[0004] To achieve the above objectives, this utility model provides a base structure including a telescopic assembly. The telescopic assembly includes a first outer tube, a first inner tube, a first driving member, and a first roller. Both the first outer tube and the first inner tube are used for load-bearing. The rear end of the first inner tube is slidably installed in the first outer tube, and the front end of the first driving member is installed in the first inner tube. The rear end of the first driving member extends out of the first inner tube and is installed in the first outer tube to drive the first inner tube to slide relative to the first outer tube. The first roller is installed at the front end of the first outer tube and can abut against the lower part of the first inner tube, so that the first roller can rotate relative to the first inner tube and support the first inner tube.

[0005] In some embodiments, the first roller includes a first wheel, a first shaft, and a first mounting base. The first wheel is rotatably connected to the first mounting base via the first shaft. The first mounting base is fixedly connected to the front end of the first outer tube. The outer peripheral wall of the first wheel abuts against the lower part of the first inner tube.

[0006] In some embodiments, the first mounting base includes a mounting portion and an extension portion. The mounting portion is mounted on both sides of the front end of the first outer tube, and the extension portion is disposed at the front end of the mounting portion and extends downward. The first wheel is rotatably connected to the extension portion via the first rotating shaft.

[0007] In some embodiments, mounting plates extending forward are provided on both sides of the front end of the first outer tube, the first mounting seat is mounted on the mounting plate, and the connection position between the first mounting seat and the mounting plate is the mounting area, the mounting area is at least partially located on the front side of the first wheel, or the mounting area is at least partially located on the same axis as the first wheel.

[0008] In some embodiments, a baffle is connected to the lower front end between the mounting plates located on both sides of the first outer tube. The baffle is spaced apart from the front end of the first outer tube, and the first wheel is arranged between the baffle and the front end of the first outer tube.

[0009] In some embodiments, a plurality of second rollers are included, the plurality of second rollers being mounted at least at the upper and lower portions of the rear end of the first inner tube, and the rear end of the first inner tube being slidably mounted in the first outer tube via the second rollers.

[0010] In some embodiments, the telescopic assembly includes a first connector and a second connector, and the telescopic assembly is provided in multiple sets. The first connector is installed at the rear end of the first outer tube of two adjacent sets of the telescopic assembly; the two ends of the second connector are installed between the first inner tube of two adjacent sets of the telescopic assembly.

[0011] In some embodiments, the first connector includes a second outer tube and two second inner tubes, with one end of each of the two second inner tubes slidably mounted on both ends of the second outer tube.

[0012] In some embodiments, the first connector includes a plurality of third rollers, and the upper and lower parts of one end of the second inner tube are slidably mounted in the second outer tube via the third rollers.

[0013] In some embodiments, the first connector includes two second driving members, which are respectively arranged in a one-to-one correspondence with two second inner tubes. One end of the second driving member is installed in the second inner tube, and the other end of the second driving member extends out of the second inner tube and is installed in the second outer tube. The second driving member is used to drive the second inner tube to slide in the second outer tube.

[0014] This utility model provides a base structure, which has the following advantages compared with the prior art:

[0015] The telescopic assembly includes a first outer tube, a first inner tube, a first driving member, and a first roller. Both the first outer tube and the first inner tube are used for load-bearing. The rear end of the first inner tube is slidably installed within the first outer tube, and the front end of the first driving member is installed within the first inner tube. The rear end of the first driving member extends out of the first inner tube and is installed within the first outer tube to drive the first inner tube to slide relative to the first outer tube. The first roller is installed at the front end of the first outer tube and can abut against the lower part of the first inner tube, allowing the first roller to rotate relative to the first inner tube and support it. Thus, the first driving member can drive the first outer tube and the first inner tube to move relative to each other, achieving the telescopic function. Since the upper parts of the first outer tube and the upper parts of the first inner tube are used for load-bearing, the first inner tube is compressed downwards during telescopic movement. The first roller abuts against the lower part of the first inner tube, providing support during movement and ensuring structural stability, making the first inner tube less prone to deformation.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] It should be understood that in the description of this application, the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.

