Description
Technical field
The utility model is related to communication field more particularly to audio video transmission equipment.
Background technology
Chinese patent discloses a kind of mobile emergency bidirectional audio-video transmission device, the patent No.
Zl201220743103.3 is described：A kind of mobile emergency bidirectional audio-video transmission device, including equipment box, Yi Jishe
Put display screen, public address sound equipment, video acquisition device, audio collecting device, codec, power module and nothing in equipment box
Line communication module, the codec connect respectively display screen, public address sound equipment, video acquisition device, audio collecting device and
Wireless communication module, the power module connect respectively display screen, public address sound equipment, video acquisition device, audio collecting device,
Codec and wireless communication module.The power module includes lithium battery group, hand-operated electric generator and overcurrent protection
Device, the hand-operated electric generator access lithium battery group by current overload protector.
Above-mentioned technical proposal has problems in that：The hand-operated mechanism of its hand-operated electric generator is only a crank, and structure is simple
Single but rotate hard, environment needs to save the required electricity of transmission of video and needs to consume the more muscle power of user outdoors.
Invention content
In view of the deficiencies of the prior art, the utility model provides a kind of audio video transmission easy to use that can save muscle power and sets
It is standby.
The technical solution of the utility model is：
Audio video transmission equipment, it is characterised in that：It includes equipment box, and the equipment box is equipped with hand-operated electric generator, institute
The shaft for stating hand-operated electric generator sets and crank is provided in shaft upward, there are two the crank both ends are set straight up
Column, the equipment box bottom are provided with a containing box, a rubber block are filled in the containing box, and the rubber block is equipped with two
A cylinder shape groove, the cylinder shape groove are embedded in clump weight, and the clump weight is piece of stainless steel, and the clump weight is cylinder
Shape cuts the column that bottom is corresponded on crank and is provided with bearing, and the storage box outer wall is arranged with an aluminium alloy lantern ring, the work of lantern ring
With in addition to that can also be connected with banding containing box with other than rubber block by conducting wire with the signal transmitting and receiving mechanism in equipment box, play
The effect of loop aerial.
Specifically, the equipment box further includes display screen, public address sound equipment, video acquisition device, audio collecting device, compiles solution
Code device, power module and wireless communication module, the codec connect display screen, public address sound equipment, video acquisition dress respectively
It puts, audio collecting device and wireless communication module, the power module connect display screen, public address sound equipment, video acquisition respectively
Device, audio collecting device, codec and wireless communication module, the power module includes lithium battery group, hand-rail type is sent out
Motor and current overload protector, the hand-operated electric generator access lithium battery group by current overload protector.
Specifically, the wireless communication module passes through connecting sleeve of wire ring.
Specifically, detachable installation is used between the shaft of the hand-operated electric generator and hand-operated electric generator main body.
The application method of the utility model：
1) clump weight out of rubber block is taken out, be then inserted into the column of crank in the bearing of clump weight；
2) one of clump weight rotation is held so as to which shaft be driven to rotate, since the inertia and clump weight of clump weight are
Rotatable cylinder, and the power of shaft rotation is maintained to be less than arm, the power of shaft is shaken by crank, therefore strength can be saved.
The beneficial effects of the utility model are：By the inertia of clump weight convenient for maintaining shaft velocity of rotation, use is smaller
Strength can ensure the normal rotation of shaft, greatly reduce the labor intensity of user；For banding rubber block lantern ring also
External antenna can be used as, plays the role of enhancing wireless communication signal.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure, 1, equipment box；2nd, shaft；3rd, crank；4th, column；5th, rubber block；6th, lantern ring；7th, clump weight.
