This utility model transforms the L-shaped splicing structure of the traditional background board into a T-shaped splicing structure, which has a wider range of applications and is more practical.

[0004] However, this design transforms the L-shaped splicing structure of the traditional background board into a T-shaped splicing structure, which has a wider range of applications. However, there may still be incompatibility issues with background boards of certain specifications or materials. In actual applications, it needs to be adapted and adjusted according to the different sizes and weights of background boards, which may limit its use in certain specific scenarios. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a T-shaped clip with an adjustment function to solve the problem of upgrading the traditional L-shaped splicing structure to a T-shaped splicing structure in the comparative document. Although the scope of application has been expanded, it still faces the problem of incompatibility with background boards of specific specifications or materials. In actual application, it is necessary to adapt to the size and weight of the background board, which may limit its application flexibility in certain specific scenarios.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a T-shaped buckle with an adjustment function, comprising a first joint, a second joint and a third joint fixedly connected on the left and right sides of the first joint respectively, a first fixing piece provided at the right angle where the first joint and the second joint are connected, a second fixing piece fixedly connected inside the first joint, a first elastic sheet and a second elastic sheet fixedly installed inside the first joint, the first elastic sheet and the second elastic sheet are located on both sides of the second fixing piece, the second joint and the third joint are on the same horizontal line, the first joint, the second joint and the third joint are T-shaped structures, a third elastic sheet and a fourth elastic sheet are fixedly installed in the second joint and the third joint, a second background plate is buckled in the first joint, and the first background plate is buckled in the second joint and the third joint.

[0007] By adopting the above technical solution, when in use, the first joint, the second joint and the third joint cooperate with each other to facilitate fixing the first background plate and the second background plate in the T-shaped buckle, and the T-shaped structure itself has high stability and can withstand forces and torques from different directions. This design enables the joint to maintain its stability and reliability in a complex working environment. The first fixing piece is provided at the right angle where the first joint and the second joint are connected, which helps to enhance the strength and stability of the connection and prevent breakage or damage caused by stress concentration. The second fixing piece fixedly connected in the first joint further enhances the overall structural strength of the joint, so that it can withstand a larger load. The first elastic sheet and the second elastic sheet are connected. The elastic pieces are located on both sides of the second fixing piece, and they can provide a certain elastic support. The third elastic piece and the fourth elastic piece fixedly installed in the second joint and the third joint also play the role of elastic support, ensuring that the joints can have a stable clamping effect on the first background board and the second background board under different working conditions. This structure is conducive to more convenient installation and disassembly of the first background board and the second background board, and through the characteristics of the first elastic piece, the second elastic piece, the third elastic piece and the third and fourth elastic pieces themselves, the first background board and the second background board of different sizes can be clamped and fixed. This structure is conducive to setting up a single background board, which can improve the practicality and flexibility of the entire T-shaped buckle with adjustment function.

[0008] The present invention is further configured such that reinforcing ribs are fixedly installed on both sides of the bottom of the first joint in a symmetrical structure, and the second joint and the third joint are both fixedly connected to the reinforcing ribs.

[0009] By adopting the above technical solution, the addition of reinforcing ribs effectively disperses the stress of the joint when it is subjected to external forces, making the stress distribution more uniform, thereby reducing the risk of joint damage caused by stress concentration. The symmetrical installation and fixed connection of the reinforcing ribs enable the joint to maintain its original shape and size when subjected to various external forces, effectively preventing deformation and twisting of the joint. The rigid effect of the reinforcing ribs makes the joint have higher resistance when subjected to bending or torsional forces, thereby improving the overall stability of the joint.

[0010] The present invention is further configured such that a first notch is provided at the end of the first joint, and a second notch is provided at the end of the second joint and the end of the third joint.

[0011] By adopting the above technical solution, the first notch and the second notch can be used as positioning marks for assembly between the T-shaped clips, making it easier to use the T-shaped clips on the outside of the first background plate and the second background plate during the connection process.

[0012] The present invention is further configured such that the first joint is provided with a plurality of first slots, and the second joint and the third joint are provided with a plurality of second slots.

[0013] By adopting the above technical solution, the first slot and the second slot can reduce the overall weight of the T-shaped buckle while ensuring strength and stability. In some cases, the first slot and the second slot can also improve the heat dissipation performance of the T-shaped buckle. By increasing the surface area and ventilation, it can help dissipate the heat generated inside the T-shaped buckle.

[0014] The present invention is further configured such that a third fixing member is fixedly connected to each of the second joint and the third joint, and the third fixing member is located between the third elastic piece and the fourth elastic piece.

[0015] By adopting the above technical solution, when the third fixing member is located between the third elastic sheet and the fourth elastic sheet, a more solid support structure can be formed to prevent the joint from loosening due to deformation of the third elastic sheet and the fourth elastic sheet, and the fixing member located between the third elastic sheet and the fourth elastic sheet can limit excessive deformation of the elastic sheet.

[0016] In summary, the present invention has the following beneficial effects:

[0017] 1. This utility model achieves efficient and stable fixation of the first and second background panels through the T-shaped buckle and its embedded multiple joints and elastic sheet system. The T-shaped structure enhances load-bearing and torsion resistance, the fixings between the joints enhance the connection strength, and the elastic sheet provides flexible clamping force to support background panels of different sizes. The overall design is easy to install and disassemble, and improves the practicality and flexibility of the T-shaped buckle, making it particularly suitable for scenes where background panels need to be erected.

[0018] 2. The utility model significantly optimizes the stress distribution of the joint by adding reinforcing ribs, reduces the risk of stress concentration, and enhances the joint's ability to resist deformation and twisting due to external forces through its symmetrical installation and fixed connection. At the same time, it improves the stability of the joint under bending or torsional forces, thereby improving the overall durability and reliability of the joint. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] When in use, the mutual cooperation between the first joint 1 and the second joint 9 and the third joint 11 is conducive to fixing the first background plate 8 and the second background plate 17 in the T-shaped buckle, and the T-shaped structure itself has high stability and can withstand forces and torques from different directions. This design enables the joint to maintain its stability and reliability in a complex working environment. The first fixing member 4 is provided at the right angle where the first joint 1 and the second joint 9 are connected, which helps to enhance the strength and stability of the connection and prevent breakage or damage caused by stress concentration. The second fixing member 5 fixedly connected in the first joint 1 further enhances the overall structural strength of the joint, so that it can withstand a larger load. The first elastic sheet 2 and the second elastic sheet 6 are located at the second fixing member 5 on both sides, they can provide a certain degree of elastic support. The third elastic piece 7 and the fourth elastic piece 10 fixedly installed in the second joint 9 and the third joint 11 also play the role of elastic support, ensuring that the joints can stably clamp the first background plate 8 and the second background plate 17 under different working conditions. This structure facilitates more convenient installation and removal of the first background plate 8 and the second background plate 17.

The first slot 15 and the second slot 14 provided can reduce the overall weight of the T-shaped clip while ensuring strength and stability. In some cases, the first slot 15 and the second slot 14 can also improve the heat dissipation performance of the T-shaped clip. By increasing the surface area and ventilation, it can help dissipate the heat generated inside the T-shaped clip. When the third fixing member 16 is located between the third elastic sheet 7 and the fourth elastic sheet 10, a more solid support structure can be formed to prevent the joint from loosening due to deformation of the third elastic sheet 7 and the fourth elastic sheet 10, and the fixing member located between the third elastic sheet 7 and the fourth elastic sheet 10 can limit excessive deformation of the elastic sheet.
