The utility model patent of the U of Authorization Notice No. CN 203774155 is pole-mounted circuit breaker.The utility model patent is logical
The bottom for crossing insulation tube cavity sets the fastening swivel nut with insulation tube cavity interference fit to realize the optimization of water resistance.But
There is problems with the method：Because fastening swivel nut and insulation tube cavity are interference fits, easily right when installing
Insulation tube cavity causes to damage, and cannot be reused after detachable maintaining.
Utility model content
It is good that one of purpose of the present utility model is to provide a kind of water resistance, after will not damaging insulation tube, and dismounting
The pole-mounted circuit breaker that can also be continuing with.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of pole-mounted circuit breaker,
Including insulation tube, the top of the insulation tube cavity is provided with vacuum interrupter, and the conducting rod at the top of the vacuum interrupter passes through
Bolt is fixed with insulation tube, and the bottom of the insulation tube cavity is provided with fastening swivel nut, and the insulation tube cavity is provided with one layer of rubber
Layer, the rubber layer is adapted with fastening swivel nut, and the bottom of the rubber layer inwall is provided with serrate projections.
By above-mentioned technical proposal, the conducting rod at the top of vacuum interrupter is fixed and clamped by bolt and insulation tube and is clipped in absolutely
Rubber layer between edge pipe and vacuum interrupter, rubber layer is brought into close contact with conducting rod, insulation tube under pressure, plays close
Effect at the top of envelope insulation tube.The serrate projections of rubber layer inwall can keep away when swivel nut insertion is fastened with the extruding of fastening swivel nut
The surface for fastening swivel nut is got out of the way and be tightly fitted in, fastening swivel nut abjection is also prevented from while sealed insulation bottom of the tube.
Insulation tube will not be damaged during installation, when maintenance needs are dismantled, can also be continuing with after the completion of maintenance.
It is further arranged to：The serrate projections are provided with sawtooth tiltedly towards insulation tube top.
By above-mentioned technical proposal, the sawtooth of serrate projections tiltedly towards insulation tube top can make that fastening swivel nut inserts when
Sawtooth is waited to be avoided with less angle of bend, and after avoiding binding face area it is vertical compared with sawtooth when it is bigger, sealing and
The effect of Anti-extrusion is more preferable.
It is further arranged to：The top of the fastening swivel nut is smooth arc surface.
By above-mentioned technical proposal, the top of swivel nut is fastened for smooth arc surface can make fastening swivel nut be easier to insert rubber
The serrate projections of glue-line, and the sawtooth of serrate projections will not be damaged.
It is further arranged to：The rubber layer and insulation tube are bonded, and the bottom surface of the rubber layer is risen after being provided with compression deformation
The projection of sealing function.
By above-mentioned technical proposal, when insulation tube is fixed in one plane, rubber layer can also be pressed abd fixed on this
In plane, during this time, tightly fitted with the plane after the raised crimp of rubber layer bottom surface, play the effect of secondary waterproof
Really.The setting compares, and to be embedded in O-ring again not only easy to process for recessing, and the step of eliminate mounting O-shaped rings.Rubber layer
It is then whole during relative slip so as to cause rubber layer and contact surface to extrude in order to prevent from occurring between the two with insulation tube bonding
Rubber layer is up compressed so that raised deflection is smaller, after deformation with the fitting area very little of contact surface and cause sealing to be imitated
Fruit is not good.
It is further arranged to：The projection is that section is semicircular annular projection.
By above-mentioned technical proposal, because relative motion will not occur between insulation tube and mounting plane, projection choosing
With the semicircle ring-type similar with O-ring structure, processing will be conveniently compared with X-shaped sealing ring, y-type seal ring.
It is further arranged to：Saucer washer is provided between the bolt and insulation tube.
By above-mentioned technical proposal, butterfly gasket can play locking effect, prevent bolt looseness and cause insulation tube
Top cannot seal.
In sum, the beneficial effects of the utility model are that water resistance is good, easy for installation, and fastening swivel nut will not when installing
Damage rubber layer.
