The push-pull plates are pushed to make the push-pull plates drive the fitting plates to engage with the fitting grooves opened on the side of the insert plates through the connecting rods, thereby connecting and fixing the bottom frame component with the middle frame. Similarly, the four sets of insert plates at the bottom of the top frame component are inserted downwards into the four sets of docking cavities at the top of the middle frame component. Then, the top frame component and the middle frame are quickly fixed through the four sets of connecting components, thereby completing the assembly of the shelf structure. The middle frame has several sets, so the height of the shelf structure can be adjusted according to its own needs. The final effect is that the mortise and tenon structure connection between the fitting plates and the fitting grooves greatly improves the stability of the shelf structure.

[0014] 2. By setting up a docking groove, magnetic strip one, and magnetic strip two, when the fitting plate is not connected to the docking groove, the fitting plate is located inside the storage groove opened on the inner wall of the front side of the docking cavity, and the push-pull plate is located outside the docking groove. When the fitting plate is fitted and connected to the docking groove, the push-pull plate is located inside the docking groove, and the two sets of magnetic strip one and the two sets of magnetic strip two are respectively attracted and fixed. Then, the push-pull plate is fixed inside the docking groove by magnetic fixation, that is, the connecting component is fixed. At this time, the push-pull plate is fitted and connected to the docking groove, making the surface of the support rod flat, which greatly improves the aesthetics. At the same time, the mortise and tenon structure connection method avoids damage to the shelf. Attached Figure Description

[0025] 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 one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 5 A shelf structure with mortise and tenon joints includes: a central shelf assembly 200 and a connecting assembly. The connecting assembly includes a push-pull plate 400 for pushing and pulling a fitting plate 430, and the central shelf assembly 200 includes four support rods for connecting the placement plate.

[0027] Each set of support rods has a recessed top forming an insertion port 203. Each set of support rods has an insertion plate 220 at the bottom for docking with the insertion port 203. A docking groove 201 is provided on the upper front of the support rod. A moving hole 202 is provided through the rear side of the docking groove 201. Connecting components are installed inside the docking groove 201 and the moving hole 202.

[0028] The top frame assembly 300 is located above the middle frame. The bottom structure of the top frame assembly 300 is the same as the bottom structure and specifications of the middle frame. The bottom frame assembly 100 is located below the middle frame. The top structure and specifications of the bottom frame assembly 100 are the same as the top structure and specifications of the middle frame assembly 200. The middle frame has several sets of the same specifications. Therefore, multiple sets of middle frames can be selected and used in combination according to one's own needs, thereby increasing the height of the shelf structure.

[0029] The top and bottom of the support rod are glued with rubber layers 210. The top rubber layer 210 has a through hole that matches the specifications of the insertion port 203. The bottom rubber layer 210 is sleeved on the top outside of the insertion plate 220. The rubber layer 210 can ensure that after the insertion plate 220 is connected to the insertion port 203, the top of the insertion plate 220 is flexibly connected to the top of the insertion port 203.

[0030] A docking cavity is provided below the insertion port 203, and the length, width and depth of the docking cavity match the length, width and height of the insertion plate 220.

[0031] A receiving groove is provided on the inner wall of the front side of the docking cavity, which is opposite to the position of the docking groove 201. The receiving groove and the docking groove 201 are connected through a moving hole 202.

[0032] The front of the connecting component is a push-pull plate 400, and the rear of the push-pull plate 400 is fixed to the fitting plate 430 by a connecting rod 420. The length and width of the connecting rod 420 match the length and width of the moving hole 202. The length of the connecting rod 420 is greater than the total depth of the storage groove, the moving hole 202 and the docking groove 201.

[0033] The length, width, and thickness of the mating plate 430 match the length, width, and depth of the mating groove 221. The mating groove 221 matches the specifications of the storage groove. By pushing the push-pull plate 400, the mating plate 430 can be driven to detach from the storage groove and insert into the mating groove 221 through the connecting rod 420. Thus, the insertion plate 220 is fixed in the mating cavity through the mortise and tenon connection between the mating plate 430 and the mating groove 221, thereby completing the fixing of the insertion plate 220.

[0034] Magnetic strips 440 are horizontally embedded in the upper and lower positions of the back of the push-pull plate 400, and magnetic strips 230 are embedded in the upper and lower positions of the rear side of the docking groove 201. The magnetic strips 230 and 440 are positioned opposite each other and have opposite poles. The front of the push-pull plate 400 has a notch 410 for easy pulling out. After the push-pull plate 400 is pushed backward, it fits into the docking groove 201, thus making the surface of the support rod flat and beautiful. The two types of magnetic strips 440 on the upper and lower positions of the rear side of the push-pull plate 400 are attracted and fixed to the two sets of magnetic strips 230 on the upper and lower positions of the rear side of the docking groove 201, thereby fixing the push plate inside the docking groove 201, and then fixing the fitting plate 430 inside the fitting groove 221.

