Abstract
Description
Technical Field
[0001] This application relates to the field of mechanical connection structure technology, and further to a snap-fit structure. Background Technology
[0002] Existing latching structures typically consist of an operating part and a latch. In this type of structure, the movements of the operating part and the latch are completely synchronized. That is, when an operating force is applied to the operating part to pull it open, the latch will immediately move to the corresponding position in sync with the operating part; and when the operating part is retracted, the latch will also return to its initial state in sync with the operating part.
[0003] Because the movement of the operating part and the latch is completely synchronized, their travel distances when pulling open or retracting are relatively short. This directly results in extremely limited time available to the user during operation, making the latch structure more difficult to operate and potentially leading to operational failure. Utility Model Content
[0004] To address the aforementioned technical problems, the purpose of this application is to provide a snap-fit structure that can solve the problems of short stroke and insufficient operation time caused by the complete synchronization of the operating part and snap-fit movement in the prior art.
[0005] To achieve the above objectives, this application provides a snap-fit structure, comprising:
[0006] Base;
[0007] An operating unit is used to operate the state transition of the latching structure;
[0008] A snap-fit component is movably connected to the base and cooperates with the operating part;
[0009] A stroke control component is disposed between the operating part and the latching member to control the relative movement of the two during operation;
[0010] In the first state, the operating part drives the latching member to move to the first stop position defined by the stroke control component. After that, the operating part can continue to move, and the latching member remains stationary, which is suitable for taking out the object to be locked.
[0011] In the second state, the latching member remains stationary until the operating part reaches the second trigger position defined by the travel control component. When the operating part exceeds the second trigger position, the latching member moves with the operating part to lock the object to be locked.
[0012] In some embodiments, the stroke control component includes an adapter disposed between the operating part and the latching member, and respectively cooperating with the operating part and the latching member, so as to drive the latching member to move through the adapter when the operating part moves.
[0013] In some embodiments, the adapter has at least one first snap-fit end, and the operating part has at least one second snap-fit end, the first snap-fit end and the second snap-fit end snapping into each other, thereby fixing the positions of the operating part and the adapter relatively.
[0014] And / or, the adapter further has at least one first abutting end face, and the latching member has at least one second abutting end face. During the movement of the operating part, the first abutting end face and the second abutting end face can abut against each other so as to transmit the power of the operating part to the latching member through the adapter, thereby causing the latching member to move with the operating part.
[0015] In some embodiments, the contours of both the adapter and the latching member on one side of their contact surfaces are arc-shaped, and converge toward the central axis of the entire latching structure along the unlocking direction of the latching structure.
[0016] In some embodiments, the stroke control component further includes a positioning structure, which includes a first positioning structure disposed on the adapter, a second positioning structure disposed on the latching member, and a third positioning structure disposed on the base;
[0017] The first positioning structure matches the third positioning structure and is used to guide and position the movement trajectory of the adapter. The second positioning structure matches the third positioning structure and is used to guide and position the movement trajectory of the buckle.
[0018] In some embodiments, the first positioning structure includes a plurality of first sliding grooves disposed on the adapter, and the second positioning structure includes a plurality of second sliding grooves disposed on the buckle.
[0019] The third positioning structure includes a plurality of positioning protrusions disposed on the base; the positioning protrusions include a first protrusion and a second protrusion, the first protrusion being slidably engaged with the first sliding groove, and the second protrusion being slidably engaged with the second sliding groove;
[0020] When the latching member moves in the first direction, the second protrusion moves from one end of the second sliding groove to the other end, forming the first stop position.
[0021] In some embodiments, the first sliding groove has a two-section structure, one section being a straight section and the other section being an oblique section. The straight section and the oblique section are connected. When the adapter moves the buckle in the first direction, the first protrusion first moves along the straight section until the position of the buckle is locked. Then the first protrusion moves from the straight section to the oblique section to guide the movement of the adapter through the oblique section.
[0022] And / or, the second protrusions are arranged at corresponding straight intervals, and the second sliding groove is linear, so that the fastener can move in a straight line.
[0023] In some embodiments, the latching member includes a first latch and a second latch, and the stroke control component is disposed between the first latch and the operating part, wherein the first latch can move under the drive of the operating part;
[0024] The first and second latches are connected by a synchronous structure to achieve synchronous movement of the first and second latches, thereby simultaneously locking the object to be locked by the first and second latches.
