Description

An adjustable universal support Technical Field

[0001] This invention relates to the field of support tool technology, specifically to an adjustable universal support. Background Technology

[0002] Universal support, professionally known as "adjustable support base", is now widely referred to as "universal support". It is mainly used for ground support and stilts. It is specially designed for projects such as garden landscape, mirror water features, roof gardens, wooden platform construction, lattice floor stilts, squares, dry fountains, interior decoration, balcony decoration, and prefabricated houses. Universal support products are mainly simple and practical, and the system height is adjustable.

[0003] Currently, when assembling multiple square stone or wooden slabs into a suspended base, supports need to be installed at the bottom of the slabs for support. In use, firstly, to determine the placement of the supports, determine the starting position, draw a horizontal line, and create a grid. Secondly, temporarily place the supports on the grid, place the stone or wooden slabs on the supports, and place a level on the stone or slab. Observe the level and adjust the supports one by one to adjust the level of the stone or slab. Then, after the stone and slab are placed, repeat the slope adjustment, using the level while placing other stone or slabs. Generally, a single slab requires at least four supports to support each corner or side to ensure its stability.

[0004] Most existing universal supports require assembly and disassembly to adjust their maximum and minimum heights, which is time-consuming, inconvenient, and impractical. Furthermore, they waste packing space during transportation, significantly increasing logistics and packaging costs.

[0005] Meanwhile, when adjusting the height of the existing universal support, the base and the support may rotate and fall off. In more serious cases, the threads may almost fall off (with only 1-2 threads remaining), but this is not visible on the outside. As a result, the load-bearing capacity of the entire system decreases without being detected in time, which can easily lead to accidents.

[0006] Therefore, an adjustable universal support is proposed to address the current shortcomings. Technical solutions

[0007] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide an adjustable universal support.

[0008] To solve the above-mentioned technical problems, the present invention provides an adjustable universal support, comprising a top base, an adjustment part, a heightening part, and a bottom base;

[0009] A partition plate is snapped onto the top base. The lower end of the top base is located inside the adjustment part and is threadedly connected to the adjustment part. The lower end of the adjustment part is located inside the heightening member and is threadedly connected to the heightening member. The lower end of the heightening member is threadedly connected to the bottom base.

[0010] The adjusting part includes a plurality of threaded parts of gradually varying sizes that are sequentially sleeved together. Any two adjacent threaded parts are threadedly connected, and the adjusting part is extendable and retractable along the axial direction of the threaded parts.

[0011] The upper threaded component of the adjacent threaded components is provided with a buckle at its bottom end, and the lower threaded component is provided with a straight groove that engages with the buckle.

[0012] As an improvement, the threaded part at the lower end of the adjustment section is screwed counterclockwise to the heightening part, and the heightening part is screwed counterclockwise to the base.

[0013] As an improvement, the bottom end of the top base is provided with a snap-fit ​​device that engages with the straight groove.

[0014] As an improvement, the upper part of the heightening component is provided with a cross-shaped support.

[0015] As an improvement, the top base has a petal-shaped structure, and a grid ring is provided on the outer side of the top base.

[0016] As an improvement, a tightening part is provided on the upper outer side of the threaded part located at the lower end of the adjustment part. Beneficial effects

[0017] The advantages of this invention compared to the prior art are:

[0018] The height of the support can be adjusted by rotating between the top base and the adjustment part, and between the threaded parts in the adjustment part. At the same time, by retracting the support, the space occupied can be reduced, saving packing space and greatly reducing logistics and packaging costs.

[0019] By tightening the threaded part at the lower end of the adjustment section and the extension part, and the lower end of the extension part and the base counterclockwise, the stability of the connection of the support can be ensured during the deployment process.

[0020] This support has a simple structure and is easy to use. While ensuring its flexibility, it also ensures the stability of its overall structure. At the same time, its retractable form greatly reduces packaging and transportation costs, making it highly valuable for promotion and use. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the invention clearer, the technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] In the description of the embodiments of the invention, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the invention and 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, and therefore should not be construed as a limitation on the invention. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of the embodiments of the invention, "a plurality of" means at least two.

[0032] In the description of the embodiments of the invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the invention according to the specific circumstances.

[0033] As shown in Figures 1-6, an adjustable universal support includes a top base 1, an adjustment part 2, a heightening part 3, and a bottom base 4.

[0034] A partition piece 5 is snapped onto the top base 1. Specifically, the top base 1 and the partition piece 5 are detachably connected by a snap fastener.

[0035] In practice, the adjusting key is used in conjunction with the partition 5. By rotating the adjusting key, the partition 5 can be rotated. By rotating the partition 5 in both directions, the retraction state of the support can be adjusted.

[0036] Furthermore, the top base 1 has a petal-shaped structure, and a grid ring 9 is provided on the outer side of the top base 1.

[0037] The lower end of the top base 1 is located inside the adjustment part 2 and is threadedly connected to the adjustment part 2. Specifically, the lower part of the top base 1 is coaxially provided with a threaded section, the lower end of which is located inside the adjustment part 2 and is threadedly connected to the adjustment part 2. During use, the relative height between the top base 1 and the adjustment part 2 can be adjusted by rotating the threaded section and the adjustment part 2.

[0038] The adjustment part 2 includes a plurality of threaded parts 201 with gradually changing sizes that are sequentially nested. Specifically, the threaded parts 201 are generally columnar structures, and any two adjacent threaded parts 201 are threaded together. In this embodiment, the diameter of the threaded part 201 located on the upper side of the adjacent threaded parts 201 is smaller than the diameter of the threaded part 201 located on the lower side.

