Description

Technical Field

[0001] This invention relates to the field of LED display technology, and in particular to an LED display with adjustable splicing angle. Background Technology

[0002] LED displays are high-tech display devices that have been widely used in recent years. They are characterized by high screen brightness, high definition, stable quality, long life, flexible and versatile display functions, and arbitrary combination of screen area. They are very suitable for playing and advertising programs such as text, graphics, and high-definition video. In the field of indoor and outdoor displays, they have an irreplaceable position compared to other display devices.

[0003] In the prior art, Chinese patent document (patent number: CN201920297588.X, patent name: LED display cabinet and LED display) discloses that "the cabinet frame includes: a mounting part, including a display surface and a back surface arranged opposite to each other, the LED display module being fixed on the display surface; a first splicing member, disposed on the back edge of the mounting part, including a first splicing plate, the first splicing plate being provided with a groove and a through hole; and a second splicing member, disposed on the back edge of the mounting part, and different from the first splicing member of the LED display cabinet." The first and second splicing components are detachably fixed. The second splicing component includes a second splicing plate, a positioning post, and a fastener. The second splicing plate has an outer end face relatively close to the edge of the mounting portion. The positioning post is disposed on the outer end face of the second splicing plate and extends outward. The second splicing plate is provided with a through hole, through which the fastener passes. When the first and second splicing components are fixed, the positioning post is at least partially received in the groove, and the fastener is at least partially received in the through hole and fixedly connected to the first splicing plate. Based on the description and drawings in the patent document, in the above solution, two adjacent LED displays are fixed to each other by a first splicing component and a second splicing component. However, the positions of the first splicing component and the second splicing component are fixed. Although this effectively ensures the flatness of the spliced ​​two LED displays, it does not allow for free adjustment of the curvature of the screen surface formed between the two LED displays, and thus cannot meet individual splicing requirements. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides an LED display screen with adjustable splicing angle, which can overcome the defects of the prior art mentioned in the background art.

[0009] Furthermore, the frame has corner brackets at its four corners, a power supply mounting slot in the middle of the frame, a power supply housing in the power supply mounting slot, cover plates on both sides of the power supply housing, a connection position in the middle of the cover plates, and a locking groove in the connection position.

[0010] Furthermore, the power supply housing includes an outer shell, a power supply is disposed inside the outer shell, an adapter plate is disposed below the power supply, a data card is disposed in the middle of the adapter plate, and transfer plates are disposed on both sides of the adapter plate, with the transfer plates disposed below the cover plate.

[0011] Furthermore, the locking shell is provided with connecting holes at both ends, and the connecting holes are provided with first glass ball screws. The locking rod is provided with first recesses and second recesses at both ends, and the first recesses and second recesses are used to cooperate with the ends of the first glass ball screws. A positioning rod is provided on one side of the locking shell, and a guide groove is provided on the other side of the locking shell. The locking rod is provided with a sliding rod, and the sliding rod is slidably connected to the guide groove.

[0012] Furthermore, the power supply mounting slot has a first mounting position at one end and a second mounting position at the other end. The first mounting position has a first fixing hole matching the positioning rod at its upper end, a first insertion groove below the first fixing hole, and an insertion hole inside the first insertion groove. The screw is inserted into the insertion hole. The second mounting position has a second fixing hole matching the positioning rod at its upper end, a second insertion groove matching the connector below the second fixing hole, a fixing mounting groove on the side of the second fixing hole, a first through hole inside the fixing mounting groove, and a second through hole at the bottom of the second insertion groove. The first through hole and the second through hole correspond to each other. A locking element is installed inside the second through hole.

Implementation

[0018] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0019] like Figures 1 to 17As shown, an LED display screen with adjustable splicing angle includes a frame 1. Two third mounting positions 104 are provided on the left side of the frame 1, and fixing components 4 are mounted on the third mounting positions 104. Two angle adjustment components 5 are provided on the right side of the frame 1 to work with the fixing components 4. The fixing components 4 include a first fixing base 401 and a fixing rod 407. First rotating columns 402 are provided on both sides of the first fixing base 401. Handles 403 are rotatably connected to the first rotating columns 402. Limiting components 405 are provided on the handles 403. Connecting columns 406 are provided below the limiting components 405. The two ends of the fixing rod 407 are connected to the connecting columns 406. 6. The angle adjustment component 5 includes an adjustment slider 501, a second fixing seat 502 is provided inside the adjustment slider 501, a slot 5014 that matches the fixing rod 407 is provided in the adjustment slider 501, and a sliding groove 5011 is provided in the adjustment slider 501. The second fixing seat 502 is provided with a sliding block 5021. When two adjacent frames are spliced, the adjustment slider 501 on one frame is in contact with the third mounting position 104 of the adjacent frame, while the fixing rod 407 of the adjacent frame is engaged in the slot 5014 of the one frame and is slidably connected in the sliding groove 5011 by the sliding block 5021, thereby adjusting the curvature of the screen surface formed between the two frames.

