Description

Technical Field

[0001] This utility model relates to the field of logistics pallet technology, and in particular to a multifunctional logistics pallet. Background Technology

[0002] A logistics pallet is a horizontal platform device used for assembling, stacking, handling, and transporting goods. It is usually a flat rectangular or square structure and is mainly made of wood, plastic, metal, and composite materials. It plays a vital role in the logistics industry. When in use, it is loaded, unloaded, and handled by equipment such as forklifts and pallet trucks to achieve rapid transfer of goods.

[0003] Most existing logistics pallets consist of a fixed board structure and fixed legs. While they can meet basic handling needs, they have some drawbacks in actual use. When the pallet is being transported, the bumps from the forklift will cause the goods on the pallet to vibrate, which can easily lead to damage to the goods due to vibration or impact. Furthermore, when the pallet is removed from the forklift and needs to be moved a short distance, it can only be handled manually, which reduces the efficiency of logistics operations.

[0004] Therefore, in addressing the existing problems of existing logistics pallets where forklift jolting during transport causes vibration of goods on the pallet, easily leading to damage due to vibration or impact, and the need for manual handling when moving the pallet a short distance after it leaves the forklift, thus reducing logistics efficiency, this utility model uses a movable triangular structure composed of a movable extension plate, a load-bearing connecting plate, and a return spring. This structure can adaptively adjust according to the weight distribution of heavy objects when they are placed. Combined with a rubber pressure-bearing top block and a limiting slide groove, it disperses the pressure of heavy objects on the pallet, effectively improving the pallet's cushioning and shock resistance. Utility Model Content

[0005] To overcome the problems of existing logistics pallets, where the goods on the pallets are easily damaged by vibration or impact due to the bumps caused by forklifts during transportation, and where short-distance movement of the pallets after they leave the forklifts can only rely on manual handling, thus reducing the efficiency of logistics operations.

[0006] The technical solution of this utility model is as follows: a multifunctional logistics pallet, comprising a pallet body, a load-bearing connecting plate, and a concealed pulley assembly. A bottom support block is fixedly connected to the bottom end of the pallet body, and a concealed pulley assembly is provided inside the bottom support block. A load-bearing base plate is provided on the upper surface of the pallet body. Mounting cross plates are symmetrically fixedly connected to both sides of the pallet body. A rope-threading fixing ring is installed at the upper end of the mounting cross plate. A cavity is provided inside the pallet body. A movable extension plate is hinged to the inner wall of the cavity. A load-bearing connecting plate is hinged to the side end of the movable extension plate. The upper end of the load-bearing connecting plate is fixedly connected to the bottom end of the load-bearing base plate.

[0007] Preferably, a limiting groove is provided at the bottom of the internal cavity of the pallet body, and a rubber pressure-bearing top block is fixedly connected to the inner wall of the limiting groove. The lower end of the load-bearing connecting plate is slidably connected to the inside of the limiting groove, and the lower side of the load-bearing connecting plate is fixedly connected to the side of the rubber pressure-bearing top block.

[0008] Preferably, a reset spring is provided below the load-bearing connecting plate, one side of the reset spring is hinged to the bottom end face of the movable extension plate, and the other side of the reset spring is hinged to the bottom end face of the load-bearing connecting plate. An airbag lifting block is installed on the bottom inner wall of the cavity inside the pallet body, and the upper end of the airbag lifting block is fixed to the bottom end of the load-bearing base plate.

[0009] Preferably, a drainage channel is provided at the bottom of the internal cavity of the tray body, and elastic arc-shaped baffles are symmetrically hinged to both sides of the inner wall of the drainage channel.

[0010] Preferably, the concealed pulley assembly includes a mounting block, a caster wheel, a first extension protrusion, a second extension protrusion, a manual screw, a storage groove, and a magnetic block. The mounting block is rotatably connected to the interior of the bottom support block, and a caster wheel is provided at the lower end of the mounting block.

[0011] Preferably, a first extending protrusion is fixedly connected to the side end of the mounting connecting block, and a second extending protrusion is fixedly connected to the outer side of the bottom support block.

[0012] Preferably, the second extension protrusion is internally threaded with a manual screw, which passes through the second extension protrusion and is threaded to the inside of the first extension protrusion. The bottom end of the tray body is provided with a storage groove, and a magnetic block is provided inside the storage groove. The magnetic block and the caster are magnetically connected.

[0013] The beneficial effects of this utility model are:

[0014] 1. Through the coordinated operation of the movable extension plate, load-bearing connecting plate, rubber pressure-bearing top block, and limiting slide, it can adaptively adjust according to the weight and distribution of the goods to achieve the effect of dispersing pressure. At the same time, the return spring can be stretched when the load-bearing connecting plate is under force and slides to one side, which can absorb and disperse energy, play a buffering and shock-absorbing role, reduce the impact force when the goods are placed or when they are bumped during handling, protect the safety of the goods, and also extend the service life of the pallet body.

[0015] 2. The drainage channel and elastic arc-shaped baffles can promptly drain water from inside the pallet body. Normally, the elastic arc-shaped baffles block the drainage channel to prevent debris or water from the ground from entering the pallet body. When water accumulates inside the pallet body, the two symmetrical elastic arc-shaped baffles will open under water pressure to drain the water and prevent water from damaging the goods.

