[0021] The following is combined with Figure 1-2 This application is described in further detail.
[0022] The present application embodiment discloses a drawstring dining chair. Figure 1 The drawstring dining chair comprises a supporting frame 1 and a backrest bracket 2, and the backrest bracket 2 is detachably mounted on the supporting frame 1. When the supporting frame 1 or the backrest bracket 2 is damaged, the backrest bracket 2 can be directly removed from the supporting frame 1, and then the supporting frame 1 or the backrest bracket 2 can be replaced, thereby reducing the cost and maintenance cost of the dining chair during use.
[0023] Reference Figure 1 and Figure 2 The support frame 1 includes a support frame 11 and chair legs 12. The chair legs 12 are mounted on the outer side wall of the support frame 11 to support the support frame 11, and the support frame 11 is also used to support the user, that is, the user sits on the support frame 11. A chair cushion is placed on the top of the support frame 11, thereby improving the comfort of the chair.
[0024] The backrest bracket 2 is installed on the top of the supporting frame 11 by bolts, and a countersunk hole for the bolt head of the bolt to be embedded is provided on the backrest bracket 2. In addition, a rope is wound around the backrest bracket 2 to improve the aesthetics (not shown in the figure).
[0025] Reference Figure 1 and Figure 2 , wherein an opening is provided on one side of the backrest bracket 2 in the horizontal direction, through which the user will sit on the supporting frame 11 and lean his back against the backrest bracket 2. The opening is assumed to be the front end of the supporting frame 11 and the backrest bracket 2; the side opposite to the opening is the rear end. The height between the top of the front end of the backrest bracket 2 and the ground is lower than the height between the top of the rear end of the backrest bracket 2 and the ground, and is arranged in an inclined state. In addition, the user's arms can be placed on the backrest bracket 2 while being able to provide better support for the back of the human body.
[0026] The height from the front end of the support frame 11 to the ground is higher than the height from the rear end of the support frame 11 to the ground, so that the support frame 11 is in an inclined state. When people sit on the support frame 11, the center of gravity of the body can be biased to the rear, and then under the action of inertia, they can lean more comfortably on the backrest bracket 2. In addition, the inclined setting of the support frame 11 also makes it difficult for people to slide off the dining chair.
[0027] Reference Figure 1 and Figure 2The chair includes a front support leg 13 and a rear support leg 14. Two front support legs 13 are symmetrically arranged. The two front support legs 13 are located at the front end of the support frame 11, and the support frame 11 is located between the two front support legs 13. Two rear support legs 14 are also symmetrically arranged. The two rear support legs 14 are located at the rear end of the support frame 11, and the support frame 11 is located between the two rear support legs 14. The rear end of the support frame 11 is hinged to the two rear support legs 14, so that the inclination angle of the front end of the support frame 11 can be adjusted to meet the needs of different people.
[0028] The top of the front support leg 13 and the top of the rear support leg 14 are both located above the top of the support frame 11, so that the parts of the front support leg 13 and the rear support leg 14 located above the support frame 11 can block and limit the backrest bracket 2. In addition, the bottom of the front support leg 13 and the rear support leg 14 are both glued with anti-skid friction pads 15.
[0029] Reference Figure 1 and Figure 2 The bottom of the rear support leg 14 gradually tilts away from the front support leg 13. Compared with the vertical arrangement of the rear support leg 14, the tilted arrangement of the rear support leg 14 can improve the stability of the support frame 11. A connecting rod 16 is welded between the rear support leg 14 and the front support leg 13; similarly, a connecting rod 16 is also welded between the two rear support legs 14, so that the two front support legs 13 and the two rear support legs 14 form a stable chair leg 12 bracket.
[0030] A rotating shaft 141 is welded to one side of the rear end of the supporting frame 11 close to the rear end supporting leg 14 , and a rotating hole for inserting the rotating shaft 141 is opened on one side of the rear end supporting leg 14 close to the supporting frame 11 .
[0031] Reference Figure 1 and Figure 2 An arc-shaped adjustment plate 17 is welded to the side of the front end of the support frame 11 near the front end support leg 13, and a limit bolt 18 is provided on the side of the front end support leg 13 away from the support frame 11, which cooperates with the arc-shaped adjustment plate 17 to adjust the inclination angle of the support frame 11. A locking threaded hole 171 for the limit bolt 18 to be inserted and threaded is provided on the side of the arc-shaped adjustment plate 17 near the front end support leg 13, and a through hole is provided on the outer wall of the front end support leg 13, and the threaded end of the limit bolt 18 passes through the through hole and is inserted into the locking threaded hole 171, thereby limiting the rotation of the support frame 11.
[0032] There are a plurality of locking threaded holes 171 spaced apart along the extending direction of the arc-shaped adjustment plate 17. When the angle of the supporting frame 11 needs to be adjusted, the limiting bolt 18 is first removed from the arc-shaped adjustment plate 17, and then the front end of the supporting frame 11 is moved to adjust the angle, and after adjusting to the desired angle, the limiting bolt 18 is inserted into the locking threaded hole 171 corresponding to the angle.
[0033] The implementation principle of the drawstring dining chair of the embodiment of the present application is as follows: when the chair leg 12 is broken or bent, the bolts connecting the backrest bracket 2 and the support base 1 are loosened and unscrewed, and then the backrest bracket 2 is removed, and then a support base 1 is replaced. At the same time, the height from the front end of the support frame 11 to the ground is higher than the height from the rear end of the support frame 11 to the ground, so that the support frame 11 is in an inclined state, and the center of gravity of the body can be biased to the rear after people sit on the support frame 11, and then they can lean on the backrest bracket 2 more comfortably under the action of inertia.
[0034] If the person sitting on the dining chair wants to adjust the inclination angle of the supporting frame 11 to achieve the most comfortable sitting posture, the limiting bolt 18 is first removed from the arc-shaped adjustment plate 17, and then the front end of the supporting frame 11 is moved to adjust it. After adjusting to the desired angle, the limiting bolt 18 is inserted into the locking threaded hole 171 corresponding to the angle.
[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
