It is robust and reliable, has fewer structural components, and can effectively reduce costs.

[0052] The assembly method for a watch includes the following steps:

[0053] Step S101: Assemble the toggle box assembly 30. First, install both ear clips 35 onto the base box 314, with the stop block 352 of the ear clip 35 located inside the storage cavity 3141 of the base box 314. The pin 353 of the ear clip 35 passes through the positioning hole 313. Then, install the push-pull member 33 onto the ear clips 35. The two sliders 333 on the push-pull member 33 are slidably connected to the sliding grooves 351 on the two ear clips 35, respectively. After that, the elastic member 34... One end is fitted onto the limiting rod 332 and abuts against the main body 331 on the push-pull member 33. The other end of the elastic member 34 is located between the two limiting plates 3143 and abuts against the inner wall of the storage cavity 3141 in the bottom box 314. Finally, multiple fasteners 316 are passed through the corresponding through holes 3151 in the cover plate 315 and connected to the corresponding threaded holes 3142 on the bottom box 314 to complete the assembly of the toggle box assembly 30. The toggle head 32 is not installed yet.

[0054] Step S102: Install the toggle box assembly 30. The watch strap 10 is formed on the toggle box assembly 30 using a die-cutting process. The toggle box 31 is installed in the receiving space 11 of the watch strap 10, and the pin 353 in the buckle 35 passes through the corresponding perforation 13 of the watch strap 10.

[0055] Step S103: Install the dial head 32. One end of the dial head 32 is located outside the watch strap 10, and the other end of the dial head 32 passes through the limiting hole 12 in the watch strap 10 and the dial hole 312 in the dial box 31 in sequence, and then engages with the slot 334 on the push-pull component 33.

[0056] Step S104: Assemble the watch. Push the dial 32 downwards. During the pushing process, the dial 32 will drive the two lugs 35 to move in opposite directions simultaneously through the push-pull component 33. The elastic component 34 will be compressed, and both lugs 35 will retract inwards to align with the dial 20. Then release the dial 32. Under the elastic recovery of the elastic component 34, the push-pull component 33 will drive the two lugs 35 to move in opposite directions. The two lugs 35 will be stretched outwards and inserted into the corresponding spring bar holes 22. The dial 32 will simultaneously return to its original position upwards. The watch strap 10 can be installed on the dial 20 along with the dial box assembly 30, completing the finished product assembly.

[0057] The steps for disassembling and assembling the watch strap are as follows:

[0058] When the watch strap 10 needs to be removed, push the lever 32 downwards about 1-1.1mm in the direction of the arrow on the lever 32. During the pushing process, the lever 32 will drive the push-pull component 33 to move 1mm. Since the slider 333 on the push-pull component 33 and the slide groove 351 on the lug 35 cooperate with each other, the push-pull component 33 will drive the two lugs 35 to move towards each other at the same time. The elastic component 34 will be compressed, and the two lugs 35 will slide towards the middle at the same time. Both lugs 35 will retract inwards and disengage from the corresponding spring bar holes 22. Then, the watch strap 10 can be removed from the dial 20 along with the lever box assembly 30.

[0059] When the watch strap 10 needs to be assembled, press down on the turntable 32 and keep it still. At this time, the watch strap 10 is in its original position. Release the turntable 32. Under the elastic recovery of the elastic element 34, and with the cooperation of the designed slider 333 and the slide groove 351, the push-pull element 33 drives the two lugs 35 to move in the opposite direction. The two lugs 35 are pushed outward under the action of the elastic element 34 and extend outward. The two lugs 35 automatically reset, and the turntable 32 resets upward at the same time. The two lugs 35 are inserted into the corresponding spring bar holes 22 respectively, and the watch strap 10 can be installed on the dial 20 along with the turntable assembly 30.

[0060] In summary, when the watch strap 10 needs to be removed, the pusher 32 is pushed, and the pusher 32 drives the two lugs 35 to move in opposite directions through the push-pull member 33. The elastic member 34 is compressed, and the two lugs 35 disengage from their respective spring bar holes 22. The watch strap 10 can then be removed from the dial 20 along with the setter assembly 30. When reassembly is required, the pusher 32 is released, and under the action of the elastic member 34, the push-pull member 33 drives the two lugs 35 to move in the opposite direction. The pusher 32 resets, and the two lugs 35 are inserted into their respective spring bar holes 22. The watch strap 10 can then be installed on the dial 20 along with the setter assembly 30. This replaces the spring bar switch, snap-on, and screw installation methods used in traditional watch straps 10. The disassembly and reassembly of the watch strap 10 does not require the use of specific tools. The entire disassembly and reassembly process is simple, convenient, innovative, and reliable. It can be used with existing dials 20 and is suitable for widespread adoption.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
