[0024] The utility model provides a buzzer noise test mechanism, this buzzer noise test mechanism can be more accurate and simply adjust the distance between the buzzer with product and decibel appearance.

[0025] Figure 1 It is the axial side structure schematic diagram of the buzzer noise test mechanism provided by the utility model embodiment, Figure 2 It is Figure 1 It is the side view structure schematic diagram of the buzzer noise test mechanism, Figure 3 It is Figure 1 It is the top view structure schematic diagram of the buzzer noise test mechanism, Figure 4 It is Figure 1 It is the exploded structure schematic diagram of the buzzer noise test mechanism. As Figures 1 to 4 As shown in the figure, the buzzer noise test mechanism provided by the utility model embodiment includes substrate 10, first support column 20, second support column 30, first fixed clamp 40 and second fixed clamp 50. First support column 20 and second support column 30 are arranged on substrate 10, and slide rail 11 extending along a straight line is arranged on substrate 10, and at least one of first support column 20 and second support column 30 is slidably arranged in slide rail 11. First fixed clamp 40 is adjustably arranged on first support column 20, and second fixed clamp 50 is adjustably arranged on second support column 30.

[0026] In the embodiment, the decibel meter and the product with the buzzer can be arranged on the first fixing clamp 40 and the second fixing clamp 50 respectively; the height of the first fixing clamp 40 and the second fixing clamp 50 on the first supporting column 20 and the second supporting column 30 can be adjusted according to the requirement; finally, the distance between the first supporting column 20 and the second supporting column 30 can be adjusted according to the requirement, so as to complete the adjustment operation before the buzzer test. It can be understood that the adjustment can also be performed without following the above steps, as long as the distance between the decibel meter and the product with the buzzer and the height of each can be adjusted.

[0027] In the embodiment, since at least one of the first supporting column 20 and the second supporting column 30 is slidably arranged in the sliding rail 11, when the adjustment is performed, the adjustment of the distance between the first supporting column 20 and the second supporting column 30 can always be performed along the same straight line, so that the adjustment between the first supporting column 20 and the second supporting column 30 is facilitated. Therefore, the straight line distance between the first supporting column 20 and the second supporting column 30 can be adjusted more conveniently and accurately.

[0028] Further, in the embodiment, the first supporting column 20 is slidably arranged on the sliding rail 11; and the second supporting column 30 is fixed on the base plate 10.

[0029] Preferably, the sliding rail 11 can be a groove, the width of the bottom of the groove is greater than the width of the top, that is, the contraction portion 111 is formed at the top of the groove. The first supporting column 20 comprises a first base 21, a clamping block 22 and a first locking bolt 23. The first base 21 is arranged on the base plate 10, the clamping block 22 is arranged in the groove and connected with the base plate 10, and the first locking bolt 23 locks the first base 21 to fix the first base 21 on the base plate 10. The width of the bottom of the clamping block 22 is greater than the width of the top, so as to prevent the clamping block 22 from being taken out of the groove. In other words, when the clamping block 22 is combined with the first base 21, the contraction portion 111 at the top of the groove is clamped between the first base 21 and the clamping block 22. The clamping block 22 can slide in the sliding groove 11 to change the position of the first supporting column 20.

[0030] Further, the first through hole 211 is arranged on the first base 21, and the position of the first through hole 211 corresponds to the position of the groove when the first base 21 is arranged on the base plate 10. That is, the projection of the first through hole 211 to the direction of the groove falls in the groove. The top of the clamping block 22 is provided with the first connecting hole 221, and the first locking bolt 23 passes through the first through hole 211 and is connected with the first connecting hole 221 to complete the connection and fixation of the first base 21 and the clamping block 22.

[0031] When adjusting, the first locking bolt 23 can be loosened to increase the distance between the first locking bolt 23 and the first base 21, so that the first support column 20 can slide along the slide rail 11; after adjusting the distance between the first support column 20 and the second support column 30, the first locking bolt 23 can be tightened, so that the first base 21 and the clamping block 22 clamp the contraction part 111 of the slide rail 11.

[0032] The first support column 20 further comprises a first rod body 24, a second rod body 25 and a second locking bolt 26. The first rod body 24 is connected with the first base 21, and the second rod body 25 is movably arranged in the first rod body 24 from an end of the first rod body 24 away from the first base 21 along the axis of the second rod body 25. The first rod body 24 is provided with a second through hole 241, and the second locking bolt 26 passes through the second through hole 241 and abuts against the second rod body 25 to fix the first rod body 24 and the second rod body 25.

[0033] When adjusting the height of the first support column 20, the second locking bolt 26 can be loosened first, and then the depth of the first rod body 24 extending into the second rod body 25 is adjusted. After adjusting to the appropriate depth, the second locking bolt 26 is locked to complete the adjustment of the height of the first support column 20.

[0034] Further, in the embodiment, the second support column 30 comprises a second base 31 and a third locking bolt 32. The second base 31 is provided with a third through hole 311, and the third locking bolt 32 passes through the third through hole 311 and abuts against the base plate 10 to fix the second support column 30.

A fifth through hole 421 is arranged on the side of the second connecting tooth 42 (only one fifth through hole 421 on the side of one second connecting tooth 42 is shown due to the limitation of the view angle in the figure). A fifth locking bolt (not shown in the figure) passes through the fifth through hole 421 and abuts against the side of the first connecting tooth 41 to fix the first connecting tooth 41 and the second connecting tooth 42. The sound level meter can be supported on the plane formed by the first connecting tooth 41 and the second connecting tooth 42 and clamped between the first blocking edge 43 and the second blocking edge 44 to fix the sound level meter.

[0037] In order to facilitate the fixation of the sound level meter, the support plane for supporting the sound level meter formed by the first connecting tooth 41 and the second connecting tooth 42 is located on the horizontal plane, and the first blocking edge 43 and the second blocking edge 44 are arranged along the length direction of the slide rail 11 in sequence.

[0038] Similarly to the first fixing clamp 40, the second fixing clamp 50 is arranged on the end of the fourth rod 34 away from the third rod 33. The second fixing clamp 50 comprises a third connecting tooth 51, a fourth connecting tooth 52, a third blocking edge 53 and a fourth blocking edge 54.