[0035] Example 1: Please refer to Figures 1 to 5In actual installation, the top structure of the base frame assembly 100 is the same as the top structure of the middle frame assembly 200, and the bottom structure of the top frame assembly 300 is the same as the bottom structure of the middle frame. The middle frame includes four sets of support rods and a placement plate. The side of the placement plate is fixed to the inner side of the four sets of support rods. An insertion port 203 is provided at the top of the support rod, and a docking cavity is provided below the insertion port 203. A storage groove is provided on the inner wall of the front side of the docking cavity. A rubber layer 210 is provided at the top of the insertion port 203. 0 can avoid hard collisions during docking. The bottom of the support rod is provided with an insertion plate 220. A rubber layer 210 is sleeved on the upper outer side of the insertion plate 220. The front of the insertion plate 220 is provided with a fitting groove 221. The upper front of the support rod is provided with a docking groove 201. A moving hole 202 is provided between the rear side of the docking groove 201 and the storage groove. A connecting rod 420 is placed inside the moving hole 202. A push-pull plate 400 is provided on the front side of the connecting rod 420. A fitting plate 430 is provided on the rear side of the connecting rod 420.

[0036] During installation, first place the base frame assembly 100 on the ground with the four sets of insertion ports 203 on the top of the base frame assembly 100 facing upwards. Then, pick up a set of middle frame assemblies 200 and insert the four sets of insertion plates 220 at the bottom of the middle frame assembly 200 downwards into the four sets of insertion ports 203, and insert them downwards along the insertion ports 203 into the mating cavity. At this time, the rubber layer 210 on the outer side of the top of the insertion rod contacts and compresses the rubber layer 210 on the outer side of the insertion port 203 to prevent a hard contact between the top of the insertion plate 220 and the top of the insertion port 203. The contact causes external wear on the shelf structure. After insertion, the push-pull plate 400 on the front side of the docking slot 201 is located. The push-pull plate 400 is pushed backward so that the push-pull plate 400 drives the fitting plate 430 to detach from the inside of the storage slot and insert into the inside of the fitting slot 221 through the connecting rod 420. Thus, the insertion plate 220 is fixed in the docking cavity through the tenon and mortise structure between the fitting plate 430 and the fitting slot 221. The two sets of insertion plates 220 on the front and rear sides are fixed in sequence through the connecting components, thereby fixing the middle frame above the base frame assembly 100.

[0037] After the middle frame is fixed, there are two options. The middle frame has several sets of the same specifications. The first option is to directly pick up the top frame assembly 300 and insert the four sets of insertion plates 220 at the bottom of the top frame assembly 300 downwards into the four sets of insertion slots 203 at the top of the middle frame assembly 200. Then, it is connected and fixed by the four sets of connecting components. The second option is to increase the number of layers of the middle frame as needed, thereby increasing the overall height of the shelf structure. Therefore, no matter which option is chosen, the connection between the top frame assembly 300, the middle frame, and the bottom frame assembly 100 is the same. That is, the connection between the mating plate 430 and the mating groove 221, and the mortise and tenon structure between the insertion plate 220 and the mating cavity are used to connect and fix the bottom frame assembly 100, the middle frame, and the top frame assembly 300. The final effect is to greatly improve the connection stability of the shelf structure.

[0038] Example 2: Please refer to Figures 2 to 5 When the insertion plate 220 is not inserted into the insertion port 203, the fitting plate 430 is located inside the receiving groove on the inner wall of the front side of the mating cavity. Since the length of the connecting rod 420 is greater than the total depth of the mating groove 201, the moving hole 202, and the receiving groove, the push-pull plate 400 is located in front of the mating groove 201. Because the fitting plate 430 is inside the receiving groove, it can prevent the fitting plate 430 from obstructing the insertion of the insertion plate 220. When the insertion plate 220 is inserted into the mating cavity through the insertion port 203, the position of the fitting groove 221 is opposite to the position of the receiving groove, moving towards... Push the push-pull plate 400, so that the push-pull plate 400 drives the fitting plate 430 to detach from the storage groove through the connecting rod 420 and insert it into the fitting groove 221. At this time, the push-pull plate 400 is inserted into the docking groove 201, and the two magnetic strips 440 on the back of the push-pull plate 400 are attracted and fixed to the magnetic strips 230 at the upper and lower positions on the rear side of the docking groove 201, thereby fixing the push-pull plate 400 inside the docking groove 201. Then, through the tenon and mortise structure connection between the fitting plate 430 and the fitting groove 221, the insertion plate 220 is fixed inside the docking cavity.

[0039] When the push-pull plate 400 is inside the docking groove 201, the length, width and thickness of the push-pull plate 400 match the length, width and depth of the docking groove 201, thus making the surface of the support rod flat, greatly improving the appearance of the shelf structure. Compared with using screws for fixing, the mortise and tenon structure connection can effectively avoid damage to the appearance of the shelf structure. When disassembly is required, simply hold the slot 410 on the front of the push-pull plate 400 and pull the push-pull plate 400 outward to disengage the fitting plate 430 from the fitting groove 221.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
