Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "open," "upper," "lower," "thickness," "top," "middle," "length," "inner," "peripheral," and the like indicate orientation or positional relationships, merely for convenience in describing the present utility model and to simplify the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-5, the present utility model is a hose docking structure, which includes a connection tube 2, wherein two ends of the connection tube 2 are respectively provided with a male tube 20, an external thread structure 22 is disposed on a peripheral sidewall of the male tube 20, an internal thread tube 3 is screwed on the male tube 20, an internal thread structure 31 screwed with the external thread structure 22 is disposed on an inner sidewall of one end of the internal thread tube 3, and a male ring 21 is disposed on an end of the connection tube 2.

When in use, the internal thread tube 3 is inserted into one end of the hose 1, and the hose 1 is controlled by adopting a first hose clamp 10 to be fixed on the internal thread tube 3; then the control hose 1 continues to move and passes through the convex ring 21 to be sleeved on the end part of the connecting pipe 2, and then the second hose clamp 11 is adopted to control the hose 1 to be fixed on the connecting pipe 2.

In the above, by rotating the connecting pipe 2 along the end of the internal thread pipe 3, the hose 1 is conveniently controlled to be screwed onto the connecting pipe 2, and by using the preset internal thread pipe 3, not only is the hose 1 convenient to operate and control, but also the alignment of the connecting pipe 2 and the internal thread pipe 3 is conveniently controlled, so that the installation of the connecting pipe 2 is convenient; meanwhile, the convex ring 21 is used for a certain stop, so that the firmness of fixing the hose 1 on the connecting pipe 2 is improved.

The cross section of the convex ring 21 is in a semicircular structure or other cambered surface structures.

Based on the above, in order to better control the connection pipe 2 to be matched with the hose 1, a guiding inclined plane 24 is arranged on the end face of the connection pipe 2, and the setting of the guiding inclined plane 24 is utilized to conveniently control the connection pipe 2 to be inserted into the hose 1 and avoid the damage to the hose 1 possibly caused by the edge angle of the end part of the connection pipe 2 in the rotation process.

It will be appreciated that the external diameter of the internally threaded tube 3 is smaller than the external diameter of the connecting tube 2, the external diameter of the collar 21 being slightly larger than the internal diameter of the hose 1; the inner diameter of the hose 1 is larger than the outer diameter of the connection pipe 2.

If the outer diameter of the collar 21 is 2.1cm when the inner diameter of the hose 1 is 2cm, the outer diameter of the internally threaded tube 3 is 1.7cm and the connecting tube 2 is 1.8cm.

Or when the inner diameter of the hose 1 is 2cm, and the outer diameter of the collar 21 is 2.15cm, the outer diameter of the internally threaded tube 3 is 1.7cm, and the connecting tube 2 is 1.8cm.

The collar 21 is located between the first and second cuffs 10 and 11 provided at the end of the same hose 1 when installed.
