Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1, for the utility model discloses a high stability swivel chair metal five-star foot, including base 1, set up in base 1 five stabilizer blades 2 all around, set up in the triangular supports subassembly 3 of stabilizer blade 2 tip. By adopting the structure, the distribution range of the five-star foot can be enlarged while the arbitrary movement of the five-star foot is not influenced, so that the stability of the five-star foot is improved.

As shown in fig. 2, the triangular support assembly 3 includes a threaded hole 31 provided at an end of the leg 2, a screw 32 threaded into the threaded hole 31, a connecting shaft 33 provided on the screw 32, an extension base 34 rotatably connected to a lower end of the connecting shaft 33, an elastic expansion base 35 provided on the extension base 34 and disposed below the leg 2, an adjustment caster 36 rotatably connected to an expansion end of the expansion base 35, and a pair of support casters 37 rotatably connected to a bottom surface of the extension base 34. The rotation angle of the adjusting caster 36 around the connecting shaft 33 is-60 degrees to 60 degrees, that is, the rotation range of the adjusting caster 36 on both sides of the support leg 2 is kept within 60 degrees, such angle design ensures that the supporting caster 37 is always outside the support leg 2, and simultaneously, the connecting line between the adjusting caster 36 and the pair of supporting casters 37 forms a regular triangle structure enclosed outside the end of the support leg 2, so as to expand the ground-holding area.

The retractable seat 35 includes a sleeve 351 passing through the extension seat 34 and having a downward opening, a pair of compression springs 352 fixed to a top wall of the sleeve 351, a baffle 353 disposed at a lower end of the compression springs 352 and slidably connected to the sleeve 351, an adjusting column 354 disposed at a lower end of the baffle 353, an adjusting seat 355 disposed at a lower end of the adjusting column 354, and a retainer ring 356 disposed at an opening end of the sleeve 351 and sleeved outside the adjusting column 354. Wherein the adjustment caster 36 is rotatably connected to the adjustment seat 355, and the retainer 356 is used to limit the separation of the blocking plate 353 from the sleeve 351. The sleeve 351 and the adjusting column 354 form a telescopic structure, and pressure is applied to the adjusting seat 355 through the pressure spring 352 so as to force the adjusting caster 36 to abut against the ground.

The detailed working process of the embodiment is as follows: when a person lies or leans on the swivel chair in a flat way, one of the support legs 2 tilts backwards, and the triangular support component 3 of the other support leg 2 is separated from the ground, at this time, the pair of support casters 37 of the support leg 2 keeps supporting the five-pointed star feet at the outer side of the support leg 2, and at the same time, the telescopic seat 35 extends and forces the adjusting caster 36 to abut against the ground, so that the adjusting caster 36 and the pair of support casters 37 continue to keep a triangular support state, and the situation that the swivel chair on the five-pointed star feet is inclined or even topples over due to unstable gravity center is avoided.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
