Description

[0001] This application claims priority to Chinese Patent Application No. 202323132354.5, filed on November 21, 2023, with the Chinese Patent Office, entitled “A Quick-Release Component and Wearable Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of quick-release technology, and further to a quick-release component and wearable device. Background Technology

[0003] Currently, in order to improve the portability and durability of wearable devices, they are equipped with fasteners such as straps, watch straps, or backpack straps. However, most of these fasteners are fixed to the wearable device, making it difficult for users to disassemble or replace them when they become dirty or damaged, which causes inconvenience to users. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to provide a quick-release component and wearable device, which can achieve relative fixation or unlocking between the main body of the device and the fixing parts through simple rotation, greatly improving the convenience of operation, and making it less prone to accidental contact and more reliable.

[0005] To achieve the above objectives, this utility model provides a quick-release component for use in wearable devices. The wearable device includes a device body and a fixing member. The quick-release component is configured to detachably connect the device body to the fixing member. The quick-release component includes:

[0006] The quick-release mechanism includes a rotating body and a main shaft. The main shaft is movably connected to the main body of the equipment or a fixed component. The rotating body is sleeved on the outer periphery of the main shaft and can rotate relative to the main shaft. The main shaft has a first mating surface and a second mating surface.

[0007] The rotating body has a cavity for accommodating a fixing pin. The fixing pin and the rotating body are connected by an elastic element so that the fixing pin presses against the main shaft by the elastic force of the elastic element. The rotating body is provided with a through hole that mates with the fixing pin. The fixing pin has a third mating surface and a fourth mating surface.

[0008] When the rotating body rotates relative to the main shaft to the first preset position, the first mating surface abuts against the third mating surface, and at least a portion of the fixing pins extend through the through hole in a direction away from the main shaft to install the fixing component or the main body of the equipment.

[0009] When the rotating body rotates relative to the main shaft to the second preset position, the second mating surface abuts against the fourth mating surface, and the fixing pin retracts through the through hole toward the main shaft to remove the fixing component or the main body of the equipment.

[0010] It's worth noting that the fasteners can be installed and removed by adjusting the extension or retraction of the retaining pin through the relative rotation of the rotating body and the main shaft. This is beneficial for user operation, making it more convenient and less prone to errors when operating with one hand. Furthermore, this quick-release mechanism has few limitations and can be used on many devices, offering strong adaptability. Additionally, the fasteners can be detached from the main body of the equipment without the need for additional buttons, reducing material usage and improving the overall aesthetic consistency of the equipment.

[0011] It is understood that quick-release components can be installed on the main body of the device or on the fasteners, and this application does not specifically limit this.

[0012] In some embodiments, a limiting end is provided at the end of the spindle away from the fixing pin, and a limiting hole is provided on the main body of the device or the fixing component. The limiting end is connected to the limiting hole to prevent the spindle from rotating circumferentially.

[0013] Understandably, the retaining pin extends and retracts by rotating the main body relative to the spindle. If the spindle is rotatable, it will rotate synchronously when the main body rotates, making it difficult to change the relative position of the spindle and the retaining pin, which can easily affect normal assembly and disassembly functions.

[0014] In some embodiments, the limiting end has a first plane, and the inner wall surface of the limiting hole has a second plane. The first plane and the second plane are arranged correspondingly to prevent the spindle from rotating circumferentially.

[0015] It is understandable that the limiting end on the spindle has a first plane, and the inner wall of the limiting hole has a second plane. The first plane and the second plane are set in correspondence to limit the spindle, thereby preventing the spindle from rotating circumferentially. When the rotating body rotates relative to the spindle, the spindle will not rotate, but the rotating body will rotate relative to the spindle, so that the relative positional relationship between the rotating body and the fixed pin changes, thereby realizing the assembly and disassembly function of the quick-release component.

[0016] In some embodiments, the first mating surface and the second mating surface are arranged adjacent to each other, and the second mating surface is set as an inclined surface, so that the end of the main shaft away from the equipment body or the fixing component has a trapezoidal profile; the first mating surface, the second mating surface and the third mating surface and the fourth mating surface are arranged correspondingly.

