[0057] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0058] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0059] like Figure 1-Figure 5 As shown, the tool storage device provided in the embodiment of the present application includes a bracket 100, a first storage rack 200, a second storage rack 300 and a locking mechanism. The bracket 100 has a storage space 140, and the first storage rack 200 and the second storage rack 300 are respectively rotatably connected to the bracket 100.

[0060] The first storage rack 200 is capable of rotating between at least a first storage position and a first use position. The first storage rack 200 has a first mounting surface 210, which is provided with a plurality of first placement positions 211 for placing tools. When the first storage rack 200 is rotated to the first storage position, the tools installed in each first placement position 211 are located within the storage space 140. In other words, when the first storage rack 200 is in the first storage position, the tools stored in the first storage rack 200 are in a storage state. When the first storage rack 200 is in the first use position, the tools stored in the first storage rack 200 are in a state where they can be accessed and stored.

[0061] The second storage rack 300 is capable of rotating between at least a second storage position and a second use position. The second storage rack 300 has a third mounting surface 310, which is provided with a plurality of third placement positions 320 for placing tools. When the second storage rack 300 is rotated to the second storage position, the tools installed in each third placement position 320 are located within the storage space 140. In other words, when the second storage rack 300 is in the second storage position, the tools stored in the second storage rack 300 are in a storage state. When the second storage rack 300 is in the second use position, the tools stored in the second storage rack 300 are in a state where they can be accessed and stored.

[0062] In this embodiment, when the first storage rack 200 is rotated to the first storage position and the second storage rack 300 is rotated to the second storage position, the locking mechanism locks the first storage rack 200 and the second storage rack 300 so that the positions of the first storage rack 200 and the second storage rack 300 are fixed at the storage positions. When taking tools, the locking structure is unlocked, the first storage rack 200 is rotated to the first use position, and the second storage rack 300 is rotated to the second use position to facilitate taking out the tools placed on the first storage rack 200 and the second storage rack 300.

[0063] The tool storage device provided in the embodiment of the present application has a simple structure. The first storage rack 200 and the second storage rack 300 for storing tools are directly mounted on the bracket 100, eliminating the need for a box body for containing tools, reducing the overall volume of the tool storage device, making it easy to carry and store, and occupying a small volume when stored. In addition, the tool storage device is convenient for taking out tools. On the one hand, when taking out tools, the user only needs to rotate the first storage rack 200 to the first use position and the second storage rack 300 to the second use position to take out the tools. It is easy to operate and can meet the needs of users to quickly take out the required tools; on the other hand, when taking out tools, the user rotates the first storage rack 200 to the first use position and the second storage rack 300 to the second use position, that is, the first storage rack 200 and the second storage rack 300 are respectively rotated out of the storage space 140 of the bracket 100, which makes it more convenient for users to take out tools, easy to operate, and convenient for taking and storing tools.

[0064] like Figure 5 As shown, in some embodiments of the present application, when the first storage rack 200 is rotated to the first storage position and the second storage rack 300 is rotated to the second storage position, the first mounting surface 210 faces the side where the second storage rack 300 is located, and the third mounting surface 310 faces the side where the first storage rack 200 is located, and the tools installed in the first placement position 211 and the tools installed in the third placement position 320 are stacked. That is, when the tool storage device is in the closed storage state, the tools installed in the first placement position 211 and the tools installed in the third placement position 320 are arranged in two layers, with the tools installed in the first placement position 211 on one layer and the tools installed in the third placement position 320 on another layer. For example, the tools installed in the first placement position 211 are located in the lower layer and the tools installed in the third placement position 320 are located in the upper layer. The two-layer distribution of tools has a more reasonable spatial layout, and the first storage position and the second storage position are on different sides, so that the overall thickness of the tool storage device is reduced and the width is appropriate, which is convenient for users to hold.

