Description

Technical Field

[0001] The utility model relates to the technical field of artificial tree manufacturing, in particular to a branch and trunk connecting structure for artificial trees. Background Art

[0002] Existing artificial Christmas tree umbrella-shaped branch trunk connecting seats are mostly made of metal. The traditional Christmas tree umbrella connector is formed by stamping, and the iron filings are removed, and it is welded or riveted to the trunk body, and then pickled to remove rust and oil, and then sprayed with plastic or painted to prevent rust. When assembling the branch with the iron umbrella head, the hook end of the branch needs to be bent into an O shape first, and then a hollow rivet is inserted into the branch end hole and the umbrella head shaft hole, and then a special tool is used to flatten the end face of the small end of the hollow rivet so that the rivet will not fall off, so as to complete the effective anti-detachment connection between the branch and the trunk. The production process of the trunk umbrella head of the traditional Christmas tree requires stamping, chip removal, welding or riveting, rust removal, oil removal, painting and other processes. The entire production process is cumbersome and involves more machines and tools, resulting in a relatively harsh production environment. For example, the noise is loud, especially high-decibel noise is easily generated in the stamping process, and waste needs to be disposed of in a timely manner, especially the stamping process and chip removal process will produce scraps and debris. In addition, the waste liquid generated during the processing process needs to be discharged in an environmentally friendly manner, especially in the rust removal, oil prevention, painting and other processes.
