This avoids the threaded slider from slipping due to the inertia of the large cargo, and improves the service life of the threaded slider.

Description

Technical Field

[0001] This utility model belongs to the field of cargo securing technology, specifically a securing device for large cargo in logistics. Background Technology

[0002] Logistics refers to the physical flow of goods from the supply location to the receiving location, encompassing basic functions such as transportation, storage, loading and unloading, handling, packaging, distribution processing, delivery, and information processing.

[0003] A search revealed an existing patent, CN218750525U, which describes a structure for securing large cargo in logistics. The patent addresses the common practice of placing large cargo on rough wooden pallets and securing it with ropes and hooks welded to the sides of the vehicle's cargo box. However, during transport, when the vehicle brakes, the cargo is prone to slipping relative to the vehicle due to inertia, posing a significant safety hazard. This patent addresses this by incorporating a clamping mechanism to hold large cargo of varying sizes, preventing slippage and improving transport safety. However, this patent has the following drawbacks in practical application:

[0004] This patent relies solely on the self-locking structure formed by the friction between the threaded slider and the screw thread to limit the movement of large items. When the logistics vehicle brakes suddenly, the inertia of the large items will squeeze the threaded slider. Over time, the threads of the threaded slider will strip, making it impossible to effectively limit the movement of large items. If the threaded slider strips during transportation, there is a serious safety hazard, so it needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to address the above problems. This utility model provides a device for securing large cargo in logistics, which has the advantage of preventing the threaded slider from slipping.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for large cargo in logistics, comprising a fixing device body, a circular hole inside the fixing device body, a lead screw movably sleeved inside the fixing device body, a threaded slider threadedly sleeved on the outer surface of the lead screw, the outer surface of the threaded slider movably connected to the inner surface of the fixing device body, a fixing block fixedly connected to the outer side of the threaded slider, a threaded rod threadedly connected to the inner surface of the fixing block, a lifting plate movably sleeved at the bottom of the threaded rod, the back of the lifting plate movably connected to the outer side of the threaded slider, connecting rods hinged to the left and right sides of the bottom of the lifting plate, a connecting block hinged to the other end of the connecting rod, the back of the connecting block movably connected to the outer side of the threaded slider, a pin fixedly connected to the outer side of the connecting block, the outer side of the pin penetrating the fixing device body and extending into the interior of the fixing device body.

[0007] As a preferred embodiment of this utility model, the pin is circular in shape, and the diameter of the pin is the same as the diameter of the circular hole.

[0008] As a preferred technical solution of this utility model, a groove is provided on the outer side of the threaded slider, a limiting block is movably connected to the inner surface of the groove, and the other end of the limiting block is fixedly connected to the back of the connecting block.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a fixing device for large cargo in logistics, including a fixing device body 1. A circular hole 2 is provided inside the fixing device body 1. A lead screw 3 is movably sleeved inside the fixing device body 1. A threaded slider 4 is threadedly sleeved on the outer surface of the lead screw 3. The outer surface of the threaded slider 4 is movably connected to the inner surface of the fixing device body 1. A fixing block 5 is fixedly connected to the outer side of the threaded slider 4. A threaded rod 6 is threadedly connected to the inner surface of the fixing block 5. A lifting plate 7 is movably sleeved at the bottom of the threaded rod 6. The back of the lifting plate 7 is movably connected to the outer side of the threaded slider 4. Connecting rods 8 are hinged to the left and right sides of the bottom of the lifting plate 7. The other end of the connecting rod 8 is hinged to a connecting rod. Block 9, the back of connecting block 9 is movably connected to the outside of threaded slider 4, and pin 10 is fixedly connected to the outside of connecting block 9. The outside of pin 10 passes through the body 1 of the fixing device and extends into the interior of the body 1 of the fixing device. When the rotating threaded rod 6 moves downward, it will drive the lifting plate 7 to move downward together. This action will cause the two connecting rods 8 to rotate, thereby driving the two connecting blocks 9 to move in opposite directions. As the connecting block 9 moves, the two pins 10 will also move in opposite directions and finally insert into the round hole 2. Through this series of actions, the threaded slider 4 is limited and locked, avoiding the threaded slider 4 from stripping due to the inertia of large goods.

