However, the use scenario of the device is limited, and when the fork contacts the cargo, it is difficult for the forklift driver to feel the position of the fork, causing the fork to continue to move, increasing damage to the cargo.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Please see Figures 1 to 4 The utility model is a spring anti-collision fork, which includes a fork body 1, contact plates 2 located at both ends of the fork body 1, a buffer part 3 connecting the contact plate 2 and the fork body 1, and a wireless transmitter 4 installed on one side of the buffer part 3.

[0026] Please see Figure 1 The fork body 1 is in a horizontal state, and its two sides are bent vertically downward to fix the buffer part 3 and the wireless transmitter 4. The end of the fork body 1 extends outward to facilitate the fork body 1 to scoop up the goods.

[0027] Please see Figure 1 to Figure 2 The contact plate 2 is located at the outer side of the end of the fork body 1, and is recessed inward from the lower surface to form an air avoidance groove 21. The height of the air avoidance groove 21 is greater than the height of the fork body 1. When the contact plate 2 moves toward the fork body 1, the fork body 1 can extend into the air avoidance groove 21 to prevent the contact plate 2 from colliding with the fork body 1. Secondly, the contact plate 2 is recessed inward from its outer surface to form a receiving groove 22. The receiving groove 22 is located at both ends of the contact plate 2 and is used to receive a fixing member 23 connecting the contact plate 2 and the buffer part 3. The fixing member 23 is a bolt or a screw. The top of the fixing member 23 is lower than the surface of the contact plate 2 to prevent the fixing member 23 from first contacting an obstacle before the contact plate 2.

[0028] Please see Figure 1 and Figure 3The buffer part 3 includes a pair of fixed blocks 31 fixed to the side of the fork body 1, a transmission shaft 32 respectively penetrating the fixed blocks 31, an elastic member 33 sleeved on the transmission shaft 32, and a buffer shock absorbing member 34. The fixed block 31 is inverted L-shaped and is located on both sides of the fork body 1. The bottom and top of the fixed block 31 are fixedly connected to the fork body 1 by fixing bolts. The transmission shaft 32 is horizontally installed in the fixed block 31, and one end of the transmission shaft 32 extends to the inner side of the contact plate 2. The fixed member 23 penetrates the contact plate 2 from the outer side of the contact plate 2 and is fixedly connected to the transmission shaft 32. The other end of the transmission shaft 32 is connected to the buffer shock absorbing member 34. In this embodiment, the buffer shock absorbing member 34 is installed on any one of the transmission shafts 32. The two ends of the elastic member 33 respectively abut against the inner surface of the contact plate 2 and the side of the fixed block 31 opposite to the contact plate 2.

[0029] Please see Figure 1 and Figure 4 The buffer and shock-absorbing member 34 includes an outer cylinder 341 screwed to the transmission shaft 32, a sensing part 342 installed in the outer cylinder 341, and a buffer member 343. The outer cylinder 341 is in a horizontal state and moves synchronously with the transmission shaft 32. A cavity 344 is formed inside the outer cylinder 341. The sensing part 342 is movably installed in 344 and can move axially along the cavity 344 and be restricted by the outer cylinder 341 to avoid falling from the cavity 344. One end of the sensing part 342 penetrates the outer cylinder 341 and extends toward the wireless transmitter 4. The buffer member 343 is made of elastic material, such as a spring, an elastic colloid, etc. The two ends of the buffer member 343 respectively abut the end of the transmission shaft 32 and the end of the sensing part 342 opposite to the transmission shaft 32, so as to absorb the impact force generated by the collision of the sensing part 342.

[0030] Please see Figure 1 The wireless transmitter 4 is fixed to any side of the fork body 1 and is arranged opposite to the buffer shock absorbing member 34. The end of the wireless transmitter 4 opposite to the buffer shock absorbing member 34 has a sensing area 41. The sensing area 41 and the sensing part 342 are on the same horizontal line. The sensing area 41 is used to detect the position of the sensing part 342 and transmit the position information to the operator or the alarm system through the wireless transmitter 4.

[0031] When the spring anti-collision cargo fork of the utility model is used, the cargo fork body 1 scoops up cargo, the contact plate 2 first hits the obstacle, the transmission shaft 32 and the buffer shock-absorbing member 34 move synchronously toward the direction of the wireless transmitter 4, the sensing portion 342 moves into the sensing area 41, the sensing area 41 detects the position of the sensing portion 342 and transmits the position information to the operator or the alarm system through the wireless transmitter 4, prompting the contact plate 2 to have hit the obstacle, stopping the continuous movement of the cargo fork body 1, and avoiding damage to the cargo fork body 1 or the obstacle; when the transmission shaft 32 moves a large distance, the sensing portion 342 hits the sensing area 41, the outer cylinder 341 squeezes the buffer member 343, the transmission shaft 32 can continue to move toward the direction of the wireless transmitter 4 for a distance, avoiding damage to the wireless transmitter 4 due to excessive force, and then the contact plate 2 is separated from the contact with the obstacle, and the elastic member 33 drives the contact plate 2 to reset by its elasticity.

[0032] The utility model is a spring anti-collision cargo fork with the characteristics of wide adaptability and timely warning. The contact plate drives the transmission shaft to move in the direction of the wireless transmitter. After the wireless transmitter detects the position of the transmission shaft, the position information is transmitted to the operator or the alarm system to achieve the effect of timely warning. At the same time, the buffer shock-absorbing component prevents the wireless transmitter from being damaged by excessive force, thereby improving durability and increasing adaptability.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
