Abstract
The utility model relates to a terminal post hole of a lead-acid battery cover; the inner wall of the terminal post hole is a flare opening shape, the upper part of which is big, and the lower part thereof is small; the design of a taper structure on the inner wall of the terminal post hole has the advantages that: firstly, the assembly is convenient; as the taper structure on the inner wall of the terminal post hole has a guiding function to a sealing ring entering the sealing part in the assembling process of the sealing ring, thus greatly improving the reliability of assembling operation of the sealing ring of a terminal post; secondly, as the assembling pressure of the sealing ring is gradually increased, the sealing ring can be stably blocked at the bottom part of the terminal post hole after the sealing ring is assembled in the terminal post hole, thus obtaining good sealing effect.
Description
Technical field
The utility model relates to a kind of lead acid accumulator battery cover pole hole.
Technical background
At present, the seal form in lead acid accumulator battery cover pole hole has a variety of, wherein extensively a kind of of employing is acid-resisting rubber circle seal form: the pole of lead acid accumulator battery upwards passes from lead acid accumulator battery cover pole hole, bottom, pole hole is provided with the O shape circle that is sleeved on the pole, and the top of O shape circle is sealed with epoxy glue.When battery assembles, sealing ring is enclosed within earlier on the pole, be assembled to the bottom in battery cover pole hole then from top to bottom.Because existing lead acid accumulator battery cover pole hole inwall is equal diameters up and down, all adopt tight assembling between sealing ring and the battery cover pole hole, between sealing ring and the pole, so when assembling, sealing ring one is the bottom that is difficult for being directed into battery cover pole hole, the 2nd, very easily cause the not in place or sealing ring distortion of sealing ring assembling, cause battery cover pole hole place sealing effectiveness not good, produce and leak glue, climb phenomenon such as acid.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of lead acid accumulator battery cover pole hole of being convenient to assemble, install good airproof performance is provided.
Technical solutions of the utility model: a kind of lead acid accumulator battery cover pole hole, its difference is: the big up and small down horn mouth shape of described pole hole inwall.
By above scheme, described horn mouth vertical section is the inversion isosceles trapezoid.
By above scheme, described bell-mouthed tapering is 90.5 °-96 °.
By above scheme, described bell-mouthed tapering is 91 °-93 °.
By above scheme, the aperture in described pole hole is the notch cuttype aperture.
The contrast prior art, the beneficial features of technical solutions of the utility model is:
1, pole hole inwall is provided with down the little big tapering of; The design first of pole hole inwall tapered configuration is to have made things convenient for assembling, because in the sealing ring assembling process, the tapered configuration of inwall plays guide effect to the sealing ring that enters the sealing position, improves the reliability of electrode column sealing circle assembly manipulation greatly; The secondth, because the assembling pressure that sealing ring is subjected to increases gradually, can obtain excellent sealing effect thereby can firmly be stuck in bottom, pole hole after sealing ring is seated in the pole hole.
2, tapering is 90.5 °-96 °.Because the angle of pole pass chamber vertical section is also unsuitable excessive, otherwise can cause the resilience of electrode column sealing circle; So in actual design, requiring tapering is 90.5 °-96 °, such design can realize the reliability of electrode column sealing ring manipulation and the stability of cell sealing.
3, tapering is 91 °-93 °, and one can provide better sealing ring assembly reliability, the 2nd, make that the sealing at place, polar post of lead acid batteries hole is more good.
4, notch cuttype aperture, because the orifice diameter in pole hole made things convenient for and poured epoxy glue into the pole hole greater than the diameter of pole hole inwall, and also better appearance of outward appearance.
The utility model is simple in structure, cost is low.

Specific embodiments
The utility model embodiment as shown in Figure 1, a kind of lead acid accumulator battery cover pole hole, the big up and small down horn mouth shape of described pole hole 1 inwall, the horn mouth vertical section is the inversion isosceles trapezoid.The horn mouth cross-sectional diameter from top to bottom reduces gradually, and whole pole hole forms up big and down small horn mouth shape.In Fig. 1, the A size is slightly larger than the B size, can realize that like this pole hole cross section reduces gradually from top to bottom.Whole pole hole inwall is the horn mouth shape, and pole hole inwall has tapering α; Tapering α is unsuitable excessive, otherwise can cause the resilience of sealing ring.
In actual design, the tapering α in pole hole 1 is traditionally arranged to be 90.5 °-96 °; The tapering α in pole hole 1 also can be arranged to 91 °-93 °, and such one can make the assembling of sealing ring in the pole hole more reliable, and two can guarantee the sealing stability of lead-acid storage battery terminal.The aperture in described pole hole can be set to the notch cuttype aperture.
Above embodiment is preferred embodiment of the present utility model; be not that utility model is done any type of restriction; every foundation technological essence of the present utility model all still belongs in the protection range of the present utility model any simple modification, equivalent variations and modification that above embodiment did.
