[0026] 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.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Please see Figure 1-5 This utility model provides a technical solution:

[0029] An adaptive binding and fixing device for a truck compartment includes a C-shaped steel rail 1, with a fixing component 2 fixedly connected to the inner side of the C-shaped steel rail 1. The inner wall of the C-shaped steel rail 1 has toothed grooves 3 at both corners. The fixing component 2 includes a support rail 21, with a support groove 22 on one side. A slider nut body 23 is slidably connected to the inner side of the support groove 22. A limiting mechanism 24 is provided on one side inside the slider nut body 23. A connecting mechanism 25 is threadedly connected to the front end face of the slider nut body 23. A triangular lifting ring 26 is installed at the front end of the connecting mechanism 25. The triangular lifting ring 26 contains... Limiting grooves 27 are provided in both corner areas on the side; the limiting mechanism 24 includes a mounting cavity 241, which is located inside the slider nut body 23 on one side. A return spring 242 is fixedly connected to the inner wall of the mounting cavity 241 near the connecting mechanism 25. A connecting plate 243 is fixedly connected to the front end of the return spring 242. Tooth blocks 244 are fixedly connected to both ends of the connecting plate 243. A pressing block 245 is fixedly connected to the middle of the connecting plate 243. The front end of the pressing block 245 extends to the outside of the slider nut body 23. The tooth blocks 244 mesh with the tooth grooves 3.

[0030] As a further implementation of this solution, each mounting cavity 241 is provided with two return springs 242. The two return springs 242 are arranged symmetrically on the left and right with the compression block 245 as the center. The compression block 245 is slidably connected to the slider nut body 23. The two toothed blocks 244 are arranged symmetrically on the left and right with the compression block 245 as the center. One end of the mounting cavity 241 is a slope structure. The two toothed blocks 244 are slidably connected to the two sides of the front end face of the slider nut body 23 respectively. In this arrangement, the rubber block 254 applies pressure to the front end of the compression block 245, so that the compression block 245 drives the connecting plate 243 to move away from the adjusting plate 252. The connecting plate 243 then drives the toothed blocks 244 at both ends to retract inward, so that the front end of the toothed blocks 244 disengages from the corresponding toothed groove 3. The slope structure at one end of the mounting cavity 241 facilitates the fit with the inner wall of the mounting cavity 241, increasing the movement space of the toothed blocks 244.

[0031] As a further implementation of this solution, the connecting mechanism 25 includes a connecting rod 251, which is threaded to the middle of the front end face of the slider nut body 23. An adjusting plate 252 is rotatably connected to the middle of the connecting rod 251. An anti-sliding block 253 is fixedly connected to the front end face of the adjusting plate 252. A rubber block 254 is fixedly connected to the rear end face of the anti-sliding block 253. The rubber block 254 is located in front of the extrusion block 245. This arrangement facilitates the application of pressure to the extrusion block 245 by the universal rubber block 254.

[0032] As a further implementation of this scheme, the number of slider nut bodies 23 is set to a certain number, and the number of slider nut bodies 23 is arranged linearly. The number of tooth grooves 3 is set to two sets, and the tooth grooves 3 are parallel to each other with the C-shaped steel rail 1. The two sets of tooth grooves 3 are arranged symmetrically with the support rail 21 as the center. This symmetrical design avoids transmission failure or damage caused by skewness or asymmetry, and can effectively limit and fix the slider nut bodies 23.

[0033] As a further implementation of this solution, the number of triangular lifting rings 26 is the same as the number of slider nut bodies 23. A tightening band 4 is installed between several triangular lifting rings 26. The tightening band 4 is a polyester fiber band with a width of 50mm and has high tensile strength. A band retractor 5 is installed on one side of the tightening band 4. A fixing hook 6 is installed in the corner area of ​​the triangular lifting ring 26. The position of the fixing hook 6 corresponds to the position of the limiting groove 27. A nylon band 7 is fixedly connected to the rear end of the fixing hook 6. The setting of the fixing hook 6 makes it easy to fix the nylon band 7 to the upper surface of the goods, thereby improving the stability of the goods. The limiting groove 27 opened in the inner corner area of ​​the triangular lifting ring 26 restricts the range of motion of the fixing hook 6, making it less likely to slide and improving stability.

[0034] Workflow: The self-adaptive binding and fixing device for the freight car body is horizontally installed to one side of the car body using the mounting holes at both ends of the C-shaped steel rail 1 and the bolt and nut assembly. The C-shaped steel rail 1 has a cross-sectional dimension of 40mm*20mm, suitable for freight cars 4-10 meters long. The length of the C-shaped steel rail 1 can be customized according to the specific length of the car body. During use, the tightening strap 4 is placed on the outside of the goods; excess length can be wound up using the strap retractor 5. Since several sliding nut bodies 23 can slide through the fixing component 2, the operator first adjusts the position of the two sliding nut bodies 23 closest to the middle according to the length of the goods. The number of fixing points can be increased according to the quantity and size of the fixed items to accommodate goods of different specifications. In its natural state, the slider nut body 23 is fixed by the cooperation of the limiting mechanism 24 and the tooth groove 3. When the position of the slider nut body 23 is adjusted, the anti-sliding block 253 presses the adjusting plate 252, causing the adjusting plate 252 to move closer to the position of the pressing block 245. During the rotation of the adjusting plate 252, the rubber block 254 moves synchronously, and the rubber block 254 applies pressure to the front end of the pressing block 245, causing the pressing block 245 to drive the connecting plate 243 to move away from the adjusting plate 252. The connecting plate 243 then drives the tooth blocks at both ends. 244 retracts inward, causing the front end of the toothed block 244 to disengage from the corresponding toothed groove 3. At this time, the slider nut body 23 can move horizontally along the path of the fixing component 2, and the two middle slider nut bodies 23 are moved to both sides of the goods. While the slider nut bodies 23 move, the tightening band 4 slides along the inner side of the triangular lifting ring 26. The tightening band 4 can better wrap and limit the outer side of the goods, and is easy to adapt to goods of different shapes. The remaining slider nut bodies 23, according to the above method, move the remaining two ends of the slider nut bodies 23 away from the goods, further realizing the tightening operation of the tightening band 4. In the natural state, the return spring 2 When adjustment plate 252 is released, the return spring 242 can pull the connecting plate 243 to quickly reset, and the toothed block 244 will quickly push out into the toothed groove 3 at its corresponding position, which can quickly limit the position of the slider nut body 23. This adjustment method is convenient and efficient. The connecting plate 243 will push out to facilitate the next adjustment of the position of the slider nut body 23. The setting of the fixing hook 6 makes it easy to fix the nylon belt 7 to the upper surface of the goods, improving the stability of the goods. The limiting groove 27 opened in the inner corner area of ​​the triangular lifting ring 26 restricts the range of motion of the fixing hook 6, making the fixing hook 6 less likely to slide and improving the stability during transportation.

[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.
