Abstract
Description
Technical Field
[0001] This utility model relates to a learning product, specifically a study table. Background Technology
[0002] As a core component of children's and teenagers' learning environment, the study desk plays a crucial role in optimizing learning posture and improving comfort through ergonomic design, while also adapting to height changes at different ages. The tilt design of the study desk (typically 0°-40°) allows for adjustment of the book's viewing angle, reducing forward head posture, relieving spinal pressure, and preventing hunchback and myopia. Most products also feature separate writing, reading, and storage areas, maximizing space utilization.
[0003] However, the current design of the posture correction structure on study desks is unreasonable. Not only is it inconvenient to fold it under the desk surface, making it difficult to carry, but it also tends to tilt forward when in close contact with the user, failing to provide effective posture correction (e.g., ...). Figure 7 (As shown in the image), in addition, the design of the book board structure for placing books and tablets is not reasonable enough. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this utility model is to provide a study desk.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a study desk, comprising a desk body and triangular frames symmetrically arranged on the left and right sides of the desk body. The triangular frames form an inclined surface that gradually rises from the front end to the rear end of the desk body. The front edge of the desk body extends downward and forward, and is provided with symmetrical and spaced-apart cavity structures. Each cavity structure has a plate-shaped fixing limiting plate fixed inside it. The fixing limiting plate has a hollow opening in its center, and an elastic limiting plate extending from the fixing limiting plate is provided on one side of the hollow opening. A posture correction pivot is located between the left and right cavity structures, and the outer center of the posture correction pivot is fixed with a penetrating cavity structure. The side wall of the structure has a limiting shaft, and each side limiting shaft has multiple inwardly recessed semi-cylindrical limiting grooves evenly distributed on its circumferential surface. The elastic outer end surface of the elastic limiting plate is provided with a semi-cylindrical limiting protrusion that protrudes from the elastic limiting plate. The limiting protrusion is locked in one of the limiting grooves of the corresponding side limiting shaft. A telescopic sleeve is fixed at the center of the circumferential side wall of the posture correction rotating shaft. A posture correction pad facing the rear is fixed at the outer end of the telescopic sleeve, and the telescopic sleeve is in a vertical position facing upward. A limiting stop edge is provided on the upper side of the posture correction rotating shaft, which is close to the front edge of the table body. The limiting stop edge blocks the posture correction rotating shaft, preventing the posture correction rotating shaft from continuing to rotate towards the table body.
[0006] Furthermore, a long, hollowed-out handle structure is provided at the center of the rear surface of the tabletop body. A long, symmetrically recessed bookplate slot is provided on the inner side of the tabletop body surface of the handle structure. Long cylindrical fixing posts with long cross-sections are provided on both sides of the lower front end of the bookplate and the lower back end of the bookplate, and each cylindrical fixing post is inserted into the handle structure and the bookplate slot respectively.
[0007] Furthermore, multiple barbed structures forming the shape of a book board are evenly fixed to the lower surface of the tabletop body between the triangular frames, allowing the book board to be secured to the lower surface of the tabletop body via the barbed structures.
[0008] Furthermore, the bottom of the book board is bent to form a tray for placing the bottom of the book. Two cylindrical fixing pins on the front side are located on the lower surface of the tray, and the surface of the tray above the cylindrical fixing pins is provided with a downwardly recessed clamping block placement groove. The tray between the clamping block placement grooves is provided with an upwardly protruding book guard edge. Book clamping springs are fixed in the clamping block placement grooves on each side, and the upper end of the book clamping springs is in close contact with the surface of the table board body.
[0009] Furthermore, the telescopic sleeve is provided with a limiting structure for limiting the length of the telescopic sleeve, and a T-shaped correction plate fixing plate is fixed to the upper end of the telescopic sleeve, and the sitting posture correction pad is fixed on the front side of the horizontal part of the correction plate fixing plate.
[0010] Furthermore, each side clamping block has a spring clip fixing block fixed at the bottom of its placement slot, and the spring clip fixing block has an inclined slot for inserting the lower end of the book clamping spring clip.
[0011] Furthermore, the main surface of the tabletop on the front side between the bookplate slots is provided with a downwardly recessed, elongated pen holder slot.
