Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a display screen capable of suppressing electromagnetic interference. Background Art

[0002] With the continuous development of electronic technology, various electronic devices are being used more and more widely. These electronic devices will generate electromagnetic interference when working, affecting the surrounding electronic devices. Especially in some occasions with high requirements for electromagnetic interference, such as medical equipment, aerospace equipment, etc., electromagnetic interference will have a serious impact on the normal operation of the equipment.

[0003] In the prior art, in order to achieve the electromagnetic suppression effect, the traditional display screen is usually installed in a shielding cover. However, since more electrical components need to be installed in the shielding cover, in order to avoid damage caused by excessive temperature, it is usually necessary to open heat dissipation holes on the shielding cover for heat dissipation. However, after the heat dissipation holes are opened, their sealing is poor, which will affect the electromagnetic suppression effect. Therefore, the utility model proposes a display screen with electromagnetic interference suppression to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to provide a display screen capable of suppressing electromagnetic interference.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A display screen with electromagnetic interference suppression, comprising a shielding cover body, a display screen body mounted on the shielding cover body, a heat dissipation mechanism for dissipating heat inside the shielding cover body provided on the rear wall of the shielding cover body, the heat dissipation mechanism comprising a radiator body fixedly connected to the rear wall of the shielding cover body, a plurality of heat dissipation fins arranged at equal intervals provided inside the radiator body, a circulating air pump installed on the rear wall of the shielding cover body, the radiator body and the upper end of the shielding cover body are connected through an air inlet pipe, the circulating air pump and the lower end of the radiator body are connected through a connecting pipe, the air inlet pipe is connected to the connecting pipe, and the lower end of the circulating air pump and the lower end of the shielding cover body are connected through an exhaust pipe.

[0007] Preferably, a fixing block is fixedly connected to the rear wall of the shielding cover body, and a sliding rod is slidably connected to the fixing block.

[0008] Preferably, a slide groove is provided on the rear wall of the shielding cover body, a moving block is slidably connected in the slide groove, and the lower end of the moving block is fixedly connected to the upper end of the sliding rod.

[0009] Preferably, a fixing plate is fixedly connected to the rear wall of the shielding cover body, a threaded rod is rotatably connected through the fixing plate, and the threaded rod passes through the moving block and is threadedly connected thereto.

[0010] Preferably, a turntable is fixedly connected to the upper end of the threaded rod, and a non-slip rubber sleeve is provided on the turntable.

[0011] Preferably, the lower end of the sliding rod is fixedly connected to a base, and the base is designed to be disc-shaped.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting up a heat dissipation mechanism, the circulating air pump is started when in use. The circulating air pump draws the hot air in the shielding cover body from the air inlet pipe, passes through the heat dissipation fins inside the radiator body, cools the hot air in the air inlet pipe, and then enters the connecting pipe and is input into the shielding cover body from the exhaust pipe, thereby achieving heat dissipation inside the shielding cover body. There is no need to open heat dissipation holes, ensuring the sealing of the shielding cover body and improving the electromagnetic suppression effect.

[0014] 2. By setting a threaded rod and a moving block, rotating the turntable drives the threaded rod to rotate, thereby driving the moving block threadably connected to it to move in the slide groove, and then driving the sliding rod to slide in the fixed block. The movement of the sliding rod can drive the base to move, thereby adjusting the distance between the base and the display screen body, facilitating the adjustment of the height of the display screen body, and facilitating the use of people of different heights, thereby greatly improving the practicality of the device.

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0020] Reference Figure 1-3 , a display screen with electromagnetic interference suppression, comprising a shielding cover body 16, a display screen body 2 is installed on the shielding cover body 16, a heat dissipation mechanism for dissipating heat inside the shielding cover body 16 is arranged on the rear wall of the shielding cover body 16, the heat dissipation mechanism comprises a radiator body 4 fixedly connected to the rear wall of the shielding cover body 16, a plurality of heat dissipation fins 13 arranged at equal intervals are arranged inside the radiator body 4, a circulating air pump 5 is installed on the rear wall of the shielding cover body 16, the radiator body 4 is connected to the upper end of the shielding cover body 16 through an air intake pipe 10, the circulating air pump 5 is connected to the lower end of the radiator body 4 through a connecting pipe 12, the air intake pipe 10 is connected to the connecting pipe 12, and the lower end of the circulating air pump 5 is connected to the lower end of the shielding cover body 16 through an exhaust pipe 6. It should be noted that the shielding cover body 16 is a copper-aluminum dense shell, which can shield the influence of external electromagnetic waves on the internal circuit and the electromagnetic waves generated inside from radiating outward. This device does not need to open heat dissipation holes for heat dissipation, which can greatly improve the electromagnetic suppression effect of the device.

[0021] In the utility model, a fixed block 7 is fixedly connected to the rear wall of the shielding cover body 16, and a sliding rod 15 is slidably connected to the fixed block 7. A sliding groove 14 is provided on the rear wall of the shielding cover body 16, and a moving block 11 is slidably connected in the sliding groove 14. The lower end of the moving block 11 is fixedly connected to the upper end of the sliding rod 15. A fixed plate 9 is fixedly connected to the rear wall of the shielding cover body 16, and a threaded rod 8 is rotatably connected to the upper part of the fixed plate 9. The threaded rod 8 passes through the moving block 11 and is threadedly connected thereto. The sliding groove 14 can limit the moving block 11, greatly improving its movement stability. When moving, it can drive the sliding rod 15 and the base 1 to move, thereby achieving an adjustment effect.

[0022] In the utility model, the upper end of the threaded rod 8 is fixedly connected to the turntable 3, and the turntable 3 is covered with an anti-skid rubber sleeve. The anti-skid rubber sleeve is soft in texture and has good anti-skid properties, which is convenient for holding and rotating. The lower end of the sliding rod 15 is fixedly connected to the base 1, and the base 1 is disc-shaped. The disc-shaped base 1 can support the display screen body 2 and the shielding cover body 16, which is an existing mature technology and will not be elaborated here.

[0023] When the utility model is used, when heat is first dissipated, the circulating air pump 5 is started. The circulating air pump 5 can draw the hot air in the shielding cover main body 16 into the air intake pipe 10. After the hot air passes through the radiator main body 4, the heat dissipation fins 13 can cool the air intake pipe 10, thereby realizing cooling of the hot air in the air intake pipe 10. The air after cooling enters the exhaust pipe 6 and is discharged into the shielding cover main body 16 again through the exhaust pipe 6. In this way, the hot air generated in the shielding cover main body 16 can be continuously circulated and cooled, thereby realizing heat dissipation inside. There is no need to open heat dissipation holes on the shielding cover main body 16, which can improve the sealing performance of the shielding cover main body 16. When it is necessary to adjust the height of the display screen main body 2, the turntable 3 can be rotated to drive the threaded rod 8 to rotate, thereby driving the moving block 11 threadedly connected thereto to move, thereby driving the sliding rod 15 and the base 1 at the lower end of the sliding rod 15 to move, and adjusting the distance between the base 1 and the shielding cover main body 16, thereby realizing adjustment of the height of the display screen main body 2, which is convenient for people of different heights to use.
