The face ring mounting plate 21 of the face ring 2 at one end of the lamp body is tightly attached to the side surface of the mounting panel 1. During disassembly, the human hand pulls the lamp body outward. When the force is large enough, the limiting connecting end 32 releases the limiting connection relationship with the face ring 2, and the elastic element 3 can be rotated upward to a vertical state, which facilitates the removal of the lamp from the mounting hole 101.

[0038] In the above embodiment, the installation panel 1 is an object for installing the lamp. For different types of lamps, the installation panel 1 can be a ceiling, a furniture panel, etc.

The elastic element 3 is pivotally connected to the face ring 2 through the fixing shaft 9, which passes through the second connection hole 2201 on one side of the fixing ear 22, the first connection hole 3121 of the curling edge 312, and the second connection hole 2201 on the other side of the fixing ear 22. The structure is stable and reliable. The curling edge 312 is formed by bending one end of the connecting piece 311, which is quick and convenient to process.

[0040] like Figure 5 , 6As shown, the limiting connection end 32 of the elastic element 3 is in the shape of a sheet straight plate, and a limiting through hole 321 is provided on the limiting connection end 32 to be installed and matched with the fixing ear 22, and the fixing ear 22 is provided with a fastening protrusion 23 that is installed and matched with the limiting through hole 321 and protrudes toward the limiting connection end 32.

Specifically, the fastening protrusion 23 includes a limiting protrusion plate 232 that is protruded from the fixing ear 22 toward the limiting connection end 32 and a limiting hook 231 that protrudes upward at the end of the limiting protrusion plate 232.

[0041] Preferably, a plurality of second connection holes 2201 are provided on both mounting posts 221, and a plurality of limiting through holes 321 are correspondingly provided on the limiting plate 222, so as to be installed and matched with mounting panels 1 of different thicknesses. In the invention drawing, there are two limiting through holes, which can be installed and matched with mounting panels 1 of two specifications. Obviously, there can be more limiting through holes.

[0042] like Figure 5 , 6 As shown, the elastic element 3 is a sheet structure, and the elastic end 33 is an M-shaped sheet structure. The elastic end 33 includes a first elastic sheet 331, a second elastic sheet 332, a third elastic sheet 333 and a fourth elastic sheet 334 connected in sequence. The first elastic sheet 331, the second elastic sheet 332, the third elastic sheet 333 and the fourth elastic sheet 334 are connected in sequence to form an M-shaped sheet structure. Obviously, the elastic end 33 can also be other shapes. In order to prevent the elastic end 33 from deforming, the elastic end 33 of the elastic element 3 protrudes downward toward the face ring mounting plate 21 and is provided with a support plate 330 to prevent the elastic end 33 from being deformed by force. The upper surface of the face ring mounting plate 21 is protruded with a support protrusion 225 that cooperates with the support plate 330. In the invention Figure 6 In the embodiment, the middle part of the second elastic sheet 332 is cut and bent to form the support plate 330, and the middle part of the second elastic sheet 332 forms the second elastic sheet through hole 3320. The support plate 330 is formed by cutting and bending the second elastic sheet, which saves materials and is quick to process. Obviously, the support plate 330 can also be separately arranged at other positions of the elastic end 33. The M-shaped structure of the elastic end 33 provides elastic force for the elastic element, and during installation, the elastic end 33 is pinched inward by a person's hand to pass through the installation hole 101.

[0043] like Figure 4 , 5As shown, the structure diagram of the face ring. The face ring is a circular structure, and a middle through hole 201 for mounting the lens 8 is provided in the middle of the face ring mounting plate 21 of the face ring 2, and a supporting protrusion 225 is protruded around the middle through hole 201 on the upper surface of the face ring mounting plate 21, and fixing ears 22 for mounting and matching with the elastic element 3 are connected to both sides of the supporting protrusion 225. The structure of the face ring 2 is simple and compact. The fixing ears 22 of the face ring and the elastic element 3 are stably and reliably mounted.

[0044] Specifically, the fixing ear 22 includes two mounting posts 221 arranged at intervals perpendicular to the face ring mounting plate 21 and a limiting plate 222 connected between the two mounting posts 221.

The face ring 2 created by the present invention has a simple and compact structure. Specifically, the limiting plate 222 is a U-shaped plate, and the U-shaped opening of the limiting plate 222 faces the elastic element 3. The limiting plate 222 includes a limiting bottom plate 2221 at the bottom and limiting side plates 2222 vertically connected to the two ends of the limiting bottom plate 2221. One end of the two limiting side plates 2222 is respectively connected to the two mounting posts 221, and the fastening protrusion 23 is provided on the inner side of the limiting bottom plate 2221. The limiting plate 222 allows the elastic element 3 to be stably mounted on the fixing ear 22.

[0045] The following is combined with Figure 1-6 The installation and disassembly process of the lamp created by the present invention is described in detail.

[0046] When the lamp is installed, the limit connection end 32 is limit-connected with the fixing ear 22, and the limit through hole 321 is hung on the limit hook 231 of the fastening protrusion 23 to prevent the elastic element 3 from rotating. The M-shaped elastic end 33 of the elastic element 3 is pinched by hand, and the elastic end 33 retracts inward, and the lamp is pushed into the mounting hole 101 of the mounting panel 1 from one side of the mounting panel 1. After the lamp body and the elastic element 3 pass through the mounting hole 101, the elastic end 33 restores the elastic force and pops out to both sides, and the end of the elastic end 33 fits tightly with the surface of the other side of the mounting panel 1.

[0047] When the lamp is disassembled, a person pulls the lamp body outward by hand. When the force is large enough, the limiting connection end 32 releases the limiting connection relationship with the face ring 2, and the limiting through hole 321 of the limiting connection end 32 slides out from the limiting hook 231 of the fastening protrusion 23. The elastic element 3 can be rotated upward to a vertical state, and the lamp can be taken out from the mounting hole 101.

[0048] The above content is a further detailed description of the invention in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the invention is limited to these descriptions. For ordinary technicians in the technical field to which the invention belongs, several simple deductions or substitutions can be made without departing from the concept of the invention, which should be regarded as falling within the protection scope of the invention.
