Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a lamp slot connection assembly. Background Art

[0002] The column lamp is composed of a column and a lamp slot. A lamp board and a light guide plate are arranged in the lamp slot. One end or both ends of the lamp slot are respectively connected to the column, and an L-shaped lamp or a door-shaped lamp can be formed. The lamp slot can rotate relative to the column to adjust the rotation angle.

[0003] In the prior art, the lamp slot and the column are connected by a rotating pin. An installation hole is arranged inside the column, and one end of the rotating pin is fixed in the through hole of the end cap. A plurality of elastic pin pieces are arranged at the other end of the rotating pin. During assembly, the end of the rotating pin with elastic pin pieces is inserted into the installation hole of the column, and the elastic pin pieces are compressed and deformed to provide a pre-tightening force to assemble the lamp slot on the column. When the lamp slot needs to be rotated, a torque greater than the pre-tightening force is applied to the lamp slot, and the lamp slot can be rotated.

[0004] The defect of the prior art is that the rotating pin and the column are only connected by the pre-tightening force of the elastic pin pieces, lacking axial limit. When applying force to rotate the lamp slot, since the direction of the user's applied force may be inclined, the rotating pin may be subjected to an axial tensile force, and the end of the rotating pin with elastic pin pieces may come out of the installation hole, resulting in the separation of the lamp slot and the column and affecting the normal use of the product. If the pre-tightening force of the elastic pin pieces is large enough, the user needs to use a large torque to rotate the lamp slot, which affects the user experience. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a lamp slot connection assembly.
