Description

Technical Field

[0001] This application relates to the field of furniture technology, and in particular to a study table. Background Technology

[0002] A study desk is a new type of scientific, user-friendly, and practical desk and chair designed for students. Depending on the environment in which it is used, study desks are divided into home study desks and school study desks. Currently, to accommodate users of different heights or those at different stages of life, study desks are equipped with adjustable desktop height. In addition, to store books and stationery and prevent them from piling up on the desktop, storage boxes are installed under the desktop to meet the storage needs of learners.

[0003] The existing study table includes a tabletop, a storage box, and a support mechanism. The bottom wall of the tabletop is fixedly connected to the storage box, which is located directly below the tabletop and has an opening on one side. The support mechanism includes two sets of support members, which are located near opposite sides of the tabletop. Each support member includes a base plate on the ground. A tubular shell is fixedly installed on the top of the base plate. A multi-stage electric telescopic rod is fixedly installed inside the tubular shell. A movable rod is fixedly connected to the telescopic end of the multi-stage electric telescopic rod. The top of the movable rod is fixedly connected to the bottom of the tabletop, and the movable rod is slidably connected to the tubular shell.

[0004] In response to the aforementioned issues, prolonged use of study desks can lead to poor posture among students, causing them to unconsciously lean close to textbooks or picture books while studying. This prolonged close-range reading or writing can easily cause nearsightedness, resulting in a gradual decline in the eyesight of teenagers and children, and affecting the effectiveness of the study desk. Summary of the Invention

[0005] To improve the usability of a study desk, this application provides a study desk.

[0006] This application provides a study desk, which adopts the following technical solution: A study desk includes a tabletop, a frame, an ergonomic mechanism, and a support mechanism; The tabletop is mounted on the frame, and the tabletop is located directly above the frame. The engineering mechanism includes a ventral support frame and adjustment components; The frame plate has an open groove on one side for the sliding of the abdominal support frame; the abdominal support frame includes an arc-shaped support rod and two crossbars, the two crossbars are arranged parallel in the length direction, and the crossbars are slidably connected to the frame plate; the ends of the two crossbars away from the inner cavity of the frame plate are fixedly connected to the arc-shaped support rod; The adjustment component is mounted on the frame plate, and the adjustment component is used to drive the abdominal support frame to slide along the open slide groove; The support mechanism is installed on the bottom wall of the frame plate, and the support mechanism is used to support the frame plate.

[0007] By adopting the above technical solution, when the distance between the student and the table needs to be adjusted, the adjustment component is adjusted. The adjustment component drives the abdominal support frame to slide along the open slide groove. The curved support rod of the abdominal support frame moves away from the table, and the distance between the curved support rod and the table meets the student's learning requirements. The student's body is close to the curved support rod while studying textbooks or doing picture book assignments on the table. The ergonomic design facilitates the adjustment of the distance between the curved support rod and the table, thereby limiting the distance between the student's body and the table. This prevents students from unconsciously getting too close to textbooks or picture books while studying, which can lead to a gradual decline in the eyesight of teenagers and children due to prolonged close-range reading or writing, thus improving the effectiveness of the study desk.

[0008] Optionally, the abdominal support frame further includes a barrier bar and a base plate. The barrier bar is installed at the end of the crossbar away from the arc-shaped support rod. The base plate is fixedly connected to the bottom wall of the barrier bar, the arc-shaped support rod, and the two crossbars. The base plate, the barrier bar, the arc-shaped support rod, and the two crossbars form a storage cavity.

[0009] By adopting the above technical solution, the designed barrier bar and base plate can easily form a storage cavity, which facilitates the storage of learning materials or other items.

[0010] Optionally, the adjusting assembly includes a longitudinal screw, a driving bevel gear, two transverse screws, and two driven bevel gears; Both of the transverse screws are rotatably connected to the frame plate, and the two transverse screws are arranged axially parallel. The transverse screws respectively pass through the extensions of the two transverse bars of the barrier bar, and the transverse screws are threadedly connected to the barrier bar. The two driven bevel gears are respectively coaxially fixed on the transverse screw; The longitudinal screw is rotatably connected to the frame plate, and the axial direction of the longitudinal screw is perpendicular to the axial direction of the transverse screw; The driving bevel gear is coaxially fixed on the longitudinal screw, and the driving bevel gear meshes with the driven bevel gear.

