[0028] and / or the crests and troughs of the connecting section are parallel.

[0029] In view of the above technical features, the present invention has the following beneficial effects:

[0030] 1. The inner wall of the storage space of the storage box of the present invention is provided with a connecting section having a wavy cross-section. This connecting section is used to cooperate with the connecting part of the connecting piece with storage function to achieve the installation positioning, rotation, and post-rotation positioning of the connecting piece. The combination between this wavy connecting section and the connecting piece is more flexible, convenient to use, and the unit structure of the wavy connecting section is simple and compact. The single-step length (i.e., the distance between adjacent wave crests or the distance between adjacent wave troughs) can be adjusted. As the size of the storage box and / or the middle frame changes, the step length can be large or small, without being restricted by specific dimensions. As long as the step length matches the shape and size of the protruding dots and / or protruding horizontal bars and can help the connecting piece achieve the installation positioning, rotation, and post-rotation positioning on the connecting section, the position adjustment of the connecting piece on the connecting section is flexible (i.e., high flexibility), which greatly improves the space utilization rate inside the box body. The connection method between the connecting piece (such as a card strip) and the wavy connecting section is diverse, and the positioning and fixing performance are reliable, and it can be installed, positioned, rotated, and post-rotated quickly and flexibly.

[0031] 2. Various card strips (i.e., connecting pieces) can be set in the storage space of the storage box, such as the first card strip, the second card strip, and the third card strip, which can be used alone, or multiple can be selected, or other card strips that meet the requirements of items or tools. As long as the connecting part of the card strip and the connecting section achieve the installation positioning and / or rotation and / or post-rotation positioning, the storage space inside the storage box can be utilized more efficiently, and the utilization rate of the storage space can be improved. In addition, the positions of the connecting section and the card strip can also be adjusted at any time according to the actual situation, improving the flexibility and convenience of the card strip and the box body during use.

[0032] 2. The middle frame of the present invention can exist as an independent product, which is convenient for users to replace the middle frame at any time, saving costs for users. The structure of the middle frame is simple. The inner wall of the middle frame is provided with a connecting section having a wavy cross-section. This connecting section is used to cooperate with the connecting part of the connecting piece with storage function to achieve the installation positioning, rotation, and post-rotation positioning of the connecting piece. The combination between this wavy connecting section and the connecting piece is more flexible, convenient to use, and the space utilization rate inside the box body is high. The connection method between the connecting piece (such as a card strip) and the wavy connecting section is diverse, and it can be installed, positioned, rotated, and post-rotated.

[0033] 3. The middle frame of the present invention is a modular product, which can be conveniently produced in a standardized manner. The structure of the middle frame itself is simple and reliable, without complex structures, and the mold development process is simple and the process flow is short, thereby achieving lower production costs. When the middle frame is a modular product, it can simultaneously match multiple storage outer box products of different specifications and appearances with the same process flow, realize the co-linear flexible production of products of various specifications and appearances, and improve production efficiency. For example, the middle frame and connecting parts (card strips), articles or tools and other products can be pre-assembled independently as complete module semi-finished products, and can be quickly assembled with storage boxes of different specifications and appearances as needed, reducing the damage of appearance parts during the production process, and can be quickly and non-destructively replaced and distributed, generating finished products of various specifications and appearances in a shorter production cycle, realizing agile production and greatly shortening the production cycle. Compared with traditional storage boxes, it is necessary to produce storage boxes first, and then assemble articles or tools and other products in the storage boxes to form a complete and saleable product, which has poor flexibility and is difficult to replace and distribute. Therefore, the use of the middle frame can effectively improve the production efficiency of storage boxes with items or tools inside. The production process is more flexible, the process is shorter, and the production is more convenient, which is a great benefit for the manufacturer. It can effectively reduce production costs, allowing the manufacturer to provide more cost-effective storage boxes (with items or tools inside).

[0034] Of course, for consumers (i.e. users), the simpler structural construction makes the assembly of the middle frame and its connectors easier and more intuitive. The concise but multifunctional connectors can meet the personalized storage needs of each user, which is more flexible and brings a better user experience. The assembly objects of traditional storage boxes are specific, that is, traditional storage is mostly subject to the fixed design of the manufacturer, limited to items or tools of specific shapes and / or models. Once the items or tools of specific shapes and / or models are lost, the storage function is partially or completely lost, resulting in waste of resources. The storage box of the present invention can be used with the help of the middle frame and flexible and diverse connecting accessories. Users can increase, reduce, and change the assembly method locally according to the needs of different periods, so as to achieve effective storage of items or tools of various shapes and / or models without having to repurchase the entire system, reducing capital expenditure and resource waste, achieving a win-win situation, and being more environmentally friendly.

