Description

Technical Field

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

[0002] Quick-release buckles are commonly used for outdoor camera use. Users attach their cameras to backpack shoulder straps via quick-release buckles, allowing for quick detachment or reattachment when needed. Traditional quick-release buckles typically use elastic elements for the snap-on connection. After the buckle moves into the buckle holder, the elastic element provides spring force to engage the buckle and holder. Unlocking occurs when the elastic force of the element is overcome, allowing the buckle to detach from the holder and the camera to be removed from the shoulder strap. However, these elastic elements are easily triggered by external impacts, resulting in poor connection stability and potentially causing the camera to fall off the shoulder strap. Utility Model Content

[0003] The present invention provides a quick-release buckle to solve the technical problem that traditional quick-release buckles cause cameras attached to backpack shoulder straps to fall off due to poor connection stability.

[0004] This utility model discloses a quick-release buckle, comprising:

[0005] The fastener body is provided with a first magnetic attraction part;

[0006] The fastener includes a base, an unlocking component, and a resetting component. The base has a communicating mounting groove and a fastening groove. The unlocking component includes a pressing end and a limiting end. The pressing end is movably installed in the mounting groove, and the limiting end extends from the mounting groove into the fastening groove. The resetting component is located between the unlocking component and the base. The inner sidewall of the fastening groove away from the mounting groove forms a blocking surface.

[0007] The base is provided with a second magnetic attraction part, and the buckle can enter the buckle groove through the opening of the buckle groove. The magnetic force between the second magnetic attraction part and the first magnetic attraction part drives the buckle to be misaligned with the opening of the buckle groove. After being misaligned with the opening of the buckle groove, the buckle is limited between the blocking surface and the limiting end.

[0008] When the pressing end rotates or moves relative to the seat, the limiting end moves synchronously away from the buckle body to release the space for the buckle body to move. This space allows the buckle body to overcome the magnetic force of the first magnetic part and the second magnetic part to move to align with the opening of the buckle groove.

[0009] In one embodiment, the inner wall of the buckle groove away from the mounting groove is recessed to form an end limiting groove, and the blocking surface is formed on the bottom wall of the end limiting groove. When the buckle body is limited between the end face of the limiting end and the blocking surface, the end portion of the buckle body away from the mounting groove is limited within the end limiting groove.

[0010] In one embodiment, the inner wall of the end limiting groove is adapted to be attached to the outer wall surface of the end of the buckle; and / or, the end face of the limiting end is adapted to be attached to the outer wall surface of the buckle.

[0011] In one embodiment, the pressing end is rotatably connected to the inner wall of the mounting groove via a rotating shaft, the rotating shaft passing through the pressing end and the seat in sequence; when the buckle is limited between the end face of the limiting end and the blocking surface, operating the pressing end causes the unlocking member to flip up and down relative to the seat, the limiting end flips towards the bottom of the mounting groove and away from the buckle, or the limiting end flips outward from the mounting groove and away from the buckle.

[0012] In one embodiment, the reset member includes a telescopic spring that extends and retracts along the depth direction of the mounting groove; and / or, the reset member includes a torsion spring that is passed through the pivot.

[0013] In one embodiment, the side surface of the limiting end facing the opening of the buckle groove is recessed to form a guide groove, and the guide groove extends away from the pressing end to the edge of the limiting end. When the limiting end flips towards the bottom of the mounting groove and disengages from the buckle body, the buckle body can move along the guide groove until the buckle body is aligned with the opening of the buckle groove.

[0014] In one embodiment, the first magnetic attraction part and the second magnetic attraction part are magnetic blocks, the buckle body is provided with a first placement groove for the first magnetic attraction part to be accommodated, and the seat body is provided with a second placement groove for the second magnetic attraction part to be accommodated at the part forming the buckle groove.

[0015] In one embodiment, the first magnetic part is a magnet block, the second magnetic part and the buckle base are integrally formed metal blocks, and the buckle body is provided with a placement groove for the first magnetic part to be received.

