Preferably, the bottom of the placing groove is provided with a transition round angle. Prevent stress concentration and improve the strength of the placement groove.

Preferably, transition round corners are respectively arranged on two sides of one end, facing the bottom of the placement groove, of the sub-page. The strength of the end of the sub-page is improved.

Preferably, one end of the hinge connecting pin shaft of the main page is provided with a semi-cylindrical surface matched with the pin shaft. The parts fixed on the sub-page and the main page can rotate relatively.

Preferably, one end of the sub-page connecting pin shaft is provided with a semi-cylindrical surface matched with the pin shaft. The parts fixed on the main page and the sub-page can rotate relatively conveniently.

The utility model discloses there is following beneficial effect:

1. the structural strength is high; the thickness of the sub-page and the thickness of the mother page are uniform and thick, and the load is high; the sub-page is embedded into the main page, and the stress of the pin shaft is small;

2. the inner hinge is hidden and convenient to mount; the auxiliary page and the main page are correspondingly placed in place through the placing grooves and then are led into the pin shaft and fixed, and the installation is convenient.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

Examples

As shown in fig. 1 and 2, the heavy inner hinge is characterized by comprising a main leaf 1 and a sub leaf 2, wherein the main leaf 1 and the sub leaf 2 are rotatably connected through a pin shaft 3, a placing groove 11 for accommodating the sub leaf 2 is formed in the main leaf 1, the sub leaf 2 is positioned in the placing groove 11 of the main leaf 1, and the placing groove 11 is positioned in the middle of the main leaf 1. The thicknesses of the sub-page 2 and the main page 1 are both larger than the diameter of the pin shaft 3; the thickness of the sub-page 2 is 1.5 times of the diameter of the pin shaft 3, and the thickness of the main page 1 is 1.45 times of the diameter of the pin shaft 3. The main page 1 is provided with a reinforcing block 12. The reinforcing block 12 is shaped like a cuboid, and two groove wall surfaces of the vertical pin shaft 3 on the placing groove 11 are respectively attached to corresponding end surfaces on the sub-page 2. The one end of 2 pages of. As can be seen from fig. 4, the height of the reinforcing block 12 from the bottom surface of the mother page 1 is greater than the height of the bottom surface of the mounting groove from the bottom surface of the mother page 1, so that the reinforcing block 12 forms a position-limiting block structure on the side surface of the mounting groove. The intermediate position of spacing block structure is equipped with the regulation screw hole, can twist the bolt, and the secondary page or leaf can conveniently adjust the position in the resettlement groove 11 of primary page or leaf when closed through adjusting bolt's extension length to more be favorable to the use of reality. The bottom of the placing groove 11 is provided with a transition fillet. Transition fillets are respectively arranged on two sides of one end, facing the bottom of the placement groove 11, of the sub-leaf 2. One end of the main page 1 connected with the pin shaft 3 is provided with a semi-cylindrical surface matched with the pin shaft 3. One end of the sub-page 2 connected with the pin shaft 3 is also provided with a semi-cylindrical surface matched with the pin shaft 3.
