Description
Technical field
The utility model belongs to switch board hinge technical field, particularly relates to a kind of Flameproof box special hinge.
Background technology
In the manufacturing process of existing flame proof junction box and control cabinet, a lot of hinge that all can adopt is as the connection means of its case lid and casing, although current flame-proof type control cabinet has reached the technical level of certain flame-proof explosion-proof, but the parts least attracted attention often finally first gone wrong in its use procedure, namely it connects hinge.There is many reasonable parts that differs in existing flame proof junction box and control cabinet hinge used, as relatively simple for structure, assembly process is also more loaded down with trivial details, and efficiency of assembling is lower in structure design.The functional form of hinge is poor, and the anglec of rotation is little, is not easy to fitting operation, has had a strong impact on production efficiency, thus adds the expenditure of human cost.
Summary of the invention
The utility model provides a kind of anglec of rotation large for solving in known technology the technical problem that exists, and operating space is large, is convenient to wiring and has tension, and torsional strength, wear resistance are strong, corrosion-resistant, the Flameproof box special hinge of outward appearance exquisiteness.The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of Flameproof box special hinge, comprises hinge bodies, two joint pins and claw type annex;
Described hinge bodies, be an indivisible entirety, and present bending, face directly and curved surface, described facing directly is provided with positioning screw hole on body positioning screw hole and a projection and projection and positioning bolt, described curved surface is provided with two hinge vias, i.e. the first pan and the second pan;
Two described joint pins, i.e. the first joint pin and the second joint pin, insert in the first pan and the second pan respectively;
Described claw type annex, side-looking is spoon shape, and be divided into and face part and curvature portion directly, the position of the center of its curvature portion is provided with a through hole, the right and left of its curvature portion is respectively equipped with a symmetrical through hole along place, match respectively with the first joint pin and the second joint pin.
Further, the material of described hinge bodies and two joint pins is pure kirsite, and the material of described claw type annex is stainless steel.
Further, by hinge bodies and two joint pins and claw type annex with the use of afterwards, its anglec of rotation is 180 °.
The advantage that the utility model has and good effect are:
Because the utility model adopts as above technical scheme, namely a kind of Flameproof box special hinge, comprises hinge bodies, two joint pins and claw type annex; Described hinge bodies, be an indivisible entirety, and present bending, face directly and curved surface, described facing directly is provided with positioning screw hole on body positioning screw hole and a projection and projection and positioning bolt, described curved surface is provided with two hinge vias, i.e. the first pan and the second pan; Two described joint pins, i.e. the first joint pin and the second joint pin, insert in the first pan and the second pan respectively; Described claw type annex, side-looking is spoon shape, and be divided into and face part and curvature portion directly, the position of the center of its curvature portion is provided with a through hole, the right and left of its curvature portion is respectively equipped with a symmetrical through hole along place, match respectively with the first joint pin and the second joint pin.
Often additionally link is added in common connection hinge, cause the resistance to tension of hinge lower, with it unlike, in the process that reality uses, due to described hinge bodies, be an indivisible entirety, therefore described hinge bodies have stronger tension, torsional strength, and then wear resistance is strong, the overall life-span is also longer.
In addition, by hinge bodies and two joint pins and claw type annex with the use of afterwards, its anglec of rotation is 180 °.Further, the material of described hinge bodies and two joint pins is pure kirsite, and the material of described claw type annex is stainless steel, so Flameproof box special hinge corrosion resistance is strong.

Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of Flameproof box special hinge, comprises hinge bodies 1, two joint pins (2 and 3) and claw type annex 4; Described hinge bodies 1, be an indivisible entirety, and present bending, face directly and curved surface, described facing directly is provided with a body positioning screw hole 1-1 and projection 1-4 and projection positioning bolt, curved surface described in 1-5 is provided with two hinge vias, i.e. the first pan 1-2 and the second pan 1-3; Two described joint pins, i.e. the first joint pin 2 and the second joint pin 3, insert in the first pan 1-2 and the second pan 1-3 respectively; Described claw type annex 4, side-looking is spoon shape, and be divided into and face part and curvature portion directly, the position of the center of its curvature portion is provided with a through hole, the right and left of its curvature portion is respectively equipped with a symmetrical through hole along place, match respectively with the first joint pin 2 and the second joint pin 3.
Detailed description of the invention is as follows:
A kind of Flameproof box special hinge, comprises hinge bodies 1, two joint pins (2 and 3) and claw type annex 4; Described hinge bodies 1, be an indivisible entirety, and present bending, face directly and curved surface, described facing directly is provided with a body positioning screw hole 1-1 and projection 1-4 and projection positioning bolt, curved surface described in 1-5 is provided with two hinge vias, i.e. the first pan 1-2 and the second pan 1-3; Two described joint pins, i.e. the first joint pin 2 and the second joint pin 3, insert in the first pan 1-2 and the second pan 1-3 respectively; Described claw type annex 4, side-looking is spoon shape, and be divided into and face part and curvature portion directly, the position of the center of its curvature portion is provided with a through hole, the right and left of its curvature portion is respectively equipped with a symmetrical through hole along place, match respectively with the first joint pin 2 and the second joint pin 3.
