Description

The present invention relates to a clasp construction. Specifically, it relates to an automatic magnetic clasp and a method of using the automatic magnetic clasp.

Current clasps are attached by magnetic attraction with magnetic attraction components. However, the existing clasps do not have a rational design, so the clip holder and clip head are not connected securely. All existing clasps are designed to be flat and require two-handed operation when used, and can only be combined or separated at a single angle. Therefore, it is inconvenient to use. In addition, the existing clasp and clip holder cannot be rotated 360 degrees, so the clip holder and clasp cannot be conveniently combined or separated.

In order to solve the above problems, the present invention relates to an automatic magnetic clasp.
The invention also relates to the use of the automatic magnetic clasp described above.
The technical solutions adopted to achieve the above-mentioned object in the present invention are as follows.
It is an automatic magnetic clasp. The clasp consists of a clip head and a clip holder that fit together. The clip head has a clip head case. Cavite is installed in the clip head case penetrating both upper and lower ends of the clip head case. The cavite has a clasp component; the clip holder has a holder head which is combined with the clasp component. Magnetic attraction components that attract each other are installed on the clip head and the clip holder. The clip head and the clip holder are integrally attracted by a combination of magnetic attraction components. The clasp part and the holder head are combined to fix and connect the clip head and the clip holder.

The clasp components described above include left and right fasteners of the same construction that are symmetrically installed in the cavite. The middle of the left and right fasteners rocks and is hinged in the cavite. A compression spring is connected between the upper inner surfaces of the left and right fasteners. Blocks are installed below the left and right fasteners, facing each other and combined with the above holder head. A fastener spreader is connected above the left and right fasteners. By applying force to the fastener spreader, you can swing the left and right fasteners upside down, increasing the distance between the left and right fasteners and preventing the holder head from being pinched by the block. .. A force is applied to the clip head and the clip holder, and when the force is larger than the magnetic attraction force between the magnetic attraction components, the holder head and the clip holder can be separated.

The magnetic attraction component of the clip head is installed under the cavite. The underside of the clasp component is surrounded by the magnetically attractable component of the clip head. The magnetic attraction part of the clip holder is installed in the clip holder. The magnetic attraction part of the clip holder is located below the holder head. When the clip head and the magnetic attraction parts of the clip holder are attracted to each other, the holder head can be automatically inserted between both blocks. Since the compression spring is connected between the upper inner surfaces of the left and right fasteners, the holder head can be firmly sandwiched between both blocks.

The clip head case includes a front case and a rear case to be combined. On the opposite wall surfaces of the front case and the rear case, there are installed the mid recesses that form the above cavities.

A metal piece is fixed between the upper side of the front case and the upper side of the rear case. A ring protruding from the top parts of the front case and the rear case is installed on the upper side of the metal piece. When using it, put the string through the ring and then hang it firmly to complete the fixing and connection of the string and clip head case.

The fastener spreading device is a rope; both ends of the rope are secured to the upper side of the left and right fasteners, respectively. The middle part of the rope passes through the clip head case from the top part of the cavitate above. If you need to separate the clip holder and clip head, pull the rope up and rock the tops of the left and right fasteners face-to-face so that the distance between the two blocks increases so that you can pull out the holder head. It was

The fastener spreader described above is two fasteners; the fasteners include a restraining rod and a restraining head that are connected to each other. The retaining rods of the two retaining brackets contact the outer surfaces of the left and right fasteners, respectively. The holding head extends the outer peripheral surface of the clip head case.

The above blocks are installed sideways. At the end of the block there is a triangular or semi-circular crevice; the holder head is a mushroom-shaped protrusion that mates with the block. The mushroom-shaped protrusion is composed of a lower pillar and an upper union body, like a mushroom. The diameter of the union body is larger than the diameter of the column. Both blocks above hang on the pillar. Both blocks are below the union body.

The clip holder is plate-shaped. Strip-shaped slots are installed at both ends of the clip holder. Two strip-shaped slots are installed in parallel. In use, another string is threaded through the two strip-shaped slots in sequence to make the connection between the clip holder and the string more firm and stable.

The clip holder has a slot shape. A strip-shaped slot is installed on the bottom of the clip holder. The strip-shaped slots are installed in parallel. When used, another string is threaded through the strip-shaped slots sequentially to make the connection between the clip holder and the string more firm and stable.

There is a circular recess on the upper surface of the clip holder; the inner diameter of the circular recess is larger than the outer diameter of the clip head case. The holder head is in the middle of the circular recess. Thanks to the circular recess, the connection between the clip head and the clip holder is prevented from being impacted by external force, and the connection is made firmer and more stable.

The above clip holder has a cylindrical shape. There is a metal fitting under the clip holder. A strip-shaped slot is installed in the metal fitting.

There is a circular recess on the upper surface of the clip holder; the inner diameter of the circular recess is larger than the outer diameter of the clip head case. The holder head is in the middle of the circular recess.