[0023] The pin 10 is circular in shape, and its diameter is the same as that of the circular hole 2. This design allows the pin 10 to be properly inserted into the circular hole 2 to limit and lock the threaded slider 4.

[0024] The outer side of the threaded slider 4 is provided with a groove 11, and the inner surface of the groove 11 is movably connected to a limiting block 12. The other end of the limiting block 12 is fixedly connected to the back of the connecting block 9. The design of the groove 11 and the limiting block 12 serves to limit the connecting block 9 and ensure the stability of the horizontal movement of the connecting block 9.

[0025] The top of the fixing device body 1 is fixedly connected to the mounting frame 13, and the outer surface of the mounting frame 13 is movably connected to the wooden board 14. The bottom of the wooden board 14 is movably connected to the top of the fixing device body 1. The design of the mounting frame 13 serves to limit the wooden board 14. The top of the wooden board 14 is rough, which increases the friction with large goods, making it more stable to place large goods.

[0026] The lead screw 3 has a first bevel gear 15 fixedly sleeved on its outer surface. The outer surface of the first bevel gear 15 is movably connected to the inner surface of the fixing device body 1. The outer surface of the first bevel gear 15 is meshed with a second bevel gear 16. The inner surface of the second bevel gear 16 is fixedly sleeved with a movable rod 17. The top of the movable rod 17 passes through the fixing device body 1 and the wooden board 14 in sequence and extends to the top of the wooden board 14 and is fixedly sleeved with a turntable 18. Rotating the turntable 18 will drive the second bevel gear 16 to rotate around the movable rod 17 as the axis, thereby causing the second bevel gear 16 to mesh with the first bevel gear 15 and drive the lead screw 3 to rotate, thereby driving the threaded slider 4 to reciprocate left and right.

[0027] The threaded slider 4 is fixedly connected to a U-shaped block 19, and the inner surface of the U-shaped block 19 is movably connected to a shock-absorbing pad 20. The outer side of the shock-absorbing pad 20 is movably connected to the inner side of the threaded slider 4. The design of the U-shaped block 19 can limit the position of the shock-absorbing pad 20. The shock-absorbing pad 20 is detachable, and the gap between the pin 10 and the round hole 2 can be eliminated by disassembling and replacing the shock-absorbing pad 20 with different thicknesses, thereby ensuring that the pin 10 can be properly inserted into the round hole 2.

[0028] The number of threaded sliders 4 is four, and the four threaded sliders 4 are the same size. The four threaded sliders 4 are symmetrical about the center of the fixing device body 1. The design of four threaded sliders 4 has a better limiting effect on large goods and ensures the stability of large goods during transportation.

[0029] Working principle and usage process of this utility model:

[0030] When securing large items, first place the large items on top of the wooden board 14 and between the four threaded sliders 4. Then, rotate the four turntables 18, which will drive the four second bevel gears 16 to rotate around the four movable rods 17. This will cause the four second bevel gears 16 to mesh with the four first bevel gears 15, causing the four lead screws 3 to rotate. This will cause the four threaded sliders 4 to move left and right to hold the large items. At this time, the round hole 2 and the pin 10 correspond to each other, and the four threaded rods 6 rotate downwards, which will drive the four lifting plates 7 to move downwards. This will cause the eight connecting rods 8 to rotate, causing the eight connecting blocks 9 to move in opposite directions in pairs. This will cause the eight pins 10 to move in opposite directions in pairs and insert into the round hole 2, thus achieving the purpose of limiting and locking the four threaded sliders 4 and preventing the threaded sliders 4 from slipping due to the inertia of the large items.

[0031] When the round hole 2 and the pin 10 do not correspond, the gap between the pin 10 and the round hole 2 can be eliminated by replacing the shock-absorbing pad 20 with one of different thicknesses, thereby ensuring that the pin 10 can be properly inserted into the round hole 2.