[0017] Here, the end of the spindle has a trapezoidal profile, and the fixing pin is also set to correspond to the trapezoidal profile. The trapezoidal profiles of both provide a certain displacement space for the extension and retraction of the fixing pin. When the user rotates the main body, the mating surface moves from the inclined surface to the straight surface or from the straight surface to the inclined surface, which naturally causes the fixing pin to extend or retract. Moreover, the inclined surface can also play a guiding role, making the extension and retraction of the fixing pin more stable.

[0018] In some embodiments, the number of retaining pins is at least two;

[0019] Furthermore, the second mating surface rotates along the axial direction of the main shaft to form a conical surface, so that when the rotating body rotates relative to the main shaft to the second preset position, each of the fourth mating surfaces can be mated with the conical surface.

[0020] Understandably, the conical surface formed by the second mating surface on the main shaft enables the main shaft to achieve circumferential mating, providing a basis for adding fixing pins. Operators or technicians can adjust the number of fixing pins or the shape of the rotating body according to specific needs, so that the quick-release mechanism has stronger fixing ability and adapts to the diverse needs of different equipment and fasteners during loading and unloading.

[0021] In some embodiments, the end of the spindle on the side of the trapezoidal profile is configured as a dial;

[0022] A baffle ring is also provided on the outer periphery of the main shaft. The inclined surface faces closer to the baffle ring, and there is a gap between the baffle ring and the dial head. When the rotating body rotates relative to the main shaft to the second preset position, part of the fixing pin is limited between the baffle ring and the dial head.

[0023] The spacer ring provides a certain amount of space for the fixing pin. When the fixing pin retracts inward, it can be locked between the spacer ring and the dial, making it less likely for the fixing pin to wobble and preventing collisions between the internal structures of the quick-release assembly.

[0024] Furthermore, the lever and main dial can be connected by threads, keys, or pins to form the aforementioned spindle. The main dial includes the aforementioned dial and a spacer ring, facilitating subsequent assembly. Alternatively, the lever and main dial can be integrally molded.

[0025] In some embodiments, the outer periphery of the spindle is further provided with a protrusion, the rotating body extends along the axial direction of the spindle to form a hollow sleeve, the hollow sleeve is connected to the accommodating cavity, and the inner periphery of the hollow sleeve is provided with a track that is opposite to the protrusion.

[0026] The track has a closed loop structure with the ends connected, and there is a height difference between the highest and lowest points of the track. When the rotating body rotates relative to the main shaft, the track and the protrusion slide relative to each other, so that the main shaft moves back and forth axially relative to the rotating body to adjust the relative position between the dial and the fixing pin.

[0027] It should be noted that by setting up the protrusion and the track, the main shaft can simultaneously reciprocate axially during the rotation of the rotating body relative to the main shaft, so the fixing pin can extend and retract during the translation. Moreover, since the track forms a closed loop, the fixing pin can freely extend or retract regardless of which direction the main body is turned, achieving stepless adjustment and thus improving the user experience.

[0028] In some embodiments, grooves that mate with the protrusions are provided at the highest and lowest points of the track, respectively. When the rotating body rotates relative to the main shaft to the first preset position or the second preset position, at least a portion of the protrusions are embedded in the corresponding grooves to prevent the protrusions from slipping.

[0029] The track features grooves at both its lowest and highest points. When the retaining pin retracts or extends, the protrusions can fit into the grooves, ensuring relative fixation between the protrusions and the track. This further enhances the reliability of the component and prevents slight slippage between the protrusions and the track in case of accidents, which could prevent the retaining pin from extending or retracting as expected.

[0030] In some embodiments, the groove includes two guide surfaces and a limiting surface connected to the two guide surfaces, the guide surfaces being inclined from the opening of the groove toward the limiting surface, so that the opening width of the groove gradually increases.

[0031] Understandably, since the protrusion is embedded in the groove, when the protrusion needs to enter the track, the two guide surfaces of the groove can effectively guide the protrusion to slide out of the groove and into the track, making it easy to assemble and disassemble the main body of the equipment and the fixing parts, thereby improving the user experience.

[0032] In some embodiments, a spring is fixed between the track and the spacer ring, and the spring is sleeved on the outer periphery of the main shaft;

[0033] When the rotating body rotates relative to the main shaft to the first preset position, the protrusion connects with the highest point of the track, and the spring is compressed to generate a rebound force to press the protrusion and the corresponding groove.

