The chair has the function of correcting the behavior of students. However, this chair does not allow for a quantitative adjustment of the distance of the chest support from the back of the chair.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a seat convenient to correct position of sitting.

The utility model discloses a following technical scheme can realize:

the utility model provides a seat convenient to correct position of sitting, includes seat, U-shaped correction subassembly and length measurement subassembly, the bottom of seat is equipped with the chair leg, be equipped with the back on the seat, the top of back is equipped with the pivot, the open end and the pivot of U-shaped correction subassembly are rotated and are connected, length measurement subassembly is established on the U-shaped correction subassembly.

The U-shaped straightening assembly comprises a straightening rod and two connecting rods arranged on the straightening rod side by side.

The connecting rod is a telescopic rod with adjustable length.

And a magnet is arranged at one end of the connecting rod, which is far away from the straightening rod, and the magnet is positioned at the upper side of the connecting rod.

The surface of the correcting rod is coated with an elastic pad.

The length measuring component is a tape measure.

The tape is arranged at one end, far away from the correcting rod, of the connecting rod, and a graduated scale in the tape is connected with the correcting rod.

And the top of the backrest is provided with a limiting plate and a cushion block.

The beneficial effects of the utility model reside in that: the length of the connecting rod can be adjusted by referring to the scale on the tape, so that the correcting rod is positioned at a proper position in front of the chest, and can be touched when the body excessively leans forward, thereby achieving the purpose of reminding a user of sitting upright through the correcting rod. When not needing to rectify the position of sitting, the seat also can regard as ordinary chair to use, convenient and practical, and magnet adsorbs on the limiting plate, and the U-shaped correction subassembly is difficult for empting in the use.

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view of a portion of FIG. 1 at A;

fig. 3 is a schematic structural view of the U-shaped correcting component of the present invention when being perpendicular to the seat.

In the figure: 1-chair legs, 2-chair seat, 3-backrest, 4-rotating shaft, 5-connecting rod, 6-correcting rod, 7-magnet, 8-limiting plate, 9-length measuring component and 10-cushion block.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in figures 1 to 3, a seat convenient to correct position of sitting, correct subassembly and length measurement subassembly 9 including seat 2, U-shaped, four chair legs 1 are installed side by side to the bottom of seat 2, install back 3 on the seat 2, the top of back 3 is equipped with two pivots 4, the open end and the pivot 4 rotation of subassembly are corrected to the U-shaped are connected, length measurement subassembly 9 is installed on the subassembly is corrected to the U-shaped.

The U-shaped straightening assembly comprises a straightening rod 6 and two connecting rods 5 which are arranged on the straightening rod 6 side by side.

The connecting rod 5 is a telescopic rod with adjustable length. So that the length of the U-shaped correcting component can be adjusted according to the requirement. The telescopic rod is the prior art and is not described herein again.

And a magnet 7 is arranged at one end of the connecting rod 5 far away from the straightening rod 6, and the magnet 7 is positioned at the upper side of the connecting rod 5. When the U-shaped correction component is perpendicular to the seat surface 2, the magnet 7 is adsorbed on the limiting plate 8, and the U-shaped correction component is prevented from toppling.

The surface of the correcting rod 6 is coated with an elastic pad. When the correction rod is used, the elastic cushion is a spongy cushion and the like, the comfort level of the correction rod 6 is improved through the elastic cushion, and chest discomfort caused by forward leaning of a body on the correction rod 6 is avoided.

The length measuring component is a tape measure.

The tape is arranged at one end of the connecting rod 5 far away from the correcting rod 6, and a graduated scale in the tape is connected with the correcting rod 6. The length of the connecting rod 5 can be adjusted by referring to the scale on the tape.

And a limiting plate 8 and a cushion block 10 are mounted at the top of the backrest 3. The U-shaped correcting component is limited through the limiting plate 8 and the cushion block 10, so that the U-shaped correcting component can only rotate within the range of 0-90 degrees relative to the chair surface 2. The limiting plate 8 is an iron plate or the like, so that the magnet 7 can be adsorbed on the limiting plate 8.

A seat convenient to correct position of sitting, its use as follows:

lifting the correcting rod 6 to enable the connecting rod 5 to extend to a proper position, then sitting on a seat, rotating the U-shaped correcting component to enable the correcting rod 6 to go around the top of the head and continue to rotate to the front of the human body, referring to the scale on the tape, adjusting the length of the connecting rod 5 to enable the correcting rod 6 to be located at a proper position in front of the chest (the correcting rod is recommended to be adjusted to be 3cm away from the chest), and when the body excessively leans forward, the correcting rod 6 can be touched, so that the aim of reminding a user of sitting upright through the correcting rod 6 is fulfilled.

When not needing to rectify the position of sitting, the utility model provides a seat also can regard as ordinary chair to use, with U-shaped correction subassembly rotate with 2 vertically positions of seat, pushes down levelling rod 6, makes connecting rod 5 shrink to the shortest position, and magnet 7 adsorbs on limiting plate 8, and U-shaped correction subassembly is difficult for empting in the use.

In conclusion, the length of the connecting rod 5 can be adjusted by referring to the scale on the tape, so that the correcting rod 6 is positioned at a proper position in front of the chest, and the body can touch the correcting rod 6 when excessively leaning forward, thereby achieving the purpose of reminding the user of sitting upright through the correcting rod 6. When not needing to rectify the position of sitting, the seat also can regard as ordinary chair to use, convenient and practical, and magnet 7 adsorbs on limiting plate 8, and the U-shaped correction subassembly is difficult for empting in the use.
