Technical Field

[0001] The utility model relates to the technical field of advertising signboards, in particular to a fixing device for advertising signboards which is easy to install. Background Art

[0002] Advertising signs are signs set up by businesses to promote their products or services. They can effectively promote the business's brand and products. Currently, advertising signs are usually placed in fixed devices to provide support and protection for the advertising signs.

[0003] The current advertising sign fixing devices on the market have the limitation that the glass windows cannot be opened quickly to achieve rapid installation and removal of the signs. The entire disassembly and assembly process often requires workers to remove multiple screws one by one, which greatly reduces the convenience of installing and subsequently disassembling the advertising signs. At the same time, the positioning of the advertising signs inside the fixing device is also relatively cumbersome. Therefore, in order to solve these problems, we need to consider designing a fixing device for advertising signs that is easy to install. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a fixing device for an advertising sign that is easy to install. In order to solve the problem of loading and unloading, the limiting plate cooperates with the positioning groove to limit the advertising sign body, and the circular connecting frame can be fixed by two permanent magnets. An auxiliary mechanism is also provided to assist the staff in rotating out the circular connecting frame and conveniently replacing the advertising sign body, thereby reducing the workload.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 4 A fixing device for an advertising sign that is easy to install includes a shell 1, a placement groove 2 is opened on the front side of the shell 1, an advertising sign body 9 is set in the placement groove 2, a positioning groove 3 is opened on the inner bottom of the placement groove 2, which can realize the positioning of the advertising sign body 9 before limiting. The front side of the shell 1 is rotatably connected to a circular connection frame 4, and a glass window 5 is set on the inner side of the circular connection frame 4. A mounting groove 6 is opened on the inner top of the placement groove 2, and a rectangular inner groove 12 is horizontally opened on the right inner wall of the placement groove 2. The lower end of the shell 1 is fixedly connected to a base 17;

[0021] Among them, two telescopic rods 7 are installed on the inner top of the installation groove 6. Both telescopic rods 7 are electric telescopic rods. The telescopic ends of the two telescopic rods 7 are fixedly connected to the limit plate 8. The limit plate 8 cooperates with the positioning groove 3 to achieve stable positioning of the advertising sign body 9. The lower end of the advertising sign body 9 is in contact with the inner wall of the positioning groove 3, and the upper end of the advertising sign body 9 is in contact with the lower end of the limit plate 8.

[0022] Among them, two fixing blocks 10 are fixedly connected to the right inner wall of the placement slot 2, and permanent magnets 11 are provided on the front sides of the two fixing blocks 10. The circular connection frame 4 cooperates with the two permanent magnets 11. The circular connection frame 4 is made of iron. When the circular connection frame 4 is rotated into the placement slot 2 and fits with the two permanent magnets 11, the magnetic attraction of the two permanent magnets 11 can ensure the fixation of the circular connection frame 4;

[0023] Among them, it also includes an auxiliary mechanism, which is used to assist in opening the circular connecting frame 4. The auxiliary mechanism includes a protrusion 13 arranged in the rectangular inner groove 12. The left side of the protrusion 13 is an arc-shaped surface. The protrusion 13 is slidingly connected to the inner wall of the rectangular inner groove 12. The circular connecting frame 4 cooperates with the protrusion 13. By controlling the protrusion 13 to move left, the right side frame body of the circular connecting frame 4 can be squeezed out from the placement groove 2, thereby releasing the magnetic adsorption of the two permanent magnets 11 on the circular connecting frame 4, which is convenient for the subsequent replacement of the advertising sign body 9. The right side of the protrusion 13 is fixedly connected to the connecting rod 14. The right end of the connecting rod 14 passes through the right inner wall of the rectangular inner groove 12 and is fixedly connected to the pressing block 15. The right side of the protrusion 13 is elastically connected to the right inner wall of the rectangular inner groove 12 by two springs 16.

[0024] In the present invention, before use, first ensure that the limiting plate 8 is at the uppermost end, place the advertising sign body 9 into the positioning groove 3, control the two telescopic rods 7 to drive the limiting plate 8 to move downward until the lower end of the limiting plate 8 is tightly fitted with the upper end of the advertising sign body 9, thus completing the limiting of the advertising sign body 9. The entire limiting process is simple and quick. After the limiting is completed, the return-shaped connecting frame 4 is rotated counterclockwise into the placement groove 2, so that the return-shaped connecting frame 4 is magnetically attracted to the two permanent magnets 11, thereby ensuring the fixation of the return-shaped connecting frame 4;

[0025] When a new advertising sign body 9 needs to be replaced later, the pressing block 15 is pressed to the left, driving the connecting rod 14 and the protrusion 13 to move left synchronously, and at the same time, the two springs 16 are stretched. In the process of the protrusion 13 moving to the left, the arc surface part on the left side will squeeze the right frame of the return-shaped connecting frame 4, causing the right part of the return-shaped connecting frame 4 to move forward a short distance and break away from the magnetic adsorption of the two permanent magnets 11. At this time, the staff can rotate the return-shaped connecting frame 4 out of the placement slot 2 along the pointer, and release the pressing block 15 after rotating it out. Due to the elastic force of the two springs 16, the protrusion 13 can automatically retract into the rectangular inner slot 12. After opening the return-shaped connecting frame 4, the staff can control the limit plate 8 to move up to cancel the limit on the old advertising sign body 9, and then re-limit the new advertising sign body 9. The entire loading and unloading process is convenient and fast, reducing the workload of the staff.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
