Description
Technical field
The present invention relates to a kind of adjustable for height shock absorber and anechoic room.
Background technology
Anechoic room is not only a special experimental laboratory of acoustical testing, and is the important component of test system, real
It is also one of acoustic test equipment on border, and its acoustical behavior index directly affects the precision of test.During acoustical testing,
To avoid the influence that external vibration is tested anechoic room internal acoustic, anechoic room can be built in the basis of a vibration reduction platform
On, by shock absorber, isolate the influence of external vibration.At present, more conventional way is to lay shock absorber on the ground, Ran Hou
A platform (such as pouring into a mould a layer concrete ground) is built on shock absorber, anechoic room is entirely built on this platform.Due to
Shock absorber can not adjust height, and anechoic room volume ratio is larger, and distribution of weight is uneven, causes each shock absorber unbalance stress
Even so that anechoic room can not keep level, shock absorber service life is short, effectiveness in vibration suppression weakens.
The content of the invention
It is an object of the invention to for drawbacks described above of the prior art is there is provided a kind of adjustable for height shock absorber and disappears
Sound chamber, shock absorber height can be adjusted, and the height or level of anechoic room can be adjusted by adjusting the height of shock absorber so that
Shock absorber uniform force.
For achieving the above object, present invention employs following technical scheme：A kind of adjustable for height shock absorber, including
Cushion blocking, the adjusting rod being rotatably connected with the cushion blocking and and the containment vessel that is connected of the adjusting rod, the containment vessel
It can be moved up and down relative to the adjusting rod.
In addition, the present invention also proposes following attached technical scheme：
The containment vessel can accommodate the cushion blocking when regulation is to extreme lower position.
The containment vessel section is stepped in what is changed from small to big.
The containment vessel is provided with the auxiliary section being threadedly coupled with the adjusting rod.
The regulation boom end, which offers to offer on interior hexagonal blind hole, the containment vessel, exposes the interior hexagonal blind hole
Opening.
A kind of to include the anechoic room of the as above any one adjustable for height shock absorber, it also includes being arranged at the noise elimination
The concrete platform of room bottom, the adjustable for height shock absorber is arranged in the concrete platform.
The concrete platform is offered and the through hole for being open and communicating.
Compared to prior art, the advantage of the invention is that：The shock absorber of the present invention can adjust height, should by regulation
The height of shock absorber can adjust the height or level of the anechoic room for being provided with the shock absorber, so that the stress of shock absorber is more
Uniformly, extend its service life, strengthen effectiveness in vibration suppression.
Brief description of the drawings
Fig. 1 is the structural representation of adjustable for height shock absorber of the invention.
Fig. 2 is the structural representation of anechoic room mounting dampers of the present invention.
Embodiment
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its accompanying drawing.
As shown in figure 1, a kind of adjustable for height shock absorber, including：Cushion blocking 1, the regulation being rotatably connected with cushion blocking 1
Bar 2 and the containment vessel 3 being connected with adjusting rod 2, the cross sectional shape of cushion blocking 1 are preferably trapezoidal, are allowed to more consolidate and are difficult to incline
Side.The one end of adjusting rod 2 is stretched into from the center of cushion blocking 1, is rotated against for ease of adjusting rod 2 with cushion blocking 1, can be in cushion blocking 1
Plane bearing 9 is set, and the bottom of adjusting rod 2 and plane bearing 9 are matched.The surface of adjusting rod 2 is provided with external screw thread.The section of containment vessel 3
Stepped in what is changed from small to big, stair-stepping section increases its Area of bearing when being to be connected with concrete platform.Containment vessel 3
Top is provided with a cylindric auxiliary section 6, auxiliary section 6 and is provided with the internal thread being engaged with the external screw thread of adjusting rod 2.It is logical
Cross rotation adjusting lever 2, thus it is possible to vary height of the containment vessel 3 on adjusting rod 2, when containment vessel 3 is threaded to minimum, it can
Cushion blocking 1 is contained in containment vessel 3.Interior hexagonal blind hole 4 is offered in the top planes of adjusting rod 2, people can easily make
It is provided with being turned with the T-wrench of hexagon socket head or other spanners on adjusting rod 2, containment vessel 3 and the interior phase of hexagonal blind hole 4
Logical opening 5, convenient wrench is stretched into.
As shown in Fig. 2 its bottom is concrete platform 7 in a kind of anechoic room for being provided with above-mentioned shock absorber, the present embodiment,
It can also be the platform of other materials.The pit 10 for placing the anechoic room is offered on the ground, according to planned in advance
Damper position places shock absorber, and the containment vessel 3 of shock absorber is rotated to extreme lower position to contain cushion blocking 1, then recessed
Casting concrete in hole, concrete is both needed to arrangement separation layer (can be plate or film etc.) with ground and pit surrounding prevents concrete
With pit adhesion after solidification, and it also requires the pipe that arrangement is communicated with opening 5, prevents concrete from blocking opening 5.Treat concrete
After solidification, concrete platform is to build completion, the pipe formation through hole 8 arranged in advance.People are twisted with T-wrench by through hole 8
Hexagonal blind hole 4 in dynamic, so that concrete platform rises, so as to adjust its height, can also adjust level as needed.
Anechoic room (not shown) can be built on concrete platform 7, passes through such a mode, you can the height or water of the whole anechoic room of regulation
It is flat.
The adjustable for height shock absorber of the present invention is simple in construction by screw-driven, easy to use and reliable；3 sections of containment vessel
Face is stepped, and the big bearing capacity of contact area with concrete platform 7 is strong；The anechoic room of the present invention can adjust height or water
Flat, evenly, more preferably, service life is longer for effectiveness in vibration suppression for shock absorber stress.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Person skilled in the art can understand present disclosure and implement according to this, the protection of the present invention can not be limited with this
Scope.Any equivalent change or modification in accordance with the spirit of the invention, should all be included within the scope of the present invention.
