Description

Technical Field

[0001] This utility model relates to the field of connecting buckle technology, and specifically to a connecting buckle. Background Technology

[0002] Magnetic fasteners are widely used in clothing accessories, outdoor gear, and personal items due to their ease of use. Current technologies for magnetic fasteners primarily focus on improving connection convenience or enhancing connection stability, but often fail to achieve both simultaneously.

[0003] However, existing magnetic fasteners face two prominent technical problems in practical applications. Firstly, while the simple magnetic structure is convenient to operate, it cannot guarantee reliable connection under significant tension or continuous vibration, posing a safety hazard of accidental detachment. Secondly, the complex mechanical locking mechanisms designed to improve connection reliability, while solving the problem of firmness, often lead to complex product structures, numerous parts, increased production costs, and cumbersome operation, thus sacrificing the inherent convenience of magnetic connections.

[0004] In addition, most existing magnetic snaps adopt a single-sided design. When users use them in dimly lit environments or in a hurry, they need to spend time identifying the correct docking direction, which reduces the efficiency of use. Utility Model Content

[0005] This application discloses a connecting buckle that can improve the docking efficiency of magnetic fasteners.

[0006] One embodiment of this application discloses a connecting buckle, comprising: The connecting part is capable of connecting to an external device along a first direction, and the outer surface of the connecting part with the first direction as its axis is configured as a mating surface, and each mating surface is provided with at least one locking groove and at least one first magnet; A connecting seat, wherein the connecting seat is provided with a mounting groove for the connecting part to slide along a first direction; as well as, An adjustment assembly includes an adjustment member and an adjustment part that move synchronously along a first direction.

When the first magnet is magnetically attracted to the second magnet, the locking protrusion is embedded in the locking groove. Wherein, the first direction intersects with the second direction, and the locking protrusion and the locking groove cooperate to pull the adjustment component to move along the first direction to adjust its position.

[0007] In another embodiment, the adjusting member further includes a synchronization plate and a driving member. The synchronization plate is slidably mounted on the bottom wall of the mounting groove along a first direction.

When the adjustment part is in the locked position, the first locking structure and the second locking structure are locked to prevent the adjustment part and the connecting part from disengaging along the first direction, wherein the third direction is perpendicular to the plane containing the first direction and the second direction.

[0013] In another embodiment, the connector is provided with a locking structure that restricts the connection part from disengaging along the second direction. The locking structure includes two limiting parts disposed at the opening of the mounting groove. The mounting groove and the connection part are disposed opposite each other along the second direction. Each limiting part is arranged on both sides of the mounting groove and extends along the third direction, so that an avoidance groove is formed between the two limiting parts.

[0014] In another embodiment, the connecting part is configured as a sphere or as a cylinder with its axis arranged along a first direction, and a plurality of the locking grooves are connected to form an annular groove, and a plurality of the first magnets are connected head-to-head to form an annular magnet.

The projection of the opening along the first direction is located within the projection range of the connecting portion along the first direction, so as to restrict the connecting portion from disengaging from the mounting groove along the first direction.

[0016] The aforementioned connecting buckle, during use, utilizes the first magnet on multiple mating surfaces to attract the second magnet without needing to distinguish direction. This allows the locking groove and locking protrusion to engage, achieving overall relative fixation of the connecting part's traction adjustment component in the first direction. The connecting part and adjustment component can then slide to adjust their position for subsequent locking. This solution integrates the convenience of multi-faceted mating, the speed of magnetic attraction, and the reliability of mechanical engagement, achieving a "one-touch lock" effect on any mating surface. It solves the problems of traditional magnetic buckles being prone to detachment and inconvenient for single-sided use, improving the efficiency of magnetic buckle mating.

Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0022] Please refer to Figures 1-9This application provides a connecting buckle, the core of which is to integrate the convenience of multi-face connection, the speed of magnetic attraction and guidance and the reliability of mechanical locking into one, so that the "one-touch locking" effect can be achieved when used on any of the mating surfaces 103, solving the problems of easy detachment and inconvenience of single-sided use of traditional magnetic buckles, and improving the docking efficiency of magnetic buckles.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 A connector includes: a connecting portion 100, capable of connecting to an external device along a first direction, wherein the outer surface of the connecting portion 100 with the first direction as its axis is configured as a mating surface 103, each mating surface 103 being provided with at least one locking groove 104 and at least one first magnet 102; a connecting base 200, provided with a mounting groove 201 for the connecting portion 100 to slide along the first direction; and an adjustment assembly, the adjustment assembly including an adjustment member and an adjustment portion 300 that move synchronously along the first direction. The adjustment component is slidably disposed in the mounting groove 201 along the first direction; the adjustment component includes a locking protrusion 600 and a second magnet 700, the locking protrusion 600 extends along the second direction, the first magnet 102 and the second magnet 700 are distributed along the second direction and attract each other; when the first magnet 102 is attracted to the second magnet 700, the locking protrusion 600 is embedded in the locking groove 104; wherein, the first direction and the second direction are intersecting, and the locking protrusion 600 and the locking groove 104 cooperate to pull the adjustment component to move along the first direction for position adjustment.

[0024] In this embodiment, the mounting groove 201 has a bottom wall, two end walls arranged opposite to each other along a first direction, and two side walls arranged opposite to each other along a third direction on the connecting seat 200. The bottom wall, two end walls and two side walls on the connecting seat 200 form the mounting groove 201 in this embodiment, and the groove opening of the mounting groove 201 is formed on the side opposite to the bottom wall. The bottom wall and the groove opening are arranged opposite to each other in a second direction.

[0025] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The connecting part 100 is designed as a block structure with a certain thickness in the second direction. For example, the connecting part 100 is generally set as a trapezoidal structure, and a connecting member 101 for traction is provided at its front end along the first direction for connecting external equipment. The connecting member 101 is arranged along the first direction to ensure the rationality of the pulling force direction during use.

[0026] Specifically, in this embodiment, please refer to Figure 3The connecting part 100 has four sides on its outer surface with the first direction as the axis. The connecting part includes two mating surfaces 103 arranged along the second direction, namely the upper end surface and the lower end surface in the second direction (height). The upper end surface and the lower end surface are each provided with a corresponding locking groove 104. The upper end surface and the lower end surface are each provided with a first magnet 102 on one side of the locking groove 104. The magnetic attraction surfaces of the first magnet 102 and the second magnet 700 are arranged perpendicular to the second direction so that the two are attracted and attached along the second direction, thereby guiding the locking protrusion 600 to be locked into the locking groove 104 along the second direction, realizing the mechanical locking of the connecting part 100 and the adjustment assembly as a whole in the first direction, and ensuring the stability of the traction.

[0027] In this embodiment, please refer to Figure 3 When in use, the connecting part 100 does not need to distinguish between the front and back. Both its upper and lower ends can be placed into the mounting groove 201 and fitted with the second magnet 700, which serves as the mating surface 103. Users do not need to spend time identifying the correct mating direction, thus ensuring efficiency.

[0028] Similarly, in other embodiments, please refer to Figure 4 If the connecting part 100 adopts a multi-sided prism structure with the first direction as the axis, the mating surface 103 can be specifically designed according to the specific structure of the connecting part 100. For example, if the connecting part 100 adopts a quadrangular prism with the first direction as the axis, the mating surface 103 is set to four, and the number of the locking groove 104 and the first magnet 102 can be specifically designed according to the usage scenario.

[0029] In another embodiment, please refer to Figure 5 The connecting part 100 can be configured as a sphere or as a cylinder with its axis along a first direction. Based on this, several locking grooves 104 are connected to form an annular groove, and several first magnets 102 are connected head-to-head to form an annular magnet, thereby providing the connecting part 100 with a rotation function. The inner wall of the locking section 202 is correspondingly configured to rotate in cooperation with the outer ring of the connecting part 100, so that the connecting part 100 can still rotate 360 ​​degrees in the locked state, effectively preventing the connecting part 101 from getting tangled.

[0030] In this embodiment, please refer to Figure 3 , Figure 4 and Figure 5 In use, the connecting part 100 is directly placed into the mounting slot 201, and any position of its mating surface 103 can be engaged with the second magnet 700. At the same time, the locking groove 104 and the locking protrusion 600 cooperate to achieve locking, so that the two are relatively fixed in the first direction. The user does not need to spend time identifying the mating direction, achieving the effect of "one-touch locking".

