Description

Technical Field

[0001] This utility model relates to the field of fasteners, specifically a self-locking magnetic fastener. Background Technology

[0002] With the development of technology, magnetic buckles are frequently used in outdoor products such as bags, safety gear, and travel bags. Existing magnetic buckles have magnetic forces that are too strong or too weak, which can affect their performance. To facilitate the opening and closing of the buckles, the magnetic force is not set too high. However, when the magnetic force is insufficient, existing buckles (as shown in patent CN201920703472.1) may fail if there is lateral displacement between the male and female buckles. In this case, the hook will fail, and the buckle will easily separate due to the vertical force, which will greatly affect the buckle's fastening stability. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a self-locking magnetic fastener that makes it easier for users to fasten and unfasten the fastener, and provides good stability when fastening.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A self-locking magnetic fastener includes an upper main component, a lower main component, and a slider. A lower magnet is fixedly mounted on the lower main component, and an upper magnet is fixedly mounted on the slider. The slider is slidably inserted into the upper main component. A first slot, a second slot, and a hook are formed on the lower main component, and a first block and a second block are formed on the upper main component. When the fastener is engaged, the upper magnet and the lower magnet attract each other, the first block is embedded in the first slot, the second block is embedded in the second slot, the hook engages with the slider, and a sliding cover is provided on the slider. The sliding cover and the slider are fixedly connected, and the sliding cover is slidably mounted on the upper main component.

[0005] Furthermore, a sliding cavity is formed inside the upper main component, and a sliding groove is formed on the side wall of the sliding cavity; a sliding strip is formed on the side wall of the slider, the slider is slidably installed in the sliding cavity, and the sliding strip is inserted into the sliding groove.

[0006] Furthermore, a relief groove is formed on the slide bar. When the fastener is engaged, the hook passes through the relief groove and hooks onto the upper wall of the slide bar.

[0007] Furthermore, a limiting groove is formed on the upper main component, and a limiting strip is formed on the sliding cover. The length of the limiting strip is less than the length of the limiting groove; the limiting strip can be slidably inserted into the limiting groove.

[0008] Furthermore, the slider has a plurality of fixing holes, and the sliding cover has fixing posts that match the number of fixing holes, the fixing posts being fixedly inserted into the fixing holes.

[0009] Furthermore, the slider and the sliding cover are integrally formed.

[0010] Furthermore, the slider has a rope hole for attaching a pull rope.

[0011] Furthermore, a guide block is formed on the lower wall of the slider, and an upper inclined surface is formed on the guide block; a lower inclined surface is formed on the hook; when the fastener needs to be separated, the upper inclined surface and the lower inclined surface slide and abut against each other.

[0012] Furthermore, an upper cavity is formed on the slider, and the upper magnet is fixedly installed in the upper cavity; a lower cavity is formed on the lower main component, and the lower magnet is fixedly installed in the lower cavity.

[0013] Furthermore, the upper main component has an upper hole, and the lower main component has a lower hole.

[0014] By adopting the above-described technical solution of this utility model, at least the following beneficial effects are achieved: 1. When the fastener is engaged, the upper magnet and the lower magnet are automatically attracted to each other due to magnetic force, and the slider is automatically engaged and locked with the hook under the action of the upper magnet. The first locking block is embedded in the first locking groove, and the second locking block is embedded in the second locking groove, thus restricting the relative horizontal displacement of the upper and lower main components. At this time, the hook is engaged with the slider, thus restricting the relative vertical displacement between the upper and lower main components, greatly improving the stability of the fastener when engaged. When the fastener needs to be disengaged, an external force is applied to slide the slider. At this time, the upper magnet and the lower magnet are offset from each other by a certain distance in the horizontal direction, so that the hook and the slider disengage. In this way, the upper and lower main components can move relative to each other in the vertical direction until they are completely separated.

[0015] Second, the sliding engagement of the slide bar and the slide groove allows the slider to slide more smoothly within the slide cavity, greatly facilitating the fastening and disengagement of the fastener.

[0016] Third, the sliding cover and the slider are fixedly connected, and the length of the limiting strip is less than the length of the limiting groove, so that the range of motion of the slider is restricted, preventing the slider from falling out of the sliding cavity and further improving the stability of the fastener.

[0017] Compared with the prior art, this utility model uses a self-locking magnetic fastener, which can automatically lock through magnetic attraction when the fastener is engaged, and restricts the horizontal and vertical movement between the upper main component and the lower main component, so that the fastener has good stability when engaged.

