Inwall, and have certain length in the vertical, the support member can resist the deformation of insulating cylinder generation, hollow absolutely so as to improve this
The flexing resistance of edge.Further, since the support member can be separately manufactured with the insulating cylinder, manufacture method is simple.Relative to increase
The modes such as the wall thickness of insulating cylinder, the support member can adjust shape and support angle, can save material, can also there is tendency
Property the anti-bending strength increased on the insulating cylinder some direction.
Preferably, above-mentioned support member is extended longitudinally inward by the end of above-mentioned insulating cylinder.One end of the support member is fixed on
It end, can be directly anchored on the flange of end, can prevent the support member from being moved in the insulating cylinder；Because the support member is set
In the end of the hollow insulator, the flexing resistance of end can be effectively improved, and in actual motion, the end of hollow insulator is general
Meeting stress compares concentration.
Preferably, above-mentioned support member radially comprises at least two support ends in the insulating cylinder, the support end against this
The inwall of insulating cylinder.
It is further preferable that the cross section of the support member cross section is cross structure.It is further preferable that the four of the cross structure
Individual end is four above-mentioned support ends, the inwall of the insulating cylinder to should four support ends of support member be provided with corresponding to four
Groove.The design of the groove can prevent the support member from the rotation in circumference occurring in the insulating cylinder, so that influenceing anti-bending strength.
The support member of the cross structure of four support ends can make insulator be improved a lot in the anti-bending strength in length and breadth in both direction.
It is further preferable that the cross structure of above-mentioned support member is centrally located on the axis of the insulating cylinder.The support member of the cross structure
It is evenly distributed with respect to axle center, the center of gravity of the hollow insulator is located on axis, stress is evenly.It is further preferable that above-mentioned branch
The cross section at support end is T font structures, and the top surface of the T fonts abuts the inwall of the insulating cylinder.The structure of the T fonts can effectively prevent
Stress concentration only occurs at above-mentioned support end, prevents from producing destruction to the insulating cylinder.
Preferably, above-mentioned support member cross section is equilateral triangle.The supporting piece structure of the triangle is more stable, except energy
The anti-bending strength of the hollow insulator is greatly improved, also advantageously improves other mechanical performances.Because the support member is hollow
Structure, the hollow insulator will not be also hindered in other centrally disposed components.
Preferably, the equal length of the longitudinal length of above-mentioned support member and the insulating cylinder.The length of the support member makes this exhausted
The support member is supported by edge cylinder, makes each several part anti-bending strength in insulating cylinder balanced, and be not likely to produce stress concentration.
Preferably, the longitudinal length of above-mentioned support member is the half of the length of the insulating cylinder, and the hollow insulator includes two
The individual support member, two support members are separately fixed at the both ends of the insulating cylinder.Two support members can be by the insulating cylinder
Both ends are respectively put into, and prevent from being difficult to smoothly insert in the insulating cylinder because support member is long.
Preferably, the full insulating materials of filling in above-mentioned insulating cylinder.The insulating materials can be put into the insulating cylinder in support member
Fill, solidified afterwards afterwards.
