DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0041] See Figures 1 to 7 As shown, a combined table lamp structure includes a base 1, a lamp pole 2, a connecting support plate 3 and a lamp body 4. In this embodiment, the base can be round, square or other common shapes, and the lamp pole is molded in one piece. The lamp pole is a metal lamp pole or a plastic lamp pole. And the lamp pole is a truncated cone-shaped pole with a small top and a large bottom;

[0042] In actual application, the base is rotatably connected to a mounting convex cylinder 6 through an axle rod 5. When disassembling or assembling, the bottom end of the lamp pole is plugged into the mounting convex cylinder. In actual application, in order to improve the convenience and stability of installation, an annular groove 7 is provided on the upper part of the outer wall of the mounting convex cylinder, and a buffer groove 8 is provided on the top of the mounting convex cylinder. A positioning convex ring 9 is provided on the inner wall of the bottom end of the lamp pole. The mounting convex cylinder is inserted into the bottom end of the lamp pole, and the positioning convex ring of the lamp pole is clamped into the annular groove for limiting position. The outer diameter of the mounting convex cylinder matches the inner diameter of the bottom end of the lamp pole. When the bottom of the lamp pole is sleeved on the mounting convex cylinder, the upper part of the mounting convex cylinder will be squeezed. After the positioning convex ring is clamped into the annular groove, the mounting convex cylinder is reset under the action of its own elastic force, thereby ensuring the reliability of installation and preventing loosening or falling off.

[0043] In actual application, the top side of the lamp pole is provided with an L-shaped connection groove 10, and the L-shaped connection groove is rotatably connected with a connector 12 through a pin shaft 11; two supporting bosses 13 and a threading hole 14 are fixed on the top of the connector; the top of the connector is snapped with a limit cover plate 15, and the limit cover plate is provided with a support hole 16 and a circular through hole 17; during assembly, the supporting bosses of the connector are snapped into the support holes and positioned, and the connection support plate is clamped and limited by the connector and the limit cover plate; the lamp body is rotatably connected to the bottom surface of the other end of the connection support plate through a convex shaft 18. The threading hole and the circular through hole are mainly used for the threading connection of wires to ensure the effectiveness of wiring. The connector is rotatably connected to the L-shaped connection groove through a pin shaft, so that it can be rotated within a right angle range to meet the use requirements of different situations.

[0044] In actual application, the connecting support plate includes a supporting base plate 31 and a decorative cover plate 32 fixed by screws; and circular holes 33 are provided at both ends of the supporting base plate; when installed and used, a convex ring is integrally formed on the top surface of the connecting head, and the convex ring and the convex shaft can be rotatably arranged in the two circular holes respectively. It can not only improve the decorative performance, but also can be rotated and adjusted as needed to meet the use requirements of different situations.

[0045] In order to improve the effectiveness of rotation adjustment, an arc-shaped guide groove 19 is provided on the inner wall of the circular hole; and a limiting convex block 20 is fixed on the outer wall of the convex ring and the convex shaft. When the convex ring and the convex shaft rotate in the circular hole, the limiting convex block rotates in the arc-shaped guide groove and is pressed and limited by the end wall of the arc-shaped guide groove. The rotation can be limited so that it rotates within a certain range.

[0046] Meanwhile, in actual application, the bottom surface of the base is provided with a cavity 21 and a bottom plate 22; a circuit board and a power supply are fixed in the base, and a control button 23 connected to the circuit board is provided on the base; and the wires of the lamp body pass through the lamp pole and the connecting support plate and are electrically connected to the circuit board in the base. The circuit board and the power supply are conventional structures of the prior art, and are simply applied, so they are not recorded in detail.

[0047] In actual application, a plurality of support bars 24 are integrally formed in the cavity, and a wire clamping slot 25 is provided on the support bar. The wire can be clamped to prevent its pulling performance, and it is also beneficial to protect the wire and ensure the connection stability of the connection point.

[0048] In this embodiment, the lamp body includes a lamp housing 41, a light source board 42 and a light-transmitting panel 43; in actual application, the bottom surface of the lamp housing is provided with an eight-shaped lamp cavity 44 with a small top and a large bottom; the width of the light source board is larger than the top width of the eight-shaped lamp cavity and smaller than the bottom width of the eight-shaped lamp cavity; the light-transmitting panel is snapped into the bottom end of the eight-shaped lamp cavity; the light source board is fixed in the eight-shaped lamp cavity by screws; the convex shaft is in the middle of the top surface of the lamp housing. Through the above structure, when the screws are tightened, the edge of the light source board will gradually press against the inner wall of the eight-shaped lamp cavity, ensuring the stability of the connection of the light source board and preventing it from loosening or falling off.

[0049] The utility model has positive effects: the structure of the utility model is reasonably arranged, and the lamp pole can be quickly inserted and positioned on the mounting boss, and the lamp pole can be quickly connected to the connecting support plate through a connecting head, and the lamp body can be rotatably connected to the connecting support plate, which improves the convenience and stability of disassembly and assembly, and is conducive to local replacement or maintenance operations.
