Description

Technical Field

[0001] This utility model relates to the field of hanging fixtures, specifically a magnetic double-layer hanging fixture. Background Technology

[0002] Advertising light boxes typically use materials such as vacuum forming, acrylic, and printed fabric as base materials, employing a box-type hollow structure as an advertising medium. They are waterproof and illuminated, primarily suitable for indoor and outdoor advertising. Common types include: ultra-thin soft film light boxes, vacuum-formed light boxes, crystal light boxes, fabric light boxes, and snap-on light boxes.

[0003] Patent application number 202321939082.7 discloses a magnetic hanging device, including a horizontal bar located inside a lightbox and fixed at both ends to the inner wall of the lightbox. A buckle is slidably connected to the horizontal bar, and a first magnet block located inside the lightbox is disposed on the buckle. A second magnet block located outside the lightbox and pressing the lightbox fabric against the first magnet block is attracted to the first magnet block. A hanging bracket for suspending products outside the lightbox is disposed on the second magnet block. In the process of developing this utility model, the inventors discovered that at least the following problems remain unsolved in the prior art: by placing the horizontal bar inside the lightbox and fixing both ends to the inner wall of the lightbox, wherein the buckle is slidably connected to the horizontal bar... The first and second magnetic blocks are located on the inner and outer sides of the lightbox, respectively. These blocks clamp the lightbox fabric, allowing external products to be suspended using the bracket on the second magnetic block. This solves the problem of inconvenient external product hanging. However, traditional magnetic double-layer hangers are fixed to the lightbox interior with bolts. Disassembly and reassembly require removing the track plate first, and when the external force on the hanging rod exceeds the magnetic attraction, the rod may detach from the limiting block. Therefore, the hanger is inconvenient to assemble and disassemble and lacks sufficient stability. A new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a magnetic double-layer hanging device to solve the technical problems of the current magnetic double-layer hanging device being fixed to the inside of the light box with bolts during use, the limiting components on the hanging device requiring the track plate to be removed before disassembly and assembly, and the hanging rod easily detaching from the limiting block when the external force on the hanging rod is greater than the magnetic attraction force. Therefore, the hanging device is not convenient to disassemble and assemble and is not strong enough in use.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A magnetic double-layer hanging device is designed, including a track plate installed inside a lightbox. Partitions are fixedly connected to both sides of the track plate. A guide post is fixedly connected to one side of each partition. A spring is sleeved on the outside of the guide post. The other end of the guide post passes through the interior of a through hole and is slidably connected to a movable abutment block. A threaded hole is opened on the upper surface of the movable abutment block. A pull plate is threadedly connected inside the threaded hole. The lower middle part of the pull plate is slidably connected inside a groove. A convex groove is opened on one side of the track plate. A limit block is slidably connected inside the convex groove. A triangular insert is fixedly connected to one end of the limit block. A first magnet is fixedly connected to the other end of the triangular insert. The outside of the triangular insert is inserted into a triangular slot at one end of a hanging rod. A second magnet is fixedly connected inside the triangular slot.

[0006] Preferably, the other end of the guide post is provided with a fixing screw hole, and a fixing bolt is movably inserted through one side of the movable abutment block. The other end of the fixing bolt is connected to the inside of the fixing screw hole by a thread.

[0007] Preferably, the upper half of the pull plate is rectangular, the middle half is cylindrical with the same diameter as the width of the groove, and the lower half is threaded.

[0008] Preferably, the upper and lower halves of the limiting block are both cuboid in shape, the middle part of the limiting block is cylindrical, the width of the lower half of the limiting block is the same as the width of the upper half of the convex groove, and the length of the lower half is 2 / 3 of the width of the lower half of the convex groove.

[0009] Preferably, the negative end of the first magnet corresponds to the positive end of the second magnet.

[0010] Preferably, a stop block is fixedly connected to one side of the hanging rod, and the stop block is slidably connected inside the stop groove. The stop groove is located on one side of the track plate and is adjacent to the convex groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] When the track plate is installed inside the light box, the two pull plates are first moved relative to each other. At this time, the pull plates will drive the movable abutment block to slide inside the guide post and the track plate, and squeeze the spring so that the movable abutment block moves into the inside of the track plate. Then, the track plate is placed horizontally in an appropriate position inside the light box, and the two pull plates are released. At this time, the spring will generate a rebound force on the movable abutment block, so that the abutting end of the movable abutment block contacts the inner wall of the light box, so that the track plate is abutted inside the light box, which helps to improve the convenience of the hanger during installation and removal.

[0013] When the number of limit blocks needs to be increased, the operator first places the lower half of the limit block parallel to the convex groove, then inserts the lower half of the limit block into the convex groove, and then rotates the limit block so that one end of the triangular insert plate is perpendicular to the upper opening of the convex groove. This achieves the limitation of the limit block when it is installed in the convex groove, thus avoiding the need to remove the track plate first during the installation and removal of the limit block, which improves the convenience of disassembling and assembling the components on the hanger.

[0014] When the hanging rod is installed, the operator can directly insert the triangular slot at one end of the hanging rod into the outside of the triangular insert plate, and let the first magnet and the second magnet attract each other. When the hanging rod is squeezed by longitudinal or lateral external force, the triangular insert plate will limit the position of the hanging rod, so as to prevent the external force on the hanging rod from being greater than the attraction force of the magnet, thus preventing the hanging rod from detaching from the limiting block.

