Background technology
The metering of acoustic transducer directive property is an important content of acoustic transducer pond metering, and is counted in equipment pond
The time longest expended in amount.The metering of acoustic transducer directive property is divided into horizontal directivity metering and vertical directivity measures two
Point.
Traditional directive property metering clamp uses stationary frame, in vertical directivity metering and horizontal directivity meter
Conversion between amount is typically that palpus remover-and-replacer is reinstalled, this directly results in repeated disassembled and assembled of gauge fixture and then wastes
The a large amount of time, and easily cause in disassembly process repeatedly the loss of micro parts.
Also, material is all metallicity used by traditional directive property gauge fixture, based on vertical directivity
When amount, connecting rod is connected by bolt with every baffle supporting rod again by the rectangular link block of its underpart, rectangular link block.Due to
Energy converter is heavier, and insufficient every the hardness of baffle supporting rod, supporting rod, which is easily deformed, causes energy converter to cannot keep upright position, leads
It causes directivity measurement to be susceptible to deviation, and then measurement accuracy is caused to reduce.
Therefore, it is highly desirable to improve existing fixture, designs a set of horizontal directivity and general two conjunctions of vertical directivity
One fixture improves measurement efficiency and measuring accuracy.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of general acoustics
Transducer directivity gauge fixture device, easy to operate, connection is firm, and various sizes of energy converter connection can be suitble to use.
The utility model uses technical solution below：
A kind of general acoustic transducer directive property gauge fixture device, including connecting flange, linking arm and reinforcing member, it is described
Linking arm be made of upper linking arm and lower linking arm, upper linking arm is connect with lower linking arm by bolt activity, described
Connecting flange is in disk form, is set on connecting flange there are four symmetrical threaded hole, and the side centre position of connecting flange, which is equipped with, to be connected
Crossbeam is connect, the both ends of connecting cross beam are equipped with through-hole, and described upper linking arm one end is movably connected in connecting cross beam two by through-hole
On the through-hole at end, the end of the lower linking arm is equipped with L-shaped foot pad, and L-shaped foot pad is equipped with foot pad through-hole, and foot pad through-hole passes through
Bolt is connected with acoustic transducer, and the right and left of the reinforcing member is arranged with slot, the upper linking arm side
Equipped with connection bolt, reinforcing member is flexibly connected by slot with bolt is connect, and connection bolt can move in slot.
The grip device is made of nonmetallic materials.
The material of the grip device is fiberglass.
The utility model has the beneficial effects that：
The utility model can be measured in vertical directivity and be converted between horizontal directivity metering, be become by being flexibly connected
The mode of shape realizes conversion, need not dismantle and reinstall, simple in structure, small, easy to carry, easy to operate, versatility
It is good, can be suitably used for various sizes of acoustic transducer, and be connected and fixed it is firm.
Description of the drawings
Using attached drawing, the utility model is described in further detail, but the embodiment in attached drawing is not constituted to the utility model
Any restrictions for those of ordinary skill in the art without creative efforts, can also be according to following attached
Figure obtains other attached drawings.
Fig. 1：The positive structure schematic of the utility model；
Fig. 2：The connecting flange vertical view of the utility model；
Fig. 3：The linking arm side cutting structural schematic diagram of the utility model；
Fig. 4：The utility model reinforcing member structural schematic diagram.
In figure：1 connecting flange, linking arm, 3 times linking arms, 4 connecting cross beams, 5 threaded holes, 6 through-holes, 7 bolts, 8 connect on 2
Connecting bolt, 9L shapes foot pad, 10 reinforcing members, 11 slots.
Specific implementation mode
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings and have
Body embodiment is described in further detail the utility model, it should be noted that in the absence of conflict, the application's
Feature in embodiment and embodiment can be combined with each other.
As shown in Figures 1 to 4, a kind of general acoustic transducer directive property gauge fixture device, including connecting flange 1, connection
Arm and reinforcing member 10, wherein the linking arm is made of upper linking arm 2 and lower linking arm 3, upper linking arm 2 and lower linking arm 3
It being connected by 7 activity of bolt, the connecting flange 1 is in disk form, is set on connecting flange 1 there are four symmetrical threaded hole 5,
The side centre position of connecting flange 1 is equipped with connecting cross beam 4, and the both ends of connecting cross beam 4 are equipped with through-hole 6, the upper linking arm 2
One end is movably connected in by through-hole on the through-hole 6 at 4 both ends of connecting cross beam, and the end of the lower linking arm 3 is equipped with L-shaped foot pad
