Description

Technical Field

[0001] The utility model relates to the field of watches, and more specifically, to a single-press pin fast-release watchband and a watch. Background Art

[0002] A watch, also known as a wristwatch, is an instrument worn on the wrist for timing and displaying time. A watch generally includes a watch head (i.e., for displaying time) and a watchband. The watchband is usually made of materials such as leather, rubber, nylon cloth, and metal (such as stainless steel), etc., and is used to fasten the watch head on the wrist.

[0003] Currently, for the convenience of adjusting the length of the watchband, most metal watchbands on the market adopt a fast-release method, that is, the beads of the watchband can be disassembled without the aid of tools, and the number of beads is increased or decreased to adjust the wearing length of the watchband. However, the structure of the existing fast-release watchband is relatively complex, or there is a large gap between the side beads and the middle beads of the watchband. Summary of the Utility Model

[0004] An embodiment of the utility model aims at the problems of the complex structure of the existing fast-release watchband and the large gap between the side beads and the middle beads of the watchband, and provides a single-press pin fast-release watchband and a watch.

[0005] The technical solution for the utility model to solve the above technical problems is to provide a single-press pin fast-release watchband, which includes a plurality of bead assemblies sequentially connected along the length direction of the watchband. Each bead assembly includes a first side bead, a second side bead, a middle bead, and a fast-release connection assembly, and the front end of the middle bead is connected between the rear ends of the first side bead and the second side bead;

[0006] The inner surface of the front end of the first side bead has a first ear hole, and the center line of the first ear hole is perpendicular to the inner surface of the first side bead; the inner side of the front end of the second side bead has a second ear hole, and the included angle between the center line of the second ear hole and the inner surface of the second side bead is between 45° and 80°; the rear end of the middle bead has a first through hole and a second through hole, and the first through hole penetrates through both side surfaces of the middle bead along the width direction of the watchband, and the second through hole penetrates from the lower surface of the middle bead to the first through hole;

[0007] The quick-release connection assembly includes a first telescopic pin head, a second telescopic pin head, a sliding locking pin, a through tube and an elastic member. The front end of the first telescopic pin head has a first needle head for inserting into the first ear hole of an adjacent bead assembly, and the front end of the second telescopic pin head has a second needle head for inserting into the second ear hole of an adjacent bead assembly. The first telescopic pin head and the second telescopic pin head are respectively slidably disposed in the through tube, and the elastic member is located between the first telescopic pin head and the second telescopic pin head, and pushes the first telescopic pin head and the second telescopic pin head so that the first needle head and the second needle head respectively protrude from two ends of the through tube.

[0008] The through tube is inserted into the first through hole of the middle bead. The first needle head of the first telescopic pin head and the second needle head of the second telescopic pin head respectively protrude from two side walls of the middle bead under the push of the elastic member. The sliding locking pin passes through the second through hole from the surface of the middle bead and is fixed to the first telescopic pin head, and the free end of the first telescopic pin head is retracted into the side wall of the middle bead by sliding along the width direction of the watch band.

[0009] As a further improvement of the present invention, the length of the through tube is less than or equal to the width of the middle bead. When the elastic member is in a natural state, only the first needle head of the first telescopic pin head protrudes from the end of the through tube, and only the second needle head of the second telescopic pin head protrudes from the end of the through tube. The through tube has a third through hole corresponding to the second through hole, and the sliding locking pin passes through the third through hole and is fixed to the first telescopic pin head.

[0010] As a further improvement of the present invention, the quick-release connection assembly further includes a locking pin. The locking pin is disposed in the through tube and located between the elastic member and the first telescopic pin head, and the front end of the locking pin has an axial fixing rod.

[0011] The sliding locking pin has a circumferentially arranged card slot. The end face of the rear end of the first telescopic pin head has an axial mounting hole corresponding to the fixing rod of the locking pin, and the outer peripheral surface of the first telescopic pin head has a radial mounting hole penetrating to the axial mounting hole. The part of the sliding locking pin where the card slot is located sequentially passes through the second through hole and the third through hole and then is inserted into the radial mounting hole, and is clamped with the fixing rod inserted into the axial mounting hole.

[0012] As a further improvement of the present utility model, the diameter of the orifice at the first end of the through tube is larger than the radial dimension of the main body parts of the first telescopic stud head and the second telescopic stud head. The diameter of the orifice at the second end of the through tube is larger than the radial dimension of the second needle tip and smaller than the radial dimension of the main body part of the second telescopic stud head. The second telescopic stud head, the elastic member, the locking pin and the first telescopic stud head are successively assembled into the through tube from the orifice at the first end of the through tube, and the tail end of the sliding locking pin has a conical guiding surface.

