Abstract

A tension fixed structure of a light box picture is provided, which is composed of a fixed part connected on a frame and a tension part. The fixed part is a caulking groove arranged on the frame; the tension part is formed by combination of a strip heave on both side walls of the caulking groove and an embedded flexible strip. The tension fixed structure is that the caulking groove is added in the sectional material of light box frame and the caulking groove is embedded with the flexible strip, which is simple, few in parts and easy in processing, fully adopts light box frame but not occupies useful space; corresponding positive and negative upper and lower smooth teeth are only processed on both side walls of the caulking groove; enough space is only left around the picture and is unnecessary to be processed; at the same time, flexible holddown tubes are embedded at intervals and are adjusted according to the requirements, thereby saving material and lowers manufacturing cost. When disassembling and replacing the picture, opening a cover board and pulling out the tail end of the fixed part of the picture in turn; pulling out the picture. The tension fixed structure is convenient and fast in disassembly and replacement, thereby not damaging the frame and ensuring repeated use of the light box frame.

Description

The tension fixed structure of lamp box picture

Technical field

The utility model relates to the vitals in a kind of lamp box, the tension fixed structure of the lamp box picture that particularly a kind of picture that is used to be strained and fixed uses.

Background technology

Prosperity along with expanding economy, market, the life cycle of lamp box advertisement is shorter and shorter, and the transposing frequency is more and more higher, for saving cost, need repeatedly reuse original lamp box and only the picture of lamp box is upgraded, changes, just being badly in need of having can fast quick-detach, the transposing picture, and can strain, the fixed mechanism of the flat picture that stretches tight.

Patent No. CN94243894.9 " lamp box picture tightening device " provides with the hold-down nut and the protruding tip and is fixed on the housing, set screw and hold-down nut are right after, locate by keeper, keeper with tighten dop and join, tighten in the dop and wear lining by pivot pin, lining is drawn from the opening part of tightening dop and is pressed on the protruding tip, and the edge of lining also need process, regulate because of connecting, so also need could use with instrument with screw, nut.

The device that also provides a kind of advertisement cloth can change at any time among the patent No. CN200420044285.0 " a kind of combined lamp case " according to user's needs, it is female sign indicating number son to be linked be connected on the screw rod, and two location-plates of granny rag device are stuck in the groove of the young button of sign indicating number, be placed in the granny rag device on the Lamp box frame with the pole of granny rag device equal in length, being processed with multiple layer around the advertisement cloth is enclosed within outside the pole, screw and pull out from the bottom of carriage after screw rod is tightened advertisement cloth, need the granny rag device to be installed at four jiaos of places of lamp box, could change painting canvas after each pole need being taken out from the granny rag device, it is big to take the useful space, structure is complicated, needs could operate with instrument.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of tension fixed structure of lamp box picture is provided, and simple in structure, part is few, directly utilizes Lamp box frame to set up caulking groove, does not take the useful space, install, the dismounting picture is convenient, fast.

The technical scheme in the invention for solving the above technical problem is: the tension fixed structure of lamp box picture, formed by the fixed part and the tension section that are connected on the frame, the caulking groove of described fixed part on framework, being provided with, described tension section cooperates with the elastic layering of embedding by the strip projected parts on the caulking groove two side and is formed, the cross section of described strip projected parts is a serrate, have on the described caulking groove left side wall and go up, down suitable tooth is arranged on the right side wall, and the and arranged on left and right sides wall is parallel along tooth.

Compared with prior art, advantage of the present utility model is: this tension fixed structure is directly to utilize to set up caulking groove in the section bar of Lamp box frame, and embeds the elastic layering formation in caulking groove again.Simple in structure, part is few, easy processing, made full use of Lamp box frame, but do not take its useful space, only on the two side of caulking groove, process positive and negative corresponding upper and lower along tooth, as long as and reserve enough blank around the picture, need not other processing, reduced operation, the elastic compression pipe can embed at interval simultaneously, carries out density as required and regulates, and material is economized, low cost of manufacture.Dismounting, transposing be during picture, as long as open cover plate, the tail end of the fixed part of picture is pulled outwardly successively, and dismounting, transposing are convenient, fast, do not need instrument, also do not damage frame, and frame can be reused the normal phase.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Frame links into an integrated entity by the

framework

4 or 4 of four sides ' and cover plate 5 or 5 ' hinged or with screw and forms, the framework centre have caulking groove 2 or 2 '.

Caulking groove 2 or 2 ' the two side on corresponding strip projected parts is arranged, the cross section of strip projected parts is a serrate, and the sawtooth on the left side wall be last along tooth 22 or 22 ', sawtooth on the right side wall for down along tooth 21 or 21 ', be that zigzag fashion is identical, direction is opposite, and the and arranged on left and right sides wall is parallel.

Elastic layering is that elastic compression pipe 3 its cross sections are tubular, and having on the neighboring increases friction and the fine strip shape projection parallel with the pipe center, and elastic compression pipe 3 is a length 60～80 millimeters pipe section, as shown in Figure 1 and Figure 2.

During use, earlier in picture 1 blank space all around, at interval 300～400 millimeters places put elastic compression pipe 3 successively, firmly picture 1 and elastic compression pipe 3 are pressed into together caulking groove 2 internal fixation on the framework 4 then, when being pressed into picture, the surrounding of picture firmly is pulled outwardly, picture 1 is stretched even tauter,, can suitably shortens the distance of placing elastic compression pipe 3 if the lamp box area is bigger, promptly increase the quantity of elastic compression pipe, stretch tight very tight not laxly to guarantee picture.

If will dismantle, when changing picture 1, only need open cover plate 5, the tail end of fixed part around the picture 1 is pulled outwardly successively gets final product.

At this moment because of last direction along tooth 22 make progress, under the effect of external force and elastic compression pipe 3, along last suitable tooth 22 upward to just picture 1 being pulled out transposing, easy to use, quick smoothly from tail end.
