[0040] Example

[0041] Please refer to Figure 1-Figure 7 As shown, the present embodiment provides a light bulb structure that is easy to assemble, including a lampshade 10, a lamp holder 11 and an aluminum substrate 12. The lower end of the lampshade 10 is indented inward to form a joint portion 101, and the joint portion 101 can be inserted into the lamp holder 11, and a plurality of bayonet holes 1011 are provided through the joint portion 101 in the thickness direction. A plurality of protrusions 111 that are engaged with the bayonet holes 1011 are provided on the upper end of the inner side surface of the lamp holder 11, and the bayonet holes 1011 are engaged with the protrusions 111 so that the lamp can be assembled. The cover 10 is assembled on the lamp holder 11, and the width of the bayonet 1011 is greater than the width of the protrusion 111, so that the protrusion 111 can pass through the bayonet 1011 more smoothly to achieve the snap-fit, thereby reducing the accuracy requirement for the alignment of the bayonet 1011 and the protrusion 111 during assembly. While satisfying the snap-fit ​​between the bayonet 1011 and the protrusion 111, the assembly difficulty of the lamp cover 10 and the lamp holder 11 is reduced, which facilitates mechanical automated production, can effectively improve assembly efficiency, and has good practicality.

[0042] Furthermore, since the bayonet 1011 is arranged to penetrate the joint part 101 in the thickness direction, the thickness of the protruding portion of the protrusion 111 can be increased according to actual needs, thereby increasing the stability of the connection between the bayonet 1011 and the protrusion 111. By adopting the through-type design of the bayonet 1011, the light bulb can meet the drop test requirements, and the lampshade 10 and the lamp holder 11 will not separate during the drop test.

[0043] In order to further ensure the stability of the connection between the lampshade 10 and the lamp holder 11, a plurality of first insert teeth 1012 are circumferentially spaced apart on the upper edge of the outer side surface of the splicing portion 101, and a plurality of second insert teeth 112 engaged with the first insert teeth 1012 are circumferentially spaced apart on the upper end of the inner side surface of the lamp holder 11. The first insert teeth 1012 and the second insert teeth 112 are alternately arranged in corresponding empty spaces, that is, there is an empty space between two adjacent first insert teeth 1012 for the second insert teeth 112 to be inserted. Similarly, there is an empty space between two adjacent second insert teeth 112 for the first insert teeth 1012 to be inserted. The first insert teeth 1012 and the second insert teeth 112 are alternately engaged to limit the rotation of the lampshade 10 relative to the lamp holder 11, thereby improving the stability of the connection between the lampshade 10 and the lamp holder 11.

[0044] In addition, a plurality of clamping blocks 113 for clamping the aluminum substrate 12 are arranged at equal intervals along the circumferential direction on the inner side surface of the lamp holder 11. The aluminum substrate 12 can be clamped on the clamping blocks 113 by pressing the aluminum substrate 12 toward the inside of the lamp holder 11. The spacing between the clamping blocks 113 can be adaptively adjusted according to the size of the aluminum substrate 12. Since the plurality of clamping blocks 113 are arranged at equal intervals along the circumferential direction, the aluminum substrate 12 can be rotated on the horizontal plane and pressed into the lamp holder 11 at any angle. Both opposite sides of the aluminum substrate 12 can be clamped by the clamping blocks 113, and there is no need to adjust the position of the aluminum substrate 12 to align with the clamping blocks 113, which reduces the difficulty of assembling the aluminum substrate 12 to adapt to mechanical automated production and improve assembly efficiency. Moreover, both opposite sides of the aluminum substrate 12 are clamped by the clamping blocks 113 to ensure the stability of the connection between the aluminum substrate 12 and the lamp holder 11.

[0045] like Figure 2 and Figure 5 As shown, in this embodiment, the clamping block 113 includes a first clamping portion 1131 and a second clamping portion 1132, the lower end of the first clamping portion 1131 is recessed to form a clamping groove 11312 for clamping the aluminum substrate 12, and the upper end of the second clamping portion 1132 extends toward the center of the lamp holder 11 to form a supporting surface 11321 for supporting the aluminum substrate 12.

[0046] Specifically, the first clamping portion 1131 and the second clamping portion 1132 are protruding relative to the clamping groove 11312, and the clamping groove 11312 is located between the first clamping portion 1131 and the second clamping portion 1132. When assembling the aluminum substrate 12, pressing the aluminum substrate 12 toward the lamp holder 11 can make the aluminum substrate 12 be clamped in the clamping groove 11312 by the first clamping portion 1131 and the second clamping portion 1132. The first clamping portion 1131 and the second clamping portion 1132 limit the vertical displacement of the aluminum substrate 12, so that the aluminum substrate 12 is firmly installed in the lamp holder 11, and the supporting surface 11321 increases the contact area between the aluminum substrate 12 and the second clamping portion 1132, thereby supporting the aluminum substrate 12 and further strengthening the stability of the connection between the aluminum substrate 12 and the lamp holder 11.

[0047] like Figure 7 As shown, in this embodiment, since the clamping blocks 113 are distributed circumferentially along the inner side surface of the lamp holder 11, the aluminum substrate 12 is set to be a waist-shaped plate composed of two long sides and two short sides, the long sides are a straight line structure, the short sides are an arc structure with the same arc as the lamp holder 11 and the center of the circle, and the length of the aluminum substrate 12 is the same as the circumferential diameter formed by the multiple clamping grooves 11312, so that the aluminum substrate 12 can be clamped by the clamping blocks 113 when it is pressed toward the inside of the lamp holder 11.

[0048] Furthermore, the distance between any two adjacent clamping blocks 113 is smaller than the width of the aluminum substrate 12, so that the aluminum substrate 12 can be rotated on the horizontal plane and pressed into the lamp holder 11 at any angle, and its two short sides can be clamped by at least one clamping block 113 to ensure the stability of the aluminum substrate 12 assembled in the lamp holder 11.

[0049] like Figure 2 and Figure 5 As shown, in this embodiment, the upper end of the first clamping portion 1131 is provided with a guiding arc surface 11311, which can guide the action of pressing the aluminum substrate 12 into the clamping groove 11312, thereby allowing the aluminum substrate 12 to smoothly enter the clamping groove 11312 and be clamped.

[0050] like Figure 2 and Figure 6 As shown, in this embodiment, the upper end of the protrusion 111 is provided with a guiding inclined surface 1111, which can guide the movement of the joint portion 101 of the lampshade 10 extending into the lamp holder 11. Since the bayonet 1011 is arranged through the joint portion 101 along the thickness direction, the bayonet 1011 and the protrusion 111 can be smoothly buckled.

[0051] like Figure 2 As shown, in this embodiment, a weight-reducing groove 1112 is provided on the protrusion 111 to reduce the overall weight of the bulb, making it easier to carry, transport, and disassemble.

[0052] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, a lamp holder 114 is provided at the lower end of the lamp holder 11. The lamp holder 114 is an interface for installing the light bulb, and can be a bayonet type lamp holder or a screw type lamp holder. The light bulb is connected to electricity through the lamp holder 114 to play the role of light illumination.

[0053] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
