[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] The watch band with magnetic absorption and self-locking provided by the embodiment of the present invention, as Figures 1-6 shown, includes: a first watch band seat 1, a second watch band seat 2, and a self-locking mechanism 3;

[0043] The first watch band seat 1 is magnetically attracted to the second watch band seat 2, and the self-locking mechanism 3 locks the first watch band seat 1 and the second watch band seat 2; the second watch band seat 2 is provided with a locking groove 211;

[0044] The self-locking mechanism 3 includes: an elastic reset key 31 and a locking rod 32; the elastic reset key 31 is arranged on the first watch band seat 1, and the fixed end of the locking rod 32 is connected to the elastic reset key 31;

[0045] When the first watch band seat 1 is magnetically attracted to the second watch band seat 2, the elastic reset key 31 is compressed to generate an elastic restoring force, and the elastic restoring force locks the locking end of the locking rod 32 with the locking groove 211.

[0046] In comparison with the prior art in the above technical solutions, the addition of the self-locking mechanism 3 can lock the first watch band seat 1 and the second watch band seat 2, avoiding the separation between the watch band seats during running, swimming, and some large-amplitude movements; it should be noted that one of the first watch band seat 1 and the second watch band seat 2 is connected to the male band 102 of the watch band, and the other is connected to the mother band 9 of the watch band.

[0047] Optimizing the above technical solutions, as Figures 3-4 shown, the lower surface of the first watch band seat 1 has a magnetic recess 11, the upper surface of the second watch band seat 2 has a magnetic protrusion 21 that engages with the magnetic recess 11, and the locking groove 211 is arranged on the magnetic protrusion 21;

[0048] When the magnetic recessed part 11 is buckled on the magnetic protruding part 21, the elastic reset key 31 is compressed to generate an elastic restoring force, and the elastic restoring force locks the locking end of the locking rod 32 with the locking groove 211.

[0049] In the above technical solution, through the settings of the magnetic recessed part 11 and the magnetic protruding part 21, the first watch band seat 1 and the second watch band seat 2 can be accurately aligned and buckled, improving the accuracy of the watch band buckling magnetic attraction and the wearing speed.

[0050] Further optimize the above technical solution, such as Figure 1 and Figure 2 As shown, the magnetic protruding part 21 is also provided with a magnetic groove 212, and a first magnet 4 is installed in the magnetic groove 212;

[0051] A second magnet 5 is installed at a position corresponding to the magnetic groove 212 of the magnetic recessed part 11.

[0052] In the above technical solution, through the position settings of the first magnet 4 and the second magnet 5, the magnetic attraction of the watch band buckling is made more firm; of course, the first magnet 4 and the second magnet 5 can be replaced to extend the service life of this watch band and avoid the situation that this watch band cannot be used due to the demagnetization of the magnet.

[0053] In this technical solution, as Figure 1 and Figure 2 shown, a key hole 12 penetrating through it is formed on the peripheral wall of the first watch band seat 1, and the elastic reset key 31 is slidably installed in the key hole 12;

[0054] One side of the elastic reset key 31 facing the center of the first watch band seat 1 is connected to the fixed end of the locking rod 32, and the locking end of the locking rod 32 is located in the magnetic recessed part 11.

[0055] In the above technical solution, when the magnetic recessed part 11 is magnetically buckled on the magnetic protruding part 21, the gap between the locking end of the locking rod 32 and the elastic reset key 31 is caught on the side wall corresponding to the locking groove 211 on the second watch band seat 2, so that the elastic reset key 31 is compressed to generate an elastic restoring force, and further the locking end of the locking rod 32 is locked with the locking groove 211.

[0056] Optimize the above technical solution. The locking end of the locking rod 32 is a hook-shaped head, and the shape of the locking groove 211 is a hook-shaped groove matching the hook-shaped head. In this technical solution, when the first watch band seat 1 is buckled and fixed on the second watch band seat 2 by magnetic attraction, the hook-shaped head is hooked and clamped in the hook-shaped groove. With such a setting, the locking between the first watch band seat 1 and the second watch band seat 2 is made more stable.

