The pipe body is communicated with the bottom of the shell; the pipe wall of the pipe body is provided with a notch
A locking shaft; the locking shaft is positioned in the tube body;
the axis of locking axle coincides with the axis of body mutually, and the cover is equipped with the gear on the locking axle, and the gear is located the opening part of body and casing through connection, makes things convenient for gear and pivot cooperation to rotate.
A ratchet wheel; the ratchet wheel is sleeved on the locking shaft and is positioned in the tube body; a pawl; the pawl penetrates through the gap and abuts against the ratchet wheel to limit the rotation of the locking shaft;
that is to say, the tip of pawl passes the breach on the body and offsets with the working face of ratchet, and the ratchet is located the body, can effectually protect the ratchet, and the width of breach is unanimous with, pawl width, ratchet thickness simultaneously, can effectually guarantee the quick location of pawl and ratchet, prevents that the pawl from taking place the wrong tooth with the ratchet, influences locking strength.
How to further protect the ratchet wheel, the utility model adopts a cover body with a notch positioned at the end part of the pipe wall of the pipe body and covered with the pipe orifice of the pipe body, and the cover body is sleeved on the locking shaft;
the notch is arranged at the end part of the pipe wall of the pipe body, so that the ratchet wheel can be conveniently overhauled and disassembled, the cover body can prevent impurities from entering from the pipe orifice of the pipe body, and the cover body can also realize the limiting effect and limit the ratchet wheel in the pipe body.
How to fix the pawl, the utility model adopts the structure that a support plate is fixedly arranged at the bottom of a shell, a support column parallel to a locking shaft is arranged on the support plate, and the support column is connected with the middle part of the pawl through a spring;
the pawl rotates along the support column, the working surface of the pawl is abutted to the ratchet wheel, and when the working surface of the pawl is abutted to the ratchet wheel under the action of the spring, the spring gives a certain thrust.
The utility model has the advantages that: the utility model relates to a starter locking protection device, through the body with casing integrated into one piece, be provided with the breach on the body, with the ratchet setting in the body, and be located breach department, the pawl passes breach and ratchet counterbalance, can enough realize the protection to the ratchet, can realize quick location with ratchet and pawl again.
