LED desk lamp with height capable of being stably adjusted

Abstract

The invention relates to the technical field of LED devices and discloses an LED desk lamp with the height capable of being stably adjusted. The LED desk lamp with the height capable of being stably adjusted comprises a base; an installing plate is fixedly connected to the upper surface of the base; a fixed plate is fixedly connected to the upper surface of the installing plate; an inner groove isformed in the fixed plate; a through groove communicated with the inner groove is formed in the top of the fixed plate; a movable plate is connected in the through groove in an inserted manner; the bottom of the movable plate extends to the inner groove and is fixedly connected with a baffle located in the inner groove; and the two side faces of the baffle are each provided with an insetting groove. According to the LED desk lamp with the height capable of being stably adjusted, by arranging a fastening nut, a limiting ball, a telescopic spring and a limiting groove, limiting and speed reducing are performed in the adjusting process through the limiting groove and the limiting ball, and therefore stability is enhanced; and meanwhile, in cooperation with the fastening nut, fixing on the movable plate can be more stable, that the phenomenon that because an LED lamp bulb bears the gravity, the movable plate moves downwards is prevented, and therefore the effect of stably adjusting the height is achieved.

Description

technical field [0001] The invention relates to the technical field of LED equipment, in particular to an LED table lamp whose height can be stably adjusted. Background technique [0002] Desk lamp is a kind of lamp, small and exquisite, easy to carry. This electrical appliance is mainly placed on the desk or dining table for lighting purposes. The light range of the desk lamp is relatively small and concentrated. The desk lamp is mainly for decoration and will not affect The light of the whole room is limited to around the desk lamp, which is convenient for reading, studying, working and saving energy. Most of the desk lamps on the market are LED desk lamps, but most of the support rods of the LED desk lamps on the market are carat tubes. The characteristics of the LED desk lamp can adjust the lighting height and angle of the desk lamp. However, due to the influence of gravity, after a long time of use, the support rod of the LED desk lamp is prone to bend downwards, result...
