Description

Technical Field

[0001] This application relates to the field of consumer goods technology, and more specifically to a toolbox. Background Technology

[0002] A toolbox is a container used to store tools, equipment, and various miscellaneous items, widely used in industrial production, home repair, outdoor activities, fishing, and many other scenarios. Traditional toolboxes typically use a hinged lid connected to the body, secured with locks or buckles. Many of these buckles are prone to accidental opening during transport due to vibration or accidental contact, causing items inside to scatter and compromising security. Furthermore, traditional buckles are complex in structure, cumbersome to install and remove, increasing production costs and user difficulty. To address the aforementioned issues, a utility model patent with authorization announcement number CN220378074U discloses a toolbox buckle. The buckle comprises an upper fastening portion and a lower symmetrical rotating portion. A connecting hole is horizontally provided on the rotating portion, and a lever is provided below the rotating portion. The rotating portion and the lever are hinged together by a pivot passing through the connecting hole. A connecting shaft is rotatably connected to the upper part of the lever, and both ends of the connecting shaft are fixed to the toolbox housing. An unlocking button, rotatably connected to the pivot, is provided inside the lever. A spring connects the front of the unlocking button to the lever, and the back engages with a stop block on the toolbox. A groove that mates with the connecting shaft is also provided on the back of the buckle. When the buckle is fastened to the top cover of the toolbox, the stop block and the hook are engaged. In this technical solution, the buckle is locked by an unlocking button and a spring, enhancing the locking performance. However, the toolbox buckle is fixed to the toolbox housing by a connecting shaft. To install the connecting shaft, precise through holes need to be pre-drilled on the housing. The size and positional accuracy of the through holes are required to be high; otherwise, problems such as the connecting shaft not being installed securely or the buckle not rotating properly may occur, increasing the complexity and cost of housing processing. On the other hand, during the injection molding process, the through hole structure on the housing requires a complex mold design. During demolding, the through holes are prone to damage or deformation, affecting product quality and increasing mold cost and demolding difficulty. Furthermore, the toolbox buckle involves multiple components, such as the rotating shaft, connecting shaft, buckle seat, and button, making the assembly process complex and prone to errors. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a toolbox in which the buckle is rotatably connected to the mounting groove on the box body through a rotating shaft. The machining requirements of the mounting groove are relatively low, which reduces the production cost and machining difficulty. Moreover, it is only necessary to install the buckle on the box body. There is only one buckle as the component, which reduces the production cost and makes the installation simple and labor-saving.

[0004] This application provides a toolbox, including a box body and a cover that are rotatably connected. The cover can be rotatably opened or closed relative to the box body. It also includes a buckle. The side wall of the buckle is provided with a rotating shaft. The box body is provided with a mounting groove adapted to the rotating shaft. The rotating shaft is connected to the mounting groove so that the buckle is rotatably installed on the box body. One end of the buckle is provided with a hook portion. The cover is provided with a fastening portion adapted to the hook portion. One end of the buckle is subjected to force to rotate and connect to the fastening portion. The other end of the buckle is subjected to force to rotate and disengage the hook portion from the fastening portion.

[0005] In this technical solution, the toolbox consists of a box body and a lid. The lid is connected to the box body via a rotatable connection, enabling opening and closing. A latch connects the box body and lid for locking and unlocking. The latch connects to a mounting groove on the box body via a rotating shaft, allowing the latch to rotate around the shaft. The mounting groove does not require complex processing techniques or high-precision equipment, reducing processing difficulty and cost. The latch's hook portion can flexibly connect and disengage with the latching portion on the lid. The tight fit between the hook portion and the latching portion effectively prevents the toolbox from accidentally opening during use. When the user presses one end of the latch with the hook portion, the hook portion engages with the latching portion, locking the lid and box body, preventing the lid from rotating open. When the user presses the other end of the latch away from the hook portion, the latch rotates, and... The lever principle drives the hook part to disengage from the fastening part, realizing the locking and unlocking of the cover and the box. The cover can be rotated to open, and the user can lock and unlock the cover with a simple pressing operation. The operation is simple and effortless. On the other hand, traditional buckle structures usually require springs to provide elastic force to achieve automatic reset of the buckle or enhance the stability of the fastening. However, the buckle provided in this application can achieve the function without relying on springs. The buckle is connected to the mounting groove on the box through a rotating shaft. The hook part of the buckle rotates to connect or disengage with the fastening part on the cover. The movement of the buckle depends entirely on the rotation of the rotating shaft, reducing the number and complexity of parts. The toolbox has very few parts, with only one buckle connected to the box through a rotating shaft. No additional fasteners or complicated assembly steps are required. Assembly can be completed simply by installing the buckle on the box, simplifying the production and assembly process.

