[0003] During synthesis, usually a syringe filled with materials is inserted into a rotating table. The size of the syringe used for each synthesis is different. When inserting, an auxiliary tool is needed to fix the syringe, which reduces the work efficiency. Therefore, we provide a microfluidic synthesis device for silver nanofluid. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a microfluidic synthesis device for silver nanofluid. By rotating the friction ring, the size of the adjustment block can be adjusted so that it can adjust itself according to the size of the syringe, solving the problem that the size of the syringe used for each existing synthesis is different and an auxiliary tool is needed to fix the syringe when inserting, resulting in a reduction in work efficiency.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

A locking mechanism is arranged on the right side of the synthesis mechanism. The bottom of the rotating table is fixedly connected with a fixing plate. The bottom of the fixing plate is slidably connected with a rotating ring. The inner side of the rotating ring is rotatably connected with a connecting rod. There are five connecting rods in total. The five connecting rods are arranged in an annular array with the center of the rotating ring. The connections inside the five connecting rods are the same. The end of the connecting rod far away from the rotating ring is rotatably connected with an adjustment block;
[0007] A positioning rod is rotatably connected inside the adjustment block. The top of the positioning rod is fixedly connected with the bottom of the fixing plate. A sliding groove one is opened inside the rotating ring. The inner wall of the sliding groove one is slidably connected with a sliding rod. The top of the sliding rod is fixedly connected with the bottom of the fixing plate. By rotating the friction ring, the size of the adjustment block can be adjusted so that it can adjust itself according to the size of the syringe.
[0008] Furthermore, a second sliding groove is formed inside the rotating ring. A fixing rod is slidably connected to the inner wall of the second sliding groove. The top of the fixing rod is fixedly connected to the bottom of the fixing plate. The bottom of the fixing rod penetrates through the rotating ring and extends to the outside. A cover plate is fixedly connected to the bottom of the fixing rod. A friction ring is fixedly connected to the outer surface of the rotating ring. The inner wall of the friction ring is rotatably connected to the outer surface of the cover plate. The cover plate and the bottom plate are connected by the fixing rod.
[0009] Furthermore, a mounting plate is inserted into the inner wall of the rotating table. A synthetic plate is inserted into the mounting plate. A flow groove is formed inside the synthetic plate. A clamping block is fixedly connected to the front of the rotating table. A mounting groove is formed inside the rotating table. A rotating shaft is fixedly connected to both the left side and the right side of the rotating table. There are two rotating shafts in total. A clamping groove is formed on the right side of the rotating shaft located on the right side. By fixing the clamping groove, the rotating table cannot rotate.
[0010] Furthermore, the locking mechanism includes a synthetic box. The inner wall of the synthetic box is rotatably connected to the outer surface of the rotating shaft. A motor is fixedly connected to the inside of the synthetic box. A threaded rod is fixedly connected to the output end at the top of the motor. A push block is threadedly connected to the outer surface of the threaded rod. By rotating the threaded rod, the push block is pushed upward to extrude the syringe and make the material inside flow out.
[0011] Furthermore, a gear is rotatably connected to the outer surface of the top of the threaded rod. A rack is meshed and connected to the left side of the gear. The left side of the rack is in contact with the right side of the clamping groove. A slider is fixedly connected to the left side of the rack.

The rotating shaft is limited by the gear to prevent the rotating table from rotating during the synthesis process, causing the syringe to tilt and avoiding breakage of the syringe when the push block pushes the syringe upward.
[0013] The utility model has the following beneficial effects:
[0014] 1. The utility model fixes a syringe by setting an adjusting block and rotating a friction ring. When the friction ring rotates, it drives a rotating ring to rotate. When the rotating ring rotates, it pulls a connecting rod. When the connecting rod moves, it drives the adjusting block to move outward, opening a through hole. Then, the syringe is passed through the through hole, and the output head of the syringe is connected to the bottom of a synthetic plate. After the connection is completed, the friction ring is rotated in the reverse direction, so that the adjusting block moves back towards the center to fix the syringe. By rotating the friction ring, the size of the adjusting block can be adjusted, enabling it to adjust itself according to the size of the syringe.
[0015] 2. The utility model prevents a rotating table from rotating during the synthesis process by setting a rotating shaft. When the motor starts, it drives a threaded rod to rotate. When the threaded rod rotates, it drives a push block to move upward. At the same time as the threaded rod rotates, it drives a gear to rotate. When the gear rotates, it pushes a rack forward, causing it to engage in a card slot to limit the rotation of the rotating shaft, preventing the syringe from tilting when the push block moves upward to push the syringe, and avoiding breakage of the syringe.
[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figures 1-7 As shown, the present invention is a microfluidic synthesis device for silver nanofluids, including a synthesis mechanism 2 and a rotating table 201.

