a billboard protection plate is shown in figure 1 and comprises a protection plate body 1, wherein two opposite side walls of the protection plate body 1 are provided with limiting sliding grooves 101, and the protection plate body 1 is detachably connected with a mounting mechanism. Installation mechanism holds box 3 and is used for placing advertising paper 6 including holding box 3, slide bar 2 and drive assembly, holds box 3 and is provided with intercommunication groove 301 on holding box 3, and intercommunication groove 301 is used for supplying advertising paper 6 to wear out, is formed with connecting portion 201 on the both ends of slide bar 2 respectively, connecting portion 201 and spacing spout 101 sliding fit. The accommodating box 3 and the sliding rod 2 are integrally arranged, the sliding rod 2 is provided with a squeezing part 203, the squeezing part 203 is used for squeezing the advertising paper 6 so as to enable the advertising paper 6 to be attached to the protection plate body 1, and the driving component is used for driving the sliding rod 2 and the protection plate body 1.

As shown in fig. 1 and 2, the driving assembly includes a mounting bracket 4, a wire winding roller 41 and a pulley 42. Installing support 4 can be dismantled with backplate body 1 and be connected, sliding connection has grip block 43 on installing support 4, be formed with the centre gripping space that is used for with backplate body 1 looks adaptation between installing support 4 and the grip block 43, it is connected with actuating lever 44 to rotate on installing support 4, grip block 43 and actuating lever 44 threaded connection, when actuating lever 44 rotates, actuating lever 44 drives grip block 43 and removes so that the volume in centre gripping space reduces, thereby make installing support 4 can be fixed on backplate body 1 or dismantle from backplate body 1. Wire winding roller 41 rotates and installs on installing support 4, and the winding has first connecting rope 412 on the wire winding roller 41, and the one end of first connecting rope 412 is stretched out by wire winding roller 41 and is used for providing the gliding drive power of messenger's it for backplate body 1 to slide bar 2, and fixedly connected with is used for driving wire winding roller 41 pivoted handle 411 on the wire winding roller 41. The pulley 42 is rotatably installed on the installation bracket 4, an axis of the pulley 42 is coaxially arranged with an axis of the winding roller 41, and the pulley 42 is used for the first connecting rope 412 to pass around to change a moving direction of the first connecting rope 412. The pulley 42 is disposed on the front side of the protecting plate body 1, specifically, on the side for mounting the advertisement paper 6, and the winding roller 41 is disposed on the rear side of the protecting plate body 1, which is mainly due to the fact that the supporting structure and the mounting structure are disposed on the rear side of the protecting plate body 1, so that the operator can stand and operate the protecting plate conveniently.

As shown in fig. 3, the sliding rod 2 includes a first sliding section 21 and two second sliding sections 22, each second sliding section 22 is slidably connected to one end of the first sliding section 21, an elastic member 23 is disposed between each second sliding section 22 and the first sliding section 21, and the elastic member 23 is used for providing an elastic force for making each second sliding section 22 approach each other. The elastic member 23 is provided as an extension spring. Fixedly connected with connecting rod 5 on slide bar 2 is formed with the clearance that is used for holding advertising paper 6 and passes between connecting rod 5 and the slide bar 2, and connecting rod 5 sets up to telescopic rod structure so that connecting rod 5 can be synchronous flexible with slide bar 2, and rope 413 is connected to fixedly connected with second respectively on the both ends of connecting rod 5, and the other end and the first connecting rope 412 fixed connection of second connecting rope 413. Make slide bar 2 can the not backplate body 1 of co-altitude of adaptation through above-mentioned setting, in order to reduce friction between connecting portion 201 and the spacing spout 101, rotate on the connecting portion 201 and be connected with gyro wheel 202, gyro wheel 202 offsets with the bottom surface of spacing spout 101. The two adjacent side surfaces of the sliding rod 2 are smoothly transited to form a transition surface 204, and the transition surface 204 is used for sliding relative to the advertising paper 6.

The specific implementation mode of the scheme is as follows:

during the use, earlier install installing support 4, rotatory actuating lever 44 makes keeping away from each other between grip block 43 and the installing support 4, and then reverse rotation actuating lever 44 makes and is close to each other between grip block 43 and the installing support 4 for installing support 4 is by the centre gripping on backplate body 1, then installs slide bar 2 to on the opposite side of backplate body 1. One side of the advertisement paper 6 extends out of the containing box 3 and is fixed on the protection plate body 1, and then two second sliding sections 22 are pulled towards the directions away from each other, so that the length of the sliding rod 2 is extended, meanwhile, the length of the connecting rod 5 is synchronously extended, and the two sliding parts are respectively installed in the corresponding limiting sliding grooves 101. At this time, the pressing portion 203 of the sliding rod 2 presses the advertisement paper 6 so that the advertisement paper 6 and the cover plate body 1 are attached to each other. Then rotate winding roller 41 and make the length of first connecting rope 412 shorten gradually, second connecting rope 413 drives slide bar 2 and removes to the direction that is close to winding roller 41, and extrusion portion 203 continues extrusion advertising paper 6 and backplate body 1 at the in-process that removes for advertising paper 6 is shakeout on backplate body 1, and advertising paper 6 is owing to receive the extrusion of slide bar 2 simultaneously, continuously stretches out in accomodating box 3. And after the flattening is finished, the sliding rod 2 and the driving component are removed.