[0006] As an improvement, the housing is provided with a limiting structure, and the buckle is provided with a snap-fit ​​part adapted to the limiting structure. The limiting structure and the snap-fit ​​part cooperate to keep the buckle confined on the housing. In this technical solution, the limiting structure designed on the housing provides a fixed assembly position and movement constraint for the buckle. The snap-fit ​​part on the buckle, through cooperation between the snap-fit ​​part and the limiting structure, further limits the buckle's installation on the housing, preventing it from falling off and making the buckle's rotation axis installation more reliable. The abutting cooperation between the limiting structure and the snap-fit ​​part ensures that the buckle will not easily shift or loosen after installation. The limiting structure provides a clear assembly position for the buckle, ensuring that the buckle can be quickly and accurately positioned during installation, reducing assembly errors. Preferably, the limiting structure is in the shape of a boss, and the snap-fit ​​part abuts against the boss-shaped limiting structure, thereby limiting the buckle and preventing it from loosening or falling off under vibration or external force, improving the buckle's reliability.

[0007] As an improvement, the end of the latching part is semi-circular. When the latch is rotated under force, the end of the latching part abuts against the limiting structure and rotates relative to the limiting structure. In this technical solution, the semi-circular end of the latching part is designed so that the latching part can achieve smoother rotation and abutment when it cooperates with the limiting structure. The curved surface design of the semi-circular structure reduces stress concentration at the contact point and reduces the risk of wear. When the latch is rotated under force, the semi-circular end of the latching part abuts against the limiting structure. This abutment is not a rigid collision, but a smooth relative movement is achieved through the contact between the curved surface of the semi-circular end and the limiting structure. The design of the semi-circular end allows the latching part to slide or roll along the contour of the limiting structure during the rotation of the latch. The rotation of the latch is not restricted by the latching part, thereby achieving stable rotation and limiting functions.

[0008] As an improvement, the locking part is arranged coaxially with the rotating shaft, and the locking part cooperates with the limiting structure to assist the rotation of the rotating shaft. In this technical solution, the locking part and the rotating shaft are arranged coaxially, that is, the central axis of the locking part coincides with the central axis of the rotating shaft, so that the movement of the locking part and the rotation of the rotating shaft are closely coupled, and the two always maintain a consistent axial relationship during the movement. The cooperation between the locking part and the limiting structure not only plays a limiting role, but also assists the rotation of the rotating shaft. During the rotation of the rotating shaft, the locking part also acts as a rotating shaft through its semi-circular end. The movement of the locking part can be directly transmitted to the rotating shaft, making the rotation of the rotating shaft more stable and smooth, reducing the need for additional guiding or limiting components, and simplifying the overall structure.

[0009] As an improvement, the buckle is provided with reinforcing ribs connected to the snap-fit ​​portion, and at least two reinforcing ribs are provided. In this technical solution, the reinforcing ribs are directly connected to the snap-fit ​​portion, and their function is to enhance the structural strength and rigidity of the snap-fit ​​portion, so that the snap-fit ​​portion can remain stable when subjected to external forces, reducing deformation or damage caused by local stress concentration. The provision of at least two reinforcing ribs, through the synergistic effect of multiple reinforcing ribs, distributes stress more evenly, further improving the overall strength and stability of the buckle. The design of multiple reinforcing ribs can also be flexibly arranged according to the shape of the buckle and the stress conditions, which can extend the service life of the product.

[0010] As an improvement, the end of the rotating shaft is provided with a guide ramp adapted to the mounting groove. The rotating shaft is inserted into the mounting groove by cooperating with the guide ramp. In this technical solution, the end of the rotating shaft is designed with a guide ramp whose shape and angle are adapted to the entrance part of the mounting groove. The main purpose is to allow the rotating shaft to enter the mounting groove more smoothly through the guiding effect of the ramp, reducing friction and resistance during the insertion process. Through the guidance of the guide ramp, the rotating shaft can be more accurately positioned in the mounting groove, thereby improving the assembly accuracy of the entire snap-fit ​​structure. This matching method not only simplifies the assembly process but also reduces the risk of component damage due to improper assembly.

[0011] As an improvement, the mounting groove has a U-shaped opening structure. In this technical solution, the mounting groove adopts a U-shaped opening design, that is, the cross-section of the groove is "U"-shaped, with parallel vertical surfaces on both sides and an arc-shaped bottom. The mounting groove has a large space at the opening, which facilitates the insertion and installation of the rotating shaft. The vertical surfaces on both sides provide good guidance, which can guide the rotating shaft smoothly into the mounting groove, reducing the alignment difficulty during assembly. The arc-shaped bottom design can better fit the rotating shaft, allowing the rotating shaft to rotate smoothly and stably. The two side walls of the U-shaped opening structure can provide stable support, preventing the rotating shaft from shifting or shaking during installation, thereby improving the stability of the entire snap-fit ​​structure.

