Example 1

Referring to fig. 1 to 4 and 8, a ceiling lamp includes a lamp body part 1, a rear cover 2, a driving member 3, and a mounting structure 4 connecting the lamp body part 1 and the rear cover 2, the rear cover 2 being for fixing with an external mounting base such as a ceiling. The driving part 3 is fixedly mounted on the side of the rear cover 2 facing the lamp body part 1, and the rear cover 2 may be made of a cold-rolled sheet.

The lamp body part 1 comprises a lamp body 11, a lamp shade 12 and a lamp panel 13, wherein the lamp panel 13 is arranged in a containing cavity formed between the lamp body 11 and the lamp shade 12, the lamp shade 12 is positioned below the lamp body 11, the lamp shade 12 can be transparent or semitransparent, and can be formed by splicing acrylic plates, so that light rays emitted by the lamp panel 13 can be transmitted downwards through the lamp shade 12. The lamp body 11 and the lamp shade 12 can be fixed by the fastening piece 14, and the fastening piece 14 can preferably adopt a step hot-melt copper nut structure.

The mounting structure 4 connects the lamp body 11 of the lamp body part 1 and the rear cover 2. The mounting structure 4 comprises a pressing block 41, a spring piece 42 and a riveting column 43, wherein the pressing block 41 and the spring piece 42 are fixed relative to the lamp body 11, and the riveting column 43 is fixed relative to the rear cover 2. The pressing block 41 can be fixed with the lamp body 11 through two countersunk screws, and the elastic piece 42 can be fixed with the pressing block 41 through pan head screws. Referring to fig. 5 to 7, the pressing block 41 has a hollow structure, and one side facing the lamp body 11 is opened, a rotary clamping slot 411 is opened at one side far away from the lamp body 11, and the rotary clamping slot 411 penetrates through the wall thickness of the pressing block 41 at the side. The rotary catch 411 extends in an arc shape along the circumferential direction of the lamp body 11, and its opposite ends in the circumferential direction constitute an open end 4111 and a closed end 4112, respectively.

The rivet pressing column 43 includes a column 431, a neck 432 and a limiting portion 433 from top to bottom, and in this embodiment, the column 431, the top 432 and the limiting portion 433 are all cylinders, and the radial dimension of the neck 432 is smaller than that of the column 431 and the limiting portion 433. Alternatively, the post 431, the neck 432, and the stopper 433 may take other shapes as long as the projection on the mounting surface (the surface facing the rear cover 2, typically a horizontal surface in the mounted state) of the lamp body 11 is made to lie within the projection range of the post 431 and the stopper 433. The rotary latch 411 is limited in size, and the neck 432 is allowed to pass through but not the stopper 433, so that the pressing block 41 is prevented from being separated from the clinching post 43 downward, and the height of the neck 432 is greater than the height of the rotary latch 411 (the dimension in the up-down direction shown in fig. 6), so that the neck 432 has a certain degree of freedom in the up-down direction with respect to the rotary latch 411.

The pressing block 41 is formed with an opening 412 communicating with the opening end 4111 at the opening end 4111 of the rotary catch 411, whereby a space formed by the opening end 4111 and the opening 412 together can be penetrated into the pressing block 41 by the stopper 433. A limit slot 413 is formed in the pressing block 41 at a position corresponding to the closed end 4112 of the rotary slot 411, and the limit slot 413 is formed by a recess in the pressing block 41 at a position corresponding to the closed end 4112 of the rotary slot 411 toward one side of the lamp body 11 in a direction away from the lamp body 11. When the rivet pressing column 43 rotates to the closed end 4112 of the rotary clamping slot 411 relative to the pressing block 41, the limiting portion 433 of the rivet pressing column 43 can be clamped into the limiting clamping slot 413, so that the rivet pressing column 43 and the pressing block 41 are relatively fixed.

The spring plate 42 has a fixed end 421 and a free end 422, wherein the fixed end 421 is fixed at one side of the pressing block 41 near the lamp body 11, and the end corresponds to the opening end 4111 of the rotary clamping slot 411, the spring plate 42 extends at least partially inside the pressing block 41, and when installed, can be installed from the opening of the pressing block 41, and the free end 422 is far away from the lamp body 11 and near the rotary clamping slot 411 relative to the fixed end 421, the free end 422 corresponds to the closed end 4112 of the rotary clamping slot 411, and the free end 422 keeps a tendency to tilt inwards of the rotary clamping slot 411. When the rivet pressing column 43 rotates to the closed end 4112 of the rotary clamping slot 411 relative to the pressing block 41, the free end 422 of the elastic piece 42 corresponds to the limiting portion 433 of the rivet pressing column 43. Therefore, in the installation state, the limiting part 433 of the press-riveting column 43 is located in the limiting clamping groove 413, and the end part of the elastic sheet 42 can press the limiting part 433 of the press-riveting column 43 in the limiting clamping groove 413, so that the press-riveting column 43 and the pressing block 41 are prevented from rotating relatively along the circumferential direction of the lamp body 11.

