Inside machine, cause entire intercom can not be further continued for using.
Utility model content
The purpose of the utility model is to provide a kind of portable intercom with loudspeaker dust guard, has to cover and raise
Sound device, the advantages of making dust and other impurities be not easily accessible loudspeaker.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of portable intercom with loudspeaker dust guard, including fuselage, function button, communication antenna, channel adjustment
Knob and recording loudspeaker arrangement, the function button are located at fuselage week edge, and the recording loudspeaker arrangement includes being placed in fuselage interior
And the loudspeaker placed towards fuselage front, the loudspeaker are covered with the unilateral shell being fixedly connected with fuselage bottom case, institute outside
Speaker cover is stated equipped with dismountable dust guard, the dust guard includes dustproof cover and for dustproof cover to be fixed on list
Fixed structure on side body.
By using above-mentioned technical proposal, function button, communication antenna, channel adjustment knob and recording loudspeaker arrangement can be with
Realize the basic communication function of intercom, the fuselage of intercom, which is integrated, to be made, so that the overall structure of fuselage is more stable.?
The dust guard set on loudspeaker can cover loudspeaker, be not easily accessible dust and other impurities inside it, extend intercommunication
The service life of machine.Dustproof cover is detachably connected, and keeps the installation and replacement of dustproof cover more convenient.
Further, the square three-way groove with dustproof cover shape adaptation is offered on the unilateral shell, the dustproof cover is long
Degree is equal to the length of loudspeaker, and the two sides of the dustproof cover length direction are extended with fixed strip, the dustproof cover and fixed strip
Longitudinal section is " several " font.
By using above-mentioned technical proposal, the length of dustproof cover and the length of loudspeaker are identical, can be right to the maximum extent
Loudspeaker plays the role of proofing dust and protecting, and dust and other impurities is made to be not easily accessible loudspeaker, and extend loudspeaker uses the longevity
Life.
Further, the two sides of the square three-way groove along its length offer sliding slot, and the fixed structure includes embedding
Telescopic pressure plate and compressed spring in sliding slot, one end of the compressed spring and the slot bottom of sliding slot are contradicted and are connected, the other end
It is fixedly connected with telescopic pressure plate；
When the compressed spring is long in original, the downside of the telescopic pressure plate is abutted with the upside of fixed strip, described to stretch
Contracting pressing plate is abutted close to one end of dustproof cover with the side of dustproof cover.
By using above-mentioned technical proposal, two pieces of telescopic pressure plates can be compressed fixed strip on a speaker, and then will prevent
Dirt lid is fixed in square three-way groove, and two pieces of telescopic pressure plates are abutted by the effect of spring thrust with dustproof cover side, so that flexible pressure
Plate is not easily shifted in the width direction of square three-way groove, promotes connective stability of the dustproof cover in square three-way groove.
Further, the telescopic pressure plate is set as lozenges, the lozenges and flexible pressure far from the side of compressed spring
Plate is acute angle close to the angle that the one side of fixed strip is formed.
It, can be by flexible pressure along lozenges pushing by dustproof cover when dustproof cover is installed by using above-mentioned technical proposal
Plate is pushed into sliding slot, and when dustproof cover is by pushing as loudspeaker upper surface abutting, telescopic pressure plate is no longer by the limit of fixed strip
It acts on and is automatically replied under the effect of the elastic force of compressed spring, until telescopic pressure plate and dustproof cover are inconsistent.
Further, the telescopic pressure plate is fixedly connected with the push plate of inverted L-shaped far from the side of fuselage, and the push plate includes
One end of horizontal segment and vertical section, the vertical section is fixedly connected with telescopic pressure plate far from the side of fixed strip, the vertical section
The other end and horizontal segment close to dustproof cover one end integrally connected；
It is described when the telescopic pressure plate, which is moved to the vertical section into sliding slot, to abut with the two sides in track length direction
It is detached between telescopic pressure plate and the fixed strip of dustproof cover.
By using above-mentioned technical proposal, the setting of push plate makes dustproof cover more aspect in disassembly, needs dustproof cover
When taking out out of square groove, the push plate on telescopic pressure plate can be pushed, be pushed to vertical section and with track length direction two
When the extreme position that side abuts, telescopic pressure plate and fixed strip are detached from, and enough spaces can be provided for dustproof cover and are taken out, are realized dust-proof
The disassembly of lid.
Further, the non-slip mat for increasing friction is equipped with above the horizontal segment.
By using above-mentioned technical proposal, the frictional force between user's hand and push plate can be increased, convenient for users to
Dustproof cover for push plate is pushed to take out.
Further, the length of the telescopic pressure plate and the length of dustproof cover are identical.
By using above-mentioned technical proposal, this design can be such that the contact area between telescopic pressure plate and dustproof cover most closes
Suitable, too small then pressing force is inadequate, excessive, installation even waste material is not easy to, so that telescopic pressure plate makees the compression of dustproof cover
With stronger, whole structural stability is promoted.
Further, the two sides of the dustproof cover width direction are downwardly extending extension board, the extension board and side
The two sides of shape through slot width direction abut.
By using above-mentioned technical proposal, when dustproof cover is in impaction state, extension board and square three-way groove width direction
Two sides abut, and can promote dustproof cover to the leakproofness of fuselage interior loudspeaker.
In conclusion the utility model has the following beneficial effects:
