Safety belt buckle structure

Abstract

The invention provides a safety belt buckle structure comprising a receptacle body having at least four holes, at least four insert teeth, and a locking mechanism disposed in the receptacle body. The insert teeth are in one-to-one correspondence with the holes. The insert teeth and the holes can be locked or unlocked; when the insert teeth and the holes are locked, the insert teeth are inserted into the holes and respectively independently locked and connected to the locking mechanism in a one-to-one correspondence manner; when the insert teeth and the holes are unlocked, the insert teeth are separated and unlocked from the locking mechanism at the same time and leave the holes. The receptacle body is further provided with an unlocking button which drives the locking mechanism to simultaneously separate from the insert teeth. The insert teeth in the safety belt buckle structure are all in one-to-one correspondence with the holes and independently connected and locked to the locking mechanism, safety and reliability are better, all insert teeth can be unlocked just by pressing the unlocking button, and operation is quite facilitated.

Description

technical field [0001] The invention relates to a safety belt buckle structure. Background technique [0002] Seat belt buckles are widely used in baby carriages and child car safety seats to connect and lock safety belts to prevent babies from falling from the baby carriage or safety seat. In the prior art, there is a safety belt buckle disclosed in Chinese patent CN201480194U, which includes a socket with a first jack and a second jack on the left and right sides, and a first plug that can be inserted into the first jack. 1. A second plug that can be inserted into the second jack, a first locking mechanism is provided between the first plug and the socket, a second locking mechanism is provided between the second plug and the socket, and it also includes simultaneously driving the first locking mechanism. The button for unlocking the mechanism and the second locking mechanism can release the first plug and the second plug at the same time when the button is pressed. Howe...

AI Technical Summary

Problems solved by technology

The seat belt buckle structure with this structure has the following problems: when four seat belts are connected through four joints, it needs to be combined and joined together to form a composite joint that is locked and unlocked at the same time. When one of the joints that constitute the composite joint fails, the other must fail

The seat belt connection buckle with this structure has the following problems: a set of locking plug and idle plug is inserted into the insertion space of the socket at the same time, and the locking plug is locked with the locking mechanism and blocked by the blocking part of the locking plug. The idle plug withdraws to achieve the locking effect of the idle plug. When the locking plug is not locked with the locking mechanism, the idle plug cannot be locked. When the blocking part of the locking plug is worn or broken, the idle plug cannot be locked in the insertion space. , it is easy to withdraw from the socket and make the lock invalid, causing a safety hazard