[0031] Furthermore, the first magnet 102 and the second magnet 700 are selected as strong neodymium iron boron magnets to ensure sufficient magnetic attraction. They provide guidance during the initial connection process, helping the user to quickly and accurately align the position; they provide auxiliary holding force during connection, allowing the connector 101 to pull the connecting part 100 and simultaneously move the adjusting part 300; and they provide additional safety in the locked state in a second direction.

[0032] In this embodiment, the connecting part 100 is provided with a connector 101 arranged along the first direction. The connector can be a connecting rope, connector 101, connecting strap, etc., for connecting external devices, such as cameras, tool bags, etc. The connecting seat 200 is fixedly installed on another object that needs to be connected, such as a backpack shoulder strap, waist belt, etc. The adjusting part 300 realizes the sliding and locking functions inside the connecting seat 200. The driving part 400 provides the power for automatic locking.

[0033] In this embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The first direction is set as the length direction of the connecting seat 200, the connecting member 101, the mounting groove 201, and the sliding direction of the adjusting part 300. The second direction is set as the height direction of the connecting seat 200. In subsequent embodiments, the third direction is the width direction of the connecting seat 200, the connecting member 101, and the mounting groove 201. The first direction, the second direction, and the third direction are set perpendicular to each other. The free position and the locking position are arranged along the second direction, that is, in the height direction, the locking position is set above the free position.

[0034] Furthermore, the groove 104 and the mating surface 103 can be designed as a smoothly transitioning slope or arc surface so that the protrusion 600 can be embedded.

[0035] Please refer to Figure 3 , Figure 4 and Figure 5 The connecting seat 200 has an opening 203 at one end along the first direction, which communicates with the mounting groove 201 and allows the connecting member 101 to pass through. The opening 203 communicates with any end wall of the mounting groove 201. In this embodiment, the opening 203 is a semi-open hole that communicates with the mounting groove 201. The connecting part 100 is placed between the end wall where the opening 203 is located and the adjusting part 300. The projection of the inner circle of the opening 203 along the first direction is located within the range of the projection of the outer surface of the connecting part 100 at the corresponding position, so as to limit the connecting part 100 from leaving the mounting groove 201 along the first direction.

[0036] In this embodiment, please refer to Figure 1 and Figure 2The projections of the opening 203 and the connecting part 100 along the first direction fall on the plane formed by the second and third directions. The projection of the opening 203 falls within the projection range of the outer surface of the connecting part 100, thereby making the opening 203 a buffer for the connecting member 101 while preventing the connecting part 100 from disengaging from the connecting seat 200 in the first direction.

[0037] For further details, please refer to... Figure 2 and Figure 3 The connecting seat 200 is the basic frame of the entire device, and its interior is provided with a mounting groove 201 for the connecting part 100 and the adjusting part 300 to slide along a first direction. The connecting seat 200 can be divided into a mounting section and a locking section 202 along the first direction. The mounting groove 201 corresponding to the mounting section is used to guide the connecting part 100 to enter smoothly, and the mounting groove 201 corresponding to the locking section 202 is the final locking position of the connecting part 100. In this embodiment, the locking section 202 is located between the end wall where the opening 203 is located and the adjusting part 300, and is arranged close to the side of the end wall where the opening 203 is located. At the same time, the opening 203 provides sufficient passage space for the connecting part 101 and also acts as a mechanical barrier to prevent the connecting part 100 from disengaging from the mounting groove 201 along the first direction.

[0038] Please refer to Figure 3 Figures 6(a) and 6(b) show that the locking segment 202 serves as the final locking position of the connecting part 100. It is equipped with a locking structure to prevent the connecting part 100 from disengaging in the second direction. Specifically, the locking structure includes two limiting parts 204 disposed at the opening of the mounting groove 201. Each limiting part 204 is arranged on both sides of the opening of the mounting groove 201 and extends inward in the third direction. A clearance groove 205 for the connecting member 101 to pass through is formed between the two limiting parts 204. In this embodiment, the opening of the mounting groove 201 is located on the upper surface of the connecting seat 200, and the connecting part 100 does not extend beyond the opening of the mounting groove 201 in the second direction.