[0013] As a further improvement of the present utility model, the center line of the second ear hole is located in a plane perpendicular to the length direction of the watch band, and the center line of the second ear hole is inclined from the opening towards the upper surface direction of the second side bead.

[0014] As a further improvement of the present utility model, the free ends of the first needle tip and the second needle tip respectively have conical surfaces. Below the first ear hole, there is a first sloping groove connected to the lower surface of the first side bead, and below the second ear hole, there is a second sloping groove connected to the lower surface of the second side bead.

[0015] As a further improvement of the present utility model, the head end of the sliding locking pin has a stud head, and the dimension of the stud head along the length direction of the watch band is larger than the dimension of the second through hole along the length direction of the watch band. The lower surface of the middle bead has a groove, and the second through hole penetrates from the bottom of the groove to the first through hole, and the depth of the groove is greater than or equal to the height of the stud head of the sliding locking pin.

[0016] As a further improvement of the present utility model, the dimension of the opening of the second ear hole is larger than the radial dimension of the root of the second needle tip.

[0017] As a further improvement of the present utility model, the rear end face of the middle bead has an embedding groove arranged along the width direction of the watch band, and the front end face of the middle bead has a protruding strip arranged along the width direction of the watch band. When two bead assemblies are connected, the protruding strip of the rear bead assembly is embedded into the embedding groove of the front bead assembly.

[0018] The present utility model also provides a watch, including a watch dial and the single-press stud quick-release watch band as described above.

[0019] The present utility model has the following beneficial effects: By obliquely arranging the center line of the second ear hole of the second side bead, only by pushing the first telescopic stud head to axially move through the sliding locking pin and applying a vertical thrust to the middle bead, the second needle tip of the second telescopic stud head can be pushed out of the second ear hole, and at the same time, the middle bead is pushed to be separated from the adjacent bead assembly, which greatly facilitates the disassembly of adjacent bead assemblies.

[0026] In order to make the objectives, technical solutions, and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and the claims do not use the difference in names as a way to distinguish components, but use the difference in functions of components as the criterion for distinction. As mentioned throughout the specification and claims, "comprising" is an open - ended term and should be interpreted as "including but not limited to". "Substantially" means within an acceptable error range. Those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0028] In the description of the application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0029] In the description of the present application, unless otherwise clearly defined and limited, the terms "first", "second", "third" are only used for the purpose of description and cannot be understood as indicating or implying relative importance; the term "plurality" means two or more; unless otherwise specified or stated, the terms "connection", "fixation", etc. shall be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; "connection" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0030] The single-press pin fast-release watchband of the present utility model can be applied to metal watchbands (such as stainless steel), which can be fixed to the watch case and realize wearing of the watch. The single-press pin fast-release watchband includes a plurality of bead components, and the plurality of bead components are sequentially connected along the length direction of the watchband. In the above single-press pin fast-release watchband, the disassembly and assembly of the bead components can be realized without the aid of tools, so as to conveniently and simply adjust the length of the watchband.

[0031] As Figures 1 - 3 shown, it is a schematic diagram of a bead component in the single-press pin fast-release watchband provided by an embodiment of the present utility model. The bead component includes a first side bead 10, a second side bead 20, a middle bead 30, and a quick-release connection component 40, and the front end of the middle bead 30 is connected between the rear ends of the first side bead 10 and the second side bead 20 (for example, through two spring bars 50). The above first side bead 10, second side bead 20, and middle bead 30 are all processed from metal materials such as stainless steel, and moreover, the above middle bead 30 can be a single component or assembled from multiple components.

[0032] The inner surface of the front end of the first side bead 10 has a first ear hole 11, and the center line of the first ear hole 11 is perpendicular to the inner surface of the first side bead 10; the inner side of the front end of the second side bead 20 has a second ear hole 21, and the included angle between the center line of the second ear hole 21 and the inner surface of the second side bead 20 is between 45° and 80°. Correspondingly, the rear end of the middle bead 30 has a first through hole 31, and the first through hole 31 penetrates through both side surfaces of the middle bead 30 along the width direction of the watchband. Those skilled in the art can understand that the centers of the openings of the first ear hole 11 and the second ear hole 21 are respectively located on the extension line of the center line of the first through hole 31, and the cross-sections of the first ear hole 11, the second ear hole 21, and the first through hole 31 can be circular or any shape the same as the corresponding structure in the existing watchband, and the depths of the first ear hole 11 and the second ear hole 21 can also be similar to the depths of the corresponding structures in the existing watchband. Of course, in actual applications, the second ear hole 21 can also be such that the wall surface of the upper half is arranged along the length direction of the watchband (that is, perpendicular to the inner surface of the second side bead 20), and the wall surface of the lower half is inclined.