[0016] Alternatively, the second magnetic part is a magnet block, and the first magnetic part and part of the buckle body are integrally formed metal blocks, and the buckle seat has a placement groove for the second magnetic part to be received at the part that forms the buckle groove.

[0017] In one embodiment, the buckle groove and the mounting groove are located on the same side of the base body, the depth direction of the buckle groove is consistent with the depth direction of the mounting groove, a crossbeam is provided between the opening of the buckle groove and the opening of the mounting groove, the limiting end passes through the crossbeam from the mounting groove and enters the buckle groove, and the crossbeam can prevent the unlocking member from disengaging from the mounting groove along the depth direction of the mounting groove.

[0018] In one embodiment, the buckle body is provided with a connecting rope, and the blocking surface is provided with a channel connecting the buckle groove to the outside. When the buckle body is fastened in the buckle groove, the channel allows the connecting rope to pass through and extend out of the buckle seat for the user to wear or hang.

[0019] And / or, the seat body has a through hole at the end away from the buckle groove, the through hole for the strap body to pass through and connect.

[0020] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0021] This utility model provides a quick-release buckle with a triple assembly connection between the buckle body and the buckle seat. This connection is achieved through the alignment and magnetic attraction of the first and second magnetic parts, the buckle body being misaligned within the buckle slot opening, and the buckle body being limited between the limiting surface and the limiting end. This significantly improves the overall connection stability of the quick-release buckle. Furthermore, the user only needs to press a button to release the limiting end's restriction on the buckle body. The buckle body then detaches from the buckle slot by external force overcoming the magnetic force between the two magnetic parts, thus separating the buckle body from the buckle seat and disconnecting the quick-release buckle. Therefore, this quick-release buckle offers high connection stability and convenient assembly / disassembly. When users need to free their hands during outdoor activities, they can attach their camera to the backpack shoulder strap using this quick-release buckle for convenient shooting and use.

[0035] Please refer to Figure 1and Figure 2 This utility model provides a novel quick-release buckle 10, which includes a buckle body 100 and a buckle seat 200 for quick assembly and disassembly. The buckle body 100 is used to connect a first component, and the buckle seat 200 is used to connect a second component. The first component can be a movable object such as a camera, mobile phone, key, or toy. In this case, the second component can be a strap such as a lanyard or backpack shoulder strap. The strap is then worn on various parts of the body, such as the wrist, neck, shoulder, or waist. The buckle body 100 and the buckle seat 200 are fastened together, allowing the user to attach the movable object to various parts of the body using the quick-release buckle 10, freeing the user's hands and making it convenient for the user to use the movable object at any time. For example, during outdoor activities, a camera can be attached to a backpack shoulder strap using the quick-release buckle 10, allowing the user to stop at any time to take pictures of the scenery along the way. It should be understood that in other embodiments, the type and location of the first and second components are not limited. In terms of type, it needs to be adapted to the user's usage requirements. In terms of connection location, the positions of the first and second components connected to the quick-release buckle 10 can be interchanged.

[0036] Reference Figure 3-5 The buckle body 100 is provided with a first magnetic attraction part 110, and the buckle base 200 includes a base body 210, an unlocking member 220, a resetting member 230, and a second magnetic attraction part 240. The base body 210 serves as the main body of the buckle base 200. The unlocking member 220 is used to lock or release the buckle body 100 from the buckle base 200. The second magnetic attraction part 240 is aligned and magnetically attracted with the first magnetic attraction part 110 to enhance the assembly stability of the buckle body 100 and the buckle base 200. The resetting member 230 provides a resetting force to drive the unlocking member 220 to lock the buckle body 100 into the buckle base 200. The base 210 is provided with a communicating mounting groove 211 and a buckle groove 212. The unlocking member 220 includes a pressing end 221 and a limiting end 222. The pressing end 221 is movably installed in the mounting groove 211. The limiting end 222 extends from the mounting groove 211 into the buckle groove 212. The buckle groove 212 forms a blocking surface 213 on the inner side wall away from the mounting groove 211. The reset member 230 is provided between the unlocking member 220 and the base 210. The second magnetic suction part 240 is provided on the base 210 and located in the buckle groove 212.

