Detailed Description

The invention will be further described with reference to specific embodiments, the advantages and features of the invention will become more apparent as the description proceeds. These examples are merely illustrative and do not limit the scope of the invention in any way. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention, and that such changes and modifications are intended to be included within the scope of the invention.

Referring to fig. 1 to 4, the utility model relates to a retractable anti-theft combined cover, which comprises a rotary cover 1, a telescopic pipe 2 and an inner plug 4, wherein the middle part of the rotary cover 1 is recessed downwards to form a middle groove 5, the telescopic pipe 2 is positioned outside the middle groove 5, and the upper part 21 of the telescopic pipe 2 is in a bell mouth shape and is attached to the outer wall (upper part) of the middle groove 5; the section of the middle part of the extension tube 2 is in a polygon prism shape, and the outer wall (lower part) of the middle groove 5 forms a polygon prism-shaped matching surface matched with the extension tube (the polygon prism-shaped matching surface enables the rotating cover and the extension tube to be mutually nested and matched in a sliding way after being assembled); the section of the lower part 23 of the extension tube 2 is circular, and the inner plug 4 is arranged at the periphery of the extension tube 2 and is coaxial with the extension tube 2; the outer part of the extension tube 2 is provided with an extension tube external thread, and the inner plug 4 is in threaded fit with the extension tube 2; the inner plug 4 is fixed on the inner wall of the bottle opening through the leakage-proof ring, an inner plug external thread matched with the inner thread of the bottle opening is arranged on the inner plug, and the thread pitch of the inner plug external thread is longer than that of the telescopic pipe external thread, so that the telescopic pipe cannot be separated from the inner plug when the inner plug is stopped at the bottle opening in the subsequent process of rotating the rotary cover.

And a sealing ring is arranged between the inner plug 4 and the extension tube 2.

The rotary cover 1 is a metal cover or a plastic cover.

The telescopic pipe 2 rotates along the circumferential direction along with the rotating cover 1 by the polygonal matching surface; only in the vertical direction, the telescopic pipe slides up and down on the inner wall of the rotating cover, namely the telescopic pipe can only slide up and down; in the circumferential direction of the telescopic pipe, the telescopic pipe rotates along with the rotating cover, and the telescopic pipe cannot rotate in the circumferential direction alone due to the arrangement of polygonal matching surfaces.

The rotary cover 1 is an aluminum bottle cover.

The utility model discloses a theory of operation (opening method), including following step:

(1) the rotating cover on the bottle body is rotated, the rotating cover moves upwards to be far away from the bottle body, and the matching surface of the rotating cover and the telescopic pipe is a polygonal matching surface, so that the rotating cover drives the telescopic pipe to rotate along the circumferential direction of the rotating cover;

(2) when the rotary cover moves upwards, the telescopic pipe and the inner plug rotate relatively at the same time and move upwards along with the rotary cover;

(3) when the rotary cover and the extension tube move upwards to a preset distance, the rotary cover is completely separated from the bottle opening, the rotary cover is taken down from the bottle opening, and the extension tube is left on the bottle opening while the rotary cover is taken down;

(4) the sealing ring at the bottom end of the telescopic pipe is clamped on the inner plug internal thread of the inner plug, the telescopic pipe is fixed under the dual fixing action of the inner plug internal thread and the sealing ring, and the telescopic pipe is in an extending state.

Based on the above principle, the utility model discloses a flexible pipe is automatic to be extended when rotatory lid is turned round to open, can guarantee that liquid is difficult to spill when empting, has guaranteed convenience and the reliability of using, simultaneously, because the utility model discloses when rotatory lid is turned round to open, flexible pipe is automatic to be extended, can not increase the volume of whole rotatory lid when extending flexible pipe for it is whole compacter pleasing to the eye more.
