Lamp holder angle adjustment device and lamp capable of adjusting angle of lamp holder

Abstract

Provided is a lamp holder angle adjustment device and a lamp capable of adjusting an angle of a lamp holder. The lamp capable of adjusting the angle of the lamp holder comprises a lamp holder, an installing support which is used for enabling the lamp holder to be installed and the lamp holder angle adjustment device. The lamp holder angle adjustment device comprises a lamp lug seat, a support seat, a connected piece which penetrates through the lamp lug seat and the support seat to connect the lamp lug seat with the support seat together and a locking piece which locks the connecting piece. The lamp lug seat comprises an installing wall which is provided with an installing surface and a limiting seat which is placed at one side of the installing wall far away from the installing surface and limits the connecting piece to rotate relative to the lamp lug seat, wherein the support seat is installed at one side of the installing wall provided with the installing surface, the lamp lug seat is fixed or integrally formed with the lamp holder, and the support seat of the lamp holder angle adjustment device is fixed or integrally formed with the end portion of the installing support. The lamp holder angle adjustment device has the advantages of being simple in structure, low in manufacturing cost, convenient to install and use and capable of achieving lamp angle adjustment without need of using tools.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an angle adjustment device for the position of a lamp head. Background technique [0002] Most of the lamp caps and fixing brackets in the prior art are fixedly connected, and the angle of the lamp caps cannot be adjusted, so the use is limited. Even if some lamps have the function of adjusting the lamp head, their structures are complicated and the manufacturing cost is relatively high. For example, the Chinese patent application No. 201010210766.4 discloses a lamp head angle adjustment device, which includes: a fixed base 100, a rotating base 200, a connecting piece 400 passing through the fixing base 100 and the rotating base 200, and a lock connecting piece 400. The locking member 300 , the inner toothed disc 700 and the outer toothed disc 600 . The fixed seat 100 is fixedly connected with the lamp cap, and the rotating seat 200 is fixedly connected with the lamp holder. The rotating ...

AI Technical Summary

Problems solved by technology

The rotating seat 200 and the inner toothed disc 700 are fitted together, and a placement cavity 240 is provided in the rotating seat 200 to install the inner toothed disc 700, and grooves are arranged in the placement cavity 240, and convex ribs 740 are arranged on the inner toothed disc 700 , to prevent the relative rotation of the inner toothed plate 700 and the rotating seat 200, it can be seen that the structure of the rotating seat 200 and the inner toothed plate 700 is complicated, and it is more troublesome to manufacture and install, and the cost is higher

In addition, the fixed seat 100 is embedded with the outer toothed disc 600, and the fixed seat 100 is provided with a placement cavity 120 for installing the outer toothed disc 600. In order to position the two in the axial direction, the placement cavity 120 is designed as a stepped hole, so that the outer toothed disc 600 The shape of the outer wall of the gear plate 600 is adapted to it, and it is also stepped, so that the structure of this part is also very complicated and the cost is high

In addition, in order to make the locking member 400 softly release and apply the locking force, this invention also achieves this purpose by sheathing a spring 300 on the connecting member 300, but the installation and locking of the spring are inconvenient, and it is necessary to install the spring 300 on the outer tooth There is a spring cavity on the disk 600 to accommodate the spring 300, and an end cover 660 that is adapted to the end face of the external tooth disk 600 needs to be provided between the outer tooth disk 600 and the locking member 300, so that the installation of the spring part is caused. The complex structure brings troubles to manufacture

[0003] To sum up, the lamp head angle adjustment device in the prior art has a complex overall structure, high manufacturing cost, cumbersome installation, and inconvenience to use
