Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See Figures 1 to 5 As shown, the portable audio device provided by the present invention includes a speaker 1, a handle 3, and a universal wheel 5. A handle groove is provided on the back of the speaker 1, and the handle 3 is slidably sleeved inside the handle groove. Two sets of limit sliders 19 are fixedly connected to both sides of the handle 3. The outer walls of the two sets of limit sliders 19 are slidably sleeved inside the speaker 1.

[0026] A storage compartment is provided at the bottom end of the speaker 1, and two sets of roller storage mechanisms are movably sleeved inside the storage compartment, and the two sets of roller storage mechanisms are arranged axially symmetrically. The two sets of roller storage mechanisms are fixedly connected to two sets of universal wheels 5, and transmission devices are provided on the opposite sides of the two sets of roller storage mechanisms, and the end of the transmission device is fixedly connected to the bottom end of the handle 3.

When the speaker needs to be moved to a different location, just pull the handle and the roller will automatically rise, achieving the effect of quick transportation.

[0028] The roller storage mechanism includes two sets of connecting rods 2, both ends of which are movably connected to the speakers 1. The outer walls of the two sets of connecting rods 2 are fixedly connected to four sets of connecting rings 4. The four sets of connecting rings 4 are located at the bottom end of the speaker 1 in a square four-corner array, and two sets of connecting rings 4 are arranged opposite to the other two sets of connecting rings 4. The sides of the connecting rings 4 are fixedly connected to universal wheels 5.

[0029] The outer walls of the two groups of connecting rotating rods 2 are fixedly connected with a rack 6, the top of the rack 6 is engaged with a tooth plate 18, and the opposite sides of the two groups of tooth plates 18 are respectively fixedly connected with a group of hinge blocks 12, and the interior of the hinge blocks 12 is hinged with one end of a transmission rod 2 11, and the other end of the transmission rod 2 11 is hinged with a transmission rod 10, and the opposite sides of the two groups of transmission rods 10 are fixedly connected with a connecting rod 20, and the top of the connecting rod 20 is movably connected to the top of the speaker 1.

[0030] The top end of the hinge block 12 is slidably sleeved with a second slide plate 13 , and the top end of the second slide plate 13 is fixedly connected to the bottom end of the speaker 1 .

[0031] By rotating the connecting rod 20 at the bottom of the speaker 1, the transmission rods 10 on both sides are pulled to rotate with it as the center of the circle, and the transmission rods 2 11 on both sides are pulled to hinge and rotate with the hinge block 12, so that the two groups of hinge blocks 12 slide inside the slide plate 2 13, and the bottom end of the hinge block 12 engages with the rack 1 6 to drive the connecting rotating rod 2 to rotate at the bottom end of the speaker 1. At the same time, the connecting ring 4 fixedly connected to the surface of the connecting rotating rod 2 drives the universal wheel 5 to rotate synchronously, so that the universal wheel 5 contacts the ground, so that the bottom end of the speaker 1 is separated from the ground, and the universal wheel 5 is used as the supporting point to contact the ground, thereby facilitating the movement of the speaker 1. On the contrary, when the universal wheel 5 is normally stored, the bottom end of the speaker 1 contacts the ground, and the flat bottom has a large friction with the ground, so that it is not easy to overturn.

[0032] The transmission device includes a connecting rope 16, one end of the connecting rope 16 is fixedly connected to the bottom end of the handle 3, the other end of the connecting rope 16 is fixedly connected to the outer wall of the connecting plate 2 17, the front of the connecting plate 2 17 is fixedly connected to the tooth plate 21, the front of the connecting plate 2 17 is fixedly connected to the limit bar 7, the tooth plate 2 21 is provided on the opposite side of the limit bar 7 with a rack 2 9, and the outer wall of the tooth plate 21 is engaged with the rack 29, and the inner wall of the rack 29 is fixedly connected to the connecting rod 20.

[0033] The back of connecting plate 2 17 is fixedly connected to one end of two sets of springs 14, the other end of spring 14 is fixedly connected to connecting plate 15, the outer wall of connecting plate 15 is fixedly connected to the outer wall of slide plate 1 8, and the top of slide plate 1 8 is fixedly connected to the speaker 1.

[0034] The inner wall of one set of the chute plates 1 8 is slidably sleeved with the tooth plate 2 21 , and the inner wall of the other set of the chute plates 1 8 is slidably sleeved with the limit strip 7 .

[0035] When the speaker 1 needs to be moved, the handle 3 on the back of the speaker 1 is pulled, and the handle 3 slides on the inner wall of the speaker 1. The bottom end of the handle 3 pulls the connecting plate 2 17 through the connecting rope 16 connected to the bottom end to slide toward the rear end inside the slide plate 1 8, further driving the tooth plate 2 21 to engage with the rack 2 9, so that the connecting rod 20 rotates at the bottom end of the speaker 1, driving the roller storage mechanisms on both sides to flip, and setting the limit bar 7 to make the tooth plate 21 slide stably inside the slide plate 1 8 to keep the transmission device transmission It is more stable. After the movement of the speaker 1 is completed, the handle 3 is put back into the interior of the speaker 1. Under the influence of the elastic potential energy of the spring 14, the connecting plate 2 17 is pushed to the front end, and then the tooth plate 2 21 is pushed to reset, and further the roller storage mechanisms on both sides are driven to flip the rollers back to the bottom inner side of the speaker 1, so that the rollers can be automatically pulled by pulling the handle 3 or canceling the pulling of the handle 3, and flexibly stored and turned out. The rollers are automatically lifted, eliminating additional operating steps and improving the convenience and efficiency of use.
