Description

Technical Field

[0001] This utility model relates to the field of catering vehicle equipment technology, and in particular to an expandable banquet catering vehicle compartment. Background Technology

[0002] Banquet trucks offer a flexible, stylish, and efficient catering service that breaks away from the traditional fixed banquet model, injecting new vitality into various events. Whether it's a wedding, a corporate party, a birthday celebration, or other festivities, banquet trucks provide a unique experience. To increase interior space, they are typically expanded; they unfold to increase usable area when in use and fold up for transport, reducing the overall size of the vehicle.

[0003] Existing expandable banquet trucks typically extend the main body of the truck to increase usable space. However, the expansion trucks rely entirely on the main truck for support, which makes them unstable during use, prone to swaying, affecting the stability of food placement, or requiring manual extension of the legs, increasing the workload for staff and causing inconvenience.

[0004] Therefore, an expandable banquet car has now been developed that can automatically deploy electric support legs when the car is extended, providing stability and reducing the workload of staff. Utility Model Content

[0005] To overcome the shortcomings of existing expandable banquet carts, such as lack of stability during use, easy swaying affecting the stability of food placement, or the need for manual extension of the support legs, which increases the workload of staff and is inconvenient, this utility model provides an expandable banquet cart that can automatically extend electric support legs when the cart is extended, providing stability and reducing the workload of staff.

[0006] The technical implementation scheme of this utility model is as follows: An expandable banquet car includes a car body, an expansion box, a motor, a first gear, a first rack, a second gear, a second rack, a third rack, a connecting rod, a connector, an electric support leg, and a rotating frame. Expansion boxes are slidably connected to both the front and rear sides of the car body. A motor is connected to the bottom of the car body, and a first gear is connected to the motor's output shaft. First racks are connected to each expansion box, and each rack meshes with a first gear. Second gears are rotatably connected to the left and right sides of the expansion box. Two second racks are connected to the left and right sides of the car body, and each rack meshes with an adjacent second gear. Third racks are also slidably connected to both the front and rear sides of the car body, and each rack meshes with an adjacent second gear. Connecting rods are rotatably connected to each third rack. Connecting members are connected to both the left and right sides of the car body, and electric support legs are rotatably connected to each connecting member. Rotating frames are also connected to each connecting member, and each rotating frame is connected to an adjacent electric support leg and a rotatably connected to an adjacent connecting rod.

[0007] Furthermore, each of the electric support legs has a locking slot.

[0008] Furthermore, each of the electric support legs is equipped with a foot pad.

[0009] Furthermore, it also includes guide rods, limiting frames, and telescopic springs. Guide rods are connected to the connectors, and limiting frames are slidably connected between the guide rods on the same expansion box. Each limiting frame is connected to an adjacent guide rod by a telescopic spring, and each limiting frame is engaged with an adjacent electric support leg.

[0010] Furthermore, each restraint frame is equipped with a handle.

[0011] Furthermore, both ends of the restraint frame are semi-circular structures.

[0012] This invention has the following advantages: By sliding and unfolding the expansion box, the second gear moves and the third rack slides, causing the extrusion rotating frame to rotate downwards, which in turn causes the electric support leg to rotate downwards by 90 degrees on the connecting piece for support. This achieves the effect of automatically unfolding the electric support leg when the food cart is expanded, providing stability and reducing the workload of staff. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] An expandable banquet dining car, such as Figures 1-4 As shown, the system includes a carriage 1, an extension box 2, a motor 3, a first gear 4, a first rack 5, a second gear 6, a second rack 7, a third rack 8, a connecting rod 9, a connecting piece 10, an electric support leg 11, and a rotating frame 12. The extension box 2 is slidably connected to both the front and rear sides of the carriage 1. The motor 3 is connected to the bottom of the carriage 1, and the first gear 4 is connected to the output shaft of the motor 3. Each extension box 2 is connected to a first rack 5, which meshes with the first gear 4. The left and right sides of the extension box 2 are rotatably connected to second gears 6. Each left and right side of the carriage 1 is connected to two second racks 7. Each rack 7 meshes with the adjacent second gear 6. The front and rear parts of the carriage 1 are also slidably connected with a third rack 8, which also meshes with the adjacent second gear 6. Each third rack 8 is rotatably connected with a connecting rod 9. Each left and right part of the carriage 1 is connected with a connecting piece 10, and each connecting piece 10 is rotatably connected with an electric support leg 11. Each connecting piece 10 is also connected with a rotating frame 12, which is connected to the adjacent electric support leg 11. Each rotating frame 12 is rotatably connected to the adjacent connecting rod 9. Each electric support leg 11 has a slot and a foot pad.

[0021] like Figure 5As shown, it also includes guide rods 13, limiting frames 14 and telescopic springs 15. Guide rods 13 are connected to each connector 10. Limiting frames 14 are slidably connected between the guide rods 13 on the same expansion box 2. Each limiting frame 14 is connected to an adjacent guide rod 13 by a telescopic spring 15. Each limiting frame 14 is snapped into an adjacent electric support leg 11. Each limiting frame 14 is equipped with a handle for easy pulling. Both ends of the limiting frame 14 are semi-circular structures.

[0022] When using this invention, first place the device inside the banquet hall of the dining car. Then, start the motor 3 to rotate the first gear 4. Through the meshing motion of the first gear 4 and the first rack 5, the first rack 5 slides outward, causing the extension box 2 to slide outward, thus expanding the carriage 1. While the extension box 2 slides outward, it drives the second gear 6 to move. Through the meshing motion of the second gear 6 and the second rack 7, the second gear 6 rotates. Through the meshing motion of the second gear 6 and the third rack 8, the third rack 8 slides, causing the connecting rod to rotate between the rotating frame 12 and the third rack 8, squeezing the rotating frame 12 to rotate downward, causing the electric support leg 11 to rotate downward 90 degrees on the connecting piece 10. Then, by starting the electric support leg 11, the electric support leg 11 is pushed out to the ground. The electric support leg 11 supports the expansion box 2 through surface contact. During the rotation of the electric support leg 11, the compression limiting frame 14 slides outward on the guide rod 13, and the telescopic spring 15 is compressed and contracted. When the electric support leg 11 rotates to the vertical position, the limiting frame 14 aligns with the locking groove on the electric support leg 11, the telescopic spring 15 rebounds, and the limiting frame 14 is driven into the electric support leg 11 to fix the electric support leg 11 and enhance its stability. This allows the electric support leg 11 to automatically unfold when the food cart is extended, providing stability and reducing the workload of the staff. When it is necessary to retract the expansion box 2, simply pull the limiting frame 14 outward to retract the electric support leg 11, and then control the motor 3 to rotate in the opposite direction to retract the expansion box 2.
