Referring to fig. 1, 2 and 3, an alarm 10 for fire fighting includes a fixed housing 100 and a movable housing 200 rotatably disposed on the fixed housing 100. In the present embodiment, the fixed housing 100 has a square housing structure, and the movable housing 200 has a square housing structure. Further, a through hole is formed in the movable housing 200, and the through hole is covered with a transparent material 201 (as shown in fig. 1). In the present embodiment, the transparent material 201 is a thin film structure. In other embodiments, the transparent material 201 may also be a glass structure. For example, when a fire occurs, the transparent material 201 can be broken, and then electronic components inside the housing are triggered, and the electronic components are impacted, so that corresponding alarm information is sent out.
As shown in fig. 3, the alarm 10 for fire fighting further includes a locking mechanism 300, and the locking mechanism 300 is installed in the stationary housing 100.
As shown in fig. 4, the locking mechanism 300 includes: a support seat 310, a sliding rod 320, a tension spring 330, a rotating rod 340, a torsion spring 350 and an unlocking rod 360.
As shown in fig. 4, the sliding rod 320 is slidably disposed on the supporting seat 310, one end of the tension spring 330 is connected to the supporting seat 310, and the other end of the tension spring 330 is connected to the sliding rod 320.
As shown in fig. 4, the rotating rod 340 is rotatably disposed on the supporting seat 310, one end of the torsion spring 350 is connected to the supporting seat 310, and the other end of the torsion spring 350 is connected to the rotating rod 340.
As shown in fig. 4, the unlocking lever 360 is rotatably disposed on the support base 310, one end of the unlocking lever 360 abuts against or separates from the sliding lever 320, and the other end of the unlocking lever 360 abuts against or separates from the rotating lever 340.
As shown in fig. 4, the sliding rod 320 is provided with a first forced resetting block 321, the rotating rod 340 is provided with a second forced resetting block 341, the first forced resetting block 321 is provided with a first forced resetting inclined surface 322, the second forced resetting block 341 is provided with a second forced resetting inclined surface 342, and the first forced resetting inclined surface 322 and the second forced resetting inclined surface 342 abut against or separate from each other. In this embodiment, the first forced resetting block 321 has an elastic rubber block structure, and the second forced resetting block 341 has an elastic rubber block structure.
The locking mechanism 300 further includes a push-pull slider 370 (shown in fig. 2 and 3) located outside the fixed housing 100, wherein the push-pull slider 370 is inserted through the fixed housing 100 and connected to the sliding rod 320. Further, the push-pull slider 370 is provided with anti-slip threads 371 (as shown in fig. 2), so that friction can be increased, and a better anti-slip effect can be achieved.
As shown in fig. 4, the rotating rod 340 is provided with a fixed latch 343, and the movable housing 200 is provided with a movable latch 210 engaged with the fixed latch 343.
The operation of the above-described fire alarm 10 will now be explained:
under normal conditions, the fixed housing 100 is fixed on a wall, the movable housing 200 covers the fixed housing 100, at this time, the movable latch 210 on the movable housing 200 and the fixed latch 343 on the rotating rod 340 are latched together, so that the movable housing 200 is pulled by external force, and the movable housing 200 cannot be opened from the fixed housing 100;
when daily security check maintenance needs to be performed on the alarm 10 for fire fighting, the movable shell 200 needs to be opened from the fixed shell 100, so that electronic components in the fixed shell 100 are in an open state, and security check maintenance of workers is facilitated;
specifically, the push-pull slider 370 is pushed by an external force, so that the push-pull slider 370 moves to one side, and the push-pull slider 370 further drives the sliding rod 320 to slide along the supporting seat 310, in the process that the sliding rod 320 slides along the supporting seat 310, on one hand, the first forced reset block 321 on the sliding rod 320 can temporarily keep away from the second forced reset block 341, so as to reserve a space for the rotation of the rotating rod 340, on the other hand, the sliding rod 320 in sliding can touch one end of the unlocking rod 360, so that the unlocking rod 360 rotates, the other end of the rotating unlocking rod 360 touches the rotating rod 340, and then, the rotating rod 340 can rotate by an angle; when the rotating rod 340 rotates by an angle, the fixed latch 343 on the rotating rod 340 is separated from the movable latch 210 on the movable housing 200, so that the movable housing 200 can be opened from the fixed housing 100;
when external force is not applied to the push-pull slider 370 any more, the sliding rod 320 moves in the opposite direction and resets under the action of the tension spring 330, the sliding rod 320 no longer touches the unlocking lever 360, the unlocking lever 360 no longer applies acting force to the rotating rod 340, and thus the rotating rod 340 also resets under the action of the elastic restoring force of the torsion spring 350; it should be particularly noted that, in this process, the moving sliding rod 320 applies an acting force to the second forced resetting inclined surface 342 of the second forced resetting block 341 through the first forced resetting inclined surface 322 of the first forced resetting block 321 thereon, so as to urge the rotating rod 340 to be forcibly reset, thereby avoiding the situation that the torsion spring 350 cannot drive the rotating rod 340 to be accurately reset due to insufficient elastic force in the long-term use process;
when the staff finishes the security inspection and maintenance of the electronic components in the fixed housing 100, the movable housing 200 needs to be covered on the fixed housing 100 again, and at this time, as long as a pushing force is applied to the movable housing 200, the movable latch 210 on the movable housing 200 can be clamped on the fixed latch 343 of the rotating rod 340 again; it should be particularly noted that, in the process that the movable latch 210 is clamped in the fixed latch 343, since the first forced resetting block 321 and the second forced resetting block 341 are both made of elastic rubber blocks, the first forced resetting block 321 and the second forced resetting block 341 are slightly deformed when being stressed, so that the rotating rod 340 can rotate at a small angle, and the movable latch 210 can be smoothly clamped in the fixed latch 343, and when the movable latch 210 is clamped in place with the fixed latch 343, the first forced resetting block 321 and the second forced resetting block 341 can be deformed again.
The alarm for fire fighting provided by the invention has the advantages that the shell is not easy to detach under a general condition, and the components in the shell are prevented from being damaged, so that the shell can be detached smoothly only by professional security inspection maintenance personnel.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
