LED lamp capable of extending or retracting and rotating conveniently

Abstract

The invention discloses an LED lamp capable of extending or retracting and rotating conveniently. A lamp body extends or retracts and rotates on a lamp holder through an extending-retracting-rotatingmechanism; the extending-retracting-rotating mechanism comprises a gear seat arranged on the lamp body; a gear is disposed in a center hole of the gear seat; deep holes are symmetrically formed in thetwo sides of the center hole and provided with elastomers; one ends of the elastomers are connected to the bottoms of the deep holes in an abutting mode, the other ends of the elastomers are connected to clamping teeth in an abutting mode, and the clamping teeth are engaged with the gear; one end of an extending-retracting rod is connected with the gear, and the other end of the extending-retracting rod is hinged to a screw rod; the screw rod is arranged on a fixing box; a first protruding column and a second protruding column extend from the two sides of the fixing box correspondingly; a first elastomer is disposed between the first protruding column and the second protruding column; a first protruding column guide track and a second protruding column guide track are symmetrically disposed on the two sides of the interior of a lamp shell of the lamp holder; and the first protruding column guide track or the second protruding column guide track comprises a first groove and a concave strip connected to the first groove. The lamp body not only can axially and freely extend or retract on the lamp holder, but also can perform 360-degree rotating illumination relative to the lamp holder and perform folding illumination. Through the simple structure, omni-directional illumination of the LED lamp is achieved.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED lamp that is convenient for telescopic rotation. Background technique [0002] Similar LED lamps in the prior art have been disclosed by the following patent documents. [0003] Chinese utility model patent specification CN 201666465U (published on December 8, 2010) discloses a rotating mechanism of a flashlight mainly composed of a housing, a base, shrapnel, and a base cover. The upper part of the housing is an accommodating cavity for installing lamps, and the lower part of the housing is rotatably hinged on the base, and a circle of spaced shallow protrusions and shallow grooves are formed around the hinge; the base is A cylindrical member, which can be sleeved on the lower part of the housing; the elastic piece can be inserted into the gap between the base and the lower part of the housing and movably locked in the shallow groove of the lower part of the housing; th...

Problems solved by technology

[0004] However, the use of such LED lights facilitates people's use to a certain extent, but because the housing can only rotate at a certain angle, its irradiation angle is still limited, thereby affecting the use effect, and further improvement is urgently needed.
