Description

Technical Field

[0001] The utility model belongs to the technical field of transfer carts, in particular to a turnover box transfer cart with an automatic weighing function. Background Art

[0002] Turnover boxes, also known as logistics boxes, are widely used in the machinery, automotive, home appliance, light industry, electronics, and other industries. They are acid-resistant, alkali-resistant, and oil-resistant, non-toxic and odorless, and can be used to store food, among other things. They are easy to clean, provide convenient parts turnover, and neatly stacked for easy management. Their rational design and superior quality make them suitable for transportation, distribution, storage, and processing in factory logistics. They can be combined with a variety of logistics containers and workstation equipment, and can be used in various locations, including warehouses and production sites. As logistics management becomes increasingly important for many companies, turnover boxes help achieve the universal and integrated management of logistics containers, making them essential for modern logistics management for manufacturing and distribution companies.

[0003] A transfer cart is a unit-type mobile container equipped with four casters for transporting and storing materials. It is commonly used in large supermarket logistics distribution or logistics turnover between factory processes.

[0004] However, the existing transfer carts require workers to first move the turnover boxes onto the cart, then pull it to the weighing area, move the turnover boxes to the scale for weighing, and then move the goods onto the cart, pull it to the temporary storage area for goods, and take the goods down for storage. During the whole process, workers need to move and place turnover boxes many times, which is time-consuming and labor-intensive, with high work intensity, low work efficiency, and very inconvenient to use.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Example:

[0033] A turnover box transfer cart with automatic weighing function, such as Figure 1-5 As shown, it includes an outer frame 1, a fixed plate 2 is provided at the lower part of both sides of the outer frame 1, an inner frame 3 is provided above the outer frame 1, and inner supporting plates 4 are provided at the lower part of both sides of the inner frame 3. A handle rod 5 is rotatably provided at the rear end of the outer frame 1, and the handle rod 5 is connected to the inner frame 3 through a transmission rod 6. The handle rod 5 and the inner frame 3 are both rotatably connected to the transmission rod 6. The outer frame 1 and the inner frame 3 are both connected at both ends through a transmission plate 7. The outer frame 1 and the inner frame 3 are both rotatably connected to the transmission plate 7.

[0034] Furthermore, the transmission rod 6 is rotationally connected to the handle rod 5 and the inner frame 3 by rotating bolts.

[0035] Furthermore, the transmission plate 7 adopts a structure in which the height gradually increases from the rear to the front, with the rear lower end being rotatably connected to the outer frame 1 and the front upper end being rotatably connected to the inner frame 3 .

[0036] In a possible embodiment, movable wheels 9 are provided below the four corners of the outer frame 1 , and limit blocks 8 are provided on both sides above the rear end of the outer frame 1 .

[0037] Furthermore, the height of the moving wheel 9 is slightly greater than the height of the inner frame 3 , so that in the initial state, the horizontal section of the inner frame 3 is close to the ground.

[0038] In one possible embodiment, pin plate running track grooves 21 are provided at both the front and rear ends of the fixed plate 2, and gap adjustment pin plates 10 are inserted into the pin plate running track grooves 21. The gap adjustment pin plates 10 are fixedly connected to the inner support plate 4. A sensor fixing frame 11 is provided at the end of the gap adjustment pin plate 10 away from the inner support plate 4. A weighing sensor 12 is provided on the sensor fixing frame 11. Four sensor support frames 13 are also provided on the fixed plate 2. The sensor support frames 13 are arranged on the rear side of their corresponding weighing sensors 12. As the turnover box is lifted, the weighing sensor 12 falls on its corresponding sensor support frame 13.

[0039] Furthermore, the pin plate running track groove 21 does not contact the gap adjustment pin plate 10, and the pin plate running track groove 21 only serves as a channel to avoid affecting the weighing result.

[0040] Furthermore, the sensor fixing frame 11 and the sensor supporting frame 13 both adopt an L-shaped structure.

[0041] In a possible embodiment, a weighing display screen 14 is provided on the handle bar 5 for displaying weight information of the weighing sensor 12 .

[0042] In a possible embodiment, the inner support plate 4 adopts an L-shaped structure, the vertical section of which is connected to the inner frame 3, and the two inner support plates 4 are symmetrically arranged, and the horizontal sections of the two inner support plates 4 are oppositely arranged.

[0043] In a possible embodiment, a gap adjustment bolt hole 22 is also provided on the fixed plate 2. After the turnover box is lifted, the position of the inner support plate 4 is adjusted by passing the adjusting bolt through the gap adjustment bolt hole 22 to reduce the friction between the fixed plate 2 and the inner support plate 4 to ensure the accuracy of weighing.

[0044] By adopting the above technical solutions:

[0045] Through the lever principle, the lifting and lowering of the inner support plate 4 can be controlled, so that the turnover box can be quickly lifted and the turnover box can be weighed directly, which reduces the intermediate transportation links, saves time and effort, reduces the work intensity of the staff, improves work efficiency, and is more convenient to use.

[0046] Working principle, see Figure 1When in use, a small support frame is generally provided at the bottom of the turnover box for waterproofing, etc. This support frame is on the inner side of the bottom of the turnover box. Therefore, the horizontal sections of the two inner support plates 4 can fall on the bottom edge of the turnover box. At this time, the handle rod 5 is pulled backward, and the transmission rod 6 pulls the inner frame 3. At this time, the rotation connection between the transmission rod 6 and the outer frame 1 provides a fulcrum. Under the tension of the transmission rod 6, the inner frame 3 moves along the fulcrum. (In this process, the gap adjustment pin plate 10 slides in the pin plate running track groove 21, and the weighing sensor 12 gradually moves backward) At this time, the inner frame 3 moves backward and upward, thereby driving the inner support plate 4 to rise, and then driving the turnover box to rise.

[0047] When the inner frame 3 moves to contact with the limit block 8, the inner frame 3 rises to the highest point. At this time, the weighing sensor 12 falls on the sensor support frame 13. At this time, the inner support plate 4 is adjusted to the middle position through the gap adjustment bolt to reduce the friction between the fixed plate 2 and the inner support plate 4. At the same time, the connecting bolts between the transmission rod 6 and the inner frame 3 are removed. At this time, the four weighing sensors 12 support the inner support plate 4 and the turnover box, and the weight information of the turnover box is displayed on the weighing display screen 14.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
