Description

Technical Field

[0001] This utility model relates to the field of catering delivery equipment, and in particular to a stair-climbing machine catering support frame. Background Technology

[0002] With the development of the food delivery industry, stair-climbing machines are being used more and more widely in last-mile food delivery and other scenarios. Especially in older residential areas without elevators, using stair-climbing machines to deliver meals can significantly reduce labor costs and labor intensity.

[0003] In the food delivery industry, existing stair-climbing machines typically use a base support structure at their bottom to place the food containers. When food delivery is needed, the operator first extends the base support of the stair-climbing machine backward to create a horizontal bearing surface, and then places the food container directly on the base support. Because the stair-climbing machine needs to move at an angle along the stairs, the delivery personnel need to tilt the equipment at a certain angle in the direction of travel (usually an angle of 30°-60° with the horizontal plane), and pull the handle to drive the tracked or wheeled structure to move upstairs.

[0004] The inventors discovered that the aforementioned prior art has at least the following drawbacks: because the stair climber needs to maintain an inclined state during operation, while the food container is placed directly on the horizontal support, a large inclined surface is formed between the food container and the horizontal plane during the stair climber's ascent, which easily leads to the food inside the container spilling or overflowing. Utility Model Content

[0005] This application provides a meal delivery rack for a stair climber, which solves the technical problem in the prior art where food in the meal box is prone to spillage or overflow when the stair climber is tilted.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a stair-climbing machine meal delivery support frame, including a support structure for placing meal boxes. The support structure includes a fixed frame, and locking components are provided on both sides of the fixed frame. The locking components can be fixed to the sides of the stair-climbing machine frame. A tray and a support rod are fixed on the upper surface of the fixed frame. The support rod is supported below the tray. The angle formed between the plane of the tray and the plane of the fixed frame is greater than 30° and less than 60°. Because the plane of the tray and the plane of the fixed frame form a certain angle, when the stair-climbing machine moves at an incline along the stairs, this angle can effectively counteract the tilt angle of the stair-climbing machine, keeping the meal boxes placed on the tray as horizontal as possible or close to horizontal. This significantly reduces the risk of food spilling or overflowing due to tilting, and improves the stability during the meal delivery process.

[0007] As a further improvement to the above solution, the locking component includes a buckle seat and a hook that can be welded and fixed to the frame of the stair climber. A handle is rotatably mounted on the buckle seat, and a rotating shaft is rotatably mounted on the handle. A movable shaft passes through the interior of the rotating shaft in the radial direction along the shaft, and a buckle ring is connected to one end of the movable shaft. When the handle rotates around the buckle seat, the buckle ring can engage inside the hook. Thus, by means of the structure in which the handle rotates around the buckle seat, the buckle ring and the hook can be quickly engaged or disengaged, and the installation or disassembly of the support frame and the stair climber frame can be completed without the aid of tools, improving the convenience of operation.

[0008] As a further improvement to the above solution, the movable shaft is provided with an external thread on its exterior, and correspondingly, the hole on the rotating shaft for installing the movable shaft is provided with an internal thread. The internal thread engages with the external thread on the exterior of the movable shaft. Thus, the movable shaft can be rotated to adjust its extension length within the rotating shaft according to the actual installation gap between the stair climber frame and the support frame, thereby adjusting the relative position of the buckle in the locking component, ensuring that the buckle and the hook fit tightly, and thus avoiding the problem of loose connection.

[0009] As a further improvement to the above solution, at least two trays are provided, and each tray is supported by a support rod underneath; this allows the load-bearing structure to support multiple meal boxes simultaneously, improving meal preparation efficiency.

[0010] As a further improvement to the above solution, the support structure also includes a support frame, one side of which is fixed to a fixed frame, the other side of which is fixed to the upper end of the support rod, and the lower end of the support rod is fixed to the fixed frame; the tray is fixed above the support frame; the support frame can avoid deformation caused by single-point force on the tray, ensuring the stability of the food container.

[0011] As a further improvement to the above solution, both sides of the upper surface of the pallet are provided with guards; the guards can limit the food containers placed on the pallet, thereby preventing the food containers from swaying left and right or even slipping off the side due to vibration or tilting during the movement of the stair climber.

[0012] As a further improvement to the above solution, the length direction of the support rod is perpendicular to the plane of the fixed frame.

[0013] As a further improvement to the above solution, both the fixed frame and the support frame are frame structures formed by welding square tubes.

