[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] Please see Figure 1-10This utility model provides a noise detection device, including a detection body 1. A display screen 11 is fixedly connected to the front of the detection body 1. Multiple sets of buttons 12 are fixedly connected to the front of the detection body 1 and below the display screen 11. Multiple sets of wire holes 13 are opened on the lower surface of the detection body 1. A detection probe 2 is fixedly connected to the upper end of the detection body 1. A windproof cover 21 is fitted on the outer side of the detection probe 2. A bottom cover 3 for protecting the wire holes 13 is hinged to the bottom surface of the detection body 1. Guide rail seats 4 are symmetrically fixed on the left and right sides of the detection body 1. A T-shaped slide groove 41 is opened through the upper surface of the guide rail seat 4. The side of the T-shaped slide groove 41 away from the detection body 1 passes through the guide rail seat 4. A slider 5 is slidably connected inside the T-shaped slide groove 41. Block 5 is fixed to guide rail seat 4 by limiting member 6. The side of slider 5 away from the detection body 1 is fixedly connected to support cylinder 7 with open ends on both sides by connecting seat 54. Guide groove 71 is opened through the front and rear sides of support cylinder 7. Side seat 72 is fixedly connected to the end of support cylinder 7 away from connecting seat 54. Movable cylinder 8 is slidably connected inside support cylinder 7. Spring 83 is fixedly connected between movable cylinder 8 and side seat 72. Guide block 81 is symmetrically fixed on the front and rear sides of movable cylinder 8. Guide block 81 is slidably connected to the inner side of guide groove 71. Movable ring 82 is slidably sleeved on the outer side of support cylinder 7. The inner side of movable ring 82 is fixed to two sets of guide blocks 81. Auxiliary telescopic handle 9 is connected to the lower end of movable ring 82.

[0030] This invention features an auxiliary telescopic handle 9 on one side of the testing machine body 1. The distance between the auxiliary telescopic handle 9 and the testing machine body 1 can be flexibly adjusted by the elastic force of spring 83, thus meeting the operational needs of different operators. Specifically, during one-handed operation, the operator passes their hand through the gap between the testing machine body 1 and the auxiliary telescopic handle 9 to grip the testing machine body 1. At this time, under the elastic force of spring 83, the auxiliary telescopic handle 9 uses a flexible clamping method to firmly hold the operator's hand on one side of the testing machine body 1, enhancing stability during operation and greatly preventing accidental slippage. Simultaneously, the flexible clamping of spring 83 ensures effective gripping while preventing hand injury.

[0031] Furthermore, by adjusting the position and overall length of the auxiliary telescopic handle 9, noise detection at higher positions can be achieved. During the detection process, simply moving the auxiliary telescopic handle 9 downwards or changing its overall length allows the detection unit 1 to be easily raised to the desired height by holding the handle 9, making detection more convenient and improving efficiency. Specifically, when detecting noise at higher positions, the relative position of the slider 5 within the guide rail 4 can be adjusted to move the auxiliary telescopic handle 9 downwards. The operator can then hold the handle 9 to raise the detection unit 1. If further increases in height are needed, the overall length of the auxiliary telescopic handle 9 can be adjusted to further raise the detection unit 1.

[0032] Specifically, guide rail seats 4 are symmetrically fixed on the left and right sides of the testing machine body 1. The arrangement of the two sets of guide rail seats 4 allows the operator to flexibly select and install the position of the auxiliary telescopic handle 9 according to their own usage habits and needs, so that it can be used whether the operator is left-handed or right-handed.

[0033] Specific working steps: When conducting noise detection, the operator starts the detection unit 1 by pressing button 12. At this time, the detection unit 1 and the detection probe 2 begin operation, ready to collect and analyze data. When detecting at a low position, the operator can place their hand directly into the gap between the detection unit 1 and the auxiliary telescopic handle 9, using the elasticity of spring 83 to ensure stability when holding the detection unit 1. When detecting at a high position, the overall length of the auxiliary telescopic handle 9 can be adjusted first, and then the height of the detection unit 1 can be increased by holding the auxiliary telescopic handle 9. After adjustment, the operator begins the actual noise detection. During the detection process, the detection probe 2 collects environmental noise data in real time and displays this data on the display screen 11. After the detection is completed, the operator can view the detection results on the display screen 11.

[0034] It should be noted that the detection body 1, display screen 11, buttons 12, wire hole 13, detection probe 2, and wind shield 21 mentioned in this article are all existing technologies in the field. Operators can precisely operate the detection body 1 via buttons 12 to control its working status, start or stop the detection process, and adjust relevant parameters. During the detection process, the detection probe 2 collects ambient noise data in real time and transmits it to the detection body 1 for processing and display. The wind shield 21 effectively reduces interference from external environmental factors, such as wind and airflow, on the measurement accuracy of the detection probe 2, ensuring the accuracy of the detection results. The display screen 11 provides an intuitive interface, displaying real-time detection data and graphical results, enabling operators to quickly understand the current measurement situation and make corresponding adjustments. Furthermore, the wire hole 13 is used to connect related accessories or interfaces, facilitating equipment expansion and connection.

[0035] Furthermore, a magnet 31 is fixedly connected to the front side of the inner surface of the bottom cover 3, and a magnet 32 ​​that magnetically attracts the magnet 31 is fixedly connected to the front side of the lower surface of the detection body 1.

