Description

[Technical Field]

[0001] The present invention is in the field of exhibitions and in particular relates to a vertically expandable and vertically foldable exhibition stand. [Background technology]

[0002] With the development of society, businesses increasingly rely on flexible and fast installation of various display frames for product display and promotion at conferences, exhibitions, presentations, etc. Display cross frames and display light boxes are very widely used display equipment. Their main structure is a combination of display frames, canvases, and lights, which can be used to temporarily form a large display screen or be placed independently to form a small promotional panel. This application relates to the independent display stand structure.

[0003] Traditional freestanding exhibition stand structures are rectangular frame structures assembled on-site using profiles, connecting parts, locks, etc. On the one hand, the lengths and dimensions of the profiles are not uniform, making it inconvenient to store and transport them uniformly. On the other hand, the assembly structure of the exhibition frame is relatively complicated, requiring the use of many connecting parts, which makes on-site assembly time-consuming and labor-intensive, and inefficient. In addition, the many connecting parts are easily lost or mixed up, which affects reusability. Therefore, foldable exhibition stands are becoming a trend.

[0004] Similarly, folding exhibition stands currently available on the market suffer from problems such as complex structures, high manufacturing costs, complicated assembly, and low stability. For example, the folding structure formed in Chinese Patent Application No. 202111603921.3 involves a first connecting frame, a first rotating structure, a second rotating structure, and other structures, in which the vertical rod is inverted and folded in half before folding inward. This allows for a compact storage structure when folded in half, but after unfolding, it can be fixed by combining various fixing parts. Therefore, it cannot meet market needs, and it is not possible to achieve the folding storage and telescoping deployment of the entire exhibition stand.

[0005] Furthermore, with regard to freestanding exhibition stands, there is currently no structural form available on the market that allows the display frame to be extended vertically or horizontally, which cannot meet the requirements for use in some situations. Summary of the Invention [Problem to be solved by the invention]

[0006] To overcome the above drawbacks, the present invention provides a folding exhibition stand with a simple structure and easy assembly, which is convenient to transport, does not require customers to assemble the frame, and allows the size of the stand to be flexibly changed. [Means for solving the problem]

[0007] To achieve the above objectives, the technical solutions of the present invention are as follows: The present invention provides a foldable exhibition stand, which includes a display frame, the display frame including a pair of short side frames and at least a pair of long side frames, the foldable exhibition stand further including corner connecting pieces and intermediate connecting pieces, the corner connecting pieces including upper and lower corner connecting pieces, both ends of the long side frame being connected to the upper short side frame and the lower short side frame via the upper and lower corner connecting pieces, the intermediate connecting piece being located at the middle position of the long side frame and dividing the long side frame into two, the long side frame being foldable from the middle towards the inside of the display frame via the intermediate connecting piece, and the both long side frames being folded in half via the corner connecting pieces, and then offset folded and stored in the lower short side frame.

[0008] In a preferred embodiment of this embodiment, the lower corner connecting piece includes a lower corner body, a lower pin shaft, and a lower rotating piece, the lower rotating piece is connected to the lower corner body via the lower pin shaft and can rotate around the lower pin shaft toward the inside of the display frame, the movable end of the lower rotating piece is inserted into the long side frame, one end of the lower pin shaft is based and the other end is inclined downward and toward the inside of the display frame, and is attached to the connecting end of the corner body and the rotating piece, the upper corner connecting piece includes an upper corner body, an upper pin shaft, and an upper rotating piece, and the upper corner connecting piece and the lower corner connecting piece form an axisymmetric structure after being attached to the upper and lower ends of the long side frame respectively.

[0009] In the present invention, the connected long side frames can be folded diagonally in each direction around the rotating shaft in conjunction with each other via the rotating shaft arranged diagonally, thereby achieving the purpose of offset storage after folding the long side frames on both sides in half.

[0010] As a further improvement of the present invention, the downward inclination angle of the lower pin axis is the same as the inward inclination angle of the display frame, and the complementary angles ensure that the long and short side frames are parallel to each other after folding.

[0011] In a preferred embodiment of the present invention, the intermediate connecting part includes an intermediate body and two bifolding parts hingedly connected to both ends of the intermediate body via pins, and the two bifolding parts can rotate around the pins toward the outside of the display frame.

[0012] As a further improvement of the present invention, in order to further enhance the stability of the entire frame, a support rod is included, and both ends of the support rod are engaged and connected to the intermediate body, and are used to limit the folding of the long side frame after it is unfolded.

