It is general, it is also proposed higher and higher requirement to battery capacity, current research direction is mainly consideration in limited space such as
What improves the capacity of battery.Existing ni-mh cylindrical battery is using bound edge block（See accompanying drawing 1）, the bound edge lid of this structure
Cap flange side edge thereof thickness is thicker, and the lower surface protrusion of flange cover plate is more, thus occupies inside battery space,
Limit the capacity of battery.
The content of the invention
The technical problem that the utility model is solved there is provided one kind can effectively improve inside battery space and weight ratio
The cylindrical battery straight flange block of energy and the ni-mh cylinder secondary cell using the straight flange block, the straight flange block of the structure with it is close
After seal and box hat coordinate sealing, by increasing capacitance it is possible to increase the inner space of battery, while reducing the weight of battery, and then battery is improved
Gravimetric specific energy.
The utility model is to solve above-mentioned technical problem to adopt the following technical scheme that, cylindrical battery straight flange block, its feature
Be include the block of convex-shaped flange, middle part be provided with waste gas discharge hole straight flange cover plate and be arranged at the block of convex-shaped flange with it is straight
It is used to compress the explosion-proof ball in straight flange cover plate waste gas discharge hole, flange and the straight flange cover plate of the convex-shaped flange block between the cover plate of side
It is welded and fixed, convex-shaped flange block is provided with multiple air-vents.
Further preferably, on described convex-shaped flange block vertical edge or convex-shaped flange block vertical edge and flange company
The place of connecing is provided with multiple air-vents.
Ni-mh cylinder secondary cell described in the utility model, including box hat, straight flange block and it is packaged in box hat and straight flange
Cylindrical battery core and electrolyte in block, cylindrical battery core are formed by the stacked winding of positive plate, barrier film and negative plate, its feature
It is：Described straight flange block includes that the block of convex-shaped flange, middle part are provided with the straight flange cover plate in waste gas discharge hole and are arranged at
It is used to compress the explosion-proof ball in straight flange cover plate waste gas discharge hole, the convex-shaped flange block between the block of convex flange and straight flange cover plate
Flange be welded and fixed with straight flange cover plate, the vertical edge of convex-shaped flange block and the junction of flange are provided with multiple air-vents.
The utility model increases the inner space of cylindrical battery by changing block profile, flat using straight flange and lower surface
The block of neat structure, increased the inner space of battery, and then can to a certain extent increase the width of pole plate, so as to improve electricity
The capacity in pond.Further, since the weight of straight flange block is less than bound edge block, the weight that can thus effectively improve battery compares energy
Amount so that being more widely applied for battery, has such as obtained preferable application in model plane.

Specific embodiment
Particular content of the present utility model is described in detail with reference to accompanying drawing.Cylindrical battery straight flange block, including convex-shaped flange
Block 1, middle part is provided with the straight flange cover plate 3 in waste gas discharge hole 2 and is arranged between convex-shaped flange block 1 and straight flange cover plate 3 and uses
In the explosion-proof ball 4 for compressing the waste gas discharge hole 2 of straight flange cover plate 3, the flange 5 of the convex-shaped flange block 1 is solid with the welding of straight flange cover plate 3
Fixed, vertical edge 6 and the junction of flange 5 of convex-shaped flange block 1 are provided with multiple air-vents 7.
Ni-mh cylinder secondary cell described in the utility model, including box hat, straight flange block and it is packaged in box hat and straight flange
Cylindrical battery core and electrolyte in block, cylindrical battery core are formed by the stacked winding of positive plate, barrier film and negative plate, described
Straight flange block is provided with the straight flange cover plate 3 in waste gas discharge hole 2 and is arranged at convex-shaped flange including the block 1, middle part of convex-shaped flange
It is used to compress the explosion-proof ball 4 in the waste gas discharge hole 2 of straight flange cover plate 3 between block 1 and straight flange cover plate 3, the convex-shaped flange block 1
Flange 5 is welded and fixed with straight flange cover plate 3, and the vertical edge 6 of convex-shaped flange block 1 is provided with multiple air-vents 7.
Cylindrical nickel-metal hydride battery described in the utility model is by battery pole plates group, electrolyte, straight flange block, sealing ring and box hat
Composition, wherein battery pole plates group are by the nickel positive electrode plate of rectangle, rectangle hydrogen-storage alloy negative plate and are arranged at positive plate and negative plate
