[0037] like Figure 1 , 4 As shown, a hinge includes

[0038] A first hinge seat 1, wherein the first hinge seat 1 comprises a first hinge portion 11 and a first mounting portion 12, wherein the first mounting portion 12 is used to connect with a door body of an opening and closing device;

[0039] A second hinged seat 2, the second hinged seat 2 comprises a second hinged portion 21 and a second mounting portion 22, the second hinged portion 21 is rotatably connected to the first hinged portion 11, and the second mounting portion 22 is used to be connected to the box body of the opening and closing device;

[0040] The first hinged portion 11 and the first mounting portion 12 are made of different materials, and / or the second hinged portion 21 and the second mounting portion 22 are made of different materials.

[0041] Since different parts of the hinge are provided with different materials, the strength of the hinge can meet different usage requirements through the combination of different materials.

[0042] Embodiment 1

[0043] The first hinge portion 11 and the first mounting portion 12 are made of different materials, and the second hinge portion 21 and the second mounting portion 22 are made of different materials.

[0044] Furthermore, the first hinge part 11 and the second hinge part 21 are made of plastics by injection molding, and the plastics are specifically polyoxymethylene. Polyoxymethylene (POM) is an engineering plastic with excellent performance. POM has the hardness, strength and rigidity similar to metals, has good self-lubrication, good fatigue resistance and rich elasticity in a wide range of temperature and humidity, and has good chemical resistance and low cost.

[0045] Furthermore, the first mounting portion 12 and the second mounting portion 22 are made of metal and are formed by stamping, and the metal is specifically iron, aluminum alloy or zinc alloy. Among them, aluminum alloy has good lightness and corrosion resistance, and iron has higher strength than aluminum alloy and relatively low cost.

[0046] In the case where the first mounting portion 12 and the second mounting portion 22 are made of metal, the surface of the first mounting portion 12 and the surface of the second mounting portion 22 are covered with plastic parts. The plastic parts are plastic buckles, which can provide aesthetics.

[0047] See also Figure 2 , 3 Further, the end of the first hinged part 11 is provided with a first boss 111, the cross section of the first boss 111 is non-circular, specifically, the first boss 111 is a regular polygon (such as a regular hexagon), the end of the first mounting part 12 is provided with a laterally extending first connecting member 121, the first connecting member 121 is provided with a first groove 122, the shape of the first groove 122 is adapted to the shape of the first boss 111 (such as a regular hexagon), the first groove 122 is engaged with the first boss 111, so that the first mounting part 12 is located on one side of the first hinged part 11. After the first hinged seat 1 and the second hinged seat 2 are assembled by the connecting shaft 3 and the fastener, the first mounting part 12 and the first hinged part 11 can be relatively fixed by the limiting fit between the first boss 111 and the first groove 122, so that the two can rotate synchronously.

[0048] Furthermore, a first connection groove is provided on one side of the first hinged portion 11, and a first connection edge is provided on one side of the first mounting portion 12, and the first connection edge is inserted into the first connection groove, so that the connection between the first hinged portion 11 and the first mounting portion 12 is more secure.

[0049] See also Figure 5 , 6 Further, the end of the second hinged portion 21 is provided with a second boss 211, the cross section of the second boss 211 is non-circular, specifically, the second boss 211 is a regular polygon (such as a regular hexagon), the end of the second mounting portion 22 is provided with a second connecting member 221 extending laterally, the second connecting member 221 is provided with a second groove 222, the shape of the second groove 222 is adapted to the shape of the second boss 211 (such as a regular hexagon), the second groove 222 is engaged with the second boss 211, so that the second mounting portion 22 is located on one side of the second hinged portion 21. After the second hinged seat 2 and the second hinged seat 2 are assembled by the connecting shaft 3 and the fastener, the second mounting portion 22 and the second hinged seat 2 can be relatively fixed by the limiting fit between the second boss 211 and the second groove 222, so that the two can rotate synchronously.

[0050] Furthermore, a second connection groove 212 is provided on one side of the second hinged portion 21, and a second connection edge 223 is provided on one side of the second mounting portion 22, and the second connection edge 223 is inserted into the second connection groove 212. Thus, the connection between the second hinged portion 21 and the second mounting portion 22 is more secure.

[0051] Furthermore, the second hinged portion 21 is provided with a reinforcement hole 213, and the reinforcement hole 213 is connected to the reinforcement protrusion on the box body of the opening and closing device. Through the cooperation between the reinforcement hole 213 and the reinforcement protrusion, the connection strength between the second hinge seat 2 and the box body can be further strengthened. In this way, when the opening and closing device is opened, the protrusion of the box body can limit the second hinge seat 2 through the reinforcement hole 213, so that the hinge will no longer tilt backward after being stressed, achieving an anti-tilt effect, making the hinge structure stable and reliable and will not loosen.

[0052] Among them, an opening and closing device comprises: a box body having a box opening, a recessed portion being arranged on the box body, and the reinforcing protrusion being arranged in the recessed portion; a door body, the door body being hinged at the box opening of the box body by a hinge as described in any one of the above items, the first hinged portion 11 and the second hinged portion 21 being installed in the recessed portion, and the reinforcing hole 213 being butted against the reinforcing protrusion. In this way, the protruding size and occupied space of the hinge can be reduced, and it is convenient for transportation, placement and use.

[0054] The first hinge part 11 and the first mounting part 12 are made of different materials, for example, the first hinge part 11 is plastic and the first mounting part 12 is metal. The second hinge part 21 and the second mounting part 22 are made of the same material, for example, both are plastic. The other structures of the hinge of this embodiment can adopt the same scheme as the first embodiment.
