Technical Field
[0001] This utility model relates to the field of silicone watch strap technology, and in particular to a silicone watch strap that is easy to detach and connect to the watch face. Background Technology
[0002] Smartwatches, as the name suggests, are ordinary watches that have been given a smart upgrade. The biggest feature of smartwatches is that they integrate multiple functions, making things more convenient for us. In addition to telling time, smartwatches can also measure a person's blood pressure, heart rate, record exercise time, check the weather, make mobile payments, and have NFC, among other functions.
[0003] Currently, when changing the watch band on a smartwatch, a long needle is needed to insert into the spring bar, press the needle down, and remove the band from both ends of the watch. Then, the long needle is used to install the new band. This process is inconvenient. In addition, the spring bar is usually an integral part of the watch band. When the internal spring of the spring bar is damaged after long-term use, it needs to be replaced along with the watch band, which is costly. Utility Model Content
[0004] The purpose of this invention is to provide a silicone watch strap that is easy to detach and connect to the watch face, addressing the shortcomings of existing technologies.

The first connection structure includes a connecting seat formed at the end of the strap body, a connecting cavity formed in the connecting seat, and hinge pins that can protrude outwards at both ends of the connecting cavity. A hinge pin that connects to the watch face is installed at the outer end of the hinge pin. A rotatable drive shaft is installed in the connecting cavity. The inner end of the hinge pin is movably connected to the drive shaft. A plastic gear is sleeved on the drive shaft. The drive shaft rotates to drive the two hinge pins to move closer or further apart.
[0007] Furthermore: the cross-section of the connecting cavity is circular, and guide sleeves for the hinged column to move axially in the connecting cavity are installed at both ends of the connecting cavity. The inner end of the hinged column is formed with a limiting sleeve that cooperates with the inner end stop of the guide sleeve.
[0008] Furthermore, the inner end of the hinge column is axially formed with a concave drive groove for the drive shaft to be inserted.
[0009] Furthermore, the two ends of the drive shaft are respectively formed with external thread structures in opposite directions, and a transmission sleeve that is in transmission engagement with the external thread structure of the drive shaft is installed in the drive groove.
[0010] Furthermore: the connecting seat is formed with an actuation groove for exposing the plastic gear, and one end of the actuation groove is hinged with a hinged cover that can be flipped.
[0011] Furthermore: a fitting block is installed at the other end of the hinge cover, and a fitting groove is formed at the other end of the actuating groove for the fitting block to be elastically inserted.
[0012] Furthermore: one of the watch strap bodies is formed with a plurality of spaced positioning holes along its length, and a positioning sleeve is slidably mounted on the watch strap body.
[0013] Furthermore, a buckle is installed at the outer end of another of the watch strap bodies, and the buckle can engage with one of the positioning holes.
[0014] The beneficial effects of this utility model are as follows: When connecting the watch strap to the watch face, the watch strap is fitted to the watch face, and the hinge pin with the hinge pin is coaxially aligned with the hole in the watch face. Then, the plastic gear is turned, causing the drive shaft to rotate. The drive shaft and the hinge pin in the drive cavity are in a transmission engagement, which can drive the two hinge pins to move closer or further apart, so that the hinge pin installed on the hinge pin is inserted into the hole in the watch face, thus achieving the connection. This saves on the design of springs, reduces costs, facilitates disassembly, and extends the service life. Attached Figure Description

[0024] The present invention will now be described in detail with reference to the accompanying drawings.
[0025] like Figure 1-3 As shown, a silicone watch strap that is easy to detach and connect to a watch face includes a watch strap body 1 made of silicone material. One end of the watch strap body 1 is provided with a first connection structure 10 for connecting to the watch face. The first connection structure 10 includes a connecting seat 11 formed at the end of the watch strap body 1. A connecting cavity 12 is formed in the connecting seat 11. Hinged pins 13 that can protrude outward are respectively provided at both ends of the connecting cavity 12. A hinge pin 14 for connecting to the watch face is installed at the outer end of the hinge pin 13. A rotatable drive shaft 15 is installed in the connecting cavity 12. The inner end of the hinge pin 13 is movably connected to the drive shaft 15. A plastic gear 22 is sleeved on the drive shaft 15. The drive shaft 15 rotates to drive the two hinge pins 13 away from each other.
[0026] When connecting the watch strap to the dial, align the watch strap with the dial, and align the hinge pin 13 (with hinge pin 14) coaxially with the hole in the dial. Then, turn the plastic gear 22 to rotate the drive shaft 15. The drive shaft 15 engages with the hinge pin 13 in the drive cavity, causing the two hinge pins 13 to move closer or further apart, allowing the hinge pin 14 installed on the hinge pin 13 to be inserted into the hole in the dial, thus achieving the connection. This eliminates the need for a spring, reduces costs, facilitates disassembly, and extends the service life.
[0027] Specifically, the connecting cavity 12 has a circular cross-section. Guide sleeves 16 are installed at both ends of the connecting cavity 12 to allow the hinge pin 13 to move axially within the cavity. A limiting sleeve 17 is formed at the inner end of the hinge pin 13, which cooperates with the inner end stop of the guide sleeve 16. Under the limiting effect of the guide sleeve 16, the hinge pin 13 can move axially within the connecting cavity 12, ensuring that the hinge pin 14 installed on the hinge pin 13 can be coaxially connected with the hole on the dial, thus ensuring the stability of the connection.
[0028] The inner end of the hinge post 13 has an axially formed concave drive groove 18 for the drive shaft 15 to be inserted. Both ends of the drive shaft 15 have oppositely oriented external thread structures 20. A transmission sleeve 19, which engages with the external thread structure 20 of the drive shaft 15, is installed in the drive groove 18. In this embodiment, when the drive shaft 15 is rotated, the external thread structure 20 of the drive shaft 15 engages with the transmission sleeve 19, allowing the hinge post 13 to rotate axially. The hinge pin 14, installed at the outer end of the hinge post 13, can move closer to or further away from the hole on the dial, enabling connection and disassembly.
[0029] The connecting seat 11 has a rotating groove 21 for exposing the plastic gear 22. One end of the rotating groove 21 is hinged to a hinge cover 23 that can be flipped. The other end of the hinge cover 23 is fitted with a fitting block 24, and the other end of the rotating groove 21 has a fitting groove 25 for the fitting block 24 to be elastically inserted. In this embodiment, by rotating the plastic gear 22, the drive shaft 15 can rotate within the connecting cavity 12, thereby engaging with the hinge column 13 and driving the hinge column 13 to move. When the watch strap is connected to the watch face, the hinge cover 23 is flipped. The hinge cover 23 engages with the fitting groove 25 of the rotating groove 21 through the fitting block 24 to cover and prevent the plastic gear 22 from being exposed, thus preventing the drive shaft 15 from rotating.
[0030] One of the watch strap bodies 1 has multiple spaced positioning holes 26 formed along its length, and a positioning sleeve 27 is slidably mounted on the watch strap body 1. A buckle 28 is mounted on the outer end of the other watch strap body 1, and the buckle 28 can engage with one of the positioning holes 26. The two watch straps can be connected by the engagement of the buckle 28 and the positioning hole 26, forming a loop structure. It should be noted that the connection between the two watch straps using the buckle 28 and the positioning hole 26 is a common existing connection method; the specific connection method will not be elaborated upon here.
[0031] Preferably, the main body 1 of the watch strap is formed with a guide groove 29 along its length. The guide groove 29 is located on both sides of the positioning hole 26 to enhance the overall aesthetic design.
[0032] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
[0033] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
