Description

Technical Field

[0001] The present application relates to the technical field of LED light display screens, and in particular to an LED light display screen that is easy to assemble and disassemble. Background Art

[0002] LED light display is an electronic display device that uses light-emitting diodes as display units. This display is composed of thousands of LED lamp beads, which can display various texts, graphics, images, animations and video content in a specific arrangement order and color combination. LED display screens have been widely used in outdoor advertising, indoor information display, traffic signs, sports events, stage backgrounds, monitoring systems and other scenarios due to their high brightness, low power consumption, long life, fast response time and easy maintenance.

[0003] The LED light display screen is composed of a plurality of display units. Currently, when the LED light display screen is installed in front of a wall, the mounting frame is first fixed in front of the wall, and then the display unit is fixed to the mounting frame by screws. When the display unit is damaged, the damaged display unit needs to be disassembled and repaired.

[0004] To disassemble the display unit, an operator needs to enter the space between the wall and the mounting frame, and remove the screws on the damaged display unit from the back of the mounting frame to disassemble the damaged display unit, which makes the disassembly process more troublesome. In addition, a large space needs to be reserved between the wall and the mounting frame so that the operator can pass through, resulting in a waste of space. Summary of the invention

[0005] In order to improve the convenience of disassembly and assembly of the display unit, the present application provides an LED light display screen that is easy to disassemble and assemble, and can save space between the wall and the mounting frame.

[0006] The present application provides an LED light display screen that is easy to assemble and disassemble, which adopts the following technical solution:

[0007] An LED light display screen that is easy to disassemble and assemble comprises a mounting plate, wherein lamp beads are mounted on the front of the mounting plate, and the lamp beads are used to present images that need to be displayed on the display screen; a magnetic block is arranged on the back of the mounting plate, and the magnetic block is connected to a mounting frame through magnetic force.

[0008] By adopting the above technical solution, the magnetic block is magnetic, and the magnetic block is sucked on the side of the mounting bracket, thereby improving the connection stability between the mounting plate and the mounting bracket. Compared with the prior art, the mounting plate and the mounting bracket are fixed by screws. In the present application, the mounting bracket and the mounting plate are connected by magnetic attraction. When the display unit is damaged and needs to be repaired, the operator can apply an outward force to the mounting plate from the front of the mounting plate to disassemble the display unit, thereby improving the convenience of disassembly and assembly between the display unit and the mounting bracket. Therefore, the mounting bracket can be fitted with the wall, thereby saving space between the wall and the mounting bracket.

[0009] Preferably, a mounting bar is installed in front of the mounting plate, and the lamp beads are installed on the outer side of the mounting bar. There are multiple mounting bars, and the multiple mounting bars are distributed along the horizontal direction of the mounting plate, and a flow groove is opened between two adjacent mounting bars.

[0010] By adopting the above technical solution, the overall weight of the mounting plate can be reduced under the action of the circulation groove, and at the same time, materials can be saved. In addition, when it rains, rainwater can drip along the circulation groove, thereby reducing the accumulation of rainwater on the surface of the mounting plate.

[0011] Compared with the situation where two adjacent mounting strips are seamlessly connected, a plurality of mounting strips are assembled to form a rectangular plate, so that after water drops onto the surface, it needs to flow along the surface to the bottom surface until the water drops onto the ground. In the process of water droplets flowing on the surface of the mounting strip, more water marks will remain on the surface, which is more likely to cause surface water accumulation, and surface water accumulation will damage the LED lamp. In the present application, the flow groove between two adjacent mounting strips has a waterproof effect. Under the action of the flow groove, rainwater drips from the flow groove, so that less water droplets remain on the surface of the mounting strip. In addition, the flow groove makes the ventilation between the mounting strips better, so that the water on the surface of the mounting strip can be dried faster, thereby reducing the time that water marks on the surface of the mounting strip stay, thereby further reducing the situation of surface water accumulation on the mounting strip.

[0012] Preferably, a locking column is rotatably connected to the back side of the mounting bar.

[0013] By adopting the above technical solution, the other end of the locking column is inserted into the locking groove of the mounting frame. When the long side direction of the locking column is perpendicular to the long side direction of the mounting strip, it is in a locked state. At this time, the connection between the mounting plate and the mounting frame is more stable, thereby reducing the situation where the mounting plate falls from the side wall of the mounting frame.

