[0026] In use, the support frame two 9 is first turned out of the receiving groove one of the mounting plate 1, so that the support frame two 9 cooperates with the support frame one 8 fixedly installed at the bottom of the mounting plate 1 to form stable support, and then the two groups of folding assemblies are started, the folding assemblies drive the two groups of bearing assemblies to gradually unfold along the two sides of the mounting groove and assume a folded arc shape, and in this unfolding process, the sliding action of the bearing assembly synchronously triggers the lighting assembly, so that the lighting assembly is gradually turned on and forms lighting for the bearing assembly; after use, the support frame two 9 is locked and fixed by the two groups of locking assemblies, thereby realizing automatic adjustment of the unfolding angle of the placing plate according to the length of the poster, adapting to display of posters of different lengths, and ensuring that the audience can clearly see all the displayed content without moving positions, and the operation is convenient.

[0027] Further, reference is made to Figures 1-3 , Figure 6 and Figure 7The bearing assembly comprises a storage plate 201, two ends of the storage plate 201 are respectively slidably installed on the two sides of the inner wall of one end of the mounting groove through the sliding assembly, the middle position of the inner wall of one end of the mounting groove is fixedly installed with a storage plate 2 202, the folding assembly comprises a mounting groove plate 203, a sleeve 1 204 and a plug rod 205, the mounting groove plate 203 is fixedly installed on one side of the mounting plate 1, the two sides of one end of the circumferential outer wall of the sleeve 1 204 are respectively rotatably installed on the top inner wall and the bottom inner wall of the mounting groove plate 203, one end of the plug rod 205 is inserted into the sleeve 1 204, the other end of the plug rod 205 is hingedly connected to one end of one of the storage plate 1 201 away from the storage plate 2 202, and the two sides of one end of the mounting plate 1 are fixedly installed with limit blocks 206, and the side close to the sleeve 1 204 of the limit block 206 is arranged in an inwardly recessed arc shape.

[0028] In the initial state, the sleeve 1 204 is in a nearly vertical state with the storage plate 1 201, and in operation, the sliding assembly is started first to drive the two storage plate 1 201 to slide away from each other along the two sides of the inner wall of one end of the mounting groove, in this process, the storage plate 1 201 will pull the plug rod 205 hingedly connected thereto, so that the plug rod 205 is gradually pulled out of the sleeve 1 204, at the same time, the sleeve 1 204 will rotate around the top inner wall and the bottom inner wall of the mounting groove plate 203, when the sleeve 1 204 is rotated to an appropriate inclined position, it will be in contact with the limit blocks 206 on the two sides of one end of the mounting plate 1, and the inwardly recessed arc structure on the side close to the sleeve 1 204 of the limit block 206 is used to limit the rotation of the sleeve 1 204, and the two storage plate 1 201 are moved by the sliding assembly, at this time, the inclination angle of the storage plate 1 201 will be greatly increased than before, and the design of the angle can avoid the problem that the length of the subsequently pasted advertising paper, poster and other materials is too long, so that the content on the two sides is difficult to observe or appears to be not clear due to reflection, according to the length of the advertising paper, poster to be pasted, the two storage plate 1 201 are moved to an appropriate distance and then stopped, and then the left end of the advertising paper or poster is pasted or hung on one of the storage plate 1 201, the right end is pasted or hung on the other storage plate 1 201, and the middle part is pasted or hung on the storage plate 2 202 on the middle position of the inner wall of the mounting groove, so that the material forms a three-folded arc state with three supporting points, in this state, the text content on the poster can face the viewer, and the viewer does not need to move the position, but only needs to turn the head to clearly see all the material content on the two storage plate 1 201 and the storage plate 2 202, effectively avoiding the problem of unclear viewing due to reflection, realizing automatic adjustment of the opening angle of the storage plate 1 201 according to the length of the poster, adapting to the display of posters of different lengths, ensuring that the audience can clearly see all the displayed content without moving the position, and the operation is convenient.

[0029] Further, referring to Figure 1 and Figure 2The middle position of the top of one end of the mounting plate 1 is provided with a placing groove, and the top of the inner wall of the two ends of the placing groove is hingedly connected with a hanging plate 301, the top of one end of the hanging plate 301 is provided with a hooking opening, the bottom of the inner wall of one end of the placing groove is fixedly installed with a clamping block 302, the clamping block 302 is matched with the hooking opening, and the two sides of one end of the supporting frame 8 are provided with receiving grooves two, and the two receiving grooves one are respectively and communicatively arranged with the two receiving grooves two.

