Description

A kind of multipurpose section bar

Technical field

The present invention relates to a kind of section bar, especially a kind of for the multipurpose section bar that connects row's structure of chair.

Background technology

Row's chair generally is applied to large-scale places such as assembly hall, airport, stadium, dining room, existing row's structure of chair mainly comprises foot rest, cross bar and several seats, the cross bar two ends are located on the foot rest, and seat frame is located on the cross bar, are connected and fixed by bolt between each parts, the structure of this type of row's chair is single, can not adjust the position of seat, poor expandability, and syndeton is built on the sand, use a large amount of bolts to fix in installation process, operation is loaded down with trivial details, time-consuming.

And general cross bar or foot rest, it adopts the tubular structure of square or arc, with respect to cylinder-like structure, has higher stability and load bearing stength, but lack row's chair parts that corresponding connector connects difformity and different angles simultaneously always, so that be difficult to improve the quality of row's chair.

Summary of the invention

In order to solve the problems of the technologies described above, the invention provides a kind of multipurpose section bar, this section bar with Connection Block structure forms according to leg-of-mutton characteristics design, can connect combination in a plurality of angles row's chair is expanded, simple and practical, easy to assembly, applied widely.

To achieve these goals, the technical solution adopted in the present invention is:

A kind of multipurpose section bar, comprise the section bar main body, described section bar main body is triangular structure, its bottom surface is provided with groove, two ends, the bottom surface formation runners that stretches out, the section bar main body is provided with the through hole communication groove, described groove is the isosceles right triangle groove, described right angle is positioned at the top, bottom surface, the foot rest that this section bar main body can be used for fixing row's chair also can be used for supporting bable tops or seat, when the applying of two section bar main body runners symmetry on the ground, two groove combination form square groove position and carry out extending transverselyly, and the side connects foot rest by through hole is set, armrest or other attaching parts are vertically expanded.

As further improvement in the technical proposal, described runners is provided with screw, is used for being connected and fixed the section bar main body by bolt, installs simple and convenient.

As further improvement in the technical proposal, the inclination angle, side of described section bar main body is greater than the inclination angle, side of groove, and the spacing at the top of section bar main body and the right angle of groove is 2.5cm-3cm, when two section bar main body combined support cross bars, this structure adds heavy section to the support dynamics of cross bar, more saves to take up room; When connecting foot rest, bipod inserts and makes it have enough spaces to adjust angle in the section bar main body.

As first kind of embodiment of technique scheme, described through hole is located at the top of section bar main body, and this embodiment is applied to expand in the vertical direction connection.

As second kind of embodiment of technique scheme, described through hole is located at the side of section bar main body, and this embodiment is applied to expand in the triangle side direction.

A kind of multipurpose section bar provided by the invention has following beneficial effect to be:

This section bar adopts triangular structure to design, its resistance to compression, resistant to bending ability are strong, the bottom surface arranges runners and is used for connecting the location, the position of through hole can be set on the side as required, and can be combined to form quadrilateral structure by two section bar main body symmetries, realize the connection combination of multi-angle at fore-and-aft plane; Simultaneously, two right angle grooves are combined to form the groove position of square structure, are used for connecting expansion, and the structure of arranging chair is simplified in the compound mode variation greatly, reasonable in design, province's material, durable.

The specific embodiment

A kind of multipurpose section bar, comprise section bar main body 1, described section bar main body 1 is triangular structure, its bottom surface is provided with groove 11, the two ends, bottom surface stretch out and form runners 14, described runners 14 is provided with screw 13, be used for being connected and fixed section bar main body 1 by bolt, install simple and convenient, section bar main body 1 is provided with through hole 12 communication groove 11, the shape of through hole 12 is decided according to the geomery of attaching parts, described groove 11 is the isosceles right triangle groove, and described right angle is positioned at bottom surface top, and the foot rest 4 that this section bar main body 1 can be used for fixing row's chair on the ground, also can be used for connecting supporting bable tops or seat, when two section bar main bodys, 1 runners, 14 symmetries were fitted, two grooves 11 were combined to form square groove position, are used for laterally connecting row's chair cross bar 2 and expand, the side connects foot rest 4 by through hole 12 is set, armrest 5 or other attaching parts, through hole 12 adopts welding fixing with the joint of described parts.Because this section bar main body 1 forms according to leg-of-mutton characteristics design, its resistance to compression, resistant to bending ability are strong, make up the compound mode variation according to difform row's structure of chair.

Preferably, the inclination angle, side of described section bar main body 1 is greater than the inclination angle, side of groove 11, and the spacing at the right angle of the top of section bar main body 1 and groove 11 is 2.5cm-3cm, when two section bar main bodys, 1 combined support cross bar 2, this structure adds heavy section to the support dynamics of cross bar 2, more saves to take up room; Simultaneously, when being connected with foot rest 4, bipod 4 inserts and makes it have enough spaces to adjust angle in the section bar main body 1.
