Technical Field
[0001] This utility model relates to the technical field of angle positioning devices, specifically a dual-axis rotating display panel angle positioning device. Background Technology
[0002] A display board is a sheet-like material used to display information, posters, advertisements, etc. It is commonly used in public places, commercial displays, conferences, and exhibitions to help convey information and attract attention. Display boards serve as a medium for information presentation, product display, or event promotion. Their design and application scenarios vary depending on the materials, structure, and function. Through diverse materials and designs, display boards can meet the information transmission needs of different scenarios, combining practicality and aesthetics. Display boards are widely used in various exhibitions such as art auctions, painting exhibitions, fine art exhibitions, photography exhibitions, antique and luxury goods exhibitions, and conference exhibitions. Their design quality is crucial for attracting audiences, promoting products, and stimulating consumption. Common types include KT board, PVC foam board, high-density fiberboard, and acrylic board. A dual-axis rotating display board is a type of display board that allows the angle to be adjusted according to actual needs.
[0003] Existing dual-axis rotating display panels typically fix their angle by using the friction of a damping shaft. This method is not very effective at fixing the display panel angle and is prone to displacement under external forces, reducing the device's practicality and making it inconvenient to use. Therefore, we propose a dual-axis rotating display panel angle positioning device. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a dual-axis rotating display panel angle positioning device. This device solves the problem that when adjusting the placement angle of a dual-axis rotating display panel, the angle is usually fixed by the friction of the damping shaft, which has a relatively poor fixing effect on the display panel angle and is prone to displacement when subjected to external forces, thus reducing the practical effectiveness of the device.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A dual-axis rotating display panel angle positioning device includes a fixed frame, with rotating shafts symmetrically rotatably connected inside the fixed frame, and a display panel body fixedly connected between the two rotating shafts. A fixed frame is fixedly connected to one side of the fixed frame, and limiting slide rods are fixedly connected at equal intervals to the inner wall of the fixed frame. A sliding frame is slidably connected to the outer side of the limiting slide rods, and a locking tooth is fixedly connected to one side of the sliding frame. A limiting tooth ring that cooperates with the locking tooth is fixedly connected to the outer side of one of the rotating shafts. An adjustment mechanism that cooperates with the sliding frame is provided inside the fixed frame.
[0007] The adjustment mechanism includes a connecting shaft, which is rotatably connected inside the fixed frame. One end of the connecting shaft is fixedly connected to a rotating seat, and the rotating seat has equidistant connecting grooves inside. A connecting block that mates with the connecting grooves is fixedly connected to one side of the sliding frame.
[0008] In a preferred embodiment, a fixing block is fixedly connected to the inner wall of the fixing frame, a worm gear is rotatably connected between the fixing block and the fixing frame, and a worm wheel that cooperates with the worm gear is fixedly connected to the outer side of the connecting shaft.
[0009] The technical effect of adopting the above-mentioned further solution is that the worm drives the connecting shaft to rotate through the worm wheel, and the connecting shaft drives the rotating seat to rotate, so that the connecting groove and the connecting block can be used in conjunction.
[0010] In a preferred embodiment, an operating knob is fixedly connected to the end of the worm gear away from the fixed block, and anti-slip protrusions are fixedly connected at equal intervals to the outer side of the operating knob.
[0011] The technical effect of adopting the above-mentioned further solution is that the anti-slip protrusions can increase the friction, prevent the operating knob from slipping during rotation, facilitate the rotation of the operating knob, and drive the worm gear to rotate.
[0012] In a preferred embodiment, a limiting block is fixedly connected to the end of the limiting slide rod away from the fixed frame, and mounting holes are provided at equal intervals at the bottom of the fixed frame.
[0013] The technical effects of adopting the above-mentioned further solution are as follows: the movement of the sliding frame can be limited by the setting of the limiting block and the limiting slide rod, preventing the sliding frame from deviating during the movement, thus enhancing the stability of the sliding frame during the movement. The setting of multiple sets of mounting holes facilitates the installation and fixation of the fixed frame.