[0025] In some embodiments, the synchronization structure includes a rotating member and a recessed portion disposed on the first buckle. The middle part of the rotating member is rotatably connected to the base, such that both ends of the rotating member are in a free state. One end of the rotating member is embedded in the recessed portion, and the other end abuts against the second buckle.
[0026] When the first buckle moves, the rotating component rotates synchronously under force, causing the other end of the rotating component to push the second buckle so that it moves synchronously with the first buckle.
[0027] In some embodiments, the snap-fit structure further includes multiple elastic elements;
[0028] The operating part is movably connected to the base through the elastic element, thereby enabling the operating part to be reset by the rebound force generated by the elastic element when no external force is applied.
[0029] The fastener is movably connected to the base via the elastic element, thereby enabling the fastener to reset by the rebound force generated by the elastic element when no external force is applied.
[0030] Compared with existing technologies, the snap-fit structure provided in this application has the following advantages: Through the stroke control component, the movement of the operating part and the snap-fit component is asynchronous. In use, after the operating part drives the snap-fit component to the first stop position, it can continue its long stroke movement, while the snap-fit component remains stationary. This provides the user with ample operating time and space to retrieve the item to be locked, avoiding the problem of difficulty in retrieving items due to short operating time, as seen with traditional snap-fit systems.

[0045] In mechanical connections, electronic equipment assembly, household goods, and various industrial products, snap-fit structures have become a common method for quickly connecting and separating components due to their convenient installation and rapid disassembly. Traditional snap-fit structures generally consist of an operating part and a snap-fit mechanism. The operating part triggers the locking and unlocking action of the snap-fit, while the snap-fit is responsible for securing and releasing the connected components.
[0046] Currently, most common snap-fit structures on the market adopt a design where the movement of the operating part and the snap-fit are completely synchronized. The principle behind this synchronized movement structure is that the operating part and the snap-fit are connected by a simple rigid connection or a direct transmission mechanism. When a pulling or pushing force is applied to the operating part, the displacement of the operating part is immediately and equally transmitted to the snap-fit, causing it to produce a corresponding displacement synchronously.
[0047] However, this design reveals significant limitations in practical applications. Because the movement of the operating part and the latch are completely synchronized, their travel distances during opening and closing are relatively short. In real-world scenarios, this short travel distance means that the user has extremely limited time to complete the desired operation (such as removing or installing a locked item).
[0048] Taking battery replacement in electronic devices as an example, when the battery needs to be removed, the user pulls open the control unit to unlock the latch. Because the control unit and the latch move synchronously with a short stroke, the user must remove the battery from the device in a very short time. If the user's action is slightly delayed, the latch will immediately retract synchronously with the control unit the moment the control unit is released, locking the battery again and preventing it from being removed smoothly. This not only reduces operational efficiency but may also damage the battery or device interface due to repeated attempts.
[0049] To address the problems in the prior art, please refer to the appendix to the instruction manual. Figure 1 The snap-fit structure provided in this application can provide more operating time and space, and improve the stability and reliability of the entire snap-fit structure.
[0050] Reference manual attached Figure 1 This application provides a latching structure, including a base 1, an operating part 2, a latching element 3, and a stroke control component. The base 1 is the fundamental support component of the entire latching structure, providing a basic platform for the installation and movement of other components. The operating part 2, directly operated by the user, primarily controls the transition of the latching structure between different states, enabling the locking and unlocking of the object to be locked. The latching element 3 is movably connected to the base 1 and cooperates with the operating part 2, generating corresponding movements under the drive of the operating part 2 to complete the locking or unlocking action of the object to be locked. The stroke control component is disposed between the operating part 2 and the latching element 3, used to control the relative movement of the two during operation.
[0051] Specifically, please refer to the attached instruction manual. Figures 1 to 3When the user needs to retrieve the item to be locked, an external force is applied to the operating unit 2 to initiate its movement. (Corresponding to the first state described above) During its movement, the operating unit 2 will drive the cooperating latch 3 to move as well. The travel control component limits the travel distance of the latch 3. When the latch 3 reaches the first stop position defined by the travel control component, the travel control component will prevent the latch 3 from continuing to follow the operating unit 2, at which point the latch 3 remains stationary. The operating unit 2, however, is not subject to this restriction and can continue to move in the direction of the external force applied by the user. This design allows the operating unit 2 to travel a relatively long distance, providing the user with more time and space to complete the retrieval of the item.
