Embodiment Construction

[0026] like Figure 1-3 Shown is an embodiment of the screwing device of the present invention, which drives the rotating member of the lamp, such as the lamp cover, to screw it on the main body of the lamp. It can be understood that the screwing device can also drive the lamp body to screw the lamp body and the lamp cover.

[0027] like figure 1 As shown, the tightening device includes a drive assembly with a rotating shaft, and a cover 2 mounted on the rotating shaft. In this embodiment, the drive assembly is a small motor 1 , and the rotating shaft is the output shaft of the small motor 1 . It can be understood that the driving assembly may also be other forms of rotating power output assembly, such as a pulley set, a sprocket set, and the like.

[0028] The cover 2 includes a connecting portion and a receiving portion disposed on one side of the connecting portion. The cover 2 is installed on the rotating shaft through the connecting part, and the lamp cover is placed...

Abstract

The invention relates to a screwing device and a method for screwing a lamp cover onto a lamp main body. The screwing device comprises a drive component with a rotating shaft, and a cover sleeve arranged on the rotating shaft, wherein a positioning and connecting structure is arranged between the rotating shaft and the cover sleeve to make the rotating shaft drive the cover sleeve to rotate; and the cover sleeve comprises an accommodating part, and the accommodating part contacts a lamp screwing piece to generate a surface friction force driving the lamp screwing piece to rotate. The cover sleeve drives the lamp cover to rotate by placing the lamp screwing piece, such as the lamp cover on the accommodating part of the cover sleeve and using the surface friction force between the lamp cover and the accommodating part, so that the lamp cover is screwed on the lamp main body, and the defect of manual operation of workers in the prior art is avoided; the operation is simple so as to greatly improve the production efficiency; and operators cannot be hurt, and the device and the method are safe and reliable.

Description

technical field [0001] The invention relates to a lamp and its assembly tool, more specifically, to a screwing device for a lamp cover and a method for screwing the lamp cover on the lamp main body. Background technique [0002] Present lighting fixtures, especially some portable lighting fixtures (such as flashlights, miner's lamps, pilot lamps, etc.), usually include a light fixture main body and a light fixture cover, and the screw connection is realized by a threaded pair between the light fixture main body and the light fixture cover. This method of threaded connection has the advantages of convenient disassembly and assembly, good fastening performance, and can enhance the consistency of product appearance. [0003] However, during the manufacturing process of the above-mentioned lamps, workers usually manually tighten the lamp cover on the lamp main body. This assembly method has at least the following defects: because workers are required to manually tighten the lam...
