Hinge device for lamps

Abstract

The invention discloses a lamp hinge device. According to the lamp hinge device, a lamp is provided with a first adjusting rod and a second adjusting rod which are capable of mutually rotating to adjust the illuminating angles of a lamp holder, the hinge device is arranged on the connection position of the first adjusting rod and the second adjusting rod to enable the happening of front and reverse rotation between the first adjusting rod and the second adjusting rod, and then the illuminating angles of the lamp holder are adjusted; the hinge device comprises a first adjusting base, a second adjusting base, a gear device, a friction plate, a button component and a connection component, wherein the first adjusting base is embedded into the first adjusting rod, the second adjusting base is embedded into the second adjusting rod, the gear device is arranged between the first adjusting base and the second adjusting base and capable of enabling the happening of relative rotation between the first adjusting base and the second adjusting base, the friction plate is made of wear-resistant materials and clamped between the first adjusting base and the second adjusting base, and the functions of preventing abrasion and filling gaps to enable connection to be firm and stable are achieved by the friction plate, the button component is arranged on the outer side of the first adjusting base and capable of pushing the gear device to move, and the connection component is arranged on the outer side of the second adjusting base.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a hinge device of a lamp. Background technique [0002] Lamps are indispensable electrical appliances in people's daily work and life. With the improvement of living standards, people's requirements for lamps are getting higher and higher, such as table lamps, floor lamps, wall lamps and other lamps. 1. The irradiation angle can be flexible and changeable, and various irradiation angles can be converted according to personal preferences. Some existing lamps can also change the irradiation angle through the joint structure, but the existing joint structure is often too complicated so that the production cost is high, and The operation steps are cumbersome and complicated; some joint structures are too rough and simple, and the angle of the adjustment rod is only adjusted by the tightness of the screw at the joint part. Long-term use is prone to loosening or slipping, making the adju...

[0002] Lamps are indispensable electrical appliances in people's daily work and life. With the improvement of living standards, people's requirements for lamps are getting higher and higher, such as table lamps, floor lamps, wall lamps and other lamps. 1. The irradiation angle can be flexible and changeable, and various irradiation angles can be converted according to personal preferences. Some existing lamps can also change the irradiation angle through the joint structure, but the existing joint structure is often too complicated so that the production cost is high, and The operation steps are cumbersome and complicated; some joint structures are too rough and simple, and the angle of the adjustment rod is only adjusted by the tightness of the screw at the joint part. Long-term use is prone to loosening or slipping, making the adjustment rods unable to be firmly positioned and not durable enough. Durable, affecting the service life, and the screw needs to be loosened and tightened before and after turning the adjustment lever, the operation is cumbersome and time-consuming
