Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a novel backrest chair which is easy to assemble. Background Art

[0002] As a daily necessity, backrest chairs are often used in daily life. In fixed places such as homes, dormitories or offices, people usually use backrest chairs with fixed structures. Existing backrest chairs are either too simple in structure, which affects the overall strength of the backrest chair, or too complex in design structure, which cannot provide sufficient overall strength and cannot be well applied to home use environments.

[0003] Common outdoor chairs in the prior art include foldable and fixed types. The foldable chair is flexible and convenient to use, and is easy to transport and store, but its main disadvantages are instability, easy damage, too simple structure, unsightly appearance, and uncomfortable to sit on. The existing fixed chair is not easy to assemble and disassemble, and is troublesome to transport, carry, and store, and is expensive. Summary of the invention

[0004] In view of this, the purpose of the utility model is to provide a new type of armchair that is easy to assemble and disassemble and easy to transport.

[0005] The utility model is realized by the following method: a new type of chair with backrest that is easy to assemble, comprising a support frame, the cross-section of the support frame is H-shaped, a first slot is provided in the middle of the upper surface of the transverse plate of the support frame, a T-shaped support plate is mounted on the support frame, a second slot matching the first slot is provided on the lower surface of the transverse plate of the T-shaped support plate, a seat plate is mounted on the T-shaped support plate, a limiting slot matching the transverse plate of the T-shaped support plate is provided on the lower surface of the seat plate, and an arc-shaped backrest plate is mounted on the support frame and the T-shaped support plate.

[0006] Furthermore, the support frame and the T-shaped support plate cooperate to form a triangular support.

[0007] Furthermore, threaded holes are provided on the upper surfaces of the support frame and the T-shaped support plate, and the arc-shaped backrest plate is fixed to the support frame and the T-shaped support plate by screws.

[0008] The beneficial effects of the utility model are that a support frame, a T-shaped support plate, a seat plate and a curved backrest plate are added to the device, which is convenient for realizing rapid assembly and disassembly of the whole. The utility model is convenient and fast, has a flexible and simple structure, is easy to assemble, saves time and effort in assembly, improves production efficiency, and has certain promotion and application value.

[0012] The utility model is further described below in conjunction with the accompanying drawings.

[0013] See also Figures 1 to 3 As shown, the utility model provides an embodiment: a new type of backrest chair that is easy to assemble, comprising a support frame 1, the cross section of the support frame 1 is H-shaped, a first slot 2 is provided in the middle of the upper surface of the horizontal plate of the support frame 1, a T-shaped support plate 3 is mounted on the support frame 1, a second slot 4 matching the first slot 2 is provided on the lower surface of the horizontal plate of the T-shaped support plate 3, a seat plate 5 is mounted on the T-shaped support plate 3, a limiting slot 6 matching the horizontal plate of the T-shaped support plate 3 is provided on the lower surface of the seat plate 5, and an arc-shaped backrest plate 7 is mounted on the support frame 1 and the T-shaped support plate 3. Through the matching of the first slot 2 and the second slot 4, the connection between the support frame 1 and the T-shaped support plate 3 can be realized, and then the limiting slot 6 is inserted from the front end into the horizontal plate of the T-shaped support plate 3 and pushed backward, so as to realize the installation of the seat plate 5, and finally the arc-shaped backrest plate 7 is installed and fixed on the triangular support formed by the matching of the support frame 1 and the T-shaped support plate 3 to realize the installation of the whole backrest chair.

[0014] Please continue reading Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the support frame 1 and the T-shaped support plate 3 cooperate to form a triangular support, thereby increasing the stability and strength of the seat itself.

[0015] Please continue reading Figure 1 As shown, in one embodiment of the utility model, the upper surfaces of the support frame 1 and the T-shaped support plate 3 are both provided with threaded holes 8, and the arc-shaped backrest plate 7 is fixed to the support frame 1 and the T-shaped support plate 3 by screws. Through the action of the screws, the arc-shaped backrest plate 7 can be connected and fixed to the support frame 1 and the T-shaped support plate 3 to form a backrest effect.

[0016] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
