Abstract
The utility model relates to a water seal, including the skeleton, the outside cladding combination of skeleton has sealing rubber, the last sealing edge that is equipped with of sealing rubber, and the skeleton is established to the shape of falling L, and sealing rubber's right side is equipped with two at least sealing edge, and sealing edge's root is equipped with the violently form muscle of two at least interval arrangements. It provides good sealed effect to little in the lip temperature rise of when operation dehydration, provide stable elasticity strength, make the lip the high -speed in operation of axle can have sufficient follow an ability and reduce the axle reverse lip deformability, effective influence that reduces vibrations to the lip.
Description
Technical field
The utility model belongs to technical field of sealing technology, relates to a kind of water seal.
Background technique
At present, water seal is set to the structure of band spring more, the water seal of this structure utilizes rubber and spring contraction strength to make water seal lip lock ring on axle, it can provide comparatively good sealing effect, but because not having water to cover in washing machine when there is washing machine drainage in it, when washing machine runs up and dewaters, the problem that the temperature rise of lip portion easily causes ageing of rubber to lose efficacy, for this reason, need a kind of water seal of new structure, solve the problems referred to above existing in prior art, it is made to provide good sealing effect, and lip temperature rise is little when dewatering running, stable elasticity strength is provided, make lip that enough following axis capability and reduce axle can be had in axle runs up to reverse lip deformability, the impact of effective reduction vibrations on lip.
Model utility content
The purpose of this utility model is, a kind of water seal is provided, because not having water to cover in washing machine when solving washing machine drainage existing in prior art, when washing machine runs up and dewaters, the problem that the temperature rise of lip portion easily causes ageing of rubber to lose efficacy, it is made to provide good sealing effect, and lip temperature rise is little when dewatering running, stable elasticity strength is provided, make lip that enough following axis capability and reduce axle can be had in axle runs up to reverse lip deformability, effectively reduce the impact of vibrations on lip.
For achieving the above object, the utility model provides a kind of water seal, comprise skeleton, the outside coated combination of skeleton has caulking gum, caulking gum is provided with seal lip, skeleton is set to inverted L-shaped, and the right side of caulking gum is provided with at least two seal lips, and the root of seal lip is provided with at least two spaced horizontal shape muscle.
In above scheme preferably, the root of the inner side of the seal lip on top is provided with three spaced horizontal shape muscle.
Can also preferably, the root of the inner side of the seal lip of bottom is provided with three spaced horizontal shape muscle.
Can also preferably, the quantity of seal lip is three.
Can also preferably, the seal lip on top be directed upwardly setting.
Can also preferably, the direction of the seal lip of bottom is arranged down.
Can also preferably, the direction of middle seal lip is arranged down.
Water seal of the present utility model, because not having water to cover in washing machine when solving washing machine drainage existing in prior art, when washing machine runs up and dewaters, the problem that the temperature rise of lip portion easily causes ageing of rubber to lose efficacy, make it provide good sealing effect, and lip temperature rise is little when dewatering running, provides stable elasticity strength, make lip that enough following axis capability and reduce axle can be had in axle runs up to reverse lip deformability, effectively reduce the impact of vibrations on lip.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of water seal of the present utility model;
Fig. 2 is the structural representation of the water seal of prior art.
In figure, 1 is skeleton, and 2 is caulking gum, and 3 is sealing lip, and 4 is horizontal shape muscle.
Embodiment
In order to understand the utility model better, below in conjunction with specific embodiment, the utility model is explained in detail.But, obviously can carry out different modification and remodeling to the utility model and not exceed the wider spirit and scope of the utility model of appended claims.Therefore, following examples have exemplary and hard-core implication.
Embodiment:
A kind of water seal, comprise skeleton 1, the outside coated combination of skeleton 1 has caulking gum 2, caulking gum 2 is provided with seal lip 3, skeleton 1 is set to inverted L-shaped, and the right side of caulking gum 2 is provided with at least two seal lips 3, and the root of seal lip 3 is provided with at least two spaced horizontal shape muscle 4.
In the above-described embodiments, the root of the inner side of the seal lip 3 on top is provided with three spaced horizontal shape muscle 4.
In the above-described embodiments, the root of the inner side of the seal lip 3 of bottom is provided with three spaced horizontal shape muscle 4.
In the above-described embodiments, the quantity of seal lip 3 is three.
In the above-described embodiments, top seal lip 3 be directed upwardly setting.
In the above-described embodiments, the direction of the seal lip 3 of bottom is arranged down.
In the above-described embodiments, the direction of middle seal lip 3 is arranged down.
Water seal of the present utility model, the left side of its caulking gum 2 can arrange corrugated surface, and the upper side of its caulking gum 2 can arrange notch, and the downside of its caulking gum 2 also can arrange notch, the cross section of notch can be rectangle, and its seal lip 3 contacts with axle and fits.
Water seal of the present utility model, it adopts non-spring structure, and its seal lip (3) is set to the structure of Bao Erchang, mainly utilizes the pressure of water that seal lip (3) is close on axle, thus reach sealing effect during its sealing; And seal lip (3) mainly relies on rubber elasticity strength to be attached on axle when dewatering, during high speed dewatering, enclasping force is little and make temperature rise little; The root of its seal lip (3) adopts several horizontal shape muscle (4) to be spaced, it keeps lip strength to be unlikely to entirely to be attached on axle and to rub when high water level, it provides stable elasticity strength when anhydrous, makes seal lip (3) be attached on axle; The structure at horizontal several intervals of shape muscle (4) can make seal lip (3) that enough following axis capability and reduce axle can be had in axle runs up to reverse lip deformability, also effectively can reduce the impact of vibrations on seal lip (3).
