Abstract
Description
Technical Field
[0001] This utility model relates to the field of cargo securing technology, specifically to a cargo securing device for transportation. Background Technology
[0002] Cargo securing frames are specialized auxiliary structures used to stabilize cargo positions in road, rail, sea, and air freight scenarios. They effectively limit the displacement, shaking, and collisions of cargo caused by bumps, turns, acceleration, or deceleration during transportation. This not only prevents damage or deformation of cargo to ensure transportation quality but also prevents cargo displacement from causing scratches or damage to the transport carrier, reducing the risk of transportation accidents caused by improper cargo securing.
[0003] However, many existing cargo securing racks can only secure items of a single size and cannot effectively secure goods of different lengths and widths, resulting in poor applicability. In fact, many securing racks have very poor securing effects, causing shaking and displacement between the securing rack and the goods, which in turn causes wear and tear on the surface of the goods.
[0004] This utility model can effectively fix and clamp goods of different lengths and widths, improve the applicability of the fixing frame, and also has the ability to be disassembled for transportation, which has certain practicality. Utility Model Content
[0005] The purpose of this utility model is to provide a cargo transport fixing frame to solve the above problems. It can effectively fix and clamp cargo of different lengths and widths, improve the applicability of the fixing frame, and also has the ability to be disassembled for transport, which has certain practicality.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: a cargo transport fixing frame, comprising a transport base plate and a fixing frame, wherein two fixing frames are provided and symmetrically distributed, and a transverse lead rod is fixedly installed between the inner walls of both ends of the fixing frame. Each transverse lead rod has three sliding blocks on its body, and the sliding blocks are slidably connected to the inner walls of both sides of the fixing frame. Each sliding block has a through hole in its middle for the transverse lead rod to pass through, and each sliding block has a positioning nut on both sides that is threadedly connected to the transverse lead rod. A second support plate is fixedly connected to the inner side of the sliding blocks distributed at both ends of the transverse lead rod, and a first support plate is fixedly connected to the inner side of the sliding blocks distributed in the middle section of the transverse lead rod. An L-shaped limiting plate is fixedly connected to the top side of the second support plate, and a T-shaped limiting plate is fixedly connected to the top side of the first support plate. Rubber pads are adhered to the inner walls of both the T-shaped and L-shaped limiting plates.
[0007] Preferably, the bottom side of the transverse lead screw is symmetrically fixedly connected with two pins, and the outer side of the transverse lead screw is symmetrically fixedly connected with two upper threaded seats.
[0008] Preferably, the fixing frame is threadedly connected to a lower threaded seat via an upper threaded seat and a bolt and nut assembly. The lower threaded seat is fixedly connected to a sliding plate, and the top side of the sliding plate has two symmetrical insertion holes adapted to the pins.
[0009] Preferably, four T-shaped slide rails are symmetrically slidably connected to the two lower threaded seats, and a transport base plate is fixedly connected to the bottom side of the four T-shaped slide rails.
[0010] Preferably, a sliding groove is provided through the middle of the transport base plate, and a bidirectional lead screw is rotatably installed between the inner walls of the two ends of the sliding groove via bearings.
[0011] Preferably, the bidirectional lead screw is driven by a motor fixedly installed on the outer wall of the transport base plate, and two threaded sleeves are symmetrically installed on the two threaded portions of the bidirectional lead screw with opposite directions of rotation. The threaded sleeves are slidably connected to the inner wall of the sliding groove.
[0012] Preferably, a connecting block is fixedly connected to the top side of each threaded sleeve, and the top end of the connecting block is fixedly connected to the middle of the bottom side of the corresponding sliding plate.
[0013] Compared with the prior art, the present invention provides a cargo transport fixing frame, which has the following advantages: This invention features symmetrically distributed fixed frames and internally mounted transverse lead screws via bearings. The spacing of three sliding blocks on each fixed frame can be adjusted to accommodate goods of varying lengths. The sliding blocks pass through through holes in the transverse lead screw and are locked in place by positioning nuts on both sides, ensuring stability after adjustment. The inner sides of the sliding blocks at both ends of the transverse lead screw are connected to second support plates, while the inner side of the middle sliding block is connected to a first support plate, together supporting the bottom of the goods and improving stability. An L-shaped limiting plate on the top side of the second support plate cooperates with a T-shaped limiting plate on the top side of the first support plate to control the movement of goods. The side of the goods is limited, and the rubber pads bonded to the inside effectively prevent wear on the surface of the goods. In addition, the fixing frame is connected to the upper and lower threaded seats through the upper threaded seat and the pins cooperate with the holes on the sliding plate to achieve quick installation and disassembly. The bottom side of the sliding plate is slidably connected to the transport base plate through the T-shaped slide rail, and the motor drives the double-acting screw to move the threaded sleeve, which in turn pushes the sliding plate along the T-shaped slide rail through the connecting block, so as to adjust the distance between the two fixing frames to accommodate goods of different widths. The overall structure has strong linkage and is easy to operate, which greatly improves the applicability and fixing effect of the fixing frame. Attached Figure Description

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. Example
