The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0041] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0042] Combine Figures 1 to 10 As shown, a buzzer for a machine positioning detection device includes a first shell 1, a second shell 2 and a buzzer assembly 3.

[0043] The second housing 2 is detachably disposed on one side of the first housing 1 ; the buzzer assembly 3 is disposed between the first housing 1 and the second housing 2 .

[0044] Among them, by connecting the first shell 1 and the second shell 2 in a detachable manner, the effect of easy disassembly is achieved, so that when the buzzer component 3 fails, the first shell 1 and the second shell 2 can be easily disassembled to complete the replacement of the buzzer component 3. This not only saves maintenance time, but also reduces the extra workload caused by replacing the entire machine, greatly improving the effect of repairing the buzzer.

[0045] Combine Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, a plurality of plug-in holes 11 are provided on the side opposite to the second shell 2, and a limiting hole 12 is provided on one side of the plug-in hole 11; a plug-in block 21 corresponding to the plug-in hole 11 is provided on the side opposite to the first shell 1, and a limiting block 22 is provided on one side of the plug-in block 21; the plug-in block 21 is embedded in the plug-in hole 11, and the limiting block 22 is embedded in the limiting hole 12.

[0046] Among them, by embedding the plug-in block 21 into the plug-in hole 11, the preliminary fixation between the second shell 2 and the first shell 1 can be achieved. The embedding of the limit block 22 into the limit hole 12 further strengthens this fixing effect, ensuring that the two shells will not easily loosen or fall off during use. The cooperation between each plug-in hole 11 and the corresponding plug-in block 21, as well as the cooperation between the limit hole 12 and the limit block 22, ensures the position accuracy of the second shell 2 relative to the first shell 1. When the buzzer assembly 3 needs to be replaced, it is only necessary to pull out the limit block 22 from the limit hole 12, and then remove the plug-in block 21 from the plug-in hole 11, and the two parts of the shell can be easily separated. This not only simplifies the maintenance process, but also reduces the cost and time consumption caused by replacing the entire device.

[0047] To further illustrate, both the retaining hole 12 and the retaining block 22 are triangular in structure, with distinct vertices and corners. This allows for precise positioning of the retaining block 22 when inserted into the retaining hole 12. This design ensures a more accurate positioning of the second housing 2 relative to the first housing 1, avoiding errors caused by positional deviations. The triangular structure provides significant constraints in all three directions, effectively constraining the position of the second housing 2 and preventing displacement in any direction.

[0048] Combine Figure 4 As shown, a limit assembly 13 is provided on one side of the plug hole 11. The limit assembly 13 includes a first spring 131 and a limit plate 132. One end of the first spring 131 is connected to a side wall of the plug hole 11, and the other end of the first spring 131 is connected to the limit plate 132. The limit plate 132 contacts the plug block 21.

[0049] Among them, the limit plate 132 is always close to the plug-in block 21 under the action of the spring force of the first spring 131, which can effectively prevent the plug-in block 21 from loosening or falling off due to vibration or other reasons during use. When disassembly is required, the second shell 2 needs to be manually pulled so that the second shell 2 drives the plug-in block 21, and the plug-in block 21 drives the limit block 22 to slide in the plug-in hole 11. When the plug-in block 21 drives the limit block 22 to slide in the plug-in hole 11, the plug-in block 21 will push the limit plate 132, so that the limit plate 132 applies a certain pressure to the first spring 131, and the first spring 131 is continuously in a compressed state until the limit block 22 is completely moved into the plug-in hole 11, and when the limit block 22 is no longer restricted by the limit hole 12, the separation between the second shell 2 and the first shell 1 can be completed.

[0050] Combine Figure 6 As shown, the plug-in block 21 is L-shaped, and an inclined chamfer 23 is provided on one side of the plug-in block 21. Under such a design, the plug-in block 21 is prevented from colliding with the limit plate 132 when the second shell 2 is fixedly installed on the first shell 1.

