The background art of this mechanism puts forward the problem that "in the existing filling method, commonly, manual use of a liquid injection gun to fill a tank container cannot ensure quantitative filling". For this reason, the technical solution to solve this problem in this scheme is "including a conveying barrel and a quantitative component. The quantitative component includes a motor, and the motor is arranged at the left part of the conveying barrel; the rotating shaft is fixedly connected to the output end of the motor; the gear is fixedly connected to the outer wall of the rotating shaft; the rack is meshed with the gear; the connecting rod is fixedly connected to the right part of the rack; the piston is fixedly connected to the right part of the connecting rod, and the piston is slidably connected to the inner wall of the conveying barrel", etc.

When adjusting the filling quantity, it is necessary to reprogram and debug the number of rotation circles of the motor to change the moving distance of the rack, and the process is relatively cumbersome and complex, which is likely to increase the downtime of filling, resulting in a reduction in the convenience, flexibility, and filling efficiency. For this reason, we provide a quantitative filling mechanism to solve the above problems. Summary of the Utility Model

A rotating rod 207 is fixedly installed on the surface of one end of the screw rod 205;

[0028] A driving mechanism 208 provided on the base 100 and connected to the screw rod 205. The driving mechanism 208 drives the threaded cylinder 203 and the piston block 204 to reciprocate through the screw rod 205 to suck or discharge liquid;

[0029] And a placement mechanism 400 provided on the base 100 for supporting the filling tank.

[0030] Specifically: The driving mechanism 208 includes a motor one 208a fixedly installed on one side of the top of the base 100 through a bracket one, a rotating plate 208b fixedly connected to the output end of the motor one 208a, a connecting plate 208c rotatably connected to one side surface of one end of the rotating plate 208b, and a fixed block 208d rotatably connected to one side surface of one end of the connecting plate 208c. The fixed block 208d is rotatably connected to the screw rod 205.

[0031] Specifically: The liquid storage mechanism 300 includes a liquid storage tank 301 fixedly installed on the top of the base 100 through a bracket two and connected to the liquid infusion pipe 202, and a liquid injection pipe 302 fixedly installed on one side of the top of the liquid storage tank 301. A end cover is threadedly connected to the top of the liquid injection pipe 302.

[0032] Specifically: The placement mechanism 400 includes a placement box 401 fixedly installed on one side of the bottom of the base 100 through a third bracket, a box cover 402 hinged to one side of the placement box 401, two magnet blocks 403 respectively fixedly installed on one side of the placement box 401 and the box cover 402 and magnetically adsorbed to each other, and protective pads 404 fixedly installed on the inner walls of the placement box 401 and the box cover 402. A handle is fixedly installed on one side of the box cover 402, and the protective pad 404 is made of rubber material.

[0033] The operation process of this embodiment is as follows: When in use, by opening the end cover on the liquid injection pipe 302, the liquid enters the liquid storage tank 301 for storage. Then, hold the handle to open the box cover 402, place the tank to be filled in the placement box 401, and protect the tank through the protective pad 404 to avoid damage to the tank caused by collision.

[0035] Finally, drive the rotating plate 208b to rotate through the first motor 208a, and drive the connecting plate 208c to move through the rotating plate 208b. Thus, drive the screw rod 205, the threaded cylinder 203 and the piston block 204 to move away from the drain pipe 201, so that a negative pressure is formed in the metering cylinder 200. At the same time, the second one-way valve opens, and the liquid in the liquid storage tank 301 is pumped into the metering cylinder 200 through the infusion pipe 202. When the rotating plate 208b rotates to a position close to the metering cylinder 200, the piston block 204 moves towards the drain pipe 201. At this time, the first one-way valve opens, so that the liquid in the metering cylinder 200 is discharged into the tank through the drain pipe 201, and thus the purpose of quantitative filling is achieved.
