Combined detachable chair leg

Abstract

A combined detachable chair leg comprises a middle disc seat and five single-foot connecting seats, and the five single-foot connecting seats are connected to the circumference of the middle disc seatand are uniformly distributed in the circumferential direction; the upper surface of each single-foot connecting seat is provided with an avoiding inclined plane and a matching inclined plane I whichare sequentially connected from outside to inside; the combined detachable chair leg also comprises five overturning assembly single feet in one-to-one correspondence with the single-foot connectingseats; matched inclined planes II are arranged on the inner walls of the upper sides of the ends, close to the single-foot connecting seats, of the overturning assembly single feet; an inner axial locking structure is arranged between the end, close to the middle disc seat, of each single-foot connecting seat and the end, close to the single-foot connecting seat, of the corresponding overturning assembly single foot, and when the overturning assembly single feet overturn upwards to enable the matching inclined planes I to be matched with the matching inclined planes II, the overturning assembly single feet can be limited from moving towards the side of the middle disc seat excessively in the axial direction of the single-foot connecting seats by inner axial locking structure, and an outeraxial concave-convex locking structure for preventing the corresponding overturning assembly single foot from being separated outwards along the axial direction of the corresponding single-foot connecting seat is arranged between one end, far away from the middle disc seat, of the lower surface of each single foot connecting seat and the lower side edge of the corresponding overturning assembly single foot.

Description

technical field [0001] The invention belongs to the technical field of swivel chair accessories, in particular to a combined detachable chair foot. Background technique [0002] The chair foot is an important accessory in the chair. [0003] In the field of swivel chairs, the pentagonal chair foot is a conventional structure, which includes a center plate base and five single feet connected to the circumference of the center plate base.
