Description

Front Magnetic Bead Chain Jewelry Lock

technical field

The invention relates to a jewelry lock, in particular to a front magnetic bead chain jewelry lock. A clasp for beaded necklace jewelry with rows of pearls, jade, agate and crystal.

Background technique

Pearls, jade and other bead-shaped jewelry are jewelry loved by women from ancient times to the present, and they are an important family in the jewelry family. With the improvement of people's living standards, women's demand for jewelry products is also increasing, and the consumption demand for pearls, jade and other jewelry is also diversified, personalized and graded. In China, although the styles of these jewelry have been continuously introduced in recent years and their quality has been continuously improved, the locks of these jewelry are single in variety and outdated in style. It is not conducive to the improvement of the grade of Chinese jewelry. In the past, most of the clasps of bead chain jewelry are elastic clasps or spring clasps. This kind of clasp has a single style, lack of change in shape, asymmetrical clasp body shape, gradual decrease or even loss of elasticity, and occasional shrapnel breakage. And most of the lock products can only act on single or double bead chains, and cannot connect multiple rows of jewelry bead chains, and can not arbitrarily adjust the length of jewelry bead chains as required. In addition, some locks use exposed magnets to attract and close, and the exposed magnets directly contact the body, which will easily cause the magnets to rust, and is also harmful to health.

Contents of the invention

Aiming at the problems existing in the prior art, the present invention provides a front-mounted magnetic bead chain jewelry lock, which solves the problems of single structure, inconvenient opening and short service life of the lock in the prior art.

The present invention is achieved through the following technical solutions:

The front magnetic bead chain jewelry lock includes an upper button body and a lower button body. One end of the upper button body is provided with an upper hinge shaft ear for hinged connection, and the other end of the upper button body is provided with an upper magnet seat. The upper magnet is located in the upper magnet seat; one end of the lower button body is provided with the double ears of the lower hinge shaft for hinged connection, and the hinge shaft hinges the single ear of the upper hinge shaft and the double ears of the lower hinge shaft together. The other end is provided with a lower magnet seat opposite to the upper magnet seat, and the lower magnet is arranged in the lower magnet seat; the outer surfaces of the upper magnet and the lower magnet are respectively coated with an upper metal sheet and a lower metal sheet.

The upper and lower magnet seats are grooves, and the contact surfaces of the upper and lower metal sheets are respectively flush with the port surfaces of the upper and lower magnet seats.

The magnetic poles of the upper and lower magnets are different.

An annular cavity is formed between the upper and lower button bodies.

The end of the lower button body is provided with a wrench for easy opening.

The advantages and effects of the present invention are as follows:

1. The magnetic poles of the upper and lower magnets are different, so that the upper and lower buttons approach inwardly under the action of the magnetic force. When they are combined together, an annular cavity is formed between the upper and lower buttons, which can hold multiple rows of beads. Any part of the chain or jewelry chain, the length of the multi-row jewelry chain can be adjusted arbitrarily.

2. The upper and lower buckles do not need any link with the jewelry bead chain, they can be removed at will and separated from the jewelry bead chain, which overcomes the previous lock that can only be used in single or double bead chains.

3. The magnet surface of the upper and lower button body is covered with metal sheet, the metal sheet can seal the magnet in the button body, isolate the nickel plated material on the surface of the magnet (NdFeB) from harming the human body, and prevent the magnet from rusting. It can prevent the harm to the human body caused by the chemical glue brought by bonding the magnet with glue.

In addition, it has the advantages of novel and beautiful appearance structure, good integrity, and can carry out various changes and shapes on bead chain jewelry, which adds a new style to this type of jewelry, and has the advantages of firm connection, convenient opening and closing, and long service life. The shape and structure of the body can be made into any shape acceptable to this type of jewelry. And it can be matched with various grades of bead chain jewelry.

Example

As shown in Figures 1-4, the main section of the present invention and the structural schematic diagram after one end of the upper and lower button bodies 1 and 2 are hinged. The upper button body 1 and the lower button body 2 are made of metal materials such as gold, silver, copper, steel or alloys. One end of the upper button body 1 is a hinged end, and this end is provided with an upper hinge shaft single ear 9 with an upper hinge shaft hole 11, and the other opening and closing end of the upper button body 1 is provided with an upper magnet seat 5, and the upper magnet seat It is a groove, and the upper magnet 3 is placed in the upper magnet seat 5 and glued together with the upper magnet seat 5. The outer surface of the upper magnet 3 is covered with a metal sheet 13, and the outer end surface of the upper metal sheet 13 is connected to the upper magnet seat 5. The end face of the opening is flat, and the hinged end of the lower button body 2 is provided with lower hinge shaft ears 10, the lower hinge shaft double ears 10 match the upper hinge shaft single ear 9, and the hinge shaft 8 passes through the upper and lower hinge shaft holes 11, 12 Hinge one end of the upper and lower button bodies 1 and 2 together, the other end of the lower button body 2 is an opening and closing end, and this end is provided with a lower magnet seat corresponding to the upper magnet seat 5 of the upper button body 1 6. The lower magnet seat is a groove, and the lower magnet 4 is put into the lower magnet seat 6 and glued together. The outer surface of the lower magnet 4 covers the lower metal sheet 14, and the outer end surface of the lower metal sheet 14 is connected to the lower magnet seat 6. The end face of the opening is flat, and the end of the lower button body is provided with a wrench for easy opening; when the upper and lower button bodies 1 and 2 are relatively combined together, the end faces of the contact ends of the upper and lower magnet seats 3 and 4 are in contact with each other. That is, they are attracted together under the action of magnetic force, and at the same time, the space between the upper and lower buttons is closed into an annular cavity. Fig. 5 is an application example of the present invention applied to a necklace.

When the present invention is used, the upper and lower buckle bodies 1 and 2 are in an open state, the necklace is worn on the neck, a suitable position in the middle of the necklace is selected, and the two branches of the necklace are fixed in parallel in the annular cavities of the upper and lower buckle bodies 1 and 2 , put the upper button body 1 on the lower button body 2, and under the action of the magnet, the two cavities in the upper and lower button body 1 and 2 respectively lock the two branches of the necklace. Press the opening and closing ends of the upper and lower bodies 1 and 2 relatively, and the upper and lower buckles 1 and 2 will be closed due to the magnetic force. When you want to untie the necklace, hold the upper buckle 1 with one hand and open the lower buckle with the other hand Push the wrench 7 on the 2 to the opening direction, and the upper and lower button bodies will be opened.
