The gap that section is isosceles trapezoid is formed between left and right bridge adjacent face and supporting part upper surface, section is provided with gap
For the skeleton of isosceles trapezoid, there is the seal groove laterally set in the left and right sidewall of the skeleton, be connected with the top of the skeleton convex
Block, projection support the elastic cover plate of top, and elastic cover plate upper surface is concordant with the upper surface of left and right bridge, the skeleton
Sealing gasket is fitted with inclined-plane, sealing gasket medial surface is connected with the sealing block being adapted with seal groove, and sealing block is located at seal groove
Interior, the lateral surface of the sealing gasket is fitted on bridge end face, and the top both sides of the skeleton are symmetrically arranged with top sealing block,
The top sealing block outer face is fitted on bridge end face, and the first elastic component, institute are provided between top sealing block and projection
The two bottom sides for stating skeleton are symmetrically arranged with sealed bottom block, and the sealed bottom block outer face is fitted on bridge end face, bottom
Portion sealing block bottom is fitted in supporting part upper surface, and the second elastic component is provided between two sealed bottom blocks.
Said structure, left and right bridge deformation cause gap to become hour, inside crush seal pad, top sealing block and bottom
Sealing block；When gap change is big, the first elastic component and the second elastic component push out top sealing block and sealed bottom block, pass through
The outer inclined-plane of sealing gasket, top sealing block and sealed bottom block and bridge end face are bonded the sealing for realizing bridge end face, pass through
Seal groove and sealing block upper and lower surface be bonded and skeleton and top sealing block and sealed bottom block upper and lower surface are bonded reality
The sealing of existing skeleton；Elastic cover plate upper surface between gap is concordant with bridge upper surface, when vehicle passes through, reduces vehicle
Jolt, when gap diminishes, elastic cover plate, which is extruded inward, to be heaved, due to the elasticity of elastic cover plate itself and the bottom of skeleton bottom
The elastic reaction of portion's sealing block so that vehicle presses through elastic cover plate, and elastic cover plate deforms downwards, while skeleton also deforms downwards,
Reduce because elastic cover plate heaves and caused by jolt sense.
Preferably, the skeleton is integrally formed with projection.
Preferably, the lateral surface of the sealing gasket is connected with the sealing strip of some horizontal stripe shapes, the sealing strip is located at bridge
In the cell body being adapted on beam-ends face with sealing strip.Pass through the mutual cooperation of sealing strip and cell body so that bridge end face seal can
Lean on.
Preferably, the sealing gasket is integrally formed with sealing block.
Preferably, the sealing gasket is integrally formed with top sealing block.The sealing gasket is integrally formed with sealed bottom block.
Sealing gasket is integrally formed with top sealing block, sealed bottom block, and when the first elastic component and the second elastic component, to push out top close
When sealing block and sealed bottom block, outside is pushed to together with sealing gasket so that sealing gasket is combined closely with bridge end face, increase
The reliability of sealing.
Preferably, being symmetrically arranged with two support blocks between the skeleton and supporting part, the second elastic component is located at two branch
Between bracer.If skeleton is supported by sealed bottom block, automobile by when, frequently pressure is easily by sealed bottom sealing block
Damage, the damage of sealed bottom block influence the sealing function of sealed bottom block, and it is excessive to also result in the downward amoeboid movement of skeleton, makes
Obtain elastic cover plate to sink, increase the sense of jolting when automobile passes through, therefore special support block is set, pass through support block support rib
Frame, sealed bottom block is protected, also ensure that skeleton deforms in rational scope；Second elastic component pushes out support block,
By support block to external compression sealed bottom block so that sealed bottom block compresses the end face of bridge, reaches good sealing effectiveness.
The beneficial effects of the utility model are：The utility model is simple in construction, and manufacturing cost is relatively low, by sealing gasket, close
Envelope block, top sealing block, sealed bottom block seal to gap, sealed reliable；By the cooperation of elastic cover plate and skeleton, increase
The ride comfort that strong automobile passes through, reduces sense of jolting.
