Description

Technical Field

[0001] This utility model relates to the field of desk technology, and in particular to a detachable posture correction device for a desk and a desk. Background Technology

[0002] Existing desks have significant shortcomings in achieving the ergonomically designed "one-fist distance" (approximately 10cm from the chest to the edge of the desk). When using a desk, users often unconsciously press their bodies against the edge, making it impossible to maintain a proper sitting posture. Maintaining this incorrect posture for a long time can easily lead to health problems such as spinal deformities and vision loss. This is especially true for adults with disabilities and children with poor self-discipline, where maintaining correct posture is even more difficult, posing particularly significant health risks.

[0003] Currently, most desks on the market use fixed or rotatable supports to help correct posture. However, in actual use, when not in use, the rotatable supports need to be rotated downwards for storage. This operation causes interference between the supports and the desk's built-in drawers, preventing the drawers from opening properly. To open the drawers, users must first rotate the supports upwards, which is cumbersome and extremely inconvenient.

[0004] Furthermore, the existing support structure of desks still occupies a certain amount of desktop space, reducing the effective utilization rate of the desktop and failing to maximize its utilization. When the desk needs to be used for other functions, such as painting or handicrafts, which require a larger surface area, the presence of the support structure can hinder the user's operation and affect the multi-functional use of the desk. Summary of the Invention

[0005] This utility model aims to address the shortcomings of existing technologies by providing a detachable posture correction device and desk for use on a desk, which solves the user's posture problem without affecting the use of drawers and desktop space.

[0006] To solve the above-mentioned technical problems, this utility model provides a detachable posture correction device for a desk, including a support device and a base. The base is detachably installed on the bottom of the desk tabletop, and the base is close to the front side of the tabletop, which is the side of the tabletop facing the user. The support device is detachably connected to the base and stands on the front side of the tabletop.

[0007] The support device includes a rotating support, a telescopic support, and a plate structure. The rotating support and the plate structure are respectively installed at both ends of the telescopic support, and the plate structure and the rotating support face opposite directions.

[0008] The base includes a groove structure. When the base is installed on the bottom of the desktop, the groove structure cooperates with the bottom surface of the desk to form a slot structure. The insert plate structure is inserted into the slot structure to form a detachable connection.

[0009] Furthermore, the base is made of a magnetically conductive metal material, and the base includes mounting portions disposed on both sides of the groove-shaped structure; the mounting portions include mounting holes, and the base is mounted to the bottom of the desktop through the mounting holes and screws.

[0010] Furthermore, the telescopic support includes a lower tube seat, an upper tube seat sleeved within the lower tube seat, and a locking structure. The upper tube seat can slide up and down along the height direction of the lower tube seat. The locking structure is used to lock the sliding of the upper tube seat. The locking structure can be operated to release the locking of the upper tube seat.

[0011] Furthermore, the locking structure includes a serrated structure disposed on one side wall of the upper tube seat and a snap-on button disposed on the corresponding side wall of the lower tube seat. The snap-on button includes snap teeth, which engage with the serrated structure to form a locking engagement.

[0012] Furthermore, the lower tube seat is provided with a mounting groove structure on the corresponding side wall, and a slot is opened at the location of the mounting groove structure; the snap button is rotatably installed in the mounting groove structure via a connecting rod, and the connecting rod is located in the middle of the snap button;

[0013] One end of the snap button is provided with the snap tooth, and the other end is provided with an elastic element. The elastic element is pressed between the snap button and the mounting groove structure, and the snap tooth of the snap button corresponds to the position of the groove.

[0014] When the other end of the latch button is lifted by the elastic element, the latch button rotates around the connecting rod so that the latch teeth engage with the serrated structure; the other end of the latch button can be pressed to squeeze the elastic element so that the latch teeth disengage from the serrated structure.

[0015] Furthermore, the tooth includes two contact endpoints, and the tooth pitch of the serrated structure is 2.5 times the width of the contact endpoints.

[0016] Furthermore, the insert plate structure is made of metal material, and the four edges of the insert plate structure are rounded; the insert plate structure is installed at the bottom of the lower tube seat by a screw connection structure.

[0017] Furthermore, the rotating support includes a chest support contact pad, two rotating seats, and a screw structure, wherein the screw structure includes a nut;

[0018] The two rotating seats are fixed at intervals on the back of the breast support contact pad. The upper tube seat includes a bracket, which is inserted between the intervals of the two rotating seats and is rotatably connected to the breast support contact pad through the screw structure. The rotation angle of the breast support contact pad relative to the bracket is in the range of 0°-65°.

[0019] This utility model also provides a desk, which includes a desktop, drawers, and a detachable posture correction device for the desk.

[0020] There is a gap between the drawer front and the bottom of the desktop, and the drawer front is used to be operated to pull open or push back the drawer; the base is detachably installed on the bottom of the desk desktop, and the base is located within the gap between the drawer front and the bottom of the desktop.

