Description

TECHNICAL FIELD

[0001] The present application relates to the field of watch accessories, in particular to a watchband quick-release mechanism. BACKGROUND

[0002] It is known that the watchband is the part that effectively fixes the watch on the wearer's wrist, and the watchband is generally connected with the watch dial through a lug mechanism for the replacement of the watchband. The two sections of the watchband are generally connected through a butterfly buckle, a needle buckle, a folding buckle, etc. to facilitate the fixation of the watch on the wrist.

[0003] When the watch is worn on the wrist, the length of the watchband needs to fit the thickness of the wearer's wrist to ensure comfort. Usually, the length of the watchband is adjusted to control the length, such as a watchband length adjustment device disclosed in the publication No. 106617527B and published on January 25, 2019. The device includes a press, a large inner container, and an adjustment link. The large inner container and the adjustment link are hingedly connected and respectively include a structure that is buckled with the press. By buckling the large inner container or the adjustment link with the press, the length of the watchband is adjusted. In the specific embodiment, a watchband length adjustment device, a watchband, and a watch are provided. The watchband length adjustment device includes a press, a large inner container, and an adjustment link. The press can be buckled with the large inner container and the adjustment link according to the length of the watchband. When the press is buckled with different structures, different lengths are presented to facilitate the adjustment of the length of the watchband.

[0004] For some leather or rubber watchbands, the length of the watchband can be adjusted by punching holes on the watchband and using a needle buckle, or directly cutting to achieve the length adjustment. However, in the prior art, most of the leather or rubber watchbands are only suitable for low-end watches, and high-end watches still basically use metal watchbands. For the length adjustment of some metal watchbands, special tools are needed to disassemble the sections to achieve the length adjustment of the watchband, which is undoubtedly not very convenient for the wearer to adjust it by himself according to his own needs. SUMMARY

[0005] The purpose of the present application is to provide a watchband quick-release mechanism to solve the technical problems in the related art.

[0006] In order to achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0009] The movable block has a tendency to always approach the support under the elastic force of the first elastic member.

[0010] A limiting groove is formed in the circumferential outer wall of the second segment, a quick-release groove is formed in the axial outer wall of the second segment, one end of the quick-release groove is connected with the limiting groove, and a limiting pin is arranged on the inner wall of the circular hole; when the position of the limiting pin in the limiting groove is staggered with the quick-release groove, the movable block cannot be separated from the second rod body.

[0011] The movable block has a tendency to always move away from the support under the elastic force of the first elastic member.

[0012] The quick-release groove includes a straight segment parallel to the axial direction of the second segment and a spiral segment, the movable block gradually separates from the second rod body in the moving stroke of the limiting pin along the straight segment towards the spiral segment, and the movable block is deflected away from the second rod body with the second segment as the axis in the moving stroke of the limiting pin away from the straight segment along the spiral segment.

[0013] A limiting plate is slidably arranged on the support, a second elastic member is connected between the limiting plate and the support in the sliding direction, the limiting pin is connected to the limiting plate, and an unlimiting groove is formed in the support of the latter segment; the radial depth of the limiting groove on the second segment is greater than the radial depth of the quick-release groove, the limiting pin on one segment reaches a position where the circumferential surface of the deepest part of the quick-release groove is flush when the limiting plate on one segment is inserted with the unlimiting groove on the latter segment; and the limiting pin on one segment enters the limiting groove below the flush position of the deepest part of the quick-release groove when the limiting plate on one segment is separated from the unlimiting groove on the latter segment.

[0015] The length of the unlimiting groove is equal to the width of the support in the axial direction of the second rod body.

[0016] The limiting pin is still in the quick release slot when the second elastic member does not generate elastic force on the limiting plate.

[0017] The application has the beneficial effect that by simultaneously disconnecting the movable block on one section from the first rod body and the second rod body, the support on the next section can be disconnected and inserted with the second rod body on the one section, so that the metal watchband can be quickly released to adjust the length of the watchband, which is simple and convenient for the wearer to operate and quickly adjust the wearing length of the watchband according to the needs.

