Description

Technical Field

[0001] This utility model relates to the field of curved LED screen technology, specifically to a fixed connection structure for a curved LED screen housing. Background Technology

[0002] LED displays are widely used display cabinets composed of LED device arrays, used to display various information such as text, graphics, images, animations, market data, as well as television and video signals. LED displays have advantages such as color accuracy, wide dynamic range, high brightness, long lifespan, and reliable operation, and are increasingly popular. LED displays are widely used in commercial media, cultural performance markets, sports venues, information dissemination, news releases, securities trading, and other environments.

[0003] To achieve a better viewing experience, many existing LED screens are often made in an arc shape. The LED screen is spliced ​​together by multiple cabinets forming a certain angle (less than 180°).

[0004] However, currently, bolts and connecting locks are commonly used to connect adjacent LED cabinets, which is inconvenient to adjust and makes it difficult to precisely adjust the angle between the LED cabinets according to actual usage needs, which is not conducive to the presentation of display effects. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model proposes an arc-shaped LED screen cabinet fixing connection structure to solve the above problems.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] This utility model provides a fixed connection structure for an arc-shaped LED screen enclosure, comprising multiple enclosures arranged side by side, with a hinge installed between the side walls of two adjacent enclosures near their front ends, and further comprising:

[0008] An adjustment mechanism is installed between each of two adjacent boxes. The adjustment mechanism includes an arc rack and an adjustment shaft. The adjustment shaft is rotatably mounted on one side of the inner cavity of the box and is equipped with a gear. The box has a through-hole on the side adjacent to the adjustment shaft. The arc rack is installed on the outer wall of the other side of the box. The arc center of the arc rack is collinear with the hinge shaft on the box on the side where it is located. The arc rack can slide through the through-hole of the adjacent box and mesh with the gear inside the adjacent box.

[0009] A control mechanism is provided for each of the aforementioned adjusting shafts, and is used to control the rotation or locking of the adjusting shafts.

[0010] Furthermore, the control mechanism includes a circular groove, a spring, and a column cap. The top end of the adjusting shaft passes through the top of the housing. The circular groove is opened on the top of the housing with the adjusting shaft as the center, and multiple toothed grooves are evenly distributed on the edge of the circular groove. The column cap is slidably sleeved on the top end of the adjusting shaft, and multiple limiting teeth that match the toothed grooves are evenly distributed on its edge. The inside of the column cap is connected to the adjusting shaft through a spring to provide elastic force to pull the column cap into the circular groove.

[0011] Furthermore, a limit block is provided on one side of the top of the adjusting shaft, and a slot adapted to the limit block is provided on the inner side of the column cap.

[0012] Furthermore, the top edges of the circular groove and each toothed groove are provided with rounded chamfers.

[0013] Furthermore, each of the two adjacent boxes has a communication opening on the side closest to each other.

[0014] Furthermore, a sealing cover is connected between the edges of two adjacent boxes.

[0015] As can be seen from the above technical solution, this utility model provides a fixed connection structure for an arc-shaped LED screen housing:

[0016] By controlling the rotation of the adjusting shaft, the gear drives the circular arc rack to mesh and transmit power. In turn, the circular arc rack drives the corresponding hinge to open and close at the corresponding angle, thereby achieving angle adjustment between adjacent cabinets. This allows two adjacent cabinets to stay at any angle, making it convenient to adjust according to actual usage needs and improving the display effect of the LED screen. Attached Figure Description

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] like Figure 1-4 As shown, the present embodiment provides a fixed connection structure for an arc-shaped LED screen cabinet, which includes multiple cabinets 1 arranged side by side. A hinge 11 is installed between the side walls of two adjacent cabinets 1 near the front end, so that the two adjacent cabinets 1 can rotate based on the hinge 11, thereby adjusting the angle between the cabinets 1. The present invention also includes an adjustment mechanism 2 and a control mechanism 3.

[0028] Preferably, each of the two adjacent boxes 1 has a communication port 13 on the side closest to each other to facilitate the wiring connection between the boxes 1.

[0029] One adjustment mechanism 2 is installed between each of two adjacent boxes 1. The adjustment mechanism 2 includes an arc rack 21 and an adjustment shaft 22. The adjustment shaft 22 is rotatably installed on one side of the inner cavity of the box 1. A gear 23 is provided on the adjustment shaft 22. A through-hole 12 is opened on the side of the box 1 adjacent to the adjustment shaft 22. The arc rack 21 is installed on the outer wall of the other side of the box 1. The arc center of the arc rack 21 is collinear with the hinge 11 axis on the side box 1 where it is located. The arc rack 21 can slide through the through-hole 12 of the adjacent box 1 and mesh with the gear 23 inside the adjacent box 1.

[0030] By controlling the rotation of the adjusting shaft 22, the gear 23 drives the arc rack 21 to mesh and transmit power. In turn, the arc rack 21 drives the corresponding hinge 11 to open and close at the corresponding angle, thereby realizing the angle adjustment between adjacent boxes 1. This allows two adjacent boxes 1 to stay at any angle, which is convenient for adjustment according to actual use needs and improves the display effect of the LED screen.

[0031] One control mechanism 3 is provided for each of the adjustment shafts 22, which is used to control the rotation or lock of the adjustment shaft 22.

[0032] Specifically, the control mechanism 3 includes a circular groove 31, a spring 32, and a cap 33. The top end of the adjusting shaft 22 passes through the top of the housing 1. The circular groove 31 is opened at the top of the housing 1 with the adjusting shaft 22 as the center, and multiple toothed grooves 311 are evenly distributed on the edge of the circular groove 31. The size of the cap 33 is adapted to the size of the circular groove 31. The cap 33 is slidably sleeved on the top end of the adjusting shaft 22, and multiple limiting teeth 331 that are adapted to the toothed grooves 311 are evenly distributed on its edge. When the cap 33 slides down into the circular groove 31, the limiting teeth 331 will also be engaged in the toothed grooves 311. The interior of the cap 33 is connected to the adjusting shaft 22 through the spring 32 to provide elastic force to pull the cap 33 into the circular groove 31.

[0033] In practical use, pulling up the cap 33 disengages it from the groove 31, allowing the adjusting shaft 22 to rotate by rotating the cap 33. When two adjacent housings 1 are adjusted to the appropriate angle, releasing the cap 33 allows it to be pulled into the groove 31 by the spring 32, enabling each limiting tooth 331 to engage with its corresponding groove 311, thus locking the adjusting shaft 22. This allows for quick adjustment of the angle between the housings 1, improving adjustment efficiency. Furthermore, the more limiting teeth 331 and grooves 311 there are, the higher the adjustment accuracy.

[0034] Preferably, a limit block 221 is provided on one side of the top end of the adjusting shaft 22, and a slot (not shown) adapted to the limit block 221 is provided on the inner side of the column cap 33, so that the column cap 33 can only move up and down at the top end of the adjusting shaft 22, ensuring that the column cap 33 can drive the adjusting shaft 22 to rotate.

[0035] Furthermore, a handle (not shown) can be installed on the column cap 33 for manual control and adjustment.

[0036] Preferably, the top edges of the circular groove 31 and each toothed groove 311 are provided with rounded chamfers 312, which helps to guide the column cap 33 into the circular groove 31 and prevents it from getting stuck.

[0037] Preferably, a sealing cover 14 is connected between the edges of two adjacent boxes 1. The sealing cover 14 can be a corrugated cover, which helps to prevent dust from falling into the gap between the boxes 1 or into the inside of the boxes 1.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
