Embodiment Construction

[0022] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. refer to figure 1 and 2 , The waterproof and sealed lamp includes a lower cover (also called a lamp body) 1, an upper cover 2 and a light source 6. The lower cover 1 has a cavity for installing the light source 6 . The upper cover 2 is hinged on the upper side of the lower cover 1 through a pin shaft 3 . The upper cover 2 has a sealing groove 4 at its inner periphery. A transitional sealing ring 5 is embedded in the sealing groove 4 . Of course, the present invention is not limited thereto, and the sealing groove 4 can also be provided on the lower cover 1 . When opening and closing the cover, the upper cover 2 can rotate around the pin shaft 3 . In addition, a fastening mechanism is provided between the upper cover 2 and the lower cover 1 to realize disassembly and connection between the two.

Abstract

The invention relates to a waterproof sealing lamp, comprising a lower cover (1) and an upper cover (2) hinged on the lower cover (1) through a pin shaft (3). The upper cover (2) is provided with a sealing groove (4) in which a transitional sealing ring (5) is contained, wherein the thickness (d) of the transitional sealing ring (5) gradually increases towards a direction away from the pin shaft (3). As the thickness of the transitional sealing ring in the invention gradually increases towards the direction away from the pin shaft, the cover closing force is even and rational during the cover closing of the lamp, the compression amounts at different positions are consistent, the reliability of the waterproof lamping lamp is improved, and the cover closing process is simplified.

Description

technical field [0001] The invention belongs to the field of lighting. More specifically, the present invention relates to a lighting fixture with a cover structure connected by a pin shaft, which can make the cover of the lamp easier and effectively ensure the waterproof and sealing performance of the lamp. Background technique [0002] Traditionally, for a waterproof and sealed lamp that uses a pin shaft to connect the upper cover and the lower cover of the lighting fixture, when sealing the lighting fixture, a waterproof sealing ring is usually provided between the upper cover and the lower cover. When closing the cover, the part near the pin shaft on the waterproof sealing ring is compressed first, and the part far away from the pin shaft is compressed later. As a result, the closer to the pin shaft, the greater the compression, which leads to problems such as inconsistent compression and difficulty in closing the lid. The inconsistent compression of each part of the se...
