Description

Technical Field

[0001] The utility model relates to the technical field of electronic scales, in particular to a split-screen bracket structure for electronic scales. Background Art

[0002] Most electronic scales currently on the market use a single display stand with a fixed structure and no adjustment capabilities, making it difficult to meet the diverse needs of users in different environments. For example, at a supermarket checkout counter, cashiers may need to adjust the display's tilt or height to accommodate different heights or lighting conditions, reduce fatigue from prolonged fixed viewing angles, and achieve better visual quality or operational convenience. However, existing stand designs often fail to provide these necessary adjustments.

[0003] In addition, most electronic scales on the market use a single-screen design, which prevents consumers from obtaining relevant information intuitively; for merchants, the lack of intuitive display may lead to inconvenience in the payment process and may cause errors in the account.

[0004] In order to improve the user experience, it is necessary to introduce a split-screen design and develop a corresponding split-screen support structure to better meet the growing demand for consumer experience. Such a design can not only improve the visualization of information, but also optimize the operation process, bringing users a more convenient and efficient experience. Utility Model Content

[0005] The utility model aims to provide an electronic scale split-screen bracket with a stable structure, flexible adjustment, easy installation and strong adaptability, as well as an electronic scale using the bracket, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a split-screen electronic scale bracket structure, comprising a display screen hanging plate (for mounting the display screen), an angle adjustment plate, a vertical plate, a flat plate, an extension piece, and a locking mechanism;

[0007] The vertical plate and the flat plate are arranged vertically and are integrally formed;

[0008] The two ends of the upper part of the vertical plate are respectively connected to one end of the extension piece, and the other end of the extension piece is hinged to the angle adjustment plate through a locking mechanism; the locking mechanism is used to fix and adjust the angle of the display screen, which can not only meet the angle adjustment requirements of the display screen, but also prevent the hinge from loosening or rotating when in use, thereby ensuring the stability and reliability of the connection between the angle adjustment plate and the extension piece.

[0009] The angle adjustment plate is formed by stamping and bending the flat surface of the display panel, and the bend is stamped with double triangular ribs 7. Compared with conventional bracket structures without angle ribs or welded triangular ribs, the stamped double triangular rib bracket structure has higher structural strength and rigidity, better stability, stronger deformation resistance and lower manufacturing cost.

[0010] The angle adjustment plate is arranged in the middle of the display screen hanging plate; the vertical plate is vertically arranged in the middle of the flat plate, and is integrally formed to form a T-shaped structure.

[0011] The angle adjustment plates are respectively arranged on both sides of the display screen hanging board panel; the vertical plates are respectively arranged on both sides of the flat plate and are integrally formed to form a U-shaped structure.

[0012] The extension piece is fixedly connected to the vertical plate connection end and is formed as one piece.

[0013] The extension piece is detachably connected to the vertical plate connection end.

[0014] The extension piece is hinged to the vertical plate connecting end through a locking mechanism.

[0015] The locking mechanism includes an anti-rotation bolt, a butterfly spring, an anti-rotation washer, and a locking nut. The anti-rotation bolt passes through an extension, an angle adjustment plate, an anti-rotation washer, two butterfly springs with opposing convex surfaces, and an anti-rotation washer, before connecting to the locking nut. The display panel 1, integrally formed with the angle adjustment plate, can rotate about the anti-rotation bolt under external force. After rotating to a certain angle, the elastic force of the butterfly spring generates friction between the angle adjustment plate and the display panel, causing the display panel to self-lock.

[0016] The anti-rotation bolt 6-3 has a rectangular screw rod, and the inner holes of the anti-rotation washer 6-3 and the extension member 5 are rectangular holes that match the rectangular screw rod. When the display screen is locked, only the angle adjustment plate 2 rotates about the anti-rotation bolt 6-3. The extension member 5, constrained by the shape of the inner hole, does not rotate with the angle adjustment plate 2. This reduces resistance to adjusting the display screen angle and effectively prevents the bolt from loosening under vibration or load, increasing the stability and security of the connection.

[0017] The hinged end of the angle adjustment plate features an arc-shaped retaining slot, while the hinged end of the extension piece and the angle adjustment plate features a retaining portion that fits into the arc-shaped retaining slot. These two components work together to define the display's adjustable angle range, enhancing user convenience while preventing potential hazards such as excessive external force or locking mechanism failure, ensuring the stability and safety of the display stand.

[0018] The display screen hanging plate panel is provided with split screen mounting holes and positioning holes for mounting the display screen; the flat panel panel is provided with column mounting holes and positioning holes for mounting the electronic scale column.

[0019] A split-screen electronic scale, characterized in that the split-screen electronic scale includes the above-mentioned electronic scale split-screen bracket structure.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The split-screen display design allows both customers and cashiers to see sales data, effectively avoiding accounting errors and other problems. The angle and height of the display can be flexibly adjusted according to the height of the cashier or the table, enhancing flexibility and optimizing the visual experience.

