Description

Technical Field

[0001] This utility model belongs to the technical field of sound and light alarm devices, and specifically relates to a sound and light alarm device. Background Technology

[0002] The audible and visual alarm mainly consists of a sensing system, a control unit, a sound generating device, and a light signaling device. The sensing system connects to various sensors and transmits a signal to the control unit when an abnormal situation is detected. The control unit then issues a trigger command to activate the sound and light signaling devices, emitting a high-decibel alarm sound and a flashing light signal.

[0003] The speakers on existing audible and visual alarms are generally fixed, which limits the sound's propagation range to a small area when the alarm is activated, making it difficult to propagate over a large area and thus reducing the alarm's effectiveness.

[0004] Therefore, an audible and visual alarm was designed to overcome the aforementioned technical shortcomings. Utility Model Content

[0026] This specific embodiment is an audible and visual alarm device, the structural diagram of which is shown below. Figures 1-7 As shown, the device includes a housing 1, an alarm light 2 installed on the top surface of the housing 1, a mounting plate 4 located near the left side of the top surface of the housing 1, the mounting plate 4 being U-shaped, a speaker 3 rotatably connected to the inner side of the mounting plate 4, an annular shell 5 fixedly connected to the top surface of the inner cavity of the housing 1, a transmission assembly located inside the annular shell 5, and a swing assembly located inside the annular shell 5.

[0027] The components of the audible and visual alarm are located inside the housing 1. Since the audible and visual alarm, the speaker 3, and the alarm light 2 are all existing mature technologies, their principles and structures will not be described in detail in this solution.

[0028] like Figure 2 and Figure 4 As shown, the transmission assembly includes a base plate 6 fixedly connected to the inner side of the annular shell 5. A motor 7 is fixedly connected to the top surface of the base plate 6. A rotating shaft 8 is fixedly connected to the output shaft of the motor 7. The top end of the rotating shaft 8 passes through the housing 1 and is fixedly connected to the mounting plate 4. The rotating shaft 8 is rotatably connected to the housing 1. The transmission assembly can drive the speaker 3 to rotate, providing power to the speaker 3. In addition, the motor 7 can be a motor, micro motor, or other drive device.

[0029] like Figure 2 and Figure 4 As shown, the swing assembly includes a connecting plate 9 movably connected to the side wall of the speaker 3. The connecting plate 9 is L-shaped. Two annular plates 11 are fixedly connected to the inner wall of the annular shell 5. An annular groove 10 is opened on the top surface of the cabinet 1. The annular groove 10 communicates with the inner cavity of the annular shell 5. The connecting plate 9 passes through the annular groove 10 and extends to the space between the two annular plates 11. Several arc-shaped protrusions 12 are fixedly connected to the side walls of the two annular plates 11 on opposite sides.

[0030] The speaker 3 is equipped with a swinging component, which allows it to swing up and down while rotating, thereby expanding the range of the alarm sound and enabling users to hear the alarm sound in time and take appropriate protective measures.

[0031] like Figure 5 As shown, a movable wheel 13 is rotatably connected to the side wall of the connecting plate 9 near the arc-shaped protrusion 12, and the movable wheel 13 abuts against the arc-shaped protrusion 12. The gap between the two arc-shaped protrusions 12 is wavy. Utilizing the wavy structure formed between the arc-shaped protrusions 12, the connecting plate 9 rotates between the two annular plates 11 via the movable wheel 13. When the movable wheel 13 contacts the arc-shaped protrusion 12, it begins to swing. The movable wheel 13 can reduce the friction between the connecting plate 9 and the arc-shaped protrusion 12.

[0032] like Figure 4As shown, an annular block 14 is fixedly connected to the inner wall of the annular shell 5, and a groove 15 is provided on the side wall of the connecting plate 9. The annular block 14 is adapted to the groove 15. When the connecting plate 9 rotates, the groove 15 can be used to limit and assist the connection plate 9. During the up-and-down reciprocating movement of the connecting plate 9, it can fit against the annular block 14 to ensure the stability of the connecting plate 9.

[0033] like Figure 7 As shown, two fixing plates 16 are fixedly connected to the side wall of the speaker 3. Each fixing plate 16 has an elongated hole 18 on its side wall. Two round shafts 17 are fixedly connected to the side wall of the connecting plate 9 near its top. The round shafts 17 are adapted to fit the elongated holes 18. During the lifting and lowering process, the connecting plate 9 causes the speaker 3 to swing. The swing point is at the axis of connection with the mounting plate 4. To prevent interference between the linear motion of the connecting plate 9 and the arcuate motion of the speaker 3 during the swing, the cooperation of the elongated holes 18 and the round shafts 17 can eliminate interference, thereby stabilizing its swing.

[0034] Working principle: When the speaker 3 starts to sound the alarm, the alarm light 2 lights up simultaneously. At this time, the motor 7 is started. The output shaft of the motor 7 drives the speaker 3 to rotate through the rotating shaft 8, so that the speaker 3 can broadcast 360°.

[0035] At the same time, as the speaker 3 rotates, it drives the connecting plate 9 to rotate. The connecting plate 9 drives the movable wheel 13 to rotate between the two annular blocks 14. By using the arc-shaped protrusion 12 to form a wave gap, the speaker 3 can swing up and down, further improving the broadcast range of the speaker 3.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