[0011] By adopting the above technical solution, rotating the longitudinal screw drives the active bevel gear to rotate. Since the active bevel gear meshes with the driven bevel gear, the active bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the transverse screw to rotate, achieving synchronous rotation of the two transverse screws. Because the transverse screw is threadedly connected to the barrier rod, the transverse screw drives the barrier rod to move along the axial direction of the transverse screw, thereby driving the entire abdominal support frame to move along the axial direction of the transverse screw, realizing the adjustment of the distance between the arc-shaped support rod of the abdominal support frame and the tabletop. The designed adjustment component facilitates the application of force to the abdominal support frame, causing the abdominal support frame to move along the axial direction of the transverse screw, thereby realizing the adjustment of the distance between the arc-shaped support rod of the abdominal support frame and the tabletop. This prevents students from unconsciously getting too close to textbooks or picture books while studying, which can lead to a gradual decline in the eyesight of teenagers and children due to prolonged close-range reading or writing, thus improving the effectiveness of the study desk.

[0012] Optionally, a guide slider is fixedly connected to the wall of the open slide groove, and a guide groove for the guide slider to slide is opened on the side of the two crossbars away from each other, and the guide groove is opened along the length direction of the crossbars.

[0013] By adopting the above technical solution, the designed guide slider and guide groove facilitate the guidance of the crossbar, allowing the crossbar to move along the length of the guide groove. At the same time, it facilitates the support of the crossbar and reduces the deviation of the web support frame caused by excessive force on one end.

[0014] Optionally, the arc-shaped support rod includes an integrally connected arc-shaped part and two limiting parts. The arc-shaped part is positioned opposite the open sliding groove, and the two limiting parts are symmetrically distributed about the arc-shaped part. When the abdominal support frame is in the closed state, the limiting parts are in contact with the outer wall of the frame plate.

[0015] By adopting the above technical solution, the segmented arc-shaped part and the limiting part are used to support the student's body in the learning state, and the limiting part is used to limit the movement path of the abdominal support frame, so as to prevent the abdominal support frame from moving completely into the inner cavity of the frame plate.

[0016] Optionally, the support mechanism includes two sets of support members, which are symmetrically distributed about the web support frame, and the two sets of support members are fixedly installed on opposite side walls of the frame plate. The support components include a support rod, a support sleeve, a support base plate, and an electric telescopic rod; The support rod is fixedly connected to the longitudinal part of the frame plate, and the support rod is perpendicular to the plane of the frame plate. The support sleeve is coaxially sleeved on the support rod, and the support sleeve is slidably connected to the support rod; The electric telescopic rod is installed in the inner cavity of the support sleeve, and the piston rod of the electric telescopic rod is connected to the support rod; The support base plate is installed at the end of the support sleeve away from the support rod.

[0017] By adopting the above technical solution, when the height of the tabletop needs to be adjusted, the electric telescopic rod is adjusted. The piston rod of the electric telescopic rod drives the support rod to slide along the inner cavity of the support sleeve. The support rod drives the frame plate to move, and the frame plate drives the tabletop to move, thereby realizing the lifting and lowering of the tabletop. The designed support mechanism, through the electric telescopic rod, facilitates the vertical lifting and lowering of the tabletop, thereby realizing the height adjustment of the tabletop. This is to accommodate users of different heights or users of different ages who are learning at the same time.

[0018] Optionally, the support further includes a limiting ring and at least one limiting screw. The support base plate is rotatably connected to the support sleeve, and the limiting ring is fixedly sleeved on the support sleeve. The limiting ring is threadedly connected to the limiting screw, and the axial direction of the limiting screw is parallel to the axial direction of the support sleeve. A limiting slot is provided on the top wall of the support base plate for the end of the limiting screw to be inserted.

[0019] By adopting the above technical solution, since the support base plate and the support sleeve are rotatably connected, when the support base plate is installed on the ground and supports the tabletop, support rod, and support sleeve, adjusting the limiting screw will cause the limiting ring and the limiting screw to move downward along the axial direction of the support sleeve. The limiting screw moves until its end is inserted into the limiting slot, thus fixing the support base plate and the support sleeve. The designed limiting ring and limiting screw facilitate the limiting of the support base plate, ensuring that the support base plate and the support sleeve are in a vertical state, achieving stable support for the tabletop, frame, support rod, and support sleeve, thus facilitating the ground installation of the study desk.

[0020] Optionally, the support further includes mounting lugs, connecting lugs, and fixing bolts; the mounting lugs are fixedly connected to the support sleeve, the connecting lugs are fixedly connected to the support base plate, and when the support base plate is rotated to the point where the length direction of the support base plate is parallel to the axial direction of the support sleeve, the mounting lugs are positioned opposite the connecting lugs, and the fixing bolts pass through the mounting lugs and connecting lugs to connect to the wall.