[0020] Specifically, such as Figure 11 As shown, a third rotating column 503 is provided above the second fixed base 502, and a push plate 504 is rotatably connected to the third rotating column 503; an angle indicator 5012 is provided above the slide groove 5011, as shown. Figure 12 As shown, the angle adjustment component 5 is in a locked state at this time. When the angle needs to be adjusted, simply lift the button 504 upwards so that the bottom end of the button 504 is away from the upper end face of the second fixed seat 502 and disengages from the locking state. Then, move the adjustment slider 501 so that the sliding block 5021 slides in the slide groove 5011. Then, according to the angle mark 5012, make the sliding block 5021 stop at the corresponding angle position to adjust the angle of the adjustment slider 501. Then, press the button 504 downwards so that the lower end face of the button 504 gradually fits into the upper end face of the second fixed seat 502. Since the lower end face of the button 504 and the upper end face of the second fixed seat 502 are both inclined surfaces, the friction generated when the two fit together will lock the adjustment slider 501. This angle adjustment design allows the two frames 1 to be connected at the same time and form an angle, effectively meeting individual angle requirements.

[0021] like Figure 15As shown, several snap-fit ​​recesses 4061 are distributed at both ends of the connecting post 406, and fixed positions 4031 are provided at both ends of the handle 403 below. The fixed positions 4031 are provided with second glass ball screws 404. The second glass ball screws 404 correspond to the snap-fit ​​recesses 4061. When the fixed rod 407 is moved, the second glass ball screws 404 will snap with the corresponding snap-fit ​​recesses 4061, which can effectively fix the fixed rod 407 and prevent the fixed rod 407 from shifting.

[0022] The limiting assembly 405 includes a second rotating column 4051, which is rotatably connected to the handle 403. The second rotating column 4051 is provided with a limiting element 4052 and a torsion spring 4053, which is located in the middle of the second rotating column 4051. One end of the torsion spring 4053 abuts against the limiting element 4052, and the other end abuts against the connecting column 406. The first fixed seat 401 is provided with a locking recess 4011. One end of the limiting element 4052 is provided with a button 4054, and the other end of the limiting element 4052 corresponds to the locking recess 4011. Figure 14 As shown, the limiting component 405 is in the locked state. Pressing the button 4054 causes the limiting member 4052 to rotate, causing the other end of the limiting member 4052 to lift up and separate from the locking recess 4011, thereby releasing the limiting component 405 from the locked state. Because the torsion spring 4053 is elastic, when the button 4054 is released, the torsion spring 4053 will cause the button 4054 to reset, thereby allowing the other end of the limiting member to return to the locking recess 4011, thus locking it.

[0023] like Figure 16 As shown, the third mounting position 104 has two positioning grooves 1041 on its side, and two first positioning holes 1042 are provided below the positioning grooves 1041. The first fixing seat 401 has two second positioning holes 4012 on its side. The first positioning holes 1042 and the second positioning holes 4012 correspond to each other. Screws are used to pass through the first positioning holes 1042 and the second positioning holes 4012 so that the side of the first fixing seat 401 fits and is fixed to the side of the third mounting position 104, which facilitates connection with the angle adjustment component 5 of another frame 1.

[0024] The adjusting slider 501 is equipped with two mounting posts 5013 that match the positioning groove 1041. When it is necessary to horizontally splice two frames 1, simply connect the angle adjusting component 5 of one frame 1 with the fixing component 4 of the other frame 1. Specifically, first align the mounting post 5013 of one frame 1 with the positioning groove 1041 of the other frame 1, and then move the fixing rod 407 of the other frame 1 to engage with the slot 5014 of one frame 1. This will fix the two frames 1 horizontally together. When it is necessary to horizontally disassemble the two frames 1, simply press the button 4054 of the other frame 1 to release the locking state of the limiting component 405, and then hold the handle 403 and lift it upwards. This will cause the fixing rod 407 to move forward, disengaging the fixing rod 407 from the slot 5014 of the other frame 1. Then, use the other hand to rotate the fixing rod 407 upwards to achieve disassembly.