[0014] As can be seen from the above technical solutions, this utility model has at least the following technical effects or advantages:

[0015] Because the plane of the pallet forms a certain angle with the plane of the fixed frame, the food containers placed on the pallet can maintain a near-horizontal posture as the stair climber ascends the stairs at an incline. This prevents food from spilling or overflowing due to the stair climber's tilt, solving the problem of food spillage caused by the stair climber's tilt in existing technologies. Simultaneously, the support frame is connected to the stair climber frame via locking components, making installation and disassembly convenient. It allows for quick fixing or disassembly without complex operations, improving the efficiency of meal preparation. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0025] This utility model discloses a stair climber meal delivery support frame, which includes a support structure for placing meal boxes. The support structure includes a fixed frame 1, and locking members 2 are provided on both sides of the fixed frame 1. The locking members 2 can be fixed to both sides of the frame 6 of the stair climber. A tray 3 and a support rod 4 are fixed on the upper surface of the fixed frame 1. The support rod 4 is supported below the tray 3. The angle formed between the plane where the tray 3 is located and the plane where the fixed frame 1 is located is greater than 30° and less than 60°.

[0026] like Figure 1 , Figure 2 As shown, the fixing frame 1 is a rectangular frame structure formed by welding square tubing. The length of the fixing frame 1 is close to the length of the stair climber frame 6, and the width of the fixing frame 1 is the same as the width of the stair climber frame 6. The locking components 2 are located symmetrically on both sides of the fixing frame 1. When the fixing frame 1 is placed on the stair climber frame 6, the locking components 2 on both sides of the fixing frame 1 can achieve relative fixation between the fixing frame 1 and the frame 6.

[0027] The tray 3 is a rectangular plate and is fixedly mounted above the fixing frame 1, as shown in the following figure. Figure 2 As shown, one side of the tray 3 is connected to the fixed frame 1 via a support rod 4. The upper end of the support rod 4 rests on the bottom edge of the tray 3, and the lower end of the support plate 4 is welded and fixed to the fixed frame 1, thereby forming an angle α between the plane of the tray 3 and the plane of the fixed frame 1. In this embodiment, α is 45°. When the stair climber moves upwards at an incline along the stairs, the incline angle of the tray 3 can counteract the incline angle of the stair climber, ensuring that the food container is placed on the tray 3 as horizontally as possible, thus reducing the risk of food spillage.

[0028] Two trays 3 are provided, arranged parallel to each other above the fixed frame 1. Each tray 3 is connected to the fixed frame 1 by two support rods 4. It should be understood that the number of trays 3 can also be three or more. In this embodiment, by setting multiple trays 3, the supporting structure can simultaneously support multiple meal boxes, improving meal preparation efficiency. In addition, each tray 3 is independently supported by support rods 4, thereby flexibly adjusting its placement position according to the size of the meal box, enhancing the applicability of the device.

[0029] In addition, both sides of the upper surface of the tray 3 are provided with guard edges 301. The guard edges 301 are strip-shaped structures fixed to the two opposite edges of the tray 3. The guard edges 301 can position the food container, thereby preventing the food container from slipping off the side of the tray 3 due to left and right swaying during movement, and at the same time, it can facilitate the quick placement and retrieval of the food container.

[0030] In actual operation, such as Figure 3 As shown, the fixing frame 1 is installed on the frame 6 of the stair climber by the locking piece 2, and the food box is placed on the tray 3. Since there is a certain angle α between the plane where the tray 3 is located and the plane where the fixing frame 1 is located, and α is close to the inclination angle of the stair, the food box can be basically kept horizontal.

[0031] In the above structure, by setting a support plate 3 that forms a specific angle with the fixed frame 1, the angle of the stair climber when it travels at an incline is effectively offset, keeping the food container at or near level. This solves the problem of food spillage in existing technologies and improves the safety of meal preparation. At the same time, the support frame is fixed to the stair climber frame 6 by locking components 2, making installation and disassembly more convenient and improving work efficiency.

[0032] In the specific structure of the locking component 2, the locking component 2 includes a buckle seat 201 and a hook 202 that can be welded and fixed to the frame 6 of the stair climber. A handle 203 is rotatably mounted on the buckle seat 201, and a rotating shaft 204 is rotatably mounted on the handle 203. A movable shaft 205 passes through the interior of the rotating shaft 204 in the radial direction. One end of the movable shaft 205 is connected to a buckle ring 206. When the handle 203 rotates around the buckle seat 201, the buckle ring 206 can be engaged inside the hook 202.

