[0004] This utility model provides a tool storage device. By setting a locking position and a storage position of the locking element, the tool can be locked or unlocked. In different application states, the tool can be firmly fixed and easily retrieved. The structure is simple and lightweight.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tool storage device, including a storage rack, on which several sets of upwardly inclined storage blocks are provided, and storage positions are formed between different sets of storage blocks, with locking components provided between each set of storage blocks; a locking component is hinged to the bottom end of the storage rack, and a locking groove is provided on one side of the top end, and a locking component storage groove is provided on the other side, with the locking component engaging in the locking groove or the locking component storage groove.

[0006] Preferably, each set of storage blocks includes storage blocks located on both sides of the storage rack, with the locking element positioned a certain distance from the base of the storage block. Several sets of storage blocks are linearly arranged along the height of the storage rack. A handle is located at the top of the storage rack. The vertical distance between the sets of storage blocks is the same, and they are evenly distributed along the height of the rack. The two storage blocks on each side of the rack within each set are on the same horizontal plane. The distance between any two storage blocks within a set gradually decreases from top to bottom along the height of the storage block. This design makes the structure of the storage blocks more rational, better accommodating tools of different sizes and facilitating the categorization and storage of tools. Simultaneously, the handles make it easier for users to carry the storage device, improving usability. The evenly distributed spacing and gradually decreasing spacing between the storage blocks make the tools more stable during storage, preventing them from shaking.

[0007] Preferably, a first limiting block is provided on the upper surface of the storage block, and the first limiting block is located at the opening of the storage position. The cross-section of the storage block is polygonal, and the opposite faces of different groups of storage blocks form the two side walls of the storage position, with the opposite faces of different groups of storage blocks arranged parallel to each other. Reinforcing ribs are provided on the side walls of the storage block. The first limiting block effectively prevents tools from slipping out of the storage position, improving the stability of tool storage. The polygonal cross-section of the storage block and the parallel opposite faces make the shape of the storage position more regular, better accommodating tools of different shapes. The reinforcing ribs enhance the structural strength of the storage block and extend the service life of the storage device.

[0008] Preferably, the locking element is a rectangular frame with a locking groove opening towards the storage compartment. A locking block is provided on the side wall of the opening. The locking block is used to lock the locking element; when the top of the locking element engages with the locking groove, a locking position is formed, thus locking the tool placed in the storage compartment. A distance is provided between the locking element and the base of the storage block to allow space for the tool placed in the storage compartment. The rectangular frame locking element has a simple structure, is easy to manufacture and install. The design of the locking groove and locking block ensures reliable locking of the locking element, guaranteeing the tool's stability during storage. The distance between the locking element and the base of the storage block provides sufficient space for the tool.

[0009] Preferably, the bottom of the storage rack is provided with a rotating plate, one end of which is hinged to the locking element, and the other end is hinged to the lower surface of the storage rack. One end of the rotating plate has a first rotating groove, within which the bottom frame of the locking element is positioned and can rotate. The other end has a second rotating groove. The lower surface of the storage rack has a pivot seat with a rotating shaft positioned thereon. The rotating shaft is located within the second rotating groove, allowing the rotating plate to rotate along the shaft. The pivot seat is positioned in the middle of the lower surface of the storage rack, and the length of the rotating plate is greater than half the width of the lower surface of the pivot seat. This rotating plate design allows for more flexible movement of the locking element, enabling easy switching between the locked and stored positions. The rotation of the rotating plate allows the locking element to quickly move to the desired position, improving the speed of tool storage and retrieval. The pivot seat and the rotating shaft provide stable support for the rotation of the rotating plate, ensuring the reliability of the locking element's movement.

