[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below. 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-correcting table in the market is mainly divided into two types: fixed type and adjustable type. The adjustable posture-correcting table can adjust the position to a certain extent, and the adjustment range is still limited, and only 180° rotation can be performed, that is, the posture-correcting table is rotated from the vertical upward mode to the vertical downward mode. Although this adjustment mode can realize the hiding of the posture-correcting table to a certain extent, this adjustment mode cannot realize all-around hiding or storage.

[0040] Based on this, the utility model provides a hidden eye-protecting posture-correcting table, adopts two-stage overturning mode, makes the limiting piece can realize at least 270° rotation, thereby completely hides in the table bottom, solves the problem that the present limiting piece can only be partially hidden.

[0041] The first aspect of the hidden eye-protecting posture-correcting table of the utility model and the second aspect of the study table of the utility model will be described in detail below in combination with Figures 1 to 7 .

[0042] Embodiment 1

[0043] According to the embodiments of the utility model, the first aspect provides a hidden eye-protecting posture-correcting table, in combination with Figures 1 to 5 , which comprises a base block 2 and a limiting piece 1. The base block 2 is rotationally arranged on the installation reference 3. The limiting piece 1 is rotationally arranged on the base block 2.

[0044] The limiting piece 1 has a first position and a second position. In combination with Figure 1 , when the limiting piece 1 is in the first position, the limiting piece 1 is stored below the installation reference 3, and at this time, it is the hidden state of the limiting piece 1; in combination with Figure 2 , when the limiting piece 1 is in the second position, the limiting piece 1 protrudes upwards from the side of the installation reference 3 and protrudes upwards from the installation reference 3, and at this time, it is the use state of the limiting piece 1, so as to be suitable for sitting posture correction. When the limiting piece 1 switches between the first position and the second position, the base block 2 and the limiting piece 1 rotate around the first plane and the second plane respectively, and the first plane and the second plane are intersecting planes.

[0045] The above-mentioned hidden eye protection posture table adopts a two-stage overturning mode, so that the limiting piece 1 can rotate by at least 270°, thereby being completely hidden under the table, solving the problem that the existing limiting piece 1 can only be partially hidden. Users can easily switch the limiting piece 1 from the hidden state to the use state as needed, which is simple to operate and does not require disassembly, thereby improving the convenience and flexibility of use. When the limiting piece 1 is in the use state, its stable support can effectively prevent safety hazards caused by improper sitting posture. At the same time, when the limiting piece 1 is in the hidden state, it is completely stored under the installation reference 3 and does not hinder the user or surrounding objects.

[0046] The above-mentioned hidden eye protection posture table is suitable for office environments or home environments with high space requirements, such as small-sized homes, shared office spaces, etc., and can provide effective sitting posture correction functions in limited space.

[0047] The current posture table rotates to a vertical downward position, which occupies the vertical space under the desktop and easily affects users sitting on the side of the desktop. In order to solve this problem, in some embodiments, the base block 2 is rotationally arranged on the bottom end face of the installation reference 3. When the limiting piece 1 is converted from the first position (hidden state) to the second position (use state), the base block 2 rotates around the first plane, so that the limiting piece 1 extends from the side of the installation reference 3, and the limiting piece 1 rotates around the second plane to a position protruding from the top end face of the installation reference 3. Conversely, when the limiting piece 1 is converted from the second position to the first position, the limiting piece 1 rotates around the second plane to below the installation reference 3, and the base block 2 rotates the limiting piece 1 around the first plane to make the limiting piece 1 parallel to the bottom end face of the installation reference 3, thereby making the limiting piece 1 stored below the installation reference 3. In this embodiment, the limiting piece 1 is overturned to be parallel to the bottom end face of the installation reference 3, thereby avoiding the problem that the limiting piece 1 occupies a large vertical space under the desktop.

[0048] In some embodiments, the base block 2 includes a body part 21 and an extension part 22. The top end of the body part 21 is provided with a rotating part 23, which ensures that the base block 2 can rotate smoothly on the bottom end face of the installation reference 3, avoiding the problem of jamming or damage due to uneven rotation. The extension part 22 is arranged on the side of the body part 21, and the limiting piece 1 is rotationally arranged on the extension part 22. In this embodiment, as shown in Figure 5 As shown, the bottom end face of the installation reference 3 is provided with a positioning hole 31, and the rotating part 23 is rotationally arranged in the positioning hole 31.

