[0002] A toolbox is a container used to organize and store various tools. Its main function is to categorize and store tools, making them easy to find, access, and store. To enhance storage capacity, the top and bottom lids of toolboxes can be designed with various compartments for storing tool parts, etc.
[0003] However, the current toolbox lid cannot be fixed at any angle after being opened. When users open the toolbox lid normally, they will release it after rotating it about 120°. The lid will fall due to inertia, causing it to fall off and be damaged. If precision instruments are fixed inside the lid, it will also be damaged. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a tool box to solve the problem that the tool box lid is easily dropped and damaged after being opened.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A tool box includes an upper cover and a lower cover, a rotating shaft is hinged between the upper cover and the lower cover, and a damping ring is provided on the rotating shaft for contacting the upper cover and the lower cover to increase the rotational friction of the rotating shaft.
[0006] Compared with existing technologies, the above technical solutions have the following beneficial effects:
[0007] By attaching a damping ring to the rotating shaft, which contacts both the top and bottom covers simultaneously, the friction of the rotating shaft is increased. This friction overcomes the rotation of the top cover due to gravity and inertia after release, preventing the top cover from breaking. Furthermore, by using different damping rings to adjust the friction, the top cover can be suspended at any angle after being opened and released, greatly enhancing the user experience and aesthetics of the product.
[0008] Based on the above technical solution, the embodiments of this application can be further improved as follows:
[0009] In one embodiment, the damping ring is interference-fitted onto the rotating shaft, and the two sides of the damping ring are respectively interference-fitted with the upper cover and the lower cover.
[0010] In one embodiment, the upper cover or the lower cover has an assembly groove, and the outer peripheral surface of the damping ring is interference-fitted into the assembly groove.
[0011] In one embodiment, the damping ring is an elastic damping ring.
[0012] In one embodiment, the rotating shaft includes:
[0013] A pin, one end of which is fitted into the upper cover and the other end of which is fitted into the lower cover;
[0014] An elastic element abuts between the pin and the upper cover, or between the pin and the lower cover.
[0015] In one embodiment, an annular groove for accommodating the elastic element is provided on either end of the pin.
[0016] In one embodiment, a first connecting portion is provided on one side of the upper cover, and a second connecting portion is provided on one side of the lower cover corresponding to both ends of the first connecting portion. The rotating shaft is disposed between the first connecting portion and the second connecting portion, and the rotating shaft is disposed on the first connecting portion on the side away from the outer surface of the upper cover.
[0017] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0018] 1. By attaching a damping ring to the rotating shaft between the upper and lower covers, the friction between the upper and lower covers during rotation is increased. This prevents the upper cover from falling freely after it is opened due to friction, thus avoiding damage to the upper cover.
[0019] 2. By setting the rotating shaft to be a combination of a pin and an elastic element, the rotating shaft becomes a telescopic shaft, which can be installed by simply pressing it, making it more convenient. Attached Figure Description

[0033] Example
[0034] like Figure 1-4As shown, the toolbox provided by this utility model includes an upper cover 1 and a lower cover 2. A rotating shaft 3 is hinged between the upper cover 1 and the lower cover 2. The rotating shaft 3 is hinged to one side of the upper cover 1 and the lower cover 2. Both the upper cover 1 and the lower cover 2 are provided with compartments for placing tools such as screws. The rotating shaft 3 is provided with a damping ring 4 for contacting the upper cover 1 and the lower cover 2 to increase the rotational friction of the rotating shaft 3, so that the upper cover 1 and the lower cover 2 have a more obstructive feeling when rotating around the rotating shaft 3.
[0035] By attaching a damping ring 4 to the rotating shaft 3, the damping ring 4 contacts both the upper cover 1 and the lower cover 2 simultaneously, thereby increasing the friction of the rotating shaft 3. This friction can overcome the rotation of the upper cover 1 due to gravity and inertia after release, preventing the upper cover 1 from breaking. In addition, by using different damping rings 4, the magnitude of the friction can be adjusted, allowing the upper cover 1 to hover at any angle after being opened and released, greatly improving the user experience and aesthetics of the product.
[0036] Specifically, the damping ring 4 is interference-fitted onto the rotating shaft 3, preventing smooth rotation between the damping ring 4 and the rotating shaft 3. Simultaneously, the two sides of the damping ring 4 are interference-fitted with the upper cover 1 and the lower cover 2, respectively, meaning the upper cover 1 and the lower cover 2 abut against the two end faces of the damping ring 4. The damping ring 4 prevents smooth rotation between the upper cover 1 and the lower cover 2. Through this interference fit, and utilizing the friction between the damping ring 4 and the rotating shaft 3 and the upper cover 1 and the lower cover 2, the angle between the upper cover 1 and the lower cover 2 can be fixed at the position after release, achieving stepless rotation.
