Description

Technical Field

[0001] This utility model relates to the field of canopy technology, and in particular to a lifting component and a canopy-covered food truck body. Background Technology

[0002] In the food transportation sector, food trucks, as a common mode of transport, play a crucial role in transporting various foods from production sites to sales locations. During transportation, to ensure food quality and safety and avoid the impact of external environmental factors such as rain, dust, and direct sunlight, equipping food trucks with covered cargo boxes is particularly necessary.

[0003] Existing food truck canopy-equipped body structures vary, but they generally have some shortcomings. The height adjustment of the canopy in some canopies is not flexible enough, making it difficult to adapt to different usage scenarios and transportation needs. For example, during loading and unloading, the canopy height may need to be adjusted according to the actual situation to facilitate cargo handling; while during driving, it is necessary to ensure the canopy is at a suitable height to guarantee safety and stability. Furthermore, the deployment and retraction of some canopies are cumbersome, increasing the workload and time cost for operators. Therefore, we propose a lifting component and a food truck canopy-equipped body to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inflexible height adjustment of the canopy of the cargo box, which makes it difficult to adapt to different usage scenarios and transportation needs, and the cumbersome operation of unfolding and retracting the canopy, which increases the difficulty of the operator's work. Therefore, this invention proposes a lifting component and a cargo box with a canopy for food trucks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lifting assembly includes two base boxes, with a Z-shaped frame slidably connected inside each base box. The top of the Z-shaped frame extends above the base box. Two adjusting screws are symmetrically arranged inside the base box. The top and bottom ends of the adjusting screws are rotatably connected to the top and bottom inner walls of the base box, respectively, via bearings. Two adjusting nuts are symmetrically welded to the bottom of the Z-shaped frame. The adjusting screws pass through the corresponding adjusting nuts and the Z-shaped frame, and are threadedly connected to the adjusting nuts.

[0007] In one possible design, a handwheel ring is fixedly fitted onto the adjusting screw by adhesive, and the handwheel ring is located below the adjusting nut.

[0008] A food truck body with a rain canopy includes the lifting assembly described above, as well as a mounting frame and a connecting frame. The mounting frame is welded to the top of two Z-shaped frames, and the connecting frame is welded to the top of two Z-shaped frames, with the connecting frame located on one side of the mounting frame. A tarpaulin is bolted to one side of the mounting frame, and multiple keel frames are evenly spaced and sewn onto the tarpaulin. A support assembly is mounted on the top of the Z-shaped frames, and the bottom sides of the keel frames are connected to corresponding support assemblies. The rain canopy body also includes:

[0009] The drive mechanism is installed on the top of the mounting frame and the top of the connecting frame. The drive mechanism is connected to the keel frame furthest from the mounting frame and can drive the tarpaulin to expand or contract.

[0010] In one possible design, the support assembly includes a ground rail welded to the top of the Z-shaped frame, a limit rod welded inside the ground rail, multiple sliding plates slidably mounted on the limit rod, and the bottom side of the keel frame welded to the corresponding sliding plate.

[0011] In one possible design, side slide rails are welded to both sides of the mounting frame, one side of the side slide rail is welded to the side corresponding to the connecting frame, and limit plates are welded to both sides of the keel frame, one side of the limit plate extends into the side slide rail and slides in connection with the inner wall of the side slide rail.

[0012] In one possible design, the drive mechanism includes a connecting plate welded to the top of the mounting frame and the top of the connecting frame, respectively. A handwheel lever is rotatably connected through the connecting plate, with the bottom end of the handwheel lever extending into the mounting frame. A support shaft is rotatably connected to the top of the connecting plate. The same transmission assembly is connected to the support shaft and the handwheel lever. The bottom of the transmission assembly is connected to the top of the keel frame furthest from the mounting frame.

[0013] In one possible design, the transmission assembly includes two synchronous pulleys, which are fixedly mounted on the handwheel lever and the support shaft by key connection. The same synchronous belt is mounted on the two synchronous pulleys. An L-shaped fixing plate is fixedly installed on one side of the synchronous belt by bolt connection. The bottom of the L-shaped fixing plate is welded to the top of the keel frame furthest from the mounting frame.

