[0003] The existing display racks are mostly of an integrated structure, supported by a base. A vertically arranged display board is fixedly connected to the base, and then the works are hung on the display board. However, in the outdoor environment, wind may sometimes be encountered, and the wind is likely to blow down the display rack, which is not conducive to the exhibition of works. Content of the Utility Model

[0004] In order to solve the problems in the above background technique, the utility model provides a three-dimensional display rack, which reduces the possibility of the display rack being blown down by the wind and is conducive to the exhibition of works.

[0005] The utility model provides a three-dimensional display rack, which includes a vertically arranged fixed rod and at least one display board. Support rods are respectively fixedly connected to both ends of the fixed rod. At least one rotating rod is connected to each end of the fixed rod. Plug-in rods are respectively fixedly connected to both sides of each display board. The support rod and the rotating rod at the bottom are provided with a first connection hole for the plug-in rod at the bottom to rotate and be inserted. The support rod and the rotating rod at the top are provided with a second connection hole for the plug-in rod at the top to rotate and be inserted.

[0006] By adopting the above technical solution, the support rod and the rotating rod at the bottom support the fixed rod. When installing the display board, move the installation board upward so that the plug-in rod at the top is inserted into the second connection hole, and place the plug-in rod at the bottom above the first connection hole. Then move the display board downward so that the plug-in rod at the bottom is inserted into the first connection hole. The display board can rotate. Hang or paste the works to be displayed on the surface of the display board to display the works. When encountering wind outdoors, the display board rotates, reducing the possibility of the wind blowing down the display rack. At the same time, when there is no wind, it is also convenient for visitors to rotate the display board for browsing, which is conducive to the exhibition of works.

[0007] Furthermore, the display board is a mesh display board.

[0008] By adopting the above technical solution, the display board is of a mesh structure, reducing the resistance of the display board to the wind and reducing the possibility of the display board being blown down.

[0009] Furthermore, a rotating assembly is provided between each rotating rod and the fixed rod, and the rotating rod is rotatably connected to the fixed rod.

[0010] By adopting the above technical solution, when the display rack needs to be used, the rotating rod is opened through the rotating assembly, and then the display board is installed. When the display rack needs to be stored, the display board is removed, and then the rotating rod is folded through the rotating assembly, which has the effect of saving storage space.

[0011] Furthermore, each rotating assembly includes a first U-shaped plate fixedly connected to the fixed rod. A second U-shaped plate is rotatably connected to the end of the first U-shaped plate close to the rotating rod, and the second U-shaped plate is fixedly connected to the rotating rod.

Detailed implementation manners

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0040] The following combines the attached Figure 1 To the attachedFigure 7 This utility model is discussed in detail together with specific embodiments.

[0041] As Figures 1 to 3 As shown, a three-dimensional display rack provided by this utility model includes a fixed rod 1, and support rods 2 are fixedly connected to the bottom end and the top end of the fixed rod 1 respectively.

[0042] Rotating rods 3 are rotatably connected to the bottom end and the top end of the fixed rod 1 respectively. The number of the rotating rods 3 is four. Two rotating rods 3 correspond to the bottom end of the fixed rod 1, and the two rotating rods 3 are arranged oppositely. Two rotating rods 3 correspond to the top end of the fixed rod 1, and the two rotating rods 3 are arranged oppositely. A rotating assembly 4 is provided between each rotating rod 3 and the fixed rod 1, and each rotating rod 3 is connected to the fixed rod 1 through the rotating assembly 4.

[0043] During use, the rotating rod 3 located below is rotated downward through the rotating assembly 4 to unfold the rotating rod 3 below, so that the rotating rod 3 below and the support rod 2 below are in the same plane. The rotating rod 3 located above is rotated upward through the rotating assembly 4 to unfold the rotating rod 3 above, so that the rotating rod 3 above and the support rod 2 above are in the same plane.

[0044] Vertically arranged first connection holes 5 are respectively provided at the end parts of the support rod 2 and the rotating rod 3 located below, and vertically arranged second connection holes 6 are respectively provided at the end parts of the support rod 2 and the rotating rod 3 located above. The three-dimensional display rack further includes a net-shaped display board 7. The number of the display boards 7 is at most four. Plugging rods 71 are fixedly connected to the top and the bottom of each display board 7. The diameters of the first connection holes 5 and the second connection holes 6 are both larger than the diameter of the plugging rod 71.

