Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Please see Figure 1-5 This utility model embodiment provides a technical solution to achieve this: it includes a leg 1, casters 2, a lower frame 3, an upper frame 4, a self-locking hinge 5, and a locking mechanism 6. The leg 1 is arranged in a left-right structure. The casters 2 are evenly arranged at the bottom of each leg 1. The lower frame 3 is arranged between two legs 1. The upper frame 4 is arranged at the top of the lower frame 3. The self-locking hinge 5 is arranged in a left-right structure on the back between the lower frame 3 and the upper frame 4. The locking mechanism 6 is arranged on the front between the lower frame 3 and the upper frame 4.

[0029] The locking mechanism 6 includes a lock frame 61, a post hole 62, a pull plate 63, a connecting post 64, a pull head 65, a spring 66, a bolt 67, and a cooperating locking mechanism 68. The lock frames 61 are arranged in a group, with each group of lock frames 61 corresponding to each self-locking hinge 5. The lock frames 61 are located at the bottom of the upper frame 4 and the top of the lower frame 3. The post hole 62 is located at the center of the front end of each lock frame 61. The pull plate 63 is located inside each lock frame 61. The connecting post 64 is located at the front end of the pull plate 63 and extends forward through the post hole 62. The pull head 65 is located at the front end of each connecting post 64. The springs 66 are evenly distributed at the front end of the pull plate 63 and connected to the lock frame 61. The springs 66 are also located on the left and right sides of the connecting post 64. The bolt 67 is arranged in a left-right structure at the rear end of each pull plate 63. The cooperating locking mechanism 68 is located on the back of each pull plate 63.

[0030] In detail, the locking frame 61 has a U-shaped structure. The height of the locking frame 61 is less than the height of the top of the lower frame 3 and the height of the bottom of the upper frame 4. The top of the upper locking frame 61 and the top of the bottom of the upper frame 4 are on the same straight line. The bottom of the lower locking frame 61 and the bottom of the top of the lower frame 3 are on the same straight line. The pull plate 63 has a cuboid structure. The connecting column 64, the pull head 65 and the plug 67 are all cylindrical structures. The pull plate 63, the connecting column 64, the pull head 65 and the plug 67 are integrally formed.

[0031] The locking mechanism 68 includes an upper plate 681, a lower plate 682, a lower groove 683, an upper groove 684, a plate insertion hole 685, and a groove insertion hole 686. The upper plate 681 is arranged in a left-right structure at the bottom of the upper frame 4. The lower plate 682 is arranged in a left-right structure and is staggered with the two upper plates 681 at the top of the lower frame 3. The lower groove 683 is embedded in the lower frame 3 to the right of each lower plate 682, corresponding to the position of each upper plate 681. The upper groove 684 is embedded in the upper frame 4 to the left of each upper plate 681, corresponding to the position of each lower plate 682. The plate insertion hole 685 is centrally located through the interior of each upper plate 681 and the interior of each lower plate 682. The groove insertion hole 686 is centrally located through the interior of each lower groove 683 and the interior of each upper groove 684.

[0032] Both the upper plate 681 and the lower plate 682 are rectangular parallelepiped structures. The front end of the upper plate 681 is on the same plane as the front end of the upper frame 4, and the front end of the lower plate 682 is on the same plane as the front end of the lower frame 3. When the bottom of the upper frame 4 contacts the top of the lower frame 3, each plate insertion hole 685 and the adjacent slot insertion hole 686 are on the same straight line.

[0033] The upper and lower halves of the self-locking hinge 5 are evenly provided with receiving holes 51. Each slot insertion hole 686 can be aligned with the adjacent receiving hole 51. The position of the bolt 67 of the upper pull plate 63 corresponds to the position of the slot insertion hole 686 inside each upper upper groove 684. The position of the bolt 67 of the lower pull plate 63 corresponds to the position of the slot insertion hole 686 inside each lower lower groove 683.

[0034] Example 2:

[0035] like Figure 6 As shown: This solution can also be designed as a left-right folding structure, with the upper frame 4 and the lower frame 3 being an integrated structure. Starting from the leftmost frame, from left to right, there are pairs of self-locking hinges 5 at the front end between the leftmost frame and the second frame. There are pairs of self-locking hinges 5 at the rear end between the second and third frames. Then, there are pairs of self-locking hinges 5 at the front end between the third and fourth frames. This arrangement is repeated in an alternating manner, so that by folding between each pair of adjacent frames, multiple frames can be folded into several horizontal layers, which can greatly reduce the space occupied and is also very convenient to unfold.

