[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example

[0026] See Figures 1 to 3 As shown, an easy-to-assemble LED bulb lamp includes a lamp body 1 and a bulb shell 2. A light source board 3 and a driving circuit board 4 are fixed in the lamp body, and the driving circuit board is electrically connected to the light source board. In this embodiment, the lamp body is a plastic structure, and the bulb shell is a translucent plastic structure or an acrylic structure. The light source board and the driving circuit board are both conventional structures in the prior art, so they are not described in detail and are simply applied.

[0027] In this embodiment, several mounting brackets 5 are provided on the outer wall of the lamp body. Both the mounting brackets and the bulb are made of translucent plastic or acrylic structures. A strip groove 6 is provided on the inner side of the mounting bracket. An arcuate plate 7 is disposed within the strip groove, the center of which is rotatably connected to the strip groove via a pin 8. The arcuate plate is a metal or ceramic plate. Furthermore, a pressing hole 9 is provided on the upper portion of the mounting bracket to mate with the strip groove. In actual use, a pressing boss 10 is provided on the upper outer wall of the arcuate plate, a hook 11 is provided on the lower inner wall of the arcuate plate, and a return spring 12 is fixed between the arcuate plate and the inner wall of the strip groove. Furthermore, the pressing boss passes through the pressing hole and extends out of the outer side of the mounting bracket. The pressing boss can be pressed to rotate the arcuate plate about the pin and to engage or disengage the hook with the raised ring.

[0028] In actual use, a raised ring 13 is integrally formed on the outer wall of the bulb. During installation, the bulb is connected to the lamp body, and the arc-shaped piece, under the action of a return spring, causes the hook to hook onto the raised ring and position it. The hook and the raised ring enable the bulb to be connected and positioned with the lamp body, and also facilitate assembly and disassembly operations.

[0029] In actual use, the number of mounting support plates is three or four; the outer surface of the convex ring is attached to the inner surface of the mounting support plate to prevent deviation and limit position. This structure can prevent the upper bulb from deflecting or shifting after installation, ensuring smooth and reliable installation.

[0030] In actual use, to improve waterproof performance, a sealing ring 14 is provided at the contact point between the bulb and the lamp body. A lamp cap 15 is fixed to the lamp body. The lamp cap is mainly used to connect to the lamp holder, and the sealing ring can prevent water from entering through the connection, improving waterproof sealing.

[0031] The utility model has positive effects: the structure of the utility model is reasonably set up, and the mounting support plate is set on the lamp body, which cooperates with the arc-shaped piece, the reset spring and the pressing convex column. When the bulb shell is installed, the arc-shaped piece is used to snap the hook onto the convex ring of the bulb shell for positioning under the action of the reset spring, which improves the convenience of installation and can also ensure the stability of installation. At the same time, when disassembling, it is only necessary to press the convex column to rotate the arc-shaped piece around the pin shaft, and to separate the hook from the convex ring, and then the bulb shell can be disassembled, which improves the convenience of disassembly, is stable and reliable to use, and has strong applicability and good practicality.

[0032] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0033] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
