A frame is used to hold the multiple screens, and then the small LED screens are connected. A host computer controls the content displayed on the screens, so that the large LED screen can display the desired content.

[0004] Currently, LED screens are generally installed using screws during assembly. In the basic operation stage, screw fixing requires multiple steps such as precise alignment, tool matching, and step-by-step tightening. Each screw must be strictly aligned with the screw hole. Even a slight deviation will prevent it from being screwed in smoothly, requiring repeated adjustments. Different sizes of screws require corresponding screwdrivers, wrenches, and other tools. Frequent tool changes will significantly disrupt the continuity of the operation. Furthermore, screen fixing often requires dozens of screws. This repetitive operation accumulates into a huge time cost and significantly slows down the overall assembly progress. Utility Model Content

[0008] Furthermore, the insertion rods at the front ends of the unidirectional and bidirectional insertion brackets are connected to their corresponding guide slots by movable guides.

[0009] Furthermore, the dimensions of the slot are matched with the dimensions of the insert rods at the front end of the unidirectional and bidirectional inserts.

[0010] Furthermore, the locking assembly includes a gear, which is mounted on a section of the transmission rod. A fixing block is fixed on one side of the front end of the preset concave area, and a return spring is installed on both sides of one side of the fixing block.

[0014] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: When a worker needs to assemble a screen in the mounting slot at the front end of the assembly frame, taking one assembly operation as an example, the worker can first use the positioning block and positioning slot to align and install the screen into the mounting slot. Then, by pulling the connecting plate with one hand, the two return springs are stretched. In this state, the guide rod and the toothed block at the end of the connecting plate will cooperate with the guide groove to disengage from the corresponding tooth groove of the gear fixed in a section of the transmission rod. Subsequently, the worker manually rotates the transmission rod to rotate the first bevel gear. At this time, the bevel gear will mesh and drive the second bevel gear and the positive and negative lead screw in the middle to rotate synchronously. As a result, the two opposing second lead screw sleeves that interact with the positive and negative lead screws will carry the bidirectional insertion bracket and cooperate with the guide groove to align and insert into the slot. The system forms a double-sided fixation. Because the periphery of the opposite sections of the positive and negative lead screws is fixed with a third bevel gear, and the two third bevel gears are meshed with fourth bevel gears on both sides, during the movement of the positive and negative lead screws, the fourth bevel gears driven by the transmission will rotate their respective fixed transmission lead screws. As a result, the first lead screw sleeve that interacts with each transmission lead screw will carry the one-way insert bracket and guide the guide groove to be aligned and inserted into another slot to form another double-sided fixation. Through this operation, the multi-sided linkage stable assembly of the screen can be achieved. After the assembly is completed, the personnel slowly release the connecting plate. At this time, under the reset action of the reset spring, the tooth block at the end of the guide rod will be aligned and locked into the corresponding tooth groove of the gear, thereby indirectly achieving the stable positioning of the entire assembly structure.

[0015] After the entire assembly of this utility model is completed, personnel can use guide blocks to guide and push the shielding frame so that the shielding frame is close to one end of the fixed shell. Since there is a magnetic block at the joint between the two, a stable connection can be achieved, thereby shielding the exposed parts of the assembly mechanism and improving the overall aesthetics.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This specific embodiment is a screen that is easy to assemble, and its structural diagram is shown below. Figures 1 to 4As shown, the assembly includes an assembly frame 1, with mounting slots 2 at its front end. Screens 3 are mounted in the middle of multiple mounting slots 2. An assembly mechanism 4 is connected to the contact portion of the mounting slots 2 and the screens 3. A blocking mechanism 5 is provided at the lower front end of the screens 3. The assembly mechanism 4 includes a positioning block 41 and a transmission rod 441. The positioning block 41 has two sides in the middle of the mounting slots 2. Positioning slots 42 are opened on both sides of the inner edge of the screens 3. A preset recessed area 43 is provided at the lower front end of the screens 3. An assembly component 44 is provided inside the rear end of the screens 3. The assembly component 44 includes a transmission rod 441, which is installed in the middle of the preset recessed area 43. A first bevel gear 442 is connected to the end of the transmission rod 441. A second bevel gear 443 is engaged with the screen 3. A forward and reverse lead screw 444 is fixedly mounted in the middle of the second bevel gear 443. A third bevel gear 445 is fixedly mounted on the periphery of both sides of the middle section of the forward and reverse lead screw 444. A fourth bevel gear 446 is engaged with the two third bevel gears 445 on both sides. A transmission lead screw 447 is fixedly mounted in the middle of the two pairs of fourth bevel gears 446. A first lead screw sleeve 448 is screwed onto one side of the transmission lead screw 447. A one-way insert 449 is fixedly mounted around the periphery of the first lead screw sleeve 448. A second lead screw sleeve 4410 is screwed onto both sides of the middle section of the forward and reverse lead screw 444. A two-way insert 4411 is fixedly mounted around the periphery of the second lead screw sleeve 4410. A guide groove 4412, a one-way insert 449, and a two-way insert 4411 are provided around the periphery of the screen 3. The insertion rods at the front end of the frame 4411 are connected to the corresponding guide grooves 4412 by movable guides. The inner periphery of the mounting groove 2 is provided with slots 4413. The opening size of the slots 4413 matches the size of the insertion rods at the front end of the unidirectional insertion frame 449 and the bidirectional insertion frame 4411. A locking component 45 is provided on one side of the front end of the preset concave area 43. The locking component 45 includes a gear 451, and the gear 451 is installed on a section of the periphery of the transmission rod 441. A fixing block 452 is fixed on one side of the front end of the preset concave area 43. A return spring 453 is installed on both sides of one side of the fixing block 452. The end of the return spring 453 is connected to a connecting plate 454. A guide rod 455 is provided in the middle of the inner end of the connecting plate 454. The middle of the fixing block 452 is provided with a guide rod 455. There is a guide groove 456, and a toothed block 457 is fixedly provided at the end of the guide rod 455. The guide rod 455 and the guide groove 456 are connected by a guide assembly. The size of the toothed block 457 at the end of the guide rod 455 matches the size of the toothed grooves around the gear 451. When the operator needs to assemble the screen 3 in the fitting slot 2 at the front end of the assembly frame 1, taking one assembly operation as an example, the operator can use the positioning block 41 and the positioning groove 42 to pre-align and snap the screen 3 into the fitting slot 2. Then, the operator can pull the connecting plate 454 with one hand to stretch the two return springs 453. In this state, the guide rod 455 and the toothed block 457 at the end of the connecting plate 454 will cooperate with the guide groove 456 to guide and disengage from the corresponding toothed groove of the gear 451 fixed in the transmission rod 441.Subsequently, the operator manually rotates the transmission rod 441 to rotate the first bevel gear 442. At this moment, the bevel gear meshes and drives the second bevel gear 443 and the central positive and negative lead screw 444 to rotate synchronously. As a result, the two opposing second lead screw sleeves 4410 that interact with the positive and negative lead screw 444 will guide the bidirectional insert bracket 4411 to cooperate with the guide groove 4412 to be aligned and inserted into the slot 4413 to form a double-sided fixation. Since the periphery of the opposing sections of the positive and negative lead screw 444 is fixed with a third bevel gear 445, and the two third bevel gears 445 are meshed with a fourth bevel gear 446 on both sides, during the movement of the positive and negative lead screw 444, the transmission rod 442 rotates synchronously. The moving fourth bevel gear 446 rotates its fixed transmission screw 447, causing the first screw sleeve 448, which interacts with each transmission screw 447, to guide the unidirectional insert 449 into the guide groove 4412 and insert it into another slot 4413, forming another double-sided fixation. This operation achieves stable, multi-sided linkage assembly of the screen 3. After assembly, the connecting plate 454 is slowly released. At this moment, under the reset action of the return spring 453, the toothed block 457 at the end of the guide rod 455 will align and engage with the corresponding toothed groove of the gear 451, thereby indirectly achieving stable positioning of the entire assembly structure.