[0012] Furthermore, both the main body of the tabletop and the back of the book board are equipped with raised mesh reinforcing ribs.
[0013] Furthermore, the lower edge of the tabletop body is provided with a long, narrow notch structure.
[0014] With the above settings, this utility model has the following advantages: 1. The tabletop body of this utility model is symmetrically provided with triangular frames on the left and right sides. The triangular frames make the tabletop body form an inclined surface that gradually rises from the front end to the rear end. The triangular frames are fixed to the tabletop body by an inlay fixing method, which can greatly improve the strength of both sides of the tabletop body, thereby improving the strength of the tabletop body and making it more sturdy and durable. 2. The front edge of the tabletop body of this utility model extends downward and forward, forming a symmetrical and spaced cavity structure. This not only facilitates the accommodation of the limiting shafts at both ends of the posture correction pivot and the limiting structure for limiting the shafts, but also forms a retaining edge structure that is locked on the front edge of the tabletop, limiting and positioning the entire tabletop body and preventing the tabletop body from sliding due to forward force when in use, thus making it more stable during use. 3. The peripheral surfaces of the limiting shafts on each side of this utility model are evenly provided with multiple inwardly recessed semi-cylindrical limiting grooves. The elastic outer end surface of the elastic limiting plate is provided with a semi-cylindrical limiting protrusion that protrudes from the elastic limiting plate. The limiting protrusion is locked in one of the limiting grooves of the corresponding limiting shaft, forming a simple structure that is easy to adjust the rotation and positioning of the posture correction shaft, and is convenient to adjust the position of the posture correction pad when folding and when opening for use. 4. The limiting edge of this utility model blocks the posture correction rotating shaft, preventing it from continuing to rotate towards the main body of the table. The limiting edge provides a good limiting effect, which can more firmly support the chest and prevent students from lying on the main body of the table when using it, thus improving the posture correction effect. 5. This utility model makes it easy to fully fit the posture correction cushion onto the lower surface of the tabletop body for folding, while the book board can be secured to the lower surface of the tabletop body via a hook structure. This not only makes it easy to carry, but also makes it smaller in size after folding, which is convenient for transportation and logistics packaging. 6. The handle structure of this utility model can not only be used for carrying, but also as a fixing hole. It forms a stable triangular insertion structure with the two book plate slots on the front side, which can effectively improve the fixing strength of the book plate, thus making it more secure when placing books or tablets.

[0018] The following is a detailed description of this embodiment with reference to the accompanying drawings: This embodiment provides a study table, please refer to the accompanying drawings in the instruction manual. Figure 1-6 .
[0019] like Figure 1-6As shown, a study desk includes a desk body 1 and triangular frames 2 symmetrically arranged on the left and right sides of the desk body 1. The triangular frames 2 make the desk body 1 form an inclined surface that gradually rises from the front end to the rear end. The front edge of the desk body 1 extends downward and forward, and is provided with symmetrical and spaced-apart cavity structures 3. Each cavity structure 3 has a plate-shaped fixing limiting plate 4 fixed inside it. The fixing limiting plate 4 has a hollow opening in its center. An elastic limiting plate 5 extending from the fixing limiting plate 4 is provided on one side of the hollow opening. A posture correction pivot 6 is located between the left and right cavity structures 3, and the outer center of the posture correction pivot 6 is fixed with a limiting shaft 7 that penetrates the side wall of each cavity structure 3. The periphery of each limiting shaft 7 has multiple inwardly recessed semi-cylindrical limiting lines evenly distributed. The groove 8, such as four limiting grooves 8 evenly arranged on each limiting shaft 7, can complete one positioning by rotating 90 degrees each time. The elastic outer end surface of the elastic limiting plate 5 is provided with a semi-cylindrical limiting protrusion 27 protruding from the elastic limiting plate 5. The limiting protrusion 27 is stuck in one of the limiting grooves 8 of the corresponding limiting shaft 7. The center of the peripheral side wall of the posture correction rotating shaft 6 is fixed with a telescopic sleeve 9, such as the telescopic structure used in the prior art. The outer end of the telescopic sleeve 9 is fixed with a posture correction pad 10 facing the rear side, and the telescopic sleeve 9 is in a vertical state facing upward. The upper side of the posture correction rotating shaft 6 is provided with a limiting stop 11 that is close to the front edge of the table body 1. The limiting stop 11 blocks the posture correction rotating shaft 6, so that the posture correction rotating shaft 6 cannot continue to rotate towards the table body 1.
