[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.
[0021] Reference Figure 1 - Figure 5 As shown, the utility model provides a technical solution: an anti-falling ear connector, comprising a dial 1, a watch strap 2 is provided at the bottom of the dial 1, a first ear rod 3 and a second ear rod 4 are provided inside the dial 1, one end of the first ear rod 3 is fixedly connected to a connecting rod 17, and the end of the connecting rod 17 close to the second ear rod 4 is fixedly connected to a connecting plate 18, and the connecting plate 18 is slidably connected to the inside of the second ear rod 4, a control groove 5 is provided at one end of the second ear rod 4, a rotating column 6 is rotatably connected to the inside of the control groove 5, an anti-falling block 7 is provided inside the rotating column 6, an arc block 8 is fixedly connected to the inner wall of the control groove 5, an adjusting groove 9 is provided at both ends of the rotating column 6, a through hole 10 is provided at the bottom of the adjusting groove 9, a push block 11 is slidably connected to the inside of the adjusting groove 9, and an insert block 12 is fixedly connected to the side of the push block 11 close to the inside of the adjusting groove 9, and a plug hole 1 is provided on the surface of the anti-falling block 7 3. A threaded rod 23 is provided inside the second ear rod 4, and thread grooves 22 are provided at both ends of the rotating column 6. The bottom of the pushing block 11 is fixedly connected to the storage spring 14, and the bottom of the storage spring 14 is fixedly connected to the inside of the through hole 10. The staff first releases the limit between the threaded rod 23 and the threaded groove 22 so that the rotating column 6 can rotate alone. The staff rotates the anti-slip block 7, and the anti-slip block 7 is inserted in the insertion block 12 to drive the rotating column 6 to rotate. When the staff releases the limit between the pushing block 11 and the arc block 8, the storage spring 14 is set to make the storage spring 14 push the pushing block 11, and the pushing block 11 drives the insertion block 12 to release the limit between it and the hole 13, and the limit of the anti-slip block 7 is also released. The staff disassembles the anti-slip block 7, thereby achieving the purpose of installing and disassembling the watchband 2 and preventing the watchband 2 from falling off from the inside of the dial 1.
[0022] Reference Figure 4 and Figure 5 As shown, in this embodiment: slide grooves 15 are provided on both sides of the rotating column 6, and sliders 16 are fixedly connected to both sides of the push block 11. The surface of the slider 16 is slidably connected to the inside of the slide groove 15. When the staff moves the push block 11, the push block 11 drives the slider 16 to slide inside the slide groove 15. Through the above arrangement, stable support and precise guidance of the push block 11 are achieved. In addition, the sliding friction of the slider 16 is small, which ensures the smooth movement of the push block 11, thereby improving the convenience of operation and the service life of the equipment.
[0023] Reference Figure 2As shown, in this embodiment: a side of the connecting plate 18 close to the first ear rod 3 is fixedly connected to a rebound spring 19, and a side of the rebound spring 19 away from the guide block 21 is fixedly connected to the inside of the first ear rod 3. When the staff pulls the second ear rod 4, the second ear rod 4 drives the rebound spring 19 to compress and store force, and at the same time exposes the second ear rod 4 to the outside, so that the staff can prevent the watch strap 2 from falling off. When the staff releases the second ear rod 4, the rebound force of the rebound spring 19 quickly drives the second ear rod 4 to move toward the middle, and the first ear rod 3 and the second ear rod 4 are hidden inside the dial 1.
[0024] Reference Figure 2 As shown, in this embodiment: guide grooves 20 are provided at both ends of the second ear rod 4, and guide blocks 21 are fixedly connected to both sides of the connecting plate 18. The surface of the guide block 21 is slidably connected to the inside of the guide groove 20. When the staff moves the connecting plate 18, the connecting plate 18 drives the guide block 21 to slide inside the guide groove 20. Through the above arrangement, precise control of the position of the connecting plate 18 is achieved. In addition, the sliding friction of the guide block 21 is small, which ensures the smooth movement of the connecting plate 18 and reduces the resistance during operation to prevent external dust and impurities from entering, thereby ensuring the cleanliness of the internal mechanical structure and the long-term stable operation of the equipment.
[0025] Reference Figure 1 - Figure 5 As shown, in this embodiment: the size of the plug block 12 is adapted to the size of the socket 13, and the surface of the plug block 12 is plugged into the interior of the socket 13. By setting the size of the plug block 12 to be adapted to the size of the socket 13, a tight connection between the component plug block 12 and the socket 13 is ensured, thereby improving the stability and durability of the overall structure. In addition, this design also facilitates rapid replacement and maintenance of components.
[0026] Working principle: The staff first releases the limit between the threaded rod 23 and the threaded groove 22, so that the rotating column 6 can rotate independently. The staff rotates the anti-slip block 7, and the anti-slip block 7 is inserted into the plug block 12 through the plug block 12 to drive the rotating column 6 to rotate. When the staff releases the limit between the push block 11 and the arc block 8, the storage spring 14 is set to push the push block 11, and the push block 11 drives the plug block 12 to release the limit between it and the socket 13, and the limit of the anti-slip block 7 is also released. The staff adjusts the anti-slip block 7. 7 is disassembled to achieve the purpose of installing and disassembling the watch band 2 and prevent the watch band 2 from falling off from the inside of the dial 1. When the staff moves the push block 11, the push block 11 drives the slider 16 to slide inside the slide groove 15. Through the above arrangement, stable support and precise guidance of the push block 11 are achieved. In addition, the sliding friction of the slider 16 is small, which ensures the smooth movement of the push block 11, thereby improving the convenience of operation and the service life of the equipment. When the staff pulls the second ear rod 4, the second ear rod 4 drives the return spring 19 to compress and accumulate force, while exposing the second ear rod 4 to the outside so that the staff can prevent the strap 2 from falling off. When the staff releases the second ear rod 4, the return spring 19 quickly drives the second ear rod 4 to move toward the middle under the action of the rebound force, so that the first ear rod 3 and the second ear rod 4 are hidden inside the dial 1. When the staff moves the connecting plate 18, the connecting plate 18 drives the guide block 21 to slide inside the guide groove 20. Through the above arrangement, precise control of the position of the connecting plate 18 is achieved. In addition, the sliding friction of the guide block 21 is small, ensuring smooth movement of the connecting plate 18 and reducing resistance during operation, thereby preventing external dust and impurities from entering, ensuring the cleanliness of the internal mechanical structure and the long-term stable operation of the equipment. The size of the plug block 12 is matched with the size of the socket 13, ensuring a close connection between the component plug block 12 and the socket 13, thereby improving the stability and durability of the overall structure. In addition, this design also facilitates rapid replacement and maintenance of components.
