[0005] In view of the fact that most flatbed semi-trailer trailers on the market do not have a leak-proof mechanism when transporting goods, which causes the goods to fall off the trailer during transportation and affects the use of the flatbed semi-trailer trailer, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a flatbed semi-trailer body with a bottom-leaking prevention mechanism.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flatbed semi-trailer body with a bottom-leaking mechanism, including a semi-trailer body body, which includes a fixing plate. A fixing plate is installed on the side wall of one end of the semi-trailer body body. Wheel bodies are installed at the bottom of the semi-trailer body body. First baffles are hinged to both sides of the top of the semi-trailer body body.

[0014] As a preferred embodiment of the flatbed semi-trailer body with a bottom-leaking prevention mechanism of the present invention, wherein the threaded rod is threadedly connected to the first threaded hole and the second threaded hole respectively.

[0015] As a preferred embodiment of the flatbed semi-trailer body with a bottom-leaking prevention mechanism of the present invention, there are two sets of the first baffle with the same structure.

[0016] The flatbed semi-trailer with a bottom-leaking prevention mechanism of this utility model has the following beneficial effects:

[0017] 1. This utility model firstly uses an arc-shaped groove and a limiting plate to cooperate with each other, and the limiting groove is hinged to the semi-trailer body. This allows the first baffle to rotate inside the arc-shaped groove through the limiting plate, so that the first baffle rotates and stands upright at the top of the semi-trailer body. At the same time, the threaded rod is threadedly connected to the second threaded hole and the first threaded hole respectively. This makes it easy to rotate the handle body to drive the threaded rod to rotate and connect it to the second threaded hole, thus facilitating the positioning and fixing of the first baffle.

[0018] 2. This utility model firstly utilizes the cooperation between the slide rail and the slider. By pulling the limiting rod, the disc body is driven to rise and fall within the slide rail via the slider, causing the first spring body to deform. Simultaneously, the second baffle is hinged to the semi-trailer body and engages with the limiting groove via the limiting rod. The elastic recovery of the first spring body causes the limiting rod to engage with the limiting groove, thus facilitating the positioning and fixing of the second baffle. Therefore, the second baffle and the first baffle provide better leak-proof protection for the semi-trailer body when transporting goods. Attached Figure Description
