Set adopts embedded structure, along with material inhomogeneity used by both, so physical property is entirely different, especially with the combination of housing
It is that the important indicator values such as intensity, the thermal coefficient of expansion of material differ greatly.Lead bushing and housing are respective under the conditions of same temperature
Produce corresponding breathing amount, because breathing amount has larger gap, produce the internal stress of certain value therefrom.The internal stress that cannot discharge
Naturally increase the gap between both faying faces, once form gap becoming as the interior leakage passage storing dilute sulfuric acid.Dilute sulfuric acid is
A kind of extremely strong liquid of corrosivity, once oozing out the direct environment deteriorating lead-acid accumulator position, brings to corollary equipment
Corrosion effects.Do numerous studies to reduce dilute sulfuric acid and oozing out in the industry, and successively achieve a lot of application achievements.At present, city
The lead-acid battery sold on field is designed with antiseepage acid structure, and one of which is provided with the concavo-convex phase of multiple tracks on lead bushing outer wall vertically
Between shoulder leakage preventing structure application effect preferably, it makes full use of staggered structure to increase the faying face of lead bushing and housing
And length of fit, its purpose is just to increase oozes sour difficulty, to reduce infiltration capacity.The lead bushing anti-seepage effect of prior art and peripheral hardware
Concavo-convex alternate shoulder quantity is proportional, because being limited by thickness of shell in reality, does not allow lead bushing length overlength, thus existing
The lead bushing having technology can only set the concavo-convex alternate shoulder in 2～3 roads.Although this structure has preferable anti-seepage effect, antiseepage
Thoroughly do not ooze sour problem it is impossible to be inherently eliminated, particularly in the presence of a harsh environment prior art products to ooze sour problem still very tight
Weight.
Content of the invention
Present invention is generally directed to the halfway problem of prior art products antiseepage, a kind of two-way antiseepage formula lead bushing is proposed,
This lead bushing external end face leakage preventing structure is reasonable, it is easy to make, and had both increased the bond strength of lead bushing and housing, and had significantly improved again
Anti-seepage effect.
The present invention is achieved through the following technical solutions technical goal.
Two-way antiseepage formula lead bushing, it thes improvement is that：It is in flange-like member, and central authorities are provided with axial tapered sleeve, tapered sleeve
Outer connection radially-protruding round edge together, is respectively equipped with concavo-convex alternate integrated concentric circular shoulder on round edge upper and lower end face,
At least provided with integrated shoulder together on the outer wall of round edge, thus form two-way leakage preventing structure.
As further improvement project, connect radially-protruding round edge together outside described tapered sleeve, on round edge upper and lower end face
It is respectively equipped with the concavo-convex alternate integrated concentric circular shoulder in 2～5 roads.
As further improvement project, described concentric circular shoulder axial cross section rectangular and trapezoidal shapes.
The present invention compared with prior art, has the positive effect that：
1st, two-way leakage preventing structure is simple, easy to manufacture；
2nd, lead bushing radially-protruding face size degree of freedom is big, sets up and does not change lead bushing length during leakage preventing structure, this structure
Easily supporting with lead-acid accumulator housing；
3rd, set altogether on the round edge upper and lower end face of lead bushing and excircle, at three, concavo-convex alternate antiseepage is formed by concentric circular shoulder
Structure, after it implants housing, both faying faces increase at double, and length of fit also lengthens at double, thus significantly improves junction antiseepage
Ability.
Brief description
Fig. 1 is embodiment of the present invention structural profile schematic diagram, and in figure upper and lower end face respectively sets twice integration concentric circular shoulder,
One annulus is set on excircle.
Fig. 2 is the partial cutaway schematic that Fig. 1 implants in housing.
Fig. 3 is the schematic perspective view of Fig. 1.
Specific embodiment
Below according to accompanying drawing and combine case study on implementation, the invention will be further described.
Two-way antiseepage formula lead bushing shown in the drawings is to ensure that a part of lead-acid accumulator sealing, and this part is implanted
Terminal position is supplied to install among housing.Described lead bushing is in flange-like member, and central authorities are provided with axial tapered sleeve, connects one outside tapered sleeve
The radially-protruding round edge in road, is respectively equipped with concavo-convex alternate integrated concentric circular shoulder on round edge upper and lower end face.The present embodiment
Because supporting lead-acid accumulator specification is less than normal, round edge upper and lower end face is only respectively equipped with twice integration concentric circular as shown in Figure 1
Shoulder, round edge outer wall sets together radially-protruding round platform shoulder, thus forms at three the concavo-convex alternate integrated concentric circular in totally 5 roads
Shoulder.Concentric circular shoulder axial cross section in the present embodiment is rectangular as shown in Figure 1, and the width of this square-section and height
Equal sized.After the embodiment implantation housing shown in Fig. 1, both nearly double than prior art products at faying face, cooperation
Length also lengthens by about one time.Because faying face increases and how tortuous, even if because reason of expanding with heat and contract with cold produces inevitable gap,
Also gradually attenuated by curved surface resistance along the dilute sulfuric acid energy that this gap is oozed out, thus do not ooze the generation of sour problem.In addition, this
Although invention increased several roads leakage preventing structure, really do not need change the original axial length of lead bushing, thus the present invention no matter
Specification size can be accomplished supporting with lead-acid accumulator.
The architectural feature of the present invention is that main body leakage preventing structure is located on end face, the axial antiseepage knot of this structure and prior art
90 ° are differed, the largest benefit that this position adjustment brings is to realize two-sided setting leakage preventing structure, and still member-retaining portion on structure position
Axial leakage preventing structure, in the presence of dual leakage preventing structure, thoroughly solves to ooze sour problem at lead-acid accumulator housing lead bushing.
