Description

Technical Field

[0001] The utility model belongs to the field of parking equipment, and in particular relates to a foldable and movable information display board. Background Art

[0002] The already implemented smart roadside parking areas or centralized large-scale smart parking lots have many entry directions and a large space inside. There is a need to set up display boards at multiple locations to promptly remind or display certain information (such as charging information, construction information, event information, etc.) to visitors.

[0003] At present, most parking lots adopt the method of erecting fee information signs on the roadside. The style is single and the construction mode is mostly installed on the curb. During installation, it is necessary to dig the ground and fill it with concrete to erect poles. Although it can withstand wind and rain of general intensity, if it encounters strong typhoons, heavy rains, etc., there is a risk of inversion, which poses certain safety hazards. In addition, it has poor flexibility and cannot change the placement direction and quantity as needed.

[0004] The demand for multi-point display boards in smart parking lots is actually a multi-point setting based on specific circumstances. For example, conspicuous parking lot signs and fee information display boards are basically required at the entrances. If there are construction or maintenance areas, display boards need to be set up on the periphery. If there are large-scale venue activities, direction guidance information, safety reminder information, activity information and other display boards need to be set up. That is, depending on the situation, the location of the display boards and the number of display boards used are also different, and there is a need to move the display boards in batches for placement or recycling.

[0005] The patent document with application number CN201821325105.4 discloses an easily detachable signboard, whose structure includes a fixed outer frame, a signboard, a telescopic rod, an adjusting knob, a support rod, a mounting hole groove, an aesthetic chassis, and a weighted chassis. The signboard is installed inside the fixed outer frame by a sleeve-fitting manner, the fixed outer frame is installed on the top of the telescopic rod by a buckling manner, the telescopic rod is installed inside the support rod by an adjusting knob, and the weighted chassis is installed at the bottom of the aesthetic chassis by a buckling manner; the fixed outer frame is composed of an outer frame body, a fixed cover plate, a flip bearing, a reset spring, a limit plate, and a buckle. A flip bearing is provided on the right side of the outer frame body by an embedded manner, the flip bearing is installed on the left side of the flip bearing by a sleeve-fitting manner, the buckle is integrated with the bottom of the fixed cover plate by a fusion manner, the reset spring is arranged at the lower right end of the outer frame body, and the limit plate is installed between the reset spring and the buckle by a buckling manner.

[0006] When it is necessary to place a flyer, the above-mentioned prior art pulls the limit plate to squeeze the return spring and move it to the right side of the outer frame body, so that the buckle is released, and the fixed cover plate is driven to pop open by the flip bearing, and then the flyer is placed in the outer frame body. During installation, the fixed cover plate is buckled down, and the buckle squeezes the limit plate to make it move. After the fixed cover plate is fully buckled, the return spring pops out the limit plate, and the fixed buckle is buckled, which solves the problem of the trouble of replacing the advertising leaflets on the billboard, and the structure is relatively light and can be disassembled.

[0007] However, the above-mentioned easily detachable billboards have irregular shapes after disassembly, and are difficult to store or carry in groups. The inventor believes that there is still room for improvement in the existing billboard structure. Therefore, the utility model aims to develop and improve the structure of the billboard to further facilitate the staff's batch movement for placement or recycling. Summary of the invention

[0061] like Figures 1 to 8 As shown, a foldable and movable information display board includes a base shell 5 made of thickened stainless steel material, a roller group B arranged at the bottom of the base shell 5 and two transparent card shells A, which are set as an upper transparent card shell A1 and a lower transparent card shell A2. The transparent card shell A is thickened transparent acrylic, and the lower transparent card shell A2 is installed on the top of the base shell 5.

[0062] The interior of the transparent card shell A has a flat hollow structure that runs through in the vertical direction, which is used to accommodate information display printed materials (such as promotional posters, paper with charging information printed on it, etc.). A flexible connecting cylinder 4 is provided between the two transparent card shells A to connect and communicate with each other. The transparent card shells A can be folded in half through the deformation of the flexible connecting cylinder.

[0063] A detachable rigid snap-fit ​​structure is also provided between the two transparent card shells A, and the transparent card shells A are kept in a relatively static state, that is, in an inflexible vertical state, by the rigid snap-fit ​​structure. The transparent card shells A in a relatively static state stand vertically above the base shell 5 to display information.

[0064] The interior of the base shell 5 is a hollow bottom cavity, and a counterweight (such as a sandbag, a container filled with water, a weight, etc., not shown in the drawings) is placed in the bottom cavity to lower the center of gravity of the information display board so that this embodiment is not easy to fall over; the opposite side walls of the base shell 5 are respectively provided with corresponding hooks 506 and hook holes 502.

[0065] Compared with the prior art, the present embodiment divides the display board with a larger area into two transparent board shells A and connects them through a flexible connecting tube 4, so that the folded transparent board shell A can be neatly folded on the top surface of the base shell 5, which is easy to store. At the same time, a rigid clamping component is provided to maintain the vertical state. The present embodiment can conveniently switch between the folded state and the vertical display state.

[0066] Taking into account that the present embodiment is provided with a counterweight, the roller group B is provided to facilitate the staff to move the present embodiment with less effort. At the same time, the present embodiment is provided with corresponding hooks 506 and hook holes 502 on the opposite side walls of the base shell 5. When a batch of the present embodiments needs to be moved, it is only necessary to connect multiple present embodiments through the hooks 506 and the hook holes 502, and then pull and move them in rows, so that the staff can place or recycle them at multiple locations in the parking area conveniently.

[0067] In this embodiment, the flexible connecting cylinder 4 is a retractable accordion cylinder, the ends of which are fixed to the inner surfaces of two adjacent transparent card shells A by gluing or other methods, and the accordion cylinder is made of transparent material.

