Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1 and 2, a shock attenuation rattan chair, includes seat 1 and installs four buffering landing legs in seat 1 bottom, buffering landing leg includes inner skleeve 2, outer sleeve 3, base 6 and the piece that resets of fixed connection in inner skleeve 2 bottom, inner skleeve 2 fixed mounting has seted up venthole 4 on seat 1, inner skleeve 2 is last, outer sleeve 3 slidable mounting is in inner skleeve 2 below, base 6 installs in outer sleeve 3 bottom, has seted up venthole 5 on the outer sleeve 3 with venthole 4 homonymy, inner skleeve 2 and outer sleeve 3 sliding connection and the two contact site keep sliding airtight, venthole 4 and venthole 5 have the coincidence portion can supply gas to discharge, and when seat 1 pressure-bearing, inner skleeve 2 descends and makes its inside air pressure increase, slowly discharges from venthole 4 and venthole 5 coincidence department, provides the resistance for seat 1, realizes the effect that slows down the speed, and the piece that resets can provide the resistance for descending, and when pressure disappears, the piece that resets and promotes inner skleeve 2 and resumes the normal position.

Preferably, the restoring member is a spring 8, which is compressed when the seat plate 1 is not pressed.

Specifically, the air outlet groove 5 is vertically formed, the upper end of the air outlet groove is at the same horizontal height as the upper end of the air outlet hole 4, and the width of the air outlet groove 5 decreases from top to bottom, so that the area of the overlapped part of the air outlet groove 5 and the air outlet hole 4 decreases with the descending of the inner sleeve 2, and the air discharge speed decreases with the descending of the inner sleeve 2, so that the resistance force applied to the inner sleeve 2 increases with the descending of the inner sleeve 2.

Specifically, the upper end of the air outlet groove 5 is lower than the top end of the outer sleeve 3, when the damping rattan chair is suspended, the inner sleeve 2 slides outwards relative to the outer sleeve 3 under the thrust action of the spring 8, the air outlet hole 4 and the air outlet groove 5 do not overlap, and complete air tightness is realized between the inner sleeve 2 and the outer sleeve 3, so that the inner sleeve 2 and the outer sleeve 3 cannot be completely separated.

Specifically, a cross rod 9 for connecting two adjacent outer sleeves 3 is arranged between the outer sleeves 3, and the cross rod 9 is fixedly connected with the outer sleeves 3.

Further, the opposite side of inner skleeve 2 and venthole 4 is provided with fixed vertical sand grip, the opposite side of outer sleeve 3 and venthole 5 is provided with vertical spout, vertical sand grip and vertical spout sliding gas-tight connection make inner skleeve 2 and outer sleeve 3 only have relative motion in the vertical direction.

Further, a matched airtight thread is arranged between the base 6 and the outer sleeve 3, and the base 6 can be lifted through the airtight thread and used for adjusting the length of the buffering supporting leg so as to adjust the height of the seat plate 1.

In particular, the airtight threads comprise an external thread on the base 6 and an internal thread at the bottom of the outer sleeve 3, which can be adjusted in height to keep the four buffer legs at the same length by adjusting the visible height of the external thread on the base 6.

Furthermore, a convex ring 7 is arranged on the base 6, and the convex ring 7 is fixed at the bottom end of the base 6, so that the length of the supporting leg can be conveniently adjusted by rotating the base 6.
