Abstract
The utility model relates to that a kind of frame with cascade function is fixing uses angle key, belongs to photovoltaic apparatus technical field.This angle key comprises the first Pinboard and the second Pinboard, it is characterized in that: one end of the first Pinboard is hinged on one end of the second Pinboard, and hinged hinge is provided with torsion spring; Two different angles bond order connection are connected by cascade connecting rod by angle key, and the first Pinboard and the second Pinboard are interior hollow structure, are provided with some stiffening ribs in interior hollow structure.The angle key that this angle key is made by torsion spring effect Pinboard holds power to frame retaining clip, is connected by angle key, expands with frame the operator guards of the photovoltaic cell being stationary body with this by cascade connecting rod or angle key itself with angle key.
Description
Technical field
The utility model relates to a kind of frame angle key with cascade function, belongs to photovoltaic apparatus technical field.
Background technique
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 fixed block 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 assembling difficulty is high, and assembly precision cooperation requires large.
In addition, the teeth portion of angle key generally makes intensive zigzag fashion, 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 measure 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.
Model utility content
The technical problems to be solved in the utility model is, not enough for prior art, proposes a kind of frame angle key with cascade function.
The utility model is the technological scheme solving the problems of the technologies described above proposition: a kind of frame with cascade function is fixed and used angle key, comprise the first Pinboard and the second Pinboard, one end of described first Pinboard is hinged on one end of described second Pinboard, and the hinged place of described first Pinboard and the second Pinboard is provided with the torsion spring that described first Pinboard and described second Pinboard are folded; Two different described angles bond order connection are connected by cascade connecting rod by described angle key, and described first Pinboard and the second Pinboard are interior hollow structure, are provided with some stiffening ribs in described interior hollow structure.
The improvement of technique scheme is: described cascade connecting rod two ends are provided with bolt, and the hinged hinge two ends of described angle key are provided with internal thread.
The improvement of technique scheme is: described cascade connecting rod comprises head rod and the second connecting rod, described head rod two ends are for establishing female metallic rod, described second connecting rod two ends are the metallic rod being provided with bolt, and the hinged use that the hinged hinge two ends of described angle key are provided with internal thread or described angle key is comparatively provided with screw rod in axle two ends.
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 material.
The improvement of technique scheme is: described first Pinboard and described second Pinboard entirety are wedge-like body.
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 usage 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 Pinboards are carried out hinged, and go out to arrange torsion spring at hinge, by the wall of turning round of torsion spring, Pinboard is acted on, Pinboard is naturally inwardly closed up, and under torsion spring does not stress state, the first Pinboard and the second Pinboard 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 stiffening rib in hollow structure, while ensureing structural strength, the weight of angle key is alleviated.
3) by using wedge-like body to replace generally basic first and the/the second Pinboard 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 wedge-like body 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) make angle key combination can adapt to the requirement of various nonstandard frame size by the cascade between angle key and angle key, make this angle key or angle key combination body is provided with applicability widely; In addition by the spacing between the key of cascade connecting rod assembly increase angle, the distance between frame and frame can be pulled open, pulls open the operator guards of the photovoltaic cell that frame is stationary body with this.
