One end of the lower inner part has a through hole through which the retaining ring of the tubular joint passes, and the lower inner part is engaged within the lower outer part. Both ends of the tube body are inserted into their corresponding lower inner parts and engaged within them by retaining rings. This utility model has a simple structure, is easy to operate, and the tube body does not rotate during threaded connection.

Description

Technical Field

[0001] This utility model specifically relates to a self-rotating air tube. Background Technology

[0002] When inflating a tire, the air outlet needs to be connected to the air hose, and the most common connection method now is a threaded connection. However, the threaded connection requires rotating the air outlet, which in turn affects the equipment connected to the air outlet, making it relatively inconvenient to operate. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a self-rotating airway.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A self-rotating air tube includes a tube body and connectors at both ends of the tube body. The connectors are characterized in that: each connector includes an upper outer part, a lower outer part, an upper inner part, a lower inner part, and a tubular joint; one end of the tubular joint has an integrally formed connection port, and the outer surface of the other end of the tubular joint has a protruding retaining ring; one end of the upper inner part has an upper retaining end capable of movably connecting with the connection port, and the outer surface of the upper inner part has an integrally formed outer retaining pattern; the inner side of the upper outer part has an outer retaining groove capable of engaging with the outer retaining pattern; one end of the lower inner part has a through hole through which the end of the tubular joint with the retaining ring passes, and the lower inner part is engaged within the lower outer part; both ends of the tube body are respectively inserted into the corresponding lower inner parts and engaged within them by retaining rings.

[0006] Furthermore, the outer surface of the upper connector is provided with a wave pattern.

[0007] Compared with the prior art, this utility model has the following advantages and effects: simple structure, convenient operation, and the pipe body will not rotate together when making threaded connection. Attached Figure Description

Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Example

[0019] like Figures 1-8 As shown, this embodiment includes a tube body 1 and connectors disposed at both ends of the tube body 1. All connectors are used to connect to air ports. Each connector includes a tubular joint 2, an upper external connector 3, an upper inner connector 4 snapped into the upper external connector 3, a lower external connector 5, and a lower inner connector 6 snapped into the lower external connector 5.

[0020] like Figures 1-8 As shown, one end of the tubular connector 2 has an integrally formed connection port 7, and the outer surface of the other end of the tubular connector 2 has a protruding retaining ring 8. One end of the upper inner connector 4 has an upper retaining end through which the connection port 7 can pass, and the outer surface of the upper inner connector 4 has an integrally formed outer retaining pattern 9. The inner side of the upper outer connector 3 has an outer retaining groove 10 that can engage with the outer retaining pattern 9. One end of the lower inner connector 6 has a through hole 11 through which the end of the tubular connector with the retaining ring 8 can pass, and the lower inner connector 6 is engaged in the lower outer connector 5. Both ends of the tube body 1 are inserted into the corresponding lower inner connector 6 and engaged in the lower inner connector 6 by the retaining ring 8. The inner side of the upper inner connector 4 has a thread 12. Specifically, to connect this connector to the outside, only the upper outer connector needs to be rotated to achieve the thread 12 connection. When the upper outer connector drives the upper inner connector to rotate, the tube body 1 will not rotate together.

[0021] In this embodiment, the outer surface of the upper external connector 3 is provided with a wave pattern 13, which allows the operator to easily pinch the upper external connector 3.

[0022] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