[0065] In some embodiments of the present application, Figure 4As shown, the rotation direction of the first storage rack 200 from the first storage position to the first use position is opposite to the rotation direction of the second storage rack 300 from the second storage position to the second use position. Exemplarily, the rotation direction of the first storage rack 200 from the first storage position to the first use position is clockwise, and the rotation direction of the second storage rack 300 from the second storage position to the second use position is counterclockwise. That is to say, when the first storage rack 200 rotates from the first storage position to the first use position and the second storage rack 300 rotates from the second storage position to the second use position, the first storage rack 200 and the second storage rack 300 rotate toward both sides of the bracket 100. This setting enables the tool storage device to be in the open use state, that is, when the first storage rack 200 is rotated to the first use position and the second storage rack 300 is rotated to the second use position, the tools placed in the first placement position 211 and the tools placed in the second placement position 221 are located on the same side. Exemplarily, the tools placed in the first placement position 211 are facing upward or tilted upward. Similarly, the tools placed in the second placement position 221 are facing upward or tilted upward. This setting makes it easy for users to access tools.

[0066] like Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment, the bracket 100 includes a first supporting portion 110 and a second supporting portion 120 that are opposite to each other. The space between the first supporting portion 110 and the second supporting portion 120 is a storage space 140 of the bracket 100. The first storage rack 200 is disposed between the first supporting portion 110 and the second supporting portion 120 and is rotatably connected to the first supporting portion 110 and the second supporting portion 120, respectively. The second storage rack 300 is disposed between the first supporting portion 110 and the second supporting portion 120 and is rotatably connected to the first supporting portion 110 and the second supporting portion 120, respectively.

[0067] The first support portion 110 and the second support portion 120 can be connected through the first storage rack 200 and the second storage rack 300, or can be connected through the connection portion 130. For example, in this embodiment, Figure 1 and Figure 3As shown, the bracket 100 further includes a connecting portion 130, which connects the first support portion 110 and the second support portion 120. The side of the connecting portion 130 facing the storage space 140 faces the second storage rack 300, with a gap therebetween. The side of the connecting portion 130 facing the storage space 140 is provided with a fourth placement position for tools. When the first storage rack 200 is rotated to the first storage position and the second storage rack 300 is rotated to the second storage position, the tools installed in the third placement positions 320 are located farther away from the connecting portion 130 than the tools installed in the first placement positions 211. In other words, the tool storage device is opened and closed (from an open, in-use state to a closed, storage state) by first rotating the first storage rack 200 to the first storage position and then rotating the second storage rack 300 to the second storage position. A fourth placement position is set on the side of the connecting portion 130 facing the second storage rack 300, which rationally utilizes the space between the second storage rack 300 and the connecting portion 130, making the layout of the tool storage device more reasonable and storing more tools in a smaller volume.

[0068] like Figure 1 and Figure 2 As shown, to facilitate opening the second storage rack 300, a handle protrusion 330 is provided on the side of the second storage rack 300 facing away from the connecting portion 130. Since the second storage rack 300 is located on the outside, when opening the tool storage device (from the closed storage state to the open use state), the second storage rack 300 must first be rotated out. The provision of the handle protrusion 330 allows the user to deflect the end surface of the handle protrusion 330 to unlock and rotate the second storage rack 300 out, making operation more convenient for the user.

[0069] For example, Figure 4 As shown, the first placement position 211 is a socket structure, and the first placement position 211 is configured to insert and place the bit 400. The third placement position 320 is a socket structure, and the third placement position 320 is configured to insert and place the bit 400. The fourth placement position includes a ratchet wrench placement position 131 for placing a ratchet wrench 600 and a bit extension rod placement position 132 for placing a bit extension rod 700. In other words, the tool storage device provided in this embodiment of the application can store two rows of bits 400, a ratchet wrench 600, and a bit extension rod 700.

[0070] In some embodiments of the present application, the first storage rack 200 further includes a second mounting surface 220, which is opposite the first mounting surface 210. The second mounting surface 220 is provided with a plurality of second placement locations 221 for placing tools. In other words, tool placement locations are provided on both the front and back sides of the tool placement plate 230 (described below) of the first storage rack 200. This configuration enables the tool storage device to store and accommodate a larger number of tools.

