As an embodiment, as shown in fig. 1 to 16, a button-type magnetic watch buckle includes: the first buckle 100 and the second buckle 200 are buckled with each other.

As shown in fig. 1-3, the first watch buckle 100 is provided with a key 120, and the second watch buckle 200 is provided with a fastening position capable of fastening and fixing the key 120. In the locked state, as shown in fig. 3, the key 120 and the snap-fit feature may provide a horizontal in-plane limit to the clasp.

As shown in fig. 1, 2 and 4, the adjacent stepped surfaces of the first buckle 100 and the second buckle 200 have matching engaging structures, that is, a matching first protrusion 310 and a first limiting groove 320, and a matching second protrusion 410 and a second limiting groove 420. In the locked state, as shown in fig. 4, the snap structure consisting of the protrusion and the retaining groove can provide a vertical in-plane retention for the buckle.

The button 120, the engaging portion and the engaging structure cooperate to lock the buckle. When an external force is applied in the locked state of the watch buckle, the force is dispersed to the key 120 and the engaging structure. So far, it can be understood by those skilled in the art that the engaging structure is actually the key point of the patent. After the acting force is dispersed to the block structure, the stress of the key 120 can be reduced, the deformation and damage of the key 120 caused by the overlarge instantaneous stress of the watch buckle are avoided, and the strength of the watch buckle is improved. The horizontal plane and the vertical plane are directions in the drawing, and do not refer to the horizontal direction and the vertical direction in the actual environment in the use process; the horizontal plane and the vertical plane are relative references only, and the force applied by the key 120 and the force applied by the snap structure do not have to be perpendicular to each other.

The first clasp 100 also has a first engaging member 110 therein, and the second clasp 200 also has a second engaging member 210 therein. The first engaging member 110 and the second engaging member 210 can be engaged with each other.

The first engaging member 110 and the second engaging member 210 may be both magnets, or one may be a magnet and the other may be made of a ferromagnetic material, as long as the two can be engaged and fixed with each other.

When the watch buckle needs to be fastened, the two watch buckles are firstly close to each other until the distance between the two watch buckles is small enough. Under the attraction of the first attraction part 110 and the second attraction part 210, the two surface fasteners are aligned with each other and further approach to each other to be fastened with each other. After the two surface fasteners are fastened, the key 120 is clamped and fixed in the clamping groove 220, the first protrusion 310 on the stepped surface is clamped and fixed with the first limiting groove 320, and the second protrusion 410 is clamped and fixed with the second limiting groove 420, so that the surface fasteners are locked and in a locked state.

When the watch buckle needs to be opened, the key 120 is pressed to move the key 120 upwards, so that the key 120 is separated from the clamping position upwards, and the watch buckle is in an unlocking state. In the unlocked state, the two watchbuttons still keep clamped and fixed in the vertical direction, but a user can pull the watchbuttons in the horizontal direction to separate the watchbuttons from each other.

In the operation process, referring to fig. 5, when the watch buckle is locked, the watch buckle can be opened by pulling the button 120 to the upper left. The locking and unlocking operation of the watch buckle is simple, and the use experience of a user is convenient to improve.

As shown in fig. 14 to 16, the key 120 includes a push portion 121, a slide portion 122, and a catch portion 123, which are connected at one time. The sliding portion 122 is located inside the first clasp 100 and is used for limiting the moving range of the key 120. The pushing portion 121 is connected to the outer side of the sliding portion 122, the pushing portion 121 extends to the outside of the first watch buckle 100, the size of the pushing portion 121 is increased to form a flat plate shape, which is beneficial to increasing the contact area between the hand of the user and the pushing portion 121, and is convenient for the user to operate.

The engaging portion 123 is located inside the sliding portion 122, as shown in fig. 3, 5, 8, and 9, the engaging portion 123 extends toward the second buckle 200, and a through hole for passing the engaging portion 123 is opened on the surface of the first buckle 100 facing the second buckle 200. The second buckle 200 is engaged with the second buckle 200 by a matching engaging slot 220, and the engaging slot 220 can be engaged with and fixed to the end of the engaging portion 123 facing the second buckle 200.

The main body of the key 120 is integrated inside the first watch buckle 100, which is beneficial to reducing the overall volume of the watch buckle. The clamping groove 220 is used as a clamping position, so that the structure is simple, and the production cost is reduced.

As shown in fig. 1, 2, 5-9 and 14, the number of the buttons 120 is two, two buttons 120 are located on two opposite sides of the two watchbuttons, and the first absorbing member 110 is located between the two buttons 120. The user can use two fingers to act on the key 120 from two sides of the watch buckle, the operation is convenient, and the watch buckle can be conveniently unlocked by the user. After the keys 120 are stressed, the resultant force of the forces of the two keys 120 on the first clasp 100 is located at almost the middle of the first absorbing element 110, which facilitates the clasp to open against the attractive forces of the first and second

absorbing elements

110 and 210.

As shown in fig. 3 and 14, the first clasp 100 is internally provided with a spring as an elastic member 130. One end of the elastic element 130 is fixed to the inner surface of the first watch buckle 100, and the other end is fixed to a surface of the sliding portion 122 facing away from the second watch buckle 200. The elastic member 130 exerts an acting force on the buckle in a direction toward the second buckle 200, so that the engaging portion 123 is kept inserted into the slot 220 and abuts against the inner wall of the slot 220 in the locked state.

In a preferred embodiment, as shown in fig. 4-13, first clasp 100 and second clasp 200 each have a first step surface 300 and a second step surface 400. In the locked state, the first step surface 300 of the first buckle 100 abuts against the first step surface 300 of the second buckle 200, and the second step surface 400 of the first buckle 100 abuts against the second step surface 400 of the second buckle 200.

