Description

Technical Field

[0001] The utility model relates to the technical field of steel bladders, in particular to a steel bladder which is corrosion-resistant and not easily deformed. Background Art

[0002] Steel bladder refers to a steel container, shell or structure used to store or carry objects.

[0003] Chinese patent: CN202223408803.X discloses a stainless steel cup liner. To solve the problem that the current stainless steel cup liner uses a ceramic liner and has a poor thermal insulation effect, a stainless steel liner is used with a food-grade Teflon coating to improve the thermal insulation effect of the liner.

[0004] Although the inner liner made of stainless steel in the above-mentioned prior art can improve the heat preservation effect, there are still some problems that need to be solved in actual use. In particular, when the cup accidentally falls, due to the lack of an effective protective structure in the inner liner, when the cup collides with the ground, the impact force generated can easily cause the inner liner to deform or even break, thereby reducing the service life of the inner liner. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0015] As a preferred solution of the corrosion-resistant and non-deformable steel bladder described in the utility model, the cross-section of the connecting piece is U-shaped and welded to the top of the outer bladder and the inner bladder.

[0016] As a preferred solution of the corrosion-resistant and non-deformable steel bladder described in the utility model, reinforcing ribs are arranged between the inner bladder and the outer bladder, and the reinforcing ribs are components made of rigid material.

At the same time, with the arrangement of the connecting parts, the reinforcing ribs and the thermal insulation layer, the impact force can be reduced when the steel liner collides with the ground regardless of the top or bottom, thereby achieving the protection effect on the inner liner.

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Reference Figure 1 to Figure 2 , is an embodiment of the utility model, which provides a corrosion-resistant and non-deformable steel bladder, including a steel bladder 1, the steel bladder 1 includes an inner bladder 12 and an outer bladder 11, the inner bladder 12 and the outer bladder 11 form a double-layer structure, a cavity is formed therebetween, and a buffer component 3 is provided in the cavity between the inner bladder 12 and the outer bladder 11, the buffer component 3 is used to buffer the steel bladder 1 when it is hit, the inner bladder 12 is sprayed with a corrosion-resistant coating, the corrosion-resistant coating is preferably made of polyethylene, and can also be made of polypropylene or polyethylene, the polyethylene coating has good high temperature resistance and can have a certain corrosion resistance, preventing water or other drinking products from corroding the inner bladder 12.

[0031] Reference Figures 2 to 4The buffer component 3 includes an elastic layer 31 sleeved on the outside of the inner liner 12. The elastic layer 31 can be connected to the outside of the inner liner 12 by adhesive but is not limited thereto. The elastic layer 31 is preferably made of rubber, and can also be made of silicone or hard plastic. A plurality of protrusions 311 are arranged at equal intervals on the outside of the elastic layer 31 along its circumferential direction, and the protrusions 311 are arranged in multiple groups along the length direction of the elastic layer 31. The protrusions 311 and the elastic layer 31 are made of the same material. A plurality of arc blocks 32 are arranged inside the outer liner 11 along its circumferential direction, and the arc blocks 32 are arranged in multiple groups along the length direction of the outer liner 11. The multiple groups of arc blocks 32 are staggered with the protrusions 311 and there are certain gaps. The arc blocks 32 are made of rigid material.

[0032] In this embodiment, when the steel liner 1 falls and its outer liner 11 collides with the ground, the outer liner 11 squeezes the arc blocks 32 inward. Since the arc blocks 32 and the protrusions 311 are arranged in a staggered manner, when squeezed, the arc blocks 32 and the protrusions 311 collide with each other and squeeze the protrusions 311, so that the elastic layer 31 is deformed, thereby converting the impact energy into deformation energy, thereby slowing down the propagation of the impact force, and multiple groups of protrusions 311 and multiple groups of arc blocks 32 can disperse the impact force to a larger surface area, thereby reducing the local impact pressure and reducing the impact on the inner liner 12, thereby preventing the inner liner 12 from being deformed, thereby increasing its service life;

[0033] Furthermore, since there is a certain gap between the multiple groups of protrusions 311 and the arc-shaped blocks 32 , there is a thin gas in the gap, which can reduce heat conduction, thereby effectively improving the heat preservation effect of the steel bladder 1 .

[0034] Reference Figure 2 and Figure 5 A connecting piece 2 is provided at the top of the inner liner 12 and the outer liner 11. The cross section of the connecting piece 2 is U-shaped, and the outer liner 11 and the inner liner 12 are connected by welding.

[0035] In this embodiment, the U-shaped connector 2 can provide additional structural support to strengthen the connection between the inner liner 12 and the outer liner 11. At the same time, the U-shaped connector 2 has a certain elasticity due to its shape. Therefore, when its end is downward in contact with the ground, it can reduce the propagation of impact force to a certain extent, further preventing the inner liner 12 from deforming.

[0036] Reference Figure 6 A reinforcing rib 13 is provided between the inner liner 12 and the outer liner 11, and the reinforcing rib 13 is used to provide supporting force.

[0037] In this embodiment, by setting the reinforcing ribs 13, a stronger connection can be formed between the bottom of the inner liner 12 and the outer liner 11, thereby increasing the stability of the overall structure, improving its bearing capacity and durability, and at the same time increasing the compressive resistance of the bottom of the inner liner 12 and the outer liner 11, dispersing the force on the bottom, and reducing the risk of deformation or rupture of the bottom.

[0038] Reference Figure 6 A heat-insulating layer 33 is provided between the bottom of the inner liner 12 and the outer liner 11 . The heat-insulating layer 33 is a component made of foam material. The heat-insulating layer 33 wraps the reinforcing rib 13 .

[0039] In this embodiment, the insulation layer 33 made of foam material has certain heat insulation performance, which can effectively improve the insulation performance of the steel liner 1, and the insulation layer 33 made of foam can form a buffer layer on the outside of the reinforcing rib 13. When the bottom of the steel liner 1 collides with the ground downward, the insulation layer 33 can effectively absorb the impact force, which helps to reduce the impact on the reinforcing rib 13 and the bottom of the inner liner 12, further prevent the inner liner 12 from deformation, and effectively increase its service life.
