[0048] Example 1

[0049] Please refer to Figures 1 to 3 The present application provides a modular frame 100, comprising a first frame body 10 and a second frame body 20 which are stacked and connected.

[0050] Specifically, the first frame 10 includes a top plate 11 and a plurality of first support members 12 extending vertically, the upper end of the first support member 12 is connected to the lower surface of the top plate 11, and the lower end of the first support member 12 is provided with a first plug-in port 12a and a first plug-in portion 12b. The second frame 20 includes a bottom plate 21 and a plurality of second support members 22 extending vertically, the lower end of the second support member 22 is connected to the upper surface of the bottom plate 21, the upper end of the second support member 22 is provided with a second plug-in port 22a adapted to the first plug-in portion 12b, and the upper end of the second support member 22 is also provided with a second plug-in portion 22b adapted to the first plug-in port 12a. When the first plug-in portion 12b is plugged into the first plug-in port 12a, and the second plug-in portion 22b is plugged into the second plug-in port 22a, the first frame 10 and the second frame 20 are connected to form a modular frame 100.

[0051] Exemplarily, the "plurality" mentioned above refers to two or more, which can be set according to actual needs. Specifically in this embodiment, four first support members 12 are provided, and the four first support members 12 are correspondingly connected to the four corners of the lower surface of the top plate 11. Similarly, four second support members 22 are also provided, and the four second support members 22 are correspondingly connected to the four corners of the upper surface of the bottom plate 21, and correspond one to one with the first support members 12.

[0052] In addition, the first support member 12 and the top plate 11 are an integral part, and the second support member 22 and the bottom plate 21 are an integral part. In other words, the first support member 12 and the top plate 11, and the second support member 22 and the bottom plate 21 can all be made by an integrated molding process, thereby ensuring the structural strength of the first frame 10 and the second frame 20, and ensuring that the first frame 10 and the second frame 20 will not break during the subsequent assembly process.

[0053] The modular frame 100 based on the above technical features is formed by connecting a plurality of first support members 12 on the lower surface of the top plate 11 to form a first frame 10, and setting a first plug interface 12a and a first plug portion 12b at the lower end of the first support member 12, and connecting a plurality of second support members 22 on the upper surface of the bottom plate 21 to form a second frame 20, and correspondingly setting a second plug interface 22a and a second plug portion 22b at the upper end of the second support member 22. When assembly is required, the first plug portion 12b on the first support member 12 is inserted into the second plug interface 22a on the second support member 22, and the second plug portion 22b on the second support member 22 is inserted into the first plug interface 12a, so that the first frame 10 and the second frame 20 can be stacked and formed, so as to assemble and form the modular frame 100, so that the modular frame 100 can be used to assemble and form a combined storage rack as needed. The modular frame 100 has a simple structure and is easy to disassemble and assemble. When it is not needed, it can be disassembled and laid flat, and it takes up little space for transportation.

[0054] Exemplarily, the top plate 11, the bottom plate 21, the first support member 12 and the second support member 22 can all be made of plastic material, which is beneficial to reduce production costs, but it should be noted that the manufactured top plate 11, the bottom plate 21, the first support member 12 and the second support member 22 should have sufficient compressive strength to avoid breakage during subsequent assembly.

[0055] Reference Figure 4 In a possible embodiment, the top plate 11 and the bottom plate 21 each include a plurality of plate bodies 30 connected in sequence, and each plate body 30 is provided with a docking portion 31 and an extension port 32 on both sides connected to the adjacent plate bodies 30, respectively, and the extension port 32 is used to connect to the interior of the plate body 30 so that the docking portion 31 extends into the interior of the plate body 30 for fixation.

