The device includes a forklift fork, a holding component located at the front end of the forklift fork, and an induction component fixedly connected to the forklift fork. The holding component includes a holding block and transmission rods fixedly connected on both sides of the holding block. After the holding block contacts an obstacle, the transmission rods move towards the induction component, and the induction component senses a baffle at the end of the transmission rod to judge the distance between the forklift fork and the obstacle and stop the movement of the forklift fork. However, the induction method of this device is easily affected by the environment, such as unstable magnetic field and current of the induction component, resulting in the induction component not being able to sense the transmission rod in time.

The number of the plurality of limit members 13 and the plurality of rollers 14 is changed according to requirements to ensure the movement direction of the fork body 1.

[0030] Please refer to Figures 2 to 3 , the baffle 2 includes a contact portion 21 and a transmission portion 23 connecting the contact portion 21. The contact portion 21 is located outside the end of the fork body 1 and maintains a certain distance from the fork body 1. One end of the transmission portion 23 is fixedly connected to the contact portion 21, and the other end extends towards the fork body 1. The length of the contact portion 21 is greater than the width of the fork body 1, and the transmission portion 23 is located outside the side plates 11.

[0031] A slider 24 is fixedly installed on the inner side of the transmission part 23, and the slider 24 is movably connected to the slide rail 12, that is, the baffle 2 can move along the slide rail 12 through the slider 24. A return spring 25 is also provided on the inner side of the transmission part 23. The return spring 25 is fixedly connected to the transmission part 23, and the other end is fixedly connected to the fork body 1. The baffle 2 can move along the slide rail 12 toward the micro switch 3 through the slider 24, stretching the return spring 25. When the baffle 2 loses pressure, the return spring 25 pushes the baffle 2 along the slide rail 12 to move in the opposite direction of the micro switch 3 through its elastic force.

[0032] The top of the transmission part 23 extends toward the micro switch 3 to form a toggle part 26 , which is located higher than the micro switch 3 , and a slope 27 is formed on its lower surface. The slope 27 is formed by the end of the transmission part 23 extending obliquely downward toward the transmission part 23 .

[0033] Please see Figure 4 The micro switch 3 includes a sensing device 31 and a control unit 32 installed on the sensing device 31. The sensing device 31 is fixed to the outer surface of the side 11. The sensing device 31 is a certain voltage sensor that can detect changes in current or resistance of the micro switch 3. A fulcrum 33 is formed on the top of the sensing device 31. The fulcrum 33 extends outward from the top of the sensing device 31. The middle position of the control unit 32 is movably connected to the fulcrum 33. One end of the control unit 32 extends along the top of the sensing device 31 and the end is bent vertically downward to be conductive with the sensing device 31. The other end of the control unit 32 extends toward the toggle portion 26 and a roller 34 is provided at the end. The roller 34 is installed at the top of the end of the control unit 32 extending toward the toggle portion 26. When the toggle portion 26 presses the roller 34, the other end of the control unit 32 is connected to the sensing device 31, and the sensing device 31 transmits information to the wireless module 4.

[0034] The wireless module 4 is provided on one side of the micro switch 3, which is used to receive the transmission information sent by the sensing device 31 and send a warning to the control system (not shown). After receiving the warning, the control system cuts off the power and the fork body 1 stops moving.

[0035] Furthermore, a protection box 5 is provided outside the micro switch 3 and the wireless module 4 .

[0036] When the forklift fork with an anti-collision device of the present utility model is in use, the forklift fork body 1 scoops up goods. The baffle 2 first contacts an obstacle, and the baffle 2 moves along the slide rail 12 towards the microswitch 3, stretching the return spring 25. The transmission part 23 presses the roller 34. The other end of the control part 32 is connected to the sensing device 31. The sensing device 31 transmits information to the wireless module 4. The wireless module 4 receives the transmitted information sent by the sensing device 31 and issues a warning to the control system. After receiving the warning, the control system cuts off the power, and the forklift fork body 1 stops moving. After the baffle 2 disengages from the contact with the obstacle, the return spring 25 pushes the baffle 2 to move along the slide rail 12 in the direction opposite to the microswitch 3 through its elastic force, and the baffle 2 returns to its original position.

[0037] The present utility model relates to a forklift fork with an anti-collision device, which has the characteristic of rapid response. The baffle that first contacts the obstacle presses one end of the control part through the transmission part. The other end of the control part is connected to the sensing device. The sensing device transmits information to the wireless module. The wireless module receives the transmitted information sent by the sensing device and issues a warning to the control system. After receiving the warning, the control system cuts off the power to achieve the purpose of quickly stopping the movement of the forklift fork.

[0038] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