[0016] like Figure 1 , Figure 3 and Figure 4As shown, this utility model provides a cargo transport fixing frame, including a transport base plate 1 and a fixing frame 11. Two fixing frames 11 are provided and symmetrically distributed. A transverse lead screw 12 is fixedly installed between the inner walls of both ends of the fixing frame 11. Three sliding blocks 13 are provided on the body of each transverse lead screw 12. The sliding blocks 13 are slidably connected to the inner walls of both sides of the fixing frame 11. Each sliding block 13 has a through hole 21 in its center for the transverse lead screw 12 to pass through. The sliding blocks 13 have through holes 21 on both sides... Each component is equipped with a positioning nut 14 threadedly connected to the transverse lead screw 12. A second support plate 22 is fixedly connected to the inner side of the sliding blocks 13 distributed at both ends of the transverse lead screw 12. A first support plate 15 is fixedly connected to the inner side of the sliding blocks 13 distributed in the middle section of the transverse lead screw 12. An L-shaped limiting plate 17 is fixedly connected to the top side of the second support plate 22, and a T-shaped limiting plate 16 is fixedly connected to the top side of the first support plate 15. Rubber pads 18 are adhered to the inner walls of both the T-shaped limiting plate 16 and the L-shaped limiting plate 17. The fixing frame 11 provides the main support structure. The sliding blocks 13 are sleeved on the transverse lead screw 12 through through holes 21 and locked in position by the positioning nuts 14, thereby achieving precise adjustment and fixation of the position. The sliding blocks 13 located at different positions on the lead screw are respectively connected to the first support plate 15 or the second support plate 22, all used to support goods. The T-shaped limiting plate 16 and the L-shaped limiting plate 17 are used to restrict the movement of goods from the side, and the rubber pads 18 on their surfaces serve to cushion and protect the surface of the goods. Example
[0017] Please see Figure 3 The bottom side of the transverse lead screw 12 is symmetrically fixedly connected with two pins 19, and the outer side of the transverse lead screw 12 is symmetrically fixedly connected with two upper threaded seats 20. The pins 19 are used to cooperate with the insertion hole 9 to achieve quick positioning, and the upper threaded seats 20 are detachably fixedly connected to the lower threaded seats 10 through a threaded connection. Example
[0018] Please see Figure 2 The fixed frame 11 is threadedly connected to the lower threaded seat 10 via the upper threaded seat 20 and the bolt and nut assembly. The lower threaded seat 10 is fixedly connected to the sliding plate 7. The top side of the sliding plate 7 has two symmetrical insertion holes 9 that are adapted to the pin 19. Example
[0019] Please see Figure 1 and Figure 2 Four T-shaped slide rails 8 are symmetrically slidably connected to the two lower threaded seats 10, and the bottom sides of the four T-shaped slide rails 8 are fixedly connected to the transport base plate 1. The T-shaped slide rails 8 are used to guide the sliding plate 7 to move linearly, and the transport base plate 1 serves as the basic load-bearing structure of the entire device. Example
[0020] Please see Figure 1 and Figure 2 The transport base plate 1 has a through-type sliding groove 2 in the middle, and a bidirectional lead screw 3 is rotatably mounted between the inner walls of the two ends of the sliding groove 2 via bearings. The bidirectional lead screw 3 can drive two threaded sleeves 5 on it to move in opposite directions in a linear motion by rotation, and the sliding groove 2 provides constraint and guidance for the movement of the threaded sleeves 5. Example
[0021] Please see Figure 1 and Figure 2 The bidirectional lead screw 3 is driven by a motor 4 fixedly mounted on the outer wall of the transport base plate 1. Two threaded sleeves 5 are symmetrically mounted on the two threaded portions of the bidirectional lead screw 3 with opposite directions of rotation. The threaded sleeves 5 are slidably connected to the inner wall of the sliding groove 2. The motor 4 provides rotational power to the bidirectional lead screw 3, enabling it to rotate continuously. The threaded sleeves 5 convert the rotational motion of the bidirectional lead screw 3 into its own linear movement. Example
[0022] Please see Figure 1 and Figure 2 Each threaded sleeve 5 has a connecting block 6 fixedly connected to its top side. The top of the connecting block 6 is fixedly connected to the middle of the bottom side of the corresponding sliding plate 7. The connecting block 6 is used to transmit the linear motion of the threaded sleeve 5 to the sliding plate 7, thereby driving the sliding plate 7 and the entire fixed frame 11 structure on it to move, so as to realize the function of adjusting the distance between the two fixed frames 11 according to the width of the goods.
[0023] The working principle of the cargo transport fixing frame provided by this utility model is as follows: First, adjust the distance between the two fixed frames 11 according to the size of the goods to be transported. Start the motor 4 to drive the bidirectional lead screw 3 to rotate, causing the two threaded sleeves 5 to move in opposite directions along the sliding groove 2. The threaded sleeves 5 drive the sliding plate 7 to slide along the T-shaped slide rail 8 through the connecting block 6, thereby adjusting the width position of the fixed frame 11. Next, adjust the position of the sliding block 13 so that the sliding block 13 slides along the inner wall of the fixed frame 11, adjusting the distance between the first pallet 15 and the second pallet 22 to accommodate the length of the goods. After adjustment, tighten the positioning nuts 14 on both sides of the sliding block 13 to fix the sliding block 13 to the transverse lead screw 12. Then, place the goods on the first pallet 15 and the second pallet 22, and limit them from the side by the T-shaped limiting plate 16 and the L-shaped limiting plate 17, where the rubber pad 18 provides cushioning protection. Finally, the connection between the fixed frame 11 and the sliding plate 7 is further reinforced by the bolt connection between the upper threaded seat 20 and the lower threaded seat 10, and the insertion of the pin 19 into the insertion hole 9, to ensure that the goods are stable and without displacement during transportation.