DETAILED DESCRIPTION

[0026] In order to make those skilled in the art better understand the technical solutions of the present application, the following will combine the drawings needed in the embodiments with the Figure 1 to the drawingsFigure 5 The application will be further described.

[0027] In the description of the application, it should be understood that the terms "length", "width", "degree", "axial direction", "radial direction", "circumferential direction" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0028] The first embodiment of the application provides a watchband quick release mechanism, which comprises a body of a watchband, the body is composed of a plurality of segments 1 connected in sequence, the segment 1 comprises a fixed block 2, a support 3 and a movable block 4; the support 3 is rotatably provided with a first rod body 5, the fixed block 2 is fixedly connected with one end of the first rod body 5, and the movable block 4 is inserted with the other end of the first rod body 5; the fixed block 2 is rotatably provided with a second rod body 6, and the movable block 4 is inserted with the second rod body 6; the second rod body 6 on one segment 1 is inserted with the support 3 on the next segment 1.

[0029] Specifically, the watchband in the embodiment is a metal watchband, which is connected by a plurality of segments 1 in sequence, wherein the watchband is connected with the watch dial through a lug mechanism at one end, and two segments of the watchband are connected through a butterfly buckle. Each segment 1 is arranged along the width direction of the watchband in sequence by a fixed block 2, a support 3 and a movable block 4. The first rod body 5 and the second rod body 6 are both cylindrical. When the fixed block 2, the support 3 and the movable block 4 of each segment 1 are connected through the first rod body 5, the three can rotate around the first rod body 5 as the axis. The second rod body 6 is further connected between the fixed block 2 and the movable block 4. The positional relationship between the first rod body 5 and the second rod body 6 is preferably symmetrical arrangement with the center line of the fixed block 2 along the length direction of the watchband as the axis of symmetry. The position of the second rod body 6 does not affect the rotation of the support 3 on the first rod body 5. The second rod body 6 on one segment 1 is inserted with the support 3 on the next segment 1, and the support 3 on the next segment 1 can also rotate on the second rod body 6 on one segment 1 along the axis of the second rod body 6. That is, the segment 1 connected with the watch dial is the first segment, and then the second segment, the third segment, the fourth segment and so on in sequence along the length direction of the watchband. The second rod body 6 on the first segment 1 and the support 3 on the second segment 1 can slide axially or rotate circumferentially. The second rod body 6 on the second segment 1 and the support 3 on the third segment 1 can also slide axially or rotate circumferentially. Similarly, the adjacent two segments 1 are connected in this way. The movable block 4 on each segment 1 is connected with the first rod body 5 and the second rod body 6 in the form of insertion, that is, it can be disassembled. When the movable block 4 is inserted with the first rod body 5 and the second rod body 6, it is limited by friction to prevent the movable block 4 from easily separating from the first rod body 5 and the second rod body 6.

[0030] When the wearer needs to adjust the length of the watchband, one or more segments 1 can be removed manually. The position where the segment 1 is removed can be close to the lug mechanism or close to the butterfly buckle. The removal method is to first disconnect the connection between the watchband and the lug mechanism or the butterfly buckle, which is a prior art and will not be described in detail. Then, according to the need to remove several segments 1, the insertion of the movable block 4, the first rod body 5 and the second rod body 6 of the segment 1 is manually disengaged from the first segment 1. In this way, the support 3 connected to the second rod body 6 is no longer limited by the movable block 4. Then, the support 3 and the first rod body 5 and the second rod body 6 are removed. In this way, the end of the remaining part of the watchband is the second rod body 6 of a segment. Finally, it can be connected with the lug mechanism or the butterfly buckle to complete the length adjustment of the watchband. In this way, the disassembly of one or more segments can be completed by first removing the movable block 4 and then removing the remaining part.

