Technical Field

[0001] The utility model relates to the technical field of ton barrels, in particular to a ton barrel foot. Background Art

[0002] Ton barrels are containers for storing and transporting liquid substances, which greatly reduce the costs of production, storage, transportation and operation. Compared with traditional packaging, storage can save space, and forklifts can be used for loading and unloading, which reduces the trouble of manual handling. The base of the ton barrel is a frame component that supports the container inside the ton barrel, thereby enhancing the load-bearing strength of the container inside the ton barrel.

[0003] Among them, the announcement number CN204624378U is called an IBC ton barrel bottom foot corner protector, which includes a corner protector body, and the upper surface of the corner protector body is symmetrically provided with two upper reinforcing rib components, and the angle between the two upper reinforcing rib components is 55 to 65 degrees; a plurality of back reinforcing ribs are arranged along the height direction on the side of the corner protector body; a circular groove is arranged in the center of the side of the corner protector body; side ears are symmetrically arranged at both ends of the side of the corner protector body, and the side ears are in an inverted cone shape. When using the utility model, the side ears adopt an inverted cone shape to increase the pressure on the corner protector body in the positive direction; the back reinforcing ribs are arranged, and the front circular reinforcing ribs are formed by setting the circular grooves; by setting the side ears in an inverted cone shape, it saves materials and reduces manufacturing costs, and can also improve the strength of the corner protector body. The utility model has the advantages of simple structure, reasonable arrangement, and low manufacturing cost.

[0004] The above-mentioned prior art simply utilizes corner protectors that adapt to the shape of the four corners of the ton barrel container to strengthen the load-bearing capacity of the ton barrel container. However, when the container is placed on the bottom of the outer frame, there will still be a gap between the bottom foot and the four corners of the container. During transportation, the container will vibrate, causing slight collisions between the bottom foot and the container, causing wear and damage to the four corners of the container, which is not conducive to reinforcing, locking and shockproofing the container. Therefore, we propose a ton barrel bottom foot to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 5 The utility model provides the following technical solutions: a ton barrel foot, comprising a lower support frame 1, the four corners of the lower support frame 1 are equipped with support feet 2, the upper end of the support feet 2 is connected to the upper support frame 3, and the four corners of the upper support frame 3 are equipped with fixed seats 7; the side wall of the fixed seat 7 is elastically connected to the fixed corner guard 5 through the first spring 4, the outer side of the fixed corner guard 5 is connected to the moving rod 6, and the lower side of the moving rod 6 is provided with a positioning hole 19; the support foot 2 is rotatably connected to the rotating shaft 8, the outer side of the rotating shaft 8 is connected to the cam 9, the upper side of the cam 9 is equipped with a fixed column 10, the interior of the fixed column 10 is connected to the second spring 11, the upper end of the second spring 11 is connected to the positioning rod 12, and the outer side of the positioning rod 12 is equipped with a convex plate 13;

[0025] The fixed corner guard 5 is an arc-shaped structure, and the upper end surface of the fixed corner guard 5 is inclined to avoid the fixed corner guard 5 from obstructing the inner container when the inner container is moved down and placed. The fixed corner guard 5 is smoothly pushed to move so that it adapts to the size of the inner container and fits tightly with the four corners of the inner container; the moving rod 6 penetrates the side wall of the fixed seat 7 and is slidably connected to the fixed seat 7. Positioning holes 19 are evenly spaced on the lower side of the moving rod 6. The moving rod 6 can be used to support the fixed corner guard 5 while stabilizing the movement of the fixed corner guard 5, and the position of the fixed corner guard 5 is locked by fixing the moving rod 6; the positioning rod 12 and the positioning hole 19 are snap-fitted, and the positioning rod 12 forms an elastic structure with the fixing column 10 through the second spring 11, which can fix the moving rod 6 to prevent it from moving on its own;

[0026] The inner container is placed on the upper support frame 3, and the four corners of the inner container are placed on the fixed seat 7 respectively. When the inner container gradually moves downward, the fixed corner guard 5 can be pushed so that the fixed corner guard 5 squeezes and accumulates force on the first spring 4, and at the same time drives the moving rod 6 to slide on the fixed seat 7, so that the fixed corner guard 5 adapts to the size of the inner container and fits closely with the inner container to prevent the inner container from shaking, and presses the convex plate 13 downward to control the positioning rod 12 to slide in the fixed column 10. The positioning rod 12 presses and accumulates force on the second spring 11, and at the same time applies force to drive the fixed column 10 to drive the cam 9 to rotate, and moves the positioning rod 12 to the position of the moving rod 6. Release the pressure on the convex plate 13, and the second spring 11 can control the positioning rod 12 to move up and reset, so that the positioning rod 12 is stuck in the positioning hole 19 at the corresponding position, and the position of the moving rod 6 is locked, thereby stabilizing the fixed protection of the inner container by the fixed corner guard 5;

[0027] The outer side of the fixed seat 7 is connected to a gas cylinder 14, the interior of the gas cylinder 14 is slidably connected to a piston 15, the upper side of the piston 15 is connected to a mobile frame 16, the lower end of the gas cylinder 14 is connected to an air pipe 17, one end of the air pipe 17 is connected to a suction cup 18; the position of the convex plate 13 and the position of the mobile frame 16 are arranged correspondingly to each other, and the mobile frame 16 is a "7"-shaped structure. When the positioning rod 12 moves, the convex plate 13 is used to synchronously drive the mobile frame 16 to move, control the movement of the piston 15, and adjust the air pressure in the suction cup 18;

[0028] When the positioning rod 12 moves up, the convex plate 13 can push the movable frame 16 at the corresponding position to move up, so that the movable frame 16 drives the piston 15 installed at the lower end to slide in the air cylinder 14, and the suction cup 18 is sucked through the air pipe 17. The suction cup 18 negatively absorbs the four corners of the inner container, further stabilizes the inner container, and fixes and protects the four corners of the inner container. When the inner container needs to be taken out, it is necessary to press the positioning rod 12 downward to move the positioning rod 12 out of the positioning hole 19, and control the cam 9 to rotate so that the position of the positioning rod 12 is staggered with the position of the movable rod 6, and the lock of the positioning rod 12 is released. Then, the movable frame 16 is pressed downward to control the piston 15 to move downward, and the air flow is filled into the suction cup 18. The negative pressure adsorption of the suction cup 18 on the inner container is released, and the inner container can be removed.
