Figure 1 As shown, pushing the handle 203 can push the support plate 202 to lift up inside the rear door 201 of the device;

[0031] The device body 1 includes a support frame 102, and support legs 101 are fixedly installed around the bottom of the support frame 102. The bottom of the support frame 102 and the middle of the support legs 101 are fixedly installed with a motor 106. A pulley 107 is fixedly installed at the output end of the motor 106. The outer wall of the pulley 107 is movably connected to a belt 109. The middle outer wall of the belt 109 passes through the support frame 102, and the inner wall of the end of the belt 109 away from the pulley 107 is movably connected to a pulley 2 108. Figure 1-2 As shown, when the motor 106 is started, the output end of the motor 106 drives the pulley 1 107 to rotate, and then drives the belt 109 to rotate so that the pulley 2 108 rotates;

[0032] The middle part of the outer wall of the second pulley 108 is rotatably connected to the support frame 102, one end of the middle part of the second pulley 108 passes through the support frame 102 and is fixedly installed with a driving gear 110, and the top of the outer wall of the driving gear 110 is meshed and connected with the driven gear 206, as shown in FIG. Figure 2 As shown, when the pulley 2 108 rotates, it drives the driving gear 110 to rotate, thereby driving the driven gear 206 to rotate;

[0033] A block 105 is slidably connected to the top inner wall of the support frame 102 and located above the push shaft 204. The block 105 is located on a side away from the rotating roller 205 and is provided with an inclined surface. The bottom of the block 105 passes through the device rear door 201 and the outer side wall is slidably connected to the device rear door 201. The bottom of the block 105 is movably connected to the push shaft 204. The top of the block 105 is fixedly connected to a spring 104. The top of the spring 104 is fixedly connected to the inner wall of the support frame 102. Figure 2As shown, when the device rear door 201 is closed, the top of the device rear door 201 contacts the inclined surface of the block 105, and then the block 105 is subjected to an upward force, so that the block 105 compresses the spring 104 and shrinks into the interior of the limit frame 102;

[0034] The outer wall of the support plate 202 and the end located away from the driven gear 206 are slidably connected with a movable clamping plate 208, and the two ends of the inner wall of the movable clamping plate 208 are respectively rotatably connected to the rotating rollers 205 on different sides. The bottom of the movable clamping plate 208 located on the side away from the rotating roller 205 is fixedly connected with a spring 209, and the other end of the spring 209 is fixedly connected to the support plate 202. Figure 5 As shown, the spring 209 pushes the movable clamping plate 208 to return to its original position and engage with the rotating roller 205;

[0036] The working principle of this utility model:

[0037] When it is necessary to replace the billboard in the device, first push the handle 203 upward to drive the support plate 202 to move upward, at which time the driven gear 206 is lifted up and separated from the driving gear 110 at the bottom. In addition, the push shaft 204 at the top of the support plate 202 contacts and pushes up the block 105, and the block 105 is lifted up and completely retracted into the interior of the support frame 102. At this time, the spring 104 connected to the block 105 is retracted. When the block 105 is lifted up and separated from the device rear door 201, the handle 203 can be pushed to drive the device rear door 201 to flip open. At this time, the spring 104 releases its elastic potential energy to push the lower block 105 to reset, and then the device back door 201 can be turned 90 degrees, and the movable clamping plate 208 is pushed to the side away from the driven gear 206, and the movable clamping plate 208 is separated from the rotating roller 205, and the spring 209 contracts. At this time, the billboard 207 can be pulled out and separated from the rotating roller 205. After the rotating rollers 205 on both sides are covered with new billboards, the movable clamping plate 208 is released, and the spring 209 releases its elastic potential energy to push the movable clamping plate 208 to reconnect with the rotating roller 205;

[0038] Secondly, after the billboard is replaced, the handle 203 is pushed to make the device rear door 201 flip and reset. When one side of the inclined surface of the block 105 contacts the device rear door 201, the block 105 is pushed upward and retracts into the interior of the support frame 102 again. When the device rear door 201 is completely closed, the spring 104 pushes the block 105 to move down and re-engage with the device rear door 201. At this time, the handle 203 is released, the support plate 202 falls, and the driven gear 206 re-engages with the driving gear 110. At this time, the starting motor 106 can drive the driving gear 110 to rotate through the belt, and then the rotating roller 205 at the bottom rotates and drives the billboard 207 to rotate and turn the pages.

[0039] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
