Part can be inserted into resettlement section.
Preferably, the keeper is provided with snap component, and snap component includes flexible fixture block, and flexible fixture block is set
Put and be provided with bayonet socket in keeper side, the side of the connecting plate, bayonet socket connects with resettlement section, and the flexible fixture block can be caught in institute
State in bayonet socket.
Preferably, the snap component also includes spring, and spring is arranged in the accommodating chamber of keeper, described to stretch
Contracting fixture block is connected with spring, and flexible fixture block can enter in the accommodating chamber.
Preferably, the keeper has multiple, and multiple keepers are raised in the edge part of bottom plate.
Preferably, first lifting arm and the second lifting arm include more linking arms, and adjacent linking arm leads to
Cross the second rotating shaft connection.
The technique effect of the present invention：The height adjustable audio amplifier of the present invention causes elevating mechanism to be combined with audio amplifier, so as to
Moved with together with audio amplifier, while elevating mechanism is extensible or shrinks, and small volume, is easy to carry；In addition, elevating mechanism is consolidated with audio amplifier
It is fixed, with audio amplifier stable connection audio amplifier using effect can be made more preferable in rise and collecting.
Brief description of the drawings
Fig. 1 is the schematic diagram of the height adjustable audio amplifier of the embodiment of the present invention.
Fig. 2 is the schematic diagram of the connecting plate of the embodiment of the present invention.
Fig. 3 is the schematic diagram of the keeper of the embodiment of the present invention.
Embodiment
Below, the substantive distinguishing features and advantage of the present invention are further described with reference to example, but not office of the invention
It is limited to listed embodiment.
As shown in Figure 1 to Figure 3, the height adjustable audio amplifier of the present embodiment includes casing 1, loudspeaker 2 and elevating mechanism 3, institute
State loudspeaker 2 to be arranged on casing 1, the elevating mechanism 3 is connected with casing 1 and positioned at the lower section of casing 1.The casing 1 includes
Bottom plate 11 and connecting plate 12, elevating mechanism 3 are arranged between bottom plate 11 and connecting plate 12.The connecting plate 12 is connected with casing 1,
Elevating mechanism 3 includes the first lifting arm 31, the second lifting arm 32 and gas spring 33, and first, second lifting arm 31,32 intersects
And it is oppositely arranged.First, second lifting arm 31,32 is connected by first rotating shaft 41, first, second lifting arm 31,32 both ends point
It is not fixedly connected with bottom plate 11 and connecting plate 12, the gas spring 33 is arranged between the lifting arm 31 of bottom plate 11 and first.It is above-mentioned
Technical scheme realizes the height regulation of audio amplifier by setting the elevating mechanism with casing one in bottom half.When audio amplifier needs
During rising, bottom plate and connecting plate separation, the thrust provided by gas spring so that first, second lifting arm deploys, so that case
Body rises；If during without using audio amplifier, packing up first, second lifting arm, it is accommodated between bottom plate and connecting plate, so as to
Audio amplifier moves together, is easy to carry.