[0014] In a preferred embodiment, a protective frame is fixedly connected to one side of the fixed frame, and a limiting groove is symmetrically formed inside the protective frame, with a protective cover slidably connected inside the limiting groove.
[0015] The technical effects of adopting the above-mentioned further solution are as follows: the protective frame and protective cover can shield and protect the operating knob when not in use, preventing accidental contact with the operating knob and causing misoperation; the two sets of limit slides can limit the movement of the protective cover, preventing the protective cover from shifting during movement and enhancing the stability of the protective cover during movement.
[0016] In a preferred embodiment, magnets are fixedly connected to one side of the protective cover and the inner wall of the protective frame.
[0017] The technical effect of adopting the above-mentioned further solution is that by setting up two sets of magnets, the magnetic attraction of the magnets can be used to fix the position of the protective cover to a certain extent when it is closed.
[0018] This invention provides a dual-axis rotating display panel angle positioning device. Compared with the prior art, it has the following advantages:
[0019] 1.

[0034] 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.
[0035] Please see Figures 1-7 This utility model provides a technical solution:
[0036] A dual-axis rotating display panel angle positioning device includes a fixed frame 1. A rotating shaft 41 is symmetrically rotatably connected inside the fixed frame 1. A display panel body 4 is fixedly connected between the two rotating shafts 41. A fixed frame 3 is fixedly connected to one side of the fixed frame 1. Limiting slide rods 34 are fixedly connected at equal intervals to the inner wall of the fixed frame 3. A sliding frame 31 is slidably connected to the outer side of the limiting slide rods 34. A locking tooth 32 is fixedly connected to one side of the sliding frame 31. A limiting tooth ring 42 that cooperates with the locking tooth 32 is fixedly connected to the outer side of one of the rotating shafts 41. An adjustment mechanism 5 that cooperates with the sliding frame 31 is provided inside the fixed frame 3. The adjustment mechanism 5 includes a connecting shaft 53. The connecting shaft 53 is rotatably connected inside the fixed frame 3. A rotating seat 51 is fixedly connected to one end of the connecting shaft 53. A connecting groove 52 is equidistantly opened inside the rotating seat 51. A connecting block 35 that cooperates with the connecting groove 52 is fixedly connected to one side of the sliding frame 31.
[0037] In this solution, when the angle of the display panel body 4 needs to be adjusted during use, the connecting shaft 53 drives the rotating seat 51 to rotate, so that the connecting groove 52 and the connecting block 35 cooperate. During the rotation of the rotating seat 51, the connecting block 35 is squeezed and moved, and the connecting block 35 drives the sliding frame 31 to move. The sliding frame 31 drives the locking tooth 32 to move, so that the locking tooth 32 moves away from the limiting tooth ring 42, releasing the locking state of the rotating shaft 41. Thus, the angle of the display panel body 4 can be adjusted during display. After the adjustment is completed, the connecting shaft 53 is rotated in the opposite direction. The reverse rotation of the connecting shaft 53 drives the sliding frame 31 to move and reset. The sliding frame 31 drives the locking tooth 32 to move, so that the locking tooth 32 moves and fits tightly against the limiting tooth ring 42, thereby locking the position of the rotating shaft 41 and preventing the angle of the display panel body 4 from shifting, thus enhancing the stability during display.
[0038] like Figure 3 , Figure 4 and Figure 5 As shown: In this scheme, a fixing block 55 is fixedly connected to the inner wall of the fixing frame 3, and a worm gear 54 is rotatably connected between the fixing block 55 and the fixing frame 3. A worm wheel 56 that works with the worm gear 54 is fixedly connected to the outer side of the connecting shaft 53. An operating knob 57 is fixedly connected to the end of the worm gear 54 away from the fixing block 55, and anti-slip protrusions 58 are fixedly connected at equal intervals to the outer side of the operating knob 57.
