Description

Hollow metal chopsticks structure improvement

This creation is about a kind of chopsticks, especially a hollow metal chopstick structure which is formed by bending and welding a metal plate and having a quadrangular cross section.

According to the current, generally hollow metal chopsticks are mostly made of a metal plate wound into a circular tubular welding, and then processed and formed into a circular tapered rod-shaped hollow metal chopstick having a grip portion and a clamping portion, and The hollow metal chopsticks are respectively provided with a circular arc convex portion, and the circular tapered metal hollow chopsticks are limited by the processing method, and the quality cannot be consistent, and each chopsticks produced has more or less thickness. The difference, and due to the circular tapered rod design, when the chopsticks are placed on the table, it is very easy to roll, and when the meal is often used, the chopsticks roll to the ground, and the grip and grip are not good. For food, the manufacturer has stamped and formed at least one plane of the grip portion. However, not only does the labor cost increase, but the stamping molding is difficult to accurately control the shape change, so that the quality of the hollow metal chopsticks is more inconsistent.

This creator has the disadvantages of the fact that the hollow metal chopsticks have the same quality, are easy to produce rolling, are not easy to hold and pick up food, and are based on the ideas of creation and trials. After the revision was improved, the creation was finally designed.

The present invention provides an improved structure of a hollow metal chopsticks The metal plate is bent and welded to form a hollow quadrangular rod body. The rod body has a first end and a second end, and the first end is tapered toward the second end, and the rod body is disposed near the first end. The grip portion is provided with a clamping portion near the second end. The first end of the rod body is provided with a first sealing piece for sealing, and the second end of the rod body is provided with a second sealing piece for sealing or direct spot welding.

The main purpose of this creation is that it is formed by bending and welding metal plates, which not only ensures the same quality, but also the design of the hollow quadrilateral rod, which is not easy to roll when placed on the tabletop, and can avoid the chopsticks rolling down when eating. The condition on the ground, as well as the convenience of holding and gripping food.

Referring to the first, second, third and fourth figures, the hollow metal chopsticks of the present invention are improved, and the hollow metal chopsticks are bent and welded by a sector-shaped metal plate A1 to form a hollow quadrilateral rod 1, which is The body 1 has a thicker first end 11 and a thinner second end 12, and is tapered from the first end 11 toward the second end 12. The first end 11 has an inner hole 111. The second end 12 has an inner hole 121. The rod body 1 is provided with a grip portion 13 near the first end 11, and a clamping portion 14 is disposed adjacent to the second end 12. The first end 11 of the rod body 1 utilizes a first end. A sheet 15 is closed, and the second end 12 of the rod body 1 is closed by a second sealing sheet 16 which is integrally formed on the upper end and the lower end of the sector-shaped metal plate A1, respectively. The first sealing piece 15 is slightly smaller than the inner hole 111 of the first end 11 of the rod body 1. The second sealing piece 16 is slightly smaller than the inner hole 121 of the second end 12 of the rod body 1, and is bent and welded on the fan-shaped metal plate A1. After the hollow quadrilateral body 1 is bent, the first sealing piece 15 and the second sealing piece 16 are respectively bent and placed in the inner hole 111 of the first end 11 of the rod body 1 and the inner hole 121 of the second end 12 is welded and closed. Again Flattening, the first sealing piece 15 and the second sealing piece 16 are seamlessly joined to the first end 11 and the second end 12 of the rod body 1, and the corners of the hollow metal chopsticks are rounded 17.

Furthermore, as shown in the fifth and sixth figures, the first cover 15 is disposed approximately the same size as the first end 11 of the shaft 1, and the second cover 16 is disposed approximately opposite the second end of the shaft 1. 12 is the same size, and after the fan-shaped metal plate A1 is bent and welded to form the hollow quadrilateral rod body 1, the first sealing piece 15 and the second sealing piece 16 are respectively bent and placed on the first end 11 of the rod body 1 and The end faces of the two ends 12 are welded and closed, and then flattened to form a seamless joint between the first cover 15 and the second cover 16 and the first end 11 and the second end 12 of the rod 1.

Or as shown in the seventh and eighth figures, the first cover 15 is set to be slightly smaller than a separate member of the inner hole 111 of the first end 11 of the rod body 1, the second sealing piece 16 is disposed as a separate member slightly smaller than the inner hole 121 of the second end 12 of the rod body 1, and is bent and welded on the sector-shaped metal plate A1. After the hollow quadrilateral body 1 is respectively inserted into the inner hole 111 of the first end 11 of the rod body 1 and the inner hole 121 of the second end 12 is welded and closed, and then smoothed to make the two pieces 15 and 16 and the rod The first end 11 and the second end 12 of the body 1 meet to form a seamless joint.

Or as shown in the ninth and tenth figures, the first cover 15 is disposed as a separate member approximately the same size as the first end 11 of the shaft 1, and the second cover 16 is disposed approximately the second with the shaft 1 The end 12 is of the same size and has a separate member, and after the fan-shaped metal plate A1 is bent and welded to form the hollow quadrilateral body 1, respectively, the end faces of the first end 11 and the second end 12 of the rod body 1 are respectively welded and closed, and then ground. Flattening, the two sheets 15, 16 are brought into a seamless joint with the first end 11 and the second end 12 of the rod 1.

Moreover, the second end 12 of the hollow metal chopstick body 1 can be closed by welding with the second sealing piece 16 as described above, or can be directly closed by spot welding without using the second sealing piece 16 and then smoothed. .

In addition, the clamping portion 14 of the hollow metal chopstick can be provided with a plurality of anti-slip ring grooves 141 as shown in FIG. 11 to make it easier to grip the food.

From the structure of the above specific embodiment, the following benefits can be obtained:

1. The improved hollow metal chopsticks structure of the present invention is formed by bending and welding a metal plate, which not only ensures uniform quality, but also the design of the hollow quadrangular rod 1 so that the hollow metal chopsticks are placed on a plane (such as a table top) at rest. By placing one side of the quadrangular rod 1 on the plane, the hollow metal chopsticks are stably placed on the plane, which is not easy to cause rolling, and is convenient for the user to grasp and grip the food, thereby giving Better practical benefits, product market Increased competitiveness.

2. The structure of the hollow metal chopsticks is improved, the overall structure is simple, the production is convenient and fast, the working time cost is reduced, and the economic benefits are met.

In summary, this creation has indeed reached a breakthrough structure, and has improved content of creation, while at the same time achieving industrial use and progress. When complying with the provisions of the Patent Law, it proposes a new type of patent application according to law. The census review committee granted legal patent rights and was praying.