[0010] Preferably, a second limiting block is provided at the bottom end of the opening side of the locking component storage slot. The locking component is flipped into the locking component storage slot by rotating the rotating plate. The locking component is then flipped onto the back of the storage rack by rotating the rotating plate. The back of the storage rack has several locking component fixing slots for fixing the locking component in the storage position. The second limiting block effectively prevents the locking component from slipping out of the storage slot, ensuring the stability of the locking component in the stored state. The locking component fixing positions on the back of the storage rack provide additional fixing positions for the locking component, making the locking component more secure when stored and preventing it from loosening due to external factors.

[0011] Preferably, the locking element is a "U"-shaped frame with an open end. Both sides of the open end are hinged to rotating grooves at the bottom of the storage rack. Rotating rods are provided on both sides of the open end, horizontally positioned outwards. These rods can rotate within the rotating grooves and move along the length of the grooves. The "U"-shaped frame locking element has a simple structure and good flexibility. The rotating rod design allows the locking element to move and rotate easily within the rotating grooves, enabling quick switching between the locking position and the storage position, thus improving the efficiency of the tool storage device.

[0012] Preferably, the rotating groove is arranged along the width of the storage rack and communicates with the locking component storage groove. This design makes the movement path of the locking component smoother and reduces the resistance encountered by the locking component during movement. The communication between the rotating groove and the locking component storage groove provides sufficient space for the movement of the locking component, ensuring that the locking component can smoothly enter the storage groove and improving the reliability of the tool storage device.

[0013] Preferably, the locking component storage slot is linearly aligned with the height of the storage rack, and its length is greater than the length of the locking component. After the rotating rod moves from one end of the rotating slot to the other, the locking component is rotated, causing it and the locking component storage slot to be on the same plane. This pushes the locking component along the locking component storage slot. When the rotating rod of the locking component moves to the second limiting block and its full length is positioned within the locking component storage slot, the locking component is in its stored position. The length design of the locking component storage slot ensures that the locking component is completely inserted into the storage slot during storage, preventing the locking component from being exposed and affecting the overall appearance and usability of the tool storage device. Through the cooperation of the rotating rod and the second limiting block, the locking component is stably fixed within the storage slot, improving the stability of the tool storage device.

[0014] Preferably, a second limiting block is provided at the top of the locking component storage slot, and the second limiting block respectively engages with both sides of the opening end of the locking component. The second limiting block engages with the rotating rod. The design of the second limiting block can effectively prevent the locking component from sliding in the storage slot, ensuring the stability of the locking component in the stored state. At the same time, the engagement of the second limiting block with the rotating rod further enhances the fixing effect of the locking component in the storage slot, preventing the locking component from loosening due to external factors.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a tool storage device. By setting the locking position and storage position of the locking element, the tool can be locked or unlocked. In different application states, the tool can be fixed firmly and can be easily accessed. The structure is simple and lightweight. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Tool storage devices are used to store tools of different sizes or types. There are three common usage states: the first is to place them horizontally in drawers, cabinets or countertops; the second is to display them vertically; and the third is to move them by the handle. How to ensure that the tools can be firmly fixed and easily accessed in all three states is one of the technical problems that need to be solved.

[0027] Example 1.

[0028] like Figure 1 As shown, the main body of this tool storage device is the storage rack 1, which provides a supporting frame for the entire device. The storage rack 1 has multiple sets of upward-sloping storage blocks 2, arranged in pairs on both sides of the rack. Different sets of blocks form storage spaces for various tools. Locking elements 5 are installed between each set of blocks 2, engaging with the locking slot 6 or locking element storage slot 13 at the top of the rack 1 to lock or unlock the tools, adapting to different usage scenarios.

[0029] like Figure 1As shown, several sets of storage blocks 2 are linearly arranged along the height of the storage rack 1, with equal vertical spacing, ensuring the overall aesthetics and neatness of the storage rack 1. This uniform layout also allows users to quickly find suitable storage locations based on tool length. Within each set of storage blocks 2, the two blocks located on either side of the storage rack 1 are on the same horizontal plane, allowing tools to be placed stably in their storage positions. Notably, the distance between two storage blocks 2 within each set gradually decreases from top to bottom along the height of the storage blocks 2. This design fully considers the storage needs of tools of different sizes; for example, longer tools can be placed in the larger-spaced upper storage positions, while shorter tools can be placed in the smaller-spaced lower storage positions, thereby improving the space utilization of the storage device and making the tools more stable and less prone to shaking during storage.

