The invention discloses a lamp holder structure of an outdoor LED lamp. The lamp holder structure comprises an annular lamp base arranged on the top of the LED lamp, wherein an annular baffle ring is formed on the outer wall at the upper end of the lamp base; a focal length regulating sleeve is in plug bush on the lamp base; an annular blocking ring is formed on the inner wall at the lower end of the focal length regulating sleeve; a plurality of vertical cutting slots are formed in the outer wall of the lamp base; copper bars are fixedly spliced in the cutting slots of the lamp base; outer sides of the copper bars are exposed out of the outer wall of the lamp base; a plurality of blocking slots opposite to the copper bars are formed in the blocking ring of the focal length regulating sleeve; the copper bars are spliced in the blocking slots of the focal length regulating sleeve; the copper bars abut against the side walls of the blocking slots of the focal length regulating sleeve; threads are formed on inner and outer walls at the upper end of the focal length regulating sleeve; and a limiting blocking ring is in threaded connection on the inner wall at the upper end of the focal length regulating sleeve. According to the lamp holder structure disclosed by the invention, the focal length regulating sleeve and the lamp base on the head part of a flashlight are connected through the copper bars, so that positioning when the focal length regulating sleeve stretches out and draws back is convenient; and meanwhile, abrasion of the focal length regulating sleeve can be reduced, and the service life of the focal length regulating sleeve is prolonged.
Description
Technical field: [0001] The invention relates to the technical field of LED lamps, and more specifically relates to a lamp cap structure of an outdoor LED lamp. Background technique: [0002] Outdoor sports have gradually entered people's daily life.
