Tape for paint repair

ActiveCN224619872Uplay the role of positioningimpenetrable
This application discloses an adhesive tape for paint repair, relating to the field of automotive paint repair. It includes a base layer, a barrier film layer fixedly installed on top of the base layer, an outer layer fixedly installed on top of the barrier film layer, and an adhesive layer at the bottom of the base layer. The adhesive layer has a positioning mechanism at its bottom for positioning the base layer, and the positioning mechanism includes a release paper layer disposed at the bottom of the adhesive layer. This application allows the second positioning paper layer of the release paper layer to be peeled off via a second easy-tear portion. At this point, one side of the tape can be adhered to the designated position. Then, the first positioning paper layer is peeled off, and the tape is adhered again. Finally, the third positioning paper layer is peeled off via a third easy-tear portion, completing the tape's adhesion and positioning. Therefore, the tape effectively positions the tape during application, provides high edge adhesion, and prevents paint penetration while isolating the topcoat.

A sputum testing sampler

ActiveCN224269343UAvoid bubbles and splashingimpenetrableSurgeryVaccination/ovulation diagnosticsAirbagMedical device
This utility model relates to the field of medical device technology, and in particular to a sputum sampling device, comprising a long tube with one end shaped like a frustum. A piston is installed inside the long tube, and a push-pull assembly is provided at the piston. A sealing block is slidably mounted at one end of the long tube, with the vertical projection of the piston located on the sealing block. An adjustment assembly is provided at the sealing block to adjust the sealing performance of the sealing block at one end of the long tube. A sleeve is connected to the outside of the long tube, and a groove is formed on one side of the top of the sleeve. A movable block is slidably mounted on the groove, and a connecting rod is provided between one side of the movable block and one side of the piston. The connecting rod is curved. During one-handed operation, the operator's thumb can move the movable block within the groove, causing the movable block to move along with the connecting rod. The connecting rod, in turn, moves the piston within the long tube, reducing the difficulty of suctioning sputum and thus avoiding the formation of air bubbles and splashing of sputum caused by the airbag.
