Adopt above-mentioned technical scheme, form elastic clamping through the metal shrapnel round pin of fixing at first hinge and round pin axle, the difficult fatigue inefficacy of metal shrapnel round pin elasticity, long service life to avoid the dismouting in-process metal shrapnel round pin to pop out from first hinge and drop, the structure is more reliable and more stable.
The utility model discloses a further setting: the metal elastic sheet pin comprises a fixing part and a pressing part along the length direction of the metal elastic sheet pin, the metal elastic sheet pin is arranged along the inner wall of the first hinge, and the fixing part and the pressing part form a bent shape; the fixing portion is connected with the first hinge in a riveting mode, and the pressing portion is arranged along the pin hole and is matched with the clamping groove in a clamping mode.
By adopting the further arrangement, the metal elastic sheet pin can be elastically deformed by bending, the possibility of plastic deformation of the metal elastic sheet pin is reduced, the metal elastic sheet pin keeps the elastic action in long-term use, the service life is prolonged, and the elasticity of the metal elastic sheet pin is enhanced.
The utility model discloses a further setting again: the pressing part is provided with a reinforcing rib salient point protruding from bottom to top, and the reinforcing rib salient point is close to the bending position of the pressing part and the bending position of the fixing part.
Adopt above-mentioned further setting again, strengthen the intensity and the rigidity of metal spring piece round pin, promote the elasticity effect of buckling the position, further increase of service life.
The utility model discloses a still further set up: a curling pressing cylinder is formed on the pressing part, two sides of the curling pressing cylinder curl inwards to form a long cylinder shape, and the curling pressing cylinder is clamped into the clamping groove to form clamping fit.
Adopt above-mentioned still further setting again, the crimp is pressed a section of thick bamboo and is compared in planar layering, and structural strength reinforcing is obvious, can adapt to the condition of the frequent plug of round pin axle to can increase the degree of sticising to the round pin axle.
The utility model discloses a still further set up: the metal spring plate pin is made of stainless steel 301.
By adopting the further setting, the material selection is reasonable.

Detailed Description
As shown in fig. 1-4, the hinge mechanism with a long service life comprises a first hinge 1, a second hinge and a pin shaft 2 for connecting the first hinge 1 and the second hinge, wherein the first hinge 1 comprises a pin sleeve 11, the pin shaft 2 is provided with a plurality of clamping grooves 21, the first hinge 1 is provided with a pin hole 12, the pin hole 12 extends from the main body part of the first hinge 1 to the pin sleeve 11, the first hinge 1 is fixedly provided with a metal elastic sheet pin 3, and the metal elastic sheet pin 3 extends into the pin hole 12 along the main body part of the first hinge 1 and forms a clamping fit with the clamping grooves 21. Due to the elastic effect of the metal elastic sheet pin 3, the metal elastic sheet pin 3 can be tilted or clamped into the clamping groove 21 in the process of pulling and inserting the pin shaft 2. One end of the metal elastic sheet pin 3 is always fixed on the first hinge 1, so that the metal elastic sheet pin 3 cannot be popped up and fall off.
The metal elastic sheet pin 3 includes a fixing portion 31 and a pressing portion 32 along a length direction thereof, the metal elastic sheet pin 3 is disposed along an inner wall of the first hinge 1, and a bend is provided between the fixing portion 31 and the pressing portion 32 to form a bent shape. The fixing portion 31 is riveted to the first hinge 1 by a rivet, and an end of the fixing portion 31 is inserted into the first hinge 1. The pressing portion 32 is arranged in the direction of the hole face of the pin hole 12, and the pressing portion 32 is pressed into the card slot 21 to form a snap fit.
The pressing portion 32 is provided with a rib protruding point 321 protruding from bottom to top, and the rib protruding point 321 is close to the bending position of the pressing portion 32 and the fixing portion 31. Without the bead protrusions 321, the compressed portion 32 at this position is planar, and when the compressed portion 32 is tilted, it may break at this position, and therefore, the bead protrusions 321 have the function of reinforcing the structural strength.
A curling pressing cylinder 322 is formed on the pressing part 32, two sides of the curling pressing cylinder 322 curl upwards and inwards and then are closed to form a hollow long cylinder, and the curling pressing cylinder 322 is clamped into the clamping groove 21 to form clamping fit. The shape of the curling pressing cylinder 322 is beneficial to enhancing the structural strength of the pressing part 32 which is contacted with the clamping groove 21, and the shape of the outer wall of the curling pressing cylinder 322 enables the pin shaft 2 to be inserted and pulled more smoothly.
The metal spring piece pin 3 is made of 301 elastic stainless steel.