[0039] During implementation, the adjustment part 2 is telescopic along the axial direction of the threaded part 201, and the height of the support can be adjusted by the rotation between adjacent threaded parts 201.

[0040] In the specific operation process, when the top base 1 and the adjustment part 2, and the threaded parts 201 in the adjustment part 2, rotate clockwise, they extend to each other, thus increasing their height. When they rotate counterclockwise, they contract to each other, thus decreasing their height.

[0041] The upper threaded component 201 of the adjacent threaded components 201 is provided with a buckle 6 at its bottom end, and the lower threaded component 201 is provided with a straight groove 7 that mates with the buckle 6.

[0042] During implementation, when adjacent threaded parts 201 are rotated, when they are rotated to their highest position, the engagement of the snap 6 and the straight groove 7 can effectively prevent adjacent threaded parts 1 from being easily unscrewed during use, thus avoiding the detachment of the threaded parts 201.

[0043] Furthermore, a tightening part 10 is provided on the upper outer side of the threaded part 201 located at the lower end of the adjustment part 2, which facilitates the threaded connection between the adjustment part 2 and the heightening part 3 during the assembly of the support.

[0044] In practice, the bottom end of the top base 1 is provided with a second buckle 11 that cooperates with the straight groove 7. Similarly, by cooperating with the second buckle 11 on the top base 1 and the straight groove 7 on the corresponding threaded part 201, the top base 1 and the threaded part 201 can be prevented from falling off during use.

[0045] The lower end of the adjusting part 2 is located inside the heightening part 3 and is threadedly connected to the heightening part 3. Specifically, the threaded part 201 located at the lower end of the adjusting part 2 is screwed counterclockwise to the heightening part 3.

[0046] During implementation, when the top base 1 and the adjustment part 2, and the threaded part 201 in the adjustment part 2, are rotated clockwise, the support extends. Since the threaded part 201 at the lower end of the adjustment part 2 and the raising part 3 are tightened counterclockwise, the connection between the adjustment part 2 and the raising part 3 can be guaranteed to be firm. This prevents the raising part 3 and the adjustment part 2 from becoming loose or falling off during the use of the support.

[0047] Furthermore, the upper part of the heightening component 3 is provided with a cross-shaped support component 8, which can improve the structural strength of the heightening component 3 and thus ensure the stability of its overall structure.

[0048] The lower end of the heightening component 3 is threadedly connected to the base 4. Specifically, the lower end of the heightening component 3 is located inside the base 4 and is threadedly connected to the base 4.

[0049] In this embodiment, the heightening member 3 and the base 4 are tightened counterclockwise.

[0050] During implementation, when the top base 1 and the adjusting part 2, and the threaded part 201 in the adjusting part 2, are rotated clockwise to extend the support, the connection between the raising part 3 and the bottom base 4 is ensured by tightening counterclockwise, thus preventing the raising part 3 and the bottom base 4 from becoming loose or falling off during use.

[0051] Meanwhile, during use, the use of the heightening component 3 can be selected according to the actual support height. When the support height is small, the threaded part 201 at the lower end of the adjustment part 2 can be directly threaded to the base 4. At this time, the threaded part 201 at the lower end of the adjustment part 2 and the base 4 are tightened counterclockwise, which can also ensure the firmness and stability of the connection between the threaded part 201 at the lower end of the adjustment part 2 and the base 4 during the unfolding process of the support.

[0052] In a specific implementation of this invention, during installation, the partition 5 is fastened to the top base 1 via a snap fastener, achieving a fixed connection between the two. The lower part of the top base 1 is threadedly connected to the threaded component 201 at the upper end of the adjustment part 2. The adjustment part 2 includes three threaded components 201 that are threadedly connected to each other, and the adjustment part 2 can be extended and retracted along the axis of the threaded components 201. During the unfolding process between the threaded components 201 and between the threaded components 201 and the top base 1, when they are selected to the highest position, the cooperation between the snap fastener 6 and the straight groove 7, and between the snap fastener 11 and the straight groove 7, can achieve the limitation of their relative positions, preventing them from falling off.

[0053] When not in use, the adjustment part 2 can be retracted, so that the upper threaded part 201 can be screwed into the lowermost threaded part 201. At the same time, the lower part of the base 1 can be screwed into the corresponding connected threaded part 201, so that the support can be folded up. Meanwhile, the heightening part 3 can be placed separately and set according to the actual use. This allows the product to be packaged at the lowest height during packaging and transportation, saving packing space and greatly reducing logistics and packaging costs.

[0054] Meanwhile, during use, the highest and lowest heights of the universal support can be adjusted by rotating the top base 1 and the adjustment part 2, as well as the threaded parts 201 in the adjustment part 2, which saves time and improves practicality.

[0055] Furthermore, by tightening the threaded part 201 at the lower end of the adjustment part 2 and the heightening part 3, as well as the lower end of the heightening part 3 and the base 4, counterclockwise tightening can ensure the firmness of the connection of the support during the unfolding process.

[0056] Similarly, since the threaded part 201 at the lower end of the adjustment part 2 is tightened counterclockwise to the raising part 3, and the lower end of the raising part 3 is tightened counterclockwise to the base 4, that is, the threaded part 201 at the lower end of the adjustment part 2 is tightened counterclockwise to the base 4, the structural firmness and stability when the threaded part 201 and the base 4 are directly connected can also be guaranteed.

[0057] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