[0051] Combine Figure 2 As shown, disassembly openings 1A are respectively provided on both sides of the first shell 1 and the second shell 2, so that the first shell 1 and the second shell 2 can be easily disassembled and installed by the corresponding disassembly openings 1A.

[0052] Combine Figure 1 and Figure 2 As shown, a plurality of observation windows 1B are respectively provided on the first shell 1 and the second shell 2 , and transparent glass 1C is provided at the observation windows 1B.

[0053] The observation window 1B and the transparent glass 1C allow real-time monitoring of the working status of the internal buzzer assembly 3. This helps to promptly detect potential problems, such as abnormal vibration, heating, etc., so that measures can be taken quickly to deal with them.

[0054] Combine Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the buzzer assembly 3 includes a circuit board 31, a battery 32, a resistor 33, an LED light 34, and a buzzer body 35. The battery 32, resistor 33, LED light 34, and buzzer body 35 are disposed on the circuit board 31. The resistor 33, LED light 34, and buzzer body 35 are electrically connected to the battery 32 to form a complete circuit loop.

[0055] Specifically, the positive terminal of battery 32 is connected to VDD via PAD1. Resistors 33 are resistors R1 and R2. LED lights 34 are LED1 and LED2, with resistors R1 and R2 connected between LED1 and LED2, respectively. LEDs LED1 and LED2 are configured to illuminate when the circuit is closed. Buzzer J1 is configured to emit a sound when the circuit is closed. The VDD voltage range is 2V to 3V, and the maximum output power is 5V / 40mA.

[0056] Combine Figure 10 As shown, the working principle of the buzzer component 3 is as follows:

[0057] When the battery 32 is connected to the circuit, the circuit is closed and current begins to flow. The current starts from the positive pole of VDD. Part of the current flows to LED1 through resistor R1, and then flows to GND through LED1. Another part of the current flows to LED2 through resistor R2, and then flows to GND through LED2. LED1 and LED2 emit light when the circuit is closed, providing visual feedback. Another part of the current flows directly to the buzzer body 35J1, and then flows to GND through the buzzer body 35J1. The buzzer body 35 produces sound when current passes through, providing auditory feedback.

[0058] This design not only realizes the dual prompt functions of light and sound, but also protects the LED light through the current limiting resistors R1 and R2, ensuring the stability and reliability of the circuit.

[0059] Combine Figure 2 As shown, a through hole 311 is formed in the circuit board 31, to which a tension spring 4 is connected. One end of the tension spring 4 passes through the first and second housings 1 and 2 and extends to the outside to connect to a detection ball 5, which is located at one end of the first and second housings 1 and 2. A printed circuit board 6 is connected to one side of the circuit board 31, and a dry cell battery 7 is connected to one side of the printed circuit board 6. A conductive tube cover 8 is placed between the other ends of the first and second housings 1 and 2, and a second spring 9 is provided between the conductive tube cover 8 and the dry cell battery 7.

[0060] Among them, when the conductive tube cover 8 contacts the dry battery 7, the circuit is closed. When the detection ball 5 contacts a conductive object, the tension spring 4 is stretched, forming a closed switch S3. The current starts from the positive electrode of the dry battery 7, passes through PAD2 on the printed circuit board 6 to reach VDD, and passes through PAD1 on the circuit board 31 to reach VDD. Part of the current flows through the resistor R1 to the LED1 lamp, and then flows through the LED1 lamp to GND. Another part of the current flows through the resistor R2 to the LED2 lamp, and then flows through the LED2 lamp to GND. Another part of the current flows through the buzzer body 35J1, and then flows through the buzzer body 35J1 to GND. When the detection ball 5 contacts a conductive object, the tension spring 4 is stretched, forming a closed switch S3. After the circuit is closed, the LED lamp 34 lights up and the buzzer body 35J1 emits a sound.

[0061] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention.
