[0033] Refer to the attached Figures 1-5, An overload tray, comprising a horizontal support rail 1. A vertical fixed slide rail 2 is provided on the top of the horizontal support rail 1. The vertical fixed slide rail 2 is detachably connected to a plurality of roller components 3. The roller components 3 are matingly connected to a moving slide rail 4. The top of the moving slide rail 4 is connected to a load-carrying tray 5. The load-carrying tray 5 is smaller at the front and larger at the rear, and is designed to fit along the inner edge of the truck bed. The load-carrying tray 5 is slidably connected to the vertical fixed slide rail 2 through the moving slide rail 4. When the device works, first weld or screw-connect the horizontal support rail 1 at the bottom to the bottom of the truck bed, and then connect the vertical fixed slide rail 2 to the horizontal support rail 1 at the bottom. The cross arrangement design of the horizontal support rail 1 and the vertical fixed slide rail 2 can make the pressure of the top load-carrying tray 5 on the bottom of the truck bed more uniform. Subsequently, install the roller components 3 on the vertical fixed slide rail 2, insert the moving slide rail 4 into the vertical fixed slide rail 2 and matingly connect it to the roller components 3, and finally connect the load-carrying tray 5 to the moving slide rail 4 to complete the final installation. Among them, the load-carrying tray 5 can move along the vertical fixed slide rail 2, which is convenient for taking and placing items on the top of the load-carrying tray 5.

[0034] Please refer to Figure 5 , The vertical fixed slide rail 2 includes symmetrically arranged sliding support members 21. The middle parts of the sliding support members 21 are integrally formed through a connecting plate 22. A first convex chute 23 is opened inside the sliding support member 21. A concave structure cavity 24 is provided at the bottom and the outside of the first convex chute 23. The first convex chute 23 is detachably connected to the roller component 3 by screws. A square space 25 formed between the two sliding support members 21 slidably connects the moving slide rail 4. As a support component for the top load-carrying tray 5, the vertical fixed slide rail 2 needs to have strong structural stability. The two symmetrically arranged first convex chutes 23 can be well detachably connected to the roller components 3, and it is also convenient for the roller components 3 to adjust their positions in the first convex chutes 23. The connecting plate 22 improves the pressure-bearing capacity at the bottom. The two concave structure cavities 24 can improve the structural strength while reducing the overall weight.

[0035] Please refer to Figure 5 , The roller component 3 includes a sliding connection block 31. The sliding connection block 31 is slidably connected inside the first convex chute 23. A first connection hole 32 is opened on the side of the sliding connection block 31. The first connection hole 32 is detachably connected to a vertical rotating wheel 33. The vertical rotating wheel 33 is slidably connected to the moving slide rail 4. The roller component 3 is a support component that facilitates the movement of the moving slide rail 4. A plurality of first connection holes 32 are provided according to the sliding requirements, and a plurality of vertical rotating wheels 33 are connected according to the length of the top moving rail. When the top moving slide rail 4 moves, the vertical rotating wheels 33 facilitate its lateral sliding. In this embodiment, the number of vertical rotating wheels 33 is three.

[0036] Please refer to Figure 5, the first connection hole 32 is threadedly connected to the first convex sliding groove 23 by screws. In this embodiment, multiple roller skating assemblies 3 are provided according to the load requirement, facilitating the movement operation of the top moving slide rail 4. To improve the stability of the top load-carrying tray 5, the roller skating assemblies 3 are evenly distributed within the first convex sliding groove 23.

[0037] Please refer specifically to Figure 5 , the first connection hole 32 is connected to the concave support block 34. The concave support block 34 is internally rotatably connected to the transverse guide wheel 35. To improve the stability when the top moving slide rail 4 moves, multiple transverse guide wheels 35 are designed, which can cooperate with the top moving slide rail 4 to enable the moving slide rail 4 to move along a straight line. In this embodiment, one transverse guide wheel 35 is provided.

[0038] Please refer specifically to Figure 5 , the moving slide rail 4 includes an I-shaped support plate 41. Second convex sliding grooves 42 are symmetrically formed on both sides of the I-shaped support plate 41. Concave sliding grooves 43 are symmetrically provided at the top of the I-shaped support plate 41. A slider nut is provided within the concave sliding groove 43, and the slider nut is matingly connected to the load-carrying tray 5. The two second convex sliding grooves 42 of the moving slide rail 4 can slide under the support of the vertical rotating wheels 33. The middle position of the I-shaped support plate 41 is located between two symmetrically arranged transverse guide wheels 35, facilitating the linear movement of the moving slide rail 4. The top concave sliding groove 43 is connected to the load-carrying tray 5 through the slider nut.

[0039] Please refer specifically to Figure 5 , the load-carrying tray 5 includes symmetrically arranged first support frames 51. An installation groove 52 is formed inside the first support frames 51. The installation groove 52 is matingly connected to the load-carrying plate 53. A second support frame 54 is provided at the rear end of the first support frames 51. Second connection holes 55 are formed on the load-carrying plate 53, and the second connection holes 55 are connected to the slider nuts within the concave sliding grooves 43 by screws. After the load-carrying plate 53 is inserted into the installation groove 52 of the first support frames 51, the load-carrying plate 53 is connected to the bottom moving slide rail 4 through the second connection holes 55. Finally, the second support frame 54 is used to connect and lock the edge load-carrying plates 53. When in use, pulling the second support frame 54 outwards can drive the first support frames 51 and all the load-carrying plates 53 to move along with the moving slide rail 4.

[0040] In this embodiment, the first support frames 51, the second support frames 54, and the load-carrying plates 53 are made of aluminum profiles. It should be noted that using aluminum profiles in this embodiment can achieve the effects of being lightweight and having good structural strength, which can ensure a certain supporting force while reducing the weight. Of course, other sheet metal materials can also be used to adapt to different loading situations.

[0041] The above-described embodiments merely represent certain implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
