[0002] A quick-release buckle is a device that can quickly connect and disassemble two components. It has the advantages of simple and fast operation, and can achieve the connection and separation of components in a short time. It is widely used in fields such as cameras and backpacks. The existing quick-release buckles use a mechanical locking mechanism to lock the quick-release plate and the main body. The blockers designed at the bottom of the chute of some quick-release buckles are too large. Even if the quick-release plate is not fully engaged, the lock tongue will still trigger a "click" sound, which is likely to cause users to misjudge that the quick-release plate has been installed in place. Secondly, it is difficult for users to intuitively judge the installation state of the quick-release buckle, and they need to shake it left and right additionally to confirm whether the installation is in place, which increases the operation complexity.

[0027] Embodiment 1:

[0028] In this embodiment, a magnetic quick-release buckle, as Figures 1 to 5 shown, includes a buckle base 1 and a quick-installation plate 2. Specifically, a chute 3 matching the quick-installation plate 2 is provided at the top of the buckle base 1. The chute 3 is horizontally arranged in the transverse direction. The quick-installation plate 2 can be inserted into the chute 3 from one end of the chute 3. A limiting groove 4 is provided at the bottom of the chute 3. An iron bar 5 is provided in the limiting groove 4. The iron bar 5 is sunk in the limiting groove 4. A magnetic block 6 is provided in the quick-installation plate 2. A card slot 7 is provided at the bottom of the quick-installation plate 2. The magnetic block 6 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 caught in the card slot 7. A button 8 communicating with the card slot 7 is provided at the top of the quick-installation plate 2. The button 8 is used to press the iron bar 5 when unlocking so that it returns to the limiting groove 4. When engaging, the quick-installation plate 2 is horizontally inserted into the chute 3, and the iron bar 5 is caught in the card slot 7 by the suction force of the magnetic block 6 to lock the buckle base and the quick-installation plate 2.

[0029] With this structure, when in use, the quick-installation plate 2 is inserted into the chute 3 of the buckle base 1. The magnetic force of the magnetic block 6 causes the iron bar 5 in the limiting groove 4 to move upward and be caught in the card slot 7 of the quick-installation plate 2, thereby firmly locking the quick-installation plate 2 and the buckle base 1. When unlocking, only need to press the button 8 to make the iron bar 5 return to its original position, and then translate the quick-installation plate 2 in the reverse direction. The structure is simple, the connection is reliable and does not come off by mistake, the unlocking is convenient and labor-saving, and it has broad application prospects.

[0030] As a specific implementation manner of this embodiment, as Figure 1 , Figure 3 and Figure 4 shown, the above-mentioned buckle base 1 is provided with a first side plate 9 and a second side plate 10. The above-mentioned first side plate 9 and the second side plate 10 are symmetrically arranged. The above-mentioned first side plate 9 and the second side plate 10 can be parallel to each other or inclined to each other. A chute 3 is formed between the first side plate 9, the second side plate 10 and the top surface of the above-mentioned buckle base 1. First slots 11 and second slots 12 are respectively provided on the inner walls of the first side plate 9 and the second side plate 10 facing each other. One end of the limiting slot 4 is communicated with the first slot 11, and the other end of the limiting slot 4 is communicated with the second slot 12 and penetrates through the second side plate 10. Both ends of the iron bar 5 extend into the first slot 11 and the second slot 12 respectively. The top ends of the first slot 11 and the second slot 12 are higher than the limiting slot 4. When the iron bar 5 is attracted by the magnet 6, the iron bar 5 moves upward. At this time, both ends of the iron bar 5 also move upward to the top ends 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, so as to lock the iron bar 5 both horizontally and vertically, and lock the quick installation plate 2 and the buckle base 1 firmly.

[0031] It should be noted that, as Figure 3 described, when the quick insertion plate is completely inserted into the buckle base 1, at this time, the card slot 7 at the bottom of the quick installation plate 2 just aligns with the limiting slot 4 on the buckle base 1. The iron bar 5 is attracted by the magnet 6 and moves upward and is stuck into the card slot 7. At this time, the iron bar 5 will lift the button 8 together. The user can intuitively see that the button 8 is pushed up, and then it can be confirmed that the quick installation plate 2 and the buckle base 1 are locked, without the need for secondary confirmation of whether the installation is in place.

