[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described in the following with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0039] The common desktop posture correctors on the market are mainly divided into two categories: fixed type and adjustable type. The posture corrector of the adjustable type can adjust the position of the limiting piece to a certain extent compared with the posture corrector of the fixed type. In order to adapt to the use requirements of multiple scenes, the limiting piece is placed in the use position in the learning scene, at this time, the limiting piece is usually vertical upward relative to the reference body, and in the use scene such as doing handwork, the limiting piece is placed in the storage position, but the existing limiting piece adjustable scheme is complex, and the adjustment range is limited, and the posture corrector cannot be hidden or stored in all directions, that is, the limiting piece cannot be completely stored below the reference body.

[0040] Based on this, the utility model provides a kind of turnover block assembly for eye protection table, it is provided with fitting portion on turnover piece, during turnover piece overturning process, fitting portion can cooperate with the edge of reference body, and provide avoidance space, to be able to completely store limiting piece below reference body.

[0041] Embodiment 1

[0042] According to the embodiments of the utility model, a kind of turnover block assembly for eye protection table is provided, combined Figures 1 to 6 As shown in the figure, including turnover piece 3. Turnover piece 3 is special-shaped piece, turnover piece 3 includes body 37, first installation part 38 and second installation part 39, one end of body 37 is provided with the first installation part 38 for being rotatably connected with reference body 4, the other end of body 37 is provided with the second installation part 39 for being connected with limiting piece 1, body 37 is provided with fitting portion 31 for being adapted with the edge of reference body 4.

[0043] It should be noted that fitting portion 31 is adapted with the edge of reference body 4, which means that fitting portion 31 on turnover piece 3 matches the edge of reference body 4 in shape and size, so as to ensure that turnover piece 3 can be overturned from second turnover position to first turnover position.

[0044] With the rotation of first installation part 38 relative to reference body 4 as reference, turnover piece 3 has at least first turnover position and second turnover position.

[0045] Combined Figure 3 And Figure 4As shown, when the turnover piece 3 is in the first turnover position, the fitting part 31 is matched with the edge of the reference body 4, and the second mounting part 39 is located at the side of the reference body, and the limiting piece 1 protrudes upward from the reference body 4, so that the limiting piece 1 can be stably supported on the table edge or other reference surface, which not only improves the overall stability of the eye protection table, but also prevents the limiting piece 1 from sliding or tilting during use, and ensures the correction effect.

[0046] In combination Figure 5 As shown, when the turnover piece 3 is in the second turnover position, the fitting part 31 is disengaged from the edge of the reference body 4, and the turnover piece 3 drives the limiting piece 1 to be accommodated below the reference body 4, so that the second mounting part 39 is located below the reference body 4, which simplifies the accommodation process of the limiting piece 1, and makes the limiting piece 1 completely hidden at the bottom of the reference body 4, solving the problem that the limiting piece 1 can only be partially hidden.

[0047] The above-mentioned turnover block assembly for the eye protection table, the design of the fitting part 31 enables the limiting piece 1 to cooperate with the edge of the reference body 4 during use, and the fitting part 31 provides a space for avoidance when the turnover piece 3 is turned over, so as to ensure that the turnover piece 3 can be turned over from the bottom of the reference body 4 to the side of the reference body 4, which not only reduces the complexity of the overall turnover piece 3, but also ensures smooth turnover of the turnover piece 3. By simply rotating the turnover piece 3, the user can quickly switch between use and storage without complex operation steps, which not only improves the user experience, but also makes the eye protection table more flexible and convenient to use in different scenarios.

[0048] When correcting the user's sitting posture, the turnover piece 3 can be turned to the first position to guide the user to recover to the correct sitting posture state through the limiting piece 1 protruding upward from the reference body 4, which not only helps to protect the user's eyesight, but also effectively prevents health problems such as cervical vertebra and lumbar vertebra caused by long-term improper sitting posture.

[0049] The above-mentioned turnover block assembly for the eye protection table does not need to be additionally damaged to the table or workbench, and is suitable for various tables or workbenches of different shapes and sizes, and has strong universality and adaptability. It can be conveniently used and stored in places such as home, office and school.

[0050] In some embodiments, the fitting part 31 includes a limiting groove formed with the edge of the reference body 4, and when the turnover piece 3 is in the first turnover position, the limiting groove is matched with the edge of the reference body 4, and the limiting groove can provide a space for avoidance during the turnover of the turnover piece 3, so as to ensure the normal turnover of the turnover piece 3. In this embodiment, the fitting part 31 is integrally formed with the body 37.

[0051] In some embodiments, the limiting groove is configured to accommodate the edge of the reference body 4 in a first direction perpendicular to the reference surface of the reference body when the turnover piece 3 is in the first turnover position. In this embodiment, the limiting groove can accommodate the edge of the reference body after the turnover piece 3 is turned to the first turnover position, thereby limiting the turnover piece 3 to a certain extent and keeping it in the first turnover position.

