Fig. 3 is that telescopic insulating cylinder of the present utility model faces structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification word to make those skilled in the art.
Should be appreciated that used hereinly such as " to have ", other element one or more do not allotted in " comprising " and " comprising " term or the existence of its combination or interpolation.
As Figure 1-3 be a kind of way of realization according to telescopic insulating cylinder of the present utility model, comprising:
Upper insulating cylinder 1, it is made up of the anti-softening material that insulate, and in the present embodiment, adopts pre-preg epoxy DMD material, shaping through hot setting, according to the class of insulation, the suitably thickness of increase and decrease insulating cylinder.Described upper insulating cylinder 1 is cylindric, described upper insulating cylinder 1 bottom circumferentially on be provided with protuberance 11, described protuberance 11 from top to bottom thickness increases gradually, as shown in Figure 1-2;
Lower insulating cylinder 2, it is made up of the material identical with described upper insulating cylinder 1, described lower insulating cylinder 2 is also cylindric, and diameter is less than the diameter of insulating cylinder 1, described lower insulating cylinder 2 movable upper end is set in the lower end of described upper insulating cylinder 1, described protuberance 11 thickness bottom equals the distance of described upper insulating cylinder 1 outer surface to described lower insulating cylinder 2 outer surface, namely when the outer surface of protuberance 11 flushes with the lateral wall of upper insulating cylinder 1, protuberance 11 lower end supports the lateral wall of insulating cylinder 2 of staying in a circumferential direction, thus fixes upper and lower insulating cylinder; Upper and lower insulating cylinder length is identical, can be inside and outside completely overlapping by upper and lower insulating cylinder, convenient transport, add the change distance in insulating cylinder length simultaneously, effectively increase the scope of application of insulating cylinder, meanwhile, when some location overlap of upper and lower insulating cylinder, construct two insulating barrel structure, effectively improve the dielectric strength between electric equipment products coil, between iron core and coil, between high-tension coil and low-voltage coil;
Rotating parts 3, it is made up of the material identical with described upper insulating cylinder 1, described rotating parts 3 is up and down is set in described protuberance 11 circumferentially, when rotating parts 3 moves up, protuberance 11 outwards ejects gradually, makes protuberance 11 depart from the upper end of lower insulating cylinder 2, also namely achieves the separation of upper and lower insulating cylinder, the position that freely can adjust upper and lower insulating cylinder to change the entire length of insulating cylinder, to be applicable in the electric equipment products of different size; After length adjustment, rotating parts 3 moves down, and protuberance 11 is shunk inwards, until the lower end of protuberance 11 is supported in the upper end of lower insulating cylinder 2, fix the position of upper and lower insulating cylinder, insulating cylinder can normally use.
In technique scheme, described protuberance 11 outer surface is provided with external screw thread 111, the inner surface of described rotating parts 3 is provided with internal thread, described rotating parts 3 is threaded with described protuberance 11, rotating parts about 3 rotation can realize the separation of upper and lower insulating cylinder and fix, the position of the upper and lower insulating cylinder of convenient adjustment, changes the entire length of insulating cylinder.
In technique scheme, described protuberance about 11 offers some shrinkage hole bars 112, and described hole bar 112 runs through described protuberance 11 in a thickness direction, the surplus that hole bar 112 outwards moves inwards for providing protuberance 11, otherwise protuberance 11 easily ruptures.
In technique scheme, described upper insulating cylinder 1 is identical with described lower insulating cylinder 2 thickness, and axle center is consistent, and ensure that the consistency of the dielectric strength of insulating cylinder, avoid occurring dielectric strength weak place, entirety improves the dielectric strength of insulating cylinder.
From the above mentioned, telescopic insulating cylinder of the present utility model can conveniently stretch and fixing, according to the length of the adjusted size insulating cylinder self of electric equipment products to be applicable to this kind of electric equipment products; Good insulation preformance, improves the dielectric strength of the electric equipment products using this insulating cylinder; The highly versatile of this insulating cylinder, and cost is low.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in specification and execution mode utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