[0013] In order to reduce the number of parts such as fixed connection parts and assembly connection parts, in the present invention, as an improvement to the frame profile, two insertion holes are provided along the longitudinal direction on the inner end surfaces of the short side frame and the long side frame, and an attachment groove is formed between the two insertion holes.

[0014] As a further improvement of the present invention, lighting components are provided within the mounting grooves to further enhance the lighting effect during the exhibition and create an atmosphere on site.

[0015] In line with the improvement of the profile, in order to facilitate on-site installation, it is only necessary to select a light guide plate, a light bar, etc. as the lighting component and fix it in the installation groove.

[0016] In order to enable the display frame to be extended vertically and foldable at the same time, the present invention additionally designs a middle reversible connecting piece, which is used to connect two or more pairs of long frames. The middle reversible connecting piece includes a middle reversible body and reversible rotating pieces hingedly connected to both ends of the middle reversible body via positioning pins, and the reversible rotating pieces can rotate toward the inside of the display frame around the positioning pins. One end of each of the adjacent long frames on the same side is inserted and connected to the reversible rotating piece, and corresponding middle reversible connecting pieces on both the left and right sides are connected via support rods, which are used to limit the rotation of the middle reversible connecting pieces after the display stand is unfolded.

[0017] After folding, the height of the intermediate body corresponds to the height of the long frame after folding in two, so that each frame can form an optimal parallel position and prevent friction damage to each part.

[0018] In order to further facilitate the electrical connection of the lighting components on both sides of the intermediate connection piece installed in the mounting groove of the long side frame, the lighting components are provided with conductive terminals on the side closer to the intermediate connection piece, and conductive pillars are provided within the conductive terminals, extending toward the intermediate connection piece via springs and protruding from the conductive terminals. Conductive pillar 1, which penetrates the intermediate body of the intermediate connection piece, is fixed at a position corresponding to the conductive pillar, and after the exhibition stand is unfolded, the contact connection between the conductive pillar and conductive pillar 1 realizes the electrical series connection of the lighting components on both sides of the intermediate connection piece.

[0019] The present invention can be directly installed on site if the frame is wide enough, and of course, foot plates can be fixed to the bottom of the lower frame to enhance the stability of the display frame. [Effects of the Invention]

[0020] The advantages of the present invention are as follows: 1. The structural design of this invention is ingenious. By using the corner connecting parts and long side frame design, the entire stand structure can be folded directly once or multiple times, which greatly reduces the volume of the product and makes it easier to transport. 2. The structure of the present invention is stable, and the combined design of the support rod and the long side frame solves the structural stability problem after the display frame is unfolded, which is convenient and reliable. 3. The structure of the present invention is simple, the manufacturing cost is low, and it can be folded and expanded as a whole. It does not require on-site assembly or other auxiliary tools, and can meet the customer's requirements for quick on-site assembly and installation anytime and anywhere, greatly improving installation efficiency, and is convenient and fast. 4. The present invention achieves an offset folding function through the design of corner connectors and long side frames, ensuring that the length of the frames on both sides is not limited by the length of the bottom frame, thereby allowing for flexible changes in the size of the display frame. 5. The present invention further increases the number of long side frames through the intermediate inverted connecting parts, thereby extending the vertical height of the display frame and improving the utilization efficiency of the display frame. At the same time, the frame structure design allows for the direct addition of lighting components, resulting in a superior display effect. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some of the embodiments of the present invention, and all other embodiments that can be obtained by those skilled in the art based on the embodiments of the present invention without any creative work fall within the protection scope of the present invention.

[0023] Example 1 As shown in Figure 1, this embodiment relates to a foldable exhibition stand, and includes an exhibition frame, a leg plate 7, and a support rod 5. The exhibition frame has a rectangular structure and includes a pair of short-side frames 2 and a pair of long-side frames 1. The long-side frames include two long-side frame segments 11 of the same length and an intermediate connecting piece 4. As shown in Figure 1, the corner connecting pieces include an upper corner connecting piece 9 and a lower corner connecting piece 3, and the upper short-side frame is hingedly connected to one end of the long-side frame via the upper corner connecting piece 9, and the lower short-side frame is hingedly connected to one end of the long-side frame via the lower corner connecting piece 3.

