Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a step-adjustable angle sports field fence screen. Background Technology

[0002] An LED display screen is a flat panel display composed of small LED module panels. It is used to display various information such as text, images, videos, and recorded signals. During sports competitions, many LED displays are often set up around the stadium to form a stadium fence screen. They can be used to show highlights and scores to the audience, or for investors to display advertisements.

[0003] Currently, stadium fence screens can only be installed vertically and cannot be adjusted in angle according to usage needs. Therefore, a step-adjustable angle stadium fence screen is designed, which can be adjusted to multiple angles according to the needs of the site to adapt to different viewing angles and has strong applicability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a step-adjustable angle sports field fence screen. By setting an adjustment mechanism at the bottom of the box, the screen can be adjusted to different tilt angles to obtain a better viewing effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable-angle ball court fence screen with a foot pedal includes a housing. A module is provided at the front end of the housing, and an adjustment mechanism is fixedly connected to the rear end of the bottom of the housing. The adjustment mechanism includes a balance adjustment component, a U-shaped mounting base is fixed at the upper end of the balance adjustment component, a fixing rod is horizontally fixed at the lower front end of the mounting base, a rotating connecting rod is horizontally provided at the upper front end of the mounting base, an L-shaped sliding groove is symmetrically opened at the upper rear end of the mounting base, a limiting rod is horizontally provided in the L-shaped sliding groove, a tension spring is connected between the fixing rod and the limiting rod, a foot pedal connector is provided on the outer side of the rear end of the mounting base, a rotating connecting hole a is symmetrically opened on both sides of the front end of the foot pedal connector, the limiting rod passes through the rotating connecting hole a, a U-shaped limiting component is sleeved on the upper end of the mounting base, a rotating connecting hole b is horizontally opened at the lower rear end of the limiting component, the rotating connecting rod passes through the rotating connecting hole b, a plurality of limiting grooves are provided at the rear end of the limiting component, the limiting rod can be snapped into the limiting grooves, a fixing plate is fixedly connected to the front end of the limiting component, and the fixing plate is fixedly connected to the middle of the lower end of the housing.

[0006] In use, stepping on the connecting piece causes it to move backward, moving the limiting rod backward within the L-shaped groove. The tension spring is then stretched. At this point, rotating the housing backward around the connecting rod's axis allows the limiting rod to engage with the corresponding limiting groove at the desired angle. Specifically, when the limiting rod aligns with the selected limiting groove, releasing the connecting piece allows the tension spring to pull the limiting rod forward into the limiting groove, thus fixing the housing in place. The limiting grooves correspond to multiple adjustment angles, including a 0° groove at the top of the limiting piece (indicating the adjustment mechanism is parallel to the housing), and a 45° groove at the middle of the rear end of the limiting piece. Further downwards, corresponding angles of 70°, 80°, and 90° are also provided. Of course, more limiting grooves corresponding to different angles can be provided as needed.

[0007] Preferably, the balance adjustment assembly includes a hollow base plate with a telescopic plate inserted inside. A groove is formed at the upper end of the base plate, and a fixing bolt is installed within the groove. The lower end of the fixing bolt can press downwards against the inner wall of the lower end of the telescopic plate, causing the lower wall of the telescopic plate to abut and lock against the inner wall of the lower end of the base plate. By loosening the fixing bolt, the telescopic plate can be extended forward, and then the fixing bolt can be tightened, effectively preventing the display screen from tipping over when its center of gravity shifts during angle adjustment.

[0008] Preferably, the rear side walls of the mounting base are curved, and guide grooves are provided on both sides of the front end of the foot-operated connector. The two sides of the mounting base are embedded in the guide grooves, and the inner wall of the guide groove abuts against the upper part of the curved surface. When the foot is pressed down on the foot-operated connector, the foot-operated connector slides down along the curved surface. As the foot-operated connector moves, it moves backward, causing the limit rod to move backward, releasing the locking relationship between the limit rod and the limit groove. The guide groove ensures that the foot-operated connector moves along the curved surface within a preset stroke.

[0009] Preferably, the mounting base has a reinforcing rib fixed inside, which effectively increases the strength of the mounting base. A sealing plate is fixedly connected to the opening at the upper end of the mounting base, which effectively strengthens the upper end of the mounting base and effectively prevents deformation of the upper end of the mounting base.

[0010] Preferably, the lower end of the limiting member is provided with an arc-shaped clearance groove. When the display screen does not need to be rotated backward for adjustment, the telescopic plate is stored in the base plate, and the rotating connecting rod is used as the rotation axis to fold the adjustment mechanism upward so that it is set parallel to the rear end of the box. At this time, the fixing rod is placed in the clearance groove, and the limiting rod is engaged in the limiting groove at the top of the limiting member.

[0011] The beneficial effects of this utility model are: The display screen is adjusted and fixed at multiple angles through the cooperation of tension springs, limiting rods, limiting grooves and foot-operated connecting parts to obtain different viewing angles, adapt to different venues and different viewing angle requirements. The balance adjustment component ensures the stability of the display screen during vertical use and angle adjustment, effectively preventing the display screen from tipping over.