[0033] The above-mentioned middle bead 30 further has a second through hole 32, which penetrates from one surface of the middle bead 30 to the first through hole 31. For example, the second through hole 32 can be arranged along the radial direction of the first through hole 31. And, the dimension of the second through hole 32 in the length direction of the watch band is smaller than its dimension in the width direction of the watch band. For example, the second through hole 32 is a waist-shaped hole.

[0034] The quick-release connection assembly 40 includes a first telescopic pin head 41, a second telescopic pin head 42, a sliding locking pin 43, a through pipe 44 and an elastic member 45. The front end of the first telescopic pin head 41 has a first needle head 411 for inserting into the first ear hole 11 of an adjacent bead assembly (the first needle head 411 is arranged along the axial direction of the first telescopic pin head 41), and the front end of the second telescopic pin head 42 has a second needle head 421 for inserting into the second ear hole 21 of an adjacent bead assembly (the second needle head 421 is arranged along the axial direction of the second telescopic pin head 42). Specifically, the radial dimension of the first needle head 411 is smaller than the radial dimension of the main body part of the first telescopic pin head 41, and the radial dimension of the first needle head 411 is adapted to the radial dimension of the first ear hole 11, and its axial dimension is adapted to the depth of the first ear hole 11, so that the first needle head 411 can be inserted into the first ear hole 11 and there will be no obvious shaking; the radial dimension of the second needle head 421 is smaller than the radial dimension of the main body part of the second telescopic pin head 42, and the radial dimension of the second needle head 421 is smaller than the size of the opening of the second ear hole 21, and its axial dimension is also smaller than the depth of the second ear hole 21, so that the second needle head 421 can be inserted into the second ear hole 21 but cannot be inserted into the bottom of the second ear hole 21.

[0035] The through pipe 44 is a columnar body with a central through hole. The radial dimensions of the main body parts of the first telescopic pin head 41, the second telescopic pin head 42 and the elastic member are adapted to the radial dimension of the central through hole of the through pipe 44. The first telescopic pin head 41 and the second telescopic pin head 42 are respectively slidably arranged in the through pipe 44 (that is, in the central through hole of the through pipe 44), and the elastic member 45 is located between the first telescopic pin head 41 and the second telescopic pin head 42 (that is, the elastic head 45 is also located in the through pipe 44, and it can specifically be a compression spring), and pushes the first telescopic pin head 41 and the second telescopic pin head 42 so that the first needle head 411 and the second needle head 421 respectively protrude from the two ends of the through pipe 44.

[0036] The above-mentioned through pipe 44 is inserted into the first through hole 31 of the middle bead 30. When the first needle head 411 of the first telescopic pin head 41 and the second needle head 421 of the second telescopic pin head 42 are not subjected to external forces, they respectively protrude from the two side walls of the middle bead 30 under the push of the elastic member 45. The sliding locking pin 43 passes through the second through hole 32 from the surface of the middle bead 30 and is fixed to the first telescopic pin head 41, and the free end of the first telescopic pin head 41 is retracted into the side wall of the middle bead 30 by sliding along the width direction of the watch band.

[0037] When two bead assemblies are assembled together, the rear end of the middle bead of the front bead assembly is embedded between the first side bead and the second side bead of the rear bead assembly, and the first needle head of the quick-release connection assembly passing through the tail end of the middle bead is inserted into the first ear hole of the first side bead, and the second needle head is inserted into the second ear hole of the second side bead. When it is necessary to disassemble the two bead assemblies, the sliding locking pin 43 can be pushed to move towards the middle of the middle bead. The sliding locking pin 43 drives the first telescopic pin head 41 to slide in the same direction, so that the first needle head 411 retracts into the middle bead 30. At this time, the middle bead 30 is pushed along the inclination direction of the second ear hole 21, and an axial force is applied to the second telescopic pin head 42 through the side wall of the second ear hole 21, so that the second needle head 421 retracts into the middle bead 30. Then, by continuing to push the middle bead 30, the bead assembly can be removed, realizing the disassembly of adjacent bead assemblies, as Figure 6 shown. In particular, to ensure the insertion depth of the second needle head 421 into the second ear hole 21, the size of the opening of the second ear hole 21 is preferably larger than the radial dimension of the root of the second needle head 421 (i.e., the part connected to the main body of the second telescopic pin head 42).