[0036] Solution Analysis:

[0037] Distribute stress and extend component life:

[0038] In existing technology, the self-locking hinge 5 bears the bending force of the frame alone, which is prone to accelerated damage. This solution uses a locking mechanism 6 in conjunction with the self-locking hinge 5. The bolt 67 of the locking mechanism 6 is inserted into the receiving hole 51, and the upper connecting plate 681 and the lower connecting plate 682 are engaged with the corresponding slots. This distributes the bending force of the frame to the locking mechanism 6 and the self-locking hinge 5, avoiding excessive stress on a single structure, reducing wear on the connecting structure caused by concentrated stress, extending the service life of components, reducing the replacement frequency, and reducing material consumption.

[0039] Enhance connection stability:

[0040] In the locking mechanism 6, the spring 66 pulls down the plate 63, which in turn drives the bolt 67 to insert into the plate insertion hole 685 and the slot insertion hole 686, and extends to the receiving hole 51 of the self-locking hinge 5. The upper plate 681 and the lower plate 682 are interlocked, and the multi-part connection makes the connection between the upper frame 4 and the lower frame 3 more stable, preventing wobbling and misalignment when folded and combined, thus improving the overall structural stability of the display rack and ensuring the shape of the display rack during use.

[0041] Ease of use:

[0042] During operation, pulling up the pull head 65 allows the bolt to be disengaged. Utilizing the length characteristic of the locking frame 61, when the upper frame 4 is folded up, the upper connecting plate 681 and the lower connecting plate 682 can rotate freely into their corresponding slots. After releasing the handle, the spring 66 automatically resets the bolt 67 to complete the locking process. The operation is simple, requiring no complicated tools or steps, making it easy for users to fold and combine the display rack, thus improving the user experience.

[0043] Working principle:

[0044] Each upper plate 681 and lower plate 682 are staggered and respectively engaged with the lower groove 683 and upper groove 684. The upper plate 681 and upper frame 4 are integrally formed, and the lower plate 682 and lower frame 3 are integrally formed. When the upper frame 4 is flipped up, the pull heads 65 of the upper and lower locking frames 61 are pulled up, causing the pull plate 63 to drive the bolt 67 to be pulled out of each plate insertion hole 685. Since the length of the left and right sides of the locking frame 61 is greater than the thickness of the lower frame 3 or the upper frame 4, the plate insertion hole 685 can rotate freely into the lower groove 683 and upper groove 684 during the process of pulling up the pull head 65 and flipping up the upper frame 4. Finally, when released, under the force of the spring 66, the pull plate 63 carries the bolt 67 into the corresponding plate insertion hole 685 and groove insertion hole 686 and continues to extend into the inside of the receiving hole 51, further strengthening the fixing effect.

[0045] Technical effects of implementing this solution:

[0046] This solution utilizes a locking mechanism and self-locking hinges in synergy to: 1) distribute stress, reducing the burden on individual structures, extending component lifespan, and reducing material consumption; 2) enhance the stability of the frame structure through multi-part connections; and 3) simplify the operation process for user convenience. By optimizing structural durability, stability, and user experience from multiple dimensions, this solution effectively addresses the shortcomings of existing technologies and improves the practicality and reliability of the combined folding connection structure of the screen grid display rack.

[0047] The components of this utility model are: 1-leg; 2-caster wheel; 3-lower frame; 4-upper frame; 5-self-locking hinge; 51-receiving hole; 6-locking mechanism; 61-locking frame; 62-column hole; 63-pull plate; 64-connecting column; 65-pull head; 66-spring; 67-bolt; 68-fitting locking mechanism; 681-upper plate; 682-lower plate; 683-lower groove; 684-upper groove; 685-plate insertion hole; 686-groove insertion hole. These components are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that the existing connection structure uses a self-locking hinge that can be adjusted at will and locked by the spring force. However, this structure bears the bending force between the entire upper half of the frame and the entire lower half of the frame alone. With long-term use, it is easy to accelerate the service life of the connection structure and promote its frequent replacement, increasing the consumption of materials. This invention optimizes structural durability, stability, and user experience from multiple dimensions, effectively addressing the shortcomings of existing technologies and improving the practicality and reliability of the combined folding connection structure of the screen grid display rack.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
