Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.
The invention discloses a plugging head, which is shown in a figure 1 to a figure 3 and comprises: a knob 1, a positioning sleeve 2 and a positioning ball 3, wherein,
the positioning sleeve 2 is provided with a hollow space, and the knob 1 is hermetically sleeved in the hollow space and is in threaded fit with the positioning sleeve 2; the direction that the knob 1 extends into the hollow space is a first direction, the top end of the knob 1 is a cone section 14, and the diameter of the cone section 14 is gradually reduced in the first direction; the positioning sleeve 2 is provided with at least one radial through hole 21 which penetrates into the hollow space, the positioning ball 3 is arranged at the through hole 21, and after the knob 1 extends into the hollow space, the outer wall of the cone section 14 abuts against the positioning ball 3; a sealing gasket is arranged outside the positioning sleeve 2.
In use, the locating sleeve 2 extends into an open mouth, which can be any mouth that needs to be sealed. By screwing the knob 1, the positioning ball 3 is driven by the outer wall of the vertebral body section 14 to move outwards the through hole 21 and extend out of the through hole 21 to be fixed on the inner wall of the opening. Generally, in the preferred embodiment, the diameter of the through hole 21 is slightly smaller than the diameter of the positioning ball 3, so that the positioning ball 3 can be partially exposed and clamped in the opening.
The knob 1 is divided into in the first direction: a rotating section 11, a connecting section 12, a channel section 13 and a cone section 14; the connecting section 12 is cylindrical and is provided with an external thread at least on part of the outer wall, and is in threaded connection with the positioning sleeve 2, and the hollow space of the positioning sleeve 2 is correspondingly provided with an internal thread 22; the groove section 13 is provided with at least one circle of annular grooves for installing a sealing ring so as to ensure the sealing connection of the knob 1 and the positioning sleeve 2; the outer surface of the rotating section 11 is rough, so that the friction force during rotation is improved, and the manual operation is facilitated
The positioning sleeve 2 is in a stepped shaft shape and sequentially comprises a first shaft section with a larger diameter and a second shaft section with a smaller diameter in the first direction, and the through hole 21 is formed in the second shaft section. An annular groove 23 is formed at the junction of the first shaft section and the second shaft section for mounting a seal. The shape of the seal and the stepped shaft ensures the sealing between the positioning sleeve 2 and the opening.
The periphery wall of position sleeve 2 is the polished surface, conveniently inserts the opening. The tail part of the positioning sleeve 2 is provided with a boss 24 which can be propped against the outer end of the opening. The boss 24 faces one side of the first direction to form an annular clamping groove 25, and on some open-end mechanisms, the clamping groove 25 can be clamped on the outer wall of the open end. So as to improve the firmness of fixation.
The construction, features and functions of the present invention are described in detail in the embodiments illustrated in the drawings, which are only preferred embodiments of the present invention, but the present invention is not limited by the drawings, and all equivalent embodiments modified or changed according to the idea of the present invention should fall within the protection scope of the present invention without departing from the spirit of the present invention covered by the description and the drawings.
