Description

Technical Field

[0001] The utility model relates to the technical field of acoustic measurement, in particular to a sound pressure sensor bracket. Background Art

[0002] The sound pressure sensor is used for acoustic measurement and is a device for detecting the sound pressure in the environment. When a sound wave reaches the sensor position, the sound pressure causes the internal diaphragm of the sensor to move, thereby changing the capacitance in the sensor. This capacitance change is converted into an electrical signal output, and after processing, the electrical signal is converted into a digital signal for subsequent analysis and processing. At present, when conducting acoustic experimental tests, sound pressure sensors are usually used to obtain sound pressure data in the environment. During measurement, the sensor is generally clamped and fixed at a certain position or height with a clip. However, the current clips are all threaded to ensure that the sensor position is fixed. After the threads are tightened, the correct orientation of the sound pressure sensor cannot be ensured. In addition, different experimental tests have different requirements for the height position of the sound pressure sensor. The current fixing method of the sound pressure sensor has poor adjustability and is difficult to meet different experimental test requirements. Utility Model Content

[0003] The utility model aims to provide a sound pressure sensor bracket to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0011] The beneficial effects of the utility model are:

[0012] When in use, the sound pressure sensor is clamped on the mounting clamp. The horizontal swing angle of the mounting clamp on the rotating seat is adjusted to achieve the adjustment of the inclination angle of the sound pressure sensor. The mounting clamp is then locked by the second locking mechanism. The rotation angle of the rotating seat on the support rod is adjusted to achieve the adjustment of the sound pressure sensor in all directions. The rotating seat is then locked by the first locking mechanism to achieve the direction adjustment of the sound pressure sensor during the actual measurement process. In addition, the position height of the sound pressure sensor is adjusted by adjusting the telescopic height of the support rod to meet different experimental test requirements.

[0016] As a further improvement of the above technical solution, the fixing column is threadedly connected to the supporting rod.

[0017] The fixing column and the support rod in this solution are connected by threads to achieve detachability. During assembly, the fixing column and the rotating seat can be pre-installed and then installed on the support rod.

[0018] As a further improvement of the above technical solution, the top of the rotating seat is provided with at least two first hinged plates arranged side by side at intervals, the lower end of the mounting clamp is provided with at least one second hinged plate arranged between the at least two first hinged plates, and the second locking mechanism includes a second locking bolt transversely connected between the second hinged plate and the first hinged plate.

[0022] As a further improvement of the above technical solution, it also includes a base, and the lower end of the support rod is detachably connected to the base.

[0023] The support rod in this solution can be installed on the base. In this installation method, the bracket can be moved at will. In other solutions, the support rod can be directly fixed to the trench cover to achieve fixed installation of the bracket.

[0024] As a further improvement of the above technical solution, the support rod includes a locking structure that is telescopically sleeved on at least two telescopic rods in sequence and is arranged between two adjacent telescopic rods.

[0025] When the telescopic height of the support rod needs to be adjusted, the locking structure is released, the relative positions between the telescopic rods are adjusted, and then the two adjacent telescopic rods are locked by the locking structure.

[0026] As a further improvement of the above technical solution, the locking structure includes a locking kit and a locking bolt, the locking kit includes a first locking sleeve that is sleeved on one of the telescopic rods, and a second locking sleeve that is sleeved on the other telescopic rod, the outer peripheries of the first locking sleeve and the second locking sleeve are both provided with shrinkage notches, and the two shrinkage notches are both connected to the locking bolts so that the first locking sleeve and the second locking sleeve can shrink and lock the telescopic rods.

When adjusting, one of the locking bolts is loosened so that one of the telescopic rods can move relative to the locking kit. It can be understood that at this time, the telescopic rod can be freely extended and retracted relative to the other telescopic rod to adjust the telescopic height of the support rod. After adjusting to the set length, the locking bolt is tightened to realize the locking of the two adjacent telescopic rods, and the assembly operation is convenient.

[0028] As a further improvement of the above technical solution, a connection portion located on the back side of the shrinkage notch is provided between the first locking sleeve and the second locking sleeve, and the shrinkage notch is connected to two connecting plates arranged opposite to each other, and the locking bolt is connected between the two connecting plates.

[0040] like Figure 1 and Figure 2 As shown, the sound pressure sensor bracket of this embodiment includes a support rod 100, a rotating seat 200, a first locking mechanism, a mounting clamp 300 and a second locking mechanism.

[0041] The support rod 100 is extended up and down, and the support rod 100 adopts a telescopic and adjustable rod structure.

[0042] The rotating seat 200 is rotatably installed at the upper end of the support rod 100, and the rotating seat 200 can rotate around the vertical axis relative to the support rod 100. The rotating seat 200 of this embodiment rotates relative to the axis of the support rod 100, and the first locking mechanism is arranged between the rotating seat 200 and the support rod 100, and the first locking mechanism is used to lock the rotation of the rotating seat 200.

