[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0032] See also Figure 1-4 The utility model provides a technical solution: a height-adjustable mobile support base, comprising:

[0033] The movable seat 1 has a downwardly opening groove body in which a moving wheel 9 is hingedly connected; in this embodiment, the moving wheel 9 is a cylindrical moving wheel with the same width as the groove body of the movable seat 1;

[0034] A multi-section hinge 2, the end of which is hinged to the movable seat 1;

[0035] A support seat 3, with objects placed on the top surface, and the movable seat 1 and the multi-section hinge 2 are slidably connected in the bottom groove body;

[0036] A plurality of connecting shafts 4 are provided through the movable seat 1, and the ends thereof are inserted into and slidably connected to the adjusting holes 5 of the supporting seat 3, and the adjusting holes 5 are provided to be inclined to the horizontal plane; in this embodiment, the connecting shafts 4 and the movable seat 1 can be connected in an articulated or fixed manner;

[0037] The adjusting wrench 7 has one end hinged to the multi-section hinge 2 and the support seat 3. The hinged position of the adjusting wrench 7, the multi-section hinge 2 and the support seat 3 is arranged along the axis direction of the groove body of the support seat 3. In this embodiment, the hinged position of the adjusting wrench 7 and the multi-section hinge 2 is closer to the movable seat 1, so that when the moving wheel 9 is immersed in the support seat 3, the adjusting wrench 7 is perpendicular or inclined to the support seat 3, and when the moving wheel 9 moves out of the support seat 3, the adjusting wrench 7 is parallel or inclined to the support seat 3 with a reduced slope, such as Figure 2-3 Similarly, the hinge of the adjusting wrench 7 and the supporting seat 3 can be designed to be closer to the movable seat 1, so that the position of the adjusting wrench 7 can be swapped under different moving wheel 9 states for practical use.

[0038] The connecting shaft 4 is provided with limit plates inside and outside the adjusting hole 5 to improve the stability of the movable seat 1 sliding along its axial direction in the supporting seat 3, avoid deviation, and realize efficient transmission in the structure.

[0039] The adjusting hole 5 is provided with a lifting section 51 obliquely for guiding the vertical displacement of the movable seat 1 and the supporting seat 3 .

[0040] The end of the adjustment hole 5 is provided with a stop section 52 for cooperating with the connecting shaft 4 to realize positioning after the position of the movable seat 1 is adjusted.

[0042] A corrugated grip 71 is provided at the outer end of the adjusting wrench 7, so that when the adjusting wrench 7 is rotated manually, the pressure on the hand is reduced, thereby improving the user experience.

[0043] The working principle of a height-adjustable mobile support base of this embodiment includes: when the moving wheel 9 is immersed in the support seat 3, as shown in FIG. Figure 2 When the movable support base needs to be moved, one hand holds the support base 3 or the object placed on it, and the other hand holds the adjusting wrench 7 and rotates it, so that the connecting plate 6 is pulled to drive the movable seat 1 to slide outward along the axis of the support base 3, and the multi-section hinge 2 is folded synchronously to achieve the vertical structural adjustment support, and the connecting shaft 4 slides along the lifting section 52, so that the movable seat 1 connected thereto and the support base 3 are displaced in the vertical direction relative to each other, so that the moving wheel 9 moves out of the support base 3, and the end of the connecting shaft 4 is positioned on the stop section 52 to achieve the positioning of the movable seat 1, and the height of the object can be adjusted, which is convenient for movement. Figure 3 .

[0044] In summary, due to the adoption of the above technical solution, the height-adjustable mobile support base of this embodiment has the following beneficial effects compared with the prior art:

[0045] The support seat and the movable seat in the support base are slidably connected. By rotating the adjustment wrench, the connecting shaft cooperates with the adjustment hole, and the multi-section hinge is used to adjust the guide support of the vertical structure, so that the moving wheel can be immersed in the support seat, the object can be placed, and the moving wheel can be moved out of the support seat to adjust the height of the object and switch the state for easy movement, which is simple to operate.
