[0034] In one embodiment, please refer to Figures 1 to 7The application provides an exhibition board fixing device 100, which comprises a supporting body 10 and two clamping assemblies 20. The two clamping assemblies 20 are respectively arranged at two ends of the supporting body 10 along the length direction of the supporting body 10, and at least one of the two clamping assemblies 20 can be adjusted along the length direction of the supporting body 10 to clamp or release the exhibition board. The supporting body 10 is provided with a plurality of first clamping portions 15 at intervals along the length direction of the supporting body 10. The clamping assembly 20 which can be adjusted is provided with an abutting piece 30, and the abutting piece 30 is provided with a second clamping portion 31 and is used for abutting the second clamping portion 31 against the surface of the supporting body 10, so that the second clamping portion 31 is clamped and matched with the first clamping portion 15. One of the first clamping portion 15 and the second clamping portion 31 is a clamping convex portion, and the other is a clamping hole.

[0035] The exhibition board fixing device 100 described above is provided with a plurality of first clamping portions 15 at intervals along the length direction of the supporting body 10, and the clamping assembly 20 which can be adjusted is provided with an abutting piece 30. The second clamping portion 31 is abutted against the supporting body 10 by the abutting piece 30. When the clamping assembly 20 is moved, the abutting piece 30 is also moved, so that the second clamping portion 31 is clamped on the first clamping portion 15. Therefore, when the exhibition board is clamped or released, at least one clamping assembly 20 is pushed along the length direction, so that the second clamping portion 31 is tightly clamped on different first clamping portions 15, the distance between the two clamping assemblies 20 is quickly changed, and the clamping and dismounting of the exhibition board are quickly completed. The structure is simple, the operation is convenient, the dismounting efficiency of the exhibition board is improved, the manufacturing cost is reduced, and the like.

[0036] It should be explained that one of the two clamping assemblies 20 can be fixed on the supporting body 10, and the other can be slidably arranged on the supporting body 10. Therefore, when the exhibition board is clamped or released, one of the clamping assemblies 20 can be slid to change the distance between the two clamping assemblies 20. Of course, the two clamping assemblies 20 can be both in a sliding state. The distance between the two clamping assemblies 20 is changed by sliding the two clamping assemblies 20, so that the exhibition board is clamped or released. In a specific embodiment, the two clamping assemblies 20 can both slide along the length direction of the supporting body 10.

[0037] The clamping assembly 20 can be slid on the supporting body 10 in various ways, for example, a guide rail structure is arranged between the clamping assembly 20 and the supporting body 10, or a sliding groove 14 structure is arranged between the clamping assembly 20 and the supporting body 10.

[0038] In addition, when the clamping assembly 20 is adjusted by sliding on the support body 10, the abutting piece 30 drives the second clamping part 31 to abut on the surface of the support body 10, and when the second clamping part 31 moves to the position of the first clamping part 15, the second clamping part 31 is clamped on the corresponding first clamping part 15 under the pressure of the abutting piece 30, so as to realize quick clamping. In order to realize that the abutting piece 30 can drive the second clamping part 31 to abut on the surface of the support body 10 with a certain abutting force, the abutting piece 30 can directly abut on the surface of the support body 10, for example, the second clamping part 31 is a hole structure; or the gap between the abutting piece 30 and the support body 10 can be controlled to be smaller than the protruding height of the second clamping part 31, for example, the second clamping part 31 is a convex structure. In order to make the second clamping part 31 better cooperate with the first clamping part 15, the abutting piece 30 can have a certain elasticity on the clamping assembly 20, for example, the abutting piece 30 can be a metal or plastic sheet structure, which has an up-down elastic bending function on the clamping assembly 20.

[0039] Meanwhile, the shapes of the first clamping part 15 and the second clamping part 31 can have various designs, for example, the first clamping part 15 is a clamping protrusion, and the second clamping part 31 is a clamping hole; or the first clamping part 15 is a clamping hole, and the second clamping part 31 is a clamping protrusion. Specifically, the first clamping part 15 is a clamping hole, and the second clamping part 31 is a clamping protrusion.

