Description

Technical Field

[0001] This utility model belongs to the field of LED display technology, and more specifically, it relates to a splicing LED display. Background Technology

[0002] LED displays are an indispensable and flexible tool for modern events, commercial displays, and information dissemination. Their modularity, rapid installation, and reusability perfectly address the needs of temporary, dynamic, and space-constrained applications. Some existing floor-standing LED displays can be spliced ​​together to achieve multi-screen combinations displaying the same image (such as ultra-long background videos) or to enable dynamic content flow.

[0003] Existing floor-standing LED displays typically involve simply attaching the screens together without a rigid connection structure. When subjected to collisions, equipment movement, or ground vibrations, the cabinets are prone to displacement, resulting in physical gaps between the screens, disrupting the overall image integrity and affecting multi-screen interactive playback. Therefore, this paper researches and improves upon the existing structure and its shortcomings to provide a splicing LED display with greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a splicing LED display screen, which is achieved by the following specific technical means:

[0005] A splicing LED display screen includes a base, on which the display screen body is fixedly mounted. The base has a cavity inside, and two sets of through holes are symmetrically arranged on the top side of one end of the cavity. A light rod is slidably connected to the inside of each of the two sets of through holes. A locking tongue is fixedly connected to the bottom end of the two sets of light rods. An opening is provided on one side of the cavity corresponding to the locking tongue, and a connecting seat is fixedly mounted on the other end of the base corresponding to the locking tongue.

[0006] Furthermore, the two sides of the connecting seat are slidably connected to the two sides of the inner wall of the cavity on another set of bases.

[0007] Furthermore, a spring is sleeved on the outer side of the light rod, and the upper and lower ends of the spring abut against the top side of the inner wall of the cavity and the top side of the locking tongue, respectively.

[0008] Furthermore, the top ends of both sets of optical rods have through holes and are fixedly connected to limit blocks.

[0009] Furthermore, a connecting plate is fixedly connected to the top of one side of the locking tongue, a guide rail is fixedly connected to the bottom side of the connecting plate, a slider is slidably connected to the outer side of the guide rail, and connecting rods are rotatably connected to both sides of the slider via shafts. A through groove is provided on one side of the cavity, a fixed shaft is fixedly connected to the inner side of the through groove, and the inner sides of the connecting rods are rotatably connected to the outer side of the fixed shaft.

[0010] Furthermore, one end of each of the two sets of connecting rods extends through a slot and is fixedly connected to a pedal.

[0011] Furthermore, self-locking casters are fixedly installed on the four corners of the bottom side of the base.

[0012] Furthermore, a cover plate is fixedly installed on the inner side of the opening.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model enables flexible movement of the locking tongue within the base through the cooperation of the light rod and the limiting block. The cooperation of the spring and the light rod enables pressure to be applied to the locking tongue. The cooperation of the locking tongue and the connecting seat enables rigid connection of multiple display screen bodies, preventing gaps from appearing between the multiple display screen bodies when subjected to personnel collisions, equipment movement, or ground vibration impacts, thus ensuring the stability of multi-screen linkage playback.

[0015] 2. This utility model, through the cooperation of the pedal and the fixed shaft, can realize the flexible rotation of the light rod around the fixed shaft. Through the cooperation of the light rod and the slider, it can realize the flexible movement of the connecting plate and the locking tongue. Thus, when it is necessary to make contact with the display screen body, the locking tongue can be easily driven away from the connecting seat, which increases the convenience of the product during use.

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a splicing LED display screen, including a base 1. The display screen body 2 is fixedly installed on the top side of the base 1. The inner side of the base 1 is provided with a cavity. Two sets of through holes are symmetrically provided on the top side of one end of the cavity. Light rods 4 are slidably connected to the inner side of both sets of through holes. Locking tongues 5 are fixedly connected to the bottom ends of the two sets of light rods 4. An opening is provided on one side of the cavity corresponding to the locking tongue 5. A connecting seat 3 is fixedly installed on the other end of the base 1 corresponding to the locking tongue 5.

[0028] The two sides of the connecting seat 3 are slidably connected to the inner walls of the cavity on another set of bases 1 to prevent the connecting seat 3 from shaking after it is connected to the inner side of the cavity.

[0029] Among them, a spring 6 is sleeved on the outer side of the light rod 4. The upper and lower ends of the spring 6 abut against the top side of the inner wall of the cavity and the top side of the locking tongue 5, respectively, to prevent the locking tongue 5 from disengaging from the connecting seat 3 when it is not subjected to external force.

[0030] The top ends of both sets of light rods 4 protrude through the through holes and are fixedly connected to limit blocks 7 to prevent the light rods 4 from falling out of the through holes.

[0031] A connecting plate 8 is fixedly connected to the top of one side of the locking tongue 5, and a guide rail 9 is fixedly connected to the bottom side of the connecting plate 8. A slider 10 is slidably connected to the outer side of the guide rail 9. A connecting rod 12 is rotatably connected to both sides of the slider 10 via a shaft. A through groove is provided on one side of the cavity, and a fixed shaft 11 is fixedly connected to the inner side of the through groove. The inner side of the connecting rod 12 is rotatably connected to the outer side of the fixed shaft 11. The connecting plate 8 and the locking tongue 5 can be flexibly moved by rotating the connecting rod 12.

[0032] One end of each of the two sets of connecting rods 12 passes through a through slot and is fixedly connected to a pedal 13, which can enable the connecting rods 12 to rotate flexibly by stepping on the pedal 13.

[0033] The base 1 is equipped with self-locking casters 14 fixedly installed on the four corners of its bottom side, which allows the base 1 to move flexibly.

[0034] A cover plate 15 is fixedly installed on the inner side of the opening to protect the spring 6.

[0035] The working principle of this embodiment is as follows: When it is necessary to connect two sets of display screen bodies 2, push the connecting seat 3 on one set of display screen bodies 2 into the opening of the other set of display screen bodies 2. The inclined surface on the connecting seat 3 presses against the inclined surface on the locking tongue 5, causing the locking tongue 5 to move upward. After the connecting seat 3 passes the locking tongue 5, the locking tongue 5 moves downward under the action of the spring 6. At this time, the straight surface on the connecting seat 3 abuts against the straight surface on the locking tongue 5, completing the connection. When it is necessary to disconnect, step on the pedal 13 to drive the connecting rod 12 to rotate. The connecting rod 12 drives the connecting plate 8 and the locking tongue 5 to move upward through the slider 10 and the guide rail 9. After the locking tongue 5 leaves the connecting seat 3, pull out one set of display screen bodies 2 to complete the disassembly and assembly of the two sets of display screen bodies 2.
