And, existing metal bar (metal probe) is to be generally fixed on connecting portion, connecting portion is directly welded on probe cassette or probe socket, but it adopts the mode of welding, take off very trouble, and metal bar generally cannot be directly fixed on equipment, its need to be on equipment mounting fixing parts so that metal bar fix.
And be fixedly connected with whole probe in the time that connecting portion wherein damages and just need to change, and metal bar or operable in fact has so just produced unnecessary waste, increase maintain and replace cost.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of flanged (FLGD) dust metal bar is provided, it can be fixedly connected on equipment by joint flange, it removes and installs very convenient, and on its fixed bar, also have external thread to be screwed onto on probe cassette to facilitate, improve its Installation Flexibility, in the time that probe cassette damages, fixed bar unloads and can reuse.Meanwhile, Teflon material layer is coated on metal bar, has high temperature resistant, high pressure resistant, corrosion-resistant, sealing and the stable feature of translation data.
The scheme that the utility model solve the technical problem is:
A kind of flanged (FLGD) dust metal bar, comprise metal bar, described metal bar is fixed in coupling sleeve, and the lower end of coupling sleeve is stretched out in the lower end of metal bar, the part that metal bar stretches out the lower end of coupling sleeve is induction part, is at least coated with Teflon material layer on induction part surface;
The top of fixed bar forms external thread, the middle part outer wall of fixed bar forms joint flange, coupling sleeve sleeve holding are in the central through hole of fixed bar, the top of coupling sleeve is stretched out fixed bar top end and is formed stiff end, the diameter of stiff end is greater than the diameter of coupling sleeve, the bottom end face of stiff end is pressed against on the top end face of fixed bar, and the bottom of fixed bar is stretched out in the bottom of coupling sleeve.
On the middle part outer wall of described stiff end, form the second annular groove.
Described Teflon material layer is sprayed on whole metal bar surface.
The top of described stiff end is bolted with contiguous block, and contiguous block forms through hole, and through hole is just to the connecting screw hole forming on the top end face of metal bar.
Described fixed bar is metal material, and described coupling sleeve is Teflon material.
On described joint flange, form multiple connecting through holes.
Outstanding effect of the present utility model is:
1, compared with prior art, it can be connected on equipment by joint flange, and it removes and installs very convenient, and on its fixed bar, also have external thread to be screwed onto on probe cassette to facilitate, improve its Installation Flexibility, in the time that probe cassette damages, fixed bar unloads and can reuse.
2, Teflon material layer is coated on metal bar, makes it have high temperature resistant, high pressure resistant, corrosion-resistant, sealing and the stable feature of translation data.
3, its coupling sleeve is Teflon material; it can play second layer protection to metal bar; simultaneously the top of its coupling sleeve is stretched out on the middle part outer wall of the stiff end that fixed bar top end forms and is formed the second annular groove; in the second annular groove, can be fixed on probe cassette by contiguous block, guarantee that metal bar can better be fixed in probe cassette.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model is arranged on the structural representation in probe cassette.
Embodiment:
Embodiment, see as shown in Fig. 1 to 2, a kind of flanged (FLGD) dust metal bar, comprise metal bar 2, described metal bar 2 is fixed in coupling sleeve 3, the lower end of coupling sleeve 3 is stretched out in the lower end of metal bar 2, and the part that metal bar 2 stretches out the lower end of coupling sleeve 3 is induction part, is at least coated with Teflon material layer 4 on induction part surface;
The top of fixed bar 5 forms external thread, the middle part outer wall of fixed bar 5 forms joint flange 51, coupling sleeve 3 sleeves holding are in the central through hole 52 of fixed bar 5, the top of coupling sleeve 3 is stretched out fixed bar 5 top ends and is formed stiff end 31, the diameter of stiff end 31 is greater than the diameter of coupling sleeve 3, the bottom end face of stiff end 31 is pressed against on the top end face of fixed bar 5, and the bottom of fixed bar 5 is stretched out in the bottom of coupling sleeve 3.
