Description

Technical Field

[0001] The present invention relates to the technical field of LED splicing screens, and more specifically to an LED splicing screen based on a mortise and tenon structure. Background Art

[0002] The splicing screen forms a large screen display without borders or with extremely narrow borders by splicing multiple screens together, so as to display images of larger size and higher resolution. Each screen has its own controller, which transmits the image signal to the corresponding screen through the controller, so as to realize the splicing display of the image. The resolution of the splicing screen depends on the number of spliced ​​screens and the resolution of each screen.

[0003] In order to better ensure the display effect, a complete spliced ​​screen is often formed by splicing multiple spliced ​​screen monomers, and the area after splicing is generally large, which is prone to inconvenience in transportation. Therefore, the conventional way is to transport the spliced ​​screen to a designated location and then assemble it one by one.

[0004] At present, the common splicing method of splicing screens is generally to use screws and bolts for splicing. During long-term use, the screws and bolts will rust. At the same time, when the splicing screen is used outdoors, the splicing screen often needs to be moved many times, and then the screws and bolts need to be repeatedly disassembled and assembled. In this process, it is easy to cause wear of the threads on the screws, bolts and corresponding screw holes. If things go on like this for a long time, the screws and bolts will become loose after splicing, which will eventually affect the splicing effect and the display effect of the splicing screen.

[0005] Therefore, in view of this, the existing structure is studied and improved, and an LED splicing screen based on the mortise and tenon structure is provided, in order to achieve a more practical purpose. Summary of the invention

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0053] Embodiment 1:

[0054] See also Figure 1 - Figure 8 An LED splicing screen based on a mortise and tenon structure includes a plurality of single LED display screens 1, a stable bracket 2 is fixedly installed on the back of each single LED display screen 1, a plurality of single LED display screens 1 are combined horizontally and vertically to form an LED splicing screen structure, and a protective frame 3 is wrapped on the side of the LED splicing screen structure.

[0055] A plurality of single LED display screens 1 are arranged and combined horizontally and vertically, and then a mortise and tenon structure is formed between adjacent stable brackets 2 to form an LED splicing screen. Then, the outer edge of the LED splicing screen is wrapped with a protective frame 3 to form a complete LED large screen.

[0056] The stable bracket 2 is a #-shaped structure, and the eight end positions of the stable bracket 2 are fixedly provided with connectors 4, and any two adjacent connectors 4 are centrally symmetrically arranged, and a transverse locking connector 5 is arranged between two transversely adjacent stable brackets 2, and a mortise and tenon structure is formed between the end of the transverse locking connector 5 and the two adjacent connectors 4.

[0057] Since the structure of each connector 4 is the same, the difficulty of splicing can be reduced when splicing is performed based on the mortise and tenon structure, wherein one type of mortise and tenon structure completes the mortise and tenon connection of the horizontal stable bracket 2, that is, completes the horizontal splicing of the single LED display screen 1.

[0058] A longitudinal locking connector 6 is provided between two longitudinally adjacent stabilizing brackets 2, and a second type of mortise and tenon structure is formed between the end of the longitudinal locking connector 6 and two adjacent connectors 4. The first type of mortise and tenon structure and the second type of mortise and tenon structure have the same structure and are oriented perpendicular to each other in space.

[0059] The second type of mortise and tenon structure completes the mortise and tenon connection of the longitudinal stable bracket 2, that is, completes the longitudinal splicing of the single LED display screen 1

[0060] The connector 4 includes an end 401, which is fixed to the end of the stable bracket 2. The end 401 is provided with an insertion tenon 402, a docking strip groove 403, a shifting strip plate 404 and an insertion tenon groove 405 in sequence from top to bottom at the side position of the end 401 away from the stable bracket 2. The insertion tenon 402 is fixed to the top of the side of the end 401, the docking strip groove 403 is opened in the middle and upper part of the side of the end 401, the shifting strip plate 404 is fixed to the middle and lower part of the side of the end 401, and the insertion tenon groove 405 is opened at the bottom of the side of the end 401. Two first docking tenon grooves 406 are opened on the side of the end 401, and a second docking tenon groove 407 is opened on the side of the insertion tenon 402;

[0061] The transverse locking connector 5 and the longitudinal locking connector 6 form a plug-in structure with the corresponding first docking groove 406 and second docking groove 407 respectively.