[0030] In the initial state, the hanging plate 301 is accommodated in the placing groove in the middle of the top of one end of the mounting plate 1, and the hooking opening in the top of the hanging plate 301 is clamped and fixed with the clamping block 302 in the bottom of the inner wall of the placing groove, and the supporting frame two 9 is accommodated in the receiving groove one of the mounting plate 1 and the receiving groove two of the supporting frame one 8 in communication, in use, first rotate the hanging plate 301 outward to make the hooking opening disengage from the clamping of the clamping block 302, then rotate the hanging plate 301 out of the placing groove, and then rotate the supporting frame two 9 out of the receiving groove one and the receiving groove two in communication, and then stand the supporting frame two 9 on the ground, and then cooperate with the supporting frame one 8 to realize the inclined support and display of the mounting plate 1, when not in use, first fold the supporting frame two 9 back into the receiving groove one and the receiving groove two, then rotate the hanging plate 301 back to the placing groove, and then make the clamping block 302 re-enter the hooking opening to complete the fixing, or the whole device can be hung on the connecting rod or other preset positions through the hooking opening of the hanging plate 301, and a plurality of the billboards can be sequentially arranged and hung through the hanging plate 301 to realize neat storage.

[0031] Further, referring to Figure 1 and Figure 7 The sliding assembly comprises two electric sliding rails 401 and two electric sliding blocks 402, the two electric sliding rails 401 are fixedly installed on the top and the bottom of one side of the inner wall of one end of the mounting groove, the two electric sliding blocks 402 are slidingly installed on the two electric sliding rails 401, and the two electric sliding blocks 402 are hingedly connected with the top and the bottom of the other side of the end of the object plate one 201 close to the mounting plate 1; the lighting assembly comprises a plurality of lighting lamps one 501 and a plurality of lighting lamps two 502, the plurality of lighting lamps one 501 are arranged and fixedly installed on the middle position of the top inner wall of the mounting groove, the two object plates one 201 are provided with object grooves at the end away from the mounting plate 1, the plurality of lighting lamps two 502 are arranged and fixedly installed on the top inner wall of the two object grooves, and the two sides of the top inner wall of one end of the mounting groove are arranged and fixedly installed with trigger switches 503, the top of the two electric sliding blocks 402 close to the trigger switches 503 in the two groups is fixedly installed with trigger blocks 504, and the plurality of trigger switches 503 are electrically connected with the plurality of lighting lamps two 502.

[0032] In the initial state, the electric sliding block 402 is in the initial proximal position of the electric sliding rail 401, the trigger block 504 at the top of the electric sliding block 402 is not in contact with the trigger switch 503 on the top of the inner wall of one end of the mounting groove, at this time only a plurality of lighting lamps 1 501 in the middle of the top inner wall of the mounting groove are turned on, which can meet the basic lighting needs of short and wide posters, avoid waste caused by excessive light sources, and operate to start the sliding assembly. The two electric sliding blocks 402 will slide horizontally away from the display plate 2 202 along the corresponding electric sliding rail 401, since the electric sliding block 402 is hinged to the display plate 1 201 near one end of the mounting plate 1, the sliding of the electric sliding block 402 will synchronously drive the two display plates 1 201 to expand to both sides. In this process, the trigger block 504 at the top of the electric sliding block 402 will move synchronously with the electric sliding block 402, and then sequentially contact the trigger switches 503 arranged on both sides of the top of the mounting groove. Since the trigger switches 503 are electrically connected with a plurality of lighting lamps 2 502 in the display groove of the display plate 1 201, each time a trigger switch 503 is triggered, a plurality of lighting lamps 2 502 will be started. As the electric sliding block 402 continues to move, the expansion width of the display plate 1 201 gradually increases to adapt to wider posters, and the folding angle also increases. At this time, only the lighting lamps 1 501 cannot cover the area on both sides, and the problem of reflection and unclearness is prone to occur after the folding angle increases. The lighting lamps 2 502 that are turned on one by one can accurately illuminate the content of the poster on the display plate 1 201, realizing the adaptive effect that the larger the width of the poster and the folding angle, the more the number of lighting lamps 2 502 turned on. It ensures that the full-width poster is clear and visible, and avoids waste of light sources.

[0033] Further, with reference to Figure 4 、 Figure 5 and Figure 8 , the locking assembly comprises: two sleeve 2 601, two plug blocks 602, two locking blocks 603 and two buffer springs 604. Two sleeve 2 601 are fixedly installed at the bottom of both sides of the support frame 2 9, two plug blocks 602 are respectively inserted into two sleeve 2 601, two storage grooves 2 are respectively provided with a storage groove 3 on the bottom of the side away from each other, two locking blocks 603 are respectively fixedly installed on the inner wall of one end of two storage grooves 3 away from each other, two locking blocks 603 are respectively provided with a slot on the side away from each other, and the edges of the side of the two locking blocks 603 away from the support frame 1 8 are respectively provided with a smooth curved surface. The buffer spring 604 is fixedly installed between the inner wall of one end of the sleeve 2 601 and the plug block 602.

