Abstract

The invention belongs to the technical field of electric tools, and relates to a high-altitude lamp replacing device for replacing lamps. The high-altitude lamp replacing device comprises a pedestal, wherein the bottom of the pedestal is connected to an expansion link by a cardan joint; a central shaft with a hollow internal part is rotationally installed at the center of the upper part of the pedestal; a big gear, a spring, a taper sleeve, a pin and a nut are sequentially installed on the central shaft from the bottom up; the big gear is fixedly connected to the central shaft, and the central shaft is sleeved with the spring and clamped between the taper sleeve and the big gear; the taper sleeve movably sleeves the central shaft; the wall of the central shaft is provided with a pair of side openings along the axial direction from the nut position downwards, the pin is movably arranged in the side openings; a motor is also fixedly installed at the bottom of the pedestal, the power shaft of the motor passes through the pedestal, and then the small gear on the power shaft of the motor is meshed with the big gear. The high-altitude lamp replacing device can be applied to installing and uninstalling the lamps in vertical horizontal and any directions, and is wide in application range, simple in structure, low in cost and capable of being widely popularized for use.

Description

technical field [0001] The invention belongs to the technical field of electrical tools, in particular to a high-altitude lamp changer for replacing lighting lamps. Background technique [0002] With the development of modern society, various lighting fixtures are used more and more widely. Some lighting fixtures are installed in high positions and in various installation methods. It is time-consuming and laborious to manually replace the bulbs, and there is a certain danger when working at heights. Some existing devices for replacing bulbs at high altitudes can only replace bulbs installed vertically, and bulbs installed horizontally at high altitudes can only be replaced manually. The existing bulb replacement device generally rotates the bulb manually, and the degree of automation is relatively low. Contents of the invention [0003] The invention provides a high-altitude lamp changer to solve the technical problems of inconvenient disassembly and replacement of high-a...