In this embodiment, the first step surface 300 and the second step surface 400 of the first surface fastener 100 have a first protrusion 310 and a second protrusion 410, respectively, and the first step surface 300 and the second step surface 400 of the second surface fastener 200 are recessed to form a first stopper groove 320 and a second stopper groove 420. The first protrusion 310 may be inserted into the first groove 320, and the second protrusion 410 may be inserted into the second groove 420.

The outer surface of the first protrusion 310 may abut against the inner wall of the first limiting groove 320, and the outer surface of the second protrusion 410 may abut against the inner wall of the first limiting groove 320, so as to provide a limiting effect for the buckle.

When the watch buckle receives the acting force in the direction that the convex part is inserted into the limiting groove, one side surface of the convex part corresponding to the acting force direction is abutted against the limiting groove so as to disperse the force applied to the key 120. The first convex part 310 and the second convex part 410 have larger volume, can bear larger stress, effectively improve the surface fastener strength and prolong the surface fastener service life.

In practical production, the first step surface 300 and the second step surface 400 of the first buckle 100 can be provided with a limiting groove, and the first step surface 300 and the second step surface 400 of the second buckle 200 can be provided with a convex part; a limiting groove may be formed on one of the first step surface 300 and the second step surface 400 of the first surface fastener 100, a convex portion may be formed on the other, and a corresponding limiting groove and a corresponding convex portion may be formed on the second step surface 400 of the second surface fastener 200; can also set up convex part and spacing groove simultaneously on arbitrary ladder face, and the scheme after the adjustment all is in the protection of this patent.

In a preferred embodiment, as shown in fig. 1, 3 and 4, the first step surface 300 and the second step surface 400 are both inclined surfaces facing the second surface fastener 200 from the first surface fastener 100.

As shown in fig. 4, when the first buckle 100 is subjected to a horizontal force, the first step surface 300 and the second step surface 400 abut against each other. There is a tendency of relative slippage between the first step surface 300 and the second step surface 400, that is, the first buckle 100 tends to move to the upper right, and the second buckle 200 tends to move to the lower right. Therefore, the upper surface of the first protrusion 310 abuts against the upper inner surface of the first retaining groove 320 to disperse a portion of the stress between the two surface-engaging first step surfaces 300, and the lower surface of the second protrusion 410 abuts against the lower inner surface of the second retaining groove 420 to disperse a portion of the stress between the two surface-engaging second step surfaces 400. The strength of the first step surface 300 and the second step surface 400 of the two surface fasteners can be improved to prolong the service life of the surface fasteners.

In a preferred embodiment, as shown in fig. 6-8 and 10, 11, the first and second retaining

grooves

320, 420 are each trapezoidal in configuration, and the first and

second projections

310, 410 are each trapezoidal in configuration. And the short side of the trapezoid structure is close to one side of the first watch buckle 100, and the long side of the trapezoid structure is close to one side of the second watch buckle 200.

Referring to fig. 4, when the first buckle 100 is acted upward, the upper surface of the first protrusion 310 abuts against the inner surface of the upper side of the first limiting groove 320 to provide a limit, and the upper surface of the second protrusion 410 abuts against the side surface of the upper surface of the second limiting groove 420 to provide a limit.

As can be seen from fig. 5, when the first buckle 100 is subjected to an upward acting force, the two side surfaces of the first protrusion 310 and the second protrusion 410 also abut against the two side inner surfaces of the corresponding limiting grooves at the same time to limit the buckle, so that the stress on the protrusions is dispersed, which is beneficial to improving the strength of the first protrusion 310 and the second protrusion 410, thereby prolonging the overall life of the buckle.

In a preferred embodiment, as shown in fig. 14-16, one end of the engaging portion 123 forms a second plane 124, and the end of the engaging portion 123 is a circular arc surface. As shown in fig. 8, the second flat surface 124 is located on the side of the engaging portion 123 close to the second step surface 400.

Correspondingly, as shown in fig. 10-12, the slot 220 is D-shaped, and the vertical edge of the slot is used for abutting against the second plane 124 to limit the position of the key 120.

As shown in fig. 3, after the second plane 124 is provided, in a state that the watch buckle is locked, if the first watch buckle 100 is pulled from right to left, the second plane 124 is tightly abutted to the groove wall of the slot 220; if the first buckle 100 is pushed from left to right, the stepped surfaces of the first buckle 100 and the second buckle 200 are tightly abutted, so that the buckle is locked in the horizontal direction. In actual production, a first plane can be correspondingly arranged on one side of the clamping part facing the first stepped surface, so that the key bears the stress on a part of the stepped surface; in practical production, only the first step surface can be provided, and the above solutions are all within the protection scope of this patent.

When the first buckle 100 and the second buckle 200 are not completely buckled, referring to fig. 3, for example, when the end of the engaging portion 123 abuts against the second step surface 400 of the second buckle 200 while the first buckle 100 is moving from left to right, since the corresponding portion of the engaging portion 123 is an arc surface, the action of the second step surface 400 on the engaging portion 123 will generate an action effect of moving the key 120 upward. Therefore, when the first buckle 100 approaches the second buckle 200, the second buckle 200 acts on the engaging portion 123, and the button 120 moves upward against the elastic member 130, so that the first buckle 100 and the second buckle 200 can be smoothly buckled.

After the first buckle 100 and the second buckle 200 are fastened, the elastic element 130 exerts an elastic force on the key 120, so that the engaging portion 123 extends downward into the engaging slot 220 and is engaged and fixed with the engaging slot 220. Therefore, the first watch buckle 100 and the second watch buckle 200 can be automatically locked, and the clamping feeling due to the clamping part 123 is not generated in the buckling process, so that the use experience of a user is improved.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
