[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0018] See also Figure 1-5 The utility model provides a technical solution: a cold chain food delivery box with a protective structure, including a delivery box body 1, a cover plate 2 is installed on the upper end of the delivery box body 1 by bolts, a limiting mechanism 3 is arranged inside the delivery box body 1, and a pressing mechanism 4 is connected to the surface of the cover plate 2, and the pressing mechanism 4 passes through the cover plate 2. The limiting mechanism 3 includes a mounting plate 31, the mounting plate 31 is connected inside the delivery box body 1, a friction plate 32 is fixedly connected to the upper end of the mounting plate 31, a limiting frame 33 is arranged inside the delivery box body 1, a plurality of H-shaped sliders 34 are slidably connected inside the limiting frame 33, and a moving rod 35 is slidably connected to the surface of the plurality of H-shaped sliders 34, and the moving rod 35 passes through the H-shaped slider 34, and an elastic friction component 37 is connected to the lower end of the moving rod 35, and the elastic friction component 37 is arranged corresponding to the friction plate 32, A first spring 36 is wound around the surface of the moving rod 35, one end of the first spring 36 is connected to the H-shaped slider 34, the other end of the first spring 36 is connected to the elastic friction component 37, one end of the H-shaped slider 34 is fixedly connected to the limit plate 38, and a limit rod 39 is arranged inside the delivery box body 1, the limit rod 39 passes through the limit plate 38 and is slidably connected to the limit plate 38, and a pressing mechanism 4 is connected to the surface of the cover plate 2, the pressing mechanism 4 passes through the cover plate 2, and the lower end of the pressing mechanism 4 corresponds to the upper end of the moving rod 35.

[0019] In the present embodiment, the food to be transported is first placed inside the delivery box body 1, and then the limiting plate 38 is moved so that the limiting plate 38 slides on the surface of the limiting rod 39. At the same time, due to the movement of the limiting plate 38, the H-shaped slider 34 is driven to slide inside the limiting frame 33, thereby driving the moving rod 35 and the elastic friction component 37 to move. When the limiting plate 38 moves to a suitable position, the food to be transported can be limited by two limiting plates 38 or one limiting plate 38 and the side wall of the delivery box body 1, and then the cover plate 2 is installed on the upper end of the delivery box body 1. When the cover plate 2 is close to the upper end of the delivery box body 1, the pressing mechanism 4 squeezes the moving rod 35, so that the moving rod 35 slides downward inside the H-shaped slider 34. At this time, the first spring 36 When the cover 2 is stretched, the moving rod 35 slides downward, thereby driving the elastic friction component 37 to move downward. When the cover 2 is installed, the elastic friction component 37 squeezes the friction plate 32. Through the deformation of the elastic friction component 37, a large friction force can be generated with the friction plate 32, thereby completing the self-locking of the limit plate 38, and then completing the fixation of the limit plate 38, so as to effectively limit the protection of the food to be transported. When the transportation is completed, the cover 2 is disassembled, so that the pressing mechanism 4 is separated from the moving rod 35. Under the action of the elastic force of the first spring 36, the elastic friction component 37 is separated from the friction plate 32 to complete the unlocking of this mechanism. Therefore, by setting the limit mechanism 3, the food to be transported can be limited by moving the limit plate 38, thereby protecting the food during transportation.

[0020] Specifically, the elastic friction assembly 37 includes a connecting block 371, the lower end of the movable rod 35 is connected to the connecting block 371, the surface of the connecting block 371 is slidably connected to a plurality of sliding rods 372, the plurality of sliding rods 372 all penetrate the connecting block 371, the lower end of the sliding rod 372 is fixedly connected to a fixed block 373, the surface of the sliding rod 372 is wrapped with a second spring 374, the upper end of the second spring 374 is connected to the connecting block 371, the lower end of the second spring 374 is connected to the fixed block 373, and the lower end of the fixed block 373 is fixedly connected to a friction block 375.

[0021] In this embodiment, when the elastic friction component 37 squeezes the friction plate 32, the friction block 375 first contacts the friction plate 32, and several sliding rods 372 slide upward. At the same time, the second spring 374 is compressed. Under the elastic force of the second spring 374, the friction block 375 is in close contact with the friction plate 32, thereby generating friction force, and then the limit plate 38 is frictionally self-locked.

[0022] Specifically, anti-slip rubber pads are provided on both sides of the limiting plate 38 .

[0023] In this embodiment, since the anti-skid rubber pad has anti-skid properties and elasticity, it not only improves the limiting effect on the food, but also can provide buffering protection for the food during transportation.

[0024] Specifically, the pressing mechanism 4 includes a lifting rod 41. Two symmetrically arranged lifting rods 41 are slidably connected to the surface of the cover plate 2. The two lifting rods 41 both penetrate the cover plate 2. The lower ends of the lifting rods 41 are fixedly connected to a pressing plate 43. A groove 46 is provided at the lower end of the pressing plate 43. The upper ends of the lifting rods 41 are fixedly connected to a connecting plate 42. A threaded rod 44 is threadedly connected to the surface of the cover plate 2. The threaded rod 44 penetrates the cover plate 2. The upper ends of the threaded rods 44 are rotatably connected to the connecting plate 42 through a ball bearing. The lower ends of the threaded rods 44 are rotatably connected to the pressing plate 43. The pressing plate 43 is correspondingly arranged to the moving rod 35.

[0025] In this embodiment, the threaded rod 44 is first rotated to make the threaded rod 44 rise and fall, and then the two lifting rods 41 are driven to rise and fall through the connecting plate 42, and then the pressing plate 43 is driven to move. Since the pressing plate 43 moves, the distance between the pressing plate 43 and the cover plate 2 can be adjusted. When the cover plate 2 is close to the upper end of the delivery box body 1, the pressing plate 43 presses the moving rod 35 through the groove 46. Since this mechanism can adjust the distance between the pressing plate 43 and the cover plate 2, this mechanism can adjust the pressing distance of the pressing plate 43 on the moving rod 35, so that the squeezing force of the elastic friction component 37 on the friction plate 32 can be adjusted, and then the limiting effect on the limiting plate 38 can be adjusted, and then the limiting effect on the food can be adjusted to meet the limiting requirements of different weights of food during transportation.

[0026] Specifically, a rotating block 45 is fixedly connected to the surface of the threaded rod 44 .

[0027] In this embodiment, the threaded rod 44 can be rotated by rotating the rotating block 45 , so that the user can operate the pressing mechanism 4 more conveniently.

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
