Abstract
Description
Technical Field
[0001] The utility model relates to the field of desks with a sitting posture correction function, in particular to a desk with a sitting posture correction function. Background Art
[0002] It is a common occurrence for every child of school age to read and write on the table. If they do not have a good sitting posture when working at a desk, they may suffer from myopia, hunchback and other physical deterioration. Especially for minors who are in the process of physical development, long-term improper sitting posture will have lifelong impact on the body.
[0003] Good sitting posture should be developed from an early age. In order to correct children's sitting posture when writing at a desk, many desks and chairs with sitting posture correction function have been launched on the market. Among them, the most common posture correction desk in shopping malls is equipped with a baffle on the table top to block the child's chest. When the child wants to lean forward and slowly crawl to the table top, the child's body will be reminded and blocked, thereby preventing the child from bending over and hunching his back during the writing process, which will cause bad sitting posture to affect the body.
[0004] Although it has a corrective function, the correct sitting posture and the formation of good sitting habits are completed based on the suitability of the child's seat and the limit correction end. A single baffle is effective but not comprehensive. For example, when a child is doing homework, he gets tired and his chin rests on the limit block, or the position and size of the seat are not suitable for the child's body shape, the baffle cannot play a role and becomes an obstacle instead. Alternatively, although the baffle is against the child's chest, the lower back will slowly bend over a long period of time due to habit, which cannot meet the basic needs of correcting the child's sitting posture. Therefore, a desk with a corrective sitting posture function is needed. Utility Model Content

[0040] Embodiment 5
[0041] Combined with Figure 1 , 2 6. A plurality of connecting rods 25 are connected to both sides of the base 1. The connecting rod 25 is connected to a support block 26 with a groove at the bottom at one end away from the base 1. A spring 27 is downwardly connected inside the support block 26. When a child sits in the desk device, the gravity of the spring 27 increases and the base 1 is fixed to the ground. When the child leaves, the spring 27 is lifted to expose the wheels 29 for easy movement. The bottom end of the spring 27 is connected to a support frame 28. The bottom of the support frame 28 is rotatably connected to the wheels 29 for easy movement on the ground when the desk device is not in use.
[0042] When the present invention is implemented in practice, when using the desk device, parents first adjust the height of the pedal 16 through the various fixing threads and bolts 14 under the seat 8 according to the child's own characteristics and needs, so that the distance between the pedal 16 and the seat 8 is suitable for the placement distance of the child's legs, which also plays an auxiliary role in correcting the child's sitting posture. Then, the handle 24 on the table board 2 is manually driven to adjust the limit block 23 used to limit the excessive forward leaning of the child's upper body when working at the desk to a suitable distance from the edge of the table board 2. For example, some schools require students in lower grades to keep a fist length between their chest and the table when writing at the desk. After the above two position adjustments are completed, the child can sit down, and through the corresponding control end, the motor 5 is moved to drive the threaded column in the base 1 to rotate, thereby adjusting the distance between the table board 2 and the seat 8 until the child can write in a correct and comfortable posture. If the seat 8 is too high Or if the child is too short, it can also be adjusted by the No. 1 electric telescopic rod 7 under the seat 8, and the height position of the limit block 23 supported on the child's chest makes the child uncomfortable, and it can also be fine-tuned by the No. 2 electric telescopic rod 18 in the support 17. The above-mentioned adjustment methods are all used to cooperate with the child to be able to work at the desk in a correct and comfortable posture, so that the child can be more effective and comfortable when the sitting posture is corrected, and the applicable age and body shape range of children is also relatively wide. In addition, the desk device is provided with wheels 29 to facilitate the movement of the device on the ground. When the child sits on the seat 8, the weight of the base 1 and the part above it increases, compressing the springs 27 in each support block 26, so that the wheels 29 retract into the support block 26, and the bottom end of the base 1 fits with the ground. Through friction, the desk device is fixed to the ground. When the child leaves, due to the reduction in weight and the effect of the spring 27, the wheels 29 are extended, so that it can be moved again.
[0043] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
