DETAILED DESCRIPTION

[0026] 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

[0027] See Figures 1 to 3 As shown, a telescopic lamp holder type light bulb structure includes a lamp body structure 1 and a lamp holder structure 2, wherein a telescopic channel 3 is arranged in the lamp body structure, and the end of the telescopic channel is rotatably connected to a rotating cylinder 4; in this embodiment, the rotating cylinder is a plastic structure, and the telescopic channel is a circular channel, and its inner diameter matches the outer diameter of the rotating cylinder.

[0028] At the same time, in this embodiment, the lamp holder structure 2 includes a lamp holder body 21 and a cylindrical lamp holder seat 22. When assembled and used, the lamp holder body is fixed to one end of the cylindrical lamp holder seat. In actual application, a spiral guide groove 5 is provided on the outer wall of the cylindrical lamp holder seat, and an arc-shaped protrusion 6 is fixed on the inner wall of the rotating cylinder. In this embodiment, the spiral guide groove is a double spiral guide groove, and there are two arc-shaped protrusions. When rotating, the arc-shaped protrusion moves in the spiral guide groove to enable the lamp holder seat to extend or contract. When connected, the cylindrical lamp holder seat is in the rotating cylinder, and the arc-shaped protrusion is movably arranged in the spiral guide groove. When the rotating cylinder rotates, the arc-shaped protrusion moves in the spiral guide groove and enables the cylindrical lamp holder seat to extend and retract in the telescopic channel. The above structure can realize the telescopic operation of the lamp holder body, thereby meeting the use requirements in different situations and improving the convenience and effectiveness of use.

[0029] In actual application, an annular groove 7 is provided on the inner wall of the telescopic channel; an annular protrusion 8 is provided on the outer wall of the rotating cylinder; during assembly, the rotating cylinder is arranged at the end of the telescopic channel, and the annular protrusion can be rotated and locked in the annular groove. In this embodiment, the height of the annular protrusion is relatively small, and because the rotating cylinder is a plastic structure, it has a certain extrusion deformation performance. During assembly, when a large external force is squeezed, the rotating cylinder and the annular protrusion are inserted into the telescopic channel together, and when the annular protrusion is inserted into the annular groove, it is reset to achieve a locking connection, and can be rotated and operated, and will not loosen or fall off.

[0030] In actual application, the lamp structure includes a flashlight-shaped lamp housing 11, a light source board 12 fixed in the lamp housing, a light-transmitting lampshade 13 and a reflective cup 14 positioned at the irradiation end of the lamp housing; during assembly, the reflective cup is located between the light-transmitting lampshade and the light source board; at the same time, the telescopic channel is located at the tail of the lamp housing, and a rechargeable battery 15 is arranged in the telescopic channel, and the rechargeable battery is connected to the lamp head. The lamp housing is a plastic structure or a thinner metal sheet, which also has a certain range of deformation performance, and can be quickly assembled and connected with a rotating barrel. The rechargeable battery is mainly used for electricity storage, which can ensure the effectiveness and reliability of use when the flashlight is used.

[0031] In actual application, the outer wall of the rotating cylinder is provided with a connecting convex strip 9; the outer side of the cylindrical lamp holder is provided with a protective shell 10, and the inner wall of the protective shell is provided with a vertical connecting groove 16; during assembly, the protective shell is sleeved on the outer side of the cylindrical lamp holder, and the connecting convex strip is inserted into the vertical connecting groove. Through the above structure, not only the connection and positioning of the protective shell can be realized, but also the synchronous rotation of the cylindrical lamp holder can be driven when the protective shell rotates.

[0032] For convenient use, the protective shell is buckled with a hook 17. The lamp body shell is provided with a control switch hole 18. The control switch on the control circuit board is in the control switch hole, so that the lamp can be hung for use.

[0033] The utility model has positive effects: the structure of the utility model is reasonably arranged, and the end of the telescopic channel is rotatably connected to a rotating cylinder; a spiral guide groove is arranged on the outer wall of the cylindrical lamp holder seat, and an arc-shaped protrusion is fixed on the inner wall of the rotating cylinder; when in use, the rotating cylinder rotates, the arc-shaped protrusion moves in the spiral guide groove and makes the cylindrical lamp holder seat telescope in the telescopic channel, which can realize the telescopic extension of the lamp holder structure in the telescopic channel, which not only improves the convenience of adjustment and use, but also when the flashlight is used, since the lamp holder structure is contracted in the telescopic channel, the lamp holder structure will not be damaged during use, thereby improving the effectiveness of use; when the light bulb is used, the lamp holder structure can be extended out of the telescopic channel, thereby ensuring the effectiveness and reliability of the lamp holder structure, and the applicability is strong.

[0034] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0035] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