[0040] Further, please refer to Figure 3 and Figure 4 The abutting piece 30 includes a pressing sheet 32 and a pulling edge 33. The pressing sheet 32 is arranged at one end of the clamping assembly 20, and the second clamping part 31 is arranged on the surface of the pressing sheet 32 facing the support body 10. The pulling edge 33 is arranged on the pressing sheet 32 and is used to be controlled to make the pressing sheet 32 be lifted in the direction away from the support body 10. It can be known that the pulling edge 33 is arranged on the pressing sheet 32, so that when the display board is disassembled, the pulling edge 33 can be operated, and the pressing sheet 32 is lifted in the direction away from the support body 10, so that the second clamping part 31 is separated from the first clamping part 15, and the convenience of the display board disassembly operation can be further improved.

[0041] It needs to be explained that the pulling edge 33 can protrude and extend in the direction away from the support body 10 relative to the pressing sheet 32, so as to be easily pinched by the operator to lift the pressing sheet 32, so that the second clamping part 31 is separated from the first clamping part 15.

[0042] Alternatively, the connection mode between the pulling edge 33 and the pressing sheet 32 can be various, such as clamping, bolt connection, welding and the like; or the two can be designed as an integrated structure, such as the pulling edge 33 and the pressing sheet 32 are integrally formed by the folding edge 13 technology.

[0043] In one embodiment, please refer to Figure 3 and Figure 4Each clamping assembly 20 comprises a fixing member 21 and a clamping member 23, the clamping member 23 is detachably connected to the fixing member 21, the fixing member 21 is arranged at one end of the support body 10, at least one of the two fixing members 21 can slide along the length direction of the support body 10, and the fixing member 21 adjusted along the length direction is provided with an abutting member 30. In this way, the clamping member 23 and the fixing member 21 are designed to be detachably connected, which is convenient for maintaining the clamping assembly 20.

[0044] The connection mode between the clamping member 23 and the fixing member 21 can be clamping, magnetic attraction, bolt connection, etc.

[0045] Further, please refer to Figure 2 and Figure 3 The support body 10 comprises a bottom plate 11 and a surrounding edge 12 arranged on both sides of the bottom plate 11, the two surrounding edges 12 and the bottom plate 11 form a sliding groove 14 extending along the length direction of the support body 10, each surrounding edge 12 is provided with a bent edge 13 bent towards the inside of the sliding groove 14, and the two sides of the fixing member 21 are respectively provided with clamping edges 22. When the fixing member 21 is arranged in the sliding groove 14, each clamping edge 22 is inserted between the bent edge 13 and the surrounding edge 12. It can be seen that the clamping edges 22 are arranged on both sides of the fixing member 21, and the bent edges 13 are bent towards one side of the sliding groove 14 on the surrounding edges 12 on both sides of the support body 10. In this way, when assembling the clamping assembly 20, the fixing member 21 can be inserted into the sliding groove 14, and the clamping edges 22 of the fixing member 21 can be inserted between the bent edges 13 and the surrounding edges 12, so that the fixing member 21 can slide stably on the support body 10, which is convenient for adjusting the position of the clamping assembly 20. At the same time, it is also conducive to simplifying the design of the sliding cooperation structure between the fixing member 21 and the support body 10, thereby reducing the manufacturing cost of the display board fixing device 100.

[0046] It should be explained that, in order to simplify the preparation process and reduce the cost, the support body 10 and the fixing member 21 can be respectively formed by one-piece bending technology, for example: the two sides of a metal plate are bent upwards; then, the structure bent upwards is bent inward respectively to form the surrounding edge 12 and the bent edge 13, wherein the bent edge 13 has a gap between the end away from the surrounding edge 12 and the bottom plate 11, which is convenient for inserting one side of the fixing member 21 between the bent edge 13 and the bottom plate 11, so that the clamping edge 22 can be inserted between the bent edge 13 and the surrounding edge 12. Similarly, the two sides of the metal plate are bent upwards to form two clamping edges 22, etc.

[0047] In one embodiment, please refer to Figure 5 The clamping member 23 is provided with a buckle 235, the fixing member 21 is provided with a buckle groove 211, and the buckle 235 is clamped in the buckle groove 211. In this way, by cooperating the buckle 235 with the buckle groove 211, the clamping member 23 can be quickly clamped on the fixing member 21, which improves the assembly efficiency.

[0048] The number of the buckle slot 211 and the buckle 235 can be one or multiple. When the number of the buckle slot 211 and the buckle 235 is multiple, they can be arranged one by one.
