The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
Referring to fig. 1 to 2, an embodiment of the present application provides a plug hinge, which includes a second blade 3, a rotating shaft 2, and a first blade 1, wherein a first shaft hole 11 is provided on one side of the first blade 1, a first mounting hole 12 is provided on the other side of the first blade 1, and a first boss 13 is provided on the first blade 1; one end of the rotating shaft 2 is in interference fit with the first shaft hole 11; one side of the second blade 3 is provided with a second shaft hole 31, the other side of the second blade 3 is provided with a second mounting hole 32, the second blade 3 is provided with a second boss 33, and the other end of the rotating shaft 2 can be rotatably matched in the second shaft hole 31.
In the plug hinge provided in this embodiment, the first boss 13 and the second boss 33 are respectively disposed on the mounting surfaces of the first blade 1 and the second blade 3, and when the plug hinge is installed, the first boss 13 of the first blade 1 is embedded into the mounting surface, and the first blade 1 is further fixed onto the mounting surface by penetrating the first mounting hole 12 with the screw; similarly, the second boss 33 of the second blade 3 is embedded on the other mounting surface, and the second mounting hole 32 is penetrated by a screw to further fix the second blade 3. According to the plug hinge provided by the embodiment of the utility model, on the basis of an original screw fixing mode, the boss is arranged on the blade and is embedded into the mounting surface, so that the connection firmness between the blade and the mounting surface is greatly improved, the hinge is more accurately embedded into the mounting surface, the phenomena of offset and detachment are not easy to occur, the blade is prevented from loosening or shaking, and the stability and the service life of the hinge are reduced.
Alternatively, a groove having a shape and size identical to those of the boss (the first boss 13 or the second boss 33) may be formed in the mounting surface in advance, so that the boss of the blade is directly fitted into the groove of the mounting surface when mounted, so that the hinge is mounted.
Optionally, the first mounting hole 12 is formed on the first boss 13, and the second mounting hole 32 is formed on the second boss 33, so that the boss is fixed to the mounting surface by a screw.
Alternatively, the boss may be rectangular in shape, trapezoidal in shape, or the like.
In one embodiment, the thickness of the first boss 13 is greater than the thickness of the second boss 33. By increasing the thickness of the first boss 13, the first boss 13 is embedded deeper, and the stabilizing effect of the first boss 13 is improved.
In one embodiment, the spacing between the second mounting hole 32 and the second shaft hole 31 is smaller than the spacing between the first mounting hole 12 and the first shaft hole 11. By shortening the distance between the second mounting hole 32 and the second shaft hole 31, the distance between the fixed point (the position of the second mounting hole 32) of the second blade 3 and the stress point (the position of the rotating shaft 2) is reduced, the length of a force arm is further reduced, and the torque force applied to the screw and the second blade 3 is reduced.
In one embodiment, the cover 5 is further included, the cover 5 is disposed at the bottom end of the second shaft hole 31, and the cover 5 closes the bottom end of the second shaft hole 31. By arranging the cover 5, the dust generated by the rotation of the rotating shaft 2 is blocked from falling off, and the dust generated by the rotation is prevented from overflowing.
In one embodiment, the device further comprises a gasket 4, and the gasket 4 is sleeved on the rotating shaft 2 between the first blade 1 and the second blade 3. The spacer 4 may reduce friction between the first blade 1 and the second blade 3.
In one embodiment, the gasket 4 is a POM gasket 4, and the gasket 4 made of POM material has good wear resistance and self-lubrication, so that the service life of the gasket 4 can be prolonged and the friction between the gasket and the first blade 1/the second blade 3 can be further reduced.