[0039] In this design, the anti-slip protrusions 58 increase friction and prevent the operating knob 57 from slipping during rotation, making it easier to rotate. The operating knob 57 drives the worm gear 54 to rotate, which in turn drives the connecting shaft 53 to rotate via the worm wheel 56. The connecting shaft 53 then drives the rotating seat 51 to rotate, allowing the connecting groove 52 and the connecting block 35 to work together.
[0040] like Figures 1-4 As shown: In this scheme, the end of the limiting slide bar 34 away from the fixed frame 3 is fixedly connected to the limiting block 33, and the bottom of the fixed frame 1 is provided with mounting holes at equal intervals.
[0041] In this scheme, the movement of the sliding frame 31 can be limited by the setting of the limiting block 33 and the limiting slide bar 34, so as to prevent the sliding frame 31 from deviating during the movement and enhance the stability of the sliding frame 31 during the movement. The setting of multiple sets of mounting holes facilitates the installation and fixing of the fixing frame 1.
[0042] like Figures 1-7As shown: In this scheme, a protective frame 2 is fixedly connected to one side of the fixed frame 3. A limiting groove 21 is symmetrically opened inside the protective frame 2. A protective cover 22 is slidably connected inside the limiting groove 21. A magnet 23 is fixedly connected to one side of the protective cover 22 and the inner wall of the protective frame 2.
[0043] In this design, the protective frame 2 and the protective cover 22 can shield and protect the operating knob 57 when not in use, preventing accidental operation caused by touching the operating knob 57. The two sets of limiting slide grooves 21 can limit the movement of the protective cover 22, preventing the protective cover 22 from shifting during movement and enhancing the stability of the protective cover 22 during movement. The two sets of magnets 23 can be used to fix the position of the protective cover 22 when it is closed by utilizing the attraction of the magnets 23.
[0044] Working principle:
[0045] The device is equipped with a fixed frame 1, a protective frame 2, and an adjustment mechanism 5. When it is necessary to adjust the angle of the display panel body 4, the protective cover 22 is pushed and opened, thereby rotating the operating knob 57. The operating knob 57 drives the worm wheel 56 to rotate via the worm gear 54. The worm wheel 56 drives the rotating seat 51 to rotate via the connecting shaft 53, so that the connecting groove 52 and the connecting block 35 cooperate. During the rotation of the rotating seat 51, the connecting block 35 is squeezed and driven to move. The connecting block 35 drives the sliding frame 31 to move. The movement of the sliding frame 31 is limited by the setting of the limiting block 33 and the limiting slide rod 34 to prevent the sliding frame 31 from deviating during the movement. The sliding frame 31 drives the locking tooth 32 to move, so that the locking tooth 32 moves away from the limiting tooth ring 42, releasing the locking state of the rotating shaft 41, thereby allowing the angle of the display panel body 4 to be adjusted.
[0046] After adjustment, rotate the operation knob 57 in the opposite direction to move and reset the sliding frame 31. The sliding frame 31 moves the locking tooth 32, causing the locking tooth 32 to move and fit tightly against the limiting tooth ring 42, thereby locking the position of the rotating shaft 41 and preventing the angle of the display panel body 4 from shifting, thus enhancing the stability during display.
[0047] After adjustment, close the protective cover 22 to shield the operating knob 57, preventing accidental operation and facilitating use.
[0048] The protective frame 2 and the protective cover 22 can protect the operating knob 57 when it is not in use, preventing accidental operation caused by touching the operating knob 57.
[0049] The movement of the protective cover 22 can be limited by the setting of two sets of limiting slide grooves 21, preventing the protective cover 22 from shifting during movement and enhancing the stability of the protective cover 22 during movement. The position of the protective cover 22 can be fixed to a certain extent by the adsorption property of the magnets 23 when the protective cover 22 is closed.