[0043] The mounting clip 300 of this embodiment is rotatably mounted on the top of the rotating seat 200. The mounting clip 300 is provided with an elastic clamping groove 310. The mounting clip 300 clamps the sound pressure sensor 400 through the elastic clamping groove 310. The second locking mechanism is provided between the mounting clip 300 and the rotating seat 200. The second locking mechanism is used to lock the rotation of the mounting clip 300.

[0044] When in use, the sound pressure sensor 400 is clamped on the mounting clamp 300. The horizontal swing angle of the mounting clamp 300 on the rotating seat 200 is adjusted to achieve the adjustment of the inclination angle of the sound pressure sensor 400. The mounting clamp 300 is then locked by the second locking mechanism. The rotation angle of the rotating seat 200 on the support rod 100 is adjusted to achieve the adjustment of the sound pressure sensor 400 in all directions. The rotating seat 200 is then locked by the first locking mechanism to achieve the direction adjustment of the sound pressure sensor 400 during the actual measurement process. In addition, the position height of the sound pressure sensor 400 is adjusted by adjusting the telescopic height of the support rod 100 to meet different experimental test requirements. The operation is convenient and the adjustment is flexible.

[0045] The installation method of the rotating seat 200 is as follows: Figure 1 and Figure 2 As shown, a fixing column 500 is installed at the upper end of the support rod 100 of this embodiment, and the fixing column 500 is vertically arranged. A rotating hole is arranged at the bottom of the rotating seat 200, and the rotating hole is rotatably fitted with the fixing column 500 to realize the rotation of the rotating seat 200 relative to the support rod 100.

[0046] In this embodiment, a limiting groove 510 in an annular shape is provided on the outer peripheral wall of the fixed column 500, and a first screw hole 210 is provided on the outer peripheral wall of the rotating seat 200. The first screw hole 210 is threadedly connected to a limiting screw 211. The limiting screw 211 is connected to the first screw hole 210 from the outside to the inside. The inner end of the limiting screw 211 extends into the limiting groove 510 and engages with the limiting groove 510 to limit the relative movement of the fixed column 500 and the rotating seat 200 in the up and down directions.

[0047] This embodiment is achieved by the rotational fitting of the rotating hole and the fixed column 500, and the axial locking between the fixed column 500 and the rotating seat 200 is achieved by the engagement of the limit screw 211 and the limit groove 510 without affecting the relative rotation between the fixed column 500 and the rotating seat 200. During assembly, the fixed column 500 is inserted into the rotating hole, and then the limit screw 211 is screwed in, so that the limit screw 211 extends into the limit groove 510, which can improve the stability of the rotational connection between the support rod 100 and the rotating seat 200, and also improve the convenience of disassembly and assembly.

[0048] In other embodiments, other rotational connection methods may be used between the rotating seat 200 and the support rod 100 .

[0049] The first locking mechanism of this embodiment includes a first locking bolt 221. A second screw hole 220 is provided on the outer peripheral wall of the rotating base 200. The first locking bolt 221 is connected to the second screw hole 220 from the outside to the inside. The inner end of the first locking bolt 221 abuts against the outer peripheral wall of the fixing column 500.

[0050] In this embodiment, the first locking bolt 221 is abutted against the outer wall of the fixing column 500 to achieve locking of the rotating base 200. After the rotating base 200 is adjusted to a preset rotation direction, the first locking bolt 221 is tightened to lock the rotating base 200, which is easy to operate.

[0051] In other embodiments, the first locking mechanism may adopt other locking methods.

[0052] Furthermore, the fixed column 500 of the present embodiment is connected to the support rod 100 by means of threads to achieve detachability. During assembly, the fixed column 500 and the rotating seat 200 can be pre-assembled and installed, and then installed on the support rod 100. Specifically, a threaded column 110 is coaxially arranged at the top end of the support rod 100, and a fixing screw hole is arranged at the bottom end of the fixed column 500, and the fixing screw hole is threadedly connected to the threaded column 110.

[0053] Regarding the installation method of the mounting clamp 300, in this embodiment, at least two first hinged plates 230 are arranged on the top of the rotating seat 200, and the at least two first hinged plates 230 are arranged side by side at intervals, and the first hinged plate 230 is arranged vertically. At least one second hinged plate 320 is arranged at the lower end of the mounting clamp 300, and at least one second hinged plate 320 is arranged between at least two first hinged plates 230. The second hinged plate 320 and the first hinged plate 230 are both provided with hinge holes 321 that correspond to each other laterally, and the second locking mechanism includes a second locking bolt 600, and the second locking bolt 600 is laterally connected between the second hinged plate 320 and the first hinged plate 230.

[0054] In this embodiment, the second hinge piece 320 and the first hinge piece 230 are hinged together by the second locking bolt 600 to realize the rotational installation of the installation clip 300 and simultaneously realize the rotational locking of the installation clip 300 .

[0055] The support rod 100 includes at least two telescopic rods 120 and a locking structure 130. The at least two telescopic rods 120 are telescopically fitted in sequence, and the locking structure 130 is arranged between two adjacent telescopic rods 120. When the telescopic height of the support rod 100 needs to be adjusted, the locking structure 130 is released, the relative position between the telescopic rods 120 is adjusted, and then the two adjacent telescopic rods 120 are locked by the locking structure 130.

