Description

Technical Field

[0001] This utility model relates to the field of lampshades, and in particular to a corrosion-resistant lampshade. Background Technology

[0002] In production environments such as chemical, electroplating, and printing and dyeing industries, there are large amounts of corrosive acids and alkalis. Ordinary lampshades are easily corroded and damaged in such environments, leading to decreased light transmittance and weakened structural strength. This not only affects lighting performance but may also pose safety hazards. Currently, some corrosion-resistant lampshades on the market either lack sufficient corrosion resistance in their materials or are structurally designed to ineffectively prevent the intrusion of corrosive media, making it difficult to meet actual usage requirements. Utility Model Content

[0003] This application provides a corrosion-resistant lampshade, which solves the technical problem that ordinary lampshades in the prior art are easily corroded and damaged in the production environment of industries such as chemical, electroplating, and printing and dyeing, resulting in a decrease in the light transmittance and a weakening of the structural strength. At the same time, some corrosion-resistant lampshades on the market either have insufficient corrosion resistance in their materials or cannot effectively prevent the intrusion of corrosive media in their structural design, making it difficult to meet the technical requirements of actual use.

[0004] The technical solution adopted in the embodiments of this application is as follows:

[0005] A corrosion-resistant lampshade includes a lampshade body, a lamp head, a cover plate, a waterproof connector, and bolts; the lampshade body is a cylindrical structure; the lamp head is disposed inside the lampshade body and is sealed to the lampshade body; the cover plate is installed on the top of the lampshade body and is connected by the bolts with sealing washers; the waterproof connector is screwed onto the cover plate, and the waterproof connector is provided with elastic sealing material inside.

[0006] A further technical solution is that both the lampshade body and the lamp head are made of acid and alkali resistant engineering plastics.

[0007] A further technical solution is as follows: a silicone rubber sealing gasket is provided between the cover plate and the lampshade body, and the bolts are made of corrosion-resistant plastic material.

[0008] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0009] 1. Due to the use of a lampshade body, lamp holder, cover plate, waterproof connector, and bolts, this corrosion-resistant lampshade, by employing acid and alkali-resistant engineering plastics (such as PVDF) for its core components such as the lampshade body and lamp holder, fundamentally improves corrosion resistance. Experimental data shows that its acid and alkali resistance lifespan is significantly improved compared to traditional PC materials. The fully enclosed structure, combined with the silicone rubber sealing ring between the flange cover and the lampshade body, effectively prevents the intrusion of corrosive media. The unique waterproof connector design achieves dynamic sealing at the wire entry point through the radial compression deformation of the elastic rubber sleeve, solving the problem of easy aging and failure of traditional potting processes. The smooth surface treatment reduces the adhesion rate of corrosive substances, and the modular assembly structure allows for rapid on-site replacement of damaged parts. This corrosion-resistant lampshade is suitable for chemical workshops, laboratories, wastewater treatment facilities, and other places with acid and alkali corrosive environments, providing these areas with a safe, reliable, and durable lighting solution.

[0013] This application provides a corrosion-resistant lampshade, which solves the technical problem that ordinary lampshades in the prior art are easily corroded and damaged in the production environment of industries such as chemical, electroplating, and printing and dyeing, resulting in a decrease in the light transmittance and a weakening of the structural strength. At the same time, some corrosion-resistant lampshades on the market either have insufficient corrosion resistance in their materials or cannot effectively prevent the intrusion of corrosive media in their structural design, making it difficult to meet the technical requirements of actual use.

[0014] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0015] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0016] A type of corrosion-resistant lampshade, such as Figure 1 and Figure 2As shown, the lamp includes a lampshade body 1, a lamp holder 3, a cover plate 4, a waterproof connector 5, and bolts 6. The lampshade body 1 has a cylindrical structure. The lamp holder 3 is located inside the lampshade body 1 and is sealed to it. The cover plate 4 is installed on the top of the lampshade body 1 and is connected by bolts 6 with sealing washers. The waterproof connector 5 is screwed onto the cover plate 4, and the interior of the waterproof connector 5 is filled with elastic sealing material.

[0017] Both the lampshade body 1 and the lamp holder 3 are made of acid and alkali resistant engineering plastics.

[0018] A silicone rubber sealing gasket is provided between the cover plate 4 and the lampshade body 1, and the bolts 6 are made of corrosion-resistant plastic.

[0019] In this embodiment, the corrosion-resistant lampshade is injection molded from polyvinylidene fluoride (PVDF) engineering plastic. The lampshade body 1 is a cylindrical structure with a light transmittance of 90%. The wall thickness of the lampshade body 1 has been optimized to reduce weight while ensuring sufficient strength, and the surface is smooth to reduce the adhesion of corrosive substances. During assembly, the lamp head 3 of the integrated LED lamp 2 is first inserted into the central slot of the flange cover 4 and fixed with plastic screws 6. After placing a sealing ring on the edge of the flange cover 4, it is evenly tightened to the top of the lampshade body 1 with six sets of plastic bolts. Finally, the power cord is passed through the waterproof connector 5 with a rubber sleeve and screwed into the threaded hole of the flange cover 4 and tightened to form a triple sealing structure. Actual tests show that the lampshade did not show corrosion penetration after continuous operation in a sulfuric acid mist environment for a long time.

[0020] By incorporating a lampshade body 1, lamp holder 3, cover plate 4, waterproof connector 5, and bolts 6, this corrosion-resistant lampshade, using acid and alkali-resistant engineering plastics (such as PVDF) for its core components such as the lampshade body 1 and lamp holder 3, fundamentally improves its corrosion resistance. Experimental data shows that its acid and alkali resistance lifespan is significantly longer than that of traditional PC materials. The fully enclosed structure, combined with the silicone rubber sealing ring between the flange cover 4 and the lampshade body 1, effectively prevents the intrusion of corrosive media. The unique waterproof connector 5 design achieves dynamic sealing at the wire entry point through the radial compression deformation of the elastic rubber sleeve, solving the problem of easy aging and failure of traditional potting processes. The smooth surface treatment reduces the adhesion rate of corrosive substances, and the modular assembly structure allows for rapid on-site replacement of damaged parts. This corrosion-resistant lampshade is suitable for places with acid and alkali corrosive environments such as chemical workshops, laboratories, and wastewater treatment facilities, providing these areas with a safe, reliable, and durable lighting solution.
