Description

Technical Field

[0001] This utility model relates to the field of air pump hose connection technology, specifically an air pump hose rotary connection mechanism. Background Technology

[0002] When the air hose of an existing air pump is connected to the air outlet, it can only be fixed and cannot be rotated, making it inconvenient to store. Furthermore, when the air hose is not in use, it is easily lost if stored separately from the air pump. To solve these problems, this utility model provides a rotating connection mechanism for the air hose of an air pump. Utility Model Content

[0003] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a rotating connection mechanism for an air pump hose. An air nozzle sleeve is fitted over the outside of the rotating air nozzle, and the air nozzle sleeve is connected to the air hose via a tower-shaped head. Simultaneously, an air hole is opened on the side of the rotating air nozzle to connect to the tower-shaped head. This ensures that when the rotating air nozzle is installed on the air pump, the air hose can rotate around the air nozzle sleeve to adapt to different storage spaces, eliminating the need for separate storage of the air hose and facilitating its storage. This solves the technical problems raised in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a rotary connection mechanism for an air pump hose, comprising: a cylindrical rotary nozzle, a straight tubular nozzle sleeve, and an air hose; the nozzle sleeve is fitted on the outside of the rotary nozzle, the open end of the rotary nozzle is threadedly connected to the air outlet end of the air pump, a tubular tower-shaped head is integrally connected to the side of the nozzle sleeve, the tower-shaped head is connected to one end of the air hose, and air holes penetrating both sides are opened on the side of the rotary nozzle, the air holes passing through the axis of the rotary nozzle, the position of the air holes corresponding to the position of the inner diameter of the tower-shaped head; the air holes are perpendicular to the axis of the rotary nozzle, so as to ensure that when the nozzle sleeve and the air hose rotate around the rotary nozzle, the gas in the rotary nozzle can smoothly enter the air hose through the air holes.

[0005] Preferably, the outer limiting tube is integrally connected to the side of the air nozzle sheath. The outer limiting tube is located outside the tower-shaped head and coaxial. The end of the air pipe is installed between the outer limiting tube and the tower-shaped head. By setting the tower-shaped head and the outer limiting tube, a tight connection between the air pipe and the air nozzle sheath is achieved.

[0006] Preferably, the outer surface of the rotary nozzle has coaxially formed parallel annular sealing grooves A and B, which are located on both sides of the air hole. A sealing ring A is installed in the annular sealing groove A, and a sealing ring B is installed in the annular sealing groove B. By creating annular sealing grooves A and B on the outer surface of the rotary nozzle on both sides of the air hole, and simultaneously installing sealing rings A and B, the gas flowing through the air hole is sealed, resulting in good airtightness and convenient practicality.

[0007] Preferably, the sealing end of the rotary nozzle is coaxially and integrally connected to the sealing disc, and an annular groove is coaxially formed on the inner side of the end of the nozzle sheath, with the sealing disc installed in the annular groove to further improve the sealing performance.

[0008] Preferably, the other end of the air tube is connected to an air nozzle so as to connect to other components to be inflated.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] like Figures 1 to 4 As shown, this embodiment provides a rotary connection mechanism for an air pump hose, including: a cylindrical rotary nozzle 1, a straight tubular nozzle sleeve 2, and an air hose 3. The nozzle sleeve 2 is fitted over the outside of the rotary nozzle 1, and the open end of the rotary nozzle 1 is threadedly connected to the air outlet end of the air pump. A tubular tower-shaped head 21 is integrally connected to the side of the nozzle sleeve 2, and the tower-shaped head 21 is connected to one end of the air hose 3. Specifically, an outer limiting tube 22 is integrally connected to the side of the nozzle sleeve 2. The outer limiting tube 22 is located outside the tower-shaped head 21 and coaxial. The end of the air hose 3 is installed between the outer limiting tube 22 and the tower-shaped head 21. By setting the tower-shaped head 21 and the outer limiting tube 22, a tight connection between the air hose 3 and the nozzle sleeve 2 is achieved. More specifically, the other end of the air hose 3 is connected to a nozzle 5 for connecting other components to be inflated.

[0022] Please see Figure 4 As shown, the rotating nozzle 1 has air holes 11 that pass through both sides and pass through the axis of the rotating nozzle 1. The air holes 11 are perpendicular to the axis of the rotating nozzle 1 to ensure that when the nozzle sleeve 2 and the air pipe 3 rotate around the rotating nozzle 1, the gas in the rotating nozzle 1 can smoothly enter the air pipe 3 through the air holes 11. The position of the air holes 11 corresponds to the position of the inner diameter of the tower head 21.

[0023] Please see Figure 4As shown, the outer surface of the rotary nozzle 1 has coaxially parallel annular sealing grooves A12 and B13, located on both sides of the air hole 11. A sealing ring A41 is interference-fitted into an annular sealing groove A12, and a sealing ring B42 is interference-fitted into an annular sealing groove B13. By creating annular sealing grooves A12 and B13 on the outer surface of the rotary nozzle 1 on both sides of the air hole 11, and simultaneously installing sealing rings A41 and B42, a seal is achieved for the gas flowing through the air hole 11, resulting in good airtightness and convenient practicality. More specifically, a sealing disc 14 is coaxially and integrally connected to the sealing end of the rotary nozzle 1. An annular groove 23 is coaxially formed on the inner side of the end of the nozzle sleeve 2, and the sealing disc 14 is installed within the annular groove 23. By setting the sealing disc 14 to be fitted within the annular groove 23, the sealing performance is further improved.

[0024] In practical use, the nozzle sleeve 2 is fitted over the outside of the rotating nozzle 1, and the nozzle sleeve 2 is connected to the air pipe 3 through the tower-shaped head 21. Simultaneously, an air hole 11 is opened on the side of the rotating nozzle 1, connecting to the tower-shaped head 21. This ensures that when the rotating nozzle 1 is installed on the air pump, the air pipe 3 can rotate around the nozzle sleeve 2 to adapt to different storage spaces, eliminating the need for separate storage of the air pipe 3 and facilitating its storage. Furthermore, by opening annular sealing grooves A12 and B13 on the outside of the rotating nozzle 1 on both sides of the air hole 11, and correspondingly installing sealing rings A41 and B42, the gas flowing through the air hole 11 is sealed, resulting in good airtightness and convenient practicality.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
