DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example:

[0023] like Figure 1-5As shown, a portable speaker includes a speaker body 100, wherein universal wheels 101 are provided at the four corners of the lower end of the speaker body 100, and a storage mechanism is provided between the universal wheels 101 and the speaker body 100;

[0024] The storage mechanism includes a storage groove 200. The four corners of the lower end of the speaker body 100 are provided with storage grooves 200. The upper end of the storage groove 200 is embedded with an electric telescopic rod 201. The lower end of the electric telescopic rod 201 is fixedly connected to the center of the upper end of the universal wheel 101. A closed groove 202 is provided on the side of the lower end of the storage groove 200. The inner wall of the storage groove 200 and the upper wall of the closed groove 202 are jointly provided with an L-shaped linkage groove. A hydraulic bag 203 is provided inside the linkage groove. The upper and lower ends of the hydraulic bag 203 are fixedly equipped with linkage blocks 204. A linkage support rod 205 is provided between the upper linkage block 204 and the upper end of the universal wheel 101. A closed plate 206 is slidably installed inside the closed groove 202. The lower linkage block 204 is fixedly connected to the upper end of the closed plate 206. A return rope 207 is connected between the lower part of the electric telescopic rod 201 and the closed plate 206.

[0025] The universal wheel 101 facilitates the movement of the speaker body 100. The storage groove 200 is used to carry and store the universal wheel 101. The electric telescopic rod 201 is used to carry and drive the universal wheel 101 to enter and extend out of the storage groove 200. The closed groove 202 is used to carry the closed plate 206. The closed plate 206 is used to close the storage groove 200 after the universal wheel 101 enters the storage groove 200, so that the dirt and dust attached to the universal wheel 101 will not fall outside the storage groove 200. The hydraulic bag 203 is made of soft material and can be compressed and deformed. It contains liquid inside, which is used to push the universal wheel 101 out when the electric telescopic rod 201 pushes the universal wheel 101 to extend. The hydraulic bag 203 pushes the closing plate 206 in linkage, so that the storage slot 200 is opened. The linkage block 204 and the linkage support rod 205 are used to respectively connect the hydraulic bag 203, the universal wheel 101 and the closing plate 206. The return rope 207 is an elastic rope, which is used to pull back the closing plate 206 when the electric telescopic rod 201 drives the universal wheel 101 to enter the storage slot 200. A ring for fixing the position of the return rope 207 is provided at the lower end of the storage slot 200 on the side opposite to the closing slot 202, to ensure that the closing plate 206 can be pulled and reach the other side of the storage slot 200, thereby ensuring the opening and closing of the closing plate 206.

[0026] The linkage groove is cylindrical, and the hydraulic bag 203 is arranged to match the shape of the linkage groove, so that the hydraulic bag 203 will not fall out of the linkage groove.

[0027] The inner diameter of the upper linkage groove inside the storage groove 200 is larger than the inner diameter of the lower linkage groove inside the closed groove 202, so that when the universal wheel 101 is pushed out, the closed plate 206 is pushed to a greater extent, so that the closed plate 206 opens faster.

[0028] The hydraulic bag 203 is fixedly arranged at the L-shaped inflection point of the linkage groove to stabilize the position of the hydraulic bag 203 .

[0029] A retractable handle 102 is provided on the rear side of the speaker body 100 to facilitate moving the speaker body 100 .

[0030] Working principle: When the universal wheel 101 is unfolded, the electric telescopic rod 201 is unfolded downward and pushes out the universal wheel 101, and the universal wheel 101 moves downward, driving the linkage support rod 205 to move downward, and the linkage support rod 205 pushes the linkage block 204 to move downward, thereby pushing and compressing the hydraulic bag 203, and the liquid in the hydraulic bag 203 is squeezed to the lower part, thereby pushing the closing plate 206 to move so that the lower end of the storage slot 200 is opened;

[0031] When the universal wheel 101 is recovered, the electric telescopic rod 201 contracts, driving the universal wheel 101 to move upward into the storage groove 200. The electric telescopic rod 201 contracts and moves upward to pull the return rope 207. The return rope 207 pulls the closing plate 206 back to the lower end of the storage groove 200 and squeezes the hydraulic bag 203 at the same time, so that the liquid in the hydraulic bag 203 flows back to the upper part of the hydraulic bag 203.

[0032] By providing a storage mechanism, the universal wheel 101 can be hidden and stored, and at the same time, the dust and dirt on the universal wheel 101 from the outside ground will not fall out of the storage groove 200, so as not to pollute other items or storage space in the storage place.

[0033] 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 relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
