Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a picture magnetic attraction device for a signboard. Background Art

[0002] In today's diversified display and information dissemination environment, the demand for display and replacement of images is becoming increasingly frequent. Traditional image fixing methods often have many disadvantages, which greatly limit the flexibility and efficiency of image display. It is in this context that the image magnetic device came into being. It uses the principle of magnetic adsorption to provide a new solution for the fixation and replacement of images. However, the image magnetic device that relies solely on magnetic adsorption may not be stable enough in some cases. For example, in places with a large flow of people or when impacted by external forces, the image may become loose or even fall off. Therefore, when designing a image magnetic device for a signboard, the issue of auxiliary fixing devices also needs to be considered to ensure that the image can be firmly fixed on the signboard in various environments. At the same time, rapid replacement of images has become an urgent problem to be solved in signboard design. In some places where information needs to be updated frequently, such as promotional activity areas in shopping malls, exhibition sites, etc., the image of the signboard needs to be able to be replaced in a short time to ensure the timeliness and accuracy of the information.

This patent mainly prevents the signboard body from falling off and being dislocated when it is subjected to lateral force by setting magnets and fixing mechanisms. By setting movable columns, connecting rods and push plates, the signboard body can be easily removed, thereby achieving the purpose of facilitating the disassembly of the signboard body. However, this device cannot effectively further assist in fixing the signboard body. For this reason, we propose a picture magnetic device for the signboard. Utility Model Content

[0023] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Please see the attached Figure 1 -Attached Figure 5 The present invention relates to a magnetic device for attracting images of signage. The magnet 2 is located at the rear side of the shell 1. A transparent window 3 is provided on the front side of the shell 1. Through the transparent window 3, the image content on the signage adsorbed inside the device can be clearly seen, so that the signage information can be displayed to the observer at a glance, which is convenient for people to read the signage information and can also play a certain protective role on the signage to prevent it from being scratched and damaged by the outside world. A rectangular long opening is provided on the top surface, which can be used to easily put in and take out the signage, and a positioning base 4 is installed at the bottom end of the interior to provide an accurate positioning and support for the signage. A slide groove 5 is provided in the center of the rear side of the shell 1. The rear side of the positioning base 4 is provided at the It is fixedly connected with a slider 6, which is located inside the slide groove 5 and is connected to a first moving rod 7 at the top center. Through the connection with the slider 6, it can drive the positioning base 4 to move up and down in the slide groove 5. The first moving rod 7 passes through the top surface of the shell 1 and is connected to a first motor 8 at the other end. Clamping plates 9 are installed on both sides of the shell 1. After the identification plate is placed in the device, its two sides are clamped to prevent the identification plate from shaking or loosening in the device. A second moving rod 10 is fixedly connected to the rear center of the clamping plate 9, which drives the clamping plate 9 to move back and forth, thereby realizing the clamping and loosening of the identification plate. The second moving rod 10 passes through the back of the shell 1 and is connected to a second motor 11 at the other end.

[0025] In the first embodiment, the rear side of the positioning base 4 is in close contact with the rear side of the interior of the shell 1 and is provided with a square groove, which is located directly below the rectangular strip opening. The slide groove 5 is connected to the slider 6. One end of the first movable rod 7 is connected to the top surface of the slider 6, and the other end is connected to the first motor 8. The first motor 8 is located on the top surface of the shell 1. The clamping plate 9 is located on both sides of the interior of the shell 1 and is semi-frame-shaped. The upper and lower ends are in close contact with the upper and lower ends of the interior of the shell 1. One end of the second movable rod 10 is fixedly connected to the center of the rear side of the clamping plate 9, and the other end is connected to the second motor 11. The second motor 11 is located on the rear side of the shell 1;

[0026] Specifically, a square groove is provided on the positioning base 4, which is just below the square long opening on the top surface of the shell 1, so that the sign can fall smoothly into the square groove of the positioning base 4 through the square long opening, realizing accurate positioning and placement. The slide groove 5 on the rear side of the interior of the shell 1 and the slider 6 on the rear side of the positioning base 4 are interconnected, so that the slider 6 can slide smoothly in the slide groove 5. At the same time, the close cooperation between the slider 6 and the slide groove 5 also ensures the stability and accuracy of the positioning base 4 during movement, and there will be no deviation from the track or jamming. The shape of the clamping plate 9 is semi-frame-shaped, which can better adapt to the shape of the sign and effectively clamp the two sides of the sign. The upper and lower ends of the clamping plate 9 are in close contact with the upper and lower ends inside the shell 1, which can ensure that the clamping plate 9 remains stable during work without shaking or loosening. At the same time, it can also prevent the sign from moving up and down in the device, further improving the fixing effect of the sign.

