DETAILED DESCRIPTION

[0054] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, the specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description only represent some embodiments of the present application, and those skilled in the art can obtain other drawings and other embodiments according to these drawings without creative labor.

[0055] In order to make the drawing simple, only the parts related to the present application are shown in each drawing, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the components with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one".

[0056] It is known that in the watch industry, basically, a watch band of a certain length is used as a component for fixing a watch on a wrist; because the wrist of a person has different tightness requirements for the watch band under cold, hot, dry, wet and other conditions, wearing a fixed length watch band needs to be adjusted repeatedly in length under these scenarios to maintain the comfort of wearing. At present, the watch bands on the market basically adjust their length by disassembling the watch grains, replacing the fixing holes and other methods. When operating, the watch needs to be removed from the wrist first, and then tools are used for adjustment. This adjustment method not only has high operation difficulty, but also has a large length span of the watch band before and after adjustment, and the length is difficult to adapt to the size of the user's wrist, so that the corresponding watch has poor wearing comfort.

[0057] To this end, with reference to the drawings of the specification Figures 1 to 6 In one embodiment, a watch band head grain is provided for reducing the adjustment difficulty of the watch band length, reducing the length span of the watch band before and after adjustment, and improving the use convenience and wearing comfort of the corresponding watch. With reference to Figure 1 And Figure 2 It comprises a first head grain 1 and a second head grain 2 in sliding connection with the first head grain 1, wherein the first head grain 1 is provided with a mounting groove 11 along the length direction of the watch band, and the bottom wall of the mounting groove 11 is provided with a first magnet 3; the second head grain 2 is reciprocally inserted into the mounting groove 11 along the length direction of the watch band and is detachably connected with the first head grain 1; correspondingly, the end of the second head grain 2 is provided with a second magnet 4, and when the second head grain 2 is completely inserted into the mounting groove 11, the second magnet 4 is in magnetic attraction with the first magnet 3 to reduce the combined length of the first head grain 1 and the second head grain 2, i.e. to limit the minimum combined length of the first head grain 1 and the second head grain 2; at the same time, a limiting assembly is arranged between the first head grain 1 and the second head grain 2, which is used to connect the first head grain 1 and the second head grain 2 and limit the second head grain 2 from being pulled out of the mounting groove 11, so as to limit the maximum combined length of the first head grain 1 and the second head grain 2.

[0058] In actual application, the user pulls the watch band according to his own needs, so that the second head grain 2 slides relative to the first head grain 1 until the limiting assembly limits the second head grain 2 from moving further; or the user pushes the watch band, so that the second head grain 2 slides relative to the first head grain 1 until the first magnet 3 attracts the second magnet 4, so as to realize the adjustment of the length of the watch band. The whole length adjustment process does not need to remove the watch from the wrist, thereby replacing the operation of adjusting the length of the watch band by disassembling the watch grains, replacing the fixing holes and other methods in the related art. The length adjustment operation of the watch band has low difficulty and is convenient to operate; at the same time, since the first head grain 1 and the second head grain 2 are in sliding connection, the length of the watch band only fluctuates in a small preset range, so that the size span of the length of the watch band before and after adjustment is small, which is more suitable for the size of the user's wrist, and effectively improves the wearing comfort of the corresponding watch.

[0059] In one embodiment, based on the above embodiment, specifically. With reference to Figures 1 to 3To reduce the production difficulty, in the embodiment, the first head grain 1 is provided in a split structure, including a base 12 and a cover plate 13, and the base 12 and the cover plate 13 are both generally in a T-shaped structure. Among them, one side of the base 12 in the thickness direction is adapted to the shape of the cover plate 13 and is recessed inward to form a buckling groove 121 for embedding the cover plate 13, that is, the depth direction of the buckling groove 121 is consistent with the thickness direction of the base 12; when assembled, the cover plate 13 is embedded into the buckling groove 121 along the depth direction of the buckling groove 121 and slides relative to the inner wall of the buckling groove 121 until the bottom wall abuts against the bottom wall of the buckling groove 121, realizing the buckling with the base 12; to realize the stable connection of the two, in the embodiment, the fitting mode of the cover plate 13 and the inner wall of the buckling groove 121 is all tight fitting connection. After the two are buckled, the mounting groove 11 is formed between the two.

[0060] In the embodiment, for the convenience of the following description, it is stipulated that the sliding direction of the first head grain 1 relative to the second head grain 2 is the length direction of the watchband head grain, and it is stipulated that the length directions of the first head grain 1, the second head grain 2, the buckling groove 121 and the mounting groove 11 are all consistent with the length direction of the watchband head grain.

[0061] Of course, to improve the structural strength of the first head grain 1, other structure forms can also be added; for example, referring to Figure 2 and Figure 3 , the base 12 is provided with a connecting groove 122 on the bottom wall of the buckling groove 121 (i.e., on the side wall of the mounting groove 11 of the base 12), and at least one connecting groove 122 is formed on the two side walls of the buckling groove 121 in the length direction (i.e., on the two inner walls in the length direction of the mounting groove 11), and any connecting groove 122 is in communication with the buckling groove 121; correspondingly, the cover plate 13 is provided with a connecting block 131 corresponding to the connecting groove 122, and when assembled, any connecting block 131 is slidably embedded into the corresponding connecting groove 122 along the depth direction of the buckling groove 121 until the cover plate 13 abuts against the bottom wall of the buckling groove 121. Similarly, the fitting mode of the connecting block 131 and the inner wall of the corresponding connecting groove 122 is also tight fitting connection.