[0021] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0022] 1. This utility model provides an external posture correction device that can be installed on a desk using an external mounting method, and is compatible with most ordinary desks on the market. The posture correction device uses a base to install itself on the bottom of the desk surface, forming a slot structure. Combined with the insert structure of the support device, a slot-type connection structure is formed, allowing for quick assembly and disassembly. When using the support device for writing and reading, it helps maintain a scientifically correct posture with a distance of "one fist" (chest to edge of the desk) between the user and the desk edge. When using the desk for other functions (drawing, crafts, etc.), the support device can be quickly pulled out and removed without affecting the use of the desk or drawers underneath, making it more convenient.

[0023] 2. The modular combination of the posture correction device and the desk is achieved through the detachable plug-in structure of the base and support device. When in use, it can force users to maintain a scientific sitting posture of "one fist distance" to prevent the user from leaning forward and getting too close to the desktop, which can easily lead to health problems such as myopia and spinal curvature. It can also be quickly disassembled when not in use, without taking up desktop space or interfering with the opening and closing of drawers, thus taking into account both health and functional versatility.

[0024] 3. The posture correction device is integrated into the unused space above the desk drawer without damaging the original structure; a gap is left between the drawer front and the base to ensure zero interference when the drawer opens and closes. This structure solves the three major pain points of existing technologies: "drawer interference," "unscientific posture," and "low desktop utilization," and combines health, convenience, and compatibility.

[0041] refer to Figures 1-12This embodiment provides a detachable posture correction device for a desk 3, including a support device 1 and a base 2. The base 2 is detachably installed on the bottom of the desktop 31 of the desk 3, and the base 2 is close to the front side 311 of the desktop 31, which is the side of the desktop 31 facing the user. The support device 1 is detachably connected to the base 2, and the support device 1 stands on the front side 311 of the desktop 31. The support device 1 includes a rotating support 11, a telescopic support 12, and a plate structure 13. The rotating support 11 and the plate structure 13 are respectively installed at both ends of the telescopic support 12, and the plate structure 13 and the rotating support 11 face opposite directions. The base 2 includes a groove structure 21. When the base 2 is installed on the bottom of the desktop 31, the groove structure 21 and the bottom surface of the desk 3 cooperate to form a slot structure 22, and the plate structure 13 is inserted into the slot structure 22 to form a detachable connection.

[0042] The base 2 is fixed to the bottom edge of the desktop 31, forming a slot structure 22 (e.g., Figure 8 The insert plate structure 13 at the bottom of the support device 1 is horizontally inserted into the slot structure 22 to form a detachable rigid connection, preventing the support device 1 from shaking or falling off. During installation, simply align the insert plate structure 13 with the slot structure 22 and push it in horizontally; during disassembly, pull it out in the reverse direction (e.g., ...). Figure 10 The entire process requires no tools and takes less than 3 seconds. In this embodiment, the modular combination of the posture correction device and the desk 3 is achieved through the detachable plug-in structure of the base 2 and the support device 1. This allows for better user convenience in using the desk 3 for other functions (painting, crafts, etc.) without taking up space on the desktop 31. At the same time, it solves the problem of quick removal when the support is not needed, saving tedious steps and making it more convenient for users to use functions such as the drawer 32.

[0043] like Figure 3 The base 2 is made of a magnetically conductive metal material, giving it a magnetic attraction function. Combined with the metal insert structure 13, the insert structure 13 is magnetically secured when inserted into the slotted structure 21, preventing it from sliding out when the desktop is tilted. The base 2 includes mounting portions 23 on both sides of the slotted structure 21; each mounting portion 23 includes mounting holes 24. The base 2 is installed on the bottom of the desktop 31 through the mounting holes 24 and screws 4. A pre-embedded part is embedded in the bottom of the desktop 31 through a hole drilled in it. The base 2 is then locked to the pre-embedded part using countersunk screws 4. The screws 4 provide a more secure lock, the metal base 2 has strong resistance to deformation, and the screw installation ensures long-term load-bearing without loosening.

[0044] The specific structure of the telescopic support 12 provided in this embodiment is as follows: Figure 2The telescopic support 12 includes a lower tube seat 121, an upper tube seat 122 sleeved inside the lower tube seat 121, and a locking structure 123. The upper tube seat 122 can slide up and down along the height direction of the lower tube seat 121. The locking structure 123 is used to lock the sliding of the upper tube seat 122. The locking structure 123 can be operated to release the locking of the upper tube seat 122.

[0045] like Figure 2 The locking structure 123 includes a serrated structure 1231 disposed on one side wall of the upper tube seat 122 and a snap button 1232 disposed on the corresponding side wall of the lower tube seat 121. The snap button 1232 includes a snap tooth 1233, which snaps into the serrated structure 1231 to form a locking engagement.

