The utility model discloses an ink production is with storage tank, belong to ink production device technical field. The utility model discloses a storage tank body, scraper and support, be equipped with the storage cavity in the storage tank body, the scraper is contacted with the inner wall of storage cavity, the outer surface of scraper is equipped with counterweight, is equipped with the guide rail in the storage tank body, and the guide rail is linked together with storage cavity, and the counterweight is slidably fitted in the guide rail. The utility model discloses the scraper and counterweight who sets up the ink scraping of storage cavity inner wall, so that when the storage tank body is inclined to a certain angle and pours out the ink, the counterweight slides down along the guide rail, drives the annular scraper and scrapes the ink remaining on the inner wall of the storage tank body, and the counterweight drives the scraper reset when the storage tank body is back to normal, avoids the sealing problem and cost increase problem of using electric push rod, and the structure is simple with the mode of gravity drive, and reliable operation reduces the failure rate and maintenance cost of equipment.

The utility model discloses a kind of urethral dosing devices, belong to medical instrument technical field, the urethral dosing device, comprising: syringe, the side of syringe is extended and is provided with support ring, the top surface of support ring is fixedly connected with dosing tube, recessed groove is opened in the outer wall of dosing tube;And fixed component, fixed component includes: front section air bag, connecting air pipe, silica gel air bag and secondary buckle, front section air bag is sleeved in recessed groove, connecting air pipe is arranged in the inside of dosing tube, and one end of connecting air pipe extends to the outside of dosing tube, connecting air pipe and front section air bag are communicated. The urethral dosing device, by syringe containing liquid medicine, dosing tube and silica gel dosing head reduce the stimulation to urethra when applying medicine, front section air bag and fossa navicularis cooperate, and fossa navicularis is plugged, prevent liquid medicine back suction, simultaneously can be loosened buckle after drug action is finished, and the excess liquid medicine is sucked out, liquid medicine can reach urethral deep part, improve the effect of drug.

The utility model relates to story machine shell mould technical field discloses a story machine shell mould structure, including top positioning assembly, the top of top positioning assembly is fixedly connected with buffer spring, the top of top positioning assembly is fixedly connected with buffer support, the top of top positioning assembly is fixedly connected with fixed stand, the top of top positioning assembly is fixedly connected with positioning pin. The utility model discloses through setting up the fixed ring in the limiting roof and the contact of injection pipe top, disperses the impact of injection pressure to the mould, prevents the cracking caused by local stress concentration, and simultaneously acts as the security barrier, blocks the sputtering risk of high temperature plastic, through setting up the plugging thimble and sliding in the injection pipe, cooperates the fixed ring limit, realizes the injection port opening and closing control, avoids the waste of overflow material, and the thimble closes the runner in the injection completion stage, prevents the phenomenon of back suction, and improves the yield.
