Embodiment 1

[0012] As shown in Figure 1, a five-star base of the present invention is composed of a base and casters 3. The base is composed of a central plate 1 and five extension arms 2 that radiate outward from the central plate 1, wherein any one Each of the extension arms 2 is provided with a groove 4 along its length, and any one of the grooves 4 is fitted with a strut 5, and any one of the struts 5 is fitted along its length. direction is provided with more than two through holes, and the bottom surface of any groove 4 is provided with more than two screw holes 7 along its length direction, and at least one of the screw holes 7 is provided with a bolt 6, so The bolt 6 passes through at least one of the through holes, and the caster 3 is arranged on the outer end of the strut 5 .

[0013] Further, the extension arm 2 is composed of a channel-shaped member with an H-shaped cross section.

[0014] Further, the caster 3 is provided with a locking device.

[0015] Further, the caster ...

Abstract

The invention discloses a star base, which consists of a base and a castor. The base is formed by connecting a central disk and five extension arms radiated from the central disk; any one of the extension arms is provided with a groove along the length direction thereof; a support post is embedded in any one of grooves; any one of support posts is provided with more than two through holes along the length direction thereof; the bottom surface of any one of the grooves is provided with more than two screw holes along the length direction thereof, and a bolt is arranged in at least one screw hole and at least passes through one through hole; the castor is arranged at the outer end of the support post, and is provided with a locking device; the relative positions of the extension arms and the support post can be adjusted so as to change the radius of the star base and reduce cost; and the locking mechanism is arranged in the castor so as to avoid the problem that a vacant seat slides freely.

Description

Technical field: [0001] The present invention relates to articles for human life, in particular to furniture, in particular to a support foot of a seat, in particular to a five-star foot. Background technique: [0002] Seats (such as computer chairs, executive chairs) often use five-star feet. In the prior art, the five-star base is integrally formed and has a fixed radius. Therefore, a set of molds must be equipped for each production of a five-star base. This production method is costly for the manufacturer, and it is difficult to form specialization. Mass production. In addition, the five-star casters do not contain a brake device, and the empty seat will slide away when touched, causing inconvenience for users to sit again. Invention content: [0003] The object of the present invention is to provide a five-star base, which solves the technical problems in the prior art that the radius of the five-star base of a seat cannot be adjusted, and the casters have no brakin...