Detailed Implementation

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] like Figures 1 to 5 As shown, this utility model provides a step-adjustable angle sports field fence screen, including a box body 1. A module 2 is provided at the front end of the box body 1. An adjustment mechanism 3 is fixedly connected to the rear end of the bottom of the box body 1. The adjustment mechanism 3 includes a balance adjustment component 30. A U-shaped mounting base 31 is fixed to the upper end of the balance adjustment component 30. A fixing rod 32 is horizontally fixed to the lower front end of the mounting base 31. A rotating connecting rod 33 is horizontally provided at the upper front end of the mounting base 31. An L-shaped sliding groove 310 is symmetrically opened at the upper rear end of the mounting base 31. A limiting rod 34 is horizontally provided in the L-shaped sliding groove 310. A tension spring 3 is connected between the fixing rod 32 and the limiting rod 34. 5. A foot-operated connector 36 is provided on the outer rear end of the mounting base 31. Rotary connecting holes a360 are symmetrically opened on both sides of the front end of the foot-operated connector 36. The limiting rod 34 passes through the rotating connecting hole a360. A U-shaped limiting member 38 is fitted on the upper end of the mounting base 31. A rotating connecting hole b380 is opened laterally at the lower rear end of the limiting member 38. The rotating connecting rod 33 passes through the rotating connecting hole b380. Multiple limiting grooves 381 are provided at the rear end of the limiting member 38. The limiting rod 34 can be snapped into the limiting groove 381. A fixing plate 39 is fixedly connected to the front end of the limiting member 38. The fixing plate 39 is fixedly connected to the middle of the lower end of the box body 1.

[0018] In use, stepping on the connecting piece 36 causes it to move backward, moving the limiting rod 34 backward within the L-shaped groove 310. The tension spring 35 is then stretched. At this point, the housing 1 is rotated backward around the axis of the rotating connecting rod 33. The limiting rod 34 is then engaged in the corresponding limiting groove 381 according to the required rotation angle. Specifically, when the limiting rod 34 aligns with the selected limiting groove 381, the stepping on the connecting piece 36 is released. The tension spring 35, under its own restoring force, pulls the limiting rod 34 forward into the limiting groove 381, thus fixing the housing in place. Figure 6 , Figure 7 As shown, the limiting groove 381 corresponds to multiple adjustment angles, including a limiting groove 381 at the top of the limiting member 38 corresponding to 0°, where 0° indicates that the adjusting mechanism 3 is parallel to the housing 1, and a limiting groove 381 at the middle of the rear end of the limiting member 38 corresponding to a 45° angle. The corresponding angles are 70°, 80°, and 90°. Of course, more limiting grooves 381 corresponding to different angles can be opened as needed.

[0019] Furthermore, the balance adjustment assembly 30 includes a hollow base plate 300, within which a telescopic plate 301 is inserted. A groove 3000 is formed at the upper end of the base plate 300, and a fixing bolt 302 is installed within the groove 3000. The lower end of the fixing bolt 302 can press downwards against the lower inner wall of the telescopic plate 301, causing the lower wall of the telescopic plate 301 to abut and lock against the lower inner wall of the base plate 300. By loosening the fixing bolt 302, the telescopic plate 301 can be extended forward; then, by tightening the fixing bolt 302, the problem of the display screen tipping over when its center of gravity shifts during angle adjustment is effectively prevented.

[0020] Furthermore, the rear side walls of the mounting base 31 are arc-shaped surfaces 311, and the front sides of the foot-operated connector 36 are provided with guide grooves 361. The two sides of the mounting base 31 are embedded in the guide grooves 361, and the inner wall of the guide grooves 361 abuts against the upper part of the arc-shaped surface 311. When the foot is pressed down on the foot-operated connector 36, the foot-operated connector 36 slides down along the arc-shaped surface 311. As the foot-operated connector 36 moves down, it moves backward, causing the limiting rod 34 to move backward, releasing the locking relationship between the limiting rod 34 and the limiting groove 381. The guide groove 361 ensures that the foot-operated connector 36 moves along the arc-shaped surface 311 within a preset stroke.

[0021] Furthermore, a reinforcing rib 312 is fixed inside the mounting base 31, which effectively increases the strength of the mounting base 31. An encapsulation plate 37 is fixedly connected to the upper opening of the mounting base 31, which effectively strengthens the upper end of the mounting base 31 and effectively prevents deformation of the upper end of the mounting base 31.

[0022] Furthermore, such as Figure 6 As shown, the lower end of the limiting member 38 is provided with an arc-shaped clearance groove 382. When the display screen does not need to be rotated backward for adjustment, the telescopic plate 301 is stored in the base plate 300, and the rotating connecting rod 33 is used as the rotation axis to fold the adjustment mechanism 3 upward, so that it is set parallel to the rear end of the housing 1. At this time, the fixing rod 32 is placed in the clearance groove 382, ​​and the limiting rod 34 is engaged in the limiting groove 381 at the top of the limiting member 38.
