Description

Technical Field

[0001] The utility model relates to the technical field of display back panels, in particular to a back panel folding edge middle frame damage prevention structure. Background Art

[0002] The back panel of the monitor is buckled onto the middle frame, and the back panel is in direct contact with the middle frame. Since the middle frame is made of ABS-HB material and the back panel is made of SGCC T0.5mm metal material, after the back panel is installed, the monitor will move, vibrate due to aging, and transport, which will cause friction due to the gap between the middle frame and the back panel, resulting in middle frame chips and obvious fine scratches at the four corners of the middle frame and the back panel. Summary of the invention

[0003] The technical problem to be solved by the utility model is that after the back plate is installed on the middle frame, the middle frame will be worn due to transportation, vibration and movement of the display, thereby affecting product quality.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a back panel folded edge middle frame anti-damage structure, including a rectangular middle frame and a back panel buckled on the inner side of the middle frame, the inner side wall and the inner top wall of the middle frame are provided with snap-in grooves, and the folded edge of the back panel is provided with an adapting protrusion that is adapted to the snap-in groove. A gasket is adhered to the folded edge of the back panel, the thickness of the middle part of the gasket is greater than the thickness on both sides, and an elastic pushing structure is provided on the bottom plate at the bottom of the middle frame.

[0005] Preferably, the gasket is adhered to the adapting protrusion, and the gasket is attached to the movable end wall of the adapting protrusion.

[0006] Preferably, the gasket is made of Mylar sheet.

[0007] Preferably, the elastic pushing structure includes a top plate vertically slidably mounted on the bottom plate, the bottom of the top plate is connected to a spring, and the bottom end of the spring is fixedly connected to the bottom plate.

[0008] Preferably, an arc-shaped protrusion is provided on the top of the top plate.

[0009] The utility model provides a back panel folded edge middle frame anti-damage structure, adopts a gasket attached to the folded edge of the back panel, and fills the movable gap between the back panel and the middle frame with the gasket. After the back panel is installed, it can prevent the back panel and the middle frame from sliding relative to each other when the display is transported, moved or vibrated, thereby improving the quality of the product.

[0016] like Figure 1-4 As shown, the utility model proposes a back panel folded edge middle frame anti-damage structure, comprising a rectangular middle frame 1 and a back panel 2 buckled on the inner side of the middle frame 1, the inner side wall and the inner top wall of the middle frame 1 are provided with a snap-in groove 12, and an adapting protrusion 22 adapted to the snap-in groove 12 is provided on the folded edge 21 of the edge of the back panel 2, a gasket 23 is adhered to the folded edge 21 of the back panel 2, the thickness of the middle part of the gasket 23 is greater than the thickness on both sides, and an elastic pushing structure is provided on the bottom plate 11 at the bottom of the middle frame 1.

[0017] The folded edge 21 of the back plate 2 is a cutting surface, which is relatively sharp and has metal burrs. The sharp cutting surface contacts the contact surface of the middle frame 1. After relative sliding occurs, it will inevitably cause foreign matter such as middle frame chips and scratch the middle frame 1. After the gasket 23 is attached to the folded edge 21, the folded edge 21 can be effectively blocked to prevent the cutting surface from scratching the middle frame 1 when relative sliding occurs. In addition, the gasket 23 can be used as a filling material for the gap to prevent relative sliding between the middle frame 1 and the back plate 2.

[0018] The thickness of the gasket 23 at both sides is thinner than that in the middle, so that the staff can smoothly install the back plate 2 into the middle frame 1 when assembling the middle frame 1 and the back plate 2 .

[0019] like Figure 3 The gasket 23 is adhered to the adapting protrusion 22, and the gasket is attached to the movable end wall of the adapting protrusion 22. The gasket 23 is attached to the adapting protrusion 22 to prevent the edge of the adapting protrusion 22 from scratching the inner wall of the clamping groove 12.

[0020] As a preferred embodiment of the utility model. The gasket 23 is made of Mylar sheet. The material of the Mylar sheet is PET material, which has good flexibility and does not have problems such as falling off and burrs. After the Mylar sheet is attached as the gasket 23, the middle frame 1 directly contacts the Mylar sheet, which plays a buffering role in the engagement between the middle frame 1 and the back plate 2, thereby reducing the generation of middle frame scraps. The thickness of the Mylar sheet used is T0.05mm, and it is attached to the folded edge 21.

[0021] like Figure 1 and Figure 4 The elastic push structure includes a top plate 13 vertically slidably mounted on the bottom plate 11, the bottom of the top plate 13 is connected to a spring 15, and the bottom end of the spring 15 is fixedly connected to the bottom plate 11. After the back plate 2 is engaged in the middle frame 1, the top plate 13 is pushed by the spring 15, and the top plate 13 slides along the mounting groove 14 at the top of the bottom plate 11, and the top plate 13 pushes the back plate 2 to a state of being tightly fitted with the top of the middle frame 1.

[0022] like Figure 4 As shown, in order to ensure that the top plate 13 presses the back plate 2 tightly and facilitates the subsequent removal of the back plate 2 from the middle frame, an arc-shaped protrusion is provided on the top of the top plate 13. The middle part of the top plate 13 is used to press the back plate 2 tightly, and the edge of the top plate 13 is used to facilitate the subsequent insertion of a blade to press the top plate 13 down, and then the back plate 2 is removed from the middle frame 1.
