[0026] The inner side of the hinge has an inner cavity to accommodate the spring lock pin, so that the spring lock pin occupies a small space on the outer side of the hinge and does not protrude too much from the outer side of the hinge, thereby avoiding scratching surrounding pedestrians or walls, etc., and the overall appearance is beautiful.

[0027] In the embodiment of the utility model, the turned-over edges are two side edges of the first plate surface and the second plate surface adjacent to each other in the hinge axis direction.

[0028] In the embodiment of the utility model, the transition corner is a connecting corner between the turned-over edges of the first and second plate surfaces and the outer end side surfaces.

[0029] The connecting corner is also formed by cutting off the sharp parts of the edges and corners of the first and second plate surfaces to finally form a transition corner, and the space surrounded by the transition corner and the hinge is used to accommodate the spring lock pin.

[0030] In the embodiment of the utility model, the transition corner is a rounded corner or a chamfered corner, but it is not limited thereto, and any other corner may be a smooth transition corner formed by cutting off the sharp parts.

[0031] In an embodiment of the utility model, the hinge includes a first chain plate 10 and a second chain plate 11 provided with a pin hole 9, the first chain plate is fixed on the outer end side of the flipped edge of the first plate surface, and the second chain plate is fixed on the outer end side of the flipped edge of the second plate surface, and the first chain plate and the second chain plate are connected via a spring lock pin.

[0032] In the embodiment of the utility model, the spring lock pin is a pressing spring lock pin, the pressing end of which is located on the inner cavity, and the pressing direction is the hinge axis of the first and second plate surfaces.

[0033] In the embodiment of the utility model, the spring lock pin includes a pin shaft 12 and a convex portion 13 fixed on the outer periphery of the pin shaft, the pin shaft is inserted into a pin hole provided on the hinge, and the edge of the pin hole is provided with a bayonet 14 for the convex portion to be axially moved and embedded or axially moved and disengaged. The bayonet and the pin hole are mutually connected.

[0034] In the embodiment of the utility model, a spring 15 sleeved on the pin is arranged between the pressing end and the inner side of the hinge.

[0035] In an embodiment of the utility model, the pin shaft is a hexagon socket bolt, the pressing end is a nut 16, the hexagon socket bolt passes through the pin hole from the outside to the inside, the nut is located in the inner cavity and is threadedly fastened with the external thread of the hexagon socket bolt, the outer diameter of the nut is larger than the inner diameter of the pin hole, and there is an axial spacing between the nut and the inner side surface of the hinge, and the spacing is greater than or equal to the stroke of the axial movement of the clamping protrusion to disengage from the clamping port.
