Abstract

The utility model discloses a swivel chair, which comprises a chair seat, supporting bars and chair foot seats. Besides, the utility model is also provided with an upper turnplate and a lower turnplate in the shaft journal way, the supporting bar under the chair seat is divided into an upper supporting bar and a lower supporting bar which are respectively connected with the upper turnplate and the lower turnplate in the pivot way. The upper turnplate and the lower turnplate respectively corresponding with the supporting bars are provided with heaves, which are all provided with flumes declining towards the center. When in use, the upper turnplate can actuate the upper supporting bar to do the rotation relative to the lower supporting bar, and the chair seat is rotated to do the relative movement, thus the utility model is more agile and convenient than the habitually used articles.

Description

A kind of swivel chair

The utility model relates to leisure and uses chair, refers to a kind of swivel chair especially.

In the prior art, the structure of leisure usefulness chair mostly as shown in Figure 1, mainly by seat support 1, support bar 2, and chair foot pedestal establish for 3 groups to articulate and form, wherein support bar is established the below that is articulated in seat support 1 for 2 groups, but can't in certain space, do relative rotation after this seat support 1 and support bar 2 are affixed, convenient inadequately during use, lack flexibility.

The purpose of this utility model will provide a kind of seat support relatively turnable swivel chair exactly, so that more convenient, flexible when using.

For achieving the above object, the solution that the utility model is taked is a kind of swivel chair of design, comprise seat support, support bar and chair foot pedestal, in addition, also be provided with the top rotary table and the lower rotary table that connect by a pivot, and the support bar branch under the seat support is set as upper support bar and lower support bar and articulates with upper and lower rotating disk respectively and links to each other, and corresponding each support bar of upper and lower rotating disk is provided with projection, is equipped with centroclinal skewed slot on the projection.

The opposite face of described upper and lower rotating disk is respectively equipped with annular groove and reaches annular groove down, is embedded with annular ring in the upper and lower annular groove and reaches annular ring down, and be provided with and the contacted salient point of last annular ring in following annular ring.

Described last annular ring and following annular ring are one-body molded with upper and lower rotating disk respectively.

The opposite face of described top rotary table and lower rotary table is provided with circular groove, and then corresponding this circular groove of lower rotary table is provided with projection.

The proximal ends of described skewed slot is provided with the vertical hole with its perforation.

After adopting said structure, owing to have additional relatively turnable upper and lower rotating disk between the upper and lower support bar of the utility model seat support below, make seat support rotating freely of 360 ° in lower support bar work relatively, the product of commonly using are more convenient, flexible; And because the following annular ring that is embedded in the upper and lower rotating disk and the contact-making surface of last annular ring are provided with salient point, making the two is line contact rather than face contact when relatively rotating, and has reduced the two and has rubbed in relative rotation, makes rotation more nimbly and freely; And circular groove that upper and lower rotating disk sets up separately and projection can make the two location more accurate; In addition, the proximal ends of skewed slot be provided with its perforation vertical hole, can make upper and lower support bar by skewed slot in the vertical hole of axle steer, thereby the folding swivel chair.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

Fig. 2 is a schematic appearance of the present utility model;

Fig. 3 is the three-dimensional exploded view of the utility model turntable;

Fig. 4 is the assembled sectional view of the utility model turntable;

Fig. 5 is a folding state schematic diagram of the present utility model;

At first, see also Fig. 2, shown in Figure 3, swivel chair described in the utility model mainly is made up of seat support 1, support bar 2 and chair foot pedestal 3, it focuses on also being provided with top rotary table 4 and lower rotary table 5, and each support bar branch is set as upper support bar 21 and lower support bar 22 and articulates with top rotary table 4 and lower rotary table 5 respectively link to each other, and establish a rotating shaft 6 interspersed pivots and connect rotating disk 4 and lower rotary table 5.

The detailed structure of described top rotary table 4 and lower rotary table 5 can cooperate shown in Figure 4, corresponding respectively each support bar of top rotary table 4 and lower rotary table 5 is provided with

projection

41,51, and be equipped with the skewed slot 411,511 that tilts to center of turntable on the

projection

41,51, this skewed slot 411,511 just can be set corresponding upper support bar 21 and lower support bar 22 respectively,

projection

41,51 side also is provided with through hole 412,512, and through hole 412,512 can intert a rivet upper support bar 21 and lower support bar 22 are articulated in top rotary table 4 and lower rotary table 5 respectively.

In addition, the opposite face of upper and lower rotating disk can be respectively equipped with annular groove 42 and reach annular groove 52 down, and annular ring 8 under in upper and lower annular groove 42,52, being embedded with thickness respectively and its corresponding respectively last annular ring 7 reaching, and the salient point 81 with last annular ring 7 contacted somes is set on the following annular ring 8, make upper and lower rotating

disk

4,5 around the shaft 6 when doing rotation relatively, it is line contact rather than face contact that following annular ring 8 reaches the contact-making surface of going up annular ring 7, thereby reduce the friction of the two, prolong its service life; Simultaneously, can on the opposite face of top rotary table 4 and lower rotary table 5, circular groove 43 be set, and the projection 53 with circular groove 43 tablings is set on lower rotary table 5, when the two is more accurate, more stable to fashionable upper and lower rotating

disk

4,5 location that make.

In addition, annular ring 8 also can be one-body molded with top rotary table 4 and lower rotary table 5 respectively under aforementioned upward annular ring 7 reached.

The utility model in use, because the upper and lower rotating

disk

4,5 that pivot connects between the upper support bar 21 of its seat support below and the lower support bar 22 can 6 be done relative rotation around the shaft, therefore, when top rotary table 46 rotations around the shaft, can drive upper support bar 21 rotations, thereby the seat support that interlock upper support bar 21 supports rotates, and is more more convenient, flexible than the product of commonly using.

In addition, also can be on aforementioned protruding 41,51 skewed slot 411,511 connect with it near the setting of disk axes end vertical hole 413,513, upper support bar 21 that pivot respectively connects and lower support bar 22 are gone in vertical hole 413,513 to the axle center polymerization in by skewed slot 411,511 around axle, as shown in Figure 5, thereby the folding swivel chair, not only simply but also practical.
