Referring to fig. 3 and 4, the switch slot 22 includes a sliding slot 221 and a spring latching slot 222 disposed at the bottom of the sliding slot 221, and the switch slot 22 is communicated with the first through hole 21 through a side edge of the spring latching slot 222. In addition, the catching portion 4122 of the switch slider 412 has a catching edge, and when the switch slider 412 and the first spring 411 are assembled to the switch slot 22, the catching edge of the catching portion 4122 passes through the side of the spring catching slot 222 under the action of the first spring 411 and protrudes into the first through hole 21. Of course, after the lock bar 421 sequentially passes through the first through hole 21 at the rear end of the first side bead 2, the second through hole 11 at the front end of the middle bead 1 with the adjacent bead, and the blind hole 31 at the rear end of the second side bead 3, the slot structure 4211 of the lock bar 421 is located in the first through hole 21 and corresponds to the communication position between the first through hole 21 and the spring latching groove 222. At this time, the locking portion 4122 of the switch slider 412 can be efficiently and reliably locked to the locking groove structure 4211 of the lock lever 421, and the lock lever 421 can be stably and reliably fixed in the first through hole 21 by the elastic force of the first spring 411 in the direction of the first through hole 21 acting on the switch slider 412.

The locking edge of the locking portion 4122 of the switch slider 412 is provided with a chamfered surface, and when the switch slider 412 is inserted into the switch slot 22, the chamfered surface of the locking edge faces away from the second side bead 3, that is, the chamfered surface of the locking bar 421 impacts the locking edge when inserted into the first through hole 21, at this time, the chamfered surface can be pushed by the head end of the locking bar 421, so that the switch slider 412 moves in the direction away from the first through hole 21 while compressing the first spring 411, the locking bar 421 can be inserted without manually sliding the switch slider 412, and when the slot structure 4211 of the locking bar 421 moves along with the locking bar 421 to correspond to the communication position between the first through hole 21 and the switch slot 22, the switch slider 412 can be automatically clamped to the slot structure 4211 of the locking bar 421, so that the operation is more convenient and fast, the structural design is more reasonable, and the practicability of the use is improved.

Of course, in practical applications, a chamfered surface may be provided at the head end of the lock rod 421, which facilitates the smooth pushing-open of the switch slider 412 and improves the convenience of assembly.

In order to facilitate efficient and stable buckling of the lock rod 421 with the buckling portion 4122 of the switch slider 412, the buckling groove structure 4211 of the lock rod 421 is configured as an annular groove arranged along the circumferential direction, that is, the lock rod 421 does not need to be recognized in the insertion direction during assembly insertion, and the assembly difficulty and the assembly efficiency can be effectively improved.

As shown in fig. 5, the spring locking device 42 further includes a second spring 422 disposed at the head end of the lock bar 421, and when the fastening portion 4122 of the switch slider 412 is fastened to the fastening groove structure 4211 of the lock bar 421, the head end of the lock bar 421 is inserted into the blind hole 31 of the second lateral bead 3 and presses the second spring 422. That is, when the sliding switch slider 412 releases the fastening portion 4122 from the slot structure 4211 of the lock rod 421, the lock rod 421 can be automatically ejected out of the first through hole 21 under the action of the second spring 422, so that the detachment is more convenient and faster, the detachment difficulty is reduced, and the operation problem that the lock rod 421 cannot be taken out is avoided; moreover, by providing the second spring 422, when the buckling part 4122 of the switch slider 412 buckles the buckling groove structure 4211 of the lock rod 421, the lock rod 421 is subjected to an elastic force along the axial direction thereof and in a direction away from the second side bead 3, so that the movement of the lock rod 421 in the axial direction thereof can be effectively restrained, the lock rod 421 is prevented from moving, and the stability of the buckling mode is further improved.

In order to facilitate the installation and fixation of the second spring 422, the head end of the lock rod 421 has a spring installation groove arranged along the axial direction thereof, and at least a part of the second spring 422 is embedded and fixed in the spring installation groove. Of course, the fixing flange may be provided such that the inner hole of the second spring 422 is sleeved on the fixing flange, thereby fixing the second spring 422, but this will reduce the stability of the fixing of the second spring 422.

In particular, the switch device 41 further includes a limiting pressing ring 413, and the external dimension of the limiting pressing ring 413 matches with the external dimension of the sliding groove 221; therefore, the limiting compression ring 413 can be installed and fixed in the sliding groove 221 without other installation structure designs.

Correspondingly, the buckling edge of the buckling part 4122 protrudes out of the side edge of the sliding part 4121, and when the switch slider 412 and the first spring 411 are assembled in the switch groove 22 and the limiting pressing ring 413 is pressed and embedded in the sliding groove 221, the lower surface of the limiting pressing ring 413 is limited and attached to the upper surface of the buckling edge of the buckling part 4122, that is, the switch slider 412 can be fixed in the switch groove 22 by the limiting pressing ring 413, and when the switch slider 412 moves, the upper surface of the buckling edge of the buckling part 4122 moves on the lower surface of the limiting pressing ring 413, so that the switching function of the switch slider 412 is ensured. Of course, the size of the outer portion of the sliding portion 4121 of the switch slider 412 away from the locking portion 4122 may be larger than the size of the inner portion of the sliding portion 4121 close to the locking portion 4122, and in this case, the stopper ring 413 may be restricted to the outer periphery of the inner portion of the moving portion 4121 close to the locking portion 4122, which is advantageous for the sliding portion 4121 of the switch slider 412 during the detaching operation.

In order to further facilitate the sliding of the sliding portion 4121 of the switch slider 412, the outer side surface of the sliding portion 4121 of the switch slider 412 is provided with anti-sliding embossed patterns, so that the friction force between the switch slider 412 and the sliding portion 4121 during sliding can be increased, and the switch slider 412 can be driven to move against the first spring 411 while the sliding portion 4121 is driven.

In order to further improve the convenience of assembly, a limit groove 4123 for limiting the first spring 411 is arranged on one side of the buckling part 4122 of the switch slider 412, which is back to the buckling edge, and the side edge of the limit groove 4123 penetrates through the bottom surface of the buckling part 4122; therefore, the processing difficulty of parts can be reduced while the assembly is more convenient, so that the weight of the parts can be effectively reduced, and the wearing comfort of the quick-release watchband is improved.

In another embodiment of the present invention, the opening of the switch groove 22 is disposed on the upper surface of the first side bead 2, and the switch groove 22 is perpendicular to the first through hole 21; the outer side surface of the sliding portion 4121 of the switch slider 412 is flush with the upper surface of the first bypass bead 2 or recessed into the upper surface of the first bypass bead 2.

Furthermore, the utility model also provides a wrist-watch, this wrist-watch includes watchband and dial plate, and the watchband of wrist-watch has adopted the quick detach watchband that this embodiment provided.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