[0016] 3. The casters can be quickly stored inside the bottom support block. When the tray needs to be moved, the casters can be turned out for easy handling. When placing the tray, the casters can be stored in the storage slot, allowing the bottom support block to directly contact the ground and improve stability. At the same time, the magnetic block can magnetically attract the casters to prevent them from accidentally popping out. The manual screw can be used to fix the casters when they are open, passing through the first and second extension protrusions to prevent them from retracting into the storage slot during the movement of the tray body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model provides an embodiment: a multifunctional logistics pallet, including a pallet body 1, a load-bearing connecting plate 302, and a hidden pulley assembly. A bottom support block 2 is fixedly connected to the bottom end of the pallet body 1, and a hidden pulley assembly is provided inside the bottom support block 2. A load-bearing base plate 3 is provided on the upper end surface of the pallet body 1. Mounting horizontal plates 4 are symmetrically fixed to both sides of the pallet body 1. A rope fixing ring 5 is installed at the upper end of the mounting horizontal plate 4. A cavity is provided inside the pallet body 1. A movable extension plate 301 is hinged to the inner wall of the cavity. The load-bearing connecting plate 302 is hinged to the side end of the movable extension plate 301. The upper end of the load-bearing connecting plate 302 is fixed to the bottom end of the load-bearing base plate 3. The rope fixing ring 5 on the mounting horizontal plate 4 facilitates the use of ropes to fix the goods on the pallet, effectively preventing the goods from shaking or falling during transportation.

[0026] A limiting groove 303 is provided at the bottom of the internal cavity of the pallet body 1. A rubber pressure-bearing top block 304 is fixedly connected to the inner wall of the limiting groove 303. The lower end of the load-bearing connecting plate 302 is slidably connected to the inside of the limiting groove 303. The lower side of the load-bearing connecting plate 302 is fixedly connected to the side of the rubber pressure-bearing top block 304. When the load-bearing connecting plate 302 is subjected to force, its lower end slides in the limiting groove 303, squeezing the rubber pressure-bearing top block 304 in the limiting groove 303, which plays a preliminary buffering role.

[0027] A reset spring 305 is provided below the load-bearing connecting plate 302. One side of the reset spring 305 is hinged to the bottom end face of the movable extension plate 301, and the other side of the reset spring 305 is hinged to the bottom end face of the load-bearing connecting plate 302. An airbag lifting block 306 is installed on the bottom inner wall of the cavity inside the pallet body 1. The upper end of the airbag lifting block 306 is fixed to the bottom end of the load-bearing base plate 3. When the load-bearing connecting plate 302 is squeezed, it will slide to the side and downward, thereby causing the movable extension plate 301 to rotate around the hinge point, which stretches the reset spring 305. During the stretching process, the reset spring 305 absorbs and disperses energy, playing a buffering role.

[0028] The bottom of the internal cavity of the tray body 1 is provided with a drainage channel 307. The inner walls of the drainage channel 307 are symmetrically hinged with elastic arc-shaped baffles 308. When the accumulated water is discharged through the drainage channel 307, the water pressure pushes open the elastic arc-shaped baffles 308 or flows out from the gap.

[0029] The concealed pulley assembly includes a mounting block 201, a caster wheel 202, a first extension protrusion 203, a second extension protrusion 204, a manual screw 205, a storage slot 206, and a magnetic block 207. The mounting block 201 is rotatably connected to the inside of the bottom support block 2. The caster wheel 202 is provided at the lower end of the mounting block 201 and can be quickly stored inside the bottom support block 2.

[0030] The side end of the mounting connecting block 201 is fixed with a first extension protrusion 203, and the outer side of the bottom support block 2 is fixed with a second extension protrusion 204. The first extension protrusion 203 and the second extension protrusion 204 can be fixed by a manual screw 205 when the caster wheel 202 is opened.

[0031] The second extension protrusion 204 has a manual screw 205 internally threaded. The manual screw 205 passes through the second extension protrusion 204 and is threaded to the inside of the first extension protrusion 203. The bottom end of the tray body 1 has a storage groove 206. The storage groove 206 has a magnetic block 207 inside. The magnetic block 207 and the universal wheel 202 are magnetically connected. The magnetic block 207 magnetically attracts the universal wheel 202, which can prevent accidental pop-out.

[0032] Working principle: According to Figures 1-5 First, the load-bearing base plate 3 contacts the goods placed on the pallet body 1. After the load-bearing connecting plate 302 is subjected to force, its lower end slides in the limiting slide groove 303, squeezing the rubber pressure block 304 in the limiting slide groove 303, which plays a preliminary buffering role. At the same time, the load-bearing connecting plate 302 will slide to the side and downward under the pressure, so that the movable extension plate 301 rotates around the hinge point, causing the return spring 305 to be stretched. The return spring 305 absorbs and disperses energy during the stretching process, playing a buffering role. After the goods are unloaded, the return spring 305 contracts and drives the movable extension plate 301 and the load-bearing connecting plate 302 to return to their original positions. The airbag lifting block 306 can play a buffering and lifting role on the center position of the load-bearing base plate 3. The elastic arc baffle 308 normally blocks the drainage channel 307 to prevent debris or water from the ground from entering the interior of the pallet body 1. When water accumulates inside the pallet body 1, the two symmetrical elastic arc baffles 308 will open under the water pressure to drain the water and prevent water from damaging the goods.

[0033] according to Figure 6 Finally, the casters 202 can be quickly stored inside the bottom support block 2. When the pallet needs to be moved, the casters 202 can be turned out for easy handling. When placing the pallet, the casters 202 can be stored in the storage slot 206, so that the bottom support block 2 can directly contact the ground, improving stability. At the same time, the magnetic block 207 can magnetically attract the casters 202 to prevent them from popping out accidentally. When the casters 202 are opened, the manual screw 205 can fix them by threading through the first extension protrusion 203 and the second extension protrusion 204, preventing the casters 202 from retracting into the storage slot 206 during the movement of the pallet body 1.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
