Description

Technical Field

[0001] This utility model relates to the field of fan display rack technology, and in particular to a magnetic adjustable fan display rack. Background Technology

[0002] As a traditional handicraft that combines practicality and cultural significance, the way fans are displayed has a significant impact on showcasing their aesthetic appeal, protecting the integrity of the fan surface, and improving display efficiency. Fan display stands, specifically designed to support and display fans, are widely used in museum exhibitions, cultural events, and commercial store displays. A high-quality fan display stand not only needs a stable structure to ensure the fans are not easily tipped over or damaged during display, but also needs to accommodate the installation requirements of fans of different sizes and styles, while also ensuring ease of installation and disassembly for quick setup and adjustment of the display environment.

[0003] In existing technologies, most common fan display stands employ mechanical structures with snap-fit ​​connections or direct bolt fixation. Snap-fit ​​connections typically involve protrusions and grooves on corresponding components of the display stand. External force is applied to press the protrusions into the grooves to achieve the connection. The technical principle mainly relies on the frictional force generated by the elastic deformation of the components themselves to maintain fixation. Direct bolt fixation involves creating through holes at the connection points, passing bolts through the holes, and tightening them with nuts. The locking force between the threads achieves a rigid connection. Some structures also use washers to enhance the stability of the connection.

[0004] However, existing display racks often lack sufficient positioning accuracy, making it difficult to achieve precise alignment between components. This can easily lead to situations where the fan frame and the display rack are not tightly fitted after connection, affecting the aesthetics and structural stability of the display. While bolt fixing provides higher connection strength, it requires repeated adjustments to the component positions to align with the bolt holes during installation. This is not only cumbersome but may also cause uneven stress on the fan frame due to positioning deviations, leading to loosening over time and posing a threat to the stable display of the fan frame. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a magnetic adjustable fan display stand, which aims to improve the problem that the positioning accuracy of existing display stands is usually insufficient, making it difficult to achieve precise alignment between components. This often results in the fan frame not fitting tightly to the display stand after connection, affecting the aesthetics and structural stability of the display.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetically adjustable fan display rack, comprising a frame limiting plate one, a frame limiting plate two attached to the outer wall of the frame limiting plate one, a positioning sleeve fixedly connected inside the frame limiting plate two, the outer wall of the positioning sleeve slidably connected inside the frame limiting plate one, a bearing one fixedly connected to the inner wall of the positioning sleeve, a screw one fixedly connected to the inner wall of the bearing one, a trapezoidal push block threadedly connected to the outer wall of the screw one, the outer wall of the trapezoidal push block slidably connected to the inside of the positioning sleeve, a triangular locking block slidably connected to the outer wall of the trapezoidal push block, a telescopic rod two fixedly connected inside the triangular locking block, a spring two sleeved on the outer wall of the telescopic rod two, and magnetic components provided inside both the frame limiting plate one and the frame limiting plate two;

[0007] The magnetic suction assembly includes a magnetic suction block, which is disposed inside the first frame limiting plate and the second frame limiting plate, and a fan frame is disposed between the first frame limiting plate and the second frame limiting plate.

[0008] Furthermore, a protruding plate is fixedly connected inside the first and second skeleton limiting plates, and a screw rod is threadedly connected inside the protruding plate.

[0009] Furthermore, one end of the screw is rotatably connected to a rotating shaft, and a sliding plate is fixedly connected to the bottom of the rotating shaft.

[0010] Furthermore, the outer wall of the slide plate is slidably connected to the inside of the first protrusion plate, and multiple fixed shafts are fixedly connected to the lower surface of the slide plate.

[0011] Furthermore, the internal thread of the convex plate is connected to a screw rod three, and one end of the screw rod three is fixedly connected to a pressure plate.

[0012] Furthermore, a second convex plate is slidably connected inside the first convex plate, and the second convex plate has multiple mounting holes inside.

[0013] Furthermore, the outer wall of the triangular block is slidably connected inside the positioning sleeve and the skeleton limiting plate.

