The invention discloses a loose-proof latch hook structure for rear seats of MPV (Multi-Purpose Vehicle) commercial vehicles, and relates to the rear seats of the MPV commercial vehicles. The loose-proof latch hook structure comprises a seat locking rod, a seat supporting leg, a seat latch hook, a latch hook pin, a latch hook tension spring and a tension spring hitch pin. The seat supporting leg comprises a seat supporting leg body, and two lateral plates which are connected with the seat supporting leg body. The bottom parts of the lateral plates are provided with clamp grooves. The seat latch hook comprises a latch hook body, and a hanging hook which is formed in a manner of extending the lower part of the latch hook body downwards and then backwards. The inner lateral side of the hanging hook is a smooth circular curved surface, and the seat latch hook is rotationally connected between the two lateral plates of the seat support leg through the latch hook pin. According to the loose-proof latch hook structure, the inner lateral side of the hanging hook is the smooth circular curved surface, the seat locking rod is in contact with any part of the circular curved surface of the hanging hook, and the seat supporting leg is synchronously locked through a left latch hook and a right latch hook under the condition of installation size biases, so that a non-synchronous locking phenomenon is avoided, thus abnormal collision sound is prevented when the seats are installed on the vehicles.
Description
technical field [0001] The invention relates to a rear seat of a commercial vehicle, in particular to a rear seat anti-loosening lock hook structure. Background technique [0002] In existing commercial vehicles, the rear seats are generally designed to be movable in order to carry people or store goods conveniently, that is, the locking devices of the rear seats can be unlocked according to the needs of storage, and the rear seats can be locked at the same time. Fold to expand storage space. Generally, there are two locking devices for the rear seats, which are respectively located on the left and right sides of the rear seats. When the locking hook of the locking device in the prior art is locked, it is possible that due to assembly errors or other reasons, the locking of the two locking hooks may not be synchronized. Noise, especially when the vehicle is running on a bumpy road, greatly reduces the safety and comfort of the vehicle. Contents of the invention [0003]...
