[0019] See also Figures 1-12The present invention provides a technical solution: an adjustable post-casting strip flow-blocking device, comprising a first side rod 1, a second side rod 2, a flow-blocking mechanism and a docking mechanism, wherein the upper and lower ends of the first side rod 1 and the second side rod 2 are fixedly connected with a top rod 3 and a bottom rod 4 respectively, and the flow-blocking mechanism includes a flow-blocking piece 5 installed between the first side rod 1 and the second side rod 2, and the side surfaces of the first side rod 1 and the second side rod 2 are slidably connected with an adjusting rod 6, and the flow-blocking mechanism can adjust the height of the flow-blocking piece 5 through the adjusting rod 6, so that the position where flow blocking is required presents a double-layer flow blocking effect, and the flow-blocking piece 5 at the position where flow blocking is not required will not be used, and the docking mechanism is installed on the adjusting rod 6, for docking multiple groups of first side rods 1 with the second side rod 2, and limiting the position after the adjustment of the first group of adjusting rods 6 is completed, so that when the subsequent adjusting rods 6 are adjusted, they can quickly reach the limit position, thereby improving the efficiency of docking and adjustment.

[0020] The flow-blocking mechanism also includes two sets of guide shafts 7 fixedly installed between the first side rod 1 and the second side rod 2. The sides of the first side rod 1 and the second side rod 2 are respectively provided with guide grooves 8.

[0021] The flow blocking member 5 includes a rubber strip 10 fixedly mounted on the bottom surface of both ends of the adjusting rod 6.

The side of the galvanized iron mesh layer 11 is fixedly connected to a nylon filter cloth layer 12 through Velcro. The side of the nylon filter cloth layer 12 is fixedly connected to a reinforcement layer 13 through Velcro. A plurality of groups of transversely arranged reinforcement ribs 14 are evenly and fixedly connected in the reinforcement layer 13. The two ends of the reinforcement rib 14 are respectively fixedly connected to the rubber strips 10 on both sides. The outer wall of the bottom end of the galvanized iron mesh layer 11 can slide and fit with the top surface of the bottom rod 4.

[0022] The docking mechanism includes two groups of control rods 16 that are slidably connected to the adjusting rod 6 in the horizontal direction. A sliding groove 17 is provided on the adjusting rod 6. The sides of the first side rod 1 and the second side rod 2 are respectively slidably connected with sliding rods 18 in the horizontal direction. The sliding rod 18 passes through the control rod 16 and is slidably connected to the inner wall of the control rod 16 in the vertical direction. The sliding rod 18 passes through the sliding groove 17. A control part 19 for controlling the sliding state of the control rod 16 is provided on the adjusting rod 6. The docking mechanism also includes a limit rod 38 fixedly mounted on the side of the first side rod 1. A limit groove 39 is provided on the side of the second side rod 2. The limit rod 38 can be plugged into the inner wall of the limit groove 39 in the vertical direction.

[0023] The control member 19 includes a device box 20 fixedly mounted on the control rod 16, and a first spring block 21 is provided in the device box 20. The side surfaces of the first side rod 1 and the second side rod 2 are respectively provided with multiple groups of scale grooves 22. The tip of the first spring block 21 can be engaged with the scale grooves 22. The adjusting rod 6 is provided with a driving member 23 for driving the control rod 16 to slide, and the sliding rod 18 is provided with a limiting member 24 for limiting one end of the flow blocking member 5.

[0024] The storage component 9 includes end plates 25 fixedly mounted on the side surfaces of both ends of the push rod 3, a fixed shaft 26 is fixedly connected between the two groups of end plates 25, an outer wall of the fixed shaft 26 is fixedly connected to a clockwork spring 27, a winding shaft 28 is fixedly connected to the clockwork spring 27, one end of the rubber strip 10 is fixedly connected to the outer wall of the winding shaft 28, both ends of the winding shaft 28 are respectively fixedly connected to a driving tube 29, the driving tube 29 is coaxially connected to the outer wall of the fixed shaft 26 for rotation, and a box cover 41 is fixedly connected to the side of the push rod 3.

[0025] The limiting member 24 includes a sliding frame 30 fixedly mounted on the top of the sliding rod 18, and a second spring block 31 is provided in the sliding frame 30. The outer wall of the driving tube 29 is evenly provided with multiple groups of oblique tooth grooves 32, and the tip of the second spring block 31 can be unidirectionally engaged with the oblique tooth groove 32 to limit the position.

[0026] The driving member 23 includes a rotating buckle 34 fixedly mounted on the side of the control rod 16, a handle 35 is provided on the side of the adjusting rod 6, and a connecting buckle 36 is fixedly connected to the side of the handle 35. Two groups of connecting rods 37 are rotatably connected to the connecting buckle 36, and the two groups of connecting rods 37 are rotatably connected to the rotating buckles 34 on both sides respectively. A magnetic block 40 that can be magnetically attracted to the connecting buckle 36 is fixedly connected to the side of the adjusting rod 6.

