Description

Technical Field

[0001] This utility model belongs to the field of home appliance accessories, and relates to a mobile stand, and more particularly to a portable mobile stand. Background Technology

[0002] In existing technologies, portable mobile stands have been widely used in the daily movement of household appliances, such as washing machines and furniture boxes. However, most traditional mobile stands suffer from drawbacks such as fixed height, inconvenient adjustment, and insufficient stability. Commonly used roller assemblies are usually installed at the bottom of the stand and cannot be flexibly adjusted in height, resulting in poor adaptability to complex environments such as uneven ground, steps, or slopes, thus limiting their application scenarios. Some stands with height adjustment functions often rely on threaded adjustments, spring clips, or auxiliary tools for operation, which is not only cumbersome and inefficient but also prone to structural instability and accidental displacement during adjustment, posing safety hazards. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a portable mobile stand to solve these issues.

[0004] The purpose of this utility model can be achieved through the following technical solution: a portable mobile support, characterized in that it includes an outer frame, an inner frame that is slidably disposed in the outer frame, and two auxiliary moving components, with a handle connected to one end of the inner frame for easy manual operation; The movable component includes a wheel frame movably connected to the inner frame, rollers mounted on the wheel frame, guide holes located on both sides of the outer frame, and connecting pins passing through the guide holes and connecting the inner frame and the outer frame. The wheel frame is connected to the inner frame via a hinge shaft, and the outer frame is provided with a pin for limiting the relative position of the inner frame and the outer frame. The inner frame is provided with a limiting hole that cooperates with the pin. The pin and the limiting hole can be used to limit the axial movement distance of the inner frame. The guide hole is inclined along the end of the inner frame. The handle moves the inner frame along the axial direction of the outer frame. The central axis of the connecting pin can move axially along the inclined guide hole, thereby realizing the axial height adjustment of the roller assembly.

[0005] In the aforementioned portable mobile support, the guide hole is an oblique elongated hole with an inclination angle between 15° and 45°.

[0006] In the aforementioned portable mobile stand, the connecting pin is a detachable structure, facilitating replacement or maintenance.

[0007] Compared with existing technologies, this portable mobile stand achieves convenient height adjustment through tilting guide holes and hinged wheel frame structure. Combined with pin limit and detachable connecting pin, it combines operability, stability and maintainability, and is suitable for occasions that require frequent movement and height adjustment.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 , Figure 3 As shown, this portable mobile support includes an outer frame 1, an inner frame 2 slidably disposed within the outer frame 1, and two auxiliary moving components. A handle 10 is connected to one end of the inner frame 2 for easy manual operation. The moving components include a wheel frame 3 movably connected to the inner frame 2, rollers 4 mounted on the wheel frame 3, guide holes 5 located on both sides of the outer frame 1, and a connecting pin 6 passing through the guide holes 5 and connecting the inner frame 2 and the outer frame 1. The wheel frame 3 is connected to the inner frame 2 via a hinge shaft 7. The outer frame 1 is provided with a pin 8 for limiting the relative position of the inner frame 2 and the outer frame 1. The inner frame 2 is provided with a limiting hole 9 that cooperates with the pin 8. The pin 8 and the limiting hole 9 can be used to limit the axial movement distance of the inner frame 2. The guide hole 5 is set in an inclined structure along the end of the inner frame 2. The inner frame 2 is moved along the axial direction of the outer frame 1 by the handle 10. The central axis of the connecting pin 6 can move axially along the inclined guide hole 5, thereby realizing the axial height adjustment of the roller 4 assembly.

[0014] The guide hole 5 is an oblique elongated hole with an inclination angle between 15° and 45°. The connecting pin 6 is a detachable structure for easy replacement or maintenance.

[0015] The height-adjustable mechanism of the aforementioned structure can be achieved through a simple push-pull action, requiring no additional tools, significantly improving operational convenience and applicability, and adapting to different ground conditions or handling needs. The cooperative design of the inclined guide hole 5 and the connecting pin 6 enables smooth and reliable height changes; the structure is simple yet highly efficient. The cooperation of the pin 8 and the limiting hole 9 provides stable positioning capability, preventing accidental movement of the bracket and enhancing safety. In addition, the connecting pin 6 adopts a detachable design, facilitating daily maintenance or component replacement and extending the product's service life. The overall structure combines portability, multifunctionality, and a good user experience, making it suitable for various application scenarios requiring frequent movement and height adjustments.

[0016] Working principle When the handle 10 is manually operated to push or pull the frame body axially within the outer frame 1, the connecting pin 6 moves along the guide holes 5 inclined on both sides of the outer frame 1. Since the guide holes 5 are obliquely elongated holes, typically with an inclination angle between 15° and 45°, the movement trajectory of the connecting pin 6 is not horizontal but rather changes obliquely, thereby causing the wheel frame 3, connected to the inner frame 2 via the hinge shaft 7, to rotate. This rotational movement directly changes the ground clearance of the rollers 4 mounted on the wheel frame 3, enabling flexible adjustment of the overall height of the support. Furthermore, the pin 8 on the outer frame 1 can cooperate with the limiting hole 9 on the inner frame 2 to fix the relative position of the inner and outer frames 1, thereby limiting the range of movement and ensuring stability and safety during operation.

[0017] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0018] Although this document uses a considerable amount of technical terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
