The second ear 4a is rotatably connected to the second ear hole 2c on the second strap 2 closest to the third end 2a, and the second magnetic attraction component 4b is adsorbed and connected to the first magnetic attraction component 3b.

[0129] Specifically, the watch strap may refer to a watch strap with certain softness and deformation ability, for example, the material of the watch strap may be soft rubber, leather, etc. Preferably, the material of the watch strap may be soft rubber, which is more skin-friendly, more comfortable to wear, and has better softness and wear resistance.

[0130] For example, Figure 6 and Figure 7 As shown, the first strap mentioned above is provided with 6 first ear holes 1c, and the first end 1a of the first strap 1 is located at Figure 6 The left side of the second end 1b of the first strap 1 is along Figure 6 At one end in the right direction, the first ear hole 1c located closest to the second end of the first strap a is connected to the first magnetic buckle 3. Similarly, the second strap 2 mentioned above is provided with 6 second ear holes 2c, and the third end 2a of the second strap 2 is located at Figure 7 The fourth end 2b of the second strap 2 is along the left side. Figure 7 At one end on the right side, the second ear hole 2c located closest to the second end of the first strap a is connected to the second magnetic buckle 5.

[0131] It can be seen that, by adopting the present solution, the first magnetic buckle 3 and the second magnetic buckle 4 can be used to connect with the first ear hole and the second ear hole, thereby providing connection positions for the first magnetic buckle 3 and the second magnetic buckle 4 at different length positions of the first strap 1 and the second strap 2. In this way, when the user uses the strap for the first time, the position between any two first ear holes 1c on the first strap 1 and / or the position between any two second ear holes 2c on the second strap 2 can be cut, and after cutting, there is a first ear hole 1c closest to the second end 1b of the first strap 1 for connecting with the first magnetic buckle 3, and there is a second ear hole 2c closest to the third end 2a of the second strap 2 for connecting with the second magnetic buckle 4, thereby adjusting the wearing length of the strap to match the user's wrist size. When the user uses the strap subsequently, there is no need to adjust the wearing length of the strap again, and the watch can be worn quickly, which improves the user experience. When wearing the strap, it can be adsorbed and connected by the first magnetic buckle 3 and the second magnetic buckle 4, which is relatively simple to operate, and multiple wearings will not cause the strap to be worn and cause accelerated aging.

[0132] like Figure 6 and Figure 7 As shown, optionally, the plurality of first ear holes 1c are arranged at equal intervals on the first strap 1, and the plurality of second ear holes 2c are arranged at equal intervals on the second strap 2. Compared with the arrangement without spacing, the cut strap may be too long or too short and cannot completely match the user's wrist size. The design of equal spacing allows the user to cut the first strap 1 and the second strap 2 to a wearing length suitable for the user's wrist size, thereby improving the wearing comfort of the strap.

[0133] Further, in order to respectively set a plurality of first ear holes 1c and a plurality of second ear holes 2c on the first strap 1 and the second strap 2, the first strap 1 includes a plurality of first strap sections 11 connected in sequence, each of which is provided with a first ear hole 1c, and the second strap 2 includes a plurality of second strap sections 21 connected in sequence, each of which is provided with a first and second ear holes 2c. Specifically, the positions of the first ear holes 1c on each first strap section 11 are the same, and the positions of the second ear holes 2c on each second strap section 21 are the same, so that the plurality of first ear holes 1c on the first strap 1 are arranged at equal intervals, and the plurality of second ear holes 2c on the second strap 2 are arranged at equal intervals.

[0134] Optionally, the structure and size of each first strap section 11 are the same, and the structure and size of each second strap section 21 are also the same, so that the decorative effect of the appearance of the strap can be improved.

[0135] Optionally, each first strap section 11 is approximately in the shape of a long strip, and the first ear hole 1c is respectively provided at both ends of the first strap section 11 along the length direction, and the first ear hole 1c is arranged at both ends of the first strap section 11, so that the connection between the first ear hole 1c and the first magnetic buckle 3 can be facilitated.

[0136] Similarly, each second strap section 21 is approximately in the shape of a long strip, and the second ear holes 2c are respectively provided at both ends of the second strap section 21 along the length direction, and the second ear holes 2c are arranged at the two ends of the second strap section 21, so that the second ear holes 2c can be conveniently connected to the second magnetic buckle 4.

[0137] Optionally, two adjacent first strap sections 11 may be connected together by direct connection or indirect connection, and two adjacent first strap sections 11 may be connected together by snap connection, bonding, integral molding, etc. to form a complete first strap 1.

[0138] Similarly, two adjacent second strap sections 21 can be connected together by direct connection or indirect connection, and two adjacent second strap sections 21 can be connected together by snap connection, bonding, integral molding, etc. to form a complete second strap 2.

[0139] In this embodiment, if Figure 6 As shown, the first strap 1 further includes a plurality of first transition portions 12, both ends of each first transition portion 12 are respectively connected to two adjacent first strap sections 11, and are located between two adjacent first strap sections 11, as shown in FIG. Figure 7 As shown, the second strap 2 further includes a plurality of second transition portions 22, the two ends of each second transition portion 22 are respectively connected to two adjacent second strap sections 21, and are located between two adjacent second strap sections 21. The first transition portion 12 and the second transition portion 22 can be used to connect two adjacent first strap sections 11 and second strap sections 21.

[0140] Optionally, the projection of each first transition portion 12 on the first strap section 11 connected thereto is located within the first strap section 11, and the projection of each second transition portion 22 on the second strap section 21 connected thereto is located within the second strap section 21. In other words, the first transition portion 12 will not protrude from the first strap section 11 in any direction, and the second transition portion 22 will not protrude from the second strap section 21 in any direction, so that when the user wears the watchband, the first strap section 11 of the first strap 1 and the second strap section 21 of the second strap 2 fit the user's wrist, thereby improving the wearing comfort of the watchband in terms of the fit between the watchband and the user's wrist.

[0141] Optionally, the first transition portion 12 and the first strap section 11 can be integrally formed, and the second transition portion 22 and the second strap section 21 can be integrally formed, and the molding method can be injection molding or overmolding. The molding process is relatively simple, which can reduce the production cost of the strap and improve the production efficiency of the strap.

[0142] Furthermore, the first transition portion 12 and the second transition portion 22 are in the shape of a long strip, and the first transition portion 12 is provided with a Figure 6 The first through groove 12a is provided in the upper and lower surfaces of the paper, and the first through groove 12a separates the first transition part 12 into two parts. The second transition part 22 is provided with a second through groove 22a running through the upper and lower surfaces thereof, and the second through groove 22a separates the second transition part 22 into two parts.

[0143] When the user wears the watch strap, the first through groove 12a and the second through groove 22a are relatively breathable at the positions corresponding to the user's wrists, preventing the situation in which the position where the watch strap is worn on the wrist is not breathable and causing discomfort to the user when the user sweats or wears the watch strap for a long time. The above design can improve the wearing comfort of the watch strap in terms of the breathability of the watch strap.

[0144] Furthermore, in order to further improve the air permeability of the watchband, there is a distance between the lower surface of the first transition portion 12 and the plane where the lower surface of the first watchband section 11 connected thereto is located, and there is a distance between the lower surface of the second transition portion 22 and the plane where the lower surface of the second watchband section 21 connected thereto is located. That is to say, when the user wears the watchband, only the lower surfaces of the first watchband section 11 and the second watchband section 21 fit the user's wrist, while there is a distance between the lower surfaces of the first transition portion 12 and the second transition portion 22 and the user's wrist, further improving the wearing comfort of the watchband from the aspect of the air permeability of the watchband.

[0145] In this embodiment, if Figure 8 and Fig. 9As shown, in order to respectively set the first ear 3a and the first magnetic attraction component 3b and the second ear 4a and the second magnetic attraction component 4b on the first magnetic buckle 3 and the second magnetic buckle 4, the first magnetic buckle 3 includes a main shell 31, the main shell 31 includes a bottom plate 311 and two side plates 312, the two side plates 312 are respectively arranged on both sides of the bottom plate 311, and extend from one end of the bottom plate 311 to protrude from the other end of the bottom plate 311, the first magnetic attraction component 3b is arranged on the bottom plate 311, the first ear 3a is connected to the position where the two side plates 312 protrude from the bottom plate 311, and is located between the two side plates 312. The second magnetic buckle 4 includes a first shell 41 and a convex strip 42 protruding from one end of the first shell 41, the second magnetic attraction component 4b is arranged on the first shell 41, the convex strip 42 includes a first surface 42a facing away from the first shell 41, the first surface is provided with a groove 421, and the second ear 4a is arranged in the groove 421. That is to say, a first rotation space is formed between the positions where the two side plates 312 protrude from the bottom plate 311, and the second end 1b of the first strap 1 can rotate in the first rotation space, and a second rotation space is formed in the groove 421, and the third end 2a of the second strap 2 can rotate in the second rotation space.

