Description

A kind of telescopic light bulb
Technical field
The utility model is related to field of lighting devices, and in particular to a kind of telescopic light bulb.
Background technology
Since light bulb is by invention, electric light just becomes illumination indispensable in people's routine work and life and sets It is standby.With the development of the social economy, the raising of people's living standard, various festive lantern, desk lamp also come into being, to people's Life adds many colors, and under the premise of Electrical Safety is ensured, people increasingly focus on the appearance and functionality of light bulb.So And the existing most structure of light bulb is single, length is fixed, and light bulb length can not be adjusted, and is stored inconveniently, and influences people's life just Sharp degree, especially light bulb as student's reading and writing illuminations in use, fixed light bulb can not often provide fills The illumination of foot, the unsighted gear of student, school environment is dark, is easily impacted to child's eyesight.
Utility model content
To improve the deficiencies in the prior art, the utility model provides a kind of telescopic light bulb.Pass through the utility model Expansion bracket, can adjust light bulb entire length, realize the illumination zone for adjusting light bulb, provided preferably for student's reading and writing Brightness.
In order to achieve the above object, the technical solution that the utility model is taken is:A kind of telescopic light bulb, including light bulb With expansion bracket, the expansion bracket includes interior telescopic rod, external extension bar two parts;The interior telescopic rod is placed in inside external extension bar; The light bulb is fixedly installed in interior telescopic rod top;The external extension bar inner wall is equipped with the helical orbit of two recess, described Two helical orbit reverse symmetry distributions;It is set on the interior telescopic rod outer wall there are two symmetrical protrusion, the protrusion is embedded in On the helical orbit, and can be along helical orbit lifting moving.
The above structure of the utility model, on interior telescopic rod setting can be embedded in it is convex on external extension bar helical orbit Rise, by telescopic rod inside and outside rotation, and pass through protrusion on the helical orbit of reverse symmetry the interior telescopic rod of rotational slide with Upper and lower displacement variation occurs for external extension bar, it is achieved thereby that the Telescopic of light bulb entirety, is convenient for people to carry out light bulb length Adjustment, is more convenient to be illuminated, can preferably protect the eyesight of child in student's reading and writing or family learning.
Further, the card slot that the helical orbit top setting is lateral, the rectangular preiection can be placed in inside card slot, When telescopic rod stretches out upwards in protrusion drive, available for interior telescopic rod is fixed.
Further, the light bulb includes lamp holder, wick and lampshade, the lamp holder rotation is installed on the interior of interior telescopic rod Portion upper end, it is convenient to carry out demolition and replacement to light bulb.
Further, the lamp holder is equipped with the first screw thread, the interior telescopic rod inner upper end is equipped with and lamp holder first The second screw thread that screw thread matches, light bulb can be turned round by the second screw thread rotation on the first screw thread on lamp holder and interior telescopic rod Tightly.
Further, the external extension bar is made of insulating materials, guarantee safety.
Further, the interior length of telescopic bar is the 3/4 of external extension pole length, it is convenient preferably adjust light bulb away from From providing more comfortable illumination condition.
The beneficial effects of the utility model are:The utility model passes through the helical orbit that reverse symmetry is set to be distributed, reality Show the moving in rotation between interior telescopic rod and external extension bar, so as to which the light bulb on interior telescopic rod be driven to be lifted, convenient pair Light bulb distance is adjusted, and provides more comfortable light environment for student's reading and writing, preferably protects the eyesight of child.