[0057] Further optimize the above technical solution, such as Figure 2As shown, the locking groove 211 includes: an axially connected axial groove 2111 and a radial groove 2112;

[0058] The axial groove 2111 is arranged along the axial direction of the magnetic protrusion 21, and the radial groove 2112 is arranged along the radial direction of the magnetic protrusion 21;

[0059] When the magnetic recess 11 is buckled on the magnetic protrusion 21, the locking end of the locking rod 32 passes through the axial groove 2111 and is locked in the radial groove 2112.

[0060] In the above technical solution, through the arrangement of the axial groove 2111 and the radial groove 2112, the locking between the first watch band seat 1 and the second watch band seat 2 is more firm; it should be noted that the hook-shaped head of the locking rod 32 is clamped in the radial groove 2112.

[0061] In this technical solution, as Figure 3 shown, a limiting shaft 13 is axially installed on the peripheral wall of the first watch band seat 1, and the elastic reset key 31 is provided with a limiting groove 311 that cooperates with the limiting shaft 13.

[0062] In this technical solution, through the cooperation between the limiting shaft 13 and the limiting groove 311, the position of the elastic reset key 31 can be limited.

[0063] In this technical solution, as Figure 3 shown, the elastic reset key 31 includes: a reset spring 312, and the reset spring is used to provide an elastic restoring force.

[0064] In this technical solution, due to the setting of the reset spring 312, an elastic restoring force can be provided to lock the first watch band seat 1 and the second watch band seat 2, and the reset spring 312 is a finished product, which is beneficial to reducing costs.

[0065] In this technical solution, as Figure 1 and Figure 3 shown, the number of the self-locking mechanisms 3 is two, and the two self-locking mechanisms 3 are symmetrically arranged on the first watch band seat 1;

[0066] The number of the locking grooves 211 is two, and the two locking grooves 211 are symmetrically arranged on the magnetic protrusion 21;

[0067] When the magnetic recess 11 is buckled on the magnetic protrusion 21, one elastic reset key 31 is compressed to generate an elastic restoring force, and the elastic restoring force locks the locking end of the corresponding locking rod 32 with the corresponding locking groove 211; the other elastic reset key 31 is compressed to generate an elastic restoring force, and the elastic restoring force locks the locking end of the corresponding locking rod 32 with the corresponding locking groove 211.

[0068] In the above technical solution, the symmetrically arranged self-locking mechanism 3 makes the self-locking between the first watchband seat 1 and the second watchband seat 2 more firm. In one embodiment, after the first watchband seat 1 and the second watchband seat 2 are locked, a compressive force opposite to the direction of the elastic restoring force is applied to the elastic reset key 31, so that the locking end of the locking rod 32 is disengaged from the locking groove 211, so as to unlock the first watchband seat 1 and the second watchband seat 2.

[0069] In one embodiment, as Figure 2 and Figure 4 shown, the shape of the magnetic recess 11 is rectangular, and the shape of the magnetic protrusion 21 is rectangular and matches the magnetic recess 11. By setting the shapes of both the magnetic recess 11 and the magnetic protrusion 21 to be rectangular, the accuracy of the magnetic attraction for buckling the watchband and the wearing speed are further improved, and the rectangle is easy to process, which is beneficial to cost saving.

[0070] This utility model example also provides a watch, including: a watchband with magnetic attraction and self-locking as described above. Since this solution adopts the above piston engine muffler device, it accordingly has corresponding beneficial effects, which can be specifically referred to the previous description and will not be elaborated here.

All feasible feature combinations are the technical contents clearly recorded in this article. Any one of the sub-features included in the same statement can be independently applied without necessarily being applied together with other sub-features.

[0072] The following further introduces this solution in combination with specific embodiments:
