Description

Technical Field

[0001] The utility model relates to an inverted magnetic watch strap buckle, and relates to the technical field of watch strap buckles. Background Art

[0002] When a watch is in use, it needs to be connected to the watch strap by a buckle. Traditional watch strap buckles are mostly snap-on connection structures, and the buckles between the watch strap buckles need to be aligned and pressed to connect, which is cumbersome to use.

[0003] In order to improve the convenience of using the watch strap buckle, a magnetic and snap-on structure is adopted in the prior art. For example, the patent technology with announcement number CN220212162U discloses a watch strap connection magnetic buckle, including a first buckle seat and a second buckle seat, the inner sides of the first buckle seat and the second buckle seat are both provided with a magnetic attraction mechanism, the first buckle seat includes a first main seat, a spring mounting groove is provided in the middle of the inner side of the first main seat, button mounting grooves are provided at both ends of the first main seat, and the button mounting groove is connected with both ends of the spring mounting groove, a snap button is slidably connected to the inner side of the button mounting groove, and a connecting buckle is integrally formed on one side of the snap button. A sliding column is installed on the inner side of the spring mounting groove; through the designed compression sleeve, sliding column and spring cylinder, the sliding column, connecting buckle and buckle button are pushed to slide by the elastic force of the main spring, so that the two sets of buckle buttons and connecting buckles support each other, and the spring cylinder is sleeved on the main spring and the compression sleeve. When in use, pinching the buckle button is more stable, ensuring the travel of the buckle button and the connecting buckle, thereby effectively driving the connecting buckle to move for switching. However, the structure is more complicated and still needs to be connected through the buckle. If the buckle is not clamped or the spring effect is not good, it will affect the fastening effect, and it only achieves magnetic attraction through two smaller magnetic buttons, and the magnetic attraction effect is relatively poor.

[0004] The purpose of the utility model is to provide an inverted magnetic watchband buckle to address the defects or shortcomings in the prior art. By setting an arc-shaped watchband buckle as the main body of the magnetic buckle, the large-area magnet adsorption effect is better, and an anti-drop inverted buckle is provided on the watchband buckle to cooperate with the card slot.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes an upper connecting buckle 1 and a lower connecting buckle 2, the middle part of the upper connecting buckle 1 is an upper magnetic buckle body 11, and the middle part of the lower connecting buckle 2 is a lower magnetic buckle body 21, the upper connecting buckle 1 and the lower connecting buckle 2 are magnetically connected through the upper magnetic buckle body 11 and the lower magnetic buckle body 21, and a first upper anti-detachment inverted buckle 13 and a second upper anti-detachment inverted buckle 14 are arranged on one side of the connecting surface between the upper magnetic buckle body 11 and the lower magnetic buckle body 21, and a first anti-detachment limiting groove 22 and a second anti-detachment limiting groove 23 are arranged on the magnetic buckle body 21, which respectively cooperate with the first upper anti-detachment inverted buckle 13 and the second upper anti-detachment inverted buckle 14.

[0010] Furthermore, the bottom of the upper connecting buckle 1 is a pull ear 12.

[0011] Furthermore, a first strap connecting shaft 3 is disposed at the top of the upper connecting buckle 1 , and a second strap connecting shaft 4 is disposed at the bottom of the lower connecting buckle 2 .

[0020] Explanation of the accompanying drawings: upper connecting buckle 1, lower connecting buckle 2, first watchband connecting axis 3, second watchband connecting axis 4, upper magnetic buckle body 11, pull ear 12, first upper anti-slip buckle 13, second upper anti-slip buckle 14, magnetic buckle body 21, first anti-slip limit groove 22, second anti-slip limit groove 23. DETAILED DESCRIPTION