[0020] For ease of carrying, a long, hollowed-out handle structure 12 is provided at the center of the rear surface of the tabletop body 1. A long, symmetrically recessed book plate slot 13 is provided on the inner side of the tabletop body 1. Long cylindrical fixing posts 15 with long cross-sections are provided on both sides of the lower front end of the book plate 14 and the lower back end of the book plate. Each cylindrical fixing post 15 is inserted into the handle structure 12 and the book plate slot 13 respectively. In addition, multiple barbed structures 16 that surround the shape of the book plate 14 are evenly fixed on the lower surface of the tabletop body 1 between the triangular frames 2. The book plate 14 can be locked onto the lower surface of the tabletop body 1 through the barbed structures 16, further reducing the overall volume and making it easier to carry. A long, notched structure 26 is provided on the downward-bent edge of the rear end of the tabletop body 1. Both the tabletop body 1 and the book plate 14 have raised mesh reinforcing ribs 25 on their backs to further improve the strength of the tabletop body 1 and the book plate 14.
[0021] The bottom of the book plate 14 is bent to form a support plate 17 for placing the bottom of the book. Two cylindrical fixing posts 15 on the front side are located on the lower surface of the support plate 17. The surface of the support plate 17 above the cylindrical fixing posts 15 is provided with a downwardly recessed clamping block placement groove 18. The support plate 17 between the clamping block placement grooves 18 is provided with an upwardly protruding book guard edge 19. Book clamping springs 20 are fixed in each clamping block placement groove 18. The upper end of the book clamping springs 20 is in close contact with the surface of the table body 1. Spring fixing blocks 22 are fixed at the bottom of each clamping block placement groove 18. The spring fixing blocks 22 are inclined and have slots 23 for inserting the lower end of the book clamping springs 20. The surface of the table body 1 on the front side between the book plate slots 13 is provided with a downwardly recessed long strip pen placement groove 24. Book clamping springs 20 made of transparent plastic or steel sheet are used to hold open books.
[0022] The telescopic sleeve 9 is provided with a limiting structure for limiting the length of the telescopic sleeve 9, and a T-shaped correction plate fixing plate 21 is fixed at the upper end of the telescopic sleeve 9. The sitting posture correction pad 10 is fixed on the front side of the horizontal part of the correction plate fixing plate 21.
[0023] The working principle of this utility model is as follows: When the posture correction pad 10 needs to be folded and fastened to the lower surface of the table body 1, the posture correction pivot 6 is rotated to make each limiting pivot 7 rotate, thereby forcing the limiting protrusion 27 to gradually disengage from the original engaging limiting groove 8 until it "clicks" into the next limiting groove 8. This continues until the posture correction pad 10 is completely attached to the lower surface of the table body 1 and the folding is completed. The book board 14 can be fastened to the lower surface of the table body 1 by the barbed structure 16. This not only makes it easy to carry, but also makes the folded size smaller and easier to transport and pack. When in use, simply insert the book board 14 into the rear surface of the tabletop body 1, and rotate the posture correction pad 10 to open it. Since the telescopic sleeve 9 is in an upward and vertical position, the upper side of the posture correction pivot 6 is provided with a limiting stop 11 that is close to the front edge of the tabletop body 1. The limiting stop 11 blocks the posture correction pivot 6, preventing the posture correction pivot 6 from continuing to rotate towards the tabletop body 1. The limiting stop 11 can form a good limiting effect, which can more firmly support the chest and prevent students from lying on the tabletop body 1 when using it. In addition, the handle structure 12 can not only be used for carrying, but also as a fixing hole, forming a stable triangular insertion structure with the two book plate slots 13 on the front side, which can effectively improve the fixing strength of the book plate, thus making it more secure when placing books or tablets.
[0024] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
