Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 1, the invention provides a kind of fixture of flat terraced tail end.
The fixture of flat terraced tail end comprises fixed part 10 and connecting portion 20.Particularly, fixed part 10 has the structure be fixed on by flat terraced tail end on equipment.Connecting portion 20 has the first link 21 and the second link 22, first link 21 is connected with fixed part 10, and the second link 22 is connected with flat terraced tail end, and the plane at connecting portion 20 place and the plane at fixed part 10 place have angle.
The design of this angle, make the fixed part 10 of the fixture of flat terraced tail end when can very firmly be arranged on equipment, the connecting portion 20 being also convenient to the fixture of flat terraced tail end is connected with flat ladder.The fixture of flat terraced tail end of the present invention, removes with installation rate fast, flat terraced tail end can be made to fixedly secure, and can not shake when operating personnel continues to use flat terraced outlet operation, cancel job personnel psychology is born, and increases work efficiency, ensure that the fail safe of operation.
As shown in Figure 1, the fixture of flat terraced tail end also comprises excessive portion 30, is connected between fixed part 10 and the first link 21.
Preferably, the first link 21 to extend and center line around connecting portion 20 rotates to fixed part 10 to form excessive portion 30 towards fixed part 10, and that is excessively portion 30, in reversing shape, has the curved surface of rotation.
As shown in Figure 1, preferably, the plane at fixed part 10 place is mutually vertical with the plane at connecting portion 20 place.On the one hand, connecting portion 20 can be connected with flat ladder very easily; On the other hand, fixed part 10 also can very firmly be connected with equipment.Turn round due to fixed part 10 and connecting portion 20 and turn 90 degrees, so the direction of the tail end of the fixture of flat terraced tail end can be changed.
Such structure, makes flat ladder better can adapt to operational environment.
