[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached Figures 1-7 , and it is obvious that the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As shown in the figure, a multi-functional display rack device includes a base plate 1 and a plurality of display plates 2. A fixed support plate 11 is fixedly arranged on the base plate 1. A folding support plate 3 is hinged on the fixed support plate 11. The folding support plate 3 is sequentially formed by hinging a plurality of folding sub-plates 31. The hinged parts at the upper and lower ends of the folding sub-plate 31 are respectively located on the front and back surfaces of the folding sub-plate 31. Clamping grooves 311 are formed at the upper ends of the fixed support plate 11 and the folding sub-plate 31. A clamping plate 312 is fixedly arranged at the lower end of the folding sub-plate 31. A clamping protrusion 313 that matches the clamping groove 311 and is clamped into the clamping groove 311 is formed on the clamping plate 312. A fixed column 111 is formed at each of the left and right ends of the fixed support plate 11. A folding column 314 is formed at each of the left and right ends of the folding sub-plate 31. The fixed column 111 and a plurality of folding columns 314 are vertically aligned to form a support column 4. Two sliding sleeves 21 that match the support column 4 and are respectively slidably sleeved on the two support columns 4 are formed on the display plate 2. Adjacent display plates 2 are connected by two crossed transmission connecting rods 5. A sliding groove 51 is formed on the transmission connecting rod 5. A transmission column 27 that matches the sliding groove 51 and is kept in the sliding groove 51 is fixedly arranged on the sliding sleeve 21. A first pull rod 6 is fixedly arranged on the uppermost display plate 2. A first locking rod 61 is inserted through the first pull rod 6. A locking hole 315 that matches the first locking rod 61 is formed on the uppermost folding sub-plate 31. The locking rod is inserted into the locking hole 315.

[0025] In the above structure, such as Figure 1 , Figure 2The figure shows the unfolded state of the display rack device. In this state, a plurality of display boards 2 are spaced apart in the longitudinal direction and are used to place items for display or demonstration. The implementation method is that when two adjacent folding sub-boards 31 are turned over to meet at the ends, the snap-in plates 312 that are turned over with the folding sub-boards 31 drive the snap-in protrusions 313 to be snapped into the snap-in grooves 311. The relative rotation of the two adjacent folding sub-boards 31 is limited by the cooperation between the snap-in protrusions 313 and the snap-in grooves 311, so that a plurality of folding sub-boards 31 are spliced ​​up and down to form a folding support plate 3. When the bottom folding sub-board 31 is turned over to meet at the end of the fixed support plate 11, Similarly, the relative rotation of the bottom folding sub-plate 31 and the fixed support plate 11 is limited by the cooperation of the clamping protrusion 313 and the clamping groove 311, that is, the relative rotation of the folding support plate 3 and the fixed support plate 11 is limited, so that the fixed support plate 11 and the folding support plate 3 are spliced ​​to form an integral plate-like structure. At the same time, the fixed column 111 and the folding columns 314 are aligned up and down to form a support column 4, so that the sliding sleeve 21 can slide longitudinally on the support column 4, and then the top display board 2 is lifted upward by the first pull rod 6, and the display board 2 makes the transmission column 27 move in the sliding groove 51 through the action of the transmission connecting rod 5. When the display rack 2 is in the state of being distributed at intervals, the other display boards 2 are driven to move away from each other and spread out, so that the display boards 2 are distributed at intervals on the support column 4. Then, the first locking rod 61 is inserted into the locking hole 315. The first locking rod 61 cooperates with the locking hole 315 to limit the longitudinal movement of the first pull rod 6, and then the longitudinal sliding of the display board 2 on the support column 4 is limited, so that the display boards 2 are kept in a state of being distributed at intervals and can support the items placed on the display board 2 for display or demonstration. When it is necessary to store and transport the display rack, the first locking rod 61 is pulled out of the locking hole 315, and the first pull rod 6 is pulled out of the locking hole 315. The rod 6 pushes the top display board 2 to slide downward, and the display board 2 drives the other display boards 2 to approach each other and slide downward through the action of the transmission connecting rod 5, so that the sliding sleeves 21 of several display boards 2 slide onto the fixed pillars 111, so that several display boards 2 are stacked on the base plate 1, and then the clamping plate 312 is bent to make the clamping protrusion 313 withdraw from the clamping groove 311 to release the relative rotation limit between the two adjacent folding sub-boards 31 and the bottom folding sub-board 31 and the fixed support plate 11, so that the several folding sub-boards 31 are folded in the opposite direction in turn, and finally folded and placed on the top display board 2, so that the display rack device is in the following state. Figure 7 The storage state shown reduces the overall volume of the display rack device, making it easier to store and transport. When switching between the expanded state and the storage state, there is no need to disassemble or assemble additional components, which facilitates operation and avoids loss of components, thereby facilitating the use of the display rack device.