[0146] Therefore, when the first magnetic buckle 3 and the second magnetic buckle 4 are connected to the first watchband 1 and the second watchband 2 respectively, the first and second magnetic buckles 3 and 4 can be used to hide the first and second ears 3a and 4a. On the one hand, the structure of the watchband can be made simpler and its appearance decorative effect can be improved. On the other hand, the first and second ears 3a and 4a can be prevented from being scratched or damaged when worn by the user due to the protruding design.

[0147] Furthermore, if Figure 4 and Fig. 9 As shown, the first magnetic buckle 3 also includes a sub-shell 32, the sub-shell 32 is arranged on the bottom plate 311, and the two sides of the sub-shell 32 are respectively fixedly connected to the two side plates 312, and there is a distance between the sub-shell 32 and the first ear 3a. The first magnetic attraction component 3b is arranged on the sub-shell 32, and the convex strip 42 protrudes upward from the top surface of the first shell 41 and protrudes to the two sides of the first shell 41. Figure 3 As shown, the convex strip 42 further includes a second surface 42b connected to and adjacent to the first surface 42a, and the second surface 42b is oriented in the same direction as the bottom surface of the first shell 41, and the groove 421 is disposed through the second surface 42b. Figure 8As shown, the side panel 312 includes a first portion 312a and a second portion 312b. The first portion 312a is disposed on the bottom plate 32, and its projection on the bottom plate 32 is located inside the bottom plate 32. The second portion 312b extends outward from the first portion 312a and protrudes from the bottom plate 32. The width of the second portion 312b is greater than that of the first portion 312a, and the connection between the two is arc-shaped.

[0148] It can be understood that when the second end 1b of the first strap 1 rotates in the first rotation space, it avoids interference with the sub-shell 32 and the bottom plate 311 to cause damage. The design of the groove 421 penetrating downward through the second surface makes it possible for the third end 2a of the second strap 2 to rotate in the second rotation space, so as to avoid interference with the ridge 42 to cause damage, thereby extending the service life of the strap.

[0149] It can be known that when the strap is worn on the user's wrist, the strap needs to be wrapped into a ring shape that matches the user's wrist. This is achieved through the softness of the first strap 1 and the second strap 2 and the first magnetic buckle 3 and the second magnetic buckle 4 are respectively connected to the first strap 1 and the second strap 2 for rotation. The present application uses the design that the second part 312b of the two side panels 312 protrudes from the other end of the bottom plate 311 and the groove 421 passes through the second surface downward, so that the second end 1b of the first strap 1 and the third end 2a of the second strap 2 will not interfere with the bottom plate 311 or the convex strip 42 when they are rotated downward relative to the first magnetic buckle 3 and the second magnetic buckle 4, and can be rotated at a larger angle, thereby maximizing the matching degree between the ring shape formed by the strap and the user's wrist, thereby improving the wearing comfort of the strap.

[0150] In this embodiment, combined with Figure 2 and Figure 3 As shown, the auxiliary housing 32 is located on the first housing 41, the bottom surface of the auxiliary housing 32 is arranged toward the first housing 41, the first magnetic component 3b is arranged on the bottom surface of the auxiliary housing 32, the top surface of the first housing 41 is arranged in contact with the bottom surface of the auxiliary housing 32, and the second magnetic component 4b is arranged on the top surface of the first housing 41 corresponding to the first magnetic component 3b. That is to say, when the first magnetic component 3b is adsorbed and connected with the second magnetic component 4b, the auxiliary housing 32 is superimposed on the first housing 41, and when the user wears the watchband, the contact area between the hard first magnetic buckle 3 and the second magnetic buckle 4 and the user's wrist is reduced as much as possible, that is, the contact area between the soft first strap 1 and the second strap 2 and the user's wrist is increased, thereby improving wearing comfort.

[0151] Specifically, Figure 8As shown, the second part 312b of the side panel 312 protrudes downward from the bottom surface of the auxiliary shell 32, and the convex strip 42 protrudes upward from the top surface of the first shell 41. The overall thickness of the main shell 31 and the auxiliary shell 32 stacked on the first shell 41 is approximately the same as the convex strip 42 and the second part 312b, so that the overall thickness of the first magnetic buckle 3 and the second magnetic buckle 4 of the present application when adsorbed and connected is smaller, which is similar to the thickness of the first watchband section 11 and the second watchband section 21, thereby making the overall thickness of the watchband more uniform and more comfortable for users to wear.

[0152] In this embodiment, combined with Figure 3 and Figure 5 As shown, a protrusion 321 is provided in the auxiliary housing 32, and the end of the protrusion 321 protrudes outward from the bottom surface of the auxiliary housing 32. The first magnetic attraction component 3b is provided on the end surface of the end, and the end of the protrusion 321 is provided with a clamping portion 32a. Fig. 9 As shown, the top surface of the first shell 41 is provided with a clamping hole 411, and the second magnetic component 4b is arranged in the clamping hole 411. The hole wall of the clamping hole 411 is provided with a step portion that cooperates with the clamping portion 32a, and the clamping portion 32a is used to be clamped on the step portion. Specifically, the clamping hole 411 can be a blind hole, so that the second magnetic component 4b can be arranged at the bottom of the blind hole. That is to say, when the user wears the watch strap, the first magnetic buckle 3 and the second magnetic buckle 4 are adsorbed and connected with the second magnetic component 4b through the first magnetic component 3b, and can be clamped on the step portion through the clamping portion 32a, so that the connection is more tightened, preventing the watch strap from being separated from the user's wrist due to external force, for example, when the user performs strenuous exercise, the hand is swung greatly, or the watch strap is hit.

[0153] Furthermore, in order to facilitate the user to release the connection between the first magnetic buckle 3 and the second magnetic buckle 4 and take off the watchband from the wrist, the protrusion 321 is slidably arranged in the auxiliary housing 32, and the side plate 312 is convexly provided with a button 33, and the button 33 extends into the auxiliary housing 32 and is connected to the protrusion 321, and the button 33 is used to provide a pressing force to drive the protrusion 321 to slide relative to the auxiliary housing 32, so that the clamping portion 32a is separated from the step portion. In other words, the user can drive the protrusion 321 to slide relative to the auxiliary housing 32 by pressing the button 33 so that the clamping portion 32a is separated from the step portion, and because the adsorption force between the first magnetic attraction component 3b and the second magnetic attraction component 4b is small, after the clamping portion 32a is separated from the step portion, the user can easily separate the first magnetic buckle 3 and the second magnetic buckle 4, and realize the removal of the watchband from the wrist.

[0154] Furthermore, an elastic component is provided between the button 33 and the side surface, which is used to provide an elastic force to drive the protrusion 321 to slide relative to the auxiliary housing 32, so that the clamping portion 32a is clamped to the step portion. Specifically, the elastic component can be a spring. That is to say, when the user wears the watchband, he only needs to press the button 33 to make the protrusion 321 located in the clamping hole 411, and after releasing the button 33, the button 33 slides under the elastic force of the elastic component to drive the protrusion 321 to slide relative to the auxiliary housing 32, so that the clamping portion 32a is clamped to the step portion, so that the watchband can be worn, the operation is convenient and quick, and the user experience is better.

[0155] In this embodiment, FIG. 3 and FIG. Figure 4 As shown, in order to improve the flexibility of the first magnetic buckle 3 and the second magnetic buckle 4 to rotate relative to the first watchband 1 and the second watchband 2, the watchband further includes a first connecting component 5 and a second connecting component 6, the first connecting component 5 is provided with a third ear 5a and a third ear hole 5b, the second connecting component 6 is provided with a fourth ear 6a and a fourth ear hole 6b, the third ear 5a is rotatably connected to the first ear hole 1c on the first watchband 1 closest to the second end 1b, the first ear 3a is rotatably connected to the third ear hole 5b, the fourth ear 6a is rotatably connected to the second ear hole 2c on the second watchband 2 closest to the third end 2a, and the second ear 4a is rotatably connected to the fourth ear hole 6b. The first connecting component 5 and the second connecting component 6 improve the flexibility of the first magnetic buckle 3 and the second magnetic buckle 4 to rotate relative to the first watchband 1 and the second watchband 2, respectively, so that when the watchband is worn on the user's wrist, it can better match the user's wrist and improve wearing comfort.