[0033] Specifically, such as Figure 4 , Figure 5 As shown, the buckle 201 includes a plate-shaped main body and two flanges. The plate-shaped main body is welded and fixed to the fixed frame 1, and the two flanges are located on both sides of the plate-shaped main body. Each of the two flanges is provided with a pin, which is rotatably connected to one end of the handle 203. The handle 203 has a "U"-shaped structure, and the rotating shaft 204 is rotatably installed near the middle of the handle 203. Therefore, when the handle 203 is rotated, the movable shaft 205 and the buckle ring can be pulled relative to each other, causing the handle 203 to rotate. When the load-bearing structure needs to be installed, align the buckle 201 with the hook 202, rotate the handle 203 away from the fixed frame 1 to make the buckle ring 206 engage in the groove of the hook 202, and then rotate the handle 203 towards the fixed frame 1 to quickly fix the load-bearing frame to the stair climber. For disassembly, rotate the handle 203 away from the fixed frame 1 to disengage the buckle ring 206 from the hook 202.

[0034] In the above structure, the locking component 2 uses a buckle 206 and a hook 202 to cooperate. By rotating the handle 203 to drive the buckle 206 to rotate, the load-bearing structure can be quickly disassembled and assembled. The operation is simple and convenient, and installation and disassembly can be completed without tools, which improves work efficiency.

[0035] More specifically, the movable shaft 205 has an external thread, and correspondingly, the hole on the rotating shaft 204 for mounting the movable shaft 205 has an internal thread, which mates with the external thread on the movable shaft 205. The movable shaft 205 and the rotating shaft 204 are connected by threads. By rotating the movable shaft 205, its extension length on the locking member 2, i.e., the relative position of the retaining ring 206 within the locking member 2, can be adjusted. This helps ensure a tight fit between the retaining ring 206 and the hook 202, enhancing the robustness of the connection between the load-bearing structure and the frame 6.

[0036] On the other hand, such as Figure 6 As shown, the support structure also includes a support frame 5, which is a drive frame structure formed by welding square tubes. One side of the support frame 5 is fixedly connected to the fixed frame 1, and the other side of the support frame 5 is fixed to the upper end of the support rod 4. The lower end of the support rod 4 is fixed to the fixed frame 1, thus forming a triangular support structure. The support frame 5 is a frame structure, and the end of the support frame 5 connected to the fixed frame 1 is fixed by welding to ensure connection strength; the upper and lower ends of the support rod 4 are welded and fixed to the support frame 5 and the fixed frame 1, respectively.

[0037] The tray 3 is fixedly installed above the support frame 5. When the food container is placed on the tray 3, the weight can be distributed to multiple support rods 4 through the frame structure of the support frame 5, and then the support rods 4 transmit the force to the entire frame of the fixed frame 1, rather than concentrating it in a localized area. Therefore, the support frame 5 avoids deformation caused by single-point stress on the tray 3, which helps extend the service life of both the tray 3 and the fixed frame 1, while ensuring the stability of the food container.

[0038] Specifically, the support rod 4 is a square tube, and its length direction is perpendicular to the plane where the fixed frame 1 is located. When the load-bearing structure is installed on the frame 6 of the stair climber via the locking device 2, the two support rods 4 at one end can contact the upper surface of the bottom support 7 of the stair climber, thus forming a more stable support structure. At the same time, this structure simplifies the installation process of the load-bearing structure. During installation, it is only necessary to keep the fixed frame 1 of the load-bearing structure in contact with the frame 6 of the stair climber, and then make the two support rods 4 at one end of the load-bearing structure contact the bottom support 7 to complete the positioning of the load-bearing structure relative to the frame 6, without the need for additional calibration steps.

[0039] The usage process of this utility model is as follows: First, place the support frame 5 on the frame 6 of the stair climber, align the buckle 201 with the hook 202 welded to the frame 6, and rotate the handle 203 to make the buckle 206 engage in the groove of the hook 202. Then, place the meal box on the tray 3. Since the plane of the tray 3 forms a certain angle with the plane of the fixed frame 1, the meal box placed on the tray 3 can maintain a nearly horizontal posture as the stair climber tilts upwards along the stairs, preventing the food in the meal box from spilling or overflowing due to the tilt of the stair climber, thus solving the problem of food spillage caused by the tilt of the stair climber in the prior art. At the same time, the support frame is connected to the stair climber frame through locking parts, making installation and disassembly convenient. Fixing or disassembly can be completed quickly without complicated operations, improving the efficiency of meal preparation.
