Description

Technical Field

[0001] The utility model relates to the technical field of display back plates, and more specifically to a display back plate which is convenient for heat dissipation. Background Art

[0002] In today's digital and information age, monitors are used more and more widely. Whether in work, study or entertainment, people have higher requirements for the performance and stability of monitors. However, at present, most monitor back panels are equipped with exhaust fans, and the heat generated by the monitor during operation is dissipated with the help of the heat dissipation grid holes on the surface. However, after long-term use, dust will adhere to the inner wall of the heat dissipation grid holes, which may hinder the heat dissipation process.

[0003] In view of the above problem, after long-term use of the existing display back panel, dust will adhere to the inner wall of the heat dissipation grid hole, which may hinder the heat dissipation process. After a lot of searches, a display back panel that is easy to dissipate heat with patent number CN210515093U was found, including a display back panel, a rotating shaft is provided on the upper side of the display back panel, and two mounting rings symmetrical to the display back panel are sleeved on the outer end of the rotating shaft, an annular groove is cut at the outer end of the rotating shaft, and a cooperative ring is rotatably connected in the annular groove, and the cooperative ring is located on the left side of the mounting ring on the left side. The end of the mounting ring on the left side away from the display back plate is fixedly connected to a translation rod, a through hole matching the translation rod is bored at the outer end of the cooperative ring, a compression spring is fixedly connected between the cooperative ring and the mounting ring, a clamping rod is fixedly connected to the end of the mounting ring close to the display back plate, a clamping groove matching the clamping rod is bored at the outer end of the display back plate, and a pair of connecting seats are fixedly connected to the outer end of the rotating shaft, which can realize the removal of dust attached to the inner wall of the heat dissipation grid hole during the heat dissipation process, so that the heat can be dissipated in time; however, the technical solution provided by the patent has the following problems:

[0004] (1) The heat dissipation vents on the back panels of most monitors are of fixed size and cannot be adjusted. However, the heat dissipation requirements of monitors vary in different ambient temperatures. For example, in the summer when the temperature is high, a heat dissipation vent of a fixed size may be insufficient to meet the heat dissipation requirements. In the winter, the heat dissipation vent may be too large, causing the internal temperature of the monitor to be too low. This fixed-size heat dissipation vent cannot adapt to changes in ambient temperature, thus endangering the service life of the monitor.

[0005] (2) When installing the back panel of the display, screw holes are usually set at the four corners and the middle of the frame of the display, and then the back panel is installed by tightening the screws in sequence. However, tightening the screws requires the staff to carry appropriate tools such as screwdrivers at all times, which brings many inconveniences to the work and greatly reduces work efficiency.

[0006] The utility model can adjust the size of the heat dissipation opening to adapt to changes in different environments, which is convenient for heat dissipation of the display; and the back panel can be quickly disassembled and assembled without carrying additional tools, which greatly improves work efficiency.

[0024] The following will be combined with the attached embodiment of the utility model Figure 1-Figure 4 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0025] See also Figure 1-4 In an embodiment of the utility model, a display backplane that is easy to dissipate heat includes: a backplane 1, a connection box 3 is arranged on the outer end surface of the backplane 1, and this layout may be to concentrate some components related to heat dissipation and adjustment in the connection box 3 for unified management and operation, while not affecting the structure and function of the backplane 1 body. A plurality of vents are arranged at the connection between the backplane 1 and the connection box 3. The vents are arranged at the connection between the backplane 1 and the connection box 3, which helps to promote air circulation between the inside of the backplane 1 and the connection box 3, improve the heat dissipation efficiency, and better dissipate the heat generated inside the backplane 1. The heat dissipation port 11 is arranged on the outer surface of the connection box 3, and the four corners of the backplane 1 are respectively provided with disassembly and assembly components. The heat dissipation port 11 is arranged on the outer surface of the connection box 3, which can effectively discharge the hot air adjusted by the adjustment component to the external environment, ensuring the heat dissipation effect. The connection box 3 is provided with an adjustment component, and the disassembly and assembly components are arranged at the four corners of the backplane 1. Such a distribution can make the backplane 1 more evenly stressed during installation and disassembly, improve stability and reliability, and ensure that the connection between the backplane 1 and the display body is firm and easy to operate.