[0035] Therefore, a storage box with a middle frame design is a win-win solution for both manufacturers and consumers.

[0036] 4. In the present invention, whether it is a storage box with a connecting section with a wavy cross section or a middle frame with a connecting section with a wavy cross section:

[0037] First of all, the design of this wavy connecting section is a connecting mechanism design with simple structure, small single volume (more material saving), and space-saving storage. The connection between the connecting section and the connecting part of the connecting piece can be quickly installed and disassembled, and the connecting piece can be rotated and / or positioned after rotation, which is convenient for users to install or pick up items or tools, and is simple and convenient to use;

[0038] Secondly, this design also has strong inclusiveness and compatibility, and there are more possibilities for flexibility in the storage space;

[0039] Thirdly, the combination between the storage box and the connecting piece (such as the card strip) is more flexible, making the utilization rate of the storage space in the storage box higher;

[0040] Finally, the storage box can be recycled and can also be applicable to unspecified objects (items or tools of different shapes or models), saving production raw materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] The present invention will be further described below in conjunction with the detailed implementation manners. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0078] Refer to Figures 1 to 16 , in the specific embodiment 1, this embodiment 1 provides a storage box 1. The inner wall of the storage space of the storage box 1 is provided with a connecting section 3 with a wavy cross-section, and this connecting section 3 is used to cooperate with the connecting part of the connector with storage function to realize the installation positioning and / or rotation and / or post-rotation positioning of the connector.

[0079] The wavy connecting section 3 can be used to form the installation positioning of the connector, and / or the rotation function, and / or the post-rotation positioning function with the connecting part of the connector. The three functions can be realized simultaneously, or some of the functions can be realized. The wavy connecting section 3 cooperates with different connectors to realize the required functions, so that it is more flexible to use the connector in the storage box 1. The connector cooperates with the connecting section 3 to realize rotation, which is convenient for the user to take the items or tools placed on the connector, and is convenient for efficiently using, sorting the items or tools.

[0080] The crest 3-1 and / or trough 3-2 of the wavy connecting section 3 are arc-shaped. The crest 3-1 of the wavy connecting section 3 is arc-shaped, which is convenient for the connecting part of the connecting piece to rotate. During the rotation of the connecting part of the connecting piece, the friction force of the crest 3-1 on the connecting piece will not be too large, that is to say, the influence of the crest 3-1 on the connecting part of the connecting piece during the rotation is reduced in disguise; the trough 3-2 of the wavy connecting section 3 is arc-shaped, which is convenient for the installation positioning and / or positioning after rotation between the connecting part of the connecting piece and the connecting section 3, and increases the friction between the connecting part and the connecting section 3. In this embodiment 1, the crest 3-1 and trough 3-2 of the wavy connecting section 3 are preferably arc-shaped, which is more convenient to use and more comfortable.

[0081] The wave crests 3 - 1 and the wave troughs 3 - 2 of the connecting section 3 are parallel.

[0082] The angle between the two straight lines formed by the adjacent wave crests 3-1 and the middle wave valley 3-2 is 90° to 170°. In the present embodiment 1, the angle between the two straight lines formed by the adjacent wave crests 3-1 and the middle wave valley 3-2 is 102.7°. Such a design can not only meet the positioning of the connecting member (including installation positioning and positioning after rotation), but also facilitate the rotation of the connecting member, thereby realizing the functions of installation positioning and / or rotation and / or positioning after rotation of the connecting member.

[0083] In addition, the angle between the two straight lines formed by the adjacent wave crests 3-1 and the middle wave trough 3-2 can also be selected as 90°, 100°, 106°, 135° or 170°, which can satisfy the positioning of the connector (including installation positioning and positioning after rotation), and can also facilitate the rotation of the connector, so as to realize the functions of installation positioning and / or rotation and / or positioning after rotation of the connector. The inner wall of the storage space of the storage box 1 is provided with a connecting section 3 with a wavy cross section, including the following two situations: the wavy connecting section 3 is arranged on the inner side wall of the storage box 1 (that is, the connecting section 3 and the storage box 1 are integrated) and the wavy connecting section 3 is arranged on the inner side wall of the transition piece, and the transition piece is connected to the storage space of the storage box 1 (that is, the connecting section 3 and the storage box 1 are split).

