[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0031] The strap buckle provided in the embodiment of the present application can be applied to wearable devices with straps such as watches and bracelets. In specific applications, after the wearable device is worn on the wrist through the strap, the wearable device can be firmly worn on the wrist by locking the strap buckle; after the locking state of the strap buckle is released, the wearable device can be taken off the wrist.
[0032] The present invention provides the following preferred embodiments
[0033] like Figure 1 , Figure 2 , Fig. 9 and Fig.11As shown, a watch strap buckle includes a cover plate 1, a first fastener 2 rotatably connected to the cover plate 1 at one end, and a second fastener 3 rotatably connected to the other end of the first fastener 2. When the watch strap buckle is applied to a watch, one end of the second fastener 3 is connected to the watch bracelet, and the other end of the second fastener 3 is connected to the first fastener 2; one end of the cover plate 1 is connected to the other end of the first fastener 2, and the other end of the cover plate 1 is connected to the watch bracelet.
[0034] Among them, Figure 4 and Fig.10 The cover plate 1 is provided with a receiving groove 10 for accommodating the first fastener 2, the first fastener 2 is provided with a receiving cavity 20 for accommodating the second fastener 3, the cover plate 1 is symmetrically provided with a slide groove 11 communicating with the receiving groove 10, the two slide grooves 11 are provided with a slide fastener 4 which can move relative to each other when pressed, the second fastener 3 is provided with a buckle platform 30 adapted to the slide fastener 4, the buckle platform 30 is provided with slots 31 on opposite sides, and the slide fastener 4 is provided with an insert block 40 which can be inserted into the slot 31, when the two slide fasteners 4 are pressed to make relative movement, the insert block 40 falls off the slot 31, The first fastener 2 and the second fastener 3 can be separated from the receiving groove 10 and the receiving cavity 20. That is, after the first fastener 2 is received in the receiving groove 10 and the second fastener 3 is received in the receiving cavity 20, the cover plate 1 or the second fastener 3 is slightly pressed to insert the insert block 40 into the slot 31, so that the second fastener 3 presses the first fastener 2, and then the first fastener 2 and the second fastener 3 are locked in the receiving groove 10 of the cover plate 1; the two sliding fasteners 4 are respectively provided with the insert blocks 40 corresponding to the slot 31 and can be inserted into the slot 31, that is, as Figure 3 As shown, since the two sliding fasteners 4 are relatively movable, the plug block 40 on one of the sliding fasteners 4 is in front of the plug block 40 on the other sliding fastener 4, and the other is in the rear. Therefore, the corresponding slot 31 is provided on the side wall of the buckle platform 30 in the opposite direction of the forward direction of the plug block 40. The two sliding fasteners 4 are in a "mutual" shape when connected. Therefore, when the two sliding fasteners 4 are pressed, the plug blocks 40 on the sliding fasteners 4 move away from each other, and the plug blocks 40 on the two sliding fasteners 4 gradually move away, that is, the plug blocks 40 are separated from the slot 31. When the pressure is released, the two sliding fasteners 4 automatically reset, that is, the plug blocks 40 on the two sliding fasteners 4 gradually approach each other, and the plug blocks 40 are inserted into the slot 31.
[0035] In order to enable the two sliding fasteners 4 to reciprocate in one direction in the sliding groove 11 and prevent the two sliding fasteners 4 from being separated from the sliding groove 11, a blocking and resetting structure is provided on the sliding fastener 4, which can limit and reset the sliding fastener 4 when sliding back and forth in the sliding groove 11. The blocking and resetting structure includes a guide limiting groove 12 provided at the bottom of the cover plate 1 and connected to the sliding groove 11. A guide column 41 that can slide in the guide limiting groove 12 is installed on the sliding fastener 4. The guide column 41 can move left and right in the guide limiting groove 12. At the same time, the cooperation between the guide column 41 and the guide limiting groove 12 can prevent the sliding fastener 4 from being separated from the sliding groove 11. In order to enable the sliding fastener 4 to automatically reset without pressure, the sliding fastener 4 is provided with a blocking and resetting structure. 4 is symmetrically provided with two springs 42, and one end of the spring 42 is in contact with the relative wall of the slide groove 11. In the absence of pressure, the spring 42 is always in a stretched state, so that the slider 4 is kept in the buckled state, that is, the insert block 40 is in the slot 31; when the slider 4 is pressed, the guide column 41 moves along the front side of the guide limit slot 12, the spring 42 contracts under pressure, the insert block 40 is disengaged from the slot 31, and the watch band buckle is in an unlocked state; when the pressure pressing the slider 4 is released, the spring 42 automatically stretches and opens, the spring 42 pushes the slider 4, the guide column 41 moves along the rear side of the guide limit slot 12, the insert block 40 is inserted into the slot 31, and the watch band buckle is in a locked state.
