Detailed Description
The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.
Examples
As shown in fig. 1 to 4, taking a fire display panel in a fire fighting device as an example, the fire display panel is a fire alarm display device that can be installed on a floor or an independent fire protection area, and is used for a fire alarm device in the floor or the independent fire protection area, when a host controller of a control center generates an alarm and transmits an alarm signal to the fire display panel in a fire area, the display panel displays the detector number of the alarm and related information and sends out an alarm sound, and the fire display panel is commonly used in various high-rise buildings for fire alarm and protection of life safety of people. The structure of the fire display disc is the structure of the base and the cover body. The fire display panel needs to lock the cover body and the base under a normal state.
In this embodiment, the fire display panel is provided with a bolt structure on the top of the side wall of the base, a stop block 2 matched with the bolt structure 1 for limiting and locking is arranged on the inner side of the cover body 14, an unlocking through hole 3 is formed in the cover body, and an unlocking needle 4 used for ejecting the bolt structure 1 through the unlocking through hole 3 to realize unlocking is arranged. The fastening structure of the fire display panel is the same as the conventional fastening form. The bulge on the cover body is aligned with the notch on the base and then buckled in a rotating mode, and meanwhile the lock tongue structure 1 and the stop block are locked in the rotating mode. When the unlocking is needed, the unlocking needle 4 is utilized to jack the spring bolt structure 1 through the unlocking through hole 3, the spring bolt structure withdraws from the baffle under the plastic elasticity of the spring bolt structure, and then the cover body is rotated to realize the separation of the base and the cover body.