[0084] The outer side surface of the transition piece and the inner side surface of the storage box 1 corresponding to the storage space are connected by a tenon structure. For example, dovetail tenons 2-3 are provided on the outer side surface of the transition piece, and first dovetail grooves 1-3 are provided on the inner side surface of the storage box 1. The dovetail tenons 2-3 and the first dovetail grooves 1-3 correspond to each other to form a clamping connection. The transition piece and the box body are firmly fixedly connected. At the same time, the dovetail tenons 2-3 and the first dovetail grooves 1-3 are designed with an inclination, so that the initial stage of the combination of the dovetail tenons 2-3 and the first dovetail grooves 1-3 is wider, which is convenient for alignment and assembly. The middle and rear sections are more tightly engaged and not easy to loosen, and the fastening effect is good. At the top of the inner side surface of the storage box 1 corresponding to the storage space, a protruding pressing strip 1-5 is provided, and at the bottom, a buckle 1-4 is provided for forming a clamping connection with the bottom of the transition piece. A groove 2-5 is provided at the top of the outer side surface of the transition piece. The protruding pressing strip 1-5 and the groove 2-5 are matched, that is, the protruding pressing strip 1-5 and the groove 2-5 are engaged with each other to form a clamping connection. At this time, the top of the transition piece is fixed by the protruding pressing strip 1-5, and the bottom of the transition piece is fixed by the buckle 1-4, so that the transition piece is better fixed in the storage box 1. Even if it is subjected to strong vibration or impact, it can still maintain a tight combination with the storage box 1, that is, the connection between the two is more stable, and at the same time, it can effectively avoid the deformation of the transition piece and avoid the problem of poor tolerance fit precision between the transition piece (such as the middle frame 2) and the connecting piece (such as the card strip) caused by the deformation of the transition piece.

[0085] The top of the transition piece is also provided with a mark 2-2 (such as numbers, letters or symbols, etc.), which is used to help quickly embed the connecting part of the connecting piece (such as the card strip) into the corresponding connecting section 3, or quickly embed the shaft hole 2-1 of the connecting part into the corresponding shaft hole 2-1, so as to realize the quick assembly of the transition piece (such as the middle frame 2) and the connecting piece (such as the card strip), and the use is convenient.

[0086] In this Embodiment 1, preferably, the wavy connecting section 3 is arranged on the inner side wall of the transition piece, and the transition piece is connected in the storage space of the storage box 1; the transition piece can be a transition component with the wavy connecting section 3 arranged in the storage space. The transition piece can be a frame body. The side facing the inside of the storage space of the transition piece is the inner side wall of the transition piece, which is convenient for the wavy connecting section 3 on the transition piece to realize the installation positioning and / or rotation and / or post-rotation positioning of the connecting part of the connecting piece.

[0087] The transition piece in this Embodiment 1 is a frame body (which can also be called the middle frame 2, such as a hollow body with a square cross-section, and the top and / or bottom are open, that is, the transition piece is integral). The inner side walls on the corresponding two sides of the frame body are provided with wavy connecting sections 3. The design of the frame body can keep the distance between the wavy connecting sections 3 on the two inner side walls fixed. In this way, the effect of realizing the installation positioning and / or rotation and / or post-rotation positioning of the connecting part between the wavy connecting section 3 and the connecting piece is better, and the connecting piece is not easy to fall off.

[0088] The transition piece is detachably connected within the storage space of the storage box 1 (for example, the transition piece and the storage box 1 are connected through a tenon structure, without the need for other additional accessories, and the connection method is simple and convenient), which facilitates the replacement of the transition piece. When the transition piece is worn, only the transition piece needs to be replaced, without the need to replace the storage box 1 and the connecting piece, saving costs. At the same time, during the production of products (such as storage boxes and middle frames), only the parts damaged due to assembly (such as storage boxes or middle frames) can be quickly and flexibly replaced, reducing waste of resources.

