Description

Technical Field

[0001] This utility model relates to the field of exhibition and display technology, specifically to the setting of display stands, and more particularly to a folding display stand. Background Technology

[0002] The ability to flexibly and quickly set up various display frames for product display and promotion in conferences, exhibitions, and other settings is increasingly favored by businesses. Display frames, light boxes, and promotional display stands are widely used exhibition equipment. Their main structure involves combining display frames with lighting and other components. They can be temporarily assembled into large exhibition screens or placed independently to form small promotional displays.

[0003] Patent document CN216353185U discloses a folding display lightbox, in which a long profile and a short profile are connected by a rotation, and the length of the long profile is more than twice the length of the short profile, thereby achieving folding and storage of the lightbox. In this patent, due to structural limitations, the length of the long profile must be more than twice the length of the short profile, which significantly restricts the size of the folding display stand. Increasing the height of this type of display stand requires a corresponding increase in length, making it unsuitable for various usage scenarios. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the technical problem of the difficulty in folding folding display racks in the prior art, this utility model provides a folding display rack that is not limited by length and height, and is easy to fold and store.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a folding display stand, including a pair of long frames and a pair of short frames. The long frames include a first frame and a second frame. The first frame is hinged to the short frames through a first corner connector. The second frame is hinged through a second corner connector. The first frame and the second frame are hinged through an intermediate corner connector. The two intermediate corner connectors have a height difference in the vertical direction. The second frame is folded inward on the short frames through the second corner connector. The first frame is folded downward on the second frame through the first corner connector and the intermediate corner connector.

[0006] This utility model of a folding display rack has a vertically offset arrangement of the middle corner connectors of a pair of long frames, so that the pair of long frames form a Z-shaped folding and storage structure during the folding process, avoiding interference of the long frames when folding and facilitating folding and storage.

[0007] Furthermore, the length of the second border is less than the length of the short border, and the length of the first border is greater than or equal to the length of the short border. Thus, a folded structure can be formed by stacking the short border, the second border, and the first border in sequence.

[0008] Furthermore, in the folded state, the first corner connector, the second corner connector, and the middle corner connector are arranged at intervals along the inward direction of the folded display stand.

[0009] Furthermore, in order to ensure the stability of the folding display stand in the unfolded state, the intermediate corner connector includes a first insertion body and a second insertion body. The first insertion body and the second insertion body are inserted into the first frame and the second frame. The first insertion body has a boss, and the second insertion body has a groove. When the folding display stand is unfolded, the boss abuts against the groove.

[0010] Furthermore, in order to avoid a gap between the first and second borders in the unfolded state, after the first and second borders are unfolded, the first and second borders cover the first and second plug-in bodies, and the first and second borders are joined together to form a plane, so that there is only a linear gap between the first and second borders.

[0011] Furthermore, in order to enable the first frame and the second frame to be folded relative to each other without gaps after folding, an alternately arranged connecting plate is connected between the first plug-in body and the second plug-in body. The middle parts of the connecting plates are rotatably connected by a first rotating shaft. One end of the connecting plate is rotatably connected to the first plug-in body or the second plug-in body by a second rotating shaft, and the other end of the connecting plate slides within the first plug-in body or the second plug-in body by a sliding shaft.

[0012] Furthermore, in order for the display stand to be foldable, the pair of long borders are arranged symmetrically at the center.

[0013] Furthermore, in order to allow the short frame, the first frame, and the second frame to be stacked, the first corner connector has an extension connected to the short frame, the pivot of the first corner connector is located on the extension, and the length of the extension is greater than or equal to the sum of the thicknesses of the first frame and the second frame.

[0014] Furthermore, in order to enable the display stand to be folded quickly, the pivot of the first corner connector and the pivot of the second corner connector have a height difference in the vertical direction.

[0015] Furthermore, in order to achieve the display effect by setting up light strip grooves, the short frame, the first frame, and the second frame have light strip grooves in the middle.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The present invention relates to a folding display rack, which has a staggered middle corner connector. This allows the unfolded folding display rack to be turned into a Z-shaped state before being folded, making it easy to fold and store. At the same time, the staggered middle corner connector allows the first frame to have extended space, which can increase the height of the display rack without changing the width of the rack, thus expanding its usage scenarios.

[0018] 2. The folding display stand of this utility model has a protrusion and groove structure on the middle corner connector. When the folding display stand is unfolded, the long side frame can be supported by the middle corner connector to ensure the stability of the structure when the display stand is unfolded.

[0019] 3. The folding display rack of this utility model has an extension on the first corner connector. The first and second side frames on the opposite side of the extension provide a space to accommodate each other, ensuring that each frame can be stacked sequentially in a vertical manner.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model 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 of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 this utility model based on the specific circumstances.