[0034] In the initial state, the support frame two 9 is accommodated in the accommodation groove one of the mounting plate 1 and the accommodation groove two of the support frame one 8, the plug block 602 is inserted in the sleeve two 601, and the buffer spring 604 between the inner wall of the sleeve two 601 and the plug block 602 is in a natural extension state. When locking operation is performed, the support frame two 9 is rotated to be turned out of the accommodation groove and expanded to support the ground. In this process, the sleeve two 601 fixed at the bottom of the two sides of the support frame two 9 is synchronously rotated with the support frame two 9, thereby driving the plug block 602 to gradually approach the locking block 603 in the accommodation groove three, and finally the plug block 602 contacts with the smooth curved edge away from one end of the support frame one 8. Since the edge is designed as a smooth curved surface, the plug block 602 is guided to be compressed to the inside of the sleeve two 601, and the buffer spring 604 in the sleeve two 601 is compressed at the same time. When the support frame two 9 is continuously rotated to a preset support angle, the plug block 602 is just aligned with the insertion slot on the locking block 603. At this time, the buffer spring 604 releases the elastic potential energy to push the plug block 602 into the insertion slot, thereby completing the locking and fixing of the support frame two 9 and the support frame one 8. Since the insertion slot is shallow and the plug block 602 protrudes little, the support stability of the support frame two 9 is not affected. When unlocking and accommodating is needed, the support frame two 9 is manually forced to be bent to synchronously move the sleeve two 601 and the plug block 602. The plug block 602 contacts with the side edge of the insertion slot, the side edge force pushes the plug block 602 to compress the buffer spring 604 and move to the sleeve two 601 again until the plug block 602 is completely separated from the insertion slot. At this time, the unlocking is completed, and the support frame two 9 can be folded and accommodated in the accommodation groove one and the accommodation groove two. The plug block 602 maintains the insertion state with the insertion slot under the action of the buffer spring 604 without automatic unlocking, thereby ensuring the stability during supporting.

[0035] Further, referring to Figure 1 and Figure 7 , the two sides of the inner wall of the top of the mounting groove are fixedly installed with limit plates 701 close to one end of the object plate one 201. The sides away from each other of the two limit plates 701 are arc-shapedly arranged away from the mounting plate 1.

[0036] In the initial state, the limiting plates 701 fixedly installed on the two sides of the inner wall of the top of the installation groove and close to one end of the placing plate one 201 form initial limiting on the two placing plate ones 201. When operating, the sliding assembly drives the two placing plate ones 201 to slide horizontally along the electric sliding rail 401 to the two sides. In this process, the placing plate one 201 will not be inclined at a large angle due to the blocking and limiting effect of the limiting plates 701. This is because the width of the poster adapted initially is small, and it is not necessary to change the inclination angle of the placing plate one 201 too early. It is only necessary to adjust the distance horizontally to meet the use requirement. With the sliding assembly continuously driving the placing plate one 201 to move outward, when the placing plate one 201 is about to be separated from the limiting plates 701, the width of the poster adapted at this time has gradually increased, and it is necessary to increase the inclination angle of the placing plate one 201 to ensure the viewing effect. The side of the limiting plates 701 away from each other is arc-shaped in the direction away from the mounting plate 1. The arc-shaped structure will play a smooth guiding role on the movement of the placing plate one 201, helping the placing plate one 201 to smoothly separate from the limiting plates 701. After being separated from the limiting of the limiting plates 701, the placing plate one 201 will begin to rotate at a large angle to adapt to the display requirement of the wide poster, so as to ensure that the poster content can be presented at a suitable inclination angle, avoiding the problem of reflection or unclear viewing.

