[0038] In this embodiment, the tension fine-tuning device is used to connect the first belt body 1 and the second belt body 9. The first belt body 1 is provided with a plurality of limiting portions 1-1, and the limiting portions 1-1 are preferably limiting holes, and the distances between adjacent limiting holes are the same;
[0039] The tension fine-tuning device comprises:
[0040] The housing is connected to the second belt body 9. Specifically, the outer end of the second belt body 9 is connected to the housing, and can be connected by a pin shaft 8;
[0041] A sliding component 4, which can be selectively engaged with the limiting portion 1-1; a portion of the sliding component 4 is inside the housing, and a portion thereof extends out of the housing, and is used to be connected to the first belt body 1;
[0042] A sliding limiter 3, the sliding limiter 3 is slidably connected to the sliding component 4, the sliding limiter 3 is used to limit the sliding direction of the sliding component 4, and the sliding limiter 3 and the sliding component 4 are both installed in the housing, and the top of the sliding component 4 extends out of the housing so as to be connected to the limiting portion 1-1, thereby realizing the connection between the second belt body 9 and the first belt body 1;
[0043] The gear slider 5 is provided with a plurality of gear parts 5-1, and the distance between each gear part 5-1 is smaller than the distance between adjacent limiting parts 1-1. The above arrangement can realize the limiting of the position between two adjacent limiting parts 1-1, and the sliding component 4 can be moved to correspond to the position of each gear part 5-1 respectively, so as to facilitate the limiting of each gear part 5-1, and the gear slider 5 can be moved to lock or unlock the gear part 5-1 with the sliding component 4; further, the length of the gear slider 5 along the extension direction of the second belt body 9 is preferably smaller than the distance between two adjacent limiting parts 1-1, that is, the tension fine-tuning device is mainly used to adjust the position between two adjacent limiting parts 1-1.
[0044] The tension fine-tuning device provided by the present invention cooperates with the sliding component 4 and the sliding limiter 3. Since the distance between the gear portions 5-1 is smaller than the distance between the adjacent limit portions 1-1, the gear portions 5-1 can be used to achieve fine-tuning and limiting of the sliding component 4 without affecting the cooperation between the sliding component 4 and the upper limit portion 1-1 of the first belt body 1. The device can effectively increase the adjustable range of the connection length between the first belt body 1 and the second belt body 9, improve wearing comfort, and is easy to operate, simple to manufacture, and low in cost.
[0045] Specifically, the tightness fine-adjustment device can be used to adjust the tightness of the straps of wearable devices such as watches, bracelets, VR, AR, etc.
[0046] In some embodiments, a gripping portion is further provided on the gear sliding member 5. The gripping portion 5-2 can be located on the side of the gear sliding member 5 away from the gear portion 5-1. The force direction of the gripping portion 5-2 is perpendicular to the arrangement direction of the gear portions 5-1, which facilitates pulling or pressing the gear sliding member 5 to achieve the connection or separation of the gear sliding member 5 and the sliding component 4.
[0047] In some embodiments, the gripping portion 5-2 is a gripping boss, and a sliding hole 7-1 is provided on the shell for the gripping boss to extend out. The gripping boss extends out through the sliding hole 7-1. When the device needs to be adjusted, the user can pull or push the gripping boss by hand, which is easy to operate.
[0048] In some embodiments, the housing includes a first housing 2 and a second housing 7, the first housing 2 and the sliding stopper 3 are both fixed in the second housing 7, and the sliding component 4 can extend to the outside of the housing after passing through the space between the first housing 2 and the sliding stopper 3, and the sliding hole 7-1 is provided in the second housing 7. Specifically, the first housing 2 and the sliding stopper 3 can be arranged in a staggered manner, that is, the sliding stopper 3 is installed inside the second housing 7, and the first housing 2 can be a cover plate installed on the surface of the second housing 7; the above arrangement is convenient for assembly and reliable in use by splitting the housing into the first housing 2 and the second housing 7, after the sliding stopper 3 is fixed in the second housing 7, installing the sliding component 4, and then fixing the first housing 2 on the second housing 7. Specifically, the first housing 2 and the sliding stopper 3 can be welded on the second housing 7 to ensure the firmness of the connection; the sliding component 4 is directly inserted into the sliding groove 3-1 of the sliding stopper 3, and the sliding stopper 3 constrains the movement direction of the sliding component 4.
[0049] In some embodiments, an elastic member 6 is provided between the gear sliding member 5 and the housing. The elastic member 6 can press the gear sliding member 5 against the sliding member 4. Specifically, the elastic member 6 can be a spring, which is installed on the side of the gear sliding member 5 where the holding portion 5-2 is provided. The number of elastic members 6 is preferably two, which are respectively located on the left and right sides of the holding portion 5-2. The elastic member 6 is in a pre-compressed state, and the elastic member 6 can effectively prevent the gear sliding member 5 from sliding towards the direction of the sliding hole 7-1, which may cause the sliding member 4 to become disengaged from the gear portion 5-1, thereby improving the reliability of use.
