Referring to fig. 1 to 3, the ceiling lamp 10 includes: a lamp body structure; a light source module 11 located in the lamp body structure.

The lamp body structure includes: chassis 100 and mask 200.

The chassis 100 is circumferentially provided with a chassis flange 110, a plurality of first limiting parts 120 are formed on the inner side wall of the chassis flange 110 at intervals, and a gap 130 is formed between the first limiting parts 120 and the chassis 100.

The mask 200 includes: a mask body 210 and an annular second stop 220.

The second limiting portion 220 is formed on the peripheral edge of the mask body 210, a plurality of yielding notches 230 corresponding to the plurality of first limiting portions 120 are formed on the second limiting portion 220, and the yielding notches 230 are adapted to the first limiting portions 120.

The second limiting portion 220 is configured to yield the plurality of first limiting portions 120 through the plurality of yielding notches 230 so as to rotationally clamp into the gap 130, the first limiting portions 120 can limit the second limiting portions 220 in the rotation direction of the second limiting portion 220, and when the second limiting portions 220 are limited by the first limiting portions 120, the yielding notches 230 are dislocated with the first limiting portions 120.

Because annular second spacing portion 220 is put away a plurality of first spacing portions 120 through a plurality of breach of stepping down 230 to rotatory card income clearance 130, in the direction of rotation of second spacing portion 220, first spacing portion 120 can spacing second spacing portion 220, and, when second spacing portion 220 is spacing by first spacing portion 120, breach of stepping down 230 dislocation with first spacing portion 120, consequently, mask main part 210 is difficult for the deformation, and, the simple structure of whole lamp body structure, with low costs, simultaneously, when being spacing by first spacing portion 120 through annular second spacing portion 220, breach of stepping down 230 misplaces with first spacing portion 120, effectively reduced the space that the mosquito can get into in the lamp body structure, have better anti-mosquito effect. In addition, since the first limiting portion 120 can limit the second limiting portion 220 in the rotation direction of the second limiting portion 220, and accordingly, the rotation of the mask 200 is stopped, it is easy for the operator to determine whether the mask 200 and the chassis 100 are connected in place or not.

In some embodiments, the gap 130 includes at least two gap widths of different sizes, and one of the two gap widths is used to rotationally clamp the second limiting portion 220 into the gap 130, and the other of the two gap widths is used to abut the second limiting portion 220 with the adjacent first limiting portion 120 in the rotational direction thereof to be limited by the first limiting portion 120.

Note that the gap width of the gap 130 means: the gap 130 is proximate to the spacing between the bottom surface of the chassis 100 and the chassis 100.

Specifically, in some embodiments, the first limiting portion 120 is a limiting strip protruding relative to the inner sidewall of the chassis flange 110, and a distance between one end of the limiting strip and the chassis 100 is smaller than a distance between the other end of the limiting strip and the chassis 100. Further, the limiting bar is disposed obliquely with respect to the chassis 100, so that the gap width of the gap 130 gradually changes along the rotation direction of the second limiting portion 220.

In some embodiments, the number of the first limiting portions 120 is plural, and the first limiting portions 120 are uniformly distributed around the chassis 100. Thus, the reliability of the connection of the chassis 100 and the mask 200 is more advantageously improved.

In some embodiments, the second stopper 220 includes: a first flange 221, a second flange 222 and a third flange 223.

The first flange 221 extends from the peripheral edge of the mask body (210) toward the center of the mask body 210, the second flange 222 extends from the first flange 221 toward the chassis 100, the third flange 223 extends from the second flange 222 toward the center of the mask body 210, the first flange 221, the second flange 222 and the third flange 223 jointly enclose an annular relief groove 224 that is open toward the first limiting portion 120, and the annular relief groove 224 is sized to fit the first limiting portion 120. When the second limiting portion 220 is clamped into the gap 130, a part of the third flange 223 is located in the gap 130, and the first limiting portion 120 is located in the annular yielding groove 224.

In some embodiments, a plurality of raised third limiting portions 240 are formed at the bottom of the annular relief groove 224, the plurality of third limiting portions 240 are disposed at intervals, and the third limiting portions 240 are offset from the relief notch 230. When the second limiting portion 220 is limited by the first limiting portion 120, the third limiting portion 240 is also limited by the first limiting portion 120. Through a plurality of third spacing portions 240, can cooperate the second spacing portion 220 to realize dual spacing, ensure the connection reliability of face guard 200 and chassis 100 better.

Specifically, in the extending direction of the second flange 222, the height of the third limiting portion 240 is greater than the thickness of the third flange 223, so that the third limiting portion 240 can be limited at a larger gap width than the third flange 223 in the gap 130.

In some embodiments, the third limiting portion 240 may be clamped in the gap 130 by interference through micro-deformation of the third limiting portion 240 and the gap 130, so as to further increase the connection reliability between the mask 200 and the chassis 100. It should be understood that since micro deformation occurs in the third limiting portion 240, deformation influence is not generated to the mask body 210.

In some embodiments, the number of the third limiting portions 240 is plural, and the plurality of third limiting portions 240 are uniformly distributed around the chassis 100. Thus, the reliability of the connection of the chassis 100 and the mask 200 is more advantageously improved.