[0014] When a display unit is damaged and needs to be disassembled for repair or replacement, the operator first inserts the disassembly tool into the circulation slot. The disassembly tool is a column with a diameter smaller than the width of the circulation slot, so that the disassembly tool can pass through the circulation slot. The circulation slot into which the disassembly tool is inserted is covered by the locking column. The disassembly tool is then moved along the circulation slot. When the disassembly tool contacts the locking column, force is continued to be applied to the disassembly tool to rotate the locking column until the long side of the locking column is parallel to the long side of the mounting strip. At this time, the locking column is in an open state. The operator applies outward force to the mounting plate to remove the locking column from the locking slot of the mounting frame, thereby disassembling the display unit. In addition, the operator can disassemble in front of the mounting plate, thereby saving space between the wall and the mounting frame.

[0015] Preferably, a power plug is provided on the back of the mounting plate, a waterproof groove is opened on the back of the mounting plate, the waterproof groove is located outside the power plug, a sealing ring is sleeved on the outer wall of the power plug, and the sealing ring is inserted into the waterproof groove.

[0016] By adopting the above technical solution, when the power plug is inserted into the slot for charging, one side of the power plug is pressed against the outer wall of the sealing ring. The sealing ring has elastic characteristics. When the sealing ring is pressed against the power plug, the sealing ring can fill the joint or gap between the power plug and the power plug post to form a physical barrier, reducing moisture from entering the device through these openings, thereby achieving a waterproof effect.

[0017] Preferably, the surface of the mounting bar on one side close to the lamp beads is covered with a waterproof layer.

[0018] By adopting the above technical solution, under the action of the waterproof layer, the waterproof layer can reduce the entry of rainwater, moisture or water into the interior of the display screen, protect the circuit board and electronic components from moisture erosion, thereby reducing short circuits, corrosion or other damages caused by moisture.

[0019] Preferably, a handle is installed on the back side of the mounting bar.

[0020] By adopting the above technical solution, when the operator needs to lift the display unit, the operator lifts the handle to lift the entire display unit, and the display unit is more convenient to pick up with the help of the handle.

[0021] Preferably, a vacant groove is formed on a side of the locking column away from the mounting bar.

[0022] By adopting the above technical solution, the weight of the locking column can be reduced under the action of the empty groove, so that when the disassembly tool rotates the locking column, the force applied by the operator is smaller, thereby facilitating better rotation of the locking column. At the same time, it can also save the material used for the locking column and reduce costs and resources.

[0023] Preferably, a support bar is provided between two adjacent mounting bars.

[0024] By adopting the above technical solution, under the action of the support bar, the structural stability of the installation bar can be improved, and the installation bar is less likely to break due to a large span, thereby increasing the service life of the display unit.

[0025] Preferably, a shielding shed is provided on the outer side of the mounting bar, and the shielding shed is located on the top of the lamp bead.

[0026] By adopting the above technical solution, when it rains outdoors, rainwater drops on the top surface of the shelter, then flows downward along the top surface of the shelter, and finally drops from the top surface of the shelter. The shelter plays a role of blocking water. Under the effect of the shelter, it can play a role of waterproofing and reduce the accumulation of water in the lamp beads.

[0027] Preferably, the processing step of processing one side of the mounting plate into an inclined surface is:

[0028] S1: Rectangular mounting plate processing: Process the raw material through a bending machine or a mold to process the raw material plate into a rectangular mounting plate;

[0029] S2: Inclined surface processing: Place the processed rectangular mounting plate on the top surface of the cutting work platform, and use the cutting equipment to cut one side of the mounting plate to cut one side of the mounting plate into an inclined surface.

[0030] By adopting the above technical solution, when the mounting plate is a rectangular plate, multiple mounting plates are assembled to form a display screen in the same plane. When a certain angle needs to be formed between two display screens, one side of the mounting plate is an inclined surface of the corresponding angle, so that after the two inclined surfaces are assembled, two display screens with the corresponding angle can be formed.

[0031] Compared with the prior art, when a mounting plate with an inclined surface is required, two sets of molds are needed to process the mounting plate. One side of the mounting plate is processed into an inclined surface by using two sets of molds, which makes it more troublesome to process one side of the mounting plate into an inclined surface, and the processing takes a long time. The number of mounting plates that require inclined surfaces is small, and the required number is the number of mounting plates in two vertical columns at the junction of two display screens. Therefore, the mounting plates that need to be produced in large quantities are rectangular mounting plates. Therefore, in the embodiment of the present application, rectangular mounting plates are first produced uniformly. When a mounting plate with an inclined surface is required, the uniformly produced rectangular mounting plates are cut by a cutting device, which makes it more convenient to process one side of the mounting plate into an inclined surface, thereby improving the production efficiency of processing one side of the mounting plate into an inclined surface.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. The magnetic block is magnetic, and the magnetic block is attracted to the side of the mounting frame, thereby improving the connection stability between the mounting plate and the mounting frame. Compared with the prior art, the mounting plate and the mounting frame are fixed by screws. In the present application, the mounting frame and the mounting plate are connected by magnetic attraction. When the display unit is damaged and needs to be repaired, the operator can apply an outward force to the mounting plate from the front of the mounting plate to disassemble the display unit, thereby improving the convenience of disassembly and assembly between the display unit and the mounting frame. Therefore, the mounting frame can be fitted to the wall, thereby saving space between the wall and the mounting frame.