[0014] Furthermore, both ends of the second spring are fixedly connected to the inside of the triangular block.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, initial precise positioning is achieved through a magnetic block, coupled with a mechanical locking mechanism that uses a screw to drive a trapezoidal push block to move a triangular locking block. The inclined design of the triangular locking block allows for a perfectly fitted and stable connection, ensuring the structural stability of the fan frame after installation. Furthermore, the installation and removal process only requires rotating the screw in both directions, and the return motion of the spring allows for quick completion of the operation, simplifying the installation and disassembly process of the fan frame, improving operational efficiency, and facilitating the replacement and maintenance of the fan frame.

[0017] 2. In this utility model, a stable connection is achieved by precisely engaging the fixed shaft with the mounting hole via screw two, and then screw three drives the pressure plate to further secure the slide plate, enhancing the overall stability after assembly and preventing loosening. Simultaneously, assembly and disassembly are completed by rotating screw one, simplifying operation, reducing manual labor difficulty, ensuring accuracy and consistency in assembly, and improving the assembly quality and reusability of the display rack.

[0024] 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.

[0025] Reference Figures 1-4 An embodiment of this utility model provides a magnetic adjustable fan display rack, including a frame limiting plate 1, a frame limiting plate 2 attached to the outer wall of the frame limiting plate 1, a positioning sleeve 7 fixedly connected inside the frame limiting plate 2, the outer wall of the positioning sleeve 7 slidably connected to the inside of the frame limiting plate 1, a bearing 8 fixedly connected to the inner wall of the positioning sleeve 7, a screw 9 fixedly connected to the inner wall of the bearing 8, a trapezoidal push block 10 threadedly connected to the outer wall of the screw 9, the outer wall of the trapezoidal push block 10 slidably connected to the inside of the positioning sleeve 7, a triangular locking block 11 slidably connected to the outer wall of the trapezoidal push block 10, a telescopic rod 12 fixedly connected inside the triangular locking block 11, a spring 13 sleeved on the outer wall of the telescopic rod 12, and magnetic components provided inside both the frame limiting plate 1 and the frame limiting plate 2.

[0026] The magnetic suction assembly includes a magnetic suction block 4, which is disposed inside the first frame limiting plate 1 and the second frame limiting plate 2. A fan frame 3 is disposed between the first frame limiting plate 1 and the second frame limiting plate 2. The outer wall of the triangular block 11 is slidably connected to the positioning sleeve 7 and the first frame limiting plate 1. Both ends of the second spring 13 are fixedly connected to the inside of the triangular block 11.

[0027] Specifically, when using this display rack, first insert the positioning sleeve 7 on the outer wall of the frame limiting plate 2 into the frame limiting plate 1, and position it with the magnetic block 4; then drive the handle at one end of the screw 9, which, with the help of the bearing 8, drives the screw 9 to rotate within the positioning sleeve 7. Due to the threaded relationship between the screw 9 and the trapezoidal push block 10, the trapezoidal push block 10 slides within the positioning sleeve 7 as the screw 9 rotates. Its two inclined surfaces push the two triangular locking blocks 11 to slide within the positioning sleeve 7 and the frame limiting plate 1, thus connecting the two and simultaneously stretching the spring 2 13; when the triangular locking blocks 11 move into the frame limiting plate 1, the distance between them gradually decreases with the help of their own inclined surfaces, eventually fitting completely. When disassembling, rotate the screw 9 in the opposite direction, and the spring 2 13 rebounds, pulling the triangular locking blocks 11 back into the positioning sleeve 7, completing the assembly and disassembly of the fan frame 3 between the frame limiting plate 1 and the frame limiting plate 2.