[0034] And / or,

[0035] When the rotating body rotates relative to the main shaft to the second preset position, the protrusion connects with the lowest point of the track, causing the spring to be stretched and generate a rebound force to press the dial and the fixing pin.

[0036] Understandably, a spring is installed between the track and the spacer ring, with the spring sleeved around the outer circumference of the main shaft. When the rotating body rotates relative to the main shaft to the first preset position, the spring is compressed, generating a rebound force that causes the protrusion to press against the corresponding groove, thereby enhancing the connection strength between the equipment body and the fixing component. Furthermore, when the rotating body rotates relative to the main shaft to the second preset position, the spring is stretched, generating a rebound force that allows the main shaft to return to the first preset position after reaching the second preset position, thus ensuring the continuous fixation of the equipment body and the fixing component.

[0037] In some embodiments, the fastener is provided with a snap-fit ​​hole, the outline of which matches the outline of the rotating body, so that the fastener can be sleeved onto the outer periphery of the rotating body through the snap-fit ​​hole;

[0038] Furthermore, a pin hole is provided on the wall of the snap-fit ​​hole. The outline of the pin hole matches the end outline of the fixing pin away from the main shaft, so that the fixing pin can be inserted into the pin hole to fix the fastener.

[0039] Understandably, the fastener is connected to the rotating body through a snap-fit ​​hole, and the outline of the pin hole matches the end of the fixing pin. When in use, the user puts the fastener on the outside of the rotating body, and the fastener will drive the rotating body to rotate, so as to simultaneously extend and retract the fixing pin, thereby allowing the fixing pin to be inserted into or retracted from the pin hole, thus realizing the installation and removal of the fastener.

[0040] In some embodiments, the end of the fixing pin away from the main shaft is provided with a limiting protrusion, which is configured to abut against the inner wall surface of the rotating body to limit the extension distance of the fixing pin when the fixing pin extends through the through hole in a direction away from the main shaft.

[0041] It is understandable that by setting a limiting protrusion, the extension length of the fixing pin relative to the rotating body can be limited, so that when disassembled, the fixing pin will not extend without restriction due to the action of the springs on both sides, which would make it difficult to insert the pin hole during assembly.

[0042] In another aspect, this utility model also provides a wearable device, which includes a wearable body and a wearing component, wherein the wearable body and the wearing component are detachably connected, and the wearable device further includes:

[0043] The above-mentioned quick-release component;

[0044] The wearable body serves as the main body of the device, the wearing piece serves as the fixing piece, and the quick-release mechanism is disposed on the wearable body to realize the assembly and disassembly between the wearable body and the wearing piece.

[0045] In some embodiments, when the quick-release mechanism is provided on the wearable body, the wearable part is provided with a snap-fit ​​hole for snapping with the rotating body, and the snap-fit ​​hole is provided with a pin hole, which is configured for inserting the fixing pin to fix the wearable part to the wearable body.

[0046] It is understandable that the wearing piece connects with the rotating body through a snap-fit ​​hole, and the outline of the pin hole matches the end of the fixing pin. When the user uses the wearing piece, he puts it on the rotating body, and the wearing piece drives the rotating body to rotate, so as to simultaneously extend and retract the fixing pin, thereby allowing the fixing pin to be inserted into or retracted from the pin hole, thus realizing the installation and removal of the wearing piece.

[0047] In some embodiments, the wearable device is provided with a metal retaining shell, which is configured to form the snap-fit ​​hole and the pin hole.

[0048] Understandably, this metal retaining shell prevents the wearable device from directly contacting the rotating body and causing wear during long-term installation and removal. This allows for easy replacement of the metal retaining shell during subsequent maintenance of the wearable device, thereby extending its lifespan and facilitating replacement and maintenance.

[0049] Compared with the prior art, the quick-release component and wearable device provided by this utility model have the following advantages:

[0050] 1. The quick-release component provided by this utility model adjusts the extension and retraction of the fixing pin by rotating the relative rotation between the main body and the main shaft, thereby realizing the installation and removal of the fixing part, which is more conducive to the user's operation and improves convenience. Moreover, this quick-release component is not easily restricted, has strong adaptability, and can be used in a variety of application scenarios.