[0027] In this embodiment, after the first set of flow-blocking devices is fixed, the handle 35 is pulled upward, and the control rod 16 will slide upward along the sliding rod 18. At the same time, the adjusting rod 6 will drive the rubber strip 10, the galvanized iron mesh layer 11, the nylon filter cloth layer 12 and one end of the reinforcement layer 13 at the bottom to move upward together. The flow-blocking member 5 is output from the winding shaft 28, and the clockwork spring 27 is compressed. Through the guiding action of the guide groove 8 and the guide shaft 7, the flow-blocking member 5 is bent upward at the bottom position, ensuring that the outermost side is the galvanized iron mesh. Layer 11, the middle is the nylon filter cloth layer 12, the innermost is the reinforcement layer 13, and the multiple groups of transverse reinforcement ribs 14 arranged inside the reinforcement layer 13 can effectively improve the overall strength of the baffle 5 to avoid being bent and deformed. The multi-layer design of the baffle 5 can block large particles of sand and gravel through the galvanized iron mesh layer 11, and the middle nylon filter cloth layer 12 can filter cement slurry to prevent leakage. The galvanized iron mesh layer 11, the nylon filter cloth layer 12 and the reinforcement layer 13 can all be disassembled, cleaned and replaced for easy use.

[0028] Observe the correspondence between the first spring block 21 and the scale tooth groove 22. After reaching the required height, push the handle 35 so that the connecting buckle 36 pushes the connecting rods 37 and the rotating buckle 34 on both sides, so that the control rods 16 on both sides slide horizontally. The control rod 16 drives the device box 20 to slide, so that the tip of the first spring block 21 is engaged and limited with the scale tooth groove 22. At the same time, the control rod 16 will also drive the sliding rods 18 on both sides to slide horizontally, so that the sliding frame 30 drives the second spring block 31 to slide, and the tip of the second spring block 31 is inserted into the oblique tooth groove 32 for engagement, which can prevent the winding shaft 28 from continuing to rotate and the flow blocking member 5 from continuing to loosen, so that the flow blocking member 5 is initially tightened as a whole, avoiding the situation in which the middle part of the flow blocking member 5 is subjected to force during the subsequent flow blocking process, causing the winding shaft 28 to continue to rotate.

[0029] It is worth noting that: this structure is designed to bend the baffle 5 at the bottom so that the baffle 5 as a whole has a six-layer structure, and the structures on the outer sides are galvanized iron mesh layers 11, which improves the flow blocking efficiency and structural stability, and when in use, only the baffle 5 at one end is used. After use, the adjusting rod 6 is reset to the bottom, so that the double-layer baffle 5 can be flattened into one layer, which is convenient for subsequent cleaning and use, and also ensures that the excess baffles 5 inside the box cover 41 will not be used frequently. When the outer baffle 5 is severely damaged and cannot be used anymore, the baffle 5 is directly cut off horizontally from the middle as a whole, and then the cut position is fixed to the bottom of the adjusting rod 6 along the guide groove 8, which is convenient for replacement and use.

[0030] When the second regulating rod 6 is moved upward, the control rods 16 on both sides are pushed out slightly to the sides so that the control rods 16 can block the control rods 16 extending next to the regulating rods 16. When the top surface of the regulating rod 16 in the lifting state conflicts with the bottom surface of the regulating rod 16 in the static state, the regulating rod 6 cannot slide up further. At this time, directly pushing the handle 35 can complete the limit of the regulating rod 6 of the group, and at the same time, the control rods 16 on both sides are fully pushed out, which is convenient for the subsequent adjustment and limit of the adjacent regulating rods 6. In this way, there is no need to calculate and control the adjustment height of each group of regulating rods 6. It can be directly slid up to the blocked position, which is convenient and efficient.

[0031] It is worth noting that the extension of the above-mentioned control rod 16 is to prevent the adjustment rod 6 from being blocked when the adjacent flow-blocking device is installed as a whole. At the same time, the position of the control rod 16 can be automatically limited when the adjustment rod 6 slides up, thereby improving the efficiency of installation and adjustment. When it needs to be disassembled, the handle 35 can be directly pulled out to retract the control rod 16 into the adjustment rod 6. At this time, the first side rod 1 and the second side rod 2 are pulled upward, and the control rods 16 on both sides will not cause obstruction, which facilitates disassembly. The device can ensure that the flow-blocking surfaces on both sides are vertical planes. Compared with traditional grid structures, it is flatter and has greater support strength. Traditional mesh structures are prone to wrinkles and the like during adjustment, and are prone to bending in the middle due to thrust during the flow-blocking process, affecting usage efficiency.