[0062] After the transverse locking connector 5 is inserted into the corresponding first butt mortise and tenon grooves 406 and second butt mortise and tenon grooves 407, a relatively flat plane can be formed. At this time, not only the locking of the mortise and tenon structure is completed, but also the aesthetics of the mortise and tenon structure after completion is ensured.

[0063] See also Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8 Specifically, the transverse locking connector 5 and the longitudinal locking connector 6 have the same structure, and the two are vertically arranged in space.

[0064] During splicing, since the transverse locking connector 5 and the longitudinal locking connector 6 have the same structure, they can be used arbitrarily, which reduces the time required to identify the transverse locking connector 5 and the longitudinal locking connector 6 when splicing the LED display screen, and improves the efficiency of splicing.

[0065] See also Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 Specifically, the transverse locking connector 5 includes a connecting workpiece 501, two docking workpieces 502 and two stainless steel latch workpieces 503. The two ends of the connecting workpiece 501 are respectively fixed to one docking workpiece 502, and the stainless steel latch workpiece 503 is inserted into the interior of the adjacent docking workpiece 502 to form a locking position.

[0066] The docking workpiece 502 of the horizontal locking connector 5 performs another riveting on the two connectors that have been riveted. The connecting workpiece 501 can connect the two docking workpieces 502 together and use them synchronously, reducing the number of connection structures required when splicing the LED screen and improving the connection efficiency. The stainless steel plug lock workpiece 503 can lock between the docking workpiece 502 and the connector 4, ultimately ensuring the stable riveting of the two single LED displays 1 at the horizontally adjacent positions.

[0067] The structure and principle of the longitudinal locking connector 6 are the same as those of the horizontal locking connector 5, which can ensure the stable riveting of the two single LED displays 1 at the longitudinally adjacent positions.

[0068] Specifically, two arc-shaped pieces 5011 are fixedly arranged on the side of the connecting workpiece 501, and through holes 5012 are formed in the arc-shaped pieces 5011.

[0069] When separating the horizontal locking connector 5, to prevent the docking between the horizontal locking connector 5 and the connector 4 from being too tight, tools such as a crowbar can be used to pass through the through hole 5012, and then the horizontal locking connector 5 can be pried to ensure the smooth separation process.

[0070] The separation effect between the longitudinal locking connector 6 and the connector 4 is the same.

[0071] Specifically, the docking workpiece 502 is of a C-shaped structure, and four locking tenons 5021 are fixedly arranged on the inner side surface of the C-shaped structure. The four locking tenons 5021 respectively form mortise-and-tenon joints with the corresponding first docking mortises 406 and second docking mortises 407.

[0072] After a type of mortise-and-tenon structure is formed, the insertion tenon 402 is inserted into the corresponding insertion mortise 405, and the blocking strip plate 404 is inserted into the corresponding docking strip groove 403. At this time, the two connectors 4 can only be separated horizontally. Then, by inserting the four locking tenons 5021 into the corresponding first docking mortises 406 and second docking mortises 407 respectively, the positions of the two connectors 4 can be locked to prevent them from separating, and a relatively stable mortise-and-tenon structure is formed.

[0073] Specifically, an insertion hole 4011 is formed in the upper end surface of the end 401, and the insertion hole 4011 penetrates the upper and lower end surfaces of the end 401;

[0074] A countersunk head groove 5022 is formed in the upper end surface of the docking workpiece 502, and a through hole 5023 is formed in the inner bottom of the countersunk head groove 5022. The through hole 5023 penetrates the upper and lower end surfaces of the docking workpiece 502. The stainless steel plug lock workpiece 503 sequentially passes through the through hole 5023 and the insertion hole 4011;

[0075] Magnetic metal sheets are attached to the inner wall of the through hole 5023.

