Description

Technical Field

[0001] The invention relates to the technical field of pallets, in particular to an anti-skid and wear-resistant plastic pallet. Background Art

[0002] Plastic pallets are widely used in many fields such as logistics, transportation and warehousing. However, traditional plastic pallets are designed for convenience and are small in size. On the one hand, when transported by a forklift, the bottom of the pallet and the forklift tines are not well compatible. Since the bottom of the pallet is usually designed to be flat, it is difficult to insert the forklift tines, and manual assistance is often required to adjust the position of the pallet, which consumes manpower and time and reduces work efficiency. On the other hand, the end face of the pallet carrying the goods has insufficient wear resistance. After long-term use, the top plate is severely worn, which not only affects the appearance of the pallet, but also weakens its load-bearing stability, resulting in uneven placement of the goods and even causing safety hazards. Furthermore, during transportation, the goods are easily displaced and slipped due to the lack of effective anti-slip measures on the pallet, causing damage to the goods and bringing economic losses to the company.

The term "more than two" includes two or more than two situations.

[0019] See also Figures 1 to 10 As shown, the embodiment of the present application provides an anti-skid and wear-resistant plastic pallet, including a pallet body 10, and also includes: at least two anti-skid support base plates 20, a wear-resistant top plate 30, an end surface anti-skid mechanism 40 and a tilting mechanism 50, at least two anti-skid support base plates 20, at least one end of each anti-skid support base plate 20 can be rotated away from the pallet body 10; the wear-resistant top plate 30 is replaceably arranged on the top end surface of the pallet body 10 through a bolt assembly structure; the end surface anti-skid mechanism 40 is arranged in a groove at the top edge of the pallet body 10, and the end surface anti-skid mechanism 40 can be moved out of the groove and contact the goods; the tilting mechanism 50 is arranged in the inner cavity of the four corners of the pallet, the tilting mechanism 50 has a horizontal kinetic energy receiving component, and the tilting mechanism 50 is also transmission-connected to the anti-skid support base plate 20, for driving one side of the anti-skid support base plate 20 to protrude from the bottom end of the pallet, so as to realize that a higher height forklift insertion gap is formed on this side of the pallet body 10.

[0020] The anti-skid and wear-resistant plastic pallet provided by the present application has an anti-skid support base plate 20, one end of which can rotate away from the pallet body 10. When a forklift is needed to transport the pallet, the kinetic energy receiving component of the tilting mechanism 50 receives the horizontal kinetic energy, transmits and connects the anti-skid support base plate 20, and drives one side thereof to protrude from the bottom end of the pallet, so that a higher forklift insertion gap is formed on this side of the pallet body 10, which is convenient for forklift operation; the wear-resistant top plate 30 can be replaceably arranged on the top end face of the pallet body 10. When the top plate is worn and affects its use, a new top plate can be conveniently replaced to ensure the wear resistance of the top bearing surface of the pallet and extend the overall service life of the pallet; the end face anti-skid mechanism 40 is placed in a groove on the top edge of the pallet body 10. When goods are placed on the pallet, the end face anti-skid mechanism 40 can be moved outside the groove to contact the goods, thereby increasing the friction between the goods and the pallet, preventing the goods from sliding due to shaking and displacement during handling and transportation, and ensuring safe and stable transportation of goods. Therefore, the present device can ensure that the plastic pallet is anti-skid, wear-resistant and easy to transport by forklift.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, in some examples, further, the four corners of the top of the tray body 10 are respectively provided with reset buttons 60 corresponding to the position of the tilt mechanism 50, and the reset buttons 60 are used to form a reset movement environment in which the anti-skid support base plate 20 is integrally fitted to the tray body 10; a horizontal top frame 11 is also provided at the top of the tray body 10, and a plurality of strip grooves are provided on the edges of the top frame 11, and a cross groove is opened in the middle of the top frame 11, and the strip grooves and the cross groove correspond to the end face anti-skid mechanism 40.

