[0035] like Figure 1-5As shown, a preferred embodiment of a reading support device provided by the invention includes a panel 1, which is suitable for holding knowledge carriers, such as books, electronic tablets, mobile phones and other objects that record learning materials; a support base 2, which is suitable for installing the reading support device on a desktop for use; the panel 1 and the support base 2 are rotatably connected through a hinge block 21, a hinge seat 11 and a rotating shaft 4; an angle locking component, which connects the hinge seat 11 and the hinge block 21, is suitable for maintaining the angle between the panel 1 and the support base 2; and an extension tube 12 is also included, which extends from the hinge seat 11 to a side away from the hinge block 21, and the rotating shaft 4 is penetrated in the extension tube 12. In this embodiment, preferably, the hinge seat 11 is set on the back of the panel 1, the hinge block 21 is set at the top of the support base 2, and the rotating shaft 4 is sequentially inserted into the hinge seat 11 and the hinge block 21 to realize the hinge connection between the panel 1 and the support base 2; in some other embodiments, the hinge seat 11 can also be set at the top of the support base 2, and the hinge block 21 can be set on the back of the panel 1.

[0036] Specifically, the articulated seat 11 includes at least two articulated arms 111 and an articulated slot 115 between the articulated arms 111; the articulated block 21 is connected to the articulated slot 115. In this embodiment, the articulated seat 11 has two articulated arms 111, which are respectively arranged on the left and right sides, and an articulated slot 115 is formed between the two articulated arms 111. The articulated block 21 is rotatably arranged in the articulated slot 115 via the rotating shaft 4.

[0037] The articulated arm 111 is provided with an articulated hole, and the extension tube 12 is located on the side of the articulated arm 111 facing away from the articulated block 21. In this embodiment, the extension tube 12 is provided only on one of the articulated arms 111, and the rotating shaft 4 sequentially connects the articulated arm 111, the articulated block 21, the other articulated arm 111, and the extension tube 12 together from the articulated hole of one of the articulated arms 111 to form an articulated structure.

[0038] Furthermore, the hinge seat 11 also includes a guard plate 112; both ends of the guard plate 112 are respectively connected to a hinge arm 111, which is suitable for increasing the structural strength of the hinge seat 11, thereby further reducing the shaking of the panel 1.

[0039] Furthermore, the articulated arm 111 is provided with an installation guide groove 114, which is located on the inner side of the articulated arm 111, that is, on the side close to the articulated block 21; the support seat 2 is provided with a guide block 211, which cooperates with the installation guide groove 114, so that during installation, it is not necessary to manually align the articulated arm 111 with the rotating shaft 4 hole on the articulated block 21, thereby achieving alignment-free installation, thereby improving installation efficiency. In some other embodiments, as an equivalent technical solution, the installation guide groove 114 can be set on the articulated block 21, and the guide block 211 can be set on the articulated arm 111.

[0040] The installation guide groove 114 specifically includes a guiding section 1141 and a limiting section 1142.

The guiding section 1141 is used to guide the hinge block 21 to be inserted into the hinge seat 11. One function of the limiting section 1142 is to limit the guiding block 211 from moving further into the hinge seat 11, enabling the installer to sense that the shaft holes of the hinge block 21 and the hinge seat 11 are aligned. Another function is to cooperate with the guiding block 211 to further improve the problem of panel 1 shaking.

[0041] The angle locking assembly includes an angle locking member 31 that is movably arranged and is connected to the rotating shaft 4; a first locking portion 116 located on the hinge seat 11, and a second locking portion 212 provided on the hinge block 21. The first locking portion 116, the second locking portion 212, and the angle locking member 31 jointly act to limit the rotation of the rotating shaft 4 and / or the support seat 2. For example, in some embodiments, both the first locking portion 116 and the second locking portion 212 are grooves with multiple strip-shaped openings, such as a "rice" character shape. By inserting the angle locking member 31 into the first locking portion 116 and the second locking portion 212 simultaneously, the tilting angle of the panel 1 is locked.

[0042] The hinge seat 11 is provided with a receiving groove 113, and the opening of the receiving groove 113 faces away from the support seat 2; the extension pipe 12 protrudes from the bottom wall of the receiving groove 113; the angle locking assembly further includes an operating member 32 adapted to separate the angle locking member 31 from the locking portion; the operating member 32 or the angle locking member 31 can be received in the receiving groove 113, which can limit the operating member 32 and / or the angle locking member 31 and also enhance the aesthetics of the product.

[0043] Receiving grooves 113 and extension pipes 12 are provided in both hinge arms 111, and the rotating shaft (4) and / or the angle locking member pass through the extension pipe (12).