[0022] 2. Strengthened bracket structure. The double triangular ribs formed by stamping significantly enhance the bracket's strength and durability, reduce the risk of fracture, and ensure weighing accuracy and overall bracket stability. This overcomes the weaknesses of traditional brackets, such as weak bends and insufficient strength.

[0023] 3. Material savings and efficient manufacturing. The angle adjustment plate is formed by stamping and bending the display panel's flat surface, achieving full material utilization and lightweight design. Furthermore, the angle adjustment plate and corner ribs can be stamped and formed in one go, saving production time and improving efficiency.

[0024] 4. The double-hinged connection and locking mechanism further improve the flexible adjustment of the angle, height and fixed position of the display screen, expand the scope of use, and make user operation and information viewing more comfortable and convenient.

[0025] 5. The detachable extension design makes it easy to replace extensions of different lengths or angles to meet the needs of different occasions, and is also conducive to the maintenance and replacement of components, reducing maintenance costs and extending the service life of the bracket.

[0035] The specific implementation of the present utility model is described in detail below with reference to the accompanying drawings and examples.

[0036] Example 1 (see Figures 1-2 )

[0037] An electronic scale support structure includes a display screen hanging plate 1, an angle adjustment plate 2, a vertical plate 3, a flat plate 4, an extension member 5 and a locking mechanism 6, wherein:

[0038] The display screen hanging plate 1 is used to install the display screen and provide a stable support.

[0039] The angle adjustment plates 2 are arranged on both sides of the display screen hanging plate panel 1 and are formed by stamping and bending the flat surface of the display screen hanging plate 1. The angle adjustment plates 2 are hinged to the extension member 5 through a locking mechanism 6 and are used to adjust the angle of the display screen.

[0040] The extension piece 5 is used to extend or expand the installation position of the display screen to facilitate the installation and adjustment of display screens of different sizes or structures.

[0041] The vertical plate 3 and the flat plate 4 are arranged vertically and formed integrally to form a U-shaped structure. This design not only improves the load-bearing capacity of the bracket, but also reduces the risk of deformation or damage caused by external forces, while saving materials and reducing weight.

[0042] The upper ends of the vertical plate 3 are detachably connected to the connecting ends of the extension piece 5, respectively, for dual-screen installation. Extension pieces of different lengths or angles can be replaced as needed (e.g., to increase the spacing between the two screens), improving the adaptability and flexibility of the bracket structure, facilitating bracket repair and replacement, extending the bracket's service life, and reducing maintenance costs.

[0043] The locking mechanism 6 is used for adjusting the angle of the display screen. It can achieve self-locking through the elastic force of the elastic member and effectively fix the display screen. It ensures the stability and reliability of the connection between the angle adjustment plate and the extension member. The locking mechanism 6 includes an anti-rotation bolt 6-1, a butterfly spring 6-2, an anti-rotation washer 6-3, and a locking nut 6-4. The anti-rotation bolt 6-1 passes through the extension member 5, the angle adjustment plate 2, an anti-rotation washer 6-3, two butterfly springs 6-2 with convex surfaces connected, and an anti-rotation washer 6-3 in sequence, and is then connected to the locking nut. Among them, the elastic force of the butterfly spring 6-2 with convex surfaces connected is more stable and reliable than the butterfly spring with concave surfaces connected. Because the concave surface is narrow, it is easy to misalign, resulting in small deformation of the butterfly spring and reduced elastic force; while the convex surface is connected because the butterfly spring aperture is adapted to the bolt rod, no misalignment will occur, the elastic force remains unchanged, and the friction between the extension member 5 and the angle adjustment plate 2 is constant. As a result, the convex surfaces of the butterfly spring can evenly distribute stress when subjected to force, reducing local stress concentration, extending the service life of the butterfly spring, and ensuring reliable and stable adjustment and fixation of the display screen.

[0044] Example 2

[0045] See also Figure 3 In this embodiment, the angle adjustment plate 2 is positioned in the center of the display panel 1; the vertical plate 3 is vertically positioned in the center of the flat plate 4, forming a one-piece T-shaped structure. Compared to the previous embodiment, this has a simpler structure, fewer components, and less material, making it particularly suitable for lightweight split-screen electronic scales.

[0046] Example 3

[0047] See also Figures 1 to 7 The angle adjustment plate 2 in this embodiment is formed by flat stamping and bending the display screen hanging plate 1 into one piece. A triangular recess 7-1 is provided at the outer corner of the bend, and a triangular convex rib 7-2 is provided at the corresponding inner corner of the bend. This structure can be stamped into a double triangular rib 7 at the bend by a stamping process. Compared with the traditional bracket structure without ribs or with welded right-angle ribs, the double triangular rib structure in this embodiment has the following advantages: 1. The right-angle rib is usually composed of a single right-angle triangle, with a small support surface (few support points), which limits its bearing capacity and rigidity. The double triangular rib is composed of two connected triangles, with a large support surface (many support points) and excellent strength and rigidity. This structural advantage makes the double triangular rib more stable and can effectively resist external forces and deformation. 2. The stress distribution of the right-angle rib is concentrated, especially at the right angle, where the stress is large, which can easily cause structural damage. The double triangular rib has the characteristics of a large bottom surface and a small convex surface. The cross-section at the right angle is particularly large, which can effectively disperse stress and maintain the integrity and stability of the structure. 3. Conventional welded right-angle rib brackets use a lot of materials, have complex processes, and are expensive to manufacture. However, the double triangular ribs and the bracket angle plate in this embodiment are formed in a single stamping process, which is highly efficient and low-cost.