[0076] There is still a risk that the end head 401 and the docking workpiece 502 may be separated after docking. The locking can be completed by passing the stainless steel latch workpiece 503 through the penetration hole 5023 and the insertion hole 4011. Then, the magnetism of the stainless steel latch workpiece 503 is used by the magnetic metal sheet to ensure the stability of the locking of the end head 401 and the docking workpiece 502. At this time, the locking position of the stainless steel latch workpiece 503 is inside the countersunk groove 5022.

[0077] Through the mortise and tenon connection between the above structures, the surface of the first type mortise and tenon structure or the second type mortise and tenon structure is made flat, thereby enhancing the aesthetics of the LED splicing screen with the mortise and tenon structure.

[0078] See also Figure 3 , Figure 7 Specifically, the width of the docking strip groove 403 is equal to the width of the shift strip plate 404;

[0079] The depth of the docking strip groove 403 is equal to the length of the shifting strip plate 404 .

[0080] In this way, a more precise docking can be achieved between the docking strip groove 403 and the shift strip plate 404. At the same time, since the docking strip groove 403 is located below the shift strip plate 404, after the two are docked, the two docking joints 4 can only be separated horizontally.

[0081] Embodiment 2:

[0082] Based on the above embodiment 1, further description is given.

[0083] See also Figure 1 Specifically, the inner edge length and width of the protection frame 3 are respectively integer multiples of the outer side length and width of the single LED display screen 1;

[0084] According to the required display screen size, select the corresponding number of single LED display screens 1 for splicing to form an LED splicing screen structure, and then select the corresponding size of the protection frame 3 to perform frame protection on the LED splicing screen structure, so that the spliced ​​LED splicing screen structure meets the actual use requirements.

[0085] The thickness of the protection frame 3 is equal to the thickness of the single LED display screen 1 .

[0086] Ensure that the protective frame 3 has enough protection space for the LED splicing screen.

[0087] See also Figure 2 , Figure 3 Specifically, four docking bolt buckles 201 are fixedly installed on the stabilizing bracket 2, and the four docking bolt buckles 201 are distributed at the four corner points of the rectangle.

[0088] The docking bolt buckle 201 is located at the position of the horizontal strip of the stabilizing bracket 2. When the LED splicing screen is spliced, it can be conveniently fixed to the bracket by bolts to complete the vertical support of the LED splicing screen.

[0089] See also Figure 2 Specifically, a protective cap 408 is sleeved on each of the connectors 4 near the protective frame 3 , and an extension plate 4081 is fixedly disposed on the side of the protective cap 408 .

[0090] The protective cap 408 is used to protect the connector 4 that does not need to be riveted. The extension plate 4081 is used to facilitate the separation of the protective cap 408 from the connector 4 when the extension plate 4081 is pushed.

[0091] Working principle:

[0092] The LED splicing screen is formed by splicing and assembling a number of single LED display screens 1, and then the protection frame 3 is used to protect the frame of the LED splicing screen.

[0093] During splicing, a first-class mortise and tenon structure is used to splice two laterally adjacent single LED display screens 1, and a second-class mortise and tenon structure is used to splice two longitudinally adjacent single LED display screens 1. The splicing process of the first-class mortise and tenon structure is as follows:

[0094] The two stable brackets 2 are close to each other, and the corresponding two connectors 4 are close to each other synchronously. At this time, the insertion tenon 402 is inserted into the corresponding insertion tenon groove 405, and the shifting strip plate 404 is inserted into the corresponding docking strip groove 403, until the two connectors 4 are tightly fitted, and then, the four locking tenons 5021 on the docking workpiece 502 of the transverse locking connector 5 are passed through the corresponding first docking tenon groove 406 and the second docking tenon groove 407, and then, the stainless steel latch workpiece 503 is passed through the penetration hole 5023 and the insertion hole 4011, and at the same time, the magnetic metal sheet is used to magnetize the stainless steel latch workpiece 503 to complete the locking, so that the splicing process of a type of mortise and tenon structure can be completed.

[0095] The splicing process of the second type of mortise and tenon structure is the same as that of the first type.

[0096] When the splicing is completed, the LED splicing screen and the bracket can be fixed by the docking bolt buckle 201 and the bolt, completing the splicing and assembly process of the entire LED splicing screen.

[0097] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