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see the appendix Figures 1 to 6As shown, this utility model provides a self-locking magnetic fastener, including an upper main component 1, a lower main component 2, and a slider 3; a lower magnet 6 is fixedly installed on the lower main component 2, and an upper magnet 5 is fixedly installed on the slider 3; the slider 3 can be horizontally slidably inserted into the upper main component 1; a first slot 21, a second slot 22, and a hook 23 are respectively formed on the lower main component 2, and a first block 11 and a second block 12 are respectively formed on the upper main component 1; when the fastener is engaged, the upper main component 1 and the lower main component 2 are fitted together, the upper magnet 5 and the lower magnet 6 attract each other, the first block 11 is embedded in the first slot 21, the second block 12 is embedded in the second slot 22, the hook 23 is engaged with the slider 3, and a sliding cover 4 is provided on the slider 3, the sliding cover 4 is fixedly connected to the slider 3, and the sliding cover 4 can be slidably covered on the upper main component 1. When the fastener is engaged, the upper magnet 5 and the lower magnet 6 are automatically attracted to each other due to magnetic force, and the slider 3 is automatically engaged and locked with the hook 23 under the action of the upper magnet 5. The first locking block 11 is embedded in the first locking groove 21, and the second locking block 12 is embedded in the second locking groove 22, thus restricting the relative horizontal displacement of the upper main component 1 and the lower main component 2. At this time, the hook 23 is on the slider 3, which restricts the relative vertical displacement between the upper main component 1 and the lower main component 2, greatly improving the stability of the fastener when engaged. When the fastener needs to be disengaged, an external force is applied to slide the slider 3. At this time, the upper magnet 5 and the lower magnet 6 are offset from each other by a certain distance in the horizontal direction, so that the hook 23 and the slider 3 disengage. In this way, the upper main component 1 and the lower main component 2 can move relative to each other in the vertical direction until they are completely separated.

[0022] Preferably, a sliding cavity 13 is formed within the upper main component 1, and a sliding groove 14 is formed on the side wall of the sliding cavity 13; a sliding strip 31 is formed on the side wall of the slider 3, and the slider 3 is slidably mounted within the sliding cavity 13, with the sliding strip 31 inserted into the sliding groove 14. Through the sliding engagement of the sliding strip 31 and the sliding groove 14, the slider 3 can slide more smoothly within the sliding cavity 13, greatly facilitating the fastening and disengagement of the fastener.

[0023] Preferably, a relief groove 32 is formed on the slide bar 31. When the fastener is engaged, the hook 23 passes through the relief groove 32 and hooks onto the upper wall of the slide bar 31. This restricts the vertical movement between the upper main component 1 and the lower main component 2.

[0024] Preferably, such as Figure 4 and Figure 5As shown, a limiting groove 15 is formed on the upper main component 1, and a limiting strip 41 is formed on the sliding cover 4. The length of the limiting strip 41 is less than the length of the limiting groove 15; the limiting strip 41 is slidably inserted into the limiting groove 15. The sliding cover 4 and the slider 3 are fixedly connected. The length of the limiting strip 41 is less than the length of the limiting groove 15, thus restricting the range of motion of the slider 3, preventing the slider 3 from falling out of the sliding cavity 13, and further improving the stability of the fastener. Preferably, as shown... Figure 6 As shown, the slider 3 and the sliding cover 4 are integrally formed. Thus, the user only needs to slide the sliding cover 4 to move the slider 3, thereby disengaging the hook 23 from the slider 3. Preferably, the slider 3 has a plurality of fixing holes 33, and the sliding cover 4 has fixing posts 42 matching the number of fixing holes 33, the fixing posts 42 being fixedly inserted into the fixing holes 33.

[0025] Preferably, the slider 3 has a rope hole 35 for attaching a pull rope (not shown in the figure). This allows the user to move the slider 3 by pulling the pull rope.

[0026] Preferably, a guide block 36 is formed on the lower wall of the slider 3, and an upper inclined surface 37 is formed on the guide block 36; a lower inclined surface 24 is formed on the hook 23; when the fastener needs to be separated, the upper inclined surface 37 and the lower inclined surface 24 slide against each other. The sliding contact of the upper inclined surface 37 and the lower inclined surface 24 can raise the upper main component 1, which allows the first locking block 11 and the second locking block 12 on the upper main component 1 to gradually rise and disengage from the first locking groove 21 and the second locking groove 22 when the fastener is separated.

[0027] Preferably, the slider 3 has an upper cavity 34, and the upper magnet 5 is fixedly installed in the upper cavity 34; the lower main component 2 has a lower cavity 25, and the lower magnet 6 is fixedly installed in the lower cavity 25. When the upper magnet 5 and the lower magnet 6 are attracted and fixed, the fastener is in a fastened state, and the hook 23 is engaged with the upper wall of the slider 31.

[0028] Preferably, the upper main component 1 has an upper strap hole 16, and the lower main component 2 has a lower strap hole 26. The upper strap hole 16 and the lower strap hole 26 can be used to fix and install a shoulder strap or waist belt, etc.

[0029] Compared with the prior art, this utility model uses a self-locking magnetic fastener, which can automatically lock through magnetic attraction when the fastener is engaged, and restricts the horizontal and vertical movement between the upper main component 1 and the lower main component 2, so that the fastener has good stability when engaged.
