Description

Technical Field

[0001] This utility model belongs to the field of fastener technology, and specifically relates to a magnetic quick-release fastener. Background Technology

[0002] Quick-release buckles are devices that allow for the rapid connection and disconnection of two components. They are easy and quick to operate, enabling the connection and separation of components in a short time. They are widely used in fields such as cameras and backpacks. Existing quick-release buckles use mechanical locking mechanisms to lock the quick-release plate to the main body. Some quick-release buckles have excessively large stoppers at the bottom of the slide, causing the locking tongue to make a "click" sound even if the quick-release plate is not fully engaged, which can easily lead users to misjudge that the quick-release plate is installed correctly. Secondly, it is difficult for users to visually judge the installation status of the quick-release buckle, requiring additional confirmation by shaking it left and right, which increases the complexity of operation. Some quick-release buckles also require considerable force to remove the triangular ring, posing a risk of accidentally injuring fingernails.

[0003] Therefore, a magnetic quick-release buckle that locks securely without accidental release, is easier to install and remove, and saves effort is urgently needed. Utility Model Content

[0004] This utility model provides a magnetic quick-release buckle to solve the technical problems of insufficient firmness, difficulty in proper installation, and laborious disassembly of ordinary quick-release buckles in the prior art.

[0005] This utility model is achieved through the following technical solution: a magnetic quick-release buckle, including a buckle base and a quick-release plate. The top of the buckle base is provided with a sliding groove that matches the quick-release plate. The bottom of the sliding groove is provided with a limiting groove. An iron bar is provided in the limiting groove. A magnetic block is provided in the quick-release plate. A slot is provided at the bottom of the quick-release plate. A button communicating with the slot is provided at the top of the quick-release plate. When snapped in, the quick-release plate can be inserted horizontally into the sliding groove. The iron bar is snapped into the slot by the attraction of the magnetic block to lock the buckle base and the quick-release plate.

[0006] To better realize this utility model, further optimizations are made to the above structure. The buckle is provided with a first side plate and a second side plate, which are symmetrically arranged. The first side plate, the second side plate, and the top surface of the buckle form the sliding groove. The inner walls of the first side plate and the second side plate are respectively provided with a first slot and a second slot. One end of the limiting groove is connected to the first slot, and the other end of the limiting groove is connected to the second slot and passes through the second side plate. The two ends of the iron bar extend into the first slot and the second slot, respectively.

[0007] To better realize this utility model, the above structure is further optimized by including a plug, which is detachably disposed in the second slot.

[0008] To better realize this utility model, further optimizations are made to the above structure: one end of the slide is narrow and the other end is wide, and the quick-release plate is a trapezoidal plate that matches the cross-sectional shape of the slide.

[0009] To better realize this utility model, further optimizations are made to the above structure.

[0027] Example 1:

[0028] In this embodiment, a magnetic quick-release buckle is used, such as Figures 1 to 5 As shown, it includes a fastener 1 and a quick-release plate 2. Specifically, the fastener 1 has a groove 3 at its top that matches the quick-release plate 2. The groove 3 is horizontally arranged, and the quick-release plate 2 can be inserted into the groove 3 from one end. The bottom of the groove 3 has a limiting groove 4, and an iron bar 5 is placed in the limiting groove 4. The iron bar 5 is recessed in the limiting groove 4. The quick-release plate 2 has a magnetic block 6, and the bottom of the quick-release plate 2 has a locking groove 7. The quick-release plate 2 is used to attract the iron bar 5, so that the iron bar 5 can move upward under the action of magnetic attraction, and a part of the iron bar 5 is stuck into the slot 7. The top of the quick-release plate 2 is provided with a button 8 that communicates with the slot 7. The button 8 is used to press the iron bar 5 when unlocking, so that it returns to the limiting groove 4. When locking, the quick-release plate 2 is inserted horizontally into the sliding groove 3, and the iron bar 5 is locked into the slot 7 by the attraction of the magnetic block 6 to lock the buckle and the quick-release plate 2.

[0029] With this structure, when in use, the quick-release plate 2 is inserted into the sliding groove 3 of the buckle 1. The magnetic force of the magnetic block 6 causes the iron bar 5 in the limiting groove 4 to move upward and get stuck in the slot 7 of the quick-release plate 2, thereby firmly locking the quick-release plate 2 and the buckle 1. When unlocking, simply press the button 8 to return the iron bar 5 to its original position, and then move the quick-release plate 2 in the opposite direction. The structure is simple, the connection is reliable and will not accidentally come off, and the unlocking is convenient and labor-saving, with broad application prospects.

[0030] As one specific implementation method of this embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the buckle 1 has a first side plate 9 and a second side plate 10, which are symmetrically arranged. The first side plate 9 and the second side plate 10 can be parallel to each other or inclined to each other. The first side plate 9, the second side plate 10, and the top surface of the buckle 1 form the sliding groove 3. The inner walls of the first side plate 9 and the second side plate 10 are respectively provided with a first slot 11 and a second slot 12. One end of the limiting groove 4 communicates with the first slot 11, and the other end of the limiting groove 4 communicates with the second slot 12 and passes through the second side plate 10. The two ends of the strip 5 extend into the first slot 11 and the second slot 12 respectively. The top of the first slot 11 and the second slot 12 is higher than the limiting groove 4. When the iron strip 5 is attracted by the magnetic block 6, the iron strip 5 moves upward. At this time, the two ends of the iron strip 5 also move upward to the top of the first slot 11 and the second slot 12, and are then limited by the top walls of the first slot 11 and the second slot 12, and only abut against the top walls of the first slot 11 and the second slot 12, thereby locking the iron strip 5 in both the horizontal and vertical directions, so that the quick-release plate 2 and the buckle 1 are firmly locked.

