Description

Technical Field

[0002] During study or reading, the height of the book is usually lower than the height of the human eye. Therefore, during long-term reading, the human body will keep lowering the head, causing the spine to be bent for a long time, which will lead to spinal deformation or myopia, affecting students' vision and normal physical development in the long run. If the degree of spinal curvature needs to be reduced, the book needs to be lifted up to the same level as the human eye, so that the user can read the content of the book conveniently.

[0003] In the prior art, a support plate is usually used to support books, and in order to facilitate reading by users, the support plate is usually set to an inclined form, so that users can conveniently read the content on the display board by adjusting the angle of the support plate. In the reading board in the prior art, it is often necessary to set a support structure supported on the desktop on the back of the support plate to achieve the adjustment of the inclination angle of the support plate. For users of different body shapes, the range of adaptability of this method of adjusting the inclination angle of the support plate is usually relatively limited.

In actual use, the height position of the support plate 1 in the sitting height direction is adjusted by adjusting the retractability of the retractable end 45. At the same time, by adjusting the controllable rotating member between the retractable end 45 and the support plate 1, not only the inclination angle of the support plate 1 can be flexibly adjusted, so that the books located in the bearing area 11 can face the visual range of the human body, but also the relative position between the support plate 1 and the support frame 4 can be locked after adjusting the inclination angle of the support plate 1, so that the support plate 1 can stably carry the load of the book.

[0047] The controllable rotating component includes a rotating support 2 and a locking rod 3. The locking rod 3 extends in the direction of the central axis of the first through hole 44, and the locking rod 3 can slide through the first through hole 44, and at the same time, both ends of the locking rod 3 extend out of both sides of the first through hole 44, so as to facilitate the installation and cooperation between the rotating support 2 and the locking rod 3. The rotating support 2 is arranged on the outer wall surface of the support plate 1 away from the bearing area 11. At the same time, the rotating support 2 is rotatably connected to the two ends of the locking rod 3, so that the rotating support can rotate relative to the locking rod 3 with the support plate 1, thereby adjusting the inclination angle of the support plate 1. In addition, at least one locking assembly is arranged on one end of the locking rod 3 along the central axis of the first through hole 44, which is used to lock the rotating support 2 relative to the telescopic end 45 after rotation, thereby ensuring that the support plate 1 can stably bear the weight of the schoolbag.

[0048] It is worth noting that in the preferred embodiment of the present application, the first direction is parallel to the horizontal plane and is the extension direction of the first through hole 44. The second direction is the height direction of the sitting human body, and the second direction is perpendicular or vertical to the horizontal plane. The third direction is the direction perpendicular to the first direction in the horizontal plane.

[0049] Furthermore, if Figure 6 and Fig. 9 As shown in , in a preferred embodiment of the present application, in order to realize the rotational cooperation between the locking rod 3 and the rotating support 2, an annular surface is provided at both ends of the locking rod 3. Accordingly, both sides of the rotating support 2 are U-shaped supports provided with second through holes 24. Preferably, the U-shaped support includes two single-sided supports 3 spaced apart along the first direction, and the single-sided supports 3 are provided with second through holes 24 extending along the first direction. In actual use, the locking rod 3 extends along the first direction and passes through the two single-sided supports 3 in sequence until the annular surfaces at both ends of the locking rod 3 can respectively cooperate with the second through holes 24 located on the single-sided supports 3, thereby forming a rotational connection between the locking rod 3 and the rotating support 2. Preferably, the annular surface is attached to the inner wall surface of the second through hole 24. Further preferably, there is a clearance fit between the annular surface and the inner wall surface of the second through hole 24.

[0050] More preferably, if Figure 6 , Figure 8 and Fig. 9As shown in , in a preferred embodiment of the present application, the locking assembly includes at least one locking tooth 31 and a plurality of locking grooves 26. Among them, each locking tooth 31 is arranged on an annular surface, and correspondingly, each locking groove 26 is evenly arranged on the inner wall surface of the second through hole 24 along the circumferential direction. Preferably, the annular surface is arranged on the side wall surface of the locking rod 3 close to the end, and at the same time, the locking tooth 31 is also arranged on the end of the annular surface close to the locking rod 3, and correspondingly, a plurality of locking grooves 26 are evenly arranged on the inner wall surface of the second through hole 24 along the circumferential direction. In actual use, if it is necessary to adjust the angle of the support plate 1, the locking rod 3 is pushed so that the locking rod 3 slides in the first through hole 44, driving the locking tooth 31 on the first locking rod 3 to slide out of the locking groove 26, releasing the lock between the locking rod 3 and the rotating support 2, and then the angle of the support plate 1 can be adjusted by rotating the support plate 1. However, after the angle adjustment of the support plate 1 is completed, the locking rod 3 is pulled to slide in the first through hole 44, so that the locking tooth 31 located on the first locking rod 3 is embedded in the corresponding locking groove 26, thereby completing the stable limiting of the locking rod 3 and the rotating support 2.

[0051] Of course, in another preferred embodiment of the present application, each locking tooth 31 is disposed on the inner wall surface of the second through hole 24 , and correspondingly, each locking groove 26 is disposed on the annular surface of the locking tooth 31 .

[0055] Furthermore, the cross-sectional form of the locking rod 3 and the first through hole 44 is not limited to the above-mentioned structural form. In another preferred embodiment of the present application, the cross-sectional shape of the rod body between the two annular surfaces of the locking rod 3 is circular, and correspondingly, the cross-sectional shape of the first through hole 44 is also circular. In order to prevent the locking rod 3 from rotating in the first through hole 44, a plurality of positioning components extending along the first direction are provided between the first through hole 44 and the locking rod 3, for locking the rotation between the locking rod 3 and the first through hole 44. Preferably, a plurality of groups of positioning components are arranged at intervals along the circumferential direction between the locking rod 3 and the positioning rod.

In actual use, the locking rod 3 reciprocates along the first direction relative to the first through hole 44, and at the same time, the positioning block 33 also reciprocates along the first direction in the positioning groove 42, so that during the reciprocating motion of the locking rod 3, the relative rotation between the locking rod 3 and the first through hole 44 can always be limited, and through the arrangement of the positioning block 33 and the positioning groove 42, the load of the rotating support 2 can be transferred to the first through hole 44 through the positioning block 33 and the positioning groove 42, thereby ensuring the stable support of the support frame 4 to the support plate 1.

During actual use, the rotating support 2 rotates relative to the telescopic end 45, and at the same time, the arc-shaped limit hole 25 rotates relative to the limit rod 43 until the end of the arc-shaped limit hole 25 abuts against the limit rod 43, thereby realizing the limitation of the rotation of the rotating bracket.

[0060] Further preferably, in the preferred embodiment of the present application, the central angle of the arc line corresponding to the arc-shaped limiting hole 25 is 30 degrees to 90 degrees.
