Description
Technical field
A kind of screw thread switching device field is the utility model is related to, one kind firmly installs easy-to-dismount screw thread switching smoke pipe
Device.
Background technology
China's industrial boom in recent years, it is increasing to the demand of screw thread switching device, it is desirable to also come it is higher, but
Exploitation of the China to screw thread switching device falls behind relatively；Interim switching smoke pipe is needed to be discharged fume when unit is discharged fume, for the ease of
Dismounting, in most cases, smoke pipe is attached by screw thread and unit exhaust opening, but is simply threaded in unit
The loosening of threaded connection can be caused during operation due to the vibration of unit, causes coming off for smoke pipe；The utility model proposes one
Kind firmly installs easy-to-dismount screw thread switching smoke pipe device, is expected to preferably solve these problems, the device is put down in internal thread
Increase clamp nut after row active joint and spring washer fasten to active joint, that is, can guarantee that the facility of smoke pipe dismounting,
The situation that and can prevents smoke pipe and come off because of vibration occurs.
The content of the invention
The technical problem that the utility model solves is to provide one kind and firmly installs easy-to-dismount screw thread switching smoke pipe device,
The device is provided with clamp nut after internal thread parallel activity joint and spring washer fastens to active joint, Ji Nengbao
The facility of smoke pipe dismounting is demonstrate,proved, the situation that and can prevents smoke pipe and come off because of vibration occurs.
A kind of technical scheme is used to solve above-mentioned technical problem the utility model:One kind firmly installs easy-to-dismount spiral shell
Line switching smoke pipe device, mainly includes internal thread parallel activity joint, external screw thread smoke pipe, clamp nut and spring washer, unit
External screw thread smoke pipe；It is characterized in that：Clamp nut is fixed with the left of external screw thread smoke pipe, spring washer is lined with the left of clamp nut,
Internal thread parallel activity joint is installed on the left of spring washer, is fixed on by neck on unit external screw thread smoke pipe.
The beneficial effects of the utility model are：The device adds clamp nut and bullet after internal thread parallel activity joint
Spring packing ring, i.e. internal threads parallel activity joint serve fastening effect, and do not influence the fast assembling-disassembling of smoke pipe.
Brief description of the drawings
Schematic device when Fig. 1 is utility model works state.
It is attached：The mark of each part is as follows in Fig. 1：1 internal thread parallel activity joint, 2 spring washers, 3 clamp nuts, 4
External screw thread smoke pipe, 5, unit external screw thread smoke pipe.
Embodiment
Example of the present utility model is described in further detail below in conjunction with brief description of the drawings, but this example is not used to limit
The utility model processed, it is every to use similar installation of the present utility model and its similar change, guarantor of the present utility model all should be included in
Protect scope.
Referring to Fig. 1, the utility model embodiment includes：One kind firmly installs easy-to-dismount screw thread switching smoke pipe dress
Put, mainly include internal thread parallel activity joint 1, external screw thread smoke pipe 4, clamp nut 3 and spring washer 2, unit external screw thread cigarette
Pipe 5；It is characterized in that：The left side of external screw thread smoke pipe 4 is fixed with clamp nut 3, and the left side of clamp nut 3 is lined with spring washer 2, spring
The left side of packing ring 2 is provided with internal thread parallel activity joint 1, is fixed on by neck on unit external screw thread smoke pipe 5.
Operation principle of the present utility model：After the parallel joint 1 of internal thread is tightened, then clamp nut 3 is tightened, while by
Screw thread parallel activity joint 1 fastens, and effectively prevents internal thread active joint 1 from causing coming off for smoke pipe because unit vibration loosens,
And do not influence the fast assembling-disassembling of whole smoke pipe.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or other phases are used in indirectly
The technical field of pass, similarly it is included in the utility model patent protection domain.
