Technical Field

[0001] This utility model belongs to the field of connection structure technology, and in particular relates to a quick-release buckle. Background Technology

[0002] When using photography equipment outdoors, people typically attach it to their body via the shoulder straps of a backpack for easy access. Most photography equipment is secured to the shoulder strap using quick-release buckles. Chinese patent CN119184422A discloses a "Magnetic Quick-Release Buckle," which includes a buckle base, a buckle member, and a button. The button includes a locking tongue, a pressing part, and an elastic part. In the locked state, the locking tongue is adjacent to the buckle member and restricts its vertical movement. In the unlocked state, the locking tongue separates from the buckle member, and the buckle member moves vertically towards the wide end of the V-shaped slot under magnetic force. However, its structure is relatively complex, and it may malfunction if the pressing part deforms. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a quick-release buckle, which enables the quick installation and disassembly of the fastener and the buckle seat, and the connection is stable after installation.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a quick-release buckle, comprising:

[0005] A fastener includes at least a body and a movable part that is movably connected to the body;

[0006] The fastener has a first window for the fastener to extend into and a second window for engaging the fastener.

[0007] A magnetic unit, located on the fastener, or on the fastener and fastener base, is used to drive the moving body to move away from the main body.

[0008] The fastener can switch between the first window and the second window under the action of external force. When the fastener enters the second window, the movable body moves away from the main body so that the fastener and the fastener seat are snapped together, and part of the movable body extends out of the second window.

[0009] Furthermore, the magnetic unit is disposed on the fastener, and includes a first magnet connected to the body and a second magnet connected to the movable body, wherein the first magnet and the second magnet repel each other.

[0010] Furthermore, the magnetic unit is disposed on the fastener and the fastener base, and includes a third magnet disposed on the fastener and a fourth magnet disposed on the fastener base corresponding to the second window, wherein the third magnet and the fourth magnet repel each other.

[0011] Furthermore, the buckle seat is provided with an adsorption element for attracting the buckle at the position corresponding to the first window.

[0012] Furthermore, the adsorption element is an iron sheet or a magnet.

[0013] Furthermore, the body forms a first groove for accommodating a first magnet, the sidewalls and bottom wall of the first groove covering the outer peripheral surface and first magnetic pole of the first magnet, and the second magnetic pole of the first magnet being exposed in the opening of the first groove; the movable body forms a second groove for accommodating a second magnet, the sidewalls and top wall of the second groove covering the outer peripheral surface and first magnetic pole of the second magnet, and the second magnetic pole of the second magnet being exposed in the opening of the second groove.

[0014] Furthermore, the movable body forms a second groove, the main body forms a first groove, and a portion of the third magnet extends into the first groove.

[0015] Furthermore, the fastener has an inclined surface, and the fastener seat has a guide slope. The inclined surface and the guide slope cooperate to facilitate the fastener entering the second window from the first window.

[0016] Furthermore, the body forms a movable cavity, the opening of which is provided with an anti-detachment flange, and the movable body is provided with a stop edge. The stop edge and the anti-detachment flange cooperate to prevent the movable body from detaching from the body.

[0017] Furthermore, the fastener is connected to a pull rope, and the fastener seat is provided with an adapter slot.

[0018] The beneficial effects of this utility model are: 1) By setting a magnetic unit in the fastener, or in both the fastener and the fastener base, the movement between the movable body and the main body is achieved by using repulsive force. This allows for quick locking of the fastener and the fastener base, and convenient unlocking. Moreover, under the presence of repulsive force, even a slight external force will cause the fastener to automatically move from the second window to the first window to unlock due to the imbalance of forces, resulting in a smooth and effortless unlocking operation; 2) The first window facilitates the overall insertion of the fastener into the fastener base, while the second window facilitates a stable connection between the fastener and the fastener base, preventing the fastener from easily detaching from the fastener base; 3) The specific structural design of the main body and the movable body makes the repulsive force generated by the magnetic unit relatively concentrated and larger. This results in a stable structure when locking and a light and effortless unlocking operation; 4) The design of the adsorption component facilitates the stable adsorption of the fastener when it is inserted into the first window, without increasing the difficulty of switching the fastener from the first window to the second window. When switching the fastener from the second window to the first window, it can assist in adsorbing the fastener, increasing the smoothness of the switching; 5) The overall structure is simple, and the user experience is highly convenient.

Detailed Implementation

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0035] A quick-release buckle includes a fastener 1, a buckle seat 2 having a first window 21 and a second window 22, and a magnetic unit 3. The fastener 1 includes at least a body 11 and a movable body 12 movably connected to the body 11. The first window 21 of the buckle seat 2 allows the fastener 1 to extend freely, and the second window 22 is used to engage the fastener 1, so that the fastener 1 is securely connected to the buckle seat 2.