[0050] In some embodiments, as Figure 4 shown, a sliding groove 3-1 is formed on the sliding limiting member 3. The sliding member 4 includes a sliding rod and a slider. The slider cooperates with the sliding groove 3-1 and can slide along the sliding groove 3-1. The sliding rod can extend out of the housing and be engaged with the limiting portion 1-1; the sliding rod can be inserted into the limiting hole of the first belt body 1, thereby realizing the position locking of the sliding rod and the first belt body 1. The device mainly realizes the position change of the first belt body 1 relative to the second belt body 9 by changing the position of the sliding rod relative to the housing.
[0051] In some embodiments, the gear portion 5-1 is a gear groove, and the distances between adjacent gear portions 5-1 are the same. The gear groove can be locked or unlocked in the arrangement direction of the sliding rod in the gear portion 5-1. Specifically, the number of gear portions 5-1 is N, and the distance between adjacent limiting portions 1-1 is L. Then, the distance between adjacent gear portions 5-1 is preferably L / N.
[0052] In some embodiments, a limiting step is provided at the top of the sliding rod. The limiting step can be engaged with the limiting portion 1-1, and the limiting step can ensure the connection strength between the sliding rod and the limiting hole and ensure the connection reliability.
[0053] In some embodiments, the housing, the sliding limiting member 3, and the gear sliding member 5 all extend in an arc shape. The sliding member 4 can slide along the extending direction of the sliding limiting member 3; the gear sliding member 5 can slide towards or away from the sliding limiting member 3, and the positions of the gear sliding member 5 and the sliding limiting member 3 in the sliding direction of the sliding member 4 remain unchanged.
[0054] In a specific embodiment, as Figure 1 shown, the tension fine-tuning device includes a gear sliding member 5, a sliding limiting member 3, a sliding member 4, an elastic member 6, a first housing 2, a second housing 7, a pin shaft 8, a first belt body 1, and a second belt body 9; the first belt body 1 is provided with limiting holes with the same spacing; as Figure 2 shown, the gear sliding member 5 is composed of five gears, which are respectively composed of five gear grooves. The distances between the gear grooves are equal, and each is one-fifth of the spacing between two limiting holes; the second belt body 9 is installed on the side of the second housing 7 through the pin shaft 8; the first belt body 1 is buckled on the second housing 7 through the sliding member 4, asFigure 3 As shown; a sliding hole 7-1 is opened on one side of the second shell 7, and the gear sliding member 5 is installed between the second shell 7 and the first shell 2 through the sliding hole 7-1; the elastic component 6 is installed between the gear sliding member 5 and the second shell 7 through the positioning column; by toggling the sliding member 4 to make it move in the sliding limit member 3, the length of the strap is controlled.
[0055] The working principle of this device before the first belt body 1 and the second belt body 9 are buckled is: by pulling the gear sliding member 5, the gear sliding member 5 moves in the housing along the compression direction of the elastic member 6; when the gear sliding member 5 is completely separated from the sliding member 4, as shown in FIG. Figure 5 , the sliding component 4 is moved along the sliding stopper 3, and when the sliding component 4 moves to the rightmost gear slot, the belt length is the longest within the adjustment range, such as Figure 6 When the sliding member 4 moves to the middle gear slot, the belt length is moderate within the adjustment range, such as Figure 7 When the sliding component 4 moves to the leftmost gear slot, the belt length is the shortest within the adjustment range. Figure 8 When the sliding component 4 moves to the gear position with appropriate tightness of the strap, the gear sliding component 5 is pushed to move in the direction of stretching of the elastic component 6 until the gear sliding component 5 and the sliding component 4 are completely locked, the second strap 9 and the first strap 1 are buckled, and the tightness adjustment of the strap is completed.
[0056] The working principle of this device after the first belt body 1 and the second belt body 9 are buckled together: the first belt body 1 and the second belt body 9 are buckled together, and the gear slider 5 is pulled to make the gear slider 5 move in the shell along the compression direction of the elastic component 6; when the gear slider 5 moves to be completely separated from the sliding component 4, the entire device is moved along the extension direction of the first belt body 1, and when the entire device moves to a gear position with appropriate tightness, the gear slider 5 is pushed to move in the stretching direction of the elastic component 6 until the gear slider 5 and the sliding component 4 are completely locked, and the tightness adjustment of the belt body is completed.
[0057] The tightness fine-tuning device can meet the wearing comfort of wearable devices such as watches and bracelets by fine-tuning the length of the belt body within a certain adjustment limit.
