Utility Model Content

[0004] In view of the above-mentioned prior art, the present invention provides a foldable billboard, and the main technical problem to be solved is how to improve the stability of the billboard when it is erected and used outdoors.

[0005] To achieve the above purpose, the technical solution of the embodiment of the utility model is implemented as follows:

[0006] A foldable billboard comprises at least two folding boxes, which are rotatably connected in sequence. The inside of the folding boxes is provided with a billboard, a lifting mechanism and a locking mechanism. The lifting mechanism is used for displaying and storing the billboard. The lifting mechanism comprises a fixed frame, and the top ends of the inner walls on both sides of the fixed frame are rotatably connected with a rotating shaft. The billboard is located on the inner side of the fixed frame, and the billboard is fixedly connected to the rotating shaft. The locking mechanism is used to lock the fixed frame after it is lifted or lowered.

[0007] Furthermore, the rotating shaft is at three-quarters of the height of the billboard, and a notch is provided on one side of the rotating shaft body, a threaded through hole is provided on one side of the notch, and a bolt is threadedly connected to the threaded through hole of the rotating shaft, and the billboard is made of grating card.

[0013] The beneficial effects of the utility model are:

[0014] 1. When using this device, you can first open the two folding boxes and place them upright in a V shape, and then draw a fixed frame from the inside of the two boxes to make the billboard display. At this time, the two folding boxes can enhance the stability of the device by supporting each other. At the same time, since the billboard and the fixed frame are rotatably connected, the wind resistance of the device as a whole can be reduced. Therefore, this device can have more sufficient stability when used upright outdoors; secondly, since the billboard is rotatably connected to the fixed frame at three-quarters of its height, its center of gravity is lower, and when the external airflow blows the billboard, it can be deflected first and then restored. In this case, the billboard made of grating cards can make the advertising content appear dynamic, so the display effect of the billboard can be enhanced;

[0015] 2. By setting up elastic ropes and fixing clips, when external airflow blows onto the billboard to deflect it, the elastic rope can limit its swing range, preventing its large-angle swing from generating inertia and affecting the stability of the device, while also maintaining the dynamic effect of the grating card; secondly, the fixing clip made of stainless steel can not only connect the billboard with the elastic rope, but also act as a counterweight at the bottom of the billboard, thereby maintaining the stability of the center of gravity of the billboard and allowing it to return to its original state after deflection.

[0016] 3. By providing a sleeve, when the two folding boxes are buckled together, the sleeve can be put on the outside of the two fixing piles to maintain the folded state of the two folding boxes. In this case, the whole device can be integrated into the shape of a suitcase, so that the device can be conveniently carried and used. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example 1

[0026] Refer to the attached Figure 1-3 The present application provides a foldable billboard, comprising at least two folding boxes 1, which are rotatably connected in sequence. The number of folding boxes 1 can be multiple. For example, when the number is two, the two can be arranged in a V shape to enhance the stability of the upright placement. When the number is three or more, they can be arranged in an N shape and a W shape to maintain the stability of the placement of the device. The interior of the folding box 1 is provided with a billboard 7, a lifting mechanism and a locking mechanism. The lifting mechanism is used for displaying and storing the billboard 7. When the billboard 7 rises to be completely exposed to the outside world, the advertisement on its surface can be displayed, and when it is lowered to the inside of the folding box 1, It will be stored, the lifting mechanism includes a fixed frame 5, the top of the inner walls on both sides of the fixed frame 5 are rotatably connected with a rotating shaft 6, the billboard 7 is located on the inner side of the fixed frame 5, and the billboard 7 is fixedly connected to the rotating shaft 6, that is, the billboard 7 is rotatably connected to the inner side of the fixed frame 5 through the rotating shaft 6. In this case, the airflow blowing to the surface of the billboard 7 can pass through the fixed frame 5 smoothly after deflecting it, thereby reducing the wind resistance of the device, thereby further ensuring the stability of the device when it is used upright outdoors, and the locking mechanism is used to lock the fixed frame 5 after lifting, so as to ensure the stability of the billboard 7 in the two states of display after rising and storage after falling.

[0027] Preferably, the rotating shaft 6 is at three-quarters of the height of the billboard 7, so the center of gravity of the billboard 7 is biased downward, so it can still return to its original state after being swung by the airflow, and a notch is provided on one side of the shaft body of the rotating shaft 6, the notch is used to accommodate the billboard 7, and the width of the notch is consistent with the thickness of the billboard 7, and a threaded through hole is provided on one side of the notch of the rotating shaft 6, and a bolt 601 is threadedly connected to the threaded through hole of the rotating shaft 6, and the billboard 7 can be fixedly connected to the fixed frame 5 in a detachable manner through the bolt 601, so that the billboard 7 with different contents can be easily replaced, and the billboard 7 is made of grating card, so when the external airflow causes the billboard 7 to deflect, it can avoid showing different pictures, and then the picture displayed by the billboard 7 can produce a dynamic effect through artistic design, thereby increasing the attractiveness of the billboard 7. Elastic ropes 3 are fixedly connected to the bottom ends of the inner walls on both sides of the fixed frame 5. The elastic ropes 3 can limit the deflection range of the billboard 7 by pulling the billboard 7 to prevent excessive deflection. One end of the two elastic ropes 3 is fixedly connected to a fixing clamp 4. The two fixing clamps 4 are respectively clamped at the two sides of the bottom end of the billboard 7, and the material of the two fixing clamps 4 is stainless steel. The fixing clamps 4 made of stainless steel can detachably connect the elastic ropes 3 and the billboard 7, and can also add a counterweight at the bottom end of the billboard 7, so that the elastic force of the elastic ropes 3 can be used to make the billboard 7 quickly recover after deflection. The top of the fixed frame 5 is fixedly connected to a cover plate 8, which can close the folding box 1, thereby facilitating the storage of the billboard 7.

