Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of publicity equipment, in particular to a multimedia publicity column which is convenient for replacing graphic and text carriers. Background Art
[0002] Multimedia billboards usually include a support frame, a billboard mounted on the support frame, and a display screen. Existing multimedia billboards usually use different forms of graphic carriers, such as posters, promotional papers, and billboards, to fix them to the billboards by gluing or magnetic attraction. Since existing billboards are mostly single-sided, their usable area is limited. Furthermore, billboards are usually made of acrylic, KT, and stainless steel. Stainless steel is usually heavier than posters and promotional papers, while acrylic and KT are usually thicker than posters and promotional papers. This makes it difficult to fix billboards magnetically. If the billboards are fixed by gluing, the board surface needs to be cleaned before re-pasting (existing billboards often have the writing surface and the gluing surface on the same side, and failure to clean them in time often affects writing). This makes cleaning difficult and the replacement of graphic carriers inconvenient. Utility Model Content

DETAILED DESCRIPTION
[0018] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.
[0019] like Figure 1-5 As shown, a multimedia billboard for facilitating replacement of graphic and text carriers comprises a support frame 1, a billboard 2 and a display screen 3 arranged on the support frame 1, the billboard is provided with a rotating assembly for rotating the billboard 2, the billboard 2 is a multi-layer structure and is sequentially provided with a paint writing layer 201, a polystyrene filling layer 202 and an iron magnetic layer 203, the outer surface of the iron magnetic layer 203 is provided with a slide groove 4, both ends of the slide groove 4 are connected with sliders 5, the top of the slider 5 is fixed with a mounting plate 6, the side of the slider 5 and the opposite side of the two sliders are rotatably connected with a threaded rod 7, the threaded sleeves 8 are threadedly connected between the threaded rods 7, the mounting plate 6 is provided with a mounting groove 9 for mounting graphic and text carriers on the opposite side, and the groove wall of the mounting groove 9 is penetrated by a clamping bolt 10 for clamping the graphic and text carrier.
[0020] Working principle: One side of the publicity board 2 is a paint writing layer 201, i.e., the writing surface, and the other side is an iron sheet magnetic layer 203, i.e., the fixing surface, which is equivalent to increasing the use area of the publicity board 2. The slide groove 4 is preferably vertically arranged in the middle position of the publicity board 2, and the mounting groove 9 should be provided with an internal threaded through hole that matches the thread of the clamping bolt 10, so that the graphic carrier between the mounting grooves 9 can be clamped by rotating the clamping bolt 10; Usage steps: If you need to replace thinner or lighter graphic carriers such as posters and promotional papers, turn the publicity board 2 to the fixing surface, and then Posters, promotional papers, etc. can be fixed on the iron magnetic layer 203 through the magnetic part; if it is necessary to replace a heavier or thicker graphic carrier, such as a billboard, the threaded sleeve 8 is rotated so that the billboard can be placed between the mounting grooves 9 at both ends. After placing the billboard, the threaded sleeve 8 is rotated in the opposite direction to shorten the distance between the mounting grooves 9, and the position of the billboard is adjusted so that it can be located in the middle of the propaganda board 2, and the billboard is clamped by the clamping bolt 10; if it is necessary to issue some temporary notices, the propaganda board 2 can be turned over to the writing surface by rotating the assembly and writing can be done.
[0021] Preferably, the rotating assembly includes a rotating shaft 11 that passes through the propaganda board 2 and is fixed to the propaganda board 2. The rotating shaft 11 can be rotatably mounted on the support frame 1 and one end of the rotating shaft 11 extends out of the support frame 1 and is connected to a rotating cap 12. The rotating shaft 11 is provided with a pin 13 for locking the rotation angle. The pin 13 passes through the rotating shaft 11 and the support frame 1 in the vertical direction. The installation of the rotating assembly can be completed by, but is not limited to, the above method. When rotating: pull out the pin 6, flip the propaganda board 2 vertically, and reinsert the pin 6. The rotating assembly can flip the propaganda board 2 and lock it. The structure is simple and easy to operate, and the stability is also high.
[0022] Preferably, a rain shield 14 is fixedly connected to the top of the support frame 1, and an arc-shaped water receiving trough 15 with a concave cross-section is opened on the top of the rain shield 14. The arc-shaped water receiving trough 15 is connected to a drain pipe 16 on one side, and the drain pipe 16 is preferably connected to the sewer or the ground through a hose. The rain shield 14 is used to shield components such as the propaganda board 2 and the display screen 3 from rain and sun. The arc-shaped water receiving trough 15 is used to collect rainwater to prevent the rain shield 14 from forming a rain curtain in front and behind, causing rainwater to splash onto the propaganda board 2 and the display screen 3, and at the same time facilitate passers-by to temporarily shelter from the rain.
[0023] The top of the lower baffle 18 is fixedly connected with a placement box 21. The upper baffle 17, the lower baffle 18 and the transparent dust covers 19 on the front and back sides constitute a dustproof chamber, which can protect the propaganda board 2 and the graphic carriers on the propaganda board 2. When the propaganda board 2 is flipped over, the transparent dust cover 19 needs to be opened first. The telescopic rod 20 is used to make it easier to open the transparent dust cover 19. The telescopic rod 20 is preferably set to be hidden and can be installed by embedding in the support frame 1. The placement box 21 is used to place chalk for writing and magnets for magnetic attraction, etc., which improves the convenience of use of the propaganda column. The material of the transparent dust cover 19 can be organic glass, which is lighter than ordinary glass, easier to open, more transparent and has a better display effect.
[0024] Preferably, a plurality of support rods 22 are fixed to the bottom of the support frame 1. The support frame 1 is usually provided with two support rods. Preferably, eight support rods 22 are provided and are respectively provided on the four sides of the two support frames 1 to enhance the fixing effect of the support frame 1 and reduce shaking.
[0025] Preferably, the clamping bolt 10 is fixed with a rubber sheet 23 at one end located in the mounting groove 9. Since rubber has a large friction coefficient, it can be used to enhance the clamping effect of the clamping bolt 10. The rubber sheet 23 is preferably arranged to have a large contact area with the graphic carrier to reduce the pressure on the contact surface, so that the clamping bolt 10 is not easily damaged when clamping some soft materials, such as KT board.
[0026] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
