Description

Vacuum cup convenient to open and close

Technical Field

The utility model belongs to the technical field of vacuum cups, and particularly relates to a vacuum cup convenient to open and close.

Background

The vacuum cup is a container made of ceramic or stainless steel and vacuum layer, the top of the container is covered tightly, the vacuum heat insulating layer can delay the heat dissipation of the liquid such as water in the container, so as to achieve the purpose of heat preservation. The thread connection tightness of the heat preservation cup cover and the cup body is the key of the heat preservation effect. The design of the heat preservation cup cover in the market at present is various, but most of the heat preservation cup covers can be opened again after the pressure in the cup and the atmospheric pressure are balanced before the cover is opened. In the in-service use process, it is very hard also to open after the thermos cup exhausts often to appear, the reason is: in the process of screwing the cup cover, the cup cover is rotated to enable the threads to rotate, the sealing washer between the cup opening and the cover is extruded and deformed due to the pressure of the winding body in the process, extrusion stress can be generated between the cup opening and the cover, and the cup cover can be opened only by overcoming great friction force if the cup cover needs to be opened. The closer the screw joint is, the more favorable the heat preservation effect is, but the closer the screw joint is, the more difficult the cover is to be opened, and the sealing performance and the convenience for opening the cover are in a mutual contradictory relationship.

Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples serve to illustrate the utility model.

As shown in the attached drawings 1 to 3, the cup comprises a cup body 1 and a cover body 2, wherein the lower portion of the cup body 1 is used for containing liquid, a cup opening is formed in the top of the cup body 1, internal threads are formed in the upper portion of the inner wall of the cup opening, a sealing area 3 is formed in the lower portion of the cup opening, the longitudinal section of the sealing area 3 is in a trapezoid shape with the large top and the small bottom, the bottom of the cover body 2 is in an inverted trapezoid shape, the bottom of the cover body 2 is matched with the sealing area 3, the upper portion and the lower portion of the cover body 2 are respectively a fastening portion 4 and a sealing portion 5, a sealing ring 6 is sleeved at the bottom of the sealing portion 5, the sealing ring 6 is in interference fit with the sealing area 3, a convenient opening assembly is arranged on the fastening portion 4, and the convenient opening assembly can be matched and connected with the internal threads of the cup opening. Set up like this, when lid 2 covers the rim of a cup, the sealing ring 6 of lid 2 bottom can seal the gap of rim of a cup sealing zone 3 and sealing 5, and convenient subassembly of opening can be together fixed lid 2 and rim of a cup, the operation of being convenient for.

In order to facilitate opening the lid 2, the upper portion setting of sealing 5 is the tubbiness, the top of sealing 5 is equipped with the internal thread, the upper portion of fastening 4 is equipped with the external screw thread, the lower part of fastening 4 stretches into in the sealing 5 and the spiro union, the center of the bottom of sealing 5 is equipped with exhaust hole 7, the center of the bottom of fastening 4 is equipped with sealed rubber pier 8, sealed rubber pier 8 can block up in the exhaust hole 7, just the outer diameter of sealed rubber pier 8 is than the internal diameter of exhaust hole 7 is slightly big, convenient subassembly setting of opening is in on the lateral wall of fastening 4 body. When the fastening part 4 is opened and loosened from the cup opening, a gap appears between the fastening part 4 and the sealing part 5, the sealing rubber pier 8 leaves the exhaust hole 7, the inside of the cup body 1 is communicated with the outside through the exhaust hole 7 and the gap between the fastening part 4 and the sealing part 5 of the cover body 2, and the air pressure in the cup body 1 is enabled to be balanced with the outside atmosphere through the exhaust hole 7. So that the cover body 2 can be conveniently unscrewed from the cup body 1.

Furthermore, the side wall of the sealing part 5 is provided with a positioning hole 13, the bottom of the fastening part 4 is provided with a baffle plate, an opening and closing groove 9 is arranged above the baffle plate, the opening and closing groove 9 is arranged along the circumferential direction of the fastening part 4, the cross section of the opening and closing groove is in a trapezoid shape with a large top and a small bottom, an external thread is arranged above the opening and closing groove 9, the convenient opening and closing assembly comprises a positioning bead 12, the positioning bead 12 can move up and down in the opening and closing groove 9, one side of the positioning bead 12 props against the opening and closing groove 9, the other side of the positioning bead 12 is limited in the positioning hole 13, the diameter of the positioning hole 13 is smaller than the outer diameter of the positioning bead 12, when the positioning bead 12 props against the top of the opening and closing groove 9, the other side of the positioning bead 12 can protrude outwards to the outside of the positioning hole 13 to be pressed with the thread of the internal thread area, when the positioning bead 12 props against the bottom of the opening and closing groove 9, the other side of the positioning bead 12 is positioned in the positioning hole 13; the sealing rubber pier 8 is arranged on the lower side of the baffle 10, and the baffle can block the positioning beads so that the positioning beads are positioned in the opening and closing grooves. Through the above arrangement, when the fastening part 4 is screwed into the sealing part 5, the positioning bead 12 slides to the top end from the bottom end of the opening and closing groove 9, the sealing rubber pier 8 blocks the exhaust hole 7, and meanwhile, the fastening part 4 extrudes one side of the positioning bead 12 out of the positioning hole 13. The outer hole of the positioning hole 13 is smaller than the diameter of the positioning steel ball, so that the positioning ball 12 cannot fall out of the positioning hole. The positioning ball 12 is screwed with the internal thread of the cup mouth to drive the cover body 2 to rotate downwards, the sealing ring 6 is tightly pressed on the trapezoidal inclined plane of the sealing area 3, the purpose of complete sealing is achieved, if the fastening part 4 is screwed continuously, meanwhile, the fastening part is tightly screwed with the sealing part, and the positioning ball 12 continuously moves outwards to be in a locking state with the internal thread of the cup mouth.

In order to ensure that the positioning bead 12 timely returns to the bottom of the opening and closing groove 9 in the process of opening the cover, a magnetic block 14 is arranged in the sealing part 5, the positioning bead 12 is made of hard magnetic materials, and the magnetic block 14 is positioned below the opening and closing groove 9.
