Example Embodiment

[0039] Example one

[0040] Such as figure 1 with figure 2 As shown, the combined disassembly and assembly chair leg includes a middle disc seat 1, and five single-leg connecting seats 2 that are connected in the circumferential direction of the middle disc seat 1 and are evenly distributed on the circumference. Further, the middle seat in this embodiment The disk base 1 and the single-leg connecting base 2 are integrally formed by injection molding. For example, PA material and so on.

[0041] Secondly, such as Figure 4 with Figure 5 As shown, a number of weight-reducing blind holes 10 are evenly distributed on the lower surface of the middle plate seat 1, and at least one weight-reducing blind hole 10 is provided on the lower surface of each single-leg connecting seat 2 close to the middle plate seat 1. 孔二27. Weight-reducing blind holes can save materials and reduce manufacturing costs.

[0042] Such as image 3 with Image 6 As shown, the upper surface of each single-leg conn...

Example Embodiment

[0066] Example two

[0067] The working principle and structure of this embodiment are basically the same as those of the first embodiment. The different structure is that the outer axial concave-convex locking structure includes a locking hole provided on the lower surface of the single-leg connecting seat 2 away from the end of the middle disk seat 1. 37. An upwardly protruding lower locking protrusion 29 is provided at the inner end of the lower side of the flip assembly foot 3, and the lower locking protrusion 29 is inserted into the lock after the flip assembly foot 3 is turned upside down. In the stop hole 37, an L-shaped buckling surface 290 is provided on the side of the lower locking protrusion 29 that is close to the middle disk seat 1 in the circumferential direction, and the L-shaped buckling surface 290 is buckled when the flip assembly foot 3 is turned upside down. It is fitted on the hole wall of the locking hole 37 on the side close to the middle disc seat 1, the ...

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. [0004] Common chair legs have integral injection molding, and there are also detachable connections between the center plate seat and single leg. In order to facilitate transportation and reduce transportation costs, at present, more chair legs use the center plate seat and single leg detachable. way, because the two components can be packaged and shipped separately, further improving space utilization. [0005] Although the existing detachable chair foot has the above advantages, the above-mentioned chair foot has the following disadvant...
