The watch clasp in this embodiment includes a clasp frame 1, a first clasp tongue assembly 2, and a safety clasp 4 for securing a watch band, wherein: the first end of the first buckle tongue component 2 is hinged and fixed with the buckle making frame 1 through a first pin shaft 101, the second end of the first buckle tongue component 2 is hinged and fixed with the safety buckle 4 through a second pin shaft, and when the first buckle tongue component 2 is buckled to the buckle making frame 1 around the first pin shaft 101 and the safety buckle 4 is buckled to the first buckle tongue component 2 around the second pin shaft, the buckle making frame 1, the first buckle tongue component 2 and the safety buckle 4 are overlapped in a Z shape.

As shown in fig. 2, the first latch assembly 2 includes an elastic member (specifically, the elastic member may be disposed in the center of the main body of the first latch assembly 2), a fastening portion and a button portion, and the fastening portion and the button portion are disposed at the second end of the first latch assembly 2 respectively. Particularly, the button portion is mainly used for contracting the width of the elastic member when being pressed, and specifically, when the button portion is pressed, the two sides of the first latch assembly 2 in the width direction contract and move towards the middle to squeeze the elastic member, and the elastic member can be elastically deformed under stress. In practical application, for being convenient for button portion when being pressed the width of shrink elasticity component, can effectively promote joint portion and remove and realize the buckle operation, specifically can set up joint portion and button portion with adjacent mode.

Further, the elastic member penetrates through the length direction of the first latch assembly 2, that is, the first latch assembly 2 is divided into three parts, and the elastic member is located in the middle, so that the elastic member can be squeezed when the two sides of the first latch assembly 2 move towards the middle respectively (are pressed), the width of the elastic member is reduced, elastic deformation is generated, and then the two sides of the first latch assembly 2 (when the elastic member is not pressed to move) can restore to the original position under the elastic action of the elastic member, thereby realizing elastic stretching action. In addition, the fastening frame 1 has the fastening structure 11 corresponding to the fastening portion, which is beneficial to the fastening portion of the first fastening tongue component 2 to be fastened with the fastening structure 11, so that the second end of the first fastening tongue component 2 can be fixed, and the first fastening tongue component 2 is completely restrained and fixed on the fastening frame 1.

When the elastic buckle is used, the button part is pressed first, and the button part drives the two sides of the first buckle tongue component 2 in the width direction to move under stress and contract to extrude the elastic component, so that the elastic component generates elastic deformation; meanwhile, the two sides of the first latch assembly 2 in the width direction drive the clamping portion to move in the opposite direction to the clamping direction of the clamping structure 11 (i.e. move in the direction away from the clamping structure 11), so that the clamping portion can be moved to the corresponding clamping position of the clamping structure 11; then the button part is loosened (i.e. the button part is not pressed), at this time, the elastic member (under the effect of elastic deformation) pushes and presses the two sides of the first buckle tongue component 2 in the width direction, so that the two sides of the first buckle tongue component 2 in the width direction move towards the direction far away from the elastic member, and the clamping part is pushed to move towards the clamping direction of the clamping structure 11, so that the clamping part is clamped and matched with the clamping structure 11 for fixing, and further the second end of the first buckle tongue component 2 is fixed on the clamping frame 1.

In the watch buckle, the elastic member 21 is arranged in the center of the main body part of the first buckle tongue component 2, and the elastic member 21 realizes the telescopic action of the buckle, so that the clamping part of the first buckle tongue component 2 can be stably and efficiently clamped or separated with the buckle structure 11 of the buckle manufacturing frame 1. Different from the current watch buckle which realizes the telescopic action by adopting a spring structure, the watch buckle of the embodiment can realize the switch function without arranging the spring structure, and the shock resistance of the elastic component 21 is strong, so that the overall structural strength of the first buckle tongue component 2 can be greatly increased, the watch buckle is not easy to be damaged by impact, and the service life is prolonged.

In addition, the structure of the watch buckle with the telescopic function realized by the elastic member 21 is relatively simplified, and more structures or parts for matching and positioning are not needed, so that the manufacturing cost and the assembly difficulty can be effectively reduced, the assembly and the maintenance operation are convenient, and the working efficiency is greatly improved.

Specifically, the first buckle tongue assembly 2 described above includes a left core 23 and a right core 24, wherein: the left core-making 23 and the right core-making 24 are symmetrically arranged, the elastic member 21 is in a strip shape with the same length as the left core-making 23 and the right core-making 24, and the elastic member 21 is positioned between the left core-making 23 and the right core-making 24 (the elastic member 21, the left core-making 23 and the right core-making 24 are positioned in the same plane). The elastic member 21 is designed into a strip shape, so that the elastic member 21 is attached and connected with the left core making 23 and the right core making 24, the left core making 23 and the right core making 24 can extrude the elastic member 21 along the width direction, the structural design rationality can be effectively improved, and the processing and the assembly are convenient.

