[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-6 A portable wireless speaker includes a speaker housing 1. Multiple anti-collision pads 2 are provided around the four ends of the speaker housing 1. The multiple anti-collision pads 2 are installed around the four ends of the speaker housing 1 by a bolt assembly. The anti-collision pads 2 are made of rubber. The bolt assembly includes bolts and threaded holes for threading two parts together, which facilitates the replacement of damaged anti-collision pads 2 by the operator. By setting multiple anti-collision pads 2, the damage to the speaker housing 1 during transportation is reduced, and the stability of the device during operation is ensured.

[0026] Four casters 8 are fixedly arranged in a circle at the bottom of the speaker housing 1, and two fixing brackets 6 are symmetrically fixed on both sides of the speaker housing 1. Fixing rods 7 are fixedly arranged on the inner side wall of the fixing brackets 6. Through the cooperation of fixing rods 7 and fixing brackets 6, it is convenient for operators to adjust the position of the speaker housing 1, reduce the labor intensity of operators when moving it, and improve the work efficiency of moving the speaker housing 1.

[0027] The speaker housing 1 has four symmetrical storage slots 5 on both sides, one above the other. Each storage slot 5 has a handle 4. A first rotating shaft 3 is rotatably mounted on the inner wall of the first storage slot 5. The outer wall of the first rotating shaft 3 and the end of the handle 4 are coaxially and fixedly connected. The storage slots 5 and the handles 4 fit together. Through the cooperation of the first rotating shaft 3 and the handles 4, it is convenient for operators to lift the speaker when encountering stairs or other objects. The handles 4 on both sides reduce the time and labor intensity of the operator when lifting the speaker, and improve the efficiency of the lifting. At the same time, the first storage slots 5 provide storage space for the four handles 4 on both sides, making it convenient for the operator to lift the speaker housing 1 and ensuring the concealment of the four handles 4.

[0028] The outer end face of the speaker housing 1 is provided with a second storage slot 14, and a pull rod 13 is provided in the second storage slot 14. Two fixed shafts 10 are symmetrically fixedly arranged on the inner side wall of the second storage slot 14. A second rotating shaft 9 is coaxially rotatably arranged between the two fixed shafts 10. The outer side wall of the second rotating shaft 9 and the end of the pull rod 13 are coaxially fixedly connected, and the second storage slot 14 and the pull rod 13 fit together. Through the mutual cooperation of the second rotating shaft 9 and the fixed shafts 10, it is convenient for the operator to rotate the pull rod 13. When encountering partial handling, the angle of the pull rod 13 can be adjusted to reduce the labor intensity of the operator and improve the overall handling efficiency.

[0029] like Figure 3 As shown, the fixing block 12 is fixedly installed on the outer end face of the speaker housing 1. The fixing block 12 is provided with a first limiting rod 11 that limits the pull rod 13. The fixing block 12 is provided with a sliding groove. The moving plate 15 is slidably installed on the inner side wall of the sliding groove. The moving plate 15 and the first limiting rod 11 are fixedly connected. The inner side wall of the sliding groove is provided with a return spring 16. The end of the return spring 16 is fixedly installed on the inner side wall of the sliding groove by a hook. The other end of the return spring 16 is fixedly installed on the end of the moving plate 15 by a hook. This configuration provides the first limiting rod 11 with a return force.

[0030] It should be noted that the return spring 16 and the moving plate 15 cooperate with each other to compress the moving plate 15, ensuring that the first limiting rod 11 extends into the pull rod 13 to play a limiting role, preventing the first limiting rod 11 from falling off due to accidental circumstances, which would affect the subsequent fixing effect of the pull rod 13.

[0031] like Figure 6 As shown, the telescopic connecting rod 19 is fixedly installed at the bottom of the speaker housing 1, and the second limiting rod 20 is inserted into the outer wall of the telescopic connecting rod 19. The end of the telescopic connecting rod 19 is provided with a positioning hole 21, which is compatible with the positioning pin 18. Through the cooperation of the telescopic connecting rod 19 and the second limiting rod 20, it is convenient for operators to connect adjacent speaker housings 1. By inserting the second limiting rod 20, it is prevented that the telescopic connecting rod 19 may suddenly retract due to unexpected circumstances during the handling and connection, which would affect the efficiency of subsequent handling and increase the handling time.

[0032] The connecting shaft platform 17 is fixedly installed at the bottom of the speaker housing 1. A positioning pin 18 is inserted into the bottom of the connecting shaft platform 17, and the diameter of the positioning pin 18 is smaller than the diameter of the positioning hole 21. Through the cooperation of the positioning pin 18 and the telescopic connecting rod 19, the telescopic connecting rod 19 is fixed and limited, which makes it convenient for operators to connect multiple speaker housings 1 for transportation and improves the work efficiency of transporting multiple speaker housings 1.

[0033] The connecting shaft platform 17 has a rotating groove, which is fan-shaped. Through the cooperation of the rotating groove and the telescopic connecting rod 19, when transporting multiple speaker housings 1, when facing a curved road surface, the telescopic connecting rod 19 rotates in the rotating groove, which makes it convenient for the operator to adjust the angle when transporting multiple speaker housings 1.

[0034] The functional principle of this utility model can be explained through the following operation methods:

[0035] When it is necessary to move the speaker housing 1, the operator moves the first limiting rod 11, which drives the moving plate 15 to move. The moving plate 15 presses the return spring 16, and the first limiting rod 11 releases its limiting effect on the pull rod 13. The pull rod 13 rotates in the fixed shaft platform 10 through the second rotating shaft 9. Pulling the pull rod 13 drives the speaker housing 1 to move through the universal wheel 8, which facilitates the operator to move the speaker housing 1.

[0036] When the position of the speaker housing 1 needs to be adjusted, the two fixed rods 7 are pushed, and the fixed rods 7 drive the speaker housing 1 to move through the casters 8. When the speaker housing 1 needs to be lifted, the four handles 4 set on the upper and lower sides are used. The operator can rotate the handles 4 through the first rotating shaft 3 to save the operator's handling time and reduce the operator's labor intensity when lifting.

[0037] When multiple speaker housings 1 need to be moved, the telescopic connecting rod 19 is moved so that the end of the telescopic connecting rod 19 extends into the bottom of the adjacent speaker housing 1. The end of the telescopic connecting rod 19 is connected to the inner side wall of the rotating groove in the connecting shaft platform 17. The operator inserts the second limiting rod 20 to limit the telescopic connecting rod 19. The operator inserts the positioning pin 18, which passes through the positioning hole 21 to limit the end of the telescopic connecting rod 19, making it convenient for the operator to move multiple speaker housings 1.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
