Description

Technical Field

[0001] This utility model relates to a hand-raising mechanism, specifically to a hand-raising structure and a product having the hand-raising structure. Background Technology

[0002] Raise-and-lower mechanisms are widely used in the chassis and other equipment of electronic products, typically for opening and closing covers, panels, or other components. Existing raise-and-lower mechanisms usually use springs as the reset and load-bearing elements to ensure smooth operation. However, existing raise-and-lower mechanisms have some significant problems in practical use, mainly in the following aspects:

[0003] First, assembling the springs is quite difficult. In traditional handle-raising mechanisms, the springs typically need to be precisely assembled into specific positions on either the moving or fixed parts of the handle. This assembly process is cumbersome and requires high precision. This not only increases the complexity of the production process but also makes it prone to defects during assembly, leading to a decline in product quality.

[0004] Secondly, the structure has poor reliability. Because the spring is fixed in a relatively simple way within the handle-raising structure, the stress point of the spring is often concentrated in a small area, making it prone to detachment or failure during use, thus affecting the functional stability of the entire handle-raising structure. This risk of spring detachment increases further under high-frequency operation or prolonged use, reducing the overall reliability of the product.

[0005] Secondly, the overall assembly process of the handle-raising structure is complex. When installing the existing handle-raising structure onto external products, the special position of the spring and the limitation of assembly space make the assembly process difficult and require more auxiliary tools or assembly steps, which increases production costs and time.

[0006] For example, prior art document CN202120143967.0 discloses a handle-raising structure and a chassis having the handle-raising structure. In this structure, the force-bearing end of the movable handle uses the left and right straight edges of a torsion spring that engage with slots in the movable handle to bear force, while the U-shaped portion of a torsion spring on the fixed handle engages with a slot in the fixed handle to bear force. Although this structure can achieve the handle-raising function to a certain extent, it still suffers from problems such as difficulty in spring assembly, insufficient structural reliability, and complex overall assembly during assembly, failing to meet the requirements of efficient assembly and long-term stable use.

[0007] In summary, the aforementioned problems in the existing technology limit the widespread application of the lifting mechanism. Therefore, there is an urgent need for a new lifting mechanism that can simplify the spring assembly process, improve the reliability of the structure, and be more easily installed into external products. Summary of the Invention

[0008] To address the aforementioned issues, this utility model provides a lifting arm structure and a product incorporating the lifting arm structure, which simplifies the spring assembly process, improves structural reliability, and facilitates easier installation into external products.

[0009] This utility model is achieved through the following technical solution: a hand-raising structure, comprising:

[0010] A handle fixing part is fixedly installed on the external product;

[0011] The movable part for raising the hand is elastically hinged to the fixed part for raising the hand; two hinge shafts are provided on the side of the movable part for raising the hand opposite to the fixed part for raising the hand, and torsion springs are installed on the two hinge shafts;

[0012] The U-shaped part of the torsion spring is pressed into the U-shaped groove on the arm-raising movable part, and the straight edges of the left and right sides of the torsion spring are inserted into the limiting grooves of the arm-raising fixed part for limiting.

[0013] As a preferred technical solution, the bottom surface of the limiting groove is provided with a limiting insertion hole, and the straight edge sections of the left and right sides of the torsion spring are inserted into the limiting insertion hole.

[0014] As a preferred technical solution, the hand-raising fixing part is provided with an avoidance groove on one side of the U-shaped part;

[0015] A limiting protrusion is formed inside the U-shaped groove, and the U-shaped part of the torsion spring is fastened to the outside of the limiting protrusion.

[0016] As a preferred technical solution, the lifting arm movable part is provided with an extension connection part relative to each hinge shaft, and the extension connection part is fixedly connected to the hinge shaft.

[0017] As a preferred technical solution, the lifting and moving part has a grasping part, and the grasping part has at least two hand-holding points.

[0018] As a preferred technical solution, a mounting portion is formed on one side of the opposite face of the hinge shaft, and a stepped surface is formed between the mounting portion and the hinge shaft. The two sides of the torsion spring are respectively fitted onto the mounting portion.

[0019] As a preferred technical solution, the lifting arm fixing part is provided with fixing holes, and the lifting arm fixing part is installed in the fixing holes by fasteners to complete the fixing of the lifting arm fixing part and the product.

[0020] The present invention provides a product comprising a product body and a lifting arm structure, wherein the lifting arm structure is installed at any position on the product body.

