Description

Technical Field

[0001] This utility model relates to the field of sound level meter technology, specifically a sound level meter with a support structure. Background Technology

[0002] As a precision instrument used to measure the intensity of environmental noise, the sound level meter is widely used in environmental protection, industrial safety, architectural acoustics, and product quality testing.

[0003] In practical use, to ensure the accuracy and repeatability of measurement data, sound level meters usually need to maintain a stable posture at a specific height and direction. Especially in long-term fixed-point monitoring or complex sound field environments, handheld operation is prone to problems such as human shaking and angle deviation, which seriously affect the reliability of measurement results.

[0004] Traditional sound level meters are mostly handheld, which is convenient to carry but difficult to stabilize. Although some devices are equipped with simple tripods or support rods, they generally suffer from drawbacks such as inconvenient adjustment, weak locking, and limited freedom of movement. For example, existing support structures often only support angle adjustment in one direction, which cannot flexibly adapt to different sound source locations; some structures have pitch or rotation functions, but lack effective multi-position positioning and rigid locking mechanisms, making them prone to displacement under wind, vibration, or slight touch, leading to measurement errors.

[0005] Therefore, we propose a sound level meter with a support structure to address the problems mentioned above. Utility Model Content

[0006] 1. The technical problem to be solved by the utility model: The purpose of this invention is to provide a sound level meter with a support structure to solve the problems currently found in the market as described in the background.

[0007] 2. Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: a sound level meter with a support structure, comprising a base component and a sound level meter body, wherein a vertical rod is movably mounted on the upper end of the base component via a connector, and the connector is used to limit the angle of the vertical rod on the base component; A fixed base is fixedly installed at the upper end of the vertical rod, and an mounting component is rotatably assembled on the fixed base. The sound level meter body is detachably installed on the fixed base through the mounting component. The mounting base is also equipped with a positioning component, which is used to lock the angle of the mounting component on the mounting base.

[0008] Furthermore, at least three suction cups are uniformly installed at the lower end of the base component, and the suction end faces of each suction cup are arranged in a coplanar manner.

[0009] The above technical solution allows the device to adhere to the table surface via suction cups, thus improving placement stability.

[0010] Furthermore, the connector includes a first positioning plate, a connecting post, and a second positioning plate; The first positioning plate is fixed above the middle part of the base component; The lower end of the connecting column is fixedly connected to the upper part of the middle of the first positioning disk, and a cylindrical magnetic block is fixedly installed on the upper end of the connecting column. The lower end of the vertical rod has a vertically extending receiving cavity. The magnetic block is vertically fitted and slidably installed on the inner wall of the receiving cavity. An iron sheet is fixedly connected to the area of ​​the magnetic block on the top inner wall of the receiving cavity. The magnetic block and the iron sheet are magnetically attracted to each other. The second positioning disc is sleeved and fixed on the outer side of the lower end of the vertical rod; The upper surface of the first positioning disk has several positioning grooves at equal angles. The lower surface of the second positioning disk is fixed with a positioning protrusion that is adapted to the positioning grooves. The second positioning disk achieves rotational positioning with the first positioning disk through the cooperation of the positioning protrusion and the positioning groove.

[0011] The above technical solution enables the positioning protrusion to disengage from the positioning groove when the vertical rod is lifted, allowing it to rotate laterally and then move downwards to achieve positioning through the interlocking of the protrusion and concave parts. The magnetic attraction between the iron sheet and the magnetic block is used to improve the stability after positioning.

[0012] Furthermore, a mounting slot is fixedly connected to the rear side of the sound level meter body; The mounting component includes a rotating rod and a mounting block. The rotating rod is rotatably mounted on the fixed base via a damping bearing. The mounting block is fixedly sleeved on the outer side of the middle part of the rotating rod, and a number of rubber protrusions are provided on the side of the mounting block. The mounting block engages with the inner wall of the mounting groove via rubber protrusions.

[0013] The above technical solution allows for quick assembly and disassembly by engaging the rubber protrusions with the mounting block.

[0014] Furthermore, the positioning assembly includes a bidirectional threaded rod, two sets of movable parts, two knobs, and two fourth positioning discs; The bidirectional threaded rod is rotatably mounted inside the fixed base via a bearing; The two sets of movable parts are respectively sleeved on the outer sides of both ends of the bidirectional threaded rod; The two knobs are respectively fixed at both ends of the bidirectional threaded rod; Two fourth positioning discs are fixed at both ends of the rotating rod, and the fourth positioning discs are correspondingly arranged with the movable part.

