Description

Technical Field

[0001] This utility model relates to the field of ergonomic office equipment technology, specifically to a lifting panel for correcting sitting posture. Background Technology

[0002] In office and study settings, prolonged sitting and improper posture often lead to health problems such as lower back pain and spinal deformities. Therefore, correcting posture has become an important part of daily life. Among these, adjustable chair panels are commonly used tools to assist in correcting posture. By adjusting their height, they can adapt to the body proportions of different users (such as height and desk / chair height), helping users maintain a straight back and level gaze. They are widely used in homes, offices, schools, and other places.

[0003] Currently, there are technical problems with the height adjustment of posture correction panels on the market: most products adopt a "manual step-by-step adjustment" structure. For example, you need to use tools such as screwdrivers and wrenches to loosen the fixing screws at the bottom of the panel, then manually lift the panel to the estimated height, and then tighten the screws again after adjustment.

[0004] The above adjustment methods are not only cumbersome but also time-consuming. On the one hand, users need to repeatedly try and fail (e.g., it is difficult to align the panel to the correct height on the first try, requiring multiple loosening and tightening of screws). On the other hand, users need to frequently get up and bend over during the adjustment process, making it impossible to complete the adjustment quickly while maintaining a seated posture. This deficiency leads users to abandon adjustments when they need to temporarily adjust the height (e.g., when changing users or adjusting the table and chair combination) due to the "troublesome operation and long time consumption," ultimately preventing the height adjustment panel from fully correcting posture and even exacerbating posture problems due to unsuitable height.

[0005] In summary, existing posture correction lifting panels suffer from technical problems such as "cumbersome adjustment steps and long adjustment time," making it difficult to meet users' needs for "convenient and efficient adjustment." There is an urgent need for a lifting panel structure that can simplify the adjustment steps and shorten the adjustment time to improve the practicality and corrective effect of the product. Utility Model Content

[0006] To overcome the above-mentioned defects, an embodiment of the present invention provides a lifting panel for correcting sitting posture, which is used to correct the user's sitting posture, including: a panel, wherein a through groove is provided on the side of the panel away from the user; A support cylinder is provided through the through groove, and several grooves are provided on the side wall of the support cylinder along the height direction. The support cylinder is used to support the panel. Linkage mechanism, connecting the panel; The linkage mechanism includes a first locking member, which can be engaged into the groove of the support cylinder to press against the side wall of the support cylinder; the first locking member can be engaged into different grooves to adjust the tilt angle of the panel.

[0007] Preferably, the two side walls facing away from each other of the support cylinder are provided with a plurality of the grooves, and the linkage mechanism further includes a second clamping member; The first clamping member can be engaged in the groove on one side wall of the support cylinder, and the second clamping member can be engaged in the groove on the other side wall of the support cylinder, so as to cooperate with the first clamping member to fix the support cylinder.

[0008] Preferably, the second clamping member is connected to the first clamping member; operating the first clamping member can cause the second clamping member to engage or disengage from the groove in a coordinated manner.

[0009] Preferably, the first clamping member has a slot, which is used for the second clamping member to extend into the first clamping member.

[0010] Preferably, the first clamping member has a plurality of first sliding grooves; The linkage mechanism also includes: The first sliding column has several of them, and each first sliding column corresponds to a first sliding groove. The first sliding column is fixedly installed on the panel and can slide in the first sliding groove so that the first clamping member is close to or away from the side wall of the support cylinder.

[0011] Preferably, the second clamping member has a second sliding groove; The linkage mechanism also includes: The second sliding post is disposed on the panel and abuts against the second sliding groove. The second sliding post can slide in the second sliding groove so that the second clamping member is close to or away from the side wall of the support cylinder.

[0012] Preferably, a plurality of grooves are arranged at intervals on the same side wall of the support cylinder, and the grooves at the same height on the opposite side walls correspond one-to-one. The first clamping member and the second clamping member can be engaged into two grooves at the same height to adjust the support height of the support cylinder on the panel.

[0013] Preferably, the first clamping member also has a linkage block; The linkage mechanism also includes: A button is slidably mounted on the outer wall of the first clamping member, and the linkage block is connected to the button. A reset spring is sleeved on the linkage block. When the button is pressed down, the linkage block can compress the reset spring so that the first locking member and the second locking member slide in opposite directions within the first sliding groove and the second sliding groove.

