Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 7, a telescopic rod structure includes a first pipe 10, a second pipe 20, a friction member 30, and a fixing member 40. In this embodiment, the first pipe 10 and the second pipe 20 are aluminum pipes, each having a circular cross section, and the pipe diameter of the first pipe 10 is smaller than that of the second pipe 20. The friction member 30 is cylindrical and made of engineering plastics, and is fixedly sleeved outside the bottom of the first pipe fitting 10, and a ring of protruding parts 31 are arranged in the middle of the outer vertical wall. The fixing member 40 is a cylindrical member having both ends opened, is made of engineering plastic, and is fixed to the inner side of the top of the second pipe member 20. During assembly, the first pipe fitting 10 with the friction piece 30 sleeved on the top is inserted into the second pipe fitting 20, and the protruding part 31 of the friction piece 30 is tightly matched with the inner wall of the second pipe fitting 20; the fixing member 40 is then fixed to the top inner side of the second pipe member 20, preventing the first pipe member 10 from being released from the second pipe member 20.

As shown in fig. 1, 2 and 4, the friction member 30 extends upwardly from the lower edge or downwardly from the upper edge with at least one slot 32. The slot 32 extends vertically from one end to the other, but does not extend vertically through the upright walls of the friction member 30. The inner wall of the friction piece 30 is provided with at least two first reverse buckles 33, and the first reverse buckles 33 are uniformly arranged along the radial direction; correspondingly, the vertical wall of the first pipe 10 is provided with small holes 11 corresponding to the number and positions of the first reverse buckles 33. The friction member 30 has a ring of protrusions 34 extending radially inward from the edge of the vertical wall at the lower end thereof. When the friction member 30 is sleeved on the bottom of the first pipe 10, the convex ring 34 covers the bottom of the first pipe 10, and each first reverse buckle 33 is embedded into the corresponding small hole 11. Therefore, the friction member 30 cannot slide up and down, left and right relative to the first pipe 10, and the friction member 30 is fixed with the first pipe 10.

As shown in fig. 1, 3 and 5, the fixing member 40 extends upward from a lower edge to form at least one slit 41, and the slit 41 extends vertically without penetrating through the vertical wall of the fixing member 40 in the vertical direction. The outer wall of the fixing piece 40 is provided with at least two second reverse buckles 42, and the second reverse buckles 42 are uniformly arranged along the radial direction; correspondingly, the inner wall of the second pipe 20 is provided with grooves 21 corresponding to the number and positions of the second reverse buckles 42. The upper end of the fixing member 40 has a ring of bosses 43 extending radially outward from the edge of the upright wall. When the fixing member 40 is sleeved on the top of the second pipe 20, the boss 43 covers the top of the second pipe 20, and each second inverted buckle 42 is embedded into the corresponding groove 21, so that the fixing member 40 cannot slide up and down, left and right relative to the second pipe 20, and the fixing member 40 is fixed with the second pipe 20.

As shown in fig. 6, after the telescopic rod structure is assembled, if the telescopic rod needs to be shortened, the first pipe 10 is pushed to slide downwards or the second pipe 20 is pushed to slide upwards, and after the friction member 30 slides along with the first pipe 10 to a required length, the friction member 30 is used for positioning the first pipe 10 and the second pipe 20 by virtue of the friction force of the friction member 30 relative to the second pipe 20. If the extension of the telescopic rod is required, as shown in fig. 7, the first pipe 10 is pushed to slide upwards or the second pipe 20 is pushed to slide downwards, and after the friction member 30 slides along with the first pipe 10 to a required length, the friction member 30 is used for positioning the first pipe 10 and the second pipe 20 by virtue of the friction force of the friction member 30 relative to the second pipe 20. In the state where the friction member 30 is next to the fixing member 40, the telescopic bar is longest, as shown in fig. 7.

As shown in fig. 8, a vertical electric hair dryer device comprises a blowing assembly 200, a base 300 and the telescopic rod structure 100, wherein the blowing assembly 200 is rotatably connected with the upper end of a first pipe 10 of the telescopic rod structure 100, the base 300 is connected with the lower end of a second pipe 20 of the telescopic rod structure 100, the blowing assembly 200 comprises a cylindrical shell 210, an air duct assembly and a heating assembly, the air duct assembly and the heating assembly are arranged in the shell 210, an air inlet 211 is arranged at one end of the shell, and an air outlet 212 is arranged at the lower side of the shell.
