A corrosion-resistant buzzer Technical Field

[0001] This utility model relates to the field of buzzer technology, specifically a corrosion-resistant buzzer. Background Technology

[0002] As is well known, a corrosion-resistant buzzer is a sound-generating device that can function normally in corrosive environments, and its performance and structure are not affected by corrosion. Similar in function to a regular buzzer, it emits sound signals, but special measures are taken in its design and manufacturing to give it the ability to resist the erosion of various corrosive substances (such as acids, alkalis, salt solutions, as well as moisture and chemical gases). It is widely used in fields prone to corrosive environments, such as chemical, marine, food processing, and pharmaceutical production.

[0003] Existing corrosion-resistant buzzers typically have through-slots at the wires to allow the wires to extend from the casing. However, the size of these through-slots is usually larger than the wires, making it easy for external moisture to enter the casing and potentially damage the electronic components inside. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a corrosion-resistant buzzer.

The mounting block is disposed on the body. The sealing mechanism includes a ring, a frame, a square block, a rubber block, a connecting block, a first bolt, a fixing block, and a second bolt. The ring is sleeved on the outer wall of the body and is fixedly connected to the outer wall of the body. One end of the square block is connected to the rubber block, and the other end of the square block contacts the frame. One end of the connecting block is connected to the frame. The other end of the connecting block contacts the top of the block. The connecting block is connected to the block by the first bolt. The frame, the block, and the inner wall of the rubber block form a circle that matches the outer wall of the main body. The frame is fitted onto the outer wall of the main body. The bottom of the frame, the bottom of the block, and the bottom of the rubber block contact the top of the ring. The fixing block is disposed on the outer wall of the frame. The fixing block is connected to the ring by the second bolt. A through groove is provided on the main body. A circular hole is provided on the rubber block. One end of the wire passes through the through groove and the circular hole in sequence.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a corrosion-resistant buzzer with the following advantages:

[0015] This corrosion-resistant buzzer features a unique and effective sealing mechanism. Through its ingenious design, this mechanism provides a comprehensive seal to the through-slot on the body, facilitating the extension of the wire.

[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 refer to Figures 1-4. A corrosion-resistant buzzer includes a body 1, a mounting block 2, a wire 12, and a sealing mechanism 3. The mounting block 2 is disposed on the body 1. The sealing mechanism 3 includes a ring 4, a frame 5, a square block 6, a rubber block 7, a connecting block 8, a first bolt 9, a fixing block 10, and a second bolt 11. The ring 4 is sleeved on the outer wall of the body 1 and is fixedly connected to the outer wall of the body 1. One end of the square block 6 is connected to the rubber block 7, and the other end of the square block 6 contacts the frame 5. One end of the connecting block 8 is connected to the frame 5, and the other end of the connecting block 8 is connected to the frame 5. The top of the block 6 is in contact with the connecting block 8, which is connected to the block 6 by the first bolt 9. The inner wall of the frame 5, the block 6, and the rubber block 7 forms a circle that matches the outer wall of the body 1. The frame 5 is fitted onto the outer wall of the body 1. The bottom of the frame 5, the bottom of the block 6, and the bottom of the rubber block 7 are in contact with the top of the ring 4. The fixing block 10 is disposed on the outer wall of the frame 5 and is connected to the ring 4 by the second bolt 11. A through groove is provided on the body 1, and a round hole is provided on the rubber block 7. One end of the wire 12 passes through the through groove and the round hole in sequence.

[0023] This structure achieves a good sealing effect by setting a sealing mechanism 3. After the wire 12 extends out of the through groove of the body 1, it will pass through the rubber block 7 of the sealing mechanism 3. The through hole of the rubber block 7 is smaller than the wire 12. Because it has flexibility and deformation ability, after the wire 12 is forcefully passed through the rubber block 7, the rubber block 7 can tightly wrap the outer wall of the wire 12 and fit tightly with the outer wall of the body 1 without gaps, effectively preventing external moisture from entering the interior of the body 1 through the through groove. In addition, with the help of the mounting block 2 and the external specified bolts, the body 1 can be installed in a suitable position.

[0024] After prolonged use, rubber block 7 experiences elastic fatigue due to repeated stretching, leading to a decrease in sealing performance. When rubber block 7 needs to be replaced, refer to Figure 1. First, use an external screwdriver to loosen the first bolt 9 to separate it from block 6. Then, slowly pull rubber block 7 to separate it and block 6 from frame 5. During this process, pull carefully to avoid excessive force that could damage or break wire 12. After wire 12 is successfully separated from rubber block 7, replace it with a new rubber block. New parts can be obtained from the manufacturer and will not be described in detail here. During installation, forcefully pass one end of wire 12 through the through hole of rubber block 7. To replace frame 5, similarly use an external screwdriver to loosen the second bolt 11 to separate it from fixing block 10 and ring 4. Then pull frame 5 to separate it from body 1, thus completing the replacement of frame 5.

[0025] To improve the installation effect, in this embodiment, two mounting blocks 2 are provided, symmetrically arranged, and rubber shock-absorbing pads can be added between the mounting blocks 2 and the mounting surface. Rubber shock-absorbing pads have good elasticity and shock absorption performance, effectively absorbing the energy generated by equipment vibration and external impact, reducing the shaking and displacement of the buzzer.

[0026] To improve stability, in this embodiment, the fixing block 10 is provided in several parts, and the second bolt 11 is provided in several parts.

[0027] The first bolt 9 and the second bolt 11 are prone to rusting after long-term use. In order to solve this problem, in this embodiment, the first bolt 9 and the second bolt 11 are made of stainless steel.

[0028] To improve the connection effect, in this embodiment, the fixing block 10 is fixedly connected to the frame 5.

[0029] To improve the strength of the ring 4, the ring 4 is made of aluminum alloy.

[0030] In this structure, the body 1 is made of polycarbonate (PC), a corrosion-resistant engineering plastic. PC offers excellent mechanical properties, transparency, and chemical resistance. Chemical additives, such as stress crack inhibitors, can be added to polycarbonate to enhance its stability in highly corrosive environments. Alternatively, a higher-grade corrosion-resistant engineering plastic, such as polyetheretherketone (PEEK), can be used. PEEK possesses excellent chemical stability, high-temperature resistance, and mechanical properties, better adapting to harsh corrosive environments and effectively ensuring the structural stability and reliable performance of the buzzer. The internal diaphragm of the body 1 can be made of a composite material of fluororubber and nitrile rubber. Fluororubber has superior chemical corrosion resistance and high-temperature resistance. When combined with nitrile rubber, it retains some of the advantages of nitrile rubber while significantly improving the diaphragm's corrosion resistance in special chemical media. Furthermore, all metal parts are galvanized. The protective film formed by the zinc plating on the metal surface provides electrochemical protection, further enhancing the buzzer's corrosion resistance.

[0031] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in this field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and wiring layout will not be explained in detail here.

[0032] 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.