[0026] In the embodiment of the utility model, the adjustment assembly includes: a screw rod 14, a slider 15, a connecting rod 16, a screw rod 14, a moving rod 17, a rotating shaft 13 and an adjustment plate 10; the adjustment plate 10 is arranged inside the heat dissipation port 11, and the adjustment plate 10 is located inside the heat dissipation port 11, so that the adjustment plate 10 can directly control the opening and closing degree of the heat dissipation port 11. By rotating the adjustment plate 10, the effective ventilation area of ​​the heat dissipation port 11 is changed, so as to accurately adjust the ventilation volume and the heat dissipation effect, the rotating shaft 13 is fixedly connected to the two ends of the adjustment plate 10, the rotating shaft 13 is rotatably connected to the two ends of the heat dissipation port 11, the rotating shaft 13 is fixed to the two ends of the adjustment plate 10, and is rotatably connected to the two ends of the heat dissipation port 11, providing a stable rotation support point for the adjustment plate 10. It is ensured that the adjustment plate 10 can rotate around the rotating shaft 13 smoothly and flexibly to achieve the change of angle, the screw rod 14 is rotatably connected inside the connection box 3, and the screw rod 14 is rotatably connected inside the connection box 3. Such a layout enables the screw rod 14 to rotate in a stable environment and be protected by the connection box 3. At the same time, the connection box 3 provides a fixed position and space for the installation and operation of the screw rod 14. The slider 15 is threadedly connected to the outer surface of the screw rod 14. The slider 15 is threadedly connected to the outer surface of the screw rod 14. This matching mode makes it possible for the slider 15 to perform precise linear movement along the axial direction of the screw rod 14 due to the effect of the thread when the screw rod 14 rotates. Thus, the rotational movement of the screw rod 14 is converted into the linear displacement of the slider 15. The connecting rod 16 is fixedly connected to the left and right ends of the slider 15. The right end of the connecting rod 16 is fixedly connected to the upper end of the moving rod 17. The connecting rod 16 is fixed to the left and right ends of the slider 15 and connected to the upper end of the moving rod 17, thereby realizing the power transmission from the slider 15 to the moving rod 17. The linear motion of the slider 15 can drive the moving rod 17 to produce corresponding movements through the connecting rod 16. The moving rod 17 is connected to the inner end of the adjustment plate 10 through hinges. The moving rod 17 is connected to the inner end of the adjustment plate 10 through hinges. When the moving rod 17 moves up and down with the movement of the slider 15, it can apply a thrust or a pull to the adjustment plate 10 through the hinge, causing the adjustment plate 10 to rotate around the rotating shaft 13, thereby changing the size of the heat dissipation port 11.

[0027] In the embodiment of the utility model, the disassembly assembly comprises: an inner groove 6, a sleeve 7, a limit block 9 and a telescopic rod 2; the inner groove 6 is arranged inside the four corners of the back plate 1, and the inner groove 6 is arranged inside the four corners of the back plate 1, providing installation space for the sleeve 7, the telescopic rod 2 and other components, so that the disassembly assembly can be integrated inside the back plate 1 without affecting the appearance of the back plate 1 and the coordination with other components; the sleeve 7 is fixedly installed inside the inner groove 6, and the sleeve 7 is fixedly installed inside the inner groove 6, providing guidance and support for the telescopic movement of the telescopic rod 2, ensuring that the telescopic rod 2 can stably telescope in a specific direction; the telescopic rod 2 is telescopically connected inside the sleeve 7, and the limit block 9 is provided. The block 9 is fixedly connected to the outer surface of the telescopic rod 2, and the telescopic rod 2 is telescopically connected inside the sleeve 7, realizing the telescopic function, so that the telescopic rod 2 can be extended or retracted as needed, thereby realizing the matching or separation with the slot, and achieving the purpose of fixing or removing the back plate 1. The limit block 9 is slidably connected to the inner wall of the inner groove 6, limiting the telescopic range of the telescopic rod 2 in the sleeve 7, preventing the telescopic rod 2 from being excessively extended or retracted, and ensuring its normal operation. The limit block 9 is slidably connected to the inner wall of the inner groove 6, while ensuring the stable extension and retraction of the telescopic rod 2, it also limits the rotation of the telescopic rod 2, so that the telescopic rod 2 can only move along the axial direction, thereby ensuring that it can accurately match with the slot.

