Description

Technical Field

[0001] This utility model belongs to the field of display screen technology, specifically referring to a cooling device for electronic display screens. Background Technology

[0002] With the continuous development of electronic technology, electronic displays have been widely used in various fields. However, electronic displays generate a lot of heat during long-term operation. If heat is not dissipated in time, the internal components of the display will become too hot, which will affect the display effect, shorten the service life, and may even cause malfunctions.

[0003] However, the structures of commonly available electronic display cooling devices are relatively fixed, often employing integrated, non-separable, or difficult-to-separate assembly methods. When internal components malfunction and require repair or replacement, the disassembly process is extremely cumbersome, often requiring various specialized tools and consuming significant time and effort. Furthermore, improper operation during disassembly can easily cause secondary damage to surrounding undamaged components, increasing repair costs, extending the downtime of the electronic display, affecting its normal operation, and causing considerable inconvenience to users. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing heat dissipation devices have relatively fixed structures, making disassembly inconvenient when internal equipment is damaged.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a cooling device using an electronic display screen, comprising a support base composed of a flat plate and support legs, a housing with a front opening rotatably above the support base, and a display screen installed inside the housing;

[0006] It also includes a through groove opened on the rear side wall of the housing, in which a heat sink is movably installed, a motor-driven cooling fan is installed on the heat sink, a fixing component is provided on the heat sink for installation, and exhaust windows are opened on both sides of the housing.

[0007] The front side of the housing is provided with a mounting groove, the display screen is movably placed in the mounting groove, and a positioning component is connected between the display screen and the mounting groove for fixing and limiting the display screen.

[0008] Furthermore, the fixing component includes a mounting block and a fixing screw. The mounting block is equidistantly disposed on the side wall of the heat sink, and the fixing screw is movably inserted into the mounting block and its end is threadedly connected to the housing.

[0009] Furthermore, the positioning component includes a frame and a positioning hole. The frame surrounds the outer wall of the display screen, and a fixing hole is provided on the frame. The positioning hole is provided on the side wall of the housing and its position coincides with the fixing hole. A positioning screw that is threadedly connected to the fixing hole is movably inserted into the positioning hole.

[0010] Furthermore, the heat sink is perforated, and filter screens are laid in all the perforations of the heat sink.

[0011] Preferably, a dustproof net is magnetically installed on the outer side of the exhaust window.

[0012] Preferably, a connecting shaft that rotates on a support is fixed to the bottom wall of the housing, and a motor that is axially connected to the connecting shaft is mounted on the support.

[0013] The beneficial effects achieved by adopting the above-described structure are as follows:

[0014] 1. By setting up mounting slots and positioning holes, and cooperating with the frame and fixing holes, the screen can be installed by plugging in positioning screws, which facilitates the installation and disassembly of the display screen. At the same time, by setting up through slots, heat dissipation brackets, mounting blocks and fixing screws, the heat dissipation fan can be disassembled and repaired, so that when problems occur inside the device, disassembly and repair can be carried out quickly. The operation is simple and avoids the difficulty of disassembling the integrated structure.

[0015] 2. By setting up a magnetic dust filter, it is easy to clean the dust filter and avoid clogging, which would affect the ventilation effect;

[0016] 3. By setting the click and connection axis, the angle of the housing can be adjusted to accommodate viewing from different screen orientations. Attached Figure Description

[0024] Example 1

[0025] like Figure 1-4 As shown, the present invention proposes a cooling device for an electronic display screen, comprising a support base 1 consisting of a flat plate and support legs, a housing 2 with a front opening rotatably above the support base 1, and a display screen 3 installed inside the housing 2, thereby providing support and protection for the display screen 3 using the housing 2.

[0026] like Figure 2 and 3 As shown, it also includes a through groove 4 opened on the rear side wall of the housing 2. A heat sink 5 is movably installed in the through groove 4. The heat sink 5 is hollowed out. A filter screen 17 is laid in the hollowed-out parts of the heat sink 5. A motor-driven cooling fan 6 is installed on the heat sink 5. A fixing component 7 is provided on the heat sink 5 for installing the heat sink 5. Exhaust windows 8 are opened on both sides of the housing 2. A dustproof net 18 is magnetically installed on the outside of the exhaust window 8. The fixing component 7 includes a mounting block 11 and a fixing screw 12. The mounting block 11 is equidistantly arranged on the side wall of the heat sink 5. The fixing screw 12 is movably inserted into the mounting block 11 and its end is threaded to the housing 2.

[0027] When the cooling fan 6 needs to be disassembled and inspected, the mounting block 11 can be released by removing the fixing bolts, so that the heat sink 5 can be pulled out from the through slot 4, which makes it convenient to repair and replace the cooling fan 6. The dust screen 18 and filter screen 17 can effectively filter dust and floating debris in the air during the ventilation process, preventing dust from entering the housing 2. The dust screen 18, which is installed by magnetic attraction, is easier to disassemble and clean.

[0028] like Figure 2 , 3 As shown in Figure 4, the front side of the housing 2 is provided with a mounting groove 9, and the display screen 3 is movably placed in the mounting groove 9. A positioning component 10 is connected between the display screen 3 and the mounting groove 9 to fix and limit the display screen 3. The positioning component 10 includes a frame 13 and a positioning hole 14. The frame 13 surrounds the outer wall of the display screen 3, and a fixing hole 15 is provided on the frame 13. The positioning hole 14 is opened on the side wall of the housing 2 and its position coincides with the fixing hole 15. A positioning screw 16 that is threadedly connected to the fixing hole 15 is movably inserted into the positioning hole 14.

[0029] When disassembling and assembling the display screen 3, remove the positioning screws 16 to release the restriction on the frame 13, and remove the display screen 3 from the mounting slot 9, which facilitates the maintenance of the display screen 3. The installation can be completed by reversing the operation. The structure is simple and the operation is convenient.

[0030] Example 2

[0031] like Figure 1 As shown, a connecting shaft 19 that rotates on a support base 1 is fixed to the bottom wall of the housing 2. A motor 20 that is axially connected to the connecting shaft 19 is installed on the support base 1. When it is necessary to adjust the rotation of the display screen 3, the motor 20 is started, which drives the connecting shaft 19 to rotate. The housing 2 is rotated by the connecting shaft 19, which can change the viewing direction of the display screen 3.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
