[0025] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] As Figures 1-4 shown, this is a schematic structural diagram of the double - press adjustment watch buckle provided by the embodiment of the present utility model. This double - press adjustment watch buckle can be assembled to a watchband and realize the connection of two watchbands. The double - press adjustment watch buckle of this embodiment includes a buckle base 10, a face cover 20, a telescopic toothed plate 30 and two adjustment buttons 40. Among them, the buckle base 10 and the telescopic toothed plate 30 can be respectively connected to the watchband 50. The telescopic toothed plate 30 is assembled to the face cover 20 in a manner that it can slide along the first direction, and the two adjustment buttons 40 are respectively assembled to the face cover 20 and can slide relative to the face cover 20 along the second direction. The above - mentioned first direction is the length direction of the watchband 50, and the second direction is the width direction of the watchband. Specifically, the above - mentioned buckle base 10 can be composed of a frame 11 and a core 12 hinged to one end of the frame 11. And the frame 11 is provided with a second watchband connection member 111 for connecting the watchband 50, and the core 12 is provided with a connection member 121 for connecting the face cover 20 and locking and fixing with the frame 11. In practical applications, the buckle base 10 can also adopt other existing structures, which will not be elaborated here.

[0027] The above - mentioned face cover 20 includes a receiving cavity. The receiving cavity is generally arranged along the length direction of the watchband 50, and the opening of the receiving cavity is located at one end of the face cover 20 in the first direction. One end of the face cover 20 facing away from the opening of the receiving cavity is installed on the buckle base 10. The telescopic toothed plate 30 includes two racks 31 respectively arranged along the first direction and a first watchband connection member 33 located at one end in the first direction and used for assembling the watchband. And one end of the telescopic toothed plate 30 facing away from the first watchband connection member 33 is inserted into the receiving cavity of the face cover 20. The above - mentioned first watchband connection member 33 can be specifically composed of a strap screw or any existing member for connecting the watchband. Those skilled in the art can understand that to ensure the stable movement of the telescopic toothed plate 30 in the receiving cavity along the first direction, the cross - section (perpendicular to the first direction) of the receiving cavity is preferably adapted to the cross - section of the telescopic toothed plate 30.

[0028] Each adjustment button 40 includes a pressing portion 41 and a tooth engaging portion 42. Specifically, the pressing portion 41 may be in the shape of a plate perpendicular to the second direction, and its length along the first direction is relatively long. The tooth engaging portion 42 has a block adapted to the gap between two adjacent teeth on the rack 31. The two adjustment buttons 40 are respectively installed on two side walls perpendicular to the second direction of the face cover 20 through the first elastic member 25. The pressing portion 41 of each adjustment button 40 is located outside the side wall of the face cover 20, and the tooth engaging portion 42 passes through the side wall of the face cover 20 and inserts into the accommodating cavity, and is engaged with a rack 31 of the telescopic toothed plate 30 under the elastic force of the first elastic member 25 (that is, the block of the tooth engaging portion 42 is embedded into the gap between two adjacent teeth of the rack 31), thereby preventing the telescopic toothed plate 30 from moving in the first direction, as Figure 5 shown. When the two adjustment buttons 40 are respectively pushed in the preset direction (for example, the two adjustment buttons 40 are respectively oriented towards the accommodating cavity), the two adjustment buttons 40 respectively overcome the elastic force of the corresponding first elastic member 25 to release the corresponding rack 31 by the tooth engaging portion 42 (that is, the block of the tooth engaging portion 42 leaves the gap between two adjacent teeth of the rack 31), thereby enabling the telescopic toothed plate portion 30 to move in the first direction in the accommodating cavity, as Figure 6 shown.

[0029] That is, when it is necessary to adjust the wearing length of the watch, only the two adjustment buttons 40 need to be respectively applied with force in the preset direction (the two adjustment buttons 40 need to be applied with force simultaneously), so that the tooth engaging portions 42 of the two adjustment buttons 40 respectively release the two racks 31, as Figure 6 shown. At this time, the telescopic toothed plate 30 can be pushed to move in the first direction. After the telescopic toothed plate 30 moves in place, the two adjustment buttons 40 are released, and the first elastic member 25 immediately pushes the adjustment buttons 40 to make the tooth engaging portion 42 of them re-engage with the rack 31, as Figure 5 shown, so as to keep the wearing length of the watch fixed and complete the adjustment of the wearing length of the watch.

