[0024] 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.

[0025] Please see Figure 1-6This embodiment provides a technical solution: a transfer vehicle for food delivery, including a frame 1, with lockable universal wheels 9 symmetrically arranged on the left and right sides of the lower surface of the frame 1 (the lockable universal wheels 9 can be 45A20-1137 model universal locking shockproof directional casters), and directional casters 10 symmetrically arranged on the left and right sides of the lower surface of the frame 1. It also includes a fixing mechanism 4. When the lockable universal wheels 9 need to be locked, the locking rod is stepped on or pushed, and the brake pads are driven to press the wheel axle through the linkage mechanism to prevent the wheel from rolling.

[0026] The frame 1 has evenly distributed T-slots 2 on its upper surface. T-sliders 3 are slidably connected inside the T-slots 2. A fence 5 is fixedly connected to the upper side of the five T-sliders 3 on the left side, and a fence 5 is also fixedly connected to the upper side of the five T-sliders 3 on the right side. A rear fixing plate 7 is symmetrically fixedly connected to the rear side of the upper surface of the frame 1. A limiting cylinder 8 is evenly distributed fixedly connected to the front side of the rear fixing plate 7. The inner arc surface of the limiting cylinder 8 is slidably connected to the outer arc surface of the steel pipe of the fence 5 on the same side. A rear sealing plate 12 is hinged to the rear side of the lower buckle 47 by a pin. A lock 14 is symmetrically provided on the upper side of the rear side of the rear side of the rear sealing plate 12. The rear side of the rear fixing plate 7 is... Fasteners are provided on the upper middle part of the surface. The locking buckle 14 corresponds to the front and rear positions of the fasteners on the same side. The front side of the board frame 1 is provided with a handle 13. The right front side of the left fence 5 is provided with evenly distributed telescopic rods 6. The telescopic end of the telescopic rod 6 is fixedly connected to the left front side of the right fence 5. When the transfer vehicle is needed, the locking buckle 14 can be manually released so that the locking buckle 14 and the fastener are no longer locked. At this time, the rear sealing plate 12 can be opened, and the food container or food box can be placed on the upper surface of the board frame 1. Then these food containers or food boxes are stacked in sequence. During this period, the spacing between the two sets of fences 5 can be adjusted according to the size of the food container or food box.