[0089] Both the wave crests 3-1 and wave troughs 3-2 of the connection section 3 are arranged in the vertical direction, which facilitates pressing the connecting piece vertically downward, so that the connecting part of the connecting piece forms installation positioning and / or rotation and / or post-rotation positioning with the connection section 3, and facilitates taking out the connecting piece vertically upward without the aid of any tools, that is, disassembly and assembly can be achieved manually.

[0090] The bottom end of the connection section 3 forms a third locking portion 3-3 for fixing the position of the connecting piece in the vertical direction. That is to say, the bottom end of the connection section 3 abuts against the first locking portion to achieve the position fixation of the connecting piece in the vertical direction. At this time, the bottom end of the connection section 3 is the third locking portion 3-3. In this way, there is no need to additionally set parts or other designs, and the bottom end of the connection section 3 can play the role of the third locking portion 3-3, making the structure more concise and reliable, and saving materials and production costs. The bottom of the outer side of the transition piece is provided with an extension portion extending downward. The extension portion cooperates with the third locking portion 3-3 to form a space for clamping the first locking portion. The extension portion is arranged in a circle along the middle frame 2 and is called a notch 2-4. In this embodiment 1, the notch 2-4 at the bottom of the middle frame 2 forms a clamping fixation with the buckle 1-4 (that is, the buckle 1-4 and the notch 2-4 are matched).

[0091] Of course, it is also possible to choose to apply a third locking portion 3-3 for fixing the position of the connecting piece in the vertical direction below the connection section 3.

[0092] The connecting section 3 is provided with a shaft hole 2-1 (the shaft hole 2-1 can be a through hole or a blind hole), which is matched with the shaft on the connecting part of the same connecting piece, that is, the shaft can be embedded in the shaft hole 2-1 to help fix the position of the connecting piece. When the connecting piece rotates, it can rotate along the shaft and the shaft hole 2-1. During the rotation process, the connecting section 3 and the connecting piece will not easily fall off, avoiding the articles from being bumped or accidentally dropped. There can be multiple shaft holes 2-1, and different shaft holes 2-1 can be located at different heights, so that the shaft holes 2-1 at different heights can match various shapes of connecting pieces, facilitating the installation positioning and / or rotation and / or post-rotation positioning functions of different connecting pieces. The vertical distance (i.e., the height, taking a single vertical wave crest as an example, the distance from the top of the wave crest to the bottom of the wave crest) of the connecting section 3 can be flexibly adjusted according to needs. The increase and decrease of the length of the connecting section 3 (i.e., the distance between the two ends of the connecting section formed by several vertical wave crests and wave troughs in the horizontal direction) and the size in the height direction will not affect the application of the functional connecting piece (i.e., the connection between the connecting section 3 and the connecting piece realizes the installation positioning and / or rotation and / or post-rotation positioning functions of the connecting piece). That is to say, the connecting section 3 can be large or small and is not limited by size.

[0093] The connecting section 3 has elasticity, which helps the connecting piece that has been installed and positioned to rotate and be positioned after rotation, and at the same time can also increase the friction force between the connecting section 3 and the connecting part of the connecting piece.

[0094] The connecting section 3 is arranged on the inner side walls of the corresponding two sides of the transition piece, such as the left and right sides or the front and back sides. In this embodiment 1, preferably, the connecting section 3 is provided on the left and right sides of the transition piece, which conforms to the storage habit of the user using a connecting piece (such as a strip whose end matches the connecting section 3) to store articles or tools. The connecting piece can be installed at any position on the connecting section 3, so that the position between the connecting pieces can be adjusted according to the actual articles or tools to be stored, without wasting the storage space. This new connection method between the wavy connecting section 3 of the present invention and the connecting part of the connecting piece makes the storage space have a greater tolerance for the strip. That is to say, this new connection method between the wavy connecting section 3 of the present invention and the connecting part of the connecting piece realizes the maximum flexibility in the limited space of the box body (such as by increasing the density of the wave crests and wave troughs of the connecting section).

[0095] The connecting part of the connecting piece is provided with a first locking part for connecting with the third locking part 3-3 to realize the vertical positioning of the connecting piece (the connection here is, for example, a snap connection between the third locking part 3-3 and the first locking part, and between the connecting piece and the connecting section, the user can realize quick disassembly and installation without any tools), and a second locking part for abutting against the connecting section 3 to realize the horizontal positioning of the connecting piece (that is, the horizontal positioning of the connecting piece is realized by using the friction between the connecting section 3 and the second locking part or the blocking of the second locking part by the trough 3-2).