[0012] As an improvement, the housing is provided with a mounting part adapted to the buckle. The mounting part extends outward from the housing, and the mounting groove is located on the inner wall of the mounting part. In this technical solution, by providing a mounting part on the housing, the main function is to provide a stable mounting position for the buckle. The mounting part is a structure formed by extending outward from the housing, and it is integrated with the housing, reducing the number of parts. The design of the mounting part and the buckle are mutually compatible. The mounting part also provides limiting and guiding functions for the buckle, enhancing the stability of the overall structure. The mounting groove is located on the inner wall of the mounting part, ensuring that the buckle can be accurately installed and reliably fixed. The fit between the buckle and the mounting groove is tighter and more stable.

[0013] As an improvement, the other end of the buckle is connected to the rotating shaft via a beveled structure. The rotating shaft is higher than the other end of the buckle, so that a gap is formed between the other end of the buckle and the housing when the hook and the fastening part are connected. In this technical solution, the other end of the buckle is set to have a beveled structure with the rotating shaft, and the rotating shaft is higher than the other end of the buckle. This allows the other end of the buckle to naturally form a certain gap with the housing when it engages with the rotating shaft. The main function is to provide sufficient space for pressing and rotating the buckle. When the user presses the other end of the buckle, the other end of the buckle is rotated towards the housing, and the buckle can rotate around the rotating shaft. This causes the other end of the buckle to rotate in the opposite direction away from the housing, separating the hook and the fastening part. The existence of the gap avoids direct contact between the buckle and the housing, reduces friction and wear, and ensures smoother movement of the buckle.

[0014] As an improvement, a handle is rotatably mounted on the cover; the cover is provided with a receiving groove for accommodating the handle, the receiving groove being formed by an inward indentation of the cover. In this technical solution, the handle is mounted on the cover by a rotatable connection, allowing the handle to be folded or stored when not in use, and unfolded when needed. The receiving groove, formed by an inward indentation of the cover, is used to accommodate the handle, so that the handle can be flush with the surface of the cover or embedded inside the cover when stored, reducing the space occupied, while protecting the handle from external damage, making the toolbox more convenient to store and carry.

[0028] like Figures 1 to 8 As shown, this application discloses a toolbox, including a box body 1 and a cover 2 rotatably connected. The cover 2 can be rotatably opened or closed relative to the box body 1. It also includes a buckle 3. The side wall of the buckle 3 is provided with a rotating shaft 31. The box body 1 is provided with a mounting groove 11 adapted to the rotating shaft 31. The rotating shaft 31 is connected to the mounting groove 11 so that the buckle 3 is rotatably installed on the box body 1. The toolbox is composed of a box body 1 and a cover 2. The cover 2 is connected to the box body 1 by a rotatable connection, thereby realizing the action of opening or closing. The box body 1 and the cover 2 are connected by the buckle 3 to realize the closing and locking or unlocking. The buckle 3 is connected to the mounting groove 11 on the box body 1 through the rotating shaft 31, so that the buckle 3 can rotate around the rotating shaft 31. The mounting groove 11 does not require complex processing technology or high-precision processing equipment, which reduces the processing difficulty and cost in the production process.

[0029] One end of the buckle 3 is provided with a hook portion 32, and the cover 2 is provided with a fastening portion 21 that is adapted to the hook portion 32. When one end of the buckle 3 is subjected to force, the hook portion 32 rotates to connect with the fastening portion 21, and when the other end of the buckle 3 is subjected to force, the hook portion 32 rotates to disengage from the fastening portion 21. The hook portion 32 of the buckle 3 can flexibly rotate to connect with or disengage from the fastening portion 21 on the cover 2. The tight fit between the hook portion 32 and the fastening portion 21 can effectively prevent the toolbox from being accidentally opened during use. When the user presses... When the buckle 3 has one end with the hook part 32, the hook part 32 is connected to the fastening part 21 by force, realizing the closing and locking of the cover 2 and the box 1. The cover 2 cannot be rotated to open. When the user presses the other end of the buckle 3 away from the hook part 32, the buckle 3 is rotated by force, and the hook part 32 is disengaged from the fastening part 21 through the lever principle, realizing the closing and unlocking of the cover 2 and the box 1. The cover 2 can be rotated to open. The user can lock and unlock the cover 2 by simple pressing operation, which is simple and labor-saving.

