[0007] According to the above technical solution, as a further preferred technical solution of the above technical solution, one end of the locking rod is provided with a latch portion that cooperates with the first fixing ring, and the other end of the locking rod is provided with a rolled portion that cooperates with the second fixing ring.
[0008] According to the above technical solution, as a further preferred technical solution of the above technical solution, the latch portion is cooperatively connected with the sleeve.
[0009] According to the above technical solution, as a further preferred technical solution of the above technical solution, first fixing holes are respectively provided at the upper and lower ends of the first fixing plate.
[0010] According to the above technical solution, as a further preferred technical solution of the above technical solution, second fixing holes are respectively provided at the upper and lower ends of the second fixing plate.
[0011] According to the above technical solution, as a further preferred technical solution of the above technical solution, third fixing holes are respectively provided at the upper and lower ends of the extension portion.
[0012] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0013] The utility model provides a rolled pull bolt lock, which is provided with an extension portion at the bottom of the second fixed plate and a sleeve on the surface of the extension portion. When not in use, the latch portion of the lock rod can be inserted into the sleeve, which can prevent the lock rod from swinging back and forth when the door body is opened and closed, thereby increasing practicality.