[0030] For the above double-press adjustment watch buckle, by adding the telescopic toothed plate 30 and the two adjustment buttons 40 on the face cover 20, only by operating the two adjustment buttons 40, the telescopic toothed plate 30 can be moved relative to the face cover 20 in the length direction of the watch band 50, so as to realize the adjustment of the wearing length of the watch. Moreover, the above wearing length adjustment process does not require the watch to be removed from the wrist, which greatly facilitates the operation of adjusting the wearing length of the watch.

[0031] Combined with Figure 3 、 Figure 5 、 Figure 6In an embodiment of the present utility model, a second elastic member 23 is disposed in the accommodating cavity of the face cover 20. Two ends of the second elastic member 23 in the first direction respectively abut against the face cover 20 and the telescopic toothed plate 30. That is, when the telescopic toothed plate 30 is in a compressed state, elastic forces in the first direction are respectively applied to the face cover 20 and the telescopic toothed plate 30, and the telescopic toothed plate 30 moves in the direction of withdrawing from the accommodating cavity under the elastic force of the second elastic member 23.

[0032] That is, when the engaging teeth 42 of the two adjusting buttons 40 are respectively disengaged from the two racks 31, the telescopic toothed plate 30 is pushed by the second elastic member 23 to move in the direction of withdrawing from the accommodating cavity, thereby increasing the wearing length of the watch. After the wearing length of the watch is increased to the appropriate position, releasing the two adjusting buttons 40 enables the first elastic member 25 to push the adjusting buttons 40, so that the engaging teeth 42 of the adjusting buttons 40 are re-engaged with the two racks 31 to lock the telescopic toothed plate 30, and the wearing length of the watch is accordingly fixed. This structure can automatically move the telescopic toothed plate 30 outwards when the two adjusting buttons 40 are pressed, thus further facilitating the adjustment of the wearing length of the watch, and at the same time avoiding the telescopic toothed plate 30 being retracted into the face cover 20 and being difficult to take out (for example, when the telescopic toothed plate 30 is not connected to the watch band).

[0033] As Figure 3 shown, in an embodiment of the present utility model, a first slot 223 is disposed in the accommodating cavity of the face cover 20 along the first direction, and the opening of the first slot 223 faces the opening of the accommodating cavity; correspondingly, a second slot 321 is disposed on the telescopic toothed plate 30 along the first direction, and the opening of the second slot 321 faces the opening of the first slot 223. The second elastic member 23 is composed of a first compression spring whose two ends are respectively inserted into the first slot 223 and the second slot 321. The above structure facilitates the assembly of the second elastic member 23 between the face cover 20 and the telescopic toothed plate 30. Of course, in practical applications, the first slot 223 and the second slot 321 can also be replaced by blind holes or similar structures, which will not be elaborated here.

[0034] In an embodiment of the present utility model, the telescopic toothed plate 30 includes a rectangular frame portion. Two side frames of the rectangular frame portion along the first direction are respectively composed of two racks 31. The rectangular frame portion further includes a middle frame 32 disposed between the two racks 31 and along the first direction, and the second slot 321 is located on the middle frame 32. Correspondingly, the first slot 223 is also located on the center line (this center line is along the first direction) of the accommodating cavity, thereby improving the stability of the telescopic toothed plate 30 moving along the first direction.

[0035] As Figure 3As shown, in an embodiment of the present utility model, the face cover 20 includes an upper cover 21 and a bottom box 22. The upper cover 21 includes a top plate 211 and two first side plates 212 that are respectively vertically connected below the top plate 211 and perpendicular to the second direction. The bottom box 22 is fixed between the two first side plates 212, and a receiving cavity is formed between the top plate 211 and the bottom box 22. Through the assembly structure of the upper cover 21 and the bottom box 22, the processing difficulty of the face cover 20 can be reduced and the process can be simplified.

