Description

[0001] The utility model relates to the technical field of ball light bulbs, in particular to a glue-free light bulb. Background Art

[0002] In the design and manufacturing process of existing bulb lamps, the assembly method between the bulb and the lampshade is usually a combination of snap-fit ​​and glue. However, this method has caused a series of problems.

[0003] First of all, the gluing process not only increases the manpower and material costs in production, but also puts a burden on the environment. In addition, during the gluing process, glue is prone to overflow or contaminate the surface of the bulb, which not only affects the appearance of the product, but may also cause quality problems during the use of the lamp, thereby reducing the product's pass rate.

[0004] Secondly, the existing pure buckle assembly method fails to effectively solve the problem of fixing the bulb and the lampshade. Due to the limitations of the buckle design, the bulb is prone to rotation during use, which not only affects the stability of the lamp, but also may cause the directionality of the light source and the lighting effect to be damaged, thus affecting the user experience.

[0005] In addition, in existing bulbs, the aluminum substrate is mainly fixed by screws, which is a traditional method that is particularly cumbersome during assembly. The use of screws not only increases assembly time and production steps, but also easily causes material loss or damage during disassembly and replacement, which brings inconvenience to maintenance.

[0006] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present invention is made based on this situation. Utility Model Content

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figures 1 to 3 As shown, this embodiment provides a glue-free light bulb, which specifically includes a light bulb shell 1, a lampshade 2, a lamp cap 3 (usually a threaded cap) disposed at the upper end of the lampshade 2, and a substrate 4 (usually an aluminum substrate) disposed inside the lampshade 2. The substrate 4 is usually provided with a light-emitting element. In order to ensure a stable connection between the light bulb shell 1 and the lampshade 2, this embodiment designs a variety of clamping and positioning structures to improve assembly convenience and component stability.

[0027] Furthermore, the upper end of the bulb shell 1 is provided with a first annular platform 11 extending upward, and the lower end of the lampshade 2 is provided with a second annular platform 21 extending downward. A plurality of baffles 22 are provided inside the second annular platform 21, and a plug-in gap 23 is formed between the baffles 22 and the second annular platform 21, into which the first annular platform 11 can be inserted from bottom to top.

[0028] A first clamping structure is provided between the bulb shell 1 and the lampshade 2, which can quickly realize the disassembly and assembly between the two, and has the advantage of no need to apply glue. This design not only reduces the waste of manpower and material resources in the production process, but also effectively avoids quality problems caused by glue. At the same time, the design of the first clamping structure makes the replacement and maintenance of the bulb more convenient, and the user can easily operate it.

[0029] In the first clamping structure, a plurality of clamping holes 111 are provided on the first annular platform 11 , and corresponding first clamping buckles 211 are provided on the inner side wall of the second annular platform 21 . The first clamping buckles 211 can be clamped with the corresponding clamping holes 111 .

[0030] It is worth noting that the cross section of the first buckle 211 is triangular and the top is flat, which can effectively enhance the engagement strength of the buckle and reduce the risk of loosening caused by the rotation of the bulb. Such a design is also conducive to improving the structural strength of the first buckle 211 and preventing it from breaking.

[0031] In addition, in order to further improve the stability of the structure, the first buckle 211 and the baffle 22 are staggered in the circumferential direction to avoid mutual interference.

[0032] In order to solve the deviation problem that may occur during the installation process, a positioning structure is also provided in the embodiment. This structure is composed of a positioning rib plate 212 provided on the inner side wall of the second annular platform 21, and a positioning notch 112 provided on the first annular platform 11 and for the positioning rib plate 212 to be inserted. Through this design, accurate circumferential positioning can be achieved during installation, ensuring the precise matching of the bulb housing 1 and the lampshade 2, thereby improving the stability and reliability of the overall product.

[0033] The installation of the base plate 4 also adopts the glue-free process, and the second clamping structure is set to realize the quick disassembly and assembly between the lampshade 2 and the base plate 4. This structure includes a plurality of vertical ribs 24 and transverse buckles 25 arranged on the inner wall of the lampshade 2. The transverse buckles 25 are arranged on the lower side of the vertical ribs 24, and there is a certain gap between the lower end surface of the vertical ribs 24 and the top surface of the transverse buckles 25. The base plate 4 is firmly clamped in the gap between the lower end surface of the vertical ribs 24 and the transverse buckles 25. This design not only greatly improves the assembly efficiency, but also avoids the tediousness and inconvenience brought by the traditional screw fixing method.

[0034] Furthermore, the vertical ribs 24 and the transverse buckles 25 are staggered in the circumferential direction. This staggered design has several advantages:

[0035] 1) Enhanced fixing effect: By staggering the vertical ribs 24 and the horizontal buckles 25 , a more uniform force distribution can be obtained in the clamping area of ​​the base plate 4 on the inner side of the lampshade 2 .

[0036] 2) Avoid interference: The staggered layout design can ensure that the vertical ribs 24 and the horizontal buckles 25 do not interfere with each other during assembly and disassembly.

[0037] 3) Improved stability: During the use of the bulb, the heat generated by the internal light-emitting element may cause the material to expand. The staggered structure can better disperse the impact of thermal expansion in different directions, further enhancing the stability of the bulb.

[0038] The cross section of the transverse buckle 25 is triangular and the top thereof is a plane. Such a design is conducive to improving the structural strength of the transverse buckle 25 and preventing it from breaking.

[0039] In the design of the baffle 22, a chamfer 221 is provided on one side of the lower end thereof close to the second annular platform 21, which helps to provide a guiding function during the assembly process of the bulb housing 1 and the lampshade 2, ensuring that it is smoothly inserted and fixed in a predetermined position. This meticulous design improves the user's experience in actual operation and reduces the risk of incorrect installation.

[0040] In summary, the glue-free light bulb of this embodiment not only effectively improves the assembly efficiency and stability of the product through the ingenious combination of multiple clip-on and positioning structures, but also complies with the trend of environmental protection.