Specifically, in the first tongue assembly 2 described above, the elastic member 21 separates the left core 23 and the right core 24 so that the left core 23 and the right core 24 form portions on both sides in the width direction of the first tongue assembly 2, respectively; when the button portion is pressed, the elastic member 21 positioned in the middle is pressed in the width direction by the left core 23 and the right core 24, and the elastic member 21 is elastically deformed to contract the width.

In practical application, the two side edges of the elastic member 21 in the width direction are arranged in parallel, so that when the left core 23 and the right core 24 extrude the elastic member 21, the elastic member 21 can be stressed uniformly, the pressing operation is facilitated, and of course, the shape design of the elastic member 21 is adjusted according to actual design requirements.

In addition, the above-mentioned buckle making frame 1 includes the first mounting groove 12, and the tail ends of the left making core 23, the elastic member 21 and the right making core 24 are mounted and fixed into the first mounting groove 12 by the first pin 101. Moreover, the distance from the outer side surface of the left core 23 to the outer side surface of the right core 24 corresponds to (is less than or equal to) the width of the first mounting groove 12, so that the left core 23, the elastic member 21 and the right core 24 can be tightly attached to each other, the positions of the left core 23, the elastic member 21 and the right core 24 in the width direction of the first tongue-and-groove assembly 2 are restrained, the occurrence of large-amplitude play is avoided, and the installation can be more stable and reasonable.

Preferably, the elastic member 21 is made of an elastic material (e.g., rubber), and the outer periphery of the elastic member 21 has an annular elastic groove perpendicular to the width direction of the elastic member 21, which is beneficial to improve the elasticity of the elastic member 21 while ensuring the structural strength of the elastic member 21, so that the operability is stronger, and the need of pressing with a large force to contract the width of the elastic member 21 is avoided.

In order to ensure that the button part can effectively move the two sides of the first latch assembly 2 in the width direction to squeeze the elastic member 21 when being pressed, the button part is provided with a left pressing arm 231 positioned on one side of the left core 23 facing away from the right core 24 and a right pressing arm 241 positioned on one side of the right core 24 facing away from the left core 23, and the left pressing arm 231 and the right pressing arm 241 are coaxial, so that the left pressing arm 231 and the right pressing arm 241 can be better stressed when being pressed simultaneously, the stress is more balanced, and the operability is improved. In practical application, the axial directions of the left pressing arm 231 and the right pressing arm 241 are the same as the width direction of the elastic member 21, and at least a part of the elastic member 21 is located on the axial connecting line of the left pressing arm 231 and the right pressing arm 241, so that when the left pressing arm 231 and the right pressing arm 241 are pressed simultaneously, the left core 23 and the right core 24 can efficiently move to press the elastic member 21, the pressing operation is facilitated, the operation sensitivity is improved, and the operation strength during pressing is effectively reduced.

In order to improve the stability of the first tongue assembly 2 when it is fixed to the fastening frame 1, the upper surface of the fastening frame 1 is provided with a button groove 13, that is, when the first tongue assembly 2 is fixed to the fastening frame 1, the left pressing arm 231 and the right pressing arm 241 may respectively have at least a portion embedded and attached to the inner wall of the button groove 13, so that one side of the left pressing arm 231 and the right pressing arm 241 may be attached to the fastening frame 1, and the portion embedded and attached may be hidden in the button groove 13, thereby improving the stability and reliability of the left pressing arm 231 and the right pressing arm 241, and avoiding the exposed outside from being moved by an external impact or causing an erroneous operation to press the fastening portion to be separated from the fastening structure 11.

As shown in fig. 3, the head end of the left core 23 has a first through hole 233 passing through the width direction thereof and the axial direction of the left pressing arm 231, the head end of the elastic member 21 has a second through hole 211 passing through the width direction thereof, and the head end of the right core 24 has a third through hole 242 passing through the width direction thereof and the axial direction of the right pressing arm 241, and at this time, the synchronous connection of the left core 23, the elastic member 21, and the right core 24 can be realized only by coaxially fixing the first through hole 233, the second through hole 211, and the third through hole 242.

Further, the button portion further includes a first rod-shaped key 221 inserted and fixed in the first through hole 233 of the left pressing arm 231 and a second rod-shaped key 222 inserted and fixed in the third through hole 242 of the left pressing arm 231, the length of the second rod-shaped key 222 is smaller than that of the third through hole 242, and the length of the insertion rod of the first rod-shaped key 221 is larger than the sum of the lengths of the first through hole 233 and the second through hole 211; the insertion rod of the first rod-shaped key 211 is sequentially inserted into the first through hole 233, the second through hole 211 and the third through hole 242, and the left core 23, the elastic member 21 and the right core are synchronously connected together; the structure has reasonable and practical design and convenient assembly, can simplify the structure, effectively reduces the number of parts to be assembled, and improves the working efficiency of manufacturing.

Of course, in practical applications, the left core 23, the elastic member 21 and the right core 24 may be directly and synchronously connected by other fixing means, but this will greatly increase the complexity of the structure of the first latch assembly 2.

