Description

Technical Field

[0001] The utility model relates to the technical field of mechanical watches, in particular to a mechanical watch with a quickly replaceable watch strap. Background Art

[0002] Mechanical watches can generally be divided into the following two types: manual-winding and automatic-winding watches. Both of these mechanical watches are powered by the mainspring in the movement, which drives the gears and then pushes the hands. The only difference is the way the power is generated. Manual-winding mechanical watches rely on manually twisting the mainspring for power. The thickness of the movement is thinner than that of an automatic-winding watch, so the weight of the watch is relatively light. Automatic-winding watches use the left and right swing of the automatic rotating disk of the movement to generate power to drive the mainspring, but relatively speaking, the thickness of manual-winding watches is smaller than that of automatic-winding watches.

[0003] After searching, the existing Chinese patent publication number is: CN218978208U, which provides a mechanical watch with a quickly replaceable strap. The patent drives two guide plates to slide in opposite directions along the engaging groove through a threaded rod, thereby pushing the engaging rod out of the inside of the engaging groove. The strap can then be removed from the connecting seat to complete the disassembly of the strap. The operation is simple and fast. When replacing and installing the strap body under the action of the engaging mechanism, it is only necessary to move the two engaging rods and push them into the inner side of the connecting seat to complete the installation, which facilitates the quick replacement of the strap, reduces unnecessary tedious steps, and increases the practicality of the device.

[0035] The following will refer to the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0037] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The utility model provides a mechanical watch with a quickly replaceable strap, comprising a chassis 4 and a plurality of second connecting blocks 6. The outer wall of the protective shell 1 is fixedly connected with evenly distributed fixing blocks 8. Both sides of the inner wall of the first connecting block 3 are penetrated and slidably connected with first connecting columns 10. First springs 11 are provided in the middle of both sides of the inner wall of the first connecting block 3. Both sides of the inner wall of the second connecting column 14 are penetrated and slidably connected with limiting columns 12. One side of the limiting column 12 is fixedly connected with a second spring 13. A protective mirror 2 is provided between the protective shell 1 and the connecting watch ring 7. An adjustment knob 5 is provided on the front side of the chassis 4.

[0038] The protective shell 1 can be rotated more easily through the fixing block 8, the limiting column 12 can be pushed out through the first connecting column 10, the second connecting column 14 can be fixed to the first connecting block 3 through the limiting column 12, the protective mirror 2 is fixedly installed through the protective shell 1 and the connecting watch ring 7, and the time of the mechanical watch is adjusted by adjusting the knob 5.

[0039] Reference Figure 2 、 Figure 4 、 Figure 6 and Figure 7 The rear side of the inner wall of the chassis 4 is penetrated and slidably connected with a slider 9, and the front bottom of the slider 9 is fixedly connected to a uniformly distributed third spring 19. Both ends of the outer wall of the chassis 4 are fixedly connected with a first connecting block 3. The middle of the inner wall of the chassis 4 is penetrated and rotatably connected with a connecting ring 7. The top of the connecting ring 7 is provided with a protective shell 1. The top of the inner wall of the protective shell 1 is fixedly connected with a uniformly distributed third connecting block 15. The inner wall of the connecting ring 7 is penetrated and slidably connected with a uniformly distributed limit block 21. One side of the limit block 21 is fixedly connected to a fourth spring 20.

[0040] The third connecting block 15 can be locked in by the two limit blocks 21 to fix the protective case 1. The slider 9 can prevent the connecting watch ring 7 from rotating, so that the third connecting block 15 can be rotated out. The protective case 1 is opened to quickly replace the protective lens 2, so that the watch always maintains a good appearance and avoids affecting the overall beauty of the watch due to damage to the protective lens 2.

[0041] Reference Figure 5 , one end of the second connecting block 6 at one end passes through and is rotatably connected to the second connecting column 14, both ends of the inner wall of the second connecting block 6 pass through and are rotatably connected to the third connecting column 18, the bolt 17 passes through and is threadedly connected to the front side of the third connecting column 18, and the connecting plate 16 passes through and is rotatably connected between the two third connecting columns 18;

[0042] The two second connecting blocks 6 are connected by the third connecting column 18 and the connecting plate 16, and the position of the connecting plate 16 is limited by the bolt 17 and the third connecting column 18. Therefore, the second connecting block 6 can be replaced by opening the bolt 17, without replacing the entire watch strap, reducing the user's economic loss.

[0043] Working principle: When in use, the protective case 1 is placed on the connecting watch ring 7, and the connecting watch ring 7 is supported by pressing the slider 9 to prevent the connecting watch ring 7 from rotating. The third connecting block 15 is clamped between the two limit blocks 21 by rotating the protective case 1, thereby fixing the visor 2. The protective case 1 is rotated by pressing the slider 9 to make the third connecting block 15 rotate out of the limit block 21, thereby removing the protective case 1 and replacing the visor 2. Quick replacement can allow the watch to always maintain a good appearance and avoid affecting the overall beauty of the watch due to damage to the visor 2. The third connecting column 18 is inserted into the second connecting block 6, and the two connecting plates 16 are installed at both ends of the two third connecting columns 18. By rotating the bolt 17, the position of the connecting plate 16 is limited, and the two second connecting blocks 6 are connected by the connecting plate 16, thereby stacking them into a watch strap. By rotating the bolt 17, the bolt 17 is disengaged from the third connecting column 18, and the connecting plate 16 and the third connecting column 18 are taken out, so that the damaged single second connecting block 6 can be replaced, which can not only reduce the user's economic loss, but also extend the service life of the mechanical watch.
