[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown in the figure, this utility model embodiment proposes an auxiliary loading and unloading structure for a cargo box, installed on the cargo box body 1, including:

[0024] Mounting plate 3, two mounting plates 3 are mirror-distributed at the bottom of the cargo box body 1;

[0025] A support plate 2 is located between two mounting plates 3. Both mounting plates 3 are provided with grooves 301. The end of the support plate 2 is provided with a mounting shaft 4. The mounting shaft 4 is slidably disposed between the two grooves 301. The mounting plate 3 is bent inward to form a support part 303. One end of the support part 303 has a notch 304. When the mounting shaft 4 slides to the groove 301 and corresponds to the notch 304, the end of the support plate 2 away from the mounting shaft 4 tilts downward.

[0026] In the embodiments of this utility model, by installing two mounting plates 3 in a mirror manner to the bottom end of the cargo box body 1, the bottom space of the cargo box body 1 is fully utilized, and the support plate 2 is installed in the sliding groove 301 of the two mounting plates 3 through the mounting shaft 4. At the same time, when the support plate 2 is located at the bottom end of the cargo box body 1, the support plate 2 is supported by the support part 303 to be parallel to the cargo box body 1. In the storage state, the support plate 2 is stored at the bottom end of the cargo box body 1 to ensure the stability of the cargo box body 1.

[0027] When moving larger objects into the cargo box 1, the support plate 2 and the two mounting plates 3 work together to pull out the entire support plate 2 located between the two mounting plates 3. This allows the mounting shaft 4 of the support plate 2 to slide in the groove 301 of the mounting plate 3 until the mounting shaft 4 moves to the notch 304 of the support part 303. This releases the support part 303 from the support plate 2, causing the support plate 2 to rotate around the mounting shaft 4. The end of the support plate 2 then touches the ground, allowing the support plate 2 to be erected between the cargo box 1 and the ground. This facilitates movement of the handler on the support plate 2, or the support and movement of goods. It makes it easy for handlers to move larger objects into the cargo box 1 without the need for other auxiliary tools, which is not only efficient but also ensures the safety of the handlers. After the subsequent handling work is completed, the support plate 2 can be pushed back between the two mounting plates 3 and stored at the bottom of the cargo box 1 for future use.

[0028] Based on the above solutions, such as Figure 3As shown, it also includes a fixing bracket 6. The end of the mounting shaft 4 is provided with a mounting hole 401. The fixing bracket 6 is slidably inserted through the mounting hole 401. The end of the mounting plate 3 away from the notch 304 is provided with a fixing hole 307. The fixing bracket 6 is provided with a fixing pin 7. When the mounting shaft 4 moves to the end of the slide groove 301 near the fixing hole 307, the fixing pin 7 is inserted through the fixing hole 307 to fix the mounting shaft 4.

[0029] To ensure that the stowed support plate 2 does not detach from the bottom of the cargo box body 1 during the truck's movement, Figure 1 For example, when the mounting shaft 4 of the support plate 2 moves to the leftmost end of the slide 301, the mounting shaft 4 drives the fixing bracket 6 to move in the slide 301, so that the fixing pin 7 of the fixing bracket 6 corresponds to the fixing hole 307 of the mounting plate 3. At the same time, when the fixing bracket 6 can move back and forth in the mounting hole 401, by pressing the fixing bracket 6, the fixing pin 7 set in the fixing bracket 6 is directly inserted into the fixing hole 307, which can fix the mounting shaft 4 to the leftmost end of the slide 301, thereby preventing the support plate 2 from falling out of the cargo box body 1 during the movement of the truck, ensuring safety.

[0030] Meanwhile, a spring 5 is provided in the mounting hole 401, which abuts against the end of the fixing bracket 6 and the inner side of the mounting hole 401. The spring 5 can provide a certain rebound force to the fixing bracket 6, ensuring that the fixing bracket 6 is always subjected to the inward force applied by the spring 5, thus ensuring that the fixing pin 7 is always in the fixing hole 307, guaranteeing the stability of the mounting shaft 4, and further improving the stability of the support plate 2 after it is stored. When moving the support plate 2, the fixing bracket 6 is pulled, causing the fixing bracket 6 to compress the spring 5 and simultaneously pull the support plate 2, allowing the fixing pin 7 to shift away from the fixing hole 307, after which the fixing bracket 6 can be released.

[0031] Based on the above solutions, such as Figure 2 As shown, the support plate 2 includes a fixed plate 201 and a movable plate 202, with the movable plate 202 slidably mounted on the support plate 2. To increase the overall area of ​​the support plate 2, the fixed plate 201 is connected to the mounting shaft 4. When the mounting shaft 4 moves to the rightmost end of the slide groove 301, the fixed plate 201 can swing downwards under the action of gravity. At the same time, it pulls the movable plate 202 stored in the fixed plate 201, causing the movable plate 202 to move out of the fixed plate 201. This ensures a small storage area while increasing the usable space of the support plate 2. When one end of the movable plate 202 touches the ground, the angle between the cargo box body 1 and the support plate 2 increases, reducing the slope of the support plate 2 and making it easier for operators to walk on it or for goods to move on the support plate 2.

[0032] Specifically, such as Figure 2As shown, the fixed plate 201 has a movable groove 203, and the movable plate 202 has a movable block 204 that is engaged with the movable groove 203. The movable block 204 is threadedly connected with a clamping bolt 205. The end of the clamping bolt 205 extends through the movable plate 202 and abuts against the inner side of the fixed plate 201. When the movable plate 202 moves within the fixed plate 201, it causes the movable plate 202 to drive the movable block 204 to move within the movable groove 203. To ensure the stability of the movable plate 202 after it extends out of the fixed plate 201, the clamping bolt 205 is rotated so that the end of the clamping bolt 205 abuts against the inner side of the fixed plate 201, thereby fixing the movable plate 202 and ensuring the stability of the fixed plate 201 and the movable plate 202 after they extend.

[0033] Specifically, such as Figure 2 As shown, the end of the movable plate 202 is provided with an inclined surface 206; when the end of the movable plate 202 abuts against the ground, the inclined surface 206 abuts against the ground, increasing the contact area between the movable plate 202 and the ground, and ensuring the stability of the support plate 2.

[0034] Specifically, such as Figure 4 As shown, a groove 302 is provided at one end of the slide groove 301 near the notch 304; when the mounting shaft 4 slides to the end of the slide groove 301 near the notch 304, the mounting shaft 4 is engaged in the groove 302, which ensures the stability of the support plate 2 during operation and prevents it from sliding.

[0035] like Figure 4 As shown, the mounting plate 3 is bent outward to form a mounting part 305, and the mounting part 305 has several assembly holes 306. In order to facilitate assembly, the mounting part 305 can be attached to the bottom of the cargo box body 1 and then fastened with screws. This not only facilitates the initial assembly, but also facilitates the subsequent disassembly and maintenance.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