Particularly, the second pin shaft for the hinged fixation of the safety catch 4 and the first latch assembly 2 is composed of the first rod-shaped key 221 and the second rod-shaped key 222, that is, the first rod-shaped key 221 and the second rod-shaped key 222 can simultaneously connect the left core 23, the elastic member 21 and the right core 24 and simultaneously hinge the safety catch 4 and fix the safety catch 4 at the second end of the first latch assembly 2, thereby improving the practicability of the structural design of the first rod-shaped key 221 and the second rod-shaped key 222 and enabling the structure to be more compact and reasonable.

In order to ensure that the insertion rod of the first rod body key 221 can sequentially pass through the first through hole 233, the second through hole 211 and the third through hole 242, the diameter of the first through hole 233 is larger than or equal to that of the second through hole 211, and the diameter of the second through hole 211 is larger than or equal to that of the third through hole 242; the insertion rod of the first rod key 221 has a first rod corresponding to the first through hole 233, a second rod corresponding to the second through hole 211, and a third rod corresponding to the third through hole 242.

Specifically, the first rod is provided with a positioning threaded hole perpendicular to the axial direction of the insertion rod of the first rod key 221, the side wall of the left pressing arm 231 is provided with a mounting hole corresponding to the positioning threaded hole, and at this time, the insertion rod of the first rod key 221 can be fixedly connected with the left pressing arm 231 through a screw 223 which penetrates through the mounting hole and is in threaded connection with the positioning threaded hole.

In addition, when the diameters of the first through hole 233, the second through hole 211 and the third through hole 242 are the same, the diameters of the first rod body, the second rod body and the third rod body are the same, and because the first rod body is fixedly connected with the left pressing arm 231, at this time, at least one portion of the second rod body penetrates through the second through hole 211, and the other portion penetrates through the first through hole 233, and at least one portion of the third rod body penetrates through the third through hole 242, and the other portion penetrates through the second through hole 211, so that when the left core 23 and the right core 24 extrude the contracting elastic member 21, the other portion of the second rod body moves into the second through hole 211, and the other portion of the third rod body moves into the third through hole 242.

The clamping portion comprises a first protruding block 232 positioned on one side of the left core making 23 opposite to the right core making 24 and a second protruding block positioned on one side of the right core making 24 opposite to the left core making 23, the first protruding block 232 and the second protruding block are coaxial, the first protruding block 232 is adjacent to the left pressing arm 231, and the second protruding block is adjacent to the right pressing arm 241, so that when the left pressing arm 231 and the right pressing arm 241 are pressed, the left core making 23 and the right core making 24 can effectively drive the first protruding block 232 and the second protruding block to move towards the opposite direction of the corresponding clamping direction of the clamping structure 11; or when the left pressing arm 231 and the right pressing arm 241 are not pressed (released), the left core 23 and the right core 24 can effectively drive the first protrusion 232 and the second protrusion to move towards the corresponding buckling direction of the buckling structure 11.

Correspondingly, the fastening structure 11 includes a first fastening groove and a second fastening groove 111 located on a set of opposite side walls in the first mounting groove 12, the first fastening groove corresponds to the first protrusion 232, and the second fastening groove 111 corresponds to the second protrusion. Specifically, when the button portion is pressed, a distance from a free end of the first protrusion 232 to a free end of the second protrusion 232 is smaller than or equal to a distance from an opening plane of the first card slot to an opening plane of the second card slot 111, that is, the first protrusion 232 and the second protrusion can freely (without hindrance) move to the outside of the first mounting groove 12 or move to the outside of the corresponding opening positions of the first card slot and the second card slot 111 in the first mounting groove 12.

In addition, when the button portion is not pressed, the distance from the free end of the first projection 232 to the free end of the second projection is greater than the distance from the opening plane of the first card slot to the opening plane of the second card slot 111, that is, when the first projection 232 and the second projection move to the outer side of the first mounting groove 12, the first projection 232 and the second projection cannot be clamped into the corresponding first card slot and the second card slot 111; and when the first lug 232 and the second lug move to the outer sides of the corresponding opening positions of the first clamping groove and the second clamping groove 111 in the first mounting groove 12, the first lug 232 is clamped and limited in the first clamping groove, and the second lug is clamped and limited in the second clamping groove 111, so that the first buckle tongue component 2 is completely restrained and fixed on the buckle frame 1.

Certainly, in practical application, the first fastening tongue component 2 may be completely restrained and fixed on the fastening frame 1 by other fastening structure modes, and specifically may be adjusted according to actual design requirements.

Particularly, the shape and size of the first mounting groove 12 are matched with those of the main body of the first latch assembly 2, so that the main body of the first latch assembly 2 can be smoothly and rotatably embedded in the first mounting groove 12 around the first pin 101. Further, when the first latch assembly 2 is fixed to the buckle frame 1, the lower surface of the main body of the first latch assembly 2 is flush with or lower than the upper surface of the buckle frame 1; that is, when the first latch assembly 2 is fixed to the buckle system frame 1, the body of the first latch assembly 2 is hidden in the first mounting groove 12 and does not protrude through the upper surface of the buckle system frame 1, so that the appearance can be improved while the mounting stability of the first latch assembly 2 is ensured, and the structure is rationalized.