[0071] For example, the second placement position 221 is a mounting protrusion, and the second placement position 221 is configured to accommodate a socket 500. In other words, the tool storage device provided in this embodiment of the application can accommodate two rows of bits 400, a row of sockets 500, a ratchet wrench 600, and a bit extension rod 700. This tool storage can be used as a cycling tool set, with a compact overall size, easy to hold and carry, convenient access to tools, and a comprehensive tool set.

[0072] In some embodiments of the present application, the locking mechanism includes a first locking mechanism and a second locking mechanism. The first locking mechanism is configured to lock the first storage rack 200 when the first storage rack 200 is rotated to the first storage position, and the second locking mechanism is configured to lock the second storage rack 300 when the second storage rack 300 is rotated to the second storage position. In other words, the locking mechanism is divided into two parts, one part locks the first storage rack 200, and the other part locks the second storage rack 300. That is, when the first storage rack 200 is rotated to the first storage position, the first locking mechanism locks the first storage rack 200, and when the second storage rack 300 is rotated to the second storage position, the second locking mechanism locks the second storage rack 300.

[0073] Exemplarily, the first locking mechanism includes a first locking portion and a second locking portion with the same structure, and the first locking portion and the second locking portion are respectively located on opposite sides of the first storage rack 200. The first locking portion includes a first clamping portion and a second clamping portion, the first clamping portion is provided on the side of the first storage rack 200 facing the first support portion 110, and the second clamping portion is provided on the first support portion 110. When the first storage rack 200 is rotated to the first storage position, the first clamping portion and the second clamping portion cooperate to lock the first storage rack 200 and the first support portion 110. Exemplarily, as Figure 1 、 Figure 2 and Figure 3 As shown, the first engaging portion includes at least one first engaging protrusion 250, and the second engaging portion includes at least one first engaging groove 111. The number of first engaging protrusions 250 is the same as the number of second engaging grooves 260, and they correspond one to one. When the first storage rack 200 is rotated to the first storage position, the first engaging protrusion 250 is engaged with the corresponding first engaging groove 111. The engaging protrusion and the engaging groove cooperate to lock the first storage rack 200 and the first support portion 110, so that the first storage rack 200 cannot continue to rotate forward or backward. When unlocking is required, the first storage rack 200 can be moved out of the first engaging groove 111 by forcing the first storage rack 200, so that the first storage rack 200 can be rotated from the first storage position to the first use position. In this embodiment, the second locking portion has the same structure as the first locking portion and will not be described in detail here.

[0074] For example, Figure 1 、 Figure 2 and Figure 3 As shown, the first storage rack 200 includes a tool placement plate 230 and two extension plates 240. A first placement position 211 and a second placement position 221 are respectively provided on the front and back of the tool placement plate 230. The two extension plates 240 are disposed on opposite sides of the tool placement plate 230, one on each side of the tool placement plate 230 where the first placement position 211 is provided. The second locking mechanism includes a third locking portion and a fourth locking portion, both of identical structure, located on either side of the second storage rack 300. The third locking portion includes a third engaging portion and a fourth engaging portion. The third engaging portion is located on the side of the second storage rack 300 facing the first support portion 110, while the fourth engaging portion is located on the side of the extension plate 240 closer to the first support portion 110. When the first storage rack 200 is rotated to the first storage position and the second storage rack 300 is rotated to the second storage position, the third engaging portion and the fourth engaging portion cooperate to lock the second storage rack 300 and the first storage rack 200 together. Exemplarily, the third engaging portion includes a second engaging protrusion 340, and the fourth engaging portion includes a second engaging slot 260. When the first storage rack 200 is rotated to the first storage position and the second storage rack 300 is rotated to the second storage position, the second engaging protrusion 340 engages with the corresponding second engaging slot 260. The engaging protrusion and the engaging slot cooperate to lock the second storage rack 300 and the first storage rack 200, so that the second storage rack 300 cannot continue to rotate forward or backward. When unlocking is required, the second storage rack 300 can be forcibly pried out of the second engaging protrusion 340 from the second engaging slot 260, so that the second storage rack 300 can be rotated from the second storage position to the second use position. In this embodiment, the fourth locking portion has the same structure as the third locking portion and will not be described in detail here.
