Description

Technical Field

[0001] The utility model relates to the technical field of sitting posture correction, and more specifically, to an improvement of a telescopic rod of a sitting posture corrector. Background Art

[0002] During the learning process, students often bend their waists, necks or lie on the table to read. If they maintain this incorrect sitting posture for a long time, it will cause problems such as spinal deformity or myopia, which will affect the students' eyesight and normal physical development in the long run. Therefore, it is particularly important to ensure the correct sitting posture of students during the learning process.

[0003] In view of problems such as hunchback, myopia and cervical spondylosis of users, in order to enable users to maintain a good sitting posture, a sitting posture corrector is installed on the learning tabletop, and a limiting structure is formed by the sitting posture corrector. The limiting structure is used to limit the degree of the user's head-down and bending, so as to achieve the purpose of correcting the sitting posture. Although the existing sitting posture correctors can solve the problem that users are prone to bend their waists and lower their heads when reading books and using electronic devices, they are relatively inconvenient to use. The height adjustment of the corrector is complex and cannot adapt to adjust the height of the chest rest according to the height of the user. Summary of the Utility Model

[0024] To further illustrate the embodiments, the present utility model provides drawings, which are part of the disclosure of the present utility model. They are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present utility model, there is provided a sitting posture corrector with an anti-detachment telescopic rod.

[0026] Now, the present utility model will be further described in conjunction with the drawings and specific embodiments. As Figures 1-5 shown, a sitting posture corrector with an anti-detachment telescopic rod according to an embodiment of the present utility model includes a writing board 2, a telescopic support rod 1 and a chest rest 3. The telescopic support rod 1 is connected to the side end of the writing board 2, and the chest rest 3 is arranged at the upper end of the telescopic support rod 1. The telescopic support rod 1 is sequentially inserted and connected by a first sleeve rod 11, a second sleeve rod 12, a third sleeve rod 13 and a fourth sleeve rod 14. Inner convex rings 5, convex platforms 6, card holes 7 and one-way cards 8 are arranged on the first sleeve rod 11, the second sleeve rod 12, the third sleeve rod 13 and the fourth sleeve rod 14. The inner convex ring 5 and the convex platform 6 are movably and limit-connected. The card hole 7 is arranged on one side of the convex platform 6, and the one-way card 8 is arranged on the other side of the convex platform 6. Thus, a limiting effect is achieved, and the problem of cross-bar contraction is solved.

[0027] In one embodiment, the sizes of the first sleeve rod 11, the second sleeve rod 12, the third sleeve rod 13 and the fourth sleeve rod 14 are from small to large and are connected in cooperation. Thus, the telescopic or stretching of the first sleeve rod 11 to the fourth sleeve rod 14 is realized.

[0028] In one embodiment, four groups of the inner convex rings 5 are respectively arranged above the inner sides of the first sleeve rod 11, the second sleeve rod 12, the third sleeve rod 13 and the fourth sleeve rod 14. The inner convex ring 5 and the convex platform 6 are movably and limit-connected. When the telescopic support rod 1 is stretched, the situation of disconnection is solved.

[0029] In one embodiment, the four groups of the bosses 6 are respectively arranged below the first sleeve rod 11, the second sleeve rod 12, the third sleeve rod 13 and the fourth sleeve rod 14. The inner convex ring 5 is movably and limit-connected with the boss 6, and when the telescopic support rod 1 is stretched, the disconnection situation is solved.

[0030] In one embodiment, the card holes 7 are respectively arranged at the front and rear parts of the upper end of the first sleeve rod 11, and on the bosses 6 on the lower sides of the second sleeve rod 12, the third sleeve rod 13 and the fourth sleeve rod 14. When the second sleeve rod 12 is contracted to the end of the third sleeve rod 13, the one-way card 8 on the second sleeve rod 12 will be stuck into the card hole 7 of the third sleeve rod 13.

[0031] In one embodiment, the one-way card 8 is arranged on the bosses 6 on the lower sides of the first sleeve rod 11, the second sleeve rod 12 and the third sleeve rod 13. When the first sleeve rod 11 is contracted to the end of the second sleeve rod 12, the one-way card 8 on the first sleeve rod 11 will be clamped into the card hole 7 of the second sleeve rod 12.

[0032] Working principle: On one side of the sleeve rod of the telescopic support rod 1, there is a one-way card 8, and on the other side, there is a card hole 7. The inner convex ring 5 is movably and limit-connected with the boss 6. When the telescopic support rod 1 is stretched, disconnection is prevented, so as to achieve a limiting effect, restricting the first sleeve rod 11 from entering the third sleeve rod 13 and the second sleeve rod 12 from entering the fourth sleeve rod 14. When the first sleeve rod 11 is contracted to the end of the second sleeve rod 12, the one-way card 8 on the first sleeve rod 11 will be clamped into the card hole 7 of the second sleeve rod 12. When the second sleeve rod 12 is contracted to the end of the third sleeve rod 13, the one-way card 8 on the second sleeve rod 12 will be stuck into the card hole 7 of the third sleeve rod 13, thus solving the problem of cross-bar contraction.