[0049] When the limiting piece 1 is in the first position, the normal projection of the installation reference 3 is taken as the reference, the normal projection of the base block 2 and the limiting piece 1 all fall within the range of the normal projection of the installation reference 3, and the extension 22 is hidden below the installation reference 3, not only achieving the effect of complete invisibility, but also avoiding obstacles to the user or surrounding objects, improving safety. When the limiting piece 1 is in the second position, at least part of it protrudes from the side of the installation reference 3, facilitating the flipping of the limiting piece 1.

[0050] In this embodiment, due to the design of the base block 2 and the extension 22, the user can easily switch the limiting piece 1 from the hidden state to the use state, and vice versa. This convenient operation mode significantly improves the user's experience. The side of the extension 22 provides more installation and adjustment space for the limiting piece 1, which can be personalized according to different table types and use requirements, enhancing the universality and adaptability of the product.

[0051] Even if the installation reference 3 is inclined, this design can still ensure that the limiting piece 1 is in a state parallel to the side of the installation reference 3 after flipping, ensuring that the correction effect is not affected.

[0052] More specifically, the length of the extension 22 protruding from the side of the installation reference 3 is not less than the thickness of the limiting piece 1, and then when the extension 22 protrudes from the side of the installation reference 3, the limiting piece 1 can be flipped to a position parallel to the side of the installation reference 3, thereby ensuring the normal use of the limiting piece 1.

[0053] The axis of rotation of the limiting piece 1 relative to the base block 2 is located below the installation reference 3. When the limiting piece 1 is in the first position, the limiting piece 1 and the base block 2 are both arranged horizontally, and the distance between the top end face of the base block 2 and the bottom end face of the installation reference 3 is not greater than the distance between the top end face of the limiting piece 1 and the bottom end face of the installation reference 3, and then when the limiting piece 1 is flipped to a position flush with the base block 2, and the base block 2 is horizontally rotated, the limiting piece 1 can be rotated to be directly below the installation reference 3, thereby realizing the storage and hiding of the limiting piece 1.

[0054] When the above-mentioned hidden eye protection posture table is stored, the limiting piece 1 is arranged parallel to the bottom end face of the installation reference 3, and the first use process of the above-mentioned hidden eye protection posture table is as follows:

[0055] When it is needed to use, the base block 2 connected with the limiting piece 1 in the hidden state is horizontally rotated by 180°, at this time, the extension 22 of the base block 2 and the limiting piece 1 extend outward from the side of the installation reference 3, that is, at this time, the limiting piece 1 is in a temporary hidden position, then the limiting piece 1 is rotated by 90° in the vertical plane, that is, the side of the limiting piece 1 is parallel to the side of the installation reference 3, the limiting piece 1 protrudes upward from the top end surface of the installation reference 3, so that the limiting piece 1 is converted to the use state, and the user can use the limiting piece 1 to correct the sitting posture.

[0056] When it is needed to store, the limiting piece 1 in the use state is reversely rotated by 90° in the vertical plane, at this time, the limiting piece 1 is arranged in line with the base block 2, at this time, the limiting piece 1 is in a temporary hidden position, then the base block 2 is reversely horizontally rotated by 180° (or less than or greater than 180°), so that the limiting piece 1 is stored in the bottom of the installation reference 3, at this time, the limiting piece 1 is converted to the hidden state, and the hiding of the limiting piece 1 is realized.

[0057] When the above-mentioned hidden eye-protecting correct posture table is stored, the limiting piece 1 is arranged perpendicularly to the bottom end surface of the installation reference 3, and the second use process of the above-mentioned hidden eye-protecting correct posture table is as follows:

[0058] When it is needed to use, the base block 2 is horizontally rotated by 90°, at this time, the extension 22 of the base block 2 and the limiting piece 1 extend outward from the side of the installation reference 3, then the limiting piece 1 is rotated by 90° in the vertical plane, that is, the side of the limiting piece 1 is parallel to the side of the installation reference 3, the limiting piece 1 protrudes upward from the top end surface of the installation reference 3, so that the user can use the limiting piece 1 to correct the sitting posture.

[0059] 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 base block 2, then the base block 2 is reversely horizontally rotated by 180° (or less than or greater than 180°), so that the limiting piece 1 is stored in the bottom of the installation reference 3, and the hiding of the limiting piece 1 is realized.

[0060] Embodiment 2

[0061] The embodiment discloses a hidden eye-protecting correct posture table, and the difference between the embodiment and the embodiment 1 is that the embodiment introduces a sliding assembly, and the storage and expansion mechanism of the limiting piece 1 is further optimized.