[0024] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figures 1-5 As shown, the base structure of this utility model embodiment includes a telescopic component 1. The telescopic component 1 includes a first outer tube 11, a first inner tube 12, a first driving member 13, and a first roller 14. Both the first outer tube 11 and the first inner tube 12 are used for load bearing. The rear end of the first inner tube 12 is slidably installed in the first outer tube 11. The front end of the first driving member 13 is installed in the first inner tube 12. The rear end of the first driving member 13 extends out of the first inner tube 12 and is installed in the first outer tube 11 to drive the first inner tube 12 to slide relative to the first outer tube 11. The first roller 14 is installed at the front end of the first outer tube 11, and the first roller 14 can abut against the lower part of the first inner tube 12, so that the first roller 14 can rotate relative to the first inner tube 12 and support the first inner tube 12. Thus, the first inner tube 12 is driven to slide in the first outer tube 11 by the first driving member 13. At this time, the first roller 14 abuts against the lower part of the first inner tube 12. The first roller 14 supports the first inner tube 12, ensuring structural stability and making the first inner tube 12 less prone to deformation.

[0026] When the base structure is used as a load-bearing structure in a mobile building, the first outer tube 11 and the first inner tube 12 of the telescopic component 1 are prone to deformation under the action of gravity load. In particular, the part of the first inner tube 12 that extends out of the first outer tube 11 is subjected to downward pressure, which easily leads to stress concentration and downward bending deformation. As a result, the first outer tube 11 and the first inner tube 12 cannot be unfolded relative to each other. Therefore, the use of the first roller 14 in this embodiment is necessary to ensure smooth relative unfolding between the first outer tube 11 and the first inner tube 12. Especially when the first inner tube 12 and the first outer tube 11 are unfolded, the first roller 14 is located at the junction of the first inner tube 12 and the first outer tube 11, which can enhance the structural strength of the junction of the first inner tube 12 and the first outer tube 11, and effectively support the bottom of the first inner tube 12, making the first inner tube 12 less prone to deformation at the junction.

[0027] Based on the above structural configuration, the first driving component 13 can drive the first outer tube 11 and the first inner tube 12 to move relative to each other, thereby achieving the telescopic function. The first roller 14 abuts against the lower part of the first inner tube 12. During the movement, the first inner tube 12 can play a supporting role through the first roller 14, ensuring structural stability and making the first inner tube 12 less prone to deformation.

[0028] like Figure 2 As shown, in some embodiments, the first roller 14 includes a first wheel 141, a first shaft 142, and a first mounting base 143. The first wheel 141 is rotatably connected to the first mounting base 143 via the first shaft 142. The first mounting base 143 is mounted on the front end of the first outer tube 11, and the outer peripheral wall of the first wheel 141 abuts against the lower part of the first inner tube 12. When the first inner tube 12 slides within the first outer tube 11, the outer peripheral wall of the first wheel 141 abuts against the lower part of the first inner tube 12. At this time, the rotation of the first wheel 141 within the first mounting base 143 supports the sliding first inner tube 12, making it less prone to deformation.

[0029] like Figure 3 As shown, the first mounting base 143 includes a mounting portion 1431 and an extension portion 1432. The mounting portion 1431 is mounted on both sides of the front end of the first outer tube 11, and the extension portion 1432 is located at the front end of the mounting portion 1431 and extends downward. The first wheel 141 is rotatably connected to the extension portion 1432 via the first rotating shaft 142. Thus, the mounting portion 1431 allows the first wheel 141 to extend out of the first outer tube 11, and the extension portion 1432 provides mounting space for the first wheel 141, enabling the first wheel 141 to effectively contact the first inner tube 12, thereby supporting the first inner tube 12 and preventing it from deforming.

[0030] like Figure 3As shown, mounting plates 111 are provided on both sides of the front end of the first outer tube 11. The first mounting seat 143 is mounted on the mounting plate 111, and the connection position between the first mounting seat 143 and the mounting plate 111 is the mounting area. The mounting area is at least partially located on the front side of the first wheel 141, or at least partially located on the same axis as the first wheel 141. This makes the mounting structure stable.

[0031] like Figure 3 As shown, a baffle 112 is connected to the lower front end of the mounting plates 111 located on both sides of the first outer tube 11. The baffle 112 is spaced apart from the front end of the first outer tube 11, and the first wheel 141 is arranged between the baffle 112 and the front end of the first outer tube 11. In this way, the baffle 112 can improve the structural strength between the two mounting plates 111 and will not affect the sliding of the first inner tube 12, so that the mounting structure of the first outer tube 11 and the first wheel 141 is stable.

