Abstract

The utility model relates to a flat-picture changing lamp box, which comprises an upper clamping plate, a lower clamping plate, two rollers arranged between the upper and lower clamping plates, two rotary wheels which drive the rollers to rotate back, a driving plate gear connected with a fan-shaped frame, two bridge wheels, five positioning levers, a positioning light plate, and a picture film which is wound on the two rollers to mutually rotate back and can change the flat picture. When in use, the driving plate gear is rotated to drive the bridge wheel and then drive the rotary wheel and the rollers to rotate back, to make the picture film move laterally left and right or move longitudinally up and down for flat display and changing pictures. As an advertising lamp box, the utility model has multiple purposes, and is economical and practical.

Description

Plane picture conversion lamp box

The utility model relates to advertising lamp box, the advertising lamp box of particularly a kind of convertible plane picture.

Existing advertising lamp box, its size difference, different, on lamp box flat glass or organic glass, paste the plastic sheeting picture, picture is used light-illuminating behind.Because picture is single, just need to change picture, if frequent dismounting, trouble very then, therefore this lamp box practicality is relatively poor, advertising results a little less than.

The purpose of this utility model provides a kind of improved plane picture conversion lamp box, and it can make the horizontal left and right displacement of the film with tens width of cloth pictures or change installation direction and be vertical upper and lower displacement and come the plane to show and the conversion picture.

A kind of plane picture conversion lamp box described in the utility model comprises a train wheel bridge, one lower plate, two cylinders that are vertically mounted on side by side between train wheel bridge and the lower plate, it also comprise two each below cylinder, install and drive the rotating rotor wheel of cylinder by rotating axle, one is installed on the lower plate by the dial gear shaft, be the dial gear of symmetrical triangle with two cylinders, one is coaxial mounted with the dial gear, respectively establish a semilune groove near place, arc fan limit in its support body two sides fan-shaped, two are positioned at that dial gear two sides are connected with the dial gearing mesh, both can in fan-shaped semilune groove, move, the idler that can be connected with a joggle with one of them rotor wheel also, can make the backstay of picture film around being arranged on two cylinders more than five around its rotation, one location-plate that is arranged on two cylinder the place aheads is together with light plate, and one is wound on two cylinders the picture film of rotating and convertible plane picture mutually.

Adopt the utility model as advertising lamp box, can reach the effect of using for a case more, economical and practical, lively.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a kind of main TV structure synoptic diagram of plane picture conversion lamp box.

Fig. 2 is the left view of above-mentioned lamp box.

Fig. 3 is the upward view of above-mentioned lamp box.

Fig. 4 is the connection diagram between above-mentioned lamp box intermediate roll, backstay and the picture film.

Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of plane picture conversion lamp box comprises 2, two cylinders 3 that are vertically mounted on side by side between train wheel bridge 1 and the lower plate 2 of a train wheel bridge 1, one lower plate.It comprises that also two each rotating axles of installing 4 that also pass through drive cylinders 3 rotating rotor wheels 5 below cylinder 3, one is installed on the lower plate 2 by dial gear shaft 6, be the dial gear 7 of symmetrical triangle with two cylinders 3, one is coaxial mounted with dial gear 7, respectively establish a semilune groove 8 near place, arc fan limit in its support body two sides fan-shaped 9, two are positioned at that dial gear 7 two sides and dial gear 7 be connected with a joggle, both can in fan-shaped 9 semilune groove 8, move, the idler 10 that can be connected with a joggle with one of them rotor wheel 5 also, can make the backstay 12 of picture film 11 around being arranged on two cylinders 3 more than five around its rotation, one location-plate 13 that is arranged on two cylinder 3 the place aheads is together with light plate 14, and one is wound on two cylinders 3 the picture film 11 of rotating and convertible plane picture mutually.

On train wheel bridge 1 and the lower plate 2 installation foot 15 is housed respectively, bracket foot 16 also is housed, on the lower plate 2 with the usefulness of the connection that fixes.Cylinder 3 tops are drum covers 17, and the bottom is a cylinder base 18.Screw 19 is fixedly connected with rotating axle 4 with

cylinder

3, and 20 on nut is fixedlyed connected dial gear 7 by dial gear shaft 6 with fan-shaped 9 with lower plate 2.Because idler 10 is connected with a joggle with dial gear 7, rotating driver plate gear 7 also drives idler 10, and then drives rotor wheel 5 and cylinder 3 revolutions.Shown in Figure 3, when dial gear 7 turns clockwise, drive idler 10 along moving down in fan-shaped the 9 semilune groove 8, drive rotor wheel 5 and cylinder 3 thus and turn round clockwise, 11 of picture films are to left dislocation; Vice versa.

On the light plate 14 of two cylinder 3 the place aheads settings luminescent device is housed, light plate 14 is the location plug-in type, by location-plate 13 location that are positioned on the train wheel bridge 1.Light plate 14 adopts plug-in type, is convenient to the maintenance of luminescent device.

Referring to Fig. 4, a central locating rod 21 in the backstay 12 is arranged on the back angle top between two cylinders 3, two

backstays

22,23 in other four backstays are separately positioned on the front left side of left side cylinder 3, and other two

backstays

24,25 are separately positioned on the forward right side of right side cylinder 3.22,32 and two left

side positioning rod

24,25 of two left positioner bars are set with and can drive the slip cap 26 that picture film 11 rotates, and 21 of backstays are not with slip cap.

Compound being equipped with of the inside surface of picture film 11 between left side first backstay 23 and right side first backstay 25 can make picture film 11 become the lining form 27 of light, as adopts blue lining form to become light.

The utility model not only can rotate the conversion picture by the manual dial of dial gear, and can adopt motor-driven, promptly installs or changes into belt pulley additional at manual dial place and drive.
