Description

Technical Field

[0001] This utility model relates to the field of LED display cabinet splicing technology, specifically to an LED display cabinet arc splicing device. Background Technology

[0002] As is well known, LED displays are usually made up of multiple cabinets spliced ​​together, and the display panel is then fixed to the surface of the cabinet. Existing LED display cabinets have good heat dissipation performance, effectively protect the module circuits, and also have anti-interference and unique anti-electromagnetic wave interference functions.

[0003] However, in existing technologies, LED display cabinets are usually spliced ​​into an arc shape, but existing LED display cabinets have the following defects after splicing.

[0004] 1. Due to loose connections and other reasons, the gap between the two display cabinets after splicing is too large, resulting in an unsightly appearance;

[0005] 2. Generally, bolts are used to fix the splicing, which greatly affects the efficiency when assembling and disassembling.

[0006] 3. LED displays are spliced ​​using connectors, but existing splicing devices cannot accommodate connectors with different spacing. Utility Model Content

[0011] Furthermore, a rotating assembly for rotating the worm is provided on the worm.

[0012] Furthermore, the connecting pin is detachably equipped with an anti-detachment component to prevent the connector from separating from the connecting pin.

[0013] Furthermore, the anti-detachment component includes a nut or a pin.

[0014] Furthermore, each of the connecting arms is covered with a protective pad.

[0015] Furthermore, the several corresponding mounting brackets are connected by connecting rods.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an LED display cabinet arc splicing device, which has the following beneficial effects:

[0018] 1. This type of LED display cabinet arc splicing device, through the setting of worm gear, worm wheel, connecting arm and connecting pin, the worm gear can be rotated to adjust the distance between the two connecting pins, which can adapt to the connectors with different distances, improves practicality, and after the connecting pins and connectors are connected, the worm gear is rotated again to reduce the distance between the two connecting pins, which can effectively reduce the gap between the two display cabinets and make the two display cabinets more beautiful;

[0019] 2. This type of LED display cabinet arc splicing device uses a plug-in method to connect via connecting pins and sockets, replacing the traditional bolt connection method and improving connection efficiency. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-5 This utility model discloses an LED display cabinet arc splicing device, including a mounting frame 1. A worm gear 2 is rotatably mounted in the middle of the mounting frame 1, and worm wheels 3 matching the worm gear 2 are rotatably mounted on both sides of the mounting frame 1. Rotating the worm gear 2 can adjust the distance between two connecting pins 5, which can accommodate connectors 6 with different distances and effectively reduce the gap between two display cabinets. Each end of each worm wheel 3 is provided with a connecting arm 4, and each connecting arm 4 is provided with a connecting pin 5. It also includes connectors 6 installed on the display cabinet. Connectors 6 are provided with insertion holes 7 matching the connecting pins 5. The connecting pins 5 and insertion holes 7 cooperate to connect by plugging and unplugging, which improves the connection efficiency.

[0028] The worm 2 is provided with a rotating component 8 for rotating the worm 2, which makes it easy to rotate the worm 2 using a tool.

[0029] Among them, the connecting pin 5 is detachably equipped with an anti-detachment component 10, which includes a nut or a pin, and the anti-detachment component 10 prevents the connecting piece 6 from separating from the connecting pin 5.

[0030] Each connecting arm 4 is covered with a protective pad to prevent the connecting arm 4 from scratching the display screen housing.

[0031] Several corresponding mounting brackets 1 are connected by connecting rods 9.

[0032] In summary, this curved splicing device for LED display cabinets allows for adjustment of the spacing between two connecting pins 5 by rotating the worm gear 2 according to the spacing of the connectors 6. This adapts to connectors 6 with different spacings. After the connecting pins 5 are inserted into the sockets 7 of the connectors 6 and connected, rotating the worm gear 2 again reduces the spacing between the two connecting pins 5, effectively reducing the gap between the two display cabinets and making them more aesthetically pleasing.
