Description
Technical field
The utility model relates to that a kind of frame is fixing uses angle key, belongs 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.
Utility model content
The technical problems to be solved in the utility model is, not enough for prior art, and proposing a kind ofly has that the frame of inward collapsible trend is fixing uses angle key.
The utility model is the technical scheme solving the problems of the technologies described above proposition: the angle key that a kind of frame is fixed, comprise the first plugboard and the second plugboard, one end of described first plugboard is hinged on one end of described second plugboard, the hinged place of described first plugboard and the second plugboard is provided with torsion spring, the other end of described first plugboard and described second plugboard all offers through hole, and the axis of described through hole is parallel with hinge; Described first plugboard and the second plugboard are interior hollow structure, are provided with some reinforcements in described interior hollow structure, and described reinforcement will mark off multiple hollow triangular prism in described hollow structure;
When described angle key is not for fixing described frame, described torsion spring is in the state of not stressing, and described first plugboard and described second plugboard close up under torsion spring effect;
When described angle key is used for fixing described frame, will across establishing a pair semi-rigid connecting rod on the adjacent both sides of described frame, described semi-rigid link pin is connected on described frame, and the alignment pin of pin joint is located in perforate on described frame and described through hole; The close hinged end of described first plugboard and the second plugboard is provided with handle.
The improvement of technique scheme is: described first plugboard and described second plugboard entirety are clapboard, and the gradient of described clapboard is 30 °.
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 beneficial effect of the utility model employing technique scheme is: this angle key improves on the basis of existing technology, consider that maintenance that in prior art, teeth portion can not be long-term is to this problem of good chucking power of frame, on the basis not changing angle key occupation mode, improvement made to its structure for addressing this problem 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, alleviating the weight of angle key, indirectly reducing with frame the overall weight of the operator guards of the photovoltaic cell being stationary body.
3) clapboard being 30 ° by employing gradient replaces basic the first plugboard for cuboid of the prior art and/or the second plugboard, angle key is more easily operated when being pressed into frame, make whole assembling process more smooth, alleviate work difficulty, indirectly improve the efficiency of assembling.
4) in addition, also consider hinged be a kind of active state, therefore on plugboard, be provided with the through hole for wearing steady pin, and a semi-rigid connecting rod is crossed on adjacent frame, and be pinned on frame by steady pin, the stability between angle key and frame is improved with this, what adopt is semi-rigid connecting rod simultaneously, its have certain can deformation behavior, the power that two ends pin joint point applies can be born, ensure 1 with this) in torsion spring the active force of a supporting frame not relative motion can be provided when frame is closed up mutually, the resistance to overturning of the operator guards of the photovoltaic cell of stationary body is maintained with so metastable structure.This semi-rigid connecting rod is a peripheral state simultaneously, can be worse in time when damaging, therefore semi-rigid connecting rod need not being worried excessive due to deformation and the problem losing its supporting role brought, this problem can be solved by changing the semi-rigid connecting rod damaged or be about to damage in time.