[0030] On the other hand, traditional snap-fit ​​structures usually require springs to provide elastic force to achieve automatic reset of snap-fit ​​3 or enhance the stability of snap-fit. However, the snap-fit ​​3 provided in this application can achieve its function without relying on springs. Snap-fit ​​3 is connected to the mounting groove 11 on the box body 1 through a rotating shaft 31. The hook part 32 of snap-fit ​​3 rotates to connect or disengage with the fastening part 21 on the cover body 2. The movement of snap-fit ​​3 depends entirely on the rotation of the rotating shaft 31, which reduces the number and complexity of parts. The toolbox has very few parts, with only one snap-fit ​​3 connected to the box body 1 through the rotating shaft 31. No additional fasteners or complicated assembly steps are required. Assembly can be completed simply by installing snap-fit ​​3 on the box body 1, which simplifies the production assembly process.

[0031] More specifically, such as Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the housing 1 is provided with a limiting structure 12, and the buckle 3 is provided with a snap-fit ​​part 33 adapted to the limiting structure 12. The limiting structure 12 and the snap-fit ​​part 33 cooperate to limit the buckle 3 to be positioned on the housing 1. The limiting structure 12 on the housing 1 is designed to provide a fixed assembly position and motion constraint for the buckle 3. The snap-fit ​​part 33 is provided on the buckle 3. Through the cooperation of the snap-fit ​​part 33 and the limiting structure 12, the buckle 3 is further limited and installed on the housing 1 to prevent the buckle 3 from falling off and to install the rotating shaft 31 of the buckle 3. More reliable, the limiting structure 12 abuts against the snap-fit ​​part 33 to ensure that the buckle 3 will not easily shift or loosen after installation. The limiting structure 12 provides a clear assembly position for the buckle 3, ensuring that the buckle 3 can be quickly and accurately positioned during installation, reducing assembly errors. Preferably, the limiting structure 12 is in the shape of a boss, and the snap-fit ​​part 33 abuts against the boss-shaped limiting structure 12, thereby limiting the buckle 3 and preventing the buckle 3 from loosening or falling off under vibration or external force, thus improving the reliability of the buckle 3.

[0032] More specifically, such as Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, the end of the latching part 33 is semi-circular. When the latch 3 is rotated under force, the end of the latching part 33 abuts against the limiting structure 12 and rotates relative to the limiting structure 12. The semi-circular end of the latching part 33 allows for smoother rotation and abutment when it engages with the limiting structure 12. The curved surface design of the semi-circular structure reduces stress concentration at the contact point and lowers the risk of wear. When the latch 3 is rotated under force, the semi-circular end of the latching part 33 abuts against the limiting structure 12. This abutment is not a rigid collision, but rather a smooth relative movement achieved through the contact between the curved surface of the semi-circular end and the limiting structure 12. The design of the semi-circular end allows the latching part 33 to slide or roll along the contour of the limiting structure 12 during rotation. The rotation of the latch 3 is not restricted by the latching part 33, thereby achieving stable rotation and limiting functions.

[0033] More specifically, such as Figure 3 , Figure 4 , Figure 6 and Figure 8As shown, the locking part 33 is coaxially arranged with the rotating shaft 31. The locking part 33 cooperates with the limiting structure 12 to assist the rotation of the rotating shaft 31. The locking part 33 and the rotating shaft 31 are coaxially arranged, that is, the central axis of the locking part 33 coincides with the central axis of the rotating shaft 31, so that the movement of the locking part 33 and the rotation of the rotating shaft 31 are closely coupled. The two always maintain a consistent axial relationship during the movement. The cooperation between the locking part 33 and the limiting structure 12 not only plays a limiting role, but also assists the rotation of the rotating shaft 31. During the rotation of the rotating shaft 31, the locking part 33 also acts as a rotating shaft through its semi-circular end. The movement of the locking part 33 can be directly transmitted to the rotating shaft 31, making the rotation of the rotating shaft 31 more stable and smooth, reducing the need for additional guide or limiting components, and simplifying the overall structure.

[0034] More specifically, such as Figure 4 As shown, the buckle 3 is provided with reinforcing ribs 34 connected to the snap-fit ​​part 33. There are at least two reinforcing ribs 34. The reinforcing ribs 34 are directly connected to the snap-fit ​​part 33. Their function is to enhance the structural strength and rigidity of the snap-fit ​​part 33, so that the snap-fit ​​part 33 can remain stable when subjected to external forces, and reduce deformation or damage caused by local stress concentration. The provision of at least two reinforcing ribs 34, through the synergistic effect of multiple reinforcing ribs 34, distributes stress more evenly, further improving the overall strength and stability of the buckle 3. The design of multiple reinforcing ribs 34 can also be flexibly arranged according to the shape of the buckle 3 and the stress conditions, which can extend the service life of the product.