[0022] In this example, reset buttons 60 corresponding to the tilting mechanism 50 are set at the four corners of the top of the pallet body 10. When the forklift completes the handling and the pallet does not need to be tilted, pressing the reset button 60 can create a reset movement condition for the anti-skid support base plate 20 to fit the pallet body 10 as a whole, so that the anti-skid support base plate 20 returns to the initial position and the pallet is restored to a stable placement state. The horizontal top frame 11 at the top of the pallet body 10, the multiple strip grooves on the edge and the cross groove in the middle correspond to the end surface anti-skid mechanism 40. When the goods are placed on the pallet and need to be fixed, the end surface anti-skid mechanism 40 can move under the restriction of the cross groove. The strip groove can meet the anti-skid requirements of goods of different sizes on the edge of the pallet. The cross groove is for the goods placed in the middle of the pallet, ensuring that the goods can be effectively resisted from all directions, further enhancing the anti-skid fixing ability of the pallet for the goods and ensuring the safety of cargo transportation.

[0023] like Figures 2 to 5 As shown, in some examples, further, the end anti-slip mechanism 40 includes: a lifting component 41, four connecting plates 42, four transmission rods 43 and four edge reinforcement components 44, the lifting component 41 can be movably set in the middle position of the tray body 10; the four transmission rods 43 can be movably set in the cross-shaped groove; the two ends of the four connecting plates 42 can be rotatably connected between the lifting component 41 and the transmission rod 43, and the top ends of multiple connecting plates 42 are in an outwardly inclined state; the four edge reinforcement components 44 are connected to the outer end of each transmission rod 43, and the top end of the edge reinforcement component 44 can be flush with the top end surface of the top frame 11, or protrude from the top end surface of the top frame 11.

[0024] In this example, when the goods on the pallet need to be anti-slip and fixed, the jacking assembly 41 located in the middle of the pallet body 10 starts to move. The jacking assembly 41 serves as a power source to drive the four connecting plates 42 rotatably connected to the two ends thereof. Since the two ends of the connecting plates 42 are respectively connected to the jacking assembly 41 and the transmission rod 43 that can move in the cross-shaped groove, the action of the jacking assembly 41 causes the connecting plates 42 to rotate, driving the transmission rod 43 to move outward along the cross-shaped groove, and the four side reinforcement assemblies 44 connected to the outer ends of the transmission rod 43 extend outward accordingly, and their top ends can be flush with the top end surface of the top frame 11 (abutting against the bottom end surface of the goods) or even protrude from the end surface (forming a stop structure to limit the sliding of the goods), so that the goods can be effectively blocked from the middle of the pallet to the surrounding areas to prevent the goods from sliding; for the goods placed on the edge of the pallet, the side reinforcement assembly 44 cooperates with the strip groove, and can also use the state change of the top end of the side reinforcement assembly 44 driven by the transmission rod 43 to resist the goods.

[0025] like Figure 5 As shown, in some examples, further, the lifting assembly 41 includes: a lifting shaft 411, two elastic support plates 412 and a center seat 413, the lifting shaft 411 is horizontally arranged at the middle position of the bottom end of the tray body 10; the bottom of the middle part of the two elastic support plates 412 is attached to the bottom outer wall of the lifting shaft 411, and the two sides of the top of the elastic support plate 412 can be slidably connected to the bottom outer wall of the tray body 10; the center seat 413 can be lifted and lowered and is connected to the middle inner cavity of the tray body 10, and the middle part of the lifting shaft 411 is fixed and passes through the center seat 413.

[0026] In this example, when the forklift is inserted and lifted up, the fork teeth come into contact with the elastic support plate 412, and the lifting shaft 411 located in the middle of the bottom end of the pallet body 10 moves first. The two elastic support plates 412 act as buffers. A reinforcing guard plate 4121 is also provided at the bottom end of the elastic support plate 412 to enhance the structural strength of the elastic support plate 412 and avoid deformation due to force, thereby forming a comprehensive support effect on the anti-slip support base plate 20. At the same time, the bottom end of the middle part of the elastic support plate 412 fits under the outer wall of the bottom end of the lifting shaft 411. When the lifting shaft 411 moves under force, the elastic support plate 412 can absorb part of the impact force by virtue of its own elastic deformation characteristics. At the same time, the two edges at the top thereof are respectively slidably connected to the bottom outer wall of the bottom end of the pallet body 10 to ensure that its own position is relatively stable and avoid shaking and displacement. The center seat 413 can be lifted and movably clamped in the middle inner cavity of the pallet body 10, and the middle of the lifting shaft 411 is fixed and passes through the center seat 413, so that when the lifting shaft 411 moves, it can synchronously drive the center seat 413 to lift and lower in the middle inner cavity of the pallet body 10, and the center seat 413 then drives the components connected to it, such as driving the transmission rod 43 and the edge reinforcement component 44 through the connecting plate 42 to operate, and collaboratively realize anti-slip treatment of the goods from the center of the pallet to the surrounding areas, to ensure that the goods are stable and do not slip.

