Technical Field

[0001] This utility model relates to the field of heat treatment workshops, and in particular to a material delivery trolley for heat treatment workshops. Background Technology

[0002] The heat treatment workshop is a key sub-sector in manufacturing, primarily involving heat treatment operations on metallic materials or components. Through processes such as heating, holding, and cooling, the microstructure of the material is altered, thereby improving its properties, such as strength, hardness, toughness, and wear resistance. This field encompasses various heat treatment processes, such as quenching, tempering, normalizing, and annealing, and is widely used in numerous industries including machinery manufacturing, automotive, aerospace, and mold making. It plays a crucial role in improving product quality, extending service life, and meeting the demands of different operating conditions, and is an important link in ensuring high-quality development of industrial production.

[0003] Material delivery carts in heat treatment workshops are transportation tools serving the workshop. They are mainly used to transport metal materials or parts awaiting processing within the workshop, accurately delivering them from the storage area or previous process to the heat treatment equipment. They can also transport processed materials to the next stage, improving material transportation efficiency and ensuring the smooth operation of the heat treatment process. They are crucial equipment for workshop logistics automation. However, current material delivery carts in heat treatment workshops have the following shortcomings: First, their size and storage capacity are poor. During non-working hours or when space is limited, conventional carts take up a lot of space and are difficult to place properly. The lack of a foldable design hinders convenient storage for staff and affects workshop space utilization. Second, their ergonomic design is insufficient. The fixed handle height cannot adapt to the operating habits of employees of different heights, and prolonged use can easily cause physical fatigue, reducing work efficiency and comfort.

[0004] In response to this technical problem, this application proposes a material delivery trolley for a heat treatment workshop. Utility Model Content

The two base plates 1 are rotatably connected by a first rotating shaft 2. Two metal tubes 4 are rotatably connected to the rear side of the right base plate 1 by a second rotating shaft 11. A handle 3 is slidably connected between the two metal tubes 4, and the base plate 1 is moved by pushing it through the handle 3. Two slots are provided on the right side of the right base plate 1. A fixing plate 12 is fixedly connected to the bottom side of the right base plate 1. A plug-in plate 15 is fixedly connected to the bottom side of the left base plate 1. (Refer to...) Figure 2 Four metal rods 5 are fixedly connected to the outer wall of the metal tube 4. The front end of the four metal rods 5 and the rear end of the four metal rods 5 are fixedly connected to metal plates 6. Sliding rods 7 are slidably connected inside the metal plates 6. Limiting rods 9 are fixedly connected to the rear end of the front sliding rods 7 and the front end of the rear sliding rods 7. The two limiting rods 9 are mirror images of each other and pass through the metal tube 4, handle 3 and metal tube 4 in sequence. By passing the limiting rods 9 through the metal tube 4 and handle 3, the position of handle 3 is fixed on the metal tube 4 to prevent handle 3 from sliding in the metal tube 4. A spring 8 is sleeved on the outer wall of the sliding rod 7. One end of the spring 8 is connected to one side of the metal plate 6 and the other end of the spring 8 is connected to one end of the limiting rod 9. Pull rings 10 are fixedly connected to the front end of the front sliding rod 7 and the rear end of the rear sliding rod 7. The spring 8 is used to press the limiting rod 9 against the metal tube 4 and handle 3, and the pull rings 10 are used to pull the sliding rod 7 to disengage the limiting rod 9 from the metal tube 4 and handle 3.

[0028] Reference Figure 5A positioning rod 24 is slidably connected inside the slot. The two positioning rods 24 are mirror images of each other and pass through the base plate 1, the metal tube 4, and the base plate 1 in sequence. By inserting the positioning rod 24 into the base plate 1 and the metal tube 4, the metal tube 4 is fixed in place to prevent it from rotating. The rear end of the front positioning rod 24 and the front end of the rear positioning rod 24 are rotatably connected to a ring 16. A snap-fit ​​groove is provided on the bottom side of the slot. A snap-fit ​​rod 17 is fixedly connected to the outer wall of the ring 16. A baffle 18 is slidably connected inside the snap-fit ​​groove. The snap-fit ​​rod 17 is engaged inside the snap-fit ​​groove. The baffle 18 is located above the snap-fit ​​rod 17. The ring 16 rotates the snap-fit ​​rod 17 into the snap-fit ​​groove, and one end of the baffle 18 slides into the snap-fit ​​groove, so that the baffle 18 is above the snap-fit ​​rod 17 to prevent the snap-fit ​​rod 17 from disengaging from the snap-fit ​​groove. Thus, the snap-fit ​​rod 17 is fixed in the base plate 1 and the metal tube 4. (Refer to...) Figure 3 , Figure 4 and Figure 6 A fixed tube 13 is fixedly connected between the two fixed plates 12 on the left and right sides. A plug rod 14 is slidably connected inside the fixed tube 13. The plug rod 14 is inserted into the plug plate 15. By inserting the plug rod 14 into the plug plate 15, the two base plates 1 are fixed together to prevent the two base plates 1 from rotating and causing the goods to tip over when the trolley is going up or down a slope. A threaded rod 19 is threadedly connected inside the plug rod 14. A handle 20 is rotatably connected to the left end of the fixed tube 13. The left end of the threaded rod 19 is rotatably connected inside the fixed tube 13 and fixedly connected inside the handle 20. The handle 20 is used to rotate the threaded rod 19 and drive the plug rod 14 to slide.

[0029] Working principle: First, the two base plates 1 on the folded trolley are rotated to a flat state via the first pivot 2, unfolding the two base plates 1. Then, the handle 20 is rotated to rotate the threaded rod 19, which in turn drives the insertion rod 14 to slide, allowing the insertion rod 14 to insert into the insertion plate 15. Next, the metal tube 4 is rotated to a perpendicular state with the base plates 1. Then, the latching rod 17 is slid to push the positioning rod 24 into the metal tube 4 and the base plate 1. The latching rod 17 is then rotated to engage with the latching groove. Finally, the baffle 18 is slid so that one side of it is inserted into the latching groove, positioning the baffle 18 above the latching rod 17 to prevent the latching rod 17 from disengaging from the latching groove. This allows the latching rod 17 to be fixed in the base plate 1 and the metal tube 4. Then, the operator can slide the handle 3 to easily push the trolley. To do this, first pull the ring 10 to pull the sliding rod 7, causing the limiting rod 9 to disengage from the metal tube 4 and the handle 3. Then slide the handle 3 to the appropriate height. Afterward, release the ring 10, allowing the limiting rod 9 to insert into the metal tube 4 and the handle 3 under the action of the spring 8, thus fixing the handle 3 in place on the metal tube 4. The goods can then be placed on the base plate 1 for movement. When the trolley needs to be folded, simply reverse the above process; details are omitted here.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
