Description

Technical Field

[0001] This utility model belongs to the field of electronic scale technology, specifically relating to a flipping and slow-release mechanism. Background Technology

[0002] An electronic scale is a type of weighing instrument. Weighing instruments are tools that use Hooke's Law or the lever balance principle of forces to determine the mass of objects. Based on their structural principles, they can be divided into three main categories: mechanical scales, electronic scales, and electromechanical scales. An electronic scale mainly consists of three parts: a load-bearing system, a force transmission and conversion system, and a display system.

[0003] Some existing scales are also used in the medical industry, especially for patients with mobility impairments who need to be propelled in wheelchairs. These patients are unable to move on their own and need to use a wheelchair to get on the scale. Many current scales use ramps for getting on and off, but wheelchairs with ramps do not have any protective measures for the ramps. The heavy weight of the ramps and the lack of cushioning can cause them to fall directly, which may cause impact to the user's hands. Therefore, a flipping and slow-release mechanism is proposed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given the following technical problems in the existing technology: how to design a slope protection brick that can be fixed and connected to each other through splicing, so as to form an overall stable structure and adapt to the complex changes in the natural environment.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flipping slow-release mechanism, including a scale body, with rotating shafts installed on both the front and rear sides of the scale body, rotating sleeves installed on the outer side of the rotating shafts, bearings installed on the outer side of the rotating sleeves, bushings installed on the rotating shafts, dampers installed on the outer side of the bushings, connecting plates installed at the ends of the two rotating shafts that protrude from the scale body, the same slope protection installed on the two connecting plates, and a limit plate connected to the damper.

[0007] Furthermore, the rotating shaft is rotatably connected to the scale body via bearings.

[0008] By adopting the above technical solution, the smooth rotation of the shaft and the scale body is ensured through the bearing configuration.

[0009] Furthermore, a protective sleeve fitted over the outside of the bearing is installed between the connecting plate and the outer side of the scale body.

[0010] By adopting the above technical solution, wear is reduced through the installation of a protective sleeve.

[0011] Furthermore, the end of the rotating shaft away from the connecting plate is provided with a thread, and a nut is connected to the thread.

[0012] By adopting the above technical solution, the nut is used to restrict the rotation shaft to one end, ensuring the overall structure is secure and the operation is stable.

[0013] Furthermore, a connecting seat one is fixedly connected to the rotating shaft between the bearing and the damper, a base is provided on the damper, a connecting seat two is installed on the rotating shaft of the damper, and the limiting plate is connected to the connecting seat two.

[0014] By adopting the above technical solution, the base is connected to the connecting seat one, which in turn connects to the damper. The limiting plate is connected to the connecting seat two, ensuring the operation of the overall function. When the slope is rotated, when it reaches a certain position, that is, when the limiting plate contacts the side wall of the scale body, the rotation is restricted. At this time, under the action of the damper, the slope will not fall quickly, preventing accidental injury to the user's hand. Then, force is applied to the slope, which will exceed the limiting capacity of the damper, causing the slope to drive the rotation of the shaft and then fall slowly, ensuring stability.

[0015] Furthermore, both the connecting seat and the base are provided with several matching screw holes, and bolts passing through the connecting seat and the base are installed in the screw holes.

[0016] By adopting the above technical solution, the connecting seat can be stably connected to the base using bolts.

[0017] Furthermore, both the connecting seat 2 and the limiting piece are provided with several matching screw holes 2, and bolts 2 that pass through the connecting seat 2 and the limiting piece are installed in the screw holes 2.

[0018] By adopting the above technical solution, the connecting seat two and the limiting plate are fastened by using bolt two through the screw hole two of the connecting seat two and the limiting plate.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model prevents the slope from rotating further when the limiting plate contacts the side wall of the scale body, thus preventing the slope from falling rapidly and injuring the user. This avoids safety hazards caused by rapid falling and ensures operational safety. Then, applying an external force will allow the slope to descend slowly.

[0021] 2. This utility model can be unfolded via the slope protection for easy access to and from the weighing platform, and can also be folded up to reduce space occupation. Through the cooperation of the damper and the limiting plate, the folding process can be controlled and buffered, reducing the difficulty of operation and improving the user experience.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0033] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0034] Reference Figures 1-5 This utility model embodiment proposes a flipping slow-release mechanism, including a scale body 1. A rotating shaft 3 is installed on both the front and rear sides of the scale body 1. A rotating sleeve 9 is installed on the outer side of the rotating shaft 3. A bearing 2 is installed on the outer side of the rotating sleeve 9. A bushing 8 is installed on the rotating shaft 3. A damper 4 is installed on the outer side of the bushing 8. A connecting plate 10 is installed on one end of each of the two rotating shafts 3 that protrudes from the scale body 1. The same slope protection 6 is installed on the two connecting plates 10. A limit plate 7 is connected to the damper 4.

[0035] The rotating shaft 3 is rotatably connected to the scale body 1 through the bearing 2. The bearing 2 ensures that the rotating shaft 3 and the scale body 1 rotate smoothly.

[0036] A protective sleeve 5 is installed between the connecting plate 10 and the outer side of the scale body 1, which is fitted onto the outside of the bearing 2. The protective sleeve 5 reduces wear.

[0037] The end of the rotating shaft 3 away from the connecting plate 10 is provided with a thread, and a nut is connected to the thread. The nut restricts the rotating shaft 3 to one end, ensuring the overall structure is tight and the operation is stable.

[0038] A connecting seat 42 is fixedly connected to the rotating shaft 3 between the bearing 2 and the damper 4. The damper 4 is equipped with a base 41, and a connecting seat 43 is installed on the rotating shaft of the damper 4. The limiting plate 7 is connected to the connecting seat 43. The connecting seat 42 connects to the base 41, and then to the damper 4. The connecting seat 43 connects to the limiting plate 7 to ensure the operation of the overall function. When the slope 6 is rotated, when it reaches a certain position, that is, when the limiting plate 7 contacts the side wall of the scale body 1, the rotation is restricted. At this time, under the action of the damper 4, the slope 6 will not fall quickly, preventing accidental injury to the user's hand. Then, force is applied to the slope 6, which will exceed the limiting capacity of the damper 4, causing the slope 6 to drive the rotation of the rotating shaft 3 and then fall slowly to ensure stability.

[0039] Both the connector 42 and the base 41 are provided with several matching screw holes. The screw holes are used to install bolts that pass through the connector 42 and the base 41. The bolts can be used to stably connect the connector 42 and the base 41.

[0040] Both the connecting seat 43 and the limiting plate 7 are provided with several matching screw holes. The screw holes are used to install bolts that pass through the connecting seat 43 and the limiting plate 7. The connecting seat 43 and the limiting plate 7 are fastened by the bolts passing through the screw holes of the connecting seat 43 and the limiting plate 7.

[0041] The specific implementation method is as follows: When using, such as... Figure 1 The slope protection 6 shown is unfolded to facilitate personnel getting on and off the weighing platform 1. When it is necessary to retract the slope protection 6, it is rotated, and when rotated to a certain position, as shown... Figure 2 As shown, the limiting plate 7 contacts the side wall of the scale body 1 to restrict the rotation. At this time, under the action of the damper 4, the slope 6 will not fall quickly, preventing accidental injury to the user's hand. Then, force is applied to the slope 6, which will exceed the limiting capacity of the damper 4, causing the slope 6 to drive the rotation of the shaft 3 and then fall slowly to ensure stability.

[0042] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