[0051] 2. The quick-release component provided by this utility model provides a certain displacement space for the extension and retraction of the fixing pin through the trapezoidal contour design of the main shaft and the fixing pin. When the user rotates the main body, the mating surface moves from the inclined surface to the straight surface or from the straight surface to the inclined surface, which naturally causes the fixing pin to extend or retract.

[0052] 3. The quick-release component provided by this utility model has a protrusion on the main shaft and a track on the rotating body. This allows the relative position of the protrusion and the track to change during the rotation of the rotating body relative to the main shaft. The main shaft then performs axial reciprocating translation synchronously. Since the track forms a closed loop, the fixing pin can freely extend or retract regardless of the direction in which the rotating body is turned, achieving stepless adjustment.

[0053] 4. The quick-release component provided by this utility model has grooves at both the lowest and highest points of the track. When the fixing pin is retracted or extended, the protrusion can be embedded in the groove, thereby ensuring the relative fixation between the protrusion and the track and further improving the reliability of the component.

For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0070] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0071] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0072] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0073] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0074] In one embodiment, refer to the appendix to the specification. Figure 1 The present invention provides a quick-release component that can fix or disassemble the main body 1 and the fixing part 2 by simple twisting, which is conducive to convenient operation and has strong practicality.

[0075] Reference manual attached Figure 1 and Figure 2 The present invention provides a quick-release component, which is applied to a wearable device 11. The wearable device 11 includes a device body 1 and a fastener 2. The quick-release component is configured to allow the device body 1 and the fastener 2 to be detachably connected.

[0076] The quick-release assembly includes a quick-release mechanism 13, which includes a rotating body 3 and a main shaft 4. The main shaft 4 is movably connected to the equipment body 1 or the fixing part 2. The rotating body 3 is sleeved on the outer periphery of the main shaft 4 and can rotate relative to the main shaft 4. The main shaft 4 has a first mating surface 441 and a second mating surface 442.

[0077] The rotating body 3 has a cavity 33 for mounting a fixing pin 31. The fixing pin 31 and the rotating body 3 are connected by an elastic member 310 so that the fixing pin 31 presses the main shaft 4 by the elastic force of the elastic member 310. The rotating body 3 is provided with a through hole 32 that cooperates with the fixing pin 31. The fixing pin 31 has a third mating surface 443 and a fourth mating surface 444.

[0078] When the rotating body 3 rotates relative to the main shaft 4 to the first preset position, the first mating surface 441 abuts against the third mating surface 443, and at least a portion of the fixing pins 31 extend through the through holes 32 in a direction away from the main shaft 4 to mount the fixing member 2 or the equipment body 1. When the rotating body 3 rotates relative to the main shaft 4 to the second preset position, the second mating surface 442 abuts against the fourth mating surface 444, and the fixing pins 31 retract through the through holes 32 in a direction closer to the main shaft 4 to remove the fixing member 2 or the equipment body 1.

[0079] It should be noted that the first and second preset positions will be further explained later. In this embodiment, they are simply used to distinguish the relative rotational positions between the rotating body 3 and the main shaft 4, so as to further obtain the relative situation of their mating surfaces through their relative rotational positions. In addition, only the case of two fixing pins 31 is shown in the attached drawings, but in reality, one or more fixing pins 31 can be provided.

[0080] Understandably, the first mating surface 441, the second mating surface 442, the third mating surface 443, and the fourth mating surface 444 are only used to distinguish the working surfaces of the fixed pin 31 and the main shaft 4 when they abut against each other, and have no special meaning; while the elastic element 310 can be a spring, a wave washer, etc.

[0081] Moreover, in this embodiment, the installation and removal of the fixing part 2 is achieved by adjusting the extension or retraction of the fixing pin 31 through the relative rotation of the rotating body 3 and the main shaft 4. This is beneficial to the user's operation, making it more convenient for the user to operate with one hand and less prone to errors. In addition, this quick-release mechanism 13 has few limitations and can be applied to many devices, showing strong adaptability.

[0082] In addition, the fastener 2 can be detached from the main body 1 without the need for additional button structures, reducing material usage and improving the overall appearance consistency of the main body 1.

[0083] It is understood that the quick-release component can be installed on the main body 1 of the device or on the fastener 2, and this application does not make any specific limitation on this.

