The guide frame has a transverse hole open to the locking groove. The locking block is slidably installed in the transverse hole. The locking block has a vertical connecting hole, and the upper part of the adjusting member is inserted into the vertical connecting hole of the locking block. The upper parts of the locking block and the adjusting member are connected by a connecting shaft. The locking block and the guide frame are respectively provided with an oblique hole and a vertical hole. The connecting shaft is fixed on the adjusting member and passes through both the oblique hole and the vertical hole.

[0010] The lower part of the adjusting element and the screw part of the adjusting knob are threadedly connected.

[0011] Within the stroke range of the locking block, the locking block can be tightly engaged with the locking groove.

[0012] The first connecting part is a protruding part on the side of the first connecting body, with a larger front end and a smaller rear end. The guide frame is located in the first connecting part. The second connecting part is a slot with the groove facing the first connecting body and opening downwards. The locking groove is located at the bottom of the slot.

[0013] The wearable device is AR glasses. The first connector is connected to the temple, the second connector is connected to the frame, and multiple second connectors are arranged along the front-to-back direction.

[0014] By adopting the technical solution of this utility model, the user can directly disassemble and adjust the position of the functional structure connected to the hinge relative to the hinge, such as adjusting the position of the frame in the front and back direction, so that the user can choose the installation position according to their own characteristics.

[0021] Referring to the accompanying drawings, this embodiment takes AR glasses as an example. The adjustable hinge structure includes a first connecting body 1 and a second connecting body 2. The first connecting body 1 is connected to the temple, and the second connecting body 2 is connected to the frame. This embodiment allows users to select the front and rear installation positions of the frame. Through simple operation, users can easily install and connect the glasses themselves to adapt the product to their own face shape.

[0022] The first connector 1 has a first connecting part 11, and the second connector 2 has multiple second connecting parts 21 that are inserted into the first connecting part 11. These multiple second connecting parts are arranged along the front-to-back direction. By inserting the first connecting part 11 into one of the second connecting parts 21, the position of the second connector relative to the first connector can be adjusted. After insertion, the first connector 1 and the second connector 2 are engaged. This engagement can be a mortise and tenon structure, as shown in the figure. The first connecting part has a structure that is larger at the front end and slightly smaller at the rear end, protruding laterally from the side of the first connector. Correspondingly, the second connecting part 21 is a slot with a groove 211 facing the first connector and opening downwards 212, so that the insertion operation can be performed from top to bottom. The direction of engagement is perpendicular to the direction of insertion.

[0023] The adjustable hinge structure is further provided with an adjustable lock for locking the first connecting body 1 and the second connecting body 2. The adjustable lock includes an adjusting member 31, an adjusting knob 32, and a locking block 33. The adjusting knob 32 is connected to the adjusting member 31 and is used to drive the adjusting member 31 to move. The adjusting member 31 is connected to the locking block 33. The locking block 33 is used to lock the insertion of the first connecting body 1 and the second connecting body 2 to prevent the second connecting body 2 from being pulled out and to tighten the gap between the first connecting body 1 and the second connecting body 2, thereby improving the connection strength and preventing the internal structure from shaking. The movement of the adjusting member 31 drives the movement of the locking block 33 to unlock, lock, and tighten.

[0024] In this embodiment, a more compact structure, smaller footprint, and easier manufacturing solution is also provided for the adjustable lock: the first connecting body 1 includes an internally fixed guide frame 10 (which may have an internal mounting hole in the body of the first connecting body 1, with the guide frame 10 fixed in the mounting hole by bonding or interference fit), the guide frame 10 has a vertical connecting hole 12, and preferably the guide frame 10 is located in the first connecting part 11. The adjusting member 31 is located in the vertical connecting hole and can be raised and lowered, and the adjusting member 31 and the first connecting body 1 have a raising and lowering guide fit. The vertical connecting hole 12 in the guide frame 10 can serve as a raising and lowering guide hole for the adjusting member 31. The locking block 33 is a horizontally moving component, and the second connecting body 2 has a locking groove 22 that mates with the locking block 33. The locking groove 22 can be located at the bottom of the slot (second connecting part 21).

[0025] The adjusting knob 32 is an adjusting knob threadedly connected to the adjusting member 31. The adjusting knob 32 is axially positioned on the first connecting body 1. Reference numeral 4 is a U-shaped positioning member that is inserted into and mounted on the first connecting body 1, engaging with the adjusting knob 32 to axially position it. The guide frame 10 has a transverse hole 13 open to the locking groove 22. The locking block 33 is slidably installed in the transverse hole 13. The locking block 33 has a vertical connecting hole, and the upper part of the adjusting member 31 is inserted into the vertical connecting hole in the locking block 33. The upper end of the adjusting member 31 and the adjusting member 31 are connected by a connecting shaft 5. The locking block 33 and the guide frame 10 are respectively provided with an oblique hole 331 and a vertical hole 101. The connecting shaft 5 is fixed to the upper part of the adjusting member 31 and passes through both the oblique hole 331 and the vertical hole 101. The connecting shaft 5 not only serves as a transmission mechanism but can also be used as a lifting guide structure for the adjusting member 31. After the first connecting part 11 and one of the second connecting parts 21 are inserted, rotating the adjusting knob 32 causes the locking block 33 to gradually extend laterally out of the adjusting member 31 and enter the locking groove 22, locking the first connecting body 1 and the second connecting body 2. Within the stroke range of the locking block 32, the locking block 32 can press firmly against the locking groove 22 (e.g., the bottom of the groove). Continuing to rotate the adjusting knob 32 gradually presses the second connecting body 2, eliminating the jamming gap. The pressing force can be adjusted according to the adjusting knob 32, and the whole operation is very simple. If it is necessary to select a different position, simply reverse the operation of the adjusting knob 32 to unlock, pull out the second connecting body 2, and then select another second connecting part 21 to insert into the first connecting part 11. This is easy for the user to grasp directly.
