DETAILED DESCRIPTION

[0031] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0032] Based on the concept of this application, combined with Figures 1 to 5 This document describes an embodiment of a portable innovation and entrepreneurship guidance display board storage device. Specifically, the device is constructed as a split structure, comprising three components: a storage box 2, a banner storage component 5, and a limiting component 6. By providing multiple storage boxes 2 and banner storage components 5 corresponding to each storage box 2, and fixing the storage boxes 2 and their corresponding banner storage components 5 together with the limiting components 6, the device automatically unlocks the limiting component 6 corresponding to the product when a customer removes it, thereby unlocking the corresponding banner storage component 5. This allows the banner for that product to be extracted and displayed separately, reducing interference with other products during the display process.

[0033] Please refer to Figures 1 to 5 A portable innovation and entrepreneurship guidance display board storage device, including a storage cabinet 1, a storage box 2, and a banner storage component 5;

[0034] The inner side of the storage cabinet 1 has multiple storage boxes 2 arranged in a matrix, and multiple connecting rods 3 are hinged between the multiple storage boxes 2. The storage box 2 is formed by at least three side plates 21, and the multiple side plates 21 are rotatably connected to the bottom surface of the storage box 2. Magnetic components 22 are fixed between the multiple side plates 21.

[0035] The front end of the storage cabinet 1 is provided with a display opening 101 that passes through the storage cabinet 1. A banner storage component 5 is fixed to the outer wall of the storage cabinet 1. A spring-loaded spring 51 is rotatably provided on the inner side of the banner storage component 5. A limit component 6 is fixed on the inner side of the banner storage component 5. Limit holes 211 are provided through the side plates 21 located at the front and rear ends of the storage box 2. The limit component 6 is provided through the side plates 21 at the front and rear ends of the storage box 2.

[0036] When in use, when storing, the staff rotates the storage box 2 inward around the connection point with the bottom surface. Multiple side panels 21 are attracted to each other through the magnetic components 22 on the side walls to form a three-dimensional shape. The staff can put the products into different storage boxes 2, and then rotate multiple storage boxes 2 along the connecting rod 3 and stack them on top of each other in the storage cabinet 1, thereby reducing the volume occupied by the storage boxes 2 and making them easy to move.

[0037] When it is necessary to display the products, the top storage box 2 is dragged to move towards the side wall. Due to the hinging of the plurality of storage boxes 2 through the connecting rods 3, the plurality of storage boxes 2 are arranged side by side from top to bottom. Compared with the plurality of separate storage boxes 2, the plurality of storage boxes 2 are conveniently and quickly arranged. At the same time, the side plates 21 of the plurality of storage boxes 2 are fixed through the magnetic components 22. In order to improve the viewing experience of customers, the plurality of side plates 21 can be unfolded outward to form a multi-level display platform, so as to enhance the space utilization and visual hierarchy, and greatly improve the convenience of self-help reading of the audience, while maintaining the stable storage state of other storage boxes 2.

[0038] At the same time, when the display is about to end, the staff will put the products into the storage box 2 in advance and return to the storage cabinet 1, or when the display space is too small, the plurality of storage boxes 2 are arranged in a row in the storage cabinet 1. At this time, if an audience wants to take out one of the products for observation, if the plurality of storage boxes 2 are arranged again, the plurality of storage boxes 2 need to be stored again. The audience can drag the side plate 21 at the front end of the storage box 2 forward and make the side plate 21 at the front end rotate along the connection between the bottom of the storage box 2 until the upper end surface of the side plate 21 at the front end is in the same plane as the bottom surface of the storage box 2, so as to open the storage box 2. At this time, the remaining side plates 21 on the storage box 2 are blocked by the inner wall of the storage cabinet 1, so as to limit the rotation of the remaining side plates 21. After the side plate 21 at the front end is unfolded, the magnetic attraction of the magnetic component 22 is weakened, so as to improve the stability of the storage box 2. At the same time, after the side plate 21 at the front end is rotated forward, the limiting component 6 can release the banner storage component 5 corresponding to the storage box 2. At this time, the staff can individually pull out the spring 51 corresponding to each product, and further explain to the audience. The separation design of “physical product + information carrier” not only maintains the integrity of product display, but also supports flexible knowledge transmission, improves the depth and interactivity of popular science or business display.

[0039] Please refer to Figure 1 and Figure 5 The side wall edge of the storage cabinet 1 is provided with a sliding groove 102, and the inner side of the sliding groove 102 is slidably provided with a baffle 4. The movement path of the baffle 4 is the same as the movement path of the sliding groove 102.

