Description

A kind of truss device that is used for the advertisement frame

Technical field

The utility model relates to a kind of supporting frame that is used for the advertisement frame, particularly a kind of truss device.

Background technology

At present as the outdoor advertising frame, and the stage background frame and the exhibition space-stop rack in employed column and crossbeam, its column height and crossbeam length are generally greater than 3m, be fixedly connected metal framework, general employing length is 1m, 1.5m, the fixed frame of 2m etc. is assembled and is connected into desired height or length, or directly make the framework of an integral body, and each lateral width of lengths of frame direction is the width of actual required advertisement frame, its weak point is: 1. because this framework volume is bigger, need expend a large amount of metal materials, cause own wt bigger than normal, can cause loading and unloading simultaneously, transportation, store very inconvenience; 2. mount and dismount time and effort consuming, the framework need one that assembling connects save up to be built, down dismounting again after the use; And the setting of integral frame and set level and need more manpower or use hanging device; 3. big owing to the framework volume, Heavy Weight, and certain operation height is arranged, there are many potential safety hazards of injury to personnel in uses such as installation, dismountings.

Summary of the invention

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the telescopic truss device that is used for the advertisement frame.

The purpose of this utility model is achieved in that a kind of truss device that is used for the advertisement frame, it is characterized in that: this device comprises several interconnective truss sides; Each described truss sides comprises two groups of connecting rods interlaced, that flexibly connect at the middle part, and every group of described connecting rod is parallel to each other; The end of the described connecting rod of the both sides of described truss sides flexibly connects successively and is flexible truss cylinder; This truss device generally consists of good by 3～6 truss sides.

The top of adjacent above-mentioned truss sides and bottom the end of corresponding two described connecting rods that intersect flexibly connect through last slip hinge and lower slider hinge respectively, and the end of two groups of described connecting rods that the correspondence in the middle of it intersects flexibly connects through the angle hinge.

The described connecting rod of above-mentioned truss sides in the middle flexible connection or be being connected of cooperating of hole and pin, or be being connected of hole and bolt cooperation.

The flexible connection of the above-mentioned hinge of go up sliding, lower slider hinge and angle hinge and described interlinking lever end or be being connected of hole and pin cooperation, or be being connected of hole and bolt cooperation.

The upper end of the above-mentioned strand of upward sliding and the lower end of described lower slider strand are respectively arranged with joint pin, so that assemble connection with the required supporting member that is connected.

Truss device of the present utility model can be used as the advertisement frame and stage background frame, the column of opening up space-stop rack and crossbeam use.When using as column, only need the joint pin of its lower slider hinge is flexibly connected with the truss seat that has Poewr transmission mechanism, by Poewr transmission mechanism this truss device can be connect and need random lifting, change its height, the crossing angle of the basifacial first group of connecting rod of each truss of truss device changes during rising, produce the identical axially-movable that makes progress when causing the upper end of this group connecting rod to produce the radial motion at center to the inside, and all the other connecting rods that drive the phase hinge produce identical motion; During decline, otherwise then.When using for crossbeam, earlier upper and lower slip hinge end is flexibly connected with connection box respectively, connection box is connected with two friendship node places as the connecting rod on the top, a side of the truss device of column respectively again, when change between two column truss devices apart from the time, then the crossbeam truss can carry out corresponding dilatation.

In addition, dispose identical with the signpost profile, as to be used for the supporting of profile lining forming supporter on the supporting base that can connect, to save the manufactured materials and the weight of signpost in the end and the lower slider hinge bottom of the last hinge of sliding.

In a word, truss device of the present utility model adopts simple bar linkage structure, and the material of use is relatively economized, and is in light weight, the intensity height; When not using, whole truss device becomes folded state, and volume is little, is convenient to carrying, stores.
