The slide rod 144 and the damping ring 17 slide up and down to match each other. A through slot 15 is provided on the upper side of the slide bar 144, a locking block 151 is slidably mounted on the inner side of the through slot 15, a second spring 1511 is fixedly mounted between the locking block 151 and the through slot 15, a locking slot 152 matching the locking block 151 is provided on the upper side of the support column 14, and limiting slots 171 are provided on the left and right sides of the slide slot 141, the locking block 151 and the limiting slot 171 are matched with each other in sliding up and down, an adjusting block 153 is slidably mounted on the upper side of the support column 14, the lower side of the adjusting block 153 is matched with the locking slot 152 in sliding left and right, and the adjusting block 153 is threadedly rotatably connected with a screw 154, wherein the damping ring 17 cooperates with the first spring 145 to play a buffering role, reduce the shaking of the box body 11 when moving on an uneven road surface, and protect the electrical components inside the audio body 1;

[0029] There are two locking blocks 151 and two adjusting blocks 153, and the two adjusting blocks 153 are respectively slidably assembled on the left and right sides of the support column 14. There are two locking grooves 152, and the two locking grooves 152 are respectively located on the left and right sides of the support column 14. The two locking blocks 151 are respectively slidably assembled on the inner sides of the two locking grooves 152. The screw rod 154 is a bidirectional threaded rod, and the two adjusting blocks 153 are respectively threadedly rotatably connected with the two sides of the screw rod 154.

[0030] like Figure 4 As shown, the adjustment assembly includes a rotating rod 16, an adjustment slot 161 is opened in the middle of the lower side of the box body 11, and the rotating rods 16 are rotatably mounted on both ends of the adjusting slot 161. The rotating rod 16 passes through the lower side of the box body 11 and is fixedly connected to the screw 154. The rotating rod 16 is sleeved with a torsion spring 162, and the two ends of the torsion spring 162 are respectively fixedly connected to the adjustment slot 161 and the rotating rod 16. A pedal 163 is fixedly connected between the two rotating rods 16, and an oblique connecting plate 18 is fixedly mounted on the opposite ends of the two rotating rods 16 in the same group, and the pedal 163 is fixedly assembled between the two oblique connecting plates 18;

[0031] like Figure 3-4As shown, an assembly groove 2 is provided at the lower side of the front end of the box body 11, a servo motor 21 is fixedly installed inside the assembly groove 2, an assembly rod is rotatably installed inside the assembly groove 2, a dustproof cloth 122 is wound around the assembly rod, an electric wire take-up device 22 is fixedly installed on the upper side of the box body 11, the pull wire of the electric wire take-up device 22 is fixedly connected to the upper end of the dustproof cloth 122, a collection box 23 is fixedly installed on the front side of the box body 11, a sealing cover 231 is installed on the front side of the collection box 23, a scraper 24 is provided on the rear side of the collection box 23, a shielding cover 25 is provided on the upper side of the collection box 23, and the shielding cover 25 is located in front of the scraper 24.

[0032] When moving the audio body 1, it is only necessary to push and pull the handle 13 connected to the box body 11 forward and backward to realize the movement of the audio body 1. After moving the box body 11 to the specified position, the operator only needs to push the box body 11 downward to make the slide bar 144 slide toward the upper side of the slide groove 141. In this way, the locking block 151 on the upper side of the slide bar 144 can move into the locking groove 152. The locking block 151 prevents the first spring 145 from driving the roller 143 to move downward. At this time, since the roller 143 is stored in the storage groove 142, the box body 11 is supported by the support column 14. The four support columns 14 make the support of the box body 11 stable to prevent it from sliding randomly on the wet ground. Then, the dustproof cloth 122 is pulled open to use the audio body 1, and the audio body 1 is connected and controlled through the position of the window 12;

[0033] When the audio body 1 is no longer needed, first lift the roller 143 on the front side of the box 11, then step on the pedal 163 to rotate the rotating rod 16, and the rotation of the rotating rod 16 can drive the screw 154 to rotate. The screw 154 can drive the adjustment block 153 to move during the rotation process, thereby pushing the locking block 151 to unlock. After unlocking, the roller 143 will be reset by the first spring 145. In the same way as above, lift the roller 143 on the rear side of the box 11 to release all the rollers 143, and then the box 11 can be moved by the rollers 143.

[0034] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
