Description

Technical Field

[0001] This utility model relates to the field of fixing fixture technology, specifically to a sound calibrator fixture. Background Technology

[0002] Sound calibrators are mainly used to calibrate sound level meters or other acoustic measurement equipment to ensure the accuracy of measurement results. They calibrate sound level meters by emitting a standard sound signal with a known sound pressure level and frequency, ensuring the accuracy and reliability of the measurement process. Sound calibrators are commonly used in laboratories, factories, environmental monitoring stations, and other places where acoustic measurement equipment needs to be calibrated regularly. When using a sound calibrator, a fixing fixture is required to secure it.

[0003] To facilitate the installation and fixation of the sound calibrator, existing technologies have made numerous improvements to the sound calibrator fixture. For example, patent publication number CN219994846U discloses a sound calibrator fixture, relating to the field of sound calibrator technology. It includes a fixing block and a fixing plate. A protective box is fixed to one end of the fixing block, and a central shaft is fixed inside the protective box. A gear rotates on the central shaft. A first toothed plate and a second toothed plate slide inside the protective box. Limiting blocks are fixed to one side of both the first and second toothed plates, and these limiting blocks are slidably connected to the inner wall of the protective box. A connecting block is fixed to the other side of the first and second toothed plates, and a clamping block is fixed to one end of the connecting block. An instrument is mounted inside the clamping block. Both the first and second toothed plates mesh with the gear. This utility model increases the friction between the fixture and the protective box by having multiple structures move together. Then, through the thrust of a first spring, the clamping block engages with the fixing groove, preventing the entire structure from moving and making the fixture's clamping block more secure in fixing the sound calibrator.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned prior art describes how two toothed plates move relative to each other, causing two clamping blocks to hold and fix the acoustic calibrator. However, in reality, there are many types of acoustic calibrators, mainly cylindrical or rectangular in shape, and they vary in size. The aforementioned fixing fixture can only hold and fix acoustic calibrators of one shape, which reduces the applicability of the fixing fixture. Therefore, there is an urgent need in the art to improve the acoustic calibrator fixture to overcome the shortcomings of the prior art. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0033] Please see Figures 1-9 A sound calibrator fixture includes a support base 1, a rotating seat 2 rotatably connected to the upper part of the support base 1, a vertical support column 3 fixedly mounted on the upper part of the rotating seat 2, and a horizontal support column 5 penetrating the opposite sides of the vertical support column 3. A first fixed seat 6 and a second fixed seat 9 are respectively provided at both ends of the horizontal support column 5. Two symmetrical clamping frames 7 are provided on the side of the first fixed seat 6 away from the horizontal support column 5, and elastic plates 8 are provided on the opposite sides of each of the two clamping frames 7. Two symmetrical main clamping plates 10 are provided on the side of the second fixed seat 9 away from the horizontal support column 5. The vertical support column 3 is provided with a vertical adjustment unit for driving the vertical moving seat 4 to move up and down. The ends of the first fixed seat 6 and the second fixed seat 9 are each provided with a spacing adjustment unit for adjusting the distance between the two clamping frames 7 and the two main clamping plates 10. The spacing adjustment unit includes a first sliding block 1 fixedly mounted on one end of the clamping frame 7 or the main clamping plate 10. 1. The first fixed seat 6 and the second fixed seat 9 are both provided with a first sliding groove 12 adapted to the first sliding block 11 on their sides. The ends of the first fixed seat 6 and the second fixed seat 9 are both connected to a first adjusting threaded rod 13 extending into the first sliding groove 12. The first adjusting threaded rod 13 is threadedly connected to a first limiting nut 14 on its side. When the first adjusting threaded rod 13 rotates, it drives the two first sliding blocks 11 to move towards or away from each other at the same time. The up and down adjustment unit includes a third sliding block 22 fixedly installed on one side of the up and down moving seat 4. The vertical support column 3 is provided with a through groove 21 adapted to the up and down moving seat 4 on its opposite side. The inner side wall of the through groove 21 is provided with a third sliding groove 23 adapted to the third sliding block 22. The upper end of the vertical support column 3 is connected to a third adjusting threaded rod 24 through and rotatably. The third adjusting threaded rod 24 is threadedly connected to the third sliding block 22. The upper side of the third adjusting threaded rod 24 is threadedly connected to a third limiting nut 25.

[0034] The specific implementation method in this embodiment is as follows: When it is necessary to fix the sound calibrator, the fixing fixture is moved to the designated position. If the sound calibrator is round, the sound calibrator is placed between two elastic plates 8. By rotating the first adjusting thread rod 13, the threads of the first adjusting thread rod 13 on the side of the first sliding groove 12 are symmetrical and opposite. When the first adjusting thread rod 13 rotates, it drives the two first sliding blocks 11 to move towards each other in the first sliding groove 12. The first sliding blocks 11 drive the clamping frame 7 to move. The two clamping frames 7 move towards each other and the sound calibrator is clamped by the elastic plate 8. Then, the first limiting nut 14 is locked to limit and fix the position of the first adjusting thread rod 13. By setting the elastic plate 8, sound calibrators of different sizes can be clamped and fixed.

