Abstract
The utility model provides a cover of the drinking water barrel, targeting at overcomes the weakness of the bad sealing function of the present cover of the drinking water barrel, so that the cover has a satisfied sealing function. A convex inner wall is arranged in the inner wall of the barrel cover; the outer edge of the convex inner wall is essentially an inclined square root shape sealing band (1); a groove (5), which makes the fulcrum expending and contracting when the fulcrum is pressed, is arranged at the back end of a fulcrum of the sealing band (1). A stand ring (4) whose section is an arc is arranged on the barrel cover; which clamps the arc outer wall of the barrel neck with the sealing band from up and down. As the outer edge of the sealing band is in square root shape like a tree crotch, the upper and the lower fulcrums attach the barrel neck closely, with the effect of the tension of the water absorbed in the middle of the two fulcrums, the sealing band attaches to the bottle neck closely like a sucker, so the sealing function of the utility model is much better than of the single-contact waterproof line. Moreover, with the cooperation of the lower stand ring, the sealing function is much better.
Description
Technical field
The utility model relates to daily water breaker, especially the lid on the water breaker.
Background technology
Existing Drinking water pail cover is all taked seal approach, mainly is to adopt a seal ring to seal, and the sealing circle is commonly called as water-proof wire in the industry.But the inner edge cross section of the water-proof wire on the existing Drinking water pail cover only is a point, and it is that a point type contacts with water breaker neck wall, and inductility, and sealing effectiveness is not ideal enough.
Summary of the invention
The utility model is intended to the defective at the sealing effectiveness difference of existing water breaker bung existence, and a kind of new-type Drinking water pail cover is provided, and makes it reach the satisfactory sealing effect.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of Drinking water pail cover is characterized in that: the inwall of bung is provided with one and protrudes inwall, and its outer roughly is the sealing band of inclination " √ " font, and outer two fulcrums of sealing bar are close to the arc outer wall of barrel neck.
The degree of dip of the outer of described sealing band, be close to the bucket neck arc outer wall be complementary.
In the described sealing band fulcrum, the upper end fulcrum is shorter than lower sustainer, protrudes lower sustainer slightly.
Described sealing band fulcrum rear end is provided with the groove of dilatation when fulcrum is squeezed.
Outer two fulcrums of described sealing band are close to up section of the arc outer wall of barrel neck, and it is the backing ring of arc that a cross section is arranged on descending section cooresponding bung of this arc outer wall, cooperate the arc outer wall of clamping bucket neck up and down with sealing band.
The utility model is owing to adopt above structure to make it possess following advantage:
Because the outer of sealing band is that " √ " font is just as tree fork shape, two fulcrums are close to a barrel neck up and down, under the tension force effect of the adsorbed water in this two fulcrums middle part, sealing band is attached on barrel neck firmly as sucker, sealing function are better than the water-proof wire of single-point contact greatly.And under the mating reaction of bottom backing ring, make sealing effectiveness even more ideal.

The specific embodiment
The utility model proposes a kind of Drinking water pail cover, be intended to overcome the sealing effectiveness difference defective that existing water breaker bung exists, make it reach the satisfactory sealing effect.
The inwall of this bung is provided with one and protrudes inwall, and its outer roughly is slightly inwardly recessed sealing band 1 of inclination " √ " font, middle part.The sealing bar is close to for up section and is sealed and matched with the arc outer wall (being positioned at a barrel neck top) of bucket neck.In two fulcrums, upper end fulcrum 2 is shorter than lower sustainer 3, protrudes lower sustainer slightly about the described sealing band, under the tension force effect of the adsorbed water in this two fulcrums middle part, sealing band is attached on barrel neck firmly as sucker.The backing ring 4 that on descending section cooresponding bung of this arc outer wall a cross section to be arranged be arc cooperates the arc outer wall of clamping bucket neck up and down with sealing band 1.
In order to improve the elasticity of sealing band, and strengthen sealing effectiveness, be provided with in sealing band lower fulcrum rear end when fulcrum is squeezed can dilatation groove 5.
Claims (5)
1, a kind of Drinking water pail cover is characterized in that: the inwall of bung is provided with one and protrudes inwall, and its outer roughly is the sealing band (1) of inclination " √ " font, and outer two fulcrums (2,3) of sealing bar (1) are close to the arc outer wall of barrel neck.
2, a kind of Drinking water pail cover according to claim 1 is characterized in that: the degree of dip of the outer of described sealing band (1), be close to the bucket neck arc outer wall be complementary.
3, a kind of Drinking water pail cover according to claim 1 is characterized in that: in the described sealing band fulcrum (2,3), upper end fulcrum (2) is shorter than lower sustainer (3), protrudes lower sustainer (3) slightly.
4, according to claim 1 or 3 described a kind of Drinking water pail covers, it is characterized in that: described sealing band (1) fulcrum rear end is provided with the groove (5) of dilatation when fulcrum is squeezed.
5, according to claim 1 or 3 described a kind of Drinking water pail covers, it is characterized in that: outer two fulcrums (2,3) of described sealing band (1) are close to up section of the arc outer wall of barrel neck, it is the backing ring of arc (4) that a cross section is arranged on descending section cooresponding bung of this arc outer wall, cooperates the arc outer wall of clamping bucket neck up and down with sealing band (1).