[0084] The following description uses the quick-release component as an example of the device body 1.

[0085] In one embodiment, such as Figure 3 and Figure 4 As shown, a limiting end 410 is provided at the end of the spindle 4 away from the fixed pin 31, and a limiting hole 100 is provided on the main body 1 of the equipment. The limiting end 410 is connected to the limiting hole 100 to prevent the spindle 4 from rotating circumferentially.

[0086] Understandably, the fixed pin 31 extends or retracts by rotating the main body 3 relative to the main shaft 4. If the main shaft 4 is rotatable, it will rotate synchronously when the main body 3 rotates. In this case, the relative positional relationship between the main shaft 4 and the fixed pin 31 will be difficult to change. That is to say, to achieve normal assembly and disassembly functions, the main shaft 4 needs to translate in the axial direction, rather than rotate in the circumferential direction.

[0087] It should also be noted that there are many ways in which the main shaft 4 is connected to the main body 1, or how the rotating body 3 rotates relative to the main shaft 4 and the main body 1, and these are not the inventive points of this utility model, so no specific limitation is made on them.

[0088] For example, if the spindle 4 needs to be movable relative to the main body 1, it can be connected between the two by a telescopic component, spring 5 or similar structure. If the rotating body 3 needs to rotate relative to the spindle 4 or relative to the main body 1, it can be achieved by a rotating bearing, threaded structure, etc. There are countless similar structures or components, but they will not affect the technical effect of this embodiment.

[0089] In one embodiment, the limiting end 410 has a first plane 411, and the inner wall surface of the limiting hole 100 has a second plane 101. The first plane 411 and the second plane 101 are correspondingly arranged to prevent the spindle 4 from rotating circumferentially.

[0090] It is understood that the limiting end 410 on the main spindle 4 has a first plane 411, and the inner wall surface of the limiting hole 100 has a second plane 101. The first plane 411 and the second plane 101 are correspondingly arranged, which can limit the circumferential movement of the main spindle 4, thereby preventing the main spindle 4 from rotating circumferentially. When the rotating body 3 rotates relative to the main spindle 4, the main spindle 4 will not rotate, but the rotating body 3 will rotate relative to the main spindle 4, so that the relative positional relationship between the rotating body 3 and the fixing pin 31 changes, thereby realizing the assembly and disassembly function of the quick-release assembly.

[0091] As can be seen from the accompanying drawings, in this embodiment, the limiting end 410 is similar to a semi-circular shape, and the limiting hole 100 is also a corresponding semi-circular shape. This is just one implementation. The shape and outline of the limiting end 410 and the limiting hole 100 can vary in many ways, as long as they can prevent circumferential rotation. For example, they can be rhomboid, rectangular or even polygonal. No further examples will be given here.

[0092] In one embodiment, such as Figure 2 As shown, the fastener 2 is provided with a snap-fit ​​hole 21. The outline of the snap-fit ​​hole 21 matches the outline of the rotating body 3, so that the fastener 2 can be sleeved on the outer periphery of the rotating body 3 through the snap-fit ​​hole 21.

[0093] Furthermore, a pin hole 200 is provided on the wall of the snap-fit ​​hole 21. The outline of the pin hole 200 matches the end outline of the fixing pin 31 away from the main shaft 4, so that the fixing pin 31 can be inserted into the pin hole 200 to fix the fixing member 2.

[0094] Understandably, the fastener 2 is connected to the rotating body 3 through the snap-fit ​​hole 21 provided on the fastener 2, and the outline of the pin hole 200 also matches the end of the fixing pin 31. When the user uses it, the fastener 2 is put on the outside of the rotating body 3, and the fastener 2 will drive the rotating body 3 to rotate, so as to simultaneously achieve the extension and retraction of the fixing pin 31, thereby allowing the fixing pin 31 to be inserted into the pin hole 200 or retracted from the pin hole 200, thus realizing the installation and removal of the fastener 2.

[0095] In one embodiment, such as Figure 5 As shown, the fastener 2 is provided with a metal fixing shell 20, and the aforementioned snap-fit ​​hole 21 and pin hole 200 are formed on the metal fixing shell 20, thereby preventing the fastener 2 from directly contacting the rotating body 3 and causing wear during long-term installation and removal. In this way, when performing subsequent maintenance on the fastener 2, the metal fixing shell 20 can be directly replaced.

