Detailed Description

The application is described in further detail below with reference to fig. 1-2.

The embodiment of the application discloses a pull rope dining chair. Referring to fig. 1, the pull-cord dining chair includes a support chassis 1 and a backrest bracket 2, the backrest bracket 2 being detachably mounted on the support chassis 1. When the support underframe 1 or the backrest bracket 2 is damaged, the backrest bracket 2 can be directly detached from the support underframe 1, and then the support underframe 1 or the backrest bracket 2 is replaced, so that the cost and the maintenance cost of the dining chair in the use process are reduced.

Referring to fig. 1 and 2, the support chassis 1 includes a bearing frame 11 and chair legs 12, the chair legs 12 are mounted to an outer sidewall of the bearing frame 11 for supporting the bearing frame 11, and the bearing frame 11 supports a user, i.e., the user sits on the bearing frame 11. The chair pad is placed on top of the support frame 11, thereby improving the comfort of the chair.

The backrest bracket 2 is arranged at the top of the supporting frame 11 through bolts, and countersunk holes for embedding the bolt heads of the bolts are formed in the backrest bracket 2. In addition, a rope is wound around the back rest bracket 2 for improving the aesthetic appearance (not shown in the drawings).

Referring to fig. 1 and 2, wherein one side of the back rest bracket 2 in the horizontal direction is provided with an opening through which a user will sit on the support frame 11 and rest the back on the back rest bracket 2. The opening is provided with a front end of the supporting frame 11 and the backrest bracket 2, and the side opposite to the opening is provided with a rear end. The height from the top of the front end of the backrest bracket 2 to the ground is lower than the height from the top of the rear end of the backrest bracket 2 to the ground, and the backrest bracket is arranged in an inclined state. And further, the arms of the user can be placed on the backrest bracket 2 when the back of the human body can be well supported.

The height from the front end of the supporting frame 11 to the ground is higher than the height from the rear end of the supporting frame 11 to the ground, so that the supporting frame 11 is in an inclined state, and the gravity center of a human body can deviate to the rear part after sitting on the supporting frame 11, so that the human body can rest on the backrest bracket 2 more comfortably under the action of inertia. In addition, the inclined arrangement of the supporting frame 11 also makes people not easy to slide off the dining chair.

Referring to fig. 1 and 2, the chair includes front support legs 13 and rear support legs 14, the front support legs 13 are symmetrically provided with two front support legs 13 at the front end of the bearing frame 11 and the bearing frame 11 is positioned between the two front support legs 13, the rear support legs 14 are also symmetrically provided with two rear support legs 14 at the rear end of the bearing frame 11 and the bearing frame 11 is positioned between the two rear support legs 14. The back end of the bearing frame 11 is hinged to the two back end supporting legs 14, so that the inclination angle of the front end of the bearing frame 11 can be adjusted to meet the requirements of different people.

Wherein, the top of front end supporting leg 13 and the top of rear end supporting leg 14 are located the top of bearing frame 11, and then make front end supporting leg 13 and rear end supporting leg 14 be located the part of bearing frame 11 top and can carry out a stop spacing to back support 2. In addition, the bottoms of the front end support leg 13 and the rear end support leg 14 are glued with anti-slip friction pads 15 by glue.

Referring to fig. 1 and 2, the bottoms of the rear support legs 14 are gradually inclined away from the direction of the front support legs 13, and compared with the vertical arrangement of the rear support legs 14, the inclined arrangement of the rear support legs 14 can improve the stability of supporting the bearing frame 11. A connecting rod 16 is welded between the rear end support leg 14 and the front end support leg 13, and similarly, a connecting rod 16 is welded between the two rear end support legs 14, so that the two front end support legs 13 and the two rear end support legs 14 form a stable chair leg 12 support.

A rotating shaft 141 is welded to one side of the back end of the bearing frame 11, which is close to the back end supporting leg 14, and a rotating hole for inserting the rotating shaft 141 is formed in one side of the back end supporting leg 14, which is close to the bearing frame 11.

Referring to fig. 1 and 2, an arc-shaped adjusting plate 17 is welded to a side of the front end of the bearing frame 11, which is close to the front end supporting leg 13, and a limit bolt 18, which is matched with the arc-shaped adjusting plate 17 to adjust the inclination angle of the bearing frame 11, is arranged on a side of the front end supporting leg 13, which is away from the bearing frame 11. The side of the arc-shaped adjusting plate 17, which is close to the front end supporting leg 13, is provided with a locking threaded hole 171 for inserting and connecting the limit bolt 18 in a threaded manner, the outer wall of the front end supporting leg 13 is provided with a penetrating hole, and the threaded end of the limit bolt 18 penetrates through the penetrating hole and then is inserted into the locking threaded hole 171, so that the rotation of the bearing frame 11 is limited.

Wherein the locking screw holes 171 are provided in plurality at intervals along the extending direction of the arc-shaped adjusting plate 17. When the angle of the supporting frame 11 needs to be adjusted, the limit bolts 18 are detached from the arc-shaped adjusting plate 17, then the front end of the supporting frame 11 is pulled to be adjusted, and the limit bolts 18 are inserted into the locking threaded holes 171 corresponding to the angle after the angle is adjusted to the desired angle.

The pull rope dining chair of the embodiment of the application has the implementation principle that after chair legs 12 are broken or bent, bolts for connecting a backrest bracket 2 and a support underframe 1 are loosened, the bolts are unscrewed, then the backrest bracket 2 is disassembled, and then one support underframe 1 is replaced. Simultaneously, the height from the front end of the supporting frame 11 to the ground is higher than the height from the rear end of the supporting frame 11 to the ground, so that the supporting frame 11 is in an inclined state, and the gravity center of a human body can deviate to the rear part after sitting on the supporting frame 11, so that the human body can rest on the backrest bracket 2 more comfortably under the action of inertia.

If a 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 detached from the arc-shaped adjusting plate 17, then the front end of the supporting frame 11 is pulled to adjust, and after the angle is adjusted to the desired angle, the limiting bolt 18 is inserted into the locking threaded hole 171 corresponding to the angle.

The above embodiments are not intended to limit the scope of the application, so that the equivalent changes of the structure, shape and principle of the application are covered by the scope of the application.
