[0020] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0021] As Figures 1 - 3As shown, the indoor fire hydrant anti-theft alarm device includes a placement cylinder 1. The top of the placement cylinder 1 is not enclosed. A bracket 2 is fixedly connected to the bottom surface of the placement cylinder 1. An activity plate 3 is arranged in the inner cavity of the placement cylinder 1. A control component is arranged on the bottom surface of the activity plate 3. A groove 4 is opened on the top surface of the activity plate 3. A password controller 5 is arranged in the groove 4. A housing 11 is fixedly connected to the bottom surface of the placement cylinder 1. A connecting plate 12 is fixedly installed on the inner wall of the housing 11. A buzzer 13 is installed on the side wall of the connecting plate 12. A number of through holes 14 are opened on the side wall of the housing 11.

[0022] Among them, the general method of using the password controller 5 to control the buzzer 13 is as follows:

[0023] Program the password controller 5: Ensure that the password controller 5 has been programmed, including the code for password input and verification;

[0024] Set the stop password: In the code, specify a specific password to stop the buzzer 13, and this password is different from the password that triggers the buzzer 13;

[0025] Verify the input password: After the password is input, verify whether the input password matches the stop password;

[0026] Stop the buzzer 13: If the input password matches the stop password, program the password controller 5 to stop the triggering of the buzzer 13.

[0027] As Figure 3 shown, the control component includes a vertical rod 6 fixedly connected to the bottom surface of the activity plate 3. The vertical rod 6 passes through the placement cylinder 1 and is movably connected thereto. The bottom end of the vertical rod 6 is fixedly connected with a horizontal plate 7. A spring 8 is assembled on the side wall of the vertical rod 6. Trigger contacts 9 are respectively fixedly connected to the top surface of the horizontal plate 7 and the bottom surface of the placement cylinder 1. Disconnecting contacts 10 are respectively fixedly connected to the bottom surface of the horizontal plate 7 and the bottom surface of the inner cavity of the housing 11.

[0028] Among them, the trigger contacts 9 and the disconnecting contacts 10 can be replaced by switches. Their control method is mainly controlled by the gravity of the fire extinguisher and the resilience of the spring 8, and the control states of the trigger contacts 9 and the disconnecting contacts 10 can be realized.

[0029] As Figure 1 and Figure 2 shown, a rubber ring 15 is fixedly connected to the inner wall of the placement cylinder 1. The cross-section of the rubber ring 15 is trapezoidal. The rubber ring 15 is mainly made of elastic material. When the fire extinguisher is placed inside the placement cylinder 1, the friction between them can be increased, ensuring the stability and firmness of the fire extinguisher, and at the same time avoiding the problem of shaking and tipping.

[0030] As Figure 1As shown in the figure, a protective film 16 is fixedly connected to the upper side of the password controller 5 on the side wall of the groove 4. The protective film 16 is made of a transparent film, which can play a role in dust and water protection for the password controller 5 on the one hand, and does not affect the operation of the password controller 5 on the other hand.

[0031] As Figure 2 shown in the figure, two limiting rods 17 are fixedly connected to the bottom surface of the movable plate 3, and the bottom ends of the limiting rods 17 penetrate through the placing cylinder 1 and are movably connected thereto. The limiting rods 17 can be used to limit the movable plate 3, so that the movable plate 3 can be in the same position during lifting and lowering, thereby improving the stability of the movable plate 3.

[0032] As Figure 2 shown in the figure, a battery box 18 is provided near the rear side in the inner cavity of the housing 11. And a battery is assembled inside the battery box 18. The battery is electrically connected to the buzzer 13 and the password controller 5, and can also be connected to an external power supply through a plug. By setting the battery, it is convenient to play a role in anti-theft warning even in a power outage state.

[0033] In addition, this solution is not only applicable to the inside of a fire hydrant, but also applicable to some outdoor places, factories, schools and other places.

[0034] The working principle of this utility model is as follows: When it is necessary to protect the fire extinguisher inside the fire hydrant, the fire extinguisher can be directly placed in the placing cylinder 1. The gravity of the fire extinguisher presses down the movable plate 3, and at the same time the spring 8 stretches, so that the movable plate 3 drives the two disconnected contacts 10 on both sides to contact through the vertical rod 6. At this time, the buzzer 13 is in a power-off state. If the fire extinguisher is taken out, the movable plate 3 rises under the restoring force of the spring 8. At this time, the trigger contact 9 is closed, and the buzzer 13 emits an alarm sound to achieve a warning effect. If it is a daily inspection, the staff can set the password and input it into the password controller 5 to turn off the alarm of the buzzer 13, effectively playing an anti-theft role for the fire extinguisher.

[0035] The above are only the preferred embodiments of this utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices and operation methods not specifically described and explained in this utility model are implemented according to the conventional means in the art without special description and limitation.
