[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0027] See also Figures 1 to 5As shown, the utility model provides an electric forklift to prevent cargo from falling, including a vehicle body 1, a fork 2, a pressure block 3, a push assembly 4, a stopper 5 and a connecting rod assembly 6. The vehicle body 1 is a prior art, which is used to drive the fork 2 to move up and down and move the cargo on the fork 2 to a designated position, which will not be described in detail here. There are two forks 2, which are arranged at intervals on the front side of the vehicle body 1 to lift cargo. There are two pressure blocks 3, which are respectively arranged on the top surfaces of the two forks 2. A through groove 21 is respectively opened on the bottom surface of each fork 2. The length direction of the through groove 21 is parallel to the length direction of the fork 2. The pushing assembly 4 is arranged in the through groove 21, and is used to push the pressure block 3 away from the top surface of the fork 2 from bottom to top, that is, the pushing assembly 4 is used to suspend the pressure block 3 above the fork 2. The stopper 5 is vertically penetrated through the end of the fork 2 away from the vehicle body 1. In the absence of external force, the upper end of the stopper 5 is flush with the top surface of the fork 2 to prevent the stopper 5 from affecting the fork 2 from lifting the goods. A connecting rod assembly 6 is provided between the lower part of the stopper 5 and the pushing assembly 4, which is used to drive the stopper 5 to move above the top surface of the fork 2, so that the stopper 5 blocks the goods on the top surface of the fork 2.

[0028] During implementation, the vehicle body 1 drives the fork 2 to move under the cargo. It should be noted that a plug plate is mostly provided under the cargo to facilitate forking the cargo. Of course, the staff can also directly place the cargo on the fork 2 without limitation. In the process of inserting the fork 2 into the plug plate, without the action of external force, the top of the block 5 is flush with the top surface of the fork 2, and the pressure block 3 is slightly higher than the top surface of the fork 2. In actual operation, there is enough space under the plug plate to insert the fork 2, that is, even if the pressure block 3 is slightly higher than the fork 2, it will not affect the insertion of the fork 2 into the plug plate. When the fork 2 is fully inserted into the bottom of the plug plate, the vehicle body 1 drives the fork 2 to move upward. At this time, the bottom of the plug plate squeezes the pressure block 3. When the pressure is greater than the thrust of the push assembly 4, the pressure block 3 moves downward. At this time, the connecting rod assembly 6 drives the block 5 to move above the top surface of the fork 2, thereby blocking the side of the plug plate away from the vehicle body 1, so as to prevent the vehicle body 1 from stopping suddenly during the forward movement, causing the cargo to slip off the fork 2 and cause losses.

[0029] In this embodiment, a groove 22 is provided on the top surface of the fork 2, and the bottom of the pressing block 3 is accommodated in the groove 22. When the upper part of the pressing block 3 is pressed with goods, the top surface of the pressing block 3 is higher than or equal to the top surface of the fork 2. Preferably, the top surface of the pressing block 3 is equal to the top surface of the fork 2, that is, the height of the pressing block 3 is equal to the depth of the groove 22, so that when the fork 2 is lifting the goods, the bottom surface of the plug plate slides and rubs against the top surface of the pressing block 3 and the fork 2 respectively, thereby increasing the friction area and preventing the plug plate or goods from being lifted by the pressing block 3 alone. Preferably, a rubber pad 31 is fixed on the top surface of the pressing block 3 to increase the friction between the pressing block 3 and the plug plate or goods, and at the same time prevent the plug plate or goods from causing long-term wear on the pressing block 3. Furthermore, the upper surface of the rubber pad 31 is provided with anti-slip grooves 311 to further increase the friction and prevent the goods from sliding off the fork 2 and causing losses. Preferably, the rubber pad 31 is fixedly connected to the pressing block 3 by bolts 32 to facilitate replacement of the worn rubber pad 31 .