[0028] In the embodiment of the utility model, the spring 8 is arranged between the limit block 9 and the sleeve 7. This position arrangement enables the spring 8 to be compressed and stretched between the limit block 9 and the sleeve 7. When the telescopic rod 2 contracts inward, the limit block 9 will compress the spring 8, causing it to store elastic potential energy. When the external force disappears, the spring 8 releases the elastic potential energy and pushes the limit block 9, so that the telescopic rod 2 extends outward to achieve the function of automatic fixing. The spring 8 is wound around the outer ring of the telescopic rod 2. Such a layout can effectively utilize space and reduce the volume of the entire structure. At the same time, the spring 8 is wound around the outer ring of the telescopic rod 2 to ensure that the telescopic movement of the spring 8 is consistent with the axial movement of the telescopic rod 2, avoiding the spring 8 from being offset or twisted during the telescopic process, thereby stably providing elastic force and ensuring that the telescopic rod 2 can reliably perform telescopic movements to achieve the purpose of fixing or loosening the back plate 1.

[0029] In the embodiment of the utility model, the slide bar 5 is fixedly connected to one side surface of the limit block 9. By connecting the slide bar 5 to the limit block 9, when the slide bar 5 is pushed or pulled, the limit block 9 can be directly driven to move. Since the limit block 9 is fixedly connected to the telescopic rod 2, the telescopic rod 2 can be controlled to extend and retract in the sleeve 7. This design allows the operator to change the position state of the telescopic rod 2 by operating the slide bar 5 from the outside, thereby achieving the installation and removal operation of the back plate 1. As an interface for external operation, the slide bar 5 provides a convenient and intuitive control method for the operator, so that the operator can easily control the work of disassembling and assembling components.

[0030] In the embodiment of the utility model, the slide groove 4 is provided on the outer surface of the back plate 1, and the slide groove 4 is provided on the outer surface of the back plate 1, providing a track and space for the sliding of the slide rod 5, so that the movement of the slide rod 5 has a clear path and range, and the slide rod 5 is slidably connected inside the slide groove 4, so that when the operator applies force to the slide rod 5 from the outside, the slide rod 5 can slide smoothly along the slide groove 4. This design realizes the transmission of the external operating force to the internal disassembly and assembly components, thereby controlling the extension and retraction of the telescopic rod 2.

[0031] In the embodiment of the utility model, the rotating rod 12 is threadedly connected to the upper end of the connecting box 3, and the rotating rod 12 is threadedly connected to the upper end of the connecting box 3, so that the rotating rod 12 can maintain a stable position on the connecting box 3 and can rotate relative to the connecting box 3. The lower end of the rotating rod 12 is fixedly connected to the screw rod 14. This connection method enables the screw rod 14 to rotate synchronously when the rotating rod 12 rotates.

[0032] Working principle: First, when installing the back panel 1, first slide the slide bar 5 inward along the slide groove 4 to make the telescopic rod 2 fully extend into the inner groove 6. At this time, the spring 8 is in a compressed state. Then, embed the back panel 1 into the display. Finally, release the slide bar 5. Under the action of the rebound force of the spring 8, the telescopic rod 2 extends and inserts into the matching slot, thereby fixing the back panel 1 and the display. When removing the back panel 1, just slide the slide bar 5 inward along the slide groove 4 again until the telescopic rod 2 is fully extended into the inner groove 6. The back panel 1 can be quickly removed without carrying additional tools, which greatly improves work efficiency. When working in a low temperature environment such as winter, the rotating rod 12 can be rotated to rotate the screw rod 14. , so that the slider 15 drives the moving rod 17 to slide up and down on the surface of the screw rod 14. When the moving rod 17 moves upward, the adjusting plate 10 can be rotated to change the angle, so that the adjusting plate 10 gradually approaches the vertical position. At this time, the heat dissipation port 11 will gradually decrease, and the ventilation volume will also gradually decrease, which can prevent excessive heat from being lost too quickly; when working in a high temperature environment in summer, the rotating rod 12 is rotated, and the moving rod 17 moves downward until the adjusting plate 10 is in a horizontal position. At this time, the heat dissipation port 11 reaches the maximum, and the ventilation volume also reaches the maximum accordingly, so that the heat can be dissipated in time. By adjusting the size of the heat dissipation port 11 to adapt to changes in different environments, it is convenient for the display to dissipate heat.