[0062] More specifically, the base block 2 is rotationally arranged on the sliding assembly, the sliding assembly is slidably matched with the installation reference 3, and the base block 2 is slidably arranged along the width direction or the height direction of the installation reference 3 through the sliding assembly.

[0063] When the limiting piece 1 is converted from the first position to the second position, the sliding assembly drives the base block 2 and the limiting piece 1 to extend from the side of the installation reference 3 along the first direction, and then when the limiting piece 1 is flipped, no interference is generated between the limiting piece 1 and the installation reference 3, so that the smooth flipping of the limiting piece 1 is ensured.

[0064] When the limiting piece 1 is converted from the second position to the first position, after the limiting piece 1 rotates around the second plane to below the installation reference 3, the sliding assembly drives the base block 2 and the limiting piece 1 to slide below the installation reference 3 along the second direction. The first direction is opposite to the second direction.

[0065] Due to the existence of the sliding assembly, the device can better adapt to the changes of different desktop heights and shapes, and is suitable for more complex work and life scenes.

[0066] As a specific embodiment, the sliding assembly includes a sliding rail, and the base block 2 is provided with a sliding part matched with the sliding rail.

[0067] As a further improved embodiment, the sliding rail is linear, curved or zigzag, and the specific shape and specification of the sliding rail can be arranged according to the actual shape and specification of the installation reference 3, so that the limiting piece 1 is hidden in the specified position at the bottom end face of the installation reference 3 after moving along the sliding rail. For example, after the limiting piece 1 is flipped twice, the limiting piece 1 slides along the obliquely arranged sliding rail to the corner position of the installation reference 3, so that the whole standing posture table is far away from the normal sitting position of the human body, and the situation that the whole standing posture table touches the human body after being stored can be effectively avoided.

[0068] As a further improved embodiment, the base block 2 is driven to move along the sliding rail under the electric driving structure or the manual adjusting handle, so that the sliding of the base block 2 and the limiting piece 1 is more convenient. For example, when the sliding rail is a linear sliding rail, a lead screw can be arranged in the sliding rail, a lead nut is arranged on the sliding part, the lead screw is matched with the lead nut, and a motor is arranged at the end of the lead screw. When the motor operates, the motor can drive the lead screw to rotate, and then drive the lead nut, the base block 2 and the limiting piece 1 to move to the specified position. This kind of mode can be applied to the situation that the position where the standing posture table is to be stored is far away from the side of the installation reference 3 and is not convenient for manual operation. In addition, a manual adjusting handle can also be used to directly push the base block 2 and the limiting piece 1 to slide along the sliding rail.

[0069] Embodiment 3

On the basis of the embodiment 1, the difference between the embodiment and the embodiment 1 is that the base block 2 is arranged in a telescopic form, and the base block 2 is arranged to be telescopic along the width direction or the height direction of the installation reference 3.

[0071] When the limiting piece 1 is converted from the first position to the second position, the base block 2 is elongated to drive the limiting piece 1 to extend from the side of the installation reference 3, and then when the limiting piece 1 is flipped, the limiting piece 1 will not touch the installation reference 3, thereby reducing the interference of the limiting piece 1 with the installation reference 3 during the flipping. When the limiting piece 1 is converted from the second position to the first position, after the limiting piece 1 is rotated around the second plane to below the installation reference 3, the base block 2 is contracted to allow the limiting piece 1 to be accommodated below the installation reference 3.

[0072] More specifically, the body part 21 and the extension part 22 of the base block 2 are separately arranged, and a telescopic rod is arranged between the body part 21 and the extension part 22. When the extension part 22 is pulled, the extension part can be moved along the direction of the telescopic rod. The direction of the telescopic rod is perpendicular to the side of the installation reference 3, or the direction of the telescopic rod has a certain angle with the side of the installation reference 3, and then when the telescopic rod is elongated, the limiting piece 1 can extend from the side of the installation reference 3, thereby avoiding the interference of the limiting piece 1 with the side of the installation reference 3 during the rotation.

[0078] The first limiting structure and the second limiting structure are both magnetic attraction structures, and the magnetic attraction structure comprises a first magnet arranged on the limiting piece 1 and a second magnet arranged at a corresponding position of the installation reference 3. When the first magnet on the limiting piece 1 coincides with the second magnet on the base block 2, the first magnet and the second magnet are adsorbed and fixed.
