Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] Such as Figure 1 to Figure 4 As shown, the embodiment of the present invention includes a first connecting body 1 and a second connecting body 2 .

[0026] The first connecting body 1 includes a shaft body 101, a limiting portion 102, a connecting portion 103, and an indented portion 104; the limiting portion 102 is arranged on both sides of the shaft body 101 on the shaft body 101, and the upper end of the limiting portion 102 is provided with a connecting portion 103. The shaft body 101 generally adopts a cylindrical shape to increase smoothness of rotation, but a columnar structure such as a prism can also be used.

[0027] The second connecting body 2 includes a rotating cavity 201 , a bayonet socket 202 , a stabilizing platform 203 and a blocking platform 204 . The bayonet 202 is arranged on the upper part of the rotating cavity 201, and the s...

Abstract

The invention provides a rotating shaft connecting structure and belongs to the field of LED lamp structural parts. The rotating shaft connecting structure comprises a first connector and a second connector; the first connector is locked with the second connector; the rotating shaft connecting structure is characterized in that the first connector comprises a shaft body, a narrow-wide part is arranged on the shaft body, the second connector comprises a rotating chamber, a bayonet is arranged on the upper part of the rotating chamber, the shaft body is rotataby connected with the rotting chamber, and the width of the narrow-wide part is smaller than or equal to the width of the bayonet. The rotating shaft connecting structure is capable of reliably connecting the various parts of a lamp housing while remaining the rotation function by only depending on structure cooperation and the position relation of the various parts, and also capable of realizing simultaneously separation of a plurality of rotating shafts.

Description

technical field [0001] The invention belongs to the field of structural parts of LED lamps, and in particular relates to a rotating shaft connection structure. Background technique [0002] The shell of LED lamps usually includes a cover and a back cover. If the connection between the cover and the back cover is fastened by screws, the production efficiency will be reduced, and the tightness between multiple screws can also be kept consistent. The inconsistencies in the bonding tightness at various points of the bonding surface have been caused, which affects the waterproofness of the lamp. In the prior art, a rotating shaft is used to connect the front cover and the back cover, and the front cover and the back cover are pressed tightly by the principle of leverage, so that the force is evenly distributed from both ends of the joint surface to the center. However, the rotating shaft used in the prior art is usually riveted with rivets. This makes the disassembly and assembl...