[0036] Specifically, the bottom cover 3 not only provides effective protection for the wire hole 13, but also ensures that the testing body 1 is protected from dust or foreign objects during long-term idle periods. When the testing body 1 is not in use, the operator only needs to gently press the bottom cover 3 onto the lower surface of the testing body 1. The magnetic attraction between the first magnet 31 and the second magnet 32 ​​will firmly connect the bottom cover 3 to the testing body 1, thereby preventing the entry of external dust. If cable connection is required, the user can pry the bottom cover 3 downwards to open the wire hole 13 for easy connection and use.

[0037] Furthermore, multiple sets of limiting grooves 42 are equidistantly provided on the front side of the T-shaped slide 41. The slider 5 has a movable groove 51 inside, and the movable groove 51 passes through the rear side of the slider 5. Two sets of longitudinally distributed through holes 52 are provided on the front side of the slider 5. Both sets of through holes 52 are connected to the movable groove 51. The limiting member 6 includes a movable plate 61 and two sets of limiting posts 62 fixedly connected to the front side of the movable plate 61. The movable plate 61 is slidably connected inside the movable groove 51. The two sets of limiting posts 62 are slidably connected inside the two sets of through holes 52 respectively. The head of the limiting post 62 is set as a hemispherical shape. The rear side of the slider 5 is fixedly connected to a rear cover 53 for sealing the movable groove 51 by screws. A spring 63 is fixedly connected between the movable plate 61 and the rear cover 53. The two sets of limiting posts 62 elastically abut against the corresponding limiting grooves 42 under the elastic force of the spring 63.

[0038] Specifically, the slider 5 and the guide rail seat 4 are slidably connected and relatively fixed by the limiting member 6. Under the elastic force of the spring 63, the movable plate 61 elastically abuts against the front side of the movable groove 51. At this time, the two sets of limiting posts 62 are elastically abutted against the inner side of the corresponding limiting grooves 42, thereby achieving elastic fixation of the relative position between the slider 5 and the guide rail seat 4. When it is necessary to adjust the relative position of the slider 5 in the T-shaped slide groove 41, simply apply a certain external force to push the slider 5 up or down. Under the action of the external force, since the head of the limiting post 62 is set as a hemispherical shape, the limiting post 62 will slide towards the movable groove 51 and squeeze the spring 63 through the movable plate 61, thereby realizing the adjustment of the slider 5 position. In addition, the movable groove 51 is closed by the back cover 53. When the parts in the movable groove 51 are damaged or need maintenance, the back cover 53 can be easily removed for maintenance and replacement.

[0039] Furthermore, a threaded hole 531 is provided through the center of the rear cover 53. The threaded hole 531 is internally threaded with a fixing bolt 64 for limiting the sliding of the movable plate 61. A through groove 43 is provided through the rear side of the T-shaped slide groove 41 to provide sliding space for the fixing bolt 64. The upper end of the through groove 43 passes through the guide rail seat 4.

[0040] Specifically, after the slider 5 is fixed in position, the operator tightens the fixing bolt 64. At this time, the movable plate 61 is firmly restricted to the front side of the movable groove 51 and cannot slide backward, thereby indirectly fixing the two sets of limiting posts 62 firmly in the corresponding limiting grooves 42, thus achieving the fixation of the relative position between the slider 5 and the guide rail seat 4. When it is necessary to adjust the relative position between the slider 5 and the guide rail seat 4, simply unscrew the fixing bolt 64 to allow the movable plate 61 to return to the sliding state.

[0041] Furthermore, a threaded hole 721 is provided through the center of the side seat 72, and a locking bolt 84 for restricting the movement of the movable cylinder 8 is connected to the internal thread of the threaded hole 721.

[0042] Specifically, when it is necessary to raise the detection height of the detection body 1 by means of the auxiliary telescopic handle 9, the relative position of the auxiliary telescopic handle 9 and the support cylinder 7 must first be fixed to ensure that the detection body 1 can maintain a relatively stable state when the auxiliary telescopic handle 9 is held. Specifically, tighten the locking bolt 84 inward, at which time the movable cylinder 8 is firmly fixed on the side of the support cylinder 7 away from the side seat 72, thereby fixing the relative position of the movable cylinder 8 and the support cylinder 7, and thus fixing the relative position of the auxiliary telescopic handle 9 and the support cylinder 7.

[0043] Furthermore, the auxiliary telescopic handle 9 includes an inner rod 91, a secondary sleeve 92 with an open upper end, and an outer sleeve 93 with an open upper end. A top block 911 is fixedly connected to the upper end of the inner rod 91, and the top block 911 is fixedly connected to the lower end of the movable ring 82. The secondary sleeve 92 is threaded onto the outer side of the inner rod 91, and the outer sleeve 93 is threaded onto the outer side of the secondary sleeve 92.

[0044] Specifically, the overall length of the auxiliary telescopic handle 9 can be adjusted according to the required detection height for flexible operation. During adjustment, the threaded engagement between the outer sleeve 93 and the secondary sleeve 92 allows the outer sleeve 93 to move downward relative to the secondary sleeve 92 when it rotates, thereby adjusting the overall length. The secondary sleeve 92 is also threadedly engaged with the inner rod 91, meaning that when the secondary sleeve 92 rotates, its position relative to the inner rod 91 also changes accordingly, thus adjusting the overall length of the auxiliary telescopic handle 9.

[0045] Furthermore, a soft handle cover 931 is detachably fitted on the outer side of the outer sleeve 93.

[0046] Specifically, the soft grip 931 increases the comfort of the operator when holding the auxiliary telescopic handle 9. Secondly, when the operator holds the testing body 1, the hand is clamped between the testing body 1 and the auxiliary telescopic handle 9. The soft grip 931 can relieve the clamping pressure between the hand and the hard part, thereby reducing discomfort during operation.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