[0028] Reference Figures 1-4The frame limiting plate 1 and the frame limiting plate 2 are internally fixedly connected to a protruding plate 14. The protruding plate 14 is internally threadedly connected to a screw 2 15. One end of the screw 2 15 is rotatably connected to a rotating shaft 16. The bottom of the rotating shaft 16 is fixedly connected to a sliding plate 17. The outer wall of the sliding plate 17 is slidably connected to the inside of the protruding plate 14. The lower surface of the sliding plate 17 is fixedly connected to multiple fixed shafts 18. The protruding plate 14 is internally threadedly connected to a screw 3 19. One end of the screw 3 19 is fixedly connected to a pressure plate 20. The protruding plate 14 is internally slidably connected to a protruding plate 2 6. The protruding plate 2 6 has multiple mounting holes 5 inside.

[0029] Specifically, when assembling the first frame limiting plate 1, it is first inserted into the second frame limiting plate 2 with the protruding plates 14 and 6 inside, offset from each other. The pre-set mounting hole 5 inside the protruding plate 6 moves with the insertion until it is aligned with the bottom of the fixing shaft 18. The second drive screw 15 rotates inside the protruding plate 14, which, together with the rotating shaft 16, pushes the slide plate 17 to move, so that the fixing shaft 18 enters the mounting hole 5, achieving a stable connection between the two frame limiting plates 1. After connection, the third drive screw 19 rotates inside the protruding plate 14, and the pressure plate 20 moves with it and fits tightly against the slide plate 17, further fixing the slide plate 17. When disassembling the first frame limiting plate 1, the connection can be released by rotating the second screw 15 and the third screw 19 in the opposite direction, completing the splicing operation.

[0030] Working principle: When using this display rack, firstly, the positioning sleeve 7 on the outer wall of the frame limiting plate 2 is inserted into the frame limiting plate 1 and positioned in conjunction with the magnetic block 4. Then, the handle at one end of the drive screw 9, in conjunction with the bearing 8, drives the screw 9 to rotate inside the positioning sleeve 7. Due to the threaded relationship between the screw 9 and the trapezoidal push block 10, the trapezoidal push block 10 slides inside the positioning sleeve 7 as the screw 9 rotates. This, through the inclined surfaces on both sides of the trapezoidal push block 10, pushes the two triangular locking blocks 11 to slide inside the positioning sleeve 7 and the frame limiting plate 1, thereby achieving frame positioning. The connection between the positioning plate 1 and the frame limiting plate 2 causes the spring 2 13 to be stretched. When the triangular block 11 moves into the interior of the frame limiting plate 1, the distance between the frame limiting plate 1 and the frame limiting plate 2 gradually decreases due to the inclined surface of the triangular block 11, and finally achieves a completely fitted connection. When disassembling, it is only necessary to rotate the screw 9 in the opposite direction. At this time, the spring 2 13 is no longer under force and rebounds, thereby pulling the triangular block 11 back into the positioning sleeve 7, realizing the installation and disassembly of the fan frame 3 between the frame limiting plate 1 and the frame limiting plate 2.

[0031] Furthermore, firstly, the protruding plates 14 and 6 inside the frame limiting plate 1 and frame limiting plate 2 are interlocked. The pre-set mounting hole 5 inside the protruding plate 26 will move with the interlocking action until it is accurately aligned below the fixed shaft 18. Next, the drive screw 2 15 starts to rotate inside the protruding plate 14. As the screw 2 15 rotates, it will cooperate with the rotating shaft 16 to push the slide plate 17 to move inside the protruding plate 14, so that the fixed shaft 18 accurately moves into the mounting hole 5, thereby achieving a stable connection between the two frame limiting plates 1. After the frame limiting plates 1 are connected, the drive screw 3 19 continues to rotate inside the protruding plate 14. The pressure plate 20 will move with the rotation of the screw 3 19 and finally fit tightly against the slide plate 17, thereby further fixing the slide plate 17. When it is necessary to disassemble the frame limiting plate 1, simply rotate the screw 2 15 and the screw 3 19 in the opposite direction to easily release the connection between them, thus realizing the splicing of the frame limiting plate 1.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
