Description

Strengthening structure of composite chopsticks

This creation is about the strengthening structure of a composite chopsticks, especially one that can effectively increase the strength to improve the product quality and prolong the service life.

In the past, chopsticks often used by people were mainly made of wood, but because wooden chopsticks are prone to mold when they are wet, and they are easy to bury dirt due to scratches after long-term use, most chopsticks currently on the market are It is made of metal, especially hollow stainless steel chopsticks.

The above-mentioned hollow stainless steel chopsticks are mainly made of stainless steel plates that are wound into a circular tube and then welded and then formed by grinding. It is also like the "Hollow Metal Chopsticks Structure Improvement" in the Republic of China Patent Publication No. M493943, which is welded after bending the metal plate Forming; there are also direct pressure forming on the metal tube by pressure. The hollow stainless steel chopsticks are made into a round tube or a square tube. However, the inside of the above-mentioned metal chopsticks is completely hollow. In actual use, it is easy to form dents or depressions on the metal surface due to slight external force touch, even after being subjected to a large external force. Bending, as a result, will not only reduce the quality of the product due to dents or depressions, it is not conducive to the user to hold the food, and will reduce the service life of the product.

For example, the applicant’s patent publication No. M458170 "Composite Chopsticks Reinforcement Structure" provides a method for wrapping a reinforcing rod on a metal sleeve and a plastic holding body. The structure in the metal sleeve is strengthened by reinforcing bars to prevent dents or depressions on the surface of the metal sleeve, and effectively improve the strength of bending resistance.

However, in the injection molding process of the composite chopsticks in the above-mentioned M458170 patent, the reinforcing rods need to be suspended and positioned between the inside and outside of the open end of the metal sleeve, and then the plastic holding body is wrapped at the same time. In the molding process, it is easy to affect the product quality due to the deviation of the reinforcing bar. Moreover, because the outer periphery of the reinforcing bar and the inner periphery of the metal sleeve are filled with plastic materials, the metal sleeve , The connection of heterogeneous materials between plastic materials and rods often has insufficient overall strength and bonding force, and cannot achieve the expected strength reinforcement effect. In view of this, in order to provide a structure that is different from the conventional technology and improve the above-mentioned shortcomings, the creators have accumulated years of experience and continuous research and development and improvement, and this creation was born.

One purpose of this creation is to provide a reinforced structure of composite chopsticks, so as to solve the problem that the conventional solid reinforcing rods cannot be effectively positioned during molding, and the expected strength and bonding force cannot be produced when the different materials are combined, but there will be strength Insufficient, it is easy to form dents, depression marks on the surface, or produce bending problems, which can effectively locate a strengthening structure and improve the bonding force between dissimilar materials to increase the surface and overall strength of the metal chopsticks. Improve product quality and extend service life.

In order to achieve the purpose of the above creation, the strengthening structure of the composite chopsticks set in this creation includes a first tube-shaped member, a filling part and a second tube-shaped member. Wherein, the first tubular member is positioned in the clamping portion, the first tubular member has at least one first slot; the filling portion is filled in the interior of the clamping portion and the at least one first slot for fixing the second A tubular member; and the second tubular member is fixed to The inside of the holding part, and the second tubular member is formed by extending one end of the first tubular member.

In implementation, the outer periphery of the first tubular member and the inner periphery of the clamping portion have the same cross-section, and the outer periphery of the first tubular member is smaller than the inner periphery of the clamping portion, so that the first tubular member is directly inserted and Positioned in the clamping part.

In implementation, the first slot is opened coaxially with the first tubular member, so that the first tubular member has radial flexibility.

In implementation, at least one radial perforation is further provided on the tube wall of the second tube-shaped member.

In implementation, the second tubular member further has a second slot, and the second slot is opened coaxially with the second tubular member, so that the cross-section of the second tubular member is C-shaped.

During implementation, one end of the filling part is filled in the inner and outer periphery of the second tubular member.

During implementation, one end of the filling part is extended from one end of the clamping part to form a gripping part.

When implemented, this creation further includes a necked section, one end of the necked section extends into a first tubular member, and the other end of the necked section extends into a second tubular member.

In implementation, the first tubular member has a first pipe with open ends, the necked section has an intermediate pipe, and the second tubular member has a second pipe with open ends. The first pipe, the intermediate pipe, and the second pipe follow The sequence is connected in a straight line.
