[0029] Please see Figures 1 to 11The present invention provides a technical solution: a watch strap connection structure, including a watch case 1, characterized in that: a watch strap 2 that is easy to assemble and disassemble is connected to the side of the watch case 1, a set of connecting lugs 3 are provided on each side of the watch case 1, a connecting hole 4 is provided on the side wall of the connecting lugs 3, the end of the watch strap 2 is movably installed in the middle of the connecting lugs 3, and a connecting component is provided on the end where the watch strap 2 and the watch case 1 are connected, the connecting component being used to connect the watch case 1 and the watch strap 2 together.

[0030] The connecting component includes a fixing block 8. An inner cavity 6 is provided at the end where the watch strap 2 and the watch case 1 are connected. The fixing block 8 is embedded in the inner cavity 6. A positioning groove 801 is provided on the fixing block 8. A positioning protrusion 802 is provided in the inner cavity 6. The positioning protrusion 802 is engaged in the positioning groove 801. A drive control component is provided inside the fixing block 8. The drive control component is used to control the connection and separation of the watch case 1 and the watch strap 2. The drive control assembly includes an inner tube 11, which is inserted into the fixed block 8. The inner tube 11 is a hollow cylindrical structure with two side holes 14 on both sides of its center. Two connecting rods 13 are movably arranged inside the inner tube 11. The connecting rods 13 are connected to a first locking head 1301 and a second locking head 1302. The first locking head 1301 is located at the open ends of the inner tube 11 and is sleeved on the connecting rods 13. One end of the connecting rod 13 near the opening of the inner tube 11 passes through the side wall of the fixed block 8 and exits through the side wall of the watch strap 2, inserting into the connecting hole 4. This end is smaller than the diameter of the rest. The second locking head 1301... 302 is fixed to the other end of the connecting rod 13. A steel needle 1304 is inserted into the second clamp 1302. The two ends of the steel needle 1304 extend from the side hole 14. A spring 1303 is provided between the first clamp 1301 and the second clamp 1302. The spring 1303 applies a pulling force to the second clamp 1302. A square groove is provided on the fixing block 8. The middle part of the inner tube 11 is located in the square groove. A button 9 is movably inserted into the square groove. Openings are provided on the left and right side walls of the button 9. The inner tube 11 is located in the openings. Side openings 12 are provided on the front and rear side walls of the button 9. The steel needle 1304 is located in the side openings 12.

[0031] The two ends of the side opening 12 are provided with 45° guide rail surfaces 1201. A hook part 1202 is provided below the guide rail surface 1201. The steel needle 1304 abuts against the inner side wall of the side opening 12. The spring 1303 pulls the second hook head 1302 to both sides so that the steel needle 1304 is located in the hook part 1202. When the button 9 is pressed down, the steel needle 1304 is pressed and moves along the guide rail surface 1201, which can make the connecting rod 13 move towards the middle part of the inner tube 11, thereby making the end of the connecting rod 13 move out of the connecting hole 4.

[0032] The watch strap 2 has a mounting groove 7, and the surface of the mounting groove 7 is covered with a film 5. The film 5 is made of a relatively soft material and is used to cover the mounting groove 7 for a more aesthetically pleasing appearance. The mounting groove 7 is connected to the inner cavity 6. A movable part 15 is provided in the mounting groove 7. The movable part 15 is used to limit and hide the button 9. A slot 901 is provided on the side wall of the button 9. The movable part 15 includes a covering part 16 and an embedded part 17. The embedded part 17 is movably disposed in the mounting groove 7. A retaining plate 18 is provided at the connection between the bottom surface of the embedded part 17 and the covering part 16. The retaining plate 18 corresponds to the slot 901. When the retaining plate 18 is inserted into the slot 901, the button 9 is fixed and cannot move. A telescopic elastic member 20 is provided in the mounting groove 7. The telescopic elastic member 20 abuts against the end of the embedded part 17 and applies a pushing force to the embedded part 17, thereby ensuring that the retaining plate 18 can be inserted into the slot 901 when worn.

[0033] The end of the cover portion 16 has an arc-shaped structure for fitting to the bottom of the watch case. A square groove is provided on the bottom surface of the cover portion 16, which matches the shape of the button 9. When the cover portion 16 covers the button 9, it can cover the button 9 to prevent the protrusion from affecting the wearing. Limiting protrusions 19 are provided on both sides of the embedded portion 17, and a limiting slide groove 701 is provided on the inner side wall of the mounting groove 7. The limiting protrusions 19 slide into the limiting slide groove 701, so that the embedded portion 17 can be stably installed in the mounting groove 7.

[0034] During the assembly of the watch strap 2, the fixing block 8 is hot-pressed and bonded to the inside of the inner cavity 6. The inner tube 11 is inserted through the side hole of the watch strap 2. The inner tube 11 is rotated so that the side hole 14 faces upward and the mounting hole on the second clip 1302 faces upward. Then, two steel needles 1304 are inserted into the second clip 1302. The inner tube 11 is rotated so that the steel needles 1304 become horizontal. Then, the exposed parts of the connecting rods 13 at both ends are pressed so that the steel needles 1304 are close to each other. When the distance between the two steel needles 1304 is less than the notch at the bottom of the side opening 12, the button 9 is inserted into the square groove. The connecting rods 13 at both ends are released. At this time, under the influence of the tension of the spring 1303, the connecting rods 13 at both ends move to both sides so that the steel needles 1304 move away from each other and are then locked in the hook part 1202. The assembly is completed.

[0035] When connecting the watch case 1 and the watch strap 2, simply press the button 9 down. The guide rail surface 1201 applies pressure to the steel needle 1304, causing the steel needle 1304 to move the connecting rod 13. When the end of the connecting rod 13 is retracted into the watch strap 2, place the end of the watch strap 2 into the connecting lug 3. Then, the spring 1303 rebounds and pulls the connecting rod 13 back, allowing the end of the connecting rod 13 to be inserted into the connecting hole 4, thus completing the connection. When a component malfunctions and needs to be disassembled for repair, simply press the button 9 during disassembly. This operation is more convenient and applicable to different watch straps 2. Use pliers or tools to press the end 13 of the connecting rod. At this time, the steel needle 1304 will press tightly towards the center and can be detached from the side opening 12, thereby removing the button 9. Compared to other structures on the market, disassembly and repair do not require removing screws, making it faster and more efficient.

[0036] To prevent accidental contact with button 9 during use and to avoid the strap 2 from falling off unexpectedly, a movable part 15 is provided. The telescopic elastic part 20 pushes the movable part 15 forward, so that the card plate 18 is inserted into the card slot 901. The button 9 will not fall down, so the connecting rod 13 can be stably inserted into the connecting hole 4, and the cover part 16 covers the button 9 to prevent the protrusion of the button 9 from affecting the wearing comfort.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
