Problems solved by technology

[0002] At present, a common lamp includes a lamp bracket and a lampshade wrapped outside the lamp bracket. The length of this bracket is usually fixed, so it is often difficult to adapt when the length of the lampshade changes. In order to meet higher requirements, the existing fixed-length lamp bracket has the defect that the length is fixed and cannot be adjusted

Abstract

The invention provides a length adjusting device for a lamp support. The length adjusting device comprises a compression spring and a threaded pipe positioned in the compression spring ring, wherein one end of the threaded pipe is connected with an inner pitch thread at one end of the lamp support for fixing; the pipe body of the threaded pipe passes through a middle hole in the connecting part of a lampshade support; the lampshade support can move up and down; the compression spring sleeves the pipe body of the threaded pipe and is positioned between the lampshade support and the lamp support; the device is suitable for the variation of the distance between the lampshade support and the lamp support caused by different lampshade lengths due to the telescopic elasticity of the compression spring. The length adjusting device is smart in concept, simple in structure and convenient for production and mounting, and is a length adjusting device widely applied to the lamp support.

Description

technical field [0001] The invention relates to an adjusting device for a lamp bracket, in particular to a device installed on a lamp bracket supporting a lampshade for adjusting the length of the bracket. Background technique [0002] At present, a common lamp includes a lamp bracket and a lampshade wrapped outside the lamp bracket. The length of this bracket is usually fixed, so it is often difficult to adapt when the length of the lampshade changes. In order to meet higher requirements, the existing fixed-length lamp bracket has the defect that the length is fixed and cannot be adjusted. Contents of the invention [0003] In order to solve the above-mentioned defects, the present invention provides a length adjustment device for lamp brackets with simple structure, reasonable structure, high safety performance, and convenient installation and use. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A length adj...