[0036] In an embodiment of the present utility model, the plane where the two racks 31 on the telescopic toothed plate 30 are located is parallel to the top plate 211 of the upper cover 21, and the two racks 31 are arranged oppositely (that is, the teeth on the rack 31 are located inside). The pressing part 41 of the adjustment button 40 is in the shape of a strip arranged along the first direction. Each adjustment button 40 further includes a plug-in arm 43. The plug-in arm 43 is vertically connected to the inner side surface of the pressing part 41, and the tooth engaging part 42 is located at the free end of the plug-in arm 43 and includes a convex tooth facing the pressing part 41. Correspondingly, the two side walls of the face cover 20 perpendicular to the second direction are respectively provided with first through holes 2122 adapted to the cross section of the plug-in arm. The plug-in arm 43 passes through the first through holes 2122 and makes the tooth engaging part 42 extend into the receiving cavity. The above plug-in arm 43 can guide the movement direction of the tooth engaging part 42 to a certain extent.

[0037] Particularly, the tooth engaging part 42 protrudes from the lower surface of the plug-in arm 43. After the plug-in arm passes through the first through hole and crosses over the rack 31 from above the rack 31, the tooth engaging part 42 is embedded into the gap between the rack 31 of the telescopic toothed plate 30 and the middle frame 32.

[0038] In an embodiment of the present utility model, the outer surfaces of the two first side plates 212 of the upper cover 21 have grooves 2121. The pressing part 41 of the adjustment button 40 is embedded in the grooves 2121. The first elastic member 25 is located between the inner side surface of the pressing part 41 and the side wall of the face cover 20. When the pressing part 41 is pressed and the first elastic member 25 is in the maximum compressed state, the tooth engaging part 42 of the adjustment button 40 releases the corresponding rack 31 on the telescopic toothed plate 30; when the adjustment button 40 is not subjected to an external force, the first elastic member 25 pushes the adjustment button 40, so that the outer end surface of the adjustment button 40 protrudes outside the groove 2121, and at the same time, the tooth engaging part 42 of the adjustment button 40 is engaged with the corresponding rack 31 on the telescopic toothed plate 30. The above structure can prevent the adjustment button 40 from protruding too much from the side wall of the face cover 20 and improve the consistency of the entire double-press adjustment watch buckle.

[0039] In an embodiment of the present utility model, the bottom box 22 includes a bottom plate 221 and two second side plates 222 that are respectively vertically connected above the bottom plate 221 and perpendicular to the second direction, and the distance between the two second side plates 222 is adapted to the size of the telescopic tooth plate 30 in the second direction. The bottom box 22 is assembled to the upper cover 21 in such a way that the outer sides of the two second side plates 222 face the inner sides of the two first side plates 212 respectively (that is, the distance between the two second side plates 222 is smaller than the distance between the two first side plates 212), and the accommodating cavity is formed between the top plate 211 of the upper cover 21, the bottom plate 221 of the bottom box 22, and the two second side plates 222. The above structure facilitates the assembly of the upper cover 21 and the bottom box, and is conducive to controlling the shape and size of the accommodating cavity.

[0040] In an embodiment of the present utility model, the two second side plates 222 are respectively provided with a plurality of screw holes 2221 arranged in the second direction. Correspondingly, the bottom wall of the groove 2121 on the first side plate 212 of the upper cover 21 has a second through hole 2123 corresponding to the screw hole 2221. The pressing parts 41 of the two adjusting buttons 40 are respectively provided with a third through hole 411 corresponding to the second through hole 2123. The bottom box 22 is assembled to the upper cover 21 by screws 24 that pass through the third through hole 411, the second through hole 2123 and are threadedly connected in the screw holes 2221. The first elastic member 25 is composed of a second compression spring sleeved on the screw 24. The first through hole 2122 can penetrate through the first side plate 212 and the second side plate 222 (or the second side plate 222 has a corresponding notch). This structure facilitates the fixing of the bottom box 22 and also facilitates the assembly of the first elastic member 25.

[0041] The present utility model also provides a watch, which includes a watch head, two watch straps and the above double-press adjustment buckle. The two ends of one watch strap are respectively connected to the first end of the watch head (such as the 12 o'clock position) and the buckle base of the double-press adjustment buckle, and the two ends of the other watch strap are respectively connected to the second end of the watch head (such as the 6 o'clock position) and the face cover of the double-press adjustment buckle.

[0042] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