[0031] The beneficial effect of the embodiment is that by simultaneously disconnecting the movable block 4 on a section 1 from the first rod body 5 and the second rod body 6, the support 3 on the subsequent section 1 can be disconnected and inserted with the second rod body 6 on the section 1, so that the metal watchband can be quickly disassembled to adjust the length of the watchband, which is simple and convenient for the wearer to quickly adjust the wearing length of the watchband according to his own needs.

[0032] Preferably, the first rod body 5 comprises a first section 50 fixedly connected with the fixed block 2 and a second section 51 inserted with the movable block 4, the first section 50 and the second section 51 are in a split structure, their movements do not affect each other, and the first section 50 is rotationally connected with the support 3 and is limited from moving axially away from the support 3 by a limiting structure; a circular hole 52 is formed in the support 3, the second section 51 slides axially in the circular hole 52, and a first elastic member 53 is connected between the second section 51 and the support 3 in the sliding direction of the second section 51; under the elastic force of the first elastic member 53, the movable block 4 has a tendency to always approach the support 3.

[0033] Specifically, as known from the foregoing, the second section 51 can not only slide axially but also rotate circumferentially in the circular hole 52, so as not to affect the mobility between the fixed block 2, the support 3 and the movable block 4, so that the watchband can better fit the wrist when worn. In the foregoing, the movable block 4 and the first rod body 5 and the second rod body 6 are all limited by friction through insertion, so as to prevent the movable block 4 from easily detaching from the first rod body 5 and the second rod body 6. However, during the wearing of the watch, it is inevitable to have accidental contact. In the case of a very small probability, when the movable block 4 happens to be subjected to a force along the axial direction of the second rod body 6, the force makes the movable block 4 have a tendency to detach from the second section 51 and the second rod body 6. When the movable block 4 overcomes the frictional resistance between the movable block 4 and the second section 51 and the second rod body 6 after being subjected to the force, the possibility of the movable block 4 detaching from the second section 51 and the second rod body 6 also increases. Therefore, the movable block 4 has a risk of being accidentally disassembled. When the movable block 4 is accidentally disassembled, the watch has a risk of being lost. Therefore, in the embodiment, the first elastic member 53 is connected between the second section 51 and the support 3. The elastic force provided by the first elastic member 53 makes the movable block 4 have a tendency to always approach the support 3. That is, after the movable block 4 is subjected to the force along the axial direction of the second rod body 6, the elastic force of the first elastic member 53 provides a counterforce to prevent the movable block 4 from detaching from the second rod body 6.

[0034] The limiting structure is used to limit the first section 50 from axially detaching from the support 3. The first section 50 can be provided as two sections with different diameters, the thin section is fixedly connected with the fixed block 2, and the thick section is rotationally connected with the support 3. A limiting ring is fixedly connected with the support 3 at a position corresponding to the junction of the thick section and the thin section, so as to limit the first section 50 from axially detaching from the support 3.

[0035] In the second embodiment of the present application, a ring-shaped limiting groove 54 is formed on the circumferential outer wall of the second section 51, a quick-release groove 55 is formed on the axial outer wall of the second section 51, one end of the quick-release groove 55 is in communication with the limiting groove 54, and a limiting pin 56 is arranged on the inner wall of the round hole 52. Obviously, when the limiting pin 56 is in the position in the limiting groove 54 and is staggered with the quick-release groove 55, the movable block 4 cannot be separated from the second rod body 6.

