The utility model content
The purpose of this utility model be to provide a kind of simple in structure, can reuse, effectively reduce the battery scrappage, reduce the explosion protection for batteries of battery production cost.
To achieve these goals, the technical solution adopted in the utility model is:
Described explosion protection for batteries comprises cylinder, opens hole I at an end center of described cylinder, and hole II is opened at other end center; The aperture of described through hole I is greater than through hole II; Joint at described through hole I and through hole II is provided with spheroid; One side of described spheroid is stuck on the described through hole II, and opposite side is provided with spring; Described spring is located at the inside of described through hole I and is withstood described spheroid.
As further improvement, the position that joins at described spheroid and described through hole II is provided with sealing ring.
As further improvement, on cylinder one end that has through hole I, be provided with lid, on described lid, be provided with bleeder port.
As further improvement, the described cylinder outside is a helicitic texture.
As further improvement, described lid and described cylinder are by being threaded.
As further improvement, described explosion protection for batteries is connected on the battery by nut, is connected with positive terminal and negative terminal on battery, and described explosion protection for batteries is located between positive terminal and the negative terminal.
Advantage of the present utility model is: described explosion protection for batteries, described spheroid forms sealing with described through hole II under the effect of described spring, when cell internal pressure increase to surpass described spring to the active force of described spheroid, spheroid will be backed down, cell internal pressure is by releasing in the slit between spheroid and through hole II, and via through holes I slowly releases, and cell internal pressure will reduce, thereby reach the purpose that prevents battery explosion.After cell internal pressure reduced, described spheroid was forming sealing once more and between described through hole II under the effect of described spring; When cell internal pressure increased once more, spheroid will be backed down once more, and cell internal pressure plays the effect that prevents battery explosion once more by releasing in the slit between spheroid and through hole II.Reciprocal through this, described explosion protection for batteries can continuous action, continues pressure is in time released from battery cover board, and battery can continue to use, and can not go out of use because of not possessing explosion prevention function, can effectively reduce the production cost of battery like this.The utility model is simple in structure, and is easy for installation, with low cost, safe and reliable, can repeatedly use.

Mark among the above-mentioned figure is:
1, battery, 2, positive terminal, 3, negative terminal, 4, explosion protection for batteries, 5, sealing ring, 6, spheroid, 7, spring, 401, cylinder, 402, nut, 406, bleeder port, 407, lid.
Embodiment
Contrast accompanying drawing below, by description to embodiment, to the effect of the mutual alignment between embodiment of the present utility model such as the related each several part and annexation, each several part and operation principle etc., be described in further detail, design of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
As shown in Figure 1, described explosion protection for batteries comprises cylinder 401, opens hole I at an end center of cylinder 401, and hole II is opened at other end center; The aperture of through hole I is greater than through hole II; Joint at through hole I and through hole II is provided with spheroid 6; One side of spheroid 6 is stuck on the through hole II, and opposite side is provided with spring 7; Bullet 7 springs are located at the inside of through hole I and are withstood spheroid 6.
Spheroid 6 forms sealing with through hole II under the effect of spring 7, when cell internal pressure increases the active force that surpasses 7 pairs of spheroids 6 of spring, spheroid 6 will be backed down, cell internal pressure is by releasing in the slit between spheroid 6 and through hole II, and via through holes I slowly gushes, cell internal pressure will reduce, thereby reach the purpose that prevents battery explosion.
For guaranteeing the reliability of described explosion protection for batteries work, spheroid 6 must be good with the sealing property of through hole II, as further improvement, be provided with sealing ring 5 in spheroid 6 and the position that through hole II joins, sealing ring 5 is used to guarantee to have excellent sealing performance between spheroid 6 and through hole II.
