Description

Technical Field

[0001] This utility model relates to the technical field of screen display, specifically to an assembled split-screen display device. Background Technology

[0002] In the prior art, multi-screen splicing systems for LCD displays typically use two sheet metal connectors installed on the back frame of the LCD display. Fixed bends are installed at both ends of the connectors, and nuts are riveted to the bends for fixing and adjusting the position of the back frame. The back frame in the prior art is usually assembled from industrial aluminum profiles or welded from triangular iron and square steel pipes.

[0003] During installation, screws and rivets are used to securely connect the LCD screen and the back frame. While this method can fix a single LCD screen, in multi-screen splicing systems where installation space is limited and maintenance space is scarce, a locking-type standard splicing frame is typically used. After installation, a large amount of space is left on the side for disassembly. Furthermore, when all the screens are turned on, they generate a lot of heat, and the single-panel structure will affect its heat dissipation and ventilation, thus affecting the lifespan of the screen. Utility Model Content

[0004] The purpose of this invention is to provide an assembled split-screen display device to solve the above-mentioned defects caused by the prior art.

[0005] An assembled split-screen display device includes a device housing, a straight display screen, a back support, and an axial flow fan. Curved screens are symmetrically arranged on the outer side of the device housing, and straight display screens are symmetrically distributed in the middle of the device housing. A switching mechanism is provided inside the device housing to adjust the position of the straight display screens according to the installation requirements and dimensions of the two sets of straight display screens. A ventilation mechanism is provided above the switching mechanism to draw outside air into the device housing. The device housing then exhausts hot air through suction mesh plates on both sides of its bottom, thus achieving ventilation and cooling for both the curved and straight display screens.

[0006] Preferably, the switching mechanism includes positioning holes, a back support, a guide rail, a slider, an internal threaded tube, and an external threaded rod. The positioning holes are equally spaced on the outer side of the back support. Sliders are provided on both the upper and lower sides of the back support. The outer side of the slider is connected to the guide rail. The guide rail is equally spaced on the outer side of two sets of partition plates. The other side of the internal threaded tube is connected to the back of the back support by a bearing. The back support is connected to the back of the display screen through the equally spaced positioning holes. The back support is positioned between the two sets of partition plates.

[0007] Preferably, the device housing is connected to the inner end of the internally threaded tube via an externally threaded rod located on the back.

[0008] Preferably, the ventilation mechanism includes an air intake screen, a positioning groove, a partition plate, an axial flow fan, and a paper filter element. The air intake screen is symmetrically arranged on both sides of the equipment housing. The partition plate is symmetrically arranged inside the equipment housing. The positioning groove is equally spaced on the outer side of the partition plate. The paper filter element is fitted into the inner end of the positioning groove. The axial flow fan is symmetrically arranged at the top of the equipment housing.

[0009] Preferably, the separator is connected to the outside of the paper filter element through equally spaced positioning slots.

[0010] Preferably, the device housing is connected to the input end of the axial flow fan via an air intake mesh plate that runs through one side.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The upper and lower sides of the back bracket are positioned by guide rails with equal spacing. On the one hand, according to the installation requirements of the display screen, the back bracket is pushed out laterally into the equipment housing, which facilitates the assembly of the back bracket and the back of the display screen. On the other hand, the back bracket is moved laterally by the external threaded rod. According to the thickness of the display screen, the displacement and installation size of the display screen are adjusted to reduce the error between the two sets of display screens and improve the display effect.

[0013] 2. By using equally spaced partitions, the efficiency of supporting multiple displays is improved, and the airflow rate of the axial fans on both sides is increased. The air is filtered by a paper filter before being injected into the next layer of space, reducing the amount of dust adhering to the back of the display and thus enhancing heat dissipation efficiency.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, an assembled split-screen display device includes a device housing 1, a straight display screen 4, a back support 6, and an axial flow fan 13. Curved screens 3 are symmetrically arranged on the outer side of the device housing 1, and straight display screens 4 are symmetrically distributed in the middle of the device housing 1. A switching mechanism 7 is provided inside the device housing 1 to adjust the position of the straight display screens 4 according to the installation requirements and size of the two sets of straight display screens 4. A ventilation mechanism 10 is provided above the switching mechanism 7 to draw outside air into the device housing 1. The device housing 1 discharges hot air through suction mesh plates 2 on both sides of its bottom, thus completing the ventilation and cooling of the curved screens 3 and the straight display screens 4.

