Description

Technical Field

[0001] The utility model relates to the technical field of LED explosion-proof lamps, in particular to an angle-adjustable LED explosion-proof lamp. Background Art

[0002] After my search, application number 202320085082.9 discloses an adjustable angle LED explosion-proof lamp, including a cabinet and a frequency converter installed in the cabinet. The front end of the cabinet is rotatably connected to the cabinet door through a hinge, and transversely arranged box bodies are provided on the upper and lower sides of the rear end of the cabinet, and the opening of the box body is arranged backward. The inside of the box body is rotatably connected to a transversely arranged bidirectional screw, and the outer end of the bidirectional screw is symmetrically threadedly connected to two nut seats, and the two nut seats are both slidably connected in the box body.

[0003] In the comparative document, an adjustable-angle LED explosion-proof lamp is used. The threaded rod is driven to rotate by the power of the second motor, so that the threaded sleeve threadedly connected to the threaded rod drives the bottom of the LED light board to move upward through the lifting block, and the angle of the LED light board is adjusted with the cooperation of the slider driving the top of the LED light board to slide left and right. However, during such use, the device can only adjust the angle of the lighting direction of the LED light board within the range of inclined downward, and cannot adjust the angle of the lighting direction of the LED light board within the range of inclined upward, resulting in reduced applicability of the device. In addition, the device drives the bottom of the LED light board to move through the lifting block, thereby forcing the top of the LED light board to move in coordination, which is easy to squeeze or pull the LED light board and cause damage, thereby reducing the service life of the device. For this reason, we propose an adjustable-angle LED explosion-proof lamp. Utility Model Content

[0014] 1. The angle-adjustable LED explosion-proof lamp is provided with an adjustment mechanism. When in use, the output end of the driving motor can be controlled to drive the supporting rotating column to rotate. The supporting rotating column drives the LED explosion-proof lamp board to rotate in the horizontal direction through the adjusting shell, the circular arc slide, the circular arc slide plate and the mounting plate, so that the device can adjust the angle of the lighting direction of the LED explosion-proof lamp board in the horizontal direction. The output end of the adjusting motor can be controlled to drive the driving worm to rotate. The driving worm drives the adjusting gear on the adjusting rotating rod to rotate through the driving worm wheel, forcing the circular arc slide plate meshing with the adjusting gear through the adjusting tooth groove to slide up and down along the circular arc slide, thereby driving the LED explosion-proof lamp board on the mounting plate to tilt, so that the device can adjust the angle of the LED explosion-proof lamp board in the vertical direction. The above operation is simple and convenient, which improves the angle adjustment range of the LED explosion-proof lamp board of the device and improves the applicability of the device.

[0015] 2. This angle-adjustable LED explosion-proof lamp is equipped with a rolling wheel. The left end of the arc-shaped slide groove is in rolling contact with the side of the arc-shaped slide plate that is biased towards the axis through the installation groove, thereby reducing the resistance encountered by the arc-shaped slide plate when moving up and down, making the device smoother in adjusting the angle of the LED explosion-proof lamp panel.
