Description

CROSS REFERENCE TO THE RELATED APPLICATIONS

TECHNICAL FIELD

The present disclosure relates to the technical field of lamps, in particular, to an underwater diving light with efficient waterproof performance.

BACKGROUND

Underwater lamps, which refer to lights installed under the water, are small, delicate and elegant in appearance, and may emit light under the water to enhance an ambient atmosphere and improve people's sense of pleasure.

Commonly used underwater lights need to work underwater, so they have certain requirements for waterproof performance. Generally, the water is prevented from entering the lights through housings of the underwater lights, so as to avoid damage to parts inside the underwater lights. After long-term use, the water still leaks into the underwater lights. Usually, waterproof rings are arranged at the joints of the housings to prevent the water from leaking into the underwater lights from the joints.

However, the underwater lights installed with the waterproof rings currently have the following problems: when the housings of the underwater lights are tightened, the waterproof rings will be driven and then extruded and deformed, and the water will seep into wrinkled positions of the waterproof rings to cause water leakage. In addition, the existing underwater lights have a single luminous form and may not achieve a dazzling effect.

In view of the above-mentioned related technologies, the inventors of the present disclosure provide modifications and improvements to the existing underwater lamps.

Embodiment 4

A difference from the embodiment 1, the embodiment 2 and the embodiment 3 is that, referring to FIGS. 14-17, in this embodiment, a special-shaped light-transmitting seal 2 further includes a vacuum suction part 205; the vacuum suction part 205 is annular and connected with a first installation part 201; the vacuum suction part 205 is provided with clamping strips 207 and an elastic suction cup 206 configured to cooperatively suck the bottom of a first installation groove 103; the clamping strips 207 are arranged on an outer edge of the elastic suction cup 206; a clamping groove 208 configured to accommodate the clamping strips 207 are formed in a joint between an inner groove wall of the first installation groove 103 and the bottom of the first installation groove 103 in a sunken manner; and through the vacuum suction part 205, when a light housing is tightened, the vacuum suction part 205 and the bottom of the first installation groove 103 are subjected to vacuum suction and fixation to prevent a deformation-resistant sealing ring from being extruded and deformed, which is beneficial to prevent water from seeping into a light housing at a deformed wrinkled position to cause damage. A specific installation principle of the special-shaped light-transmitting seal 2 is as follows: referring to FIG. 14 and FIG. 15, the first installation part 201 of the special-shaped light-transmitting seal 2 is accommodated in the first installation groove 103, and clamping strips 207 of an elastic suction cup 206 are in contact with the bottom of the first installation groove 103; then, referring to FIG. 16 and FIG. 17, in a process of gradually tightening and fixing a top cover 1 and a bottom cover 3, an edge of the bottom cover 3 is in contact with a force-receiving part, and the force-receiving part is gradually pressed to move toward the bottom of the first installation groove 103, so that the air in the elastic suction cup 206 is pressed out; and referring to FIG. 15, a section of the elastic suction cup 206 is conical, and the elastic suction cup 206 is one 206 made of a silica gel material or other elastic materials. Next, an inner surface of the elastic suction cup 206 is completely close to the bottom of the first installation groove 103, so that a space formed between the elastic suction cup 206 and the bottom of the first installation groove 103 has a pressure difference with the outside, and the elastic suction cup 206 of the deformation-resistant sealing ring is pressed at the bottom of the first installation groove 103 by the outside air to be fixed. Meanwhile, the clamping strips 207 are extended during unfolding of the elastic suction cup 206 to be accommodated in the clamping groove 208 to realize an insertion connection. In this way, when the top cover 1 and the bottom cover 3 are tightened, since the deformation-resistant sealing ring is sucked to the bottom of the first installation groove 103 through the elastic suction cup 206, the deformation-resistant sealing ring is prevented from being extruded and deformed to form the wrinkled position, thereby improving the waterproof performance, and preventing the water from seeping into the light housing. Meanwhile, since the top cover 1 and the bottom cover 3 generally rotate in a horizontal direction, wrinkling is caused in an extrusion deformation direction that is a vertical direction; an area in the horizontal direction is enlarged by the clamping strips 207 to increase the difficulty of wrinkling and further improve the waterproof performance; and preferably, the clamping groove 208 of the clamping strips 207 is the annular clamping groove 208 of the annular clamping strips 207.