[0036] Specifically, the limiting groove 54 is in a ring shape, when the limiting pin 56 is inserted into the limiting groove 54, the second section 51 can rotate freely in the circumferential direction without being hindered by the limiting pin 56, when the limiting pin 56 is aligned with the quick-release groove 55, the second section 51 can be pulled out of the round hole 52 in the axial direction without being limited, at this time, the limiting pin 56 will enter the quick-release groove 55, so that the movable block 4 can be separated from the second rod body 6, when the watch band is worn, the entire watch band is wrapped around the wrist, that is, there is a certain angle between the adjacent two sections 1, and there is also an angle between the bracket 3 on one section, the fixed block 2 and the movable block 4 (because the bracket 3 is rotationally connected with the first rod body 5), at this time, the limiting pin 56 is in the limiting groove 54 but is staggered with the quick-release groove 55 in the axial direction with a high probability, so that when the movable block 4 is acted on by an external force, the movable block 4 cannot move along the axial direction of the second rod body 6 to separate from the second rod body 6, and the use of the limiting groove 54 and the limiting pin 56 plays a better role in preventing accidental touch, because in the foregoing embodiment, the first elastic member 53 can only limit the movement of the movable block 4 in a small range, when the movable block 4 is pushed to a position sufficient to separate from the second rod body 6, the watch band still has the risk of being disconnected, resulting in the loss of the watch, and in the present embodiment, during the wearing of the watch, the angle change between the bracket 3 and the fixed block 2 (the angle between the bracket 3 and the fixed block 2 is less than 180 degrees when worn) causes the limiting pin 56 to be staggered with the quick-release groove 55 in the circumferential direction when the limiting pin 56 is in the limiting groove 54, thereby better preventing the movable block 4 from being accidentally separated from the second rod body 6, when the length of the watch band needs to be adjusted, the angle between the bracket 3 and the fixed block 2 in the section 1 to be removed is adjusted to 180 degrees, and the limiting pin 56 is aligned with the quick-release groove 55 in the axial direction.

[0037] Further, under the elastic force of the first elastic member 53, the movable block 4 has a tendency to always move away from the support 3; in particular, because the wristwatch is worn on the wrist and its size cannot be too large, the volume of each movable block 4 is also small, and if the first elastic member 53 has a tendency to always move the movable block 4 close to the support 3 under the elastic force as described in the foregoing embodiment, after the limiting pin 56 is axially aligned with the quick-release slot 55, the movable block 4 still needs to be pinched and pulled to separate it from the second rod body 6, and in this process, the elastic force of the first elastic member 53 is also increasing, so that the small movable block 4 is not convenient to be pinched and moved in the direction resisting the elastic force of the first elastic member 53, and therefore in this embodiment, the elastic force of the first elastic member 53 has a tendency to always move the movable block 4 away from the support 3, so that when the limiting pin 56 is axially aligned with the quick-release slot 55, the movable block 4 can be automatically separated from the second rod body 6 along the axial direction of the second rod body 6 by using the elastic force of the first elastic member 53, thereby achieving the purpose of quick release.

[0038] Further, the quick-release slot 55 includes a straight line segment 550 parallel to the axial direction of the second segment 51 and a spiral segment 551, and in the movement of the limiting pin 56 along the straight line segment 550 towards the spiral segment 551, the movable block 4 is gradually separated from the second rod body 6, and in the movement of the limiting pin 56 along the spiral segment 551 away from the straight line segment 550, the movable block 4 is deflected away from the second rod body 6 with the second segment 51 as the axis.

[0039] Specifically, one end of the straight section 550 is in communication with the limiting groove 54, and the other end is connected with the spiral section 551, the spiral section 551 is opened along the outer wall of the second section 51, when the limiting pin 56 slides in the spiral section 551, it can move along the axial direction of the second section 51 and also can slide along the circumferential direction of the second section 51, that is, when it is needed to remove some segments 1 of the watchband, the included angle between the bracket 3 and the fixed block 2 in the segment 1 to be removed is adjusted to 180 degrees, the limiting pin 56 will be aligned with the quick release slot 55 in the axial direction, that is, the second section 51 drives the movable block 4 to move away from the second rod body 6 along the axial direction under the action of the elastic force of the first elastic member 53, in this process, the limiting pin 56 will slide from the limiting groove 54 into the straight section 550, when the movable block 4 is completely separated from the second rod body 6, the limiting pin 56 is at the junction of the straight section 550 and the spiral section 551, with the continuous action of the elastic force of the first elastic member 53 to drive the movable block 4 to move away from the second rod body 6, then the limiting pin 56 will enter the spiral section 551, and the elastic force of the first elastic member 53 to the second section 51 is along the axial direction, so the side wall of the spiral section 551 will give the limiting pin 56 a pressing force, in turn, the limiting pin 56 gives the spiral section 551 a pressing force, then the second section 51 continues to move and will move along the axial direction while rotating along its own axis, so that the movable block 4 can also be deflected after being separated from the second rod body 6, without manually rotating the movable block 4, it can also make the movable block 4 deviate from the second rod body 6 in the axial direction, and when the bracket 3 on the next segment 1 is pulled out of the second rod body 6 on the segment 1, the movable block 4 does not need to be separated from the second rod body 6 in the axial direction, and the width of the bracket 3 is at least the length of the bracket 3 to make the bracket 3 and the second rod body 6 separate smoothly.

