Description
Technical field
The present invention relates to a kind of frame angle key with cascade function, belong to photovoltaic apparatus technical field.
Background technology
It is known that photovoltaic cell and associated component thereof mostly are soft material or friable material, out of doors under harsh environments, the how normal operation of guarantee photovoltaic module.Usually take to increase the mode of mechanical strength, and we still can not meet our requirement by simply increasing the mechanical strength of photovoltaic module itself.Therefore it is contemplated that more easy mode, that is, increase frame to photovoltaic module.
And as frame, integrative-structure is not a good settling mode due to various problems such as difficulty of processing installation difficulty and molding, so we adopt the mode that many frames combine, angle key to be then usually be used as, in photovoltaic apparatus technical field, the fixture being fixed by two frames.
But, the angle key of present stage adopts integrated right-angle fixed structure often, and this makes when angle key is pressed into frame, it is necessary to carrying out organizing angle and doing three-dimensional stamping process, assembly technology is complicated, and assembly difficulty is high, and assembly precision coordinates requirement big.
In addition, the teeth portion of angle key generally makes intensive zigzag, also has and does what circular arc processed on the sharp side of teeth portion, and devises gap in the lower end of the peak back of the body, this is the space reserved for teeth portion pressurized deformation, it is possible to reduce the problem installing inconvenience in former technology to a certain extent.But this process is also faced with new problem, how to ensure a teeth portion stress Preserving problems under long-term deformed state.If this problem can not be solved; angle key in use can progressively lose its chucking power to frame; frame overall structure is loosened, final or cause that the protection structure of photovoltaic cell being stationary body with frame is fallen 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 in adapt to, and how improving angle key under the premise not affecting frame proper function is a considerable problem to the broad applicability of frame.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, it is proposed to a kind of frame with cascade function is fixed and used angle key.
The present invention solves that the technical scheme that above-mentioned technical problem proposes is: a kind of frame with cascade function is fixed and used angle key, and including the first plugboard and the second plugboard, one end of described first plugboard is hinged on one end of described second plugboard；Described angle push-to is crossed cascade connecting rod and is connected by the described angle bond order connection that two different, and described first plugboard and the second plugboard are interior hollow structure, are provided with some reinforcements in described interior hollow structure；
When being not used for fixed border when described angle key, described torsion spring is in the state of being not bound by, described first plugboard and described second plugboard and closes up under torsion spring effect.
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 female 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 setting female metallic rod, described second connecting rod two ends are the metallic rod being provided with bolt, and the hinged hinge two ends of described angle key are provided with the hinged use of female thread or described angle key and are relatively 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 materials.
The improvement of technique scheme is: described first plugboard and described second plugboard generally sphenoid.
The present invention adopts technique scheme to provide the benefit that: this angle key improves on the basis of existing technology, consider the problem keeping the good chucking power to frame and angle bond strength that in prior art, teeth portion can not be long-term, not changing for solving these problem this programme its structure is made that improvement by the basis of angle key occupation mode and obtains better effect by these improvement
1) owing to originally adopting Integral design, make angle key bigger with frame difficulty when coordinating installation, also need accurate three-dimensional punching press, and the design of one originally is split by this programme, and two plugboards are carried out hinged, and go out to arrange torsion spring at hinge, by the torsion wall 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 fixing time, installment work is simplified, and makes angle key to the more permanent chucking power of 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 first and the/the second plugboard of general essentially cuboid, angle key is physically easier to perform when being pressed into frame, make whole cooperation process of press in more smooth, the tip of sphenoid is simply plugged in frame, and abrasion deformation is less each other, alleviate the difficulty of installment work, indirectly improve efficiency of assembling.
4) angle key combination is made to be adapted to the requirement of various nonstandard frame size by the cascade between angle key and angle key so that this angle key or angle key combination body is provided with wide applicability；In addition can pass through cascade connecting rod assembly and increase the spacing between the key of angle, pull open the distance between frame and frame, pull open the protection structure of the photovoltaic cell that frame is stationary body with this.
