Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides as Figures 1-5A cargo-fixing mechanism for logistics as shown includes a fixed bottom plate 1. Support side plates 2 are respectively installed on one side wall of the fixed bottom plate 1. A support main shaft 3 is rotatably connected to the support side plates 2. Fixed rollers 4 are installed on the side wall of the support main shaft 3. Fixed ratchets 5 are respectively installed at both ends of the support main shaft 3. Guide rods 6 are respectively installed on one side wall of the fixed bottom plate 1. The number of the guide rods 6 is two, and they are symmetrically installed on one side wall of the fixed bottom plate 1. A guide plate 7 is slidably clamped on the guide rods 6. Limit rods 8 are respectively installed on one side wall of the guide plate 7. The number of the limit rods 8 is two, and they are symmetrically installed on the guide plate 7. A compression spring 9 is arranged on the side wall of the guide rod 6. Guide shafts one 10 are respectively slidably clamped on the fixed bottom plate 1. A U-shaped frame 11 is installed at one end of the guide shaft one 10. A support roller 12 is rotatably connected to the U-shaped frame 11. A tightening screw one 13 is connected to the fixed bottom plate 1. A fixed groove 14 is formed on the fixed roller 4. Fixed screws 18 are respectively connected to the fixed roller 4. U-shaped seats 15 are respectively fixedly installed on one side wall of the fixed bottom plate 1. When fixing goods, first place one end of the bandage for binding the goods on one side of the support roller 12, then pass it through the U-shaped seat 15, and then through the fixed groove 14 on the fixed roller 4. By screwing the fixed screw 18, the end of the bandage can be tightened. Then rotate the support main shaft 3 to wind the binding band around the fixed roller 4, so as to adjust the tightness of the bandage. When the support main shaft 3 rotates, the fixed ratchets 5 at both ends will rotate simultaneously. And whenever the ratchet teeth on the fixed ratchet 5 pass through the limit rod 8, the compression spring 9 will drive the guide plate 7 to move, so as to drive the limit rod 8 to rebound in time to limit the ratchet teeth, avoiding the reverse rotation of the fixed ratchet 5, and thus preventing the reverse rotation of the fixed roller 4. Therefore, this cargo-fixing mechanism can conveniently and quickly adjust the bandage. And by screwing the tightening screw one 13 to drive the U-shaped frame 11 to move, the support roller 12 can press against the bandage, so as to further tighten the bandage, which is beneficial to improving the stability when the bandage fixes the goods. When disassembling, by reversing the tightening screw one 13, the support roller 12 no longer presses against the bandage, and the bandage can be loosened. When disassembling the bandage subsequently, it can prevent the problem that one end of the bandage is difficult to disassemble due to the tightness of the bandage. Guide shafts two 16 are respectively slidably clamped on the fixed bottom plate 1. A pressing plate 17 is installed at one end of the guide shaft two 16. A tightening screw two 19 is connected to the fixed bottom plate 1. A support spring two 23 is arranged on the side wall of the guide shaft two 16. When placing the bandage inside the U-shaped seat 15, by screwing the tightening screw two 19 to drive the pressing plate 17 to move, it can press against the bandage, so as to further fix the bandage. When disassembling, loosen the tightening screw two 19, and the pressing plate 17 can be driven to retract by the tightening screw two 19.

[0025] In this embodiment, a support spring one 22 is arranged on the side wall of the guide shaft one 10. When the tightening screw one 13 is loosened, the U-shaped frame 11 can be driven to retract by the support spring one 22.

[0026] In this embodiment, a handle 21 is installed at one end of the support main shaft 3. Through the handle 21, it is convenient to rotate the support main shaft 3.

[0027] In this embodiment, a support base 20 is fixedly installed on one side wall of the fixed base plate 1. Through the support base 20, the device can be connected to the vehicle body.

[0028] The working principle of this utility model: This utility model is a cargo fixing mechanism for logistics. One end of the bandage binding the goods is placed on one side of the support roller 12, then passes through the U-shaped seat 15, and finally passes through the fixing groove 14 on the fixed roller 4. By screwing the fixing screw 18, the bandage is tightened, and one end of the bandage is connected to the fixed roller 4. Then, the fixed roller 4 can be rotated to wind the binding belt around the fixed roller 4 to further tighten the bandage. And when the fixed roller 4 rotates, it will drive the fixed ratchet 5 to rotate forward. Whenever the ratchet teeth on the fixed ratchet 5 pass through the limit rod 8, the compression spring 9 will drive the guide plate 7 to move, so that the limit rod 8 can rebound in time to limit the ratchet teeth and prevent the fixed ratchet 5 from reversing, thereby preventing the fixed roller 4 from reversing, so that the cargo fixing mechanism can conveniently and quickly adjust the bandage.

[0029] By screwing the first tightening screw 13, it drives the U-shaped frame 11 to move, so that the support roller 12 can press against the bandage to further tighten the bandage, which is beneficial to improving the stability when the bandage fixes the goods. During disassembly, reverse the first tightening screw 13 so that the support roller 12 no longer presses against the bandage, thereby loosening the bandage and avoiding the problem that one end of the bandage is difficult to disassemble due to the tightness of the bandage during subsequent disassembly of the bandage.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