[0062] Referring to Figure 2 and Figure 3In the embodiment, a plurality of insertion slots are formed on the end wall of the base 12 away from the second head grain 2 in the length direction of the mounting groove 11, and form the first mounting position 123. The first magnet 3 is sequentially inserted into the corresponding first mounting position 123 along the depth direction of the buckling groove 121, and is mounted on the first head grain 1. Correspondingly, a plurality of insertion holes are formed through the second head grain 2 in the thickness direction, and form the second mounting position 21 for mounting the second magnet 4. The second magnet 4 is inserted into the second mounting position 21 along the thickness direction of the second head grain 2, and is mounted on the second head grain 2. The connection relationship between the first magnet 3 and the insertion slot of the first mounting position 123, and the connection relationship between the second magnet 4 and the insertion hole of the second mounting position 21 are both tight fit connections. After the assembly of the watchband head grain, the side of the cover plate 13 close to the base 12 abuts against the same end surface of the first magnet 3 and the second magnet 4, thereby stably mounting the first magnet 3 and the second magnet 4. Of course, in order to improve the connection strength of the first head grain 1 and the second head grain 2, the cross section of any insertion slot or insertion hole can be T-shaped in the embodiment, and of course, other shapes can also be provided. The application is not limited thereto. Figure 3 Only the insertion hole structure with a T-shaped cross section is shown.

[0063] The limiting assembly includes a sliding groove 22 and a limiting plate 132. Referring to Figure 2 and Figure 4 , the sliding groove 22 is formed on the second head grain 2, and the length direction thereof is parallel to the length direction of the second head grain 2. The opening of the sliding groove 22 faces the side of the cover plate 13, and is in communication with the buckling groove 121 and the connecting groove 122. The limiting plate 132 is formed on the side of the cover plate 13 close to the base 12, and is vertically arranged at the opening of the mounting groove 11. After the assembly of the watchband head grain, the limiting plate 132 is inserted into the sliding groove 22 along the depth direction of the sliding groove 22. When the length of the watchband is adjusted, the limiting plate 132 slides along the length direction of the sliding groove 22 relative to the inner wall of the sliding groove 22, until the two sides of the thickness of the limiting plate 132 abut against the two inner wall surfaces of the sliding groove 22 in the length direction.

[0064] Further, in order to ensure the smoothness of the watchband length adjustment process, the embodiment preferably has a gas release groove 23 formed on the second head grain 2 in communication with the sliding groove 22. Specifically, the gas release groove 23 is located at one end of the sliding groove 22 away from the first magnet 3, and one is arranged on each side in the width direction of the sliding groove 22. The gas release groove 23 is used to balance the pressure in the space on both sides of the limiting plate 132 in the sliding groove 22, and to reduce the sliding resistance of the limiting plate 132 relative to the inner wall of the sliding groove 22.

[0065] Further, in the embodiment, referring to Figure 2 and Figure 3A stabilizing assembly 5 is further arranged to assist the stable sliding of the second link 2 relative to the first link 1 and to stabilize the second link 2 at the maximum combined length point or the minimum combined length point. The stabilizing assembly 5 is arranged between the first link 1 and the second link 2. Specifically, the stabilizing assembly 5 includes a third magnet 51 and a fourth magnet 52. The inner walls of the length direction of the mounting groove 11 are each provided with a plurality of insertion slots to form a third mounting position 124. The two end walls of the width direction of the second link 2 are each provided with a plurality of insertion holes to form a fourth mounting position 24. The third magnet 51 is inserted into the third mounting position 124 along the depth direction of the buckle groove 121, and the fourth magnet 52 is inserted into the fourth mounting position 24 along the thickness direction of the second link 2. Of course, to improve the mounting stability of the third magnet 51 and the fourth magnet 52, the third magnet 51 and the third mounting position 124 are in a tight fit connection, and the fourth magnet 52 and the fourth mounting position 24 are in a tight fit connection. After the assembly of the watchband link, the side of the cover plate 13 close to the base 12 abuts against the same end face of the third magnet 51 and the first magnet 3 to realize the stable mounting of the third magnet 51 on the first link 1.

[0066] In addition, any third magnet 51 and the adjacent fourth magnet are arranged in sequence and staggered along the length direction of the watchband link, and the same end walls of the two are arranged in opposition. On the one hand, in combination with the principle of "same polarity repulsion" of the magnet, the separation resistance of the first magnet 3 and the second magnet 4 and the separation resistance of the limiting plate 132 and the inner wall of the slide groove 22 away from the second magnet 4 are increased, so that the watchband link can be stably kept at the maximum combined length point and the minimum combined length point, respectively, and the watchband link has two stable adjustment gears. At the same time, by using the principle of "same polarity repulsion" of the magnet, the second link 2 is always kept in the middle of the mounting groove 11, thereby reducing the probability of shaking, jamming, etc. during the sliding process of the second link 2 relative to the first link 1.

[0067] In addition, with reference to Figure 2 and Figure 4 The watchband link further includes a first knob 133 and a second knob 125, and a third knob 25 and a fourth knob 26. Specifically, the first knob 133 and the second knob 125 are respectively formed on the end of the cover plate 13 and the base 12 away from the first magnet 3, and both have a triangular cross section. The third knob 25 and the fourth knob 26 are respectively formed on the two sides of the thickness direction of the second link 2, and both are located on the end of the second link 2 away from the second magnet 4. When the second link 2 is completely inserted into the mounting groove 11, that is, after the magnetic attraction connection of the first magnet 3 and the second magnet 4, the third knob 25 and the fourth knob 26 abut against the corresponding mating surfaces on the first knob 133 and the second knob 125, respectively, to block the opening of the mounting groove 11 and form the overall appearance of the watchband link. In this way, the production efficiency of the watchband link is effectively improved, the service life is prolonged, and the overall appearance is improved.

[0068] The technical principles of the present application are further described below by taking the application of the watchband head particle in a specific watchband as an example.
