Description

Technical Field

[0001] The present invention relates to the technical field of display screens, and particularly to an LED display screen with a switchable installation method. Background Art

[0002] A display screen is an electronic device used to display images and texts, and is widely used in various places in life, such as TVs, computers, electronic billboards in shopping malls, etc. Among them, an LED display screen mainly achieves the display effect through light-emitting diodes, and has the advantages of simple process and low cost compared with other types of display screens.

[0003] In the prior art, a Chinese patent with the authorization announcement number of CN212491010U discloses a connection structure of a display screen and a display screen. The connection structure of the display screen includes two installation frames. Each installation frame has two side frames arranged oppositely, and the outer surface of the side frame is provided with an inclined surface that is inclined from front to back. The connection structure of the display screen further includes a first connecting member. The first connecting member is provided with a first limiting member, and the side frame is provided with a first installation hole for the first connecting member to pass through. The outer surface of the side frame is provided with a groove around the first installation hole, and the bottom wall of the groove constitutes an installation plane for abutting against the first limiting member. When the two installation frames are flatly connected in a planar shape, the first connecting member passes through the first installation hole to fixedly connect the two installation frames, and the first limiting member abuts against the installation planes of the two installation frames. In this way, when the splicing surface of the installation frame is completely an inclined surface, the problem that the two installation frames cannot be spliced or an auxiliary tool needs to be borrowed to splice the plane is solved, and the efficiency of splicing the planar display screen when the splicing surface is completely an inclined surface is improved.

[0004] During the use of the above-mentioned display screen, it is suspended and installed by using the installation frame, and the overall position is fixed after the suspension installation, which is not convenient for subsequent movement. For some special use cases, such as the advertising LED display screen used in a store, it is placed at the door during the day when the store opens, and is retracted into the room for anti-theft and rain protection reasons when the store is completely closed at night. In this case, the display screen that can only be suspended and installed cannot achieve a good use effect.

[0005] In the prior art, a Chinese patent with the authorization announcement number CN211699586U discloses a display screen protection board and a display screen, including a display body, characterized in that: an adjustment bracket is fixed at the center position of the rear end of the display body, and a protection board member is sleeved outside the display body, and support frames are fixed at both lower ends of the protection board member. A protective glass is embedded and fixed at the center position of the front surface of the protection board member, and a reserved groove is reserved at the lower right end of the protective glass. A cavity is formed inside the protection board member. Anti-collision strips are adhered to the left and right side surfaces inside the cavity. A magnifying lens is arranged on the front side of the protective glass, and adsorption blocks A are symmetrically fixed on both the left and right sides of the magnifying lens. A pen holder is fixed on the right side surface of the protection board member. A connection frame is arranged on the rear surface of the protective glass. This display screen protection board and display screen can be moved on the surface of the protective glass according to the needs of different people, facilitating the elderly to view the words on the screen.

[0006] During the long-term use of the above device, some dust will adhere to the surface (dust mixed in the air is adsorbed on the display screen surface under the action of static electricity). If this dust is not cleaned, it will block the overall brightness of the display screen, thereby affecting the viewing effect. Summary of the Invention

Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1-9 , the present invention provides a technical solution: an LED display screen with a switchable installation method.

[0039] Embodiment 1

[0040] In this embodiment, it is disclosed that: a display panel 1 with a square structure, a protective rear cover 2 is fixedly installed on the outer surface at the rear side of the display panel 1 by bolts. It further includes: a mounting plate 3 is fixedly installed on the outer surface of the protective rear cover 2, and a suspension mechanism is arranged on the upper side of the rear surface of the mounting plate 3. The device is suspended and installed by docking the suspension mechanism with a support column 5 fixedly installed on the wall; the suspension mechanism includes a suspension plate 4 fixedly installed with the mounting plate 3, and a plurality of positioning blocks 6 are fixedly installed on the lower surface of the suspension plate 4 at equal intervals. Moreover, the positioning blocks 6 and the hole structures formed on the surface of the support column 5 are in an insertion and engagement structure. Fixing bolts 7 are installed through the left and right sides of the suspension plate 4 to fix the support column 5 by using the fixing bolts 7. A support mechanism is arranged on the lower side of the rear surface of the mounting plate 3. The support mechanism includes a placement bottom plate 8 in a flat plate structure. The placement bottom plate 8 is rotated to a horizontal position to support the whole device, realizing the overall placement and installation; the support mechanism further includes a support rod 10 rotatably installed between the placement bottom plate 8 and the mounting plate 3. Moreover, a rubber anti-slip pad 9 is fixedly installed on the lower surface of the placement bottom plate 8. And a push rod 11 is rotatably installed at the middle position of the support rod 10. At the same time, a fixing rod 15 for fixing the placement bottom plate 8 in a horizontal state is installed by threading at the bottom end of the mounting plate 3. The support rod 10 and the push rod 11 are folded and stored inside a storage groove 12 on the outer surface of the mounting plate 3. And the top end of the push rod 11 is rotatably installed with a movable rod 13. Moreover, the movable rod 13 and the mounting plate 3 are slidably connected through penetration. At the same time, an adjustment screw rod 14 for driving its movement is installed by threading inside the movable rod 13.

