[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] See also Figures 1 to 3 As shown, the utility model discloses a lamp, including a lamp housing 1 and a diffuser plate 2 detachably connected to the lamp housing 1, an assembly cavity 10 is provided at the bottom of the lamp housing 1, the diffuser plate 2 is assembled in the assembly cavity 10, and the lamp housing 1 and the diffuser plate 2 are connected by a snap-fit ​​structure 3.

[0026] The buckle structure 3 includes a limiter 31 and a clamping member 32, wherein the limiter 31 is disposed at opposite sides of the lamp housing 1, and the clamping member 32 is correspondingly disposed at the end of the diffuser plate 2. Preferably, the limiter 31 is integrally formed with the lamp housing 1, and the clamping member 32 is integrally formed with the diffuser plate 2. Of course, in other embodiments, the limiter 31 and the clamping member 32 may be independent components, which is not limited thereto.

[0027] Specifically, the limiting member 31 includes an extension arm 311 and a first extension portion 312 and a second extension portion 313 extending from one side of the extension arm 311 and spaced apart from each other. A first limiting portion 3121 is provided at the end of the first extension portion 312, and a second limiting portion 3131 protruding toward the first extension portion 312 is correspondingly provided at the end of the second extension portion 313. A first accommodating cavity 31210 is recessed in the first limiting portion 3121, and a second accommodating cavity 31310 is formed between the first extension portion 312 and the second limiting portion 3131. The first accommodating cavity 31210 is connected to the second accommodating cavity 31310, and a recessed direction of the first accommodating cavity 31210 is perpendicular to a recessed direction of the second accommodating cavity 31310. The clamping member 32 is at least partially accommodated in the second accommodating cavity 31310, and is respectively squeezed in different directions by the first limiting portion 3121 and the second limiting portion 3131, so that the clamping member 32 is fixedly connected to the limiting member 31.

[0028] That is to say, by setting the first limiting portion 3121 at the end of the first extension portion 312, the corresponding portion 3121 is provided at the end of the second extension portion 313 and the second limiting portion 3131 protrudes toward the first extension portion 312, so that the first accommodating cavity 31210 recessed in the first limiting portion 3121 is connected to the second accommodating cavity 31310 formed between the first extension portion 312 and the second limiting portion 3131, so as to accommodate and clamp the clamping member 32.

[0029] In this embodiment, the clamping member 32 is arranged in a V shape and is arranged perpendicular to the diffuser plate 2. The clamping member 32 and the stopper 31 cooperate with each other to enable the diffuser plate 2 to be clamped with the lamp housing 1. At this time, the clamping member 32 is accommodated in the first accommodating cavity 31210 and the second accommodating cavity 31310 at the same time.

[0030] Optionally, in other embodiments, the clip 32 and the diffuser 2 extend along the same plane, so that the diffuser 2 is a flat plate structure, and is inserted into the second accommodating cavity 31310 fixed between the first extension portion 312 and the second limiting portion 3131. In other words, the clip structure 3 of the utility model can be adapted to diffusers 2 of various forms.

[0031] The vertical distance between the end of the first limiting portion 3121 away from the extension arm 311 and the extension arm 311 is greater than the vertical distance between the second limiting portion 3131 and the extension arm 311, so that the first limiting portion 3121 and the second limiting portion 3131 are mutually offset in both the vertical direction and the horizontal direction. In this way, the limiting member 31 can squeeze and clamp the clamping member 32 in different directions, and finally realize the clamping connection between the lamp housing 1 and the diffuser plate 2.

[0032] Specifically, the end of the clamping member 32 is provided with an extension arm 321 and a clamping portion 322 formed at the end of the extension arm 321, the clamping portion 322 is V-shaped, and has a first clamping arm 3221 and a second clamping arm 3222 extending outward from the extension arm 321, when the clamping member 32 and the limiting member 31 are clamped, the first clamping arm 3221 is accommodated in the second accommodating cavity 31310 and abuts against the second limiting portion 3131, and the end of the second clamping arm 3222 is accommodated in the first accommodating cavity 31210 and abuts against the first limiting portion 3121.

[0033] Preferably, the clamping portion 322 is specifically in two shapes of “<”, “>” to cooperate with the limiting member 31 for clamping.

[0034] A third limiting portion 3122 is further provided at the connection between the first limiting portion 3121 and the first extending portion 312. When the clamping member 32 and the limiting member 31 are clamped, the second clamping arm 3222 abuts against the first limiting portion 3121 and the third limiting portion 3122 at the same time. In this way, the diffusion plate 2 is firmly clamped on the lamp housing 1 by the limiting and squeezing of the first limiting portion 3121, the second limiting portion 3131 and the third limiting portion 3122 in different directions.

[0035] It is defined that the first clamping arm 3221 has a first positioning point 3223 abutting against the second limiting portion 3131, the second clamping arm 3222 has a second positioning point 3224 abutting against the third limiting portion 3122, the end of the second clamping arm 3222 is the third positioning point 3225, the first positioning point 3223 is close to the extension arm 321, and the second positioning point 3224 is close to the connection point between the first clamping arm 3221 and the second clamping arm 3222.

[0036] Preferably, the second limiting portion 3131 is in contact with the extension arm 321, so that the first positioning point 3223 is close to the extension arm 321. In this way, the connection between the diffuser plate 2 and the lamp housing 1 is more stable.

[0037] Please combine Figure 4 and Figure 5 As shown, when the diffuser plate 2 is installed, the connection between the clamping member 32 and the limiting member 31 prevents the diffuser plate 2 from falling off due to forced squeezing; moreover, when the diffuser plate 2 tends to fall off downward after long-term use, the diffuser plate 2 is always clamped on the lamp housing 1 due to the existence of the limiting member 31 and will not fall off downward, thereby enhancing the connection stability between the lamp housing 1 and the diffuser plate 2 and extending the service life of the lamp.

[0038] In summary, the buckle structure 3 and the lamp of the utility model are configured with a first limiting portion 3121 at the end of the first extension portion 312, and a second limiting portion 3131 protruding toward the first extension portion 312 at the end of the second extension portion 313, so that the first accommodating cavity 31210 recessed in the first limiting portion 3121 is connected to the second accommodating cavity 31310 formed between the first extension portion 312 and the second limiting portion 3131, thereby being adaptable to different clips 32 and improving the applicability.

[0039] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
