Description
Technical field
The present invention relates to a kind of door lock.
Background technology
As shown in Figure 1, be used for the door lock on the circular knitting machine at present, comprise: be arranged on the buckle 6 on the support 1, activity is located in the operating grip 3 on the revolving door 2, and the elongated insertion part 5 that is arranged on operating grip 3 ends.When opening revolving door 2, pull operating grip 3, drive elongated insertion part 5 and upwards rotate, make elongated insertion part 5 separate, outwards spur revolving door 2 then, make it to be in open mode with buckle 6 with hand; When closing revolving door 2, earlier revolving door 2 is closed, then, pull operating grip 3 in the other direction, drive elongated insertion part 5 and rotate, make elongated insertion part 5 and buckle 6 overlap together, with revolving door 2 lockings.The door lock of this structure, its structure more complicated, cost is higher, and it is cumbersome to operate; And long-term the use, can make that operating grip 3 is active loosening, cause elongated insertion part 5 automatically-unhooked, thereby cause revolving door 2 frequent improper opening.
Summary of the invention