[0015] When the triangular insert is fully inserted into the triangular slot, the stop block on the hanging rod will insert into the stop groove, thus preventing the limit block from rotating during use. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: A magnetic double-layer hanging fixture, see [link / reference] Figures 1 to 7 The system includes a track plate 1 installed inside the light box. Partitions 11 are fixedly connected to both sides of the track plate 1. A guide post 12 is fixedly connected to one side of each partition 11. A spring 13 is fitted around the outside of the guide post 12. The other end of the guide post 12 passes through the interior of a through hole 14 and is slidably connected to a movable abutment block 15. A threaded hole 16 is provided on the upper surface of the movable abutment block 15. A pull plate 17 is threadedly connected inside the threaded hole 16. The lower middle part of the pull plate 17 is slidably connected to the interior of a slide groove 18. One end of the spring 13 abuts against one side of the movable abutment block 15, and the other end abuts against one side of the partition 11. When the track plate 1... When installing inside the light box, first move the two pull plates 17 relative to each other. At this time, the pull plates 17 will drive the movable abutment block 15 to slide inside the guide post 12 and the track plate 1, and squeeze the spring 13 so that the movable abutment block 15 moves into the inside of the track plate 1. Then place the track plate 1 horizontally in the appropriate position inside the light box, and then release the two pull plates 17. At this time, the spring 13 will generate a rebound force on the movable abutment block 15, so that the abutting end of the movable abutment block 15 contacts the inner wall of the light box, so that the track plate 1 abuts against the inside of the light box, which helps to improve the convenience of the hanger during installation and removal.

[0027] It should be noted that the end of the movable support block 15 that contacts the inner wall of the light box is made of rubber, while the other end is made of aluminum alloy.

[0028] It is worth mentioning that, see Figure 2 and Figure 3A U-shaped groove 19 is provided on one side of the track plate 1. A limiting block 2 is slidably connected inside the U-shaped groove 19. The upper and lower halves of the limiting block 2 are both cuboid in shape, and the middle part of the limiting block 2 is cylindrical. The width of the lower half of the limiting block 2 is the same as the width of the upper half of the U-shaped groove 19, and the length of the lower half is 2 / 3 of the width of the lower half of the U-shaped groove 19. When the number of limiting blocks 2 needs to be increased, the operator first places the lower half of the limiting block 2 into the U-shaped groove 19. In the parallel position of 9, the lower half of the limiting block 2 is inserted into the interior of the convex groove 19, and then the limiting block 2 is rotated so that the limiting block 2 drives one end of the triangular insert 21 to be perpendicular to the upper half opening of the convex groove 19, so as to limit the limiting block 2 when it is installed in the convex groove 19, thereby avoiding the need to remove the track plate 1 before disassembling the limiting block 2 during the disassembly and assembly process, which helps to improve the convenience of disassembly and assembly of the components on the hanger;

[0029] It is worth noting that, see Figure 6 and Figure 7 One end of the limiting block 2 is fixedly connected to a triangular insert plate 21, and the other end of the triangular insert plate 21 is fixedly connected to a first magnet 22. The outside of the triangular insert plate 21 is inserted into a triangular slot 24 at one end of the hanging rod 23. The inside of the triangular slot 24 is fixedly connected to a second magnet 25. The negative end of the first magnet 22 corresponds to the positive end of the second magnet 25. When the hanging rod 23 is installed, the operator can directly insert the triangular slot 24 at one end of the hanging rod 23 into the outside of the triangular insert plate 21, and let the first magnet 22 and the second magnet 25 attract each other. When the hanging rod 23 is squeezed by longitudinal or lateral external force, the triangular insert plate 21 will limit the position of the hanging rod 23, preventing the external force on the hanging rod 23 from being greater than the attraction force of the magnet, thus preventing the hanging rod 23 from detaching from the limiting block 2.

[0030] For details, see Figure 5 The other end of the guide post 12 is provided with a fixing screw hole 26. A fixing bolt 27 is movably passed through one side of the movable abutment block 15. The other end of the fixing bolt 27 is connected to the inside of the fixing screw hole 26 by a thread. When the movable abutment block 15 needs to be disassembled, first unscrew the fixing bolt 27 from the inside of the fixing screw hole 26, and then pull the movable abutment block 15 out of the outside of the guide post 12.

[0031] It should be noted that the outer diameter of one end of the fixing bolt 27 is larger than the diameter of the through hole 14.

[0032] Further, see Figure 5The upper half of the pull plate 17 is rectangular, the middle part is cylindrical, and its diameter is the same as the width of the slide groove 18. The lower half is threaded, which facilitates the movement of the pull plate 17 inside the slide groove 18 and makes it easy to assemble and disassemble the lower half of the pull plate 17 with the movable abutment block 15.

[0033] It is worth noting that, see Figure 3 and Figure 6 A stop 28 is fixedly connected to one side of the hanging rod 23. The stop 28 is slidably connected inside the stop groove 29. The stop groove 29 is located on one side of the track plate 1 and is adjacent to the convex groove 19. When the triangular insert 21 is fully inserted into the triangular slot 24, the stop 28 on the hanging rod 23 will be inserted into the stop groove 29, thereby preventing the limit block 2 from rotating during use.
