DETAILED DESCRIPTION

[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] The present invention provides the following preferred embodiments:

[0029] Example 1, as Figure 1-Figure 7 As shown, a fork with an anti-slip function includes a lower fork body 11, a middle fork body 12 and an upper fork body 13, which are arranged in sequence from bottom to top. The lower fork body 11, the middle fork body 12, the upper fork body 13 and the telescopic mechanism can form a fork body. The telescopic mechanism in the fork is a prior art and will not be elaborated here. It also includes a receiving groove 14, a support plate 15 and an anti-slip mechanism. The receiving groove 14 is opened in the middle of the top end of the upper fork body 13, and the support plate 15 is located above the receiving groove 14. The sizes of the receiving groove 14 and the support plate 15 match. Specifically, when the support plate 15 moves into the interior of the receiving groove 14, the plane where the top end surface of the support plate 15 is located is flush with the plane where the top end surface of the upper fork body 13 is located, and the anti-slip mechanism is provided on the upper fork body 13;

[0030] The anti-slip mechanism includes two limiting rollers 34, two mounting plates 39, two transmission assemblies, two rotating assemblies and four pressing assemblies. The two mounting plates 39 are symmetrically fixed to the two ends of one side of the upper fork body 13. The two limiting rollers 34 are symmetrically arranged at the two ends of the upper fork body 13. Each rotating assembly is located between a limiting roller 34 and a mounting plate 39. The rotating assembly is used to drive the limiting roller 34 to rotate. Each two pressing assemblies are symmetrically arranged on one side of a support plate 15. Each transmission assembly is located between a rotating assembly and one of the pressing assemblies.

[0031] When the cargo falls on the upper fork body 13, the cargo presses the support plate 15 to move downward. At this time, the support plate 15 drives the downward pressure component to work. Under the action of the transmission component, when the downward pressure component is in operation, it can drive the rotation component to operate, so that the two limiting rollers 34 at both ends can rotate, so that the two limiting rollers 34 can be used to limit both ends of the cargo. When the forklift stops suddenly, the limiting rollers 34 on both sides are used to block the cargo from sliding out under the action of inertia, which can prevent the cargo from sliding out, thereby reducing damage caused by the cargo sliding out and effectively improving the anti-slip performance of the fork.

[0032] like Figure 1-Figure 7 As shown, each pressing assembly includes an avoidance groove 17, a lower pressing plate 18, a lower pressing rod 19, a limit block 20 and a first spring 21. The avoidance groove 17 is opened on the upper fork body 13, and the avoidance groove 17 is communicated with the accommodating groove 14. The lower pressing plate 18 is located above the avoidance groove 17 and cooperates with the avoidance groove 17. One end of the lower pressing plate 18 is installed on one side of the support plate 15. When the support plate 15 moves into the interior of the accommodating groove 14, it can drive the lower pressing plate 18 to move into the interior of the avoidance groove 17. The limit block 20 is located below the lower pressing plate 18 and is fixedly installed on one side of the upper fork body 13. The lower pressing rod 19 is slidably set on the limit block 20. The top end of the lower pressing rod 19 is fixedly connected to the lower pressing plate 18. The first spring 21 is sleeved on the outer side of the lower pressing rod 19. The two ends of the first spring 21 are respectively connected to the limit block 20 and the lower pressing plate 18.

[0033] In the initial state, the support plate 15 is located above the upper fork body 13, and the first spring 21 is in a natural state. When the cargo falls on the upper fork body 13, the cargo presses the support plate 15 so that the support plate 15 moves into the interior of the accommodating groove 14, and the support plate 15 drives the lower pressure plate 18 to move into the interior of the avoidance groove 17. The lower pressure plate 18 drives the lower pressure rod 19 to move on the limit block 20. At this time, the first spring 21 is compressed;

[0034] When the goods leave the upper fork body 13 , that is, when unloading, the first spring 21 can drive the lower pressing plate 18 to return to its original position, so that the support plate 15 can leave the receiving groove 14 again.

