Problems solved by technology

The invention provides a lead-acid battery cover. When the cover sheet of the battery cover is bonded to the cover body, the glue is not easy to block the exhaust passage, so that the gas inside the battery can be discharged in time, preventing the internal pressure of the battery from rising and causing the battery to burn. bloat problem

Embodiment 1

[0020] Embodiment 1: a kind of lead-acid battery cover (referring to attached figure 1 , attached figure 2 , attached image 3 ), including a rectangular cover body 1 and a rectangular cover piece 2, a rectangular cover piece installation groove 3 is provided on the upper surface of the cover body, and two rows of accommodating slot holes 4 are provided on the bottom surface of the cover piece installation groove, and each row is provided with three accommodating slots Hole, a liquid injection hole 5 is provided in the accommodation slot, the cover sheet is bonded and installed in the cover installation slot, and an exhaust slot 6 is arranged between the adjacent two accommodation slots set in the same row, and the exhaust slot They are all arranged on the lower end surface of the cover sheet, and the two ends of the exhaust groove are respectively connected with the two accommodating slots, and the long side air outlet groove 7 is arranged between the adjacent two exhaust g...

Embodiment 2

[0022] Embodiment 2: a kind of lead-acid battery cover (referring to attached Figure 4 , attached Figure 5 ), its structure is similar to that of Embodiment 1, the main difference is that in this embodiment, the lower end surface of the cover sheet is provided with wide-side air outlet slots near the two ends of each row of accommodating slots, and the side wall of the cover sheet installation groove and the width The side air outlet slots are provided with blast holes 11 one by one. The blast holes run through the cover body. The opening size of the blast holes increases gradually from the inside to the outside. The air holes are relatively arranged one by one. The cross section of the blowing hole is a rectangular structure, the width of the blowing hole gradually increases from the inside to the outside, and the height remains unchanged. An acid filter sheet 12 is arranged in the blast hole.

[0023] On the one hand, the blower hole is used as exhaust; on the other han...

Abstract

The invention discloses a lead-acid storage battery cover and aims at solving the defect that a storage battery is expanded, and even burst in a serious condition, as the gas inside a storage battery cannot be immediately discharged and the air pressure of the interior of the storage battery is increased because a glue is easy to block an exhaust passage when a cover sheet is adhered on a cover body. The lead-acid storage battery cover comprises a cover body and a cover sheet, wherein a cover sheet mounting slot is formed in the upper end face of the cover body, a plurality of rows of accommodating slotted holes are formed in the bottom of the cover sheet mounting slot, the interior of each accommodating slotted hole is provided with an injection hole, the cover sheet is adhered in the cover sheet mounting slot, an air discharge duct is arranged between every two adjacent accommodating slotted holes in the same row, the air discharging ducts are formed in the lower end face of the cover sheet, two ends of each air discharging duct are respectively communicated with the two adjacent accommodating slotted holes, a long-side air discharging groove is arranged between every two adjacent air discharging ducts in the same row in the lower end face of the cover sheet and is arranged at the edge of the cover sheet, and long-side air outlets communicated with the long-side air discharging grooves are formed in the position, close to the long-side air discharging grooves, of the edge of the cover sheet.

Description

technical field [0001] The invention relates to a lead-acid battery, more specifically, it relates to a lead-acid battery cover with smooth exhaust. Background technique [0002] Lead-acid batteries will emit a small amount of gas at the end of charging, usually through the exhaust channel on the lead-acid battery cover. The battery cover is generally composed of a cover body and a cover sheet. In order to prevent the cover sheet from loosening, glue is added to the cover body to stick the cover sheet. When gluing the cover, use glue such as chloroform or ABS. When adding glue to the cover, employees should be careful not to drop the glue into the exhaust channel. However, due to the different methods of adding glue by employees or the movement of the battery during operation, it is inevitable that the glue will overflow into the exhaust channel, and under the action of gravity, the glue will also flow into the exhaust channel, thus Block the exhaust passage. Once the exh...
