[0002] Chairs are indispensable items in life and are widely present in our daily environment.

[0003] Most chairs on the market currently use screws to connect various parts, or directly fix the connections. This method not only makes the chair assembly and disassembly process cumbersome, but also affects the overall appearance of the chair, especially when the screws are rusted, which reduces the aesthetics of the chair; in addition, the existing chairs are also injection-molded in one piece, which makes it impossible to disassemble during transportation, thereby occupying a large space and increasing transportation costs; at the same time, the one-piece injection-molded chair is easily damaged during transportation, which increases transportation losses.

[0004] For example, Chinese patent CN201320824755.4 discloses a chair in which various components are fixed together by screws, which makes disassembly and assembly complicated and affects the overall appearance.

[0052] Both sides of the rear end surface of the seat plate 2 are recessed forward to form a four-way card slot 22, the width of which matches the thickness of the side plate 1, and both sides of the front end surface of the seat plate 2 are recessed backward to form a three-way card slot 21 that matches the thickness of the side plate 1, and a protrusion 24 extends forward from the front end surface of the seat plate 2 between the two three-way card slots 21;

[0053] The left and right sides of the lower half of the backrest 3 are both inwardly recessed with an avoidance groove 33, the upper side wall of the avoidance groove 33 is recessed upward to form a card groove 5 31, and the lower side wall of the avoidance groove 33 is protruding to form a plug-in portion 1 32;

[0054] A support portion 42 protrudes upwards in the middle of the front cross beam 1 4, and a clamping groove 7 41 is recessed upwards on the lower sides of the left and right ends of the front cross beam 1 4;

[0055] The left and right ends of the rear cross beam 5 are both provided with a plug-in portion 51, and the plug-in portion 51 is provided with a slot 9 52;

[0056] After assembly, the side end of the seat plate 2 is placed in the opening 11, the slot four 22 is engaged with the slot six 111, the slot three 21 is engaged with the bottom of the front side wall of the opening 11, the rear side of the side plate 1 is placed in the avoidance groove 33, and the slot five 31 is engaged with the slot one 12, the plug-in portion 1 32 is embedded in the slot two 13, the support portion 42 abuts against the lower end of the protrusion 24, the slot seven 41 is engaged with the lower side wall of the slot eight 15, the plug-in portion two 51 is inserted into the slot eleven 16, and the slot nine 52 is engaged with the slot eleven 16 and is tightly connected.

[0057] First, insert the side end of the seat plate 2 into the opening 11, and then make the fourth slot 22 and the sixth slot 111 fit together and tightly connected, and then rotate the front end of the seat plate 2 with the sixth slot 111 as the center of the circle, so that the third slot 21 and the bottom of the front side wall of the opening 11 are fit together and tightly connected, and the inner walls of the fourth slot 22 and the third slot 21 on the outside are both in contact with the side end of the side plate 1, thereby improving the force-bearing capacity of the middle part of the seat plate 2.

[0058] When the side panel 1 and the backrest 3 are installed, the upper half of the side panel 1 can be placed in the avoidance groove 33, and the upper side wall of the avoidance groove 33 is placed on the upper end surface of the side panel 1, so that the locking groove 5 31 and the locking groove 1 12 are embedded and connected.

[0059] The end of the front cross beam 4 is first inserted into the slot 8 15, and then the front cross beam 4 moves downward so that the slot 7 41 is embedded and tightly connected with the lower side wall of the slot 8 15. When the seat plate 2 is installed on the side plate 1, the support portion 42 abuts against the lower end of the protrusion 24 to support the front end of the seat plate 2 to prevent the seat plate 2 from being bent and deformed due to excessive force.

[0060] The side panel 1 located at the rear side wall of the opening 11 is tilted. When the backrest 3 is installed on the side panel 1, the side wall of the backrest 3 is flush with the rear side of the upper half of the side panel 1, so that the backrest 3 is tilted after installation, which is convenient for fitting with the back of a person and improves the comfort of use.
