Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that, in case of conflict, the embodiments of the present invention and features of the embodiments may be combined with each other.

The following describes a high-sealing double-layer vacuum cup provided by some embodiments of the present invention with reference to the accompanying drawings.

With reference to fig. 1-3, the utility model provides a double-deck thermos cup of high leakproofness, include: insulating cup 100, sealed bowl cover 200 and sealed lid 300 of drawing, insulating cup 100's top is equipped with screw lid mouth 110 and the inboard of sealed bowl cover 200 is equipped with the screw thread groove that connects with sealed bowl cover 200 looks adaptation, the pull straight hole 210 has been seted up on the surface of sealed bowl cover 200, the inside fixed mounting of pull straight hole 210 has the inflation strip to lead 220, the inboard of sealed lid 300 of drawing is seted up and is run through to the slide guide slot 301 of sealed lid 300 bottom surface of drawing, sealed lid 300 slides and cup joints in the inboard of pull straight hole 210, and the inflation strip is led 220 and is cup jointed in the inboard of slide guide slot 301, the top surface fixed mounting of sealed lid 300 of drawing has the lug 310, the bottom surface fixed mounting of sealed lid 300 of drawing has the inflation that supports lamella 320 with the inboard looks butt of screw lid mouth 110.

In this embodiment, the heat-insulating cup 100 and the sealing cup cover 200 are stainless steel members, and the top surface of the inner cavity of the sealing cup cover 200 is provided with a sealing press ring which is abutted with the top surface of the threaded cover opening 110.

Further, the bottom surface of the sealing pressure ring is of a plane structure, and the bottom surface of the sealing pressure ring and the top surface of the threaded cap opening 110 are of smooth surface structures.

Specifically, the mutual butt between the sealing press ring and the plane structure of the threaded cover opening 110 is utilized to avoid the friction transmission of the sealing press ring during the thread rotation motion of the sealing cup cover 200 and the threaded cover opening 110, and the effect of fitting sealing is achieved through the smooth surface contact of the sealing press ring and the threaded cover opening.

In this embodiment, the cross section of the expansion bar guide 220 is an isosceles triangle structure, the wedge guide slot 301 is an isosceles triangle, and the included angle of the wedge guide slot 301 is smaller than the size of the vertex angle of the expansion bar guide 220.

Specifically, by abutting the surfaces of the expansion strip guide 220 and the wedge guide groove 301, and by the difference of the surface deflection angles of the two, the expansion strip guide 220 performs the expansion movement of the expansion abutting flap 320 when moving relative to the wedge guide groove 301, so that the outer side of the expansion abutting flap 320 abuts against the inner wall of the threaded cover opening 110 for sealing, and the sealing effect is improved.

In this embodiment, the number of the expansion supporting flaps 320 is two, the two expansion supporting flaps are symmetrically distributed on two sides of the wedge guide slot 301 and fixed at the bottom end of the sealing pull cap 300, a sealing expansion strip 322 is arranged between the two expansion supporting flaps 320, and the same outer sealing ring 321 is sleeved on the outer peripheries of the two expansion supporting flaps 320.

Specifically, the sealing expansion strip 322 connected to the middle of the expansion supporting flap 320 ensures that the sealing between the expansion supporting flaps 320 prevents water from escaping through the space between the two expansion supporting flaps 320 during the expansion movement of the expansion supporting flaps 320, and the sealing expansion strip 322 sleeved outside the expansion supporting flaps 320 abuts against the inner wall of the threaded cover 110 after the expansion supporting flaps 320 expand to form a sealing effect.

In this embodiment, a tapered wedge guide groove 301 is provided on the outer side of the sealing pulling cap 300, and the tapered wedge guide groove 301 has an inclined arc surface.

Specifically, during the pressing motion of the sealing pull cover 300, the periphery of the sealing pull cover 300 expands during the relative motion of the wedge guide groove 301 and the expansion strip guide 220, so that the wedge guide groove 301 is abutted against the inner side of the straight drawing hole 210, and the friction force between the sealing pull cover 300 and the straight drawing hole 210 is improved to prevent the sealing pull cover 300 from freely moving.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
