Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically a moisture-proof lamp for cold storage. Background Technology

[0002] Cold storage environments are characterized by high humidity and low temperatures, making ordinary lighting fixtures susceptible to moisture damage and even short circuits, posing safety hazards. Moisture-proof lights, on the other hand, utilize special materials and a sealed design to effectively prevent moisture intrusion, ensuring stable operation in low-temperature and humid environments. They not only provide sufficient and safe lighting for workers in cold storage, ensuring operational accuracy and efficiency, but also extend the lifespan of the lights and reduce maintenance costs.

[0003] Patent document CN221959132U discloses a moisture-proof lamp for cold storage, belonging to the technical field of cold storage lamps. It includes a double-cover cold storage lamp, comprising a lamp holder and an outer cover, connected by bolts. The lamp holder has a mounting opening on its lower side, within which an LED light panel is installed. An inner cover is installed inside the outer cover, with four equally spaced locking blocks around its upper edge. Each locking block engages with a slot located on the upper edge of the outer cover, and a placement groove is provided between every two adjacent slots. Each placement groove contains a moisture-proof adsorption block, thus protecting the LED light panel and providing a double waterproof and moisture-proof structure. This effectively blocks moisture in the cold storage, preventing damage to electronic components from moisture and extending the product's lifespan. However, this patent still has the following problems in practical use:

[0004] This moisture-proof lamp achieves its moisture-proof effect by sealing the double cover with two sets of sealing rings between the lamp base and the lamp cover. However, the sealing rings are prone to shrinkage when exposed to low temperatures during use, which affects the sealing performance of the moisture-proof lamp. In addition, the structure of this moisture-proof lamp is relatively complex, resulting in high production and assembly costs, thus making the lamp less practical.

[0005] Therefore, a moisture-proof lamp for cold storage was proposed to solve the problems mentioned above. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This moisture-proof lamp for cold storage, by setting an H-shaped sealing ring and connecting the upper connecting block, upper connecting groove, lower connecting block and lower connecting groove, facilitates the enhancement of the moisture-proof lamp's sealing performance. Furthermore, when the H-shaped sealing ring shrinks due to low temperatures, it further enhances the fit between the H-shaped sealing ring and the internal threaded sleeve and positioning plate, resulting in a better sealing effect. This simplifies the structure of the moisture-proof lamp, thereby reducing its production and assembly costs. The specific details are as follows:

[0020] 1. This cold storage moisture-proof lamp uses an H-shaped sealing ring to protect the inner threaded sleeve, positioning plate, and outer threaded block at the connection between the lamp holder and the lamp cover. The connection of the upper connecting block, upper connecting groove, lower connecting block, and lower connecting groove enhances the lamp's sealing performance, reducing the risk of moisture entering the lamp and affecting its lifespan. Furthermore, when the H-shaped sealing ring shrinks due to low temperatures, it further strengthens the fit between the H-shaped sealing ring and the inner threaded sleeve and positioning plate, reducing the gap between them and resulting in a better seal. Therefore, this makes the cold storage moisture-proof lamp more practical.

[0021] 2. The moisture-proof lamp for cold storage has a simpler structure by using a lamp holder and an H-shaped sealing groove lamp cover, which facilitates quick installation and reduces production and assembly costs, thus making it more practical. Attached Figure Description
