For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0035] The utility model will be further described below in combination with the drawings:

[0036] Embodiment 1: as Figures 4 to 6 The utility model embodiment provides a self-unloading vehicle rear door compression mechanism, including zip fastener 3, compression block 4 and compression block support plate 5, wherein zip fastener 3 one end is connected with chassis girder 7, the other end is hinged with compression block 4, compression block 4 is hinged on the bottom plate of the carriage 8 of self-unloading vehicle through compression block support plate 5, and is compressed at the lower end of the rear door 9 of self-unloading vehicle.

[0037] Specifically, in the embodiment 1, as Figures 7 to 12 The utility model embodiment provides a self-unloading vehicle rear door compression mechanism, including zip fastener 3, compression block 4 and compression block support plate 5, wherein zip fastener 3 one end is connected with chassis girder 7, the other end is hinged with compression block 4, compression block 4 is hinged on the bottom plate of the carriage 8 of self-unloading vehicle through compression block support plate 5, and is compressed at the lower end of the rear door 9 of self-unloading vehicle.

[0038] More specifically, in the embodiment 1, as Figure 7 The utility model embodiment provides a self-unloading vehicle rear door compression mechanism, including zip fastener 3, compression block 4 and compression block support plate 5, wherein zip fastener 3 one end is connected with chassis girder 7, the other end is hinged with compression block 4, compression block 4 is hinged on the bottom plate of the carriage 8 of self-unloading vehicle through compression block support plate 5, and is compressed at the lower end of the rear door 9 of self-unloading vehicle.

[0039] In this embodiment 1, when the carriage 8 is lifted, the distance between the clamping block support plate 5 and the chassis beam 7 will become shorter, the zipper 3 will become loose, and the clamping block 4 will flip backward under the action of gravity, thereby opening the rear door 9.

[0040] Example 2: Figures 4 to 6 As shown, Embodiment 2 is an improvement on Embodiment 1 described above. The improvement lies in that the dump truck rear door clamping mechanism further includes a zipper seat 1 and an adjusting rod 2. The zipper seat 1 is connected (e.g., welded) to the chassis beam 7, and one end of the adjusting rod 2 is screwed to the zipper seat 1, while the other end is hinged to the zipper 3. By setting the zipper seat 1 and the adjusting rod 2, it is easy to hinge the zipper 3, thus avoiding the zipper 3 from being too long.

[0041] Example 3: As Figures 7 to 12 As shown, this embodiment 3 is an improvement on the basis of the above embodiment 1 or 2. The improvement is that the pressing block 4 also includes several pads 405, and each side support plate 402 and zipper support plate 403 are respectively connected to the pressing plate 401 through a pad 405 (e.g., welding).

[0042] Example 4: Figure 13 and 14 As shown, this embodiment 4 is an improvement based on the above-described embodiments 1, 2, or 3. The improvement lies in that the clamping block 4 further includes at least one central support plate 404, one end of which is connected to the clamping plate 401, and the other end is hinged to the floor of the carriage 8 via the clamping block support plate 5 and the pin 6. The central support plate 404 further clamps the rear door 9, thereby further reducing the risk of deformation of the rear door 9. The structure of the central support plate 404 is the same as that of the side support plate 402.

[0043] Example 5: Figure 13 and 14 As shown, this embodiment 5 is an improvement on the above embodiment 4. The improvement is that the pressing block 4 also includes several pads 405. Each side support plate 402, zipper support plate 403 and middle support plate 404 are respectively connected to the pressing plate 401 through a pad 405 (e.g., welding).

[0044] Example 6: As Figure 8 , Figure 9 , Figure 11 and Figure 12As shown, the embodiment 6 is improved on the basis of the above-mentioned embodiments 1-5, and the improvement is that each zipper support plate 403 is provided with a hinge point 406 near the middle of the side close to the pressing plate 401, and the hinge point 406 is hinged with the zipper 3. Through the setting of the hinge point 406, the zipper 3 is facilitated to be installed.

[0045] The working principle of the self-unloading vehicle rear door pressing mechanism is as follows:

[0046] Transportation stage: when the rear door 9 is closed, the pressing block support plate 5 and the carriage 8 will be in a synchronous flat state, and the pressing block 4 will rotate upward around the pin 6 on the pressing block support plate 5 under the action of the zipper 3, thereby pressing the rear door 9.

[0047] Unloading stage: when the carriage 8 is lifted, the distance between the pressing block support plate 5 and the zipper seat 1 will be shortened, the zipper 3 will become loose, and the pressing block 4 will no longer be pulled tight through the hinge point 406. At this time, the pressing block 4 will be flipped backward under the action of gravity, thereby opening the rear door 9 and unloading.

[0048] Finally, it should be explained that the above-mentioned is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process transformation by using the content of the utility model specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection range of the utility model.
