Embodiment 1

[0028] Example 1, see figure 1 , figure 2 , image 3 and Figure 4, a manual-driven pipeline switching mechanism, including a valve opening structure 5, an inner column 1 and an outer ring 2 that is rotatably sleeved outside the inner column. An escape recess 21 is provided on the inner peripheral surface of the outer ring 2 . The avoidance pit 21 is a V-shaped pit. The outer ring is provided with a driving handle 23 for driving the outer ring to rotate. One end of the outer ring is provided with an end plate 22 to form a barrel with one end closed. Built inside the barrel. The end face of the inner column 1 is provided with a central hole 11 and a number of peripheral holes 12 surrounding the central hole. Each peripheral hole communicates with the central hole through a communication hole 13 . The communication hole is a straight line structure. The communication hole is provided with an extension section 14 penetrating the peripheral surface of the inner column. ...

Embodiment 2

[0030] Embodiment two, the difference with embodiment one is:

[0031] see Figure 5 and Image 6 , the outer end of the plug is provided with a positioning hole 31 . The avoidance pit is provided with a plug installation through hole 32 penetrating the outer ring in the radial direction of the outer ring and aligned with the positioning hole when the outer end of the plug is located in the avoidance pit. A locating pin 3 and a locating pin driving spring 33 for driving the locating pin to be inserted into the locating hole are arranged in the bolt mounting through hole. When one end of the positioning pin is inserted into the positioning hole, the other end extends out of the outer ring.

[0032] When the outer ring needs to be rotated, grab the part of the positioning pin exposed outside the outer ring and pull out the positioning pin from the positioning hole, and then turn the outer ring, when the outer ring is rotated to close to the plug attachment that needs to be al...

Embodiment 3

[0033] Embodiment three, the difference with embodiment two is:

[0034] see Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 , the central hole 11 is also provided with a connecting joint 9 . The connecting joint includes a connecting pipe head 99, an internally threaded pipe section 91 disposed in the outer end of the central hole, and a positioning step 92 located at the inner end of the internally threaded pipe section. The outer end of the internally threaded pipe section is provided with a large diameter section to form a first sealing step 93 . One end of the connecting pipe head 99 is provided with an external thread pipe section 94 . A second sealing step 95 is formed between the externally threaded pipe section and the connecting pipe head. The connecting pipe head 99 can be inserted into the large diameter section. The externally threaded pipe section is threadedly connected with an externally threaded pipe section 96 sleeved on the externally t...

Abstract

The invention relates to a manual drive type pipeline switching mechanism. The manual drive type pipeline switching mechanism comprises a valve opening structure, an inner column and an outer ring rotationally arranged outside the inner column in a sleeving manner. The outer ring is provided with a drive handle. An avoiding pit is formed in the inner circumference face of the outer ring. The end face of the inner column is provided with a center hole and a plurality of periphery holes surrounding the periphery of the center hole. Each periphery hole communicates with the center hole through acommunication hole. Each communication hole is provided with an extension section penetrating through the circumference face of the inner column, wherein the extension section is of a linear structure, and a plug is arranged in the communication hole in a sealed and movable penetration manner. For all the plugs, the outer end of only one plug can be located in the avoiding pit at one time. When the outer end of one plug is located in the avoiding pit, the sealing function on the corresponding communication hole through the plug gets lost under the action of the valve opening structure. When the outer ends of the plugs are staggered from the avoiding pits, the plugs are sealed and closed in the communication holes under the extrusion action of the outer ring. The manual drive type pipelineswitching mechanism is used for achieving control over communication of multiple pipelines and one pipeline.

Description

technical field [0001] The invention relates to a mechanical structure on traditional Chinese medicine production equipment, in particular to a manually driven pipeline switching mechanism. Background technique [0002] In the automatic production equipment of traditional Chinese medicine, a variety of different liquids need to be input into the same infusion main pipe through different pipelines and then transported to the destination. Only one of the pipes can be connected to the infusion main pipe at the same time. The existing implementation of the above connection is achieved through a solenoid valve. In addition, the existing method for sealing and detachable connection of two pipe bodies is to set threaded heads on the ends of the two pipe bodies, and then wrap raw tape on the threaded heads and then threadedly connect the two ends of the internally threaded pipe heads. The detachable connection is realized on the upper part, and the sealing is realized by the defor...
