The radiator front end of water-cooled engine is cold air, and rear end is generally ined succession enging cabin, there is hot-air generation.For
Convenient for checking enging cabin, the sealing of radiator is generally required to obtain in such a way that the flexible materials such as sponge compress.
Due to compression, causes hood that can constantly cut in opening process, pulls the flexible materials such as sponge, in turn result in sealing
Structure is destroyed, and the hot wind of enging cabin is caused to enter radiator front end, and it is excessively high to further result in engine water temperature, influences engine
Service life.
Utility model content
The technical problems to be solved in the utility model is：In order to overcome the sealing of traditional water-cooled engine radiator logical
The problem of mode for crossing the compression of the flexible materials such as sponge obtains, and sealing structure is more easily damaged, and influences engine life, provides one
Kind is for the sealing structure between movable part.
Technical solution adopted by the utility model to solve its technical problems is：A kind of sealing knot between movable part
It is provided with air bag at structure, including hood, radiator and cylinder, the radiator and hood closure, the air bag and cylinder pass through
Gas tube is connected to, and is slidably fitted with piston in the cylinder, is formed seal cavity, the work between the piston and cylinder body bottom
It is fixedly installed with piston rod beyond the Great Wall, the piston rod stretches out the cylinder, is provided with piston reset device in the seal cavity,
When hood is closed, hood pushes piston compression seal cavity, and cylinder is inflated into air bag, sealed heat-dissipating device and hood；Hood is opened
Qi Shi, piston reset extract gas in air bag out.
The sealing structure being used between movable part of the utility model, when hood is closed, hood pushes piston rod, piston
Bar pushes piston compression seal cavity, and the intracorporal gas of seal chamber enters air bag by gas tube, to carry out to air bag automatic
Inflation, air bag volume expansion, and then sealed heat-dissipating device and hood guarantee sealing effect；When hood needs to open, piston reset
Piston reset, the space of seal cavity are increased, the gas in air bag are extracted out, air bag volume contraction will not be by hood by device
It scratches, avoids air bag friction damage.
In order to simplify the integral installation structure of the utility model, the piston reset device is Self-resetting spring, it is described from
One end of reset spring is fixedly connected with the piston, and the other end is fixedly connected with cylinder body bottom, and when hood is closed, piston compression is certainly
Reset spring；When hood is opened, automatic-reset spring resets, and pushes piston reset.
In order to realize that better seal hood and radiator, the air bag are fixed at the surface of radiator.
Piston rod damages hood in order to prevent, and the one end not connecting with piston on the piston rod is fixedly installed with
Push plate, push plate increase the contact area of piston rod and hood, reduce the damage to hood.
The utility model has the beneficial effects that:The sealing structure being used between movable part of the utility model is closed in hood
When closing, hood pushes piston rod, and piston rod pushes piston compression seal cavity, and the intracorporal gas of seal chamber is entered by gas tube
Air bag guarantees sealing effect to carry out automatic inflating, air bag volume expansion, and then sealed heat-dissipating device and hood to air bag；?
When hood needs to open, piston reset, the space of seal cavity are increased, the gas in air bag are extracted out by piston reset device,
Air bag volume contraction will not be scratched by hood, avoid air bag friction damage.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
