DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Please refer to Figs. 1-2 The utility model provides a kind of tightening mechanism of intelligent bracelet, including two respectively setting in the mounting sleeve 1 of bracelet both sides;

[0022] Driving member 3, rotatable through one side of mounting sleeve 1 and extend to through hole 2;Two sections of watchband end are fixed in two driving members 3 and can slide through corresponding mounting sleeve 1;

[0023] Fixed member 4, threaded through the other side of mounting sleeve 1 and extend to through hole 2;

[0024] The driving member 3 is used to wind or unwind the watchband, so as to control the tension state of the watchband, and the fixing member 4 is used to fix the driving member 3.

[0025] Specifically, referring to Fig. 2 , the driving member 3 comprises a rotating shaft 31 penetrating through one side of the mounting sleeve 1 and rotatably arranged in the through hole 2; a winding shaft 32 arranged at one end of the rotating shaft 31 and located in the through hole 2, used to wind or unwind the watchband; and a first dial 33 arranged at the other end of the rotating shaft 31.

[0026] In this embodiment, the user rotates the first dial 33 to drive the rotating shaft 31 to rotate, and the winding shaft 32 winds or unwinds the watchband accordingly, so as to accurately control the tension of the watchband. Compared with the buckle adjustment mode, the adjustment range is wide and the precision is high, and the tightening degree of the watchband can reach the best. At the same time, compared with the magic tape fixing mode, the fixing is more stable.

[0027] Specifically, referring to Fig. 2 , the fixing member 4 comprises a fixing screw 41 penetrating through the other side of the mounting sleeve 1 and threadedly connected to the through hole 2; a stop plate 42 rotatably arranged at one end of the fixing screw 41 and located in the through hole 2; and a second dial 43 arranged at the other end of the fixing screw 41.

[0028] In this embodiment, when the second dial 43 is rotated, the fixing screw 41 rotates and pushes the stop plate 42 to move, so as to finally abut against the winding shaft 32 and prevent it from rotating randomly, thereby ensuring the stability of the fixed state of the watchband. Compared with the existing buckle and magic tape fixing, the threaded connection fixing mode provides more reliable locking effect.

[0029] Specifically, referring to Fig. 2 , the winding shaft 32 is provided with a fixing disc 5 at the end away from the rotating shaft 31.

[0030] In this embodiment, the fixing disc 5 is used to increase the contact area between the winding shaft 32 and the stop plate 42, so as to improve the fixing effect. Moreover, since the fixing disc 5 supports the other end of the winding shaft 32, the stability of the winding shaft 32 during use can be improved.

[0031] Specifically, referring to Fig. 2 , the fixing disc 5 is provided with a rubber sheet 6 on the opposite side of the stop plate 42.

[0032] In this embodiment, the rubber sheet 6 is used to increase the friction between the fixing disc 5 and the stop plate 42, so as to improve the fixing effect when abutting, and at the same time, avoid the abrasion caused by the direct contact of metal components.

[0033] Specifically, referring to Fig. 2 , a limiting rod 7 is arranged inside the through hole 2 and can slide through the stop plate 42.

[0034] In the embodiment, when the fixed screw 41 pushes the abutting plate 42, the limiting rod 7 limits the rotation of the abutting plate 42, ensures that the abutting plate 42 only moves in the axial direction, and improves the stability of the fixing process.

[0035] Specifically, referring to Fig. 2 The fixed disc 5 and the rotating shaft 31 are both rotatably connected with the inner wall of the through hole 2 through the sealing bearing 8; and the second dial wheel 43 is provided with a sealing ring 9 close to the outer wall of the mounting sleeve 1.

[0036] In the embodiment, the sealing bearing 8 can reduce the rotating friction and prevent dust and water vapor from entering; and the sealing ring 9 can further improve the waterproof and dustproof performance after abutting against the outer wall of the mounting sleeve 1, thereby prolonging the service life of the mechanism.

[0037] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