[0027] Fixing mechanism 4 includes a fixing base 41, an inner rotating cylinder 42, a connecting frame 44, an outer rotating cylinder 45, and a lower fastener 47. The lower fastener 47 is fixedly connected to the middle of the lower surface of the plate frame 1. The lower surface of the plate frame 1 is fixedly connected with evenly distributed fixing bases 41. An inner rotating cylinder 42 is rotatably connected inside every two horizontally adjacent fixing bases 41. An outer rotating cylinder 45 is provided on the left and right sides of the outer arc surface of the inner rotating cylinder 42. The upper side of the outer rotating cylinder 45 is fixedly connected to the lower end of the vertically adjacent T-shaped slider 3 through the connecting frame 44. The middle part of the outer arc surface of the inner rotating cylinder 42 is rotatably connected to the left and right walls of a lower fastener 47, respectively. The fixing mechanism 4 also includes threaded holes 43 and screws 46. The threaded holes 43 are respectively opened in the inner rotating cylinder 42. The middle of the left side and the middle of the right side of the inner cylinder 42, the middle of the left wall of the outer cylinder 45 on the left side, and the middle of the right wall of the outer cylinder 45 on the right side are respectively fixedly connected to screws 46. The external thread surface of the screws 46 is respectively connected to the internal thread of the threaded hole 43 located at the same position. The inner cylinder 42 and the outer cylinder 45 are sleeved, which effectively prevents the external thread surface of the screws 46 from being contaminated and affecting the transmission efficiency. The screws 46 on the left side and the screws 46 on the right side have opposite thread directions. The fixing mechanism 4 also includes worm gears 48 and worms 49. Worms 48 are respectively fixedly sleeved on the middle of the outer arc surface of the inner cylinder 42. Worms 49 are respectively provided on the upper side of the worm gears 48. Every two longitudinally adjacent worms 49 are fixedly connected. The front end of the foremost worm 49 is connected to the lower fastener. The front wall of the bracket 47 is fixedly connected. The worm gear 48 and worm 49 are both located inside the lower bracket 47 to prevent external dirt from contaminating the transmission of the worm gear 48 and worm 49. The rear end of the worm 49 is fixedly connected to the rear wall of the lower bracket 47. The worm 49 is respectively engaged with the worm gear 48 in the longitudinal position. The bracket also includes a handle 11, which is fixedly connected to the front end of the foremost worm 49. At this time, the handle 11 needs to be manually turned to drive the five worms 49 to rotate synchronously in the forward and reverse directions, thereby driving the worm gear 48 to rotate, and then driving the five inner rotating cylinders 42 to rotate synchronously in the forward and reverse directions. Due to the threaded connection between the threaded hole 43 and the screw 46, when the inner rotating cylinders 42 rotate in the forward and reverse directions, the five T-shaped sliders on the left side... 3. The five T-shaped sliders 3 on the right move relatively away from or relatively close to each other, thereby causing the left fence 5 and the right fence 5 to move relatively away from or relatively close to each other, thus adjusting the distance between the two sets of fences 5. During the adjustment, the telescopic rod 6 can adaptively extend and retract, ensuring that the telescopic rod 6 on the front side of the fence 5 can limit the front position and prevent items from falling from the front. The limiting cylinder 8 slides and connects with the outer arc surface of the steel pipe of the fence 5, which can prevent items from falling from the rear. After the food container or food box is placed, the rear sealing plate 12 is closed and the latch 14 is locked. The distance between the two sets of fences 5 can be reduced by the above method, so that the fence 5 restricts the food container or food box. At this time, the plate frame 1 can be pushed by the handle 13.The transfer vehicle can be moved freely using the lockable swivel casters 9 and directional casters 10, allowing food containers or boxes to be moved to designated locations to complete food delivery.

[0028] The working principle of the food delivery transfer vehicle provided by this utility model is as follows: When the transfer vehicle is needed, the lock 14 can be manually released, so that the lock 14 and the fastener are no longer locked. At this time, the rear sealing plate 12 can be opened, and the food container or food box can be placed on the upper surface of the rack 1. Then, these food containers or food boxes are stacked in sequence. During this process, the spacing between the two sets of fences 5 is adjusted according to the size of the food containers or food boxes. At this time, the handle 11 needs to be manually turned to drive the five worm gears 49 to rotate synchronously in the forward and reverse directions, which in turn drives the worm wheel 48 to rotate, which in turn drives the five inner rotating cylinders 42 to rotate synchronously in the forward and reverse directions. Due to the threaded connection between the threaded hole 43 and the screw 46, when the inner rotating cylinders 42 rotate in the forward and reverse directions, the five T-shaped sliders 3 on the left and the five T-shaped sliders 3 on the right move together. The relative movement of the left and right fences 5 causes the left and right fences 5 to move relatively away or closer, thereby adjusting the distance between the two sets of fences 5. During the adjustment, the telescopic rod 6 can adaptively extend and retract, ensuring that the telescopic rod 6 on the front side of the fence 5 can limit the front position and prevent items from falling from the front. The limiting cylinder 8 is slidably connected to the outer arc surface of the steel pipe of the fence 5, which can prevent items from falling from the rear. After the food container or food box is placed, the rear sealing plate 12 is closed and the latch 14 is locked. The distance between the two sets of fences 5 can be reduced by the above method, so that the fence 5 restricts the food container or food box. At this time, the plate frame 1 can be pushed by the handle 13, and the transfer vehicle can be moved at will by the lockable universal wheels 9 and the directional casters 10 to move the food container or food box to the designated position and complete the food delivery.
