Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display screen protection, in particular to an anti-collision protection device for a display screen. Background Art
[0002] The edge of the display screen is a relatively fragile part. Without corner guards, it is vulnerable to collisions, impacts, etc., resulting in wear, scratches or breakage.
[0003] Most of the existing corner guards for display screens exist independently. They are in a triangular structure or an L-shaped structure and are sleeved on the corners of the display screen. Due to the lack of a limiting function, they are prone to falling off during transportation, installation or use. Some use a sheath to connect the corner guards together, but due to the fixed size, the applicable range is relatively narrow, and the distance between the corner guards cannot be adjusted according to the size of the display screen. Summary of the Utility Model
[0004] I. Technical Problems to be Solved
[0005] The technical problems to be solved by the utility model are that the distance between the corner guards cannot be adjusted according to the size of the display screen, and a single corner guard cannot be stably connected.
[0006] II. Technical Solutions
[0007] To solve the above technical problems, the technical solution provided by the utility model is: an anti-collision protection device for a display screen, including corner guards and a mounting base. On both sides of the top and bottom of the mounting base, first hinge rods are respectively hinged. The other end of the first hinge rod is hinged with a second hinge rod through a hinge seat. A limiting component for limiting the hinging angle of the first hinge rod and the second hinge rod is connected to the hinge seat. The other end of the second hinge rod is hinged with the corner guard. A rotating component for driving the telescopic components on both sides to rotate relatively synchronously and a positioning component for positioning the rotating component are connected in the mounting base.
[0008] Further, the rotating component includes a cavity connected in the mounting base. A connecting shaft is connected in the cavity. First bevel gears are respectively rotatably connected on both sides of the connecting shaft. Opposite the first bevel gears, the first hinge rods on both sides are respectively connected. A driving rod is rotatably connected to the mounting base. One end of the driving rod is connected with a second bevel gear in the cavity. The second bevel gear meshes with the first bevel gear. The other end of the driving rod penetrates through the mounting base and is connected with a knob at the end. The knob drives the second bevel gear to rotate through the driving rod. The second bevel gear drives the first bevel gears on both sides through meshing with the first bevel gear. The first bevel gear drives the first hinge rod to rotate relatively around the connecting shaft, so as to facilitate adjusting the width between the corner guards.
[0009] Further, the positioning component includes several grooves circumferentially connected to the end face of the second bevel gear. A limit pin that cooperates with the grooves is slidably connected to the mounting base. When the limit pin is pulled out, the second bevel gear is no longer limited and can rotate. After the angle between the second bevel gear and the first hinge rod is adjusted, the limit pin can be engaged with the corresponding groove to limit the second bevel gear.
[0010] Further, through grooves are respectively connected to both sides of the cavity of the mounting base. The through grooves are matched with the thickness of the first hinge rod, facilitating the free rotation of the first hinge rod for the adjustment of the rotating component and avoiding interference with the rotating component.
[0011] Further, the hinge seat includes an outer cylinder connected to the end of the second hinge rod. An inner shaft is rotatably connected inside the outer cylinder. A fixing rod is connected to the inner shaft. Through holes that cooperate with the fixing rod are circumferentially connected to the outer cylinder. The fixing rod passes through the through holes and is connected to the first hinge rod at the end. The inner shaft is hinged to the outer cylinder through the sliding of the fixing rod in the through holes.
[0012] Further, the limiting component includes a sliding rod that slidably penetrates the inner shaft. A pressing plate is connected to the other end of the sliding rod. A spring is sleeved on the sliding rod between the pressing plate and the outer cylinder. Several limiting beads are evenly distributed circumferentially on the inner shaft. Limiting grooves are oppositely connected to the outer cylinder. The limiting grooves cooperate with the limiting beads. A ring groove is connected to the sliding rod. In the natural state, the spring is stretched. At this time, the circumferential wall of the sliding rod jacks up the limiting beads, so that the limiting beads penetrate the inner shaft and cooperate with the limiting grooves for limiting. When the angle needs to be adjusted, by pressing the pressing plate, the pressing plate drives the sliding rod to slide downward until the ring groove is opposite to the limiting beads. The inner shaft is driven to rotate through the fixing rod, and the balls penetrate the inner shaft and cooperate with the ring groove as the inner shaft rotates, enabling relative rotation adjustment between the outer cylinder and the inner shaft.