[0052] For example, when using this snap-fit structure to secure a battery in an electronic device, the user pulls open the operating part 2, and after the snap-fit part 3 reaches the first stop position, the operating part 2 continues to move, allowing the user to easily remove the battery from the device without worrying that the battery will be stuck again due to insufficient operating time.
[0053] When it is necessary to lock the object, the user reverses the operation of the operating unit 2, moving it back to the initial position (corresponding to the second state described above). Before the operating unit 2 reaches the second trigger position defined by the travel control component, the travel control component keeps the latch 3 stationary, which facilitates the user's adjustment of the object's position. When the operating unit 2 exceeds the second trigger position, the travel control component releases the restriction on the latch 3, allowing the latch 3 to move with the operating unit 2 until the locking action of the object is completed. For example, when installing the battery of the aforementioned electronic device, the user first places the battery in a suitable position, then pushes the operating unit 2. Before the operating unit 2 reaches the second trigger position, the latch 3 remains stationary, allowing the user to fine-tune the battery position; when the operating unit 2 exceeds the second trigger position, the latch 3 moves with the operating unit 2 and securely locks the battery.
[0054] Understandably, the stroke control component in this embodiment achieves asynchronous movement between the operating unit 2 and the latching member 3, providing users with a longer operating stroke and more ample operating time. When picking up or installing objects to be locked, users no longer need to complete precise operating actions in a short time, greatly reducing the difficulty of operation and improving the success rate.
[0055] Furthermore, this snap-fit structure offers excellent ease of operation, making it applicable to a wider range of fields and scenarios. For example, it can be used in aerospace equipment, precision instruments, electronic devices, and household goods to achieve rapid connection and disconnection of components.
[0056] Optionally, in some embodiments, an anti-slip texture or handle may be provided on the operating part 2 to improve the comfort and stability of user operation; or, a cushioning material may be provided on the buckle 3 to reduce damage to the object to be locked.
[0057] In this embodiment, the stroke control component can be implemented using various structural forms. For example, it can be designed as a combination of a limiting groove and a slider. Sliders are respectively provided on the operating part 2 and the latching member 3, and corresponding limiting grooves are provided on the base 1. The shape and length of the limiting grooves are designed according to the first stop position and the second trigger position. When the operating part 2 moves, the slider connected to it slides within the limiting groove, driving the latching member 3 to move. When the slider on the latching member 3 reaches the position corresponding to the first stop position in the limiting groove, the slider is blocked by the limiting groove, the latching member 3 stops moving, and the slider on the operating part 2 can continue to slide within its corresponding limiting groove. In reverse operation, when the slider on the operating part 2 reaches the position corresponding to the second trigger position in the limiting groove, the restriction on the slider on the latching member 3 is released by a mechanical mechanism, allowing it to move together with the operating part 2.
[0058] In one embodiment, based on the above embodiments, the stroke control component includes an adapter 41, which is disposed between the operating part 2 and the fastener 3, and is connected to the operating part 2 and the fastener 3 respectively, to ensure that the movement of the operating part 2 can be transmitted to the fastener 3 through the adapter 41, thereby realizing the control of the state transition of the fastener structure.
[0059] Understandably, the adapter 41 makes the motion transmission between the operating part 2 and the latching part 3 more precise. In actual use, the adapter 41 can appropriately convert and adjust the motion of the operating part 2 to ensure that the latching part 3 can move according to the predetermined stroke and method, better adapt to different operating forces and motion directions, and improve the operating accuracy of the latching structure.
[0060] Furthermore, the adapter 41 can be of different types, and can be selected and designed according to actual application scenarios and needs, enabling the snap-fit structure to adapt to various complex working environments and operational requirements. On the other hand, the existence of the adapter 41 can, to some extent, reduce the design and manufacturing requirements of the operating part 2 and the snap-fit 3 itself. The movement of the operating part 2 can be buffered and adjusted by the adapter 41, reducing the direct impact on the snap-fit 3, thereby extending the service life of the snap-fit 3.
