Embodiment

[0024] Example: such as figure 1 and figure 2 As shown, the multi-picture winding device includes a frame 1, and two rotating shafts fixed in the frame 1 for winding the picture 2 are arranged parallel to each other, that is, the first rotating shaft 3 and the second rotating shaft 4. It is characterized in that the frame 1 is also provided with at least one transmission shaft 5. The transmission shaft 5 is located between the first rotating shaft 3 and the second rotating shaft 4, and is arranged perpendicular to the two rotating shafts. Wheel 5a and shaft two driving wheels 5b are provided with shaft one gear 3a that can be meshed with shaft one driving wheel 5a on rotating shaft one 3, and are provided with shaft two that can mesh with shaft two driving wheels 5b on rotating shaft two 4. Gear 4a, above-mentioned shaft-drive wheel 5a can rotate by driving clutch device-drive shaft-gear 3a, and above-mentioned shaft two drive wheels 5b can rotate by driving clutch device-dr...

Embodiment 2

[0038] Embodiment 2: as Figure 4 As shown, in this embodiment, the shaft-1 drive wheel 5a and the shaft-2 drive wheel 5b at both ends of the transmission shaft 5 are fixed together. Shaft 1 driving wheel 5a can be engaged with or disengaged from shaft 1 gear 3a through driving clutch device 1; shaft 2 driving wheel 5b can be meshed with or disengaged from shaft 2 gear 4a through driving clutch device 2. When the transmission shaft 5 swings left and right, the drive of different rotating shafts is realized, and the rest are similar to those in Embodiment 1, which will not be repeated here.

Embodiment 3

[0039] Embodiment 3: as Figure 5 As shown, in this embodiment, one side of the rotating shaft is provided with a picture-changing wheel 35 close to it, and the picture-changing wheel 35 is fixedly connected with a gear 36, and the gear 36 is meshed with an electric control gear 37 , the central axis of the electric control gear 37 is connected with a fulcrum 38, the fulcrum 38 is connected with the movable contact 39, the movable contact 39 can be connected with the fixed contact 40, and the fixed contact 40 and the movable The contacts 39 are connected to a power source 42 through a control switch 41 . The picture-changing wheel 35 leans against the rotating shaft-3, and the rotating shaft-3 can drive the picture-changing wheel 35 to rotate. Simultaneously, the gear 36 also rotates thereupon, and the fulcrum piece 38 is driven by the electric control gear 37 to move. The fulcrum piece 38 can drive the movable contact 39 to separate the movable contact 39 from the fixed con...

Abstract

The present invention relates to one kind of multiple picture winding set in improved structure. The multiple picture winding set includes one frame, two parallel rolling shafts set inside the frame for winding pictures, one driving shaft capable of swinging and connected with one of the rolling shafts, and one electrically and / or manually driving mechanism. The present invention has the following advantages: smooth driving, smart reversing mechanism, stable operation, capacity of changing different pictures, etc.

Description

technical field [0001] The present invention relates to a device for accommodating a picture frame of a picture or a picture, in particular to a structural improvement of a multi-picture rolling device. The device is also applicable to various craft paintings, calendars, advertising frames and other application occasions. Background technique [0002] In order to realize the automatic switching of multiple pictures, people have carried out long-term exploration and put forward various implementation schemes. Among them, some have been widely applied to occasions such as picture frames with multi-screen automatic flipping, advertising boxes with replaceable screens, and background replacement devices in photo studios. For example, someone has improved the picture frame by adopting many triangular planks to rotate, but this scheme can only be increased to three pictures, and the number of pictures is limited. The background paintings in the photo studio and the map wall char...
