Description

Technical Field

[0001] The utility model belongs to the technical field of anti-myopia hunchback brackets, and in particular relates to an anti-myopia hunchback bracket. Background Art

[0002] Primary school is a learning process that everyone must go through. Primary school students are a very important period for the induction of myopia and hunchback. There are mostly three reasons for myopia in primary school students. The first is the light problem. Too strong or too weak light will cause the eyes to be in a state of discomfort for a long time. The second is fatigue caused by long-term use of the eyes. The third is the bulge of the lens caused by long-term close viewing. In addition, incorrect sitting posture is also one of the causes of myopia. Incorrect sitting posture will also cause primary school students to have hunchbacks. When using the eyes at close range, the body should remain still, sit upright, and the book should be placed about 30cm away from the eyes. Bad habits such as riding in a car, lying in bed, or reading with your head tilted at a desk will increase the burden of eye adjustment and increase the pressure of the extraocular muscles on the eyeball. Especially for primary and secondary school students, the eyeball is in the development stage. Long-term bad eye posture can easily cause abnormal development of the eyeball and lead to the formation of myopia. When writing, it is best to shine the light from the left front to the book to avoid the light being blocked by the right hand when writing. Because primary school students have poor self-regulation awareness and ability, incorrect sitting posture usually leads to the dual problems of myopia and hunchback. For this purpose, a sitting posture correction frame is used to correct the sitting posture of primary school students when they are learning to write, so that the distance between them and the desk is appropriate, thereby correcting their sitting posture, correcting their vision and hunchback problems. When using the existing anti-myopia hunchback bracket, in order to meet the needs of primary school students of different heights, the anti-myopia hunchback bracket can adjust the height of the correction frame, but the adjustment method is to fix and adjust by screwing screws, which makes the operation more troublesome and the children cannot easily adjust it by themselves. For this reason, we propose an anti-myopia hunchback bracket. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figures 1 to 3 The utility model provides a technical solution: an anti-myopia hunchback bracket, comprising a main body 1, a limiting frame 2 is arranged at the top of the main body 1, a mounting seat 3 is fixed to the bottom end of the main body 1, a height adjustment mechanism is arranged between the limiting frame 2 and the main body 1, a clamping protection mechanism is arranged inside the mounting seat 3, and the height adjustment mechanism comprises: a connecting guide component, which is arranged at the connection between the limiting frame 2 and the main body 1; a limiting component, which is arranged on the inner side of the connecting guide component; and a pressing component, which is arranged on both sides of the connecting guide component and connected with the limiting component.

[0018] In this embodiment, preferably, the connecting guide assembly includes a connecting groove 100 opened at the top of the main body 1 and a connecting rod 101 fixed at the bottom end of the limit frame 2. The connecting rod 101 is slidably connected to the connecting groove 100, so that the limit frame 2 and the main body 1 can be adjusted and connected.

[0019] In this embodiment, preferably, a guide groove 200 and a guide block 201 fixed inside the connecting groove 100 are formed through the surface of the connecting rod 101, and the guide block 201 is engaged with the guide groove 200 to limit the movement of the connecting rod 101.

[0020] In this embodiment, preferably, the limit assembly includes limit grooves 300 symmetrically and equidistantly provided on both sides of the inner wall of the connecting groove 100 and a through groove 301 penetrating through the side of the bottom end of the connecting rod 101, and the inside of the through groove 301 is symmetrically provided with a limit block 302. The limit block 302 is engaged with the limit groove 300, so that the position of the connecting rod 101 after the height is adjusted inside the connecting groove 100 can be positioned, and the inside of the through groove 301 is provided with a telescopic spring 303 connected with the limit block 302, which can drive the limit block 302 to reset and bounce up.

[0021] In this embodiment, preferably, the pressing assembly includes a built-in groove 400 symmetrically opened at the top of the inner wall of the through groove 301 and a groove 401 penetrated and opened on both sides of the connecting rod 101 and connected to the built-in groove 400. A push block 402 passing through the inside of the groove 401 is arranged on the side of the connecting rod 101. A transmission rod 403 fixedly connected to the limit block 302 is arranged at the end of the push block 402 and relative to the inside of the built-in groove 400, which can drive the limit block 302 to withdraw from the inside of the limit groove 300 when the push block 402 is pressed.

[0022] In this embodiment, preferably, the clamping protection mechanism includes a rubber pad 500 fixed to the top of the inner part of the mounting seat 3, which can protect the surface of the table top during clamping and fixing to avoid clamping marks.

[0023] The working principle and use process of the utility model: when the height of the limit frame 2 needs to be raised, the limit frame 2 only needs to be pulled to drive the connecting rod 101 to slide inside the connecting groove 100, and the beveled part at the end of the limit block 302 is squeezed with the limit groove 300, so that the limit block 302 can squeeze the telescopic spring 303 to deform and shrink into the inside of the through groove 301, and drive the transmission rod 403 to move inside the built-in groove 400, and drive the push block 402 to slide inside the groove 401, so that the connecting rod 101 can be raised inside the connecting groove 100, and drive the guide groove 200 to slide on the surface of the guide block 201 to play a moving guiding role, so as to increase the height of the limit frame 2 on the main body 1. When the limit frame 2 is adjusted to a suitable height, the through groove 301 and the limit of the corresponding height are The positioning groove 300 is aligned, so that the limit block 302 is popped out from the inside of the through groove 301 and stuck into the inside of the limit groove 300 under the action of the telescopic spring 303, so that the position of the connecting rod 101 inside the connecting groove 100 can be positioned to complete the adjustment work. When it is necessary to lower the height of the limit frame 2, it is only necessary to press the push blocks 402 on both sides of the top of the connecting rod 101 to retract it into the inside of the groove 401, and drive the transmission rod 403 to move inside the built-in groove 400, and at the same time drive the limit block 302 to withdraw from the inside of the limit groove 300 to squeeze the telescopic spring 303 into the inside of the through groove 301, so that the positioning of the connecting rod 101 can be released, and then the limit frame 2 can be pressed to lower the height. When it is necessary to clamp the mounting seat 3 and the table top, the rubber pad 500 can be used to protect the surface of the table top to avoid clamping marks.