[0048] Example 4

[0049] See also Figure 4 In this embodiment, the extension member 5 is fixedly connected to the connecting end of the upright 3, forming an integral, indivisible unit. This not only improves the strength and stability of the structure and prevents loosening at the connection, but also ensures the spacing between the sub-screens, facilitating quick and easy installation. It also reduces the number of connecting parts, resulting in a simple and compact structure and lowering manufacturing costs.

[0050] Example 5

[0051] See also Figure 5 In this embodiment, the ends of the extension member 5 are hinged to the vertical plate 3 and the angle adjustment plate 2 respectively through a locking mechanism 6. This double-hinged structure not only allows the display screen angle to be adjusted, but also the display screen height to be adjusted, further expanding the application range of the display screen. This overcomes the defect that the vertical pole connecting the electronic scale platform and the display screen is fixed in length and cannot be raised or lowered. (Often, due to different heights of people or work desks, this can only be solved by raising the legs or the table top, which is a poor user experience.)

[0052] Example 6

[0053] See also Figure 7 , The hinge end of the angle adjustment plate 2 of this embodiment is provided with an arc-shaped limiting slot 2-1, which is used to limit the adjustable angle range of the display screen. Correspondingly, the hinge end position of the extension piece 5 and the angle adjustment plate 2 is provided with a limiting portion 5-1 that can be embedded in the arc-shaped limiting slot 2-1. Through the cooperation between the arc-shaped limiting slot 2-1 and the limiting portion 5-1, it is ensured that the adjustment angle of the display screen is always maintained within the user's visual range. The user can easily adjust the angle of the display screen according to actual viewing needs to achieve the best visual experience, and the operation is simple and worry-free. In addition, the design also effectively limits the adjustment range of the display screen, prevents the display screen from accidentally rotating due to external forces, and enhances the stability of the entire structure. More importantly, the design also prevents the display screen from hanging upside down due to possible failure of the locking mechanism (such as insufficient spring locking force or butterfly spring failure), thereby eliminating potential safety hazards and improving the safety performance of the product.

[0054] Example 7

[0055] See also Figure 2 、 Figure 4 The anti-rotation bolt 6-3 has a rectangular rod, while the inner holes of the anti-rotation washer 6-3 and the extension 5 are rectangular holes that match the rectangular rod. This design ensures that when the display angle is adjusted in the locked state, only the angle adjustment plate 2 can rotate around the anti-rotation bolt 6-3. The extension 5, with its inner hole shape matching the rectangular screw, is restricted from rotating along with the angle adjustment plate 2. This reduces resistance when adjusting the display angle and effectively prevents the bolt from loosening under vibration or load, greatly enhancing the stability and security of the connection.

[0056] Electronic scale display angle adjustment process and self-locking principle

[0057] Adjustment process:

[0058] When the user needs to adjust the angle of the display screen, a sufficiently large external force (such as manual rotation) is applied to the display screen on the hanging plate to overcome the friction force generated by the butterfly spring, causing the display screen to start rotating around the anti-rotation bolt.

[0059] As the display rotates, the relative position between the angle adjustment plate and the extension plate changes. This process involves not only a change in the angle between the angle adjustment plate and the extension plate, but also potentially slight movement in the axial direction (i.e., perpendicular to the axis of rotation). Although the locking nut secures the rotating bolt, preventing significant axial movement, this relative axial change between the angle adjustment plate and the extension plate can still affect the degree of compression of the butterfly spring, resulting in subtle adjustments in the spring's elastic force.

[0060] The user needs to continue applying external force until the display is rotated to the desired angle. During this process, the direction of the friction force will continuously change as the display rotates. While the magnitude of the friction force (i.e., the amount of force resisting further rotation) may be affected by slight changes in the degree of compression of the butterfly spring, in most cases, this change is minimal and insufficient to significantly affect the stability of the display.

[0061] Self-locking process:

[0062] Once the hanging plate is rotated to the desired position and external force is removed, the butterfly spring, due to its inherent elastic force, attempts to lock the display in place through friction. The magnitude and direction of this friction are primarily determined by the butterfly spring's degree of compression and the contact angle. Although there may be slight variations in the butterfly spring's degree of compression during adjustment, once the display stops rotating, the butterfly spring strives to maintain its current compression state and lock the display in the desired position through steady friction. This allows the display to maintain a stable position when no external forces are acting on it (e.g., when it is only under its own weight).

[0063] This design ensures that the display screen can be flexibly adjusted in angle and also ensures its stability after adjustment.