[0023] In this embodiment, the switching mechanism 7 includes positioning holes 5, a back support 6, a guide rail 8, a slider 9, an internal threaded tube 15, and an external threaded rod 16. The positioning holes 5 are evenly spaced on the outer side of the back support 6. Slider 9s are provided on both the upper and lower sides of the back support 6. The outer side of the slider 9 is connected to the guide rail 8. The guide rail 8 is evenly spaced on the outer side of two sets of partition plates 12. The other side of the internal threaded tube 15 is bearing-connected to the back of the back support 6. The back support 6 is connected to the back of the display screen 4 through the evenly spaced positioning holes 5. The back support 6 is positioned between the two sets of partition plates 12. The guide rail 8 is evenly spaced to position the two sides of the back support 6, thereby switching the installation position of the back support 6 according to the size of the display screen.

[0024] In this embodiment, the device housing 1 is connected to the inner end of the internal threaded tube 15 via an external threaded rod 16 on the back. By utilizing the screw pair between the external threaded rod 16 and the internal threaded tube 15, the rotational motion can be converted into axial linear motion, thereby dynamically adjusting and displacing the display screen 4.

[0025] In this embodiment, the ventilation mechanism 10 includes an air intake screen 2, a positioning groove 11, a partition plate 12, an axial flow fan 13, and a paper filter element 14. The air intake screen 2 is symmetrically arranged on both sides of the equipment housing 1. The partition plate 12 is symmetrically arranged inside the equipment housing 1. The positioning groove 11 is equally spaced on the outer side of the partition plate 12. The paper filter element 14 is attached to the inner end of the positioning groove 11. The axial flow fan 13 is symmetrically arranged at the top of the equipment housing 1. The axial flow fan 13 filters the outside air and then draws it in, thereby reducing the dust content in the flowing air and preventing dust from affecting the heat dissipation of the display screen 4.

[0026] In this embodiment, the partition plate 12 is connected to the outside of the paper filter element 14 through equally spaced positioning slots 11, and the flow of gas in the paper filter element 14 is slowed down and air is filtered by equally spaced slots.

[0027] In this embodiment, the device housing 1 is connected to the input end of the axial flow fan 13 through the air intake mesh 2 provided on one side. The axial flow fan 13 is used to draw in air, and the air intake mesh 2 provided on both sides is used to directly discharge the hot air into the device housing 1.

[0028] In practical applications, this type of modular split-screen display device includes the following tasks:

[0029] Step 1: During use, first install the curved screen 3 onto the frame hook position in sequence, fix it with precision screws, and use anti-loosening washers to prevent displacement caused by vibration. Alternatively, the frame can be fixed on the slider 9, and the frame and curved screen 3 can be moved or disassembled by pulling the slider 9. During installation, the curved screen 3 is made to fit against the outside of the equipment shell 1. The contact points between the curved screen 3 and the equipment shell 1 are bonded and protected with sealing strips. Then, the paper filter element 14 is installed inside the positioning through groove 11, thereby blocking the positioning through groove 11 that is equally spaced on the outside of the partition plate 12.

[0030] Step 2: The operator first rotates the external threaded rod 16 (the external threaded rod 16 and the internal threaded tube 15 are connected by a helical pair, and the rotational motion can be converted into axial linear motion) to make the internal threaded tube 15 move outside the external threaded rod 16, thereby pushing the back bracket 6. The sliders 9 set on both sides of the back bracket 6 move outside the guide rail 8 (since the width of the sliders 9 is greater than the width of the back bracket 6, the back bracket 6 can protrude from the equipment housing 1 for installation) so that the positioning hole 5 on the outer side of the back bracket 6 fits with the vertical display screen 4. Fasteners are used to secure it. After rotating the external threaded rod 16 in the opposite direction, the back bracket 6 and the vertical display screen 4 fit against the surface of the equipment housing 1, completing the installation.

[0031] Step 3: After the installation of the straight display screen 4 is completed, turn on the axial flow fan 13 on one side and use the suction screen 2 set on one side to draw in the outside air. After the suction screen 2 filters the large foreign objects in the air, it is introduced into the interior of the equipment shell 1. The flowing air carries away the heat of the top arc screen 3. The air is then filtered a second time through the paper filter element 14 on the outside of the partition plate 12.

[0032] Step 4: After secondary filtration, the air is directly introduced to the back of the lower straight display screen 4 to dissipate heat from it. Finally, the air is introduced to the back of the lower curved screen 3 for heat dissipation. (Depending on actual usage needs, another set of axial flow fans 13 can also be turned on to improve the heat dissipation effect on the straight display screen 4 and the lower curved screen 3.) The hot air is discharged and replaced by the air intake mesh 2 set on both sides of the equipment housing 1, thus completing the cooling treatment of the curved screen 3 and the straight display screen 4 in the equipment housing 1.

[0033] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
