[0005] 2. The armrest assembly is fixedly arranged integrally. When a user with a large body size sits on the seat, the positions of the left and right armrests will squeeze against the body part, and the user will feel uncomfortable.

[0006] 3. When not in use, it occupies a large space. Summary of the Utility Model

[0007] The purpose of the utility model is to solve the above problems of the existing technology, and provide a novel foldable armrest structure with a simple structure, flexible use and small occupied space.

A left limiting convex column extends outside the plastic spacer sleeve on the side; a plastic spacer sleeve is sleeved outside the end of the right armrest assembly, and a right limiting convex column extends outside the plastic spacer sleeve on the side; the reduced tube is inserted into the end of the right armrest assembly so that the left and right armrest assemblies are relatively rotationally connected and then placed into the lower accommodating groove. The left limiting convex column is placed into the left limiting groove to limit its rotation angle, and the right limiting convex column is placed into the right limiting groove to limit its rotation angle. The upper buckle seat is buckled onto the lower buckle seat, and the left and right armrest assemblies are limited to rotate relatively within the cylindrical accommodating cavity formed by the buckling of the upper and lower buckle seats after being connected.

[0010] Further, the side of the plastic spacer sleeve is grooved, and is expanded and sleeved outside the ends of the left and right armrests at the grooved place, and a relief groove is provided at the left and right limiting convex columns.

[0011] Further, the middle of the lower buckle seat is a semi-circular lower accommodating groove, and the semi-circular lower accommodating groove extends to both sides to form two lower fixing plates, and through holes are respectively formed on the two lower fixing plates; the middle of the upper buckle seat is a semi-circular upper accommodating groove, and the semi-circular upper accommodating groove extends to both sides to form two upper fixing plates, and through holes are respectively formed on the two upper fixing plates; the upper and lower buckle seats are fastened and fixed by a bolt assembly passing through the through holes.

[0012] Further, the bolt assembly includes a bolt and a flat washer, and the bolt assembly is tightened in the through hole to fasten and fix the upper and lower buckle seats.

[0013] After adopting the above scheme, compared with the prior art, the left and right armrest assemblies of the present utility model are separately arranged, can rotate relatively, and can be rotated and folded respectively around the limit channel, ensuring that the user is not easily hit by the armrest when getting on or off the seat cushion, and is more convenient to use. It also meets the requirement that when a user with a large build sits on the seat cushion, the position of the armrest will not squeeze the body part to ensure comfort. And when not in use, it can be folded, occupying less space. BRIEF DESCRIPTION OF THE DRAWINGS
