[0037] An elastic snap-fit ​​structure is provided between the first frame body 1 and the second frame body 10, and the elastic snap-fit ​​structure includes a male buckle module 3 and a female buckle module 2, wherein the male buckle module 3 is installed on the first frame body 1, and the female buckle module 2 is installed on the second frame body 10, and the male buckle module 3 includes a swingable connecting hook 4, and the connecting hook 4 has an elastic contraction structure, and the elastic contraction structure elastically drives the length of the connecting hook 4 to elastically shrink; the female buckle module 2 includes a female seat plate 21 installed on the second frame body 10, and the female seat plate 21 is formed with a barb plate 22 for the connecting hook 4 to hook;

[0038] When it is necessary to splice multiple frame bodies into a large screen, an elastic snap-on structure can be used to achieve detachable connection. When connecting, the male buckle module 3 installed on the first frame body 1 is hooked with the hook plate 22 installed on the first frame body 1 through the connecting hook 4. After connection, the elastic contraction structure elastically drives the length of the connecting hook 4 to elastically shrink, which can prevent the male buckle module 3 and the female buckle module 2 from separating, and the connection stability is better; when disassembling, it is only necessary to swing the connecting hook 4 to disengage it from the hook plate 22 to complete the disassembly, which is convenient for disassembly and assembly, and easy to splice.

[0039] Specifically, the first frame body 1 is formed with a first connecting seat 23, the first connecting seat 23 is formed with multiple first connecting holes 24, the male buckle module 3 also includes a male buckle seat 31, and the male buckle seat 31 is installed in the first connecting hole 24; the second frame body 10 is formed with a second connecting seat 25, the second connecting seat 25 is formed with multiple second connecting holes 26, and the female seat plate 21 is installed in the second connecting hole 26.

[0040] In this embodiment, the male buckle module 3 is installed in the first connecting seat 23 of the first frame body 1 through the male buckle seat 31; the female buckle module 2 is installed in the second connecting seat 25 of the second frame through the female seat plate 21, so that both the male buckle module 3 and the female buckle module 2 can be stably installed.

[0041] Preferably, the male buckle module 3 also includes a swinging plate 32 that can be swingably mounted on the male buckle seat 31, and one end of the connecting hook 4 is rotatably mounted on the swinging plate 32. When the swinging plate 32 swings around the male buckle seat 31, the connecting hook 4 can move away from or approach the female buckle module 2. When the swinging plate 32 swings, it can drive the connecting hook 4 to approach the female buckle module 2 and hook with the barb plate 22 of the female buckle module 2 to achieve locking, thereby realizing the connection between the first frame body 1 and the second frame body 10.

[0042] Specifically, swing side plates 33 are vertically formed on both sides of the swing plate 32, and the two swing side plates 33 are respectively formed with coaxially aligned swing holes 34. A hinge shaft 35 that cooperates with the swing hole 34 is formed at one end of the male buckle seat 31. The swing plate 32 can swing around the hinge shaft 35 through the swing hole 34; the swing plate 32 rotates and cooperates with the hinge shaft 35 of the male buckle seat 31 through the swing hole 34 of the swing side plate 33, thereby realizing the swing of the swing plate 32, thereby driving the connecting hook 4 to move.

[0043] A first connecting shaft 36 is installed between the two swing side plates 33, and both ends of the first connecting shaft 36 extend outward respectively. One end of the connecting hook 4 is movably connected to the first connecting shaft 36, and the connecting hook 4 can swing around the first connecting shaft 36; when the swing plate 32 swings, the connecting hook 4 can swing around the first connecting shaft 36 to approach or move away from the female buckle module 2.

[0044] Specifically, the connecting hook 4 includes a driving bar 41, and the driving bar 41 includes a first connecting bar 42 and a second connecting bar 43 that are slidably fitted with each other. A first limit block 44 is formed at the outer end of the first connecting bar 42, and a second limit block 45 is formed at the inner end of the second connecting bar 43. A tension spring 46 that is simultaneously nested in the first connecting bar 42 and the second connecting bar 43 is installed between the first limit block 44 and the second limit block 45; after one end of the driving bar 41 is hooked with the hook plate 22, the swing plate 32 is swung so that the first connecting shaft 36 is away from the female buckle module 2, and the first connecting bar 42 and the second connecting bar 43 are fitted and slid. Under the drive of the tension spring 46, one end of the driving bar 41 remains hooked with the hook plate 22, and will not fall off, and the connection stability of the first frame body 1 and the second frame body 10 is further improved; and the first limit block 44 and the second limit block 45 can prevent the tension spring 46 from falling off, thereby ensuring the structural stability of the driving bar 41.

[0045] Specifically, there are two groups of driving strips 41. The inner end of the first connecting strip 42 is rotatably connected to the first connecting shaft 36. A hook shaft 47 is installed between the two second connecting strips 43. The hook shaft 47 can cooperate with the hook plate 22 for locking. The hook shaft 47 is parallel to the first connecting shaft 36. The driving strip 41 is hooked with the hook plate 22 through the hook shaft 47 to achieve a locking connection between the male buckle module 3 and the female buckle module 2. Under the action of elasticity, the male buckle module 3 maintains a pulling force away from the female buckle module 2, which can prevent the male buckle module 3 from separating from the female buckle module 2 and ensure the connection stability.

[0046] Furthermore, a power box 12 and a support assembly 13 for fixing the power box 12 are provided on the back of the first frame body 1 and the second frame body 10, the support assembly 13 includes a positioning surface 14 and a positioning groove 15 formed on the positioning surface 14, a connecting surface 16 formed on the bottom of the power box 12 that fits with the positioning surface 14, a raised positioning block 17 formed on the connecting surface 16, and the positioning block 17 is coaxially matched with the positioning groove 15; the screen is respectively installed on the fixing surface 11 on the front side of the first frame body 1 and the second frame body 10, the power box 12 fits with the positioning surface 14 of the support assembly 13 on the back side of the frame body through the connecting surface 16, and the positioning block 17 will be embedded in the positioning groove 15 of the connecting surface 16, so as to realize the connection in one direction, prevent lateral displacement, and improve the connection stability; the connection stability between the power box 12 and the positioning surface 14 is further improved by disassembling the connecting piece, and in addition, the connecting piece can be swung and disassembled according to needs, and the power box 12 can be disassembled for repair or replacement, thereby improving the disassembly efficiency.
