Technical Field

[0001] This utility model relates to the field of advertising technology, and more specifically, to a poster board for use in elevators. Background Technology

[0002] Elevator advertising screens are tools used to display and promote information. Some elevator advertising screens place posters inside a frame and then display them through a glass window. Elevator poster advertising is the most mainstream form of elevator advertising, and its main characteristics are the uniqueness of the advertiser and the prominent display location.

[0003] For example, the elevator advertising screen disclosed in authorization announcement number CN209729437U is easy to install. It changes the traditional frame structure, making it easier to replace posters, saving manpower, and the advertising screen has a longer service life and good applicability.

[0004] The above method involves modifying the traditional frame structure by adding a fixing plate and a limiting device. However, this solution can only display the same advertisement image per cycle, making the elevator poster advertisement display very monotonous. This requires frequent changes to the poster. When changing the advertisement content, the outer frame of the poster board needs to be opened and the poster replaced, which is quite troublesome. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a poster board for elevators that allows posters to be replaced without opening the poster frame.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A poster board for elevators includes a mounting frame and a transparent plate connected to the end face of the mounting frame. A receiving groove for placing posters is provided between the mounting frame and the transparent plate. The inner sidewall of the receiving groove has two rotating holes, a first rotating hole and a second rotating hole.

The end face of the sealing plate has a slider that mates with the sliding groove.

[0009] A fixing groove is provided between the two sliders, and a fixing component is provided on the inner wall of the fixing groove.

[0010] The present invention is further configured such that: the clamping member has two sets, the two sets of clamping members are symmetrical about the center line of the adjusting rod, the clamping member includes a connecting rope and a clamp, one end of the connecting rope is fixedly connected to the adjusting rod and the other end is fixedly connected to the clamp, and the length of the connecting rope is greater than the height of the mounting frame.

[0011] The present invention is further configured such that: the fixing member has several groups, each group of fixing members is provided on the two inner walls of the fixing groove, the fixing member includes a spring and a magnetic sheet, one end of the spring is fixedly connected to the inner wall of the fixing groove and the other end is fixedly connected to the magnetic sheet, and the two magnetic sheets in each group are magnetically attracted to each other.

[0012] The present invention is further configured such that: the turntable is provided with a handle, the side wall of the handle is provided with a magnetic plate, the side wall of the mounting frame is provided with a slot corresponding to the handle, and a magnet is provided in the slot to be magnetically attracted to the magnetic plate.

[0013] The present invention is further configured such that: the adjusting rod has an opening, and one end of the connecting rope is inserted into the connecting hole and then knotted to fix it.

[0014] Compared with the shortcomings of the prior art, the beneficial effects of this utility model are as follows:

[0015] By adding connecting ropes and clips, one end of the poster is clamped and fixed. Then, the handle is turned to rotate the adjusting rod, which in turn retracts the connecting rope. The two magnetic pieces are then separated, and the lower end of the poster is placed between them. The sealing plate is connected to the mounting frame via a slider and a groove. Under the action of the magnetic pieces, the lower end of the poster is clamped, allowing the poster to be displayed straight within the mounting frame. To replace the poster, simply rotate the handle in the opposite direction, making disassembly quite convenient. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Working principle: When installing the poster, first remove the sealing plate 7, then rotate the turntable 4 to extend the connecting rope 9 to the lower end of the receiving cavity 2. Then fix the upper end of the poster with the clip 10. Then rotate the turntable 4 again to retract the connecting rope 9, which will move the poster until it is hung up. Then place the lower end of the poster between the two magnetic pieces 13. Then align the slider 8 with the slide groove 6 and connect the sealing plate 7 to the mounting frame 1. The magnetic force between the two magnetic pieces 13 is just enough to fix the lower end of the poster without clamping the poster too tightly when the sealing plate 7 moves, so that the sealing plate 7 cannot move.

[0023] When changing the poster, rotate handle 14 in the opposite direction, the connecting rope 9 will move the poster down, and finally remove both ends of the poster from between clip 10 and the two magnetic pieces 13.

[0024] Repeat the above steps to get the next poster.

[0025] like Figures 1 to 3 As shown:

[0026] The device includes a mounting frame 1 and a transparent plate connected to the end face of the mounting frame 1. There is a receiving groove between the mounting frame 1 and the transparent plate for placing the poster. The inner side wall of the receiving groove is provided with a first rotating hole and a second rotating hole. An adjusting rod 3 is rotatably connected between the first rotating hole and the second rotating hole. The adjusting rod 3 is provided with an opening. One end of the connecting rope 9 is inserted into the connecting hole and then tied to fix it, so as to prevent the connecting rope 9 from slipping and affecting the shrinkage effect during the rotation of the adjusting rod 3.

[0027] The second rotating hole penetrates the side wall of the mounting frame 1. A gear is provided inside the second rotating hole. One end of the adjusting rod 3 is provided with a tooth that meshes with the gear. The tooth is connected to a turntable 4. A handle 14 is provided on the turntable 4. A magnetic plate 15 is provided on the side wall of the handle 14. A slot is provided on the side wall of the mounting frame 1 corresponding to the handle 14. A magnet 16 is provided in the slot that is magnetically attracted to the magnetic plate 15. When the adjusting rod 3 does not need to be rotated, the magnetic plate 15 is magnetically attracted to the magnetic strip, fixing the handle 14, and thus fixing the turntable 4.

[0028] The lower end face of the mounting frame 1 has a placement groove 5 that communicates with the receiving cavity 2. The adjusting rod 3 is provided with a clamping component corresponding to the placement groove 5. There are two sets of clamping components, which are symmetrical about the center line of the adjusting rod 3. The clamping component includes a connecting rope 9 and a clamp 10. One end of the connecting rope 9 is fixedly connected to the adjusting rod 3 and the other end is fixedly connected to the clamp 10. The length of the connecting rope 9 is greater than the height of the mounting frame 1, so that the connecting rope 9 can be lowered and connected to the poster.

[0029] The placement groove 5 has sliding grooves 6 on both sides, and a sealing plate 7 is slidably connected to the sliding groove 6. The end face of the sealing plate 7 is provided with a slider 8 that mates with the sliding groove 6. The sealing plate 7 is connected to the mounting frame 1 by the slider 8 engaging with the sliding groove 6.

[0030] A fixing groove 11 is provided between the two sliders 8, and a fixing component is provided on the inner wall of the fixing groove 11. There are several sets of fixing components, and each set of fixing components is provided on the two inner walls of the fixing groove 11. The fixing component includes a spring 12 and a magnetic sheet 13. One end of the spring 12 is fixedly connected to the inner wall of the fixing groove 11, and the other end is fixedly connected to the magnetic sheet 13. The magnetic force between the two magnetic sheets 13 is just enough to fix the bottom of the poster, but not so tight as to prevent the sealing plate 7 from moving when it moves. The two magnetic sheets 13 in each set attract each other magnetically to fix the bottom of the poster.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
