Figure 1 As shown, a scale or corresponding reading may be set on the surface of the upper shell 201 and inside the observation window 207, so as to facilitate understanding of the specific flow in the through port 105;

[0028] A movable rod 203 is slidably connected to the inner wall of the upper shell 201 and located below the knob 205. One end of the movable rod 203 passes through the upper shell 201, and the other end of the movable rod 203 is close to the gear 202 and fixedly connected to a clamping block 208. The outer side of the clamping block 208 is in movable contact with the surface of the gear 202. A spring 204 is fixedly connected to the middle of the movable rod 203, and the other end of the spring 204 is fixedly connected to the inner wall of the upper shell 201. Figure 3 As shown, the block 208 is made of rubber. The block 208 increases the friction between the movable rod 203 and the surface of the gear 202. Driven by the spring 204, the block 208 presses against the gear 202 to prevent its rotation.

[0029] The connecting mechanism 1 includes a lower shell 101, the top middle of the lower shell 101 is fixedly installed with the upper shell 201, and the middle of the front and back of the lower shell 101 are rotatably connected with a connecting pipe 102, and the inner part of the connecting pipe 102 is provided with a thread, such as Figure 1 As shown, by rotating the connecting pipe 102 and matching the inner thread, the lower housing 101 can be conveniently installed between the pipelines on both sides;

[0030] A limit opening 106 is provided at the top of the lower shell 101 and below the upper shell 201, a through opening 105 is provided in the middle of the inner wall of the lower shell 101, a slide groove 104 is provided on the surface of the lower shell 101 and outside the through opening 105, and a rotation groove 103 is provided on the surface of the lower shell 101 and outside the slide groove 104. Figure 4 As shown, the fluid passes through the through port 105;

[0031] The rotating groove 103 is hexagonal in shape as a whole. Each inner wall of the rotating groove 103 is slidably connected with a baffle 107, and one end of the surface of all the baffles 107 is fixedly connected with an extrusion shaft 108. The sides of adjacent baffles 107 are slidably connected to each other. The inner wall of the rotating groove 103 is slidably connected with a rotating plate 109. The surface of the rotating plate 109 and the outer side of each extrusion shaft 108 are provided with an extrusion groove 110. The inner side of the extrusion groove 110 is slidably connected to the extrusion shaft 108. Figure 3-Figure 5 As shown, the length direction of the extrusion groove 110 is staggered with the center of the through hole, so when the rotating plate 109 rotates, it can push the inner extrusion shaft 108, driving the baffle 107 and the sliding groove 104 to move;

Figure 3-Figure 4 As shown, the limiting opening 106 limits the moving distance of the annular rack 111 to prevent the annular rack 111 from disengaging from the gear 202 .

[0033] The working principle of this utility model:

[0034] When the device is in use, the connecting tube 102 is rotated and installed between the pipelines on both sides in conjunction with the internal threads. When adjusting the flow rate of the fluid passing through the through port 105, the movable rod 203 is pressed to separate the block 208 from the surface of the gear 202. At this time, the rotation of the gear 202 is no longer hindered, and the gear 202 is driven to rotate by rotating the knob 205. The gear 202 pushes the lower annular rack 111 to drive the rotating plate 109 to rotate inside the rotating groove 103. During this period, the extrusion groove 110 pushes the extrusion shaft 108 and drives the baffle 107 to move on the inner wall of the slide groove 104, so that the size of the gap between each baffle 107 and the through port changes, and the actual flow rate in the through port changes accordingly. When it is necessary to fix the position of each baffle 107, the movable rod 203 is released, and the spring 204 releases the elastic potential energy to push the movable rod 203 to reset, and then the block 208 is tightly pressed against the surface side of the gear 202 to limit its rotation, and the baffle 107 cannot move due to the movement of the rotating plate 109.

[0035] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
