[0002] A syringe is a qualitative and quantitative experimental device and can be used for reactions between substances in various states. For example, gas-gas reactions, liquid-liquid reactions, or gas-liquid reactions can all be completed with a syringe.

[0003] However, there are also some deficiencies in the use of syringes. For example, it is rather troublesome to complete reactions between solid substances or between solid and gas substances with a syringe, and it is inconvenient to put materials into the syringe. Therefore, this technical solution proposes a syringe for experiments to solve the above-mentioned problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages that it is rather troublesome to complete reactions between solid substances or between solid and gas substances with a syringe in the prior art, and it is inconvenient to put materials into the syringe, and to propose a syringe for experiments.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A syringe for experiments includes a syringe tube. A joint tube is arranged at the bottom of the syringe tube and is communicated with the syringe tube. A piston plate is hermetically and slidably connected in the syringe tube. A moving tube is fixedly installed at the top of the piston plate. The top end of the moving tube extends above the syringe tube and is fixedly installed with a connecting plate. The syringe further includes:

[0007] A material blocking cover is fixedly installed on the inner wall of the bottom of the syringe tube. A plurality of filtering holes are equidistantly arranged on the inner wall of the side surface of the material blocking cover. The filtering holes are used for filtering solid substances placed in the syringe tube;

[0008] A feeding tube. An installation hole is arranged on the inner wall of the bottom of one side of the syringe tube.

[0009] A blocking mechanism is installed in the feeding tube and is used for blocking the feeding tube;

[0010] An adjusting mechanism is installed at the top of the syringe tube and is connected with the connecting plate.

[0011] In a possible design, the plugging mechanism includes an external threaded pipe fixedly sleeved on the feeding pipe, and a threaded cap is threadedly connected to the external threaded pipe.

[0012] In a possible design, a sealing plug is fixedly installed on the inner wall of one side of the threaded cap, one side of the sealing plug extends into the feeding pipe, and the sealing plug is in close fit with the inner wall of the feeding pipe.

[0013] In a possible design, the adjusting mechanism includes a support frame fixedly installed on the top of the syringe tube. A screw rod is rotatably connected through the support frame. A nut is fixedly installed on the top of the connecting plate. The bottom end of the screw rod respectively penetrates through the nut and the connecting plate and extends into the moving pipe. The screw rod is threadedly connected to the nut. A baffle is fixedly installed at the bottom end of the screw rod, and the baffle is used to limit the connecting plate.
