Description

Technical Field

[0001] This utility model relates to the field of flat knitting machine technology, and more specifically, to a bottom plate opening and closing door locking structure and a flat knitting machine. Background Technology

[0002] In a computerized flat knitting machine equipped with a base plate, elastic yarn is used for the initial knitting. After one rotation of the knitting machine, the rollers open, and the base plate rises. The composite needles on the base plate hook onto the elastic yarn and pull it downwards. Then, the fabric yarn enters the knitting process, and the yarn loops are hooked by the elastic yarn and pulled downwards by the base plate. Once the base plate has fallen to a safe position, the rollers close to clamp the fabric, the composite needles on the base plate release the elastic yarn, the base plate returns to its original position, and the fabric falls through a protective plate into the fabric receiving device.

[0003] The protective panel uses an opening and closing door structure. A movable door latch is located on the inner side of the door, and a lock hole is located inside the knitting machine body to engage with the movable door latch. The movable door latch can be pulled out of the lock hole and rotated around the bottom pivot. Currently, the movable door latch is opened and closed by a lever. A through hole is provided on the door panel, through which the lever extends. The operator pushes the lever from the outside of the door to open and close it. Because the lever extends outside the door, if the fabric is blocked during its fall, it will be obstructed and unable to fall smoothly.
