Abstract
The utility model relate to a kind of can the frame of horizontal cascade be fixing uses angle key, belong to photovoltaic apparatus technical field.This angle key, comprises the first plugboard and the second plugboard, a long narrow side of the first plugboard is provided with sunk key along length direction, the side relative with long narrow side is provided with keyway along length direction; One end of first plugboard is hinged on one end of the second plugboard, and the hinged place of the first plugboard and the second plugboard is provided with torsion spring; First plugboard and the second plugboard are interior hollow structure, are provided with some reinforcements in interior hollow structure.This angle key is by working the torsion spring of the effect of closing up to plugboard, angle key is made to remain lasting chucking power to frame, and coordinate by the key on the key of angle and groove the seamless link realized between the key of angle, adapt to the demand of some non-standards with this, improve the applicability of this angle key.
Description
Technical field
The utility model relate to a kind of can the frame of horizontal cascade be fixing uses angle key, belong to photovoltaic apparatus technical field.
Background technology
As everyone knows, photovoltaic cell and associated component thereof mostly are soft material or friable material, out of doors under harsh environments, and the how normal work of guarantee photovoltaic module.Normally take the mode increasing mechanical strength, and we are not still by simply increasing the mechanical strength of photovoltaic module itself to meet our requirement.Therefore we consider more easy mode, and that is exactly increase frame to photovoltaic module.
And as frame, integrative-structure due to difficulty of processing installation difficulty and the various problems such as shaping be not a good settling mode, so our mode of adopting polygon frame to combine, angle key is then usually be used as in photovoltaic apparatus technical field the fixture be fixed by two frames.
But the angle key of present stage adopts integrated right-angle fixed structure often, this makes when by angle key press-in frame, and need carry out group angle and do three-dimensional punching press process, assembly technology is complicated, and assembly difficulty is high, and assembly precision cooperation requires large.
In addition, the teeth portion of angle key generally makes intensive zigzag, also has on the sharp side of teeth portion, to do circular arc process, and devise gap in the lower end of the peak back of the body, this is the reserved space of teeth portion pressurized deformation, can reduce in former technology the problem of installing inconvenience to a certain extent.But this process is also faced with new problem, how to ensure the stress Preserving problems of teeth portion under long-term deformed state.If can not address this problem; angle key in use progressively can lose its chucking power to frame; frame overall structure is loosened, final or cause the operator guards of the photovoltaic cell taking frame as stationary body to fall apart, cause economic loss or other significant damage.
And existing angle key is often only applicable to specific frame, or standard size frame, size for some nonstandard frames is often difficult to adapt to, and under the prerequisite not affecting frame proper function, how to improve the broad applicability of angle key to frame is a considerable problem.
Utility model content
The technical problems to be solved in the utility model is, not enough for prior art, propose a kind of can the frame of horizontal cascade be fixing uses angle key.
The utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of can the frame of horizontal cascade be fixing uses angle key, comprise the first plugboard and the second plugboard, one long narrow side of described first plugboard is provided with sunk key along length direction, the side relative with described long narrow side is provided with keyway along length direction; One end of described first plugboard is hinged on one end of described second plugboard, and the hinged place of described first plugboard and the second plugboard is provided with the torsion spring for making the first plugboard and the second plugboard mutually close up; Described first plugboard and the second plugboard are interior hollow structure, are provided with some reinforcements in described interior hollow structure.
The improvement of technique scheme is: described torsion spring is made up of carbon spring steel wires.
The improvement of technique scheme is: described angle key is made up of aluminum alloy materials.
The improvement of technique scheme is: described first plugboard and described second plugboard entirety are sphenoid.
The improvement of technique scheme is: described sphenoid cross section is up wedge shape.
The improvement of technique scheme is: described sphenoid cross section is descending wedge shape.
The beneficial effect of the utility model employing technique scheme is: this angle key improves on the basis of existing technology, consider the good chucking power of maintenance to frame and the problem of angle bond strength that in prior art, teeth portion can not be long-term, on the basis not changing angle key occupation mode, improvement made to its structure for addressing these problems this programme and obtained better effect by these improvement
1) owing to originally adopting Integral design, make angle key and frame coordinate install time difficulty larger, also need accurate three-dimensional punching press, and the design of script one splits by this programme, and two plugboards are carried out hinged, and go out to arrange torsion spring at hinge, by the wall of turning round of torsion spring, plugboard is acted on, plugboard is naturally inwardly closed up, and under torsion spring does not stress state, the first plugboard and the second plugboard close up and are integrated.This make use this angle key carry out frame fix time, installment work is simplified, and makes angle key have more permanent chucking power to frame.
2) by arranging reinforcement in hollow structure, while ensureing structural strength, the weight of angle key is alleviated.
3) by using sphenoid to replace generally basic first and the/the second plugboard for cuboid, angle key is made to be easier to operation when being pressed into frame, make whole cooperation process of press in more smooth, the tip of sphenoid is easy to be inserted in frame, and wearing and tearing deformation is less each other, alleviate the difficulty of installment work, indirectly improve efficiency of assembling.
4) making horizontal cascading relief angle key group can adapt to the requirement of various nonstandard frame size by being coordinated with sunk key to install by the keyway of different angles key, making this angle key or angle key combination body is provided with applicability widely; After the mutual horizontal cascading between hour angle key, add the chucking power of angle key to frame, improve with frame the stability of the operator guards of the photovoltaic cell being stationary body.
