[0023] To improve or solve the technical problem in the existing technology that the rear door needs to be opened to observe the interior of the trailer, which is time-consuming and laborious, this utility model provides a semi-trailer body. The semi-trailer body includes: a trailer body; a rear door 2, which is installed on the trailer body; an opening is provided in the rear door 2, and a closed window 3 is provided at the opening; one side of the closed window 3 is hinged to the rear door 2, and a locking structure 4 is provided between the closed window 3 and the rear door 2.

[0024] Figure 1 This is a schematic diagram of an embodiment of a semi-trailer box according to this utility model. Figure 1 As shown, in one or more embodiments, the semi-trailer body of this utility model includes a body, a rear door 2, a closed window 3, and a locking structure 4.

[0025] See also Figure 1 The trailer body and the rear door 2 form a rectangular box. In one or more embodiments, one side of the rear door 2 is hinged to the trailer body, and a lock is provided between the rear door 2 and the trailer body to lock the rear door 2 onto the trailer body. The lock can be any suitable semi-trailer rear door 2 lock, and is not limited here. Furthermore, an opening is provided on the rear door 2. The opening can be located near the bottom of the rear door 2. A hinge seat 45 is provided at the opening, and one side of the closed window 3 is connected to the hinge seat 45, thereby making the closed window 3 and the rear door 2 hinged together. Specifically, the closed window 3 has a first side, a second side opposite to the first side, a third side, and a fourth side opposite to the third side. The first side is hinged to the rear door 2.

[0026] Figure 2 This is an exploded view of an embodiment of a locking structure in a semi-trailer body according to this utility model. Figure 1 and Figure 2 As shown, in one or more embodiments, the locking structure 4 includes a rotatable pivot 41 mounted on the closed window 3, a snap-fit ​​connector 42 mounted on the pivot 41, a snap-fit ​​block 43 mounted on the rear door 2, and a limiting member 44 that limits the rotation angle of the pivot 41. The pivot 41 is generally cylindrical. Specifically, sleeves 31 are provided on the second and third sides of the closed window 3. Two sleeves 31 are provided, and the two ends of the pivot 41 are rotatably arranged within the two sleeves 31. Further, the snap-fit ​​connector 42 is detachably mounted on both ends of the pivot 41. Exemplarily, the snap-fit ​​connector 42 and the pivot 41 can be detachably connected by a threaded connection structure, a snap-fit ​​structure, etc. Alternatively, the snap-fit ​​connector 42 and the pivot 41 can also be fixedly connected by a welded structure. Further, the snap-fit ​​connector 42 is generally "H"-shaped. The snap-fit ​​block 43 is fixed to the rear door 2 and matches the position of the snap-fit ​​connector 42. Specifically, the snap-fit ​​block 43 is roughly "T" shaped, so that the two arms of the snap-fit ​​connector 42 abut against the two arms of the snap-fit ​​block 43. Furthermore, a hinge seat 45 is provided on the rotating shaft 41, and the limiting member 44 forms a hinged engagement connection with the hinge seat 45.

[0027] See also Figure 1 and Figure 2In one or more embodiments, the limiting member 44 includes a limiting plate 46 mounted on the rotating shaft 41 and a limiting buckle 47 mounted on the rear door 2. The limiting plate 46 is hinged to the rotating shaft 41 and can rotate to be close to the rotating shaft 41, making the limiting plate 46 parallel to the rotating shaft 41 and preventing the limiting plate 46 from protruding excessively. Specifically, the limiting plate 46 includes a connecting portion 461 hinged to the rotating shaft 41 and an inner recess 462 recessed towards the closed window 3. The inner recess 462 is recessed towards the closed window 3 so that the limiting buckle 47 fixes the limiting plate 46 to the closed window 3. Furthermore, the limiting buckle 47 includes a first limiting seat 471 fixed to the closed window 3 and a second limiting seat 472 rotatably mounted on the closed window 3; the first limiting seat 471, the second limiting seat 472, and the closed window 3 form a limiting groove that matches the recessed portion 462, thereby fixing the limiting plate 46 to the closed window 3. Specifically, the first limiting seat 471 and the second limiting seat 472 are arranged opposite to each other. The first limiting seat 471 is fixed to the closed window 3 by a welding structure, and a groove is formed on the side near the second limiting seat 472. The second limiting seat 472 has a groove on the side near the first limiting seat 471, and the two grooves cooperate to form a limiting groove. When the limiting plate 46 is connected to the limiting buckle 47, the snap-fit ​​connector 42 and the snap-fit ​​block 43 form a snap-fit ​​connection; when the limiting plate 46 is disengaged from the limiting buckle 47, the snap-fit ​​connector 42 disengages from the snap-fit ​​block 43. Furthermore, a fixing hole is provided on the first limiting seat 471, and a fixing hole is also provided on the second limiting seat 472, thereby fixing the first limiting seat 471 and the second limiting seat 472. When it is necessary to open the closed window 3, the second limiting seat 472 is rotated so that the limiting plate 46 can rotate to disengage from the limiting groove. Then, the limiting plate 46 is pushed to rotate circumferentially along the rotating shaft 41, so that the snap-fit ​​connector 42 disengages from the snap-fit ​​block 43, and the closed window 3 can be opened.
