One end of the safety hook body is rotatably connected to the side baffle, and the other end can be hung on the fixed shaft. The fixed shaft is arranged on the rear baffle. A cushion plate is arranged between the safety hook body and the side baffle. The cushion plate is fixedly connected to the side baffle. Fixing holes are simultaneously opened at corresponding positions of the cushion plate and the safety hook body. A fixing pin is inserted into the fixing hole, and a fixing clip for restricting the safety hook body from automatically disengaging from the fixed shaft is arranged on the fixing pin.

[0006] The beneficial effect of adopting the above technical solution is that after the safety hook body and the cushion plate are connected in series by the fixing pin and then the fixing clip is used to fix the fixing pin, the safety hook body is no longer affected by road bumps and the vehicle's own inertia and "pops open", so as to reduce the spilling of transported items such as gold concentrate, reduce the economic losses of enterprises, and improve the safety of road transportation at the same time.

[0007] Further, the fixing pin includes a head and a rod portion connected to each other. The diameter of the head is greater than the diameter of the fixing hole. The rod portion is inserted into the fixing hole and connected to the fixing clip.

[0008] The beneficial effect of adopting the above technical solution is that after the rod portion of the fixing pin is inserted into the fixing hole, one end is limited by the head, and the other end is fixed by the fixing clip, realizing the series connection and fixing of the fixing pin to the safety hook body and the cushion plate, so that the safety hook body is no longer affected by road bumps and the vehicle's own inertia and "pops open".

[0009] Further, an installation hole is formed in the rod portion, and the fixing clip is an R-shaped pin which is installed in the installation hole.

[0010] The beneficial effect of adopting the above technical solution is that after the R-shaped pin is installed in the installation hole of the rod portion, the fixing of the fixing pin by the R-shaped pin can be realized, and the rod portion of the fixing pin can be prevented from disengaging from the fixing hole.

[0011] Further, the R-shaped pin includes an insertion rod, a clamping rod, and a holding rod disposed between the insertion rod and the clamping rod. At least two bending points are provided on the clamping rod, and a clamping position is formed between the clamping rod portion between adjacent two bending points and the insertion rod; the insertion rod is inserted into the installation hole, so that the rod portion is located in the clamping position.

[0012] The beneficial effect of adopting the above technical solution is that by inserting the insertion rod of the R-shaped pin into the installation hole of the rod portion and making the rod portion of the fixing pin located in the clamping position formed on the R-shaped pin, the fixing of the fixing pin by the R-shaped pin can be realized.

[0013] Further, the insertion rod and the holding rod are integrally connected, and the holding rod and the clamping rod are integrally connected.

[0014] The beneficial effect of adopting the above technical solution is that the strength of the R-shaped pin can be enhanced and the breakage of the R-shaped pin can be reduced.

[0015] Further, a galvanized layer is provided on the surface of the R-shaped pin.

[0016] The beneficial effect of adopting the above technical solution is that the galvanized layer makes the R-shaped pin have an anti-corrosion effect and can extend the service life of the R-shaped pin.

[0017] Further, an anti-slip layer is provided on the surface of the rod portion.

[0018] The beneficial effect of adopting the above technical solution is that the anti-slip layer can increase the friction between the rod portion and the fixing hole, so as to reduce the movement of the rod portion of the fixing pin in the fixing hole, and further reduce the disengagement of the rod portion of the fixing pin from the fixing hole.

[0023] The following combines the attached Figures 1 - 3 Describe the principles and features of the present utility model. The examples cited are only used to explain the present utility model and are not used to limit the scope of the present utility model.

[0024] An embodiment of the present utility model discloses a safety hook structure for the rear baffle of a dump truck.

[0025] Referring to Figures 1 - 3 , a safety hook structure for the rear baffle of a dump truck includes a safety hook body 1 and a fixed shaft 2. One end of the safety hook body 1 is rotatably connected to the side baffle 3 through a pin shaft, and the other end can be hung on the fixed shaft 2. The fixed shaft 2 is installed on the rear baffle 4. A cushion plate 5 is provided between the safety hook body 1 and the side baffle 3, and the cushion plate 5 is fixedly connected to the side baffle 3. Through the fixed pin 7 and the fixed clamp, the fixing of the safety hook body 1 and the cushion plate 5 is realized, so that the safety hook body 1 is no longer affected by the bumps of the road and the inertia of the vehicle itself and "breaks open", reducing the economic losses of the enterprise and improving the safety of road transportation at the same time.

[0026] Corresponding positions of the cushion plate 5 and the safety hook body 1 are simultaneously provided with fixed holes 6. The fixed pin 7 is inserted into the fixed hole 6, and the fixed clamp is arranged on the fixed pin 7 to limit the safety hook body 1 from automatically disengaging from the fixed shaft 2. Specifically, after the safety hook body 1 and the cushion plate 5 are connected in series through the fixed pin 7, the fixed clamp is used to fix the fixed pin 7, so that the safety hook body 1 is no longer affected by the bumps of the road and the inertia of the vehicle itself and "breaks open".

[0027] The fixed pin 7 includes a head 71 and a shaft portion 72 that are integrally connected. The diameter of the head 71 is greater than the diameter of the fixed hole 6. The shaft portion 72 is inserted into the fixed hole 6 and connected to the fixed clamp, so that one end of the fixed pin 7 is limited by the head 71, and the other end is fixed by the fixed clamp, so as to realize the series connection and fixation of the fixed pin 7 to the safety hook body 1 and the cushion plate 5.

[0028] An anti-slip layer is fixedly provided on the surface of the shaft portion 72 to increase the friction between the shaft portion 72 and the fixed hole 6, reduce the movement of the shaft portion 72 of the fixed pin 7 in the fixed hole 6, and further reduce the shaft portion 72 of the fixed pin 7 from disengaging from the fixed hole 6.

[0029] The rod portion 72 is provided with a mounting hole 8, the fixing clip is an R-shaped pin 9, and the R-shaped pin 9 is installed in the mounting hole 8 to fix the fixing pin 7 by the R-shaped pin 9 and prevent the rod portion 72 of the fixing pin 7 from disengaging from the fixing hole 6.

[0030] The R-shaped pin 9 includes an insertion rod 91, a clamping rod 92, and a holding rod 93 disposed between the insertion rod 91 and the clamping rod 92. At least two bending points 10 are provided on the clamping rod 92. In this embodiment, two bending points are provided. A clamping position 11 is formed between the portion of the clamping rod 92 between the two bending points 10 and the insertion rod 91; the insertion rod 91 of the R-shaped pin 9 is inserted into the mounting hole 8 of the rod portion 72, so that the rod portion 72 of the fixing pin 7 is located within the clamping position 11, and thus the fixing of the fixing pin 7 by the R-shaped pin 9 can be achieved.

[0031] A galvanized layer is fixedly provided on the surface of the R-shaped pin 9, so that the R-shaped pin 9 has an anti-corrosion effect and can extend the service life of the R-shaped pin 9. The insertion rod 91 and the holding rod 93 are integrally connected, and the holding rod 93 and the clamping rod 92 are integrally connected, which can enhance the strength of the R-shaped pin 9 and reduce the breakage of the R-shaped pin 9.
