Specific embodiment

To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face combines specific embodiment, and the utility model is further described.

Embodiment 1

As shown in Figure 1, a kind of flexible connection node of seat, including upper supporting beam 700, lower supporting beam 800 and by rubber The elastic construction that block 200, fixed lower cover 300, movable top lid 500 form.The top and bottom of rubber block 200 are bonded with respectively Adhesive plate, lower adhesive plate 100, upper supporting beam 700 and lower supporting beam 800 are individually fixed in adhesive plate, in lower adhesive plate 100 The heart.Fixed 300 main body of lower cover is U-shaped, is nested on the lower half portion of rubber block 200 and is fixed on lower adhesive plate 100, bottom Portion center is pierced by for lower supporting beam 800 equipped under shed and connect with the fixed part of seat.It, can be into protect lower supporting beam 800 Under shed is extended downwardly to one step and is bonded the protection shell that the lower setting of supporting beam 800 forms lower supporting beam 800.Movable top lid 500 be inverted U-shaped lid, is located at the top of rubber block 200, and there is end face center upper opening to be pierced by for upper supporting beam 700. Opening is the tubular opening to raise upward.

Upper opening inner sidewall is equipped with internal screw thread, upper supporting beam 700 is equipped with external screw thread 702, is threadedly coupled therebetween.Upper branch 702 the top of external screw thread of support beam 700 is equipped with circlip 701 and limits the scope of activities of movable top lid 500.Circlip 701 It can be substituted using with the integrally formed stop collar of upper supporting beam 700 or retention bead.Movable top lid 500 can be along upper support Beam 700 is realized and is moved up and down by rotating, and is opened and (is kept also with moving up and down between bottom and fixed lower cover 300 Certain distance), when movable top lid 500 as shown in Figure 1 engages (the two contacts) with fixed lower cover 300, rubber block 200 is locked； When movable top lid 500 as shown in Figure 2 is separated with fixed lower cover 300, at this point, 200 adjustable angle of rubber block.To avoid movable top lid 500 or both fixed lower covers 300 joint damage, fixed lower cover 300 is equipped with 500 joint of movable top lid for buffering Rubber ring 400 or soft silica gel circle.

For the rotation convenient for controlling movable top lid 500, the present embodiment has added one upwards at the top of movable top lid 500 The housing 600 of protrusion, top center are equipped with the opening passed through for supporting beam, and the bottom of housing 600 is superimposed and is fixed on activity The top of upper cover 500.Housing 600 can all cover movable top lid 500 with supporting beam, can play certain dust-proof work With.600 side wall of housing is fixed with turntable 601, bracelet or handle, and user can be turned by holding turntable 601, bracelet or handle Dynamic movable top lid 500, moves up and down it in upper supporting beam 700.Turn further to protect foreign matter not enter its internal influence Dynamic, the opening edge edge of housing 600 supporting beam 700 can tilt upwards, and form acute angle between upper supporting beam 700.

Movable top lid is arranged with scalable dust cover 900, scalable dust cover 900 below 500 top to fixed lower cover 300 Top, an opening being pierced by for supporting beam or support rod is respectively provided in bottom centre, be open opposite with supporting beam or support rod Sealing.Scalable dust cover 900 specifically may be selected using flexible telescopic tube or bellows made of plastic material, for connection The dominant structural moieties of node carry out dust seal.

Embodiment 2

Be in place of the present embodiment and the difference of embodiment 1: fixed lower cover 300 and the joint of movable top lid 500 are outside The jointing edge of protrusion.Jointing edge is and fixes lower cover or the integrally formed outer edge outwardly protruded of movable top lid, has into one The step limitation movable effect of movable top lid.

Based on above-mentioned, the utility model provides a kind of flexible connection node of seat, by upper supporting beam 700, under By a flexible rubber block connection between supporting beam 800, make supporting beam 700 can relative to lower supporting beam 800 to The twisting of the multiple directions such as front, rear, left and right, and then realize the multidirectional swing of chair cushion, enable the user of seat thereon that can sit Movable buttocks, waist and leg under appearance state substantially reduce or reduce because of various uncomfortable or disease caused by sedentary, Its is structurally reasonable, easy to use.

As known by the technical knowledge, the utility model can pass through other essence without departing from its spirit or the reality of essential feature Scheme is applied to realize.Therefore, embodiment disclosed above, in all respects are merely illustrative, and are not only 's.All changes that come within the scope of the invention or equivalents of the invention are by the utility model packet Contain.
