Description

Technical Field

[0001] This utility model relates to the field of sketching table technology, and more specifically to a mobile, foldable sketching table for teacher training. Background Technology

[0002] The sketching table plays a vital role in art creation. It provides painters with a stable platform, allowing them to focus on the painting itself without worrying about moving the paper or canvas. It is not only an important tool for painters to sketch outdoors or paint indoors, but also an indispensable part of the artistic creation process.

[0003] Currently available sketching tables have some design shortcomings, especially in terms of user experience. First, these tables are usually not angle-adjustable, which means that artists have to maintain a fixed posture to complete their work. Over time, this may cause physical discomfort or even health problems. For example, when it is necessary to observe the object from different angles or change the painting angle, since the table itself cannot tilt or rotate, the user must frequently move their position to adapt to the needs. This not only increases the complexity of operation but also affects the smoothness and efficiency of creation.

[0004] Secondly, for painters who prefer to use large canvases, many existing sketching tables are too small to support the entire painting. In this case, if a large painting is laid flat on the table, it is easy to not be able to fully display its contents due to space limitations. Alternatively, in order to leave enough work area for the canvas, some tabletop area must be sacrificed to place other tools and materials, which further reduces the actual usable work surface.

[0005] Therefore, in order to solve the above problems, this application provides a mobile, foldable sketching table for teacher training. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a mobile foldable sketching table for teacher training, so as to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a mobile foldable sketching table for teacher training, including a desktop component and a rotating adjustment component installed at the bottom of the desktop component, a placement component installed below the rotating adjustment component, and a sliding component and a fixing component installed on the desktop component;

[0008] Preferably, the desktop assembly includes a left tabletop, a right tabletop, and a main tabletop, wherein the left tabletop and the right tabletop are on the same plane and are attached to the main tabletop.

[0009] Preferably, the rotation adjustment assembly includes a mounting block, a first fixing screw, an adjusting ring, a connecting piece, a first snap-fit ​​block, a first rotating column, a second snap-fit ​​block, a square hole, a retainer, a through hole, and a hexagonal nut. The mounting block is fixedly mounted to the bottom of the main tabletop by the first fixing screw. The second snap-fit ​​block has a square hole. The adjusting ring is fixedly mounted below the mounting block and snaps into the square hole. The adjusting ring has a through hole. The connecting piece is fixedly mounted to the bottom of the mounting block. The first snap-fit ​​block is fixedly mounted below the connecting piece. The second snap-fit ​​block is rotated by the first rotating column. The first locking block is engaged with the rotating locking block, and the hexagonal nut is fixedly engaged with the side wall of the second locking block. The threaded end of the retainer passes through the second locking block and the through hole and is threadedly engaged with the hexagonal nut. At this time, the retainer can be rotated outward to make it no longer engaged with the through hole and the second locking block. At this time, the mounting block and the components mounted above the mounting block rotate along the engagement point of the first locking block and the second locking block. The angle can be adjusted from 180° to 90° horizontally. When adjusted to the appropriate position, the retainer is rotated inward to make it engage with the second locking block and the through hole again and the hexagonal nut is threadedly engaged to fix it.

[0010] Preferably, the placement assembly includes a first support post, a second support post, a second fixing screw, a connecting post, an upper placement plate, and a lower placement plate. The first and second support posts are fixedly installed on both sides of the second snap-fit ​​block, the second snap-fit ​​block is fixedly snapped into the connecting post, the connecting post is fixedly installed between the first and second support posts, the lower placement plate is fixedly installed between the second snap-fit ​​blocks by the second fixing screw, and the lower placement plate is fixedly installed between the connecting post by the second fixing screw. In this case, the upper and lower placement plates, which are fixedly installed between the second snap-fit ​​block and the connecting post by the second fixing screw, can store paintbrushes or other drawing tools.

[0011] Preferably, the sliding assembly includes a sliding groove, a pulley, a transmission rod, and a second rotating column. The sliding groove is fixedly installed on the side wall of the main table panel. The pulley is rotatably sleeved on the lower end of the transmission rod and slidably connected to the sliding groove. The second rotating column is fixedly installed on the side walls of the left and right table panels. The second rotating column is rotatably sleeved on the upper end of the transmission rod. At this time, the left and right table panels are pushed outward, and the pulley slides outward along the sliding groove until the left and right table panels are fixedly engaged with both sides of the main table panel by the transmission rod.

[0012] Preferably, the fixing component includes a fixing claw, a fixing block, and a fixing arm. The lower side of the fixing claw is fixedly installed on the side wall of the left table. The fixing block is engaged with the gripper above the fixing claw. The right end of the fixing arm is movably engaged with the right table. The right end of the fixing arm is fixedly connected to the fixing block. At this time, rotating the fixing arm causes the fixing block, which is fixedly connected to the fixing arm, to disengage from the gripper above the fixing claw.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] When using this sketching table, rotate the retainer outward. At this time, the mounting block and the parts mounted on the mounting block rotate along the first rotating column. The angle can be adjusted from 180° to 90° horizontally. When adjusted to the appropriate position, rotate the retainer inward to fix it, which greatly facilitates the orientation adjustment during sketching. When using some larger canvases, rotate the fixing arm to disengage the fixing block fixedly connected to the fixing arm from the clamp above the fixing claw. At this time, push the left and right table panels outward. The pulleys slide outward along the slide groove until the left and right table panels are fixedly engaged with the sides of the main table panel through the transmission rod, which greatly improves the adaptability of the sketching table to canvases of different sizes.

[0027] The working principle of this utility model is as follows: When using this sketching table, the fixing device 209 can be rotated outward to deactivate it from the through hole 210 and the second locking block 207. At this time, the mounting block 201 and the components mounted on or above the mounting block 201 rotate along the locking points of the first locking block 205 and the second locking block 207. The angle can be adjusted from 180° to 90° horizontally. When adjusted to the appropriate position, the fixing device 209 can be rotated inward to reactivate it from the second locking block 207 and the through hole 210, and the hexagonal nut 211 can be threaded onto it to fix it in place. The upper placement plate 305 and lower placement plate 306, which are fixedly installed between the second locking block 207 and the connecting post 304 by the second fixing screw 303, can store paintbrushes or other painting tools. When a larger canvas is needed, the fixing arm 503 is rotated to disengage the fixing block 502, which is fixedly connected to the fixing arm 503, from the clamp above the fixing claw 501. At this time, the left table 101 and the right table 102 are pushed outward, and the pulley 402 slides outward along the slide groove 401 until the left table 101 and the right table 102 are fixedly locked to both sides of the main table 103 by the transmission rod 403.