[0014] Preferably, the support cylinder has a storage cavity, the opening of which faces upward toward the panel; The surface of the support cylinder located below the panel is an inclined surface.

[0015] Preferred options also include: A positioning seat is provided on the side wall of the panel, and the positioning seat can contact the user's chest to adjust the user's sitting posture.

[0016] The beneficial effects of this utility model are as follows: In this invention, when the height of the lifting panel needs to be adjusted, the first clamping member disengages from the groove. After the support cylinder is moved to the desired height, the first clamping member engages with the grooves on both sides of the support cylinder. The combined pressure of these two components restricts the relative position of the support cylinder and the panel, thus fixing the panel height. The inclined surface below the support cylinder can be adapted to a surface, such as a tabletop, enhancing support stability. By adjusting the position of the first clamping member in different grooves, the angle between the panel and the tabletop can be increased or decreased. The structure of the first clamping member engaging with the grooves on both sides of the support cylinder allows for fixing or separating the support cylinder and the panel without the need for tools. The structure of the support cylinder penetrating the panel through a groove allows the panel to move directly relative to the support cylinder during height adjustment, eliminating the need for the user to lift the panel and reducing repeated trial and error. This simplifies the panel adjustment process, shortens the adjustment time, and solves the problems of cumbersome and time-consuming adjustments. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0021] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-6 As shown, it illustrates a posture-correcting lifting panel in one embodiment of the present invention, including a panel 1, a support cylinder 2, and a linkage mechanism 3. The linkage mechanism 3 includes a first clamping member 31, which can be engaged in the groove 201 of the support cylinder 2 to press against the side wall of the support cylinder 2. The first clamping member 31 can be engaged in different grooves 201 to adjust the tilt angle of the panel 1.

[0027] The linkage mechanism 3 also includes a second clamping member 32; a through groove 101 is provided at the corner of the panel 1 away from the user; there are several support cylinders 2, each corresponding to a through groove 101, and the support cylinder 2 is disposed through the through groove 101. The surface of the support cylinder 2 located below the panel 1 is an inclined surface 21. Several grooves 201 are provided on the two side walls of the support cylinder 2, and the support cylinder 2 is used to support the panel 1; a first clamping member 31 is disposed on the panel 1, and the first clamping member 31 can be inserted into the groove 201 on one side wall of the support cylinder 2 to press against the side wall of the support cylinder 2; a second clamping member 32 is disposed on the panel 1, and the second clamping member 32 can be inserted into the groove 201 on the other side wall of the support cylinder 2 to cooperate with the first clamping member 31 to fix the support cylinder 2.

[0028] Specifically, when the height of panel 1 needs to be adjusted, the first clamping member 31 and the second clamping member 32 are disengaged from the groove 201. After moving the support cylinder 2 to the required height, the first clamping member 31 and the second clamping member 32 are simultaneously engaged into the corresponding grooves 201 on the side walls to fix panel 1. By engaging the first clamping member 31 and the second clamping member 32 into the grooves 201 on both side walls of the support cylinder 2, the opposing force of the two members restricts the relative position of the support cylinder 2 and panel 1, thus fixing the height of panel 1. The inclined surface 21 below the support cylinder 2 can be adapted to the placement surface, such as a tabletop, to enhance the stability of the support.

[0029] It should be noted that by adjusting the first clamping member 31 and the second clamping member 32 to be located in different grooves 201, the angle between the panel 1 and the tabletop can be increased or decreased. The second clamping member is connected to the first clamping member; operating the first clamping member can cause the second clamping member to engage or disengage from the groove in a coordinated manner.

[0030] Furthermore, by using the first clamping member 31 and the second clamping member 32 to engage with the grooves 201 on both sides of the support cylinder 2, the support cylinder 2 can be fixed or separated from the panel 1 without the need for tools. The support cylinder 2 penetrates the through groove 101 of the panel 1, allowing the panel 1 to move directly relative to the support cylinder 2 during height adjustment. Users can adjust the height without lifting the panel 1, reducing repeated trial and error. This simplifies the steps for adjusting the panel 1, shortens the adjustment time, and solves the problems of cumbersome and time-consuming adjustments.

[0031] For example, such as Figure 1 As shown, in some examples, a slot is provided on the upper side wall of the first clamping member 31, and the slot is used for the second clamping member 32 to extend into the first clamping member 31.