[0046] like Figure 5 The lower tube seat 121 has a mounting groove structure 1211 on its side wall, and a slot 1212 is formed at the location of the mounting groove structure 1211; the snap-on button 1232 is rotatably mounted in the mounting groove structure 1211 via a connecting rod 1213, the connecting rod 1213 being located in the middle of the snap-on button 1232; Figure 7 The latching button 1232 has a latching tooth 1233 at one end and an elastic element 1235 at the other end. The elastic element 1235 is pressed between the latching button 1232 and the mounting groove structure 1211. The position of the latching tooth 1233 of the latching button 1232 corresponds to the position of the groove 1212. When the other end of the latching button 1232 is lifted by the elastic element 1235, the latching button rotates around the connecting rod 1213 so that the latching tooth 1233 engages with the serrated structure 1231. The other end of the latching button 1232 can be pressed to squeeze the elastic element 1235 so that the latching tooth 1233 disengages from the serrated structure 1231.

[0047] The telescopic support 12 utilizes a locking structure 123 consisting of a serrated structure 1231 and a snap-button 1232 to achieve stepless height adjustment (suitable for children and adults). The height can be adjusted with one hand by pressing the button. The upper tube seat 122 and lower tube seat 121 of the telescopic support 12 employ a snap-button telescopic adjustment mechanism. The serrated structure 1231 of the upper tube seat 122 and the snap-button 1232 of the lower tube seat 121 are mechanically interlocked, resulting in a tighter self-locking when bearing weight vertically. When adjusting up and down, pulling the upper tube seat 122 upwards while simultaneously pressing the snap-button 1232 allows for height adjustment, catering to people of different heights (children / adults / elderly), making sitting and writing more comfortable and protecting health.

[0048] Furthermore, the locking teeth 1233 include two contact endpoints 1234, and the pitch of the serrated structure 1231 is 2.5 times the width of the contact endpoints 1234. The dual-endpoint design distributes the biting pressure, avoids single-point wear, and extends service life. The 2.5 times tooth pitch ensures reasonable step distance during adjustment, and the 2.5 times tooth pitch design ensures sufficient biting depth of the locking teeth 1233, preventing accidental slippage.

[0049] like Figure 6 The insert structure 13 provided in this embodiment is specifically made of metal material. The insert structure 13 has rounded edges for quicker insertion and the rounded edges prevent hand injury. The insert structure 13 is installed at the bottom of the lower tube seat 121 by screws 4.

[0050] The rotating support 11 provided in this embodiment is specifically as follows: Figure 4 The rotating support 11 includes a chest support contact pad 111, two rotating seats 112, and a screw structure 113. The screw structure 113 includes a nut 1131. The two rotating seats 112 are fixed to the back of the chest support contact pad 111 at a distance of 33. The upper tube seat 122 includes a bracket 1221. The bracket 1221 is inserted between the two rotating seats 112 at a distance of 33 and is rotatably connected to the chest support contact pad 111 through the screw structure 113. The rotation angle range of the chest support contact pad 111 relative to the bracket 1221 is 0°-65°.

[0051] The chest support contact pad 111 is adjustable from 0° to 65°, adapting to different body shapes. It primarily conforms to the chest for support, accommodating different body types and developmental stages in both males and females, providing greater comfort and ergonomics. The 0°-65° adjustment utilizes a screw structure 113. The chest support contact pad 111 is connected to the upper tube seat 122 via this screw structure. Adjusting the tightness of the nut 1131 allows for angle adjustment from 0° to 65°. The screw structure 113 acts as a pivot and locking element; tightening the nut 1131 fixes the angle, preventing wobble. When the nut 1131 is loosened, the chest support contact pad 111 rotates freely between itself and the screw structure 113, allowing for easy adjustment within the 0°-65° range.

[0052] like Figure 9-12This embodiment also provides a desk 3 equipped with the detachable posture correction device. The desk 3 includes a desktop 31, a drawer 32 and the detachable posture correction device. There is a gap 33 between the drawer 321 and the bottom of the desktop 31. The drawer 321 is used to be operated to pull open or push back the drawer 32. The base 2 is detachably installed on the bottom of the desktop 31 of the desk 3. The base 2 is located within the gap 33 between the drawer 321 and the bottom of the desktop 31.

[0053] During installation, slide the base 2 into the gap above the drawer 32 and use countersunk screws 4 to fix the base 2 to the bottom of the desktop 31. After installation, the drawer 32 can be completely closed. The base 2 is hidden in the gap between the drawer surface 321 and the desktop 31, with no exposed parts. After the support device 1 is inserted, it is perpendicular to the front side 311 of the desktop 31. The posture correction device is integrated into the unused space above the drawer 32 of the desk 3, without damaging the original structure. A gap 33 is reserved between the drawer surface 321 and the base 2 to ensure zero interference when the drawer 32 is opened and closed.

[0054] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