[0038] For the above single-press bolt quick-release watchband, by obliquely setting the center line of the second ear hole 21 of the second side bead 20, only by pushing the first telescopic pin head 41 to move axially with the sliding locking pin 43 and applying a vertical thrust to the middle bead 30, the second needle head 421 of the second telescopic pin head 42 can be pushed out of the second ear hole 21, and at the same time, the middle bead 30 is pushed to separate from the adjacent bead assembly, which greatly facilitates the disassembly of adjacent bead assemblies.

[0039] In an embodiment of the present invention, the length (i.e., the axial dimension) of the through tube 44 is less than or equal to the width of the middle bead 30, and when the elastic member 45 is in a natural state (i.e., no external force is applied to the first telescopic pin head 41 and the second telescopic pin head 42), only the first needle head 411 of the first telescopic pin head 41 protrudes from the end of the through tube 44, and only the second needle head 421 of the second telescopic pin head 42 protrudes from the end of the through tube 44. The through tube 44 has a third through hole 441 corresponding to the second through hole 32 (for example, the radial shape and size of the third through hole 441 are respectively the same as those of the second through hole 32), and when the through tube 44 is installed in the first through hole 31 of the middle bead 30, the third through hole 441 is opposite to the second through hole 32, and the sliding locking pin 43 passes through the third through hole 441 and is fixed to the first telescopic pin head 41.

[0040] In practical applications, the through tube 44 can also be cancelled, and the first telescopic pin head 41, the second telescopic pin head 42, and the elastic member 45 are directly assembled in the first through hole 31 of the middle bead 30, but this will increase the processing difficulty of the first through hole 31 of the middle bead 30.

[0041] In an embodiment of the present utility model, the sliding locking pin 43 can be assembled with the first telescopic pin head 41 in the following manner: The quick-release connection assembly further includes a locking pin 46. The radial dimension of the main body portion of the locking pin 46 is adapted to the radial dimension of the central through hole of the through pipe 44. The locking pin 46 is installed in the through pipe 44 and is located between the elastic member 45 and the first telescopic pin head 41. The front end of the locking pin 46 has an axial fixing rod 461, and the radial dimension of the fixing rod 461 is smaller than the radial dimension of the main body portion of the locking pin 46. Correspondingly, the sliding locking pin 43 has a circumferentially arranged card slot 431. The end face of the rear end of the first telescopic pin head 41 has an axial mounting hole corresponding to the fixing rod 461 of the locking pin 46 (not shown in the figure, and the dimension of the axial mounting hole is adapted to the dimension of the fixing rod). The outer peripheral surface of the first telescopic pin head 41 has a radial mounting hole 412 penetrating through to the axial mounting hole. The portion of the sliding locking pin 43 where the card slot 431 is located sequentially passes through the second through hole 32 and the third through hole 441 and then is inserted into the radial mounting hole, and is clamped with the fixing rod 461 inserted into the axial mounting hole.

[0042] In practical applications, the sliding locking pin 43 can also be assembled with the first telescopic pin head 41 in other ways. For example, a threaded hole is machined on the first telescopic pin head 41, and an external thread is machined at the tail end of the sliding locking pin 43, and the sliding locking pin 43 is threadedly connected to the first telescopic pin head 41. However, in the process of using the watch band, the sliding locking pin 43 may become loose from the first telescopic pin head 41 due to long-term vibration.

[0043] Specifically, the above-mentioned quick-release connection assembly can be assembled together in the following manner: The pipe orifice at the first end of the through pipe 44 is larger than the radial dimensions of the main body parts of the first telescopic pin head 41 and the second telescopic pin head 42 (for example, the dimension of the pipe orifice is the same as the radial dimension of the central through hole), and the pipe orifice at the second end of the through pipe 44 is larger than the radial dimension of the second needle head 421 and smaller than the radial dimension of the main body part of the first telescopic pin head 41. The second telescopic pin head 42, the elastic member 45, the locking pin 46, and the first telescopic pin head 41 are sequentially assembled into the through pipe 44 from the pipe orifice at the first end of the through pipe 44. And, the tail end of the sliding locking pin 43 has a conical guiding surface. In this way, after the through pipe 44 is assembled into the first through hole 31 of the middle bead 30, the sliding locking pin 43 can be directly inserted into the radial mounting hole 412 through the second through hole 32 and the third through hole 441. The conical guiding surface of the sliding locking pin 43 pushes the fixing rod 461 and the locking pin 46 to move backward and compress the elastic member 45 until the position where the card slot 431 of the sliding locking pin 43 reaches the fixing rod 461. The elastic member 45 pushes the locking pin 46 to move forward, causing the fixing rod 461 to move forward and snap into the card slot 431, thereby locking and fixing the sliding locking pin 43.

