[ detailed description ] embodiments

The invention will be further described with reference to the accompanying drawings:

as shown in fig. 5, the supporting rod 4 is fixed on the lower speaker 41, and the tray is installed at the bottom of the upper speaker 40, so that the upper speaker 40 is placed above the supporting rod 4 and the supporting rod 4 is inserted into the cavity 13 of the tray.

As shown in fig. 1 and 5 to 8, the tray cap for multi-angle adjustment of a sound box comprises a tray body 10, wherein a tapered cavity 13 for inserting the support rod 4 and swinging inside is formed in the tray body 10, a first supporting surface 11 and a second supporting surface 12 for supporting the support rod 4 are arranged on the inner top of the cavity 13, the first supporting surface 11 is connected with the second supporting surface 12, and a reflex angle a is formed between the first supporting surface 11 and the second supporting surface.

The toper cavity 13 of tray cap 1 has given the wobbling space of bracing piece 4 to make bracing piece 4 can transition smoothly to withstanding second holding surface 12 from withstanding first holding surface 11, form major angle A between first holding surface 11 and the second holding surface 12 and enable bracing piece 4 when withstanding first holding surface 11 and turn into and withstand second holding surface 12, the up end of bracing piece 4 changes into second holding surface 12 of laminating from first holding surface 11 of laminating completely, thereby make the audio amplifier 40 on upper strata can take place corresponding angle change and then obtain different hearing effects when using the audio amplifier to put sound outward.

The multifunctional angle adjusting tray shown in fig. 1 to 8 comprises a tray cap 1, wherein the tray cap 1 comprises a tray body 10, a conical cavity 13 which is used for inserting the supporting rod 4 and swings inside is formed in the tray body 10, a first supporting surface 11 and a second supporting surface 12 which are used for supporting the supporting rod 4 are arranged on the inside top of the cavity 13, the first supporting surface 11 and the second supporting surface 12 are connected with each other, a reflex angle A is formed between the first supporting surface 11 and the second supporting surface 12, and an adjusting structure which can change the supporting surface supported by the supporting rod 4 is connected to the bottom of the tray body 10 and located below the cavity 13. The adjusting structure comprises an adjusting disc 2 which is rotatably connected to the bottom of the tray body 10 and located at the lower end of the cavity 13, wherein an eccentric through hole 22 is formed in the adjusting disc 2 and is used for enabling the supporting rod 4 to penetrate and limiting the supporting rod 4 to swing, and a lug 23 which is used for assisting a user to rotate the adjusting disc 2 through fingers is arranged on two sides of the eccentric through hole 22.

When the finger rotates the adjusting disc 2 through the force-assisted convex block 23, the supporting rod 4 is fixed, the adjusting disc 2 rotates eccentrically around the fixed supporting rod 4 passing through the eccentric through hole 22, so that the supporting rod 4 rotates from propping against the first supporting surface 11 to propping against the second supporting surface 12, and the angle of the upper layer of the sound box 40 is changed, so that the auditory effect is changed when the sound box is used for playing sound outside.

The bottom of the tray body 10 is provided with a groove 14 below the cavity 13, the groove 14 can be used for placing the adjusting disc 2, a positioning clamping groove 15 is arranged in the groove 14, and two sides of the adjusting disc 2 are provided with elastic clamping arms 24 which can be matched with the positioning clamping groove 15 to provide positioning when the adjusting disc 2 rotates.

The utility model discloses an adjusting disk 2 is than the lower port of toper cavity 13 greatly than recess 14 little, we can put adjusting disk 2 in recess 14 when the equipment, and recess 14 is equipped with 2 positioning channel section 15 that are 180 distributions for circular recess in recess 14 and supplies adjusting disk 2 to carry out the positioning adjustment to the tray, elastic clamp arm 24 just mutually supports with positioning channel section 15 on the tray cap 1 when rotatory adjusting disk 2 is to the assigned position again because 2 positioning channel section 15 on the above-mentioned recess 14 are 180 distributions so that elastic clamp arm 24 mutually supports with positioning channel section 15 again when adjusting disk 2 is rotatory 180 back elastic clamp arm 24, when elastic clamp arm 24 and positioning channel mutually supports, thereby elastic clamp arm 24 can block positioning channel section 15 and prevent that adjusting disk 2 from rotating by oneself and upper audio amplifier 40 from rocking the phenomenon appears.

6 bolt through holes 16 are arranged around the periphery of the groove 14, a bottom plate 3 which is fixedly connected with the lower end of the tray body 10 and limits the adjusting plate 2 in the groove 14 of the tray cap 1 is arranged on the lower end of the tray body, and a through hole 31 for the supporting rod 4 to pass through is arranged on the bottom plate 3. The through hole 31 is a round hole which is smaller than the adjusting disk 2 and can expose the lug 23 on the adjusting disk 2 and the indicating lug 21 through the through hole 31. The lower end face of the chassis 3 is provided with a second indication bump 32, and the periphery of the through hole 31 is surrounded by 4

chassis bolt holes

33 and 2 hoisting screw holes 34 for installing hoisting lugs to be matched with the bolt through holes 16 on the tray cap 1.

Through the bolt through-hole 16 and the chassis bolt hole 33 that mutually support, with the lower extreme of bolt with chassis 3 fixed connection at tray cap 1, again because adjustment disk 2 is greater than cavity 13 port and is less than recess 14, through-hole 31 for being less than adjustment disk 2 and can expose lug 23 on adjustment disk 2 and the round hole of instructing lug 21 through-hole 31, so chassis 3 can restrict adjustment disk 2 in recess 14, expose lug 23 through-hole 31 and supply the finger to borrow the rotatory adjustment disk 2 of power. When the indication projection 21 on the adjusting disc 2 is aligned with the second indication projection 32 on the chassis 3, the elastic clip arm 24 on the adjusting disc 2 is exactly matched with the positioning clip groove 15 on the tray cap 1, at this time, the support rod 4 is pressed against the first supporting surface 11, and because the 2 positioning clip grooves 15 on the groove 14 are distributed in 180 degrees, after the adjusting disc 2 rotates 180 degrees, the elastic clip arm 24 is matched with the positioning clip groove 15 again, but at this time, the support rod 4 is pressed against the second supporting surface 12, when people rotate the adjusting disc 2, the indication projection 21 and the second indication projection 32 can well indicate whether the elastic clip arm 24 is matched with the positioning clip groove 15, so as to prevent the upper sound box 40 from shaking caused by the self-rotation of the adjusting disc 2 due to the improper rotation of the adjusting disc 2 when the angle of the sound box is adjusted, the 2 hoisting screw holes 34 are distributed in 180 degrees through the center of the through hole 31, when the sound box is not placed flatly, install the hoist and mount hangers through hoist and mount screw hole 34 on chassis 3 and can install the utility model discloses the audio amplifier hoist and mount of tray get up and prevent because of this audio amplifier takes place to fall down because of placing on the place of unevenness.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
