and the directional rolling wheel 30 or the directional rolling wheel 40. The support frame 10 is connected with the supporting leg 20 through a connecting plate 60. The height adjustment structure 70 is arranged between the connecting plate 60 and the supporting leg 20 to adjust the distance between them. The height adjustment structure 70 includes a threaded column 71 arranged on the upper end of the supporting leg 20 and a connecting through hole 72 arranged on the connecting plate 60. The threaded column 71 is screwed with the inner thread arranged on the inner wall of the connecting through hole 72, so as to adjust the height of the supporting leg 20. Alternatively, the threaded column 71 passes through the connecting through hole 72, and two nuts are respectively screwed on the threaded column 71 on both sides of the connecting through hole 72, so as to adjust the height of the supporting leg 20. In this embodiment, the second method is adopted.

[0041] To improve the adaptability of the support frame 10 to different cargo sizes and transport channels, the support frame 10 is configured to have adjustable length and width. The support frame 10 is rectangular and includes four sets of corner components 11 located at the four corners of the support frame 10, and four sets of length adjustment components 12 respectively disposed between two adjacent corner components 11. Two sets of parallel length adjustment components 12 are used to adjust the length in the straight line direction of the two directional rollers 40, and the other two sets of parallel length adjustment components 12 are used to adjust the length in the straight line direction of the directional roller 30 and the directional roller 40.

[0042] The end corner assembly 11 includes two vertically welded end plates 111. The length adjustment assembly 12 includes one or more adjustment plates 121 and a plurality of adjustment connection holes 122 disposed on the two end plates 111 and the adjustment plates 121. In this embodiment, two adjustment plates 121 are provided with different lengths. The adjustment connection holes 122 cooperate with bolts and nuts (bolts and nuts are shown in the figure but not labeled) to connect and lock the adjustment plates 121 and the end plates 111 or the two adjustment plates 121. The adjustment connection holes 122 are arranged at equal intervals, and the hole diameters can be the same or different, as long as the adjustment connection holes 122 of different plates can correspond and allow bolts and nuts to pass through and cooperate with them.

[0043] To enable the support frame 10 to support the installation of goods, each corner component 11 is provided with a support mounting plate 13 at its corner for placing mounting plates (not shown in the figure) to support the goods to be moved. The support mounting plate 13 is provided with mounting connection holes 131, which cooperate with bolts and nuts (shown in the figure but not labeled) to connect and lock the mounting plate to the support mounting plate 13.

[0044] To enable the directional rolling wheel 30 to roll relative to the support frame 10 while protecting the directional rolling wheel 30 and reducing the possibility of the directional rolling wheel 30 affecting the rolling process, the directional rolling wheel 30 is rotatably connected to the support frame 10 through a protective frame 80, and the directional rolling wheel 30 is protected between the protective frame 80 and the support frame 10.

[0045] In the above setup, gaskets are installed at the parts involving pin hole connection (the gaskets are in...). Figure 4 (Examples are shown but not labeled), such as the rolling connection of the directional roller 30 and the adjusting roller 40, and the hinge connection between the cam handle 53, the linkage plate 52 and the connector 51.

[0046] This utility model also provides a transport vehicle (not shown in the figure), which includes the aforementioned transport vehicle chassis. Of course, the transport vehicle also includes necessary components such as a steering mechanism to ensure the smooth completion of the entire operation process.

[0047] The working process of the embodiment is as follows:

[0048] When the goods need to be moved, the cam handle 53 is turned upward, the cam part 531 does not exert pressure on the linkage plate 52, the steering roller 40 is ensured to be light on the ground, the supporting leg 20 contacts the ground, at this time the supporting is realized by the supporting leg 20 and the directional roller 30, the trolley chassis is not easy to roll, the parking is stable, and the goods are convenient to move; when the goods are moved and need to be rolled, the cam handle 53 is turned downward, the cam part 531 is pressed downward to the end of the linkage plate 52 where the steering roller 40 is located, the steering roller 40 contacts the ground, and the supporting leg 20 is lifted to be separated from the ground, at this time the supporting is realized by the steering roller 40 and the directional roller 30, and the rolling moving can be realized.

[0049] The above description is only one specific example of the utility model, and does not constitute any limitation on the utility model. Obviously, for those skilled in the art, after understanding the content and principle of the utility model, various modifications and changes in form and details can be made without departing from the principle and structure of the utility model, but these modifications and changes based on the idea of the utility model are still within the protection scope of the claims of the utility model.