[0056] For the specific structure of the locking structure 130, such as Figure 3 As shown, the locking structure 130 of this embodiment includes a locking kit 131 and a locking bolt 132, wherein the locking kit 131 includes a first locking sleeve 1311 and a second locking sleeve 1312, the first locking sleeve 1311 and the second locking sleeve 1312 are connected to each other, the first locking sleeve 1311 is sleeved on one of the telescopic rods 120, and the second locking sleeve 1312 is sleeved on the other telescopic rod 120, and the outer peripheries of the first locking sleeve 1311 and the second locking sleeve 1312 are both provided with shrinkage notches 1313, and the two shrinkage notches 1313 are both connected with locking bolts 132, so that the first locking sleeve 1311 and the second locking sleeve 1312 shrink and lock the telescopic rod 120.

[0057] In this embodiment, the locking kit 131 is respectively mounted on two adjacent telescopic rods 120 through the first locking sleeve 1311 and the second locking sleeve 1312 to achieve the connection of the two adjacent telescopic rods 120, and each of the first locking sleeve 1311 and the second locking sleeve 1312 is provided with a locking bolt 132 to lock the contraction notch 1313 to achieve the contraction of the first locking sleeve 1311 and the second locking sleeve 1312. When adjusting, one of the locking bolts 132 is loosened so that one of the telescopic rods 120 can move relative to the locking kit 131. It can be understood that at this time, the telescopic rod 120 can be freely extended and retracted relative to the other telescopic rod 120 to adjust the telescopic height of the support rod 100. When adjusted to the set length, the locking bolt 132 is tightened to achieve the locking of the two adjacent telescopic rods 120, and the assembly operation is convenient.

[0058] A connecting portion 1314 disposed on the back side of the contraction notch 1313 is disposed between the first locking sleeve 1311 and the second locking sleeve 1312. Two connecting plates 1315 disposed opposite to each other are connected to the two sides of the contraction notch 1313. The locking bolt 132 is connected between the two connecting plates 1315. The locking bolt 132 tightens the contraction notch 1313 by tightening the two connecting plates 1315. It can be understood that the pressing force connected by the locking bolt 132 changes the aperture of the first locking sleeve 1311 and the second locking sleeve 1312, thereby fixing the two telescopic rods 120 and changing the length of the support rod 100. The connecting portion 1314 is disposed on the back side of the contraction notch 1313, which can make the contraction of the first locking sleeve 1311 and the second locking sleeve 1312 smoother.

[0059] When in use, the first locking sleeve 1311 is fixed, and the second locking sleeve 1312 is adjustable. Under normal circumstances, the first locking sleeve 1311 is tightly fixed on a telescopic rod 120. When the length of the support rod 100 needs to be adjusted, the locking bolt 132 on the second locking sleeve 1312 is loosened, the other telescopic rod 120 is pulled, and then the locking bolt 132 is tightened. Therefore, the locking bolt 132 on the second locking sleeve 1312 can be a hand-tightened bolt that is easy to operate.

[0060] The locking kit 131 of this embodiment is a plastic kit. Since plastic parts have good plasticity, the aperture of the plastic kit can be changed by the pressing force of the locking bolt 132, thereby fixing the two telescopic rods 120 and achieving the change of the length of the support rod 100.

[0061] The first locking bolt 221 and the second locking bolt 600 may also be hand-tightened bolts that are easy to operate.

[0062] The support rod 100 of this embodiment is a hollow structure, and a threading channel is provided inside the support rod 100 along the axial direction. Figure 4As shown, the wire threading channel is provided with a first wire opening 140 located at the upper part of the support rod 100 and a second wire opening 150 located at the lower part of the support rod 100. The cable of the sound pressure sensor 400 is hidden and installed in the wire threading channel, so that the overall bracket is more concise. During installation, the cable of the sound pressure sensor 400 is inserted from the first wire opening 140, passes through the wire threading channel, and then passes out from the second wire opening 150 to be connected with external equipment.

[0063] In some embodiments, a base 700 is further included, and the lower end of the support rod 100 is detachably connected to the base 700, and the support rod 100 can be installed on the base 700. Figure 1 and Figure 4 As described above, the base 700 of this embodiment is a disc structure, and the bracket can be moved at will.

[0064] In some embodiments, Figure 5 As shown, the base 700 is a trench cover, the lower end of the support rod 100 is threadedly connected to the trench cover, the trench cover is fixed on the trench, and the cables are hidden and installed in the trench. When the bracket does not need to be installed, the cover covers the screw holes on the trench cover.

[0065] A screw tube 160 is provided at the lower end of the support rod 100, and the screw tube 160 is connected to a round platform 170, and the round platform 170 is connected to the base 700 through a stud. The round platform 170 can improve the stability of the support to increase the stability of the bracket after installation.