[0156] Specifically, Fig.10 As shown, the first connecting member 5 is in the shape of a convex block, including a first main body portion 51 and a first extension portion 52 extending outward from the middle of the first main body portion 51, the first extension portion 52 is provided with a third ear hole 5b, and a first mounting groove 511 is provided on a side of the first main body portion 51 away from the first extension portion 52, and the first mounting groove 511 penetrates downwardly through the first main body portion 51, and the third ear 5a is arranged in the first mounting groove 511, as shown in FIG. Fig.11 As shown, the second connecting component 6 is in the shape of a convex block, including a second main body portion 61 and a second extending portion 62 extending outward from the middle of the second main body portion 61, the second extending portion 62 is provided with the fourth ear hole 6b, and the second main body portion 61 is provided with a second mounting groove 611 on a side away from the second extending portion 62, and the second mounting groove 611 penetrates downwardly through the second main body portion 61, and the fourth ear 6a is arranged in the second mounting groove 611.

[0157] In addition, although the first magnetic buckle 3 and the second magnetic buckle 4 have a certain degree of rotational flexibility relative to the first strap 1 and the second strap 2 respectively, in order to avoid the first magnetic buckle 3 and the second magnetic buckle 4 from rotating excessively flexibly, which may cause the magnetic buckles to rotate flexibly and fail to correspond when the user fastens and connects the two magnetic buckles, the first main body portion 51 of the present invention also has a first limiting surface 53, and the first limiting surface 53 is formed by extending the side edge of the first extension portion 52 toward the first strap 1 roughly along the oblique upward direction, so that the first limiting surface 53 forms a limiting surface when the first magnetic buckle 3 rotates outward, thereby preventing the first magnetic buckle 3 from continuing to rotate. movement; similarly, the second main body part 61 has a second limiting surface 63, and the second limiting surface 63 is formed by the side edge of the second extension part 62 extending roughly obliquely upward in the direction of the second strap 2, so that the second limiting surface 63 forms a limiting surface when the second magnetic buckle 4 rotates outward, preventing the second magnetic buckle 4 from continuing to rotate, thereby ensuring that the first magnetic buckle 3 and the second magnetic buckle 4 have rotation flexibility but will not flip more than 90° to cause the inner surface of the first magnetic buckle and the inner surface of the second magnetic buckle to flip to the outside, thereby avoiding the first magnetic buckle and the second magnetic buckle from rotating too flexibly and being difficult to buckle together, thereby facilitating the user's buckling operation.

[0158] An embodiment of the present invention provides a watch strap, wherein a plurality of first ear holes are evenly spaced and distributed from a first end to a second end of the first watch strap, and a plurality of second ear holes are evenly spaced and distributed from a third end to a fourth end of the second watch strap, thereby providing a plurality of connection positions for the first watch strap and the second watch strap to be connected to a first magnetic buckle and a second magnetic buckle respectively. In a scenario where a user needs to adjust the length of the watch strap, for example, when using the watch strap for the first time, the watch strap can be cut at a position between any two first ear holes on the first watch strap and / or at a position between any two second ear holes on the second watch strap, and after cutting, there is a plurality of connection positions on the first watch strap. The first ear hole closest to the second end is used to connect with the first magnetic buckle, and the second ear hole closest to the third end of the second strap is used to connect with the second magnetic buckle, so as to adjust the length of the first strap and the second strap to make the wearing length of the strap match the user's wrist size. When the user uses the strap subsequently, there is no need to adjust the wearing length of the strap again, and the watch can be worn quickly, which improves the user experience. When wearing the strap, it can be adsorbed and connected by the first magnetic buckle and the second magnetic buckle, which is easy to operate, and repeated wearing will not cause the strap to be worn and cause accelerated aging.

[0159] In addition, the two ends of each first transition portion are respectively connected between two adjacent first strap sections, the projection of the first transition portion on the first strap section connected to itself is located within the first strap section, and there is a spacing between the lower surface of the first transition portion and the plane where the lower surface of the first strap section connected to it is located, and the two ends of each second transition portion are respectively connected between two adjacent second strap sections, the projection of the second transition portion on the second strap section connected to itself is located on the second strap section, and there is a spacing between the lower surface of the second transition portion and the plane where the lower surface of the second strap section connected to it is located, so that the upper and lower surfaces and side surfaces of the first strap section all protrude from the first transition portion, and the upper and lower surfaces and side surfaces of the second strap section all protrude from the second transition portion, so that when the user wears the watchband, the strap section of the watchband is in contact with the user's wrist, and the transition portion of the watchband is spaced from the user's wrist, thereby reducing the contact between the watchband and the user's wrist, improving air permeability, and thus improving the wearing comfort of the watchband.

[0160] The present invention also provides a watch based on the watchband of the above embodiment, the watch comprising a watch body and the watchband, the watchband being connected to the watch body. The embodiment of the present invention provides a watch that a user can quickly wear, the wearing method is simple, and multiple wearings will not cause the watchband to be worn and cause accelerated aging of the watchband.

[0161] The embodiment of the present invention also provides a wrist ruler and a watchband assembly, which is another watchband based on the watchband of the above embodiment. By using the watchband and the wrist ruler together, the length of the watchband can be cut conveniently, quickly and accurately. More specifically, the watchband can be connected to a watch body to form a watch. In order to clearly illustrate the technical solution of the embodiment of the present invention, the structure of the watch and the wrist ruler is used as an example. Fig.12 and Fig.13 As shown, the watch comprises: a watch body 100, a first watch band 1 and a second watch band 2 respectively arranged on opposite sides of the watch body 100, and a connecting portion for connecting the first watch band 1 and the second watch band 2; the first watch band 1 and the second watch band 2 both have a length-adjustable portion M, and the lengths of the first watch band 1 and the second watch band 2 other than the length-adjustable portion M are equal. The connecting portion refers to the state of magnetically fastening and connecting the first magnetic buckle 3 and the second magnetic buckle 4 respectively connected to the first watch band 1 and the second watch band 2.

[0162] like Fig.14As shown, the present embodiment also provides a wrist ruler 300 used in conjunction with the watch and used to measure the length of the watch strap. The material of the wrist ruler 300 is a flexible material or a bendable material. The wrist ruler 300 includes a first length portion L1 and a second length portion L2. The first length portion L1 is arranged at one side of the second length portion L2 along its length direction, or the first length portion L1 is divided into two parts, which are arranged at both sides of the second length portion L2 along its length direction. The first length portion L1 is directly connected to the second length portion L2, and there is no overlap at the connection between the first length portion L1 and the second length portion L2. The length of the second length portion L2 is equal to the difference between the total length of the watch and the total length of the adjustable length portion M of the first strap 1 and the adjustable length portion M of the second strap 2. The first length portion L1 is evenly provided with a plurality of first engraved lines along its length direction.

[0163] It should be noted that, in the cuboid 300, the first length portion L1 is directly connected to the second length portion L2, and the connection between the first length portion L1 and the second length portion L2 does not overlap, which means that when the first length portion L1 and the second length portion L2 are straightened, Fig.14 As shown, the total length of the first length portion L1 and the second length portion L2 is equal to the sum of the length of the first length portion L1 and the length of the second length portion L2, rather than the total length of the first length portion L1 and the second length portion L2 being actually less than (the first length portion L1 and the second length portion L2 overlap at the connection) or greater than (the first length portion L1 and the second length portion L2 are indirectly connected via other connectors) the sum of the length of the first length portion L1 and the length of the second length portion L2.

[0164] The embodiment of the present invention provides a watch. Since the total length of the first length portion L1 and the second length portion L2 is equal to the sum of the length of the first length portion L1 and the length of the second length portion L2 by straightening the wrist ruler 300, and the length of the second length portion L2 is equal to the difference between the total length of the watch and the length of the adjustable length portion M in the watch strap, the first length portion L1 is evenly provided with a plurality of first scale lines along its length direction. Therefore, when measuring the wrist diameter, the length of the first length portion L1 can be measured through the first scale lines, and then the length of the first length portion L1 obtained by the measurement is evenly distributed to the adjustable length portion M of the first strap 1 and the second strap 2. Since the lengths of the parts of the first strap 1 and the second strap 2 other than the adjustable length portion M are equal, it is possible to ensure that the lengths of the first strap 1 and the second strap 2 are always equal, so that the connecting portion is as close to the middle of the wrist as possible, which is convenient for the user to remove and wear and can improve the user's experience during the wearing process.

[0165] In one embodiment of the present invention, Fig.14 and Fig.15 As shown, in the cuboid, the first length portion L1 is arranged at one side of the second length portion L2 along the length direction thereof, and the cuboid further comprises a gripping portion 5 arranged at the other side of the second length portion L2 along the length direction thereof. When measuring, as shown in FIG16 , by circling the cuboid 300, fitting the cuboid 300 to the wrist, and pinching the two ends of the cuboid 300, a suitable first scale line can be obtained. This facilitates the measurement of the wrist diameter with one hand.