[0096] The connecting part of the connecting piece is provided with a protruding cross bar and / or a protruding dot and / or a protruding shaft for realizing the installation positioning and / or rotation and / or post-rotation positioning of the connecting piece with the connecting section 3. That is to say, the applicable one can be selected among the protruding cross bar (helping the connecting piece to be positioned with the connecting section), the protruding dot (helping the connecting piece to be positioned with the connecting section and increasing the friction), and the protruding shaft (helping the connecting piece to rotate along the protruding shaft). There is no limit to the quantity and the mutual position, as long as it can help the connecting piece to realize the installation positioning and / or rotation and / or post-rotation positioning function with the connecting section, it belongs to the protection scope of the present invention. For example, a single protruding dot can also realize the positioning of the connecting piece with the connecting section, and a single protruding dot and a single protruding shaft can realize the installation positioning and / or rotation and / or post-rotation positioning of the connecting piece with the connecting section.

[0097] For further detailed description, five designs of the connecting part of the connecting piece are listed to illustrate how the connecting part of the specific connecting piece realizes the installation positioning and / or rotation and / or post-rotation positioning function with the connecting section. The design of the connecting part of the connecting piece of the present invention includes but is not limited to the following five types.

[0098] The structure of the connecting part of the first type of connecting piece (i.e., the first card strip 4) is: the first locking part is a protruding cross bar (i.e., the horizontal protruding cross bar 4-1 of the first card strip), the second locking part is two parallel protruding cross bars (i.e., the vertical protruding cross bars 4-2 of the first card strip), and the first locking part and the second locking part are perpendicular. Preferably, the two parallel protruding cross bars of the second locking part (i.e., the vertical protruding cross bars 4-2 of the first card strip) are respectively located at both ends of the first locking part (i.e., the horizontal protruding cross bar 4-1 of the first card strip), increasing the stability of the connecting piece in the horizontal positioning.

[0099] See Figure 2 , the first card strip 4 forms an installation positioning with the connecting section 3. At this time, the horizontal protruding cross bar 4-1 of the first card strip corresponds to the position of the notch 2-4, and the vertical protruding cross bars 4-2 of the first card strip are stuck between the corresponding two wave peaks 3-1.

[0100] The connection structure of the second connecting member (i.e., the second clamping strip 5) is as follows: The first clamping portion is a protruding horizontal strip (i.e., the horizontal protruding strip 5-1 of the second clamping strip), the second clamping portion is a protruding horizontal strip (i.e., the vertical protruding strip 5-2 of the second clamping strip), the first clamping portion and the second clamping portion are perpendicular to each other, and a protruding shaft for clamping and positioning the coaxial hole 2-1 is provided within the right-angle space formed by the first clamping portion and the second clamping portion (i.e., the protruding shaft 5-3 of the second clamping strip, and this protruding shaft 5-3 also helps to fix the position of the connecting member in the vertical direction). See Figure 3 , the second clamping strip forms installation and positioning with the connecting section 3. At this time, the horizontal protruding strip 5-1 of the second clamping strip corresponds to the position of the notch 2-4, and the vertical protruding strip 5-2 of the second clamping strip is stuck between two corresponding wave crests 3-1.

[0101] During use, first disassemble the second clamping strip 5 that has been installed and positioned (i.e., take out the second clamping strip 5 that was first installed and positioned from the middle frame), and then rotate the second clamping strip 5 by 90° and reinstall it into the middle frame to achieve the second installation and positioning state of the connecting member with the middle frame again. See Figure 3 , at this time, the vertical protruding strip 5-2 of the second clamping strip is at or below the position of the notch 2-4, and the horizontal protruding strip 5-1 of the second clamping strip is stuck between two corresponding wave crests 3-1. Figure 4 Before and after rotation, the first clamping portion (i.e., the horizontal protruding strip 5-1 of the second clamping strip) changes from a vertical state to a horizontal state. At this time, the first clamping portion (i.e., the horizontal protruding strip 5-1 of the second clamping strip) can also help to position the connecting member in the vertical direction, and / or at this time, the protruding shaft (i.e., the protruding shaft 5-3 of the second clamping strip) helps to fix the position of the connecting member in the vertical direction. The second clamping portion (i.e., the vertical protruding strip 5-2 of the second clamping strip) changes from a horizontal state to a vertical state. At this time, the second clamping portion (i.e., the vertical protruding strip 5-2 of the second clamping strip) helps to position the connecting member in the horizontal direction.

