Adjusting rotary device and lamp provided with same

Abstract

The invention provides an adjusting rotary device which comprises a fixing part, a support, a rotary handle and an anti-rotation screw. The fixing part is adjacent to the support, the support is provided with an arc-shaped groove, the rotary handle and the anti-rotation screw are arranged on two sides of the arc-shaped groove respectively, the rotary handle is provided with a threaded hole from the bottom to the inside, and the anti-rotation screw penetrates a through hole formed in the fixing part and the arc-shaped groove formed in the support to be in threaded connection with the rotary handle. When the rotary handle rotates, the anti-rotation screw remains stationary. The anti-rotation screw is a unique specially-made screw, the stud portion is cut, and accordingly the screw can be prevented from rotating with the rotary handle. Angle adjustment of the support can be achieved only by loosening the threaded connection between the rotary handle and the anti-rotation screw, and accordingly the lamp illumination orientation is simply and conveniently adjusted.

Description

technical field [0001] The invention relates to a lamp, in particular to an adjusting and rotating device for a lamp bracket and a lamp with the adjusting and rotating device. Background technique [0002] In the actual use environment, lamps such as floodlights sometimes need to achieve multi-directional lighting, thus requiring the lamps to be able to change angles. In order to solve this technical problem, designs for adjusting the lighting angle of lamps have appeared in the prior art, but these designs generally require more additional components, and the operation is relatively complicated when changing the lighting angle of the lamp. At the same time, because these designs are relatively complicated, the cost of the lamp is also increased. Therefore, there are technical problems in the prior art that many components are needed to adjust the angle transformation of the lamp, and the operation is relatively complicated. Contents of the invention [0003] The object ...

Problems solved by technology

[0004] In order to solve the technical problems in the prior art that many parts are required for adjusting the angle change of lamps and the operation is relatively complicated, the present invention provides an adjusting and rotating device, which includes a fixing piece, a bracket, a rotating handle and an anti-rotating screw. The piece is adjacent to the bracket, the bracket is provided with an arc-shaped groove, the rotating handle and the anti-rotation screw are respectively arranged on both sides of the arc-shaped groove, and the rotating handle is provided with a screw thread inwardly from the bottom hole, the anti-rotation screw passes through the through hole set on the fixing piece and the arc-shaped groove on the bracket to be threadedly connected with the rotation handle; wherein, when the rotation handle rotates, the anti-rotation The rotation screw remains stationary; the anti-rotation screw includes a screw head, an end platform and a stud connected in sequence, the stud is threadedly connected with the threaded hole of the rotating handle, the end platform is waist-shaped, and the The side surface of the end table includes two substantially parallel planes and two arc surfaces connected between the two planes, and the side profile range of the end table exceeds the side profile of the stud or is consistent with the side profile of the stud flush; the through hole of the fixing member is a waist-shaped hole matching the end platform, and the end platform is arranged in the waist-shaped hole
