Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, in particular to a telescopic bracket. Background Art

[0002] As an efficient information dissemination tool, LED display screens are mainly used to display various information such as text, images, videos, and video signals. They are widely used in airports, shopping malls, hotels, high-speed railways, subways, cinemas, exhibitions, office buildings and other places, becoming an indispensable part of modern life.

[0003] Due to different application scenarios, some displays require hanging installation, while others require stacking installation. Regardless of the installation method, a bracket must be installed on the back of the LED display to improve the structural stability of the LED display. In addition, during installation, the curvature of the LED display must be flexibly adjusted according to the specific application scenario to meet the visual requirements of different angles.

[0004] However, in practice, constructing and splicing LED displays presents several challenges. Because existing brackets are fixed in length, each specific project often requires preparing a variety of brackets of varying lengths to achieve the desired curvature. This practice not only increases transportation costs and storage space requirements, but also leads to confusion on-site and increases the cost of bracket management and identification.

[0024] Example

[0025] See also Figure 2 , Figure 2This is a cross-sectional view of the utility model. This embodiment provides a telescopic bracket, comprising a thick tube 1, a thin tube 2, a connecting rod 3, a first locking member 4, a second locking member 5, and a clamp assembly 6. The thin tube 2 is sleeved in the thick tube 1, and the connecting rod 3 is sleeved in the thin tube 2. The length of the thin tube 2 is greater than or equal to the length of the thick tube 1, and the length of the thick tube 1 is greater than or equal to the length of the connecting rod 3. The length of the connecting rod 3 is 1 / 2 to 4 / 5 of the length of the thick tube 1. The connecting rod 3 is a guide screw. If the connecting rod 3 is too short, the telescopic length is limited. If the length of the connecting rod 3 is too long, it means that the overlapping part of the thick tube 1 and the thin tube 2 is too small. Once the clamp assembly 6 is not locked, the thin tube 2 is likely to fall out suddenly, which is likely to injure workers when assembling the display screen box.

[0026] See also Figure 1 Combined together Figure 2 , Figure 1 It is a schematic diagram of the overall structure of the present utility model. The second locking piece 5 is provided at the end of the thin tube 2 away from the thick tube 1, and the first locking piece 4 is provided at the end of the thick tube 1 away from the thin tube 2. The first locking piece 4 and the second locking piece 5 are both duckbill buckles. A metal ring 21 is provided at the end of the thin tube 2 close to the thick tube 1. The metal ring 21 is integrally formed with the thin tube 2. The metal ring 21 can also be welded to the thin tube 2. A silicone protective sleeve is provided on the metal ring 21. The silicone protective sleeve can prevent the metal ring 21 from scratching the protective paint on the surface of the connecting rod 3 during the extension and retraction of the thin tube 2. One end of the connecting rod 3 is connected to the first locking piece 4, and the end of the connecting rod 3 away from the first locking piece 4 is sleeved in the metal ring 21. More specifically, both ends of the connecting rod 3 are provided with a threaded structure. After one end of the connecting rod 3 passes through the metal ring 21, it is fixed by a limit nut 7. After the end of the connecting rod 3 away from the metal ring 21 is screwed to the first locking piece 4, it is also fixed by a limit nut 7. This threaded connection design facilitates the installation and replacement of the connecting rod. The thin tube 2 carries the metal ring 21 and moves left and right along the connecting rod 3 in the body of the thick tube 1, thereby achieving expansion and contraction.

[0027] See also Figure 3 , Figure 3 This is an exploded view of the clamp assembly of the present invention. The clamp assembly 6 is arranged at one end of the thick tube 1 near the thin tube 2. The clamp assembly 6 includes a ring-shaped clamp 61, an open-shaped locking piece 62 and a fastener 63. The ring-shaped clamp 61 and the open-shaped locking piece 62 are integrally formed. The ring-shaped clamp 61 and the open-shaped locking piece 62 are made of aluminum, copper, iron or stainless steel with good flexibility. This type of material is used to ensure that the clamp assembly 6 can be easily deformed to fit the thin tube 2, and can also maintain its shape and provide sufficient clamping force. An arc-shaped gap is provided between the ring-shaped clamp 61 and the open-shaped locking piece 62, and the length of the arc-shaped gap accounts for 2 / 3 of the total circumference length of the ring-shaped clamp 61. This length can facilitate the deformation of the open-shaped locking piece 62 to achieve a tightening effect.

[0028] The ring-shaped clamp 61 is fixedly connected to the thick tube 1. In this application, the ring-shaped clamp 61 is welded to the thick tube 1. The open-shaped locking member 62 is sleeved on the thin tube 2. A rubber gasket 64 or silicone gasket is provided between the open-shaped locking member 62 and the thin tube 2. The rubber gasket 64 can prevent the clamp from scratching the protective paint on the surface of the thin tube 2 during the expansion and contraction process of the thin tube 2. The open end of the open-shaped locking member 62 is respectively provided with a first protrusion 621 and a second protrusion 622. The first protrusion 621 and the second protrusion 622 are each provided with a through hole 623. The fastener 63 is passed through the through hole 623 and tightened to lock the thin tube 2.

[0029] When in use, first fix one end of the thick tube to one side of the LED display screen through the first locking piece 4, then loosen the fastener 63 of the clamp assembly 6, pull the thin tube 2 out of the thick tube 1 until the second locking piece 5 is fixed to the other side of the LED display screen, and then tighten the fastener 63 of the clamp assembly 6 to complete the installation of the telescopic bracket.

[0030] The telescopic bracket provided in this embodiment can not only perfectly replace brackets of different lengths to meet the bending requirements of different LED display screens, making the installation of LED display screens more flexible and shortening the installation time, but also simplifying logistics and reducing the costs of various links such as production, transportation and storage. In addition, the biggest feature of this application is its high safety. On the one hand, a clamp assembly 6 is provided at the connection between the thick tube 1 and the thin tube 2 to ensure that the two are tightly connected to prevent the thin tube 2 from falling off. On the other hand, a connecting rod 3 is added to the thin tube 2, and the lengths of the thick tube 1, the thin tube 2 and the connecting rod 3 are limited. In this way, even in extreme cases, if the clamp assembly 6 is not locked, it can ensure that the thin tube 2 will not accidentally slide out of the thick tube 1, providing double safety protection for on-site workers.

[0031] The above is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