[0102] Of course, it is also possible to choose to provide more than one protruding dot for forming clamping and positioning with the wave trough 3-2 on the basis of the second clamping strip 5 to replace the protruding shaft (i.e., the protruding shaft 5-3 of the second clamping strip), or add more than one protruding dot for forming clamping and positioning with the wave trough 3-2. The protruding dots are in contact with the connecting section 3 to increase the friction force, help to position the second clamping strip 5 in the vertical or horizontal direction, and improve the positioning stability.

[0103]

[0104] ​The connection structure of the third connecting piece (i.e., the third clamping strip 6) is as follows: The connecting part of the connecting piece is provided with a protruding shaft (i.e., the protruding shaft 6-7 of the third clamping strip), and two rows of protruding dots for abutting against the connecting section 3 (such as increasing friction) are arranged on both sides of the protruding shaft (i.e., the protruding shaft 6-7 of the third clamping strip). Each row has 3 protruding dots (i.e., the first protruding dot 6-1 of the third clamping strip, the second protruding dot 6-2 of the third clamping strip, the third protruding dot 6-3 of the third clamping strip, the fourth protruding dot 6-4 of the third clamping strip, the fifth protruding dot 6-5 of the third clamping strip, and the sixth protruding dot 6-6 of the third clamping strip). The protruding shaft (i.e., the protruding shaft 6-7 of the third clamping strip) matches the shaft hole 2-1 (such as the protruding shaft is inserted into the shaft hole 2-1). See Figure 5 , the third clamping strip 6 forms installation positioning with the connecting section 3. At this time, the tool is in the storage state and the tool is placed horizontally; see Figure 6 , the third clamping strip 6 rotates with the connecting section 3 (rotates around the protruding shaft 6-7 of the third clamping strip) and is positioned after rotation. At this time, the third clamping strip can be in an inclined state, which is convenient for the user to take and place items or tools. That is to say, during the process of the user taking and placing items or tools, it does not occupy the storage space of the storage box 1 (that is, when taking and placing, it is not necessary to take out the entire clamping strip or the nearby components will block it, increasing unnecessary operation steps during taking and placing, so it is faster to take and place, without redundant operations, and has high use comfort, reflecting the use flexibility), improving the utilization rate of the storage space of the storage box 1; see Figure 7 , the third clamping strip 6 forms positioning after rotation with the connecting section 3. At this time, the third clamping strip can be in a vertical state, and the tool is placed vertically, which is convenient for the user to take and place items or tools. That is to say, during the process of the user taking and placing items or tools, it does not occupy the storage space of the storage box 1, improving the utilization rate of the storage space of the storage box 1; In the above three positioning states, each protruding dot abuts against the connecting sections at different positions. For example, the protruding dot can abut against the position between adjacent wave peaks at different positions, forming different states of the connecting piece (installation positioning, rotation, positioning after rotation). At the same time, the protruding dot helps the connecting piece to fix its position in the horizontal direction and / or vertical direction.

[0105] For the protruding dots of the third clamping strip 6, it is not limited to 3. More than 1 can achieve the functions of installation positioning and / or rotation and / or positioning after rotation of the connecting piece. In this embodiment 1, two rows of 3 protruding dots on the third clamping strip are the most suitable and reasonable scheme, and the positioning between the connecting piece and the connecting section 3 is more stable.

[0106] The connection structure of the fourth connecting piece (i.e., the fourth card strip 7) is as follows: The first locking part is a protruding horizontal strip (i.e., the horizontal protruding strip 7-1 of the fourth card strip), and the second locking part is a protruding horizontal strip (i.e., the vertical protruding strip 7-2 of the fourth card strip). The first locking part and the second locking part are perpendicular. See Figure 8 , the fourth card strip forms installation positioning with the connection section 3. At this time, the horizontal protruding strip 7-1 of the fourth card strip corresponds to the position of the notch 2-4, and the vertical protruding strip 7-2 of the fourth card strip is stuck between the corresponding two wave crests 3-1.

