Novel table lamp with multiple adjusting and self-locking functions

Abstract

The invention relates to the technical field of lamps, and discloses a novel table lamp with multiple adjusting and self-locking functions. The table lamp comprises a base, a lifting block is movably connected to the interior of the base, an annular piece is movably connected to the right side of the lifting block, a V-shaped rod is movably connected to the right side of the annular piece, a lifting shaft is movably connected to the upper part of the V-shaped rod, and positioning gears are movably connected to the two sides of the lifting shaft. The height of the table lamp can be adjusted through cooperation of the lifting block, the annular piece, the V-shaped rod, the lifting shaft, a lifting table and a supporting column, the angle of a lamp box can be adjusted at will through cooperation of an upper vertical toothed rod, a lower vertical toothed rod, a transverse toothed rod and a push rod, and the practicability of the device is improved. The height of the lamp box is fixed through the self-locking effect of a ratchet wheel and ratchets on the outer side of the lifting shaft, the ratchet wheel and a driving gear are prevented from rotating anticlockwise through a telescopic control rod, namely, the angle of the lamp box is kept fixed, the table lamp is safer and more reliable, and the practicability of the device is further improved.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a novel desk lamp with multiple adjustment and self-locking functions. Background technique [0002] Desk lamp is a kind of lamp, which is easy to carry. It is mainly placed on the desk or dining table for lighting. The light irradiation range of the desk lamp is relatively small and concentrated, so it will not affect the light of the whole room. The function is limited to the desk lamp. around, easy to read, study, save energy. [0003] Most of the traditional table lamps do not have the adjustment function, and their use is very limited. However, some table lamps that can adjust the height and angle are complex in structure and large in size. The adjustment process is very cumbersome, and the adjustment device lacks a self-locking device, making The adjustment structure is easy to wear and tear, and it is easy to cause problems such as failure of the adjustment structure and li...