[0034] 2. When a display unit is damaged and needs to be disassembled for repair or replacement, the operator first inserts the disassembly tool into the circulation slot. The disassembly tool is a column with a diameter smaller than the width of the circulation slot, so that the disassembly tool can pass through the circulation slot. The circulation slot into which the disassembly tool is inserted is covered by the locking column. The disassembly tool is then moved along the circulation slot. When the disassembly tool contacts the locking column, force is continued to be applied to the disassembly tool to rotate the locking column until the long side of the locking column is parallel to the long side of the mounting strip. At this time, the locking column is in an open state. The operator applies outward force to the mounting plate to remove the locking column from the locking slot of the mounting frame, thereby disassembling the display unit. In addition, the operator can disassemble in front of the mounting plate, thereby saving space between the wall and the mounting frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is combined with Figure 1-3 This application is described in further detail.

[0040] The embodiment of the present application discloses an LED light display screen that is easy to assemble and disassemble.

[0041] Reference Figure 1A LED light display screen that is easy to disassemble and assemble includes a display unit, which is installed on the side wall of a mounting frame. There are multiple display units, and the multiple display units are arranged and attached along the side wall of the mounting frame. After the multiple display units are assembled, a display screen is formed.

[0042] Reference Figure 1 and Figure 2 The display unit includes a mounting plate 1, a placement groove is opened through the side wall of the mounting plate 1, a mounting bar 11 is fixed to the side wall of the mounting plate 1, the mounting bar 11 is vertically arranged, there are multiple mounting bars 11, and the multiple mounting bars 11 are evenly distributed along the horizontal direction of the mounting plate 1, a mounting groove is opened on the outer side of the mounting bar 11, and a lamp bead 12 is fixed on the outer side of the mounting bar 11. In the embodiment of the present application, the lamp bead 12 is an LED lamp, the lamp bead 12 is located in the mounting groove, there are multiple mounting grooves, and the multiple mounting grooves are evenly distributed along the long side direction of the mounting bar 11, the number of the lamp bead 12 is adapted to the number of the mounting grooves, and the lamp bead 12 corresponds to the mounting grooves one by one.

[0043] A shielding shed 13 is fixed on the outer side of the mounting strip 11. The shielding shed 13 is located on the top of the lamp beads 12. The number of the shielding sheds 13 is adapted to the number of the lamp beads 12. The top surface of the shielding shed 13 is an inclined surface, and the inclination direction is from top to bottom and outward. Correspondingly, the bottom surface of the shielding shed 13 is also an inclined surface, and the inclination direction is from top to bottom and inward, so that the top surface of the shielding shed 13 and the bottom surface of the shielding shed 13 are symmetrically arranged. When it rains outdoors, rainwater drips on the top surface of the shielding shed 13, and then the rainwater flows along the top surface of the shielding shed 13 to a lower place, and finally drips from the top surface of the shielding shed 13. The shielding shed 13 plays a role of water blocking. Under the action of the shielding shed 13, it can play a role of waterproofing, thereby reducing the accumulation of water in the lamp beads 12.

[0044] A plurality of mounting strips 11 evenly divide the placement groove so that a flow groove 14 is formed between two adjacent mounting strips 11. Under the action of the flow groove 14, the overall weight of the mounting plate 1 can be reduced. At the same time, materials can also be saved. Moreover, when it rains, rainwater can drip along the flow groove 14, thereby reducing the accumulation of rainwater on the surface of the mounting plate 1.

[0045] Compared with the situation where two adjacent mounting strips are seamlessly connected, a plurality of mounting strips are assembled to form a rectangular plate, so that after water drops onto the surface, it needs to flow along the surface to the bottom surface until the water drops onto the ground. In the process of water droplets flowing on the surface of the mounting strip, more water marks will remain on the surface, which is more likely to cause surface water accumulation, and surface water accumulation will damage the LED lamp. In the present application, the flow groove 14 between two adjacent mounting strips 11 has a waterproof effect. Under the action of the flow groove 14, rainwater drips from the flow groove 14, so that less water droplets remain on the surface of the mounting strip 11. In addition, the flow groove 14 makes the ventilation between the mounting strips 11 better, so that the water on the surface of the mounting strip 11 dries faster, thereby reducing the time that water marks on the surface of the mounting strip 11 stay, thereby further reducing the situation of surface water accumulation on the mounting strip 11.

