Description

Technical Field

[0001] The utility model relates to the technical field of dump truck side locks, in particular to a dump truck side lock hook. Background Art

[0002] The side lock hook is an important mechanical component specially designed for the side panels of dump trucks or other tipping devices. Its main function is to fix and lock the side panels or tailgate of the vehicle compartment to prevent accidental spillage of goods during transportation and ensure the safety of vehicle operation. When the goods need to be unloaded, the side lock hook can be operated to unlock the side panels or tailgate of the vehicle compartment and open it to complete the unloading operation.

[0003] In order to keep the side lock hook locked with the pin shaft and prevent it from bouncing away, the conventional side lock hook and the pin shaft are too tight during welding and positioning. Therefore, during use, it is necessary to use external tools, such as a hammer, to knock the lock hook plate to engage the pin shaft, which is inconvenient to operate. In addition, after use and wear, the side lock hook and the pin shaft will easily bounce away or make abnormal noises due to the large gap when the vehicle runs on bumpy roads. When the side lock hook loses its function, it has a huge impact on the rear door panel and the rear lock hook device of the vehicle, which can easily cause the rear door panel and the rear lock hook to deform, crack, or even break.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, Figure 1-Figure 3 When the locking nut 303 is unlocked, the cam 302 is unlocked and the locking nut 303 is unlocked, so that the cam 302 and the locking nut 303 can be unlocked.

[0028] In one embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the fixing assembly includes a limiting column 401, one end of which is provided with a thread, and the end of the limiting column 401 with the thread is threadedly connected to the inside of the anti-jump board 100, and the outer surface of the other end of the limiting column 401 is rotatably connected to the inside of the lock hook plate 200, and the outer surface of the limiting column 401 away from the anti-jump board 100 is also fixedly connected to the limiting plate 402, and the limiting plate 402 is slidably connected to the limiting rod 403 inside the end away from the limiting column 401. Limiting holes 404 are provided on both ends of the lock hook plate 200 on the side away from the anti-jump board 100, and the limiting rod 403 is slidably connected to the inside of the limiting hole 404. By inserting the limiting column 401 into the inside of the lock hook plate 200, when it contacts the anti-jump board 100, the limiting column 401 can be rotated to reach the inside of the anti-jump board 100, thereby driving the limiting rod 403 to reach the limiting hole, thereby limiting and fixing the lock hook plate 200.

[0029] In one embodiment, Figure 2As shown, the limiting ball 302 is an elastic steel ball, which adds additional elastic support and stabilizing force, providing a more stable locking effect when the vehicle vibrates or the side panel is under load.

[0030] In one embodiment, Figure 1 and Figure 2 As shown, the end of the locking screw 303 away from the sliding groove 301 is hexagonal, which is convenient for rotating the locking screw 303.

[0031] In one embodiment, Figure 3 As shown, a pull ring 500 is provided on one end of the limiting rod 403 away from the limiting hole 404 to facilitate pulling the limiting rod 403 .

[0032] In one embodiment, Figure 3 As shown, the diameters at both ends of the limiting rod 403 are larger than the diameter in the middle portion, thereby increasing the limiting effect.

[0033] In one embodiment, Figure 3 As shown, a second spring 600 is provided between the limiting plate 402 and the lock hook plate 200 , and the second spring 600 is sleeved on the limiting rod 403 so as to limit the limiting rod 403 .

[0034] In one embodiment, Figure 1 and Figure 3 As shown, the two limiting holes 404 are adapted to the shape and specifications of one end of the limiting rod 403 , so that the limiting rod 403 can reach into the limiting hole 404 .

[0035] In one embodiment, Figure 2 As shown, the diameter of the sliding groove 301 at the end away from the locking screw 303 is smaller than the diameter at the end close to the locking screw 303, so that it can limit the limiting ball 302.

[0036] The above embodiment discloses a side lock hook of a dump truck, wherein the lock hook plate 200 is abutted against the anti-jump plate 100, and the limiting column 401 is inserted into the inside of the lock hook plate 200. When it contacts the anti-jump plate 100, the limiting column 401 can be rotated to reach the inside of the anti-jump plate 100, and then the pull ring 500 is pulled to drive the limiting rod 403 to move and squeeze the second spring 600. As the limiting column 401 rotates, the limiting plate 402 and the limiting rod 403 are driven to rotate, and then the tension on the limiting rod 403 is released. Then, under the elastic force of the second spring 600, it reaches the limiting hole 404, thereby limiting and fixing the lock hook plate 200, and then the limiting ball 302 is placed in the slide groove 301, and then the first spring 304 is placed, and finally the locking screw 303 is placed, and then the locking screw 303 is rotated to limit the limiting ball 302 and the first spring 304.
