[0051] Embodiment 1

[0052] Figure 1 The structural schematic diagram of the metal spring sheet in one of the angles of the present embodiment is given. Figure 2 The structural schematic diagram of the metal spring sheet after deformation of the present embodiment is given, Figure 3 and Figure 4 The side view and top view of the metal spring sheet after deformation of the present embodiment are given respectively, in combination with reference to Figures 1-4 A metal spring sheet 1 for connecting different parts of a lamp, comprising a fixed part 11 and an elastic connecting part 12, wherein the fixed part is fixedly connected with one part of the lamp (such as a lamp body module), and the elastic connecting part 12 is detachably connected with another part of the lamp (such as a lamp holder with a face ring assembly), so that the two part assemblies of the lamp are detachably connected together.

[0053] In some embodiments, the elastic connecting part 12 and the fixed part 11 can also be a split structure, that is, the elastic connecting part 12 and the fixed part 11 are produced separately, and finally fixed by riveting, screwing or the like.

[0054] The material of the metal spring sheet 1 of the present embodiment can be stainless steel or other hardware with structural rigidity. In the present embodiment, the material of the metal spring sheet 1 is high-elasticity stainless steel.

[0055] The elastic connecting part 12 of the present embodiment is located below the fixed part 1. The elastic connecting part 12 and the fixed part 11 are integrally stamped and formed, so that the fixed part 11 can ensure the structural strength when fixedly connected, so that the connection is stable; the elastic connecting part 12 is a resettable elastic part, so that the metal spring sheet 1 can be used multiple times and is easy to disassemble, reducing the use cost of the lamp.

[0056] The elastic connecting part 12 comprises a first deformation part 121 and a second deformation part 122, which form corresponding deformation regions and generate clamping force to clamp and connect with other lamp parts.

[0057] Specifically, the first deformation part 121 is formed by bending the lower end of the fixed part 11 towards the inner side of the metal spring 1 first, and then extending vertically downward; the second deformation part 122 is formed by bending the lower end of the first deformation part 121 towards the outer side of the metal spring first, and then bending towards the inner side of the metal spring.

[0058] As shown in Figure 3 , the second deformation part 122 bends towards the outer side of the metal spring to form a first bending surface 1221, and bends towards the inner side of the metal spring to form a second bending surface 1222, the included angle between the first deformation part 121 and the first bending surface 1221 is θ1, and the included angle between the first bending surface and the second bending surface is θ2, wherein θ1≥θ2.

[0059] More specifically, the included angle θ1 between the first deformation part 121 and the first bending surface 1221 is ≥90°, and the included angle θ2 between the first bending surface and the second bending surface is ≤90°.

[0060] As shown in Figure 4 , the groove 123 of the embodiment separates the elastic connecting part 12 into two clamping units 120; in some embodiments, multiple grooves 123 can be provided to separate the elastic connecting part 12 into multiple clamping units.

[0061] It can be understood that the clamping unit 120 is a clamping part composed of the first deformation part 121 and the second deformation part 122, and an included angle θ3 is formed between two adjacent clamping units 120; in this embodiment, the included angle θ3 is an obtuse angle, that is, in each clamping unit 120, the horizontal distance between the second deformation part 122 and the first deformation part 121 gradually increases from the outer side to the groove 123, so that the clamping force of the clamping unit 120 gradually increases from the outer side to the groove 123, which can ensure the continuity of the clamping force and the stability of the two lamp parts connected by the metal spring 1.

[0062] Figure 4A The schematic diagrams of the metal spring before and after deformation of the embodiment are shown, wherein the dashed line indicates the state diagram of the second deformation part of the metal spring after deformation. As shown in Figures 1-4 and Figure 4AIt can be seen that, based on the above bending and angle structure basis, when the metal elastic sheet 1 is connected with other lamp parts, the first deformation part 121 and the second deformation part 122 of the elastic connecting part 1 are deformed, especially the second deformation part 122 is elastically deformed to generate a circular arc reverse force, which can be elastically connected with different parts of other lamp parts such as a support, thereby effectively buckling connection, enhancing the reliability and stability of the connection of the lamp parts.

[0063] It should be noted that the groove 123 provided in the elastic connecting part 12 can further increase the arc deformation of the first deformation part 121 and the second deformation part 122, and then the first deformation part 121 of the elastic connecting part 12 is deformed to generate a reverse force, thereby improving the buckling stability of the second deformation part and other parts.

[0064] Back to Figure 1 and Figure 2 The clamping jaw 11 is provided in the fixed part 11 of the metal elastic sheet 1, which is formed by bending the side wall of the fixed part 11 inward, and is used for clamping and fixing the lamp parts connected with the metal elastic sheet 1. In addition, the fixed part 11 is provided with a first through hole 112 for the fastener to pass through and be fixedly connected. In this embodiment, the first through hole 112 is located at the center of the fixed part 11.

[0065] The metal elastic sheet of the embodiment is provided with an elastic connecting part below the fixed part, which is integrally formed with the fixed part, and has a first deformation part and a second deformation part, which can be deformed and reset according to the connected lamp parts, and can be used repeatedly, so that the connected lamp parts can be disassembled and assembled repeatedly, facilitating the maintenance and replacement of the lamp parts, and reducing the use cost.

At the same time, the clamping jaw 111 of the fixed part 11 is also buckled with the protrusion 21, which ensures that the connection between the metal spring 1 and the first ring body 2 is stable and reliable.

[0070] The first ring body 2 of the present embodiment is provided with three protrusions 21 protruding on the side wall, and the number of metal springs 1 is also three. In addition, the fastener 4 can be a rivet or a countersunk screw, and the present embodiment selects a rivet as the fastener to fix the fixed part 11 with the protrusion 21, and then the first ring body 2 and the metal spring 1 are also fixed.

[0071] The second ring body has a support function, and in the connection between the metal spring 1 and the second ring body 3, the elastic connecting part 12 is buckled with the second ring body. Specifically, the outer side of the first deformation part 121 abuts against the inner side of the protrusion 31, and is deformed to present an arc-shaped structure that fits the protrusion. The two are closely matched. In addition, the first deformation part 121 that has been deformed generates a reaction force, which further improves the clamping force of the second deformation part 122 with the groove 32, so that the outer side of the second deformation part 122 is closely abutted against the inner side of the groove 32, thereby providing multiple abutting positions for the connection between the metal spring and the second ring body, and tightly buckling the metal spring in the second ring body.

[0072] In the lamp connecting mechanism of the present embodiment, the metal spring is fixed with the first ring body, and then buckled with the second ring body which serves as a support function, so that the first ring body and the second ring body are detachably buckled, realizing the convenient disassembly and installation function of pressing type.