[0015] The above technical solution enables the rotation of the bidirectional threaded rod via a knob, thereby driving the two moving parts to move relative to each other.

[0016] Furthermore, the movable component includes a movable plate, a rectangular block, and a third positioning disk, wherein the rectangular block and the third positioning disk are both fixed to the movable plate; The rectangular block and the bidirectional threaded rod form a threaded connection, and the rectangular block slides and fits into the guide groove inside the fixed seat; The fourth positioning disk has several positioning grooves two at equal angles on the side close to the corresponding third positioning disk, and the third positioning disk has a positioning protrusion two that is adapted to the positioning groove two on the side close to the corresponding fourth positioning disk. The third positioning disk achieves rotational locking of the fourth positioning disk through the interlocking of the positioning protrusion two with the positioning groove two.

[0017] The above technical solution enables the rotating rod to be locked when the positioning protrusion 2 and the positioning groove 2 are engaged.

[0018] 3. Beneficial effects: Compared with the prior art, the sound level meter with a supporting structure provided by this utility model improves measurement accuracy, ease of operation, and field adaptability through multi-level adjustment, dual locking, and suction cup stabilization structure. It is suitable for industrial, environmental protection, and scientific research scenarios that require long-term, high-precision fixed-point noise monitoring. The specific details are as follows: (1) The rubber protrusion on the mounting block engages with the mounting slot on the rear side of the sound level meter body to achieve quick positioning. The sound level meter body is then detachably mounted on the fixed seat, which is fixed to the top of the vertical rod. The vertical rod is movably mounted on the base component through the connector to achieve lateral angle adjustment. At the same time, the mounting component can rotate vertically on the fixed seat to achieve multi-degree-of-freedom attitude adjustment of the sound level meter body in space. (2) When the horizontal angle needs to be adjusted, lift the vertical rod upward, then rotate the vertical rod until it is rotated to the desired position, and then place the vertical rod downward. At this time, the positioning protrusion at the lower end of the second positioning plate can be embedded in the positioning groove on the first positioning plate to achieve multi-position angle limit. At the same time, the receiving cavity at the lower end of the vertical rod is provided with an iron sheet that magnetically attracts the magnetic block at the top of the connecting column to improve the connection stability in the locked state. (3) The positioning component drives the two movable parts on both sides to move closer or further away from the fourth positioning plate through the bidirectional threaded rod. When the knob is rotated, the bidirectional thread causes the two sets of movable parts to move towards each other. When the positioning protrusion of the third positioning plate on the movable part is embedded in the positioning groove of the fourth positioning plate, the rigid locking of the rotating rod angle is achieved, which improves the stability of the sound level meter body after rotation and extends the service life.

