Description

Technical Field

[0001] The invention relates to a limiting structure, in particular to a welding limiting structure used for a billboard. Background Art

[0002] A billboard refers to an outdoor media that transmits advertising information. Information is updated by replacing the information content in the billboard body. When making a billboard, the size of the billboard is first selected according to the needs, and then connectors are installed on both sides of the billboard. After the installation is completed, the billboard is moved to a designated location and connected to the advertising support rod through the connector. The existing method of connecting the connector to the billboard is to directly assemble the connector and the billboard manually by an operator (during assembly, the extension rod of the connector needs to correspond to the limit groove of the billboard, and the connector is hit by a rubber hammer to insert the extension rod into the limit groove), and then the connector and the billboard are welded together; in this connection method, on the one hand, when the connector is hit by a rubber hammer to insert the extension rod into the limit groove, the billboard and the connector are manually positioned by the operator, which is not only labor-intensive but also has a poor splicing effect; on the other hand, the connector and the billboard cannot be positioned during welding, resulting in poor welding effect.