[0044] In an embodiment of the present utility model, the center line of the second ear hole 21 is located in a plane perpendicular to the length direction of the watch band, and the center line of the second ear hole 21 is inclined from the opening towards the upper surface direction of the second side bead 20. In this way, when disassembling the bead assembly, after the first needle head 411 of the first telescopic pin head 41 is pushed by the sliding locking pin 43 to retract into the middle bead 30, only by pressing the middle bead 30 upwards (i.e., applying a force towards the upper surface direction of the middle bead 30), the second needle head 421 of the second telescopic pin head 42 can be retracted into the middle bead 30, and the middle bead 30 can be removed from the adjacent bead assembly.

[0045] Of course, in practical applications, the center line of the second ear hole 21 can also be inclined from the opening towards the upper surface direction of the second side bead 20. When disassembling the bead assembly, after the first needle head 411 of the first telescopic pin head 41 is pushed by the sliding locking pin 43 to retract into the middle bead 30, only by pressing the middle bead 30 downwards (i.e., applying a force towards the lower surface direction of the middle bead 30), the second needle head 421 of the second telescopic pin head 42 can be retracted into the middle bead 30, and the middle bead 30 can be removed from the adjacent bead assembly.

[0046] As Figure 5 shown, in an embodiment of the present utility model, the free ends of the first needle head 411 and the second needle head 421 respectively have conical surfaces. Correspondingly, a first sloping groove 12 connected to the lower surface of the first side bead 10 is provided below the first ear hole 11, and a second sloping groove 22 connected to the lower surface of the second side bead 20 is provided below the second ear hole 21. The sloping groove refers to a groove whose bottom wall is composed of an inclined surface connecting the side surface and the lower surface of the side bead. When assembling adjacent bead assemblies together, only by respectively abutting the first needle head 411 and the second needle head 421 protruding from the two side walls of the middle bead 30 against the bottom walls of the first sloping groove 12 and the second sloping groove 22, and pressing upwards forcefully, the first needle head 411 and the second needle head 421 can be retracted into the middle bead 30. When the first needle head 411 and the second needle head 421 reach the openings of the first ear hole 11 and the second ear hole 21, they are inserted into the first ear hole 11 and the second ear hole 21 under the action of the elastic member 45.

[0047] In an embodiment of the present utility model, the head end of the sliding locking pin 43 has a pin head 432, and the dimension of the pin head 432 along the length direction of the watch band is greater than the dimension of the second through hole 32 along the length direction of the watch band, so that the pin head 432 will not be embedded into the second through hole 32; moreover, a groove 33 is provided on the lower surface of the middle bead 30 (the groove 33 can be adjacent to one side wall of the middle bead 30), the second through hole 32 penetrates from the bottom of the groove 33 to the first through hole 31, and the depth of the groove 33 is greater than or equal to the height of the pin head 432 of the sliding locking pin 43 (i.e., the axial dimension of the sliding locking pin 43). In this way, it can be avoided that the pin head 432 of the sliding locking pin 43 protrudes from the surface of the middle bead 30, and the comfort of wearing the watch is improved.

[0048] As Figure 5 shown, in order to avoid gaps between adjacent bead components after assembly, in an embodiment of the present utility model, the rear end face of the middle bead 30 has a groove 34 provided along the width direction of the watch band. At the same time, the front end face of the middle bead 30 has a rib 35 provided along the width direction of the watch band. And when two bead components are connected, the rib 35 of the rear bead component is embedded into the groove 34 of the front bead component.

[0049] In addition, the rear end of the upper surface of the middle bead 30 has a flange, and the front end of the upper surface of the middle bead has an avoidance groove. And when two bead components are connected, the flange of the front bead component is embedded into the avoidance groove of the rear bead component.

[0050] The present utility model also provides a watch, including a watch dial and the single-press pin fast-release watch band as described above.

[0051] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