[0068] The left and right sides of the bottom opening of the inner surface of the upper transparent card shell A1 protrude downward to form two blocks A101, and the two blocks A101 are located on the outside of the accordion pleated tube. The blocks A101 form a transition fit with the top opening of the inner surface of the lower transparent card shell A2, serving as the rigid clamping structure.

[0069] In this embodiment, all the transparent card shells A are connected in sequence through the flexible connecting cylinder 4, and the top surface of the base shell 5 is provided with a slot 505 formed by a downward depression, and the lower transparent card shell A2 is vertically inserted and fixed in the slot 505.

[0070] The base shell 5 is provided with upwardly protruding slider seats 503 at both ends of the slot 505, and the sliders 503a of the two slider seats 503 are arranged opposite to each other. The left and right sides of the lower transparent card shell A2 inserted into the slot 505 are provided with sliding grooves A201 adapted to the sliders 503a, and the lower transparent card shell A2 and the slider seat 503 form a sliding and rotating connection.

[0071] The length of the slide groove A201 is greater than the distance between the slider 503a and the bottom of the slot 505. The lower transparent card shell A2 slides in the vertical direction to disengage from the slot 505, and then is rotated to be flat on the top surface of the base shell 5. The upper transparent card shell A1 is folded and placed on the top surface of the lower transparent card shell A2 through the deformation of the flexible connecting tube.

[0072] More specifically, the slot 505 is transversely disposed in the middle of the base shell 5 .

[0073] The slide groove A201 extends from the middle of the side surface of the lower transparent card shell A2 to a position near the end corner. The end of the slide groove A201 near the end corner is a rotating groove A202, and the end near the middle of the side surface is a flat groove A203. The flat groove A203 is skewed relative to the length direction of the slide groove A201 toward the front of the lower transparent card shell A2, thereby limiting the displacement of the transparent card shell A so that the transparent card shell A in the folded state will not easily slide along the slide groove A201.

[0074] The lower transparent card shell A2 is pulled up vertically so that the bottom is completely out of the slot 505, and the slider 503a slides along the slide groove A201 into the rotation slot A202. The lower transparent card shell A2 rotates horizontally (backward), and the bottom moves smoothly toward the front direction of the base shell 5. The slider 503a enters the flat slot A203, and the transparent card shell A is placed flat on the top surface of the base shell 5 and the center is aligned, so that the shape of this embodiment is regular and the center of gravity is stable after folding.

[0075] In this embodiment, the top surface of the base shell 5 is tilted downward from the two side groove edges of the slot 505 to avoid forming a receiving plane, so that rainwater, fallen leaves, etc. cannot stay on the surface.

[0076] The top surface of the inclined base box protrudes upward to form a plurality of reinforcing ribs 501, the top surfaces of the reinforcing ribs 501 are flush, and the distance between the top of the reinforcing ribs 501 and the slider seat 503 is equal to or greater than half the thickness of the transparent card shell A. The reinforcing ribs 501 support the transparent card shell A in the folded state, so that the transparent card shell A folded and placed on the top surface of the base shell 5 is placed more stably.

[0077] Specifically, each of the reinforcing rib sheets 501 is disposed in the longitudinal direction, and all of the reinforcing rib sheets 501 are arranged in the transverse direction.

[0078] In this embodiment, the hook hole 502 is provided on the front of the base shell 5, and a cover door 504 is provided on the back of the base shell 5. The weight is placed in the bottom cavity by opening the cover door 504. A flexible belt (i.e., a rope) is connected to the inner side of the cover door 504, and the flexible belt is connected to the hook 506. When there is no need to pull multiple hooks 506, the hook 506 can be hidden in the base box. When the hook 506 is needed, the cover door 504 is opened and the hook 506 is pulled out.

[0079] In this embodiment, the roller set B includes two universal wheels B6 and two rollers B7. The two universal wheels B6 are located on the same side as the hook hole 502, that is, the front direction of this embodiment, and the two rollers B7 are installed near the back. After the hook 506 is hooked on the hook hole 502, the information display board where the hook 506 is located generally moves in front, and the universal wheel B6 of the information display board where the hook hole 502 is located is in front, which is more convenient for steering.

[0080] In this embodiment, the slot 505 includes a strip slot 505a that passes through the top surface of the base shell 5 and supporting slot seats 505b located at both ends of the bottom of the strip slot 505a, and the supporting slot seats 505b support the bottom two corners of the lower transparent card shell A2.

[0081] A strip light source 8 (LED light board) is fixed to the bottom of the supporting groove seat 505b, and the two ends of the strip light source 8 are respectively fixed to the two supporting groove seats 505b. The strip light source 8 emits light toward the transparent card shell A. A power source (battery, not shown in the drawings) for supplying power to the strip light source 8 is provided in the bottom cavity. In the case of insufficient light, the strip light source 8 can be turned on.

[0082] In this embodiment, soft plastic strips are fixed on both sides of the strip-shaped slot 505a. The soft plastic strips do not hinder the lower transparent card shell A2 from being inserted into the slot 505. The soft plastic strips are in contact with the outer surface of the lower transparent card shell A2, thereby preventing rainwater, sand and stones from entering the interior of the base box.

[0083] In this embodiment, a removable top cover 3 is provided on the top of the upper transparent card shell A1, and the top cover 3 protrudes toward the interior of the upper transparent card shell A1 to form a convex beam 301. The front and rear surfaces of the convex beam 301 protrude outward to form a plurality of hanging nails 301a. By punching holes on the top of the printed matter, it can be hung on the hanging nails 301a, and double-sided display and promotion can be achieved.

[0084] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation mode. Therefore, the utility model is not limited to the specific implementation modes disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of explanation and do not constitute any limitation to the utility model.