[0036] Specifically, the first window 21 has a larger open area, allowing the fastener 1 to be inserted entirely into it. The second window 22 has a smaller open area, allowing part of the fastener 1 to extend out from it, while the body 11 is located inside the second window 22, thus achieving a snap-fit ​​connection between the fastener 1 and the fastener base 2. Here, the first window 21 and the second window 22 are interconnected, and the fastener 1 can only slide between the first window 21 and the second window 22 along the inner bottom surface of the fastener base 2.

[0037] The magnetic unit 3 can be provided only in the fastener 1, or the magnetic unit 3 can be provided between the fastener 1 and the fastener base 2, which is used to drive the movable body 12 to move away from the body 11.

[0038] Fastener 1 can switch between the first window 21 and the second window 22 under the action of external force. When fastener 1 enters the second window 22, the movable body 12 moves away from the main body 11, thereby making fastener 1 and fastener seat 2 snap together, and part of the movable body 12 extends out of the second window 22. This does not mean that the movable body 12 only moves away from the main body 11 when fastener 1 enters the second window 22. Alternatively, the magnetic unit 3 can keep the movable body 12 in a state of moving away from the main body 11, so that when fastener 1 enters the second window 22, the movable body 12 is also in a state of moving away from the main body 11.

[0039] The movable connection between the main body 11 and the movable body 2 is specifically achieved by forming a movable cavity 112 in the main body 11, providing an anti-detachment flange 113 at the opening of the movable cavity 112, and providing a retaining edge 122 on the outer ring of the movable body 12. When the movable body 12 is assembled into the movable cavity 112, the retaining edge 122 and the anti-detachment flange 113 engage to prevent the movable body 12 from detaching from the main body 11, while allowing the movable body 12 to move up and down within a certain range. For ease of assembly, the main body 11 can be formed by splicing two upper and lower parts.

[0040] like Figures 1-6 As shown, the magnetic unit 3 is disposed between the fastener 1 and the fastener seat 2, or in other words, part of the magnetic unit 3 is disposed in the fastener 1 and part of it is disposed in the fastener seat 2. Specifically, the magnetic unit 3 includes a third magnet 33 disposed in the fastener 1 and a fourth magnet 34 disposed in the fastener seat 2 corresponding to the second window 22, wherein the third magnet 33 and the fourth magnet 34 repel each other.

[0041] Specifically, a first groove 111 is formed on the side of the main body 11 facing the movable body 12, and a second groove 121 is formed on the side of the movable body 12 facing the main body 11. The first groove 111 and the second groove 121 are directly opposite each other. A portion of the third magnet 33 extends into the second groove 121 and is connected to it, while the remaining portion of the third magnet 33 protrudes out of the second groove 121.

[0042] The buckle 2 is provided with an adsorption element 23 at the position corresponding to the first window 21. The adsorption element 23 can be a metal sheet or a magnet, so as to attract the buckle 1. Specifically, when the buckle 1 is close to the first window 21 of the buckle 2, the adsorption element 23 will firmly adsorb the buckle 1 onto the buckle 2, and when an external force is applied to push the buckle 1 away from the first window 21, a large force is not required.

[0043] like Figure 2 , Figure 7 As shown, when the fastener 1 is placed into the first window 21 of the fastener seat 2, the fastener 1 is attracted and fixed on the fastener seat 2 due to the interaction between the third magnet 33 and the adsorption member 23. At this time, the third magnet 33 drives the movable body 12 to approach the main body 11.

[0044] like Figure 3 , Figure 8 As shown, when an external force is applied to pull or push the fastener 1 relative to the fastener base 2, the fastener 1 switches from the first window 21 to the second window 22. For easy automatic switching, as shown... Figure 4 As shown, the fastener 1 is provided with an inclined surface 13. Taking the direction shown in the figure as an example, the inclined surface 13 is inclined from top to bottom and from left to right. A guide inclined surface 24 is provided on the top surface of the fastener 2. The guide inclined surface 24 is also inclined from top to bottom and from left to right. Thus, the inclined surface 13 and the guide inclined surface 24 cooperate, and the movable body 12 automatically moves downward and closes to the main body 11, which facilitates the fastener 1 to switch smoothly from the first window 21 to the second window 22.

[0045] like Figure 5 , Figure 9 As shown, once the fastener 1 enters the second window 22, due to the mutual repulsion between the fourth magnet 34 and the third magnet 33, the position of the fourth magnet 34 is relatively fixed, and the third magnet 33 moves upward, thereby moving the movable body 12 upward, so that part of the movable body 12 extends out of the second window 22 and interferes with the wall near the second window 22 corresponding to the fastener 2. The fastener 1 cannot move relative to the fastener 2, thus achieving a stable connection between the two.

