Description

TECHNICAL FIELD

[0001] The utility model relates to underwater lamp technical field especially relates to a face cover locking fixing device of underwater lamp. BACKGROUND

[0002] Underwater lighting lamps are widely used in aquariums, swimming pools, underwater landscape lighting and other occasions. Due to the special working environment, underwater lighting lamps must withstand underwater high pressure, corrosion and temperature changes and other complex environmental factors. Among them, the sealing performance is one of the key indicators to measure the performance of underwater lighting lamps.

[0003] In the manufacturing process of stainless steel underwater lamps, in order to ensure that the electronic components inside the lamp are not eroded by water, a sealing ring is usually arranged between the face cover and the lamp shell, and the sealing structure is formed by pressing. This structure is crucial to the waterproof performance and long-term stable operation of the lamp.

[0004] The traditional way is to directly connect and press by screws, but this method has some disadvantages, and the disadvantages of directly pressing and fixing the sealing structure by screws are as follows:

[0005] 1. Complicated installation

[0006] There are 4 or more screws, and more for large size lamps, which need to align the screw holes and apply appropriate torque to the screws to ensure the sealing effect, so the installation process is relatively complicated and time-consuming. If installed improperly, such as some screws are not tightened or over-tightened, it may cause poor sealing, damage the sealing ring, and thus affect the waterproof performance of the lamp.

[0007] 2. Instability of sealing performance

[0008] Some screws may loosen due to water wave vibration, corrosion or temperature change and other factors during long-term use, resulting in a decrease in sealing performance. The loosened screws may cause uneven stress on the sealing ring, thereby causing leakage risk in some areas.

[0009] 3. High maintenance cost

[0010] During lamp maintenance, it is necessary to regularly check and tighten the screws one by one to ensure the sealing performance. This increases the complexity and cost of maintenance. If some screws are stuck due to corrosion and wear, they cannot be loosened, which may require replacement of the entire lamp, further increasing the maintenance cost. INVENTION CONTENT