[0046] Reference Figure 3 A support bar 15 is fixed between two adjacent mounting bars 11. There are multiple support bars 15, and the multiple support bars 15 are distributed along the long side direction of the flow slot 14. The support bars 15 play the role of supporting the mounting bars 11. Under the action of the support bars 15, the structural stability of the mounting bars 11 can be improved, and the situation in which the mounting bars 11 are more likely to break due to a large span can be reduced, thereby increasing the service life of the display unit.

[0047] Ribs 16 are fixed to both ends of the mounting bar 11. The ribs 16 are right-angled triangular plates. One right-angled side of the ribs 16 is fixed to the back of the mounting bar 11, and the other right-angled side of the ribs 16 is fixed to one side of the mounting plate 1. Under the action of the ribs 16, the ribs 16 can increase the overall strength and rigidity of the mounting bar 11 structure, especially when subjected to bending, shearing and torsional forces. The ribs 16 provide additional support points to help disperse and transfer the load, which can reduce the excessive deformation or instability of the mounting bar 11 when subjected to force, thereby maintaining the geometric shape and stability of the mounting bar 11.

[0048] The side of the mounting plate 1 close to the lamp bead 12 is the front, and the side of the mounting plate 1 away from the lamp bead 12 is the back. A connecting groove is provided on the back of the mounting plate 1. The display unit also includes a magnetic block 2, which is inserted into the connecting groove. There are multiple connecting grooves, which are distributed around the mounting plate 1. Correspondingly, the number of the magnetic blocks 2 is adapted to the number of the connecting grooves. The magnetic blocks 2 correspond to the connecting grooves one by one. The magnetic blocks 2 are magnetic, and the magnetic blocks 2 are attracted to the side of the mounting frame, thereby improving the connection stability between the mounting plate 1 and the mounting frame.

[0049] Compared to the prior art, in which the mounting plate and the mounting frame are fixed by screws, in the present application, the mounting frame is connected to the mounting plate 1 by magnetic attraction. When the display unit is damaged and needs to be repaired, the operator can apply an outward force to the mounting plate 1 from the front of the mounting plate 1 to disassemble the display unit, thereby improving the convenience of disassembly and assembly between the display unit and the mounting frame. Therefore, the mounting frame can be fitted to the wall, thereby saving space between the wall and the mounting frame.

[0050] Reference Figure 1 and Figure 3 In order to improve the connection stability between the mounting plate 1 and the mounting frame, a locking column 31 is provided on the back of the mounting bar 11. In the embodiment of the present application, the locking column 31 is a "T"-shaped column. A stabilizing column 32 is fixed to the back of the mounting bar 11. A stabilizing groove is provided at one end of the stabilizing column 32 away from the lamp bead 12. One end of the locking column 31 is inserted into the stabilizing groove. The locking column 31 and the stabilizing column 32 are rotatably connected. The other end of the locking column 31 is inserted into the locking groove of the mounting frame. When the long side direction of the locking column 31 is perpendicular to the long side direction of the mounting bar 11, it is in a locked state. At this time, the connection between the mounting plate 1 and the mounting frame is more stable, thereby reducing the situation where the mounting plate 1 falls off the side wall of the mounting frame.

[0051] The number of locking columns 31 depends on the specific situation. In the embodiment of the present application, the number of locking columns 31 is four. The four locking columns 31 are distributed on the back of the mounting strip 11 at the upper and lower ends, two locking columns 31 are distributed on the back of the mounting strip 11 at the upper end, and the other two locking columns 31 are distributed on the back of the mounting strip 11 at the lower end.

[0052] When a display unit is damaged and needs to be disassembled for repair or replacement, the operator first inserts the disassembly tool into the circulation groove 14. The disassembly tool is a column with a diameter smaller than the width of the circulation groove 14, so that the disassembly tool can pass through the circulation groove 14. The circulation groove 14 into which the disassembly tool is inserted is covered by the locking column 31. The disassembly tool is then moved along the circulation groove 14. When the disassembly tool contacts the locking column 31, force is continued to be applied to the disassembly tool to rotate the locking column 31 until the long side of the locking column 31 is parallel to the long side of the mounting strip 11. At this time, the locking column 31 is in an open state. The operator applies an outward force to the mounting plate 1 to remove the locking column 31 from the locking groove of the mounting frame, thereby disassembling the display unit.