[0036] In an optional embodiment, if Figure 5 The first buckle 2 includes a first arc-shaped connector 21 and a second arc-shaped connector 22 spaced apart from the first arc-shaped connector 21. The first buckle 2 is arranged in an arc shape, which can better fit the wrist and improve the comfort when wearing. Two intermediate stops 23 connected to the first arc-shaped connector 21 and the second arc-shaped connector 22 are spaced apart between the first arc-shaped connector 21 and the second arc-shaped connector 22. The first arc-shaped connector 21, the second arc-shaped connector 22 and the intermediate stops 23 are integrated. The first arc-shaped connector 21, the second arc-shaped connector 22 and the intermediate stops 23 form a receiving cavity 20. The thickness of the intermediate stops 23 is less than the height of the receiving cavity 20. Through this design, when the second buckle 3 is accommodated, the bottom end surface of the second buckle 3 is flush with the bottom end surfaces of the first arc-shaped connector 21 and the second arc-shaped connector 22, which improves the comfort of wearing. At the same time, the buckle platform 30 can pass through the first buckle 2 and be buckled with the two sliding buckles 4.
[0037] In order to facilitate the rotational connection with the cover plate 1 and the second fastener 3, both ends of the first arc-shaped connecting member 21 and the second arc-shaped connecting member 22 are provided with first axis connecting holes 24 whose center lines coincide with each other, and the first axis connecting holes 24 at both ends are respectively provided with rotational connecting shafts 25 rotatably connected to the cover plate 1 and the second fastener 3; the rotational connecting shaft 25 connected to the cover plate 1 includes a first rotating shaft and a second rotating shaft, the first rotating shaft is connected to the first arc-shaped connecting member 21, and the second rotating shaft is connected to the second arc-shaped connecting member 22, and the cover plate 1 is provided with rotation holes 13 rotatably connected to the first rotating shaft and the second rotating shaft respectively, and the rotational connecting shaft 25 connected to the cover plate 1 is arranged to be divided into two sections, so as to facilitate the second fastener 3 to be accommodated in the accommodating cavity 20, reduce the setting of the air avoidance groove for the second fastener 3, and reduce the processing process flow.
[0038] Furthermore, in order to facilitate the sliding insertion of the sliding fastener 4 and the second fastener 3 accommodated in the accommodating cavity 20 and to facilitate the sliding of the sliding fastener 4 on the first fastener 2 accommodated in the accommodating groove 10, the top ends of the first arc-shaped connecting member 21 and the second arc-shaped connecting member 22 are provided with a first movable groove 26 that cooperates with the two sliding fasteners 4 to slide, and the outer wall of the first movable groove 26 is provided with a avoidance groove 27 that is recessed toward the accommodating cavity 20. When the sliding fastener 4 is pressed, the sliding fastener 4 moves toward the avoidance groove 27. By providing the avoidance groove 27 and the first movable groove 26, a space for the sliding fastener 4 to slide can be provided in a compact space, thereby improving the rationality of the layout of the watch strap buckle.
[0039] In an optional embodiment, if Figure 6 The second buckle 3 includes a strap connector 32 and an arc-shaped extension 33 connected to the strap connector 32 in a vertical state. The strap connector 32 and the arc-shaped extension 33 are integrated. The strap connector 32 is used to connect the strap, and the arc-shaped extension 33 is connected to the first arc-shaped connector 21 and the second arc-shaped connector 22. The arc-shaped extension 33 is provided with a receiving groove 34 for accommodating the intermediate block 23. The height of the receiving groove is consistent with the thickness of the intermediate block 23. The arc-shaped extension 33 is also provided with a second movable groove 35 corresponding to the first movable groove 26, and the buckle platform 30 is arranged in the second movable groove 35; the strap connector 32 is provided with a connecting through hole 320, and the arc-shaped extension 33 at one end away from the strap connector 32 is provided with a second shaft connecting hole 330 corresponding to the first shaft connecting hole 24, and the rotating connecting shaft 25 is penetrated through the first shaft connecting hole 24 and the second shaft connecting hole 330.