[0021] See also Figure 1-Figure 5 As shown, the technical solution adopted in this specific embodiment is: it includes an upper connecting buckle 1 and a lower connecting buckle 2, the middle part of the upper connecting buckle 1 is an upper magnetic buckle body 11, and the middle part of the lower connecting buckle 2 is a lower magnetic buckle body 21. In this embodiment, the main body parts of the upper connecting buckle and the lower connecting buckle in the middle adopt strong magnets as the main body, that is, the upper magnetic buckle body and the lower magnetic buckle body. The facing surfaces of the strong magnets are opposite magnetic poles, which can be firmly adsorbed when in contact. Specifically, the upper connecting buckle 1 and the lower connecting buckle 2 are magnetically connected through the upper magnetic buckle body 11 and the lower magnetic buckle body 21;

[0022] More specifically, a first upper anti-slip inverted buckle 13 and a second upper anti-slip inverted buckle 14 are provided on one side of the connection surface between the upper magnetic buckle body 11 and the lower magnetic buckle body 21. The first upper anti-slip inverted buckle 13 and the second upper anti-slip inverted buckle 14 have the same structure and are symmetrically arranged on both sides of the upper magnetic buckle body 11. One side of the first upper anti-slip inverted buckle 13 and the second upper anti-slip inverted buckle 14 is a vertical surface in the axial direction and one side is an inclined surface. Since only magnetic connection is adopted in this embodiment, in order to prevent the upper connecting buckle from being separated from the lower connecting buckle due to the stretching of the watchband to both sides during wearing, two anti-slip inverted buckles are provided on both sides of the bottom of the upper magnetic buckle body, and the anti-slip inverted buckle has a vertical surface on one side and an inclined surface on the other side in the axial direction. The vertical surface is a constraint surface. Under the constraint of the lower connecting buckle, it cannot be separated when the upper and lower connecting buckles are pulled to both sides, thereby achieving an anti-slip effect.

[0023] Furthermore, the magnetic buckle body 21 is provided with a first anti-slip limit groove 22 and a second anti-slip limit groove 23 which respectively cooperate with the first upper anti-slip buckle 13 and the second upper anti-slip buckle 14. The shapes of the first anti-slip limit groove 22 and the second anti-slip limit groove 23 match the first upper anti-slip buckle 13 and the second upper anti-slip buckle 14. Similarly, the first anti-slip limit groove and the second anti-slip limit groove have a vertical surface on one side and an inclined surface on the other side axially. When the watch strap is pulled to both sides, the vertical surface of the anti-slip buckle is offset against the vertical surface of the anti-slip limit groove, and the anti-slip limit groove constrains the anti-slip buckle, thereby forming an anti-slip structure. The more it is stretched when worn, the better the fastening effect is.

[0024] To be more specific, the upper connecting buckle 1 and the lower connecting buckle 2 are arc-shaped structures. Traditional watch strap buckle structures are mostly flat structures. In this embodiment, they are designed as arc-shaped structures, which fit the wrist better and are more comfortable to wear.

[0025] More specifically, the bottom of the upper connecting buckle 1 is a pull ear 12, through which the upper connecting buckle can be pulled up more conveniently.

[0026] More specifically, a first watch strap connecting shaft 3 is disposed at the top of the upper connecting buckle 1, and a second watch strap connecting shaft 4 is disposed at the bottom of the lower connecting buckle 2, and the two connecting shafts are used to connect with the watch strap.

[0027] The working principle of the utility model is as follows: when in use, the arc surface of the upper connecting buckle 1 is placed above the arc surface of the lower connecting buckle 2, and the upper magnetic buckle body 11 is magnetically attracted to the lower magnetic buckle body 21, so that the upper connecting buckle 1 is accurately connected to the lower connecting buckle 2. At the same time, the first upper anti-slipping inverted buckle 13 and the second upper anti-slipping inverted buckle 14 are inserted into the first anti-slipping limiting groove 22 and the second anti-slipping limiting groove 23. Since one side of the first upper anti-slipping inverted buckle 13 and the second upper anti-slipping inverted buckle 14 is a vertical surface, which cooperates with the vertical surfaces of the first anti-slipping limiting groove 22 and the second anti-slipping limiting groove 23, when the watch strap is worn, it is stretched to both sides, and the two anti-slipping inverted buckles are constrained by the vertical surfaces of the two anti-slipping limiting grooves, so that the watch strap buckle cannot loosen and move when stretched.

[0028] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