[0053] Reference Figure 3An empty slot 33 is provided on the side of the locking column 31 away from the mounting strip 11. The empty slot 33 can reduce the weight of the locking column 31, so that when the disassembly tool rotates the locking column 31, the force applied by the operator is smaller, thereby facilitating better rotation of the locking column 31. At the same time, the material used for the locking column 31 can be saved, reducing costs and resources.

[0054] The surfaces of the multiple mounting strips 11 close to the lamp beads 12 are respectively covered with a waterproof layer. Under the action of the waterproof layer, the waterproof layer can reduce the entry of rainwater, moisture or water into the interior of the display screen, protect the circuit board and electronic components from moisture erosion, thereby reducing short circuits, corrosion or other damage caused by moisture.

[0055] A power plug 41 is fixed to the bottom of the back side of the mounting plate 1, and a slot 42 is provided inside the power plug 41. A power plug is inserted into the slot 42 to provide power for the display unit. A waterproof groove is provided on the back side of the mounting plate 1, and the waterproof groove is located outside the power plug 41. A sealing ring 43 is provided on the outer wall of the power plug 41, and the sealing ring 43 is inserted into the waterproof groove. When the power plug is inserted into the slot 42 for charging, one side of the power plug is pressed against the outer wall of the sealing ring 43. The sealing ring 43 has elasticity. When the sealing ring 43 is pressed against the power plug, the sealing ring 43 can fill the joint or gap between the power plug and the power plug 41 to form a physical barrier, thereby reducing moisture from entering the device through these openings, thereby achieving a waterproof effect.

[0056] A connecting seat is fixed by screws in the middle of the back side of the mounting bar 11, and a handle 5 is rotatably connected to the side wall of the connecting seat. The side wall of the handle 5 is in contact with one side of the mounting bar 11. When the operator needs to lift the display unit, the handle 5 is rotated to make the side wall of the handle 5 away from the mounting bar 11. Then the operator lifts the handle 5, thereby lifting the entire display unit. With the help of the handle 5, the convenience of taking the display unit is improved.

[0057] Reference Figure 1 When the mounting plate 1 is a rectangular plate, multiple mounting plates 1 are assembled to form a display screen in the same plane. When two vertical display screens need to be formed, one side of the mounting plate 1 is a 45° inclined surface, and the inclination direction is from the front of the mounting plate 1 to the back of the mounting plate 1. The two cut display units are assembled, and the two display units are abutted with each other at a 45° inclined surface, so that after the two display units are assembled, the screens of the two display units are perpendicular. Similarly, depending on the specific scenario, when a certain angle needs to be formed between the two display screens, one side of the mounting plate 1 is an inclined surface of the corresponding angle, so that after the two inclined surfaces are assembled, two display screens of the corresponding angle can be formed.

[0058] The embodiment of the present application discloses the processing steps of processing one side of the mounting plate 1 into an inclined surface:

[0059] S1: Processing of rectangular mounting plate 1: firstly place the raw material plate in a bending machine for bending, or use a mold to punch the raw material plate, so that the raw material plate forms a rectangular mounting plate 1. The mounting plate 1 is uniformly produced as a rectangular plate during production.

[0060] S2: Inclined surface processing: When it is necessary to use the mounting plate 1 with an inclined surface, first place the rectangular mounting plate 1 on the top surface of the cutting work platform, align the surface to be cut with the output end of the cutting device, then set the angle of the inclined surface to be cut, and finally start the cutting device. The cutting device cuts one side of the rectangular mounting plate 1 and cuts one side of the mounting plate 1 into an inclined surface of the corresponding angle.

[0061] Compared with the prior art, when a mounting plate 1 with a 45° inclined surface is required, two sets of molds are required to process the mounting plate 1. One side of the mounting plate 1 is processed into a 45° inclined surface by using two sets of molds, which makes it more troublesome to process one side of the mounting plate 1 into a 45° inclined surface, and the processing takes a long time. The number of mounting plates 1 that require inclined surfaces is small, and the required number is the number of mounting plates 1 in two vertical columns at the junction of two display screens. Therefore, the mounting plates 1 that need to be produced in large quantities are rectangular mounting plates 1. Therefore, in the embodiment of the present application, rectangular mounting plates 1 are first produced uniformly. When a mounting plate 1 with an inclined surface is required, the uniformly produced rectangular mounting plates 1 are cut by a cutting device, so that it is more convenient to process one side of the mounting plate 1 into a 45° inclined surface, thereby improving the production efficiency of processing one side of the mounting plate 1 into a 45° inclined surface.

[0062] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
