This is because the two components that are flipped relative to each other need to be limited by concave-convex structures, such as bosses and grooves, after the flipping is realized; so when flipping, it is necessary to use the elastic parts to stretch first, then flip, and finally shrink and reset to achieve the limit. This structure is more complicated, with high requirements for precision, and the elastic parts are prone to failure after repeated use, which affects the user experience. In addition, some flipping structures in the prior art will also destroy the appearance of the watch particles, affecting the user experience.

Furthermore, the first spring ear and/or the second spring ear is a common spring ear, a single-support switch spring ear or a double-support switch spring ear.

For watches, the watch grains are small modules that connect the sections on the watch strap. When you do not want to cut lugs on the watch grains to achieve connection, you can use external connectors to connect the watch grains, which can reduce the difficulty of cutting the watch grains. This is an I-shaped watch strap in the prior art. For this technology, it does not have to be applied to I-shaped watch straps, but can be other types of watch straps.

The two ends of the spring ears can be connected to the strap, or the watch head, all within the protection scope of the present invention. The design of the positioning beads and positioning holes is used to quickly connect and fix the first connection block and the second connection block after flipping to avoid relative position displacement.

There are two implementation methods for the connecting column assembly of some embodiments of the present invention. In one embodiment, the rotating shaft fixing assembly includes a first shaft cover and a second shaft cover; one end of the rotating shaft is fixed to the middle of the first connecting block, and the other end is inserted into the connecting hole; the first shaft cover and the second shaft cover are interlocked to fix the upper and lower sides of the rotating shaft.

Since the rotating shaft has a certain length, there will be a movable area in the middle after it is connected to the first connecting block and the second connecting block, which may cause a gap between the first connecting block and the second connecting block; therefore, the present invention designs a first shaft cover and a second shaft cover for fixing the rotating shaft, and the first shaft cover and the second shaft cover clamp the middle part of the rotating shaft to prevent the rotating shaft from loosening.

Furthermore, the first shaft cover is provided with a through hole, the second shaft cover is provided with a clamping column, and the clamping column passes through the through hole to fix the first shaft cover and the second shaft cover.

In order to make the installation of the shaft and the sleeve more stable, the present invention designs a sleeve, and the shaft is inserted through the entire sleeve; in this embodiment, the shaft is cylindrical, not a structure with bulging at both ends. An L-shaped through hole is opened at the upper end of the second connecting block, so that the pin can be inserted into the second fixing hole and the first fixing hole in sequence.

Preferably, the present invention further comprises decorative sheets attached to the upper and lower surfaces of the second connection block. The decorative sheets not only have an aesthetic effect, but also can seal the L-shaped through hole on the second connection block to form a sealed structure to protect internal components.

Furthermore, a spring ear through hole is provided inside the second connection block, and the spring ear through hole can be used to pass the spring ear through the hole and then connect the watch strap or the watch head.

The wearable device connector of the present invention has a simple overall structure and low cost. The entire watchband flipping structure flips with the central rotating shaft as the central axis, and the positioning after flipping is achieved by the positioning beads, which is easy to operate. In addition, the first connecting block and the second connecting block in the present invention are watch particles, and the opposite side of the connecting surface is not damaged, which will not affect the overall aesthetics.

The wearable device described in this embodiment is a watch, including components such as a dial, a watch particle, and a clasp, and the connector 100 is installed at a certain section or end of a watch strap, as shown in FIG7 .

The first connecting block 1 and the second connecting block 2 are connected by a rotating shaft 3, and the watch strap can be quickly turned over by relatively rotating 180 degrees. Of course, the present invention can also be specifically applied to products such as bracelets that do not require 180-degree turning. The side surface of the first connecting block 1 and the second connecting block 2 that are in relative contact is flat, and the side surface is perpendicular to the horizontal plane where the first connecting block 1 and the second connecting block 2 are located.

As shown in Figures 6 to 9, the connection ends of the first connection block 1 and the second connection block 2 are embedded with positioning beads 5, and the connection surfaces of the second connection block 2 and the first connection block 1 are provided with positioning holes 6 (or positioning grooves) for fixing the positioning beads 5.

As shown in FIGS. 6 and 8 , a first connecting hole 11 is provided in the middle of the first connecting block 1 , and a second connecting hole 21 is provided in the second connecting block 2 . The rotating shaft 3 realizes the rotation connection between the first connecting block 1 and the second connecting block 2 through the first connecting hole 11 and the second connecting hole 21 .

The first connecting hole 11 and the second connecting hole 21 play the role of fixing the rotating shaft 3 and positioning, so that the first connecting block 1 and the second connecting block 2 are rotatably connected. The connecting piece of the present invention can be set at any position of the strap structure of a wearable device such as a watch, a wristband, a bracelet, etc., and by designing two groups of connecting pieces, the flipping of the middle area of the two groups of connecting pieces can be achieved.

At this time, the first connection block 1 is a watch grain, one end of which is connected to the second connection block 2 through the first ear 101, and the other end can be connected to other watch grains through an external connector. For a watch, a watch grain is a small module that connects sections on a watch strap. When you do not want to cut lugs on the watch grain to achieve connection, as shown in Figure 9, an external connector 200 can be used to achieve connection between watch grains; the difficulty of cutting the watch grains can be reduced. This is an I-shaped watch strap in the prior art. For this technology, it is not limited to being applied to I-shaped watch straps, and can be other types of watch straps.

In this embodiment, the first spring ears 101 and the second spring ears 102 are each provided with two sets of single-support switch spring ears or single-sided common spring ears, and the first connecting block 1 and the second connecting block 2 are provided with spring ear blind holes 90 for installing the single-support switch spring ears.

The present invention preferably uses a single-bracket switch spring ear to realize the rotation connection between the table particles. For the connector of the present invention, because the internal shaft 3 needs to be installed and the space is limited, it is preferred to use a single-bracket switch spring ear and design a spring ear blind hole 90 in the first connection block 1 and the second connection block 2, so as to effectively utilize the space. For the connection of table particles at other positions, the spring ear through hole 40 can be selected.

Specifically, the method of using the present invention is to pinch one end of the second connecting block 2 or the first connecting block 1 with your hand, without stretching, and directly flip it over, so that the positioning bead 5 retracts from the positioning hole 6; then the first connecting block 1 rotates around the rotating shaft 3, and when it rotates 180°, the positioning bead 5 contacts the positioning hole 6 to achieve limiting, and the flipping is completed.

Example

As shown in FIG. 10 , the difference between this embodiment and the third embodiment is that a common spring tab is used in conjunction with spring tab through holes 40 designed in the first connection block 1 and the second connection block 2 .

Example

As shown in Figure 11, the difference between this embodiment and Embodiment 3 is that a first magnetic part 201 is embedded in one end where the first connecting block 1 is connected to the second connecting block 2, and a second magnetic part 202 for fixing the first magnetic part 201 is provided at one end where the second connecting block 2 is connected to the first connecting block 1.

The positioning beads 5 and the positioning holes 6 are replaced by the first magnetic member 201 and the second magnetic member 202. In this way, the adjustment is more flexible. Furthermore, the first magnetic member 201 and the second magnetic member 202 are both 2 in number.
