Description
Technical Field
[0001] This utility model relates to the field of catering equipment technology, specifically a fast food cart with multiple food pick-up ports. Background Technology
[0002] Food carts are flexible mobile food service units, commonly found in high-traffic areas such as streets and squares, emphasizing convenient service. They typically have multiple service windows for quick ordering and pickup. Each window is equipped with an openable door; when not in use, the window can be closed to prevent dust from entering and ensure food hygiene. When the door is rotated upwards, it forms a sunshade or rain shelter, protecting the window area from sunlight and rain, enhancing the customer experience and providing a comfortable working environment for staff – practical and thoughtful. Each service window of the food truck has an independently designed door panel. Staff members need to manually rotate and fix multiple door panels one by one to provide shade and protection from rain. For example, if there are door panels on three sides, staff members need to lift and support one door panel, and then walk to the other side to do the same. This independent operation needs to be repeated many times, which is cumbersome and inconvenient. Utility Model Content
[0003] The purpose of this invention is to provide a food cart with multiple food pick-up ports to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a food cart with multiple food pick-up slots, comprising a vehicle body with multiple windows and first door panels disposed on both sides of the vehicle body, the first door panels being rotatably connected to the vehicle body, and further comprising: The second door panel is located on the other side of the vehicle body and is smaller in area than the first door panel. A connecting rod is bolted to one side of the second door panel. The transmission mechanism is located on one side above the vehicle body. The transmission mechanism consists of a transmission rod and a second gear set. The transmission rod is fixed to the surface of the vehicle body by bearings. There are two sets of the second gear set, and each set consists of two meshing bevel gears. The second gear set serves as a bridge for transmitting power between the first door panels on both sides. The other end of the connecting rod is welded to the transmission rod. The cover is bolted to the top of the vehicle body, and the transmission rod and the second gear set are both located inside the cover; A threaded push-pull mechanism is located on one side of the vehicle body. The threaded push-pull mechanism is used to control the raising or lowering of one of the first door panels.
[0005] Preferably, the threaded push-pull mechanism includes: A vertical cylinder is bolted to the inside of the vehicle body; The movable block is slidably connected to the inner wall of the vertical cylinder, and one end of the movable block extends to the outside of the vertical cylinder; A vertical groove is formed on the surface of the vertical cylinder and is used to provide a range for vertical movement to the extension of the movable block; The screw is rotatably connected to the inside of the vertical cylinder; A threaded sleeve is provided through the surface of the movable block and threadedly connected to the surface of the screw, and cooperates with the screw to control the vertical height of the movable block; The hand-cranked assembly is connected to the screw via gear transmission; The push-pull rod has one end hinged to the extension of the movable block; A connector is welded to one of the first door panels, and the end of the push-pull rod away from the movable block is hinged to the connector. A one-way positioning component prevents the screw from rotating in the opposite direction due to gravity.
[0006] Preferably, the hand crank assembly consists of a hand crank handle and a first gear set, wherein the hand crank handle is rotatably connected to the vertical cylinder, and the hand crank handle is rotatably connected to the screw through the first gear set.
[0007] Preferably, the first gear set consists of two meshing spur gears of different sizes. The smaller spur gear in the first gear set is fixed to the surface of the hand crank, and the larger spur gear in the first gear set is fixed to the surface of the screw.
[0008] Preferably, the unidirectional positioning component includes: A ratchet is bolted to the surface of the screw; A box body, which is disposed through the surface of the vertical cylinder; The vertical rod is rotatably connected to the inner wall of the box. A pawl is attached to the bottom end of the vertical rod. An elastic element provides a force to the vertical rod, causing the pawl and the ratchet to come into contact.
[0009] Preferably, a lever is also fixed to one side of the vertical rod.
[0010] Preferably, the elastic element is a torsion spring, and one end of the torsion spring is fixed to the inner wall of the box, while the other end of the torsion spring is in contact with the lever. The force of the torsion spring is applied to the surface of the vertical rod through the lever.
