[0028] Refer to the accompanying drawings. The present invention provides a sliding hinge comprising a first connector 1 and a second connector 2, which are slidably connected. The first connector 1 and the second connector 2 can serve as connecting components of the sliding hinge applied to a wearable device, respectively connecting to two structures in the wearable device that need to slide relative to each other.

[0029] The sliding hinge is further provided with a locking structure, and the locking structure is provided with an operating component, and the operating component is movably mounted on the second connecting body 2. In this embodiment, the operating component is a button 3.

[0030] A movable connecting rod 4 is provided between the first connecting body 1 and the second connecting body 2, a rolling body lock 5 is provided on the connecting rod 4, a connecting rod bracket 6 is provided on the first connecting body 1, the connecting rod 4 is movably located on the connecting rod bracket 6, a locking groove 60 is provided on the connecting rod bracket 6, the rolling body lock 5 is located in the locking groove 60, and the inner side of the button 3 is connected to the cam 7, the cam surface of the cam 7 cooperates with the connecting rod 4 to drive the connecting rod 4 to move, and then drives the rolling body lock 5 to move in the locking groove 60, the locking groove 60 0 has a width variation section corresponding to the rolling surface of the rolling element lock (for example, if a cylinder is used in this embodiment, then its cylindrical surface). When the rolling element lock 5 moves to the wide portion 601 of the width variation section, the sliding hinge is unlocked, and when it moves to the narrow portion 602 of the width variation section, the sliding hinge is locked. The width variation section can be a groove section in which one side groove wall is arc-shaped or inclined relative to the other side groove wall. The locking structure is further provided with a reset elastic element 8 to reset the connecting rod 4 and the rolling element lock 5 when the operating component is released.

[0031] The connecting rods 4 are arranged in pairs, forming a pair of first connecting rods ( Figure 3 、 4 The left link 4 is shown) and the second link ( Figure 3 、 4 The reset elastic element 8 is set between the connecting rod 4 on the right side of the drawing, and the first connecting rod and the second connecting rod are respectively connected with a rolling element lock 5, each rolling element lock 5 has its own width variation section, and the rolling element lock of the first connecting rod ( Figure 3 、 4 The left rolling element lock 5) and the second rolling element lock ( Figure 3 、 4 The movement direction of the rolling element lock 5 on the right side is opposite, and the width change section ( Figure 3 、 4 The width change direction of the width change section on the left side of the locking groove 60 shown in FIG) is consistent with the width change section corresponding to the rolling element lock of the second connecting rod ( Figure 3 、 4 The width change section on the left side of the locking groove 60 shown in the figure has a width change direction opposite to that of the width change section. This ensures that the one-way locking effect is achieved after sliding adjustment in both directions. The locking force does not depend on the force of the resetting elastic element 8, which ensures the locking effect while making operation easier.

[0032] The connecting rod bracket 6 is provided with a mounting groove 61 of the connecting rod 4, and the lower parts of the first connecting rod and the second connecting rod are inserted into the mounting groove. The mounting groove 61 guides and cooperates with the first connecting rod and the second connecting rod in the direction of the connecting rod movement.

[0033] The resetting elastic elements 8 are respectively provided between the upper parts and the lower parts of the pair of connecting rods 4 , and the resetting elastic elements 8 can be compression springs.

[0034] For the connecting rod 4 that forms a pair, the cam surface of the cam 7 also forms a pair. The cam surface that forms a pair includes a first control bevel 71 and a second control bevel 72, which correspond to the first connecting rod and the second connecting rod respectively. In addition, the first connecting rod and the second connecting rod are respectively provided with a surface 41 that cooperates with the first control bevel 71 and a surface 42 that cooperates with the second control bevel 72, so that the pressing operation is more comfortable and smooth.

[0035] The rolling element lock 5 is rotatably mounted on the connecting rod 4. For example, a cylinder can be used, which is connected to the connecting rod 4 through an axis 51 and can rotate relative to the connecting rod 4. Alternatively, the rolling element lock 5 can be a bearing, which is mounted on the connecting rod and has a rotatable outer ring.

[0036] The sliding hinge is also provided with a connecting block 9, a sliding guide groove 11 is provided on the first connecting body 1, the second connecting body 2 is located on the front side of the first connecting body 1, and the connecting block 9 is located on the other side of the first connecting body 1 and is connected to the second connecting body 2 by screws. The second connecting body 2 includes a shell, and the connecting rod 4, rolling body lock 5, connecting rod bracket 6 and reset elastic element 8 are arranged inside the shell; a guide block 91 is provided on the connecting block 9 to cooperate with the sliding guide groove 11 on the first connecting body.

[0037] The sliding hinge is provided with the locking structures on both sides of the guide block, so that the locking is more stable.

[0038] The cam surface is configured to unlock when the operating member is operated. When the operating member is released, the lock state is automatically entered via the resetting elastic element 8. This self-locking function remains in effect regardless of the direction of sliding. This ensures reliable locking and facilitates operation, particularly when locking structures are provided on both sides as described above. In this case, as shown in the figure, the cam's slope can be configured to be lower on the outside and higher on the inside. When the button is released, the rolling element lock 5 is held in place by the spring force. When the second connector 2 moves leftward, the left rolling element lock 5 is continuously clamped (at the narrow width variation section 602), securing the second connector 2. When the second connector 2 moves rightward, the right rolling element lock 5 is continuously clamped, securing the second connector 2, achieving a locking effect. When the button is pressed, unlocking occurs: the rolling element lock 5 is pulled toward the center (at the wide width variation section 601) by the connecting rod 4.

[0039] The connecting rod is tilted toward one of the sliding directions, which can reduce the size of the product in a direction perpendicular to the first connector 1 without affecting the movement effect and the locking effect.

[0040] The operating component may also be a front-to-back sliding operating block. In this case, the direction of the connecting rod and the locking slot of the present invention may be horizontally flipped 90° for application.