[0025] Please see Figure 1-5 A sound level meter with a support structure includes a base component 1 and a sound level meter body 4. A vertical rod 2 is movably mounted on the upper end of the base component 1 via a connector 3, which limits the angle of the vertical rod 2 on the base component 1. At least three suction cups 11 are evenly mounted on the lower end of the base component 1, and the suction end faces of each suction cup 11 are coplanar. The connector 3 includes a first positioning plate 31, a connecting post 32, and a second positioning plate 33. The first positioning plate 31 is fixed above the middle part of the base component 1. The lower end of the connecting post 32 is fixed above the middle part of the first positioning plate 31, and the upper end of the connecting post 32 is fixedly mounted on the base component 1. The vertical rod 2 is equipped with a cylindrical magnetic block 34. A vertically extending receiving cavity is opened at the lower end of the vertical rod 2. The magnetic block 34 is vertically fitted and slidably installed on the inner wall of the receiving cavity. An iron sheet is fixedly connected to the area of ​​the top inner wall of the receiving cavity corresponding to the magnetic block 34. The magnetic block 34 and the iron sheet are magnetically attracted to each other. The second positioning disk 33 is sleeved and fixed on the outer side of the lower end of the vertical rod 2. The upper end surface of the first positioning disk 31 is provided with several positioning grooves at equal angles. The lower end surface of the second positioning disk 33 is fixedly connected with a positioning protrusion that is compatible with the positioning grooves. The second positioning disk 33 achieves rotational positioning with the first positioning disk 31 through the cooperation of the positioning protrusion and the positioning groove. First, the base component 1 is fixed to the table surface by suction cup 11. The table base can be lifted. When the horizontal angle needs to be adjusted, lift the vertical rod 2 upward to make the positioning protrusion at the lower end of the second positioning plate 33 disengage from the positioning groove on the first positioning plate 31. Then rotate the vertical rod 2 until it is rotated to the desired position. Then lower the vertical rod 2. At this time, the positioning protrusion is embedded in the positioning groove to realize multi-position angle limit. At the same time, the receiving cavity at the lower end of the vertical rod 2 is provided with an iron plate that magnetically engages with the magnetic block 34 at the top of the connecting column 32 to improve the connection stability in the locked state. A fixed base 5 is fixedly installed at the upper end of the vertical rod 2. A mounting component 6 is rotatably assembled on the fixed base 5. The sound level meter body 4 is detachably installed on the fixed base 5 through the mounting component 6. A positioning component 7 is also installed on the fixed base 5. The positioning component 7 is used to lock the angle of the mounting component 6 on the fixed base 5. A mounting slot 41 is fixedly connected to the rear side of the sound level meter body 4. The mounting component 6 includes a rotating rod 61 and a mounting block 62. The rotating rod 61 is rotatably installed on the fixed base 5 through a damping bearing. The mounting block 62 is fixedly sleeved on the outer side of the middle part of the rotating rod 61. Several rubber protrusions 63 are provided on the side of the mounting block 62. The mounting block 62 is engaged with the inner wall of the mounting slot 41 through the rubber protrusions 63. The rubber protrusion 63 on the mounting block 62 engages with the mounting groove 41 on the rear side of the sound level meter body 4, enabling quick positioning. Thus, the sound level meter body 4 can be detachably mounted on the fixed base 5, allowing the sound level meter body 4 to be used independently or in conjunction with a support frame. The positioning assembly 7 includes a bidirectional threaded rod 71, two sets of movable parts 72, two knobs 73, and two fourth positioning discs 74. The bidirectional threaded rod 71 is rotatably mounted inside the fixed base 5 via bearings. The two sets of movable parts 72 are respectively sleeved on the outer sides of both ends of the bidirectional threaded rod 71. The two knobs 73 are respectively fixed to both ends of the bidirectional threaded rod 71. The two fourth positioning discs 74 are respectively fixed to both ends of the rotating rod 61, and the fourth positioning discs 74 are correspondingly arranged with the movable parts 72. The movable part 72 includes a movable plate 721, a rectangular block 722, and a third positioning disc 723. Both 22 and the third positioning plate 723 are fixed on the movable plate 721; the rectangular block 722 and the bidirectional threaded rod 71 form a threaded connection, and the rectangular block 722 slides and fits into the guide groove inside the fixed seat 5; the fourth positioning plate 74 has several positioning grooves two at equal angles on the side close to the corresponding third positioning plate 723, and the third positioning plate 723 has a positioning protrusion two that matches the concave and convex of the positioning groove two fixed on the side close to the corresponding fourth positioning plate 74. The third positioning plate 723 achieves rotation locking of the fourth positioning plate 74 through the concave and convex cooperation between the positioning protrusion two and the positioning groove two. When vertical adjustment is required, simply rotate the mounting part 6 on the fixed base 5. Then, rotate the knob 73 to drive the bidirectional threaded rod 71 to rotate. The bidirectional threaded rod 71 can drive the two movable parts 72 on both sides to move towards the fourth positioning plate 74 simultaneously. When the positioning protrusion 2 of the third positioning plate 723 on the movable part 72 is embedded in the positioning groove 2 of the fourth positioning plate 74, the angle of the rotating rod 61 is rigidly locked, which improves the stability of the sound level meter body 4 after rotation and extends its service life.

[0026] Working principle: When using a sound level meter with a supporting structure, such as... Figure 1-5As shown, the base component 1 is first fixed to the table surface by suction cup 11. The table base can be lifted. When horizontal angle adjustment is required, the vertical rod 2 is movably installed on the base component 1 through the connector 3 to achieve horizontal angle adjustment. At the same time, the mounting part 6 can rotate vertically on the fixed seat 5, thereby realizing the multi-degree-of-freedom attitude adjustment of the sound level meter body 4 in space. Then, the magnetic block 34 and the positioning component 7 are used to improve the stability after positioning. At the same time, the sound level meter body 4 forms a snap-fit ​​with the rubber protrusion 63 on the mounting block 62 through the mounting slot 41 to achieve quick positioning. Thus, the sound level meter body 4 can be disassembled and used alone, or it can be used with the support frame.
