Even the goods that lose flexibility on the ground, immediately obtain activity and become flexible flow goods when being loaded on the tray, because the goods loaded on the tray are in the preparation state of motion at any time.

[0003] In the prior art tray field, most trays show relatively simple structural features. From the structural design point of view, the conventional tray often only has a basic bearing plane and a simple support component. For example, the common tray is only composed of a single flat tray body and a small amount of support feet or support strips at the bottom. The simple structural design determines the limitation of its function. When bearing articles, they mainly rely on the strength of the tray body itself to bear the weight, lack effective internal reinforcing structure, and cannot guarantee the stability of bearing. More importantly, the tray in the prior art has obvious deficiencies in article protection. These trays mostly do not have mechanisms specially designed to protect the articles placed thereon. During transportation or storage, the articles are only placed on the plane of the tray without any protective measures. In complex use environment, it is difficult to guarantee the integrity of the articles. SUMMARY

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0025] Referring to Figures 1-5

[0026] A stable load-bearing tray is mainly composed of a tray body 1, a support seat 2, an opening 3, a folding plate 5, a screw rod 8, a lifting frame 11, a stabilizing leg 7 and the like. The tray body 1 serves as the basic structure of the entire tray and bears the weight of the objects placed thereon. A plurality of support seats 2 are installed at the bottom of the tray body 1, which are evenly distributed at the bottom of the tray body 1 to provide stable initial support for the tray, so that the tray can maintain balance and stability when placed on a plane, ensuring the safety of the objects on the tray.

[0027] The tray body 1 is internally provided with a cavity, which plays a key role in the stability and functionality of the tray. A plurality of reinforcing rods 13 are arranged in the cavity, which are distributed in the cavity in a crisscross manner, like the "skeleton" of the tray. They enhance the structural strength of the tray body 1, so that the tray can effectively disperse pressure when bearing heavy objects and prevent the tray body 1 from deforming or being damaged due to excessive stress.

[0028] A plurality of openings 3 communicating with the cavity are provided at the upper end surface of the tray body 1, which are important parts for realizing the special functions of the tray. A folding plate 5 is rotatably arranged in each opening 3 through a blocking mechanism. Specifically, the blocking mechanism includes a baffle 4 arranged in the opening 3, which is fixedly installed in the opening 3. The baffle 4 provides a support point for the folding plate 5 and can stably realize the folding and unfolding actions. The folding plate 5 can be stored in the opening 3 when not in use, and can be unfolded by rotating around the connecting point with the baffle 4 when in use.

[0029] A screw rod 8 is arranged in the cavity through a supporting mechanism. The supporting mechanism comprises a supporting frame 9 mounted in the cavity, and the screw rod 8 is rotationally connected with the supporting frame 9. The supporting frame 9 provides stable support for the screw rod 8, so that the screw rod 8 will not deviate or shake during rotation, thereby ensuring the stability of the entire transmission system. A power mechanism connected with the screw rod 8 is further arranged in the cavity, and the power mechanism comprises a driving motor 10 arranged in the cavity. The output shaft of the driving motor 10 is fixedly connected with the end of the screw rod 8. When the driving motor 10 is started, it can convert electrical energy into mechanical energy to drive the screw rod 8 to rotate, thereby providing a power source for subsequent lifting actions.

[0030] A lifting frame 11 is threadedly arranged on the screw rod 8 through a limiting mechanism. The limiting mechanism comprises a limiting rod 12 mounted in the cavity, and the limiting rod 12 is parallel to the screw rod 8 and slidably penetrates the lifting frame 11. The limiting rod 12 plays a limiting and guiding role in the movement of the lifting frame 11. When the screw rod 8 rotates, the lifting frame 11 can only move up and down along the axial direction of the screw rod 8 due to the limitation of the limiting rod 12, thereby avoiding the self-rotation of the lifting frame 11 and other unstable conditions caused by the rotation of the screw rod 8. A plurality of stable legs 7 extending to the lower side of the tray body 1 are mounted on the lifting frame 11. When the lifting frame 11 descends, the stable legs 7 gradually extend to the lower side of the tray body 1 and contact the ground, thereby providing an additional support point for the tray and further enhancing the stability of the tray.

[0031] The lifting frame 11 is connected with the folding plate 5 through a transmission mechanism. The transmission mechanism comprises a rack 6 mounted on the lifting frame 11, and a gear 14 mounted on the folding plate 5. The rack 6 is engaged with the gear 14. When the lifting frame 11 moves up and down under the driving of the screw rod 8, the rack 6 moves along with it, and the linear motion of the lifting frame 11 is converted into the rotary motion of the folding plate 5 through the engagement with the gear 14. This ingenious transmission design makes the lifting of the stable legs 7 and the unfolding or folding of the folding plate 5 interrelated, realizes the integrated operation of the tray structure, and improves the convenience and functionality of the tray.

[0032] When the tray body 1 is used, it is placed on a plane through the uniformly distributed supporting seats 2 at the bottom, thereby providing initial stable support for the tray body 1 and ensuring the safety of the placed articles. The longitudinally and transversely intersecting reinforcing rods 13 in the cavity of the tray body 1 enhance the structural strength of the tray body 1, can effectively disperse the weight pressure, and avoid deformation and damage of the tray body 1.

[0033] In the operation process, when the driving motor 10 in the starting cavity, the driving motor 10 output shaft with fixed connection of the screw 8 rotation. Screw 8 in the stable support of support frame 9 under the rotation, lifting frame 11 in the screw 8 rotation along the screw 8 axial movement. With the lifting frame 11 down, installed on its stable leg 7 gradually extended tray body 1 below, with the ground contact, increase the support point of tray body 1, enhance the stability.

[0034] At the same time, the movement of lifting frame 11 through the transmission mechanism influence folding plate 5 state. Rack 6 installed on the lifting frame 11 up and down motion, rack 6 with the gear 14 installed on the folding plate 5 meshing, thus the linear motion of lifting frame 11 into the rotating motion of folding plate 5.

[0035] Lifting frame 11 down makes the stable leg 7 stretch out at the same time, folding plate 5 around the opening 3 in the baffle 4 on the connecting point rotation unfolded, when the folding plate 5 unfolded vertical state, can play the role of protection placed in the tray body 1 goods, realize the function of protecting goods, and through the integrated design improves the convenience and functionality of tray use.

[0036] The above, only for the preferred specific embodiments of the present application, but the scope of the present application is not limited to this, any skilled in the art of the technical personnel in the present application disclosed in the technical range, according to the technical scheme of the present application and the utility model concept of equivalent replacement or change, should be covered in the scope of the present application.