[0056] In this embodiment, both the top plate 11 and the bottom plate 21 are formed by connecting a plurality of plate bodies 30 in sequence. In order to avoid too much elaboration, the following description is made by taking the bottom plate 21 as an example of being assembled from four plate bodies 30, as follows:

[0057] Reference Figure 5 Since each plate body 30 is provided with a docking portion 31 and an insertion opening 32 at both ends thereof for connecting with the adjacent plate bodies 30, when assembling, the first plate body and the second plate body among the four plate bodies 30 are connected first, that is, the docking portion 31 of the first plate body is inserted into the interior of the second plate body from the insertion opening 32 of the second plate body to realize the fixed connection between the first plate body and the second plate body, and then the insertion opening 32 of the third plate body is aligned with the docking portion 31 of the second plate body, and the third plate body is pushed toward the second plate body until the docking portion 31 of the second plate body is inserted into the interior of the third plate body from the insertion opening 32 of the third plate body, thereby completing the assembly of the first plate body, the second plate body and the third plate body, and finally the docking portion of the fourth plate body is aligned with the insertion opening of the first plate body and then inserted, so that the docking portion 31 of the fourth plate body is inserted into the first plate body, and then the fourth plate body is pushed so that its insertion opening is aligned with and inserted into the docking portion of the third plate body, and then the docking portion 31 of the third body is inserted into the fourth plate body, thereby completing the assembly of the entire bottom plate 21. In addition, it should be noted that the connection between the fourth plate body and the first plate body and the third plate body can also be achieved by first aligning the fourth plate body's extension port with the docking portion of the third plate body and inserting it, and then pushing the first plate body so that the docking portion of the fourth plate body is inserted into the first plate body to complete the assembly of the fourth plate body with the other three plate bodies.

[0058] Please refer to Figure 6 and Figure 7In a possible implementation, the lower surface of the docking portion 31 is provided with an opening 31a, an elastic arm 33 is provided in the opening 31a, a protrusion is formed at the front end of the elastic arm 33, and a bayonet 34 connected to the insertion opening 32 is provided on the lower surface of the plate body 30. When the docking portion 31 is inserted into the plate body 30 from the insertion opening 32, the protrusion is inserted into the bayonet 34, so that the adjacent plate bodies 30 are fixed.

[0059] Illustratively, in the process of extending the docking portion 31 from the insertion opening 32 into the interior of the plate body 30, the elastic arm 33 will abut against the inner wall of the plate body 30 to be in a compressed state. Thereafter, as the docking portion 31 continues to extend into the interior of the plate body 30 and the elastic arm 33 moves to the position of the bayonet 34, the protrusion of the elastic arm 33 disengages from the abutment against the inner wall of the plate body 30 and falls into the bayonet 34, so that the docking portion 31 can no longer be pushed in, thereby fixing the adjacent plate bodies 30; when disassembly is required, the elastic arm 33 is pushed inward to disengage the protrusion of the elastic arm 33 from the bayonet 34, and then pulled outward to achieve disassembly of the two plate bodies 30. The structure is simple, disassembly and assembly are convenient, no additional fasteners are required for fixing, and the appearance is more beautiful.

[0060] Please refer to Figure 7 In a possible implementation, a plurality of reinforcing strips 35 are provided at intervals inside the plate body 30, and the distance between the end of the reinforcing strip 35 close to the insertion opening 32 and the extension opening is greater than the width of the docking portion 31. In this way, the compressive strength of the plate body 30 can be enhanced to prevent the plate body 30 from being deformed after being squeezed by the outside. Specifically, the reinforcing strip 35 can be connected to the inside of the plate body 30 by an integrated molding process, thereby ensuring the structural strength of the reinforcing strip 35 and the plate body 30.

[0061] Please refer to Figure 7 In a possible implementation, the docking portion 31 and the side of the plate body 30 form an inner cavity, and the inner cavity has a plurality of reinforcing blocks 36 distributed along the length direction of the docking portion 31. In this way, the strength of the docking portion 31 can be enhanced to ensure that it will not be broken due to extrusion during the insertion process into the plate body 30.

[0062] In a possible implementation, limiting blocks are provided on the surfaces of the first plug-in portion 12b and the second plug-in portion 22b, limiting plates are provided at the bottoms of the first plug-in interface 12a and the second plug-in interface 22a, and the limiting plates are provided with limiting openings matched with the limiting blocks.