[0014] In one possible design, a baffle is welded to one side of the L-shaped fixing plate, and a guide rail is slidably fitted onto the baffle. The guide rail is welded to the top of the mounting frame and the top of the connecting frame, respectively.

[0015] In one possible design, the top of the mounting bracket and the top of the connecting bracket are also bolted together with the same cover plate, which covers the connecting plate, two synchronous pulleys, synchronous belt, L-shaped fixing plate and stop rail.

[0016] In this application, the technical solution involves first gripping the handwheel and rotating it clockwise. The handwheel drives the adjusting screw to rotate synchronously, and the adjusting nut and adjusting screw are threaded together, driving the Z-shaped frame to slide longitudinally along the inner wall of the base box. This allows for adjustment of the canopy height, enabling the canopy height to be adjusted according to actual needs during food transportation. When the canopy reaches the desired height, the handwheel is stopped, and the Z-shaped frame is fixed in position. The canopy is then confirmed to be in the retracted state, with the keel frame close to the mounting frame. At this point, the food goods to be transported can be placed on the food cart. After the food goods are loaded, the operator can rotate the handwheel clockwise. The handwheel drives the synchronous pulley to rotate, and the synchronous belt moves under the drive of the synchronous pulley. The L-shaped fixing plate moves with the synchronous belt, causing the furthest keel frame to slide along the side rail and ground rail. The keel frame sequentially pulls the canopy, achieving overall canopy deployment. When the canopy is fully deployed, the handwheel is stopped.

[0017] When the tarpaulin needs to be retracted, the handwheel can be turned counterclockwise. The synchronous wheel drives the synchronous belt to move in the opposite direction, and the L-shaped fixing plate moves with the synchronous belt, pushing the farthest keel frame to slide in the opposite direction along the side rail and the ground rail. The keel frame folds the tarpaulin in sequence, realizing the overall retraction of the awning. When the awning is fully retracted, stop turning the handwheel.

[0018] Beneficial effects: In this utility model, the food truck with a rain canopy body can be slidably connected by a support component, a ground rail, a limiting rod and a sliding plate to provide lateral sliding support for the keel frame, thereby enabling lateral movement of the keel frame;

[0019] In this utility model, the food truck with a rain canopy body is driven by a drive mechanism. By operating the handwheel lever, the transmission component is moved under the support of the support shaft. When the transmission component moves, the keel frame furthest from the mounting frame moves, thereby enabling the canopy to be unfolded or retracted.

[0020] This invention improves upon existing awnings by allowing for height adjustment, enabling adjustments to be made as needed when transporting different goods. Furthermore, the awning can be easily retracted or expanded, thus providing excellent ease of use. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1: Refer to Figure 4 A lifting assembly includes two base boxes 1. Two adjusting screws 2 are symmetrically installed inside the base boxes 1. The top and bottom ends of the adjusting screws 2 are rotatably connected to the top and bottom inner walls of the base box 1 respectively via bearings, allowing the adjusting screws 2 to rotate smoothly. A Z-shaped frame 3 is slidably connected inside the base boxes 1, with its top extending above the base boxes 1. Two adjusting nuts 4 are symmetrically welded to the bottom of the Z-shaped frame 3, allowing the adjusting screws 2 to pass through the corresponding adjusting nuts 4 and the Z-shaped frame 3, and be threadedly connected to the adjusting nuts 4. When the adjusting screws 2 rotate, due to the threaded transmission, the adjusting nuts 4 drive the Z-shaped frame 3 to move longitudinally within the base boxes 1, thereby adjusting the longitudinal height of the Z-shaped frame 3. A handwheel ring 5 is glued and fixedly fitted onto the adjusting screws 2, with the handwheel ring 5 located below the adjusting nuts 4. The operator pushes the handwheel ring 5 to rotate the adjusting screws 2, thereby driving the Z-shaped frame 3 to rise or fall, making operation convenient.

