[0002] In the field of environmental monitoring, noise is one of the important pollution indicators. Its accurate detection is crucial for assessing environmental quality and ensuring the quality of life of residents. With the acceleration of urbanization and the frequent development of various industrial activities, environmental noise sources have become increasingly complex and diverse. In order to grasp the noise pollution situation in a timely and accurate manner, the demand for portable environmental noise detection devices is becoming increasingly urgent.
[0003] Existing handheld devices present extremely limited operating environments for inspectors in narrow passageways of old urban residential areas or in cramped ventilation shafts inside buildings. The switches and adjustment buttons of traditional devices are often located in conventional positions on the device body, without taking into account the limited hand movement in confined spaces. This makes it difficult for inspectors to accurately reach the buttons due to the difficulty in extending their hands flexibly. Therefore, improvements are needed to address these issues. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable environmental noise detection device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable environmental noise detection device, comprising a sensing ball, a support telescopic rod, a detector, and a connecting wire passing through the support telescopic rod and connecting the sensing ball. A second mounting component is provided on one side of the top surface of the detector, and an adapter connector is provided on the other side of the top surface of the detector. The adapter connector is plugged into one end of the connecting wire.
[0006] Preferably, the support telescopic rod is divided into a sleeve and an extension rod sleeved inside the sleeve. The top end of the extension rod is provided with an external threaded joint, and the sensing detection ball is provided with an internal threaded joint. The external threaded joint and the internal threaded joint are screwed together and fixed. A rubber pad is provided at the bottom end of the internal threaded joint.

[0008] Preferably, a rubber protrusion is provided at one end of the extension rod, and multiple fixing holes are equally spaced on the outer wall of the sleeve, with the rubber protrusion engaging in one of the fixing holes.
[0009] Preferably, the protective cover has two rectangular grooves on both sides, and the inner wall of the sliding mounting groove has two rectangular inserts corresponding to the two rectangular grooves on both sides. The sliding end of the sliding mounting groove has a chamfer, and the chamfer has a snap-fit opening.

[0010] Preferably, the extension rod is provided with a V-shaped mating groove, the inner wall of the sleeve is provided with a protrusion corresponding to the V-shaped mating groove, and the connecting wire is provided with an abutment block at the bottom end of the sleeve.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of the support telescopic rod and the sensor detection ball, makes it easy to extend the sensor detection ball into narrow spaces such as narrow passages in old urban communities and small ventilation shafts inside buildings for noise detection, which improves the convenience of detection. In addition, it can realize that the equipment does not need to be extended into narrow areas for detection, ensuring that the operator can accurately use the buttons.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Example: See Figure 1-5 This utility model discloses a portable environmental noise detection device, comprising a sensing ball 1, a supporting telescopic rod 2, a detector 3, and a connecting wire 4 passing through the supporting telescopic rod 2 and connecting to the sensing ball 1. A second mounting component is provided on one side of the top surface of the detector 3, and an adapter connector 5 is provided on the other side of the top surface of the detector 3. The adapter connector 5 is inserted into one end of the connecting wire 4. This structure enables effective connection between the sensing ball 1 and the detector 3, facilitating the transmission of detected noise signals to the detector 3 for processing. Simultaneously, the position of the sensing ball 1 can be flexibly adjusted, improving the flexibility and accuracy of the detection. The supporting telescopic rod 2 consists of a sleeve 13 and an extension rod 11 fitted inside the sleeve 13. An external threaded connector 9 is provided at the top of the extension rod 11, and an internal threaded connector 8 is provided on the sensing ball 1. The external threaded connector 9 and the internal threaded connector 8 are screwed together. A rubber pad 10 is provided at the bottom of the internal threaded connector 8. The telescopic structure allows for adjustment according to actual needs. The detection height and depth are suitable for different detection scenarios; the threaded connection ensures the stability of the connection between the sensor ball 1 and the support telescopic rod 2; the rubber pad 10 is made of rubber, which has good elasticity and sealing properties, and can play a buffering and sealing role, reducing external interference and improving detection accuracy. The second mounting component includes a sliding mounting groove opened on one side of the top surface of the detector 3. A protective cover plate 7 is slidably inserted into the sliding mounting groove. The detector 3 is provided with a direct connection detection head 6 at the protective cover plate 7. The direct connection detection head 6 is provided with a thread corresponding to the internal thread connector 8. The protective cover plate 7 can protect the direct connection detection head 6 and prevent it from being damaged or contaminated with dust when not in use. The setting of the direct connection detection head 6 makes it convenient to directly connect the sensor ball 1 to the detector 3 during daily handheld detection, which improves the convenience of use. The protective cover plate 7 is made of engineering plastic, which is lightweight and has a certain strength and corrosion resistance, and can effectively protect the direct connection detection head 6.