[0021] The shielding mechanism 5 includes a fixed shell 51, which is fixed to one side of the front end of the preset concave area 43. A guide block 52 is fixed to the other side of the front end of the preset concave area 43, and a shielding frame 53 is slidably mounted above the guide block 52. Magnetic blocks 54 are provided around the opposite ends of the fixed shell 51 and the shielding frame 53. The shielding frame 53 is magnetically fixed to the fixed shell 51 by the magnetic blocks 54. After the assembly is completed, the personnel can use the guide block 52 to guide and push the shielding frame 53 so that the shielding frame 53 is close to one end of the fixed shell 51. Since there are magnetic blocks 54 at the joint of the two, a stable connection can be achieved, thereby shielding the partially exposed part of the assembly mechanism 4 and improving the overall aesthetics.

[0022] Working principle: When the operator needs to assemble the screen 3 in the mounting slot 2 at the front end of the assembly frame 1, taking one assembly operation as an example, the operator can pre-align and snap the screen 3 into the mounting slot 2 using the positioning block 41 and the positioning slot 42. Then, the operator can pull the connecting plate 454 with one hand to stretch the two return springs 453. In this state, the guide rod 455 set at the inner end of the connecting plate 454 and the toothed block 457 at its end will cooperate with the guide slot 456 to guide and disengage the corresponding tooth of the gear 451 fixed in a section of the transmission rod 441. The groove is then manually rotated by the operator to make the first bevel gear 442 rotate. At this time, the bevel gear will mesh and drive the second bevel gear 443 and the positive and negative lead screw 444 in the middle to rotate synchronously. As a result, the two opposing second lead screw sleeves 4410 that interact with the positive and negative lead screw 444 will carry the bidirectional insert 4411 to cooperate with the guide groove 4412 to guide and align into the slot 4413 to form a double-sided fixation. Since the periphery of the opposing section of the positive and negative lead screw 444 is fixed with a third bevel gear 445, and the two third bevel gears are also fixed in this way, the groove is also fixed in this way. The gear 445 has a fourth bevel gear 446 meshing on both sides. Therefore, during the movement of the forward and reverse lead screws 444, the driven fourth bevel gears 446 will rotate their respective fixed transmission lead screws 447. Consequently, the first lead screw sleeve 448, which interacts with each transmission lead screw 447, will guide the one-way insert bracket 449, along with the guide groove 4412, into another slot 4413 to form another double-sided fixation. Through this operation, a multi-sided, linked, and stable assembly of the screen 3 can be achieved. After assembly, personnel slowly... When the connecting plate 454 is released, under the reset action of the return spring 453, the toothed block 457 at the end of the guide rod 455 will be aligned and engaged in the corresponding tooth groove of the gear 451, thereby indirectly achieving stable positioning of the entire assembly structure. After the assembly is completed, the personnel can use the guide block 52 to guide and push the shielding frame 53, so that the shielding frame 53 is close to one end of the fixed shell 51. Since there is a magnetic block 54 at the joint of the two, a stable connection can be achieved, thereby shielding the partially exposed part of the assembly mechanism 4 and improving the overall aesthetics.

[0023] All technical features in this embodiment can be freely combined according to actual needs.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing 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.