[0028] Preferably, baffles 13 are fixedly connected at the top ends of the inner walls on both sides of the folding box 1, and slide bars 10 are fixedly connected between the two baffles 13 and the inner walls of the bottom end of the folding box 1. The outsides of the two slide bars 10 are sleeved with slide sleeves 2, and the inner walls of the slide sleeves 2 and the outer walls of the slide bars 10 are smoothed. The baffles 13 can limit the maximum movement range of the slide sleeves 2, so as to prevent them from falling off the slide bars 10, thereby ensuring the stability of the fixed frame 5 and the billboard 7 inside it. The fixed frame 5 is fixedly connected between the two slide sleeves 2, and the two slide sleeves 2 are located at the bottom ends of both sides of the fixed frame 5. The locking mechanism includes four spring sheets 11, which are respectively fixedly connected to the top and bottom ends of the inner walls on both sides of the folding box 1, and one side of the four spring sheets 11 is fixedly connected with a card block 12. The two spring sheets 11 and the card block 12 at the top are used to maintain the display state of the fixed frame 5 after it is raised, and the two spring sheets 11 and the card block 12 at the bottom are used to maintain the storage state of the fixed frame 5 after it is lowered. A card slot is provided on one side of the two sliding sleeves 2. The two card blocks 12 and the card slots are both hemispherical, and the card block 12 is adapted to the card slot. When the hemispherical card block 12 contacts the spherical surface of the card slot, the spring sheet 11 can be overcome when a large force is applied, so that the card block 12 is disengaged from the card slot, thereby adjusting the lifting state of the fixed frame 5.

[0029] Preferably, the number of foldable boxes 1 is two. The two foldable boxes 1 can maintain the stability of the device by supporting each other, and will not be too heavy to be portable. The two foldable boxes 1 are rotatably connected by a damping shaft, and the damping shaft can maintain the states of the two before and after folding, so as to facilitate the shaping of the two. A handle 9 is fixedly connected to one side of the two foldable boxes 1. After the device is used, the two foldable boxes 1 can be folded so that the two are combined into a whole with an appearance similar to a suitcase. At this time, the handle 9 can be used to lift and carry the device.

[0030] Working principle: When using the device, the two folding boxes 1 can be opened and set upright in a V-shaped state at the target position, and then the cover plate 8 is pulled to drive the fixed frame 5 to rise, and the fixed frame 5 can drive the billboard 7 and the sliding sleeve 2 to rise at the same time. When the sliding sleeve 2 rises along the sliding rod 10 to the spring sheet 11 at the upper end, the spring sheet 11 can push the card block 12 into the card slot on the sliding sleeve 2, so that the sliding sleeve 2 can be fixed, and then the raised state of the fixed frame 5 is maintained, so that the billboard 7 can be exposed to the outside world;

[0031] After the above operation, the billboard 7 can play the role of displaying advertisements. At the same time, since the billboard 7 is rotatably connected to the fixing frame 5 at three-quarters of its height, when the external airflow blows to the surface of the billboard 7, the billboard 7 can be deflected. Then, since the fixing clamp 4 made of stainless steel can play a counterweight effect at the bottom of the billboard 7, the billboard 7 will recover after deflection. Moreover, the elastic rope 3 can not only limit the deflection range of the billboard 7, but also assist its recovery process through its own elastic force. Therefore, the external airflow can make the billboard 7 deflect first and then recover continuously. In this case, the billboard 7 made of grating cards can make the advertising pictures on its surface produce dynamic effects.

[0032] After the device is used, the cover plate 8 can be pressed to retract the billboard 7 into the folding box 1. When the sliding sleeve 2 is lowered to the spring sheet 11 at the lower end along with the fixed frame 5, the clamping block 12 at the lower end can maintain the storage state of the fixed frame 5 by fixing the sliding sleeve 2. Then, the two folding boxes 1 can be folded together to facilitate the carrying and use of the device.

[0033] Example 2

[0034] Refer to the attached Figure 4The present application provides a foldable billboard. Compared with Example 1, in order to further maintain the folded and combined state of the two foldable boxes 1, a fixing pile 14 is fixedly connected to one side of the two foldable boxes 1. The two fixing piles 14 are both semi-cylindrical. The foldable box 1 is fixedly connected to a connecting rope 15 on one side of the fixing pile 14. One end of the connecting rope 15 is fixedly connected to a ring 16. The diameter of the ring 16 is equal to that of the two fixing piles 14. After the two foldable boxes 1 are folded and combined, the two foldable boxes 1 can be fixed by putting the ring 16 on the two fixing piles 14, so that the two can maintain the combined state, ensuring that the relative state of the two will not change further during the carrying or transportation process.

[0035] Working principle: After the device is used and the two folding boxes 1 are folded together, the ring 16 can be put on the two fixing piles 14, and the ring 16 can maintain the folded and combined state of the two folding boxes 1 by limiting the two fixing piles 14, thereby ensuring the convenience of carrying and using the device.

[0036] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
