However, when installing the device through the adhesive strip, it is necessary to carefully align the device, and after the adhesion is completed, it is not easy to remove it, making the device inconvenient to install, increasing the labor burden of the operator, and the display will generate high temperature during operation, resulting in the adhesive strip being prone to losing its viscosity and causing the device to fall off.

[0005] Therefore, the utility model provides an anti-static backlight device to meet the requirements. Summary of the Utility Model

[0006] The utility model provides an anti-static backlight device, which can solve the problems in the prior art that during actual operation, it is necessary to carefully align the device, and after the adhesion is completed, it is not easy to remove it, making the device inconvenient to install, increasing the labor burden of the operator, and the display will generate high temperature during operation, resulting in the adhesive strip being prone to losing its viscosity and causing the device to fall off.

[0023] The following combines the drawings and specific embodiments to describe in detail an anti-static backlight device provided by the present utility model; at the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods.

[0024] As Figures 1 to 4 shown, the embodiment of the present utility model provides an anti-static backlight device, which includes a main body 1. An inner plate 2 is fixedly connected to the inner side of the main body 1. A plurality of slide seats 3 are fixedly connected to one side of the inner plate 2. A slide bar 4 is slidably connected to the inner side of the slide seat 3. A driving component 6 is used to drive the slide bar 4. The driving component 6 is connected to the slide bar 4. The number of the slide bars 4 is four, and they are evenly distributed on the outer side of the inner plate 2. A buckle 5 is fixedly connected to the top of the end of the slide bar 4 far from the driving component 6. One side of the top of the buckle 5 far from the driving component 6 is in a triangular convex shape. The driving component 6 includes a lower rotating seat 604 fixedly connected to the slide bar 4. The other end of the lower rotating seat 604 is rotatably connected to a rotating rod 603. The other end of the rotating rod 603 is rotatably connected to an upper rotating seat 602. The number of the upper rotating seats 602 is four, and they are annularly distributed on the outer side of the pressing plate 601. The pressing plate 601 is in transmission connection with the corresponding slide bar 4 through four rotating rods 603. The other end of the upper rotating seat 602 is fixedly connected to the pressing plate 601.

[0025] Orient the side of the device connected to the driving component 6 towards the installation part of the backlight panel of the display, then press the device in so that the pressing plate 601 contacts the bottom of the installation groove, and then push the surrounding sliding rods 4 through the rotating rod 603, so that under the limitation of the sliding seat 3, they move outward, thereby driving the buckle 5 to move outward and embed into the groove matching the installation part to complete the installation.

[0026] During installation, when the device is gently placed against the installation part of the backlight panel of the display, there is no need for cumbersome alignment or complex adjustment. This action will quickly be converted into mechanical energy and transmitted to the sliding rod 4, causing it to smoothly move outward along the sliding seat 3. This action is not only precisely controllable but also has uniform force, effectively avoiding the risk of damage caused by improper installation. Then, it is locked in the groove through the buckle 5 to prevent the device from loosening or falling due to vibration or external force during operation. This not only greatly reduces the complexity and operation difficulty during installation, enabling the operator to complete the installation work easily and quickly, but also fundamentally avoids the problem of the adhesive strip failing due to the high temperature generated when the display is working.

[0027] The four upper rotating seats 602 are all annularly distributed outside the pressing plate 601 and are connected to the corresponding lower rotating seats 604 and sliding rods 4. Therefore, this design ensures that the four sliding rods 4 can move outward at the same speed and in the same direction at the same time. It not only greatly simplifies the installation process and improves the installation efficiency, but also ensures the accuracy and stability of the installation.

[0028] As Figures 1 to 4 shown, conductive tubes 7 are fixedly connected to both the top and bottom of the main body 1. Pipe heads 8 are fixedly connected and communicated on both sides of the conductive tube 7. Conductive grooves 9 are provided inside the conductive tube 7 and the pipe head 8. A number of electricity-conducting blocks 10 are fixedly connected to the conductive tube 7. The number of electricity-conducting blocks 10 inside the same conductive tube 7 is three, and they are evenly distributed inside the conductive tube 7. The middle parts of the two conductive tubes 7 respectively penetrate through the top and bottom of the inner plate 2. An empty groove is provided on one side of the bottom of the main body 1. An external connection piece 11 is fixedly connected to the side of the inner plate 2 close to the empty groove, and an external connection groove is provided inside the external connection piece 11.

[0029] Connect it to an external display through the external connection piece 11 and connect the pipe head 8 to an external electricity-conducting structure. During operation, the static electricity on the inner plate 2 will be guided into the conductive tube 7, and then the conduction and dissipation of the static electricity will be enhanced through the conductive groove 9 and the electricity-conducting blocks 10 to ensure that the static electricity will not affect the backlight panel and the display.

[0030] The conductive tube 7 is made of a metal material with high electrical conductivity to ensure rapid and effective conduction of static electricity. It forms one or more continuous conductive paths that run through the entire device, providing a solid physical basis for the guidance and dissipation of static electricity. The conductive groove 9 is opened inside the conductive tube 7 and inside the tube head 8 connected thereto, and they constitute a continuous, low-impedance conductive channel. After static electricity is generated, it will quickly flow out of the conductive tube 7 through the conductive groove 9 and then be guided to a wider current-carrying structure. The current-carrying blocks 10, as a supplement and enhancement to the conductive groove 9, are evenly installed inside the conductive tube 7. These current-carrying blocks 10 not only increase the contact area between the conductive tube 7 and the static electricity source, improving the efficiency of static electricity conduction, but also optimize the flow path of static electricity inside the conductive tube 7 through their unique shape and layout, reducing the possibility of static electricity accumulation.

[0031] The working principle provided by the present utility model: Install the side of the device connected to the driving component 6 facing the installation part of the backlight panel of the display, and then press the device in so that the pressing plate 601 contacts the bottom of the installation groove. Then, push the surrounding sliding rods 4 through the rotating rod 603, so that under the limitation of the sliding seat 3, they move outward, thereby driving the buckle 5 to move outward and embed into the groove matching the installation part to complete the installation. Connect to an external display through the external connection piece 11, and connect the tube head 8 to an external current-carrying structure. During operation, the static electricity on the inner plate 2 will be guided into the conductive tube 7, and then the conduction and dissipation of static electricity will be enhanced through the conductive groove 9 and the current-carrying blocks 10 to ensure that static electricity will not affect the backlight panel and the display.

[0032] The present utility model covers any alternatives, modifications, equivalent methods, and solutions made to the essence and scope of the present utility model; in order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model, but those skilled in the art can fully understand the present utility model without these detailed descriptions.

[0033] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