[0037] Combination Figure 4 and Figure 5The buckle body 100 can enter the buckle groove 212 through the opening of the buckle groove 212. The magnetic attraction between the second magnetic attraction part 240 and the first magnetic attraction part 110 drives the buckle body 100 to be misaligned with the opening of the buckle groove 212. After being misaligned with the opening of the buckle groove 212, the buckle body 100 is limited between the blocking surface 213 and the limiting end 222. It is understandable that during the process of the user inserting the buckle body 100 into the buckle groove 212 along the depth direction of the buckle groove 212, the buckle body 100 will simultaneously press the limiting end 222 to make the unlocking part 220 move relative to the seat body 210, and the reset part 230 accumulates the reset force; then the two magnetic parts are aligned and magnetically attracted, driving the buckle body 100 to move away from the mounting groove 211 and abut against the blocking surface 213, and the reset part 230 releases the reset force to drive the limiting end 222 to abut against the buckle body 100, thereby limiting the buckle body 100 between the blocking surface 213 and the limiting end 222, so as to realize the assembly connection between the buckle body 100 and the buckle seat 200, that is, the quick-release buckle 10 is in the locked state (e.g. Figure 2 (or as shown in Figure 4).

[0038] Continue to combine Figure 4 and Figure 5 When the user operates the pressing end 221 to rotate or move relative to the seat 210, the limiting end 222 moves synchronously away from the buckle body 100 to release the space for the buckle body 100 to move, that is, the quick-release buckle 10 is in the locked state (e.g. Figure 1 (As shown in Figure 5), this space allows the buckle body 100 to overcome the magnetic force between the first magnetic part 110 and the second magnetic part 240 to move to the opening of the buckle groove 212 for alignment, so as to remove the buckle body 100 from the buckle groove 212 and disconnect the connection between the buckle body 100 and the buckle seat 200.

[0039] The quick-release buckle 10 provided by this utility model features a triple assembly connection between the buckle body 100 and the buckle seat 200. This connection is achieved through the alignment and magnetic attraction of the first magnetic attraction part 110 and the second magnetic attraction part 240, the buckle body 100 being installed in the buckle groove 212 for fastening, and the buckle body 100 being limited between the blocking surface 213 and the limiting end 222. This significantly improves the overall connection stability of the quick-release buckle 10. Moreover, the user only needs to press the end 221 with one button to release the limiting end 222 from the buckle body 100. The buckle body 100 then overcomes the magnetic force between the two magnetic attraction parts and disengages from the buckle groove 212, separating the buckle body 100 from the buckle seat 200 and disconnecting the quick-release buckle 10. Therefore, the quick-release buckle of this application has high connection stability and is easy to install and remove. When users need to free their hands during outdoor activities, they can attach the camera to the backpack shoulder strap via the quick-release buckle 10 for convenient shooting and use.

[0040] Preferably, in conjunction with reference Figure 1 and Figure 3In one embodiment, the inner wall of the buckle groove 212, away from the mounting groove 211, is recessed to form an end limiting groove 214. A blocking surface 213 is formed on the bottom wall of the end limiting groove 214. When the buckle body 100 is limited between the limiting end 222 and the blocking surface 213, the end portion of the buckle body 100 away from the mounting groove 211 is limited within the end limiting groove 214. It is easy to understand that the end limiting groove 214 effectively prevents the end of the buckle body 100 away from the mounting groove 211 from tilting away from the buckle groove 212 and detaching from the buckle groove 212, thereby further improving the connection stability of the entire quick-release buckle 10. Of course, in other embodiments, the end limiting groove 214 may not be provided.

[0041] Preferably, in conjunction with reference Figure 1 , Figure 3 , Figure 4 In one embodiment, the inner wall of the end limiting groove 214 is adapted to be attached to the outer wall surface of the end of the buckle body 100; furthermore, the end face of the limiting end 222 is also adapted to be attached to the outer wall surface of the buckle body 100. This design significantly reduces the assembly gap of the entire quick-release buckle 10, thereby further improving the assembly compactness of the quick-release buckle 10. Here, the buckle body 100 includes, but is not limited to, regular columnar, spherical, or hexahedral shapes. It should be noted that, without considering assembly compactness, the shape of the buckle body 100 is not limited in this application, and the state of the inner wall of the end limiting groove 214 or the end face of the limiting end 222 is not limited.

