[0019] Please refer to Figure 2 , in the embodiment of the present utility model, a platform box with a foldable cargo retaining plate is disclosed. A common platform box includes a chassis 1, a front beam body 2 and a rear beam body 3. The chassis 1 is a steel floor or a wooden floor. The front beam body 2 and the rear beam body 3 are respectively arranged on both sides of the chassis 1 along the length direction. When transporting the platform box, the front beam body 2 is generally placed close to the cab of the semi-trailer. Plug-in slots and lashing rope loops are still reserved on both sides of the chassis 1 in the width direction for loading requirements.

[0020] The platform box in the present utility model further includes a cargo baffle 4. The cargo baffle 4 includes a blocking frame 41 and a support frame 42 which are rotatably connected. The support frame 42 is welded to the front end beam body 2. The support frame 42 and the blocking frame 41 are connected by at least one hinge 43. The two hinges of the hinge 43 are respectively fixed to the support frame 42 and the blocking frame 41. The hinge 43 between the blocking frame 41 and the support frame 42 can be correspondingly arranged according to the actual frame structure. Only a common frame structure and the number of hinges 43 are shown in this embodiment.

[0021] Refer to Figure 3 and Figure 4 , the blocking frame 41 is a set of square tube components with three rows and three columns, and the support frame 42 is a set of square tube components with one row and three columns. The columnar square tubes of the blocking frame 41 and the support frame 42 correspond to each other, and a hinge 43 is provided at the corresponding position of each columnar square tube:

[0022] The blocking frame 41 includes a first square tube 411, a second square tube 412, a third square tube 413 and a fourth square tube 414 in the same plane. The first square tube 411, the second square tube 412 and the third square tube 413 are the row-direction square tubes of the blocking frame 41, and the fourth square tube 414 is the column-direction square tube of the blocking frame 41. The three fourth square tubes 414 are evenly distributed between the first square tube 411 and the third square tube 413. The two ends of the fourth square tube 414 are respectively welded to the first square tube 411 and the third square tube 413. A second square tube 412 is provided between two adjacent fourth square tubes 414, and the two ends of the second square tube 412 are respectively welded to the middle parts of the two fourth square tubes 414.

[0023] The support frame 42 includes a fifth square tube 421 and a sixth square tube 422 in the same plane. The fifth square tube 421 is the row-direction square tube, and the sixth square tube 422 is the column-direction square tube. The two ends of the sixth square tube 422 are respectively welded to the fifth square tube 421 and the front end beam body 2, and the two ends of the fifth square tube 421 are also welded to the front end beam body 2. The distance between the sixth square tubes 422 is equal to the distance between the fourth square tubes 414.

[0024] The third-party pipe 413 and the fifth-party pipe 421 are connected by three hinge joints 43. The two hinges of the hinge joint 43 are respectively welded face to face to the third-party pipe 413 and the fifth-party pipe 421. The welding points of the fourth-party pipe 414 on the third-party pipe 413 and the welding points of the sixth-party pipe 422 on the fifth-party pipe 421 correspond one by one. The hinge joint 43 is arranged between each pair of welding points and is supported by the column-direction pipes and the row-direction pipes at the same time, enhancing the service life of the hinge joint 43. The position of the hinge joint 43 is on the side of the cargo baffle 4 facing the chassis 1. According to the structure of the hinge joint 43 and the pipes, the blocking frame 41 can only flexibly rotate within the range perpendicular to the support frame 42 to the same plane as the support frame 42. When the blocking frame 41 is perpendicular to the support frame 42, the cargo baffle 4 is folded. When the blocking frame 41 is in the same plane as the support frame 42, the cargo baffle 4 is enabled.

[0025] Refer to Figure 5 and Figure 6 , in order to ensure that when the cargo baffle 4 is folded, it does not affect the use of the chassis 1, a groove 11 is opened on one side of the chassis 1 close to the front beam 2. The shape of the groove 11 matches the shape of the blocking frame 41, and the depth of the groove 11 is at least equal to the thickness of the blocking frame 41. The non-groove 11 part at this place still retains part of the structure of the chassis 1, so that the design of the groove 11 does not affect the loading of goods here. When the blocking frame 41 is perpendicular to the support frame 42, it can be completely placed in the groove 11, that is, the blocking frame 41 is received in the chassis 1, and the upper surface of the blocking frame 41 is flush with the surface of the chassis 1, thus facilitating the loading of goods or stacking in the platform box.

[0026] Combined with Figure 3 and Figure 4 , a movable bolt 44 is arranged inside the blocking frame 41, and a corresponding bolt hole 423 is opened on the support frame 42. If it is necessary to enable the cargo baffle 4, the bolt 44 can be moved into the bolt hole 423 to lock the blocking frame 41. According to the above frame structure, mounting holes 415 are opened on both opposite plates of the third-party pipe 413. The bolt 44 is inserted into the two mounting holes 415 and can axially move within the mounting holes 415 and then penetrate through the third-party pipe 413. The bolt 44 and its moving direction are perpendicular to the third-party pipe 413, and the distance between the second-party pipe 412 and the third-party pipe 413, that is Figure 3 the distance indicated by the red double-headed arrow in

[0027] Pin holes 423 are formed in two opposite plates of the fifth square tube 421, and the positions of the pin holes 423 correspond to the mounting holes 415. When the cargo baffle 4 is enabled, the pin 44 in the mounting hole 415 naturally falls into the pin hole 423 under the influence of gravity, and at the same time penetrates the third square tube 413 and the fifth square tube 421, thereby locking the blocking frame 41 and the support frame 42. After the blocking frame 41 is locked to the support frame 42, the blocking frame 41 protrudes from the surface of the chassis 1, so as to realize the function of blocking goods. To further stabilize the locking structure, mounting holes 415 and pins 44 are provided at both the left and right sides in the middle of the third square tube 413. The two mounting holes 415 are symmetric about the fourth square tube 414 in the middle, and at the same time, the fifth square tube 421 is correspondingly provided with two pin holes 423.

[0028] If it is not necessary to use the cargo baffle 4, or when the platform box needs to be stacked and placed in the yard, only need to lift the pin 44 upward to fold the blocking frame 41. On the one hand, it solves the storage problem of the cargo baffle 4, and on the other hand, it will not affect the stacking of the platform box due to the existence of the cargo baffle 4.

[0029] In summary, the present utility model designs the cargo baffle 4 to be foldable, and uses the gravity of the pin 44 to prevent the cargo baffle 4 from folding during use. At the same time, only by lifting the pin 44 can it be folded, so that the blocking frame 41 is recessed into the chassis 1; the foldable cargo baffle 4 is safer and more reliable, which not only improves the safety guarantee during transportation, but also avoids the problems of difficult storage and loss of the cargo baffle 4.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