[0061] The "first stop position" is set by the stroke control component according to the function and the need to pick up the object. It is defined by mechanical limit devices (such as limit blocks or limit grooves). When the buckle 3 reaches this position, it stops, and the operating part 2 can continue to move to facilitate picking up the object. Similarly, the "second trigger position" is also a preset key position used to determine the locking time of the object to be locked. When the operating part 2 has not reached this position, the adapter 41 and the buckle 3 are separated, and the buckle 3 is stationary, which makes it easy to adjust the position of the object to be locked. When the position is exceeded, the adapter 41 and the buckle 3 can be combined and drive the buckle 3 to lock the object to be locked.
[0062] Furthermore, the latching structure includes multiple elastic elements 5, which connect the operating part 2 to the base 1 and the latching element 3 to the base 1, respectively, providing a reset function for the operating part 2 and the latching element 3. Throughout the operation of the latching structure, the elastic elements 5 play a crucial auxiliary role, enabling the operating part 2 and the latching element 3 to automatically return to their initial positions after completing a specific action.
[0063] Specifically, the operating part 2 is movably connected to the base 1 via an elastic element 5. One end of the elastic element 5 is fixed to the operating part 2, and the other end is fixed to the base 1, allowing the operating part 2 to move relative to the base 1 when subjected to force. Simultaneously, the elastic element 5 deforms as the operating part 2 moves. When the user applies external force to the operating part 2, the operating part 2 overcomes the elastic force of the elastic element 5 and displaces, thereby driving the adapter 41, the latching element 3, and other components to move, thus unlocking the latching structure. Once the external force disappears, the elastic element 5, due to its elastic properties, generates a restoring force, pulling the operating part 2 back to its initial position, ultimately resetting the operating part 2.
[0064] The latching element 3 is also movably connected to the base 1 via the elastic element 5. The installation method of the elastic element 5 is similar to that of the operating unit 2, with one end connected to the latching element 3 and the other end connected to the base 1. Driven by the operating unit 2, the latching element 3 moves to lock or unlock the object. For example, during unlocking, the elastic element 5 is stretched, causing the latching element 3 to open and allowing the item to be removed. Simultaneously, if another item needs to be locked, it can be placed in a preset position. When the external force disappears, the rebound force generated by the elastic element 5 will push the latching element 3 back to its original position, thus locking the item again.
[0065] In one embodiment, such as Figure 4 and Figure 5 As shown, the adapter 41 has at least one first snap-fit end 411, and the operating part 2 has at least one second snap-fit end 211. The first snap-fit end 411 and the second snap-fit end 211 snap into each other, thereby fixing the positions of the operating part 2 and the adapter 41 relatively, and ensuring that the movement of the operating part 2 can be accurately transmitted to the adapter 41.
[0066] Optionally, as shown in the figure, the first snap-fit end 411 can be designed as a protruding structure, and the second snap-fit end 211 can be designed as a matching recessed structure. The shapes of the protrusion and recess can be designed according to actual needs, such as circular, square, trapezoidal, etc. When the operating part 2 and the adapter 41 are installed, the protrusion is embedded in the recess, realizing the snap-fit between the two. This snap-fit method improves stability in multiple directions and ensures that the operating part 2 and the adapter 41 are relatively fixed in position during movement.
[0067] Furthermore, one of the first latching end 411 and the second latching end 211 can be designed as a flexible latching claw structure, while the other can be designed as a latching groove structure. When the operating part 2 and the adapter 41 are latched together, the latching claw deforms under elastic action and engages in the latching groove, thus achieving the connection between the two. The flexible latching claw can reduce the impact force during operation and extend the service life of the latching end. Moreover, the flexible latching is relatively easy to disassemble; it can be separated simply by applying a certain external force to deform the latching claw.
[0068] It should be noted that when the adapter 41 and operating part 2 are small, a relatively small number of snap-fit ends can be provided. This is because space is limited in small-sized structures, and too many snap-fit ends may lead to an overly complex structure, increasing manufacturing difficulty and cost. For larger adapter 41 and operating part 2, multiple snap-fit ends can be provided to ensure that the entire structure is tightly connected in all parts, avoiding loosening of the connection due to uneven local stress.
[0069] In one embodiment, such as Figure 5 and Figure 6 As shown, in addition to the snap-fit end connected to the operating part 2, the adapter 41 also has at least one first abutting end face 410; the latching member 3 has at least one second abutting end face 310. These two abutting end faces can abut against each other during the movement of the operating part 2, so as to transmit the power of the operating part 2 to the latching member 3 through the adapter 41, thereby causing the latching member 3 to move with the operating part 2.
