Abstract
The utility model provides a kind of impedance tube fixed mechanism, including base, support plate and at least two lantern rings, and the vertically arranged support plate is fixed with the base, at least two to be arranged in parallel up and down the lantern ring is provided with the support plate.Above-mentioned impedance tube fixed mechanism, due to that equipped with the multiple lantern rings being arranged in parallel up and down, the impedance tube cylinder of setting can be set in the lantern ring, the fixed impedance tube erect, beneficial to being smoothed out for vertical impedance tube method；Further, since equipped with vertical sliding slot, round turntable can be moved up and down, so as to drive the lantern ring to move up and down, position of the round turntable in sliding slot can be adjusted according to the drum length of impedance tube, it is simple and convenient, and adaptability is stronger.
Description
Technical field
Impedance tube field is the utility model is related to, more particularly to a kind of impedance tube fixed mechanism.
Background technology
More and more with sound insulation value requirement is inhaled to automotive interior material, the test of impedance tube method is also therewith using increasingly
Frequently.Existing impedance tube method is generally tested using horizontal type, but also begins to be tested using setting impedance tube method now, but existing
There is equipment without for the dedicated fixed mechanism of setting impedance tube method test.
Utility model content
Based on this, it is necessary to provide a kind of impedance tube fixed mechanism that can be used for erectting impedance tube method.
A kind of impedance tube fixed mechanism, including base, support plate and at least two lantern rings, are fixed with the base perpendicular
To the support plate of setting, at least two to be arranged in parallel up and down the lantern ring is installed in the support plate.
Above-mentioned technical proposal, can be by the impedance tube cylindrical sleeve of setting due to equipped with the multiple lantern rings being arranged in parallel up and down
It is located in the lantern ring, the fixed impedance tube erect, beneficial to being smoothed out for vertical impedance tube method.
In one of the embodiments, round turntable is further included, it is parallel successively on the round turntable to be equipped with least two
The lantern ring, the support plate are equipped with vertical sliding slot, and the round turntable center is equipped with first through hole, is worn with bolt
Coordinate after crossing first through hole and sliding slot with nut, the round turntable is slided up and down with the support plate and is connected.
Above-mentioned technical proposal, due to that equipped with vertical sliding slot, round turntable can be moved up and down, so as to drive on the lantern ring
Lower movement, can adjust position of the round turntable in sliding slot according to the drum length of impedance tube, simple and convenient, and adaptability is more
By force.
In one of the embodiments, the support plate is equipped with arc-shaped slot around the sliding slot, and the circle turns
Disk and arc-shaped slot correspondence position are equipped with the second through hole, with bolt pass through after the second through hole and the arc-shaped slot with nut
Coordinate, the round turntable and the support plate are rotatablely connected.
Above-mentioned technical proposal, due to that equipped with arc-shaped slot, round turntable can be made to be rotated in arc-shaped slot, according to
The direction and position of the adjustment lantern ring are needed, can be installed or removed when the lantern ring turns to horizontal level in impedance tube cylinder
Exemplar, it is simple to operate.
In one of the embodiments, the lantern ring is double semicircular ring clamping hoop type structures.
Above-mentioned impedance tube fixed mechanism, can be by the impedance of setting due to equipped with the multiple lantern rings being arranged in parallel up and down
Pipe cylinder is set in the lantern ring, the fixed impedance tube erect, beneficial to being smoothed out for vertical impedance tube method；Further, since it is equipped with
Vertical sliding slot, can move up and down round turntable, so as to drive the lantern ring to move up and down, can be grown according to the cylinder of impedance tube
Degree adjusts position of the round turntable in sliding slot, simple and convenient, and adaptability is stronger.
Brief description of the drawings
Fig. 1 is the left view of the impedance tube fixed mechanism of the utility model；
Fig. 2 is the front view of the support plate of the utility model；
Fig. 3 is universities and colleges' turntable of the utility model and the front view of the lantern ring.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1 ~ 3, a kind of impedance tube fixed mechanism, including base 1, support plate 2, at least two lantern rings 3 and fortune
Row turntable 4, is fixed with vertically arranged support plate 2 on base 1, parallel successively on round turntable 4 to be equipped with least two lantern rings 3,
The lantern ring 3 is double semicircular ring clamping hoop type structures.
Support plate 2 is equipped with vertical sliding slot 21, and arc-shaped slot 22,4 centre bit of round turntable are equipped with around sliding slot 21
First through hole 41 is installed, round turntable 4 is equipped with the second through hole 42 with 22 correspondence position of arc-shaped slot, and first is passed through with bolt
Coordinate after through hole 41 and sliding slot 21 with nut, round turntable 4 is slided up and down with support plate 2 and is connected；It is logical through second with bolt
Coordinate behind hole 42 and arc-shaped slot 22 with nut, round turntable 4 and support plate 2 are rotatablely connected.
Above-mentioned impedance tube is with the use process of fixed mechanism：The cylinder of impedance tube is clamped on the lantern ring 3, according to
The drum length requirement of impedance tube, by adjusting position of the first through hole 41 in sliding slot 21, is being propped up so as to adjust round turntable 4
Position on fagging 2, first passes through and adjusts position of second through hole 42 in arc-shaped slot 22, adjusts cylinder to horizontal level,
Exemplar is placed in cylinder, rear round turntable 4 to the cylinder that rotates is located at vertical position, carries out inhaling sound insulation value test, test
After, rotate round turntable 4 to the lantern ring 3 and be horizontally situated, dismantle exemplar.
Embodiment described above only expresses the several embodiments of the utility model, its description is more specific and detailed,
But it should not be interpreted as limiting the scope of the present invention.It should be pointed out that for the common of this area
