Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4This illustration shows an embodiment of the present invention providing a windproof frame for a display screen, which is installed on an LED display screen housing 1. The windproof frame includes a main support rod 2, a movable part 3, a longitudinal hand-tightening fastening sleeve, a rotating connection assembly, and a mounting base 4. One end of the movable part 3 is detachably connected to the main support rod 2, and the other end is connected to the mounting base 4 through the rotating connection assembly. The mounting base 4 is fixed to the housing frame of the LED display screen housing 1. The longitudinal hand-tightening fastening sleeve includes a first threaded part 5 and a second threaded part 6. The first threaded part 5 is coaxially connected to the upper end of the main support rod 2, and the second threaded part 6 is coaxially connected to the lower end of the main support rod 2. The first threaded part 5 and the second threaded part 6 of another display screen windproof frame are locked together by rotating and engaging to achieve locking of two adjacent longitudinally arranged display screen windproof frames.

[0024] Specifically, the first threaded component 5 has an internal thread and a concave edge 7 at the top, and the second threaded component 6 has an external thread and a protrusion 8 that matches the concave edge 7. When the first threaded component 5 is rotated, the first threaded component 5 and the second threaded component 6 of the other display screen windproof frame are connected by the internal thread and the external thread, and the protrusion 8 stops and locks when it is screwed into the concave edge 7.

[0025] Specifically, the rotating connection assembly includes a rotating shaft 9, the mounting base 4 includes a rotating shaft through hole, and the movable part 3 is rotatably connected to the rotating shaft through hole via the rotating shaft 9.

[0026] More specifically, the rotating connection assembly further includes a locking rod 10, an elastic element 11, a handle 12, and a pressing element 13. The rotating shaft 9 is a hollow shaft structure. The locking rod 10 is movably mounted in the inner cavity of the rotating shaft 9. The handle 12 is fixed to the rotating shaft 9. The pressing element 13 is fixed to the upper part of the locking rod 10. One end of the elastic element 11 acts on the pressing element 13, and the other end acts on the upper part of the rotating shaft 9.

[0027] More specifically, the rotating connection assembly also includes a glass bead 14. The lower part of the rotating shaft 9 is provided with a glass bead hole 15 for installing the glass bead 14. One side of the glass bead 14 abuts against the bottom of the locking rod 10, and the other side protrudes from the outer peripheral surface of the rotating shaft 9. Near the bottom of the locking rod 10, there is a coaxial stepped shaft section 16. The shaft diameter of the stepped shaft section 16 is smaller than the rod diameter of the locking rod 10 to provide space for the glass bead 14 to retract. A guide cone surface 17 is provided at the locking rod 10 where it connects to the lower part of the stepped shaft section 16, so that when the locking rod 10 moves down, the glass bead 14 can move along the guide cone surface 17 and completely retract into the glass bead hole 15.

[0028] In some specific embodiments, the rotating shaft 9 limits the end of the movable part 3 or the end of the secondary support assembly by means of its upper shoulder and the glass beads 14 protruding from the outer periphery of the rotating shaft 9. To disassemble the rotating connection assembly, the pressing member 13 needs to be pressed down. The pressing member 13 drives the locking rod 10 to move down. When the locking rod 10 moves down to the point where the glass bead hole 15 of the rotating shaft 9 aligns with the stepped shaft section 16 of the locking rod 10, the handle 12 is lifted. The handle 12 drives the rotating shaft 9 to move up as a whole. At this time, the glass beads located outside the rotating shaft 9 are locked. When the bead surface is compressed, the glass bead 14 moves axially along the glass bead hole 15 until it contacts the stepped shaft section 16. At this time, the glass bead 14 does not protrude from the surface of the rotating shaft 9, thus the limiting effect of the rotating shaft 9 is released, and the rotating shaft 9 can be directly pulled upward to complete the disassembly. In another specific embodiment, the stepped shaft section 16 can be replaced with an arc-shaped groove. After the locking rod 10 moves down relative to the rotating shaft 9, the groove opening of the arc-shaped groove can be aligned with the glass bead hole 15. The groove surface shape of the arc-shaped groove is preferably a shape that matches the shape of the glass bead 14.

