Summary of the invention
The utility model mainly provides a kind of easy installation and removal, the simple solar photovoltaic assembly fastening structure of accurate positioning; Solve existing in prior technology solar photovoltaic assembly installing/dismounting inconvenience, the technical problem of location trouble.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of solar photovoltaic assembly fastening structure, the briquetting that comprises fastening photovoltaic module, one end of described briquetting is fixed on the upper surface of photovoltaic module, the other end of described briquetting is connected with adjustable Elastic buckle by connector, the other end of described Elastic buckle is connected on the guide rail, and the upper surface of described guide rail and the lower surface of described photovoltaic module join.Pressing plate is used for photovoltaic module is fastened on the aluminium rail, and pressing plate, is being fastened on the single photovoltaic module when fastening outermost photovoltaic module, and pressing plate carries out when fastening in that the photovoltaic of centre part is set up, and pressing plate is between two photovoltaic modulies.One end of pressing plate is fixed on the photovoltaic module, and briquetting is fixed by Elastic buckle and guide rail, thereby photovoltaic module is fixed on the guide rail.Elastic buckle formula fastening means can be inserted buckle in the optional position of aluminum guide rail flanging opening, need not to install from the two ends of aluminum guide rail, thereby and the location of having realized briquetting easily, saved set-up time of assembly greatly, reduced installation cost.
As preferably, described briquetting is " T " font, the upper surface of described " T " font briquetting offers elongated slot, be provided with screwed hole at elongated slot at the middle part, vertical section of " T " font briquetting below described elongated slot is provided with fluting, and the opening direction of described fluting is opposite with the opening direction of elongated slot; Described connector is the nut that matches with screw rod that passes the screw rod of described screwed hole and be positioned at Elastic buckle, and described Elastic buckle is positioned at described fluting, and the upper surface of described Elastic buckle is provided with through hole.The extended horizontal plane of " T " font of briquetting is articulated on the upper surface of photovoltaic module, the elongated slot of briquetting upper surface is used to hold the termination of bolt, the through hole that bolt passes the upper surface of the screwed hole of briquetting and Elastic buckle stretches in the Elastic buckle in the fluting of briquetting below, the lower end of bolt is by twisting connected nut existing to fixed-site with Elastic buckle, and the fluting of briquetting below is used to hold Elastic buckle.
As preferably, described Elastic buckle is by two jig arm one-body molded being " U " font, openend at described Elastic buckle is provided with voussoir, and the distance between the outer end points of two buckles during described two voussoir fastenings is not more than the opening of described guide rail upper end.Buckle is " U " font, two voussoir spares of " U " font opening have certain distance, the voussoir opening is less than the opening on aluminium rail pressure limit, because pressure effect, to intermediate compression, when aluminium rail pressure limit arrived the buckle neck by voussoir, voussoir returned to original position under flexible effect with two voussoirs on aluminium rail pressure limit, Elastic buckle is positioned aluminium rail pressure limit goes out, accurate positioning is simple in structure.
As preferably, the inwall on two jig arm tops of described Elastic buckle is provided with projection, and the distance between the blind end of described projection and Elastic buckle is identical with the thickness of nut.Projection is used for holding nut, and nut is pushed into the location, top of projection by the space in the middle of the jig arm of Elastic buckle, nut is twisted to be connected on the bolt then, thereby with the fixed-site of Elastic buckle.
As preferably, respectively be provided with a hole on two jig arm of described Elastic buckle.Hole on the Elastic buckle jig arm is to form simultaneously when the through hole of processing Elastic buckle upper surface, is a phase perforation, and the hole that bolt can pass on the jig arm extend in the interior groove of guide rail, and also directly cross-under is fixed in the hole of jig arm.
Therefore, solar photovoltaic assembly fastening structure of the present utility model has following advantage: buckle-type fastening structure of the present utility model can insert buckle in the optional position of aluminium rail pressure limit opening, need not to install from aluminium rail two ends, thereby realized the location of briquetting extremely easily, save the time that assembly is installed greatly, reduced installation cost.

Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical scheme of utility model is described in further detail.
As shown in Figure 2, a kind of solar photovoltaic assembly fastening structure, comprise two photovoltaic modulies 5, the strip briquetting 1 of " T " font is installed between two photovoltaic modulies 5, two flanging of briquetting 1 horizontal plane are hung on the upper surface of two photovoltaic modulies 5, as shown in Figure 3, the upper surface of the horizontal plane of briquetting 1 offers elongated slot 6, offer screwed hole 7 at the center of elongated slot 6, the vertical section of briquetting 1 is positioned at the groove of photovoltaic module 5, vertical section at briquetting 1 offers fluting 8, and the opening direction of fluting 8 is towards the aluminum guide rail 2 of photovoltaic module 5 belows.In fluting 8, Elastic buckle 9 is installed, shown in Figure 4 and 5, Elastic buckle 9 is to have two jig arm one-body molded, Elastic buckle 9 is " U " font, the width of Elastic buckle 9 is identical with the width of the fluting 8 of briquetting below, the free end of two jig arm of Elastic buckle 9 respectively has a voussoir 10, and the distance when jig arm clamps between the outer end points of two voussoirs 10 is less than the size of guide rail flanging opening 14.Be provided with a projection 11 on the top of each jig arm, projection 11 is identical with the thickness of nut 4 to the distance of the inner top surface of Elastic buckle 9.Offer a through hole 13 in the upper surface of Elastic buckle 9, the central lines of through hole 13 and screwed hole 7, on the jig arm of Elastic buckle, the below of projection 11 offers two holes 15, and hole 15 is the phase perforations that form when processing through hole 13.Bolt 3 is extend in the hole 15 in the Elastic buckle 9 by the screwed hole 7 of briquetting 1 top, and nut 4 links to each other with bolt 3.
During installation, by nut with snap fit on bolt, from the top of aluminum guide rail buckle inserted the gap between the flanging of aluminum guide rail, the voussoir opening is less than the opening of aluminum guide rail flanging, because the effect of pressure, the flanging of aluminum guide rail with two voussoirs of U type open front to intermediate compression.When the flanging of aluminum guide rail arrived the buckle neck by voussoir, voussoir returned to original position under flexible effect, Elastic buckle is positioned flanging place of aluminum guide rail, tights a bolt, and by briquetting photovoltaic module is being anchored on the aluminum guide rail under the effect of bolt tension force.
Specific embodiment described herein only is that design of the present utility model is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
