Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

As Fig. 3～shown in Figure 5, a kind of filter of the utility model flies bar structure 100, comprises flying bar 10 and flying pole socket 20, flies bar 10 and is fixed in and flies pole socket 20, and this flies pole socket 20 and is fixed in cavity body filter.

Fly bar 10 and comprise that first coupling part 11, second coupling part 12 and connecting portion 13, the first coupling parts 11 between first coupling part 11 and second coupling part 12 and second coupling part 12 offer for the coupling adjustment hole 14 of regulating the coupling amount.Preferably, fly bar 10 in the form of sheets, first coupling part 11, second coupling part 12 are extended by connecting portion 13 bendings and form, and in the manufacture process that flies bar 10, flying bar 10 can be bent to form by the rectangular laminated structure of two ends perforate, and weight is lighter, also is convenient to simultaneously make.

The utility model is by offering coupling adjustment hole 14 at the coupling part that flies bar 10, realization flies the change of the coupling amount of bar, in the little product of needs coupling amount, it is bigger that this coupling adjustment hole 14 can be offered, in the little product of needs coupling amount, it is less that this coupling adjustment hole 14 can be offered, thereby flying bar 10 can arrange different coupling adjustment holes 14 and get final product according to different coupling demands, and do not need to change disk track and the length that flies bar, less demanding to the production mould diversity that flies bar, the manufacture of perforate is also comparatively simple, saves production cost.Whereby, the present invention is simple in structure, and is simple in structure, is convenient to manufacture, and reduced production cost.

As shown in Figure 5, flying pole socket 20 is provided with three and laterally runs through groove 21, flying bar is installed on and laterally runs through in the groove 21, certainly the number that laterally runs through groove 21 can arrange one or more, it is to adjust to fly bar 10 in the relative altitude of cavity that a plurality of purposes that laterally run through groove 21 are set, for example in the bigger situation of coupling amount demand, what fly that the coupling part of bar 10 may arrange is longer, for guaranteeing that coupling part does not exceed the cavity of cavity body filter, can be arranged on and fly pole socket 20 laterally running through in the groove of below flying bar 10; In some cavity body filter, resonant rod is installed on the boss of cavity body filter bottom, and the height of resonant rod is higher, therefore can be arranged on and flies pole socket 20 laterally running through in the groove by top flying bar 10 in this case; Simultaneously, require under the big situation two or more bars 10 that fly to be installed also in the coupling amount.Thereby a plurality of grooves 21 that laterally run through are set tackle various occasions, improved the versatility of product.

As shown in Figure 5, fly pole socket 20 and comprise first pedestal 22 and second pedestal 23 that removably connects, first pedestal, 22 axial directions are provided with boss 221, second pedestal, 23 axial directions are provided with groove 231, the first pedestals 22 of boss 221 corresponding engagings and interconnect by boss 221 and cooperating of groove 231 with second pedestal 23.The pole socket 20 that flies of this minute body structure is convenient to more install and is flown bar 10, having under a plurality of situations that laterally run through groove 21, is convenient to change the installation site that flies bar 10.Laterally running through groove 21 is spliced with second draw-in groove 232 that is positioned at second pedestal 23 by first draw-in groove 222 that is positioned at first pedestal 22.

As shown in Figure 5, the connecting portion 13 that flies bar 10 also comprises the 3rd draw-in groove 131 that is positioned at the connecting portion both sides, fly bar 10 and be fastened in by the 3rd draw-in groove 131 and fly laterally the running through in the groove 21 of pole socket 20, and the length of the 3rd draw-in groove 131 equates with the lateral length that flies pole socket 20.

Fly pole socket 20 and comprise also for flying pole socket 20 and be fixed in position limiting structure on the muscle of filter that this position limiting structure is preferably the 4th draw-in groove 24 that is arranged at first pedestal 22 and second pedestal 23 respectively.When installation flies bar, at first will fly bar 10 card as first pedestal 22 first draw-in groove 222 or and second draw-in groove 232 of second pedestal 23 in, with

first pedestal

22 and 23 splicings of second pedestal, will fly bar structure 100 snaps in filter 100 by the 4th draw-in groove 24 muscle at last again.

The utility model provides a kind of cavity body filter, and this cavity body filter comprises the above-mentioned bar structure 100 that flies.

In sum, the bar that flies of the present utility model comprises first coupling part, second coupling part and the connecting portion between described first coupling part and described second coupling part, and described first coupling part and described second coupling part offer for the coupling adjustment hole of regulating the coupling amount.By offering the coupling adjustment hole at the coupling part that flies bar, realization flies the change of the coupling amount of bar, in the little product of needs coupling amount, it is bigger that this coupling aperture can be offered, in the little product of needs coupling amount, it is less that this coupling aperture can be offered, can different coupling apertures be set according to different coupling demands and get final product thereby fly bar, and not need to change disk track and the length that flies bar, less demanding to the production mould diversity that flies bar, the manufacture of perforate is also comparatively simple, saves production cost.Whereby, the present invention is simple in structure, and is simple in structure, is convenient to manufacture, and reduced production cost.
