Improved soft film nozzle push correction tape

Abstract

The invention discloses an improved soft film push nozzle correction belt, which comprises a casing, an inner core sliding part movable in the casing, a nozzle opening for stretching and contracting of the nozzle is opened on the casing, and an arc-shaped Guide groove, a flexible diaphragm is installed on the arc-shaped guide groove, and a sliding guide rib for pushing and closing the nozzle is also provided on the housing. In the folded rib part, the inner core slider is equipped with an elastic rib buckle that matches the sliding guide rib. When the mouth is closed, the soft diaphragm is in conflict with the elastic rib buckle, and then the soft diaphragm slides to drive the inner core slider to slide smoothly. Close the nozzle, and at the same time, the elastic rib buckle slides to the bent rib to complete the reset, which solves the problem in the traditional technology that the nozzle groove and the pressure nozzle conflict with each other when closing the nozzle, resulting in poor nozzle closing. The present invention realizes opening and pushing the nozzle, closing the nozzle and closing the nozzle through mutual cooperation among the sliding guide rib, the elastic rib buckle and the soft diaphragm.

Description

technical field [0001] The invention relates to a correction tape, in particular to an improved correction tape with soft membrane push nozzle. Background technique [0002] The applicant of this case applied for a patent with the authorized announcement number CN 104773016 B on July 15, 2017 (the application number is 2015101808903, and the invention name is a soft film push nozzle correction tape). It can expand and contract with the correction belt body and open and close the pressure mouth accordingly, but this correction belt has the following problems in the process of use: in the process of closing the nozzle, the sliding part of the inner core cannot go smoothly due to insufficient thrust and other reasons. back sliding, resulting in the pressure nozzle not being fully retracted in the housing. When the pressure nozzle is in a semi-closed state, the end edge of the soft diaphragm corresponding to the pressure nozzle is not fully retracted in the housing as expected. ...

[0002] The applicant of this case applied for a patent with the authorized announcement number CN 104773016 B on July 15, 2017 (the application number is 2015101808903, and the invention name is a soft film push nozzle correction tape). It can expand and contract with the correction belt body and open and close the pressure mouth accordingly, but this correction belt has the following problems in the process of use: in the process of closing the nozzle, the sliding part of the inner core cannot go smoothly due to insufficient thrust and other reasons. back sliding, resulting in the pressure nozzle not being fully retracted in the housing. When the pressure nozzle is in a semi-closed state, the end edge of the soft diaphragm corresponding to the pressure nozzle is not fully retracted in the housing as expected. The part of the nozzle that is still outside the nozzle is in conflict, which makes it difficult to close the nozzle smoothly, and the nozzle cannot be closed smoothly

Although this improvement scheme can successfully realize nozzle closure, the cost of the product becomes higher and the processing efficiency becomes lower. In addition, the extension spring is easily damaged during repeated use, which affects the service life of the correction tape.
