When the first extending column 11 extends, the second extending column 12 retracts, and the adjusting column 15 slides towards the second extending column 12, at this time, the first cloth rod 21 and the horizontal rod 24 support the first background cloth, and the second background cloth retracts behind the first background cloth under the driving of the second cloth rod 22; on the contrary, when the second extending column 12 extends and the first extending column 11 retracts, the adjusting column 15 slides towards the first extending column 11, at this time, the second cloth rod 22 and the horizontal rod 24 support the second background cloth, and the first background cloth retracts to the rear of the second background cloth under the driving of the first cloth rod 21.

It should be noted that, to select the turning roller 14 with a suitable diameter, it is ensured that the turning roller 14 rotates half a turn, and just completes the route of the first extending column 11 retracting from the extending direction to the retracting direction, and the turning roller 14 rotates half a turn, and the adjusting column 15 just shifts from one side of the turning roller 14 to the other side, of course, it is required to ensure that the length of the adjusting column 15 is just the same as the length of the first extending column 11 or the second extending column 12 when extending, so that one of the colors of the background cloth 23 is just parallel to the outside when extending.

Only need drive live-rollers 14 rotate half a circle can, the background cloth 23 returns and correspondingly transmits on horizontal rod 24, can accomplish the switching between the background cloth of two colours like this, need not to go up and down the background cloth, and the background cloth also is difficult for blocking, switches convenient quick.

The utility model relates to a dual stage background cloth device convenient to switch's simple structure, the background cloth of two colours can switch at any time, and switching speed is fast, is difficult for the card cloth, and stability is high, and need not to carry out lifting control.

Embodiment two, still as shown in fig. 1 to 3, only do one of them embodiment of the utility model, in order to make the utility model relates to a switching effect of double stage background cloth device convenient to switch is better, and stability is higher, the utility model discloses in still have following design:

first, the extending direction of the passing groove 16 is perpendicular to the horizontal rod 24, so that when the adjusting column 15 slides in the passing groove 16, the horizontal rod 24 slides perpendicularly to the direction of the first cloth rod 21 or the second cloth rod 22.

And at least a part of the horizontal bar 24 is arc-shaped, which is convenient for the horizontal bar 24 to slide on the back surface of the background cloth 23 when sliding.

Of course, the first cloth bar 21 and the second cloth bar 22 are both provided with buckles 211 for clamping the background cloth 23, and the two sides of the background cloth 23 are buckled from two directions, so that the background cloth 23 is kept in a tensioned state. The background cloth 23 can also be replaced by the clip 211.

In order to guarantee that the regulation post 15 is perpendicular to all the time and adjusts the chamber 1 surface, be provided with the locating part 17 on the groove 16, the locating part 17 including set up in adjust first spacing post 171 in the chamber 1, set up in adjust the spacing post 172 of the outer spacing post 172 of second in chamber 1 and be used for connecting the spliced pole 173 of first spacing post 171 and the spacing post 172 of second, be provided with on the locating part 17 and be used for the convenience adjust the through-hole 174 that the post 15 passed, moreover through-hole 174 extending direction with set up perpendicularly through groove 16. Here, the outer diameter of the connecting post 173 is just the same as the through groove 16, the length of the connecting post 173 is just the same as the thickness of the through groove 16, the inner diameter of the through hole 174 is the same as the outer diameter of the adjusting post 15, that is, the first limiting post 171 and the second limiting post 172 are just clamped on both sides of the through groove 16, and the adjusting post 15 passes through the through hole 174 of the limiting member 17 and passes through the through groove 16. In effect, the limiting member 17 slides left and right in the through slot 16, and the adjusting post 15 extends and retracts in the through hole 174 of the limiting member 17.

The adjusting column 15 rotates around the joint with the rotating roller 14, so that the adjusting column 15 is ensured to extend out of the joint with the rotating roller 14 forever and extend out of the adjusting cavity 1 perpendicular to the surface of the adjusting cavity 1.

In order to facilitate the left-right sliding of the limiting member 17 in the through groove 16 and the front-back expansion of the adjusting column 15 in the through hole 174 of the limiting member 17, a lubricating layer is arranged on the inner side of the through groove 16 and the inner side of the through hole 174, so that the sliding is facilitated.

Moreover, the number of the through grooves 16 and the number of the adjusting columns 15 are at least one, two or more adjusting columns 15 are connected to one horizontal rod 24, so that the horizontal rod 24 and the first cloth rod 21 can be arranged in parallel, each adjusting column 15 is provided with one through groove 16, the two adjusting columns 15 can be arranged at two ends of the rotating roller 14, and the two through grooves 16 are arranged in parallel.

Similarly, the number of the first extending columns 11 and the second extending columns 12 is at least one, two or more first extending columns 11 should be connected to one first cloth rod 21, and two or more second extending columns 12 should be connected to one second cloth rod 22.

Finally, in order to facilitate the extension and retraction of the first extending column 11, a first limiting block 111 is arranged at one end of the first extending column 11 close to the pull rope 13, and a first limiting spring 112 sleeved on the outer side of the first extending column 11 is arranged between the first limiting block 111 and the inner side wall of the adjusting cavity 1. The pull cord 13 can pull back the first projecting stud 11 to retract into the adjustment chamber 1, but when the pull cord 13 pulls back the second projecting stud 12, the first projecting stud 11 is released, and at this time the first projecting stud 11 projects out of the adjustment chamber 1 under the restoring tension of the first limiting spring 112.

Similarly, a second limiting block 121 is arranged at one end of the second extending column 12 close to the pull rope 13, and a second limiting spring 122 sleeved outside the second extending column 12 is arranged between the second limiting block 121 and the inner side wall of the adjusting cavity 1.

The present invention is not limited to the above-described specific embodiments, and various modifications and changes are possible. Any modification, equivalent replacement, improvement and the like made to the above embodiments according to the technical spirit of the present invention should be included in the scope of protection of the present invention.