[0107] During use, first disassemble the fourth card strip 7 that has been installed and positioned (i.e., take out the fourth card strip 7 that was first installed and positioned in the middle frame 2), and then rotate the fourth card strip 7 by 90° and install it back into the middle frame 2 to realize the second installation and positioning state of the fourth card strip 7 with the middle frame 2 again. See Figure 8 the fourth card strip 7 in the second installation and positioning in the appendix. At this time, the vertical protruding strip 7-2 of the fourth card strip is at or below the position of the notch 2-4, and the horizontal protruding strip 7-1 of the fourth card strip is stuck between the corresponding two wave crests 3-1. Figure 9 Before and after rotation, the first locking part (i.e., the horizontal protruding strip 7-1 of the fourth card strip) changes from a vertical state to a horizontal state. At this time, the first locking part (i.e., the horizontal protruding strip 7-1 of the fourth card strip) can also help the connecting piece to be positioned in the vertical direction. The second locking part (i.e., the vertical protruding strip 7-2 of the fourth card strip) changes from a horizontal state to a vertical state. At this time, the second locking part (i.e., the vertical protruding strip 7-2 of the fourth card strip) helps the connecting piece to be positioned in the horizontal direction.

[0108] Compared with the second card strip 5, the fourth card strip 7 deletes the design of the protruding shaft and can also realize the functions of installation positioning and / or positioning after rotation of the connecting piece.

[0109]

[0110] The connection structure of the fifth connecting piece (i.e., the fifth card strip 8) is as follows: The first locking part is a protruding horizontal strip (i.e., the horizontal protruding strip 8-1 of the fifth card strip), and the second locking part is a protruding horizontal strip (i.e., the vertical protruding strip 8-2 of the fifth card strip). The first locking part and the second locking part are perpendicular. One or more protruding dots for forming snap connection positioning with the connection section 3 are provided in the right-angle space formed by the first locking part and the second locking part. For example, in this embodiment 1, the fifth card strip 8 is provided with two protruding dots (i.e., the first protruding dot 8-3 of the fifth card strip and the second protruding dot 8-4 of the fifth card strip). See Figure 10 , the fifth card strip 8 forms installation positioning with the connection section 3. At this time, the horizontal protruding strip 8-1 of the fifth card strip corresponds to the position of the notch 2-4, and the vertical protruding strip 8-2 of the fifth card strip is stuck between the corresponding two wave crests 3-1.

[0111] ​During use, first remove the fifth card strip 8 that has been installed and positioned (that is, remove the fifth card strip 8 that was first installed and positioned in the middle frame 2 from the middle frame 2), and then rotate the fifth card strip 8 by 90° and reinstall it into the middle frame 2 to achieve the second installation and positioning state of the fifth card strip 8 and the middle frame 2 again. See the fifth card strip 8 that was second installed and positioned in the appendix Figure 10 At this time, the vertical protruding cross bar 8-2 of the fifth card strip is at or below the notch 2-4 of the notch 2-4, and the horizontal protruding cross bar 8-1 of the fifth card strip is stuck between the corresponding two wave peaks 3-1. Figure 11 Before and after rotation, the first locking part (that is, the horizontal protruding cross bar 8-1 of the fifth card strip) changes from a vertical state to a horizontal state. At this time, the first locking part (that is, the horizontal protruding cross bar 8-1 of the fifth card strip) can also help position the connector in the vertical direction. The second locking part (that is, the vertical protruding cross bar 8-2 of the fifth card strip) changes from a horizontal state to a vertical state. At this time, the second locking part (that is, the vertical protruding cross bar 8-2 of the fifth card strip) helps position the connector in the horizontal direction.

[0112] Compared with the second card strip 5, the fifth card strip 8 deletes the design of the protruding shaft and adds the design of two protruding dots, and can also achieve the functions of installing and positioning the connector and / or positioning after rotation.

[0113] Regardless of which installation and positioning method is used, at this time, the first protruding dot 8-3 and the second protruding dot 8-4 of the fifth card strip help increase the friction between the connector and the connection section, improving the positioning stability of the connector, especially the positioning stability of the connector in the horizontal direction.

[0114] And / or the connection part of the connector is provided with a protruding cross bar and / or a protruding dot and / or a protruding shaft for installing and positioning the connector and / or rotating and / or positioning after rotation with the connection section 3.

[0115] The connection section 3 with a wavy cross-section and the connection part of the connector achieve the installation and positioning and / or rotation and / or positioning after rotation of the connector, which is a new connection method, positioning method, and usage method. The structures of the wavy connection section 3 and the connection part of the connector are simpler and more reliable, and the production cost is lower.

