Description

Technical Field

[0001] This utility model belongs to the field of unloading tools technology, specifically a truck unloading slide for logistics transportation. Background Technology

[0002] A loading slide is a device that uses gravity or mechanical power to slide goods from a high place (such as a truck, warehouse rack, second floor or above) to a lower place. Depending on its structure and function, loading slides can be divided into many types, such as simple loading slides, rolling loading slides, and automatic loading and unloading slides. They are widely used in logistics, warehousing, transportation, industrial production and other fields.

[0003] A search revealed a novel anti-impact loading and unloading slide with publication number CN218538560U. This slide addresses the problem of poor speed stability in conventional unloading slides. By incorporating an automatic resistance body and rotating rollers, the lever length formed by gravity increases with the tilt angle when the automatic resistance body tilts. This increases the force exerted by the automatic resistance body on the rotating rollers, thereby increasing the rotational resistance of the rollers as the tilt angle increases, thus slowing down the descent of goods. Conversely, tilting the slide increases the descent speed, providing the advantage of automatically balancing the descent speed. However, in actual use, due to the lack of a corresponding guiding mechanism for the ladder frame and rotating rollers, if the goods tilt during sliding, they are prone to falling from both sides of the ladder frame, causing them to crash directly onto the ground and resulting in damage. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a truck unloading slide for logistics transportation, which has the advantage of guiding goods.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a truck unloading slide for logistics transportation, comprising a ladder frame, with two support legs fixedly installed on the upper and lower sides of the left end of the ladder frame, and a buffer seat fixedly installed at the front end of each of the two support legs. A connecting plate is fixedly installed on the opposite face of each of the two support legs. Guide plates are movably connected to the upper and lower sides of the right end of the buffer seat, and two round rods are fixedly installed on the left end of the guide plates. The outer surfaces of the two round rods are movably sleeved with the inner surface of the buffer seat. Two rotating rods are movably connected to each other. Gears are fixedly installed at the bottom right end of each of the two rotating rods. The right ends of the two gears are movably connected to the left end of a connecting plate. Round shafts are movably connected inside each of the two rotating rods and gears. The right end of each round shaft is fixedly connected to the left end of the connecting plate. A first baffle is fixedly fitted onto the left side of the outer surface of each round shaft. The outer surface of the first baffle is movably connected to the outer surface of the rotating rod. Second baffles are fixedly fitted onto the left side of the outer surfaces of each of the two round rods. The outer surface of the second baffle is movably connected to the outer surface of the rotating rod.

[0006] As a preferred embodiment of this utility model, a limiting rod is fixedly sleeved on the left end inside the ladder frame, and limiting blocks are movably sleeved on the upper and lower sides of the outer surface of the limiting rod, and the outer surface of the limiting blocks is fixedly connected to the outer surface of the guide plate.

[0007] As a preferred embodiment of this invention, the ladder frame is movably fitted with a rotating roller, and an automatic resistance body is fixedly installed on the outer surface of the ladder frame.

[0008] As a preferred embodiment of this utility model, clamping rods are movably connected to the upper and lower sides of the middle left side of the connecting plate, and there are two clamping rods. A connecting rod is fixedly installed on the right side of each of the two clamping rods. The outer surface of the connecting rod is movably sleeved with the inner surface of the connecting plate. A short rod is fixedly installed on the right side of the connecting rod, and the left side of the short rod is movably connected to the right side of the connecting plate.

[0009] As a preferred embodiment of this invention, the right end of the short rod is hinged to a long rod, and the other end of the long rod is hinged to a rectangular block.

[0010] As a preferred embodiment of this utility model, a threaded rod is threadedly sleeved at the middle of the rectangular block, the left end of the threaded rod passes through the connecting plate and extends to the outside of the connecting plate and is fixedly sleeved with a handle, and the right end of the handle is movably connected to the left end of the connecting plate.

[0011] In a preferred embodiment of this utility model, cylinders are movably sleeved at the upper and lower ends of the rectangular block, the left end of the cylinders is fixedly connected to the right end of the connecting plate, a stop bar is fixedly sleeved on the right side of the outer surface of the cylinders, and the inner surface of the middle end of the stop bar is movably sleeved to the outer surface of the threaded rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes a guide plate, a round rod, a rotating rod, gears, and a round shaft. When the rotating rod is turned, the two gears mesh with each other, causing the two rotating rods to rotate in opposite directions around the round shaft. This generates a thrust on the outer surface of the round rod from the inner surface of the rotating rod, pushing the round rod along the inner surface of the connecting plate and causing the guide plate to move in opposite directions. In this way, the guide plate guides the goods, preventing them from falling from the sides of the ladder and improving the stability of the goods during the sliding process.

[0022] 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.

