Referring to fig. 1 to 6, the electric lamp of the present embodiment includes a lamp body 100, a heat sink 200, and a light source board 300, where the light source board 300 is installed on an installation board 210 of the heat sink 200, and a plurality of light sources are installed on the light source board 300, and the light sources are powered on to emit light, in the present embodiment, the light sources may adopt LED lamp beads;

the heat sink 200 is installed in the lamp body 100, and an end of the lamp body 100 where the heat sink 200 is installed is open, and the open end is hermetically assembled and fixed with the lamp cover 400. When the LED lamp is used, the light source board emits light, and light rays penetrate through the lamp body and the lampshade to be ejected out for illumination.

The lamp body 100 is further provided with a lamp holder 110, the lamp holder 110 is fixed with an installation column 120, the installation column 120 is provided with a clamping groove 121, a plastic ring 500 is sleeved outside the installation column 120, the plastic ring 500 is provided with a ring body 530, the ring body 530 is respectively fixed with a first elastic plate 510 and a second elastic plate 520, the first elastic plate 510 and the second elastic plate 520 are distributed on the circumference direction of the ring body 530 at intervals, a through groove 501 is arranged between the first elastic plate 510 and the second elastic plate 520, a clamping protrusion 511 is arranged on the inner side of the first elastic plate 510 and is clamped and assembled with the clamping groove 121, the first elastic plate 510 and the second elastic plate 520 have elasticity, the inner sides of the first elastic plate 510 and the second elastic plate 520 are conical surfaces 502, and the diameters of the conical surfaces 502 are gradually increased from the open ends of the first elastic plate 510 and the second elastic plate 520 to the end 530 of the ring body. The connection between the ring body 530 and the first elastic plate 510 and the connection between the ring body 530 and the second elastic plate 520 are provided with a buffer groove 531, the buffer groove 531 is tightly attached to the limit ring 122, and the limit ring 122 is fixed on the mounting post 120. During use, the buffer groove 531 is attached to the limit ring 122, so that the plastic ring 500 is axially limited.

The outside cover of plastic ring 500 is equipped with lamp socket 600, and the chucking is on plastic ring 500 through the tight technology of machine cramping on lamp socket 600 to realize the stable assembly between lamp socket 600 and the lamp body, and the bump that the lamp socket formed can not direct action on the lamp body, thereby prevents that the lamp body from being damaged.

The open ends of the first elastic plate 510 and the second elastic plate 520 are respectively provided with a first protrusion 512 and a second protrusion 521, the outer wall of the lamp holder is provided with a thread 621, the inner wall of the lamp holder 600 and the corresponding part of the thread 621 are provided with a thread groove 622, and the first protrusion 512 and the second protrusion 521 are respectively assembled with the thread groove 622 in a clamping manner, so that the assembly strength between the lamp holder and the plastic ring is higher.

The end, far away from the lamp body 100, of the lamp socket 600 is provided with a wiring head 610, the wiring head 610 is provided with a wiring hole 602, the wiring hole 602 penetrates through the lamp socket 600, and when the lamp socket is used, an electrode penetrates out of the wiring hole 602 or is arranged in the wiring hole 602. The socket 600 and the electrode are respectively connected with the power-in end and the power-out end of the light source in a conductive manner, so that the light source can be electrified to emit light when the socket 600 and the electrode are electrified.

After the plastic ring 500 is sleeved on the mounting post 120, the open ends of the first elastic plate 510 and the second elastic plate 520 are opened towards the direction far away from the axial direction of the plastic ring 500 due to the effect of the mounting post, so that after the lamp holder 600 is sleeved outside the plastic ring 500, the first elastic plate 510 and the second elastic plate 520 are respectively pressed against the inner wall of the lamp holder 600 to relatively clamp the lamp holder 600.

Preferably, the outer walls of the first elastic plate 510 and the second elastic plate 520 are further provided with external threads 540, respectively, and the external threads 540 can be screwed with internal threads formed by the thread grooves 622, so as to fix the lamp socket 600 on the first elastic plate 510 and the second elastic plate 520. This summation can avoid glue brushing or machine banding, thereby reducing manufacturing costs and simplifying assembly processes. However, this method is prone to cause the lamp socket and the plastic ring to fall off after the lamp is installed, when the lamp needs to be disassembled and the lamp body is rotated, thereby causing a failure. In this regard, the applicant provides the second elastic plate 520 with a snap strip 550, the open end of the snap strip 550 is provided with a snap head 551, the snap strip 550 has elasticity, and the snap head 551 is not located in the wire connecting hole 602 in the initial state and the projection of the snap strip 550 in the axial direction of the wire connecting hole 602. This allows the snap strip 550 to be elastically deformed when the snap head 551 is fitted into the wire connection hole 602, so that the snap strip 550 drives the snap head 551 to be chucked with the outside of the wire connection hole 602 by the elastic force when the snap head 551 passes through the wire connection hole 602. This makes the plastic ring and the socket axially restricted by the snap-fit head 551 and the stop ring 122, respectively, so that the plastic ring and the socket are axially fixed relative to each other. When the electric lamp is disassembled, even if the screwing direction of the external thread 540 is the same as that of the thread 621, the first elastic plate 510 and the second elastic plate 520 clamp the lamp socket 600, and the buckling head 551 and the limiting ring 122 axially limit the lamp socket, so that the lamp socket 600 cannot be separated from the plastic ring, and normal disassembly and assembly are not influenced.

The details of the present invention are well known to those skilled in the art.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
