The utility model loudspeaker of electric powered steering type comprises: audio amplifier is characterized in that: audio amplifier is a sector structure, and promptly the back of audio amplifier is an arcwall face; One is used to install the support body of audio amplifier, and audio amplifier is installed on the support body by rotating shaft, and audio amplifier interarea and support body surface are on a plane; But be provided with the transmission mechanism that a transmission audio amplifier rotates around the axis between support body and audio amplifier.
Described support body is the cavity shape structure frame or the shaped as frame structure-steel framing that the sector structure audio amplifier can be embedded in it.
The design principle of the utility model loudspeaker of electric powered steering type is: utilize transmission mechanism to impel to be installed in the engaged transmission of the sector structure audio amplifier back arcwall face upper rack on the support body to be installed in audio amplifier in the rotating shaft, audio amplifier is rotated under the drive of motor, and the loudspeaker of the audio amplifier of realization point to and can regulate at setting range.Point to unadjustable defective to change the traditional structure speaker.
The utility model loudspeaker of electric powered steering type only needs the motor by the control transmission mechanism under not mobile state, can change the sensing of loudspeaker, and therefore, it almost can various angles be furnished or hang, and adapts to the installation requirement of different places.The audio amplifier of this structure also is applicable on the ceiling furred ceiling and installs, and points to the defective that can not change to solve traditional smallpox loudspeaker.This loudspeaker of electric powered steering type design science, rational in infrastructure, easy to use, effective, applied widely, be a kind ofly can satisfy various installation requirements, the novel audio amplifier that applicability is fabulous.
The utility model loudspeaker of electric powered steering type by the motor of automatic control equipment regulation and control loudspeaker of electric powered steering type, is realized the automatic change of the loudspeaker sensing of audio amplifier as if joining and corresponding automatic control equipment.
The concrete structure of the utility model loudspeaker of electric powered steering type is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the structural representation of loudspeaker of electric powered steering type.
Embodiment
Embodiment: can be clear that from Fig. 1 this is a kind of loudspeaker of electric powered steering type of installing on the smallpox furred ceiling that is applicable to, is made up of audio amplifier 1, shaped as frame structure-steel framing 2 and transmission mechanism 3, described audio amplifier 1 is a sector structure, and promptly the back of audio amplifier 1 is an arcwall face 12; The arcwall face 12 of audio amplifier 1 is provided with arc-shaped rack 38; Described shaped as frame structure-steel framing 2 is provided with a window 21 that supplies audio amplifier 1 interarea to stretch out, shaped as frame structure-steel framing 2 is provided with the installing hole 22 that is used for its installing and locating, the transmission mechanism 3 that is made of motor 31, driving gear 32, the driven gear 35,36 that is installed in power transmission shaft 34 two ends and bearing pedestal 37 and arc-shaped rack 38 is installed by support 4 in the back of shaped as frame structure-steel framing 2, described power transmission shaft 34 is installed in parallel in shaped as frame structure-steel framing 2 backs by bearing pedestal 5 and motor 31, is installed in driven gear 35 engagements on driving gear 32 and the power transmission shaft 34 on 31 in the motor; One end of described audio amplifier 1 is installed on the shaped as frame structure-steel framing 2 by rotating shaft 13, and the interarea of audio amplifier 1 and shaped as frame structure-steel framing 2 surfaces are on a plane, and audio amplifier 1 can 13 rotate around the shaft.The driven gear 35,36 at power transmission shaft 34 two ends of transmission mechanism 3 respectively with arc-shaped rack 38 engagement at audio amplifier 1 back, the rotation of the motor 31 of transmission mechanism 3 can drive arc-shaped rack 38 with 35,36 engagements of rotation axis 34 two ends driven gears and can drive audio amplifier 1 and 13 rotate around the shaft.
Described transmission mechanism is provided with and can prevents that audio amplifier from inwardly rotating the limit switch 39 of position, this limit switch 39 is installed in transmission mechanism side frame body window 21 lower edges, when audio amplifier 1 inwardly rotates above desired location under transmission mechanism drives, this limit switch 39 can contact with 1 frame of audio amplifier, cut off motor 31 power supplys of transmission mechanism 3, make audio amplifier 1 stop to continue inside rotation.
This audio amplifier also is provided with the limit adjusting mechanism 5 of a scalable audio amplifier 1 outside rotational angle, described limit adjusting mechanism 5 is by the slide rail 51 that is installed in shaped as frame structure-steel framing 2 backs, the movable slide block 52 that is installed on the slide rail 51 that cooperates, be installed in the limit switch 53 on the slide block 52 and be arranged on the stepped spacing shelves 14 in audio amplifier 1 back and constitute, described slide block 52 can horizontally slip on slide rail 51, the limit switch 53 that is installed on the slide block 52 can contact with the stepped spacing shelves 14 in audio amplifier 1 back, when slide block 52 is allocated to slide rail 51 left ends, limit switch 53 on it can contact with the 1st grade of the spacing shelves 14 of ladder, audio amplifier 1 this moment 13 angle minimums of rotating around the shaft, by regulating slide block 52 upper limit position switch 53 and stepped spacing shelves 14 different gear contacts, the scope of may command audio amplifier 1 outside rotational angle.
Since at the motor 31 of this audio amplifier transmission mechanism 3 under the dump state, audio amplifier 1 may continue outside rotation because of deadweight, especially be installed in this structure audio amplifier on the ceiling furred ceiling, the deadweight of audio amplifier 1 can make it continue around the shaft to glide under unpowered effect.Be to stop the downslide under motor 31 dump states of audio amplifier 1, cause audio amplifier 1 excessively outwards rotation may cause the dislocation of 38 of driven gear 35,36 and arc-shaped racks.Audio amplifier 1 back arc-shaped rack 38 is not held and is provided with one and can prevents that it from outwards rotating the spacing insurance protruding 14 of dislocation, when this spacing insurance protruding 14 is arranged on its downslide of audio amplifier and puts in place, can be affiliated to being installed in support body transmission mechanism 3 side power transmission shafts 34, continue outwards to rotate to stop audio amplifier 1.