When the lamp body part 1 and the rear cover 2 need to be disassembled, the lamp body part 1 is jacked up, the free end 422 of the elastic sheet 42 is pressed downwards by the riveting column 43, the elastic sheet 42 is deformed, the limiting part 433 of the riveting column 43 leaves the limiting clamping groove 413 of the pressing block 41, the riveting column 43 can rotate relative to the pressing block 41 again, so that the disassembly is completed, and the elastic sheet 42 can reset when the pressure of the riveting column 43 is not received. By the arrangement of the above-described mounting structure 4, detachment between the lamp body portion 1 and the rear cover 2 can be avoided when there is no pressing action.

Alternatively, the positions of the press block 41 (the spring piece 42) and the clinching post 43 may be interchanged. That is, one of the lamp body 11 and the rear cover 2 serves as a first mounting member, the other of the lamp body 11 and the rear cover 2 serves as a second mounting member, the pressing piece 41 (the elastic piece 42) is provided on the first mounting member, and the rear cover 2 is provided on the second mounting member.

Referring again to fig. 1 and 4, the rear cover 2 is provided with a first wire inlet 21 and a second wire inlet 22, wherein the first wire inlet 21 is provided on a top wall 23 of the rear cover 2, preferably in the middle of the top wall 23, and the second wire inlet 22 is provided on a peripheral wall 24 of the rear cover 2. Under normal conditions, the new house can reserve a power line at the position where the lamp is installed, and when the ceiling lamp is installed, the power line only needs to enter the ceiling lamp from the first wire inlet hole 21 to be connected with the driving part 3. The top wall 23 of the rear cover 2 is at least partially recessed downward to form a wire storage slot 25, and the first wire inlet hole 21 is located at the recessed portion, and can be partially folded and stored in the wire storage slot 25 when the power wire is longer.

If no power line is reserved at the lamp mounting position, an open line is needed to supply power to the ceiling lamp, and the power line from a far position enters the internal wiring of the ceiling lamp from the second wire inlet hole 22. In the case that the second wire inlet 22 is not required to be used, the second wire inlet 22 is closed by the cover plate 221 (the cover plate 221 is hidden in fig. 4), the cover plate 221 is formed by punching the rear cover 2 (usually a metal piece) (only in the form of a small part of a connected fracture), and the cover plate 221 is required to be punched or separated from the position of the second wire inlet 22 when in use. The second wire inlet hole 22 may have two and be symmetrically arranged on the rear cover 2.

Example two

Referring to fig. 9, in the present embodiment, the difference from the first embodiment described above is that the pressing block 41 and the lamp body 11 are integrally formed, and the lamp body 11 is formed with a mounting opening 111 at an opening with the pressing block 41, whereby the elastic piece 42 can be fitted into the pressing block 41 through the mounting opening 111.

Example III

Referring to fig. 10 and 11, in the present embodiment, the difference from the first and second embodiments described above is that the mounting structure includes a combination of a holder 44, a support 45, and an elastic member 46 instead of the elastic piece 42 described above to constitute a pressing member for pressing the press block 41 and the clinching post 43.

Wherein the support 44 is fixed at the opening of the press block 41, at least partially located in the press block 41, the support member 45 extends at least partially in the press block 41, the support member 45 has a first end 451 and a second end 452 opposite to each other, wherein the first end 451 is rotatably connected to the support 44, and the end corresponds to the open end 4111 of the rotation slot 411, the second end 452 of the support member 45 corresponds to the closed end 4112 of the rotation slot 411, and the elastic member 46 abuts between the support member 44 and the second end 452 of the support member 45, such that the second end 452 keeps a tilting trend toward the inside of the rotation slot 411. Preferably, the resilient member 46 is a spring.

When the clinching post 43 rotates to the closed end 4112 of the rotary latch 411 with respect to the pressing block 41, the second end 452 of the support 45 corresponds to the stopper 433 of the clinching post 43. Therefore, in the installation state, the limiting part 433 of the press-riveting column 43 is located in the limiting clamping groove 413, and the second end 452 of the supporting member 45 can press the limiting part 433 of the press-riveting column 43 into the limiting clamping groove 413, so that the press-riveting column 43 and the pressing block 41 are prevented from rotating relatively along the circumferential direction of the lamp body 11.

When the lamp body part 1 and the rear cover 2 need to be disassembled, the lamp body part 1 is jacked up, so that the riveting column 43 presses the second end 452 of the supporting piece 45 downwards, the elastic piece 46 deforms, the limiting part 433 of the riveting column 43 leaves the limiting clamping groove 413 of the pressing block 41, the riveting column 43 can rotate relative to the pressing block 41 again, the disassembly is completed, and the elastic piece 46 can reset when the pressure of the riveting column 43 is not received. By the arrangement of the above-described mounting structure 4, detachment between the lamp body portion 1 and the rear cover 2 can be avoided when there is no pressing action.