[0027] In the second embodiment, the magnet 2 includes a magnetic strip 21 and a magnetic round block 22. The magnetic strip 21 and the magnetic round block 22 are distributed on both sides of the slide 5. The magnetic round block 22 is thinner than the magnetic strip 21 and has a stronger magnetic strength than the magnetic strip 21. An array of threaded holes is provided on the back of the shell 1. A connecting shaft is fixedly connected to the back of the magnetic round block 22. The connecting shaft passes through the threaded hole and a rotating block is provided at the other end. A thread is provided on the outside of the connecting shaft. The thread and the threaded hole are connected to each other. A handle 12 is provided on the top surface of the shell 1. Hanging blocks are provided on both sides of the handle 12. A light bar is provided on the top surface of the inner part of the shell 1. The light bar is located at the front end of the pressing plate 9.

[0028] Specifically, the magnet 2 is composed of a magnetic strip 21 and a magnetic round block 22. The magnetic strip 21 has a certain length and width, which can provide a relatively uniform magnetic adsorption effect. The magnetic strip 21 and the magnetic round block 22 are carefully distributed on both sides of the slide groove 5, which can ensure that the identification plate can be subjected to the effect of magnetic force from multiple directions after being placed in the device, so that it can be more firmly adsorbed on the positioning base 4 and will not fall or shift easily. The function of the connecting shaft is to connect the magnetic round block 22 with the shell 1, and it also provides the possibility of adjustment of the magnetic round block 22. At the other end of the connecting shaft, a rotating block is provided. The design of the rotating block is convenient for the operator to rotate. By twisting the rotating block, the distance between the magnetic round block 22 and the identification plate can be adjusted to achieve the adjustment of the magnetic adsorption effect. At the same time, the threaded connection method is convenient for installation and disassembly. When the magnetic round block 22 needs to be replaced or repaired, the connecting shaft can be easily unscrewed from the threaded hole. The function of the hanging block is to hang the device on a wall or other fixed object to achieve different installation methods.

[0029] Working principle:

[0030] First, put the identification plate into the device through the rectangular strip opening on the top surface of the shell 1. The identification plate naturally falls into the square groove of the positioning base 4 under the action of gravity. The slider 6 on the rear side of the positioning base 4 cooperates with the slide groove 5 on the rear side of the inner part of the shell 1, so that the positioning base 4 can move smoothly in the track defined by the slide groove 5. At this time, the first motor 8 is started, and the slider 6 is driven up and down in the slide groove 5 by the first moving pull rod 7, thereby adjusting the height of the positioning base 4 so that the identification plate can be pushed out for replacement. The magnet 2 located on the rear side of the inner part of the shell 1 includes a magnetic strip 21 and a magnetic round block 22. They are distributed on both sides of the slide groove 5 and use magnetic force to absorb the identification plate to ensure that it is stably fixed on the positioning base 4. Among them, the magnetic round block 22 is thinner but has stronger magnetic strength, and can absorb identification plates of different materials according to actual needs. At the same time, the threaded hole on the back of the shell 1 and the back of the magnetic round block 22 The connecting shafts are connected to each other through threads. By rotating the rotating block at the other end of the connecting shaft, the distance between the magnetic block 22 and the sign can be adjusted to further optimize the magnetic adsorption effect. When the sign is placed, the second motor 11 is started, and the second moving pull rod 10 pushes the clamping plates 9 on both sides of the inside of the shell 1 to move forward. The clamping plates 9 are semi-frame-shaped, and the upper and lower ends are in close contact with the upper and lower ends of the inside of the shell 1. The sign can be clamped and fixed from both sides to prevent the sign from shaking or shifting during use. In addition, the light bar on the top surface of the inside of the shell 1 is located at the front end of the clamping plate 9, which can provide lighting in insufficient light, making the picture on the sign more clearly visible. The handle 12 on the top surface of the shell 1 and the hanging blocks on both sides facilitate the carrying and installation of the device. It can be carried or hung in a suitable position according to different usage scenarios. At this point, the entire workflow ends.
