To the weak point that exists in the above-mentioned problem, the utility model provides a waterproof ornament lamp dispels the heat.

For realizing the above-mentioned purpose, the utility model provides a waterproof ornament lamp dispels heat, include, lamp shade and lamp stand, the portion of screwing of lamp shade bottom processing, the portion of screwing in the middle of the portion of screwing, the lamp stand is inside to be the cavity, the cavity top with surface connection department processes the inclined plane on the lamp stand, cavity upper portion processing convex part I, the portion of screwing stretches into cavity upper portion, convex part I matches the recess, cavity upper portion central axial symmetry processing has four stoppers, place the light source circuit board on the stopper, the welding has the power cord on the light source circuit board, cavity bottom installation sealing washer, two through-holes of sealing washer central axial symmetry processing, the power cord passes the through-hole, sealing washer upper portion surface processing convex part II.

As a further improvement, the outer surface of the lampshade is in interference contact with the inclined plane.

As a further improvement, the diameter of the through hole is matched with the diameter of the power line.

As the utility model discloses further improve, the number of convex part II is two at least, II diameters of convex part are greater than cavity bottom internal diameter.

The utility model has the advantages that:

1. the outer surface of the lampshade is in contact with the surface of the lamp holder cavity, and the sealing ring and the lamp holder cavity are self-sealed, so that a waterproof function can be realized without additional working procedures;

2. because the lamp holder cavity is hollow, the decorative lamp has better heat dissipation performance and the service life of the decorative lamp is prolonged.

In the figure: 1. a lamp shade; 11. a tightening part; 111. a groove; 2. a lamp socket; 21. a cavity; 211. a bevel; 212. a convex part I; 213. a limiting block; 3. a light source circuit board; 4. a power line; 5. a seal ring; 51. a convex part II; 52. and a through hole.

Detailed Description

As shown in figure 1, the heat-dissipating waterproof decorative lamp according to the embodiment of the present invention comprises a lamp cover 1 and a lamp holder 2, a screwing portion 11 is processed at the bottom of the lamp cover 1, a groove 111 is processed in the middle of the screwing portion 11, a cavity 21 is formed inside the lamp holder 2, an inclined plane 211 is processed at the connection position of the top of the cavity 21 and the upper surface of the lamp holder 2, the outer surface of the lamp cover 1 is in interference contact with the inclined plane 211, a convex portion I212 is processed at the upper portion of the cavity 21, the screwing portion 11 extends into the upper portion of the cavity 21, the convex portion I212 is matched with the groove 111, four stoppers 213 are processed at the central axial symmetry at the upper portion of the cavity 21, a light source circuit board 3 is placed on the stoppers 213, a power wire 4 is welded on the light source circuit board 3, a sealing ring 5 is installed at the bottom of the cavity 21, the number of the convex parts II 51 is at least two, and the diameter of the convex parts II 51 is larger than the inner diameter of the bottom of the cavity 21.

The outer surface of the lampshade is in contact with the surface of the lamp holder cavity, and the sealing ring and the lamp holder cavity are self-sealed, so that a waterproof function can be realized without additional working procedures; because the lamp holder cavity is hollow, the decorative lamp has better heat dissipation performance and the service life of the decorative lamp is prolonged.

When in specific use, the utility model is described with the attached drawings for the convenience of understanding;

during the assembly, place the light source circuit board on the stopper, the lamp shade portion of screwing is during downwards detaining the lamp stand cavity, make I card of convex part go into in the recess, the lamp shade surface is interference contact with the inclined plane, plastic housing produces corresponding deformation, the inclined plane at cavity top and the surperficial face contact that forms of lamp shade, the portion bottom surface of screwing simultaneously pushes down the light source circuit board and makes it fixed, press on sealing washer upper portion and stretch into the cavity bottom, because II diameters of convex part are greater than cavity bottom internal diameter, sealing washer and cavity surface in close contact with, the power cord passes the through-hole connection power in the middle of the sealing washer, form the self sealss from this, realize waterproof function, because the cavity is inside hollow.