[0070] Specifically, when the first abutting end face 410 and the second abutting end face 310 are separated, or when the movement of the latching member 3 is restricted, the movement of the adapter 41 will not move the latching member 3, and the latching member 3 remains stationary. This provides convenience for the user to adjust the position of the object to be locked. The user can place the object to be locked in the accurate position at this stage to ensure the accuracy of subsequent locking operations. When the first abutting end face 410 of the adapter 41 abuts against the second abutting end face 310 of the latching member 3, the adapter 41 can transmit the power of the operating part 2 to the latching member 3, causing the latching member 3 to move together with the operating part 2 to complete the locking action of the object to be locked.
[0071] In this embodiment, the contact between the first contact end face 410 and the second contact end face 310 can be a direct planar contact, in which the two planes can make contact over a large area to ensure the stability of power transmission; or it can be a flexible contact achieved through some buffer structures (such as rubber pads) to reduce impact and noise.
[0072] As shown in the figure, the contours of the adapter 41 and the buckle 3 on the contact surface side are both designed as arcs, and they converge toward the central axis of the buckle structure along the unlocking direction of the buckle structure.
[0073] It should be noted that the curved and tapered contour provides a clear guide for the displacement of the adapter 41. When the operating part 2 drives the adapter 41 to move, it can guide the adapter 41 to move along a specific path, avoiding malfunctions caused by displacement deviation.
[0074] Furthermore, when the adapter 41 moves independently, its converging contour allows it to move as far away from the latching member 3 as possible. As shown in the figure, during the unlocking process (the operating part 2 moves in the direction of the arrow), the adapter 41 converges towards the central axis along the arc-shaped contour. This gradually increases the lateral distance between the adapter 41 and the latching member 3, providing a larger safety space for both and greatly reducing the possibility of collision between them.
[0075] In one embodiment, the stroke control component includes a positioning structure, specifically including a first positioning structure disposed on the adapter 41, a second positioning structure disposed on the latching member 3, and a third positioning structure disposed on the base 1.
[0076] The first positioning structure is set on the adapter 41, and the third positioning structure is set on the base 1. The two are matched with each other to achieve the guiding positioning of the movement trajectory of the adapter 41.
[0077] During the movement of the adapter 41 driven by the operating unit 2, the cooperation between the first positioning structure and the third positioning structure is similar to that of a track and a slider. For example, the first positioning structure can be designed as a raised guide rail, while the third positioning structure is a corresponding grooved track. When the adapter 41 begins to move under the drive of the operating unit 2, the guide rail of the first positioning structure slides along the grooved track of the third positioning structure. The shape and orientation of the grooved track determine the movement trajectory of the adapter 41. This cooperation method can effectively limit the displacement of the adapter 41 in unnecessary directions, ensuring that it can only move along a predetermined trajectory.
[0078] In the first state (retrieving the object to be locked), the operating unit 2 drives the adapter 41 to move, and the first positioning structure slides along the track of the third positioning structure, ensuring that the adapter 41 can accurately drive the latch 3 to the first stop position. Afterwards, as the operating unit 2 continues to move, the adapter 41 remains stable under the guidance of the first and third positioning structures, without shaking or shifting, providing a stable operating environment for the user.
[0079] The second positioning structure is set on the buckle 3, and it also matches the third positioning structure on the base 1, and is used to guide and position the movement trajectory of the buckle 3.
[0080] The cooperation principle of the second and third positioning structures is similar to that of the first and third positioning structures. When the fastener 3 needs to move, the guide rail of the second positioning structure slides on the grooved track of the third positioning structure. At this time, the design of the grooved track determines the direction and stroke of the fastener 3.
[0081] In the second state (locking the object to be locked), when the operating part 2 exceeds the second trigger position and drives the latching member 3 to move, the second positioning structure moves along the track of the third positioning structure, ensuring that the latching member 3 can accurately reach the locking position and achieve reliable locking of the object to be locked. This guiding and positioning function can prevent problems such as jamming or misalignment of the latching member 3 during movement, improving the accuracy and stability of locking.
