Benefits of technology

The present invention provides a joint part and tank body that are connected with each other using a stamping fastening structure. This leads to high production efficiency, low cost, and no welding slag during production. The stamping fastening structure ensures a tight connection between the joint part and tank body. The positioning structure on the joint part improves the positioning effect when the tank cap is screwed to prevent the tank mouth from rotating or falling off. The pressure-proof protective structure on the joint part also acts to protect the tank mouth from deformation or falling off when the tank cap is pressed down.

Problems solved by technology

Herein, the soldering is low in efficiency and high in cost.
Besides, it is easy to generate some welding slag during a production process, in which case the chemical tank looks unbeautiful.
Furthermore, the fastening strength of stamping in the conventional chemical tank is relatively low.
When screwing a tank cap, the tank mouth may thus displace and even fall off easily.

Embodiment Construction

[0012]Referring to FIG. 1, it is a structural diagram for a chemical tank of the present invention. The chemical tank comprises a tank mouth 1 and a tank body 2, wherein the latter is formed by a combination of a tank body part 21, a tank top 22 and a tank bottom (not shown in the FIGURE) that are all made of metal sheet. The tank mouth 1 is mounted on the tank top 22, and it is comprised of a mouth body 11 and a joint part 12. The mouth body 11 is arranged with a spiral structure 111 on its outside surface, and the joint part extends vertically from the bottom of the mouth body 11. Besides, the mouth body 11 is made of metallic material.

[0013]The joint part 12 is similar to a laminar structure which is made of the same material as that of the mouth body 11. The joint part 12 is connected with the tank body 2 by a stamping fastening structure 3. Moreover, leakage-proof glue is provided between the joint part 12 and the tank body 2. During production, the tank mouth 1 is place on the...

Abstract

The present invention relates to a chemical tank comprising a tank body and a tank mouth. The tank body includes a tank body part, a tank top and a tank bottom. The tank mouth arranged on the tank top includes a mouth body and a joint part. A stamping fastening structure for connecting the joint part and the tank body is arranged therebetween. Further, a positioning structure is disposed at the junction of the joint part and the tank body. A pressure-proof protective structure located in the joint part and the tank top is provided on the periphery of the stamping fastening structure. Herein, the positioning structure acts to enhance the positioning effect. Besides, the pressure-proof protective structure plays a role of pressure-proof protection. The tank mouth and the tank top are produced by stamping fastening, thus achieving high production efficiency, low cost and high strength.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a metal container, and specifically to a chemical tank.BACKGROUND OF THE INVENTION[0002]In the conventional chemical tank, the fastening connection between its tank mouth and tank body is achieved by soldering or stamping. Herein, the soldering is low in efficiency and high in cost. Besides, it is easy to generate some welding slag during a production process, in which case the chemical tank looks unbeautiful. Furthermore, the fastening strength of stamping in the conventional chemical tank is relatively low. When screwing a tank cap, the tank mouth may thus displace and even fall off easily. A pressure-proof protection is also absent at the joint part between the tank mouth and the tank body of the conventional chemical tank. In this case, it is easy for the joint part and the tank body to deform and fall off when the tank cap is pressed down.SUMMARY OF THE INVENTION[0003]The objective of the present invention is to provi...