[0023] like Figures 1 to 7 As shown, this utility model provides a truck unloading slide for logistics transportation, including a ladder frame 1. Support legs 2 are fixedly installed on the upper and lower sides of the left end of the ladder frame 1, with two support legs 2 in total. A buffer seat 3 is fixedly installed at the front end of each of the two support legs 2. A connecting plate 4 is fixedly installed on the opposite side of each of the two support legs 2. Guide plates 5 are movably connected to the upper and lower sides of the right end of the buffer seat 3. Two round rods 6 are fixedly installed on the left end of the guide plate 5, with their outer surfaces movably sleeved with the inner surface of the buffer seat 3. Two rotating rods 7 are movably sleeved on the outer surfaces of the two round rods 6, with two rotating rods 7 in total. Gears 8 are fixedly installed at the bottom of the right end of each of the two rotating rods 7, with their right ends movably connected to the left end of the connecting plate 4. Round shafts 9 are movably sleeved inside the two rotating rods 7 and the gears 8, with the right end of the round shafts 9 connected to the connecting plate 4. The left end of the connecting plate 4 is fixedly connected, and the left side of the outer surface of the round shaft 9 is fixedly sleeved with the first baffle 10. The outer surface of the first baffle 10 is movably connected with the outer surface of the rotating rod 7. The left side of the outer surface of the two round rods 6 is fixedly sleeved with the second baffle 11. The outer surface of the second baffle 11 is movably connected with the outer surface of the rotating rod 7. When the rotating rod 7 is turned, since the rotating rod 7 and the gear 8 are fixedly connected and the two gears 8 are meshed, the two rotating rods 7 will rotate in opposite directions around the round shaft 9 under the action of the gear 8. Since the rotating rod 7 and the round rod 6 are movably sleeved, as the rotating rod 7 rotates, the rotating rod 7 will generate a thrust on the round rod 6, pushing the two round rods 6 to move in opposite directions with the guide plate 5. In this way, the guide plate 5 can block the goods, thereby preventing the goods from falling from the side when using the unloading slide, and thus improving the stability of the goods sliding on the unloading slide.

[0024] The ladder frame 1 has a fixed left end sleeved with a limiting rod 12. The upper and lower sides of the outer surface of the limiting rod 12 are respectively movably sleeved with limiting blocks 13. The outer surface of the limiting blocks 13 is fixedly connected to the outer surface of the guide plate 5. The outer surface of the limiting rod 12 and the inner surface of the limiting blocks 13 are both smooth, which ensures that the limiting blocks 13 will not get stuck when moving along the outer surface of the limiting rod 12. At the same time, the mutual cooperation between the limiting rod 12 and the limiting blocks 13 will restrict the movement of the guide plate 5, thereby ensuring the stability of the movement of the guide plate 5.

[0025] The ladder frame 1 has a rotating roller 14 inside, and an automatic resistance body 15 is fixedly installed on the outer surface of the ladder frame 1. The presence of the rotating roller 14 will prevent the goods from getting stuck, while the presence of the automatic resistance body 15 will facilitate the automatic balancing of the downward speed of the goods.

[0026] Two clamping rods 16 are movably connected to the upper and lower sides of the middle left side of the connecting plate 4. The right ends of the two clamping rods 16 are fixedly installed with connecting rods 17. The outer surface of the connecting rods 17 is movably sleeved with the inner surface of the connecting plate 4. The right end of the connecting rods 17 is fixedly installed with a short rod 18. The left end of the short rod 18 is movably connected to the right end of the connecting plate 4. When the short rod 18 is pulled, it will move the connecting rod 17 along the inner surface of the connecting plate 4, thereby causing the two clamping rods 16 fixedly connected to the connecting rod 17 to move towards each other along the outer surface of the connecting plate 4. In this way, the clamping rods 16 clamp the gear 8 to prevent the gear 8 from rotating.

[0027] The short rod 18 is hinged to a long rod 19 at its right end, and a rectangular block 20 is hinged to the other end of the long rod 19. When the rectangular block 20 moves, since the left and right ends of the long rod 19 are hinged to the short rod 18 and the rectangular block 20 respectively, one end of the long rod 19 will move along with the rectangular block 20, thereby generating a pulling force on the short rod 18 at the other end of the long rod 19, which will pull the short rod 18 to move.

[0028] The rectangular block 20 has a threaded rod 21 threadedly connected to its middle end. The left end of the threaded rod 21 passes through the connecting plate 4 and extends to the outside of the connecting plate 4, and is fixedly fitted with a handle 22. The right end of the handle 22 is movably connected to the left end of the connecting plate 4. When the handle 22 is rotated, the threaded rod 21 will rotate along the inner surface of the connecting plate 4. Since the outer surface of the threaded rod 21 is threadedly connected to the inner surface of the rectangular block 20, the rectangular block 20 will move as the threaded rod 21 rotates.

[0029] The rectangular block 20 has cylinders 23 movably sleeved at its upper and lower ends. The left end of the cylinder 23 is fixedly connected to the right end of the connecting plate 4. A stop bar 24 is fixedly sleeved on the right side of the outer surface of the cylinder 23. The inner surface of the middle end of the stop bar 24 is movably sleeved with the outer surface of the threaded rod 21. The cooperation between the cylinder 23 and the stop bar 24 will restrict the movement of the rectangular block 20, thereby ensuring the stability of the movement of the rectangular block 20. At the same time, the presence of the stop bar 24 can also provide auxiliary support for the threaded rod 21.

[0030] Working principle and usage process of this utility model:

[0031] Before unloading, the operator first moves the rotating rod 7 according to the size of the goods. Since the rotating rod 7 and the gear 8 are fixedly connected and the two gears 8 are meshed, the two rotating rods 7 will rotate in opposite directions under the drive of the two gears 8. This causes the inner wall of the rotating rod 7 to generate a thrust on the round rod 6, pushing the two round rods 6 to move in opposite directions with the guide plate 5. In this way, the goods can be guided by the guide plate 5, thereby preventing the goods from falling from both sides of the ladder frame 1 and improving the stability of the goods during the sliding process.

[0032] After the guide plate 5 is adjusted, the operator turns the handle 22, causing the threaded rod 21 to rotate along the inner surface of the connecting plate 4 and the stop bar 24. This causes the rectangular block 20, which is threadedly connected to the threaded rod 21, to move along the outer surface of the cylinder 23 with one end of the long rod 19. This causes the other end of the long rod 19 to exert a pulling force on the short rod 18, pulling the short rod 18 through the connecting rod 17 and causing the clamping rod 16 to move. The two clamping rods 16 then clamp and fix the gear 8 to prevent the gear 8 from rotating accidentally and requiring the guide plate 5 to be readjusted.