[0082] Based on the above, such as Figure 2 and Figure 3 As shown, the first positioning structure includes multiple first sliding grooves 412 located on the adapter 41, the second positioning structure includes multiple second sliding grooves 312 disposed on the fastener 3, and the third positioning structure includes multiple positioning protrusions 11 disposed on the base 1, the positioning protrusions 11 being further divided into first protrusions 111 and second protrusions 112. The first protrusions 111 are slidably engaged with the first sliding grooves 412, and the second protrusions 112 are slidably engaged with the second sliding grooves 312. Through this sliding engagement, precise guidance and positioning of the movement of the adapter 41 and the fastener 3 are achieved.
[0083] Understandably, the first positioning structure has multiple first sliding grooves 412 on the adapter 41, and the third positioning structure has a first protrusion 111 on the base 1. When the operating part 2 moves the adapter 41, the first protrusion 111 slides within the first sliding groove 412. The shape, length, and orientation of the first sliding groove 412 determine the movement trajectory of the adapter 41 and limit the relative movement range between the adapter 41 and the base 1. For example, if the first sliding groove 412 is straight, the adapter 41 will move along a straight trajectory; if it is curved, the adapter 41 will move along a curved trajectory, thus limiting the movement of the adapter 41 to the range defined by the first sliding groove 412, ensuring the stability and accuracy of the movement of the adapter 41.
[0084] Similarly, multiple second sliding grooves 312 of the second positioning structure are provided on the fastener 3, and the second protrusion 112 of the third positioning structure is provided on the base 1. When the fastener 3 moves, the second protrusion 112 slides within the second sliding groove 312. Likewise, the design of the second sliding groove 312 determines the movement trajectory of the fastener 3. This matching method allows for precise control of the movement of the fastener 3, preventing it from shifting or wobbling during movement.
[0085] For example, in the first direction of the fastener 3 (attached) Figure 2 When the second protrusion 112 moves relative to the second sliding groove 312 (in the direction indicated by the middle arrow), the two ends of the second sliding groove 312 define the range of movement of the second protrusion 112, that is, the range of relative movement between the latching part and the base 1. When the second protrusion 112 moves relative to the other end of the second sliding groove 312, a first stop position is formed. At this position, the latching member 3 stops moving, while the operating part 2 can continue to move. For example, in a scenario where it is necessary to remove the object to be locked, the operating part 2 drives the latching member 3 to move. When the second protrusion 112 reaches the end of the second sliding groove 312, the latching member 3 stops, providing the user with sufficient time and space to remove the object to be locked.
[0086] In one embodiment, please refer to the appendix to the instruction manual. Figure 5 The first sliding groove 412 has a two-section structure, one section is a straight section 4121 and the other section is an oblique section 4122. The straight section 4121 and the oblique section 4122 are connected. When the operating part 2 drives the adapter 41 and then drives the buckle 3 to move in the first direction, the movement process of the first protrusion 111 in the first sliding groove 412 is divided into two stages.
[0087] In the initial stage of movement, the first protrusion 111 moves along the straight segment 4121 of the first sliding groove 412. During this process, the design of the straight segment 4121 enables the adapter 41 and the latching member 3 to move relatively smoothly and in a clear direction. Due to the guidance of the straight segment 4121, the latching member 3 will move to a specific position according to a predetermined path, and when the first protrusion 111 moves to a specific point of the straight segment 4121 (generally the junction of the straight segment 4121 and the diagonal segment 4122), the position of the latching member 3 is locked.
[0088] Once the latching element 3 is locked in place, the first protrusion 111 begins to move from the straight segment 4121 to the inclined segment 4122. The inclined segment 4122 further guides the movement of the adapter 41 and causes a change in direction during its movement. This change can be adjusted according to actual needs to meet different operational requirements. For example, in cases where the adapter 41 needs to be offset at a specific angle, the inclined segment 4122 can guide the adapter 41 to complete the corresponding action along a predetermined trajectory.
[0089] It should also be noted that the first sliding groove 412 in this embodiment and the adapter 41 with an arc-shaped profile mentioned above can cooperate with each other to effectively utilize space, avoid interference with surrounding components, and further improve the performance of the entire snap-fit structure.
