Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

A kind of accumulator cap, including the middle cover 10 and cover plate 20, as shown in figure 1, the top of the middle cover 10 has cover plate slot to hold the said cover plate 20, the side wall of the cover plate slot has supporting steps 11 for setting up the said cover plate 20, the bottom of the cover plate slot has acid-adding hole columns 12, the acid-adding hole column 12 has acid-adding hole in the middle, the bottom of the said cover plate slot also has several supporting frames 30,

as shown in fig. 2, a clamping groove 21 is provided on the bottom surface of the cover plate 20 and is clamped with the top surface of the supporting frame 30.

The cross section of the support frame 30 is T-shaped, and comprises a first support plate 31 arranged along the length direction of the middle cover 10 and a second support plate 32 arranged perpendicular to the first support plate 31 and connected with the middle part of the first support plate 31.

After the support frame 30 with a cross section in a T shape formed by connecting the first support plate 31 and the second support plate 32 is fastened with the clamping groove 21, the cover sheet 20 can be prevented from moving in four directions, which is more favorable for maintaining the stability of the position of the cover sheet 20.

The edge setting that first backup pad 31 is close to the cover plate groove, second backup pad 32 is close to the centre setting in cover plate groove, draw-in groove 21 corresponds on the support frame 30 of T shape first backup pad 31 deviates from second backup pad 32 one side fluting setting.

Because the first supporting plate 31 is arranged close to the edge of the cover plate groove, the clamping groove 21 is designed to correspond to the structure that the groove is formed in one side, deviating from the second supporting plate 32, of the first supporting plate 31 on the T-shaped supporting frame 30, so that interference can be prevented, and the clamping groove 21 can be buckled on the supporting frame 30 more conveniently.

The support frames 30 comprise two rows, and the two rows of support frames 30 are respectively positioned at two sides of the row of the acid adding hole columns 12.

The acid hole columns 12 can provide a certain supporting force for the middle part of the cover plate 20, the supporting steps 11 can provide a certain supporting force for the edge of the cover plate 20, and the supporting frames 30 are arranged on two opposite sides of the row of acid hole columns 12 and can provide a certain supporting force for the position between the middle part of the cover plate 20 and the edge of the cover plate 20, so that the structure enables the stress of the cover plate 20 to be more uniform, and the cover plate 20 can be more effectively prevented from being crushed;

the slots 21 on the cover plate 20 are also distributed in two rows, each row having at least two slots 21.

The width of each position of the clamping groove 21 is 0.3 mm-0.5 mm larger than the thickness of each position of the supporting frame 30.

The structure that draw-in groove 21 width is greater than support frame 30 thickness makes things convenient for the dismouting of cover plate 20, simultaneously because first backup pad 31 and second backup pad 32 all have certain height, lead to can producing between the cell wall of draw-in groove 21 and first backup pad 31 and the second backup pad 32 and interfere, and at the in-process that uses of battery, cover plate 20 is difficult to drop from well lid 10.

The supporting frame 30 is integrally formed with the middle cover 10, and the clamping groove 21 is integrally formed with the cover plate 20.

The integrally formed structure stabilizes the position between the support frame 30 and the middle cover 10, stabilizes the position between the cover plate 20 and the slot 21, and is more beneficial to the installation between the middle cover 10 and the cover plate 20.

When the storage battery is used specifically, as shown in fig. 3 and 4, before the storage battery leaves a factory, the cover plate 20 is buckled in the cover plate groove, the supporting step 11 supports the edge of the cover plate 20, and meanwhile, the clamping groove 21 at the bottom of the cover plate 20 is buckled with the supporting frame 30 on the middle cover 10 to provide a certain supporting force for the middle part of the cover plate 20, namely, the edge and the middle part of the cover plate 20 are supported to a certain extent, so that the structure effectively increases the pressure capacity of the cover plate 20, and can prevent the cover plate 20 from being damaged under pressure to a certain extent; in addition, the clamping groove 21 and the supporting frame 30 are buckled and combined with the structure of the cover plate groove, so that the cover plate 20 can be effectively prevented from displacing, the relative position between the cover plate 20 and the middle cover 10 is stable, and the middle cover 10 can be better protected from being damaged.
