Description

Technical Field

[0001] The present invention belongs to the technical field of lighting fixtures, and particularly relates to a replaceable magnetic reflection cup structure. Background Art

[0002] Basically, replaceable reflection cups on the current market all adopt screw thread or bayonet structures. The disadvantages of the screw thread structure are as follows: 1. Both installation and disassembly are time-consuming, and it takes multiple turns of rotation to be installed in place; 2. The requirements for the lamp body are quite strict. Once deformed or out-of-round, it will cause jamming or inability to disassemble during installation and disassembly; 3. The reflection cup adopts plastic injection molding process, and it is difficult to achieve diverse colors, especially processes such as electroplating and wire drawing. The disadvantages of the bayonet structure are as follows: 1. The bayonet needs to have a certain toughness, and generally plastic parts are used. Over time, it is prone to aging and there is a risk of loosening or even falling off; 2. The bayonet snap-in installation is simple, but the disassembly is relatively difficult. Many companies replace the new reflection cup by damaging the reflection cup. Summary of the Invention

[0003] In order to solve the above technical problems, based on the rich experience accumulated by the inventor in the technical field of lighting fixtures, a replaceable magnetic reflection cup structure is developed.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A replaceable magnetic reflection cup structure, comprising: a reflection cup module, the reflection cup module includes a reflection cup and a magnetic adsorption bracket, the magnetic adsorption bracket is riveted to the reflection cup by a metal rivet, taking the center point of the reflection cup as a reference, the included angle between two adjacent magnetic adsorption brackets is α, and α = 120°; a spring piece, the spring piece is fixed to the front of the radiator by a screw, the spring piece includes a first bending portion, a second bending portion, a third bending portion and a protrusion; the end of the magnetic adsorption bracket far from the reflection cup is located below the second bending portion, and a gap is formed between the magnetic adsorption bracket and the second bending portion; a magnet, the magnet is fixed to the back of the radiator by glue, the magnet is located directly below the spring piece, and the magnet is magnetized along the thickness direction.

[0005] The reflection cup adopts a spinning aluminum process, is not easily deformed and aged, can be sprayed and electroplated to achieve diverse colors; three evenly distributed magnetic adsorption brackets are fixed below it, and the magnetic adsorption brackets are made of SGCC galvanized iron sheet and are adsorbed to the magnet.

[0006] The magnet is made of neodymium boron silicon material, that is, a permanent magnet. And it will never demagnetize within 150 °C; the magnet is magnetized along the thickness direction to ensure that the magnet has the maximum suction force on the A surface (the A surface of the magnet is the adsorption surface with the magnetic adsorption bracket).

[0007] The magnet is made of SUS304 material and has good toughness; the elastic piece is fixed to the front of the radiator by screws and is installed corresponding to one of the magnet A faces; the end of the elastic piece is upturned to facilitate the smooth sliding in when the magnetic suction bracket rotates.

[0008] Further, the inner diameter of the bottom of the reflector cup is d, 7 mm < d < 8 mm; the inner diameter of the top surface of the reflector cup is D, 20 mm < D < 22 mm; the height of the inner curved surface of the reflector cup is H, 12 mm < H < 13 mm; the inner curved surface of the reflector cup includes a first light-condensing section h1, a second light-condensing section h2, and a third light-condensing section h3 in sequence from the bottom to the top. The curvature of the first light-condensing section h1 is k1, and k1 is between 0.0222 and 0.0228; the curvature of the second light-condensing section h2 is k2, and k2 is between 0.0228 and 0.0251; the curvature of the third light-condensing section h3 is k3, and k3 is between 0.0251 and 0.0322.

[0009] Further, the first bending part is located at the rightmost side of the elastic piece. The left side of the first bending part is connected to the right side of the second bending part, and the left side of the second bending part is connected to the right side of the third bending part. The third bending part is in a "V" shape. The protrusion is arranged on the first bending part. The horizontal plane height of the first bending part is H1, the horizontal plane height of the second bending part is H2, and the horizontal plane height of the lowest point of the "V" shape of the third bending part is H3, and H1 = H2 > H3.

[0010] Further, place the reflector cup module flat on the surface of the radiator, that is, outside the elastic piece, and rotate it counterclockwise. The magnetic suction bracket will be quickly adsorbed directly above the magnet; when disassembling the reflector cup, rotate the reflector cup clockwise to the outside of the elastic piece, and it can be separated from the suction force of the magnet.

[0011] Further, the reflector cup module is installed in the lamp barrel, and its outer circle is concentrically installed with the inner circle of the lamp barrel.