[0040] In use, after the products are stored, the two side edges of the baffle 4 are inserted along the inner wall of the sliding groove 102 until the bottom surface of the baffle 4 is in contact with the bottom surface of the storage cabinet 1. At this time, the inner wall of the baffle 4 is in contact with the outer wall of the storage box 2, and the side plates 21 of the storage box 2 are fixed and limited, which is conducive to improving the stability of the connection between the side plates 21 of the storage box 2 during the transfer process.

[0041] The side plate 21 of the storage box 2 is made of transparent aluminum material, so that the shape of the internal product can be observed from the outside even when the storage box 2 is stored in the storage cabinet 1, thereby facilitating display, and in the case of a small display space, the storage box 2 can serve as a display stand.

[0042] Please refer to Figures 1 to 3 The side plate 21 of the same storage box 2 and the bottom surface of the storage box 2 are provided with a rotating shaft 20, and the side plate 21 is formed into a rotating structure through the rotating shaft 20.

[0043] By enabling the side plate 21 to rotate around the rotating shaft 20 as the center, the stability of the rotation of the side plate 21 is improved.

[0044] Please refer to Figure 2 and Figure 3 The magnetic assembly 22 includes a magnet 221 and an iron sheet 222, the inner wall of the front and rear end side plate 21 is fixed with the iron sheet 222, and the inner wall of the left and right end side plate 21 is fixed with the magnet 221, and the position of the iron sheet 222 corresponds to the position of the magnet 221.

[0045] When the plurality of side plates 21 are rotated upward along the connection with the bottom surface of the storage box 2, the storage box 2 forms a three-dimensional state, at this time the iron sheet 222 on the front and rear end side plate 21 is tightly attached to the magnet 221 through magnetic force, and the plurality of side plates 21 are not inclined outward due to the adsorption of magnetic force, realizing the functions of quick positioning and self-locking when the storage box 2 is assembled in three-dimensional state, forming a stable magnetic attraction closing system between the side plates 21, effectively preventing the side plates 21 from loosening due to external force or gravity deviation, and allowing controllable separation in the horizontal direction while ensuring stable connection in the vertical direction of the side plates 21 through differential layout of the magnet 221 and the iron sheet 222, which not only ensures the stability of the storage state, but also facilitates users to quickly disassemble and fold through lateral sliding, and meets the dual needs of structural strength and use convenience.

[0046] Please refer to Figures 3 to 5 The banner storage assembly 5 includes a clock spring 51, a storage cylinder 52 and a fixed cylinder 53, a plurality of storage cylinders 52 are fixed at the rear end of the storage cabinet 1, and the positions of the storage cylinders 52 correspond to the positions of the storage boxes 2, the inner side of the storage cylinder 52 is fixed with a rotating cylinder 521, the outer side of the rotating cylinder 521 is wound with the clock spring 51, and the end of the clock spring 51 away from the storage cylinder 52 is fixed with the fixed cylinder 53.

[0047] When in use, one end of the clockwork spring 51 is fixed outside the rotating drum 521, the other end is connected with the display card, the locking state of the limiting assembly 6 is released, the display card is pulled out, the clockwork spring 51 is stretched by external force (manual stretching), the elastic potential energy is stored, the display card is pulled out as far as possible, the display is convenient, at the same time, the clockwork spring 51 keeps tension, when the hand is released, the clockwork spring 51 releases the elastic potential energy, drives the display card to roll back around the center rotating drum 521, which is beneficial to reduce the operation complexity of manual rolling, the structure is similar to that of a tape measure, in addition, the closed storage structure of the clockwork spring 51 effectively isolates dust erosion, prolongs the service life of the elastic element, at the same time, the modular design is convenient for independent disassembly, maintenance and maintenance of the single display card, and the scene adaptability is significantly improved.

[0048] Please refer to Figures 3 to 4 The limiting assembly 6 comprises a support frame 61, a rubber cylinder 62, a locking structure 63 and a connecting rope 64, the support frame 61 is fixed on the outer wall of the storage cabinet 1, the rubber cylinder 62 is fixed on the inner side of the support frame 61, the locking structure 63 is slidably arranged on the inner side of the support frame 61, the rubber cylinder 62 and the locking structure 63 are respectively located on the two sides of the clockwork spring 51, the connecting rope 64 is fixed on the outer side of the locking structure 63, and one end of the connecting rope 64 away from the rubber cylinder 62 penetrates through the limiting hole 211.

