[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, the pull-out container of one embodiment of the present invention comprises an outer box 1, a slide rail assembly 2 and an inner box 3. Figures 2 to 4As shown, the slide rail assembly 2 includes a first slide rail 21, a second slide rail 22, and a third slide rail 23. The first slide rail 21 is disposed on the inner wall of the outer box 1, and the third slide rail 23 is disposed on the outer wall of the inner box 3. One end of the second slide rail 22 is slidably connected to the first slide rail 21, and the other end of the second slide rail 22 is slidably connected to the third slide rail 23. The first slide rail 21 and the second slide rail 22 are arranged in pairs. The first slide rail 21 has a first slide groove 211, and the second slide rail 22 has a second slide groove 221. The second slide rail 22 also has a first slide post 24, and the third slide rail 23 has a second slide post 25. The first slide post 24 can slide in the first slide groove 211, and the second slide post 25 can slide in the second slide groove 221, thereby achieving the extension and retraction of the entire slide rail assembly 2.

[0028] like Figure 4 As shown, the bottom of the inner box 3 includes multiple pairs of discharge doors 31, each pair of discharge doors 31 includes a left door panel 311 and a right door panel 312. The sides of the left door panel 311 and the right door panel 312 that are away from each other are hinged to the side wall of the inner box 3, and the sides of the left door panel 311 and the right door panel 312 that are close to each other are provided with a positioning ring 313. Figure 1 As shown, the positioning ring 313 is used for inserting the positioning rod 314 to close the discharge door 31.

[0029] When loading is required, the inner box 3 is pulled out from the inside of the outer box 1, and the unloading door 31 at the bottom of the inner box 3 is kept closed to load the materials. After loading is completed, the inner box 3 is stuffed back into the outer box 1 for transportation. When unloading is required, the inner box 3 is first pulled out from the inside of the outer box 1, and then the positioning rod 314 is pulled out from the positioning ring 313 to open each unloading door 31. The materials in the inner box 3 fall out by themselves under the action of gravity, and the unloading efficiency is high. After unloading is completed, the positioning rod 314 is inserted into each positioning ring 313, and each unloading door 31 is closed, and the inner box 3 is pushed back into the inside of the outer box 1. The pull-out cargo box of the utility model has a simple structure and is easy to use. It adopts a pull-out design and can be placed on a vehicle 100 such as a pickup truck, so that the vehicle 100 such as a pickup truck can be used for loading, unloading and transportation of materials such as slag and mud, and will not cause pollution to the vehicle 100 such as the pickup truck. It is low in cost and does not require the purchase of a dedicated transport vehicle.

[0030] like Figure 5 As shown, in this embodiment, the edges of two adjacent discharge doors 31 overlap, similar to the arrangement of roof tiles. This provides support for the adjacent discharge door 31 and prevents large gaps between adjacent discharge doors 31, minimizing material leakage. When the positioning rod 314 is removed, each discharge door 31 opens one by one, reducing the difficulty of opening the discharge door 31.

[0031] like Figure 1 、 Figure 6 and Figure 7 As shown, the pull-out cargo box further includes a support assembly 4, which includes a support rod 41, a positioning cylinder 42, and a limiting plate 43. One end of the positioning cylinder 42 is provided with a positioning hole (not shown in the figure) for inserting one end of the support rod 41. The positioning cylinder 42 is rotatably mounted on one end of the inner box 3. The limiting plate 43 is provided with a limiting groove (not shown in the figure) for the support rod 41 to pass through. The limiting plate 43 is detachably mounted on one end of the inner box 3 and is located below the positioning cylinder 42. When the inner box 3 is filled with materials, it is heavy. When the inner box 3 is pulled out, if it is not supported, the entire pull-out cargo box may tip over or fall. The support assembly 4 in this embodiment is used as follows: flip the positioning cylinder 42 so that the positioning hole is facing horizontally, insert one end of the support rod 41 into the positioning hole, and slowly adjust the support rod 41 from the horizontal direction to the vertical direction so that the end of the support rod 41 away from the positioning cylinder 42 touches the ground. Then, install the limit plate 43 to press the support rod 41 to prevent it from rotating further. When the support rod 41 needs to be removed, first remove the limit plate 43, then rotate the support rod 41 to extract it from the positioning cylinder 42. The support assembly 4 has a simple overall structure, high reliability, and is easy to use. It can support the inner box 3 and prevent the entire pull-out cargo box from tipping over.

[0032] Furthermore, the support assembly 4 also includes a connecting plate 44, a rotating shaft 45, and a shaft seat 46. Positioning cylinders 42 are provided on both sides of the connecting plate 44. The rotating shaft 45 is arranged horizontally, and a shaft seat 46 is provided at each end of the rotating shaft 45. The shaft seat 46 is fixed to one end of the inner box 3, and the connecting plate 44 is mounted on the rotating shaft 45. Because the supporting effect of a single support rod 41 is limited, the support assembly 4 of this embodiment includes two support rods 41, and the two positioning cylinders 42 are connected as a whole by a connecting plate 44. With the help of the rotating shaft 45 and the shaft seat 46, the entire assembly can be flipped and maintained synchronously.

[0033] like Figure 6 and Figure 7 As shown, the support assembly 4 also includes a fixing pin 47 and a latch seat 48. The latch seat 48 is fixedly mounted at one end of the inner box 3. The fixing pin 47 can be inserted into the latch seat 48 to secure the limit plate 43 to the end of the inner box 3. The fixing pin 47 is T-shaped. Once inserted into the latch seat 48, it is not easily loosened, allowing the limit plate 43 to press against the support rod 41. When the limit plate 43 needs to be removed, it only needs to pull out the fixing pin 47, which is very convenient.

[0034] In this embodiment, the end of the support rod 41 that contacts the ground is provided with a support wheel 49. When the support rod 41 changes from a horizontal state to a vertical state, the support wheel 49 contacts and slides with the ground, reducing friction, thereby facilitating adjustment of the support rod 41 to a vertical support state.

[0035] like Figure 1 and Figure 7 As shown, three horizontal placement tubes 32 are provided on the side wall of the inner box 3, and the placement tubes 32 are for inserting the support rods 41. By providing the placement tubes 32, the support rods 41 can be accommodated, and the space between the outer box 1 and the inner box 3 is cleverly utilized, making the pull-out cargo box more convenient to use.

[0036] like Figure 1 and Figure 7 As shown, a locking pin 33 is provided at one end of the inner box 3, and a locking hook 11 is provided on the surface of the outer box 1. The locking pin 33 is detachably connected to the locking hook 11. When the inner box 3 is inserted into the outer box 1, the locking pin 33 cooperates with the locking hook 11 to prevent the inner box 3 from slipping out of the outer box 1 and causing an accident, thereby improving safety.

[0037] like Figure 1 and Figure 7 As shown, a first buffer seat 12 is provided at one end of the outer box 1, and a second buffer seat 34 is provided at one end of the inner box 3. The first buffer seat 12 and the second buffer seat 34 are respectively provided at both ends of the pull-out cargo box. The first buffer seat 12 and the second buffer seat 34 can absorb shock and reduce the impact force when the pull-out cargo box and the carrier 100 are displaced, thereby protecting both the pull-out cargo box and the carrier 100.

[0038] like Figure 1 As shown, a plurality of rollers 13 are provided at the bottom of the outer box 1, so that the pull-out cargo box can be placed on the carrier 100 more conveniently. In order to prevent the pull-out cargo box from sliding after being placed, a stop block 5 is provided on one side of the roller 13.

[0039] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist.