[0013] III. Beneficial Effects
[0014] The advantages of the present utility model compared with the prior art are as follows:
[0015] Through the cooperative setting of the corner guard, mounting base, first hinge rod, second hinge rod, limiting component, rotating component, and positioning component, it is convenient to adjust the distance between the corner guard and the mounting base through the first hinge rod and the second hinge rod. With the setting of the rotating component and the positioning component, it can be adapted to display screens with different length-width ratios, facilitating the stable wrapping of the four corners of various display screens, preventing collisions, and improving the anti-collision practicality.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Combined with the attached Figure 1 and Figure 4 , an anti-collision protection device for a display screen includes a corner guard 1 and a mounting seat 2. The top and bottom sides of the mounting seat 2 are respectively hinged with first hinge rods 3. The other ends of the first hinge rods 3 are hinged with second hinge rods 4 through 23. The hinge seat 23 includes an outer cylinder 13 connected to the end of the second hinge rod 4. An inner shaft 14 is rotatably connected in the outer cylinder 13. A fixed rod 15 is connected to the inner shaft 14. A through hole 16 matching with the fixed rod 15 is circumferentially connected to the outer cylinder 13. The fixed rod 15 passes through the through hole 16 and is connected to the first hinge rod 3 at the end; a limiting component for limiting the hinging angle of the first hinge rod 3 and the second hinge rod 4 is connected to the hinge seat 23. The other end of the second hinge rod 4 is hinged with the corner guard 1. The limiting component includes a slide rod 17 slidably penetrating through the inner shaft 14. The other end of the slide rod 17 is connected with a pressing plate 18. A spring 19 is sleeved on the slide rod 17 between the pressing plate 18 and the outer cylinder 13. A plurality of limit beads 20 are circumferentially and evenly arranged on the inner shaft 14. Limit grooves 21 are oppositely connected to the outer cylinder 13. The limit grooves 21 cooperate with the limit beads 20. A ring groove 22 is connected to the slide rod 17;
[0023] The co-planar arrangement of the same-side end faces of the mounting base 2 and the corner guard 1 ensures that regardless of how the hinge angles of the first hinge rod 3 and the second hinge rod 4 change, the same-side end faces of the mounting base 2 and the corner guard 1 always abut against the back of the display screen. By adjusting the distance between the corner guard 1 and the mounting base 2 through the first hinge rod 3 and the second hinge rod 4 in the above structure, and then limiting the hinge seat 23 through the limiting component, it is convenient to lock the hinge angles of the first hinge rod 3 and the second hinge rod 4.
[0024] Combined with the attached Figure 1 , Figure 2 and Figure 3 , a rotating component capable of driving the synchronous relative rotation of the telescopic components on both sides and a positioning component capable of positioning the rotating component are connected and provided inside the mounting base 2. The rotating component includes a cavity connected inside the mounting base 2. A connecting shaft 5 is connected and provided inside the cavity. First bevel gears 6 are respectively rotatably connected to both sides of the connecting shaft 5. Opposite the first bevel gears 6, the first hinge rods 3 are respectively connected to both sides. The mounting base 2 is respectively connected and provided with through grooves 12 on both sides of the cavity. The through grooves 12 are in thickness fit with the first hinge rods 3. A driving rod 7 is rotatably connected to the mounting base 2. One end of the driving rod 7 is connected and provided with a second bevel gear 8 inside the cavity. The second bevel gear 8 meshes with the first bevel gear 6. The other end of the driving rod 7 penetrates through the mounting base 2 and a knob 9 is connected to the end. The positioning component includes a plurality of grooves 10 connected circumferentially to the end face of the second bevel gear 8. A limiting pin 11 that cooperates with the grooves 10 is slidably connected to the mounting base 2.
[0025] The cooperation of the rotating component and the positioning component can make it adapt to display screens with different aspect ratios, facilitate the stable wrapping of the four corners of various display screens, prevent collisions, and improve the anti-collision practicality.
[0026] The specific usage method is as follows:
[0027] When it is necessary to adjust the included angle between adjacent first hinge rods 3, the limiting pin 11 can be pulled out. The second bevel gear 8 is no longer limited and can rotate. At this time, the knob 9 can be driven. The knob 9 drives the second bevel gear 8 to rotate through the driving rod 7. The second bevel gear 8 drives the first bevel gears 6 on both sides through meshing with the first bevel gear 6. The first bevel gears 6 drive the first hinge rods 3 to rotate relative to each other with the connecting shaft 5 as the axis, thereby facilitating the adjustment of the width between the corner guards 1. Through the thickness fit of the through grooves 12 and the first hinge rods 3, it is convenient for the first hinge rods 3 to rotate freely for the adjustment of the rotating component, avoiding interference with the rotating component. After the angle between the first hinge rods 3 driven by the second bevel gear 8 is adjusted, the limiting pin 11 can be matched with the corresponding grooves 10 to limit the second bevel gear 8.
[0028] Then, when it is necessary to adjust the distance between the corner guard 1 and the mounting base 2, by pressing the pressing plate 18, the pressing plate 18 drives the sliding rod 17 to slide downward. At this time, the spring 19 is compressed and stores energy until the annular groove 22 is aligned with the limiting bead 20. The inner shaft 14 is driven to rotate by the fixing rod 15, and the rolling beads penetrate the inner shaft 14 and cooperate with the annular groove 22 as the inner shaft 14 rotates, so that the outer cylinder 13 and the inner shaft 14 can rotate relative to each other for adjustment. The telescopic of the corner guard 1 is adjusted by adjusting the hinge angle between the first hinge rod 3 and the second hinge rod 4, so that the side walls of the triangular corner guard 1 can respectively cooperate with the four corners of the display screen. Then, the pressing plate 18 is released, and the spring 19 returns and stretches. At this time, the circumferential wall of the sliding rod 17 jacks up the limiting bead 20, so that the limiting bead 20 penetrates the inner shaft 14 and cooperates with the limiting groove 21 for limiting.
