Description
Technical Field
[0001] The present application relates to the technical field of watch strap buckles, and in particular to a watch strap buckle with an anti-disassembly function. Background Art
[0002] A smart watch is a wearable smart device worn on the wrist. It not only has the timing function of a traditional watch, but can also be connected to a smartphone or run independently to provide a variety of intelligent services such as health monitoring, communication, entertainment, and payment.
[0003] When children or elderly people with dementia wear smart watches, it is mainly to connect the smart watches to the mobile phones for real-time positioning, so that the location of the children or elderly people with dementia can be known at any time. The straps connected to the existing smart watches are usually divided into an upper strap and a lower strap. When wearing, the upper strap is usually inserted into the strap buckle on the lower strap, and the connection between the upper strap and the lower strap is adjusted to a suitable wearing size, and then the pin on the strap buckle is plugged into the connecting hole of the upper strap to complete the connection between the upper strap and the lower strap.
[0004] However, the existing smart watches only use the pins on the strap buckle to be plugged into the connecting holes, which results in a simple fixing structure. It is very easy to separate the upper strap from the lower strap to remove the smart watch, so that it is easy for children to take it off when wearing it. As a result, parents cannot ensure that they can know the location of their children through the smart watch, making the device not very safe. Summary of the invention

[0007] Further, fixing pieces are fixedly connected to both ends of the connecting rod respectively. The two U-shaped pieces are located between the two fixing pieces, and the inner diameter of the fixing piece is smaller than that of the through hole.
[0008] Further, an installation groove is formed in the top surface of the chassis. A bending elastic piece is fixedly installed in the installation groove. Two protruding parts are arranged on the top surface of the bending elastic piece, and the tops of the two protruding parts respectively abut against the bottom surface of the fixing plate.
[0009] Further, connecting blocks are fixedly installed on the top surfaces of the two U-shaped pieces respectively. The spring is sleeved on the outer periphery of the connecting block and is fixedly connected.
[0010] Further, the arc surfaces of the two springs respectively abut against the side walls in the two placement grooves.
[0011] Further, the unlocking assembly includes a connecting piece, a plugging rod and a fixing block. The top end of the plugging rod is fixedly installed at the bottom of the connecting piece. The plugging rod is located between the two U-shaped pieces. The plugging rod is plugged into the jack, and the plugging rod is located between the two U-shaped pieces. There are two fixing blocks, and the two fixing blocks are respectively fixedly installed on the arc surface of the plugging rod and are symmetrical to each other.
[0012] Further, the side of the fixing block away from the plugging rod is set as an arc surface.
[0013] Further, a connecting groove is formed in the top surface of the fixing plate. The plugging rod abuts against the bottom surface of the connecting groove.
[0014] Further, four connecting holes are formed in the top surface of the fixing plate and are arranged in a rectangular array on the top surface of the fixing plate. The connecting assembly includes connecting cylinders and fixing rods. There are four connecting cylinders and four fixing rods respectively. The four fixing rods are respectively fixedly connected in the four connecting cylinders. The ends of the four fixing rods away from the connecting cylinders are respectively fixedly connected in the four connecting holes.

Detailed implementation mode
[0019] The following further elaborates on this application in conjunction with the attached drawings.
[0020] Example, refer to Figures 1-8A watch band buckle with anti-disassembly function comprises a watch body 6, on which a base frame 1, a buckle surface 2 and a fixing plate 3 are fixedly installed respectively, a rotating rod 11 is fixedly installed between the two sides of the base frame 1, the buckle surface 2 is rotatably connected to the rotating rod 11, and the top surface of the fixing plate 3 is provided with two placement grooves 31, which are symmetrical to each other, and springs 32 are fixedly connected in the two placement grooves 31 respectively, and the opposite ends of the two springs 32 are fixedly connected with U-shaped pieces 33 respectively, and the bottom surfaces of the two U-shaped pieces 33 are respectively slidably connected to the top surface of the fixing plate 3, and the bottom surface of the base frame 1 is close to the top surface of the fixing plate 3. A connecting rod 12 is fixedly installed on one side near the U-shaped piece 33, a through hole 34 is provided on the top surface of the fixing plate 3, the connecting rod 12 runs through the through hole 34, the connecting rod 12 is located between the two U-shaped pieces 33, and the two U-shaped pieces 33 are close to the connecting rod 12. The side of the connecting rod 12 is attached to the arc surface of the connecting rod 12. A connecting component 4 for connecting the buckle surface 2 is fixedly installed on the fixing plate 3, a plug hole 21 is provided on the top surface of the buckle surface 2, and runs