[0042] Preferably, in conjunction with reference Figure 3-5 In one embodiment, the pressing end 221 is rotatably connected to the inner wall of the mounting groove 211 via a rotating shaft 250, that is, the rotating shaft 250 passes through the pressing end 221 and the seat 210 in sequence, and the unlocking member 220 is connected to the seat 210 in a rocker-like state. When the buckle 100 is limited between the limiting end 222 and the blocking surface 213, the quick-release buckle 10 is in a locked state. Figure 4 When the pressing end 221 is pressed, the unlocking part 220 flips up and down relative to the seat 210, and the limiting end 222 flips towards the bottom of the mounting groove 211 and moves away from the buckle body 100, or the limiting end 222 flips outward away from the bottom of the mounting groove 211 and moves away from the buckle body 100, and the quick-release buckle 10 switches to the unlocked state. Figure 5 At this point, the user can remove the buckle body 100 from the buckle groove 212 and disconnect the connection between the buckle body 100 and the buckle seat 200.

[0043] It should be noted that in other embodiments of this application (not shown in the figures), at the contact position between the pressing end 221 and the mounting groove 211, one is provided with a protrusion and the other with a slide rail. The protrusion slides from one end of the slide rail to the other end, and the pressing end 221 is slidably connected to the mounting groove 211. The pressing end 221 moves relative to the base 210 to allow the reset member 230 to accumulate or release reset force, and drives the limiting end 222 to move synchronously closer to or away from the buckle body, allowing the quick-release buckle 10 to switch between the locked state and the unlocked state.

[0044] It is understandable that the connection method between the pressing end 221 and the mounting groove 211 is not limited; it can be rotatably connected or slidably connected.

[0045] Optionally, in one embodiment, when the pressing end 221 is rotatably connected to the inner wall of the mounting groove 211, the reset member 230 can be a telescopic spring 231. The telescopic spring 231 accumulates or releases elastic force along the depth direction of the mounting groove 211, and its two ends are respectively fixedly connected to the unlocking member 220 and the bottom wall of the mounting groove 211. Alternatively, in one embodiment, the reset member 230 can be a torsion spring (not shown), with the torsion spring's back-rotation shaft 250 passing through it and accumulating and releasing elastic force as the unlocking member 220 rotates. Alternatively, in one embodiment, the reset member 230 can be a magnetic component, elastic rubber, or other structural object capable of providing a reset force. It should be understood that in this application, the reset member 230 can simultaneously include a telescopic spring 231 and a torsion spring, with different placement positions, but the process of accumulating and releasing reset force is the same, thus providing a reinforced reset effect. Of course, only one type of reset member 230 structure can be provided. When the pressing end 221 is slidably connected to the mounting groove 211, the reset component 230 includes, but is not limited to, a telescopic spring 231, elastic rubber, and a magnetic component. The direction of the reset force of the reset component 230 is consistent with the extension direction of the slide rail (sliding direction is consistent). Therefore, in this application, the setting position, setting structure type, and setting quantity of the reset component 230 are not limited.

[0046] Optionally, in conjunction with reference Figure 3 and Figure 5In one embodiment, the side surface of the limiting end 222 facing the opening of the buckle groove 212 is recessed to form a guide groove 223. The guide groove 223 extends away from the pressing end 221 to the edge of the limiting end 222. When the limiting end 222 flips towards the bottom of the mounting groove 211 and moves away from the buckle body 100, the buckle body 100 can move along the guide groove 223 to align with the opening of the buckle body 100 and the buckle groove 212. The user can then remove the buckle body 100 from the buckle groove 212 and disconnect the buckle body 100 from the buckle seat 200. Here, the guide groove 223 increases the movement space of the buckle body 100 when the quick-release buckle 10 is in the unlocked state, further facilitating the user to remove the buckle body 100 from the buckle groove 212. Of course, in other embodiments, the movement space of the buckle body 100 in the unlocked state is not considered, so the guide groove 223 is not required.