[0025] A connecting component 2 is provided on the upper side of the frame 1, and a locking component 3 is provided on the lower side of the frame 1 to cooperate with the connecting component 2. The connecting component 2 includes a connector 201, which is connected to a screw 202. The connector 201 is provided with a mounting hole 2011 that matches the locking rod 302. The locking component 3 includes a locking housing 301 and a locking rod 302. The locking rod 302 is slidably connected in the locking housing 301. A handle 303 is connected to the upper end of the locking rod 302. The locking housing 301 is provided with connecting holes 3011 at both ends. A first glass ball screw 3012 is provided in the connecting holes 3011. A second glass ball screw 3012 is provided at both ends of the locking rod 302. The first recess 3021 and the second recess 3022 are used to engage with the end of the first glass ball screw 3012. When the locking rod 302 moves upward, the first glass ball screw 3012 will make a sound when it aligns with the second recess 3022, indicating to the user that the locking rod 302 has risen sufficiently and the connecting component 2 of the other frame 1 can be inserted into the second insertion slot 1022. When the locking rod 302 moves downward, the glass ball screw 3012 will make a sound when it aligns with the first recess 3021, indicating to the user that the locking rod 302 has fallen sufficiently and the next locking operation can be performed.

[0026] A positioning rod 3013 is provided on one side of the locking housing 301, and a guide groove 3014 is provided on the other side of the locking housing 301. The locking rod 302 is provided with a sliding rod 3023, which is slidably connected to the guide groove 3014. The sliding rod 3023 plays a guiding and limiting role. The locking rod 3022 can only move up and down when the sliding rod 3023 and the guide groove 3014 are on the same straight line.

[0027] A power supply mounting slot 103 is provided in the middle of the frame 1. A power supply housing 6 is provided in the power supply mounting slot 103. Cover plates 7 are provided on both sides of the power supply housing 6. A connection position 701 is provided in the middle of the cover plate 7. A locking groove 7011 is provided in the connection position 701. The locking groove 7011 is designed to cooperate with the wind resistance bracket to facilitate the fixing of the wind resistance bracket to the frame 1.

[0028] The power supply housing 6 includes an outer shell 601, inside which a power supply 602 is installed. Below the power supply 602, an adapter plate 603 is installed. In the middle of the adapter plate 603, a data card 605 is installed. The data card 605 serves as an information relay for easy control. On both sides of the adapter plate 603, there are transmission plates 604. The transmission plates 604 are located below the cover plate 7. The power of the power supply 602 is transmitted through the adapter plate 603 to the transmission plates 604 on both sides, and then transmitted by the transmission plates 604 to the corresponding modules 10 to achieve the power supply function.

[0029] One end of the power mounting slot 103 is provided with a first mounting position 101, and the other end of the power mounting slot 103 is provided with a second mounting position 102. The upper end of the first mounting position 101 is provided with a first fixing hole 1011 that matches the positioning rod 3013. The lower end of the first fixing hole 1011 is provided with a first insertion slot, and the first insertion slot is provided with an insertion hole 1012. The screw 202 is inserted into the insertion hole 1012, and the end of the screw 202 is provided with a nut. By tightening the nut, the connecting component 2 can be fixed on the first mounting position 101.

[0030] The upper end of the second mounting position 102 is provided with a second fixing hole 1021 that matches the positioning rod 3013. Below the second fixing hole 1021, a second insertion groove 1022 that matches the connector 201 is provided. The side of the second fixing hole 1021 is provided with a fixing mounting groove 1023. The fixing mounting groove 1023 is provided with a first through hole 1024. The bottom of the second insertion groove 1022 is provided with a second through hole. The first through hole 1024 corresponds to the second through hole. The second through hole is provided with a locking member 1025. The locking shell 301 is provided in the fixing mounting groove 1023. The end of the locking rod 302 passes through the first through hole 1024 and is connected to the locking member 1025. The positioning rod 3013 is inserted into the second fixing hole 1021. When the two frames 1 are spliced ​​together, the positioning rod 3013 will pass through the second fixing hole 1021 and the first fixing hole 1011 in sequence, thereby playing a fixed positioning role.

[0031] When two frames 1 need to be joined longitudinally, simply grasp the handle 303 and pull it upwards to move the locking rod 302 upwards. Then, insert the connector 201 of the other frame 1 into the second insertion slot 1022. Grasp the handle 303 again and press it downwards to move the locking rod 302 downwards. The locking rod 302 passes through the first through hole 1024 and the mounting hole 2011 in sequence to reach the locking member 1025. At this time, the slide rod 3023 is not in the guide groove 3014, so the handle 303 can be grasped to rotate the locking rod 302 90 degrees clockwise for locking operation (e.g., Figure 8 As shown, the bottom end of the locking rod 302 is irregularly elliptical, and the locking member 1025 is circular. When the locking rod 302 is just inserted into the locking member 1025, the locking rod 302 can still be raised. When the locking rod 302 rotates 90 degrees, the slide rod 3023 rotates 90 degrees accordingly, preventing the locking rod 302 from rising and limiting its position. The end of the locking rod 302 will also change its position within the locking member 1025 due to the rotation, causing the distance between the two sides of the locking rod 302 to be greater than that between the two sides of the locking member 1025. The long distance allows for the locking of the locking element 1025, thus achieving a locking effect. When it is necessary to disassemble the two frames 1 longitudinally, simply rotate the handle 303 to rotate the locking rod 302 counterclockwise by 90 degrees. This releases the locking rod 302 from the locking element 1025, while simultaneously aligning the slide rod 3023 and the guide groove 3014 in a straight line. Then, grasp the handle 303 and pull it upwards to move the locking rod 302 upwards. Finally, pull the connector 201 of the other frame 1 out of the second insertion groove 1022 to achieve disassembly.

