Abstract

A sun umbrella base comprises an inserting tube (1) and a stabilizing plate (6). The sun umbrella base is characterized in that a plurality of supporting rods (2) are fixed radially at the periphery of the inserting tube (1) along a horizontal direction; a locating seat (3) is fixed on each supporting rod (2); a supporting sleeve (4) is fixed at the top end of each supporting rod (2); an axial line of the supporting sleeve (4) is parallel with that of the inserting tube (1); a rotating rod (5) is arranged in the supporting sleeve (4); a stabilizing rod (51) is fixed at the bottom of the rotating rod (5); the stabilizing plate (6) is fixed at the bottom of the top end of the stabilizing rod (51); and a cap (56) is arranged at the top of the rotating rod (5). The stabilizing rod (51) can be rotated to a position orienting to the axial line of the adjacent supporting sleeve (4) from a position at the top end of the stabilizing rod (51) away from the maximum radius of a circle center of the inserting tube (1); when the sun umbrella base is utilized, the stabilizing rod (51) can be rotated and expanded such that a larger contact area is provided between the sun umbrella base and a ground; when folded, the sun umbrella base is of a square shape and only occupies 10% space compared with the space of the sun umbrella base during use; and the shape of the sun umbrella base is changed to ensure that the sun umbrella base has stronger stability and can be convenient to move and carry.

Embodiment

Now contrast Fig. 1-Fig. 5 embodiments of the invention are described.

A kind of parasol base comprises plug-in mounting pipe 1, strut 2, positioning seat 3, supporting sleeve 4, swingle 5, rear stabilizer 51, steadying plate 6, along continuous straight runs is the radial some struts 2 that are fixed with around the described plug-in mounting pipe 1, be fixed with positioning seat 3 on the strut 2, strut 2 tops are fixed with supporting sleeve 4, the parallel axes of the axis of supporting sleeve 4 and plug-in mounting pipe 1, be provided with swingle 5 in the supporting sleeve 4, swingle 5 bottoms are fixed with rear stabilizer 51, at the bottom on rear stabilizer 51 tops welding fixing-stable plate 6, the top of swingle 5 is provided with anticreep plate 56, and the rotated position of the center of circle maximum radius that rear stabilizer 51 can be from rear stabilizer 51 tops apart from plug-in mounting pipe 1 is to the position of the axis that points to adjacent supporting sleeve 4.

When rear stabilizer 51 was in deployed position, there was maximum radius on rear stabilizer 51 tops apart from the center of circle of plug-in mounting pipe 1, in described deployed position, in the face of the axial direction of positioning seat 3 is established a locating slot 54 on the wall of establishing a pilot hole 55, swingle 5 on the wall of supporting sleeve 4.When rear stabilizer 51 was in retracted position, rear stabilizer 51 rotated the axis that points to adjacent supporting sleeve 4 along clockwise direction, established an anti-slip tank 53 at described retracted position in the face of the axial direction of positioning seat 3 on the wall of swingle 5.
