[0002] The existing independent exhibition stand structures are all rectangular frame structures built on site through profiles, connecting pieces and locks, etc. On the one hand, due to the different lengths and specifications of the profiles, it is not convenient to uniformly store and transport them; on the other hand, the structure of building the exhibition frame is relatively cumbersome, and a lot of connecting parts are required, which will cause time-consuming and laborious on-site construction, low efficiency, and many connecting parts are prone to missing or confusion, affecting reuse. Therefore, foldable exhibition stands have become a development trend.

[0003] At present, many folding exhibition stands have also appeared on the market, which also have problems such as cumbersome structure, high manufacturing cost, complex combination and construction, and low stability. The company has also studied and applied for patents on several folding exhibition stand structures. For example, the folding exhibition stand described in the application number 202211564212.3, and the cloth frame structure involved in CN202223274167.6, but they are only long side frames that can be folded, and if staggered folding is used, the volume reduction in the width direction is limited, and it can be further developed. Summary of the Invention

[0037] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model. Embodiment 1

[0038] As Figure 1 shown: This embodiment relates to a folding luminous display stand, which includes a frame 1, a corner joint 2, and a floor plate 5. The frame 1 and the corner joint 2 are combined to form a rectangular structure, and the floor plate is fixedly connected to the lower corner joint 2.

[0039] As Figure 2 shown: The frame 1 is provided with at least two frame segments 11, and the frame segments 11 are connected by connectors and form a foldable structure. In this embodiment, each frame is composed of two frame segments 11, but the length of the frame segments can be adjusted or the number of frame segments can be increased as needed to lengthen the length or width of the display stand. Of course, the length of the horizontal frame and the length of the vertical frame can be different, and no examples will be given one by one in this embodiment.

[0040] In addition, it should be noted that: There can be many structural forms of the connectors between the frame segments 11, such as hinges, the intermediate connector structure described in the application number: CN202211564212.3, etc., and no examples will be given one by one in this specification.

[0041] The connector structure adopted in this embodiment is as Figure 4 shown. This connector is a crankshaft hinge piece. The crankshaft hinge piece includes two groups of hinge seats 41, crankshaft hinge plates 42, sliding shafts 44, pin shafts, and a rotating shaft 43. The two groups of crankshaft hinge plates 42 are movably connected in the middle by the rotating shaft 43; the two hinge seats 41 are respectively fixed on the adjacent frame segments 11. The hinge seats are provided with sliding grooves 411. The movable ends of the crankshaft hinge plates 42 can slide in the sliding grooves 411 through the sliding shafts 44, and the fixed ends of the crankshaft hinge plates 42 are connected to the other hinge seat through the pin shafts. The two frame segments 11 are butted together through the crankshaft hinge piece, and a folding angle of 0-180° can be realized, and it is firm and durable.

[0042] In order to prevent the phenomenon of pinching hands when the frame segment 11 is folded and to prevent violent collisions when the frame segment is folded, this crankshaft hinge piece is provided with a damping tension spring 45, one end of which is fixed on the hinge seat 41 and the other end is fixed on the sliding shaft 44. The above purpose is achieved by slowing down the movement of the sliding shaft through the elastic force.

[0043] As Figure 3As shown in the figure, in order to meet the technical requirements such as folding and lighting, the structure of the frame segment 11 is designed as shown in the figure. Two mounting grooves 113 are respectively arranged on the upper and lower sides of the frame segment, and locking holes 1131 are provided in the grooves in a matching manner; lamp grooves 111 are arranged on both sides of the frame segment, and lighting components 115 are arranged in the lamp grooves. Moreover, a cover plate 116 is arranged outside the lamp grooves, and the cover plate can be made of various materials. At the same time, it is also provided with a cloth clamping groove 112, and a mating slot 117 is arranged on the end face along the length direction.

[0044] There are various choices for the lighting component 115. In this embodiment, an LED light strip is adopted.

[0045] As Figure 2 shown in the figure, in this embodiment, a locking component 3 is also arranged between the frame segments 11. After the frame segments are unfolded to form a "one"-shaped straight rod structure, the state is locked through the locking component, so as to form a display rack structure for displaying products. There are many types of locking component structures. For example, a pin structure can be adopted, or a lock structure can be adopted, etc.

[0046] The structure involved in the locking component in this embodiment is as Figure 5 shown: The locking component 3 includes a hook 34, an eccentric handle 32 and a lock housing 31; the lock housing 31 is correspondingly installed in the mounting groove 113 of one frame segment; the eccentric handle 32 is rotationally connected to one side of the lock housing through the cooperation of an eccentric cam 321 and a cylindrical pin 35; one end of the hook 34 is rotationally connected to the eccentric cam 321 through a cylindrical pin 36, and the other end of the hook extends outward from the lock housing and exceeds the lock housing 31; the position where the cylindrical pin 36 is located is above the cylindrical pin 35 and is designed to be inclined towards the handle direction.

[0047] When the frame segments are connected to the frame segment 11, as Figure 3 and Figure 7 shown: A locking component 3 is installed on one frame segment, and its hook 34 extends out of the frame segment, and locking holes 1131 are arranged in the corresponding mounting grooves on the other frame segment. By pressing down the eccentric wrench 32, the hook 34 is tightened against the locking holes 1131, thereby realizing the position locking of the two frame segments after unfolding.

[0048] The above structure is simple, convenient and fast to install, and no tools are required for connection.