[0166] In another embodiment of the present invention, Fig.13 , Fig.17 and Fig.18 As shown, a plurality of second scale lines are evenly arranged on the length-adjustable portion M of the first strap 1 along its length direction; a plurality of third scale lines are evenly arranged on the length-adjustable portion M of the second strap 2 along its length direction; the distance between any two adjacent first scale lines, the distance between any two adjacent second scale lines and the distance between any two adjacent third scale lines are all equal.

[0167] Here, along the extension direction of the first strap 1 from the watch body 100 to the connecting portion (eg Fig.15 The distance between the first second engraved line and the starting end of the length adjustable part M can be 0, that is, the first second engraved line is located at the starting end of the length adjustable part M, or it can be non-0, that is, the distance between the first second engraved line and the starting end of the length adjustable part M is equal to the distance between two adjacent second engraved lines. Similarly, along the extension direction of the second watchband 2 from the watch body 100 to the connecting portion (such as Fig.15 The distance between the first second score line and the starting end of the length adjustable portion M may be 0 or may not be 0. The first length portion L1 gradually moves away from the second length portion L2 along the extending direction (eg, Fig.15 As shown by the arrow a in the middle, the distance between the first engraved line and the starting end of the first length portion L1 may be 0 or may not be 0.

[0168] In one embodiment of the present invention, Fig.13 , Fig.14 and Fig.15 As shown, along the extension direction of the first strap 1 from the watch body 100 to the connecting part, the first second scale line is located at the starting end of the adjustable length part M; along the extension direction of the second strap 2 from the watch body 100 to the connecting part, the first third scale line is located at the starting end of the adjustable length part M; along the extension direction of the first length part L1 gradually away from the second length part L2, the first first scale line is located at the starting end of the first length part L1.

[0169] In the embodiment of the present invention, during measurement, if the measured first scale line is an odd-numbered first scale line along the extension direction of the first length portion L1 gradually away from the second length portion L2, the portion between the odd-numbered first scale line and the first first scale line is divided into an even number of length units (the portion between two adjacent first scale lines is one length unit). At this time, the even number of length units are evenly distributed to the first strap 1 and the second strap 2, so that the lengths of the first strap 1 and the second strap 2 are equal. If the measured first scale line is an even-numbered first scale line along the extension direction of the first length portion L1 gradually away from the second length portion L2, the portion between the even-numbered first scale line and the first first scale line is divided into an odd number of length units (the portion between two adjacent first scale lines is one length unit). At this time, when distributing, one more length unit is distributed to the first strap 1. By configuring the first strap 1 as a strap that goes around the top of the wrist, according to the difference between the actual center position of the wrist and the visual center position, the visual center position is biased towards the thumb direction (such as Fig.19 As shown in the figure, by increasing the length of the first strap 1 by one length unit and by reasonably setting the length of one length unit, the connecting part can be located at the actual center of the wrist as much as possible, which is more convenient for users to take off and wear and can enhance the user experience during the wearing process.

[0170] However, in the above process, no matter whether the first second scale line and the first third scale line are both located at the starting end of the adjustable length portion M, after measuring the wrist diameter, it is necessary to cut the first strap and the second strap by comparison according to the above principle, which is inconvenient to operate and prone to mistakes.

[0171] Based on this, in one embodiment of the present invention, Fig.13 As shown, on the first strap 1, each second engraved line is further provided with a first mark and a second mark, and the first mark and the second mark are respectively provided on opposite sides of the length-adjustable portion M along the length direction, and a plurality of the first marks are located on the same side, and a plurality of the second marks are located on the same side; Fig.13 As shown, on the second strap 2, a third mark and a fourth mark are also provided at each third scale line, and the third mark and the fourth mark are respectively provided on opposite sides of the adjustable length portion M along the length direction, and a plurality of the third marks are located on the same side, and a plurality of the fourth marks are located on the same side.

[0173] In the embodiment of the present invention, after measuring the wrist diameter, the fifth mark corresponding to the third scale line is found, and then a mark identical to or corresponding to the fifth mark is found, and the first strap 1 and the second strap 2 can be cut. There is no need to perform more complicated calculations such as accurate length measurement and allocation of specific cut lengths of the two straps, making the entire strap cutting process simple and accurate.

[0174] The first mark, the second mark, the third mark, the fourth mark and the fifth mark can be letter marks, symbol marks, digital marks, etc., respectively, and are not specifically limited here. As long as the fifth mark located in the odd-numbered rows is the same or corresponds to the second mark and the third mark along the extension direction of the first length portion L1 gradually away from the second length portion L2, and the extension direction of the first watch strap 1 from the watch body 100 to the connecting portion; along the extension direction of the first length portion L1 gradually away from the second length portion L2, and the extension direction of the second watch strap 2 from the watch body 100 to the connecting portion, except for the first first mark, the fifth mark located in the even-numbered rows is the same or corresponds to the first mark and the fourth mark.

[0175] In one embodiment of the present invention, the first identifier, the second identifier, the third identifier, the fourth identifier and the fifth identifier are all serial number characters, and are arranged in sequence and continuously along the extension direction of the first length portion L1 gradually away from the second length portion L2.

[0176] At this time, if the fifth mark is a letter mark, it can be a, b, c, d, e, f, g, h, j, k, etc. At this time, the first mark, the second mark, the third mark and the fourth mark can be the same as the fifth mark, that is, along the extension direction of the first length portion L1 gradually away from the second length portion L2, and the extension direction of the first watch band 1 from the watch body 100 to the connecting part, the fifth mark located in the odd-numbered rows is the same as the second mark and the third mark; along the extension direction of the first length portion L1 gradually away from the second length portion L2, and the extension direction of the second watch band 2 from the watch body 100 to the connecting part, except for the first first mark, the fifth mark located in the even-numbered rows is the same as the first mark and the fourth mark.

The third mark is a, c, e, g in sequence, and the fourth mark is b, d, f, h, k in sequence.

[0177] Of course, the first mark, the second mark, the third mark and the fourth mark can also correspond to the fifth mark, such as capital letters. In this case, along the extension direction of the first strap 1 from the watch body 100 to the connecting part, the second first mark is B, D, F, H, K, and the second mark is A, C, E, G. The third mark is A, C, E, G, and the fourth mark is B, D, F, H, K.

[0181] In the embodiment of the present invention, when the length of the first length portion L1 is measured to the position marked as 3, the row marked with 3 is found, and the first strap is displayed with 2 and 3, and the second strap is displayed with 3 and 4; at this time, whether it is 2 on the first strap 1 or 4 on the second strap 2, it does not affect the cutting of the straps, and the first strap 1 and the second strap 2 are equal in length after cutting, that is, the measured length of the first length portion L1 is evenly distributed to the first strap 1 and the second strap; and when the length of the first length portion L1 is measured to the position marked as 8, the row marked with 8 is found, and the first strap 1 is displayed with 7 and 8, and the second strap 2 is displayed with 8 and 9; at this time, whether it is 7 on the first strap 1 or 9 on the second strap 2, it does not affect the cutting of the straps, and the first strap 1 has one more section than the second strap 2 after cutting, that is, the extra part after the measured length of the first length portion L1 is evenly distributed is distributed to the first strap 1, so that the connecting part is located at the actual center position of the wrist as much as possible.

[0182] Further optional, such as Fig.13 As shown, on the first watch band 1, the first mark and the second mark are respectively arranged on the side of the corresponding second engraved line away from the watch body 100; on the second watch band 2, the third mark and the fourth mark are respectively arranged on the side of the corresponding third engraved line away from the watch body 100. After cutting, the corresponding marks can also be cut off.

[0183] In one embodiment of the present invention, Fig.12 and Fig.13 As shown, the material of the first strap 1 and the second strap 2 is soft chain material, and the first strap 1 and the second strap 2 include a plurality of chain links m1 connected in sequence; in the first strap 1, each second engraved line is arranged at the connection between two adjacent chain links m1; in the second strap 2, each third engraved line is arranged at the connection between two adjacent chain links m1.

[0184] That is, in the embodiment of the present invention, one link m1 is a length unit, and by reasonably setting the length of one link m1, the watch strap can be cut so that the connecting portion is located in the middle of the wrist as much as possible.

[0185] The connection portion may be a connection buckle detachably connected to the first strap 1 and the second strap 2, or a magnetic buckle.

[0186] In another embodiment of the present invention, the connecting portion is a magnetic buckle.