[0047] Optionally, in conjunction with reference Figure 3 and Figure 4 In one embodiment, both the first magnetic attraction part 110 and the second magnetic attraction part 240 are magnetic blocks. The buckle body 100 is provided with a first placement groove 120 for accommodating the first magnetic attraction part 110, and the seat body 210 is provided with a second placement groove 215 for accommodating the second magnetic attraction part 240 at the location forming the buckle groove 212. Alternatively, in another embodiment (not shown), the first magnetic attraction part 110 is a magnetic block, and the second magnetic attraction part 240 and part of the structure of the seat body 210 are integrally formed metal blocks. The buckle body 100 is provided with a placement groove (i.e., the first placement groove 120) for accommodating the first magnetic attraction part 110. Alternatively, in one embodiment (not shown), the second magnetic attraction part 240 is a magnetic block, and the first magnetic attraction part 110 and part of the structure of the buckle body 100 are integrally formed metal blocks. The seat body 210 is provided with a placement groove (i.e., the second placement groove 215) for accommodating the second magnetic attraction part 240 at the location forming the buckle groove 212.

[0048] It is understandable that when the two magnetic parts are magnetically attracted to each other through two magnets, the materials of the buckle body 100 and the base body 210 are not limited; when the two magnetic parts are magnetically attracted to metal through a single magnet, at least one of the buckle body 100 and the base body 210 must have a portion of its structure made of metal. Therefore, in this application, the number of magnets and placement slots is not limited, as long as at least one set is provided. That is, at least one of the two magnetic surfaces of the buckle body 100 and the base body 210 that are magnetically attracted to each other is provided with a placement slot, which is used to place the first magnetic part 110 or the second magnetic part 240.

[0049] Preferably, combined with Figure 4 and Figure 5In one embodiment, the mounting groove 211 and the latching groove 212 are located on the same side of the base 210. The depth direction of the mounting groove 211 is consistent with the depth direction of the latching groove 212. A crossbeam 260 is provided between the opening of the mounting groove 211 and the opening of the latching groove 212. The limiting end 222 enters the latching groove 212 from the mounting groove 211 through the crossbeam 260. The crossbeam 260 can prevent the unlocking member 220 from disengaging from the mounting groove 211 along the depth direction of the mounting groove 211. That is, the crossbeam 260 restricts the excessive movement of the unlocking member 220, so as to further limit the unlocking member 220 within the mounting groove 211. For example, when the unlocking member 220 rotates relative to the base 210, the crossbeam 260 can prevent the limiting end 222 from excessively turning outward. Of course, in other embodiments, the crossbeam 260 is not required. Other slots can be provided on the inner sidewall of the mounting groove 211 to restrict the excessive movement of the unlocking member 220.

[0050] Optionally, refer to Figure 1 or Figure 2 In one embodiment, the buckle body 100 is provided with a connecting rope 130, and the blocking surface 213 is provided with a buckle groove 212 and a channel 216 connecting to the outside. When the buckle body 100 is fastened in the buckle groove 212, the channel 216 allows the connecting rope to pass through and extend out of the buckle seat 200 for the user to wear or hang. Furthermore, the end of the seat body 210 away from the buckle groove 212 is provided with a through hole 217 for the strap to pass through and connect. It can be understood that the connecting rope 130 and the through hole 217 here are respectively connected to the first component and the second component mentioned above. It should be understood that the connecting rope 130 and the through hole 217 are merely specific external structures of the quick-release buckle 10. Optionally: in one embodiment, the buckle body 100 or the base 210 may also be provided with other connecting structures for external connection; or, in one embodiment, the positions of the connecting rope 130 and the through hole 217 may be interchanged; or, in one embodiment, both the buckle body 100 and the base 210 are provided with the connecting rope 130 for external connection; or, both the buckle body 100 and the base 210 are provided with the through hole 217 for external connection. Therefore, in this application, the presence or absence of the connecting rope 130 and the through hole 217 is not limited.

[0051] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
