Description

Technical Field

[0001] This utility model relates to the technical field of air-filled equipment accessories, and in particular to a novel air tube. Background Technology

[0002] An air pump extension tube is an additional flexible tube used to connect an air pump to an inflatable target (such as a tire, inflatable bed, swimming ring, etc.). Its main function is to extend the original length of the air pump, allowing it to more flexibly reach inflation ports that are difficult to access directly.

[0003] However, when unlocking the air hose extension tube and air hose connecting the air pump on the market under high temperature and pressure, the air hose screw is prone to slipping on the air hose body and is difficult to remove.

[0004] Therefore, improvements are needed. Utility Model Content

[0005] The technical problem solved by this utility model is to address the deficiencies in the prior art by providing a novel trachea to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a novel trachea, comprising: a trachea body, the trachea body having a hollow structure; a trachea screw, the trachea screw being embedded in the second end of the trachea body, the trachea screw having a hexagonal fixing part on its circumferential surface, the fixing part abutting against the opening of the trachea body; and a locking sleeve, the locking sleeve being fitted onto the outer circumferential surface of the second end of the trachea body, the locking sleeve having a groove on its end face that is adapted to the fixing part.

[0007] Furthermore, the outer peripheral surface of the lock sleeve is provided with serrated patterns to increase friction.

[0008] Furthermore, when the fixing part is embedded in the slot, the end face of the fixing part and the end face of the locking sleeve are at the same level.

[0009] Furthermore, the first end of the tracheal screw is provided with conical teeth on its circumferential surface, and the conical teeth are embedded in the second end of the tracheal body, and the conical teeth engage with the inner wall of the tracheal body.

[0010] Furthermore, the second end of the air pipe screw has an external thread structure on its circumferential surface for connecting to an external inflation device.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Anti-slip locking structure: The embedded engagement of the hexagonal fixing part and the locking sleeve groove solves the problem of traditional air hose screws slipping under high pressure. The fixing part abuts against the air hose body to form a double fixation, maintaining a stable connection even in high temperature and high pressure environments. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Moreover, "above," "over," and "on top" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] In view of the technical problems described in the background art, such as Figure 1-6 As shown, a novel trachea is provided, comprising: a trachea body, the trachea body having a hollow structure; a trachea screw, the trachea screw being embedded in the second end of the trachea body, the trachea screw having a hexagonal fixing part on its circumferential surface, the fixing part abutting against the opening of the trachea body; and a locking sleeve, the locking sleeve being fitted onto the outer circumferential surface of the second end of the trachea body, the locking sleeve having a groove on its end face that is adapted to the fixing part.

[0023] In the above, a novel air tube is configured to connect an air pump and a component to be inflated. The air tube body is a hollow flexible tube structure for gas transmission.

[0024] The other end of the air hose body is connected to an air hose screw and a locking sleeve. The air hose screw is in close contact with the inner wall of the air hose body. The second end of the air hose screw has an external thread structure on its circumferential surface for connecting to external inflation equipment. The air hose screw can be threadedly connected to an air pump or air compressor through the external thread structure. The outer circumferential surface of the air hose screw has a hexagonal fixing part, and the end face of the locking sleeve has a matching groove. When the air hose screw and the air hose body are assembled, the fixing part on the air hose screw and the groove on the locking sleeve engage. With this structure, when the air hose body is removed from the air pump or air compressor, the locking sleeve and the valve screw will not rotate relative to each other during the rotation of the locking sleeve, making it easy to unlock.

[0025] The embedded engagement of the hexagonal fixing part and the locking sleeve groove solves the problem of traditional air hose screws slipping under high pressure. The fixing part abuts against the air hose body to form a double fixation, maintaining a stable connection even in high temperature and high pressure environments.

[0026] As a feasible technical solution, the outer circumferential surface of the lock sleeve is provided with serrated patterns to increase friction. This increases the frictional force during manual tightening or loosening, facilitating operation.

[0027] Preferably, when the fixing part is embedded in the slot, the end face of the fixing part and the end face of the locking sleeve are at the same level.

[0028] like Figure 6 As shown, the first end of the endotracheal screw has tapered teeth on its circumferential surface, which are embedded in the second end of the endotracheal body and engage with the inner wall of the endotracheal body. The second end of the endotracheal screw has an external thread structure on its circumferential surface for connecting to an external inflation device.

[0029] The specific usage process is as follows: Press the tapered teeth of the trachea screw into the second end of the trachea body, so that its fixing part abuts against the end of the tube. Put the locking sleeve on the trachea body, rotate the locking sleeve to align the slot with the fixing part and lock it in place. Connect the trachea to the inflation device through the external thread structure to complete the assembly.

[0030] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