[0031] It is worth noting that, such as Figure 3 As described above, when the quick-release plate is fully inserted into the buckle 1, the slot 7 at the bottom of the quick-release plate 2 is aligned with the limiting slot 4 on the buckle 1. The iron bar 5 is attracted by the magnetic block 6 and moves upward and is inserted into the slot 7. At this time, the iron bar 5 will lift the button 8 together. The user can see the button 8 being lifted up, and can confirm that the quick-release plate 2 and the buckle 1 are locked together without the need for secondary confirmation of whether the installation is in place.

[0032] In this embodiment, as Figure 3 The number of magnetic blocks 6 is two. The quick-release plate 2 has recessed holes on both sides. The magnetic blocks 6 are inserted into the recessed holes. The recessed holes are located at both ends above the slot 7. When the buckle 1 and the quick-release plate 2 are engaged, the magnetic blocks 6 are just above the iron bar 5, so that the iron bar 5 can be quickly attracted, moved upward and engaged in the slot 7.

[0033] In this embodiment, a plug 13 is also included. The plug 13 is detachably disposed in the second slot 12. During installation, the iron bar 5 is first inserted into the second side plate 10 through the limiting groove 4 and then the plug 13 is used to seal it to prevent the iron bar 5 from falling out of the limiting groove 4.

[0034] In this embodiment, as Figure 4 and Figure 5 The aforementioned slide groove 3 has a narrow opening at one end and a wide opening at the other end. The quick-release plate 2 is a trapezoidal plate that matches the cross-sectional shape of the slide groove 3, so that the edge of the quick-release plate 2 can completely fit against the groove wall of the slide groove 3. At this time, the quick-release plate 2 reaches the final position of being inserted into the slide groove 3, that is, it is installed in place. At this time, the limiting groove 4 and the locking groove 7 are aligned vertically, and the iron strip 5 can move upward and be locked into the locking groove 7 under the action of magnetic force.

[0035] Furthermore, such as Figure 4 As shown, in order to strengthen the positional constraint of the quick-release plate 2, the top of the inner walls of the first side plate 9 and the second side plate 10 are respectively provided with a first upper baffle 14 and a second upper baffle 15. The first side plate 9 and the second side plate 10 are respectively provided with a first limiting plate 16 and a second limiting plate 17 at the end near the narrow opening of the slide groove 3. The first upper baffle 14 and the second upper baffle 15 limit the quick-release plate 2 in the vertical direction, so that the quick-release plate 2 has no freedom in the vertical direction and cannot move up and down. The first limiting plate 16 and the second limiting plate 17 limit the quick-release plate 2 at one end in the horizontal direction. With the engagement and limiting of the iron bar 5 and the slot 7, the quick-release plate 2 has no freedom in the horizontal direction and cannot move left and right, thereby firmly locking the quick-release plate 2 and the buckle 1.

[0036] In this embodiment, as Figure 1 As shown, the buckle 1 is provided with a connecting hole 18 at the end away from the narrow opening of the slide groove 3, and the quick-release plate 2 is provided with a connecting rope 19 at the end near the narrow opening of the slide groove 3. The connecting hole 18 and the connecting rope 19 connect two objects respectively, so that the two objects can be firmly connected by the quick-release engagement of the buckle 1 and the quick-release plate 2.

[0037] According to a preferred embodiment, such as Figure 5 As shown, the quick-release plate 2 is provided with a through hole 24 that communicates with the slot 7. The button 8 is movably inserted into the through hole 24. When the buckle 1 and the quick-release plate 2 are engaged, the iron bar 5 pushes the button 8 up, causing the button 8 to move upward along the through hole 24 and protrude from the top surface of the quick-release plate 2.

[0038] As an optimization, such as Figure 3As shown, the button 8 has an upper baffle 20 and a lower baffle 21 at both ends, and the through hole 24 has an upper recess 22 and a lower recess 23 at both ends. When engaged, the button 8 moves upward so that the lower baffle 21 abuts against the lower recess 23. When disengaged, the upper baffle 20 moves downward so that the upper baffle 20 abuts against the upper recess 22. The upper baffle 20 and the lower baffle 21 serve to prevent the button 8 from falling off the quick-release plate 2. The lower baffle 21 is integrally formed with the button 8, and the upper baffle 20 can be threaded onto the button 8.

[0039] In this embodiment, both the buckle 1 and the quick-release plate 2 are rigid plastic structural parts. When the buckle 1 and the quick-release plate 2 are engaged, the iron strip 5 strikes the quick-release plate 2 under the action of the magnetic block 6, which can produce a crisp knocking sound. This helps the user to immediately know that the installation is in place and the locking is complete. The structure has high strength and long service life.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
