Description

Technical Field

[0001] The utility model relates to the technical field of Christmas tree main poles, in particular to a Christmas tree main pole splicing module. Background Art

[0002] The Christmas tree is a common decoration during Christmas. A common Christmas tree includes a base, a hollow lamp pole, branches and colored lights. The lamp pole is erected on the base, the branches are installed on the lamp pole to form a crown shape, and the colored lights are hung on the crown formed by the branches as decoration. The colored lights are connected to a power source through a power cord. The Christmas tree is large in size when assembled and is not convenient for transportation. Therefore, the Christmas tree is usually disassembled into several sections before transportation. Therefore, the colored lights hung on the tree must also be divided into several sets. After the Christmas tree is assembled, the ends of the colored lights must be connected so that they can be powered on and lit. The assembly process is relatively cumbersome.

[0003] Chinese patent number "CN116191088A" discloses a power connection device for the main pole of an artificial Christmas tree, comprising an upper main pole and a lower main pole or two or more connected main poles. The circuit of the power connection device for the main pole of the artificial Christmas tree is buried in the upper main pole and the lower main pole, and the power line between the threading hole and the light string is connected with a threaded male plug and a threaded female plug. Through this hidden circuit design, the circuit is protected, the influence of the circuit on its ornamental value is reduced, and the entanglement and knotting of the circuit is avoided to prevent the power line from short-circuiting. The device can be used for the production of the main pole of the Christmas tree, but the device does not have a modular main pole connection structure. At the same time, the connection strength between the upper and lower main poles is low, which is not convenient for assembly. In the traditional device, the electrical connection between the upper and lower main poles is inconvenient, and generally there is an exposed metal sheet, which affects the appearance and is easy to cause scratches. Therefore, an improvement is proposed to provide a spliced ​​modular main pole. Utility Model Content
