[0026] like Figure 1-3 As shown, a connection component includes: a connection plate 1, a plate surface of which is provided with evenly arranged first through holes 2, and the connection plate 1 is used to cover a first external panel with a second through hole 9 and a second external panel with a third through hole 10; a connection buckle 3, wherein the connection buckle 3 has two or more connection units 4 for connecting the first external panel and / or the second external panel; wherein the connection unit 4 passes through the first through hole 2 and is fixed to the second through hole 9 and / or the third through hole 10, so as to splice and fix the first external panel and the second external panel.

[0027] In view of the technical problems recorded in the background technology, a connection component is proposed, which includes a connection plate 1 and a connection buckle 3. The connection component is mainly used to splice different external panels, such as the LED light board 8 in some display devices. The first external panel and the second external panel are described below with the LED light board 8 as an application. When the LED display device is in use, a through hole is usually set on the LED light board 8, which can ensure the light transmittance on the one hand and have the effect of ventilation and heat dissipation on the other hand. When in use, the connection plate 1 used is structurally provided with a first through hole 2, and the first through holes 2 are evenly distributed on the board surface of the connection plate 1. The function of the first through hole 2 is for the connection buckle 3 to pass through and connect with the LED light board 8, so as to provide In order to increase the connection strength of the high connecting plate 1, an appropriate number of first through holes 2 can be opened according to the specific implementation situation, and there is no restriction on this. The first through holes 2 can reduce the weight on the one hand, and can also be ventilated and dissipate heat on the other hand. The connecting plate 1 is placed at the intersection of adjacent LED light boards 8, that is, the connecting plate 1 covers two LED light boards 8 respectively, and the connecting unit 4 on the set connecting buckle 3 passes through the first through hole 2 of the connecting plate 1 and the second through hole 9 and / or the third through hole 10 on the LED light board 8 to complete the connection between the connecting plate 1 and the LED light board 8, thereby realizing the splicing of adjacent LED light boards 8. Since the structure of the connecting buckle 3 and the connecting plate 1 is simpler, the splicing operation is more convenient and more suitable for practical use.

[0028] As shown in the reference figure, the connecting unit 4 includes a first clamping arm 5 and a second clamping arm 6 arranged opposite to the first clamping arm 5. The first clamping arm 5 and the second clamping arm 6 clamp the connecting plate 1 and the first and second external plates relative to each other.

[0029] At least two or more connection units 4 are arranged on the connection buckle 3. To improve the connection strength, the connection units 4 can be selected in appropriate quantity according to the actual use situation. The first external plate and the second external plate are described as LED light board 8. Of course, the first external plate and the second external plate can be plates that need to be spliced. When in use, the first clamp arm 5 and the second clamp arm 6 pass through the first through hole 2 of the connection plate 1 and the second through hole 9 and / or the third through hole 10 on the LED light board 8. By using the relative clamping effect of the first clamp arm 5 and the second clamp arm 6, the connection buckle 3 connects the connection plate 1 and the LED light board 8, and then the adjacent LED light boards 8 are spliced.

[0030] As shown in the reference figure, the ends of the first clamp arm 5 and the second clamp arm 6 are provided with a bent portion 7 bent inwardly, and the bent portion 7 is used to guide the external panel and to limit the external panel; wherein, when the connecting buckle 3 connects the connecting plate 1 and the external panel, the bent portion 7 guides the external panel to the connecting plate 1, and the bent portion 7 limits the external panel on the connecting plate 1.

[0031] The external panel is explained below as an LED light board 8. After the first clamp arm 5 and the second clamp arm 6 of the connecting buckle 3 pass through the first through hole 2 of the connecting plate 1, and the first clamp arm 5 and the second clamp arm 6 further pass through the second through hole 9 and / or the third hole 10 of the LED light board 8, due to the existence of the bend 7, during the pressing process of the connecting buckle 3, the bend 7 plays a guiding role on the one hand, so that the connecting buckle 3 can cooperate with the connecting plate 1 and the LED light board 8, and the bend 7 plays a limiting role on the other hand, and the bend 7 is set to bend inward, so that the lower edge of the bend 7 abuts against the edge of the second through hole 9 and / or the third hole 10 to achieve connection and fixation.

[0032] As a preferred embodiment, the first clamp arm 5 and the second clamp arm 6 are elastic, wherein when the connecting buckle 3 connects the connecting plate 1 and the external panel, the first clamp arm 5 and the second clamp arm 6 are expanded outward and then reset to interfere with the external panel.

[0033] The first clamp arm 5 and the second clamp arm 6 are made of a material with a certain elasticity, such as plastic or metal material. When the connecting buckle 3 is pressed, the first clamp arm 5 and the second clamp arm 6 expand outward under the action of elasticity. When pressed into place, the first clamp arm 5 and the second clamp arm 6 return to their original position under the action of elasticity, and the position of the bend 7 abuts against the edge of the second through hole 9 and / or the third hole 10, thereby clamping the LED light board and improving the firmness of the installation. The connecting buckle 3 is not easy to fall off the LED light board 8.

[0034] The following provides specific applications of connection components in LED displays. Figure 4-8 As shown, there are more than two LED light boards 8, and the LED light boards 8 are spliced ​​adjacent to each other. The holes distributed on the LED light board 8 are convenient for heat dissipation. By setting a connecting plate 1, a first through hole 2 is set on the connecting plate 1 to correspond to the hole of the LED light board 8. The connecting plate of appropriate size and specification can be selected according to usage. In addition to the first through hole 2, the connecting plate 1 can be provided with a hollow structure. The hollow structure can be a uniformly arranged hollow hole or a large area of ​​hollow. When the hollow structure adopts the hollow holes, it can be selected to correspond to the hole of the LED light board 8 to ensure the transparency of the display screen. The hollow structure can also be hollowed out in a large area on the premise of meeting the connection strength.

[0035] During use, the LED light boards 8 are arranged adjacent to each other, and the connecting plate 1 is placed at the splicing position of the adjacent LED light boards 8, that is, a part of the connecting plate 1 is placed on the first LED light board 8, and the other part of the connecting plate 1 is placed on the second LED light board 8, and the connecting unit 4 of the connecting buckle 3 is passed through the hole position of the LED light board 8 and the first through hole of the connecting plate, and the connecting plate 1 is fixed to the LED light board 8 to realize the splicing of adjacent LED light boards 8, which is more firm and easy to operate.

[0036] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
