Abut.Therefore, the effect of the sealing effectiveness strengthening push pedal is played in the setting of rubber ring.
This utility model is further arranged to：Multiple annulars snapping in for rubber ring are provided with the inwall of described fusion tube
Groove.
By adopting technique scheme, when two pieces of push pedals are transported under the gas effect between two pieces of push pedals in the opposite direction
When dynamic, rubber ring can constantly repeat to enter cannelure to the process leaving cannelure.And in this process, rubber ring enters ring
During shape groove, compressive deformation reduces, and leaves compressive deformation during cannelure and increases, thus the heat of gas is constantly converted, thus
Air pressure is made to reduce.Simultaneously as rubber ring constantly repeats to enter cannelure to the process leaving cannelure, extend the work of gas
With the time, copper cap is therefore made to avoid causing the situation of explosion to occur because of the moment impact by gas further.
This utility model is further arranged to：The section of described cannelure is semicircle.
By adopting technique scheme, the section of cannelure is semicircle, facilitates rubber ring to snap in cannelure and rubber
Cushion rubber leaves cannelure.If cannelure is square, then rubber ring is just difficult to exit once snapping in, thus lead to two pieces of push pedals and
Fusion tube body forms fixing confined space, then fusion tube is easily subject to the effect of gas to cause the situation of explosion to occur.
This utility model is further arranged to：The section of described rubber ring is hemispherical.
By adopting technique scheme, the section of rubber ring is identical with the section of cannelure, makes rubber ring snap in annular
During groove, rubber ring can be fitted tightly with the inwall of cannelure, strengthens sealing property.
This utility model is further arranged to：Multiple described cannelures are along the length direction equidistantly distributed of fusion tube.
By adopting technique scheme, multiple cannelure equidistantly distributeds are such that it is able to equidistantly carry out rubber ring
The switching of deformed state.
In sum, this utility model has the advantages that：
It is welded and fixed with copper cap compared to contact knife termination, by copper cap and contact knife termination integrally connected, then copper cap and contact knife end
The bonding strength of head is significantly improved.The setting of manhole is played enables contact knife termination and electric wire to be attached making
With.Contact knife termination is overlapped with the diameter of copper cap, so that the center of gravity of fuse is concentrated on axial line, strengthens stablizing of fuse
Property.

Specific embodiment
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
Field technique personnel can make to the present embodiment after reading this specification as needed does not have the modification of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
With reference to Fig. 1,2 and 3, a kind of automotive fuse, including fusion tube 1.Middle within fusion tube 1 is provided with fuse 2,
It is filled with quartz sand simultaneously.Fuse 2 is distributed in the gap of quartz sand.Two ends within fusion tube 1 are provided with push pedal 3, two pieces
Push pedal 3 all can be slided along fusion tube 1.Fuse 2 and quartz sand are respectively positioned between two pieces of push pedals 3.On the circumference of two pieces of push pedals 3 all
It is provided with rubber ring 4, rubber ring 4 is fixedly connected with the circumferential edges of push pedal 3, can be adhesively fixed using glue.Rubber ring 4
Section be semicircle.Under the extruding of push pedal 3 and fusion tube 1 inwall, rubber ring 4 is in compressive deformation state all the time.In push pedal 3
Multiple cannelures 5 are provided with the inwall sliding the part fusion tube 1 that need to pass through along fusion tube 1, the section of each cannelure 5 is half
Circular.When push pedal 3 is slid into rubber ring 4 along fusion tube 1 and is alignd with cannelure 5, fusion tube 1 inwall that rubber ring 4 is subject to squeeze
Pressure reduces, and the deformation of rubber ring 4 reduces, and rubber ring 4 can snap in cannelure 5.Multiple cannelures 5 are along the length side of fusion tube 1
To equidistantly distributed.
With reference to Fig. 1,2 and 3, outside the two ends of fusion tube 1, all it is installed with copper cap 6, copper cap 6 includes connect fixing with fusion tube 1 end
The connecting portion 61 connecing and the closure 62 of closing fusion tube 1 end.The closure 62 of copper cap 6 deviate from fusion tube 1 side be provided with tactile
Knife termination 7, contact knife termination 7 is overlapped with the diameter of copper cap 6.Manhole 8, the axle of manhole 8 are provided with contact knife termination 7
Line is vertical with the axis of fusion tube 1.
With reference to Fig. 1,2 and 3, push pedal 3 is connected to elastic component 9, and elastic component 9 is away from the one end being connected with push pedal 3 and copper cap 6
Closure 62 connects.Preferably, elastic component 9 is spring.
Work process：When the electric current through overcurrent fuse is excessive, fuse 2 generation heat is larger, leads to fuse 2 to fuse.And
Air in fuse absorbs the heat volumetric expansion that fuse 2 produces, and the air pressure in fuse increases.When gas acts on push pedal
When on 3, push pedal 3 power under spring action is less than the active force by gas, and push pedal 3 starts to move to copper cap 6, and spring occurs
Compression, produces elastic deformation.In the motor process of push pedal 3, push pedal 3 can be through multiple cannelures 5.Through each cannelure 5
When, the compressive deformation of the rubber ring 4 on push pedal 3 circumference reduces, and leaves compressive deformation during cannelure 5 and increases.And in rubber ring 4
During deformed state constantly changes, the heat of gas is constantly delivered on fusion tube 1 in the form of doing work, makes gas
Heat reduce, air pressure reduce.Meanwhile, in push pedal 3 moving process, there is compressive deformation in spring, when extending gas effect
Between.And because rubber ring 4 constantly repeats to enter cannelure 5 to the process leaving cannelure 5, also extend gas effect when
Between, so that copper cap 6 avoids causing the situation of explosion to occur because of the moment impact by gas.