[0116]

[0117] ​Various card strips can be set in the storage space in the storage box 1, such as the first card strip 4, the second card strip 5, and the third card strip 6, which can be used individually, or multiple types can be selected, or other card strips that meet the requirements of items or tools, as long as the connecting part of the card strip and the connecting section can achieve installation positioning and / or rotation and / or positioning after rotation, the storage space in the storage box 1 can be used more efficiently, and the utilization rate of the storage space can be improved. In addition, the position of the connecting section and the card strip can also be adjusted at any time according to actual conditions, thereby improving the flexibility and convenience of the card strip and the box body during use.

[0118] The storage box 1 in the present embodiment 1 is provided with an upper cover 1-1 and a lower cover 1-2. A storage space is provided inside the upper cover 1-1 and inside the lower cover 1-2. The inner wall of the storage space is provided with a connecting section 3 with a wavy cross section. A partition is provided between the upper cover 1-1 and the lower cover 1-2, such as a partition plate 9. Figure 18 , the items in the upper and lower storage spaces on the surface collide and wear each other.

[0119] A bendable plug-in portion 9-1 is provided on one side of the partition plate 9, and a plug-in groove 9-1-1 is provided on the plug-in portion 9-1. A first dovetail tenon for forming a first dovetail groove 1-3 is provided on the inner side of the storage box, and a rib 10 is provided between the first dovetail tenon and the inner side wall of the storage box (see Figure 17 ), the plug-in slot 9-1-1 forms a detachable connection with the rib 10; a protrusion 9-1-2 is provided on the plug-in portion 9-1 near the plug-in slot 9-1-1, and when the plug-in slot 9-1-1 is engaged with the rib 10, the protrusion 9-1-2 is engaged between the first dovetail tenon on the inner side of the storage box for forming the first dovetail groove and the inner side of the storage box, thereby strengthening the connection between the plug-in portion 9-1 and the rib 10. Two identical plug-in portions 9-1 are provided on one side of the partition plate 9 in this embodiment 1, and the connection between the partition plate 9 and the storage box is more stable. The cleverness of the design of the partition plate 9 lies in the use of the ribs 10 existing in the storage box itself (that is, the ribs 10 are originally used to help connect the storage box and the middle frame) to achieve a detachable connection of the partition plate 9. There is no additional cost, and there is no need to add additional redundant or special structures to match the partition plate 9. The design is simpler and the use of the partition plate 9 is more flexible. If the partition plate 9 is not used, there will be no sense of missing the storage box. In other words, even if there is no partition plate 9, the ribs 10 will play their original role and will not make the user feel that the partition plate 9 is missing.

[0120] The partition plate 9 is provided with a hole 9 - 2 which penetrates the partition plate 9 . The user can insert a finger into the hole 9 - 2 to freely flip the partition plate 9 .

[0121] The articles designed in the present invention may be small ornaments, and the tools involved may be round-handled tools, hexagonal-handled tools, such as drill bits, screwdriver bits, hole saws, etc., or may be surgical instruments and other tools.

[0130] Preferably, the connecting section 3 is arranged on the inner side wall of the bottom of the storage box. After the connecting piece is fixedly connected or installed and positioned with the storage box, the side of the connecting piece that abuts against the bottom of the storage box also serves as the connecting part of the connecting piece. At this time, the bottom of the connecting piece can also be provided with a protruding cross bar and / or protruding dots and / or a protruding shaft. The connecting part at the bottom of the connecting piece and the connecting section on the inner side wall of the bottom of the storage box cooperate with each other to further improve the installation positioning stability of the connecting piece, especially to help the connecting piece be positioned in the horizontal direction (when the storage box is placed flat) or to help the connecting piece be positioned in the vertical direction (when the storage box is placed upright).

[0131] See Figures 10 to 16 , Specific Embodiment 8. This Embodiment 8 provides a middle frame. The middle frame 2 is a hollow body with openings at the top and / or bottom. The inner side wall of the middle frame 2 is provided with a connecting section 3 with a wavy cross-section, and this connecting section 3 is used to cooperate with the connecting part of the connecting piece with a storage function to achieve the installation positioning and / or rotation and / or post-rotation positioning of the connecting piece.
