Description

Technical Field

[0001] The utility model relates to the technical field of emergency lights, in particular to an emergency light with replaceable indicating marks. Background Art

[0002] Most of the emergency signs on traditional emergency lights are fixed on the lampshade in an integrated manner when they leave the factory, which makes most of the existing emergency lights have low reusability and are only suitable for a designated emergency scene. If the emergency sign on the emergency light needs to be replaced so that the emergency light can be used in other emergency scenes, the entire lampshade needs to be removed and replaced, which is likely to cause material waste to a certain extent and has high replacement costs.

[0003] For this purpose, the Chinese utility model patent application with application number CN202121646497.6 (authorization announcement number: CN216145383U) discloses "An emergency light with a replaceable emergency indicator mark", which includes a translucent lampshade with a detachable emergency indicator mark and a shell with a light source assembly, wherein the emergency indicator mark is connected to the inner side wall of the translucent lampshade by gluing. The translucent lampshade cover is arranged above the shell and is sealed with the shell to form a light source cavity, the light source assembly is arranged in the light source cavity, and support plates for supporting the translucent lampshade are arranged on both ends of the shell, and the support plates are vertically inserted into the translucent lampshade and are connected to the inner side walls of both ends of the translucent lampshade. The emergency light can replace the emergency indicator mark on the emergency light at any time according to the required emergency scene, so that the emergency light can be flexibly adapted to different places.

[0004] However, the emergency light in the above patent application still has certain shortcomings. The emergency indicator label is connected to the inner wall of the light-transmitting lampshade by gluing. By gluing the emergency indicator label on the inner wall of the lampshade, the emergency indicator label may not be well placed on the lampshade. If it is not properly pasted, it is easy to cause the emergency indicator label to be deformed or damaged when it is torn off. In particular, the operating space on the inner wall of the lampshade is limited. The installation method of this indicator label gluing makes the installation process more cumbersome and the installation efficiency low.

[0005] Therefore, existing emergency lights still need further improvement. Utility Model Content

[0012] Generally speaking, the corresponding parts of the hidden buckle assembly can be fixed on the light guide plate and the logo sticker respectively, but this method is relatively cumbersome to process and has high production cost. In order to save costs, the light guide plate has a mounting hole that passes through the front and back, and the logo sticker is provided with a connecting hole. The hidden buckle assembly includes a first hidden buckle and a second hidden buckle that are located on the front and back sides of the light guide plate and can be buckled with each other. The first hidden buckle passes through the connecting hole of the logo sticker and the mounting hole of the light guide plate and is connected to the second hidden buckle. The above-mentioned first hidden buckle and second hidden buckle are both detachable parts independent of the light guide plate and the logo sticker. Therefore, when different logo stickers need to be replaced, the same set of hidden buckles can be used.

[0013] In order to achieve a secure connection between the logo sticker and the light guide plate, the first concealed buckle includes a first concealed buckle body and a convex column protruding from the first concealed buckle body, and the second concealed buckle includes a second concealed buckle body and a sleeve provided on the second concealed buckle body and having a bite opening, and the convex column can pass through the connecting hole of the logo sticker and the mounting hole of the light guide plate and be inserted into the bite opening of the sleeve.

[0014] In order to reduce the number of concealed buckle components and further reduce production costs, the light guide plate has a first side connected to the lamp housing and a second side away from the lamp housing, the lamp housing is also provided with a strip opening for the light guide plate to pass through, the identification sticker has a third side corresponding to the first side of the light guide plate and a fourth side corresponding to the second side of the light guide plate, the concealed buckle component is arranged adjacent to the second side of the light guide plate to fix the fourth side of the identification sticker relative to the light guide plate, and the third side of the identification sticker extends into the gap between the light guide plate and the side edge of the strip opening of the lamp housing.

[0015] In order to securely mount the light guide plate on the lamp housing, the first side edge of the light guide plate has a limit stop protruding to the side to limit the light guide plate from slipping out of the strip opening. The lamp housing also has a fixing seat for mounting the lamp board, which rests against the first side edge of the light guide plate.

[0016] In order to install the lamp board into the lamp housing and ensure the luminous brightness of the light guide plate, the lamp board is installed on the fixing seat, and the light source of the lamp board faces the first side of the light guide plate.

[0017] Generally, the light guide plate can extend horizontally to the side, or upward or downward from the lamp housing. Preferably, the light guide plate is arranged at the bottom of the lamp housing and extends downward from the bottom wall of the lamp housing, and the buckle assembly is arranged at the bottom edge of the light guide plate.

[0018] In order to achieve a secure fixation of the identification sticker, the concealed buckle components have at least two groups, and the concealed buckle components are sequentially spaced apart in the left-right direction.

[0019] In order to save the number of concealed buckle components and improve the aesthetics of the emergency light, the light guide plate is a square plate, and the concealed buckle components have two groups, and the two groups of concealed buckle components are respectively located at the left and right corners of the light guide plate.

[0020] Considering that emergency lights, especially suspended emergency lights, need to be provided with two identification stickers, in order to simplify the fixing structure of the identification stickers of the emergency lights, the identification stickers are provided with two pieces, and the two identification stickers are fixed on two opposite sides of the light guide plate by the same concealed buckle assembly.

[0021] Compared with the prior art, the advantages of the utility model are as follows: the identification sticker of the emergency light is fixed to the outer wall surface of the light guide plate of the lamp housing through a concealed buckle assembly. When the identification sticker needs to be installed or replaced, the identification sticker can be easily installed on the light guide plate or removed from the light guide plate, which greatly improves the installation efficiency of the emergency light.