[0032] like Figure 1 As shown, the base structure includes a first connector 2 and a second connector, and the telescopic assembly 1 has multiple sets. The first connector 2 is installed at the rear end of the first outer tube 11 of two adjacent sets of telescopic assemblies 1. The two ends of the second connector 3 are installed between the first inner tube 12 of two adjacent sets of telescopic assemblies 1. Specifically, the first connector 2 and the second connector 3 are fixed by bolts or welding.

[0033] like Figure 1 As shown, in some embodiments, the first connector 2 is perpendicular to the first outer tube 11, and the second connector 3 is perpendicular to the first inner tube 12. This ensures a stable and reliable installation structure.

[0034] like Figure 1 and 4 As shown, in some embodiments, the first connector 2 includes a second outer tube 21 and two second inner tubes 22, with one end of each of the two inner tubes 22 slidably mounted on both ends of the second outer tube 21. This gives the first connector 2 a telescopic function.

[0035] like Figure 4 As shown, in some embodiments, the first connector 2 includes a plurality of third rollers 23, and the upper and lower parts of one end of the second inner tube 22 are slidably mounted in the second outer tube 21 via the third rollers 23. In this way, the second inner tube 22 slides smoothly in the second outer tube 21.

[0036] like Figure 5As shown, in some embodiments, the third roller 23 includes a third wheel 231, a third shaft 232, and a third mounting base 233. The third wheel 231 is rotatably connected to the third mounting base 233 via the third shaft 232. The third mounting base 233 is mounted on one end of the second inner tube 22, and the outer peripheral wall of the third wheel 231 abuts against the inner wall of the second outer tube 21. When the second inner tube 22 slides in the second outer tube 21, the outer peripheral wall of the third wheel 231 abuts against the inner wall of the second outer tube 21. At this time, the rotation of the third wheel 231 in the third mounting base 233 allows the second inner tube 22 to slide smoothly within the second outer tube 21.

[0037] like Figure 5 As shown, in some embodiments, the first connector 2 includes two second driving members 24, which are correspondingly arranged with two second inner tubes 22. One end of each second driving member 24 is installed in the second inner tube 22, and the other end extends out of the second inner tube 22 and is installed in the second outer tube 21. The second driving member 24 is used to drive the second inner tube 22 to slide within the second outer tube 21. Thus, the second inner tube 22 automatically slides within the second outer tube 21 through the second driving member 24.

[0038] like Figure 1 and 5 As shown, in some embodiments, the first connector 2 includes two connecting plates 25, which are installed one-to-one on the other end of the second inner tube 22. The connecting plates 25 are used to connect with other components of the mobile building.

[0039] In some embodiments, the first outer tube 11, the first inner tube 12, the second outer tube 21, and the second inner tube 22 are all made of square tubes. In this way, when the first inner tube 12 slides inside the first outer tube 11, it will not rotate about the axis of the first outer tube 11, and when the second inner tube 22 slides inside the second outer tube 21, it will not rotate about the axis of the second outer tube 21.

[0040] In some embodiments, the base structure includes a plurality of second rollers 15, which are mounted on the upper and lower parts of the rear end of the first inner tube 12. The rear end of the first inner tube 12 is slidably mounted in the first outer tube 11 via the second rollers 15. This allows the first inner tube 12 to slide smoothly within the first outer tube 11.

[0041] like Figure 4As shown, in some embodiments, the second roller 15 includes a second wheel 151, a second shaft 152, and a second mounting base 153. The second wheel 151 is rotatably connected to the second mounting base 153 via the second shaft 152. The second mounting base 153 is mounted on the rear end of the first inner tube 12, and the outer peripheral wall of the second wheel 151 abuts against the inner wall of the first outer tube 11. When the first inner tube 12 slides within the first outer tube 11, the outer peripheral wall of the second wheel 151 abuts against the inner wall of the first outer tube 11. At this time, the rotation of the second wheel 151 within the second mounting base 153 allows the first inner tube 12 to slide smoothly within the first outer tube 11.

[0042] It should be noted that the first driving component 13 and the second driving component 24 can be hydraulic rods, pneumatic rods or electric push rods.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
