For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0035] The utility model is further described below in conjunction with the accompanying drawings:

[0036] Example 1: Figure 1-Figure 6 As shown, a display screen with a self-locking installation structure includes a shell 1 and a rear cover 17, the rear cover 17 is fixedly arranged on the shell 1, a pressure rod 3 is embedded on the side wall of the rear cover 17, the pressure rod 3 is rotatably connected to the inner wall of the rear cover 17, a slider 9 and a limiting groove 15 are arranged in the shell 1, one end of the pressure rod 3 is connected to the slider 9, a first spring 10 is arranged on the side wall of the slider 9, the other end of the first spring 10 is connected to the shell 1, and a reset mechanism is arranged on the other opposite side wall of the slider 9; the limiting groove 15 is located on the inner wall of the shell 1, a second spring 16 and a limiting strip 14 are arranged in the limiting groove 15, the limiting strip 14 is located above the second spring 16, a push column 2 is also fixedly arranged on the limiting strip 14, and the free end of the push column 2 is located on the outside of the shell 1.

[0037] like Figure 3 and Figure 5As shown, the reset mechanism includes a first support rod 7, a second support rod 8, a push rod 6 and an elongated hole 4. The elongated hole 4 is arranged on the housing 1. The first support rod 7 and the second support rod 8 are hinged to each other to form a connecting rod mechanism. One end of the connecting rod mechanism is hinged to the slider 9, and the other end is hinged to the inside of the housing 1. The push rod 6 is connected to the connection between the first support rod 7 and the second support rod 8, and one end of the push rod extends out of the housing 1 from the elongated hole 4 and is fixedly provided with a pressing plate 5. Such an arrangement can change the length of the connecting rod mechanism composed of the first support rod 7 and the second support rod 8 by changing the shape of the mutually hinged first support rod 7 and the second support rod 8, so as to realize the pushing of the slider 9.

[0038] Specifically, there are at least two connecting rod mechanisms composed of the first support rod 7 and the second support rod 8, and the push rod 6 is connected to the two connecting rod mechanisms at the same time. Such an arrangement can maintain the position of the push rod 6.

[0039] like Figure 2 and Figure 4 As shown, a slide rod 12 is fixedly provided on the inner wall of the housing 1, and the free end of the slide rod 12 passes through the first spring 10 and then penetrates the slider 9, and the slider 9 slides relative to the slide rod 12. A push rod 13 is also hinged on the slider 9, and the free end of the push rod 13 is hinged to the pressure rod 3. Such a setting can guide the movement of the slider 9.

[0040] Specifically, the axial direction of the push column 2 is the same as the output direction of the second spring 16 . This arrangement can ensure that the limiting rod can be pushed to slide into the limiting groove 15 by pressing the push column 2 .

[0041] like Figure 6 As shown, a card slot 19 is provided on the limit strip 14, the position of the card slot 19 is opposite to the position of the slide bar 12, and the height of the limit strip 14 does not exceed the depth of the limit slot 15. In this way, the limit strip 14 can be limited by the mutual cooperation of the card slot 19 and the slide bar 12.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, a pad 18 is fixedly provided on the pressure rod 3, and the material of the pad 18 is rubber. Such a setting can cover the gap through the pad 18 when the pressure rod 3 is embedded in the side wall of the rear cover 17, making the overall display more beautiful. At the same time, the pad 18 made of rubber can also prevent sliding when being fixed.

[0043] Specifically, a rotating shaft 11 is fixedly provided on the pressure rod 3 , and both ends of the rotating shaft 11 are rotatably connected to the rear cover 17 , respectively. Such an arrangement ensures that the pressure rod 3 and the rear cover 17 can rotate relative to each other.

[0044] Working process of this embodiment: before use, the device is in the initial state. Figure 2As shown, the first spring 10 is compressed, and the second spring 16 is extended, pushing the limit strip 14 out of the limit groove 15 to block the slider 9. The pressure rod 3 is pulled by the push rod 13 and rotates and embeds into the side wall of the rear cover 17. The connecting rod mechanism composed of the first support rod 7 and the second support rod 8 is extended, and the push rod 6 is retracted into the shell 1 until the pressure plate 5 at the end of the push rod 6 is in contact with the outer wall of the shell 1.

[0045] When in use, align the rear cover 17 of the display with the mounting groove on the control cabinet, and then press the display into the mounting groove, the push column 2 will contact the control cabinet housing 1, and be pushed into the housing 1 by the control cabinet housing 1, when the push column 2 moves into the housing 1, it will push the limit bar 14 to move into the limit groove 15, when the limit bar 14 moves into the limit groove 15, the second spring 16 will be compressed, that is, from Figure 3 The status shown changes to Figure 4 In the state shown, when the limit bar 14 completely enters the limit groove 15, the slider 9 loses its obstruction. At this time, the first spring 10 will extend and push the slider 9 to move rightward along the slider 12. When the slider 9 moves along the slider 12, it will push the pressure rod 3 to rotate around the rotating shaft 11 through the push rod 13. When the pressure rod 3 is rotated, the pressure rod 3 embedded in the rear cover 17 will extend from the side wall of the rear cover 17 and cooperate with the control cabinet to fix the display screen. At the same time, the connecting rod mechanism composed of the first support rod 7 and the second support rod 8 will be pushed to shorten its length, and the push rod 6 will move outward from the long hole 4 to push the pressure plate 5 to separate from the shell 1.

[0046] At this time, the rubber pad 18 on the pressure rod 3 will fit with the control cabinet, which can not only fix the display screen, but also increase friction and reduce vibration.

[0047] When the display screen needs to be removed from the control cabinet, the push rod 6 is pushed into the housing 1 through the pressure plate 5, so that the push rod 6 moves and then pushes the connecting rod mechanism composed of the first support rod 7 and the second support rod 8. When the first support rod 7 and the second support rod 8 are pushed, the lengths begin to increase. At this time, the slider 9 is pushed by the first support rod 7 and moves to the left along the slider 12, that is, from Figure 4 The status shown changes to Figure 3In the state shown, when the slider 9 slides in the opposite direction along the slide rod 12, the first spring 10 will be compressed. When the slider 9 is completely moved over the limiting groove 15, the second spring 16 will begin to extend and push the limiting strip 14 out of the limiting groove 15. When the slot 19 on the limiting strip 14 contacts the slide rod 12, the limiting strip 14 will be limited. At this time, the pressure applied to the pressure plate 5 is cancelled, and the first support rod 7 will no longer provide thrust for the slider 9. The first spring 10 will push the slider 9 to move rightward along the slide rod 12 again. However, at this time, since the limiting strip 14 extends out of the limiting groove 15, it blocks the sliding of the slider 9 and the slider 9 is blocked on the left side of the limiting block. After the limiting strip 14 slides out of the limiting groove 15, the push column 2 will be pushed out of the housing 1 again and reset for the next use.

[0048] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
