[0036] Please also read Figures 1 to 3, the ceiling lamp provided by the embodiment of the present application will be described. The ceiling lamp includes a lamp cover 10, a chassis 20, a plurality of card holders 30 and elastic pieces 40. The lamp cover 10 is generally circular. The outer peripheral edge of the lamp cover 10 extends inward and then extends upward to form an annular wall. The annular wall is recessed inward to form a plurality of bosses 11 spaced circumferentially. The cross-section of the boss 11 is triangular, and the corner of the boss 11 close to the central axis of the lamp cover 10 is smoothly transitioned. Three sponge pads 50 are circumferentially spaced on the upper part of the chassis 20 to ensure that when the lamp body is installed on the ceiling, it can be mutually pressed with the ceiling and ensure the balance and stability of the lamp body, so that the lamp body is not easily loosened after installation.

[0037] A power supply adapter box 60, a lamp board 70 and a light guide cover 80 are also provided on the chassis 20. The power supply adapter box 60 is used to transfer the commercial power. A plurality of lamp beads are provided on the lamp board 70, and the lamp board 70 is electrically connected to the power supply adapter box 60 through a wiring terminal. The light guide cover 80 is arranged above the lamp board 70. The card holder 30 can be an injection molded part. The number of the card holders 30 is the same as the number of the bosses 11 on the lamp cover 10, and the positions of the card holders 30 and the bosses 11 are arranged in one-to-one correspondence.

[0038] Refer to Figures 3 to 6 , the card holder 30 has opposite first and second sides. A receiving cavity 301 adapted for the boss 11 to be inserted is provided on the first side of the card holder 30, and the boss 11 is inserted into the receiving cavity 301. At least two buckles 31 are spaced on the top surface of the card holder 30, and a protrusion 32 is provided on the bottom surface of the buckle 31. The chassis 20 is circumferentially spaced with through holes 21 adapted for the buckles 31 and positioning holes 22 adapted for the protrusions 32, that is, the through holes 21 and the positioning holes 22 of the chassis 20 are arranged in pairs, the positioning holes 22 are located beside the through holes 21, and the number of the through holes 21 is equal to the number of the card holders 30. Align the entrance of the receiving cavity 301 of the card holder 30 with the boss 11 of the lamp cover 10, so that the boss 11 is inserted into the receiving cavity 301 to complete the installation of each card holder 30 on the lamp cover 10. Then align the buckle 31 of the card holder 30 with the corresponding through hole 21 of the chassis 20, and then rotate the lamp cover 10 by a predetermined angle in the first direction, so that the protrusion 32 on the buckle 31 is inserted into the positioning hole 22 of the chassis 20, and the buckle 31 is buckled with the chassis 20 to realize the rotational snap connection installation between the card holder 30 and the chassis 20.

[0039] Refer to Figure 2 、 Figures 6 to 8, at least one card seat 30 is provided with a spring piece 40. The spring piece 40 can be made of, but is not limited to, a metal material. The spring piece 40 includes a plugging portion 42 and an elastic arm 41. A through hole 302 is formed in the card seat 30, and the through hole 302 extends from the second side of the card seat 30 to the bottom surface, so that an entrance for the elastic arm 41 of the spring piece 40 to extend into the accommodating cavity 301 is formed on the card seat 30. A clamping groove 34 is provided on the second side of the card seat 30, and the plugging portion 42 of the spring piece 40 is clamped in the clamping groove 34. In this embodiment, three card seats 30 are provided, and a spring piece 40 is installed on one of the card seats 30. Through the entrance formed in the card seat 30, the spring piece 40 is pressed into the card seat 30. When the elastic arm 41 of the spring piece 40 extends into the accommodating cavity 301, the plugging portion 42 elastically deforms during the process of being inserted into the clamping groove 34 and is elastically clamped in the clamping groove 34, so that the spring piece 40 is installed on the card seat 30. The arrangement of the elastic arm 41 can prevent the boss 11 from easily sliding out of the accommodating cavity 301. When the lamp shade 10 needs to be removed, the lamp shade 10 can be rotated in the reverse direction, so that the boss 11 slides past the elastic arm 41 until the boss 11 completely disengages from the accommodating cavity 301, thus realizing the disassembly of the lamp shade 10. The installation of the card seat 30 and the spring piece 40 does not require screwing, which can achieve rapid installation on the production line, and the overall appearance of the product is relatively simple after assembly.

[0040] Compared with the prior art, for the ceiling lamp provided by this application, a spring piece 40 is installed on the card seat 30, and a boss 11 is provided on the lamp shade 10. When the boss 11 is snapped into the accommodating cavity 301 of the card seat 30, it first crosses the elastic arm 41 of the spring piece 40, and the elastic arm 41 resets and straightens again, so that the boss 11 is relatively fixed in the card seat 30; the through hole 302 on the card seat 30 extends to the bottom surface, making it easier for the elastic arm 41 of the spring piece 40 to extend into the accommodating cavity 301 of the card seat 30, and the plugging portion 42 of the spring piece 40 is installed in the clamping groove 34 of the card seat 30; a protrusion 32 is provided on the buckle 31 of the card seat 30. In this way, the buckle 31 passes through the through hole 21 of the chassis 20, and the protrusion 32 on the buckle 31 can be buckled with the positioning hole 22 of the chassis 20 after the card seat 30 rotates, thereby realizing the rotary snap-in installation between the card seat 30 and the chassis 20. The installation operation is simple, screw-free installation is achieved, and the product assembly efficiency is improved.