[0037] Working principle: in the initial state, the hanging plate 301 is accommodated in the placing groove in the middle of the top of one end of the mounting plate 1, and the hooking opening in the top of the hanging plate 301 is clamped and fixed with the clamping block 302 in the inner wall of the bottom of the placing groove, the support frame two 9 is accommodated in the accommodation groove one of the mounting plate 1 and the accommodation groove two of the support frame one 8, the sleeve one 204 is in a nearly vertical state with the storage plate one 201, the electric sliding block 402 is in the initial proximal position of the electric sliding rail 401, the trigger block 504 in the top of the electric sliding block 402 is not in contact with the trigger switch 503 in the inner wall of the top of one end of the mounting groove, the buffer spring 604 between the inner wall of the sleeve two 601 and the plug block 602 is in a natural stretching state, the limiting plates 701 fixedly installed on both sides of the inner wall of the top of the mounting groove and close to one end of the storage plate one 201 will form initial limiting for the two storage plate one 201, in use, first rotate the hanging plate 301 outward, so that the hooking opening is separated from the clamping of the clamping block 302, and then the hanging plate 301 is rotated out of the placing groove, and then the support frame two 9 is rotated out of the accommodation groove one and the accommodation groove two, in the rotating process, the sleeve two 601 fixedly installed on both sides of the bottom of the support frame two 9 will rotate synchronously with the support frame two 9, thereby driving the plug block 602 to gradually approach the locking block 603 in the accommodation groove three, finally the plug block 602 contacts with the smooth curved edge of the locking block 603 away from one end of the support frame one 8, since the edge is designed as a smooth curved surface, it will have a guiding effect on the plug block 602, push the plug block 602 to compress into the sleeve two 601, at the same time, compress the buffer spring 604 in the sleeve two 601, continue to rotate the support frame two 9 to the preset support angle, the plug block 602 is just aligned with the plug slot on the locking block 603, at this time, the buffer spring 604 releases the elastic potential energy, pushes the plug block 602 into the plug slot, completes the locking and fixing of the support frame two 9 and the support frame one 8, then start the sliding assembly, the two electric sliding blocks 402 will slide horizontally away from the storage plate two 202 along the corresponding electric sliding rail 401, since the electric sliding block 402 is hinged to one end of the storage plate one 201 close to the mounting plate 1, the sliding of the electric sliding block 402 will synchronously drive the two storage plate one 201 to unfold to both sides, in this process, the storage plate one 201 will pull the plug rod 205 hinged thereto, so that the plug rod 205 is gradually pulled out of the sleeve one 204, at the same time, the sleeve one 204 will rotate around the top inner wall and the bottom inner wall of the mounting groove plate 203, and since the limiting plate 701 has a blocking limiting effect, the storage plate one 201 will not be inclined at a large angle, as the sliding assembly continues to drive the storage plate one 201 to move outward, when the storage plate one 201 is about to be separated from the limiting plate 701, the arc structure away from each other on one side of the limiting plate 701 will have a smooth guiding effect on the movement of the storage plate one 201, helping it to smoothly separate, after separation, the inclination angle of the storage plate one 201 will be greatly increased, when the sleeve one 204 is rotated to an appropriate inclined position, it will contact with the limiting block 206 on both sides of one end of the mounting plate 1, and be limited by the recessed arc structure close to the sleeve one 204 to prevent the sleeve one 204 from continuing to rotate, at the same time,The trigger block 504 at the top of the electric sliding block 402 moves synchronously with the electric sliding block 402, and then contacts the trigger switches 503 arranged on both sides of the top of the installation slot one by one. Since the trigger switches 503 are electrically connected with the lighting lamps two 502 in the installation slot of the installation plate one 201, each time a trigger switch 503 is triggered, a plurality of lighting lamps two 502 are started. In the initial state, only the lighting lamps one 501 in the middle of the inner wall of the top of the installation slot are turned on. As the electric sliding block 402 continues to move, the unfolded width of the installation plate one 201 gradually increases, and the folding angle also gradually increases. The lighting lamps two 502 turned on one by one can accurately illuminate the content of the poster on the installation plate one 201. According to the length of the advertising paper or poster to be posted, the two installation plate one 201 are moved to an appropriate distance and then stopped. Then the left end of the advertising paper or poster is pasted or hung on one of the installation plate one 201, the right end is pasted or hung on the other installation plate one 201, and the middle part is pasted or hung on the installation plate two 202, so that the material forms a three-folded arc state with three supporting points. In this state, the text content on the poster can face the viewer, and the viewer does not need to move position, but only needs to turn his head to clearly see all the material content on the two installation plate one 201 and the installation plate two 202, effectively avoiding the problem of unclear viewing caused by reflection. After use, the support frame two 9 is manually moved with force to drive the sleeve two 601 and the plug block 602 to move synchronously. The plug block 602 will contact the side of the insertion slot. The side force will again push the plug block 602 to compress the buffer spring 604 and move into the sleeve two 601 until the plug block 602 completely separates from the insertion slot. At this time, the unlocking is completed, the support frame two 9 can be folded and stored in the storage slot one and the storage slot two, and the hanging plate 301 is turned back to the placement slot to make the clamping block 302 re-clamp into the hooking opening to complete the fixation. The entire device can also be hung on the connecting rod or other predetermined position through the hooking opening of the hanging plate 301. A plurality of the advertising board can be hung and arranged in sequence through the hanging plate 301 to realize neat storage. The unfolded angle of the installation plate one 201 is automatically adjusted according to the length of the poster, different length posters are displayed, and the audience can clearly see all the displayed content without moving position. The operation is convenient.
