[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The utility model relates to a lamp wire fixing structure, comprising a lamp body 100 and a fixing member 200.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the shape of the lamp body 100 is not limited. The lamp body 100 can be the main body of various lamps such as downlights and chandeliers. The lamp body 100 can be an integrally formed main body, or a main body assembled from different components. A mounting hole 110 is provided on the lamp body 100. A threading hole 210 is provided on the fixing member 200. The fixing member 200 can be plugged into the mounting hole 110. When the fixing member 200 is inserted into the mounting hole 110, the inner wall of the mounting hole 110 squeezes the side wall of the fixing member 200, causing the threading hole 210 to shrink radially. During assembly, the fixing member 200 is first detached from the mounting hole 110. The wires of the electrical components in the lamp are led out to the outside of the lamp body 100 through the mounting hole 110 and the threading hole 210 in turn. Then the fixing member 200 is inserted into the mounting hole 110. The fixing member 200 is squeezed and contracted by the mounting hole 110, and the portion of the wire passing through the threading hole 210 is clamped, thereby completing the wire fixing operation. The fixing member 200 closes the mounting hole 110, and the inner wall of the threading hole 210 abuts against the outer wall of the wire, which is equivalent to closing the threading hole 210, thereby preventing mosquitoes or dust from entering the interior of the lamp body 100 through the mounting hole 110 or the threading hole 210.

[0028] The material of the fixing member 200 may be elastic materials such as silicone, rubber, etc. to achieve compression and contraction of the threading hole 210. Figure 3 and Figure 4 As shown, the fixing member 200 includes a plurality of petals 220. The plurality of petals 220 are sequentially distributed along the circumference of the fixing member 200. Two, three or more petals 220 can be provided. There is a certain interval between adjacent petals 220, and an expansion and contraction gap 230 is formed at the interval. A threading hole 210 is defined between each petal 220. When not subjected to external force, each petal 220 is separated from each other. When the mounting hole 110 is inserted after the wire is threaded, the petal 220 extends into the mounting hole 110, and each petal 220 is squeezed by the mounting hole 110 and gathered toward the central axis direction of the threading hole 210, and each expansion and contraction gap 230 becomes smaller, thereby causing the threading hole 210 to shrink. Each petal 220 cooperates to clamp and fix the wire.

[0029] Further, such as Figure 2 , Figure 3 and Figure 4 As shown, the fixing member 200 also includes a limit head 240. Each petal body 220 extends axially from the limit head 240. That is, one end of the petal body 220 is connected to the limit head 240, and the other end serves as a free end. The threading hole 210 passes through the limit head 240. The wire passes through the threading hole 210 from the side where the free end of the petal body 220 is located, and then passes out from the limit head 240. During installation, each petal body 220 can be extended into the mounting hole 110 for folding. The limit head 240 abuts against the end of the mounting hole 110. The mounting hole 110 can be set as a stepped hole, and the limit head 240 sinks and abuts in the large-diameter section of the stepped hole. The mounting hole 110 can also be a straight through hole, and the limit head 240 abuts on the outer side of the end of the mounting hole 110. The limit head 240 is used to limit the stroke position of the fixing member 200 inserted into the mounting hole 110. Specifically, the limit head 240 is in the shape of a hollow ring, and the hollow part is a part of the threading hole 210. The positions where the petals 220 are distributed are on a circumference. The outer diameter of the limit head 240 is larger than the outer diameter of the circumference where the petals 220 are located. The outer diameter of the limit head 240 is larger than the aperture of the mounting hole 110. The limit head 240 abuts against the outer side of the end of the mounting hole 110. Furthermore, a chamfer 241 is provided at one end of the threading hole 210 located at the limit head 240, and the chamfer 241 can be an arc angle, etc. After the wire passes through the limit head 240, a part of the wire will abut against the chamfer 241, and the chamfer 241 can reduce scratches on the wire.

[0030] In some specific embodiments of the present invention, Figure 3 , Figure 4 and Figure 5 As shown, a hook portion 250 is provided on the petal body 220. One, two or more hook portions 250 may be provided on the petal body 220. When a plurality of hook portions 250 are provided on a petal body 220, the hook portions 250 are distributed in sequence along the length direction of the petal body 220 (i.e., the axis of the threading hole 210). A card slot 111 is provided on the inner wall of the mounting hole 110. When the petal body 220 is inserted into the mounting hole 110, the hook portion 250 can be snapped into the card slot 111, thereby limiting the fixing member 200 from axially disengaging from the mounting hole 110, thereby ensuring the stability of the fixed line during use. Specifically, as Figure 5As shown, the cross section of the hook portion 250 along the axial direction of the fixing member 200 includes a clamping surface 251, a connecting surface 252 and an inclined surface 253. The clamping surface 251 is closer to the limit head 240 than the inclined surface 253. The clamping surface 251 is arranged perpendicular to the axial direction of the fixing member 200. The inclined surface 253 is inclined toward the other side from the side close to the clamping surface 251 to gradually approach the central axis of the fixing member 200. That is, in the direction shown in the figure, the side of the inclined surface 253 close to the clamping surface 251 is the upper side, and the upper side of the inclined surface 253 is farther away from the central axis of the fixing member 200 than the lower side. The connecting surface 252 is connected between the clamping surface 251 and the inclined surface 253. The connecting surface 252 can be arranged parallel to or slightly inclined to the axial direction of the fixing member 200. During the process of inserting the petal body 220 into the mounting hole 110, the inclined surface 253 first enters the mounting hole 110, and then the inclined surface 253, the connecting surface 252, and the engaging surface 251 successively cross the engaging groove 111 in the axial direction. The upper side of the engaging surface 251 abuts against the engaging groove 111, thereby limiting the fixing member 200 from axially upwardly disengaging from the mounting hole 110.