[0187] When the connecting portion is a magnetic buckle, there are several possible ways to connect the first strap 1 and the second strap 2 to the magnetic buckle.

[0188] In a first possible implementation, each of the links m1 is provided with a spring ear hole on the side along the extension direction of the first strap 1 and the second strap 2; the end links m1 of the first strap 1 and the second strap 2 are connected to the magnetic buckle through the spring ear hole and the spring ear. After cutting off one or more links m1, the links m1 at the ends of the first strap 1 and the second strap 2 can be connected to the magnetic buckle through the spring ear hole and the spring ear.

The cutting position can be shielded to maintain a beautiful appearance.

[0190] In another embodiment of the present invention, Fig.13 As shown, in the first watch strap 1, the first guide groove U1 is provided at the corresponding position of the second scale line, and the first guide groove U1 can guide the cutting along the second scale line during cutting; in the second watch strap 2, the second guide groove U2 is provided at the corresponding position of the third scale line, and the second guide groove U2 can guide the cutting along the third scale line during cutting.

[0191] The first guide groove U1 can be arranged on the same side as the second scale line or on the opposite side thereof, and the second guide groove U2 can be arranged on the same side as the third scale line or on the opposite side thereof, which are not specifically limited here.

[0192] The specific structures of the first guide groove U1 and the second guide groove U2 are not limited, as long as at least one groove wall of the first guide groove U1 can guide cutting along the second score line during cutting; and at least one groove wall of the second guide groove U2 can guide cutting along the third score line.

[0193] Optional, such as Fig.12 and Fig.13 As shown, the second engraved lines are all arranged on the back side of the first strap 1 corresponding to the watch body 100; the third engraved lines are all arranged on the back side of the second strap 2 corresponding to the watch body 100. The front side of the watch body 100 refers to the side of the watch body 100 used to display time.

[0194] In another optional embodiment of the present invention, Fig.13 As shown, on the first watchband 1, a through hole O penetrating through the thickness direction of the first watchband 1 is provided at the middle of the first engraved line;

[0195] On the second watchband 2, a through hole O is provided in the middle of the second engraved line, which runs through the thickness direction of the second watchband 2. The air permeability of the watch can be maintained.

[0196] On the other hand, an embodiment of the present invention provides a wrist ruler 300 for measuring the length of a watch strap. Fig.12 As shown, the watch includes a watch body 100, a first watch strap 1 and a second watch strap 2 respectively arranged on opposite sides of the watch body 100, and a connecting portion for connecting the first watch strap 1 and the second watch strap 2; the first watch strap 1 and the second watch strap 2 both have a length-adjustable portion M; Fig.14 As shown, the material of the wrist ruler 300 is a flexible material or a bendable material; the wrist ruler 300 includes a first length portion L1 and a second length portion L2, the first length portion L1 is arranged at one side of the second length portion L2 along the length direction thereof, or the first length portion L1 is divided into two parts, which are arranged at both sides of the second length portion L2 along the length direction thereof, the first length portion L1 is directly connected to the second length portion L2, and the connection between the first length portion L1 and the second length portion L2 does not overlap, and the length of the second length portion L2 is equal to the difference between the total length of the watch and the total length of the adjustable length portion M of the first strap 1 and the adjustable length portion M of the second strap 2; a plurality of first engraved lines are evenly arranged on the first length portion L1 along the length direction thereof.

[0197] Among them, it should be noted that the first length portion L1 is directly connected to the second length portion L2, and there is no overlap at the connection between the first length portion L1 and the second length portion L2, which means that when the first length portion L1 and the second length portion L2 are straightened, the total length of the first length portion L1 and the second length portion L2 is equal to the sum of the length of the first length portion L1 and the length of the second length portion L2, rather than the total length of the first length portion L1 and the second length portion L2 is actually less than (the first length portion L1 and the second length portion L2 are overlapped at the connection) or greater than (the first length portion L1 and the second length portion L2 are indirectly connected via other connecting parts) the sum of the length of the first length portion L1 and the length of the second length portion L2.

[0198] The embodiment of the present invention provides a wrist ruler 300 for measuring the length of a watch strap. The wrist ruler 300 can be used to measure the wrist diameter. When measuring the wrist diameter, the length of the first length portion L1 can be measured through the first scale line, and then the length of the first length portion L1 obtained by measurement is evenly distributed to the length adjustable portion M of the first strap 1 and the second strap 2. Since the lengths of the first strap 1 and the second strap 2 except the length adjustable portion M are equal, it is possible to ensure that the lengths of the first strap 1 and the second strap 2 are always equal, so that the connecting portion is located in the middle of the wrist as much as possible, which is convenient for users to remove and wear and can improve the user experience during the wearing process.

[0199] The fifth identifier may be a letter identifier, a symbol identifier or a number identifier, which is not specifically limited here and can be reasonably set according to actual needs in practical applications.

[0200] In one embodiment of the present invention, the fifth identifiers are all serial number characters, and are arranged in sequence and continuously along the extension direction of the first length portion L1 gradually away from the second length portion L2.

[0201] Among them, optional, such as Fig.14 As shown, the fifth identifiers are all numerical symbols, and along the extension direction of the first length portion L1 gradually away from the second length portion L2, the first fifth identifier is 1. That is, as shown in the figure, along the extension direction of the first length portion L1 gradually away from the second length portion L2, the fifth identifiers can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 in sequence.

[0202] In another embodiment of the present invention, Fig.14 and Fig.16As shown, the material of the cuboid 300 is cardboard material, and the position corresponding to each first score line on the cuboid 300 is preset with an indentation P. During measurement, by pinching the two ends of the cuboid 300, the cutting node position can be measured more accurately.

[0203] In another embodiment of the present invention, Fig.14 and Fig.16 As shown, on the wrist ruler 300, the second length portion L2 includes a first portion L21 corresponding to the watch body 100 and a second portion L22 and a third portion L23 connected to opposite sides of the first portion L21, and the second portion L22 and the third portion L23 are preset with stamps P at intervals along the length direction thereof.

[0204] In the embodiment of the present invention, a watch can be better simulated, so that when measuring, it is helpful to control the tolerance and adjust the position of the nodes, thereby improving the accuracy of the measurement.

[0205] The embodiment of the present invention provides a wrist ruler for measuring the wrist circumference of a user. The material of the wrist ruler 300 is a flexible material or a bendable material. The wrist ruler 300 includes a first length portion L1 and a second length portion L2 connected to each other, wherein the first length portion is used as a marking portion for measuring the wrist circumference of the user, and the first length portion is evenly provided with a plurality of first scale lines along its length direction, and the second length portion is used as a reserved length portion for measuring the wrist circumference of the user, and the length of the second length portion is smaller than the wrist circumference of the user. When using the wrist ruler, only the second length portion is used as the reserved length portion and the first length portion is used as the marking portion, that is, there is no need to specifically measure the length value of the wrist circumference, and only the wrist circumference and the position of the first scale line corresponding to the first length portion need to be obtained, and the wrist ruler can be matched with the watch strap to conveniently and accurately cut the watch strap.

[0206] The first length portion L1 is arranged on one side of the second length portion L2 along its length direction; or, the first length portion is divided into two parts along its length direction and arranged on both sides of the second length portion L2 along its length direction; the first length portion L1 and the second length portion L2 are directly connected, and there is no overlap at the connection between the first length portion L1 and the second length portion L2; the length of the second length portion L2 is equal to the total length of the watch minus the length of the adjustable length portion of the watch strap; the first length portion L1 is evenly provided with a plurality of first scale lines along its length direction.

[0207] For example, the flexible material may be silicone material, rubber material, paper material, leather material, etc.; the bendable material may be metal film material or cardboard material, etc. As long as the wrist ruler 300 made of any of the above materials can go around the wrist once, the wrist diameter can be measured.

[0208] It should be noted that the first length portion L1 and the second length portion L2 are directly connected, and there is no overlap at the connection between the first length portion L1 and the second length portion L2, which means that when the first length portion L1 and the second length portion L2 are straightened, the total length of the first length portion L1 and the second length portion L2 is equal to the sum of the length of the first length portion L1 and the length of the second length portion L2, rather than the total length of the first length portion L1 and the second length portion L2 is actually less than (there is an overlap at the connection between the first length portion L1 and the second length portion L2) or greater than (the first length portion L1 and the second length portion L2 are indirectly connected via other connecting members) the sum of the length of the first length portion L1 and the length of the second length portion L2.

