Rotatable street lamp

Abstract

The invention provides a rotatable street lamp which comprises a lamp holder, a lamp post and a rotation device. The rotation device comprises a power device, a transmission structure and a positioning lampshade, the power device can provide rotation power for the lamp holder, internal structures can be positioned under the constraints of the positioning lampshade, the positioning lampshade can prevent the internal structures from being exposed to the sun and rain, the transmission structure comprises a crank, a connecting rod, a rocker, a turbine and a worm, and the lamp holder is fixed to an end of the rocker so that the lamp holder can swing along with the rocker; a horizontal rotary shaft is arranged in the middle of the rocker so that the rocker can rotate relative to the positioning lampshade; the other end of the rocker is hinged to one end of the connecting rod, the other end of the connecting rod is hinged to the crank, the crank and the turbine are fixed to each other and can rotate around the same shaft, the worm and the turbine are matched with each other and can carry out deceleration transmission, and the power device is connected with the worm and can drive the worm to rotate.

Description

Technical field [0001] The invention belongs to the field of street lamps, and particularly relates to a rotatable street lamp. Background technique [0002] Existing street lights are generally fixedly installed on lamp posts, so that they can only illuminate one area. Most street lights are ineffective most of the time. Therefore, street lights are generally installed at a relatively large interval in places with few people. Part of the area is always dark at night, and it is difficult for travelers to find this part of the road. Summary of the invention [0003] In view of the above-mentioned prior art, the purpose of the present invention is to provide a rotatable street lamp, which can expand the lighting range at night. [0004] The technical scheme of the present invention is realized as follows: a rotatable street lamp includes a lamp cap, a lamp post and a rotating device. The rotating device includes a power device, a transmission structure and a positioning lamp shade. T...
