Embodiment
With reference to the accompanying drawings and examples, embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to scope of the present utility model.
It is shown in Figure 2, a kind of retractor device being used in Pneumatic logistic pipeline, including sleeve pipe 1, one end of sleeve pipe 1 is
Has the flange arrangement of some screws, the inside of sleeve pipe 1 is provided with fixing pipe 2, and one end of fixing pipe 2 has tooth-shape structure.In sleeve pipe 1
Adjustable pipe 3 is additionally provided with, one end of adjustable pipe 3 has the tooth-shape structure identical tooth-shape structure with fixing pipe 2, the tooth of fixing pipe 2
The tooth-shape structure alternating expression of shape structure and adjustable pipe 3 coordinates to inserting.
Adjustable pipe 3 corresponding with fixing pipe 2 is provided with sleeve pipe 1, when transmission pipeline is due to expanding with heat and contract with cold or environmental change
And when occurring striction phenomenon, adjustable pipe 3 is subjected to displacement relative to sleeve pipe 1 and fixing pipe 2, so as to compensate transmission pipeline stroke
Change, it is ensured that the normal work of whole transmission pipeline.
Meanwhile, fixing pipe 2 and adjustable pipe 3 have identical tooth-shape structure, and its tooth-shape structure is closed to inserting, this dentation
Interim form staggeredly, when the adjustable pipe 3 is subjected to displacement change relative to sleeve pipe 1 and fixing pipe 2, also ensure that transmission pipeline
The object of middle conveying has the contact not less than 1/2 with the internal face of fixing pipe 2 and/or adjustable pipe 3, so as to prevent in transmission pipeline
The phenomenon that the object of conveying is blocked.
The extended line of the axis of fixing pipe 2 is overlapped with the axis of adjustable pipe 3.It can fully ensure that what is transmitted in logistics pipeline
Object passes through fixing pipe 2 and adjustable pipe 3.
Fixing pipe 2 is identical with the caliber of adjustable pipe 3.The tooth-shape structure of fixing pipe 2 and the tooth-shape structure of adjustable pipe 3 are same
Interdigitation on ring surface, enables fixing pipe 2 and adjustable pipe 3 to be preferably connected, and ensures that the object transmitted in logistics pipeline is suitable
Profit passes through.
The tooth-shape structure of fixing pipe 2 is rectangle rack.Rectangle rack is simple in construction, simultaneously, additionally it is possible to be prevented effectively from activity
Pipe 3 reverses the adverse effect to transmission pipeline relative to the radial direction of sleeve pipe 1 and fixing pipe 2.
When fixing pipe 2 and the alternating expression of adjustable pipe 3 are to inserting, the tooth-shape structure and the tooth-shape structure of adjustable pipe 3 of fixing pipe 2 are strict
Coincide, and retain certain gap, enable adjustable pipe 3 relative to fixing pipe 2 in the axial direction free movement and occur position
Move change.
Shown in Figure 3, the other end of fixing pipe 2 is provided with the method for some screws of tool coordinated with the flange arrangement of sleeve pipe 1
Blue structure, sleeve pipe 1 is sheathed on the outside of fixing pipe 2, and the flange arrangement and the flange arrangement of the one end of fixing pipe 2 of the one end of sleeve pipe 1
It is bolted to connection.
Static seal 4 is provided between sleeve pipe 1 and fixing pipe 2.Fully ensure that transmission pipeline is in sealing state, form sealing
Space, is not in the phenomenon of gas leakage, so as to ensure the normal work of Pneumatic logistic transport pipeline.
At least one dynamic seal 5a is provided between sleeve pipe 1 and adjustable pipe 3.When adjustable pipe 3 is moved relative to sleeve pipe 1 and send out
During raw relative displacement change, transmission pipeline is still in sealing state, is not in the phenomenon of gas leakage.
While the dynamic seal set between sleeve pipe 1 and adjustable pipe 3 ensures that transmission pipeline is in closed state, also to work
Spacing, guide effect is played in the dynamic motion of pipe 3 in axial direction, it is to avoid relative to sleeve pipe 1 and fixing pipe 2 position occurs for adjustable pipe 3
When moving change, occur radially to reverse, influence the normal work of transmission pipeline.
In one embodiment, two dynamic seals 5a and 5b, and two dynamic sealings are provided between sleeve pipe 1 and adjustable pipe 3
It is spaced apart between part.When adjustable pipe 3 is longer, or adjustable pipe 3 becomes relative to the displacement that sleeve pipe 1 and fixing pipe 2 occur
When changing larger, two or more dynamic seals are set, better seal and guide effect can be played.
Retractor device in Pneumatic logistic pipeline of the present utility model, when mounted, the tooth-shape structure of adjustable pipe 3 and fixation
The tooth-shape structure alternating expression of pipe 2 is remained with certain to inserting between the tooth-shape structure of adjustable pipe 3 and the tooth-shape structure of fixing pipe 2
Gap, enables adjustable pipe 3 to be subjected to displacement relative to the in axial direction free movement of fixing pipe 2, so as to compensate transmission pipeline
Because expand with heat and contract with cold or environmental change occur stroke change.
Static seal is set between sleeve pipe 1 and fixing pipe 2, dynamic seal is set between sleeve pipe 1 and adjustable pipe 3, is fully protected
The sealing of transmission pipeline is demonstrate,proved, makes transmission pipeline formation confined space, meanwhile, dynamic seal is set between sleeve pipe 1 and adjustable pipe 3
Spacing, guide effect also is played to the motion of adjustable pipe 3 in axial direction.
Finally, the present processes are only preferably embodiment, are not intended to limit protection domain of the present utility model.
It is all it is of the present utility model spirit and principle within, any modification, equivalent substitution and improvements made etc. should be included in this reality
Within new protection domain.
