[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0026] Example

[0027] like Figure 1-5 As shown;

[0028] The rubber watch strap comprises a watch strap 1, a watch strap 2 and a frame 3, wherein the watch strap 1 and the watch strap 2 are connected with the frame 3, wherein the watch strap 1, the watch strap 2 and the frame 3 are all made of soft rubber material, a hard block 4 is provided at one end of the watch strap 2, the hard block 4 can be made of harder rubber material, and the watch strap 2 is connected to the frame 3 through the hard block 4; an adjustment mechanism 5 is installed on the hard block 4, and the adjustment mechanism 5 comprises a knob 51, and an active groove 41 is opened in the hard block 4, and the knob 51 is arranged at one end of the active groove 41 A gear 1 52 is provided, a knob 51 is located on the surface of the hard block 4, a gear 2 53 is also provided in the movable groove 41, the gear 1 52 and the gear 2 53 are connected in transmission, and can be driven by an auxiliary gear or a transmission belt, so that the gear 1 52 and the gear 2 53 rotate in opposite directions, and telescopic grooves 42 are symmetrically opened in the hard block 4, and the two ends of the frame 3 extend into the corresponding telescopic grooves 42 respectively, and racks 31 are provided on one side of both ends of the frame 3, and the two racks 31 are respectively meshed with the gear 1 52 and the gear 2 53;

[0029] When in use, the knob 51 is rotated to rotate the gear 1 52 and the gear 2 53, and the two ends of the frame 3 are moved outward in coordination with the meshing of the rack 31, so that the size of the frame 3 becomes larger, and then the dial is first placed in the frame 3, and then the knob 51 is rotated in the opposite direction to move the two ends of the frame 3 into the telescopic groove 42, so that the size of the frame 3 gradually becomes smaller, until the dial is completely covered inside it, and the frame 3 is stuck in the groove outside the dial, so that the dial is installed. In this way, it can be applied to dials of different shapes and sizes, and it is highly practical.

[0030] Furthermore, a positioning rod 54 is installed through the knob 51, and a circle of positioning grooves 43 are provided on the surface of the hard block 4 around the knob 51. The positioning rod 54 can be inserted into the positioning groove 43. The knob 51 is fixed by inserting the positioning rod 54 into the positioning groove 43, so that the gear 1 52 and the gear 2 53 are locked. After the installation of the dial is completed, the size of the frame 3 is fixed, ensuring the fixing effect of the dial after installation, and effectively preventing the dial from falling off the frame 3;

[0031] Furthermore, a limit frame 6 is symmetrically provided on the hard block 4, and the two ends of the frame 3 pass through the corresponding limit frames 6 respectively. The limit frames 6 limit the two ends of the frame 3. On the one hand, it ensures that the two ends of the frame 3 can move smoothly in the telescopic groove 42. On the other hand, it can prevent the frame 3 from being offset in the longitudinal direction, thereby causing it to not be completely covered outside the dial, so that the dial is at risk of detaching from the frame 3 when in use.

[0032] like Figure 5 As shown;

[0033] The back of the strap 1 and the strap 2 are evenly provided with ventilation grooves 7. After the user wears them, the back of the strap 1 and the strap 2 are in contact with the user's wrist, and a plurality of ventilation holes are formed on the contact surface through the ventilation grooves 7, thereby effectively preventing the user's wrist from sweating after long-term wearing, which causes discomfort.

[0034] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
