Upright post type LED lamp with adjustable-height lamp post

Abstract

The invention discloses an upright post type LED lamp with an adjustable-height lamp post, which comprises a lamp head, a lamp post, a mounting base and a conducting piece, and is characterized by also comprising a clamping sleeve sleeved on the lamp post, a fastening sleeve and a rotating shaft sleeve, wherein the clamping sleeve comprises a connecting sleeve and an elastic chuck which comprisesa plurality of frustum-shaped claw pieces capable of collecting elastically; an internal conical surface capable of collecting the claw pieces of the elastic chuck elastically is formed on the upper part of the inner wall of the fastening sleeve, and internal threads are formed on the lower part of the inner wall of the fastening sleeve; the rotating shaft sleeve comprises a first sleeve and a stopping disc, the first sleeve is sleeved outside the connecting sleeve, the outer wall of the first sleeve is provided with external threads for connection with the fastening sleeve; the middle part of the mounting base sinks down to form an annular concave cavity; and the stopping disc is accommodated in the annular concave cavity. Compared with the prior art, the upright post type LED lamp has the advantages that: the structure is simpler and the installation is more convenient; when the upright post type LED lamp is to be used, the fastening sleeve is rotated simply to fix the lamp post or allow the lamp post to move freely; the operation is simple; the adjustment is convenient; and the use by users is more convenient.

Description

technical field [0001] The invention relates to a lamp, in particular to a pole-type LED lamp with an adjustable lamp pole height. Background technique [0002] In daily life, the length of the light pole of many lamps is not adjustable. In actual use, sometimes for close-range lighting or to expand the lighting range, it is necessary to properly adjust the height of the light pole to obtain the best lighting effect. But the light pole of fixed length just can't realize such adjustment, brings certain inconvenience to the user. [0003] In order to improve the flexibility of the use of the lamp and facilitate the adjustment of the lamp, the Chinese utility model patent "Scalable LED Cup Lamp Lamp Shell" with the patent number ZL200620022317.6 in the prior art discloses such a lamp structure that can realize length adjustment , the lamp includes a light cup concave body, a transparent cover, a lifting tube and a matching tube with a mains power interface at one end, one open...

AI Technical Summary

Problems solved by technology

Although the above-mentioned patent can realize the adjustment of the length of the LED lamp through the telescopic lamp housing, the telescopic structure of the above-mentioned patent is only suitable for the cup lamp that needs to be installed with the lamp housing, and the telescopic structure is realized by the mutual cooperation of the lifting tube and the matching tube, and the structure is relatively It is more complicated. For ordinary pole-type LED lamps, there is no lamp shell structure. The lamp head is directly fixed on the pole, and the pole is connected with the lamp holder. Once the lamp holder is fixed and installed, the pole The height of the lamp is fixed, and the free adjustment of the height of the lamp cannot be realized