[0035] When clamping and fixing a rectangular acoustic calibrator, the acoustic calibrator is placed between two main clamping plates 10. By rotating the first adjusting threaded rod 13, the two main clamping plates 10 are moved in opposite directions to adjust the two main clamping plates 10 to clamp and fix the acoustic calibrator. This method can also clamp and fix rectangular acoustic calibrators of different sizes.

[0036] When the height of the acoustic calibrator needs to be adjusted, the third adjusting threaded rod 24 is rotated. When the third adjusting threaded rod 24 rotates, it drives the third sliding block 22 to move within the third sliding groove 23. The third sliding block 22 drives the upper and lower moving seat 4 to move up and down within the vertical support column 3. The upper and lower moving seat 4 drives the horizontal support column 5 to move up and down. After the height of the acoustic calibrator is adjusted, the third limiting nut 25 is locked to limit and fix the position of the third adjusting threaded rod 24. The rotating seat 2 is rotatably connected to the upper part of the bearing base 1. By rotating the vertical support column 3, the direction of the acoustic calibrator can be adjusted, thus achieving the effect of adjusting the vertical position of the acoustic calibrator. Example

[0037] Please see Figure 4 and Figure 9 This embodiment includes the above embodiment, and further includes: a fixed clamping plate 15 fixedly connected to the side of the main clamping plate 10 and a movable clamping plate 16 adapted to the fixed clamping plate 15 slidably connected; a second sliding block 17 fixedly installed on one side of the movable clamping plate 16; a second sliding groove 18 adapted to the second sliding block 17 opened on the side of the main clamping plate 10; a second adjusting threaded rod 19 extending into the second sliding groove 18 and rotatably connected to one end of the main clamping plate 10; the second adjusting threaded rod 19 being threadedly connected to the second sliding block 17; a second limiting nut 20 threadedly connected to the side of the second adjusting threaded rod 19; plug-in blocks 34 fixedly connected to both ends of the elastic plate 8; and plug-in grooves 35 adapted to the plug-in blocks 34 opened at both ends of the clamping frame 7.

[0038] The specific implementation method in this embodiment is as follows: The sound calibrator is placed between two main clamping plates 10, two fixed clamping plates 15, and two movable clamping plates 16. By rotating the first adjusting threaded rod 13, the two main clamping plates 10 are clamped on opposite sides of the sound calibrator. By rotating the second adjusting threaded rod 19, the second sliding block 17 is driven to move within the second sliding groove 18. The fixed clamping plates 15 and the movable clamping plates 16 clamp the other opposite sides of the sound calibrator. The second limiting nut 20 is locked to limit and fix the position of the second adjusting threaded rod 19, thereby improving the stability of the sound calibrator after clamping. If the elastic coefficient of the elastic plate 8 decreases or is not compatible with the sound calibrator, the plug-in blocks 34 at both ends of the elastic plate 8 are plugged into the plug-in slots 35 on the clamping frame 7, so that the elastic plate 8 can be installed or replaced later, thereby improving the applicability of the overall device. Example

[0039] Please see Figure 6 and Figure 8 This embodiment includes all the above embodiments, and further includes: a first positioning bolt 26 is threaded through and connected to the side of the upper and lower movable seat 4, one end of the first positioning bolt 26 abuts against the side of the transverse support column 5; a connecting rod 27 is fixedly installed on one side of the first fixed seat 6 and the second fixed seat 9; a circular rotating ball 28 is fixedly installed on one end of the connecting rod 27; a rotating groove 29 adapted to the rotating ball 28 is opened at both ends of the transverse support column 5; a second positioning bolt 30 is threaded through and connected to the side of both ends of the transverse support column 5, one end of the second positioning bolt 30 abuts against the side of the rotating ball 28.

[0040] In this embodiment, the horizontal support column 5 passes through the upper and lower movable seats 4, allowing adjustment of the horizontal position of the sound calibrator. After adjusting the horizontal position of the horizontal support column 5, the first positioning bolt 26, threadedly connected to the upper and lower movable seats 4, is tightened. One end of the first positioning bolt 26 abuts against the side of the horizontal support column 5, limiting and fixing the position of the horizontal support column 5. The rotating ball 28, larger than its radius, is located within the rotating groove 29. By rotating the first fixed seat 6 and the second fixed seat 9, the orientation of the installed sound calibrator can be adjusted. The rotating ball 28 rotates within the rotating groove 29. After adjusting the orientation of the sound calibrator, the second positioning bolt 30, threadedly connected to the side of the horizontal support column 5, is locked. One end of the second positioning bolt 30 abuts against the side of the rotating ball 28, fixing the position of the sound calibrator and improving the applicability of the overall device. Example

[0042] In this embodiment, the specific implementation method is as follows: When the vertical support column 3 is rotated, the rotating seat 2 rotates in the rotating groove 31. After the position of the sound calibrator is adjusted, the third positioning bolt 32 threaded on the rotating seat 2 is tightened. One end of the third positioning bolt 32 is tightly pressed against the bottom of the rotating groove 31 to fix the position of the rotating seat 2. The universal wheel 33 has a locking effect, which facilitates long-distance movement of the device.
