DETAILED DESCRIPTION

[0028] 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.

[0029] Example 1

[0030] See Figures 1 to 4 As shown, a telescopic adjustable lamp structure includes an upper cover 3 and a bottom column 2 with a cavity 1, and a lamp structure 4 is arranged between the bottom column and the upper cover; in this embodiment, the bottom column and the upper cover are both metal structures or plastic structures. The upper cover is fixed to the top of the lamp structure by threading or gluing. The length of the bottom column matches the length of the lamp structure, so that the lamp structure can be completely retracted into the bottom column;

[0031] In this embodiment, the lamp structure includes a lamp holder structure 41 at the bottom, a light source 42 and a lamp tube 43 arranged between the lamp holder structure and the upper cover; in this embodiment, the light source and the lamp tube are conventional structures of the prior art, which are simply applied, and are electrically connected to an external power source through wires to realize power supply;

[0032] In actual application, a plurality of rubber rings 5 ​​are fixed on the lamp holder structure; in this embodiment, the outer diameter of the rubber ring is 0.2-2 mm larger than the inner diameter of the cavity. Thus, the rubber ring will be squeezed and deformed in the cavity to increase the friction between the rubber ring and the inner wall of the cavity. When there is no external force, the position can be completely stable, and when the external force is greater than the friction, the telescopic adjustment operation can be achieved. The thickness of the rubber ring can be processed and set as needed. In order to increase the friction, anti-slip grooves can also be added on the outer wall of the rubber ring.

[0033] In this embodiment, the shape and size of the lamp holder structure match the shape and size of the cavity; when in use, the lamp holder structure is telescopically inserted into the cavity and is pressed against the inner wall of the cavity to an upper limit position by a rubber ring.

[0034] Moreover, in this embodiment, the lamp holder structure includes a lamp holder rod 411, an end cover 412 and a connecting tube 413; wherein, external threads 414 are provided at both ends of the lamp holder rod, and internal threads 415 are provided on the inner walls of the end cover and the connecting tube; during assembly, the end cover is threadedly connected to one end of the lamp holder rod, and one end of the connecting tube is threadedly connected to the other end of the lamp holder rod, and a plurality of rubber rings are respectively located at the connection between the end cover and the lamp holder rod, and at the connection between the lamp holder rod and the connecting tube; and the rubber ring 5 is squeezed and positioned by the lamp holder rod 411 and the end cover 412, and the rubber ring 5 is squeezed and positioned by the lamp holder rod 411 and the connecting tube 413, and the end of the lamp tube is connected to the connecting tube. The above structure facilitates the disassembly, assembly, replacement and maintenance of the rubber ring, and also ensures the stability and reliability of the rubber ring.

[0035] In actual application, the cross-sections of the bottom column and the upper cover are circular or square; the cross-section of the cavity is circular or square, which can meet the use requirements of different situations.

[0036] In this embodiment, the end of the cavity is threadedly connected to a limiting convex ring 6; the lamp holder structure is located between the limiting convex ring and the bottom plate of the bottom column, and the lamp holder structure is extended and retracted in the cavity and is supported by the rubber ring on the end surface of the limiting convex ring to reach the upper limit. In this embodiment, there is a 0.1mm gap between the limiting convex ring and the lamp tube, which is mainly used to prevent the lamp tube from being limited and falling off. Through the above structure, due to the existence of the limiting convex ring, the purpose of preventing the lamp tube from falling off during extension and retraction is achieved.

[0037] The utility model has positive effects: the structure of the utility model is reasonably arranged, and the lamp structure includes a lamp holder structure at the bottom, a light source and a lamp tube arranged between the lamp holder structure and the upper cover; and a plurality of rubber rings are fixed on the lamp holder structure, and the lamp holder structure is telescopically inserted in the cavity, and is pressed against the upper limit position of the inner wall of the cavity by the rubber ring. Through the above structure, the lamp structure can be telescopically adjusted in the bottom column, which can not only meet the lighting needs, but also has the telescopic adjustment function, and during the telescopic adjustment, the adjustment limit is achieved through the extrusion and friction between the rubber ring and the inner wall of the cavity, which improves the convenience of the adjustment operation and the stability of the position after adjustment, and has strong applicability.
