AI Technical Summary
The glass cover of existing fire alarms cannot be reused and is prone to false alarms due to children's curiosity. The lack of a limiting structure also leads to frequent false alarms.
An integrated explosion-proof housing for the fire alarm was designed, comprising a flip-up glass cover, a locking rack, an unlocking lever, and an elastic element. The glass cover is locked by a toothed step, and the unlocking lever drives the locking rack to disengage from the step to open the cover and trigger the alarm. The elastic element enables automatic reset, and the sealing gasket improves the airtightness.
The glass cover is reusable, preventing false alarms, improving sealing and ease of use, and avoiding false alarms caused by misoperation.

[0018] Below we combine the explosion -proof shell of one -piece fire alarm of the utility model described in the attached diagram and make further explanation.
[0019] It needs to be explained that, all directionality instructions such as upper, lower, left, right, front, back in the embodiment of the application only are used to explain the relative position relationship, movement condition etc. between each component in a certain specific posture such as the shown in the attached diagram, if the specific posture changes, then the directionality instruction also changes accordingly.
[0020] Refer to the attached Figures 1-5As shown in the embodiment, the explosion-proof shell of the integrated fire alarm includes an explosion-proof shell body 1; characterized in that the explosion-proof shell body 1 is reversibly provided with a glass cover 2; the glass cover 2 is provided with a locking rack 201, and the locking rack 201 is connected with an unlocking rod 202 for unlocking the locking rack 201 and an elastic element 203 for pushing the locking rack 201 back to its original position; the explosion-proof shell body 1 is further provided with a plurality of toothed steps 101 for locking the locking rack 201; the toothed steps 101 on the explosion-proof shell body 1 are used to lock the locking rack 201 on the glass cover 2, and when unlocking is needed, the unlocking rod 202 is pulled to drive the locking rack 201 to move away from the toothed steps 101, so that the glass cover 2 can be opened for alarm, thereby facilitating the locking and opening of the glass cover 2, preventing the glass cover 2 from being always in an open state and causing false alarms, and allowing repeated use.
[0021] Refer to the accompanying drawings Figures 4-5 As shown in the embodiment, the glass cover 2 is provided with a mounting groove 204 for facilitating the sliding of the locking rack 201; the elastic element 203 is sleeved on the unlocking rod 202; one end of the elastic element 203 is connected with the locking rack 201, and the other end is connected with the side wall of the mounting groove 204; the mounting groove 204 is further provided with a positioning surface 205 for positioning the locking rack 201 when it is reset; the elastic element 203 can automatically reset the locking rack 201 by utilizing its own elasticity, thereby facilitating the fixation of the glass cover 2 and the explosion-proof shell body 1 again; the positioning surface 205 can position the reset position of the locking rack 201, thereby improving the accuracy of the locking of the locking rack 201 and the toothed steps 101 on the explosion-proof shell body 1.