[0045] The number of the display boards 7 can be selected according to actual needs. When installing the display board 7, the plugging rod 71 at the top is placed below the second connection hole 6, the display board 7 is moved upward to make the plugging rod 71 at the top plugged with the second connection hole 6, the plugging rod 71 at the bottom is placed above the first connection hole 5, and then the display board 7 is moved downward to make the plugging rod 71 at the bottom plugged with the first connection hole 5. The display board 7 can rotate.

[0046] The works to be displayed are hung or pasted on the surface of the display board 7 to display the works. When there is wind outdoors, the display board 7 rotates, reducing the possibility that the wind blows down the display rack. At the same time, when there is no wind, it is also convenient for visitors to rotate the display board 7 for browsing, which is beneficial to the exhibition of the works. When installing four display boards 7, each display board 7 will not collide during the rotation process, and each display board 7 can rotate independently.

[0047] As Figure 1 and Figure 4As shown, each first rotating assembly 4 includes a first U-shaped plate 41 fixedly connected to the vertical side of the fixed rod 1. A second U-shaped plate 42 is rotatably connected to the end of the first U-shaped plate 41 close to the rotating rod 3, and the second U-shaped plate 42 is fixedly connected to the rotating rod 3. The first U-shaped plate 41 is rotatably connected to a first connecting rod 411. The first connecting rod 411 is fixedly connected to a pair of receiving rods 43. The two receiving rods 43 are respectively located on both sides of the first U-shaped plate 41. One end of the receiving rod 43 far from the first U-shaped plate 41 is fixedly connected to a sliding rod 44. A sliding groove 421 penetrating the second U-shaped plate 42 is provided on the side of the second U-shaped plate 42. The sliding rod 44 is placed in the sliding groove 421 and is slidably connected to the sliding groove 421.

[0048] As Figure 4 and Figure 5 shown, the second U-shaped plate 42 is fixedly connected to a second connecting rod 45. The second connecting rod 45 is rotatably connected to a stopper 46. A torsion spring 47 is sleeved on the second connecting rod 45. One end of the torsion spring 47 is fixedly connected to the inner wall of the stopper 46, and the other end of the torsion spring 47 is fixedly connected to the second connecting rod 45. When in the natural state, the end of the stopper 46 close to the first U-shaped plate 41 abuts against the inner wall of the second U-shaped plate 42 close to the rotating rod 3. When the end of the stopper 46 far from the first U-shaped plate 41 is pressed forcefully to make the stopper 46 in a horizontal state, the stopper 46 is placed above the sliding groove 421.

[0049] During the process of opening the rotating rod 3 to make the rotating rod 3 horizontal, the sliding rod 44 slides in the sliding groove 421. During the process of the sliding rod 44 abutting against the stopper 46, the torsion spring 47 is compressed, causing the stopper 46 to rotate. When the sliding rod 44 passes over the stopper 46, the stopper 46, under the action of the torsion spring 47, the end of the stopper 46 passes over the sliding rod 44 and abuts against the inner wall of the second U-shaped plate 42. When the rotating rod 3 has a tendency to rotate towards the side close to the fixed rod 1, the stopper 46 blocks the sliding rod 44, thereby fixing the rotating rod 3.

[0050] As Figures 1 to 5 shown, when it is necessary to store the display rack, first move the display board 7 upward so that the bottom insertion rod 71 is separated from the first connection hole 5, and then move the display board 7 obliquely downward so that the top insertion rod 71 is separated from the second connection hole 6, and the display board 7 can be removed.

[0051] Then press the stopper 46 to make the stopper 46 in a horizontal state. The stopper 46 no longer blocks the sliding rod 44. Rotate the rotating rod 3 towards the side close to the fixed rod 1. The sliding rod 44 slides in the sliding groove 421, fold the rotating rod 3, and then store the display rack. The rotating rod 3 can be folded, which has the effect of saving storage space.

