The washer electric heating pipe sealing structure formed by the sealing cushion not only has simple structure, but also has good sealing effect.
Description
Technical field
The utility model relates to a kind of sealing gasket, specifically a kind of sealing gasket that roller washing machine electrical heating tube and similar structure thereof are sealed that is applicable to.
Background technique
At present, the installation sealing gasket of existing roller washing machine electrical heating tube has two kinds of sealing configurations usually, and a kind of is structure as Fig. 4: wherein Fig. 4 A is the state of nut 2 when not tightening, and Fig. 4 B is the state of nut 2 when tightening; In the time of in this state, the water tank interface 5 of washing machine is made interior slope 51, during installation, tighten the nut 2 that is positioned on the connecting screw rod 1, utilize relatively moving of flange 3 and flange bracket 6, make the compressive deformation and the water tank interface 5 of sealing gasket 4 form back-off, thereby reach the purpose of fastening electrical heating tube 7, this structure cooperates the effect that therefore can reach sealing because sealing the time is the inclined-plane, but water tank interface 5 must be made interior slope 51, mould need be made inner core pulling when injection molded, to such an extent as to the cost height, the shaping difficulty is big.Another kind of is exactly structure as Fig. 5: wherein Fig. 5 A is the state of nut 2 when not tightening, and Fig. 5 B is the state of nut 2 when tightening; Under this state, the water tank interface 5 of washing machine can be made straight tube, reaches purpose fastening, the sealed electrical heating tube with the frictional force of water tank interface generation when utilizing sealing gasket 4 distortion during installation, and the manufacturing of this kind structure is simple, but owing to only rely on the frictional force sealing, so poor sealing performance.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of sealing gasket, and the washing machine electrical heating tube sealing configuration that uses this kind sealing gasket to be constituted is not only made simply, and sealing effect is very good.
A kind of sealing gasket provided by the utility model comprises the annular seal pad main body of being with mesopore, in a side of sealing gasket main body the annular seal section of diameter less than the sealing gasket main body is arranged, and in the annular seal section outside bulge loop is arranged, and bulge loop constitutes the taper inner cavity.
In the interior side direction mesopore of described taper inner cavity, be extended with step taper inner cavity.
Opposite side in described cylindrical seal pad main body has boss.
The utility model is owing to adopted the side in the sealing gasket main body that the annular seal section of diameter less than the sealing gasket main body arranged, in the annular seal section outside bulge loop is arranged, bulge loop constitutes the structure of taper inner cavity, like this, the washing machine electrical heating tube sealing configuration that uses this kind sealing gasket to be constituted is not only made simply, and sealing effect is very good.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See also Fig. 1 and Figure 1A, it is a kind of sealing gasket 4, comprises the cylindrical seal pad main body 41 of being with mesopore 44, in a side of sealing gasket main body 41 the cylindrical seal section 46 of diameter less than sealing gasket main body 41 is arranged, in cylindrical seal section 46 outsides bulge loop 42 is arranged, bulge loop 42 constitutes taper inner cavity 47; In the interior side direction mesopore 44 of described taper inner cavity 47, be extended with step taper inner cavity 45; Opposite side in described cylindrical seal pad main body 41 has boss 43.
See also Fig. 2, in embodiment illustrated in fig. 2, tighten the nut 2 that is positioned on the connecting screw rod 1, make flange 3 and flange bracket 6 compression seal pads 4, this moment, the inclined-plane 61 of flange bracket 6 expanded in the taper inner cavity 47 of sealing gasket 4, thereby the bulge loop 42 that makes sealing gasket 4 to around expand and in water tank, keep away the formation back-off, the screwing force of adjusting nut is controlled the decrement of sealing gasket and the size of back-off, thereby obtains bigger and the power of deviating from water tank interface 5.
In Fig. 3, electrical heating tube 7 is inwardly packed into from outer dress the water tank 9, fastening nut is fixed on the washing machine water tank 9 electrical heating tube 7 then, be generally and prevent to reveal the influence that causes personal safety because of the water in the water tank 9, this sealing configuration requires can bear certain hydraulic pressure and deviate from power, in the bottom of water tank 9 water intake 8 is arranged.
Above-mentioned enforcement is the example that is sealed into the roller washing machine electrical heating tube; but application of the present utility model includes but not limited to the application of roller washing machine electrical heating tube; every and the utility model structure are identical substantially or utilize the novel invention spirit of this reality; the small improvement of being done on the utility model all belongs to the scope that the utility model is protected.
