The entire reagent rack can be disassembled into multiple parts, and the space occupied by all parts is small when all parts are folded up.

[0004] However, the inventor of the above device believes that it has certain defects. The distance between the multiple trays of the above device is not easy to adjust, and the distance between adjacent trays cannot be adjusted according to the size of the reagent bottle, resulting in low practicality. In addition, it lacks a fixing mechanism to fix the reagent tubes or reagent bottles, resulting in poor stability of the reagent tubes or reagent bottles. Therefore, this utility model provides a flexible clamping experimental reagent rack. Utility Model Content

[0005] The purpose of this invention is to provide a flexible clamping reagent rack to solve the above-mentioned problems. This solves the problems in the prior art where the distance between multiple trays is not easy to adjust, the distance between adjacent trays cannot be adjusted according to the size of the reagent bottle, the practicality is low, and there is a lack of fixing mechanism to fix the reagent tubes or reagent bottles, resulting in poor stability of the reagent tubes or reagent bottles.

[0006] This utility model is achieved through the following technical solution: a flexible clamping reagent rack, including a fixed base plate, two support frames fixedly connected to the top of the fixed base plate, multiple mounting plates sliding between the two support frames, multiple test tube clamps mounted on each mounting plate, and a limiting mechanism provided on the mounting plate to restrict the sliding of the mounting plate between the two support frames. Each test tube clamp includes a fixed sleeve fixed to the mounting plate, a sliding rod slidingly attached to one end of the fixed sleeve, a mounting top frame fixedly connected to the top of the sliding rod, two clamping blocks slidingly connected to the mounting top frame, multiple sets of sliding cavities opened on one side of each clamping block, a movable clamping rod slidingly attached inside each sliding cavity, and one end of the movable clamping rod connected to the inner wall of the sliding cavity by a second spring.

[0007] Preferably, the limiting mechanism includes fixed seats fixed to both ends of the mounting plate, and each fixed seat has a movable insert rod slidably connected inside. The support frame has side insertion holes, and both ends of the movable insert rod are inserted into the side insertion holes. The position of the mounting plate is fixed by inserting both ends of the movable insert rod into the side insertion holes.

[0008] Preferably, there are multiple sets of side insertion holes, and the movable insertion rod is U-shaped, so that both ends of the movable insertion rod can be easily pulled out from the inside of the side insertion hole by pulling the movable insertion rod.

[0009] Preferably, the top of the mounting frame is provided with a sliding groove, and a sliding block is slidably connected inside the sliding groove.

[0013] This invention provides a flexible clamping reagent rack, which has the following beneficial effects:

[0014] 1. The device uses a support frame, mounting plate, and limiting mechanism to slide the mounting plate up and down to adjust the distance between the mounting plates. The reagent tube is placed between two clamping blocks, and the two clamping blocks are driven to move closer to each other. Under the action of the clamping blocks, movable clamping rod, sliding cavity, and second spring, a flexible clamp is formed to quickly clamp the reagent tube. It can clamp reagent tubes of different diameters, which improves the adaptability of the device.

[0015] 2. This device pushes the mounting bracket downwards by one end of the reagent tube, which in turn pushes the sliding rod into the fixed sleeve.

[0023] This utility model provides a flexible clamping reagent rack.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A flexible clamping reagent rack includes a fixed base plate 1, with two support frames 2 fixedly connected to the top of the fixed base plate 1. Multiple mounting plates 3 slide between the two support frames 2, and multiple test tube clamps 4 are installed on each mounting plate 3. The distance between each mounting plate 3 is adjusted by controlling the sliding of the mounting plate 3 between the two support frames 2, and the reagent tubes are clamped and fixed by the test tube clamps 4.

[0025] Please refer to it again. Figure 1 The mounting plate 3 is provided with a limiting mechanism that restricts the sliding of the mounting plate 3 between the two support frames 2. The limiting mechanism includes fixed seats 31 fixed at both ends of the mounting plate 3. Each fixed seat 31 has a movable insert rod 32 slidably connected inside. The support frame 2 has a side insertion hole 21. Both ends of the movable insert rod 32 are inserted into the side insertion hole 21. By pulling the two ends of the movable insert rod 32 out of the side insertion hole 21, the mounting plate 3 can slide between the two support frames 2 to adjust the distance between each mounting plate 3. There are multiple sets of side insertion holes 21. The movable insert rod 32 is U-shaped. The U-shaped movable insert rod 32 is easy to pull and slide inside the fixed seat 31.

