Description

Improved structure of chemical tank

technical field

The utility model relates to an improved structure of a chemical tank, in particular to a tank body whose bottom cover is slightly larger than an upper cover seat, and the lower curling ring of the lower tank body presses against the lower curling ring of the upper tank body from inside to outside during stacking, That is to reduce the possibility of dumping after stacking, and also prevent the tank body from being deformed or the lid jumping when subjected to external force.

Background technique

Common cans and barrel structures (such as paint cans) with lids on the market, as shown in Figure 5, a tank structure with a top cover, which includes: a tank body 30 and a lid body 40, A can body 30 is formed by riveting the can body portion 31, the bottom cover 32 and the upper cover 33. The riveted edges of the can body portion 31 and the bottom cover 32 are curled to form a curling portion 34. In addition, the can body portion 31 and the upper cover Seat 33 is also riveted to form a curling portion 35, and inwards extending concavely at curling portion 34 is provided with fastening groove 36 and offers a can mouth, and this tank body portion 31 is a smooth surface again, and curling portion 34,35 and Can body portion 31 forms an upright surface of tank body 30, and a cover body 40 is a circular disk body, and its outer edge is concavo-convex to form a fastening ring 41, and this cover body 40 can be used for fastening ring 41 and tank body 30 The fastening groove 36 is closed and fixed, and the tank body 31 and the bottom cover 32 form an accommodating space, and the solution to be preserved can be placed therein, and the fastening ring 41 of the cover body 40 is sealed and fixed on the upper cover seat 33 fastening groove 36.

Looking at the above existing structure in detail, it is not difficult to find that it still has some deficiencies, the main reasons are as follows:

1. The diameter of the crimped portion 34 of the bottom cover 32 is equal to the crimped portion 35 of the upper cover 33, and its body portion 31 forms a vertical surface, and the crimped portion 34 of the lower tank body 30 is directly against the upper tank in the stack. The crimp portion 35 of the body 30 makes it easy for the stacked cans 30 to fall over when subjected to an external force, resulting in deformation or cap jumping.

Two, the tank body 31 is a smooth surface, and the crimps 34, 35 and the tank body 31 form a vertical surface of the tank body 30, the structural strength of the tank body 30 is insufficient, so the thickness of the tank body 30 must be increased, namely The material cost of the tank body 30 and the cover body 40 is increased.

In view of this, the creators have been engaged in the manufacturing, development and design of related products for many years, aiming at the above-mentioned goals, after detailed design and careful evaluation, they finally have a truly practical creation.

Utility model content

Technical problems to be solved:

In the existing tank structure with a top cover, the diameter of the curled part of the bottom cover is equal to the curled part of the upper cover, and the body part of the tank forms a vertical surface, so that the structural strength of the tank body is insufficient, and the other parts in the stacking The crimped part of the lower tank body is directly against the crimped part of the upper tank body, so that when the stacked tank body is subjected to external force, the tank body is easy to deform and topple over, resulting in deformation or jumping of the cover. This is the purpose of this utility model. Solve the technical problem point.

Technical features to solve the problem:

An improved structure of a chemical tank of the utility model includes: a tank body and a cover body, a tank body is formed by riveting the tank body, a bottom cover and an upper cover seat, and the riveting of the tank body and the bottom cover The edges are crimped to each other to form a lower crimped ring, and the can body and the upper cover seat are also riveted to form an upper crimped ring. The upper curling ring extends inward and is provided with a fastening groove and a tank mouth. The tank body ring is provided with multiple rings of reinforcing grooves, and the reinforcing grooves form a concave-convex wavy plane along the tank body, and The diameter of the lower crimping ring is larger than that of the upper crimping ring. A cover body is a circular disc body, and its outer edge is concave-convex to form a fastening ring. The cover body can be closed and fixed by the fastening ring and the fastening groove of the tank body. shape, the tank body and the bottom cover form a storage space, and the solution to be preserved can be placed in it, and the fastening ring of the cover body is sealed and fixed in the fastening groove of the upper cover seat, when the chemical tank is transported and When stocking, due to excessive quantity or insufficient space, it needs to be stacked to reduce the waste of space. The size of the bottom cover of the tank body is larger than the cover body, that is, the lower crimping ring is larger than the upper crimping ring, and more than two tanks should be used. When stacking upwards, the tank body at the lower end presses against the bottom cover of the upper tank body with the slightly shrunk upper cover seat, and the lower crimping ring of the lower tank body presses against the lower crimping ring of the upper tank body from the inside to the outside, and the stacking is completed Effect.

Efficacy compared to previous techniques:

1. The diameter of the lower crimping ring is larger than that of the upper crimping ring. During stacking, the lower crimping ring of the lower tank body presses against the lower crimping ring of the upper tank body from the inside to the outside, which reduces the possibility of dumping after stacking. When subjected to external force, the tank body will not be deformed or the cover will jump.

2. The can body ring is provided with multi-circle reinforcing grooves, and the reinforcing grooves form a concave-convex wavy plane along the can body, and the diameter of the lower crimp ring is larger than the upper crimp ring, so that the cover body The diameter becomes smaller, thereby maintaining sufficient structural strength, and reducing the material cost of the tank body and the cover body.