[0040] The fixed block 2 is connected with the bracket 3 through the first section 50, and due to the limitation of the limiting ring, the two will not be separated, the movable block 4 is connected with the bracket 3 through the second section 51, and due to the limitation of the quick release slot 55, the two will not be separated, after adjusting the length of the watchband, the segment 1 is not removed separately, and the parts of each segment 1 are still assembled together, because the size of the parts required by the watchband is very small, such design in the embodiment can avoid the loss of the removed parts.

[0041] The third embodiment of the present application further comprises a limiting plate 30 sliding on the bracket 3, the limiting plate 30 is connected with the bracket 3 by a second elastic member 31 in the sliding direction, the limiting pin 56 is connected to the limiting plate 30, and the bracket 3 on the last segment 1 is provided with a releasing slot 32; the depth of the limiting slot 54 in the radial direction on the second segment 51 is greater than the depth of the quick release slot 55 in the radial direction, when the limiting plate 30 on a segment 1 is inserted into the releasing slot 32 on the last segment 1, the limiting pin 56 on the segment 1 reaches the position where the quick release slot 55 is flush in the circumferential direction; when the limiting plate 30 on a segment 1 is disengaged from the releasing slot 32 on the last segment 1, the limiting pin 56 on the segment 1 enters the limiting slot 54 and is lower than the position where the quick release slot 55 is flush; when the second elastic member 31 does not generate elastic force on the limiting plate 30, the limiting pin 56 is still in the quick release slot 55.

[0042] Specifically, in the foregoing embodiments, when some segments 1 need to be removed, the angle between the bracket 3 and the fixed block 2 in the segment 1 to be removed is adjusted to 180 degrees, and the quick release slot 55 and the limiting pin 56 are aligned, under the elastic force of the first elastic member 53, the second segment 51 can drive the movable block 4 to disengage from the second rod body 6; in this embodiment, when the quick release slot 55 and the limiting pin 56 are not aligned in the axial direction, even if the movable block 4 is accidentally touched, the movable block 4 will not disengage from the second rod body 6, but if the segment 1 to be removed is squeezed between the bracket 3 and the fixed block 2 at the same time when it is accidentally touched, the angle between the bracket 3 and the fixed block 2 will change to 180 degrees, and the quick release slot 55 and the limiting pin 56 will be aligned in the axial direction, so that the segments 1 of the watchband will be disconnected, therefore, in this embodiment, the effect of preventing accidental disassembly is further improved based on the foregoing embodiment.