[0049] As a further preferred structure of this embodiment, in order to ensure the structural stability of the eccentric handle 32 after being pressed down, as Figure 5As shown in the figure: This embodiment further includes an eccentric handle II 33, which is rotatably connected to the other side of the lock housing through the cooperation of an eccentric cam II and a cylindrical pin II; the handle ends of the eccentric handle I 32 and the eccentric handle II 33 are connected to each other. The specific connection method is as follows: The handle end of the eccentric handle I is provided with an adjustment groove 322, and the eccentric handle II 33 is slidably connected to the adjustment groove 322 of the eccentric handle I through a cylindrical pin IV 37. Through the improvement of the above structure, due to the existence of the eccentric cams at both ends, when the eccentric handle is pressed down, the force acts downward and there is no upward tendency, thus ensuring that the eccentric handle I 32 will not bounce when subjected to vibration or tensile force changes, and ensuring the stability of the structure.

[0050] Regarding the number of the locking components 3 during connection, it can be determined according to the designed number of the installation grooves 113 and the size of the frame. One set can be installed, or two sets can be installed.

[0051] In order to achieve unified installation and design, the connection between the frame 1 and the corner joint 2 in this embodiment of the present case also adopts the locking component 3 as shown in Figure 5 the figure. Of course, the connection between the frame and the corner joint can also adopt various structures, such as locks, screws, etc.; it's just that the locking component designed in this case is more convenient and fast, and the structure is more stable after connection. The specific connection structure: As shown in Figure 10 the figure, the corner joint 2 is correspondingly provided with a locking eye 25; as shown in Figure 8 and Figure 9 the figure: The locking components 3 are distributed in the installation groove on the lower side of the connecting end surface of the frame 1 and the corner joint. The frame and the corner joint are locked and connected through the cooperation of the hook 34 of the locking component and the locking eye 25.

[0052] As shown in Figure 3 and Figure 9 the figure: In order to make the installation more convenient, a positioning plug-in 21 is provided on the butt joint end surface where the corner joint is connected to the frame; a mating slot 117 is provided on the corresponding end surface of the frame. The corner joint and the frame are quickly positioned and connected through the cooperation of the positioning plug-in 21 and the mating slot 117.

[0053] As shown in Figure 9 the figure: Corner light grooves 24 are provided on both sides of the corner joint and correspond to the light grooves 111 on the frame section. The corner light groove 24 is provided with a cover plate I, and a light-emitting component I is provided in the corner light groove 24. The light-emitting component I also adopts an LED light strip. In this way, the unified lighting effect of the entire display rack is achieved, without visual blind spots, and it can emit light from both sides, greatly improving the publicity effect.

[0054] As shown in Figure 2 and Figure 9As shown in the figure: Conductive terminals 22 are provided at both ends of the border segments on the docking end face of the corner joint 2. The light-emitting components within the corner joint, the light-emitting components within the border segments, and the light-emitting components between the border segments are electrically connected to each other through contact of the conductive terminals. That is, a structure for touch conduction is formed between the conductive terminals 22.

[0055] Through the above design, an overall modular design of power supply is achieved, with unified internal wiring, and overall electrical connection can be achieved after assembly, greatly improving the installation effect.

[0056] Regarding the specific conductive terminals, male and female connectors are involved, which belongs to common knowledge and will not be described one by one in this embodiment.

[0057] As a further preferred structure of this embodiment, as Figures 5 - 7 shown in the figure: A displacement adjustment groove 311 is provided at the bottom of the lock housing; a limit rivet 38 is provided, and one end of the limit rivet 38 passes through the displacement adjustment groove 311 and is fixed in the installation groove to limit the sliding range of the lock housing 31; a tension spring 39 is provided, one end of the tension spring 39 is fixed in the installation groove 113 of the border segment, and the other end acts on the lock housing 31; and the tension spring 39 is always in a stretched state.

[0058] Regarding the problem of limiting the lock housing 31 in the installation groove, a design can be adopted where the head of the limit rivet is larger than the width of the displacement adjustment groove, and the number of limit rivets 38 can be increased as needed; alternatively, the installation groove 113 can be designed as a "C" structure, and at the same time, the lock housing structure is adapted to the installation groove, so that the lock housing 31 can be limited to slide within the installation groove 113.

[0059] In this embodiment, the installation groove is designed as a "C" structure, and the entire component realizes surface-to-surface cooperation, which is safer, more reliable, and has strong bearing capacity.

[0060] As Figure 6 and Figure 7 shown in the figure: After the above improvements, by adjusting the position of the locking hole 1131 in the installation groove, the lock housing 31 can be made to straddle into another border segment, so that the lock housing covers the joint between the border segments 11. When the hook 34 cooperates with the locking hole 1131, the two border segments 11 and the lock housing 311 form an integral structure, which greatly improves the stability of the locking structure after unfolding and the bearing capacity of the locking joint.

[0061] In this embodiment, the sliding adjustment range of the locking component 3 is the length range L of the displacement adjustment groove, and at the same time, by adjusting the distance from the limit rivet 38 to the end face of the border segment, the length distance for the lock housing 31 to enter another border segment can be achieved.

[0062] Meanwhile, due to the design of the tension spring 39 and the displacement adjustment groove 311, when the frame is in the folded state, the locking assembly 3 can be ensured to be entirely retracted into the installation groove, avoiding bumps during handling and making it more convenient for carrying and transportation. Embodiment 2

[0063] As Figure 12 shown, in this embodiment, the frame segments are adjusted based on Embodiment 2. The frame 1 is composed of three frame segments 11, and adjacent frame segments are connected by a locking assembly to achieve three-stage foldability.

[0064] The terms "horizontal", "left", "right", "upper", "lower" and similar expressions used in this article are only for detailed description of this embodiment and the accompanying drawings to better understand the design concept of this application.

[0065] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments. From any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description.