[0011] Preferably, there are two sets of the second gear set. The second gear set consists of two meshing bevel gears of the same size. The two bevel gears in the second gear set are respectively fixed to the end of the transmission rod and the end of the first door panel shaft.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When the first door panel is raised or lowered, the rotation of its shaft drives the rotation of the second gear set. The transmission rod drives the second door panel to be raised synchronously through the connecting rod. At the same time, the second gear set on the other side transmits power to the shaft of the first door panel on that side, realizing the synchronous movement of the first and second door panels on all three sides. This eliminates the need for staff to walk back and forth to operate them one by one, improving convenience.
[0013] 2. This utility model achieves initial labor saving by rotating the hand crank of the hand crank assembly, which in turn drives the screw to rotate. The threaded sleeve on the surface of the screw is threadedly connected to the movable block. When the screw rotates, it pushes the movable block up and down along the vertical groove through the threaded sleeve. The movable block drives the first door panel to rise through the push-pull rod and the connecting piece. By utilizing the principle of the inclined surface of the screw thread, a second labor saving is achieved, reducing the intensity of operation.
[0014] 3. When the screw of this utility model rotates, the ratchet on its surface rotates synchronously. The elastic element pushes the vertical rod and the pawl to fit against the ratchet surface through the lever, preventing the screw from rotating in the opposite direction due to the gravity of the first door panel and the second door panel, ensuring that the door panel is stably suspended. When retracting, pressing the lever drives the vertical rod to rotate, causing the pawl to disengage from the ratchet, allowing the screw to reverse. The movable block descends and drives the door panel to retract through the push-pull rod. The operation is convenient and reliable. Attached Figure Description

Detailed Implementation
[0017] 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.
[0018] Please see Figures 1-8 As shown, a food cart with multiple serving ports includes a cart body 100 and a first door panel 200. The cart body 100 has multiple windows. Two sets of first door panels 200 are respectively located on both sides of the cart body 100 and are rotatably connected to the cart body 100. The cart also includes a second door panel 300, a transmission mechanism 600, a cover 400, and a threaded push-pull mechanism 500. The second door panel 300 is located on the other side of the cart body 100, and its area is smaller than that of the first door panel 200. A connecting rod 310 is bolted to one side of the second door panel 300. The transmission mechanism 600 is located above the cart body 100. On one side, the transmission mechanism 600 consists of a transmission rod 610 and a second gear set 620. The transmission rod 610 is fixed to the surface of the vehicle body 100 by bearings. There are two sets of second gear sets 620, each consisting of two meshing bevel gears. These sets serve as a bridge for transmitting power between the first door panels 200 on both sides. The other end of the connecting rod 310 is welded to the transmission rod 610. Under the action of the connecting rod 310, the second door panel 300 and the transmission rod 610 are fixed to each other. The cover 400 is bolted to the top of the vehicle body 100, and both the transmission rod 610 and the second gear set 620 are located inside the cover 400.
[0019] A threaded push-pull mechanism 500 is disposed on one side inside the vehicle body 100. The threaded push-pull mechanism 500 is used to control the lifting or lowering of one set of first door panels 200. Specifically, the threaded push-pull mechanism 500 includes a vertical cylinder 510, a movable block 530, a vertical groove 520, a screw 540, a threaded sleeve 560, a hand crank assembly 550, a push-pull rod 570, and a connector 580. The vertical cylinder 510 is bolted to the inside of the vehicle body 100. The movable block 530 is slidably connected to the inner wall of the vertical cylinder 510, with one end of the movable block 530 extending to the outside of the vertical cylinder 510. The vertical groove 520 is formed on the surface of the vertical cylinder 510 and provides a range for vertical movement to the extended portion of the movable block 530. The screw 540... The screw rod 540 is rotatably connected to the inside of the vertical cylinder 510. The threaded sleeve 560 passes through the surface of the movable block 530 and is threadedly connected to the surface of the screw rod 540. It works with the screw rod 540 to control the vertical height of the movable block 530. During the rotation of the screw rod 540, it can drive the movable block 530 to move up and down through the threaded sleeve 560. The hand crank assembly 550 is connected to the screw rod 540 through gear transmission. The push-pull rod 570 has one end hinged to the extension of the movable block 530. The connecting piece 580 is welded to one of the first door panels 200. The end of the push-pull rod 570 away from the movable block 530 is hinged to the connecting piece 580. The one-way positioning assembly 590 prevents the screw rod 540 from rotating in the opposite direction under the action of gravity.
