Technical Field

[0001] The utility model relates to the technical field of learning supplies, in particular to a bookshelf for correcting sitting posture for reading. Background Art

[0002] Reading is the process of acquiring information from visual materials; visual materials are mainly text and pictures, but also include symbols, formulas, charts, etc. When students read books, they usually place the books on the table to read, but this way of reading can easily cause students fatigue. If the sitting posture is not correct, it can also cause damage to the students' neck and spine. Therefore, the emergence of reading bookshelves solves this problem.

[0003] The relevant patent publication number is: CN213798916U, which discloses a suction cup bookshelf for Chinese reading in secondary vocational schools that can correct sitting posture. It not only improves the stability of the suction cup bookshelf during use, but also improves the convenience of using the suction cup bookshelf, and also facilitates correcting the reader's sitting posture when using the suction cup bookshelf.

[0004] The reading bookshelf in the above-mentioned prior art occupies a large space on the desktop when in use, which results in the need to store the books and other items on the desktop before use, which is poor in practicality, and the suction cup is difficult to remove after use, which is inconvenient to operate. Therefore, we propose a reading bookshelf that corrects the sitting posture. Utility Model Content

[0025] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0026] Example:

[0027] like Figure 1-Figure 5 As shown, a bookshelf for correcting sitting posture reading comprises a fixed seat 1, a fixing assembly 4 is fixedly connected to the bottom of the fixed seat 1, a reading mechanism 2 is fixedly connected to the top of the fixed seat 1, and a placement board 3 for placing books is arranged on the left side of the reading mechanism 2;

[0028] The reading mechanism 2 includes a rectangular rod 211, which is fixedly connected to the top of the fixed seat 1. A rectangular sleeve 201 is slidably connected to the outer side of the rectangular rod 211. A rotating shaft 205 is movably connected to the left side of the rectangular sleeve 201 through a bearing. A limiting bolt 202 is arranged on the right side of the rectangular sleeve 201. A movable ring 209 is slidably connected to the outer side of the rotating shaft 205. A limiting rod 208 is fixedly connected to the right side of the movable ring 209.

[0029] The working principle of the above technical solution is as follows:

[0030] After the limit of the limit bolt 202 is cancelled, the height of the placement plate 3 can be adjusted under the action of the rectangular sleeve 201 and the rectangular rod 211. The pull block 204 is pulled to move the limit rod 208 out of the limit hole 203. At this time, the inclination angle of the placement plate 3 can be adjusted. Under the action of the placement plate 3, the reading mechanism 2 and the fixing component 4, the placement plate 3 is suspended in the air, so there is no need to move the books on the desktop. After adjusting to the appropriate angle, students can correct their sitting posture when reading.

[0031] In another embodiment, if Figure 3 As shown, a screw hole is opened on the right side of the rectangular sleeve 201 , and the limiting bolt 202 is threadedly connected to the inner side of the screw hole, and the left end of the limiting bolt 202 is tightly fitted with the outer side of the rectangular rod 211 .

[0032] Under the action of the limiting bolt 202, the position of the rectangular sleeve 201 outside the rectangular rod 211 can be limited, so that the height of the placement plate 3 can be adjusted to make it suitable for students of different heights.

[0033] In another embodiment, if Figure 3 As shown, a slide groove 207 is provided on the outer side of the rotating shaft 205 , a slider 210 is fixedly connected to the inner side of the movable ring 209 , and the slider 210 is slidably connected to the inner side of the slide groove 207 .

[0034] Under the action of the slide groove 207 and the slider 210, the moving track of the movable ring 209 can be limited to ensure that it can only move in the left and right directions, thereby limiting the placement plate 3 after the position is adjusted.

[0035] In another embodiment, if Figure 1 As shown, the placement plate 3 is fixedly connected to the left end of the rotating shaft 205 , a spring 206 is fixedly connected to the right side of the placement plate 3 , and the spring 206 is fixedly connected to the left side of the movable ring 209 .

[0036] The rotating shaft 205 fixes and supports the placement plate 3 , and the spring 206 allows the limiting rod 208 to easily enter the limiting hole 203 to limit the position of the rotating shaft 205 .

[0037] In another embodiment, if Figure 3 As shown, a limiting hole 203 is opened on the left side of the rectangular sleeve 201, and the limiting holes 203 are distributed in a ring shape on the left side of the rectangular sleeve 201. The inner side of the limiting hole 203 is adapted to the outer side of the limiting rod 208, and a pull block 204 is fixedly connected to the outer side of the movable ring 209.

[0038] The position of the placement plate 3 after rotation can be limited by the limiting rod 208 and the limiting hole 203 , and the movable plate can be conveniently pulled to move by the pulling block 204 , so as to adjust the inclination angle of the placement plate 3 .

[0039] In another embodiment, if Figure 4 As shown, the fixing assembly 4 includes a threaded block 401, which is fixedly connected to the bottom of the fixing seat 1. The outer side of the threaded block 401 is threadedly connected to an internal threaded tube 403, the bottom end of the internal threaded tube 403 is fixedly connected to a U-shaped plate 402, a bottom plate 404 is arranged on the inner side of the U-shaped plate 402, and a threaded rod 405 is movably connected to the bottom of the bottom plate 404 through a bearing.

[0040] The U-shaped plate 402 can be connected to the fixing seat 1 by the action of the threaded block 401 and the internal threaded tube 403, and the edge of the desk can be clamped by the action of the U-shaped plate 402 and the bottom plate 404 to fix the reading stand, and the bottom plate 404 can be driven to move by the action of the threaded rod 405.

[0041] In another embodiment, if Figure 4 As shown, the bottom end of the threaded rod 405 passes through the bottom of the U-shaped plate 402 and is threadedly connected to the bottom of the U-shaped plate 402. The bottom of the bottom plate 404 is fixedly connected to a vertical rod 406. The bottom end of the vertical rod 406 passes through the bottom of the U-shaped plate 402 and is slidably connected to the bottom of the U-shaped plate 402.

[0042] The position of the bottom plate 404 can be adjusted under the action of the threaded rod 405 , and the moving track of the bottom plate 404 can be limited under the action of the vertical rod 406 .

[0043] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