[0032] like Figures 18 to 23 As shown, several modules 10 are arranged on the frame 1, and several LED beads 11 are arranged above the modules 10. The four corners of the frame 1 are provided with auxiliary corners 8, which include a lamp protector 801 and a mounting base 802. The mounting base 802 is provided with a snap-fit ​​position 8021. One end of the lamp protector 801 is snapped into the snap-fit ​​position 8021, and the other end of the lamp protector 801 is located at the corner of the frame 1. The lamp protector 801 is designed to protect the LED beads 11 on the module 10 and prevent the LED display screen from being damaged by collision.

[0033] A module handle 9 is provided at the bottom of the module 10. The module handle 9 includes a base 901 and a handle 902. The base 901 has limiting and fixing grooves 9011 at both ends, and the handle 902 has limiting and fixing posts 9021 at both ends. The limiting and fixing grooves 9011 and the limiting and fixing posts 9021 are engaged and connected, which not only fixes the base 901 and the handle 902 together, but also limits and fixes the handle 902. When transporting or installing the LED display, the handle 902 is rotated to the corresponding position. Through the cooperation of the limiting and fixing grooves 9011 and the limiting and fixing posts 9021, the position of the handle 902 is not easily changed due to the shaking of the module 10. It is convenient to use and does not easily cause positional deviation.

[0034] The limiting and fixing groove 9011 includes a fixing groove 90111, with first limiting grooves 90112 on the upper and lower sides of the fixing groove 90111, and second limiting grooves 90113 on the left and right sides of the fixing groove 90111. The limiting and fixing post 9021 includes a protrusion 90211, with first limiting posts 90212 on the upper and lower sides of the protrusion 90211, and second limiting posts 90213 on the left and right sides of the protrusion 90211. The fixing groove 90111 corresponds to the protrusion 90211, facilitating the fixing of the base 901 and the handle 902 together. The first limiting posts 90212 and the second limiting posts 90213 are both connected to the first limiting groove 90112. In conjunction with the second limiting groove 90113, rotating the handle 902 aligns the first limiting post 90212 with the first limiting groove 90112 and the second limiting post 90213 with the second limiting groove 90113. When this is done, the handle 902 is in a horizontal position, so that the end face of the base 901 and the end face of the fourth rotating post 9023 are on the same horizontal line, which is not only aesthetically pleasing but also convenient for transportation. When the second limiting post 90213 aligns with the first limiting groove 90112 and the first limiting post 90212 aligns with the second limiting groove 90113, the handle 902 is in an upright position, which is convenient for removal and also facilitates the installation of the LED display screen.

[0035] The handle 902 includes a hand lever 9022, with fourth rotating posts 9023 at both ends of the hand lever 9022. A limiting and fixing post 9021 is located on the side of the fourth rotating post 9023. A reset groove 9012 is located on the side of the limiting and fixing groove 9011. The fourth rotating post 9023 is rotatably connected to the reset groove 9012, which provides support. Figure 20 It can be seen that the reset groove 9012 is an arc position, which fits the shape of the fourth rotating column 9023, making it easy for the fourth rotating column 9023 to rotate.

[0036] Both the first limiting groove 90112 and the second limiting groove 90113 are arc-shaped. The arc-shaped design makes it easy to rotate the handle 902 and avoids the handle 902 being stuck and unable to rotate.

[0037] The base 901 has a step 9013 in the middle. The step 9013 design can effectively prevent the screw from protruding and causing unevenness on the end face of the base 901 after installation. The step 9013 has a third fixing hole 90131. There are two positioning posts 9014 at the bottom of the base 901. The module 10 has a first fixing member 12. The first fixing member 12 has second fixing members 13 on both sides. The first fixing member 12 corresponds to the third fixing hole 90131. The second fixing member 13 corresponds to the positioning post 9014. The screw is used to fix the module 10 to the first fixing member 12 through the third fixing hole 90131. The two positioning posts 9014 correspond to the second fixing posts 13 of the module 10, thereby fixing the module handle 9 to the module 10 so that it will not fall off.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
