Abstract
The invention discloses a foldable revolving chair leg. The chair leg comprises a casing seat and five support legs which are uniformly distributed on the outer circumference of the casing seat and extend outwards, wherein each support leg is connected with a crank rocker mechanism; the crank rocker mechanism comprises a pair of cranks, a pair of connecting rods and a rocker; the back end of the rocker is pivoted with the front end of the support leg, while the front end is provided with a roller installing seat; the pair of cranks and the pair of connecting rods are arranged on both sides of the support leg respectively; one end of a crank is hinged with the middle of the support leg, while the other end is hinged with one end of a connecting rod; and the other end of the connecting rod is hinged with the rocker. The chair leg has the advantages of folding the revolving chair leg, reducing size, contributing to packing and transporting products and lowering transportation cost.
Description
Technical field
The present invention relates to a kind of swivel chair pin that is used for swivel chair, particularly a kind of swivel chair pin that can fold.
Background technology
Along with the swivel chair industry is constantly upgraded, the swivel chair trading volume is also in continuous rising.In the swivel chair transaction, how to improve the vanning amount of product, be that enterprise practices thrift cost, enlarge a kind of valid approach in market.
As shown in Figure 1, existing common swivel chair pin (being commonly called as star base) volume is big, and relatively wasting space has taken the space greatly when vanning, and the vanning amount is difficult to improve always.
In addition, the purposes of swivel chair is variation more also, and common swivel chair is used for the occasion of handling official business more, rotates freely above the people is sitting in; But except sitting, people also think and can partly overlie, and are used for having a rest; But the swivel chair pin diameter for common swivel chair is all smaller, and the people lies in to be easy to generate on the swivel chair and tumbles, if strengthen the diameter of swivel chair pin; Though can satisfy the requirement of partly lying, transportation gets up relatively to take up room, and the vanning amount only can be littler.
Summary of the invention
The present invention is directed to the deficiency that exists in the above-mentioned prior art, provide a kind of volume to reduce, can improve the vanning amount, practice thrift the folding swivel chair pin of cost.
Technical scheme of the present invention is achieved in that
A kind of collapsible swivel chair pin; Comprise casing seat and five legs that are uniformly distributed in the casing seat excircle and outwards stretch, each leg all is connected with crank and rocker mechanism, and described crank and rocker mechanism comprises a pair of crank, pair of links and a rocking bar; The rear end of rocking bar and the front end of leg articulate; The front end of rocking bar is provided with the roller mount pad, and a pair of crank, pair of links are divided into the both sides of leg, and an end of crank and the middle part of leg are hinged; One end of the other end of crank and connecting rod is hinged, and the other end and the rocking bar of connecting rod are hinged.
As preferably, the length sum of crank, connecting rod less than the pin joint of crank and leg pin joint to the distance of leg front end and leg front end to rocking bar and connecting rod apart from sum.Thus, when normal operating condition, under the gravity effect, crank, connecting rod draw a straight line, and crank, connecting rod and leg, rocking bar surround a triangle, and rocking bar guarantees that to the direction bending certain angle of casing seat it can normally use.
Adopted the principle of the present invention of technique scheme and the advantage that has to be:
Each leg of swivel chair pin of the present invention all is connected with a crank and rocker mechanism, and the roller mount pad is arranged on the front end of rocking bar, and when folding, crank pivots, and drivening rod rotates, and connecting rod drives rocking bar and pivots, and realizes folding.Normally use like need, along counter-rotation, rocking bar is flipped out on crank; Then swivel chair pin level is placed on the ground, at this moment, because the crank and rocker mechanism gravitate; The compressing rocking bar forces crank and connecting rod to be linked to be a straight line, and rocking bar and leg are angled; Leg, rocking bar, crank and connecting rod constitute a triangle, reach a balance (promptly utilizing the principle that has the dead point in the crank and rocker mechanism).
The present invention can realize folding to the swivel chair pin, thereby has reduced volume, helps the vanning and the transportation of product, has reduced cost of transportation.

The specific embodiment
The specific embodiment of the present invention is following:
Embodiment: like Fig. 2, Fig. 4, shown in Figure 5, a kind of collapsible swivel chair pin comprises casing seat 1 and five legs 2 that are uniformly distributed in casing seat 1 excircle and outwards stretch; Each leg 2 all is connected with crank and rocker mechanism; Described crank and rocker mechanism comprises a pair of crank 3, pair of links 5 and a rocking bar 4, and the front end of the rear end of rocking bar 4 and leg 2 articulates, and the front end of rocking bar 4 is provided with roller mount pad 6; A pair of crank 3, pair of links 5 are divided into the both sides of leg 2; One end of crank 3 and the middle part of leg 2 are hinged, and an end of the other end of crank 3 and connecting rod 5 is hinged through bearing pin a7, and the other end of connecting rod 5 and rocking bar 4 are hinged.
As shown in Figure 3, crank 3 is hinged through bearing pin a7 with connecting rod 5, and crank 3 is hinged through bearing pin b8 with leg 2, and leg 2 is hinged through bearing pin c9 with rocking bar 4, and rocking bar 4 is hinged through bearing pin d10 with connecting rod 5; Bearing pin b8 to the distance of bearing pin a7 and bearing pin a7 to bearing pin d10 apart from sum less than bearing pin b8 to the distance of bearing pin c9 and bearing pin c9 to bearing pin d10 apart from sum.
When needs fold the swivel chair pin, give crank 3 downward power of bearing pin a7 with connecting rod 5 hinged places, force crank 3 to be done and clockwise rotate; Drivening rod 5; Connecting rod 5 drives rocking bar 4 then and does and turn clockwise, and reaches folding purpose, and folded state is as shown in Figure 3.
