The specific embodiment

Core of the present utility model provides a kind of simple in structure, easy to connect and be easy to install the support section bar of exhibition booth decorative parts.

In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Please refer to Fig. 1,2, the cross section of the section bar 10 in this specific embodiment is square, its inside is the cavity 11 of hollow, be formed with the circular fin 12 that extends along the profile length direction at Si Jiaochu, section bar and fin 12 are integrally formed, the connecting hole 13 that connects before and after offering on the fin 12, connecting hole 13 is connected with cavity 11 by the opening 14 towards the section bar center on the fin.

Have " U " connected in star 15 on two outer surface adjacent of section bar, its opening both sides have makes position-limited edge that A/F dwindles along 151.This groove is mainly used in the parts of clamping as hook, adapter and so on, and then the decorative parts of exhibition booth is installed by these parts.

Be fitted with steel plate 16 on section bar 10 two other outer surface adjacent, the both sides of steel plate 16 downwards, outwards two an angle of 90 degrees of inverse bending form plug side 161, have and the suitable shallow slot of steel plate width on 10 two adjacent external surfaces of section bar, steel plate 16 inserts in the relative socket in shallow slot both sides by its plug side 161, after the insertion, the section bar outer surface at the end face of steel plate 16 and its place flushes.The main effect of this steel plate 16 is to form the steel position on the outer surface of section bar 10, and then can interconnect with the parts to be installed with magnetic, is the aesthetic property that improves section bar 10, can be to steel plate 16 processing of spraying paint.

Owing to have certain interval between steel plate 16 and the shallow slot, for preventing that the steel plate pressurized is out of shape, be suppressed with the groove 162 and two that extends along the profile length direction together at the steel plate middle part and be listed as the circular concave point 163 that is positioned at the groove both sides, groove 162 and concave point 163 are in steel plate back side projection and be resisted against the shallow slot bottom, can play the multi-point support effect, thereby prevent steel plate 16 collapse-deformations, can also increase the magnetic area simultaneously, and then strengthen absorption affinity.

Please refer to Fig. 3, use the section bar 10 in the foregoing description to can be assembled into a plane framework, dock mutually by section bar connector 20 between the end of each section bar, its steel plate 16 all is positioned at the front, the decorative panel 30 (or bunting etc.) that so just the back side can be had magnetic stripe is adsorbed on the framework, form the exhibition booth structure of an integrally closed, as the first half is shown in the drawings.If necessary, " U " connected in star that also can make horizontal section bar among the figure is towards the top, and then the hook of packing into is reinforced the parts of absorption.

Please refer to Fig. 4, use the section bar 10 in the foregoing description to can be assembled into a hanger, dock mutually by section bar connector 20 between the end of each section bar, " U " connected in star of the horizontal section bar of upper edge is towards the top, be connected with two hooks 40 on it, drawing board 50 is hooked on the hook 40 by two extension caps 51 at its top.

Please refer to Fig. 5, has " U " connected in star 15 on two adjacent external surfaces of this section bar, and the central vertical projection of two other adjacent external surfaces has floor 17, two outer surfaces in floor 17 both sides respectively cementation the barb band 18 of velcro is arranged, the decorative panel (or bunting etc.) that so just the back side can be had the lint band sticks on the framework, form the exhibition booth structure of an integrally closed, floor 17 among the figure can play position-limiting action at interval, so that decorative panel is bonded in exactly in each window of framework.Because all the other structures and a last embodiment are basic identical, just repeat no more here.

Please refer to Fig. 3, Fig. 4, section bar assembly provided by the utility model is assembled by above-mentioned section bar 10 splicings, connects by section bar connector 20 between the section bar.

More than section bar provided by the utility model is described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present utility model.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
