Abstract
A teacup sealed with double conical surfaces comprises a cup cover (1), a cup wall (2) and a sealing gasket (3). The cup cover (1) is provided with internal threads. External threads are arranged on the upper portion of the cup wall (2). The teacup sealed with the double conical surfaces is characterized in that a big-end-up inner conical surface (5) and a big-end-down outer conical surface are arranged on the upper portion of the cup wall (2). The sealing gasket (3) is arranged inside the cup cover (1), and provided with an annular sealing groove which is provided with a small conical surface (7) and a big conical surface (6). The small conical surface (7) and the inner conical surface (5) are contacted and equal in conical degree. The big conical surface (6) and the outer conical surface (4) are contacted and equal in conical degree. The sealing gasket (3) is made of polytetrafluoroethene. The cup cover and the cup wall are sealed with double conical surfaces, so that sealing area is big, and sealing effect is good. Due to the fact that the sealing gasket is made of polytetrafluoroethene, service life is long.
Description
Technical field
The utility model relates to a kind of teacup, is specifically related to a kind of teacup with the Double-conical-surface sealing.
Background technology
People travel or have a meeting in the urban district, attend a lecture or attend a party, and often carry teacup.If the sealing effectiveness of teacup is bad, the tea in teacup or beverage will flow out, wetting clothing.Sealing between the bowl cover of existing teacup and the wall of cup of cup is often by sealing gasket.Because the wall of cup of cup is thinner, so the pressure that sealing gasket bears is very large, is easy to when the user tightens bowl cover sealing gasket is damaged by pressure; Perhaps service time slightly long, sealing gasket follows the string and no longer seals.Sealing gasket had damaged originally and can change, but because the model of teacup on market is various, cause the model of sealing gasket various, and the profit of selling sealing gasket is too little, therefore businessman is unwilling to sell sealing gasket, and the consumer also can't solve the sealing problem of teacup with regard to being difficult to have bought suitable sealing gasket.
The utility model content
The technical problems to be solved in the utility model is to overcome the shortcoming that the sealing gasket between the wall of cup of the bowl cover of existing teacup and cup easily can't seal because of damage, a kind of teacup with the Double-conical-surface sealing is provided, and the good sealing effect of this teacup, sealing-plug are not easy to damage.
The technical solution adopted in the utility model is: described a kind of teacup with the Double-conical-surface sealing, comprise bowl cover, wall of cup and sealing gasket, described bowl cover has internal thread, the top of described wall of cup has external screw thread, it is characterized in that: the top of described wall of cup has up big and down small internal conical surface and up-small and down-big outer conical surface; Sealing gasket is installed in described bowl cover, described sealing gasket has annular seal groove, described annular seal groove has a roundlet conical surface and a large taper seat, and the described roundlet conical surface contacts with described internal conical surface and tapering equates, described large taper seat contacts with described outer conical surface and tapering equates.
As the improvement to above technical scheme, described sealing gasket is made with polytetrafluoroethylene (PTFE).
Beneficial effect: bowl cover and wall of cup are with the sealing of double cone face, and sealing area is large, good sealing effect; Sealing gasket adopts polytetrafluoroethylene (PTFE) to make, long service life.
Description of drawings
Fig. 1 is the front view with the teacup of Double-conical-surface sealing;
Fig. 2 is A place enlarged drawing in Fig. 1;
Fig. 3 is the enlarged drawing of the sealing gasket in Fig. 1.
In figure: 1, bowl cover; 2, wall of cup; 3, sealing gasket; 4, outer conical surface; 5, internal conical surface; 6, large taper seat; 7, the roundlet conical surface.
The specific embodiment
Below in conjunction with Fig. 1 to Fig. 3, the utility model is described in further detail: a kind of teacup with the Double-conical-surface sealing, comprise bowl cover 1, wall of cup 2 and sealing gasket 3, described bowl cover 1 has internal thread, the top of described wall of cup 2 has external screw thread, it is characterized in that: the top of described wall of cup 2 has up big and down small internal conical surface 5 and up-small and down-big outer conical surface 4; The interior installation sealing gasket 3 of described bowl cover 1, described sealing gasket 3 has annular seal groove, described annular seal groove has a roundlet conical surface 7 and a large taper seat 6, the described roundlet conical surface 7 contacts with described internal conical surface 5 and tapering equates, described large taper seat 6 contacts with described outer conical surface 4 and tapering equates.
As the improvement to above technical scheme, described sealing gasket 3 use polytetrafluoroethylene (PTFE) are made.
Sealing gasket 3 sticks with glue at the inner surface of the top board of bowl cover 1.
Claims (2)
