Abstract

The invention is about screw and nuts without thread, which makes screw tightly get together with nut by magnetic attraction and tenon, mortise to complete locking screw and nut closely. It is convenient and quick to use.

Description

Magnetic unthreaded screw nut

This creation uses the principle of magnetic anisotropy and the card to replace the mechanical rotation of the general screw nut to complete the locking function. New applications have been expanded in magnetism. Because it is convenient and quick to use, it can be widely used in assembling toys, especially when a built-in toy requires a lot of screws.

The general screws and nuts must be threaded with the screws and nuts to lock the screws in a rotating manner. The rotation time is long and it is not suitable for use on toy blocks.

In recent years, with the rapid development of China's economy and the improvement of people's living standards, the toy industry has also developed rapidly, showing diversification and intellectual development.

Among them, the assembled toys are favored by many children, and even teenagers love it. Assembled toys, some of which are the same material into a variety of different models. This is more conducive to the development of the intelligence of young people and children. Therefore, assembled toys have become more and more popular.

However, since the assembled toys need to be assembled in groups, the general practice of the toy is to screw the parts together and form a whole. In this way, the group needs to install a lot of screws for a toy, and some toys even have to be loaded with 40. ~50 screws and nuts, so the group of screws takes up most of the assembly time, which will make teenagers and children lose interest. The appearance of the traditional screw nut is shown in Figure 8. Frequent disassembly of conventional screws can cause the head of the screw to become blurred, become non-removable, or the screws are obsolete. These will be an obstacle to the assembly of toys into more perfect intellectual toys.

Thus, this creation provides an excellent solution, using a cassette and two or more magnets to each other. Strong attraction to achieve the purpose of locking. There are always two poles in a magnet: the N pole and the S pole, and follow the same laws of physical exclusion. Therefore, the creation and disassembly of the assembled toy card and the two magnets or the plurality of magnets achieve the purpose of assembling and disassembling the assembled toy.

As shown in Fig. 1, the rectangular parallelepiped magnet is fixed on the bottom of the plastic screw and the nut, and the screw 109 and the nut 106 are respectively provided with the cymbal 102 and the boring hole 103, and the screw tweezer must be aligned with the boring hole of the nut to be inserted, because the creation Screws and nuts are not threaded, so you can insert the screws to the end without turning them. The nut is designed to be screwed into the nut to achieve a fixed function as long as the screw is inserted into the nut and rotated. The polarity of the magnet on the screw nut is such that the screw and the nut have the maximum repulsive force when the tweezers and the cavities are aligned. After the screw is inserted into the bottom, the screw is rotated by an angle to become a screw, and the magnet on the nut has the largest suction force and is not easy to loosen. Therefore, the fixing of the screw and the nut of the present invention not only has the mechanism of the latch but also the magnetic force to join the screw and the nut together. When the screw is to be separated from the nut, simply rotate the screw to the position where the cymbal is aligned with the boring hole, and the repulsion of the magnet can be used to separate the two.

The creation is divided into two parts: screw and nut. The nut design is shown in Figures 2, 3 and 4 respectively. , side, top view, similar to a normal nut but without threads. Moreover, unlike the general nut, the bottom is sealed and a magnet 107 is mounted on the bottom. In the upper view, it can be seen that the hole of the nut opens a hole 103, which can be aligned with the dice on the screw, and the dice of the screw must be aligned. This hole can be inserted. On the way of side view, we can see that the bottom space of the nut is enlarged. After the tweezers of the screw are inserted into the bottom of the nut, the screw can be pulled into the nut and cannot be pulled out unless it is rotated away from the original hole. Rotate the tweezers back to the original nut boring position. The screws are shown in Figures 5, 6, and 7 as the side, back, and front views of the screw 109. They are similar to the general screws but have no threads, and a magnet 108 is attached to the bottom and the back view. The side view shows a prominent scorpion.

The polarity and position of the screw magnets must be arranged so that the boring of the nut is aligned with the tweezer of the screw. The screws and nuts are placed on the side of the rafter and the boring hole. When inserting, the repulsion must be overcome to insert, but as long as the nut is rotated 180 degrees after insertion, the polarity of the magnet of the screw and the nut will be opposite to form a suction force, and the cavity at the bottom of the nut on the mechanism will clamp the screw to form a mechanism card. The double action of the magnetic and magnetic forces makes the screws and nuts not loose. In the same way, the screw and the nut can be placed on the side of the dice and the hole to achieve the same effect, or the long magnet 107 (108) is changed into two circular magnets. The same function can be achieved at both ends.

This mechanism, which is based on the principle of the same-sex reciprocal attraction of the cassette and the magnet, makes locking and disassembly quite simple and quick. This creation will be widely used in the group organization of assembled toys, and there is no distress that blurs the top surface of the screw, which is a major creation of the assembled toy industry.
