Specific embodiment
As shown in Figure 1, the transmission bar assembly includes two groups of drive rods, multiple check valve (not shown) and multiple fixing cards
Piece 200, every group of drive rod is connected in sequence by multiple bodies of rod 100, and for the transmission of mud, check valve setting is adjacent at two
The junction of the body of rod 100, to reduce the time of boosting, fixed card 200 is for fixing two groups of drive rods, thus two groups of biographies of control
Spacing between lever, prevention transmission rod bending or sagging, and prevent drive rod and pipeline from the problems such as rubbing or winding occurs.
As shown in Figures 2 to 4, two adjacent bodies of rod 100 can be connected through a screw thread, and specifically, the body of rod 100 includes first
End and second end, the first end of the body of rod 100 are located at one end on 100 length direction of the body of rod, and the second end of the body of rod 100 is located at the body of rod
The other end on 100 length directions, wherein be provided with slurry channel 110 on the body of rod 100, slurry channel 110 is from the body of rod 100
It is extended on the end face of one end on the end face 150 of 100 second end of the body of rod, i.e., the body of rod 100 is hollow structure, it is preferable that slurry channel
110 can be located on the center of the body of rod 100, in addition, the first end of the body of rod 100 is provided with external screw thread 120, the second end of the body of rod 100
It is provided with internal screw thread 130, therefore, is cooperated between two adjacent bodies of rod 100 by internal screw thread 130 and external screw thread 120, to realize
It is threadedly coupled, in this way it can be ensured that the body of rod can be in rotation suitable, counterclockwise, to load and unload, and can advance with after with the body of rod
It moves back, and will not slide back and forth and fixed card is caused to be piled up at one.It will be appreciated by persons skilled in the art that when two bars
After body 100 connects, the slurry channel 110 of the two is communicated.
In other embodiments, two adjacent bodies of rod 100 can be snapping.
As shown in Figure 1 and Figure 5, it is provided with first sets of holes 210 and two the second sets of holes 220 in fixed card 200, two
A second sets of holes 220 are located at the two sides of the first sets of holes 210, wherein and the first sets of holes 210 are socketed in the outside of pipeline 300, the
Two sets of holes 220 are socketed in the outside of the body of rod 100.As depicted in figs. 1 and 2, the outside of the body of rod 100 is provided with step 140, the step
140 is adjacent with the first end of the body of rod 100, and fixed card 200 can be located at 100 second end end face 150 of the body of rod and connect with its second end
Between step 140 on extension bar body 100, in this way, fixed card 200 is fixed on the body of rod 100, without sliding phenomenon occurs,
