In order to realize above purpose, a kind of filter flying pole socket that the utility model provides with fly the bar piece fixed structure, comprise flying the bar sheet, flying pole socket and cavity, be provided with in the described cavity be used to the muscle of cutting apart chamber, have mounting groove on the muscle of described cavity, the described pole socket that flies is fixed in the mounting groove; The described pole socket that flies is stepped, flies the top width W1 of pole socket greater than bottom width W2, and the middle part that flies pole socket has the location hole that matches with screw; The described end face that flies pole socket also is provided with and a plurality of guide vane end stops that fly the bar sheet and match, fly the bar sheet and be located at the end face that flies pole socket, the two sides that fly the bar sheet are spacing by being located at the guide vane end stop that flies the pole socket end face, the described end face that flies pole socket is provided with the upper limit boss around the location hole peritreme, fly bar sheet middle part and be provided with the installing hole that matches with the upper limit boss; Describedly fly the bar sheet and fly pole socket and be fixed on the muscle by screw and insulation spacer.

As preferred version of the present utility model: the below of mounting groove has the first narrow stopper slot of Width mounting groove, flies the wider top of pole socket and is located in the mounting groove; The described narrower bottom of pole socket that flies is located in the first stopper slot and is matched with it.

As further preferred version of the present utility model: the described bottom surface that flies pole socket is provided with the lower limit boss around the location hole peritreme, the below of described the first stopper slot also has the second narrow stopper slot of Width the first stopper slot, and described lower limit boss is located in the second stopper slot and with it and is matched.

As further preferred version of the present utility model: also be provided with on the described guide vane end stop medial surface and prevent from flying the buckle that the bar sheet is upturned.

As preferred version of the present utility model: the described pole socket that flies is prepared by the PEI material.

The beneficial effects of the utility model: one, be fixed on the structure that flies on the pole socket owing to adopt the screw fit insulation spacer will fly the bar sheet, it is better to make its tightness compare interference fit; Its two owing to adopt screw fastening to fly the bar sheet and fly pole socket, therefore fly the expansion that pole socket occurs and can not have influence on the position that flies the bar sheet under higher temperature, further increased its tightness.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment: as shown in Figure 1, the designed a kind of filter flying pole socket of the utility model with fly the bar piece fixed structure, comprise fly bar sheet 1, fly pole socket 2, cavity 5, insulation spacer 3 and screw 4.Wherein, be provided with in the cavity 5 be used to the muscle 5.1 of cutting apart chamber, have mounting groove 6 on the muscle 5.1, fly pole socket 2 and be fixed in the mounting groove 6.The below of mounting groove 6 has the first narrow stopper slot 7a of Width mounting groove 6.Fly pole socket 2 by PEI material preparation and stepped, fly the top width W1 of pole socket 2 greater than bottom width W2, fly pole socket 2 wider tops and be located in the mounting groove 6; The described pole socket 2 narrower bottoms that fly are located in the first stopper slot 7a and are matched with it.The described bottom surface that flies pole socket 2 is provided with lower limit boss 8b around location hole 2.1 peritremes, the below of described the first stopper slot 7a also has the second narrow stopper slot 7b of Width the first stopper slot 7a, and described lower limit boss 8b is located at the interior 7b of the second stopper slot and matches with it.

The middle part that flies pole socket 2 has the location hole 2.1 that matches with screw 4; The end face that flies pole socket 2 also is provided with and a plurality of guide vane end stops 9 that fly bar sheet 1 and match, and also is provided with on guide vane end stop 9 medial surfaces and prevents from flying the buckle 9.1 that bar sheet 1 is upturned.Fly bar sheet 1 and be located at the end face that flies pole socket 2, the two sides that fly bar sheet 1 are spacing by being located at the guide vane end stop 9 that flies pole socket 2 end faces.The end face that flies pole socket 2 is provided with upper limit boss 8a around location hole 2.1 peritremes, fly bar sheet 1 middle part and be provided with the installing hole 1.1 that matches with upper limit boss 8a; Fly bar sheet 1 and fly pole socket 2 to be fixed on the muscle 5.1 by screw 4 and insulation spacer 3.

Upper limit boss 8a, guide vane end stop 9, buckle 9.1, screw 4 and insulation spacer 3 cooperate in the utility model, can prevent from flying bar sheet 1 and move.Lower limit boss 8b cooperates with the bottom that flies pole socket 2, can prevent from flying pole socket 2 and move.They jointly make this filter flying pole socket and fly the bar piece fixed structure has had good tightness.

Have the shaft bar that flies of PTFE material preparation now, because thermal coefficient of expansion is 10 ~ 20 times of metal, therefore being heated causes deformation easily, causes and flies the fastening inefficacy of bar in it.Preparation flies pole socket 2 employed PEI materials and then has very strong high-temperature stability and electrical insulating property in the utility model, thereby filter flies pole socket 2 and do not have too large deformation when working under hot environment, and tightness is good; Simultaneously, be to be fixed on by screw 4 and insulation spacer 3 to fly on the pole socket 2 but not be located to fly in the shaft bar owing to fly bar sheet 1, therefore further reduced to fly pole socket 2 impact that deformation causes when high temperature, further improved tightness.

The above only is preferred embodiment of the present utility model, is not the utility model structure is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment does.