[0096] In one embodiment, the first mating surface 441 and the second mating surface 442 are arranged adjacent to each other, and the second mating surface 442 is set as an inclined surface, so that the end of the spindle 4 away from the equipment body 1 has a trapezoidal profile; the first mating surface, the second mating surface 442 are arranged in correspondence with the third mating surface 443 and the fourth mating surface 444.

[0097] Here, the end of the main shaft 4 has a trapezoidal profile, and the fixing pin 31 is also set to correspond to the trapezoidal profile. The trapezoidal profiles of the two provide a certain displacement space for the extension and retraction of the fixing pin 31. When the user rotates the main body 3, the mating surface moves from the inclined surface to the straight surface or from the straight surface to the inclined surface. When the straight surface and the straight surface are in contact, the fixing pin 31 extends out and when the inclined surface and the inclined surface are in contact, the fixing pin 31 retracts.

[0098] The straight surfaces (vertical surfaces) in the trapezoidal profile are the first mating surface 441 and the third mating surface 443 mentioned above, and the inclined surfaces are the second mating surface 442 and the fourth mating surface 444 mentioned above.

[0099] When two straight surfaces come into contact, the fixing pin 31 is actually pushed outward by the end of the spindle 4 a certain distance. This distance is the length of the projection of the inclined surface onto its displacement direction F1. Through this process, the end of the fixing pin 31 is exposed through the through hole 32. When two inclined surfaces come into contact, the fixing pin 31 retracts inward under the action of the elastic member 310. Similarly, the distance that the fixing pin 31 retracts inward is the length of the projection of the inclined surface onto its displacement direction F1.

[0100] Of course, the above design also needs to take into account the length of parts such as the fixing pin 31, the rotating body 3, and the through hole 32, to prevent the fixing pin 31 from extending or retracting at an inappropriate length, so as to avoid affecting the installation and disassembly effect of the fastener 2; in addition, the inclined surface can also play a guiding role, making the extension and retraction of the fixing pin 31 more stable.

[0101] In another embodiment, the number of fixing pins 31 is at least two.

[0102] Furthermore, the second mating surface 442 rotates in the axial direction to form a conical surface, so that when the rotating body 3 rotates relative to the main shaft 4 to the second preset position, each fourth mating surface 444 can be mated with the conical surface.

[0103] Understandably, the conical surface formed by the second mating surface 442 on the main shaft 4 enables the main shaft 4 to achieve circumferential mating, providing a basis for adding fixing pins 31. Operators or technicians can adjust the number of fixing pins 31 or the shape of the rotating body 3 according to specific needs, so that the quick-release mechanism 13 has stronger fixing ability and adapts to the diverse needs of different equipment and fasteners 2 during loading and unloading.

[0104] In one embodiment, the end of the spindle 4 with a trapezoidal profile is configured as a dial 42.

[0105] A partition ring 43 is also provided on the outer periphery of the main shaft 4. The inclined surface faces closer to the partition ring 43, and there is a gap between the partition ring 43 and the dial head 42. When the rotating body 3 rotates relative to the main shaft 4 to the second preset position, part of the fixing pin 31 is limited between the partition ring 43 and the dial head 42.

[0106] It should be noted that in actual production, due to the relatively complex structure of the spindle 4, it is usually first processed into two or more parts before being assembled.

[0107] like Figure 7 As shown, the main shaft 4 is formed by threaded connection of lever 41 and main dial 42. The main dial 42 includes the aforementioned dial 42 and a spacer ring 43, which facilitates subsequent assembly and forming. Of course, in other embodiments, lever 41 and main dial 42 can be integrally formed.

[0108] In addition, the partition ring 43 in this embodiment provides a certain space for the fixing pin 31. When the fixing pin 31 is retracted inward, it can be locked between the partition ring 43 and the dial 42, making the fixing pin 31 less prone to shaking and avoiding mutual collision of the internal structure of the quick-release component.

[0109] In one embodiment, see Appendix Figure 1 and Figure 6 The outer periphery of the main shaft 4 is also provided with a protrusion 400. The rotating body 3 extends along the axial direction of the main shaft 4 to form a hollow sleeve 30. The hollow sleeve 30 is connected to the accommodating cavity 33, and the inner periphery of the hollow sleeve 30 is provided with a track 301 that is connected to the protrusion 400.