[0039] Specifically, please refer to Figures 6, 6(a), and 6(b). The limiting part 204 is the constricted structure of the slot of the locking section 202. It shrinks inward relative to the mounting groove 201, so that the distance between the two limiting parts 204 is no greater than the outer surface of the connecting part 100, thereby restricting the connecting part 100 from disengaging from the clearance groove 205 from the mounting groove 201 in the second direction. In other words, the projection of the clearance groove 205 in the second direction is within the range of the projection of the outer surface of the connecting part 100 at the corresponding position. That is, the projections of the clearance groove 205 and the connecting part 100 in the second direction fall on the plane formed by the first direction and the third direction, and the projection of the clearance groove 205 falls within the projection range of the outer surface of the connecting part 100.

[0040] For further details, please refer to... Figure 3 , Figure 4 and Figure 5 The adjustment assembly also includes a synchronization plate 500 and a drive member 400. The synchronization plate 500 is slidably mounted on the bottom wall of the mounting groove 201 along a first direction. The second magnet 700, the drive member 400, and the locking protrusion 600 are all disposed on the synchronization plate 500. The adjustment part 300 is stacked on the synchronization plate 500 along a second direction. The adjustment part 300 has a free position and a locked position along the second direction. One end of the drive member 400 along the second direction is mounted on the synchronization plate 500, and the other end is used to connect to the adjustment part 300 to push the adjustment part 300 from the free position to the locked position. The bottom wall of the mounting groove 201 has a guide groove 209 arranged along the first direction. The synchronization plate 500 is slidably mounted on the guide groove 209, and the locking protrusion 600 is distributed in the first direction between the locking section 202 and the adjustment part 300.

[0041] In this embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The sliding of the synchronization plate 500, the locking protrusion 600, the second magnet 700, the drive component 400, and the adjustment part 300 in the mounting groove 201 along the first direction is consistent and integral. The adsorption of the first magnet 102 and the second magnet 700, and the cooperation between the locking groove 104 and the locking protrusion 600, connect the connecting part 100 and the adjustment component into a whole in the first direction, so that the sliding of the two along the first direction is consistent, integral, and stable.

[0042] For further details, please refer to... Figure 3 , Figure 7 , Figure 8 and Figure 9 The adjusting part 300 is the core component for achieving automatic locking. The adjusting part 300 and the connecting seat 200 are equipped with a locking structure that restricts the movement of the adjusting part 300 along the first direction. Specifically, the mounting groove 201 has a first locking structure on both side walls along the third direction, and the adjusting part 300 has a second locking structure on its outer surface along the third direction.

Both the first guide surface 206 and the second guide surface 302 extend along the first direction in their length direction and along the third direction in their width direction. When the adjusting part 300 is in the locked position, the first guide surface 206 and the second guide surface 302 are far apart from each other, and the first... The guide surface 206 is located between the second guide surface 302 and the bottom wall of the mounting groove 201 in the second direction. The first guide surface 206 and the second guide surface 302 are offset in the first direction. When the adjustment part 300 is in the free position, the first guide surface 206 contacts the second guide surface 302, and the projections of the first guide surface 206 and the second guide surface 302 in the second direction have an overlapping area. The second guide surface 302 is located between the first guide surface 206 and the bottom wall of the mounting groove 201 in the second direction to restrict the adjustment part 300 from disengaging from the mounting groove 201 in the second direction.

[0044] In this embodiment, please refer to Figure 3 , Figure 7 , Figure 8 and Figure 9 The free position, i.e., the second guide surface 302 is located between the first guide surface 206 and the bottom wall of the mounting groove 201, and the adjustment part 300 can slide in the mounting groove 201. At this height, the sliding state of the adjustment part 300 is always in the free position until it reaches the tail end where the first guide surface 206 and the second guide surface 302 contact. The upper and lower ends of the adjustment part 300 along the second direction are respectively restricted by the mounting groove 201 and the first guide surface 206, thereby preventing the adjustment part 300 from disengaging from the mounting groove 201 along the second direction when sliding.