[0035] like Figure 1-Figure 7 As shown, each rotating assembly includes a rotating shaft 32, a gear 31, a rotating rod 33, a rack 29 and a reset member. The rack 29 is slidably set on one side of the mounting plate 39. The rotating shaft 32 is rotatably set on the mounting plate 39 through a bearing. One end of the rotating rod 33 is fixedly mounted on the rotating shaft 32, and the other end of the rotating rod 33 is fixedly connected to one end of the limiting roller 34. The gear 31 is located on one side of the rotating rod 33 and fixed to the surface of the rotating shaft 32. The gear 31 and the rack 29 are meshed with each other. The reset member is installed between the rack 29 and the mounting plate 39.

[0036] When the support plate 15 moves downward, it drives the lower pressure rod 19 downward. At this time, under the action of the transmission assembly, it can drive the rack 29 to move away from the lower pressure rod 19. Since the rack 29 and the gear 31 are engaged with each other, the rack 29 can drive the gear 31 to rotate when moving, thereby driving the rotating rod 33 to rotate through the rotating shaft 32, so that the limiting roller 34 can rotate to the top of the upper fork body 13, thereby achieving the limitation of the goods and preventing the goods from slipping out.

[0037] like Figure 1-Figure 7 As shown, the reset member includes a side plate 35, a guide rod 36, a fixed plate 37 and a second spring 38. The side plate 35 is fixedly mounted on the bottom of one end of the rack 29. The fixed plate 37 is located at the end of the rack 29 away from the side plate 35. The fixed plate 37 is fixedly mounted on the mounting plate 39. The guide rod 36 is slidably set on the fixed plate 37. One end of the guide rod 36 is fixedly connected to the side plate 35. The second spring 38 is sleeved on the guide rod 36. The two ends of the second spring 38 are respectively connected to the fixed plate 37 and the side plate 35.

[0038] In the initial state, the second spring 38 is in a natural state. When the rack 29 moves away from the lower pressure rod 19, the rack 29 drives the side plate 35 to move, and the side plate 35 drives the guide rod 36 to slide on the fixed plate 37, and the second spring 38 is compressed.

[0039] like Figure 1-Figure 7 As shown, each transmission assembly includes a wedge block 22, a roller 25, an adapter frame 26 and a push rod 27. The wedge block 22 is fixedly mounted below one of the lower pressure rods 19. The wedge block 22 is slidably mounted on one side of the mounting plate 39. One end of the push rod 27 is fixedly connected to one end of the rack 29. The other end of the push rod 27 is connected to the adapter frame 26. The roller 25 is rotatably mounted on the adapter frame 26. The roller 25 and the wedge block 22 are in contact with each other.

[0040] When the lower pressure rod 19 moves downward, the lower pressure rod 19 drives the wedge block 22 to move downward. At this time, the wedge block 22 can drive the roller 25 to move, so that the push rod 27 can move in the direction close to the rack 29. That is, when the wedge block 22 moves downward, the push rod 27 can drive the rack 29 to move, the second spring 38 is compressed, and the limiting roller 34 can rotate to the top of the upper fork body 13 to limit the cargo.

[0041] When the cargo leaves the upper fork body 13 and the lower pressure rod 19 moves upward, the lower pressure rod 19 drives the wedge block 22 to move upward, and drives the rack 29 to reset under the action of the second spring 38. At this time, the limiting roller 34 can rotate in the opposite direction to one end of the upper fork body 13 to prepare for the next cargo transportation.

[0042] like Figure 1-Figure 7As shown, one side of the wedge block 22 is provided with a slide groove 23 fixedly mounted on the mounting plate 39, and a slider 24 is slidably connected inside the slide groove 23. The slider 24 is fixed to one side of the wedge block 22, and a first guide rail 28 and a second guide rail 30 are fixed to the surface of the mounting plate 39. The rack 29 is slidably set inside the second guide rail 30, and the push rod 27 is slidably set inside the first guide rail 28. The slide groove 23 and the slider 24 can be used to guide the wedge block 22, the first guide rail 28 can be used to guide the push rod 27, and the second guide rail 30 can be used to guide the rack 29, thereby ensuring the stability of the forklift during operation.

[0043] like Figure 1-Figure 7 As shown, the top surface of the support plate 15 is provided with multiple anti-slip teeth 16, and the multiple anti-slip teeth 16 are equidistantly arranged on the support plate 15. Arranging several anti-slip teeth 16 at the top of the support plate 15 can further improve the anti-slip effect of the surface of the support plate 15 and meet the usage requirements.

[0044] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