[0032] In this embodiment, as Figure 3 described, the number of the above-mentioned magnets 6 is two. Embedding holes are provided on both sides of the quick installation plate 2. The magnets 6 are inserted into the embedding holes. The embedding holes are located at both ends above the card slot 7. When the buckle base 1 and the quick installation plate 2 are clamped in place, the magnet 6 is just located above the iron bar 5, so as to quickly attract the iron bar 5 to move upward and be stuck into the card slot 7.

[0033] In this embodiment, a plug 13 is further included. The plug 13 is detachably arranged in the second slot 12. During installation, first place the iron bar 5 into the limiting slot 4 through one end of the second side plate 10 penetrating through the limiting slot 4, and then use the plug 13 to block it to prevent the iron bar 5 from falling off from the limiting slot 4.

[0034] In this embodiment, asFigure 4 and Figure 5 As described above, one end of the sliding groove 3 is a narrow opening and the other end is a wide opening. The quick installation plate 2 is a trapezoidal plate matching the cross-sectional shape of the sliding groove 3, so that the edge of the quick installation plate 2 can be completely attached to the groove wall of the sliding groove 3. At this time, the quick installation plate 2 reaches the final position of being inserted into the sliding groove 3, that is, the installation is in place. At this time, the limiting groove 4 and the clamping groove 7 are vertically aligned, and the iron bar 5 can move upward under the magnetic force and be clamped into the clamping groove 7.

[0035] Furthermore, as Figure 4 shown, in order to strengthen the position constraint of the quick installation plate 2, the top parts of the opposite 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 near one end of the narrow opening of the sliding groove 3. The first upper baffle 14 and the second upper baffle 15 limit the quick installation plate 2 vertically, so that the quick installation plate 2 has no freedom in the vertical direction and cannot move up and down. One end of the first limiting plate 16 and the second limiting plate 17 limits the quick installation plate 2 horizontally. Cooperating with the clamping limit of the iron bar 5 and the clamping groove 7, the quick installation plate 2 has no freedom in the horizontal direction and cannot move horizontally left and right, thereby firmly locking the quick installation plate 2 and the buckle seat 1.

[0036] In this embodiment, as Figure 1 shown, a connection hole 18 is provided at one end of the buckle seat 1 away from the narrow opening of the sliding groove 3, and a connection rope 19 is provided at one end of the quick installation plate 2 close to the narrow opening of the sliding groove 3. The connection hole 18 and the connection rope 19 are respectively connected to two objects, so that the two objects can be firmly connected through the quick disassembly cooperation between the buckle seat 1 and the quick installation plate 2.

[0037] According to a preferred embodiment, as Figure 5 shown, the quick installation plate 2 is provided with a through hole 24 communicating with the clamping groove 7, and the button 8 is movably inserted into the through hole 24. When the buckle seat 1 and the quick installation plate 2 are clamped, the iron bar 5 pushes up the button 8, so that the button 8 moves upward along the through hole 24 and protrudes from the top surface of the quick installation plate 2.

[0038] As an optimization, as Figure 3As shown, upper retaining discs 20 and lower retaining discs 21 are respectively provided at both ends of the above-mentioned button 8, upper sinking grooves 22 and lower sinking grooves 23 are respectively provided at both ends of the above-mentioned through hole 24. During snap connection, the above-mentioned button 8 moves upward so that the above-mentioned lower retaining disc 21 abuts against the inside of the above-mentioned lower sinking groove 23. During unlocking, the above-mentioned upper retaining disc 20 moves downward so that the above-mentioned upper retaining disc 20 abuts against the inside of the above-mentioned upper sinking groove 22. The above-mentioned upper retaining disc 20 and lower retaining disc 21 play a role in preventing dropping, preventing the above-mentioned button 8 from detaching from the above-mentioned quick-release plate 2. The above-mentioned lower retaining disc 21 is integrally formed with the above-mentioned button 8, and the above-mentioned upper retaining disc 20 can be connected to the above-mentioned button 8 by means of threads.

[0039] In this embodiment, both the above-mentioned buckle base 1 and the quick-release plate 2 are rigid plastic structural parts. When the above-mentioned buckle base 1 and the quick-release plate 2 are snap-connected, the above-mentioned iron bar 5 impacts on the above-mentioned quick-release plate 2 under the action of the above-mentioned magnet 6, and a clear knocking sound can be generated, which is beneficial for the user to immediately know that the installation is in place and the locking is completed. It has high structural strength and a long service life.

[0040] As described above, only the specific embodiments of the present invention are given, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