[0034] like Figure 1A folding display stand includes a pair of long frames and a pair of short frames 3, with the pair of long frames arranged symmetrically at the center. The long frames include a first frame 1 and a second frame 2. The first frame 1 is hinged to the short frames 3 via a first corner connector 4, and the second frame 2 is hinged via a second corner connector 5. The first frame 1 and the second frame 2 are hinged via intermediate corner connectors 6. The two intermediate corner connectors 6 have a height difference in the vertical direction. The first corner connector 4 and the second corner connector 5 have identical structures, and since they are existing connectors, they will not be described in detail here.

[0035] Folding display stand in open state Figure 2 As shown. Folding display racks require [further details needed] during storage. Figure 3 and Figure 4 In the folded state, the second frame 2 is first folded inward through the second corner connector 5 to form a shape as shown. Figure 3 As shown, continue folding until the second frame 2 is folded inward over the short frame 3 via the second corner connector 5, forming the shape shown. Figure 4 As shown, the first frame 1 is then folded downwards onto the second frame 2 via the first corner connector 4 and the middle corner connector 6, forming the shape shown. Figure 5 The state shown.

[0036] Specifically, the length of the second border 2 is less than the length of the short border 3, and the length of the first border 1 is greater than or equal to the length of the short border 3. The second border 2 needs to be folded over the short border 3, so the length of the second border 2 must be less than the length of the short border 3.

[0037] Preferably, in the folded state, the first corner connector 4, the second corner connector 5, and the middle corner connector 6 are arranged at intervals along the inward direction of the folded display stand. Because the middle corner connector 6 is staggered and the first frame 1 and the second frame 2 have different lengths, the first corner connector 4, the second corner connector 5, and the middle corner connector 6 have different positions in the vertical and horizontal directions, allowing the length of the first frame 1 to vary.

[0038] Preferably, the pivot of the first corner connector 4 and the pivot of the second corner connector 5 have a height difference in the vertical direction. The first corner connector 4 has an extension 41 connected to the short frame 3. The pivot of the first corner connector 4 is located on the extension 41. The length of the extension 41 is greater than or equal to the sum of the thicknesses of the first frame 1 and the second frame 2. The extension 41 accommodates the first frame 1 and the second frame 2, ensuring the folding effect.

[0039] Example 2, based on Example 1, such as Figures 6 to 8As shown, the intermediate corner connector 6 includes a first insertion body 61 and a second insertion body 62. The first insertion body 61 and the second insertion body 62 are inserted into the first frame 1 and the second frame 2. The first insertion body 61 has a boss 611. The second insertion body 62 has a groove 621. When the folding display rack is unfolded, the boss 611 abuts against the groove 621. Through the cooperation of the groove 621 and the boss 611, the first insertion body 61 and the second insertion body 62 can support each other in the unfolded state, thereby ensuring a stable connection between the first frame 1 and the second frame 2.

[0040] Specifically, when the first frame 1 and the second frame 2 are fully unfolded, they completely cover the first insertion body 61 and the second insertion body 62. Furthermore, the first frame 1 and the second frame 2 are joined to form a plane, resulting in only a linear gap between them. The intermediate corner connector 6 ensures that the first frame 1 and the second frame 2 have only a linear gap after unfolding, preventing the intermediate corner connector 6 from being exposed; that is, no connectors are visible when unfolded.

[0041] Preferably, an alternately arranged connecting plate 63 is connected between the first plug-in body 61 and the second plug-in body 62. The middle parts of the connecting plates 63 are rotatably connected by a first rotating shaft 64. One end of the connecting plate 63 is rotatably connected to the first plug-in body 61 or the second plug-in body 62 by a second rotating shaft 65. The other end of the connecting plate 63 slides within the first plug-in body 61 or the second plug-in body 62 by a sliding shaft 66.

[0042] In Example 3, based on Example 2, the short frame 3, the first frame 1, and the second frame 2 have LED strip grooves in their middle sections. These grooves can accommodate LED strips to ensure optimal display quality.

[0043] Example 4 has the same structure as Example 2, except that the length of the first frame 1 is further increased, and the height difference between the intermediate corner connectors 6 is increased, such as... Figure 9 As shown, because the middle corner connector 6 is offset, lengthening the first frame 1, while keeping the lengths of the short frame 3 and the first frame 1 unchanged, will cause the entire folding display stand to stretch to the left and right. Therefore, the length of the first frame 1 is not limited by the second frame 2 and the short frame 3. The overall height of the folding display stand can be changed simply by increasing the length of the first frame 1 while keeping the width of the display stand constant. This makes it easier to adjust the size of the folding display stand and is suitable for different scenarios.

[0044] In summary, this utility model of a folding display rack is not limited by length or height, and is easy to fold and store.

[0045] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