[0052] The second U-shaped plate 42 is provided with a reserved groove 422 which penetrates through a pair of side walls of the second U-shaped plate 42. When the rotating rod 3 is folded, the first connecting rod 411 is placed in the reserved groove 422, so that the rotating rod 3 is as close as possible to the fixed rod 1, saving storage space.

[0053] As Figure 1 and Figure 6 shown, a fixing component 8 is provided between each rotating rod 3 and the fixed rod 1. When the rotating rod 3 is folded, the rotating rod 3 is fixed by the fixing component 8, increasing the stability of the placement after the rotating rod 3 is folded. When it is necessary to open the rotating rod 3, the fixing component 8 releases the restriction on the rotating rod 3, and the rotating rod 3 can be opened.

[0054] As Figure 6 and Figure 7 shown, each fixing component 8 includes a clamping plate 81 fixedly connected to the end of the rotating rod 3. A first fixing plate 82 is fixedly connected to the vertical side wall of the fixed rod 1, and the number of the first fixing plates 82 is correspondingly set with the number of the clamping plates 81. A second fixing plate 83 corresponding to the first fixing plate 82 is also fixedly connected to the vertical side wall of the fixed rod 1. Each first fixing plate 82 is rotatably connected with a clamping block 84, each clamping block 84 is rotatably connected with a clamping hook 85, and each clamping block 84 is provided with a plugging hole 841 for the first fixing plate 82 to be plugged into.

[0055] When the rotating rod 3 needs to be fixed after being folded, rotate the clamping block 84 towards the side close to the rotating rod 3 so that the clamping hook 85 is clamped with the clamping plate 81, and then rotate the clamping block 84 towards the side close to the fixed rod 1 so that the second fixing plate 83 is plugged into the plugging hole 841, and the rotating rod 3 can be fixed.

[0056] When it is necessary to open the rotating rod 3, rotate the clamping block 84 towards the side close to the rotating rod 3 so that the clamping hook 85 is separated from the clamping plate 81, and the restriction on the rotating rod 3 can be released, and the rotating rod 3 can be opened.

[0057] The second fixing plate 83 is provided with a fixing hole 831. After the second fixing plate 83 is plugged into the plugging hole 841, a wire or a lock can be plugged into the fixing hole 831 to reduce the possibility of the second fixing plate 83 being separated from the plugging hole 841. Separating the wire or the lock from the fixing hole 831 can rotate the clamping block 84.

[0058] As Figure 1 and Figure 2As shown in the figure, universal wheels 9 with locking functions are fixedly installed on both the bottom support rod 2 and the rotating rod 3. When it is necessary to move the display rack after the rotating rod 3 is opened, push the fixed rod 1, and the universal wheels 9 rotate, which has the effect of facilitating the movement of the display rack. After the display rack is moved to the designated position, lock the universal wheels 9, and then fix the display rack. When it is necessary to move the display rack, unlock the universal wheels 9, and then the display rack can be moved.

[0059] A reinforcing rod 21 is fixedly connected between the support rod 2 and the fixed rod 1, and the reinforcing rod 21 increases the stability of the connection between the support rod 2 and the fixed rod 1.

[0060] The implementation principle of a three-dimensional display rack provided by the present utility model is as follows: Rotate the clamping block 84 towards the side close to the rotating rod 3 to separate the hook 85 from the clamping plate 81, and then rotate the rotating rod 3 to open the rotating rod 3. Move the display board 7 upwards so that the plugging rod 71 at the top is plugged into the second connection hole 6, and then move the display board 7 downwards so that the plugging rod 71 at the bottom is plugged into the first connection hole 5 to complete the installation of the display board 7.

[0061] Remove the display board 7, press the stop block 46, rotate the rotating rod 3 to fold the rotating rod 3, engage the hook 85 with the clamping plate 81, rotate the clamping block 84 so that the second fixed plate 83 is plugged into the plugging hole 841, and fix the rotating rod 3 to store the display rack.

[0062] The above further describes the present utility model with the aid of specific embodiments. However, it should be understood that this specific description should not be construed as a limitation on the essence and scope of the present utility model. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present utility model.