[0209] An embodiment of the present invention provides a wrist ruler. Since the total length of the first length portion L1 and the second length portion L2 is equal to the sum of the length of the first length portion L1 and the length of the second length portion L2 by straightening the wrist ruler, and the length of the second length portion is equal to the difference between the total length of the watch and the length of the adjustable length portion of the watch strap, the first length portion L1 is evenly provided with a plurality of first engraved lines along its length direction. Therefore, when measuring, the length of the non-adjustable length portion or the length-invariable length portion of the watch is already taken into account, and only the length of the first length portion L1 needs to be measured, and the corresponding length can be cut on the adjustable length portion, thereby avoiding cutting errors caused by unstable factors such as the total length of the watch and the length of the connecting portion after the user measures the wrist diameter by himself; it can help the user to accurately cut the watch strap, so that the user can wear the watch more conveniently and quickly.

[0210] In an optional embodiment of the present invention, Fig.14 As shown, the first length portion L1 is connected to one side of the second length portion L2 along its length direction; the wrist ruler 300 also includes a gripping portion 20 connected to the other side of the second length portion L2 along its length direction. At the same time, when measuring, by circling the wrist ruler 300, fitting the wrist ruler 300 to the wrist, and pinching the two ends of the wrist ruler 300, a suitable engraved line can be obtained, and then the corresponding position on the watchband can be found and cut, which is convenient for measuring the wrist diameter with one hand.

[0211] Among them, optional, such as Fig.14 As shown, along the length direction of the second length portion L2, the width W of the gripping portion 20 is 20-30 mm. That is, the width W of the gripping portion 20 can be any value between 20 mm and 30 mm, for example, the width W of the gripping portion 20 can be 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, etc.

[0212] On this basis, in another embodiment of the present invention, the length of the first length portion L1 is 60-72 mm, the distance between any two adjacent first score lines is 5-6 mm, and the length of the second length portion L2 is 60-80 mm.

[0213] Among them, the length of the first length portion L1 can be any value between 60mm and 72mm, such as 60mm, 61mm, 62mm, 63mm, 64mm, 65mm, 66mm, 67mm, 68mm, 69mm, 70mm, 71mm, 72mm, 73mm, 74mm, 75mm, 76mm, 77mm, 78mm, 79mm, 80mm, etc.

[0214] The distance between any two adjacent first score lines may be any value between 5-6 mm, such as 5 mm, 6 mm, etc.

[0215] The length of the second length portion L2 can be any value between 60-80, such as 60mm, 61mm, 62mm, 63mm, 64mm, 65mm, 66mm, 67mm, 68mm, 69mm, 70mm, 71mm, 72mm, 73mm, 74mm, 75mm, 76mm, 77mm, 78mm, 79mm, 80mm, etc.

[0216] That is, the length of the second length portion L2 is equal to the length of the non-adjustable length portion or the length-constant length portion of the watch. The distance between any two adjacent first engraved lines is equal to the minimum adjustable length of the watch strap, and the length of the first length portion L1 is equal to the length of the adjustable length portion M.

[0217] In another embodiment of the present invention, Figure 14-18 As shown, the material of the cuboid 300 is cardboard material, and the position corresponding to each first score line on the cuboid 300 is preset with an indentation P. During measurement, by pinching the two ends of the cuboid 300, the cutting node position can be measured more accurately.

[0218] In another embodiment of the present invention, on the wrist ruler 300, the second length portion L2 includes a first portion 21 corresponding to the watch body and a second portion 22 and a third portion 23 connected to opposite sides of the first portion 21, and the second portion 22 and the third portion 23 are preset with stamps P at intervals along the length direction thereof.

[0219] In the embodiment of the present invention, a watch can be better simulated, so that when measuring, it is helpful to control the tolerance and adjust the position of the nodes, thereby improving the accuracy of the measurement.

[0220] In another embodiment of the present invention, Fig.14As shown, each first engraved line is provided with a first mark for identifying the first engraved line. Correspondingly, a second mark corresponding to the first mark can be provided at the corresponding position of the watch strap. After the measurement is completed, the second mark corresponding to the measured first mark can be directly found to obtain the cutting position, which is more convenient to operate.

[0221] The first identifier may be a letter identifier, a symbol identifier, etc., which is not specifically limited here.

[0222] In one embodiment of the present invention, the first identifiers are all serial number characters, and along the extension direction of the first length portion L1 gradually away from the second length portion L2, the first identifiers are arranged in sequence in sequence. For example, the first identifiers may be alphabetic characters, and along the extension direction of the first length portion L1 gradually away from the second length portion L2, the first identifiers may be a, b, c, d, e, f, g, h in sequence.

[0223] Optionally, the first identifiers are all numerical symbols, and along the extension direction of the first length portion L1 gradually away from the second length portion L2, the first first identifier is 1.

[0224] That is, Fig.14 As shown, along the extension direction of the first length portion L1 gradually away from the second length portion L2, the first marks are 1, 2, 3, 4, 5, 6, 7, ..., 10, 11, 12, 13 in sequence.

[0225] An embodiment of the present invention further provides a method for measuring wrist circumference, comprising the following steps: using a wrist ruler as in the above embodiment to fit a user's wrist, taking one end of the second length portion as a starting point, the wrist ruler wraps around the wrist and connects with the starting point, the first length portion is a first scale line at the point where it connects with the starting point, and the length between the starting point and the first scale line is the user's wrist circumference.

[0226] For example Fig.14 As shown, with the end of the second length portion L2 connected to the gripping portion 20 as the starting point, pinch the gripping portion 20 to make the wrist ruler wrap around the user's wrist, and then the first length portion L1 contacts the starting point. At this time, the intersection of the two, the first length portion is specifically located at the first engraved line where the first mark 8 is located, that is, the length between the starting point and the first mark 8 is the user's wrist circumference. The user does not need to measure the specific user's wrist circumference, nor does he need to calculate how much length the corresponding two sections of the watch strap need to be cut. He only needs to match and compare the first mark 8 with the watch strap with the corresponding mark 8, and he can quickly cut the watch strap with a suitable wrist circumference, which simplifies the measurement of wrist circumference and the cutting of the watch strap, and makes the adjustment of the watch strap length more accurate.

[0227] On the other hand, an embodiment of the present invention provides a watch. The watch further includes the wrist ruler 300 as described above.

[0228] The embodiment of the present invention provides a watch, because when the wrist ruler 300 in the watch is straightened, the total length of the first length portion L1 and the second length portion L2 is equal to the sum of the length of the first length portion L1 and the length of the second length portion L2, and the length of the second length portion L2 is equal to the difference between the total length of the watch and the length of the length-adjustable portion M in the watch strap, and the first length portion L1 is evenly provided with a plurality of first engraved lines along its length direction. Therefore, when measuring, the length of the non-adjustable portion or the length-invariable portion in the watch is taken into account, and only the length of the first length portion L1 needs to be measured, and the corresponding length can be cut on the length-adjustable portion M, thereby avoiding cutting errors caused by unstable factors such as the total length of the watch and the length of the connecting portion after the user measures the wrist diameter by himself; it can help the user to accurately cut the watch strap, so that the user can wear the watch more conveniently and quickly.

[0229] In one embodiment of the present invention, Figure 1 As shown, in the watch, only the first strap 1 has an adjustable length portion M; accordingly, in the wrist ruler 300, the first length portion L1 is connected to one side of the second length portion L2 along its length direction, and the adjustable length portion M is provided with a second scale line corresponding to the first scale line. The user uses the wrist ruler 300 to measure the wrist diameter to obtain a first scale line, find the second scale line on the corresponding strap, and directly cut the strap according to the second scale line, and then assemble the connecting part to complete the strap adaptation work.

[0230] In another embodiment of the present invention, when a first mark for marking the first scribed line is provided at each of the first scribed lines, as shown in FIG. Fig.13 As shown, each second scale line is provided with a second mark for identifying the second scale line, and the second mark is identical or corresponding to the first mark.

[0231] The user uses the wrist ruler 300 to measure the wrist diameter to obtain a first mark, finds the second mark on the corresponding strap that corresponds to the first mark, and directly cuts along the second scale line corresponding to the second mark on the strap, and then assembles the connecting part to complete the strap adaptation work, which is more convenient and quick to operate.

[0232] Among them, according to the first identifier, a corresponding second identifier can be set. For example, when the first identifier is a lowercase letter symbol, the second identifier can be the corresponding uppercase letter symbol; when the first identifier is a number, the second identifier can be the corresponding letter serial number; for example, when the first identifier is 1, the corresponding second identifier can be A, when the first identifier is 2, the corresponding second identifier can be B, and so on. When the first identifier is 5, the corresponding second identifier can be E.