[0030] In this embodiment, the push assembly 4 includes a slider 41, a U-shaped fixing rod 42, a fixing ring 43 and a compression spring 44. The slider 41 is vertically fixed on the bottom surface of the pressure block 3, and the bottom end of the slider 41 passes through the top surface of the fork 2 and extends to the inside of the through groove 21. The bottom end of the slider 41 is provided with a first clearance opening 411 along the length direction of the fork 2. The U-shaped fixing rod 42 is fixed in the through groove 21, and the top open end of the U-shaped fixing rod 42 is fixedly connected to the top wall of the through groove 21. The lower part of the U-shaped fixing rod 42 is penetrated in the first clearance opening 411. The fixing ring 43 is located inside the through groove 21 and is fixedly sleeved on the outer side wall of the slider 41, that is, the outer side wall of the slider 41 extending into the through groove 21 is fixedly sleeved with a fixing ring 43, and the outer side wall of the slider 41 is sleeved with a compression spring 44, and the two ends of the compression spring 44 are respectively abutted against the U-shaped fixing rod 42 and the fixing ring 43.

[0031] During implementation, the fixing ring 43 is pushed to the top surface of the through slot 21 by the pressure of the spring. At this time, the pressure block 3 is located above the top surface of the fork 2. When goods are pressed on the pressure block 3 and the pressure of the goods is greater than the elastic force of the spring, the pressure block 3 drives the slider 41 to move below the through slot 21. Then, the connecting rod assembly 6 connected to the pushing assembly 4 is driven to rotate, so that the connecting rod assembly 6 drives the stopper 5 to move above the top surface of the fork 2. Preferably, there are multiple sliders 41, and the multiple sliders 41 are evenly arranged along the length direction of the fork 2. The connecting rod assembly 6 is connected to any one of the sliders 41, so that the upward and downward movement of the pressure block 3 is more stable.

[0032] In this embodiment, the connecting rod assembly 6 includes a first rotating rod 61, a second rotating rod 62 and a connecting rod 64. The middle parts of the first rotating rod 61 and the second rotating rod 62 are rotatably connected to the side walls in the width direction of the through groove 21. The first rotating rod 61 is located on one side of the slider 41 and is inclined from bottom to top in the direction away from the vehicle body 1. The second rotating rod 62 is located on one side of the stopper 5, and the inclination direction is opposite to the inclination direction of the first rotating rod 61. The bottom ends of the slider 41 and the stopper 5 are respectively provided with a receiving groove 51, and the length direction of the receiving groove 51 is parallel to the length direction of the fork 2. The top end of the first rotating rod 61 and the bottom end of the second rotating rod 62 are respectively fixed with a cross rod 63, and the free end of each cross rod 63 is correspondingly slidably connected in the receiving groove 51 of the slider 41 and the stopper 5. The two ends of the connecting rod 64 are rotatably connected to the bottom end of the first rotating rod 61 and the top end of the second rotating rod 62 respectively.

[0033] During implementation, the cargo on the fork 2 presses the pressing block 3, and the pressing block 3 drives the slider 41 to move into the through slot 21. The slider 41 drives the cross bar 63 slidably connected to the receiving slot 51 of the slider 41 to move downward, thereby rotating the first rotating rod 61, and then driving the second rotating rod 62 to rotate through the connecting rod 64. At this time, the cross bar 63 on the second rotating rod 62 moves upward, thereby driving the stopper 5 to move toward the outside of the top surface of the fork 2, thereby blocking the cargo on the top surface of the fork 2 from moving away from the vehicle body 1, and preventing the cargo from sliding off the fork 2 and causing losses. Preferably, there are two connecting rod assemblies, and the two connecting rod assemblies 6 are respectively located on both sides of the through slot 21 in the width direction, so that the connection between the stopper 5 and the slider 41 is more stable.

[0034] When the utility model is implemented, the vehicle body 1 drives the fork 2 to move under the cargo. When the cargo is pressed onto the pressing block 3 and the pressure is greater than the thrust of the pushing assembly 4, the pressing block 3 drives the slider 41 to move under the through slot 21, thereby driving the connecting rod assembly 6 to rotate. Through the cooperation of the first rotating rod 61 and the second rotating rod 62, the cross bar 63 and the connecting rod 64, the stopper 5 moves to the outside of the top surface of the fork 2, thereby blocking the cargo on the top surface of the fork 2 from moving away from the vehicle body 1, and preventing the cargo from sliding off the fork 2. The rubber pad 31 and the anti-skid pattern 311 are provided to further increase the friction between the cargo and the pressing block 3, and prevent the cargo from sliding off the fork 2 and causing losses.

[0035] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of 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.