[0024] As shown in Figures 2 to 4, the lower corner connection piece 3 includes a lower corner body 31, a lower rotating piece 32, and a lower pin shaft 33. In this embodiment, the lower corner body 31 has connecting end surfaces 1 and 2 311 connected at a 90-degree angle. An insertion protrusion 312 is formed directly on connecting end surface 1 for insertion connection to the short-side frame. Connecting end surface 2 is hingedly connected to the lower rotating piece 32 via the lower pin shaft 33, and a similar insertion protrusion is formed on the movable end of the lower rotating piece 32, which is inserted and connected to the long-side frame segment 11. This allows the lower rotating piece 32 to rotate the connected long-side frame segment 11 90 degrees toward the inside of the exhibition frame around the lower pin shaft 33.

[0025] As shown in Figures 2 and 5, the upper corner connecting piece 9 includes an upper corner body 91, an upper rotating piece 92, and an upper pin shaft 93. The upper corner connecting piece 9 and the lower corner connecting piece 3 are similar in structure, differing only in the inclination directions of the upper pin shaft 93 and the lower pin shaft 33, which ensures that the upper and lower long side frames are folded with an inclination toward the same side. As shown in Figure 7, the upper corner connecting piece 9 and the lower corner connecting piece 3 form an axisymmetric structure after being attached to the upper and lower sides of the long side frame, respectively.

[0026] In this example, the design issue of the inclination angle is discussed in detail using a lower corner connector as an example. As shown in Figures 2 to 4, the upper end surface of the connecting end surface 2 (311) of the lower corner connector 3 has an inclined butt structure, with the left end higher and the right end lower. The lower pin shaft is attached to the connecting end surface 2 (311) by using the left end as the base and inclining downward toward the right end and toward the inside of the display frame. An included angle α is formed between the line on which the lower pin shaft exists and the horizontal plane, and an included angle β is formed between the line on which the lower pin shaft exists and the vertical plane. In this example, the included angles α and β are the same, forming a mutually compensating inclination angle structure that ensures that the long and short frame frames remain parallel to each other after diagonal folding. To minimize the volume after folding, the included angle should be less than 10 degrees. In this example, the included angles α and β are both 3.5 degrees. To ensure that the long-side frame can stand upright after the display stand is unfolded, the mating surface of the lower rotating part that butts against the lower corner body connecting end surface 2 311 is designed to have a corresponding narrow left and wide right structure, while the insert protrusion formed on the movable end of the lower rotating part 32 is connected to the long-side frame 1 in a forward vertical inserting manner. In this way, the lower rotating part 32 can fold the long-side frame segments 11 diagonally in the corresponding direction, so that the long-side frame can stand upright normally after unfolding.

[0027] As shown in Fig. 6, the intermediate connecting piece 4 includes an intermediate body 41 and two bi-folding pieces 42 hingedly connected to both ends of the intermediate body via pins, and the two bi-folding pieces can rotate around the pin axes toward the outside of the display frame. The two long-side frame segments 11 are respectively plug-connected to the two bi-folding pieces 42, thereby realizing the inward folding of the long-side frame. The intermediate body of the intermediate connecting piece is provided with an engagement end 43 for fixedly connecting with the support rod 5 after the display frame is unfolded.

[0028] As shown in Figure 9, in this embodiment, the short-side frame 2 and the long-side frame 1 have the same cross-sectional structure and differ only in length. In this embodiment, the structure will be explained using the short-side frame 2 as an example. Two insertion holes 21 are provided along the length on the inner end surface of the short-side frame, which are used to insert and connect the intermediate connecting piece 4, the corner connecting piece, and the intermediate inverted connecting piece 8. A mounting groove 22 is formed between the two insertion holes, which is used to attach the light-emitting component 6. Fabric clamping grooves 23 are formed on both sides of the short-side frame 2, which are used to securely connect the four sides of the canvas.

[0029] As shown in FIG. 1, the exhibition stand is provided with a leg plate 7, and the leg plate 7 is fixedly connected to the short side frame.

[0030] As shown in Figures 6, 7 and 8, the hinge structure of the intermediate connecting piece 4 is of conventional design, and the four corners of the exhibition stand are connected by special corner connecting pieces designed in this application. Through the axisymmetric upper and lower corner connecting pieces, the left long side frame 1 is folded at an angle from the middle to the rear of the exhibition frame, and similarly, the right long side frame is folded at an angle from the middle to the front of the exhibition frame, so that after both long side frames are folded, they form a non-overlapping structure that is offset forward and backward, overcoming the lateral length limitation of the short side frames.