[0046] In order to make the repulsive force between the third magnet 33 and the fourth magnet 34 sufficiently large, the portion of the third magnet 33 protruding from the second groove 121 extends into the first groove 111. The first groove 111 and the second groove 121 are completely aligned vertically, so that the magnetic poles of the third magnet 33 can be closer to the fourth magnet 34, and the repulsive force between them is greater. Furthermore, since the sidewalls of the third magnet 33 are covered by the first groove 11, its magnetic force can also be concentrated on the magnetic poles, ensuring that the repulsive force is sufficiently large.

[0047] like Figure 6 As shown, when it is necessary to unlock the fastener 1 and the buckle 2, an external force is applied to press down the fastener 1, causing the movable body 12 to move downward and close to the main body 11. At this time, due to the large repulsive force between the third magnet 33 and the fourth magnet 34, and the superimposed effect of the adsorption component 23, the fastener 1 can automatically move towards the first window 21, thereby realizing the unlocking operation of the fastener 1 and the buckle 2.

[0048] like Figures 10-14 As shown, the magnetic unit 3 is disposed on the fastener 1, and includes a first magnet 31 connected to the body 11 and a second magnet 32 ​​connected to the movable body 12. The first magnet 31 and the second magnet 32 ​​repel each other.

[0049] A first groove 111 is formed on the side of the main body 11 facing the movable body 12. The first magnet 31 is accommodated and fixedly connected in the first groove 111. The sidewalls and bottom walls of the first groove 111 cover the outer peripheral surface of the first magnet 31 and the first magnetic pole 311. The second magnetic pole 312 of the first magnet 31 is exposed at the opening of the first groove 111, so that the magnetism is concentrated on the second magnetic pole 312 of the first magnet 31.

[0050] A second groove 121 is formed on the side of the movable body 12 facing the main body 11. The first groove 111 and the second groove 121 are directly opposite each other. The second magnet 32 ​​is accommodated and fixedly connected in the second groove 121. The sidewalls and top walls of the second groove 121 cover the outer peripheral surface of the second magnet 32 ​​and the first magnetic pole 321. The second magnetic pole 322 of the second magnet 32 ​​is exposed at the opening of the second groove 121, so that the magnetism is concentrated on the second magnetic pole 312 of the second magnet 32.

[0051] Here, the second magnetic pole 312 of the first magnet 31 and the second magnetic pole 312 of the second magnet 32 ​​are the same. They can both be S poles or both be N poles, thus achieving mutual repulsion and a relatively large repulsive force.

[0052] like Figure 11 As shown, when the fastener 1 is placed into the first window 21 of the fastener seat 2, the fastener 1 is attracted and fixed on the fastener seat 2 due to the interaction between the first magnet 31 and the adsorption member 23. At this time, the second magnet 32 ​​and the first magnet 31 repel each other, which drives the movable body 12 away from the main body 11.

[0053] like Figure 12 As shown, when an external force is applied to press down the movable body 12, and at the same time pulls or pushes the fastener 1 to move relative to the fastener seat 2, the fastener 1 switches from the first window 21 to the second window 22. With the cooperation of the inclined surface 13 and the guide inclined surface 24, the fastener 1 smoothly switches from the first window 21 to the second window 22.

[0054] like Figure 13 As shown, once the fastener 1 enters the second window 22 and the downward pressure is stopped, the first magnet 31 and the second magnet 32 ​​repel each other, and the second magnet 32 ​​moves the movable body 12 upward, causing part of the movable body 12 to extend out of the second window 22 and interfere with the wall surface near the second window 22 corresponding to the fastener 2. The fastener 1 cannot move relative to the fastener 2, thus achieving a stable connection between the two.

[0055] like Figure 14As shown, when it is necessary to unlock the fastener 1 and the buckle 2, an external force is applied to press down the fastener 1, causing the movable body 12 to move downward and close to the main body 11. At this time, due to the large repulsive force between the first magnet 31 and the second magnet 32, combined with the effect of the adsorption component 23, or the combined pushing force, the fastener 1 can automatically move towards the first window 21, thereby realizing the unlocking operation of the fastener 1 and the buckle 2.

[0056] like Figure 7 As shown, the fastener 1 is connected to a pull rope 4, and the buckle seat 2 is provided with an adapter slot 25. The adapter slot 25 and the pull rope 4 can be used to connect a camera, mobile phone, wearing rope, back strap, shoulder strap, etc., respectively, without any specific restrictions.

[0057] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
