[0020] In this embodiment, the combination rack 100 can be installed on an external fixing rack by the cooperation of the first fixing member 300 and the first installation position 110. The combination rack 100 can also be assembled and installed on another combination rack 100 by the second fixing member 400, the first installation position 110 and the second installation position 120, so that the combination rack 100 can be infinitely assembled in theory and can be detachably installed, which is convenient for users to purchase a sufficient number of combination racks 100 according to actual conditions, or when the demand for storing items is reduced, some combination racks 100 can be detached to save space, which is very convenient for home use. At the same time, it can also be placed on both sides of the desk in school to place pens and books, so that the space on the desktop is larger and the learning efficiency is higher.

[0021] Specifically, the first fixing member 300 connects the combination frame 100 and the external fixing frame, the second fixing member 400 connects the two combination frames 100, the installation position of the first fixing member 300 is the first installation position 110 of the external fixing frame and the corresponding combination frame 100, and the installation position of the second fixing member 400 is the first installation position 110 and the second installation position 120 of two adjacent combination frames 100.

[0022] Specifically, the spacing spaces in the combination rack 100 may be arranged the same or differently. For example, in order to place vertical strip-shaped items such as pens, a plurality of partition boards may be arranged in the combination rack 100. In order to place books, the combination rack 100 may be arranged in a long trumpet-shaped enlarged shape from bottom to top. The inner enclosure of the combination rack 100 is vertical, and the outer enclosure is inclined outward. After the books are placed, they are inclined outward for easy taking.

[0023] In a preferred embodiment, each assembly rack 100 can be connected to an external fixing rack via a first fixing member 300 to improve the installation strength, and can also be connected to an adjacent assembly rack 100 via a second fixing member 400 .

[0024] In one embodiment, one first fixing member 300 is provided to connect the external fixing frame and the combined frame 100, and a plurality of the combined frames 100 are hung on the external fixing frame as a whole;

[0025] The first fixing member 300 includes a "C"-shaped or "匚"-shaped fixing piece with an opening. A bolt fastener is provided on the fixing piece. A first clip with an upward opening is provided on the side of the fixing piece away from the opening. The first clip is engaged in the first mounting position 110, and the combined frame 100 is hung on the first fixing member 300 by using the gravity of the combined frame 100.

[0026] In this embodiment, only one combined frame 100 is connected to the external fixing frame through the first fixing member 300, and the other combined frames 100 are all hung on this combined frame 100 indirectly or directly. When in use, not too many mounting positions need to be set on the external fixing frame, and the expandable clip can be applied to more scenarios, such as a desk, etc.;

[0027] Specifically, the first fixing member 300 is set to be "C"-shaped or "匚"-shaped and is provided with a bolt fastener for cooperation, which can be clamped at positions such as the extended table edge. The first clip has an upward opening, and the first mounting position 110 can be an opening. The first clip can hook the first mounting position 110, thereby realizing the installation of the combined frame 100;

[0028] The first clip and the first mounting position 110 can also be in a snap connection manner.

[0029] In one embodiment, a plurality of the combined frames 100 are arranged and installed in sequence from top to bottom. The top combined frame 100 is connected to the external fixing frame through the first fixing member 300. The second fixing member 400 includes a fixing piece, and a second clip and a third clip are provided on the fixing piece. The second clip is engaged and installed in the second mounting position 120 of the upper combined frame 100 by using the gravity of the fixing piece, and the third clip is engaged and installed in the first mounting position 110 of the combined frame 100 by using the gravity of the combined frame 100.

[0030] In this embodiment, the connections between the combined frames 100 are all one-to-one, that is, the adjacent combined frames 100 are all in an up-and-down relationship. The top combined frame 100 serves as a bridge connecting the external fixing frame, and the second fixing member 400 serves as a bridge connecting the adjacent upper and lower combined frames 100;

[0031] Specifically, the second clip and the third clip are respectively matched and installed with the adjacent upper second mounting position 120 and the adjacent lower first mounting position 110 to connect the adjacent upper and lower combined frames 100.

[0032] In one embodiment, the opening of the second clip is downward, and the opening of the third clip is upward.

[0033] In this embodiment, both the second clip and the third clip hook the second mounting position 120 and the first mounting position 110.

[0034] Specifically, the second mounting position 120 and the first mounting position 110 can be openings.

[0035] In one embodiment, the opening of the second clip is downward, and the third clip is in a "π" shape.

[0036] In this embodiment, compared with the previous embodiment, the shape of the third clip is set to a "π" shape. During installation, the third clip is placed obliquely. After one side is inserted into the first mounting position 110, the other side is then inserted into the first mounting position 110 to achieve a yielding installation. The third clip installed in this way has a more stable structure, will not have large晃动, and is difficult to disassemble, avoiding the combination rack 100 from easily coming out when there are not enough items stored in the combination rack 100.

[0037] In one embodiment, the second clip and the third clip are respectively arranged on both sides of the fixing piece.

[0038] In this embodiment, by arranging the second clip and the third clip on both sides of the fixing piece, when installing, the fixing piece is installed on the outside of the previous combination rack 100 and the inside of the next combination rack 100. Considering that most of the combination racks 100 are used to place books for students, such a setting will make each next combination rack 100 deviate inward a little more than the previous combination rack 100, avoiding blocking the classroom aisle.

[0039] In one embodiment, the first clip is in a "π" shape.

[0040] In this embodiment, by making the first clip in a "π" shape, the structure is more stable, will not have large晃动, and is difficult to disassemble, avoiding the combination rack 100 from easily coming out when there are not enough items stored in the combination rack 100.

[0041] In one embodiment, the first mounting position 110 is in a "convex" shape with a smaller upper width than the lower width, and the upper and lower connections are connected by an inclined side. The first fixing member 300 or the second fixing member 400 is clamped to the upper part of the first mounting position 110 through a "π" shaped structure.

[0042] In this embodiment, by setting the first installation position 110 to be "convex", the first fixing member 300 or the second fixing member 400 is easier to install and can be inserted from the wider hole at the bottom. After installing the combined frame 100 and placing heavy objects therein, the combined frame 100 will move downward relatively, and the connection between the first fixing member 300 or the second fixing member 400 will become tighter and tighter. When reaching the top with a smaller width, the "convex"-shaped clip will cooperate with the top with a smaller distance between the two sides, and the fitting area between the clip and the combined frame 100 will be larger and more stable.

[0043] In one embodiment, the assembly frame 100 at the top is provided with a plurality of partition plates, and the assembly frame 100 is configured to be a speaker amplification shape from bottom to top.

[0044] In one embodiment, a hanging box 200 is also included;

[0045] A third installation position is provided on one side of the assembly frame 100 , and the hanging box 200 is installed in the third installation position through a third fixing member to be hung on the assembly frame 100 .

[0046] In this embodiment, the storage space is further increased by providing the hanging box 200.

[0047] The third fixing member and the third installation position may correspond to the structures of the first fixing member 300 , the second fixing member 400 , the first installation position 110 , and the second installation position 120 , respectively.

[0048] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
