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, proposes that a kind of frame of the band groove can fixed with rim fits is fixing uses angle key.This angle key is by arranging special groove by relative with the position of frame for angle key fixing.
The utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of frame with groove is fixing uses Novel angle key, comprise the first plugboard and the second plugboard, 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 that described first plugboard and described second plugboard are folded; 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; The both sides of described first plugboard are provided with the first direction recess along described first plugboard length direction, and the both sides of described second plugboard are provided with the second direction recess along described second plugboard length direction; Described first direction recess and described second direction recess front end are provided with the endoporus for receiving flat key; The close hinged end of described first plugboard and the second plugboard is provided with handle, the first and second plugboards closed up can be separated by squeeze grip.
The improvement of technique scheme is: the described first or second direction recess is dovetail groove.
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: described angle key improves on the basis of existing technology, consider that in prior art, teeth portion can not ensure this problem of good chucking power for a long time, 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) consider that hinged is a kind of active state, therefore groove is provided with in the both sides of plugboard, this groove is to ensure that installing at angle key and rim fits is to play certain guide effect on the one hand, by the storage flat key endoporus be arranged in groove, the relative position of angle key and frame can also be fixed simultaneously, certainly this frame need offer through hole on a corresponding position, and offer one and cut the elongated slot that flat key can be made to pass through this through hole circle, the fixed axis being connected with flat key can enter groove through this elongated slot, by rotate fixed axis up knob just can by angle key and fixed axis position locked.Simultaneously due to the power acted on the first and/or second plugboard of torsion spring, make it inwardly play clamping action to frame, and do not slide relative to frame.
3) 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.
4) if groove is dovetail groove, then can by effect 2) in fixed axis drag in elongated slot and just can to realize on diverse location, by relative with frame for angle key fixing, frame coordinated with angle key carrying out on demand and adjusting.
