Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment

[0029] See Figures 1 to 3 As shown, a sealed moisture-proof lamp includes a lamp holder 1, a light source board 2 fixed in the lamp holder, and a lamp shade 3 arranged at the illumination opening of the lamp holder. In this embodiment, both the lamp holder and the light source board are conventional structures of the prior art and are only simply applied, so they are not described in detail. At the same time, the lamp shade is also a conventional material structure of the prior art.

[0030] During actual application, a cavity 4 is arranged inside the side wall of the lamp holder, and upwardly inclined buckle tabs 5 are arranged on both the inner wall and the outer wall of the lamp holder; the thickness of the buckle tabs can be processed and set as required. At the same time, a convex frame 6 is integrally formed at the edge of the top surface of the lamp shade, a clamping cavity 7 with an opening at the top surface is arranged inside the convex frame, and downwardly inclined clamping position protrusions 8 are arranged on the symmetrical inner walls of the clamping cavity; in this embodiment, the width of the clamping cavity is slightly larger than the thickness of the side wall of the lamp holder. At the same time, under the action of an external force, the edge of the lamp holder is clamped downward into the clamping cavity. When clamping, the clamping position protrusion deforms to enable the buckle tab to be clamped. After the buckle tab is clamped, the clamping position protrusion is reset and clamped into the buckle tab to achieve mutual engagement and positioning, preventing loosening or falling off. During actual application, the number of the buckle tabs and the clamping position protrusions can be one or more.

[0031] At the same time, during actual application, the cavity is filled with drying particles 9; in this embodiment, the drying particles are silica gel drying particles, fiber drying particles or activated carbon drying particles. It is mainly used to absorb water vapor and ensure the moisture-proof performance inside the lamp.

[0032] During assembly, the bottom edge of the lamp holder is snapped into the card cavity, and the snap tab and the positioning protrusion are engaged and positioned with each other; a sealing potting layer 10 is filled in the card cavity. And it seals the connection between the lamp holder and the card cavity through the sealing potting layer, ensuring waterproof, dustproof and moisture-proof performance, with strong practicability. The sealing potting layer is a sealant of the prior art, so it is not described in detail.

[0033] During actual application, a U-shaped buckle 12 is rotatably connected to the outer wall of the lamp holder through a pin shaft 11; a convex block 13 is integrally formed on the outer wall of the convex frame; the U-shaped buckle rotates around the pin shaft and is buckled on the convex block for limiting. Through the above structure, the reliability of the connection between the two can be ensured, preventing loosening or falling off.

[0034] During actual application, a wire through hole 14 inclined from the inside to the outside is provided on the lamp holder, and the inclined high end of the wire through hole is on the inner wall of the lamp holder; the wire 21 of the light source board is arranged in the wire through hole, and a sealant layer 15 is poured at the connection between the wire and the wire through hole. It adopts a downwardly inclined wire through hole, which can prevent rainwater from draining into the lamp through the wire, improving the sealing performance, and the sealant layer can further ensure the sealing performance of the connection.

[0035] During actual application, a U-shaped wire guiding part 16 is integrally formed on the outer wall of the lamp holder, and a wire clamping groove 17 is on the arched outer surface of the U-shaped wire guiding part; the U-shaped wire guiding part is at the upper surface of the outer side end of the wire through hole; a pressing piece 19 is rotatably connected to the opening of the wire clamping groove through a shaft convex 18; during installation, the wire is in the wire clamping groove and is clamped and limited by the pressing piece. Through the above structure, the wire can be prevented from breaking at the wire through hole, and is guided by the U-shaped wire guiding part to make the wire have an arc transition. When connecting to the outside, the wire can be prevented from breaking, and during actual application, the wire clamping groove is potted with a glue sealing layer 20. It can further improve the anti-bending performance of the wire and also prevent rainwater from draining into the lamp.

[0036] The utility model has positive effects: The structure of the utility model is reasonably arranged. It has a convex frame on the lamp cover, and a card cavity on the top surface of the convex frame. At the same time, there are snap tabs on the inner and outer walls of the lamp holder. During installation, the bottom edge of the lamp holder is inserted into the card cavity and is engaged and positioned with the positioning protrusion through the snap tab, and is sealed through the sealing potting layer, improving the stability and reliability of the installation. At the same time, it is also beneficial to improve the waterproof and moisture-proof performance. Moreover, there are drying particles in the cavity of the lamp holder, which further improves the sealing performance and moisture-proof performance in cooperation with the sealing potting layer. The assembly is more convenient, the use is stable and reliable, and the applicability and practicability are good.

[0037] The standard parts used in this embodiment can be directly purchased from the market, and the non-standard structural components described in the specification can also be directly processed without doubt according to the existing common technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology. Therefore, no specific description will be made here.

[0038] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or modifications derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
