[0029] Example 1:

[0030] like Figure 1 , 2In the embodiment shown, each support rod 105 serves a supporting function. In order to ensure the strength of each support rod 105 while reducing its own weight, aluminum alloy tubes, stainless steel tubes, or other profiles can be selected for each support rod 105.

[0031] Each crossbeam 102 is rotatably connected to its end via a connecting sleeve 104 and a support rod 105. Specifically, the body of the connecting sleeve 104 and the end of the crossbeam 102 are fixed with bolts. Each connecting sleeve 104 is fitted onto the outer wall of its respective support rod 105. Under the constraint of the retaining ring 103, each connecting sleeve 104 remains axially fixed at its respective support rod 105. The retaining ring 103 is fixedly connected to its respective support rod 105 by welding, bonding, or pinning. In use, the support rod 105 remains upright under the constraint of each crossbeam 102.

[0032] The tabletop 101 and each support rod 105 are interlocked at the top. Constrained by this interlocking structure, the tabletop 101 is stably placed on top of each support rod 105. The tabletop 101 can be made of injection-molded plastic or use a lightweight metal square tube as a frame, with a thin metal plate on the upper surface of the frame. To enhance the strength of the tabletop 101, reinforcing ribs can be provided at the bottom.

[0033] The suction cup assembly includes several suction cups 113, each suction cup 113 being disposed at the bottom of each support rod 105. During use, each suction cup 113 adheres to the ground, causing the bottom of each support rod 105 to adhere to the ground. Because this portable display stand is lightweight, it prevents movement between the portable display stand and the ground during use.

[0034] In use, by unfolding each support rod 105 and aligning the plug-in component at the top of each support rod 105 with the plug-in component at the bottom of the tabletop 101, the tabletop 101 can be inserted into the top of each support rod 105, making installation relatively convenient. After the exhibition is completed, the tabletop 101 can be pulled out from the top of each support rod 105, and the support rods 105 can be folded up to complete the storage of the portable exhibition stand, thus making it relatively convenient to transport.

[0035] Example 2:

[0036] Based on Embodiment 1, since the tabletop 101 is made of a relatively light material, in order to prevent relative movement between the tabletop 101 and each support rod 105 during use, such as Figure 3 , 4In the illustrated embodiment, an optional form of the insertion structure between the tabletop 101 and each support rod 105 is provided. A locking block 106 is provided at the plug 108 of the insertion structure between the tabletop 101 and each support rod 105. The plug 108 is located at the bottom of the tabletop 101, and a limiting block 109 is located at the top of each support rod 105. A locking block 106 is provided on the outer wall of each plug 108. The bottom of the limiting block 109 has a mounting hole. The body of the limiting block 109 is rotatably connected to the top of the support rod 105 via the mounting hole and a screw. A notch 107 is provided at the limiting block 109 for the locking block 106 to pass through.

[0037] When the top of the tabletop 101 and each support rod 105 is connected, adjust the angle of the limiting block 109 so that the locking block 106 at the plug 108 at the bottom of the tabletop 101 is aligned with the notch 107 at the limiting block 109. The plug 108 can then be inserted into the limiting block 109. After the plug 108 is inserted into the limiting block 109, rotate the limiting block 109. Under the constraint of the limiting block 109, the locking block 106 prevents the plug 108 from coming out of the limiting block 109.

[0038] Example 3:

[0039] Based on Example 1 or 2, such as Figure 2 In the embodiment shown, in order to make the structure between each crossbeam 102 and the support rod 105 more compact and to prevent relative swaying between each crossbeam 102 and the support rod 105 during use, a gasket 110 is provided between the connecting sleeve 104 at the end of each crossbeam 102 and the support rod 105 thereon.

[0040] During installation, the edges of each gasket 110 are chamfered to align the connecting sleeves 104 and the gaskets 110.

[0041] In order to reduce the frictional resistance when each connecting sleeve 104 rotates, the gasket 110 should preferably be made of polytetrafluoroethylene.

[0042] Example 4:

[0043] Based on any of the embodiments 1-3, such as Figure 5 , 6 In the illustrated embodiment, to prevent the suction cups 113 at the bottom of each support rod 105 from sticking to the ground before the portable display stand is fully assembled, each suction cup 113 of the suction cup assembly is movably connected to the bottom of each support rod 105 via the base 111.

[0044] When in use, after the portable display stand is assembled, the suction cups 113 are connected to the bottom of each support rod 105 via the base 111.

[0045] like Figure 5 , 6In the illustrated embodiment, an optional connection between the suction cup 113 and the base 111 is provided. Specifically, the lower part of the base 111 is open, and a cavity is formed inside the base 111 to provide space for the suction cup 113 to create a vacuum. A downwardly extending support rod is provided axially inside the base 111, and a sliding sleeve 112 is slidably connected to the lower part of the base 111. The center of the suction cup 113 is connected to the lower part of the support rod by bolts, snap-fit, or adhesive. The lower edge of the sliding sleeve 112 abuts against the outer edge of the suction cup 113, and a first spring 114 is provided between the sliding sleeve 112 and the base 111.

[0046] In order to make the lower edge of the sliding sleeve 112 and the edge of the suction cup 113 more firmly bonded, the lower edge of the sliding sleeve 112 and the edge of the suction cup 113 are glued together.

[0047] During use, the support rod at the base 111 presses down on the suction cup 113, creating a vacuum inside the suction cup 113. The lower edge of the sliding sleeve 112 squeezes the edge of the suction cup 113, making the suction cup 113 and the ground more tightly connected, preventing air leakage from the edge of the suction cup 113 during use.

[0048] The above-described embodiments are merely preferred embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be covered within the protection scope of this utility model.
