Abstract
The utility model relates to a kind of novel crossed fixed border angle key arranging reinforcement, belongs to photovoltaic apparatus technical field.This angle key comprises the first plugboard and the second plugboard, it is characterized in that: one end of the 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; The other end of the first plugboard and the second plugboard is equipped with the buckle at the oblong openings place for being connected to frame; First plugboard and the second plugboard are interior hollow structure, are provided with some reinforcements in interior hollow structure, and reinforcement arranged in a crossed manner making in described hollow structure forms network between the reinforcement in hollow structure.This angle key adds the chucking power of angle key to frame by torsion spring with being clasped, and makes the operator guards of the photovoltaic cell taking frame as stationary body more firm, strengthens angle bond strength simultaneously by the reinforcement of horizontally set.
Description
Technical field
The present invention relates to that a kind of frame is 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.
Utility model content
The technical problems to be solved in the utility model is, not enough for prior art, proposes a kind of novel crossed fixed border angle key arranging reinforcement.
The utility model is the technical scheme solving the problems of the technologies described above proposition: a kind of novel crossed fixed border angle key arranging reinforcement, 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 torsion spring; The other end of described first plugboard and described second plugboard is equipped with the buckle at the oblong openings place for being connected to described frame; Described first plugboard and the second plugboard are interior hollow structure, are provided with some reinforcements in described interior hollow structure, and arranged in a crossed manner the making in described hollow structure of described reinforcement forms network between the reinforcement in described hollow structure;
When described angle key is not for fixed border, described torsion spring is in the state of not stressing, and described first plugboard and described second plugboard close up under torsion spring effect.
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 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; the weight of angle key is alleviated while ensureing structural strength; simultaneously arranged in a crossed mannerly disperse stress point; avoid the outstanding damage of local pressure; affect the useful life of angle key, indirectly reduce with frame the overall weight of the operator guards of the photovoltaic cell being stationary body simultaneously.
3) in addition, also consider hinged be a kind of active state, on plugboard, be therefore provided with the buckle at the oblong openings place for being connected to described frame, to ensure that the relative position between angle key and plate does not change.
4) 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.