[0037] like Figure 4 As shown, in order to increase the friction between the damping ring 4 and the upper cover 1 or the lower cover 2, an assembly groove 5 is provided on the upper cover 1 or the lower cover 2. The outer peripheral surface of the damping ring 4 is interference-fitted into the assembly groove 5. In this embodiment, by providing an assembly groove 5 on the upper cover 1, the outer peripheral surface of the damping ring 4 is interference-fitted with the inner wall surface of the assembly groove 5, which increases the contact area between the damping ring 4 and the upper cover 1, increases the friction, makes full use of the outer peripheral surface of the damping ring 4, and at the same time serves to fix the damping ring 4.
[0038] In this embodiment, the damping ring 4 is an elastic damping ring 4. The elasticity of the damping ring 4 allows the outer surface of the damping ring 4 to apply a certain pressure to contact the upper cover 1, the lower cover 2 and the rotating shaft 3, thereby achieving an interference fit and increasing the friction. In addition, the outer surface of the elastic damping ring 4 has an anti-slip and wear-resistant layer, which increases the friction while also providing wear resistance.
[0039] To achieve rapid assembly and simplify the assembly process, in this embodiment, the rotating shaft 3 is configured to include a pin 301 and an elastic element 302, wherein the elastic element 302 can be implemented using a spring.
[0040] One end of the pin 301 is fitted into the upper cover 1, and the other end is fitted into the lower cover 2. Specifically, blind holes 8 for assembly are provided at the positions of the upper cover 1 and the lower cover 2 for engaging with the ends of the pin 301, so that both ends of the pin 301 are respectively fitted into them.
[0041] The elastic element 302 abuts between the pin 301 and the upper cover 1, or between the pin 301 and the lower cover 2. In this embodiment, the elastic element 302 abuts between the blind hole 8 on the upper cover 1 and the end of the pin 301. During assembly, the pin 301 is pressed towards the elastic element 302 to press the pin 301 into the blind hole 8. Then, the blind hole 8 on the lower cover 2 is aligned with the other end of the pin 301 away from the elastic element 302. After releasing, the elastic force of the elastic element 302 pushes the other end of the pin 301 into the blind hole 8 of the lower cover 2. Using this rotating shaft 3 simplifies the mold and the assembly process, and also makes the product more stable.
[0042] To ensure the connection stability of the elastic element 302, an annular groove 303 is provided on either end of the pin 301 to accommodate the elastic element 302. One end of the elastic element 302 abuts in the annular groove 303, and the other end abuts in the blind hole 8. The annular groove 303 can partially cover one end of the elastic element 302, which plays a limiting role and facilitates assembly.
[0043] Furthermore, the annular groove 303 is configured as an annular structure that is wider on the outside and narrower on the inside. When one end of the elastic member 302 is inserted into it to a certain depth, the inner wall of the gradually narrowing annular groove 303 clamps one end of the elastic member 302, preventing the elastic member 302 from falling out of the pin 301, which makes it easier to assemble the rotating shaft 3.
[0044] The upper cover 1 has a first connecting part 6 on one side. The first connecting part 6 extends outward in any direction from the side of the upper cover 1. In this embodiment, it extends along the direction perpendicular to the plane of the upper cover 1 to form a long strip-shaped first connecting part 6 integrally formed on the side of the upper cover 1.
[0045] like Figure 3As shown, a second connecting part 7 is provided on one side of the lower cover 2 corresponding to both ends of the first connecting part 6. The second connecting part 7 is located at both ends of the first connecting part 6. The blind hole 8 is located on the opposite surface of the two ends of the first connecting part 6 and the two outer sides of the second connecting part 7. The rotating shaft is located between the first connecting part 6 and the second connecting part 7. The rotating shaft is located on the side of the first connecting part 6 away from the outer surface of the upper cover 1. Since the rotating shaft is located at the end of the first connecting part 6, the outer surface of the upper cover 1 is the side away from the compartment for placing parts. When the upper cover 1 rotates around the rotating shaft 3 to form 180° with the lower cover 2, the outer surface of the upper cover 1 contacts the table, lifting the rotating shaft 3 on the first connecting part 6, and then lifting the side of the lower cover 2 connected to it, so that the lower cover 2 tilts at a certain angle. This angle can be formed at 5-15° depending on the actual situation, which makes it more convenient to display and greatly improves the user experience and sense of form.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