[0041] Refer to Figures 7 to 9The side wall of the second side of the card holder 30 extends to form a bottom plate 340 and two opposite side plates 343. The bottom plate 340 is connected between the two side plates 343. The bottom surface of the bottom plate 340 is vertically spaced with a first clamping plate 341 and a second clamping plate 342. The two side plates 343, the bottom plate 340, the first clamping plate 341, the second clamping plate 342 and the card holder 30 form a clamping groove 34. The spring piece 40 also includes a first abutting portion 43 and a second abutting portion 44 for further fixing the plug-in portion 42. The plug-in portion 42 abuts against the second clamping plate 342, and the second abutting portion 44 abuts against the side wall of the second side of the card holder 30. An installation groove 344 is formed between the side plate 343 of the two side plates 343 close to the through hole 302 and the first clamping plate 341 , and the first abutting portion 43 is installed in the installation groove 344 , so that a part of the spring sheet 40 can be elastically clamped and fixed in the clamping groove 34 .

[0042] A first bending portion 45 and a second bending portion 46 are provided between the elastic arm 41 and the plug-in portion 42. The first bending portion 45 is connected between the elastic arm 41 and the first abutting portion 43, and the second bending portion 46 is connected between the first abutting portion 43 and the plug-in portion 42. The connection between the first bending portion 45 and the elastic arm 41 and the first abutting portion 43 is a right angle, and the elastic arm 41, the first bending portion 45 and the first abutting portion 43 form a U-shaped bend; the second bending portion 46 and the first abutting portion 43 form a roughly V-shaped bend. The connection between the second bending portion 46 and the first abutting portion 43 is an acute angle, and the connection between the first abutting portion 43 and the plug-in portion 42, and the connection between the plug-in portion 42 and the second abutting portion 44 are both obtuse angles. The height of the first clamping plate 341 is set to be less than half the height of the second clamping plate 342, so that the part between the plug-in portion 42 and the first bending portion 45 is easily inserted into the clamping groove 34.

[0043] A bending section 440 is provided at the end of the second abutting portion 44 , and the bending section 440 is connected to the second abutting portion 44 at an obtuse angle. The second abutting portion 44 abuts against the holder 30 via the bending section 440 , so that the contact area between the second abutting portion 44 and the side wall of the holder 30 is small.

[0044] An escape groove 35 is provided on the side wall of the second side of the holder 30 at a position corresponding to the second clamping plate 342 , so that more escape space is formed in the clamping groove 34 , which facilitates the operation of inserting the plug-in portion 42 into the clamping groove 34 .

[0045] Two undercuts 3420 are spaced apart on one side of the second clamping plate 342 facing the clamping seat 30 , so as to prevent the inserting portion 42 of the spring sheet 40 from sliding out of the clamping slot 34 .

[0046] A notch 3421 is provided in the portion of the second clamping plate 342 between the two reverse buckles 3420. When the elastic piece 40 needs to be removed from the card seat 30, a force can be applied to the clamping groove 34 from the notch 3421 of the second clamping plate 342, so that the insertion portion 42 is disengaged from the two reverse buckles 3420, and then the elastic piece 40 can be removed from the card seat 30 as a whole.

[0047] Refer to Figure 6 and Figure 9 , a rib 33 is convexly provided on the bottom surface of the buckle 31. The thickness of the rib 33 is set to be less than the thickness of the protrusion 32. The length direction of the rib 33 is set to be parallel to the width direction of the buckle 31, and the rib 33 abuts against the chassis 20. The provision of the rib 33 can increase the overall structural strength of the buckle 31 and reduce the deformation of the buckle 31.

[0048] Please refer to Figure 1 , Figure 5 , Figure 6 and Figure 10 , a groove 36 is provided on the top surface of the card seat 30 corresponding to the position of the buckle 31. In this way, the distance between the buckle 31 and the card seat 30 is increased, which is convenient for the operation when the card seat 30 is rotated and snapped into the chassis 20, and is more labor-saving. A strip hole 37 is provided at the bottom of the groove 36 corresponding to the position of the protrusion 32, and one side of the strip hole 37 has a notch. The buckle 31 has a reduced-diameter section, and the width of the reduced-diameter section gradually decreases from one end to the other end, and the end of the other end with a smaller width is set to have a smooth transition, so that the buckle 31 can more easily pass through the corresponding through hole 21 of the chassis 20.

[0049] A first guiding inclined surface 321 for facilitating the engagement of the protrusion 32 into the positioning hole 22 is provided on the bottom surface of the protrusion 32. By providing the first guiding inclined surface 321, the operation of rotating and snapping the card seat 30 into the chassis 20 is made smoother.

[0050] Refer to Figure 2 , Figure 6 , a second guiding inclined surface 38 is provided on the bottom surface of the card seat 30 at the entrance end of the accommodating cavity 301. In this way, it plays a guiding role and can also make the size of the entrance of the accommodating cavity 301 larger, which is convenient for the operation of sliding the boss 11 into the card seat 30.

[0051] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