[0035] More specifically, such as Figure 3 and Figure 4 As shown, the end of the rotating shaft 31 is provided with a guide slope 311 adapted to the mounting groove 11. The rotating shaft 31 is inserted into the mounting groove 11 by cooperating with the mounting groove 11 through the guide slope 311. The end of the rotating shaft 31 is designed with a guide slope 311, the shape and angle of which are adapted to the entrance part of the mounting groove 11. The main purpose is to allow the rotating shaft 31 to enter the mounting groove 11 more smoothly through the guiding effect of the slope when it is inserted into the mounting groove 11, reducing friction and resistance during the insertion process. Through the guidance of the guide slope 311, the rotating shaft 31 can be more accurately positioned in the mounting groove 11, thereby improving the assembly accuracy of the entire snap-fit ​​structure 3. This matching method not only simplifies the assembly process, but also reduces the risk of component damage due to improper assembly.

[0036] More specifically, such as Figure 3As shown, the mounting groove 11 has a U-shaped opening structure. The mounting groove 11 adopts a U-shaped opening design, that is, the cross-section of the groove is "U" shaped, with parallel vertical surfaces on both sides and an arc-shaped bottom. The mounting groove 11 has a large space at the opening, which facilitates the insertion and installation of the rotating shaft 31. The vertical surfaces on both sides provide good guidance, which can guide the rotating shaft 31 smoothly into the mounting groove 11, reducing the difficulty of alignment during assembly. The arc-shaped bottom design can better fit the rotating shaft 31, so that the rotating shaft 31 can rotate smoothly and stably. The two side walls of the U-shaped opening structure can provide stable support, preventing the rotating shaft 31 from shifting or shaking during installation, thereby improving the stability of the entire snap-fit ​​structure 3.

[0037] More specifically, such as Figure 1 and Figure 3 As shown, the housing 1 is provided with a mounting part 13 that is adapted to the buckle 3. The mounting part 13 extends outward from the housing 1, and the mounting groove 11 is provided on the inner side wall of the mounting part 13. By providing the mounting part 13 on the housing 1, the main function is to provide a stable mounting position for the buckle 3. The mounting part 13 is a structure that extends outward from the housing 1. The mounting part 13 is integrated with the housing 1, which reduces the number of parts. The design of the mounting part 13 and the buckle 3 are mutually compatible. The mounting part 13 also provides limiting and guiding functions for the buckle 3, which enhances the stability of the overall structure. The mounting groove 11 is provided on the inner side wall of the mounting part 13 to ensure that the buckle 3 can be accurately installed and reliably fixed. The fit between the buckle 3 and the mounting groove 11 is tighter and more stable.

[0038] More specifically, such as Figure 4 , Figure 6 and Figure 8 As shown, the other end of the buckle 3 is connected to the rotating shaft 31 via an inclined structure 35. The rotating shaft 31 is higher than the other end of the buckle 3, so that when the hook part 32 is connected to the fastening part 21, a gap is formed between the other end of the buckle 3 and the box body 1. The inclined structure 35 between the other end of the buckle 3 and the rotating shaft 31, and the fact that the rotating shaft 31 is higher than the other end of the buckle 3, allows the other end of the buckle 3 to naturally form a certain gap with the box body 1 when it is engaged with the rotating shaft 31. The main function is to provide sufficient space for the pressing and rotation of the buckle 3. When the user applies force to press the other end of the buckle 3, the other end of the buckle 3 is forced to rotate towards the box body 1. The buckle 3 can rotate around the rotating shaft 31, thereby causing one end of the buckle 3 to rotate in the opposite direction away from the box body 1, separating the hook part 32 from the fastening part 21. The existence of the gap avoids direct contact between the buckle 3 and the box body 1, reduces friction and wear, and ensures smoother movement of the buckle 3.

[0039] More specifically, such as Figure 1As shown, a handle 4 is rotatably mounted on the cover 2. The handle 4 is mounted on the cover 2 by a rotatable connection, allowing the handle 4 to be folded or stored when not in use, and unfolded when needed. The cover 2 is provided with a receiving groove 22 for accommodating the handle 4. The receiving groove 22 is formed by the inward indentation of the cover 2, so that the handle 4 can be flush with the surface of the cover 2 or embedded in the interior of the cover 2 when stored, reducing the space occupied, while protecting the handle 4 from external damage, making the toolbox more convenient to store and carry.

[0040] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
