Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Referring to fig. 1-3, the present invention provides a technical solution: a frame structure of a chair comprises a seat plate 1, a backrest 2 and a pi-shaped handrail, wherein the lower part of the handrail is provided with a front supporting leg 3 and a rear supporting leg 3, the handrail comprises a first cross rod 4 which is arranged at the upper part of the supporting legs 3 and is used as a holding part and a second cross rod 5 which is arranged in the middle of the two supporting legs 3, two sides of the seat plate 1 are fixedly connected with the second cross rod 5 through a plurality of screw locking pieces, and the backrest 2 is fixedly connected with the first cross rod 4 through at least one screw locking piece; the bottom of the backrest 2 and the seat plate 1 are locked and connected in a detachable manner.
In the practical application process, the screw locking member can select to directly open holes on the corresponding first cross rod 4 and second cross rod 5 to lock the first cross rod 4 and second cross rod 5 on the seat plate 1 and the backrest 2 through screws by bolts, which is an achievable mode of the embodiment, but as the preferred mode of the embodiment, a first sleeve 6 is welded on the lower side of one end of the first cross rod 4 close to the backrest 2, two screw holes with internal screws are respectively arranged on two sides of the middle part of the backrest 2, the first cross rod 4 is locked on the middle part of the backrest 2 through screws penetrating through the first sleeve 6, a plurality of second sleeves 7 are welded on the lower surfaces of two sides of the seat plate 1, a plurality of screw holes with internal threads are arranged on the second cross rod 5, and the seat plate 1 is locked on the second cross rod 5 through screws penetrating through the second sleeves 7.
Welding the first 6 and second 7 sleeves at the ends of the first crossbar 4 and at the lower surface of the seat plate 1 has two advantages: 1. drilling is not needed, and only the corresponding sleeve needs to be welded, so that the processing difficulty is lowered; 2. the length of the screw is shortened, and the strength of the screw can be larger.
The installation process is as follows: the corresponding positions of the seat board 1, the backrest 2 and the two armrests are plugged with screws and then screwed, and finally the bottom of the backrest 2 and the seat board 1 are connected in a detachable mode in a locking mode.