[0032] Specifically, the second clamping member 32 can be connected to the first clamping member 31 through the slot. When the first clamping member 31 and the second clamping member 32 cooperate to fix the support cylinder 2, part of the structure of the second clamping member 32 extends into the first clamping member 31 through the slot, and the two form a compact structure near the support cylinder 2.

[0033] It should be noted that the second clamping member 32 has a portion of its structure inserted into the first clamping member 31 through a slot, enabling one-click unlocking and simplifying the unlocking steps between the support cylinder 2 and the first and second clamping members 31 and 32. Simultaneously, the slot allows the second clamping member 32 to extend into the first clamping member 31, reducing the overall area occupied by the two clamping members on the panel 1 and making the structure more compact. Furthermore, the partial overlap of the two structures enhances the stability of the fit, preventing interfering with each other during adjustment or use and thus improving the smoothness of the adjustment operation.

[0034] For example, such as Figure 4 and Figure 5 As shown, in some examples, the first clamping member 31 is provided with a plurality of first sliding grooves 3101; a plurality of first sliding posts 33 are also fixedly provided on the panel 1, the first sliding posts 33 correspond one-to-one with the first sliding grooves 3101, the first sliding posts 33 can slide in the first sliding grooves 3101, so that the first clamping member 31 is close to or away from the side wall of the support cylinder 2.

[0035] Specifically, during adjustment, pushing the first locking member 31 causes the first sliding column 33 to slide along the first sliding groove 3101, thereby disengaging or engaging the first locking member 31 into the groove 201 on the side wall of the support cylinder 2. The mating structure between the first sliding column 33 and the first sliding groove 3101 limits the direction of movement of the first locking member 31, preventing it from shifting or wobbling during adjustment, and ensuring that the first locking member 31 can accurately engage in the groove 201. At the same time, the sliding engagement reduces the resistance when the first locking member 31 moves, making the adjustment operation more effortless and further shortening the adjustment time.

[0036] For example, such as Figure 4 and Figure 5 As shown, in some examples, the second clamping member 32 has a second sliding groove 3201, and the panel 1 is also provided with a second sliding post 34. The second sliding post 34 abuts against the second sliding groove 3201 and can slide in the second sliding groove 3201 so that the second clamping member 32 is close to or away from the side wall of the support cylinder 2.

[0037] Specifically, during adjustment, the second sliding column 34 slides along the second sliding groove 3201, causing the second clamping member 32 to move synchronously, disengaging from or engaging with the groove 201 on the other side wall of the support cylinder 2. It should be noted that the first clamping member 31 and the second clamping member 32 can slide simultaneously towards or away from each other in the first sliding groove 3101 and the second sliding groove 3201, so as to simultaneously clamp or release the support cylinder 2.

[0038] Furthermore, the cooperation between the second sliding column 34 and the second sliding groove 3201 provides a stable moving trajectory for the second clamping member 32, enabling it to coordinate with the movement of the first clamping member 31 and ensuring that both can be accurately engaged in the corresponding groove 201 at the same time. The sliding structure reduces the moving resistance of the second clamping member 32 and works together with the sliding structure of the first clamping member 31 to make the overall adjustment operation smoother and more efficient.

[0039] For example, such as Figure 3 As shown, in some examples, several grooves 201 are arranged at intervals on the same side wall of the support cylinder 2, and the grooves 201 at the same height on the opposite side walls correspond one-to-one. The first clamping member 31 and the second clamping member 32 can be clamped into the two grooves 201 at the same height to adjust the support height of the support cylinder 2 on the panel 1.

[0040] Specifically, when adjusting the height, the first clamping member 31 and the second clamping member 32 are simultaneously engaged into the grooves 201 on both sides corresponding to the target height, thus fixing the panel 1 at the required height. It should be noted that the grooves 201 are provided with different lengths. For example, the support cylinder 2 has two grooves 201 on both sides, and the lengths of these two grooves 201 differ significantly. This design is to make it convenient for the user to adjust the panel 1 without having to look at the bottom.

[0041] Furthermore, the corresponding arrangement of the grooves 201 at the same height ensures the consistency of the height when the first clamping member 31 and the second clamping member 32 are engaged, preventing the panel 1 from tilting due to the different engagement heights on both sides; the spaced grooves 201 provide multiple adjustment positions of different lengths, allowing users to directly select the target position, reducing the process of repeated trial and error, further shortening the adjustment time, and improving the accuracy of height adjustment.