[0021] By adopting the above technical solution, since the support base plate and the support sleeve are rotatably connected, rotating the support base plate allows it to rotate until it is parallel to the length direction of the support sleeve. Then, the fixing bolts are passed through the mounting ears and connecting ears and fixed to the wall, thus realizing the wall-mounted installation of the study desk. The designed mounting ears, connecting ears, and fixing bolts, through the adjustment of the state of the support base plate, make it easy for the support base plate to be in a horizontal or vertical state, thereby facilitating the floor installation or wall-mounted installation of the study desk, expanding the application range of the study desk, and improving its practicality.

[0022] Optionally, the support member further includes an auxiliary support lug, which is fixedly connected to the end of the support sleeve near the support rod, and the fixing bolt passes through the auxiliary support lug and is connected to the wall.

[0023] By adopting the above technical solution, the designed auxiliary support lugs facilitate the connection between the support rod and the wall through fixing bolts, making it easier to further reinforce the study desk in the wall-mounted state and improve the installation effect of the study desk.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The designed study desk uses an ergonomic mechanism to easily adjust the distance between the curved support rod and the tabletop, thereby limiting the distance between the student's body and the tabletop. This prevents students from unconsciously getting too close to textbooks or picture books while studying, which can lead to a gradual decline in the eyesight of teenagers and children due to prolonged close-range reading or writing, thus improving the effectiveness of the study desk. 2. The designed study desk features an electric telescopic rod for the support mechanism, allowing for easy vertical height adjustment of the desktop. This accommodates users of different heights or those at different stages of life. Furthermore, the adjustable support seat allows for both horizontal and vertical positioning, facilitating floor or wall mounting and expanding the desk's applicability and practicality.

One limiting screw 3151 is missing; the support rod 311 is fixedly connected to the longitudinal part of the frame plate 2, and the support rod 311 is perpendicular to the plane where the frame plate 2 is located. In this embodiment, the length direction of the support rod 311 is perpendicular to the plane where the frame plate 2 is located; the support sleeve 312 is coaxially sleeved on the support rod 311, and the support sleeve 312 and the support rod 311 are slidably connected; the electric telescopic rod 314 is installed in the inner cavity of the support sleeve 312, and the piston rod of the electric telescopic rod 314 is connected to the support rod 311.

The connecting lug 317 is fixedly connected to the support base plate 313. In this embodiment, the connecting lug 317 and the support base plate 313 are welded together. When the support base plate 313 is rotated to a state where the length direction of the support base plate 313 is parallel to the axial direction of the support sleeve 312, the mounting lug 316 is positioned opposite the connecting lug 317. The fixing bolt 319 passes through the mounting lug 316 and the connecting lug 317 and connects to the wall. The auxiliary support lug 318 is fixedly connected to the end of the support sleeve 312 near the support rod 311. In this embodiment, the auxiliary support lug 318 is welded together with the support sleeve 312, and the fixing bolt 319 passes through the auxiliary support lug 318 and connects to the wall.

[0033] The implementation principle of the study desk in this embodiment is as follows: When the distance between the user and the desk 1 needs to be adjusted during use, the handle is rotated. The handle drives the longitudinal screw 431 to rotate synchronously, and the longitudinal screw 431 drives the active bevel gear 432 to rotate synchronously. Since the active bevel gear 432 meshes with the driven bevel gear 433, the active bevel gear 432 drives the driven bevel gear 433 to rotate, and the driven bevel gear 433 drives the transverse screw 434 to rotate synchronously, thus achieving synchronous rotation of the two transverse screws 434. The transverse screw 434 is threadedly connected to the barrier rod 423. The transverse screw 434 drives the barrier rod 423 to move along the axial direction of the transverse screw 434, which in turn drives the entire abdominal support frame 42 to move along the axial direction of the transverse screw 434. This allows for adjustment of the distance between the arc-shaped support rod 421 of the abdominal support frame 42 and the table 1. The distance between the arc-shaped support rod 421 of the abdominal support frame 42 and the table 1 is adjusted to meet the students' learning requirements. Students can then use the arc-shaped support rod 421 to study textbooks or do picture book assignments on the table 1.

[0034] When the height of the tabletop 1 needs to be adjusted, the electric telescopic rod 314 is adjusted. The piston rod of the electric telescopic rod 314 drives the support rod 311 to slide along the inner cavity of the support sleeve 312. The support rod 311 drives the frame plate 2 to move, and the frame plate 2 drives the tabletop 1 to move, thereby realizing the raising and lowering of the tabletop 1.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
