Description

Technical Field

[0001] The utility model relates to the technical field of floor lamp connectors, in particular to a floor lamp base connection structure. Background Art

[0002] With the improvement of living standards, people's requirements for home lighting equipment are getting higher and higher. As a common home lighting equipment, the stability and adjustment flexibility of the base connection structure of the floor lamp directly affect the use effect and user experience. The existing floor lamp base connection structure generally connects the lamp pole to the base through a connector. For details, please refer to the floor lamp disclosed in the Chinese patent application number CN202222287224.8, including a base, a light-transmitting tube assembly, a uniform light tube and at least one light strip. The floor lamp also includes an axial direction, and the light-transmitting tube assembly is parallel to the axial direction; one end of the light-transmitting tube assembly is installed on the base, and the uniform light tube is inserted in the light-transmitting tube assembly, and the at least one light strip is inserted in the light-transmitting tube. The connector in this structure is connected to the light-transmitting tube assembly by threaded fitting to fix it.

[0003] This structure can improve the connection stability to a certain extent, but during assembly, it is necessary to pick up the base and tighten the connector and the light-transmitting tube assembly, or place the base on a platform, pick up the light-transmitting tube assembly and connect it with the connector to tighten it. At that time, no matter which of the above methods is used, it is necessary to ensure that the central axis of the connector and the central axis of the light-transmitting tube assembly are in the same straight line while tightening, otherwise the two cannot be completely tightened with a slight deviation, and multiple attempts may be required, which will not only delay the assembly and affect the efficiency, but multiple attempts may also cause damage to the threaded structure inside the connector or the light-transmitting tube assembly, resulting in failure to connect normally.

[0004] In addition, the above patent application also mentions that a tight fit can be used for connection. This connection method can achieve a tightening effect in the short term, but after long-term use, the light-transmitting tube assembly will be deformed due to the connector, resulting in loose connection and lack of stability.