[0027] like Figure 6 As shown, in some examples, further, the transmission rod 43 includes: an outer rod 431, an inner rod 432 and a spring 433. The outer rod 431 can be movably clamped in the cross-shaped groove, and one end of the outer rod 431 facing the center of the tray is rotatably connected to the connecting plate 42; the inner end of the inner rod 432 can be movably inserted into the inner cavity of the outer rod 431, and the other end of the inner rod 432 can be rotatably connected to the edge reinforcement assembly 44; the spring 433 is arranged in the inner cavity of the outer rod 431 and abuts against the end of the inner rod 432.

[0028] In this example, when the lifting assembly 41 is in operation, the connecting plate 42 is driven to rotate, and the outer rod 431 rotatably connected to the connecting plate 42 moves in the cross-shaped groove. Since the outer end of the outer rod 431 is connected to the connecting plate 42, its movement direction and amplitude are controlled by the connecting plate 42 to achieve the conversion of the displacement direction. The inner end of the inner rod 432 is movably inserted into the inner cavity of the outer rod 431 and can be extended and retracted relative to the outer rod 431. When the outer rod 431 is pushed outward, because the spring 433 is set in the inner cavity of the outer rod 431 and abuts the end of the inner rod 432, the spring 433 is first compressed to store a certain amount of elastic potential energy, and then the spring 433 releases the elastic potential energy to assist the inner rod 432 to extend outward, ensuring that the edge reinforcement assembly 44 rotatably connected to the other end of the inner rod 432 can timely and effectively abut the bottom end face of the cargo. If there is no squeezing of the edge reinforcement assembly 44 by the cargo, the inner rod 432 can be fully extended, the spring 433 does not store elastic potential energy, and the overall edge reinforcement assembly 44 can protrude from the wear-resistant top plate 30. Therefore, this example enables the transmission rod 43 to both accurately transmit power and adapt to different cargo volumes and cargo arrangements, thereby enhancing the anti-slip performance of the pallet.

[0029] like Figure 5 As shown, in some examples, further, the edge reinforcement assembly includes: an inner rotating plate and an outer rotating plate, the inner rotating plate can be movably arranged in the strip groove, a first upper bend is arranged on the outer end of the inner rotating plate, the outer end cross-section of the first upper bend is semicircular, and can abut against the bottom wall or side wall of the cargo; the inner rotating plate is rotatably connected to the inner rod; the rotation axis position of the outer rotating plate is the outer end side of the outer rotating plate, a second upper bend is arranged on the inner end of the outer rotating plate, and the second upper bend can be rotatably connected to both sides of the first upper bend.

[0030] In this example, during the process of the forklift inserting the pallet, as the transmission rod 43 moves, the outer rotating plate 442 rotatably connected to the inner rod 432 begins to move, and the second upper curved portion 444 at its outer end can rotate on both sides of the first upper curved portion 443, so that the outer rotating plate 442 can flexibly adjust the angle to better adapt to changes in the shape and position of the goods. At the same time, the inner rotating plate 441 that can rotate in the strip groove is rotatably connected with the first upper curved portion 443 due to the second upper curved portion 444. When the inner rotating plate 441 is driven, it will rotate around the rotating connection axis of the second upper curved portion 444 and the first upper curved portion 443, so that the arc-shaped end surface of the first upper curved portion 443 on its inner side is close to the goods. The outer end cross-section of the first upper curved portion 443 is semicircular in design, which can smoothly abut against the bottom wall of the goods to prevent the bottom of the goods from sliding outward, and can also fit against the side wall of the goods to limit the lateral movement of the goods, effectively limiting the goods from different directions. The inner rotating plate 441 and the outer rotating plate 442 cooperate with each other and operate in coordination, which greatly enhances the anti-slip and fixing ability of the pallet for the goods placed on the edge, and ensures that the goods are stably placed on the pallet.

[0031] like Figure 5 As shown, in some examples, further, a plurality of protrusions 445 are provided on the outer wall of the first upper curved portion 443 having a semicircular cross-section, and the plurality of protrusions 445 are located at different height positions on the outer wall of the first upper curved portion 443 .

