[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 5 This invention discloses a detachable aluminum tube and aluminum rod composite connection structure for a vacuum cleaner, comprising an aluminum tube body 1 and an aluminum rod body 2. One end of the aluminum tube body 1 is fixedly connected to the vacuum cleaner main unit 3, and one end of the aluminum rod body 2 is connected to the vacuum head 4. The other end of the aluminum rod body 2 is inserted into the bottom end of the aluminum tube body 1. An inner liner tube 5 is provided at the bottom end inside the aluminum tube body 1, forming an insertion groove 6 between the inner liner tube 5 and the inner sidewall of the aluminum tube body 1. An O-ring seal 7 is provided at the top end inside the insertion groove 6. The bottom of the inner wall of the aluminum tube body 1 is provided with several vertical grooves 8 and several limiting horizontal grooves 9 that communicate with the vertical grooves 8. The outer side of the aluminum tube body 1 is provided with positioning bolts 10 that connect to the aluminum rod body 2. The top of the inner side of the aluminum rod body 2 is provided with an insertion guide bushing 11. The insertion guide bushing 11 and the inner wall of the aluminum rod body 2 form an insertion groove 2 12. The bottom of the insertion groove 2 12 is provided with an O-ring seal 2 13. The top of the outer wall of the aluminum rod body 2 is fixedly provided with several limiting heads 14 that match the vertical grooves 8 and the limiting horizontal grooves 9.

[0023] During installation, the aluminum rod body 2 is inserted into the aluminum tube body 1, so that the limiting head 14 enters the vertical groove 8. Then, the aluminum tube body 1 and the aluminum rod body 2 are rotated in a staggered manner, so that the limiting head 14 enters the limiting horizontal groove 9, thereby achieving the limiting function. During the insertion process, the inner liner tube 5 is inserted into the insertion groove 2 12, and the insertion guide inner liner 11 is inserted into the insertion groove 1 6 to improve the stability of the connection. Finally, the positioning bolt 10 is used to lock and limit the connection. The O-ring 1 7 and the O-ring 2 13 can improve the sealing of the connection between the aluminum tube body 1 and the aluminum rod body 2.

[0024] The diameter of the limiting head 14 is the same as the width of the vertical groove 8 and the limiting horizontal groove 9, which can prevent the formation of gaps and cause the connection to become loose;

[0025] The cross-sectional diameter of O-ring 7 is the same as the width of the insertion groove 6, and the cross-sectional diameter of O-ring 13 is the same as the width of the insertion groove 12. This can prevent O-ring 7 and O-ring 13 from falling off during assembly.

[0026] The aluminum tube body 1 has a through hole 15 that matches the positioning bolt 10, and the aluminum rod body 2 has a threaded hole 16 that matches the through hole 15 and the positioning bolt 10, which can be connected with the positioning bolt 10 to form a limiting function.

[0027] A connecting ring 17 is fixedly provided on the outer side of the aluminum tube body 1. A connecting rope 18 connected to the positioning bolt 10 is provided on the connecting ring 17, which can prevent the positioning bolt 10 from being lost when it is disassembled.

[0028] The bottom of the outer side of the aluminum tube body 1 and the top of the outer side of the aluminum rod body 2 are both rounded, which can improve the safety during operation and prevent users from being cut.

[0029] In operation, the system incorporates an inner liner, a first insertion slot, a first O-ring seal, a vertical groove, a limiting horizontal groove, a positioning bolt, an insertion guide inner liner, a second insertion slot, a second O-ring seal, and a limiting head. This allows the aluminum tube body and the aluminum rod body to be inserted together, forming a insertion limit, improving connection stability and force uniformity, and enhancing the sealing performance. Through holes and threaded holes allow connection with the positioning bolt, achieving a limiting and reinforcing effect. Connecting rings and connecting ropes prevent the positioning bolt from being lost. The rounded corners at the bottom of the outer side of the aluminum tube body and the top of the outer side of the aluminum rod body prevent cuts to the user, improving safety.