[0090] In one embodiment, the second protrusions 112 are arranged at corresponding linear intervals, while the second sliding groove 312 is linear. When the operating part 2 drives the adapter 41, and then drives the buckle 3 to move through the adapter 41, the second protrusions 112 will slide relative to each other within the second sliding groove 312. Since the second protrusions 112 are arranged at linear intervals and the second sliding groove 312 is linear, the buckle 3 can only move along a straight line. This linear movement is simple and clear, giving the buckle 3 a high degree of directionality and controllability during movement.
[0091] It is also understandable that, in the snap-fit structure, the positioning protrusion 11 on the base 1 plays a crucial role in the movement trajectory and positioning of the adapter 41 and the snap-fit 3. The adapter 41 and the snap-fit 3 vary in form, and their shape, size, and movement method all affect the setting of the positioning protrusion 11. To ensure that the adapter 41 and the snap-fit 3 can move accurately according to the design requirements and achieve the corresponding functions, it is necessary to make targeted adjustments to the positioning protrusion 11 according to their specific forms, thereby ensuring the stable and efficient operation of the entire snap-fit structure.
[0092] According to the attached diagram, the fastener 3 has a U-shaped symmetrical structure. At this time, the positioning protrusion 11 is symmetrically arranged along the center line of the U-shaped structure, so that the adapter 41 and the fastener 3 have good balance and stability during movement.
[0093] Based on the above embodiments, in one embodiment, such as Figure 1 As shown, the latching component 3 includes a first latch 301 and a second latch 302. A stroke control component is disposed between the first latch 301 and the operating part 2. By controlling the operating part 2, the first latch 301 can be moved. At the same time, the first latch 301 and the second latch 302 are connected by a synchronization structure to achieve synchronous movement, thereby locking the object to be locked simultaneously through these two latches.
[0094] In this embodiment, the operating unit 2 serves as a power source. After the user applies an operating force to it, the movement of the operating unit 2 is transmitted to the first latch 301 through the stroke control component. The stroke control component regulates the movement stroke of the first latch 301 (as described above, it will not be repeated here), ensuring that the first latch 301 accurately reaches the predetermined position. When the first latch 301 moves under the drive of the operating unit 2, the synchronization structure can drive the second latch 302 to move synchronously. Thus, when the user operates the operating unit 2, they only need to perform one operation to control the movement of both latches simultaneously, without having to operate the two latches separately.
[0095] In addition, such as Figure 1 As shown, in this buckle structure, the first buckle 301 and the second buckle 302 are each equipped with two hooks. The four hooks apply force from different positions, which can more evenly distribute the external force on the object to be locked, effectively prevent the object to be locked from moving or shaking in all directions, and at the same time, can more accurately position the object to be locked.
[0096] In one embodiment, such as Figure 1 and Figure 6 As shown, the synchronization structure includes a rotating member 6 and a recess 3010 disposed on the first latch 301. The middle part of the rotating member 6 is rotatably connected to the base 1. This design allows both ends of the rotating member 6 to move freely. One end is embedded in the recess 3010 of the first latch 301, and the other end abuts against the second latch 302. When the first latch 301 moves under the drive of the operating part 2, the synchronization structure can transmit the motion to the second latch 302.
[0097] Specifically, when the first latch 301 begins to move, since one end of the rotating member 6 is embedded in the recess 3010 of the first latch 301, the movement of the first latch 301 will exert a force on the rotating member 6, causing the rotating member 6 to be subjected to force and rotate synchronously around its central rotation point on the base 1. This rotation of the rotating member 6 is like a lever, with the central rotation point as the fulcrum, one end is driven by the recess 3010, and the other end generates corresponding displacement and thrust as it rotates.
[0098] After the rotating component 6 rotates, the end of it that abuts against the second latch 302 will push the second latch 302 accordingly, causing the second latch 302 to start moving, thereby realizing the synchronous movement of the first latch 301 and the second latch 302. Throughout the process, the rotating component 6 plays a key role in motion transmission and conversion, converting the linear motion of the first latch 301 into a push on the second latch 302, thereby driving the second latch 302 to move synchronously.
[0099] Understandably, this synchronization structure design is simple, achieving synchronized movement of the first latch 301 and the second latch 302 solely through the cooperation of the rotating part 6 and the recessed part 3010. Compared to some complex synchronization mechanisms, such as gear transmission and chain transmission, it reduces the number of parts, lowers the complexity of the structure, and also reduces potential failure points caused by too many parts, thus improving the reliability and efficiency of synchronized movement.
[0100] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