[0029] Example 2: Reference Figure 1-5A container body includes a mounting frame 6 and a connecting frame 7 welded to the top of two Z-shaped frames 3, with the connecting frame 7 located on one side of the mounting frame 6. A tarpaulin 12 is bolted to one side of the mounting frame 6, and multiple keel frames 11 are stitched together at equal intervals on the tarpaulin 12. A support assembly is provided on the top of the Z-shaped frames 3, including a ground rail 8 welded to the top of the Z-shaped frames 3, a limiting rod 9 welded inside the ground rail 8, and multiple sliding plates 10 slidably mounted on the limiting rod 9. One side of the bottom of each keel frame 11 is welded to a corresponding sliding plate 10. The keel frame 11 can slide laterally along the ground rail 8 on the limiting rod 9 via the sliding plates 10, achieving lateral movement of the keel frame 11 and providing lateral sliding support. Side rails 13 are welded to both sides of the mounting frame 6, with one side of each side rail 13 welded to the corresponding side of the connecting frame 7. Limiting plates 14 are welded to both sides of the keel frame 11. One side of the limiting plate 14 extends into the side slide rail 13 and slides in connection with the inner wall of the side slide rail 13, thereby providing horizontal sliding support for the keel frame 11 and ensuring its lateral linear movement. A drive mechanism is installed on the top of the mounting frame 6 and the top of the connecting frame 7. The drive mechanism includes a connecting plate 15 welded to the top of the mounting frame 6 and the top of the connecting frame 7. A rotatable handwheel rod 16 passes through the connecting plate 15, with its bottom end extending into the mounting frame 6. A support shaft 17 is rotatably connected to the top of the connecting plate 15. A transmission assembly is connected to the support shaft 17 and the handwheel rod 16. The bottom of the transmission assembly is connected to the top of the keel frame 11 furthest from the mounting frame 6. The transmission assembly includes two synchronous pulleys 18, which are fixedly mounted on the handwheel lever 16 and the support shaft 17 respectively via key connections. A synchronous belt 19 is mounted on both synchronous pulleys 18. An L-shaped fixing plate 20 is bolted to one side of the synchronous belt 19, and the bottom of the L-shaped fixing plate 20 is welded to the top of the keel frame 11 furthest from the mounting frame 6. When the operator rotates the handwheel lever 16, it drives the connected synchronous pulley 18 to rotate. Under the support and transmission of the other synchronous pulley 18, the synchronous belt 19 moves, which in turn moves the L-shaped fixing plate 20, pulling the corresponding keel frame 11 to move, thus enabling the tarpaulin 12 to unfold or retract.

[0030] This application can be used in the field of awning technology, or in other fields applicable to this application.

[0031] Example 3: Reference Figure 1-2 Based on Embodiment 1, an improvement is made to a food truck body with a rain canopy, which is applied to the field of rain canopy technology. A baffle is welded to one side of the L-shaped fixed plate 20, and a guide rail 21 is welded to the top of the mounting frame 6 and the top of the connecting frame 7, so that the baffle is slidably fitted into the guide rail 21. Through the horizontal sliding cooperation of the guide rail 21 and the baffle, the L-shaped fixed plate 20 is horizontally slidably supported, ensuring that the L-shaped fixed plate 20 drives the corresponding keel frame 11 to move stably, so that the tarpaulin 12 unfolds or retracts smoothly.

[0032] The same cover plate 22 is also fixedly installed on the top of the mounting bracket 6 and the top of the connecting bracket 7 by bolts. The cover plate 22 is used to cover the connecting plate 15, the two synchronous pulleys 18, the synchronous belt 19, the L-shaped fixing plate 20 and the guard rail 21. The cover plate 22 can protect the main components such as the connecting plate 15, the two synchronous pulleys 18, the synchronous belt 19, the L-shaped fixing plate 20 and the guard rail 21, and can effectively prevent the synchronous belt 19 and the synchronous pulleys 18 from aging due to wind and sun exposure.

[0033] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
