Abstract
The utility model relates to a dumbbell-shaped sealing strip. The dumbbell-shaped sealing strip comprises a sealing strip body and sealing strip end parts, wherein the wall thicknesses of the sealing strip end parts are greater than that of the sealing strip body, lug bosses are arranged on the sealing strip end parts, and transition step surfaces are arranged between the lug bosses and the sealing strip body. According to the dumbbell-shaped sealing strip, the wall thickness of a splicing part between every two adjacent sealing strip end parts can be increased by the structural design, the casting finished product ratio can be improved, and the wear resistance of the sealing strip can be improved; meanwhile, the sealing effect of the splicing part between every two sealing strip end parts is better due to the design of the lug boss.
Description
Technical field
The utility model relates to a kind of Stamping Steel Ribbon, relates in particular to a kind of Stamping Steel Ribbon for sealing between being listed as using into formula grate-cooler that is listed as.
Background technique
Be listed as into the labyrinth seal structures that adopt of sealing between the row of formula grate-cooler more, by the labyrinth seal structure that constitutes of inside and outside Stamping Steel Ribbon, avoid leakage material between row.Meanwhile, the leakage material for fear of same row to adjacent seals bar seam crossing, is generally designed to concavo-convex nested bridging arrangement by end joint place of adjacent seals bar.Be listed as into the restriction of formula grate-cooler structure, the wall thickness of Stamping Steel Ribbon is limited, and this causes the concavo-convex nested structure thickness of Stamping Steel Ribbon end joint place partially thin, makes troubles to Foundry Production, and the yield rate of foundry goods is not high, and cost of production is high.
Model utility content
Technical problem to be solved: provide a kind of yield rate that improves foundry goods for above problem the utility model, a kind of dumbbell shape Stamping Steel Ribbon reducing production costs.
Technological scheme: provide a kind of dumbbell shape Stamping Steel Ribbon in order to overcome the above problems the utility model, comprised weatherstrip body, Stamping Steel Ribbon end, is characterized in that: the wall thickness of Stamping Steel Ribbon end is greater than the wall thickness of weatherstrip body.
Described Stamping Steel Ribbon end is provided with boss, is provided with transition terrace between boss and weatherstrip body.
Beneficial effect: structural design of the present utility model increases the wall thickness of adjacent seals bar end lap-joint, improves the yield rate of casting, also helpful for the wear resistance of improving Stamping Steel Ribbon.The design of boss simultaneously also makes the sealing effect of Stamping Steel Ribbon end lap-joint better.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the rear view of Fig. 1.
Fig. 3 is end of the present utility model lap-joint enlarged diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figures 1 to 3, the utility model provides a kind of dumbbell shape Stamping Steel Ribbon, comprises weatherstrip body 1,
Stamping Steel Ribbon end 2, the wall thickness of Stamping Steel Ribbon end 2 is greater than the wall thickness of weatherstrip body 1.Stamping Steel Ribbon end 2 is provided with boss 3, between boss 3 and weatherstrip body 1, is provided with transition terrace 4.
This structural design increases the wall thickness of adjacent seals bar lap-joint, improves the yield rate of casting and the sealing effect of Stamping Steel Ribbon end lap-joint, for the Foundry Production of Stamping Steel Ribbon offers convenience, has also improved the reliability of actual use.
The foregoing is only preferred embodiment of the present utility model, be not restricted to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present utility model.
