Description
Technical field
This utility model relates to audio amplifier field, particularly to a kind of packaged type audio amplifier.
Background technology
In daily life, outdoor performance, in the occasion such as square dance, Mobile loudspeaker box is seen everywhere；But its field used
Closing different with indoor stage, it is earth that outdoor occasion often runs into the especially outdoor occasion of the rough situation in bottom surface
Place, and existing open air may move audio amplifier and mostly has a castor, but its height non-adjustable, this audio amplifier end out of doors
Irregular place, face is often not easy to place, and i.e. enables and finds local placement the shape that indivedual castors are unsettled the most easily occur
State, audio amplifier is placed unstable, and along with vibrations when of audio amplifier work, audio amplifier is easy to move or rock, the most then affect
Tonequality, heavy then audio amplifier slips to the place that more tilts and topples over damage audio amplifier.
Utility model content
In order to solve the problems referred to above, this utility model provides a kind of audio amplifier, audio amplifier castor and audio amplifier bottom surface to use screw thread even
Connect, and by Worm Wheel System, be screwed into the length of audio amplifier bottom surface with hand cranking structure regulation castor stud thus finely tune castor
Flexible height.
According to an aspect of the present utility model, it is provided that a kind of audio amplifier, it is characterised in that including: audio amplifier body, install
Universal wheel in described audio amplifier body bottom surface；Wherein, described universal wheel includes wheel carrier, is installed on the wheel of described wheel carrier, described
The wheel disc of wheel top of the trellis is fixed with a stud, and corresponding to described stud, audio amplifier body bottom surface is installed universal wheel position and is provided with phase
The screwed hole answered, the other end end of described stud is vertically and fixedly provided with a thick worm gear, rotatable with the worm screw that thick worm gear is meshed
It is fixed on audio amplifier body spacing by the catch that is arranged on described thick worm gear, outside worm screw, stretches in one end of this body side surface of audio amplifier
It is bent into Z-type and forms handle；Universal wheel is fixed on the corresponding screw in audio amplifier bottom surface by the threaded engagement of stud, by thick worm gear
Coordinate transmission with worm screw, make stud rotate by crank handle, thus regulate the height of universal wheel, thus, it is possible to have regulation
The effect of audio amplifier castor height.
In some embodiments, described handle is provided with anti-slip veins.Thus, it is possible to have anti-skidding effect.
In some embodiments, described thick worm gear, worm screw, stud uses plastic material to be fabricated by.Thus, it is also possible to
There is cost-effective being easy to manufacture, alleviate the effect of quality.
Accompanying drawing explanation
Fig. 1 is the audio amplifier schematic diagram of this utility model one embodiment；
Fig. 2 is audio amplifier Universal wheel structure schematic diagram shown in Fig. 1；
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Fig. 1～2 show schematically show the audio amplifier according to a kind of embodiment of the present utility model.As it can be seen, this dress
Put and include: audio amplifier body 10, be installed on the universal wheel 20 of described audio amplifier body 10 bottom surface；Wherein, described universal wheel 20 includes wheel
Frame 207, is installed on the wheel 201 of described wheel carrier 207, and described wheel carrier 207 top wheel disc is fixed with a stud 202, corresponds to
Described stud 202, audio amplifier body 10 bottom surface installs universal wheel 20 position and is provided with corresponding screwed hole 208, described stud 202 another
One end end is vertically and fixedly provided with a thick worm gear 205, and the worm screw 204 being meshed with thick worm gear 205 is rotatably affixed at audio amplifier body
10 and spacing by the catch 2041 that is arranged on described worm gear 204, the one end stretching in audio amplifier body 10 side outside worm screw 204 is curved
Being converted into Z-type and form handle 206, handle (206) is provided with anti-slip veins, thick worm gear 205 described above, worm screw 204, stud 202
Employing plastic material manufactures.
As in figure 2 it is shown, the wheel disc that the wheel 201 of universal wheel 20 and wheel carrier 207 are articulated with stud 202 one end (is not marked in figure
Note), thus, as general universal wheel, the wheel 201 of universal wheel 20 and wheel carrier 207 can be freely along the axis of stud 202
The rotation of 306 degree of direction；The audio amplifier bottom surface portions installing universal wheel 20 is provided with the screwed hole 208 consistent with stud 202；Universal wheel 20
Coordinated with screwed hole 208 by stud 202 and be arranged on audio amplifier；Stud 202 ending vertical is fixed with a thick worm gear 205, accordingly
Worm screw one end stretch out audio amplifier and become Z-type and form handle 206；When swinging handle 206 then worm screw 204 rotates, thus drive thick snail
Wheel 205 rotation, owing to thick worm gear 205 is vertically and fixedly provided with a stud 202, therefore stud 202 can rotate, so that stud 202 is at spiral shell
Move axially in hole 208, thus the height of folding and unfolding universal wheel 20, namely reach to finely tune the purpose of audio amplifier castor height so that it is reach
To the state of balance, when all of universal wheel 20 is all in stud 202 end when, it is highly consistent；Now, due to stud
202 is affixed with thick worm gear 205, therefore the when that stud 202 moving up and down, thickness worm gear 205 is the most mobile, for preventing thick worm gear 205 from moving
Dynamic away from departing from the when of worm screw 204 and the engaging of worm screw 204, therefore the thickness of thick worm gear 205 is thicker, its concrete thickness is regarding universal
Depending on the height that wheel 20 can regulate.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art,
On the premise of creating design without departing from this utility model, it is also possible to making some deformation and improvement, these broadly fall into this practicality
Novel protection domain.