[0012] Further, the number of the magnetic suction brackets, elastic pieces, and magnets is the same.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention utilizes the magnetic induction line distribution characteristics of the magnet and disassembles the reflector cup by rotating the reflector cup to cut the magnetic induction lines, which is convenient and labor-saving.

[0015] 2. When installing the reflector cup, rotate the reflector cup module. After the magnetic suction bracket slides into the elastic piece, it is quickly adsorbed by the magnet. There is a strong adsorption feeling during installation, and it can be easily determined whether the reflector cup is installed in place.

[0016] 3. After installation, the distance between the shrapnel and the magnetic adsorption bracket is particularly important. When the magnetic adsorption bracket is separated from the magnet due to external forces (such as impact, earthquake, transportation, etc.), it will be blocked by the shrapnel. At this time, the separated distance can still ensure that the magnetic adsorption bracket will be adsorbed back by the magnet, achieving the purpose that the reflector cup will never fall off.

[0017] 4. The lamp cylinder and the reflector cup are installed concentrically. By using the limiting effect of the lamp cylinder on the reflector cup, only one shrapnel needs to be installed on the radiator to ensure that it will not fall off even if all three magnets fail; this saves costs and at the same time users can use it with more confidence.

[0018] 5. Three magnetic adsorption brackets are installed below the reflector cup module, corresponding to the three magnets on the radiator one by one, ensuring the balanced force during the installation of the reflector cup, and the feeling of installation and disassembly is smooth without jamming;

[0019] 6. The reflector cup is made of aluminum, and its surface can be spray-painted or electroplated, which is well recognized by consumers. Description of the Drawings

[0031] The reflector cup 2 adopts a spinning aluminum process, is not easy to deform and age, can be sprayed and electroplated, achieving color diversification; three evenly distributed magnetic adsorption brackets are fixed below it, and the magnetic adsorption bracket 3 is made of SGCC galvanized iron sheet and adsorbs with the magnet 7.

[0032] The magnet is made of neodymium boron silicon material, that is, a permanent magnet. And it will never demagnetize within 150 °C; the magnet is magnetized along the thickness direction to ensure that the magnet has the maximum suction force on the A surface (the A surface of the magnet is the adsorption surface with the magnetic adsorption bracket).

[0033] The magnet is made of SUS304 material and has good toughness; the elastic piece 6 is fixed to the front of the radiator 5 by screws and is correspondingly installed with the A surface of one of the magnets 7; the end of the elastic piece 6 is upturned to facilitate the smooth sliding in when the magnetic absorption bracket 3 rotates.

[0034] In this embodiment, the inner diameter of the bottom of the reflecting cup 2 is d, 7 mm < d < 8 mm; the inner diameter of the top surface of the reflecting cup 2 is D, 20 mm < D < 22 mm; the height of the inner curved surface of the reflecting cup 2 is H, 12 mm < H < 13 mm; the inner curved surface of the reflecting cup 2 successively includes a first light condensing section h1, a second light condensing section h2 and a third light condensing section h3 from the bottom to the top. The curvature of the first light condensing section h1 is k1, and k1 is between 0.0222 and 0.0228; the curvature of the second light condensing section h2 is k2, and k2 is between 0.0228 and 0.0251; the curvature of the third light condensing section h3 is k3, and k3 is between 0.0251 and 0.0322.

[0035] In this embodiment, the first bending portion 601 is located at the rightmost side of the elastic piece 6. The left side of the first bending portion 601 is connected to the right side of the second bending portion 602, and the left side of the second bending portion 602 is connected to the right side of the third bending portion 603. The third bending portion 603 is in a "V" shape. The protrusion 604 is arranged on the first bending portion 601.

[0039] In this embodiment, when the rotating reflecting cup 2 is disassembled by the rotation scheme, the magnetic absorption bracket 3 at its lower end moves along the direction of cutting the magnetic induction line, and the magnetic force quickly decreases, which is extremely labor-saving and convenient. The larger the air gap 9 between the magnet 7 and the attracted object, the weaker the suction force. When the lamp is impacted or shaken, the reflecting cup 2 will break away from the magnet 7 due to inertia to generate the air gap 9, and the elastic piece 6 can ensure that the air gap 9 is within the effective range; after the magnetic absorption bracket 3 of the reflecting cup touches the elastic piece 6, it will still be quickly adsorbed by the magnet 7, so as to achieve the purpose that the reflecting cup 2 can cope with various environments and is not easy to fall off.
