Abstract

The utility model discloses a fixing device for a canvas of an advertising lamp box. The fixing device comprises a lamp box body, a canvas supporting frame arranged in the lamp box body and the canvas spread on the canvas supporting frame, wherein the edges of the canvas extend out of corresponding edges of the canvas supporting frame and are respectively provided with a plurality of buttonholes. The fixing device further comprises a plurality of tension springs, wherein one end of each tension spring is hooked to one corresponding buttonhole, and the other end of each tension spring is fixed to the lamp box body. By means of the fixing device for the canvas of the advertising lamp box, the canvas can be fixed to the lamp box body and spread flat, both time and labor are saved, material consumption is reduced, and working difficulty and use cost are greatly reduced.

Description

The stationary installation of advertising lamp box painting canvas

Technical field

The utility model relates to the stationary installation of publicity painting canvas in a kind of advertising lamp box.

Background technology

Existing advertising lamp box, mainly comprise: the light box being spliced to form by section bar and painting canvas carriage, the painting canvas that is printed on promotional content spreads on described painting canvas carriage, each selvedge of painting canvas extends outside the corresponding edge of painting canvas carriage, described in each, on selvedge, be equipped with multiple buttonholes, band or steel wire fasten on described light box through described buttonhole., there is defect in this fixed sturcture of painting canvas: when fixing painting canvas, band or steel wire need to pass buttonhole, then fastens on light box, not only time-consuming but also require great effort; The band at each position or steel wire are wayward because of the tightness fastening, thereby pulling force is inhomogeneous, causes painting canvas smooth not; Fasten at every turn and all need new band or steel wire, band or steel wire waste are serious.

Summary of the invention

The purpose of this utility model is to provide a kind of stationary installation of advertising lamp box painting canvas, can fast painting canvas be fixed on light box, and painting canvas sprawl smooth, time saving and energy saving, save consumptive material, greatly reduce difficulty of construction and use cost.

For achieving the above object, the utility model adopts following technical scheme:

A kind of stationary installation of advertising lamp box painting canvas, comprise light box, be arranged at the painting canvas carriage in light box and spread in the painting canvas on described painting canvas carriage, each selvedge of painting canvas extends outside the corresponding edge of painting canvas carriage, on each described selvedge, be equipped with multiple buttonholes, also comprise multiple extension springs, described in each, extension spring one end hook is hung on corresponding buttonhole, and the other end is fixed on light box.

Open Side Down for the hook on buttonhole of being hooked in of its upper end of described extension spring.

Described hook departs from the axis of extension spring.

The spring coil of described extension spring lower end has at least two circles to form stage clip section, and the spring coil of described stage clip Duan Yuqi top connects by elater, and described stage clip section is arranged in the draw-in groove being arranged on light box.

Compared with prior art the beneficial effects of the utility model are: owing to adopting technique scheme, described in each, extension spring one end hook is hung on painting canvas on corresponding buttonhole, the other end is fixed on light box, this structure, in the time of fixing painting canvas, can fast painting canvas be fixed on light box, not only save time but also laborsaving; Because the elastic force of each spring is identical, thereby tension uniform, cause painting canvas smooth; Extension spring can be reused, and has saved consumptive material, greatly reduces difficulty of construction and use cost.
