Description
Technical field
The present invention relates in Chinese medicine production equipment mechanical structure more particularly to a kind of manual actuation formula pipeline switching machine
Structure.
Background technique
In equipment for automatic production, need to input a variety of different liquid by different pipelines same defeated
Destination is then delivered in liquid general pipeline.Synchronization is merely able to make the wherein same infusion general pipeline connection in a root canal road.Existing reality
It is now above to be connected as realizing by solenoid valve.In addition existing the mode being detachably connected is sealed to two tube bodies to be
Thread head is set on the end of two tube bodies, upper unsintered tape rear thread is then wound on thread head and is connected to internal screw thread tube head
Both ends on realize and be detachably connected, sealing is realized by the deformation of unsintered tape.The connection type is due to thread head and interior spiral shell
The screw thread of junction can be made exposed when generating variation between the length of line tube head, screw thread exposed not only aesthetics difference and also due to
Planarization difference is easy dust accumulation and does not allow easy to clean, and is sealed by unsintered tape, inconvenience when sealing；If not two
Thread head is set on a pipeline but two pipelines are welded together and are connected and sealed, the exposed of screw thread can be prevented, but
It is to weld, it is inconvenient when being dismantled.
Summary of the invention
The first purpose of this invention is intended to provide a kind of manual actuation formula pipeline switching mechanism, for realizing more root canal roads
The connection of the same pipeline controls.
Second object of the present invention is intended to provide one kind and sets that junction screw thread can either be avoided exposed and can be realized can
The manual actuation formula pipeline switching mechanism of the jointing of dismantling connection, for solve existing jointing to two root canal roads into
The problem for being detachably connected and avoiding screw thread exposed can not be taken into account when row connection.
The above technical problem is solved through the following technical scheme: a kind of manual actuation formula pipeline switching mechanism, special
Sign is, is set in the outer ring outside inner prop including valve opening structure, inner prop and rotation, the outer ring is equipped with driving outer ring rotating
Driving handle, the inner peripheral surface of the outer ring are equipped with evacuation pit, and the end face of the inner prop is equipped with centre bore and several surround

Driving will not lead to the problem of fatigue failure for opening compared with above-mentioned spring.
Preferably, the drive block is roller structure, the drive block is contacted by circumferential surface with the jacking block.It can drop
Low abrasion.
Preferably, the intercommunicating pore is linear structure, the intercommunicating pore and extended segment are located along the same line.Production side
Just.
Preferably, the centre bore is connected with jointing, the jointing includes connecting pipe head, the centre bore
Outer end in be equipped with internal screw thread pipeline section and the positioning step positioned at internal screw thread pipeline section inner end, one end of the connecting pipe head is equipped with outer
Screw thread pipeline section is threaded with the internal and external threads pipeline section being set on external screw thread pipeline section on the external screw thread pipeline section, described inside and outside
Screw thread pipeline section is threaded in the internal screw thread pipeline section and connecting pipe head and centre bore links together, the riffled tube
Section is sealed connected together with the external screw thread pipeline section by seal assembly, and the external screw thread pipeline section and internal and external threads pipeline section are complete
It is accommodated in the internal screw thread pipeline section, one end of the separate connecting pipe head of the external screw thread pipeline section and internal and external threads pipeline section are close to even
It is linked together between one end of pipe joint by automatic mounting mechanism.The method when present invention is attached general pipeline is, always
Pipe is welded on the other end of connecting pipe head.The technical program can pass through the overlapping between internal and external threads pipe and external screw thread pipeline section
The distance between free end and the connecting pipe head end plate for feeding to change internal and external threads section, so that external screw thread pipeline section is all located at import
It is interior and avoid screw thread exposed.The centre bore of internal screw thread pipeline section with different length can be matched with same connecting pipe head,
Versatility is good.Realize second goal of the invention.
Preferably, the outer end of the internal screw thread pipeline section is equipped with major diameter section and forms the first sealed step, the external screw thread
The second sealed step is formed between pipeline section and connecting pipe head, the seal assembly includes being arranged in second sealed step
Along the annular groove of connecting pipe head circumferentially extending, the ring packing air bag in annular groove and it is arranged in first sealed step
Along the sealing ring of the circumferentially extending of internal screw thread pipeline section, the sealing ring, which can be worn, squeezes the ring packing in the annular groove
Air bag and make the ring packing air bag deform and be sealed connected together the first sealed step and the second sealed step, institute
Connecting pipe head is stated to be inserted into the major diameter section.A kind of specific technical solution of seal assembly is provided, the seal assembly is close
It is good to seal effect, and can be achieved at the same time between male end of a pipe and internal screw thread pipeline section and internal and external threads screw thread pipeline section and interior
Sealing between screw thread pipeline section.It is existing inconvenient when being sealed by unsintered tape to solve the problems, such as.
If the annular is close preferably, the sealing ring, which is equipped with arterial highway, is sequentially sleeved at ring packing teeth together
Tooth is sealed along the circumferentially extending of internal screw thread pipeline section.Sealing effect can be further increased.