[0032] In this example, when the pallet carries goods and the edge reinforcement assembly 44 operates to fix the goods, the first upper bend 443 of the inner rotating plate 441 is close to the goods. Due to the different positions of the protrusions 445, it can adapt to goods of different heights and irregular shapes. For goods with smoother surfaces, these protrusions 445 can increase the friction when in contact with the goods, making them fit the goods more closely and further preventing the goods from sliding on the pallet. Regardless of whether the goods are slightly vibrated during transportation or caused by the displacement trend caused by the bumpy transportation path, the protrusions 445 can rely on their own high friction characteristics, combined with the semicircular structure of the first upper bend 443, to strengthen the anti-slip constraints on the goods from multiple contact points, ensuring that the goods are always firmly placed on the pallet.

[0033] like Figure 3 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, in some examples, further, the tilting mechanism 50 includes: four pressing plates 51, an elastic abutment sheet 52, a first transmission wheel 53, a second transmission wheel 54, a spiral drive rod 55 and a telescopic column 56, the four pressing plates 51 are rotatably arranged on the outer sides of the two ends of the outer wall of the forklift insertion side of the pallet body 10; the elastic abutment sheet 52 is fixedly installed on the outer wall of the pallet body 10 and abuts against the inner side of the pressing plate 51; the first transmission wheel 53 is fixedly connected to the end of the pressing plate 51 and is rotatably arranged in the inner cavity of the corner of the pallet body 10; the second transmission wheel 54 is rotatably arranged In the inner cavity of the tray body 10, it is meshed and connected with the first transmission wheel 53; the top of the spiral drive rod 55 is provided with a columnar end 551, and the columnar end 551 is rotatably arranged in the inner cavity of the second transmission wheel 54, and a one-way transmission part is arranged between the columnar end 551 and the second transmission wheel 54, and the bottom end of the spiral drive rod 55 extends toward the bottom end of the tray; the telescopic column 56 is telescopically arranged in the inner cavity of the tray body 10, and the telescopic column 56 is sleeved on the outer side of the lower half of the spiral drive rod 55, and the bottom end of the telescopic column 56 is movably connected to the anti-slip support base plate 20 through a hinge seat 57.

[0034] In this example, when the forklift is ready to move the pallet, the forklift approaches the forklift insertion side of the pallet body 10, first contacts and presses the two pressing plates 51 rotatably arranged on the outer sides of both ends, and the inner side of the pressing plate 51 is pressed by the fixedly installed elastic abutment sheet 52, so it rotates around the axis and the rotation process is relatively stable. The first transmission wheel 53 fixedly connected to the end of the pressing plate 51 rotates in the inner cavity of the corner of the pallet body 10, and the second transmission wheel 54 meshing with the first transmission wheel 53 also rotates synchronously in the inner cavity of the pallet body 10. Since the top columnar end 551 of the spiral drive rod 55 is rotatably arranged in the inner cavity of the second transmission wheel 54, and a one-way transmission part is provided between the two, the second transmission wheel 54 can drive the spiral drive rod 55 to rotate in one direction when the second transmission wheel 54 rotates. The bottom end of the spiral drive rod 55 extends toward the bottom end of the pallet, and the telescopic column 56 sleeved on the outer side of the lower half thereof can be telescopic. When the spiral drive rod 55 rotates, the telescopic column 56 is driven by the spiral structure to realize the telescopic action. The bottom end of the telescopic column 56 is movably connected to the anti-skid support base plate 20 through the hinge seat 57, thereby driving one end of the anti-skid support base plate 20 to rotate away from the pallet body 10, so that a gap is formed on this side of the pallet body 10 for easy insertion of a forklift. During the whole process, various components cooperate closely to ensure that the pallet can be smoothly transported by a forklift.

[0035] like Fig. 9 As shown, in some examples, further, the one-way transmission part includes: a plurality of snap-fit ​​protrusions 541, two telescopic limit blocks 542 and an elastic connecting rod 543, and the plurality of snap-fit ​​protrusions 541 are respectively arranged on the inner wall of the second transmission wheel 54 in a circular array; the two telescopic limit blocks 542 are arranged in the inner cavity of the columnar end 551, and can movably penetrate and extend to contact the snap-fit ​​protrusions 541; the two ends of the elastic connecting rod 543 are respectively fixedly connected to the two telescopic limit blocks 542, and the connecting ends of the elastic connecting rod 543 and the telescopic limit blocks 542 are inclined sections.

