Description

Chair buckle Technical Field The utility model relates to the technical field of seats, in particular to a seat buckle. Background In order to make the child riding in the vehicle more stable and avoid the child from falling and being injured, various child seats are currently available on the market. Existing child seats generally require the use of a buckle to lock the harness to ensure that the child is quickly and securely retained within the seat. The current buckle mostly comprises a buckle main body and an inserting block connected with a safety belt, wherein a socket is arranged on the buckle main body, locking components such as a bayonet lock are arranged in the socket, and the inserting block is locked through the locking components after being inserted into the socket. The above-mentioned buckle that is common at present uses, but still exists following shortcoming: namely, when the buckle is locked and unlocked, the problem that the operation is inconvenient and long exists. Specifically, during the locking process, the user needs to complete a series of operations of elongating the safety belt, aligning the insert block with the socket of the buckle main body, inserting the insert block into the socket, and then fastening the insert block with the locking piece in the socket to complete the insertion action. However, due to the disturbance of the child's movement, the safety belt may be suddenly tightened when the plug is not manually pushed to be completely locked, resulting in the inserted plug being accidentally pulled out, forcing the user to repeat the operation procedure. This case not only lengthens the operation time but also increases the operation burden on the user. In the unlocking link, the user needs to keep stable control on the buckle main body and unlock the locking component to finish the unlocking action. However, the sudden movement of the child easily causes the main body of the buckle to displace, which causes the buckle to deviate from the control range of the user, thus causing the unlocking process to be interrupted and the operation to be inconvenient. Therefore, how to solve the above-mentioned drawbacks of the prior art is a subject to be studied and solved by the present utility model. Disclosure of utility model The utility model provides a seat buckle, and aims to solve the technical problems in the background art. The seat buckle comprises a buckle main body and at least two inserting blocks, wherein a fixed cavity is formed in the buckle main body, the seat buckle further comprises an unlocking piece, a locking structure and a magnetic attraction component, the unlocking piece is positioned in the buckle main body and movably penetrates through the fixed cavity, the locking structure acts on the inserting blocks and the buckle main body, in the locking state of the seat buckle, the inserting blocks extend into the fixed cavity, the extending ends of the inserting blocks are attracted with the unlocking piece through the magnetic attraction component, the inserting blocks and the buckle main body are locked through the locking structure, so that the locking of the inserting blocks and the buckle main body is achieved, and in the unlocking state of the seat buckle, the unlocking piece is released from the attraction state of the magnetic attraction component and the locking state of the locking structure through translation in the fixed cavity, so that the unlocking of the inserting blocks and the buckle main body is achieved. In the above scheme, the content is explained as follows: In the above scheme, the extending end of the insert block and the unlocking piece are attracted by the magnetic attraction component, and under the action of the magnetic attraction component, the extending end of the insert block automatically moves into the fixed cavity and forms a non-contact adsorption state with the side part of the unlocking piece, and the extending end and the unlocking piece keep a relative positioning relation of a preset distance under the constraint of a magnetic field. It should be noted that the attraction does not mean to be completely attached together, but the attraction of magnetic force leads the extending end of the insertion block and the unlocking piece to have a mutual attaching trend, namely, the precise positioning of 'to be attached and detached' is realized through the magnetic force effect, thus not only keeping physical isolation, but also ensuring reliable connection of functionality. In the above scheme, the buckle main part week side is equipped with spacing hole with unlock piece corresponding position department, sets up the socket that is used for guiding the end of stretching into of inserted block to get into fixed cavity at buckle main part week side simultaneously, and every inserted block stretches into the end and sets up with every socket one-to-one respectively. In the above scheme, the number of the sockets is preferably tw