[0052] As an alternative embodiment, the limiting groove is only shaped to match the edge of the reference body, and the limiting groove does not accommodate the edge of the reference body.

[0053] In some embodiments, a flexible piece is provided on the fitting part, which has a shape-changing amount that matches the edge of the reference body 4. It should be noted that the flexible piece matches the edge of the reference body 4 in terms of shape and size. In this embodiment, the combination of the fixed fitting part 31 and the flexible piece ensures accurate alignment and positioning during each installation, improving the reliability and consistency of use. The self-adaptive capability of the flexible piece enables stable and reliable fixing effect even in complex environments. The material selection of the flexible piece can be optimized according to specific application scenarios, such as using soft and durable rubber or silicone materials, which can provide good friction and will not scratch the surface of the reference body 4, not only improving the user's comfort, but also protecting the surface of the reference body 4.

[0054] In some embodiments, the fitting part 31 is adjustable in a second direction, and the arrangement direction of the edge of the reference body 4 and the fitting part 31 matches the second direction. It should be noted that the arrangement direction of the edge of the reference body 4 and the fitting part 31 matches the second direction, which means that the direction has a certain angle with the edge of the reference body 4, which can be acute, right, or obtuse, and can be set based on specific application scenarios.

[0055] More specifically, the adjustable fitting part 31 in the second direction can include the following forms: the body 37 is provided with a first telescopic structure, and the body 37 is adjustable in length in the second direction; the fitting part 31 is provided with a second telescopic structure, and the fitting part 31 is adjustable in length in the second direction; the third telescopic structure is provided between the fitting part 31 and the body 37 to enable the fitting part 31 to move and adjust in the second direction. In this embodiment, by setting the fitting part 31 to be adjustable in the second direction, the fitting part 31 can adapt to the edges of various types of reference bodies. And by setting the fitting part 31 to be adjustable, when the turnover piece 3 switches from the first turnover position to the second turnover position, the fitting part 31 can be moved away from the edge of the reference body, so that the fitting part 31 is out of contact with the edge of the reference body, thereby facilitating the position switching of the turnover piece 3, avoiding collision between the turnover piece 3 and the edge of the reference body during turnover, and also avoiding the turnover piece 3 from being unable to turn to the position due to structural limitations.

[0056] The turnover member 3 is also rotatably arranged on the mounting member 2, which is arranged below the reference body 4, and the turnover member 3 is rotatably connected to the mounting member 2 through the first mounting portion 38.

[0057] As a specific embodiment, the mounting member 2 is a sliding structure, which can be adjusted in movement relative to the reference body 4. In this embodiment, the sliding structure can be used to control the distance between the fitting portion 31 and the edge of the reference body when the position of the turnover member 3 is switched, thereby facilitating the position switching of the turnover member 3.

[0058] In some embodiments, the fitting portion is provided with a positioning structure, which is adapted to enhance the connection between the fitting portion and the edge of the reference body 4 when the turnover member 3 is in the second turnover position. The positioning structure on the fitting portion 31 ensures that the limiting member 1 can be firmly fixed above the reference body 4 when in use, avoiding loosening or falling off due to accidental collision or external force.

[0059] In some embodiments, the positioning structure includes at least one friction component and / or an adsorption component. The friction component is a friction protrusion, which increases the friction between the fitting portion and the edge of the reference body 4. The adsorption component can be a suction cup or other structures with adsorption function.

[0060] In some embodiments, the side of the turnover member 3 opposite to the fitting portion 31 is provided with an inclined surface, which is used to reserve a storage space for the limiting member 1, avoiding interference between the turnover member 3 and the reference body 4. On the other hand, the material usage of the fitting portion 31 can be reduced, saving production cost.

[0061] In some embodiments, one end of the turnover member 3 is rotatably connected to the reference body 4 through a first rotating component, and the other end of the turnover member 3 is rotatably connected to the limiting member 1 through a second rotating component.

[0062] The first rotating component includes a first rotating shaft 32, and the turnover member 3 is rotatably arranged on the sliding structure through the first rotating shaft 32. The turnover member 3 is provided with a receiving groove, and the second rotating component includes a second rotating shaft 34, and the limiting member 1 is rotatably arranged in the receiving groove of the turnover member 3 through the second rotating shaft 34. The sliding structure is arranged at the outer two ends of the turnover member 3.

[0063] When the turnover member 3 is in the second turnover position, the first rotating shaft and the second rotating shaft are arranged obliquely upward, thereby enabling the side of the turnover member 3 away from the fitting portion to be provided with an inclined surface, reducing the possibility of interference between the turnover member 3 and the reference body 4.

