This first hinge bar and second hinge bar only have two spare parts, need not additionally to set up the round pin axle, and this kind of articulated mode of first hinge bar and second hinge bar can be assembled in advance in the factory in fact, also can take the job site to assemble, provides more selections, and the user operates according to actual need, improves the convenience, articulated elements convenient to use.

In the hinge part, the two outer side walls of the hinge part are respectively provided with a guide groove which is concavely arranged, the two guide grooves are symmetrically arranged, the inner ends of the guide grooves extend to the hinge hole, the outer ends of the guide grooves penetrate through the outer side walls of the hinge part, the groove bottoms of the two guide grooves are obliquely arranged, and the thickness between the inner ends of the groove bottoms of the two guide grooves is larger than the thickness between the outer ends of the groove bottoms of the two guide grooves. The guide way plays the effect of direction, and this kind of mode of setting at the guide way tank bottom plays the effect of progressively buffering adaptation, makes protruding removal that can be better and imbed the hinge hole in, prevent to damage.

In the above hinge, the distance between the two groove walls of the guide groove is the same as the aperture of the hinge hole. This kind of structure makes the guide way play better guide effect, does not have the problem of rocking when making first articulated rod and second articulated rod equipment, improves the packaging efficiency.

In the hinge part, the two opposite side walls of the protrusion are respectively provided with the guide surfaces which are obliquely arranged, the two guide surfaces are symmetrically arranged, and the flaring with the largest distance between the two guide surfaces does not face the bottom of the hinge groove. This kind of structure guarantees that articulated portion can follow the flaring embedding that the interval is the biggest between two guiding surfaces, can play the effect of progressively buffering adaptation, makes protruding removal that can be better and imbed in the hinge hole, prevents to damage.

In a hinge of the kind mentioned above, the angle between the guide surface and the wall of the hinge slot is between 5 and 10 °.

In the hinge assembly, the guide surface is parallel to the groove bottom of the corresponding guide groove. The protrusions move smoothly relative to each other, and the assembly is convenient.

In the hinge assembly, the hinge hole and the protrusion are circular. The hinge hole and the protrusion are both circular, so that the hinge element can rotate smoothly.

In the above-described hinge member, the second hinge lever has a corner rounding process of an end portion of the hinge groove. Preventing jamming and cutting the user. Compared with the prior art, the utility model provides a pair of articulated elements has following advantage:

1. the first hinge rod and the second hinge rod of the hinge piece are only provided with two parts, a pin shaft does not need to be additionally arranged, and the first hinge rod and the second hinge rod are not easy to fall off after being clamped.

2. This articulated elements can be assembled in advance at the mill, also can take the job site and assemble, provides more selections, and the user operates according to actual need, improves the convenience, articulated elements convenient to use.

3. This articulated elements cooperatees through the guide way tank bottom that the slope set up and the spigot surface that the slope set up, plays the effect of progressively buffering adaptation, makes protruding removal that can be better and imbed in the hinge hole, prevents to damage.
