Description

Technical Field

[0001] This utility model relates to the field of buzzer technology, specifically an explosion-proof buzzer. Background Technology

[0002] Explosion-proof buzzers, as electronic sound devices, emit high-frequency buzzing sounds and have a wide range of important functions. They can serve as reminders, prompts, and alarms in various fields such as traffic safety, industrial automation, home appliances, and medical equipment. Their application not only helps prevent accidents but also improves the efficiency of life and work. Existing buzzers require holes to be drilled on their surface to increase the diffusion of the sound. However, when smoke detectors are triggered in the installation environment, fire-fighting water sprayed from the sprinkler can easily splash into the buzzer through the sound hole, causing a short circuit. A common solution is to install the sound hole at the bottom of the buzzer, which limits the installation location and prevents it from being installed on walls or ceilings, thus reducing the buzzer's applicability.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: an explosion-proof buzzer, including a mounting base 1 and support plates 2 fixed on the left and right sides of the upper surface of the mounting base 1. A buzzer housing 3 is provided on the inner side of the support plate 2. Multiple sets of sound outlet holes 301 are opened on the lower surface of the buzzer housing 3. A rectangular sleeve 4 is inserted into the top of the outer surface of the buzzer housing 3. Rectangular locking rods 5 are slidably inserted into the left and right sides of the inner wall of the rectangular sleeve 4. Rectangular locking holes 201 adapted to the rectangular locking rods 5 are opened on the inner side of the support plate 2. A pressing button 6 is fixedly connected to the outer end of the rectangular locking rod 5. The rectangular sleeve 4... A spring 9 is installed on the inner wall. The spring 9, rectangular sleeve 4, rectangular locking rod 5, pressing button 6 and rectangular locking hole 201 work together to allow the operator to press the pressing button 6 inward, causing the rectangular locking rod 5 to retract into the rectangular sleeve 4. Then, the buzzer housing 3 is rotated, thereby changing the position of the buzzer housing 3 relative to the mounting base 1. This ensures that the sound outlet 301 of the buzzer is vertically downward in various installation positions, avoiding the probability of fire sprinkler water entering the buzzer housing 3 through the sound outlet 301 and reducing the risk of short circuits in the internal electrical components of the buzzer.

[0023] In this utility model, in order to facilitate the installation of the rectangular sleeve 4 on the buzzer housing 3, a fixing plate 7 is fixedly connected to the right side of the outer surface of the rectangular sleeve 4. Fixing bolts 8 are inserted into the four corners of the right side of the fixing plate 7. The fixing bolts 8 are fixedly connected to the outer surface of the buzzer housing 3, so that the assembly worker can insert the rectangular sleeve 4 from the right side of the buzzer housing 3, and then fix the fixing plate 7 to the buzzer housing 3 by the fixing bolts 8.

[0024] In this utility model, in order to further facilitate the installation of the device, bolt holes 101 are provided at the four corners of the upper surface of the mounting base 1. Mounting bolts 10 are inserted into the inner wall of the bolt holes 101, so that the workers can install the device through the mounting bolts 10, thereby further facilitating the installation of the device.

[0025] In this invention, to prevent the rectangular locking rod 5 from sliding out of the rectangular sleeve 4, limiting blocks 501 are fixedly connected to both the upper and lower surfaces of the rectangular locking rod 5. A limiting groove 401 adapted to the limiting block 501 is provided on the outer surface of the rectangular sleeve 4. Through the cooperation of the limiting block 501 and the limiting groove 401, the rectangular locking rod 5 is limited, thus preventing it from sliding out of the rectangular sleeve 4.

[0026] In this invention, in order to further enhance the stability of the movement of the rectangular locking rod 5, two sets of rectangular slide bars are fixedly connected to the inner walls of the front and rear sides of the rectangular sleeve 4. A rectangular slide groove adapted to the rectangular slide bar is opened on the outer surface of the rectangular locking rod 5. The stability of the movement of the rectangular locking rod 5 is further enhanced by the cooperation between the rectangular slide bar and the rectangular slide groove.

[0027] In this utility model, in order to further enhance the stability of the support plate 2, two sets of reinforcing ribs are fixedly connected to the outer side of the support plate 2. The lower surface of the reinforcing ribs is fixedly connected to the upper surface of the mounting base 1, so that the reinforcing ribs play a stable supporting role for the support plate 2, thereby further enhancing the stability of the support plate 2.

[0028] In use, by pressing the button 6 inward with the mounting bolt, the rectangular locking rod 5 retracts into the rectangular sleeve 4, the spring 9 is compressed, and the button 6 enters the rectangular locking hole 201. Rotate the buzzer housing 3 and select the orientation of the buzzer housing 3 according to the specific installation situation. If it is installed on the top of the cabinet, the sound hole 301 is oriented towards the mounting base 1. If it is installed on the wall, the buzzer housing 3 is perpendicular to the support plate 2. If it is installed on the ceiling, the sound hole 301 is away from the mounting base 1. After selecting the installation position, release the button 6, the spring 9 returns to its original state, the rectangular locking rod 5 is inserted into the rectangular locking hole 201, and the buzzer housing 3 is fixed.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