[0063] For example, when the first frame 10 and the second frame 20 are connected, the first plug-in portion 12b is inserted into the first plug-in port 12a, and as the first plug-in portion 12b is continuously extended, the stop block abuts against the inner wall of the stop opening, so that the stop block is in a compressed state, until the stop block is fully extended into the first plug-in port 12a, the stop block passes through the stop opening, and is abutted by the lower surface of the stop plate, so that the first plug-in portion 12b is firmly fixed in the first plug-in port 12a, and the first plug-in portion 12b is prevented from being separated from the first plug-in port 12a. Since the method of inserting the second plug-in portion 22b into the second plug-in port 22a is the same as the method of inserting the first plug-in portion 12b into the first plug-in port 12a, the details can be referred to the above description, and no further description is given.

[0064] Example 2

[0065] Please refer to Figures 8 to 10 The embodiment of the present application also provides a combined storage rack, including multiple docking pieces 200 and multiple modular frames 100, wherein slots 300 are provided on the upper surface of the top plate 11 and the lower surface of the bottom plate 21 of the modular frame 100, and one end of the docking piece 200 is inserted into the slot 300 of the top plate 11 of one modular frame 100, and the other end is inserted into the slot 300 at the bottom of another modular frame 100, so as to connect the multiple modular frames 100 in the longitudinal direction to form a combined storage rack.

[0066] In the present embodiment, the first frame body 10 and the second frame body 20 are first assembled to form a plurality of modular frames 100, and then slots 300 are provided on the top plate 11 and the bottom of each modular frame 100. When the combined storage rack needs to be assembled, one end of the docking piece 200 is first inserted into the slot 300 of the bottom plate of one modular frame 100, and then the slot 300 of the top plate 11 of another modular frame 100 is aligned with the other end of the docking piece 200, and then the modular frame 100 is pushed toward the docking piece 200 so that the other end of the docking piece 200 is inserted into the slot 300 of the top plate 11 of the other modular frame 100, thereby completing the assembly of the two modular frames 100 in the longitudinal direction, and the above-mentioned actions are repeated in sequence until the assembly of the entire combined storage rack is completed. The structure is simple, the assembly is convenient, and the required number of layers can be assembled.

[0067] Please refer to Fig.10 and Fig.11In a possible implementation, the middle part of the connector is provided with a limit strip 200a distributed along its circumference, and the groove top and the top or bottom surface of the slot 300 are formed with a stepped groove. When the connector is inserted into the slot 300, the limit strip 200a abuts against the stepped groove. In this way, after one end of the connector is inserted into the slot 300, the limit strip 200a abuts against the stepped groove to ensure that the connector does not completely fall into the slot 300, so that another modular frame 100 can be connected later.

[0068] Example 3

[0069] Please refer to Fig.12 The embodiment of the present application further provides a combined storage rack, including a plurality of locking members 500 and a plurality of modular frames 100 as described above, wherein the plurality of modular frames 100 are sequentially connected in a transverse direction through the locking members 500 to form a combined storage rack.

[0070] In this embodiment, the first frame 10 and the second frame 20 are first assembled to form a plurality of modular frames 100, and then the plurality of modular frames 100 are arranged in sequence in the horizontal direction, and then the locking member 500 is used to lock the butt edges of the adjacent modular frames 100 until the assembly of the entire combined storage rack is completed. The structure is simple, the assembly is convenient, and the required number of layers can be assembled.

[0071] Please refer to Fig.13 and Fig.14 In a possible implementation, the inner sides of the top plate 11 and the bottom plate 21 are both provided with abutment strips 600 , the bottom surface of the locking member 500 is provided with an opening connected to the interior thereof, and the inner wall of the opening is provided with a convex strip 500 a matched with the abutment strip 600 .

[0072] Exemplarily, by providing abutment strips 600 on the inner sides of the top plate 11 and the bottom plate 21, after the adjacent modular frames 100 are arranged, the opening of the locking member 500 is aligned with the two inner sides close to the top plate 11 and the bottom plate 21, and is inserted into the interior of the locking member 500. At this time, the convex strip 500a is in abutment with the abutment strip 600, thereby ensuring that the adjacent modular frames 100 are firmly connected. When disassembly is required, the locking member 500 only needs to be pulled upwards to disengage the adjacent modular frames 100 from the lock, so that quick disassembly can be achieved. The structure is simple and assembly and disassembly are convenient.

[0073] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
