Description

Technical Field

However, this method can only detect whether there is an air leak, and it is not convenient to detect the location of the leak, resulting in a relatively limited function. Therefore, an outdoor display safety testing device is needed to meet people's needs. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-5 An outdoor display screen safety testing device includes a workbench 1 and a display screen module 2. A water tank 3 is provided on the workbench 1. A frame 4 is provided on the workbench 1. A lifting block 5 is provided inside the frame 4. A stepper motor 6 is provided on one side of the lifting block 5. A clamping mechanism 7 is provided on the output end of the stepper motor 6. The display screen module 2 is arranged on the clamping mechanism 7. An air pump 8 is provided on the workbench 1. The air pump 8 and the display screen module 2 are connected through an air pipe.

[0022] Add water to the water tank 3, connect the air pipe of the air pump 8 to the pre-drilled detection hole on the back of the display module 2, and install and fix the back of the display module 2 to the clamping mechanism 7. At this time, one side of the outer shell of the display module 2 is immersed in the water, and the air pump 8 is driven to work, so that the display module 2 is in an inflated state. After the pressure gauge of the air pump 8 stabilizes, stop the inflation and observe whether air bubbles are generated at the connection of the display module 2 immersed in the water. If no air bubbles are generated, the stepper motor 6 can be started, so that the clamping mechanism 7 drives the display module 2 to rotate 90°, so that the other vertical side is immersed in the water. Observe whether air bubbles are generated. Repeat this process until each side connection of the display module 2 is tested. If air bubbles are generated, the location of the air bubbles can be observed to make a direct observation of the leak point, so as to improve the detection effect.

[0023] Specifically, in this embodiment, an electric telescopic rod 9 is provided on the top of the frame 4. The telescopic end of the electric telescopic rod 9 is connected to the lifting block 5. The electric telescopic rod 9 enables the vertical lifting effect of the lifting block 5, thereby allowing the clamping mechanism 7 to drive the display module 2 to adjust its height, so that each side of the display module 2 can be immersed into the water source after it rotates.

[0024] Specifically, in this embodiment, the clamping mechanism 7 includes a clamping base 10, a screw 11 rotatably connected to the clamping base 10, an adjusting block 12 threadedly connected to the screw 11, two clamping blocks 13 slidably connected to the clamping base 10, and a connecting rod 14 rotatably connected between the two clamping blocks 13 and the adjusting block 12. A clamping plate 15 is provided on the same side of the two clamping blocks 13. The display module 2 is arranged between the two clamping plates 15. By rotating the screw 11, the height of the adjusting block 12 can be adjusted. Through the rotational connection of the connecting rod 14, the two clamping blocks 13 can move relative to each other, thereby facilitating the installation, fixing and removal of the display module 2 by the two clamping blocks 13 driving the clamping plate 15 respectively.

[0025] Specifically, in this embodiment, a bearing sleeve 16 is provided on the clamp 10, and the bottom end of the screw 11 is rotatably adapted to the bearing sleeve 16. The cross-section of the screw 11 located in the bearing sleeve 16 is T-shaped, which provides axial positioning effect for the screw 11 and improves the connection effect between the screw 11 and the clamp 10.

[0026] Specifically, in this embodiment, the clamp 10 has two adjustment grooves 17, which are arranged symmetrically to each other. The cross-section of the adjustment groove 17 is L-shaped. The top and side ends of the adjustment groove 17 pass through the top and side ends of the clamp 10, respectively. The clamping block 13 is slidably adapted in the adjustment groove 17, which provides a moving guide for the clamping block 13 and restricts the separation of the clamping block 13 from the clamp 10, thereby improving the connection effect between the clamping block 13 and the clamp 10.

[0027] Specifically, in this embodiment, rubber pads 18 are embedded in one side of the two clamping plates 15 that are attached to the display module 2. The elasticity of the rubber pads 18 provides protection for the display module 2 after it is clamped and fixed, preventing damage, and at the same time improving the stability of the display module 2 after it is clamped and fixed.

[0028] Specifically, in this embodiment, the air pipe of the air pump 8 is connected to the reserved detection hole of the display module 2 by a threaded connector, which facilitates the connection and separation between the air pump 8 and the display module 2, thereby facilitating the detection of different display modules 2.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
