Description

Technical Field

[0001] The invention relates to the field of advertising light boxes, in particular to an advertising light box which is convenient for replacing advertising cloth. Background Art

[0002] An advertising light box is an advertising carrier with a box-type hollow structure. Traditional advertising light boxes are mostly made of aluminum alloy. The advertising cloth is fixed on the aluminum alloy light box, and the advertising content on the advertising cloth is displayed through the light source in the light box. Since the advertising cloth is fixed on the aluminum alloy light box, when the advertising cloth needs to be replaced, the aluminum alloy light box needs to be disassembled first, and then the advertising cloth is replaced, which makes the replacement of the advertising cloth cumbersome and inconvenient. Summary of the invention

[0003] The purpose of the present invention is to provide an advertising light box which is convenient for replacing advertising cloth, so as to overcome the above-mentioned defects in the prior art.

[0004] According to the present invention, an advertising light box that is convenient for replacing advertising cloth comprises a base and a support plate fixed to the upper end surface of the base, a box body is arranged on the upper side of the support plate, the cross section of the box body is in a "U" shape, box plates are fixed to the upper and lower end surfaces of the box body, the box plate on the lower side is fixed to the upper end surface of the support plate, cover plates are rotatably connected to the upper and lower side walls of the box body, two symmetrically arranged clamping plates can be clamped in the box body, clamping seats are fixed to the upper and lower ends of the clamping plate, a winding shaft is detachably connected between the two clamping seats, an advertising cloth is arranged between the winding shafts on the left and right sides, the two side edges of the advertising cloth are respectively fixed to the outer periphery of the two winding shafts, and the pattern part of the advertising cloth is located between the two cover plates.

[0005] Through the above technical solution, the cover is rotatably connected to the two side walls of the box. When the cover is opened, the reel is easily removed from between the two snap-fit ​​seats, thereby facilitating the replacement of the advertising cloth in the box. When the cover is closed, the reel can be protected, and the pattern part of the advertising cloth is located between the two cover plates, which is convenient for displaying the advertisement on the advertising cloth.

[0006] Furthermore, the front edges of both side walls of the box body are fixedly provided with connecting parts which are perpendicular to the side walls of the box body and located inside the box body, the inner sides of the connecting parts are fixedly provided with limiting parts which are perpendicular to the connecting parts and extend away from the rear side walls of the box body, the limiting parts are fixedly provided with hinge seats which are perpendicular to the limiting parts and extend outward, the cover plate is bent toward the connecting parts to form a hinge portion, the hinge portion is perpendicular to the cover plate, the hinge portion is rotatably connected to the hinge seat, and the side edge of the limiting part away from the box body can abut against the inner side surface of the cover plate.

[0007] Through the above technical solution, the limiting portion abuts against the inner side surface of the cover plate to support the cover plate and limit the rotation angle of the cover plate at the same time.

[0008] Furthermore, both side walls of the box body are fixedly provided with a fixing portion which is perpendicular to the side walls of the box body and located inside the box body, and the inner edge of the fixing portion is fixedly provided with a supporting portion which is perpendicular to the fixing portion and extends away from the rear side wall of the box body, and the distance between one side edge of the supporting portion away from the rear side wall of the box body and the rear side wall of the box body is greater than the distance between the winding shaft and the rear side wall of the box body, and one side edge of the supporting portion away from the rear side wall of the box body abuts against the advertising cloth.

[0009] Through the above technical solution, the support part is used to support the advertising cloth, so that the advertising cloth can fit the inner side of the cover plate, reducing the gap between the advertising cloth and the cover plate.

[0010] Furthermore, one side edge of the cover plate away from the side wall of the box body is recessed toward the direction close to the rear wall of the box body to form a pressing portion, and the tangent direction of the one side edge of the pressing portion away from the side wall of the box body is parallel to the cover plate. When the cover plate is parallel to the box body, the distance between the one side edge of the pressing portion away from the side wall of the box body and the rear wall of the box body is smaller than the distance between the one side edge of the support portion away from the rear wall of the box body and the rear wall of the box body.

[0011] Through the above technical solution, when the cover is closed, the pressing part presses the advertising cloth toward the rear side wall of the box body, so that the advertising cloth can be tightened and flattened, thereby improving the display effect of the advertisement.

[0012] Furthermore, a reinforcing plate is fixed between the fixing portion and the rear side wall of the box body.

[0013] Through the above technical solution, the support strength of the support part is increased due to the support of the reinforcement plate.

[0015] Through the above technical solution, under the elastic force of the spring, the clamping block can be tightly clamped in the clamping hole, thereby achieving a fixed connection between the winding shaft and the clamping seat, and also facilitating the disassembly of the winding shaft and the clamping seat.

[0016] Furthermore, the advertising cloth can be rolled up on the outer periphery of a rolling shaft.

[0017] The above technical solution is helpful for storing the advertising cloth.

[0018] Furthermore, a limiting groove is provided on a side of the box plate close to the cover plate, a limiting plate is embedded in the limiting groove, and left and right ends of the limiting plate can abut against a side of the pressing part away from the box body.

[0019] Through the above technical solution, the two ends of the limiting plate abut against the pressing part, which can limit the rotation of the pressing part and keep the pressing part pressing the advertising cloth.

[0020] Furthermore, a side of the limit plate parallel to the rear side wall of the box body is provided with a plurality of connection holes extending in a direction perpendicular to the limit plate, and a side of the box plate parallel to the rear side wall of the box body is provided with a plurality of through holes connected to the limit grooves, the through holes correspond one to one to the connection holes, and a limit pin extending through the through holes is embedded in the connection holes.

[0021] Through the above technical solution, the limiting pin is inserted into the connecting hole and the through hole on the box body, so that the limiting plate can be fixed in the limiting groove.

[0022] Furthermore, a plurality of lamp tubes equidistantly distributed vertically are fixed in the box.