[0021] The beneficial effects of this utility model are: by improving the spring assembly method in the lifting mechanism, this utility model makes the spring installation simpler, significantly reduces the spring assembly time, and at the same time reduces the risk of adverse events during the assembly process, thus ensuring the production efficiency and quality of the product.

[0022] By pressing the U-shaped part of the spring directly into the U-shaped groove of the lower arm lifting mechanism, the spring can be more firmly fixed to the arm lifting mechanism, which greatly improves the stability and reliability of the entire arm lifting structure and avoids the risk of the spring falling off due to uneven force or long-term use during use.

[0023] In addition, the lifting and fixing part is fastened into the limiting groove by the left and right straight edges of the torsion spring, which makes the overall assembly of the product smoother. Especially when installing external products, it not only reduces the assembly difficulty, but also improves the integration and appearance consistency of the overall product.

[0031] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0032] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0033] like Figures 1-3 As shown, a lifting arm structure of this utility model includes a lifting arm fixing part, which is fixedly installed on an external product. The external product can be any kind of product, such as a box. The lifting arm structure can be used to lift the box.

[0034] It also includes a lifting arm movable part, which is elastically hinged to the lifting arm fixed part; the lifting arm movable part is provided with two hinge shafts on one side opposite to the lifting arm fixed part, and torsion springs are installed on the two hinge shafts;

[0035] The U-shaped part of the torsion spring is pressed into the U-shaped groove on the lifting arm movable part, which can effectively improve the structural reliability and reduce the risk of the spring falling off. The straight edge sections 14 on the left and right sides of the torsion spring are inserted into the limiting groove of the lifting arm fixing part, which makes it easier to install the product into the lifting arm.

[0036] The bottom surface of the limiting groove is provided with a limiting insertion hole, and the straight edges of the left and right sides of the torsion spring are inserted into the limiting insertion hole.

[0037] Among them, such as Figure 1 and Figure 2 As shown, the lifting arm fixing part is provided with an avoidance groove on one side of the U-shaped part, and the U-shaped part can be snapped into the U-shaped groove of the lifting arm movable part from the avoidance groove;

[0038] A limiting protrusion is formed inside the U-shaped groove. The U-shaped part of the torsion spring is fastened to the outside of the limiting protrusion. The limiting protrusion restricts the U-shaped part of the torsion spring, thereby realizing the torsional force on the torsion spring and ultimately achieving elastic reset.

[0039] In this embodiment, the lifting arm movable part is provided with an extension connection part relative to each hinge shaft. The extension connection parts are fixedly connected to the hinge shaft. When the lifting arm movable part is opened relative to the lifting arm fixed part, the torsion spring can be twisted. The torsion spring is twisted under force and produces elastic deformation, thereby achieving the purpose of lifting the arm.

[0040] The lifting arm has a gripping part with at least two hand-holding points, which is more in line with ergonomics. When needed, the user only needs to open the lifting arm by holding the hand-holding points to lift the product.

[0041] like Figure 2 As shown, a mounting part is formed on one side of the opposite face of the hinge shaft. A stepped surface is formed between the mounting part and the hinge shaft. The two sides of the torsion spring are respectively fitted on the mounting part. When the hinge shaft rotates, the two sides of the torsion spring are restricted, and elastic torsion can occur. After the lifting force is removed, the lifting movable part can be reset.

[0042] To facilitate the fixed installation of the hand-raising fixing part, in this embodiment, the hand-raising fixing part is provided with fixing holes, and the hand-raising fixing part is installed in the fixing holes by fasteners to complete the fixed installation of the hand-raising fixing part and the product.

[0043] The present invention provides a product comprising a product body and a lifting arm structure, wherein the lifting arm structure is installed at any position on the product body.

[0044] This utility model improves the spring assembly method in the lifting mechanism, making spring installation simpler, significantly reducing spring assembly time, and reducing the risk of defects during assembly, thus ensuring product production efficiency and quality.

[0045] By pressing the U-shaped part of the spring directly into the U-shaped groove of the lower arm lifting mechanism, the spring can be more firmly fixed to the arm lifting mechanism, which greatly improves the stability and reliability of the entire arm lifting structure and avoids the risk of the spring falling off due to uneven force or long-term use during use.

[0046] In addition, the lifting and fixing part is fastened into the limiting insertion hole 15 in the limiting groove by the left and right straight edges of the torsion spring, which makes the overall assembly of the product smoother, effectively prevents the straight edge 14 from loosening, and has a better positioning effect. When installing external products, it not only reduces the assembly difficulty, but also improves the overall integration and appearance consistency of the product.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