[0021] In this invention, a rubber protrusion 12 is provided at the bottom end of the extension rod 11. Multiple fixing holes are equidistantly provided on the outer wall of the sleeve 13. The rubber protrusion 12 is engaged in one of these fixing holes. This engaging structure facilitates adjustment of the length of the supporting telescopic rod 2 and, after adjustment, can fix the extension rod 11 in a suitable position, ensuring the stability of the length of the supporting telescopic rod 2, thus better adapting to different testing environments. The rubber protrusion 12 is made of natural rubber, and its good elasticity allows it to tightly engage in the fixing hole, ensuring the reliability of the telescopic adjustment. Two rectangular grooves are provided on both sides of the protective cover plate 7. Two rectangular inserts corresponding to the two rectangular grooves are provided on both sides of the inner wall of the sliding mounting groove. A chamfer is provided at the sliding end of the sliding mounting groove, and a snap-fit opening is provided on the chamfer. The end of the protective cover plate 7 is inclined to correspond to the chamfer, and... The bottom surface is provided with corresponding snap-fit protrusions; the cooperation between the rectangular groove and the rectangular insert ensures the smoothness and stability of the sliding of the protective cover 7. The cooperation between the snap-fit and the snap-fit protrusions allows the protective cover 7 to be firmly installed in the sliding installation groove, effectively protecting the direct-connection detection head 6. The engineering plastic material of the protective cover 7 ensures structural strength while helping to achieve smooth sliding and stable snap-fit. The extension rod 11 is provided with a V-shaped docking groove, and the inner wall of the sleeve 13 is provided with protrusions corresponding to the V-shaped docking groove. The connecting wire 4 is provided with an abutment block at the bottom end of the sleeve 13. The cooperation between the V-shaped docking groove and the protrusions ensures the stability of the extension rod 11 when it extends and retracts in the sleeve 13, preventing the extension rod 11 from shaking or shifting. The abutment block can limit and protect the connecting wire 4, avoiding damage to the connecting wire 4 during use.
[0022] Working principle: When using this utility model, first connect one end of the connecting wire 4 to the adapter connector 5 on the detector 3 to establish a signal transmission path. Then, let the connecting wire 4 pass through the support telescopic rod 2 and connect the other end to the sensor detection ball 1. Subsequently, screw the internal threaded connector 8 on the sensor detection ball 1 to the external threaded connector 9 at the top of the extension rod 11 in the support telescopic rod 2 to complete the assembly. When facing the noise detection needs of narrow spaces such as narrow passages in old urban communities and small ventilation shafts inside buildings, the operator can apply external force according to the actual space depth to make the rubber protrusion 12 at the bottom of the extension rod 11 detach from the current fixing hole on the outer wall of the sleeve 13, flexibly stretch or retract the extension rod 11, and release it after adjusting it to a suitable length. External force causes the rubber protrusion 12 to engage with the corresponding fixing hole to lock the length of the support telescopic rod 2. Then, with the help of the support telescopic rod 2, the sensor detection ball 1 is extended into the narrow space. The sensor detection ball 1 captures noise sound waves and converts them into electrical signals, which are transmitted to the detector 3 for analysis and processing via the connecting wire 4. In everyday convenient testing scenarios, if the support telescopic rod 2 is not needed, the operator can slide the protective cover 7 laterally along the rectangular insert in the sliding mounting groove to open it. The sensor detection ball 1 is then fixed by screwing its own internal threaded connector 8 onto the corresponding threaded connection on the direct connection detection head 6 located on the protective cover 7 on one side of the top surface of the detector 3. After the connection is completed, the operator can directly hold the detector 3 and use the sensor detection ball 1 to quickly obtain noise data in a normal environment.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
