[0041] Example 1

[0042] like Figures 1-5 As shown, a furniture cabinet with an internally hidden connection structure includes a cabinet 1, which is a conventional furniture cabinet 1 disclosed in the prior art. Its main structure includes the main body of the cabinet 1, cabinet doors installed on the main body of the cabinet 1, and several shelves for placing items.

[0043] Specifically, the shelf includes side panels 3 spaced apart on both sides and several shelf boards 21 installed between the side panels 3. To achieve a concealed installation method connecting the shelf boards 21 to the side panels 3, firstly to avoid items being scratched or damaged by the installation structure, and secondly to increase the installation stability of the shelf boards 21 and prevent them from loosening after placing heavy objects, the following improvements are made:

[0044] The hidden connection structure comprises an inner sinking strip 22 (metal material) mounted on the side panel 3. Specifically, an inner sinking groove 31 is formed on the side panel 3, and the inner sinking strip 22 is positioned in the inner sinking groove 31. The side wall of the inner sinking strip 22 is flush with the side panel 3.

[0045] A plurality of female sleeves 231 (also metal material, cylindrical shape) are mounted on the inner sinking strip 22. Specifically, a plurality of threaded through holes for screwing the female sleeves 231 are formed on the inner sinking strip 22 (an outer thread structure is formed on the outer side wall of the female sleeve 231).

[0046] Correspondingly, a plurality of mounting grooves 311 are formed in the inner sinking groove 31 on the side panel 3, and the female sleeves 231 are mounted in the mounting grooves 311 (in order to increase the mounting stability of the female sleeves 231, the mounting grooves are cylindrical in shape). The female sleeves 231 are mounted in the mounting grooves 311 by interference fit (during operation, the stability of the inner sinking strip 22 and the female sleeves 231 is increased by interference fit).

[0047] A plurality of sub-clamping column structures 23 cooperating with the female sleeves 231 are mounted on the above-mentioned storage plate 21. The sub-clamping column structure 23 comprises a clamping column 232 clamped in the female sleeve 231, and the clamping column 232 is slidingly connected with a sleeve seat 234.

[0048] Specifically, the clamping column 232 and the sleeve seat 234 are slidingly connected by a spring structure. Specifically, the sliding mode is as follows: the spring structure comprises an internal sliding rod 235 fixedly mounted in the sleeve seat 234, and the internal sliding rod 235 is slidingly connected to the clamping column 232. An internal spring 236 is sleeved on the clamping column 232, and the two ends of the internal spring 236 are fixedly connected to the sleeve seat 234 and the clamping column 232, respectively.

[0049] During operation, the spring structure is slidingly expanded and contracted. By sliding expansion and contraction, the clamping column 232 is elastically retracted into the sleeve seat 234 during operation, and the clamping column 232 is reset and locked into the female sleeve 231 under the elastic restoring force of the internal spring 236.

[0050] During operation, after aligning the side of the storage plate 21 to be slightly inclined to the female sleeve 231 and retracted to a certain depth, the storage plate 21 is pressed down, and the clamping column 232 on the other side is retracted into the sleeve seat 234 during the pressing process and is clamped into the female sleeve 231. In this way, the storage plate 21 is elastically locked and hidden during operation. Alternatively, the clamping column 232 on the other side is pressed by a tool (such as a tool pressing strip), and then the tool is withdrawn until the clamping column 232 is clamped into the female sleeve 231.

[0051] In order to further prevent the shelf 21 from loosening during use, the above-mentioned card post 232 is integrally formed with several circumferentially distributed card protrusions 233 (the length is less than the length of the card post 232 and the shape is strip-shaped), and the inner side wall of the female card sleeve 231 is provided with several card grooves 2311 that cooperate with the card protrusions 233.

[0052] When the locking pin 232 is locked into the female locking sleeve 231, the locking protrusion 233 on the locking pin 232 is locked into the locking groove 2311. During this process, the structure of the locking protrusion 233 and the locking groove 2311 further avoids the technical defects of the shelf 21 being loose or shaking due to the loosening between the locking pin 232 and the female locking sleeve 231.

[0053] Similarly, the aforementioned outer sleeve 234 is fixedly installed inside the shelf 21. Specifically, the shelf 21 has several mounting slots 211 for mounting the outer sleeve 234, and the outer sleeve 234 is interference-fitted into the mounting slots 211. This interference fit further increases the stability of the shelf 21 and avoids the defect that the outer sleeve 234, which is slidably engaged with the locking post 232, is prone to loosening during operation.

[0054] Example 2

[0055] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 1, the two ends of the shelf 21 are respectively locked to the two ends of the inner recessed strip 22 by locking post structures 4. The locking post structures 4 further lock the shelf 21 to the inner recessed strip 22 and the side panel 3 from both ends, thereby further increasing the stability of the shelf 21.

[0056] Specifically, the locking post structure 4 includes an elastic locking post 42 elastically mounted on the shelf 21. The inner countersunk strip 22 has a locking groove 41 that mates with the elastic locking post 42. The shelf 21 has an inner sliding groove that mates with the elastic locking post 42. A short spring 43 is fixedly connected to the inner end of the elastic locking post 42, and the short spring 43 is fixedly connected within the inner sliding groove. The outer end of the elastic locking post 42 is integrally formed with a curved locking part; the shape of the locking groove 41 corresponds to the shape of the curved locking part.

[0057] During the installation of the shelf 21 in the manner described above, the curved locking part on the elastic locking pin 42 is engaged into the locking groove 41, completing the installation of the entire panel. In this process, the shelf 21 is fully secured and installed in this way, making it less prone to loosening or shaking during use, thus greatly increasing the stability of the shelf 21 during use.

[0058] Of course, the above description is not a limitation of the utility model, the utility model is also not limited to the above examples, the changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the utility model should also belong to the protection scope of the utility model.