[0233] In one embodiment of the present invention, Fig.13 As shown, the first identifiers are all numeric characters, and along the extension direction of the first length portion L1 gradually away from the second length portion L2, the first first identifier is 1; correspondingly, the second identifiers are all numeric characters, and along the extension direction of the first strap from the watch body to the connecting part, the second identifiers are identical to the first identifiers.

[0234] In this way, by measuring the first mark corresponding to the first scale, and then finding the second mark that is the same as the first mark, the watch strap can be cut. Fig.14 As shown, along the extending direction of the first length portion L1 gradually away from the second length portion L2 (as shown in FIG. Fig.15 The first identifiers are 1, 2, 3, 4, 5, ..., 10, 11, 12, 13 in sequence. Fig.15 As shown, Fig.15 In the direction indicated by the arrow b, the second identifiers are 1, 2, 3, 4, 5, and 6 respectively.

[0235] Another embodiment of the present invention discloses another cubit ruler, such as Figure 13-Figure 18 As shown, for measuring the wrist circumference of a user, the wrist ruler 300 includes a first length structure (i.e. Fig.12 L2 shown in ) and the second length structure (i.e. Fig.12 L1 shown in the figure), and the wrist ruler 300 is a bendable structure; wherein the first length structure L2 is used as a reserved length portion for measuring the user's wrist circumference, and the second length structure L1 is used as a marking portion for measuring the user's wrist circumference. The second length structure L1 is provided with a plurality of marking portions (i.e. Fig.12 ).

[0236] Specifically, the first length structure is equivalent to the length of the watch body, the second strap and the first strap except the length-adjustable portion M mentioned above. After the wrist ruler 300 is wrapped around the user's wrist for one circle, the length from the end of the second length structure to a certain marking portion on the first length structure is the wrist diameter of the wrist. The corresponding value of the user's wrist diameter can be obtained by reading the numerical mark of the marking portion there. Then, the corresponding value is matched with the corresponding mark on the second strap 2. The length from the corresponding mark on the second strap 2 to the end of the first strap 1 is the strap length matching the user.

[0237] Furthermore, if Fig.14 As shown, the first length structure L2 includes a simulated host part (i.e. Fig.14 L21 in) and the imitation strap part (i.e. Fig.14 L22 in the ), imitate the host part (ie Fig.14 L21 in) and the imitation strap part (i.e. Fig.14 The material of L22) is a flexible material or a bendable material.

[0238] Furthermore, the marking portion includes a score line L3 (i.e. Fig.14 The first scale line shown in FIG) and the mark corresponding to scale line L3 (i.e. Fig.14 When using the wrist ruler 300, only the first length portion structure is used as the reserved length portion and the second length portion structure is used as the marking portion, that is, there is no need to specifically measure the length value of the wrist circumference, and only the mark at the position where the wrist circumference and the corresponding engraved line of the second length portion structure are obtained, and the wrist ruler can be matched with the watch strap to conveniently and accurately cut the watch strap.

[0239] In this embodiment, the identification can be any of the following: numbers, letters, symbols, colors, and the identification is used for identification. In this embodiment, the identification is a number, and the marking portion on the second length structure L1 close to the first length structure L2 is the starting marking portion a1. The identification of the starting marking portion a1 is a number n, where n is a natural number greater than or equal to 1. From the second length structure L1 to the direction away from the first length structure L2, the numbers of the identifications on each marking portion increase in sequence, and the difference between the numbers of the identifications on two adjacent marking portions is 1. For example, in this embodiment, from the second length structure L1 to the direction away from the first length structure L2, the identification portions are 1, 2, 3, 4, 5, 6, 7, 8, 9 in sequence.

[0240] Furthermore, if Fig.14As shown, the engraved line L3 extends along the width direction of the cub 300, and the engraved line L3 includes a main line L31 and an end portion connected to one end of the main line L32, the line width of the end portion L32 is smaller than the line width of the main line L31, and the mark is set at the end portion L32. Specifically, by setting the line width of the end portion L32 to be smaller than the line width of the main line L31, the cub 300 is facilitated to bend.

[0241] Furthermore, if Fig.14 As shown, the first length structure L2 and the second length structure L1 both include wrist band segments Q connected in sequence and a connecting portion T connecting the wrist band segments Q, and the engraved line L3 and the logo are set on the connecting portion T of the second length structure L1. And the surface of at least one of the first length structure and the second length structure is concave at the connecting portion T so that an indentation is formed at the connecting portion T (i.e. Fig.14 The thickness at the connection portion T is smaller than the thickness at the wrist band section Q. The engraved line L3 covers the connection portion T.

[0242] Furthermore, if Fig.14 As shown, a pinching portion 20 is further provided on the side of the first length structure L2 away from the second length structure L1. In the embodiment of the present invention, the pinching portion 20 is provided to better simulate a watch, so that when measuring, it is helpful to control the tolerance and adjust the position of the nodes, thereby improving the accuracy of the measurement. The width of the pinching portion 20 is 20-30 mm. That is, the width of the pinching portion 20 can be any value between 20 mm and 30 mm. For example, the width of the pinching portion 20 can be 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, etc. Further, as Fig.14 As shown, the wrist ruler 300 is formed by pressing a flexible material in one piece. For example, the flexible material can be a silicone material, a rubber material, a paper material, a leather material, etc.; the bendable material can be a metal film material or a cardboard material, etc. As long as the wrist ruler 300 made of any of the above materials can be wrapped around the wrist, the wrist diameter can be measured.

[0243] The present application also discloses a wrist circumference measurement method, which uses the wrist ruler to measure the wrist circumference of the user, and further includes the following steps:

[0244] The wrist ruler 300 is wrapped around the wrist of the user being measured, with the end of the first length structure L2 away from the second length structure L1 as the starting point; the wrist ruler 300 is connected to the starting point after wrapping around the wrist of the user being measured, and the mark on the marking part from the connection with the starting point to the starting point on the second length structure L1 is the user's wrist circumference of the user being measured.

[0245] The present application also discloses a wrist ruler and watch strap assembly, including the wrist ruler 300 and a watch strap, see Fig.12 The watch strap includes: a first watch strap 1 and a second watch strap 2. The first watch strap 1 is used to connect one end of the watch host 100, including a first preset length portion N1 and a first cuttable portion M1 connected to the first preset length portion N1; the second watch strap 2 is used to connect the other end of the watch host 100, including a second preset length portion N2; wherein the first preset length portion N1 and the second preset length portion N2 are used as preset length portions worn on the user's wrist, the first cuttable portion M1 can be used as a cutting portion cut according to the user's wrist circumference, and a plurality of first cutting marking portions are provided on the first cuttable portion M1, and the user can cut the first cutting portion M1 after measuring the wrist diameter of the wrist. , according to the actual wrist diameter of the user, the first cutting mark portion that is consistent with the wrist diameter mark actually measured can be found on the first cutting mark portion, and then the first cutting mark portion can be cut at the first cutting mark portion. The longitudinal length of the watch host 100, the first preset length portion N1, the second preset length portion N2 and the total length of the first cutting portion M1 obtained after cutting are the actual wrist diameter of the user. Through the structural design of the watch strap, the user can accurately cut the watch strap according to his actual wrist diameter to obtain the length of the watch strap that matches his wrist size, and the operation is simple and quick.

[0246] Furthermore, in addition to cutting the first strap 1, the second strap 2 can also be cut, so that after cutting the first strap 1 and the second strap 2, the lengths of the first strap 1 and the second strap 2 are substantially equal, and the magnetic buckle of the strap can be located at the midline of the user's wrist. Fig.12 As shown, the second watchband 2 includes a second cuttable portion M2 connected to the second preset length portion N2. The second cuttable portion M2 can also be used as a cutting portion for cutting according to the user's wrist circumference. The second cuttable portion M2 is provided with a plurality of second cutting marking portions. After measuring the wrist diameter of the wrist, the user can find the first cutting marking portion and the second cutting marking portion that are consistent with the wrist diameter mark obtained by the actual measurement on the first cuttable portion M1 and the second cuttable portion M2 according to the actual wrist diameter of the user, and then cut the first cuttable portion M1 at the first cutting marking portion and cut the second shell cutting portion M2 at the second cutting marking portion. The longitudinal length of the watch host 100 obtained after cutting, the first preset length portion N1, the second preset length portion N2, the first cuttable portion M1 and the second cuttable portion M2 are the total lengths of the actual wrist diameter of the user. Through the structural design of the watchband, it is convenient for the user to accurately cut the watchband according to his actual wrist diameter to obtain the length of the watchband that matches his wrist size, and the operation is simple and quick.

