Description

Technical Field

[0001] The utility model relates to the technical field of injection molding barrels, in particular to a special injection molding barrel for chemical coatings which is easy to carry. Background Art

[0002] Injection molded barrels are mostly made of polyethylene, polypropylene and other plastics through blow molding, injection molding, vacuum forming and other methods. Due to their excellent performance, they are often used for the storage and transportation of various liquids. Existing injection molded barrels are often only equipped with handles and other parts for carrying a single barrel. The carrier can only carry a single barrel at a time, which has poor carrying efficiency. In addition, since the carrying method consumes a lot of physical strength, the carrier's physical strength is limited, which reduces the carrier's effective working time and further reduces the carrying efficiency.

A docking rod 22 is provided at the bottom end of the connecting rod 7. A rotating groove 21 corresponding to the rotating hole 10 is provided on the docking rod 22. The rotating groove 21 is rotatably connected to the rotating hole 10. The fixing plate 9 has a certain elasticity to allow the rotating groove 21 to be squeezed into and squeezed out of the notch 11. A handle 12 is provided at the top of the connecting rod 7. The bottom of the barrel body 1 is detachably connected to the top of the bottom plate 8. Universal wheels 13 are respectively provided at the four corners of the bottom of the bottom plate 8. A groove 14 corresponding to the shape of the bottom of the barrel body 1 is provided on the top of the barrel cover 3. An anti-corrosion layer 15 is provided on the inner wall of the barrel body 1.

[0022] The carrier can carry a single barrel by hand, pull a single barrel by hand, and pull multiple barrels by hand. The operation is simple and labor-saving. When the carrier carries a single barrel by hand, it is not necessary to install the connecting rod 7 and the bottom plate 8. It is only necessary to hold the handle 6 to lift the barrel body 1. When the carrier pulls a single barrel by hand, the docking rod 22 is installed on the fixing plate 9 to complete the installation of the connecting rod 7, and the bottom plate 8 is installed on the bottom of the barrel body 1. Then, the handle 12 is held to pull the bottom plate 8 to move. When the carrier pulls multiple barrels by hand, after completing the installation of the connecting rod 7 and the bottom plate 8, the bottom end of the barrel body 1 is aligned with the bottom of the barrel body 1. Multiple barrels can be stacked by means of the groove 14 on the barrel cover 3, and then the handle 12 can be held to pull the bottom plate 8 to move; since the height of the barrel body 1 is generally lower than the height of the hand of the carrier when standing, the notch 11 is set at the lower part of the rotating hole 10 to prevent the carrier from accidentally pulling the rotating groove 21 out of the rotating hole 10 when pulling the connecting rod 7; the groove 14 is used to limit the position of the barrel body 1 above the barrel cover 3 to reduce the probability of the barrel body 1 sliding off; an anti-corrosion layer 15 is provided on the inner wall of the barrel body 1 to facilitate the storage of chemical coatings with a certain degree of corrosiveness.

[0023] Furthermore, a threaded column 16 is provided on the top of the base plate 8, and a threaded groove 17 corresponding to the threaded column 16 is provided on the bottom of the barrel body 1. The connection between the base plate 8 and the barrel body 1 is achieved by threaded connection between the threaded column 16 and the threaded groove 17. A protrusion 18 corresponding to the threaded groove 17 is provided on the top of the barrel cover 3. When the injection molding barrels are stacked up and down, the protrusion 18 of the lower barrel cover 3 extends into the threaded groove 17 of the upper barrel body 1.

[0024] The connection between the bottom plate 8 and the barrel body 1 is achieved by threaded connection between the threaded column 16 and the threaded groove 17, which has a certain connection strength and is easy to assemble and disassemble. The protrusion 18 on the barrel cover 3 cooperates with the threaded groove 17 into which it extends, further enhancing the limiting effect of the barrel body 1 on the barrel cover 3.

[0025] Furthermore, support plates 19 are evenly arranged along the circumference of the bottom of the barrel cover 3. When the barrel cover 3 is covered on the barrel body 1, the support plates 19 extend into the barrel body 1 and the outer wall thereof abuts against the inner wall of the barrel body 1. The pressure on the barrel cover 3 is shared by the support plates 19 abutting against the inner wall of the barrel body 1, thereby improving the ability of the barrel cover 3 to resist deformation, thereby increasing the maximum number of injection barrels that can be stacked.

[0026] Further, a handle 20 is provided in the middle of the handle 6. The carrier can lift the handle 6 by holding the handle 20, which is convenient for the carrier to operate.

[0027] The working principle and use process of this utility model:

[0028] The transporter can choose whether to install the connecting rod 7 and the bottom plate 8 according to his own transport needs. When only a single barrel is needed to be transported and the chemical coating contained in the barrel is light in weight, the single barrel can be carried by hand. When the chemical coating contained in the barrel is heavy or multiple barrels need to be transported, the connecting rod 7 and the bottom plate 8 are installed, and the single barrel or multiple barrels can be transported by hand.

[0029] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