[0030] like Figure 1 As shown, the upper surface of the storage block 2 is provided with a first limiting block 3, located at the opening of the storage compartment. When a tool is placed in the storage compartment, the first limiting block 3 effectively prevents the tool from slipping out, greatly improving the stability of tool storage. The cross-section of the storage block 2 is polygonal, and the opposite faces of different groups of storage blocks 2 are parallel to each other. This makes the shape of the storage compartment more regular and can better fit tools of different shapes. Whether it is a round pipe tool or a square wrench, a suitable placement position can be found in the storage compartment. In addition, the side walls of the storage block 2 are provided with reinforcing ribs, which enhance the structural strength of the storage block 2. In actual use, even with frequent placement and removal of tools, the storage block 2 can maintain good structural integrity, extending the service life of the storage device.

[0031] like Figure 1 and Figure 2 As shown, the bottom of the storage rack 1 is connected to the locking element 5 via a hinge, allowing the locking element 5 to rotate freely. At the top of the storage rack 1, one side has a locking groove 6, and the other side has a locking element storage groove 13. When it is necessary to lock the tool, the locking element 5 is rotated upwards to engage with the locking groove 6, thus firmly fixing the tool in its storage position. When it is necessary to retrieve the tool, the locking element 5 is removed from the locking groove 6 and rotated into the locking element storage groove 13 at the top of the storage rack 1, at which point the tool is unlocked for easy access. The locking element 5 is positioned a certain distance from the base of the storage block 2, providing sufficient space for the tool.

[0032] The storage rack 1 has a handle 4 at the top. The handle 4 is designed with ergonomic principles in mind, and its shape and size make it easy for users to grip. When users need to carry the storage device, they can easily lift the storage rack 1 by simply holding the handle 4. This design greatly improves the ease of use, providing convenience whether moving the storage device indoors or carrying it to an outdoor workplace. When storing tools, select a suitable storage location according to the size and shape of the tools and place them between the storage blocks 2. Next, rotate the locking piece 5 upwards so that it engages with the locking groove 6, completing the locking of the tools. When it is necessary to retrieve the tools, first remove the locking piece 5 from the locking groove 6, rotate it into the locking piece storage groove 13, and then the tools can be easily retrieved.

[0033] like Figure 1 As shown, this tool storage device is designed with a strong emphasis on the cooperation between the locking element 5 and the locking groove 6 to ensure the safety and stability of tool storage. The locking element 5 adopts a rectangular frame structure, which is not only simple and easy to manufacture and install, but also provides a reliable locking function in actual use. The locking groove 6 opens towards the storage position, and a locking block 7 is provided on the side wall of the opening. The design of the locking block 7 is extremely ingenious. When the top of the locking element 5 is engaged in the locking groove 6, the locking block 7 can lock the locking element 5, thereby forming a locking position and effectively locking the tools placed in the storage position.

[0034] In practical terms, when tools need to be stored, the operator places the tool in the storage compartment and then rotates the locking member 5 upwards, ensuring that the top of the locking member 5 accurately engages with the locking groove 6. At this point, the locking block 7 activates, firmly securing the locking member 5 to prevent accidental dislodgement and ensuring the tool's secure storage. The locking member 5 is positioned a distance from the base of the storage block 2; this design allows space for tools placed in the storage compartment. When storing large or irregularly shaped tools, this distance ensures that the tools can be placed smoothly in the storage compartment, avoiding interference with the locking member 5, providing sufficient storage space, and improving the compatibility of the storage device with different types of tools.