[0043] The sliding direction of the limiting plate 30 is the length direction of the watchband, and the sliding direction is parallel to the length direction of the support 3 which is slidably connected with the limiting plate 30. A releasing slot 32 is formed on the support 3 of each segment 1. The releasing slot 32 on each support 3 and the position of the limiting plate 30 are located at the two ends of the length direction of the support 3. When the watchband is worn, the distance between the releasing slot 32 and the wrist is greater than the distance between the limiting plate 30 and the wrist. Therefore, when the limiting plate 30 on one segment 1 needs to be inserted into the releasing slot 32 on the next segment 1, the two segments 1 are not in the same straight line in the length direction of the watchband. That is, the included angle between the two adjacent segments 1 is less than 180 degrees when the watchband is worn. When one segment 1 needs to be removed, the included angle between the segment 1 to be removed and the adjacent segment 1 which does not need to be removed should be greater than 180 degrees. The limiting plate 30 on the segment 1 to be removed is aligned and inserted into the releasing slot 32 on the adjacent segment 1 which does not need to be removed. For example, when the included angle between the two segments 1 is 200 degrees, the limiting plate 30 is inserted into the releasing slot 32 under the elastic force of the second elastic member 31. When the limiting plate 30 is not inserted into the corresponding releasing slot 32, the support 3 of the next segment 1 always exerts a pressing force on the limiting plate 30 of the support 3 of one segment 1, so that the limiting plate 30 tends to retract into the support 3. The second elastic member 31 is compressed to generate an elastic force. The limiting pin 56 is inserted into the limiting slot 54 under the driving of the limiting plate 30. At this time, the watchband is worn, and the included angle between the two adjacent segments 1 is less than 180 degrees. Therefore, the limiting pin 56 and the quick release slot 55 are misaligned. During the wearing of the watchband, the segment 1 is pressed by an external force, and the included angle between the two adjacent segments 1 is gradually increased. Therefore, the segment 1 under the external force exerts a pressing force on the wrist. The wrist hinders the segment 1 under the external force. Therefore, the anti-removal effect of the watchband is further improved.

[0044] During the wearing of the watchband, the limiting plate 30 on one segment 1 always interacts with the end of the support 3 of the next segment 1 under the elastic force of the second elastic member 31. When the two adjacent segments 1 do not abut against each other, the second elastic member 31 makes the two adjacent segments 1 have elasticity. The elasticity makes the included angle between the two adjacent segments 1 increase, that is, the watchband has a tendency to straighten from bending. Therefore, the watchband has a tendency to expand outward when the watchband is worn. Therefore, the compression of the watchband on the wrist is reduced.

[0045] Wherein, when one segment 1 is disassembled, the second rod body 6 and the bracket 3 are disconnected, the bracket 3 is not hindered, that is, the disengaging slot 32 and the limiting plate 30 are not interacted, in the embodiment, the length of the disengaging slot 32 is equal to the width of the bracket 3 in the axial direction of the second rod body 6, that is, the limiting plate 30 and the disengaging slot 32 can slide freely in the axial direction of the second rod body 6.

[0046] In the alternative embodiment, further, the bracket 3 is provided with a limiting channel 33, when the limiting plate 30 on one segment 1 is disconnected from the disengaging slot 32 on the next segment 1, the limiting plate 30 on one segment 1 enters the limiting channel 33 on the next segment 1, and the bracket 3 on the next segment 1 cannot slide axially on the second rod body 6 on one segment 1.

[0047] Specifically, the watchband is designed to adapt to the shape of the wrist, and the two adjacent segments 1 can rotate relative to each other to wrap the wrist, in order to avoid friction and limit, there is a gap between the fixed block 2, the movable block 4 on one segment 1 and the bracket 3 on the next segment 1 during installation, that is, after the bracket 3 on the next segment 1 is inserted into the second rod body 6 on one segment 1, the bracket 3 can slide axially on the second rod body 6, then during wearing, the gap between the fixed block 2 or the movable block 4 on one segment 1 and the bracket 3 on the next segment 1 will be reduced, so that the wrist skin is clamped, in the embodiment, the limiting channel 33 is provided, the length of the limiting channel 33 in the width direction of the bracket 3 is basically equal to the length of the limiting plate 30 in the width direction of the bracket 3, so that the relative sliding of the limiting channel 33 and the limiting plate 30 in the axial direction is limited, and the limiting plate 30 and the limiting channel 33 are located between the adjacent segments 1, during wearing of the watchband, the wrist skin cannot contact the limiting plate 30 and the limiting channel 33, so that the wrist skin is not clamped.

[0048] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application.