[0110] The aforementioned track 301 has a closed loop structure with its ends connected, and there is a height difference between the highest point S1 and the lowest point S2 of the track 301. This causes the track 301 to slide relative to the protrusion 400 when the rotating body 3 rotates relative to the main shaft 4, thereby causing the main shaft 4 to reciprocate axially relative to the rotating body 3 to adjust the relative position between the dial head 42 and the fixing pin 31.

[0111] It should be noted that, through the setting of the protrusion 400 and the track 301, the main shaft 4 can synchronously reciprocate in the axial direction during the rotation of the rotating body 3 relative to the main shaft 4, so the fixing pin 31 can extend and retract during its translation. Moreover, since the track 301 forms a closed loop, the fixing pin 31 can freely extend or retract regardless of the direction in which the body 3 is rotated, so as to achieve stepless adjustment and improve the user experience.

[0112] Specifically, as can be understood from the attached drawings, the protrusion 400 abuts against the track 301. Thus, when the rotating body 3 rotates, the relative position of the protrusion 400 on the track 301 will also change. Since the circumferential rotation of the main shaft 4 has been restricted by the aforementioned limiting structure, the main shaft 4 will only translate relative to the rotating body 3, that is, move up and down from the perspective of the attached drawings. During its up and down movement, the dial 42 abuts against the fixing pins 31 on both sides, and the extension and retraction of the fixing pins 31 is achieved through the previously described change relationship between the inclined surface and the straight surface.

[0113] In addition, we can understand that the first preset position is the position of the rotating body 3 when the protrusion 400 is at the highest point S1 of the track 301, and the second preset position is the position of the rotating body 3 when the protrusion 400 is at the lowest point S2 of the track 301.

[0114] Based on the above embodiment, grooves 6 that cooperate with protrusions 400 are respectively provided at the highest point S1 and the lowest point S2 of the track 301. When the rotating body 3 rotates relative to the main shaft 4 to the first preset position or the second preset position, at least part of the protrusions 400 are embedded in the corresponding grooves 6 to prevent the protrusions 400 from slipping.

[0115] For reference, see the appendix. Figure 6The lowest point S2 and the highest point S1 of the track 301 are both designed with grooves 6. When the fixing pin 31 is retracted or extended, the protrusion 400 can be inserted into the groove 6, thereby ensuring the relative fixation between the protrusion 400 and the track 301, further improving the reliability of the component, and preventing slight slippage between the protrusion 400 and the track 301 in case of accidents, which would cause the extension and retraction of the fixing pin 31 to fail to achieve the expected results.

[0116] When the rotating body 3 rotates relative to the main shaft 4 to the first preset position, that is, the protrusion 400 is located at the highest point S1 of the track; when the rotating body 3 rotates relative to the main shaft 4 to the second preset position, that is, the protrusion 400 is located at the lowest point S2 of the track 301.

[0117] Furthermore, the groove 6 includes two guide surfaces 61 and a limiting surface 62 connected to the two guide surfaces 61. The guide surfaces 61 are inclined from the opening of the groove 6 toward the limiting surface 62, so that the opening width of the groove 6 gradually increases.

[0118] It is understandable that, since the protrusion 400 is embedded in the groove 6, when the protrusion 400 is about to enter the track 301, the two guide surfaces 61 of the groove 6 can guide the protrusion 400 to slide out of the groove 6 and into the track 301. That is to say, a transition part can also be provided between the groove 6 and the two side tracks 301, so that the movement of the protrusion 400 is smoother and it is easier to assemble and disassemble the main body 1 and the fixing part 2, thereby improving the user's experience.

[0119] Furthermore, such as Figure 1 As shown, a spring 5 is fixed between the track 301 and the partition ring 43, and the spring 5 is sleeved on the outer periphery of the main shaft 4.

[0120] When the rotating body 3 rotates relative to the main shaft 4 to the first preset position, the protrusion 400 connects with the highest point S1 of the track 301. At this time, the distance between the partition ring 43 and the bottom of the track 301 is the smallest. The spring 5 is compressed and generates a rebound force, and the protrusion 400 and the corresponding groove 6 press against each other.