[0035] like Figure 3As shown, to allow the locking member 5 to move more flexibly and easily switch between the locking position and the storage position, a rotating plate 8 is provided at the bottom of the storage rack 1. One end of the rotating plate 8 is hinged to the locking member 5, and the other end is hinged to the lower surface of the storage rack 1. One end of the rotating plate 8 is provided with a first rotating groove 9, and the bottom frame of the locking member 5 is set in the first rotating groove 9 and can rotate within the first rotating groove 9. This allows the locking member 5 to rotate flexibly with the rotating plate 8 as support. The other end of the rotating plate 8 is provided with a second rotating groove 10, and the lower surface of the storage rack 1 is provided with a pivot seat 12. A pivot 11 is provided on the pivot seat 12, and the pivot 11 is set in the second rotating groove 10. The rotating plate 8 can rotate along the pivot 11. The pivot seat 12 is located in the middle of the lower surface of the storage rack 1 to ensure the balance of the rotating plate 8 when rotating. The length of the rotating plate 8 is greater than half the width of the lower surface of the storage seat. This design can provide sufficient rotation space for the locking member 5 to ensure that the locking member 5 can rotate smoothly to the required position.

[0036] In actual operation, when tools need to be retrieved, the operator only needs to gently push the locking element 5, and the rotating plate 8 will rotate around the rotating shaft 11, simultaneously moving the locking element 5 from the locked position to the storage position. The setting of the rotating shaft seat 12 and the rotating shaft 11 provides stable support for the rotation of the rotating plate 8. After extensive testing and verification, even after multiple frequent rotation operations, the connection between the rotating plate 8 and the rotating shaft 11 remains stable, ensuring the reliability of the movement of the locking element 5 and greatly improving the speed of tool storage and retrieval.

[0037] like Figure 2 As shown, a second limiting block 14 is provided at the bottom of the opening side of the locking component storage slot 13. When the locking component 5 is flipped into the locking component storage slot 13 by rotating the rotating plate 8, the second limiting block 14 can effectively prevent the locking component 5 from slipping out of the storage slot. During daily use, the storage device may be subjected to vibration or external impact. Without the second limiting block 14, the locking component 5 may fall out of the storage slot, affecting the retrieval and storage of the tool. The presence of the second limiting block 14 ensures the stability of the locking component 5 in the stored state.

[0038] like Figure 2As shown in the figure, a number of locking part fixing grooves 15 are provided on the back of the storage rack 1 for fixing the locking part 5 in the storage position. When the locking part 5 rotates into the storage groove on the back of the storage rack 1, it can be further fixed in the locking part fixing groove 15. This design provides an additional fixing position for the locking part 5, making the locking part 5 more secure during storage and preventing it from loosening due to external factors. During the actual installation process, the position of the locking part fixing groove 15 is precisely calculated and designed to ensure that the locking part 5 can be accurately inserted, further enhancing the stability and reliability of the storage device. When tools need to be retrieved, push the locking part 5, and the rotating plate 8 rotates around the rotating shaft 11, driving the locking part 5 to move into the locking part storage groove 13 on the back of the storage rack 1 and be inserted into the locking part fixing groove 15. At this time, the tools can be taken out.

[0039] Embodiment 2.

[0040] In the field of tool storage, convenience and stability are important indicators for measuring the quality of a storage device. In Embodiment 2 of the tool storage device of the present utility model, through the unique "J-shaped" locking part 5 design and the matching structures such as the rotating groove 17 and the locking part storage groove 13, the tool storage and retrieval experience is further optimized. While achieving firm fixation of the tools, the use efficiency is greatly improved.