[0029] Specifically, the display screen windproof frame further includes a first auxiliary support assembly 18, a second auxiliary support assembly 19, and a third auxiliary support assembly 20. The first auxiliary support assembly 18 is located on the left side of the main support rod 2 and is connected to the movable part 3 and the mounting base 4 located on the left side of the main support rod 2. The second auxiliary support assembly 19 and the third auxiliary support assembly 20 are located on the right side of the main support rod 2 and are connected to the movable part 3 and the mounting base 4 located on the right side of the main support rod 2.

[0030] More specifically, the first auxiliary support component 18 has a Y-shaped structure, and includes a vertical portion 21 and two oblique portions 22 connected to the vertical portion 21 and symmetrically arranged along the vertical portion 21. The second auxiliary support component 19 and the third auxiliary support component 20 are combined to form a Y-shaped structure, and both the second auxiliary support component 19 and the third auxiliary support component 20 include a vertical portion 21 and an oblique portion 22 connected to the vertical portion 21.

[0031] In some specific embodiments, the secondary support component of the Y-shaped bifurcated structure is connected to the movable part 3 and the mounting base 4. When the wind force acts on the display screen, the Y-shaped structure decomposes the horizontal thrust into multiple axial components. The components are transmitted to the main support rod 2 and the box frame through the movable part 3 and the mounting base 4, respectively. This design can effectively disperse the force of the wind on the display screen, thereby avoiding excessive local pressure that could cause the windproof frame structure to become unbalanced and twisted or damaged.

[0032] More specifically, the inclined portion 22 is fixed to the middle of the movable member 3, and the vertical portion 21 is rotatably connected to the mounting base 4.

[0033] More specifically, the vertical portion 21 of the second auxiliary support component 19 is independent of the vertical portion 21 of the third auxiliary support component 20, and there is a predetermined distance between the facing surfaces of the vertical portions 21 of the second auxiliary support component 19 and the vertical portions 21 of the third auxiliary support component 20.

[0034] In some specific embodiments, a pin is provided at the end of the movable part 3 connected to the second auxiliary support assembly 19 and the third auxiliary support assembly 20, and two locking holes are provided at the upper and lower ends of the main support rod 2 corresponding to the pins. The windproof frame is locked by inserting the pins into the locking holes. The independence of the second auxiliary support assembly 19 and the third auxiliary support assembly 20 can improve the alignment accuracy of the pins of the movable parts 3 connected to them and the locking holes of the main support rod 2. It can be understood that it is easier to align a single pin with a corresponding locking hole than to align two pins with two locking holes at once. In addition, when unlocking the pins and locking holes, unlocking a single pin with a corresponding locking hole is obviously easier and more convenient than unlocking two pins with two locking holes at once. In the later maintenance, the independence of the second auxiliary support assembly 19 and the third auxiliary support assembly 20 can also reduce the maintenance difficulty and help reduce maintenance costs. More specifically, the vertical portions 21 of the second auxiliary support assembly 19 and the third auxiliary support assembly 20 are rotatably connected to the mounting base 4 via a rotatable connection assembly, and the lengths of the rotating shaft 9 and the locking rod 10 are adaptively increased to connect the vertical portions 21 of the second auxiliary support assembly 19 and the third auxiliary support assembly 20 in series.

[0035] An LED display cabinet includes a left cabinet frame 23 and a right cabinet frame 24, which are respectively connected to the windproof frame of the display screen.

[0036] In summary, this display screen windproof frame utilizes a longitudinal hand-tightening fastening assembly design, employing a screw-in structure between the first threaded component 5 and the second threaded component 6 to achieve rapid longitudinal docking and locking of two windproof frames. The rotating connection component of this display screen windproof frame uses a glass ball 14 in conjunction with a locking rod 10. By pressing down on the pressing component 13 and lifting the handle 12, the glass ball 14 moves axially along the glass ball hole 15, allowing the rotating shaft 9 to be pulled out with a single click, making it convenient to use. This display screen windproof frame also employs a Y-shaped secondary support component. This bifurcated structure evenly distributes the force on the display screen, avoiding excessive local pressure at a single support point and enhancing the stability of the windproof frame.

[0037] It should be noted that this utility model is not limited to the above-described embodiments. Based on the inventive spirit of this utility model, those skilled in the art can make other changes, and these changes made based on the inventive spirit of this utility model should be included within the scope of protection claimed by this utility model.
