Description

Technical Field

[0001] The utility model relates to the field of lamps, in particular to a detachable rotating shaft for a rotating lamp. Background Art

[0002] Lamps are a general term for lighting tools, which are divided into chandeliers, table lamps, wall lamps, floor lamps, etc. It refers to an appliance that can transmit light, distribute and change the light distribution of a light source, including all parts required to fix and protect the light source except the light source, as well as the line accessories necessary for connecting to the power supply.

[0003] Currently, there is a rotating lamp, which is connected to the light source through a motor shaft, and the light source is driven to rotate through the shaft. However, the connection between the light source and the shaft is mostly fixed, or inconvenient to disassemble, which is not conducive to subsequent maintenance and replacement, and is therefore inconvenient to use. Accordingly, the utility model proposes a detachable shaft for a rotating lamp to solve the above problem. Utility Model Content

[0004] In order to overcome the defects in the above-mentioned prior art, the utility model provides a detachable rotating shaft for a rotating lamp, which transmits torque through a connecting groove and locks the light source part through a threaded segment and a nut, thereby realizing quick disassembly and assembly of the rotating shaft and the light source part, facilitating subsequent maintenance or replacement of the light source.

[0005] Technical Solution

[0006] A detachable rotating shaft for a rotating lamp comprises a first shaft segment, one side of the first shaft segment is connected to a second shaft segment, the other end of the second shaft segment is provided with a third shaft segment, the other end of the third shaft segment is connected to a threaded segment, and connecting grooves are provided on the threaded segment and the third shaft segment.

[0007] Furthermore, the connecting groove includes a transmission portion located on the third shaft segment and a sliding portion located on the threaded segment.

[0008] Furthermore, a circumferential annular groove is provided between the second shaft segment and the third shaft segment.

[0009] Furthermore, the first shaft segment is provided with four ribs in an annular array.

[0010] Furthermore, an end of the first shaft segment away from the second shaft segment is provided with a chamfer.

[0011] Furthermore, there is no burr at the connection between the threaded section and the sliding portion.

[0012] Beneficial Effects

[0013] Compared with the prior art, the utility model has the following beneficial effects: torque is transmitted through the connecting groove, and the light source part is locked through the threaded section and the nut, thereby realizing quick disassembly and assembly of the rotating shaft and the light source part, and facilitating subsequent maintenance or replacement of the light source.

[0019] In order to better illustrate the content of the utility model, the following is a description with reference to the accompanying drawings and implementation examples:

[0020] have Figure 1-Figure 3 As shown, the utility model discloses a detachable rotating shaft for a rotating lamp, including a first shaft segment 1, one side of the first shaft segment 1 is connected to a second shaft segment 2, the other end of the second shaft segment 2 is provided with a third shaft segment 3, the other end of the third shaft segment 3 is connected to a threaded segment 4, and the threaded segment 4 and the third shaft segment 3 are provided with a connecting groove 5.

[0021] Furthermore, the connecting groove 5 includes a transmission portion 51 located on the third shaft segment 3 and a sliding portion 52 located on the threaded segment 4 .

[0022] Furthermore, a circumferential annular groove 7 is provided between the second shaft segment 2 and the third shaft segment 3 .

[0023] Furthermore, four ribs 8 are arranged in an annular array on the first shaft section 1 .

[0024] Furthermore, a chamfer 9 is provided at one end of the first shaft segment 1 away from the second shaft segment 2 .

[0025] Furthermore, there is no burr at the connection between the thread segment 4 and the sliding portion 52 .

[0026] Specifically, when in use, the threaded segment 4 is inserted into a connecting component containing an inner hole, on which a light source is provided, until the connecting component abuts against the transmission part 51, and the shape of the inner hole of the connecting component is the same as the cross-sectional shape of the transmission part 51, and the two can fit exactly together, thereby transmitting torque, and then a fixing nut is screwed into the threaded segment 4 until the nut abuts against the outer side surface of the connecting component, thereby fixing the connecting component and quickly connecting the connecting component to the rotating shaft. When it needs to be disassembled, the connecting component can be taken out after unscrewing the nut, that is, the light source is removed, which is convenient for subsequent replacement or repair.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the technical solution of the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
