Technical Field

[0001] The utility model relates to a transport auxiliary device, in particular to a position limiting and fixing device for vegetable logistics transportation. Background Art

[0002] Vegetables refer to plants or fungi that can be cooked and made into food. They are an essential food in people's daily diet. Vegetables provide a variety of nutrients such as vitamins and minerals that are essential to the human body. 90% of the human body's essential vitamin C and 60% of vitamin A come from vegetables. In addition, vegetables contain a variety of phytochemicals that are recognized as effective ingredients for health. Nutrients in fruits and vegetables are known to be effective in preventing chronic and degenerative diseases, and research is ongoing to discover various substances.

[0003] When vegetables are transported over long distances, they usually need to be packaged in foam boxes or cardboard boxes. The existing transportation method usually directly stacks the boxes in the truck compartment for transportation. As a result, the stacked boxes fall and scatter due to the influence of the truck's braking inertia and the bumpy road surface during transportation, which in turn causes damage to the vegetables and affects their subsequent sales. Therefore, there is an urgent need for a limiting and fixing device for vegetable logistics transportation to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 The utility model provides a technical solution for a limiting and fixing device for vegetable logistics transportation: it includes a placing plate 1, the left and right sides of the placing plate 1 are connected to the mounting mechanism 2, the mounting mechanism 2 is also connected to four sleeve holes 3 at the same time, the four sleeve holes 3 are grouped in twos and the two groups of sleeve holes 3 are respectively opened on the left and right sides of the placing plate 1, and the outer side surface of the placing plate 1 is also connected to the limiting mechanism 4.

[0023] The mounting mechanism 2 includes two threaded barrels 21, both of which are movably connected to the inside of the placement plate 1 through rolling bearings. Each threaded barrel 21 has two sections of threads with opposite spiral directions. The four sections of threads on the two threaded barrels 21 are respectively threadedly connected to one end of the four screws 24.

The other ends of the four slide rods 22 are respectively sleeved in the four sleeve holes 3. By opening the sleeve holes 3 on the placement plate 1 and providing slide rods 22 on the top plate 25 to sleeve into the sleeve holes 3, the movement of the top plate 25 and the screw rods 24 is restricted by the connection between the slide rods 22 and the sleeve holes 3, thereby preventing the screw rods 24 and the top plate 25 from rotating when the threaded cylinder 21 rotates. The right ends of the two threaded cylinders 21 are respectively fixedly connected to the two pulleys 23, and the two pulleys 23 are connected by belt transmission.

[0025] The limiting mechanism 4 includes four fixed plates 41, which are arranged in groups of two and the opposite surfaces of the two groups of fixed plates 41 are fixedly connected to the front and rear side surfaces of the placement plate 1 respectively, and the opposite surfaces of the two rear fixed plates 41 are rotatably connected to the optical axes at both ends of the rear screw 44 through rolling bearings.

The user can control the motor 42 to make the lead screw 44 rotate forward to drive the nuts 43 and the slide rails 414 on both sides to approach each other. When the left and right inner surfaces of the two angle plates 48 are in close contact with the sides of the packaging box respectively, the motor 42 stops working, thereby utilizing the contact between the angle plates 48 and the packaging box to limit the left and right movement of the packaging box.

[0027] The middle optical axes of the two lead screws 44 are fixedly connected to the two bevel gears 2 47 respectively, and the two bevel gears 2 47 are meshed with the two bevel gears 1 46 respectively.

The front and rear lead screws 44 are transmission connected by arranging bevel gear 1 46, bevel gear 2 47 and the connecting shaft 45, so that when the motor 42 drives the front lead screw 44 to rotate, the connecting shaft 45, bevel gear 1 46, and bevel gear 2 47 also drive the rear lead screw 44 to rotate, thereby improving the utilization rate of the power of the motor 42. Two sections of threads with opposite spiral directions are provided on the two lead screws 44. The four sections of threads on the two lead screws 44 are threadedly connected to the four nuts 43 respectively.

The bottom ends of the two limit screws 413 are respectively overlapped with the upper surfaces of the two slide rails 414. By providing a threaded hole 412 on the upper end of the slider 411 and The threaded connection of the limit screw 413 in the hole 412 contacts the slide rail 414, so that the position of the slider 411 is limited by the contact between the limit screw 413 and the slide rail 414, and then the front and rear displacement of the packaging box is limited by the fixed position angle plate 48, the sleeve box 410 and the cross plate 49. The front side of the left angle plate 48 is fixedly connected to the rear sides of multiple sleeve boxes 410 at the same time, and the interiors of the multiple sleeve boxes 410 are respectively connected to the left ends of multiple cross plates 49, and the right ends of the multiple cross plates 49 are fixedly connected to the front side of the right angle plate 48.

When the threaded cylinder 21 rotates in the forward direction, the screw rods 24 and the top plate 25 on the left and right sides move away from each other. When the top plates 25 on both sides are in close contact with the two side facades of the compartment, the threaded cylinder 21 stops rotating.

[0031] When limiting and fixing the transported vegetables, the user can place the vegetable packaging box on the placement plate 1, and after placement is completed, the user can take the angle plate 48, the sleeve 410 and the cross plate 49 to connect the slider 411 with the slide rail 414, and push the angle plate 48 to move backward so that the front inner side of the angle plate 48 contacts the front side of the packaging box. At this time, the user can turn the limit screw 413 so that the limit screw 413 is in close contact with the slide rail 414 to fix the position of the slider 411, the angle plate 48, the sleeve 410 and the cross plate 49. Then the user can control the motor 42 to work so that the screw 44 rotates forward to drive the nuts 43 and the slide rails 414 on both sides to approach each other. When the left and right inner sides of the two angle plates 48 are in close contact with the sides of the packaging box respectively, the motor 42 is stopped, thereby using the angle plates 48, the sleeve 410 and the cross plate 49 in the limiting mechanism 4 to squeeze, limit and fix the vegetable packaging box in the car.