[0044] In this embodiment, taking Figure 3 the shown direction as the coordinate direction, a left receiving groove 113 is provided in the left hinge arm 111, and the operating member 32 can be received in the left receiving groove 113. The left receiving groove 113 is connected to the rotating shaft 4 passing through the left extension pipe 12; the right hinge arm 111 is provided with a right receiving groove 113 and a right extension pipe 12. The angle locking member 31 is fixed on the rotating shaft 4, and the angle locking member 31 passes through the right extension pipe 12.

[0045] A first locking portion 116 is provided in the right hinge arm 111, a second locking portion 212 is provided on the hinge block 21, an angle lock 31 is connected to one end away from the operating member 32, and structures cooperating with the first locking portion 116 and the second locking portion 212 are respectively provided on the angle lock 31; when the angle needs to be adjusted, the operating member 32 is pressed to drive the rotating shaft 4 to push the angle lock 31 outward, so that the angle lock 31 is separated from the first locking portion 116, and then the panel 1 is rotated to adjust the tilt angle of the panel 1. In some other embodiments, the operating member 32 and the angle lock 31 are integrally formed, and the operating member 32 has a handle extending outward, and the angle lock 31 is inserted into the first locking portion 116 or separated from the first locking portion 116 through the handle to achieve locking or releasing the tilt angle of the panel 1.

[0046] Due to the existence of the receiving groove 113, the depth of the hinge hole of the hinge arm 111 is shallow, and the contact area with the rotating shaft 4 is small, so the panel 1 is easily subjected to force and shakes. Therefore, an extension tube 12 is arranged in the receiving groove 113 to increase the contact area with the rotating shaft 4, improve the structural stability, and reduce the adverse user experience of the shaking of the reading panel 1.

[0047] The angle lock member 31 is provided with a locking tooth 311; the first locking portion 116 is provided with a fixing tooth engaged with the lock. In this embodiment, the angle lock member 31 is provided with a plurality of locking teeth 311 distributed in an annular shape on one side close to the hinge block 21 to form a locking toothed disk, and the first locking portion 116 is also provided with a plurality of fixing teeth distributed in an annular shape. After the hinge arm 111 rotates with the panel 1, the angle lock member 31 can still be easily engaged with the first locking portion 116.

[0048] In this embodiment, the second locking portion 212 is preferably disposed in a limiting groove of the hinge block 21 , and a limiting platform 312 is disposed on the angle locking member 31 , which is located on a side of the first locking portion 116 close to the hinge block 21 .

[0049] The angle locking assembly also includes an elastic member (not shown in the figure), which is suitable for keeping the angle locking member 31 locked with the locking portion; the operating member 32 and the angle locking member 31 are respectively fixed to the two ends of the rotating shaft 4. In this embodiment, the elastic member is preferably a compression spring, which is arranged between the angle locking member 31 and the right hinge arm 111; the two ends of the rotating shaft 4 are respectively fixedly connected to the angle locking member 31 and the operating member 32, and the angle locking member 31 is disengaged from the first locking portion 116 by pressing the operating member 32, and the compression spring is compressed at the same time. After the panel 1 is rotated to adjust the angle, the external force applied to the operating member 32 is released, and the compression spring releases the potential energy, so that the angle locking member 31 is re-engaged with the first locking portion 116; under the joint action of the angle locking member 31, the first locking portion 116 and the second locking portion 212, the tilting angle of the panel 1 is maintained.

[0050] In this embodiment, the support base 2 includes a middle rod 22, and a hinge block 21 is arranged at the top end of the middle rod 22. The bottom end of the middle rod 22 is connected with a first supporting foot 23 and a second supporting foot 24. The first supporting foot 23 is connected to the middle rod 22, and preferably the first supporting foot 23 and the middle rod 22 are integrally formed; the second supporting foot 24 is rotatably connected to the outer side of the first supporting foot 23, that is, the side away from the middle rod 22, so that the support base 2 has two usage states, namely the first usage state in which the first supporting foot 23 and the second supporting foot 24 are folded together, and the second usage state in which the first supporting foot 23 and the second supporting foot 24 form an angle. In the second usage state, preferably the angle between the first supporting foot 23 and the second supporting foot 24 is 90 degrees, so that the support base 2 forms a cross foot support bracket.

[0051] A reading support device of the utility model is rotatably connected by an articulated block, an articulated seat and a rotating shaft, and the contact area with the rotating shaft is increased by an extension tube of the articulated seat, thereby solving the technical problem that the panel is easy to shake, providing users with a more suitable reading angle, thereby reducing the wrong sitting posture of leaning forward or lowering the head with the upper body, making it easier for users to maintain a comfortable and healthy good sitting posture for a long time, thereby reducing damage to eyesight and cervical spine, and effectively preventing diseases such as myopia, hunchback and spinal curvature.

[0052] The above embodiments only express a part of the implementation methods of the present invention.