[0029] A positioning rod 218 is rotatably connected inside the adjustment block 216. The top of the positioning rod 218 is fixedly connected to the bottom of the fixed plate 209. A first sliding groove 214 is formed inside the rotating ring 213. A sliding rod 211 is slidably connected to the inner wall of the first sliding groove 214. The top of the sliding rod 211 is fixedly connected to the bottom of the fixed plate 209. There is a rotating friction ring 212. The rotation of the friction ring 212 drives the rotation of the rotating ring 213. By rotating the rotating ring 213, the connecting rod 217 is pulled. By moving the connecting rod 217, the adjustment block 216 is driven to move so that the adjustment block 216 moves outward, opening the through hole. Then, the syringe is passed through it. The output head of the syringe is connected to the bottom of the synthetic plate 203. After the connection is completed, the friction ring 212 is reversed, so that the adjustment block 216 moves back towards the center to fix the syringe. By rotating the friction ring 212, the size of the adjustment block 216 can be adjusted so that it can be adjusted according to the size of the syringe itself.
[0030] A second sliding groove 215 is formed inside the rotating ring 213. A fixing rod 210 is slidably connected to the inner wall of the second sliding groove 215. The top of the fixing rod 210 is fixedly connected to the bottom of the fixed plate 209.

There are two rotating shafts 206 in total. A clamping groove 207 is formed on the right side of the rotating shaft 206 located on the right.
[0033] The locking mechanism 1 includes a synthetic box 101. The inner wall of the synthetic box 101 is rotatably connected to the outer surface of the rotating shaft 206. A motor 102 is fixedly connected inside the synthetic box 101. A threaded rod 104 is fixedly connected to the top output end of the motor 102. A push block 103 is threadedly connected to the outer surface of the threaded rod 104.
[0034] The outer surface of the top of the threaded rod 104 is rotatably connected to a gear 105. The left side of the gear 105 is meshed and connected to a rack 106. The left side of the rack 106 is in contact with the right side of the card slot 207. The left side of the rack 106 is fixedly connected to a slider 107. When the motor 102 starts, it drives the threaded rod 104 to rotate. By the rotation of the threaded rod 104, the push block 103 is driven to move upward. While the threaded rod 104 rotates, it will drive the gear 105 to rotate. While the gear 105 rotates, the rack 106 is pushed forward, so that it is inserted into the card slot 207 to limit the rotation shaft 206, preventing the rotating table 201 from rotating during the synthesis work, causing the syringe to tilt, and causing the syringe to break when the push block 103 pushes the syringe upward.
[0035] A chute 109 is provided inside the synthesis box 101. The inner wall of the chute 109 is slidably connected to the outer surface of the slider 107. The back of the slider 107 is fixedly connected to a first spring 108. The back of the first spring 108 is fixedly connected to the inner wall of the chute 109.
[0036] A second chute 112 is provided inside the threaded rod 104. The inner wall of the second chute 112 is fixedly connected to a second spring 111. The other end of the second spring 111 is fixedly connected to a convex block 110. The outside of the convex block 110 penetrates through the threaded rod 104 and extends into the gear 105.
[0037] A specific application of this embodiment is as follows: First, the staff opens the rotating table 201, then loads the material into the syringe, then tilts the rotating table 201, and then rotates the friction ring 212. The rotation of the friction ring 212 drives the rotation of the rotating ring 213. By rotating the rotating ring 213, the connecting rod 217 is pulled. The movement of the connecting rod 217 drives the adjustment block 216 to move, causing the adjustment block 216 to move outward, opening the through hole. Then, the syringe is passed through it, and the output head of the syringe is connected to the bottom of the composite plate 203. After the connection is completed, the friction ring 212 is reversed, so that the adjustment block 216 moves back towards the center to fix the syringe. By rotating the friction ring 212, the size of the adjustment block 216 can be adjusted so that it can be adjusted according to the size of the syringe. After the installation is completed, the collection tube is installed on the clamping block 205, and the rotating table 201 is pushed downward to reset it. Then, the motor 102 is started. The start of the motor 102 drives the rotation of the threaded rod 104. By rotating the threaded rod 104, the push block 103 moves upward. While the threaded rod 104 rotates, the gear 105 is driven to rotate. While the gear 105 rotates, the rack 106 is pushed forward to engage it into the card slot 207 to limit the rotation shaft 206, preventing the rotating table 201 from rotating during the synthesis work, causing the syringe to tilt and the syringe to break when the push block 103 pushes the syringe upward. After the rack 106 is engaged into the card slot 207, the rack 106 will not move forward. Therefore, the fixation of the rack 106 will hold the gear 105. Since the convex block 110 is spherical and the threaded rod 104 continues to rotate, the convex block 110 will be squeezed into the second chute 112, thus leaving the groove in the gear 105. Therefore, the threaded rod 104 can continue to rotate.
