Liftable three-dimensional eye protection table lamp

Abstract

The invention discloses a liftable three-dimensional eye protection table lamp which comprises a fixing sleeve, a table lamp body and a fixing clamp. The table lamp body is arranged above the fixing sleeve; and track plates are mounted on the two sides of the bottom of the adjusting plate correspondingly, and a movable gear and a meshing gear are arranged in the middle of the interior of the fixing sleeve correspondingly. Through the arrangement of a fixing sleeve and a movable sleeve, the movable gear and the meshing gear can play a certain supporting role according to own characteristics so that a user can quickly adjust the height of the device, in addition, a pressing piece, a push rod, a push plate, the movable gear and the meshing gear are matched to work, the movable gear and the meshing gear can be separated from the track plates, the track plates can fall down according to the gravity of the track plates so as to drive the adjusting plate to complete resetting, the limiting plate can extrude the return spring in the backward moving process of the push rod, the return spring can drive the push rod to reset according to the elasticity of the return spring, and therefore a user can conveniently use next time.

Description

technical field [0001] The invention relates to the technical field of eye protection table lamps, in particular to a liftable three-way eye protection table lamp. Background technique [0002] "Eye protection table lamp" is mainly composed of two parts: light source and lamp. The lamp head is usually a light source with better light quality. The lamp is a lampshade that can improve the uniformity of light distribution and weaken or reduce glare, and provide current to the light source. Composition of drive circuit. [0003] The defective that exists in a kind of existing three-protection eye desk lamp is: [0004] 1. The comparative document CN211902780U discloses a rotating mechanism for an eye-protecting desk lamp, "including an upper cover, a rotating bearing, an independent rebound column and a base, a group of movable through holes are arranged on the inner bottom surface of the upper cover, and a set of movable through holes are arranged inside the movable through ho...

AI Technical Summary

Problems solved by technology

In short, the non-radiation eye-protecting table lamp has a reasonable structural design, is easy to use, does not hurt the eyes, and is suitable for popularization." Fast with other objects, has certain limitations in actual use

[0007] 4. The comparative document CN107166212A discloses a multifunctional eye-protecting desk lamp, "including a lamp holder, a lampshade, and a light source; the lamp holder is connected to the lampshade, and it also includes an ultrasonic sensor, a brightness adjustment knob, a timer, and an alarm lamp group , a controller, the ultrasonic sensor, the timer, and the alarm lamp group are connected to the controller respectively; the multifunctional eye protection table lamp also places the ultrasonic sensor at the position where the edge of the lampshade is the shortest from the user’s straight line distance; the ultrasonic sensor The function is to detect the distance between the person and the lamp, the distance data is transmitted to the controller, and the controller judges whether there is a person in front of the lamp according to the set data range; when there is a person, the controller judges whether it meets the set distance for eye protection, and simultaneously The timer starts counting, and the alarm lamp group is used to give an alarm when the user uses it for too long or the distance is lower than the set distance or when the distance is higher than the set distance; the controller and the timer are arranged on the lamp holder "inside", but the overall adjustment ability of the device is poor, making it difficult to quickly adjust according to the irradiation angle required by the user, which easily affects the work efficiency of the user