[0247] In summary, according to the mark value of the measured wrist diameter, the first cutting mark part and the second cutting mark part that are consistent with the measured mark value can be found in the first cutting part M1 and the second cutting part M2 respectively, and the first cutting part M1 and the second cutting part M2 can be cut at the first cutting mark part and the second cutting mark part respectively. At this time, the lengths of the first watchband 1 and the second watchband 2 are roughly equal, so that the magnetic buckle of the watch with the watchband can be located at the center of the wrist, so that the user's wearing experience is better. For example, if the mark value obtained by measuring the wrist diameter is 6, the mark parts marked with 6 can be found in the first cutting part M1 and the second cutting part M2 respectively, and then the first cutting part M1 and the second cutting part M2 can be cut at the first cutting mark part and the second cutting mark part marked with 6.

[0248] Furthermore, if Fig.13 As shown, for the convenience of cutting, the first cutting mark portion and the second cutting mark portion both include cutting marks (i.e. Fig.13 The first mark, the second mark, the third mark and the fourth mark shown in FIG) and the cutting mark corresponding to the cutting mark (such as Fig.13 The second and third scale lines shown in FIG); wherein the cutting mark can be any one of the following: numbers, letters, symbols, the cutting mark is used for identification, and the cutting scale lines are used to indicate that cutting is to be performed along the cutting scale lines.

[0249] In this embodiment, if Fig.13 As shown, the cutting mark is preferably digital, which can be convenient for accurately locking the digital cutting mark consistent with the wrist diameter according to the wrist diameter measured by the user. It should be noted that, as shown in FIG13, the cutting mark line includes two parts spaced apart from each other, and the cutting mark is located between the two parts, so that the cutting mark can be clearly seen, and the cutting mark is located between the two parts, so when the first strap 1 or the second strap 2 is cut along the cutting mark line, the cutting mark will not be cut.

[0250] Furthermore, if Fig.13 As shown, the first cuttable portion M1 includes a plurality of first strap sections (i.e. Fig.13 The first connecting portion includes a first side m11 and a second side m12 which are arranged opposite to each other, the first side m11 and the second side m12 are respectively connected to the two adjacent first strap sections, and the first cutting mark portion is arranged on the first side m11 and the second side m12; the second cuttable portion M2 includes a plurality of second strap sections (i.e. Fig.13The chain link m1) and the second connecting portion connected between two adjacent second strap sections, the second connecting portion includes a third side m13 and a fourth side m14 arranged opposite to each other, the third side m13 and the fourth side m14 are respectively connected to two adjacent second strap sections, and the second cutting mark portion is arranged on the third side m13 and the fourth side m14.

[0251] For the cropping marks set on the first side m11, the second side m12, the third side m13, and the fourth side m14, the following setting examples may be referred to:

[0252] The example of the cutting mark set on the first side m11 is as follows: the first connection portion where the first cuttable portion M1 connects the first preset length portion N1 is the first starting connection portion, and the cutting mark on the first side m11 of the first starting connection portion is the number n-1. From the first cuttable portion M1 in the direction away from the first preset length 1 portion, the numbers of the cutting marks on the first side m11 of each first connection portion gradually increase, and the difference between the numbers of the cutting marks on two adjacent first side m11 is 2, where n is a natural number greater than or equal to 1. For example, in this embodiment, n is 1, and from the first cuttable portion M1 in the direction away from the first preset length 1 portion, the cutting marks on the first side m11 of each first connection portion are 0, 2, 4, 6, 8, 10 in sequence.

[0253] The example of the cutting mark set on the second side m12 is as follows: the cutting mark on the second side of the first starting connection portion is the number n, and from the first cuttable portion M1 in the direction away from the first preset length portion N1, the numbers of the cutting marks on the second side m12 of each first connection portion gradually increase, and the difference between the numbers of the cutting marks on the m12 of two adjacent second sides is 2. For example, in this embodiment, n is 1, and from the first cuttable portion M1 in the direction away from the first preset length 1 portion, the cutting marks on the second side m12 of each first connection portion are 1, 3, 5, 7, and 9 in sequence.

[0254] The example of the cutting mark set on the third side m13 is as follows: the second connection portion where the second cuttable portion M2 connects the second preset length N2 portion is the second starting connection portion, and the cutting mark on the third side m13 of the second starting connection portion is the number n. From the second cuttable portion M2 in the direction away from the second preset length portion N2, the numbers of the cutting marks on the third side m13 of each second connection portion gradually increase, and the difference between the numbers of the cutting marks on two adjacent third sides m13 is 2, where n is a natural number greater than or equal to 1. For example, in this embodiment, n is 1, and the cutting marks on the third side m13 of each second connection portion in the direction away from the second preset length portion N2 of the second cuttable portion M2 are 1, 3, 5, 7, and 9, respectively.

[0255] The examples of the cutting mark set on the fourth side m14 are as follows: the cutting mark on the fourth side of the second starting connection portion is the number n+1, and the numbers of the cutting marks on the fourth side m14 of each second connection portion gradually increase from the second cuttable portion M2 in the direction away from the second preset length portion N2, and the difference between the numbers of the cutting marks on two adjacent fourth sides m14 is 2. For example, in this embodiment, n is 1, and the second cuttable portion M2 is in the direction away from the second preset length portion N2, and the cutting marks on the third side m14 of each second connection portion are 2, 4, 6, 8, 10 in sequence.

[0256] In summary, in this embodiment, the cutting marks of the first side m11 are: 0, 2, 4, 6, 8, 10; the cutting marks of the second side m12 are: 1, 3, 5, 7, 9; the cutting marks of the third side m13 are: 1, 3, 5, 7, 9; and the cutting marks of the fourth side m14 are: 2, 4, 6, 8, 10.

[0257] For example, when the mark value obtained by measuring the wrist diameter with the wrist ruler 300 is 6, the corresponding number 6 is found on the cutting marks of the first side m11 and the second side m12, and the number 6 is found on the cutting marks of the third side m13 and the fourth side m14. Then, the first cuttable portion M1 and the second cuttable portion M2 are cut according to the cutting mark at the position marked with 6, and the final length of the watch strap is the length of the watch strap matching the wrist diameter of the user.

[0258] For another example, when the length of the second length structure L1 is measured to the position marked with the fifth mark 3, the row marked with 3 is found, and the first strap displays 2 and 3, while the second strap displays 3 and 4; at this time, whether it is 2 on the first strap 1 or 4 on the second strap 2, it does not affect the cutting of the straps, and the first strap 1 and the second strap 2 are the same length after cutting, that is, the measured length of the second length structure L1 is evenly distributed to the first strap 1 and the second strap; and when the length of the second length structure L1 is measured to the position marked with the fifth mark 8, the row marked with 8 is found, and the first strap 1 displays 7 and 8, while the second strap 2 displays 8 and 9; at this time, whether it is 7 on the first strap 1 or 9 on the second strap 2, it does not affect the cutting of the straps, and the first strap 1 has one more section than the second strap 2 after cutting, that is, the extra part after the measured length of the second length part L1 is evenly distributed is distributed to the first strap 1, so that the magnetic buckle of the watch is located at the actual center of the wrist as much as possible.

[0259] The purpose of such a setting is that when the wrist diameter measured by the user using the above-mentioned wrist ruler 300 is an even number, such as 6, the first strap 1 is only one more first strap section or the second strap section than the second strap 2 (the lengths of the first strap section and the second strap section are the same), and since the actual center position of the wrist is different from the visual center position, the visual center position is biased towards the thumb direction (as shown in FIG. 19 ). By increasing the length of the first strap 1 by one length unit and reasonably setting the length of one length unit, the connecting part can be located at the actual center position of the wrist as much as possible, which is more convenient for users to remove and wear and can enhance the user experience during the wearing process.

[0260] Furthermore, if Figure 1 , Fig.13 As shown, the first connecting portion also has a first opening (ie, Fig.13 The second connecting portion further has a second opening (i.e. Fig.13 U2), by cutting the first cuttable part M1 or the second cuttable part M2 at the first opening or the second opening, cutting can be facilitated.

[0261] In this embodiment, if Fig.13 As shown, the watch strap also includes a first connecting member, a first fixing member, a second connecting member and a second fixing member. The first watch strap section of the first cuttable portion M1 located at an end away from the first preset length portion N1 is a first terminating watch strap section m21.

The other end of the first connecting member n21 is connected to the first fixing member. The second watch strap section of the second cuttable portion M2 located at an end away from the second preset length N2 portion is a second terminating watch strap section m22. The second opening of the second terminating watch strap section m22 is used to be installed and connected to one end of the second connecting member n22. The other end of the second connecting member n21 is connected to the second fixing member. The second fixing member is also used to fix to the first fixing member so that the watch using the watch strap can be worn on the user's wrist.