[0045] For further details, please refer to... Figure 3 , Figure 7 , Figure 8 and Figure 9The first locking structure further includes a first locking surface 207 perpendicular to the first direction, i.e., the first locking surface 207 is perpendicular to the first guide surface 206, and the first locking surface 207 is disposed in the second direction on the side of the first guide surface 206 away from the bottom wall of the mounting groove 201. The first locking surface 207 is disposed in the first direction on the side of the first guide surface 206 near the locking section 202, and the first locking surface 207 is connected to the first guide surface 206 in the second direction and extends toward the side away from the bottom wall of the mounting groove 201. The second locking structure further includes a second locking surface 303 perpendicular to the first direction. The second locking surface 303 is perpendicular to the second guide surface 302, and the second locking surface 303 is disposed in the second direction on the side of the second guide surface 302 near the locking section 202.

The second locking surface 303 is connected to the second guide surface 302 and extends toward the side of the bottom wall of the mounting groove 201. When the adjustment part 300 is in the free position, the first locking surface 207 and the second locking surface 303 are misaligned in projection along the first direction. The second locking surface 303 is located between the first locking surface 207 and the bottom wall of the mounting groove 201 in the second direction. When the adjustment part 300 is in the locked position, the first locking surface 207 and the second locking surface 303 have an overlapping area in projection along the first direction to restrict the adjustment part 300 from moving away from the connecting part 100 along the first direction.

[0046] For further details, please refer to... Figure 3 , Figure 7 , Figure 8 and Figure 9 The first locking structure further includes a first auxiliary surface 208, wherein the first auxiliary surface 208, the first locking surface 207, and the first guide surface 206 are arranged in a stepped structure, and the first auxiliary surface 208 is parallel to the first guide surface 206; the second locking structure further includes a second auxiliary surface 304, wherein the second auxiliary surface 304, the second locking surface 303, and the second guide surface 302 are arranged in a stepped structure, and the second auxiliary surface 304 is parallel to the second guide surface 302. When the adjusting part 300 is in the free position, the first auxiliary surface 208 and the second auxiliary surface 304 are misaligned in projection along the first direction and / or the second direction; when the adjusting part 300 is in the locked position, the second auxiliary surface 304 and the first guide surface 206 are in contact, and / or the second guide surface 302 and the first auxiliary surface 208 are in contact, to restrict the adjusting part 300 from disengaging along the second direction.

[0047] In this embodiment, please refer to Figure 3 , Figure 7 , Figure 8 and Figure 9After the locking position, i.e., the adjustment part 300, slides to the tail end of the first guide surface 206, it rises in the second direction under the action of the driving member 400, and the second guide surface 302 is higher than the first guide surface 206 in the second direction. At this time, in the first direction, one side of the adjustment part 300 is restricted by the connecting part 100, and the other side is prevented from moving in the first direction by the misalignment of the first locking surface 207 and the second locking surface 303; in the second direction, the lower end of the adjustment part 300 is restricted by the synchronous plate 500, and the upper end is prevented from disengaging in the second direction by the contact of the second auxiliary surface 304 and the first guide surface 206 and / or the contact of the second guide surface 302 and the first auxiliary surface 208; in the third direction, the adjustment part 300 is restricted by the inner wall of the mounting groove 201 to prevent the adjustment part 300 from disengaging in the third direction.

[0048] Under the premise of adjusting the 300 lock, please refer to Figure 3 , Figure 7 , Figure 8 and Figure 9 At this time, in the first direction, one side of the connecting part 100 is restricted by the end wall on the side of the opening 203 of the mounting groove 201, and the other side is restricted by the adjusting part 300, thereby preventing the connecting part 100 from detaching in the first direction; in the second direction, the lower end of the connecting part 100 is restricted by the synchronization plate 500, and the upper end is restricted by the limiting part 204, thereby preventing the connecting part 100 from detaching in the second direction; in the third direction, the connecting part 100 is restricted by the inner side wall of the mounting groove 201, thereby preventing the adjusting part 300 from detaching in the third direction.