[0064] In some embodiments, in combination with Figure 6As shown, the first rotating shaft 32 and the sliding structure, and the second rotating shaft 34 and the turnover piece 3 are respectively provided with fixing structures, which are suitable for positioning the turnover piece 3 and the limiting piece 1 after they are rotated to the positions. More specifically, the first rotating shaft 32 and the sliding structure are fixed by a fixing pin 36. The second rotating shaft 34 and the turnover piece 3 are fixed by a fixing block 35.

[0065] In some embodiments, the sliding structure is arranged on the bottom end surface of the reference body 4. When the sliding structure is arranged on the bottom end surface of the reference body 4, the height of the device as a whole can be reduced, and the device is more compact, which is convenient for storage and carrying. Since the sliding structure is located on the bottom end surface, it does not affect the overall aesthetics of the appearance of the device, and the product design is more simple and elegant.

[0066] The axis of the first rotating shaft 32 is located below the bottom end surface of the reference body 4, and thus when the turnover piece is rotated around the first rotating shaft 32, the turnover piece can be turned to the position directly below the reference body 4, so as to ensure the storage effect of the limiting piece 1.

[0067] When the turnover block assembly for the eye protection table is stored, the limiting piece 1 is arranged in parallel with the bottom end surface of the reference body 4. The use process of the turnover block assembly for the eye protection table is as follows:

[0068] When it is needed to use, the turnover piece 3 is turned by 180°, at this time, the fitting part of the turnover piece 3 is just clamped with the edge of the reference body 4, and then the limiting piece 1 is rotated by 90°, so that the side surface of the limiting piece 1 is parallel to the side surface of the reference body 4, and the limiting piece 1 protrudes upward from the top end surface of the reference body 4, and the user can use the limiting piece 1 to correct the sitting posture.

[0069] When it is needed to store, the limiting piece 1 is reversely rotated by 90° in the vertical plane, at this time, the limiting piece 1 is arranged in line with the turnover piece 3, and then the turnover piece 3 is reversely rotated by 180° (or less than or greater than 180°), so that the limiting piece 1 is stored at the bottom of the reference body 4, and the reference body 4 is hidden. When the bottom end surface of the reference body 4 is an inclined surface, the rotation angle of the turnover piece can be less than or greater than 180°, and the specific rotation angle is determined based on the arrangement form of the bottom end surface of the reference body 4.

[0070] Embodiment 2

[0071] The embodiment discloses a turnover block assembly for an eye protection table. Based on the embodiment 1, the difference between the embodiment and the embodiment 1 is that the fitting part is detachably arranged on the turnover piece 3. The fitting part can be conveniently detached and reinstalled, facilitating cleaning, maintenance and replacement. Users can adjust or replace the fitting part at any time according to needs, improving the flexibility and applicability of the device. The position of the fitting part arranged on the turnover piece 3 can be adjusted. Further, the position of the fitting part can be adjusted according to actual needs, so that the device can adapt to different use scenarios and requirements. For example, when using different sizes of workbenches or different heights of table edges, users can optimize the layout of the device by adjusting the position of the fitting part.

[0072] More specifically, the fitting part moves relative to the turnover piece 3. As an alternative embodiment, the turnover piece 3 is rotationally arranged on a sliding structure, and the sliding structure can move relative to the reference body 4.

[0073] Embodiment 3

[0074] The embodiment discloses a turnover block assembly for an eye protection table. Based on the embodiment 1 or the embodiment 2, the embodiment sets the turnover of the turnover piece 3 and the limiting piece 1 to an automatic turnover form. More specifically, a first micro motor can be arranged at the extension end of the first rotating shaft 32, and a second micro motor can be arranged at the extension end of the second rotating shaft 34. The driving of the first micro motor and the second micro motor replaces the manual turning of the turnover piece 3 and the limiting piece 1.

[0075] A sensor can also be integrated on the turnover piece 3 and the limiting piece 1. The sensor monitors the user's sitting posture and use time, providing real-time feedback and reminders to help users maintain correct posture. The sensor can be a posture sensor and / or a pressure sensor.

[0076] The posture sensor is installed at key positions of the turnover piece 3 and the limiting piece 1, such as the places in contact with the user's back or waist. The posture sensor is used to detect the acceleration change of the human body to determine whether the correct sitting posture is deviated. It can also detect the posture angle of the user's body.

[0077] The pressure sensor detects the pressure distribution of the user's back or waist. By analyzing the changes of the pressure points, it can be determined whether the user has maintained the same posture for a long time or whether there is uneven pressure distribution, prompting the user to adjust the posture.

[0078] In combination with the intelligent control system, the detection information of the sensor is fed back to the intelligent control system. The intelligent control system controls the second micro motor based on the human sitting posture, so that the second micro motor drives the second rotating shaft 34 and the limiting piece 1 to automatically turn over and adjust, simplifying the user's operation steps and improving the user experience.