[0041] As Figure 4 shown, the locking part 5 adopts a "J-shaped" frame. This structural design is simple and clear, not only easy to process and manufacture, but also endows the locking part 5 with good flexibility. One end of the "J-shaped" frame is open, and both sides of the open end are hinged in the rotating groove 17 at the bottom end of the storage rack 1. On both sides of the open end, rotating rods 16 are respectively provided, and the rotating rods 16 are horizontally arranged towards the outside. During actual operation, the rotating rods 16 can rotate flexibly in the rotating groove 17 and can freely move along the groove length direction of the rotating groove 17. When the tool needs to be locked, the operator rotates the rotating rod 16 to drive the locking part 5 to move upward until the locking part 5 reaches the appropriate position to lock the tool; when the tool needs to be retrieved, rotate the rotating rod 16 in the reverse direction to make the locking part 5 move downward to release the locking of the tool. This design enables the locking part 5 to move and rotate conveniently in the rotating groove 17, realizing the rapid switching of the locking part 5 between the locking position and the storage position, and greatly improving the use efficiency of the tool storage device.

[0042] As Figure 8As shown, the rotating groove 17 is linearly arranged along the width direction of the storage rack 1 and communicates with the locking component storage groove 13. This design provides a smooth path for the movement of the locking component 5. During the process of the locking component 5 switching from the locked position to the storage position, the linear design of the rotating groove 17 reduces the resistance when the locking component 5 moves, allowing the locking component 5 to move smoothly. The communication between the rotating groove 17 and the locking component storage groove 13 provides sufficient space for storing the locking component 5. When the locking component 5 needs to enter the storage groove, it can smoothly reach it by moving along the rotating groove 17, ensuring the reliability of the tool storage device. In actual production, the dimensions of the rotating groove 17 are precisely calculated and perfectly matched with the rotating rod 16 of the locking component 5, further improving the smoothness of the movement of the locking component 5.

[0043] like Figure 5 and Figure 7 As shown, the locking component storage slot 13 is linearly arranged along the height direction of the storage rack 1, and its length is greater than the length of the locking component 5. This design ensures that the locking component 5 can be completely inserted into the storage slot when stored, avoiding the locking component 5 being exposed and affecting the overall appearance and usability of the tool storage device. After the rotating rod 16 moves from one end of the rotating slot 17 to the other end, the operator only needs to rotate the locking component 5 to make the locking component 5 and the locking component storage slot 13 on the same plane, and then push the locking component 5 to move along the locking component storage slot 13. When the rotating rod 16 of the locking component 5 moves to the second limit block 14, and the entire length of the locking component 5 is set in the locking component storage slot 13, the locking component 5 is in the storage position.

[0044] like Figure 6 As shown, a second limiting block 14 is provided at the top of the locking component storage slot 13. The second limiting block 14 engages with both sides of the opening end of the locking component 5, and also engages with the rotating rod 16. The design of the second limiting block 14 is crucial to ensuring the stability of the locking component 5 within the storage slot. In actual use, the tool storage device may be subjected to vibration or external impact. The second limiting block 14 effectively prevents the locking component 5 from sliding within the storage slot, ensuring the stability of the locking component 5 in its stored state. Simultaneously, the engagement of the second limiting block 14 with the rotating rod 16 further enhances the fixing effect of the locking component 5 within the storage slot, preventing the locking component 5 from loosening due to external factors, and providing a reliable guarantee for the stable operation of the tool storage device.

[0045] When tools need to be stored, place them in the storage compartment and rotate the rotating rod 16 of the locking member 5 to move the locking member 5 upwards until it securely locks the tool. When tools need to be retrieved, rotate the rotating rod 16 in the opposite direction to move the locking member 5 downwards and release the tool. To store the locking member 5, first move the rotating rod 16 along the rotating groove 17 to the other end, then rotate the locking member 5 until it is flush with the locking member storage groove 13, and then push the locking member 5 along the locking member storage groove 13 until the rotating rod reaches the second limit block 14, completing the storage of the locking member 5.

[0046] When the tool storage device is about to be moved, the locking element 5 can be placed in the locking position to lock the tool and prevent it from easily coming out. When the tool storage device is in the display state or placed horizontally, the locking element 5 can be placed in the storage position. By adjusting the position of the locking element 5, the tool can be locked or unlocked. In this way, the tool can be firmly fixed and easily accessed in different application states.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
