DETAILED DESCRIPTION

[0023] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 and Figure 2As shown, a processing device for the back panel of an electronic product display screen includes a workbench 1, fixed frames 3 are fixedly installed at both ends of the workbench 1, guide shafts 4 are fixedly installed on the fixed frames 3, the same guide frame 5 is slidably connected between the guide shafts 4 on both sides, and a positioning member 6 is slidably provided on the guide frame 5. A support platform 2 is fixedly installed on the side of the workbench 1 facing the guide frame 5, and the support platform 2 is used to adapt to the screen back panel 7. The multiple holes on the screen back panel 7 can realize the suspended jacking of the screen back panel 7, so as to improve the supporting effect of the screen back panel 7 and facilitate the subsequent positioning effect.

[0025] As an implementation method in this embodiment, Figure 2-Figure 4 As shown, the positioning member 6 includes a slider 8 and an adjusting shaft 9 that are connected to each other. The slider 8 and the adjusting shaft 9 rotate and slide with each other, that is, the adjusting shaft 9 and the slider 8 can slide relatively, and at the same time, the slider 8 and the adjusting shaft 9 can rotate relatively. A pressing piece for pressing the screen back panel 7 is provided at one end of the adjusting shaft 9, and the screen back panel 7 is pressed by the pressing piece. A plurality of card slots 16 are provided on the outside of the adjusting shaft 9, and an abutment sheet 15 that is engaged with the card slot 16 is fixedly mounted on the slider 8. The abutment sheet 15 has elastic force. When in use, the slider 8 passes through the adjusting shaft 9 and moves downward, so that the adjusting shaft 9 drives the pressing piece to press the screen back panel 7, and is clamped between the abutment sheet 15 and the card slot 16 to prevent the adjusting shaft 9 from moving upward and falling off after the screen back panel 7 is pressed downward by the pressing piece.

[0026] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, the pressing piece includes an elastic sheet 12 and a pressing plate 14 which are fixedly connected to each other. The pressing plate 14 presses the screen back plate 7. The middle part of the elastic sheet 12 is fixed to the end of the adjusting shaft 9. When the adjusting shaft 9 presses the middle part of the elastic sheet 12, the elastic sheet 12 is deformed due to the pressure, and the pressing plate 14 is pressed against the screen back plate 7 by its own elastic force, so as to achieve a positioning effect on the screen back plate 7. A limiting plate 13 is provided on the pressing plate 14 to limit the two ends of the elastic sheet 12. The limiting plate 13 is used to prevent the ends of the elastic sheet 12 from being deformed after being pressed, so as to improve the elastic sheet 12. The stability of the end portion. During the deformation of the elastic sheet 12, space can be provided for the end portion of the abutment sheet 15 to be inserted into the card slot 16 to move, thereby avoiding misalignment between the abutment sheet 15 and the card slot 16, and affecting the abutment effect of the abutment sheet 15 on the card slot 16. The side wall of the adjusting shaft 9 is provided with an arc groove 17 along the axial direction of the adjusting shaft 9. The arc groove 17 is provided on multiple card slots 16 on the same side to ensure that when the adjusting shaft 9 is pressed against the screen back panel 7 through the pressing piece, the end portion of the abutment sheet 15 can move smoothly along the arc groove 17, thereby reducing the smoothness of the abutment sheet 15 during movement and reducing loss.

[0027] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, in order to improve the accuracy of pressing during the movement of the adjusting shaft 9, a pressing block 10 is slidably connected to the outside of the adjusting shaft 9, and a spring 11 is arranged between the pressing block 10 and the slider 8. In the initial state, the spring 11 lifts the pressing block 10, and an arc-shaped flange portion is arranged on the periphery of the pressing block 10 to facilitate the user to grab and avoid sliding down after grabbing the pressing block 10. The bottom end of the pressing block 10 is pressed tightly against the side wall of the guide frame 5, which can prevent the slider 8 from sliding back and forth relative to the guide frame 5. At this time, the pressure plate at the top of the adjusting shaft 9 can be pressed so that the card slot 16 gradually pushes the abutting piece 15 toward both sides until the pressure plate 14 presses the screen back panel 7, and the spring 11 is pressed against the screen back panel 7. After the force sheet 12 is compressed, it is deformed, and the abutment sheet 15 is inserted into the corresponding slot 16. At this time, the elastic sheet 12 drives the adjustment shaft 9 to move upward through its own elastic force, and the abutment sheet 15 clamps the slot 16 to prevent the adjustment shaft 9 from moving upward, thereby effectively improving the convenience of pressing. After the pressure plate 14 finishes pressing the screen back panel 7, the adjustment shaft 9 is rotated to gradually separate the slot 16 on the side wall of the adjustment shaft 9 from the end of the abutment sheet 15, and the abutment sheet 15 is abutted against the smooth cylindrical surface of the adjustment shaft 9, thereby releasing the restriction of the abutment sheet 15 on the slot 16. After the adjustment shaft 9 is pulled up, the slot 16 is rotated again until it is engaged with the abutment sheet 15, and subsequent operations can be performed.

[0028] The working principle of the utility model is as follows: when in use, first place the screen back panel 7 on the support table 2, and adjust the position of the positioning piece 6 so that the positioning piece 6 moves to the corresponding position of the screen back panel 7 to be positioned. Secondly, hold the pressing block 10 and press it down. The spring 11 bends after being compressed, so that the pressing block 10 is pressed against the side wall of the guide frame 5, so as to achieve the pre-positioning effect after the pressing block 10 and the guide frame 5 are pressed. The pressure plate at the top of the adjusting shaft 9 is pressed so that the slot 16 gradually pushes the abutment piece 15 toward both sides until the pressure plate 14 presses the screen back panel 7, and the elastic piece 12 is deformed after being compressed, and the abutment piece 15 is inserted into the corresponding slot 16. At this time, the elastic piece 12 drives the adjusting shaft 9 to move upward through its own elastic force, and the abutment piece 15 clamps the slot 16, thereby blocking the adjusting shaft 9 from moving upward, effectively improving the convenience of pressing.

[0029] When resetting is required, rotate the adjusting shaft 9 so that the slot 16 on the side wall of the adjusting shaft 9 is gradually separated from the end of the abutment sheet 15, and the abutment sheet 15 abuts against the smooth cylindrical surface of the adjusting shaft 9, thereby releasing the restriction of the abutment sheet 15 on the slot 16. After pulling up the adjusting shaft 9, rotate the slot 16 again until it is engaged with the abutment sheet 15, and then proceed with subsequent operations.

[0030] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
