Abstract

The utility model relates to a base for chairs, wherein a circular ring chassis is two half circular ring body ends which are provided with horizontally mutually meshed rabbets and mortises and vertically mutually meshed rabbets and mortises; the rabbets and the mortises are spliced together by adhesive; a support column is arranged on the inner side of the circular ring chassis; the rabbets are meshed with the mortises by the adhesive. The utility model adopts the horizontal connecting and the vertical connecting of the rabbets and the mortises in a splicing region, so the spliced circular ring chassis can not generate horizontal or vertical displacement in the splicing region. Because the support column is arranged on the inner side of the circular ring chassis and the rabbets are meshed with the mortises by the adhesive, the utility model has the advantages of large contact area, good firmness and long service life.

Description

The seat base

Technical field:

The utility model relates to a kind of base of seat.

Background technology:

The base of seat has various ways available in existing technology, for example five wheeled, four pin console modes, back-shaped tubular type, certainly also have circular ring type, the existing circular ring type base employing level or the splicing that vertically is meshing with each other, shortcoming is to control one degree of freedom.For example level engagement can only be controlled vertical aspect and can not produce displacement, the fore-and-aft direction of level have produce displacement may, and support column is installed on the upper surface of base, and is firm inadequately, influences service life.

The utility model content:

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of level, the vertical support column that can not produce displacement that more firm seat base is installed.

The technical scheme of the utility model seat base comprises annulus chassis and the support column that is installed on the annulus chassis, described annulus chassis is that the end of two semi-circular ring shapes both had been provided with the level tenon tongue-and-groove that is meshing with each other, also be provided with the tenon tongue-and-groove viscose glue that vertically is meshing with each other and be spliced, described support column is installed on the inboard tenon tongue-and-groove viscose glue engagement on annulus chassis.Described level is meshing with each other the tenon tongue-and-groove at the first half on annulus chassis, also can be in Lower Half, and the described tenon tongue-and-groove that vertically is meshing with each other also can be at the first half in the Lower Half on annulus chassis.

The beneficial effect of the utility model seat base is: adopt the tenon tongue-and-groove of existing level to also have the connection of vertical tenon tongue-and-groove in splice region, make splicing annulus chassis originally can not produce level or vertical displacement in splice region, the inboard tenon tongue-and-groove engagement that support column is installed on the annulus chassis can increase contact area, increased fastness, increased the service life.

Description of drawings:

Fig. 1 is the front view of the utility model seat base;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1;

Illustrated the utility model seat base, comprise annulus chassis 1 and be installed on the The One On The Chassis support column 2 of annulus, the end that its annulus chassis 1 is two semi-circular ring shapes both had been provided with the level tenon tongue-and-groove 6 that is meshing with each other, also being provided with tenon tongue-and-groove 5 viscose glues that vertically are meshing with each other is spliced, its support column 2 is installed on the inboard tenon tongue-and-groove 7 viscose glues engagement on annulus chassis 1, its level is meshing with each other tenon tongue-and-groove 6 at the first half on annulus chassis 1, and the Lower Half of tenon tongue-and-groove 5 on annulus chassis 1 vertically is meshing with each other.Hole 3 and hole 4 are handrail installing holes.

Certainly; annulus chassis 1 if two or more circular arc body shape at the intermeshing tenon tongue-and-groove 6 of the existing level of splicing place; also has the splicing of vertical intermeshing tenon tongue-and-groove 5 viscose glues or pin attitude, all within protection domain of the present utility model.