through the top surface of the buckle surface 2. The plug hole 21 is provided with an unlocking component 5 for contacting the two U-shaped pieces 33 and allowing the U-shaped pieces 33 to compress the spring 32. The watch body 6 is generally composed of a display, a fixing buckle, an upper strap and a lower strap, and then the bottom frame 1 and the buckle surface 2 are fixedly installed on the upper strap through the connecting rod 12, and then the lower strap is plugged into the bottom frame 1 and fixed through the buckle surface. When the unlocking device is needed, first pull the lower strap out of the fixed buckle to expose the socket 21 on the buckle surface 2, and insert the unlocking component 5 into the socket 21 so that the unlocking component 5 is inserted between the two U-shaped pieces 33, and the unlocking component 5 contacts the side of the two U-shaped pieces 33 close to the unlocking component 5, and then rotate the unlocking component 5 to squeeze the two U-shaped pieces 33, so that the two U-shaped pieces 33 compress the spring 32 respectively, so that the two U-shaped pieces 33 are away from the connecting rod 12, and then rotate the buckle surface 2 to make the buckle surface 2 rotate on the rotating rod 11, so that the connecting rod 12 is disengaged from the through hole 34, so that the base frame 1 and the buckle surface 2 are unlocked. When the device needs to be locked, the unlocking component 5 is inserted into the through hole 34, and the buckle surface 2 and the base frame 1 are closed, and the unlocking component 5 is rotated to make the U-shaped piece 33 compress the spring 32. As the buckle surface 2 and the base frame 1 are merged, the connecting rod 12 is connected to the through hole 34. Then, by removing the unlocking component 5, the two springs 32 rebound, and the two U-shaped pieces 33 slide on the top surface of the fixed plate 3 toward relative positions, so that the opposite sides of the two U-shaped pieces 33 abut against the arc surface of the connecting rod 12, so that the two U-shaped pieces 33 clamp the connecting rod 12, so that the buckle surface 2 and the base frame 1 are merged and locked, preventing arbitrary unlocking and improving the safety of the device.
[0021] Reference Figure 3 as well as Figure 4, fixing pieces 13 are fixedly connected to both ends of the connecting rod 12 respectively. Two U-shaped pieces 33 are located between the two fixing pieces 13, and the inner diameter of the fixing piece 13 is smaller than the inner diameter of the through hole 34. When the device is locked, when the buckle surface 2 and the chassis 1 are closed, the connecting rod 12 is inserted into the through hole 34, the fixing piece 13 is located outside the through hole 34, and the U-shaped piece 33 slides inwards under the action of the spring 32 to clamp the connecting rod 12. At the same time, the fixing piece 13 restricts the axial movement of the connecting rod 12 to ensure stable locking. When unlocking the device, since the inner diameter of the fixing piece 13 is smaller than the inner diameter of the through hole 34, the connecting rod 12 and the fixing piece 13 are separated from the through hole 34, improving the stability of the device.
[0022] Refer to Figure 2 and Figure 3 , an installation groove 14 is formed on the top surface of the chassis 1, a bent elastic piece 15 is fixedly installed in the installation groove 14, two protruding parts 151 are arranged on the top surface of the bent elastic piece 15, and the tops of the two protruding parts 151 respectively abut against the bottom surface of the fixing plate 3. When the device is locked, the bottom surface of the fixing plate 3 abuts against the tops of the two protruding parts 151 on the bent elastic piece 15. By utilizing the elasticity of the bent elastic piece 15, as the chassis 1 and the buckle surface 2 are combined, the bent elastic piece 15 is squeezed by the bottom surface of the fixing plate 3 to form an elastic contact, avoiding wear. When unlocking the device, the bent elastic piece 15 rebounds to lift the fixing plate 3, enabling the device to be quickly unlocked and improving the convenience of the device.
[0023] Refer to Figure 2 , connection blocks 35 are fixedly installed on the top surfaces of the two U-shaped pieces 33 respectively, and the spring 32 is sleeved on the outer periphery of the connection block 35 and fixedly connected. When unlocking or locking the device, the U-shaped piece 33 compresses the spring 32, or the spring 32 rebounds to reset the U-shaped piece 33. Taking the connection block 35 as the installation base of the spring 32, the telescopic direction of the spring 32 is always consistent with the sliding direction of the U-shaped piece 33, avoiding deflection and improving the stability of the device. The spring 32 directly acts on the U-shaped piece 33 through the connection block 35, reducing energy loss, increasing the response speed of locking or unlocking, and improving the working efficiency of the device.
[0024] Refer to Figure 2 , the arc surfaces of the two springs 32 respectively abut against the side walls in the two placement grooves 31. When unlocking or locking the device, the two springs 32 are compressed by the U-shaped piece 33, or the two springs 32 rebound and reset. The side walls of the placement groove 31 perform radial limiting on the arc surfaces of the springs 32 to ensure that the springs 32 move linearly during compression or extension, avoiding jamming of the U-shaped piece 33 caused by lateral force and improving the locking reliability of the device.
