Safety belt buckle

摘要

A safety belt buckle includes a buckle member, a hook, a stop member, and a latch member. The buckle member has a chamber therein, which is communicated with an opening. The latch member has a tongue plate which is inserted into the chamber through the opening. The stop member and the hook are provided in the chamber, and the latch member is not able to be detached from the buckle member because that the stop member stops the hook from moving to engage the tongue plate. By pressing a press button on the stop member, the stop member is moved to a predetermined position, and no longer stops the hook from disengaging the tongue plate. The latch member is able to be detached from the buckle member at this time.

1. A safety belt buckle, comprising:
a buckle member having a chamber therein and an opening, wherein the opening is communicated with the chamber; a hook provided in the chamber of the buckle member to be moved between a first position and a second position, wherein the hook has a contact portion exposed out of the buckle member, the hook stays at the first position without being touched from the outside of the buckle member; a stop member provided in the chamber of the buckle member to be moved between a third position and a fourth position, wherein the stop member comprises a press button which has a bearing face outside the buckle member, and when the stop member stays at the third position, a part of the stop member is on a moving trace of the hook to stop the hook from being moved to the second position from the first position, wherein the stop member allows the hook to be moved when staying at the fourth position, wherein the third position and the fourth position are distinct from the first position and the second position, and the stop member stays at the third position without being touched from the outside of the buckle member; and a latch member having a tongue plate to be inserted into the chamber of the buckle member through the opening, wherein the hook engages the tongue plate to let the latch member unable to be detached from the buckle member when the hook is stays at the first position, wherein the hook disengages the tongue plate when staying at the second position; whereby, by pressing the bearing face of the press button, the stop member is moved backward to the fourth position from the third position, and by exerting a force onto the contact portion, therefore the hook can be moved to the second position, which allows the tongue plate to be disengaged from the hook, so that the buckle member is detached from the buckle member.