[0049] For further details, please refer to... Figure 3 and Figure 7 The driving component 400 provides the power for automatic locking of the adjusting part 300, and includes a base 401 and a spring 402 disposed on the base 401. The bottom of the adjusting part 300 has a cavity 305 for accommodating the driving component 400. The lower end of the base 401 along the second direction is fixed to the synchronous plate 500, and the upper end extends into the cavity 305 and is movably connected to the adjusting part 300 in the second direction. The spring 402 is arranged along the second direction. The spring 402 is always in a compressed state so that it always has a force to push the adjusting part 300 upward in the second direction, thereby automatically rising under the action of elastic force when the adjusting part 300 reaches the tail end of the first guide surface 206.

[0050] In this embodiment, please refer to Figure 3 The driving component 400 and the locking protrusion 600 are respectively set at both ends of the synchronization plate 500 along the first direction to leave space for the installation and docking of the connecting part 100 and the adjusting part 300.

[0051] For further details, please refer to... Figure 3The adjustment section 300 is inclined along its upper surface in the second direction, and its thickness gradually increases from the side near the locking section 202 to the side away from the locking section 202. This inclined surface design is not only ergonomic, facilitating user pressing operations, but also provides the necessary space for the locking structure. Simultaneously, the entire upper surface is provided with several parallel anti-slip strips 301, and the length direction of the anti-slip strips 301 is angled to the first direction; preferably, the length direction of the anti-slip strips 301 is perpendicular to the first direction, so that the user can obtain better friction during operation, facilitating the application of force.

[0052] The working principle of this embodiment is as follows: When the user needs to connect, firstly, align the connecting part 100 with the entrance of the mounting groove 201 of the connecting seat 200 and place it between the end wall where the adjusting part 300 and the opening 203 are located. Without confirming the mating surface 103, directly place the connecting part 100 into the mounting groove 201. Due to the mutual attraction between the first magnet 102 and the second magnet 700 in the second direction, the connecting part 100 will automatically align and initially adhere to the adjusting part 300. At this time, the locking protrusion 600 simultaneously extends into the locking groove 104 and engages. The connecting part 101 is arranged along the first direction at the positions of the clearance groove 205 and the opening 203, without interference. The user only needs to pull the connecting part 101 along the first direction, and the connecting part 100, through the cooperation of the locking protrusion 600 and the locking groove 104, pulls the adjusting part 300 to one side of the locking section 202 and the locking structure.

[0053] During the sliding process, the connecting part 100 gradually enters the locking section 202, at which point the limiting part 204 begins to function, restricting the movement of the connecting part 100 in the second direction.

[0054] When the connecting part 100 and the adjusting part 300 slide to the predetermined position, that is, when they reach the tail end of the first guide surface 206, the driving member 400 begins to play a key role. Since the adjusting part 300 is no longer subject to other constraints at its upper end in the second direction, the elastic force of the spring 402 will push the adjusting part 300 to rise from the free position to the locked position along the second direction.

[0055] In the locked position, the connecting portion 100 is constrained in the first direction between the end of the mounting groove 201 and the adjusting portion 300, and is kept relatively fixed to the adjusting portion 300 by the engagement of the locking groove 104 and the locking protrusion 600. The engagement of the first locking structure and the second locking structure restricts the movement of the adjusting portion 300 in the first direction, thereby indirectly restricting the movement of the connecting portion 100 in the first direction. In the second direction, the connecting portion 100 is constrained between the synchronization plate 500 and the locking structure. The three-dimensional constraint ensures that the connecting portion 100 is securely locked within the connecting seat 200.

[0056] In particular, the overlapping arrangement of the first locking surface 207 and the second locking surface 303 forms a self-locking effect. When subjected to external force, this structure will become increasingly tighter, greatly improving the security of the connection.

[0057] When disassembly is required, the user simply presses the upper surface of the adjusting part 300 to overcome the elastic force of the driving member 400, causing the adjusting part 300 to return from the locked position to the free position along the second direction. At this time, the first locking surface 207 and the second locking surface 303 are no longer overlapping, until the second guide surface 302 is lower than the first guide surface 206 in the second direction. The user then pushes the adjusting part 300 to slide it away from the locking section 202, and the adjusting part 300 enters the free position. The connecting part 100 moves with the adjusting part 300 along the first direction to disengage from the locking section 202, and is then pulled out along the second direction, completing the disassembly operation.
