Logistics is the whole process of planning, implementing and managing the raw materials, semi-finished products, finished products and related information from the place of production to the place of consumption of goods through transportation, storage, distribution and other means at the lowest cost to meet customer needs.

[0003] In the process of logistics transportation, there are many varieties of goods. Some goods require specific cargo boxes and shelves to protect them due to their characteristics and shapes. Among them, glass transport racks are indispensable in the transportation of glass goods. Glass transport racks are also called A-shaped racks. The glass is placed on both sides of the transport rack and then fixed with ropes for transportation.

[0004] However, in the traditional rope fixing method, the rope needs to be manually knotted, which is cumbersome and inevitably bumpy during transportation. The rope buckle is at risk of loosening, causing the glass to slide. Based on this, a protective device for cargo transportation is provided. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 6 In the embodiment of the utility model, a protective device for cargo transportation includes a transport frame 1, a rotating groove 8 is arranged inside the upper end of the transport frame 1, a ratchet mechanism 2 is arranged on one side of the upper end of the transport frame 1, and the ratchet mechanism 2 includes a ratchet 201, a pawl 202, a limit plate 203, and a spring 204:

[0027] The ratchet 201 is rotatably connected to the outer wall of one side of the transport frame 1, the pawl 202 is rotated above the ratchet 201 and meshes with the ratchet 201, the limit plate 203 is fixedly connected to the outer wall of the transport frame 1 away from the pawl 202, a rotating shaft is arranged at the center of the ratchet 201, the rotating shaft penetrates into the interior of the rotating groove 8, and the clockwork spring 204 is sleeved on the outer wall of the rotating shaft;

[0028] A fixing belt 3 is fixedly connected to the outer wall of the rotating shaft on the side away from the clockwork spring, and a fixing head 4 is fixedly connected to one end of the fixing belt 3;

[0029] A clamping mechanism 5 is provided at one end of the transport frame 1, and the clamping mechanism 5 includes a fixing seat 501, a clamping head 502, a first spring 503, a second spring 504, and a switch lock 505;

[0030] The fixing seat 501 is slidably connected to the upper surface of the transport frame 1, the second spring 504 is fixedly connected to one side of the inner cavity of the fixing seat 501, the engaging head 502 is rotatably connected to the inside of the fixing seat 501, and the bottom of one side of the engaging head 502 is in contact with the top of the second spring 504, the switch lock 505 is slidably connected to the upper end of the fixing seat 501 and extends downward to the upper end of one side of the engaging head 502, and the first spring 503 is installed inside the fixing seat 501 and is located at the bottom of the other side of the engaging head 502;

[0031] The locking mechanism 5 further includes a fixing bolt 506, which is threadedly connected to the upper surface of the sliding block 507 and extends downward to fit with the bottom of the sliding slot 6;

[0032] The fixing head 4 is provided with fixing holes 7 on both sides, and the size of the fixing holes 7 matches the protrusion at one end of the snap-fit ​​head 502.

[0033] In this embodiment, when the glass needs to be transported, the glass is placed on the upper surface of the base of the transport rack 1, the fixing seat 501 is slid and adjusted to the position of the glass thickness, the fixing bolt 506 is rotated to fix the fixing seat 501, the pawl 202 is rotated to the upper surface of the limit plate 203, the fixing belt 3 is pulled, and the fixing head 4 is inserted into the inside of the fixing seat 501.
