Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a waterproof sign lamp structure. Background Art

[0002] When fire emergency sign lights are installed in humid places, or when a fire occurs, the fire protection system in the public building is activated to sprinkle water to extinguish the fire. Firefighters use water guns to carry out firefighting and rescue. Water will enter the lamp through various means, causing a short circuit in the circuit board, resulting in the lamp being unable to work, making it impossible to guide the trapped people to evacuate or carry out firefighting and rescue work.

[0003] The existing base shell of fire emergency sign lights mostly consists of a base shell and a cover, and the installation method is mostly to set a hanging hole on the base shell, and the sign light is installed on the wall through the hanging hole. The hanging hole is formed by stamping, and water can enter the interior of the lamp body through the hanging hole. There is also a waterproof structure of a sign light on the market: an independently set hanging plate with a hanging hole is provided on the base shell, and mutually matching riveted positions are formed by stamping on the hanging plate and the base shell. The hanging hole and the base shell are suspended, and the riveted position on the base shell is a sealing structure, thereby preventing water vapor from entering the interior of the lamp body through the hanging hole. The structure has many components, complex processing, cumbersome assembly steps, and extremely high cost. Moreover, whether it is when stamping the riveted position or performing the riveting process, it is very easy to penetrate the base shell, causing the product to be scrapped, and the riveted hanging plate is easy to fall off, thereby causing product damage.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present disclosure will be more comprehensive and complete and the concepts of the example embodiments will be fully conveyed to those skilled in the art. The accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0030] The technical solution of the embodiment of the present application is briefly described below:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a waterproof sign lamp structure comprises: a cover 1, with a sign hole 11 on the surface; a bottom shell 2, which covers the cover 1 and has a light-emitting area 3 in the middle that matches the position of the sign hole 11; a waterproof groove 4, which is formed around the light-emitting area 3; and a mounting area 5, which is arranged on the bottom shell 2 and is arranged outside the range surrounded by the waterproof groove 4, and a mounting structure 6 is arranged on the mounting area 5. By arranging the light-emitting area 3 and the mounting area 5 on the bottom shell 2, and the mounting area 5 and the light-emitting area 3 are separated by the waterproof groove 4, when water enters the interior of the lamp body through the mounting structure 6, the water cannot enter the light-emitting area 3 due to the blocking of the waterproof groove 4, thereby protecting the light-emitting accessories in the light-emitting area 3, so that the product has a waterproof function, and the service life of the lamp is guaranteed. In addition, the structure is extremely simple, the number of components is small, and the product cost is greatly saved.

[0032] The bottom shell 2 is provided with an upwardly protruding support portion 41, which is formed around the light-emitting area 3, and the support portion 41 is in contact with the inner surface of the cover 1, and the waterproof groove 4 is arranged in the support portion 41. Since the mounting area 5 is provided with a mounting structure 6, and the mounting structure 6 requires the inside of the mounting area 5 to be suspended before use, and the inside of the light-emitting area 3 needs to be provided with a circuit board 32 and a light guide plate 31 to light up the logo hole 11, the inside of the light-emitting area 3 also needs to be suspended, and the protruding support portion 41 can make space between the surface of the light-emitting area 3 and the surface of the mounting area 5 and the inner surface of the cover 1. After the cover 1 and the bottom shell 2 are assembled with each other, the inside of the mounting area 5 is suspended, and the mounting area 5 is arranged on both sides of the light-emitting area 3, so that the user can use the mounting structure 6 for installation.

[0033] The light guide plate 31 is provided in the light emitting area 3. Since the thickness of the light guide plate 31 is relatively thin, in order to prevent the light guide plate 31 from moving, the height of the light emitting area 3 should be adapted to the thickness of the light guide plate 31. Therefore, the height of the portion of the light emitting area 3 where the light guide plate 31 is provided is smaller than the height of the mounting area 5. The light emitting area 3 is provided with an inwardly recessed plate groove 33 and a wire outlet groove 34. The plate groove 34 is provided with a circuit board 32. The wire outlet groove 34 is provided with a wire outlet hole 35. The wire outlet groove 34 is filled with waterproof glue; this structure can prevent water from entering the interior of the lamp body through the wire outlet hole 35.

[0034] The mounting structure 6 includes a snap-on portion 61 arranged on the back of the bottom shell and a bracket 62 arranged on the snap-on portion 61. A recessed portion 621 is provided on the bracket 62, and the position of the recessed portion 621 is adapted to the position of the plate groove 33. In order to cater to the market, the thickness of existing lamp bodies is relatively thin, and the plate groove 33 protruding from the back of the bottom shell 2 will make it impossible to install the bracket 62, while the recessed portion 621 enables the bracket 62 to be smoothly installed on the bottom shell 2.

[0035] The mounting structure 6 includes: a) a stamped hanging hole 63; and / or, b) a stamped buckle portion 61 and a bracket 62 disposed on the buckle portion 61; and / or, c) a wall nail hole 64 disposed on the surface cover 1 and the bottom shell 2 and penetrating the surface cover 1 and the bottom shell 2, the wall nail hole 64 penetrating the buckle portion 61. This structure can provide users with a variety of installation methods, so that the lamp can adapt to various installation environments.

[0036] The bottom shell 2 is covered with the face cover 1 through a snap-fit ​​mechanism, and the installation area 5 is arranged between the waterproof groove 4 and the snap-fit ​​mechanism; the snap-fit ​​mechanism includes a snap-fit ​​edge 21 formed along the periphery of the bottom shell 2, and the snap-fit ​​edges 21 at the upper and lower ends of the bottom shell 2 are connected to the support portion 41, and the snap-fit ​​edges 21, the support portion 41 and the inner surface of the face cover 1 are mutually abutted, and the installation area 5 is arranged between the waterproof groove 4 and the snap-fit ​​edges 21 at the left and right ends of the bottom shell 2. The snap-fit ​​mechanism enables the bottom shell 2 to be firmly assembled on the face cover 1, and when water enters the lamp body from the edge of the bottom shell 2, the waterproof groove 4 can block the water vapor, so that the water vapor cannot enter the light-emitting area 3, so that the product has a waterproof function, and the service life of the lamp is guaranteed, and the structure is extremely simple, with few components, which greatly saves product costs.

[0037] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