[0041] When using the device, first determine the installation method (suspension installation or placement installation) according to actual usage needs. If it is fixed for a long time, then it is suspended and installed. At this time, a support column 5 is fixedly installed on the wall at the installation position. Then, the suspension plate 4 behind the protective rear cover 2 is snapped into the support column 5. At this time, the positioning blocks 6 below the suspension plate 4 are inserted into the holes on the upper surface of the support column 5 to form a snap fit. Then, the fixing bolts 7 on the left and right sides of the suspension plate 4 are rotated to fix the suspension plate 4 and the support column 5 by using the fixing bolts 7, realizing the suspension installation of the device; if it needs to be moved frequently, then choose placement installation. At this time, the adjustment screw rod 14 above the mounting plate 3 is rotated. When the adjustment screw rod 14 rotates, it drives the movable rod 13 outside it to slide downward relative to the mounting plate 3. When the movable rod 13 slides downward, it pushes the push rod 11 at its bottom end to move synchronously, so that the push rod 11 pushes the support rod 10 to rotate (the support rod 10 and the push rod 11 are stored inside the storage groove 12 when not in use to reduce the occupied space). Finally, the placement bottom plate 8 is rotated to a horizontal position by using the support rod 10. Then, the fixing rod 15 is screwed to thread-fix the bottom end of the fixing rod 15 and the placement bottom plate 8. At this time, the whole device can be placed and installed by using the placement bottom plate 8. The anti-slip pad 9 on the lower surface of the placement bottom plate 8 plays an anti-slip role.

[0042] Embodiment Two

[0043] This embodiment further discloses compared with the first embodiment: a buffer assembly is provided inside the suspension mechanism, and the buffer assembly is used to buffer and protect the connection part of the suspension mechanism. The buffer assembly includes a movable plate 19, and a rubber buffer pad 20 is fixedly installed on the upper surface of the movable plate 19. The movable plate 19 is elastically connected to the suspension plate 4 through a buffer spring 22. A permanent magnet 21 is fixedly installed on the lower surface of the movable plate 19, and an electromagnet 18 is fixedly installed on the side surface of the placement bottom plate 8. The magnetic poles between the permanent magnet 21 and the electromagnet 18 are opposite. A first metal contact 16 is fixedly installed on the outer surface of the placement bottom plate 8, and the first metal contact 16 is in contact with a second metal contact 17 fixedly installed on the outer surface of the mounting plate 3. When the first metal contact 16 and the second metal contact 17 are in contact, the power supply of the electromagnet 18 is turned on.

[0044] By adding the above structure, when the device is suspended and installed, the placement bottom plate 8 is received at a position where it fits with the mounting plate 3. At this time, the first metal contact 16 and the second metal contact 17 are in contact, thereby turning on the power supply of the electromagnet 18, causing the electromagnet 18 to generate magnetism. Using the magnetic repulsion force between the electromagnet 18 and the permanent magnet 21, the movable plate 19 is pushed upward, so that the buffer pad 20 above the movable plate 19 is in close contact with and squeezed against the support column 5. At this time, the elastic action of the rubber buffer pad 20 and the buffer spring 22 cooperate to achieve buffer protection for the connection position of the suspension plate 4, absorb energy when the device as a whole is impacted, and reduce damage.

[0045] Embodiment Three

[0046] This embodiment further discloses compared with the first and second embodiments: heat dissipation holes 23 arranged in a matrix are provided on the outer surface of the protective rear cover 2. The heat dissipation holes 23 are used in cooperation with the internal heat dissipation fan to dissipate heat from the whole device. Cleaning mechanisms for cleaning the heat dissipation holes 23 are provided on the left and right sides at the rear of the protective rear cover 2. The cleaning mechanisms include a cleaning brush 24 slidable on the protective rear cover 2 and a transmission lead screw 25 threadedly installed through the protective rear cover 2. The transmission lead screw 25 is used to drive the cleaning brush 24 to move up and down, and the positions of the cleaning brush 24 and a storage airbag 26 fixedly installed on the outer surface of the protective rear cover 2 correspond to each other up and down. The storage airbag 26 and a dust cleaning nozzle 27 form a communication structure through a connecting hose 28 fixedly installed on its side surface, and the dust cleaning nozzle 27 is fixedly installed on the left and right sides of the display screen panel 1.

[0047] By adding the above structure, during the use of the device, the heat dissipation holes 23 cooperate with the heat dissipation mechanism inside the protective rear cover 2 to achieve the purpose of overall heat dissipation. At the same time, the motor drives the transmission lead screw 25 to rotate regularly, so that the transmission lead screw 25 drives the cleaning brush 24 outside it to move up and down, so that the cleaning brush 24 cleans the surface of the heat dissipation holes 23, avoiding dust clogging the heat dissipation holes 23 and affecting the heat dissipation effect. And when the upper and lower cleaning brushes 24 move to the middle position at the same time, the storage airbag 26 is squeezed. At this time, the air inside the storage airbag 26 is ejected from the dust cleaning nozzle 27 through the connecting hose 28, so as to blow and clean the outer surface of the display screen panel 1 by using the air flow.