[0121] In other embodiments, when the rotating body 3 rotates relative to the main shaft 4 to the second preset position, the protrusion 400 connects with the lowest point S2 of the track 301. At this time, the distance between the partition ring 43 and the bottom of the track 301 is the largest, causing the spring 5 to be pulled and generate a rebound force. The inclined surfaces on the dial 42 and the fixing pin 31 also abut against each other, thereby pressing the dial 42 and the fixing pin 31 together through the rebound force of the spring 5.

[0122] It is understandable that a spring 5 is installed between the track 301 and the spacer ring 43. The spring 5 is sleeved on the outer circumference of the main shaft 4. When the rotating body 3 rotates relative to the main shaft 4 to the first preset position, the spring 5 is compressed to generate a rebound force, so that the protrusion presses against the corresponding groove 6, thereby enhancing the connection strength between the equipment body 1 and the fixing member 2. Furthermore, when the rotating body 3 rotates relative to the main shaft 4 to the second preset position, the spring 5 is stretched to generate a rebound force, so that the main shaft is subjected to a rebound force after the second preset position, that is, the rotating body 3 can rotate back to the first preset position relative to the main shaft 4, thereby ensuring the fixed connection between the equipment body 1 and the fixing member 2.

[0123] In one embodiment, the end of the fixing pin 31 away from the main shaft 4 is provided with a limiting protrusion (not shown). The limiting protrusion is configured to abut against the inner wall surface of the rotating body 3 when the fixing pin 31 extends away from the main shaft 4 through the through hole 32, so as to limit the extension distance of the fixing pin 31.

[0124] It is understandable that by setting the limiting protrusion, the extension length of the fixing pin 31 relative to the rotating body 3 can be limited, so that when disassembled, the fixing pin 31 will not be extended without restriction by the action of the springs 5 ​​on both sides, which would make it difficult to insert into the pin hole 200 during assembly.

[0125] In one embodiment, refer to the appendix to the specification. Figure 2 According to another aspect of the present invention, the present invention further provides a wearable device 11, which includes a wearable body and a wearing component, the wearable body and the wearing component being detachably connected, and the wearable device 11 also includes the aforementioned quick-release component.

[0126] The wearable body serves as the main body of the device 1, the wearing part serves as the fixing part 2, and the quick-release mechanism 13 is set on the wearable body, thereby realizing the quick assembly and disassembly between the wearable body and the wearing part.

[0127] The wearable device 11 in this application embodiment may include, but is not limited to, smartwatches, smart bracelets, smart armbands, smart glasses, and smart legbands, etc., and this application embodiment does not limit it. For example, when the wearable device 11 is a smartwatch, the wearing component may be the smartwatch strap; when the wearable device 11 is a smart armband, the wearing component may be the armband of the smart armband.

[0128] In one embodiment, when the quick-release mechanism 13 is provided on the wearable body, the wearable part is provided with the aforementioned snap-fit ​​hole 21 (e.g. Figure 2 As shown), the snap-fit ​​hole 21 is used to snap with the rotating body 3. The snap-fit ​​hole 21 is provided with a pin hole 200, which is configured to allow the fixing pin 31 to be inserted to fix the wearer to the wearer body.

[0129] It is understandable that the wearing piece is connected to the rotating body 3 through the snap-fit ​​hole 21 provided on it, and the outline of the pin hole 200 also matches the end of the fixing pin 31. When the user uses it, he puts the wearing piece on the rotating body 3, and the wearing piece will drive the rotating body 3 to rotate, so as to simultaneously achieve the extension and retraction of the fixing pin 31, thereby allowing the fixing pin to be inserted into the pin hole 200 or retracted from the pin hole 200, thus realizing the installation and removal of the wearing piece.

[0130] In one embodiment, the wearable device is provided with a metal retaining shell 20, which is configured to form a snap-fit ​​hole 21 and a pin hole 200. It is understood that the metal retaining shell 20 can prevent the wearable device from directly contacting the rotating body 3 and causing wear during long-term installation and removal. Thus, when performing subsequent maintenance on the wearable device, the metal retaining shell 20 can be directly replaced, thereby improving the service life of the wearable device 11 and facilitating replacement and maintenance.

[0131] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