[0049] When in use, the clockwork spring 51 is clamped by the rubber cylinder 62 and the locking structure 63, the display card is limited by the friction force among the three, the position of the clockwork spring 51 is limited, so that the clockwork spring 51 is not withdrawn in advance when the audience does not complete observation, and the friction force between the clockwork spring 51 and the locking structure 63 is increased by the rubber cylinder 62, which is beneficial to improve the locking force of the locking structure 63. The limiting assembly 6 forms a dynamic adjustable two-way friction damping system through the elastic deformation of the rubber cylinder 62 and the sliding clamping design of the locking structure 63, which can provide a progressive resistance lock when the display card is unfolded, ensure the stable storage and accurate release of the elastic potential energy of the clockwork spring 51, and realize the hovering of the display card at any position through the friction self-locking after the external force is removed, thereby avoiding the accidental retraction caused by spring rebound inertia.

[0050] Please refer to Figure 4 The support frame 61 is provided with a guide groove 611 on the two sides, and the locking structure 63 is slidably arranged in the inner side of the guide groove 611.

[0051] The locking structure 63 comprises a locking cylinder 631 and a return spring 632, the locking cylinder 631 is slidably arranged in the inner side of the guide groove 611, and the return spring 632 is fixed on the side of the locking cylinder 631 away from the clockwork spring 51.

[0052] When the reset spring 632 is in the original length state, the locking cylinder 631 is located at the end of the guide groove 611, and the side wall of the locking cylinder 631 is in close contact with the clockwork spring 51, so that the clockwork spring 51 is locked, and when the side plate 21 at the front end face of the storage box 2 is reversely turned forward, the connecting rope 64 is pulled out, and the locking cylinder 631 is slid along the guide groove 611 away from the clockwork spring 51, and the reset spring 632 is compressed, so that the locking cylinder 631 is separated from the clockwork spring 51, thereby releasing the locking state, and the clockwork spring 51 is conveniently pulled out, and when the storage cabinet 1 is transported, the storage cabinet 1 is inclined, the fixing cylinder 53 is downwardly arranged, and the fixing cylinder 53 is pulled out downwardly under the action of gravity, and the locking structure 63 is used for limiting the fixing cylinder 53, so that the fixing cylinder 53 is prevented from being pulled out in the transportation process, and the stability of the position of the clockwork spring 51 is improved.

[0053] Please refer to Figure 3 and Figure 4 The end of the connecting rope 64 close to the limiting hole 211 is fixed with a limiting block 641, and the length of the limiting block 641 is greater than the length of the limiting hole 211.

[0054] The limiting block 641 is obliquely arranged and is blocked on the outer wall of the side plate 21 on the upper side of the storage box 2 corresponding to the limiting assembly 6 through the limiting hole 211, so that when the side plate 21 on the storage box 2 is pulled out, the product can be conveniently taken out, and the corresponding locking structure 63 can be unlocked by the connecting rope 64, so that the corresponding display card can also be unfolded outwardly, and the product and the display card corresponding to the product can be displayed together without secondary unfolding after storage.

[0055] When the storage box 2 needs to be transversely unfolded, the limiting block 641 can be tilted again, so that the limiting block 641 is removed from the limiting hole 211, thereby facilitating disassembly and preventing affecting the transverse unfolding of the storage box 2.

[0056] The portable innovation and entrepreneurship guidance display card storage device is further described.

[0057] When storage is performed, the staff rotates the storage box 2 inwardly along the connection with the bottom face, the plurality of side plates 21 are mutually adsorbed to form a three-dimensional shape through the magnetic assembly 22 on the side wall, the staff can put the products into different storage boxes 2 respectively, then rotates the plurality of storage boxes 2 along the connecting rod 3 and mutually stacks in the storage cabinet 1, and then inserts the two side edges of the baffle 4 along the inner wall of the sliding groove 102 until the bottom face of the baffle 4 is in contact with the bottom face of the storage cabinet 1.

[0058] When it is necessary to display the products, the top storage box 2 is dragged to move towards the side wall. At this time, due to the hinging of the plurality of storage boxes 2 through the connecting rods 3, the plurality of storage boxes 2 are arranged side by side from top to bottom. Compared with the plurality of separate storage boxes 2, the plurality of storage boxes 2 are conveniently and quickly arranged. At the same time, the side plates 21 of the plurality of storage boxes 2 are fixed through the magnetic components 22. In order to improve the viewing experience of customers, the plurality of side plates 21 can be unfolded outwardly to form a multi-level display platform.