[0020] Furthermore, the hand crank assembly 550 consists of a hand crank 551 and a first gear set 552. The hand crank 551 is rotatably connected to the vertical cylinder 510, and the hand crank 551 is rotatably connected to the screw 540 through the first gear set 552.
[0021] Furthermore, the first gear set 552 consists of two meshing spur gears of different sizes. The smaller spur gear in the first gear set 552 is fixed to the surface of the hand crank 551, and the larger spur gear in the first gear set 552 is fixed to the surface of the screw 540. Through the hand crank 551 and the first gear set 552, the screw 540 can be rotated. Moreover, the smaller gear drives the larger gear, achieving a labor-saving effect.
[0022] Furthermore, the one-way positioning assembly 590 includes a ratchet 591, a housing 592, a vertical rod 593, a pawl 594, and an elastic element 595. The ratchet 591 is bolted to the surface of the screw 540. The housing 592 is disposed through the surface of the vertical cylinder 510. The vertical rod 593 is rotatably connected to the inner wall of the housing 592. The pawl 594 is bolted to the bottom end of the vertical rod 593. The elastic element 595 provides a force to the vertical rod 593 to make the pawl 594 contact the ratchet 591. A lever 596 is also fixed on one side of the vertical rod 593.
[0023] Furthermore, the elastic element 595 is a torsion spring, and one end of the torsion spring is fixed to the inner wall of the box 592. The other end of the torsion spring is in contact with the lever 596. The force of the torsion spring is applied to the surface of the vertical rod 593 through the lever 596. The vertical rod 593 drives the pawl 594 to fit against the surface of the ratchet 591. There are two sets of second gear sets 620. The second gear set 620 consists of two meshing bevel gears of the same size. The two bevel gears in the second gear set 620 are respectively fixed to the end of the transmission rod 610 and the end of the first door panel 200 shaft.
[0024] Working principle: When opening the three reverse door panels for business operations, the hand crank 551 is first turned. The hand crank 551 drives the large gear in the first gear set 552 through the small gear, which in turn drives the screw 540 to rotate, achieving an initial labor-saving effect. The threaded sleeve 560 on the surface of the screw 540 rises, driving the movable block 530 to rise as well. The thread of the screw 540 is a wound inclined plane. When rotating, the small force applied over a long distance is converted into a strong thrust that pushes the threaded sleeve 560, but the pushing distance is very short. According to the principle of work, it saves effort but increases the distance, achieving a secondary labor-saving effect. Moreover, the clockwise rotation of the screw 540 drives the ratchet 591. The ratchet 591 rotates clockwise, and the pawl 594 allows the ratchet 591 to rotate clockwise. At this time, the movable block 530 drives the push-pull rod 570 to rise at the end closest to itself, and uses the connecting piece 580 to push the first door panel 200 on that side to rotate, so that the first door panel 200 on that side is raised, thereby driving the shaft of the first door panel 200 to rotate, and through the second gear set 620, driving the transmission rod 610 to rotate. The transmission rod 610 drives the second door panel 300 to rise through the connecting rod 310, and through the second gear set 620 on the other side, drives the first door panel 200 on the other side to rise. In this way, the door panels in three directions are raised at the same time, which is more convenient and does not require multiple back-and-forth operations.
[0025] Furthermore, during the lifting of the first door panel 200, the cooperation between the pawl 594 and the ratchet 591 prevents the screw 540 from rotating counterclockwise, and prevents the combined weight of the first door panel 200 and the second door panel 300 from being applied to the screw 540 for lifting due to the transmission effect, thus preventing the screw 540 from easily rotating in the opposite direction. In the design process, the first door panel 200 and the second door panel 300 are made of relatively lightweight materials to save labor for the staff, such as aluminum alloy.
[0026] After business hours, to facilitate the retrieval of the first door panel 200 and the second door panel 300, the staff can use one hand to turn the hand crank 551 to rotate the screw 540 counterclockwise, and the other hand to press the lever 596 to disengage the pawl 594 from the surface of the ratchet 591, allowing the screw 540 to rotate counterclockwise for retrieval. Then, the movable block 530 descends, and the push-pull rod 570 drives the first door panel 200 to descend, and simultaneously drives the other first door panel 200 and the second door panel 300 to descend through the second gear set 620 and the transmission rod 610, completing the retrieval.
[0027] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