[0031] 6, in this embodiment, the height of the intermediate body 41 is adapted to the height of the long-side frame 1 after folding in half. Finally, the display frame can be folded into a minimum structural state.

[0032] From this embodiment and the accompanying drawings, it can be seen that the exhibition stand of the present application does not require any tools or auxiliary parts when folding, unfolding or fixing, and does not need to be matched with other parts, making it very quick and convenient to install and fix.

[0033] In this embodiment, support rods are used to limit and stabilize the exhibition stand structure. Of course, support rods may not be used in this application. For example, based on the hinged connection between the intermediate body and the bifoldable parts of the intermediate connecting piece 4, a damper design, engagement design, or tight-fitting design can be added between the two to ensure the relative positional stability between the intermediate body and the bifoldable parts after unfolding. Similarly, the above-mentioned structures can be used for the upper and lower corner connecting pieces to ensure the positional stability of the long-side frame after unfolding. Finally, the canvas can be secured with clips or other fastenings to further strengthen the exhibition stand. However, the above-mentioned damper design, engagement design, tight-fitting design, etc. are common designs and will not be described in further detail.

[0034] Example 2 As shown in Figure 10, based on Example 1, the folding exhibition stand of this example is expanded vertically and includes two pairs of long side frames 1. The exhibition frames incorporate intermediate reversible connecting pieces 8 when expanded.

[0035] As shown in FIG. 12 , the intermediate reversible connecting piece 8 includes an intermediate reversible body 81 and two counter-rotating pieces 82 hingedly connected to both ends of the intermediate reversible body via positioning pins 83. The intermediate reversible body 81 has a fitting hole 84 for mating with the support rod. The counter-rotating piece can rotate toward the inside of the display frame around the positioning pin, and the rotation direction of the counter-rotating piece 82 is opposite to the rotation direction of the bifold piece on the intermediate connecting piece 4. As shown in FIG. 11 , the intermediate reversible connecting piece 8 has a conventional hinge structure, and one end of each of the adjacent long side frames 1 on the same side is inserted and connected to the counter-rotating piece 82. After unfolding, as shown in FIGS. 10 and 11 , the left and right intermediate reversible connecting pieces 8 are fixedly connected via the support rods 5. When folding, the two long side frames on the same side are folded toward the inside of the display frame, and finally, the folded two long side frames are stacked again via the intermediate reversible connecting piece 8 to form a double structure. However, similar to the first embodiment, the frames on both sides are offset from each other after folding.

[0036] The structure of the engagement end 43 provided on the intermediate body is similar to the structure of the fitting opening 84 provided on the intermediate inverted body 81 .

[0037] From this embodiment and the accompanying drawings, it can be seen that the present invention achieves the purpose of quick setup and storage by folding and unfolding the exhibition stand as a whole, and meets the requirements for use in the exhibition field. Furthermore, it can be seen that the length of the frame is not subject to any restrictions and can be used flexibly. In addition, in this application, the structures of the upper and lower short side frames may be different and are determined according to the requirements for use.

[0038] Example 3 As shown in Figures 13 and 14, based on Example 1, the folding exhibition stand of this example optimizes the electrical connection structure between two lighting components mounted within the long-side frame segments, enabling the two lighting components to be electrically connected in series after the frame is unfolded. Specifically, two conductive pillars 45 are fixed to the middle body 41 of the middle connection piece, penetrating the middle body from top to bottom, with both ends of conductive pillar 45 slightly protruding from both sides of the middle body. As shown in Figure 15, a conductive terminal 61 is provided on the side of the lighting component 6 closest to the middle connection piece. Within the conductive terminal 61 are two conductive pillars 611 that extend toward the middle connection piece via springs 612 and protrude from the conductive terminal. After the long-side frame is unfolded, conductive pillars 45 and 611 are aligned and in contact with each other. At the same time, the presence of springs 612 ensures reliable contact between conductive pillars 45 and 611. When the exhibition stand is folded, the conductive pillars separate, ensuring safety between the two lighting components.

[0039] In this embodiment, the lighting component fixed in the mounting groove is a light strip. In this embodiment, a tension strip 421 is further added to the bi-fold part of the intermediate connecting component, thereby ensuring the stability of the connection with the long-side frame segment 11.

[0041] Those skilled in the art will readily appreciate that the present invention is not limited to the details of the exemplary embodiments set forth above, which are to be considered in all respects as illustrative and not limiting. The scope of the present invention is limited by the appended claims, not by the above specification. Accordingly, all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein.