[0036] In this example, a plurality of snap-fit ​​protrusions 541 are distributed along a circumferential array on the inner wall of the second transmission wheel 54, providing a force point for power transmission. Two telescopic limit blocks 542 are placed in the inner cavity of the columnar end 551, and can be movably extended through and contacted with the snap-fit ​​protrusions 541, and are limiting components for realizing unidirectional transmission. The two ends of the elastic connecting rod 543 are connected to the two telescopic limit blocks 542, and the connection end of the elastic connecting rod 543 with the telescopic limit block 542 is an inclined section, so that the telescopic movement of the telescopic limit block 542 is more flexible.

[0037] Working process: after the fork teeth come into contact with the pressing plate 51, the second transmission wheel 54 rotates in a specific direction, and at the same time drives the second transmission wheel 54 to start positive rotation. During the positive rotation, the telescopic limit block 542 and the multiple clamping protrusions 541 are used for unidirectional rotation transmission, so that the second transmission wheel 54 can be clamped on the columnar end 551 of the spiral drive rod 55 during the current rotation, and drive the columnar end 551 and the entire spiral drive rod 55 to rotate, and then the spiral structure of the spiral drive rod 55 drives the lower telescopic column 56 to extend outward, forming a current shape in which the height of the pallet increases; then the forklift evacuates the pallet, and the elastic abutment sheet 52 exerts its elastic force to reset the elastic force, driving the pressing plate 51 to reset. In this process, since one side of the clamping protrusion 541 is provided with an inclined end face, the telescopic limit block 542 is used for the second transmission wheel 54. One side end face of the limit block 542 is also provided with an inclined end face, which is similar to the shape of the ratchet teeth and the pawl teeth of the ratchet mechanism. At this time, although the second transmission wheel 54 is forced to rotate in the opposite direction, due to the one-way transmission function of the clamping protrusion 541 and the telescopic limit block 542, the columnar end 551 will not be driven to rotate. Therefore, the spiral drive rod 55 will not shrink at this time. It should be noted that the pressing plate 51 can only rotate within a fixed range. Therefore, even if the telescopic column 56 is in a state of being stressed by the gravity of the cargo, it cannot shrink within the rotation range of the pressing plate 51. At this time, the adjustment process of the push plate height is completed. If the lifting height of the front side of the pallet is still insufficient during the adjustment process, the forklift can continue to be controlled to abut the pressing plate 51 to perform the single-side end lifting process of the pallet as described above.

[0038] In the present process, it should be noted that the telescopic column 56 is telescopically arranged in the inner cavity at the four corners of the tray body 10 through a constant slow damping slide rail structure. On the one hand, the damping slide rail structure can limit the telescopic column 56 to follow the spiral drive rod 55 to make rotational motion, thereby more helpful to convert the rotational motion into a linear telescopic motion of the telescopic column 56. On the second hand, through the setting of the damping slider, the time required for the telescopic motion of the telescopic column 56 can be slowed down. For example, after the fork tine detaches from the pressing plate 51, the telescopic column 56 will not shrink rapidly, but the elastic abutment sheet 52 will preferentially push the pressing plate 51 to reset instantly, and lock the extension amount of the spiral drive rod 55, waiting for the next contact with the insert teeth.

[0039] like Fig.10 As shown, in some examples, further, the bottom end of the reset button 60 is provided with two guide frames 61 with grooves in the middle, and the guide frames 61 are mounted on the inclined section of the connecting rod to drive the two telescopic limit blocks 542 to retract.

[0040] In this example, when the tray is used or transferred, when it is necessary to restore the tray to its initial state, that is, to make the anti-skid support base plate 20 fit the tray body 10 as a whole, press the reset button 60. The two guide frames 61 with grooves in the middle provided at the bottom of the reset button 60 move downward. Since the guide frames 61 are mounted on the inclined section of the elastic connecting rod 543, the action of pressing the reset button 60 will cause the guide frames 61 to be pressed downward. With the cooperation of the grooves and the inclined section of the elastic connecting rod 543, pressure is accurately applied to the inclined section of the elastic connecting rod 543, thereby driving the two telescopic limit blocks 542 to contract. After the telescopic limit blocks 542 contract, they are out of contact with the clamping protrusions 541 on the inner wall of the second transmission wheel 54, so that the spiral drive rod 55 is no longer constrained by the unidirectional transmission of the second transmission wheel 54. At this time, the anti-skid support base plate 20 can return to the initial position of fitting with the tray body 10 under the action of its own gravity, so that the tray can be restored to stability and ensure the normal use of the tray in the future.

For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