[0026] Additionally, based on the above structure, a second pull rod 7 is fixedly arranged on the lowermost display board 2. A second locking rod 71 matching the locking hole 315 is inserted through the second pull rod 7. A plurality of longitudinally distributed locking holes 315 are formed on both the fixed support board 11 and the folding sub-board 31. When the first pull rod 6 unfolds a plurality of display boards 2 through the transmission connecting rod 5, by inserting the second locking rod 71 into the locking hole 315, the longitudinal movement of the second pull rod 7 is limited, and thus the longitudinal sliding of the lowermost display board 2 is limited. Cooperating with the limitation of the longitudinal sliding of the uppermost display board 2 by the first locking rod 61, the unfolded plurality of display boards 2 are fixed at a certain height. Moreover, by inserting the first locking rod 61 and the second locking rod 71 into the locking holes 315 at different height positions, the height of the display board 2 can be adjusted, and the distance between two adjacent display boards 2 can also be adjusted to meet the placement requirements of different display or demonstration items, having better applicability.

[0027] Additionally, based on the above structure, a first handle 62 is fixedly arranged on the first locking rod 61 on one side of the first pull rod 6, and a first spring 63 is sleeved on the first locking rod 61 between the first pull rod 6 and the first handle 62. The first locking rod 61 has a tendency to slide towards the direction where the locking hole 315 is located under the action of the first spring 63. A second handle 72 is fixedly arranged on the second locking rod 71 on one side of the second pull rod 7, and a second spring 73 is sleeved on the second locking rod 71 between the second pull rod 7 and the second handle 72. The second locking rod 71 has a tendency to slide towards the direction where the locking hole 315 is located under the action of the second spring 73. The first spring 63 and the second spring 73 respectively make the first locking rod 61 and the second locking rod 71 have a tendency to slide towards the direction where the locking hole 315 is located, enabling the first locking rod 61 and the second locking rod 71 to be more stably maintained in the locking hole 315 after being inserted into the locking hole 315, thus ensuring the stability of the plurality of display boards 2. When it is necessary to operate the first pull rod 6 or the second pull rod 7 to switch the state of the display rack device, while holding the first pull rod 6 or the second pull rod 7, the first handle 62 or the second handle 72 is buckled, and then the first locking rod 61 or the second locking rod 71 can be driven to withdraw from the locking hole 315, making the operation more convenient.

[0028] Additionally, based on the above structure, positioning protrusions 316 and positioning holes 317 that match each other are respectively formed on the opposite end faces of two adjacent folding columns 314. When a plurality of folding columns 314 are aligned vertically, the positioning protrusion 316 is snapped into the positioning hole 317. Through the cooperation of the positioning protrusion 316 and the positioning hole 317, the upper and lower adjacent folding columns 314 can be accurately aligned to form the support column 4, thereby ensuring the smoothness of the sliding sleeve 21 sliding on the support column 4 and facilitating the operation during the state switching of the display rack device.

[0029] In addition, on the basis of the above structure, a rotating cavity 22 with an upper end opening is formed on the display board 2, and a rotating disk 23 with an upper end protruding from the rotating cavity 22 is rotatably arranged in the rotating cavity 22. A motor 24 transmission-connected to the rotating disk 23 is arranged below the display board 2. After the items to be displayed or demonstrated are placed on the display board 2, they come into contact with the upper end of the rotating disk 23. The motor 24 drives the rotating disk 23 to rotate, which can drive the items to rotate, thereby facilitating a more comprehensive display or demonstration of the items and facilitating the use of the display rack device.

[0030] In addition, on the basis of the above structure, a plurality of swinging rods 25 are rotatably arranged under the display board 2. In order to make the swinging rod 25 have a certain damping when swinging, a friction plate tightly against the swinging rod 25 is sleeved on the rotating shaft of the swinging rod 25. A spotlight 26 is arranged on the swinging rod 25 through a ball head, that is, a ball head is fixedly arranged on the spotlight 26, and the ball head is arranged on the swinging rod 25. The spotlight 26 can be driven to swing by swinging the swinging rod 25. When the display board 2 is stored, the spotlight 26 is swung upward and stored inside the display board 2 to facilitate the stacking and storage of several display boards 2. When the display board 2 is unfolded to display or demonstrate items, the spotlight 26 is swung downward and the angle of the spotlight 26 is adjusted through the ball head so that the spotlight 26 shines on the displayed or demonstrated items, thereby achieving a better display or demonstration effect.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
