The number of the convex portions 73 may be set as required, and in the present embodiment, one convex portion 73 is provided at the center of the support portion 71. The protrusion 73 may facilitate the provision of the second elastic member 60.

The second elastic member 60 is disposed between the error preventing member 70 and the releasing member 40, and has one end abutting against the releasing member 40 and one end abutting against the error preventing member 70. The second elastic member 60 is disposed in a direction consistent with the insertion direction of the first locking bolt 20 and the second locking bolt 30, and is used to reset the error preventing member 70. In this embodiment, the second elastic element 60 is a spring, one end of which abuts against the connecting portion 47, and the other end of which is sleeved on the protruding portion 73 of the error preventing element 70 and abuts against the surface of the supporting portion 71.

Therefore, the safety belt buckle device of the utility model is formed, the whole assembly relation is as follows:

the releasing member 40 is installed in the buckle body 10, and one end of the releasing member 40 is pivotally connected to the buckle body 10 through a pin 80, so that the releasing member 40 can deflect in the buckle body 10 around the pin 80; a first elastic member 50 is provided between the rear wall plate portion 46 of the release 40 and the buckle body 10, and the direction of the elastic force of the first elastic member 50 is opposite to the pressing direction of the release 40; the second elastic member 60 is disposed between the releasing member 40 and the error preventing member 70, the error preventing member 70 is disposed between the blocking portion 48 and the connecting portion 47 of the releasing member 40, and the error preventing portion 72 of the error preventing member 70 faces the locking claw portion 43 of the releasing member 40; under the elastic force of the second elastic member 60, the error preventing part 72 of the error preventing member 70 can abut against the locking claw part 43; the first locking tongue 20 and the second locking tongue 30 may be put together, and an insertion end of the second locking tongue 30 may be put on the abutting portion 22 of the first locking tongue 20.

The utility model discloses a safety belt buckle device's theory of operation as follows:

when the first locking bolt 20 and the second locking bolt 30 are assembled together and are jointly inserted into the insertion cavity 42 of the release element 40, the abutting part 22 of the first locking bolt 20 contacts the supporting part 71 of the error preventing element 70 to push the error preventing element 70, at the moment, the error preventing element 70 moves towards the insertion direction, and the second elastic element 60 is compressed; when the error preventing member 70 moves in the inserting direction, the error preventing portion 72 of the error preventing member 70 moves synchronously, so that the error preventing portion 72 is withdrawn from the locking claw portion 43, at this time, the locking claw portion 43 on the inner wall of the inserting cavity 42 is not blocked, and the locking claw portion 43 can be hooked by the locking hook portion 31 of the second latch tongue 30, so that the connection state, i.e., the locked state, is maintained. When the release member 40 is not pressed, the first locking tongue 20 and the second locking tongue 30 can maintain the current state, i.e., the stable connection state;

when unlocking is needed, the front wall plate part 45 of the release piece 40 is pressed, the release piece 40 deflects around the pin shaft 80 to compress the first elastic piece 50, and the claw part 43 is separated from the hook part 31 to unhook the claw part 43 from the hook part 31; when the locking claw part 43 is unhooked from the locking hook part 31, the second elastic element 60 can push the error preventing element 70 to move towards the ejecting direction, so as to promote the first bolt 20 and the second bolt 30 to eject from the inserting cavity 42;

when the releasing piece 40 is released, under the action of the first elastic piece 50, the releasing piece 40 is reset, and the error preventing part 72 of the error preventing piece 70 is continuously abutted to the locking claw part 43 of the releasing piece 40;

when the single first latch 20 is inserted into the insertion cavity 42 of the release member 40, the first latch 20 can push the error preventing member 70 to move in the insertion direction, but the first latch 20 lacks a structure for hooking with the claw portion 43, so that the first latch 20 cannot hook the claw portion 43, and locking cannot be achieved; at this time, the first latch 20 inserted into the socket 42 is easily perceived by the user that the two are not connected, so that the user does not misunderstand that the locking is successful.

When the second latch bolt 30 alone is inserted into the insertion cavity 42 of the release member 40, since the insertion end of the second latch bolt 30 is shorter than the insertion end of the first latch bolt 20, the insertion end of the second latch bolt 30 cannot touch the support portion 71 of the error preventing member 70, and thus the error preventing member 70 cannot be pushed, so that the error preventing portion 72 abuts against the latch claw portion 43, and the latch hook portion 31 of the second latch bolt 30 cannot hook the latch claw portion 43 of the release member 40, and thus locking cannot be achieved. At this time, the second latch tongue 30 inserted into the insertion cavity 42 is easily perceived by the user that the two are not connected, so that the user does not misunderstand that the locking is successful.

For the safety belt buckle device of the present invention, only when the first locking tongue 20 and the second locking tongue 30 are inserted in place at the same time, the first locking tongue 20 and the second locking tongue 30 can be connected with the release member 40 to realize locking; a single bolt is inserted, and locking cannot be realized; therefore, the locking device can avoid misoperation of a user, avoid the phenomenon that the user is mistakenly locked when the user is not inserted in place, and greatly improve the use safety.

While the invention has been described with reference to the above embodiments, the scope of the invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the invention.