[0026] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The test tube clamp 4 includes a fixed sleeve 5 fixed on the mounting plate 3. A sliding rod 6 is slidably connected to one end of the fixed sleeve 5. A mounting top frame 7 is fixedly connected to the top of the sliding rod 6. Two clamping blocks 9 are slidably connected to the mounting top frame 7. A sliding groove 71 is opened on the top of the mounting top frame 7. A sliding block 72 is slidably connected inside the sliding groove 71. The clamping blocks 9 are fixedly connected to the sliding block 72. Under the action of the sliding block 72, the two clamping blocks 9 slide on the mounting top frame 7 by controlling the sliding of the two sliding blocks 72. When the two clamping blocks 9 come close to each other, they clamp and fix the reagent tube.

[0027] Please refer to it again. Figure 1 , Figure 2 and Figure 4 Each clamping block 9 has multiple sets of sliding cavities 92 on one side. Each sliding cavity 92 has a movable clamping rod 91 sliding inside. One end of the movable clamping rod 91 is connected to the inner wall of the sliding cavity 92 by a second spring 93. When the two clamping blocks 9 approach each other, the outer wall of the reagent tube squeezes the movable clamping rod 91 to retract into the sliding cavity 92, thereby clamping the reagent tube between the two clamping blocks 9 to form a flexible clamp. When the two clamping blocks 9 move away from each other, the rebound of the second spring 93 quickly drives each movable clamping rod 91 to slide back to its original position.

[0028] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 5 The bottom of the sliding block 72 is hinged to a pressing rod 52 by a pin. A fixed rod 51 is fixedly connected to the fixed sleeve 5. The other end of the pressing rod 52 is hinged to one end of the fixed rod 51 by a pin. By pushing the mounting bracket 7 down, the sliding rod 6 slides into the fixed sleeve 5. The pressing rod 52 pushes the two sliding blocks 72 closer to each other. A first spring 8 is installed inside the sliding groove 71. The sliding block 72 is connected to the inner wall of the sliding groove 71 by the first spring 8. When the mounting bracket 7 rises, the rebound of the first spring 8 quickly drives the two clamping blocks 9 to slide away from each other.

[0029] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 5 The sliding rod 6 is slidably connected to the top of the fixed sleeve 5, and a magnet 10 is fixedly connected to the bottom of the sliding rod 6. A fixed iron plate 12 is fixedly connected to the inner bottom wall of the fixed sleeve 5. When the sliding rod 6 slides into the fixed sleeve 5, the fixed iron plate 12 is attracted by the magnet 10 to fix the position of the sliding rod 6. When it is necessary to release the clamp on the reagent tube, the mounting bracket 7 needs to be manually pushed up to separate the fixed iron plate 12 from the magnet 10.

[0030] Working principle: Install the device in a suitable position, and pull the movable insertion rod 32 to slide it on the fixed base 31 so that both ends of the movable insertion rod 32 are pulled out from the inside of the side insertion hole 21. Adjust the mounting plate 3 to slide between the two support frames 2 to adjust the distance between the mounting plates 3. After adjustment, reinsert both ends of the movable insertion rod 32 into the inside of the side insertion hole 21. Then place the reagent tube to be fixed between the two clamping blocks 9. Push the mounting top frame 7 down through one end of the reagent tube, so that the sliding rod 6 slides into the inside of the fixed sleeve 5. Under the squeezing action of the squeezing rod 52, push the two sliding blocks 72 to slide closer to each other. The two clamping blocks 9 clamp the reagent tube. The outer wall of the reagent tube squeezes the movable clamping rod 91 to retract into the sliding cavity 92 to clamp the reagent tube between the two clamping blocks 9 to form a flexible clamp. When the sliding rod 6 slides into the fixed sleeve 5, the magnetic block 10 attracts the fixed iron plate 12 to fix the position of the sliding rod 6.