[0042] For example, such as Figure 5 As shown, in some examples, the first clamping member 31 also has a linkage block 311; the panel 1 also includes a button 35 and a return spring 36. The button 35 is slidably disposed on the outer wall of the first clamping member 31, and the linkage block 311 is fixedly connected to the button 35; the return spring 36 is sleeved on the linkage block 311. After the button 35 is pressed down, the linkage block 311 squeezes the return spring 36 to compress it, so that the first clamping member 31 and the second clamping member 32 slide in opposite directions in the first slide groove 3101 and the second slide groove 3201.

[0043] Specifically, when the height needs to be adjusted, press down button 35. The first clamping member 31 and the second clamping member 32 slide away from the groove 201. After moving the support cylinder 2 to the target height, release button 35. The reset spring 36 drives the two to slide towards each other and lock into the corresponding groove 201.

[0044] Furthermore, the linkage structure between button 35 and linkage block 311 allows the user to control the two locking parts to simultaneously disengage or engage with the groove 201 with a single operation, eliminating the need to operate the two locking parts separately and simplifying the adjustment steps. The reset spring 36 ensures that the locking parts can automatically reset and engage after button 35 is released, avoiding the tediousness of manual reset, further shortening the adjustment time and improving the ease of operation.

[0045] For example, such as Figure 6As shown, in some examples, the support cylinder 2 has a storage cavity 202, the opening of which faces upwards towards the panel 1. Specifically, users can place small items such as pens and sticky notes into the storage cavity 202 and retrieve them directly from the opening when needed. The storage cavity 202 allows the support cylinder 2 to perform its support function while also adding storage functionality, eliminating the need for additional storage components and saving overall space. The structure with the opening facing upwards towards the panel 1 makes it convenient for users to retrieve and place items while seated, adapting to the usage scenarios of the lifting panel 1 and enhancing the product's practicality.

[0046] For example, such as Figure 4 and Figure 5 As shown, in some examples, fastening screws are detachably provided on the first sliding post 33 and the second sliding post 34, which are used to fasten the first clamping member 31 and / or the second clamping member 32 to the panel 1.

[0047] It should be noted that both the inner walls of the first sliding post 33 and the second sliding post 34 have threaded sections. The fastening screw is threadedly connected to the first sliding post 33 and the second sliding post 34. The diameter of the nut of the fastening screw is larger than the diameter of the first sliding groove 3101 and the second sliding groove 3201. The first locking member 31 and the second locking member 32 are first placed on the corresponding first sliding post 33 and the second sliding post 34, and then the fastening screw is installed on the first sliding post 33 and the second sliding post 34, so that the nut of the fastening screw is placed above the first sliding groove 3101 and the second sliding groove 3201, which does not affect the sliding unlocking of the first locking member 31 and the second locking member 32.

[0048] Meanwhile, the fastening screws can fix the clamping parts after adjustment, preventing the clamping parts from sliding or falling out of the groove 201 due to vibration or collision during use, thus enhancing the stability of the structure; the detachable structure does not affect the realization of the adjustment function, taking into account both the reliability of fixation and the flexibility of adjustment.

[0049] For example, such as Figure 6 As shown, in some examples, a limit seat 4 is also provided on the panel 1. The limit seat 4 can contact the user's chest to adjust the user's sitting posture. Specifically, when the user sits in front of the panel 1, the chest contacts the limit seat 4, and when the body leans forward, it is blocked by the limit seat 4, thereby adjusting to the correct sitting posture.

[0050] The combination of the limit seat 4 and the panel 1 enables the lifting panel 1 to achieve both height adjustment and posture restraint functions. By contacting the chest to restrict forward leaning, it works in conjunction with height adjustment to assist in correcting posture from two dimensions, thereby improving the product's corrective effect and solving the problem of existing products that can only adjust height but lack posture restraint.

[0051] It should be noted that the limiting seat 4 can slide and rise to adjust its height, making it suitable for users of different heights and increasing the applicability of the device.

[0052] For example, such as Figure 6 As shown, in some examples, a rubber pad 41 is provided on the limiting seat 4, and the limiting seat 4 contacts the user's body through the rubber pad 41.

[0053] It should be explained that the rubber pad 41 makes the contact between the limit seat 4 and the user's body softer, avoiding the pressure or discomfort that may be caused by hard contact; at the same time, the rubber pad 41 can increase the friction during contact, reduce the relative sliding between the body and the limit seat 4, ensure the stable operation of the limiting function, and improve the comfort of use without affecting the posture correction effect.

[0054] 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.