[0040] like Figure 7The slide fastener 4 is engaged with the buckle platform 30 in a sliding and inserting manner. In order to achieve the sliding and inserting effect, the slide fastener 4 comprises a pressing member 43 and a first sliding member 44 connected to the pressing member 43 and slidable in the slide groove 11. The insert block 40 is arranged on the first sliding member 44 away from one end of the pressing member 43. The insert block 40 is in a vertical state with the first sliding member 44. The pressing member 43, the first sliding member 44 and the insert block 40 are integrated. The first sliding member 44 is symmetrically provided with a positioning hole 440 for accommodating the spring 42. The spring 42 is partially exposed outside the positioning hole 440. Both sides of the end of the slide groove 11 are provided with convex portions that contact the exposed part of the spring 42. The guide column 41 is connected to the first sliding member 44. The first sliding member 44 is provided with a threaded hole. The surface of one end of the guide column 41 is provided with an external thread that matches the threaded hole. The guide column 41 is connected to the first sliding member 44 in a threaded manner for easy disassembly.
[0041] Furthermore, if Figure 7 and Figure 8 As shown, in the present embodiment, the first sliding member 44 includes a sliding portion 441 connected to the pressing member 43, and a avoiding portion 442 connected to the sliding portion 441. The sliding portion 441 has shoulders on both sides, and positioning holes 440 are arranged on the two shoulders. The avoiding portion 442 is provided with a avoiding opening 443 along the width direction. The insert block 40 is located at the end of the sliding portion 441, is in a vertical state with the sliding portion 441, and is directly opposite to the avoiding opening 443. The thickness of the insert block 40 is less than that of the sliding portion 441, so that the two sliding buckles 4 are in a "mutual" shape when connected. When the watch strap buckle is locked, the buckle platform 30 is located in the avoiding opening 443.
[0042] In this embodiment, the sliding fastener 4 is buckled with the buckle platform 30 in the form of a sliding groove 11. In order to prevent the end of the sliding fastener 4 from tilting during the movement and prevent the plug block 40 from avoiding the slot 31 and failing to buckle, the two sliding fasteners 4 on one side of the plug block 40 are provided with an anti-slip tilting structure that slides with the sliding fasteners 4 opposite thereto. The anti-slip tilting structure is used to prevent the end of the sliding fastener 4 from tilting when the sliding fastener 4 is pushed. The anti-slip tilting structure includes a stopper 45 provided at the end of the first sliding member 44, a second sliding member 46 connected to the stopper 45, and a guide port 47 provided on the bottom surface of the first sliding member 44 and adapted to the second sliding member 46. The first sliding member 44, the stopper 45, and the guide port 47 provided on the bottom surface of the first sliding member 44 are adapted to the second sliding member 46. The block 45 and the second sliding member 46 are integrated, that is, a guide opening 47 is provided at the bottom of each first sliding member 44, and one of the second sliding members 46 slides in the guide opening 47 on the first sliding member 44 on the opposite side. It should be noted that the end portion of the second sliding member 46 is always located in the guide opening 47, so that no matter what state the slider 4 is in, when the slider 4 is pushed, the end of the slider 4 will not be lifted up, and when the pressing member 43 is pressed to push the first sliding member 44, the second sliding member 46 slides along the guide opening 47 of the opposite first sliding member 44, the stopper 45 contacts the end face of the opposite first sliding member 44, and the plug-in block 40 disengages from the slot 31.
[0043] In an optional embodiment, in order to avoid serious wear and collision between the side walls of the second sliding member 46 and the guide opening 47, a semicircular notch 460 is formed between the end of the second sliding member 46 and the stop block 45, and the corresponding side of the guide opening 47 is provided with a semicircular protrusion 470 that matches the semicircular notch 460. By providing the semicircular notch 460 and the semicircular protrusion 470, collision and friction between the two can be reduced when they slide, thereby ensuring the service life of the anti-slip lifting structure and reducing maintenance.
[0044] In summary, the present application provides an insert block 40 on the slider 4, and provides a buckle platform 30 that is adapted to the slider 4, and provides slots 31 that cooperate with the insert block 40 on opposite sides of the buckle platform 30. When the first buckle 2 is received in the accommodating groove 10 and the second buckle 3 is received in the accommodating cavity 20, under the action of the blocking and resetting structure, the insert block 40 on the slider 4 is pushed into the slot 31, and the watch band buckle is in a locked state; when the two sliders 4 are pressed, When making relative movement, the insert block 40 falls off the slot 31, the watchband buckle is in an unlocked state, and the first buckle 2 and the second buckle 3 can be separated from the accommodating groove 10 and the accommodating cavity 20; in order to prevent the slider 4 from tilting when pushing the slider 4, an anti-slip tilting structure is provided on the slider 4 that slides relatively with it, so that the end of the slider 4 is prevented from tilting when pushing the slider 4, so that the insert block 40 and the slot 31 are always kept on the same horizontal plane, ensuring that the insert block 40 and the slot 31 are buckled. The present invention adopts a sliding insertion method instead of a buckle method, which is reliable and easy to open.
