Chinese patent CN 2779188Y discloses a kind of new type explosion proof valve, is the structure of on Battery case, suppressing trace, and the impression part is relatively weaker; When gas pressure arrives to a certain degree; The impression place can be broken through, thereby helps reducing pressure, avoids storage battery to blast.But there is the problem that is difficult for processing in the impression of this structure, and the degree of depth of impression often is difficult to accurately control; Simultaneously, it does not have the function of regulating cell box internal pressure, and explosion-proof reliability is difficult to guarantee.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the present invention provides a kind of explosion proof forklift of reliable operation with storage battery automatic Regulation explosion-protection equipment.
Technical scheme of the present invention is: it comprises the automatic Regulation explosion-protection equipment body of being located on the battery case; Be provided with the pressure adjusting slider in the automatic Regulation explosion-protection equipment body interior cavity, the pressure adjusting slider is with automatic Regulation explosion-protection equipment body interior cavity separated into two parts, and a part is the balancing gate pit; Another part is a communication chamber; Pressure chamber wall is provided with the high pressure gas inlet, is provided with sealing fastener in the high pressure gas inlet, and communication chamber communicates with battery case inside; Automatic Regulation explosion-protection equipment body top is provided with the exhaust outlet with atmosphere; Pressure adjusting slider top contacts with the exhaust outlet lower limb, and automatic Regulation explosion-protection equipment body bottom is provided with the guide vane end stop that the pressure adjusting slider is played the role of positioning, and guide vane end stop contacts with pressure adjusting slider bottom.
Further, the preferred I shape slide block of said pressure adjusting slider, promptly the slide block cross section is an I shape.
Further, said pressure adjusting slider also can be the hexahedron slide block, and the slide block cross section is a rectangle.
Further, said sealing fastener can be bolt.
Further, said exhaust outlet top is provided with screen pack, and is inner to prevent that foreign matter from getting into battery case.
Further, said guide vane end stop and automatic Regulation explosion-protection equipment body are structure as a whole, and guide vane end stop also can be by protruding substituting of being located at automatic Regulation explosion-protection equipment body bottom.
Further, said automatic Regulation explosion-protection equipment body is realized being connected through bolt or welding manner and battery case.
Further, said automatic Regulation explosion-protection equipment body is located on the battery case case lid.
The present invention is simple in structure, compact, and processing and manufacturing is more or less freely, can realize automatic Regulation, reliable operation, and the maximum pressure value that the balancing gate pit can bear can be adjusted according to the battery pack specification, is applicable to the battery combination of different volumes specification.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Embodiment 1
With reference to Fig. 1,2, present embodiment comprises the automatic Regulation explosion-protection equipment body of being located on the battery case 23, is provided with pressure adjusting slider 7 in automatic Regulation explosion-protection equipment body 3 internal cavities; Pressure adjusting slider 7 is with automatic Regulation explosion-protection equipment body 3 internal cavities separated into two parts; A part is balancing gate pit 8, and another part is a communication chamber 9, and balancing gate pit's 8 walls are provided with high pressure gas inlet 10; Be provided with sealing fastener 11 in the high pressure gas inlet 10; Communication chamber 9 communicates with battery case 2 inside, and automatic Regulation explosion-protection equipment body 3 tops are provided with the exhaust outlet 4 with atmosphere, and pressure adjusting slider 7 tops contact with exhaust outlet 4 lower limbs; Automatic Regulation explosion-protection equipment body 3 bottoms are provided with the guide vane end stop 6 that pressure adjusting slider 7 is played the role of positioning, and guide vane end stop 6 contacts with pressure adjusting slider 7 bottoms.
Said pressure adjusting slider 7 is the I shape slide block.
Said sealing fastener 11 is a bolt.
Said exhaust outlet 4 tops are provided with screen pack 5, and it is inner to help preventing that foreign matter from getting into battery case.
Said automatic Regulation explosion-protection equipment body 3 is realized being connected through bolt and battery case 2.