[0025] Refer to Figure 1 and Figure 4, the unlocking component 5 includes a connecting piece 51, a plugging rod 52 and a fixing block 53. The top end of the plugging rod 52 is fixedly installed at the bottom of the connecting piece 51. The plugging rod 52 is located between two U-shaped pieces 33. The plugging rod 52 is plugged into the jack 21, and the plugging rod 52 is located between two U-shaped pieces 33. There are two fixing blocks 53, and the two fixing blocks 53 are respectively fixedly installed on the arc surface of the plugging rod 52 and are symmetrical to each other. When the unlocking component 5 is plugged into the through hole 34, the plugging rod 52 is plugged into the jack 21, so that the plugging rod 52 is located between two U-shaped pieces 33. The user can rotate the connecting piece 51 to make the plugging rod 52 rotate in the jack 21. As the plugging rod 52 rotates, one side of the two fixing blocks 53 on the plugging rod 52 respectively abuts against one side of the two U-shaped pieces 33, so that the two U-shaped pieces 33 respectively compress the spring 32, thereby making the two U-shaped pieces 33 move away from the connecting rod 12, improving the safety of the device.
[0026] Refer to Figure 4 , the side of the fixing block 53 away from the plugging rod 52 is set as an arc surface. When the plugging rod 52 rotates, the arc surfaces of the two fixing blocks 53 respectively abut against one side of the two U-shaped pieces 33, so that the U-shaped pieces 33 are compressed. Through the arc surface, the wear of the fixing block 53 when abutting against the U-shaped piece 33 is reduced, thereby increasing the service life of the device.
[0027] Refer to Figure 2 and Figure 4 , a connecting groove 16 is provided on the top surface of the fixing plate 3. The plugging rod 52 abuts against the bottom surface of the connecting groove 16. When the plugging rod 52 is plugged into the jack 21 and the bottom end of the plugging rod 52 is connected to the connecting groove 16 and abuts against the bottom surface of the connecting groove 16, axial limitation is formed, ensuring that the insertion depth of the plugging rod 52 is the same each time, preventing over-insertion or shaking, and improving the service life of the device.
[0028] Refer to Figure 5 , four connecting holes 36 are opened on the top surface of the fixing plate 3 and are arranged in a rectangular array on the top surface of the fixing plate 3. The connecting component 4 includes a connecting cylinder 41 and a fixing rod 42. There are four connecting cylinders 41 and four fixing rods 42 respectively. The four fixing rods 42 are respectively fixedly connected in the four connecting cylinders 41. The ends of the four fixing rods 42 away from the connecting cylinders 41 are respectively fixedly connected in the four connecting holes 36. The four connecting cylinders 41 are fixedly installed on the bottom surface of the buckle surface 2 and are arranged in a rectangular array. When assembling the fixing plate 3 and the buckle surface 2, the four fixing rods 42 are respectively aligned with the four connecting holes 36. When the fixing plate 3 and the buckle surface 2 are combined together, the four fixing rods 42 are respectively plugged into the connecting holes 36, and they can be fixed by injection molding, improving the convenience of the device.
[0029] Working principle: 1. When the device needs to be locked, insert the insertion rod 52 into the jack 21, rotate the rotating rod 11, and the buckling surface 2 rotates along with the rotating rod 11, then the fixing plate 3 rotates, causing the buckling surface 2 to close with the chassis 1. Then, the fixing plate 3 abuts against the convex part 151 of the bending elastic piece 15, compressing it. Rotate the insertion rod 52 so that the two fixing blocks 53 on the insertion rod 52 respectively abut against the two U-shaped pieces 33. Then, the two U-shaped pieces 33 respectively compress the two springs 32. As the buckling surface 2 and the chassis 1 are combined, the connecting rod 12 is connected to the through hole 34. Then, by removing the insertion rod 52, the two springs 32 rebound, causing the two U-shaped pieces 33 to slide on the top surface of the fixing plate 3 towards the relative positions. Thus, the relative sides of the two U-shaped pieces 33 abut against the arc surface of the connecting rod 12, realizing that the two U-shaped pieces 33 clamp the connecting rod 12, thereby completing the combination and locking of the buckling surface 2 and the chassis 1, preventing random unlocking, and improving the safety of the device.
[0030] 2. When the device needs to be unlocked, insert the insertion rod 52 into the jack 21 so that the insertion rod 52 is inserted between the two U-shaped pieces 33. By rotating the insertion rod 52, the two fixing blocks 53 on the insertion rod 52 respectively squeeze the two U-shaped pieces 33. Then, the two U-shaped pieces 33 respectively compress the springs 32, causing the two U-shaped pieces 33 to move away from the connecting rod 12. Then, by rotating the buckling surface 2, the buckling surface 2 rotates on the rotating rod 11, causing the connecting rod 12 to disengage from the through hole 34, thereby completing the unlocking between the chassis 1 and the buckling surface 2, improving the convenience of the device.
[0031] The embodiments of this specific implementation manner are all preferred embodiments of this application. Without limiting the protection scope of the application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
