Embodiment

Please refer to Fig. 1 to Fig. 3, the better embodiment of the utility model photovoltaic module combination comprises that two stands 100, two photovoltaic modules 200 and two are for being locked in photovoltaic module 200 lockup device 10 of support 100.

Support 100 comprises a diapire 101, from the both sides of diapire 101, extend upward two relative sidewalls 102 of formation and 102 inner side is respectively inwardly and the two L shaped retaining walls 103 that extend to form downwards from two side.Between two retaining walls 103, form a gap 104.

Please refer to Fig. 4 to Fig. 6, lockup device 10 comprises a double-screw bolt 11, a pad 12, a compressing member 13, an interdiction piece 14 and a nut 15.

Double-screw bolt 11 comprises that diameter that a screw rod 111, is arranged at screw rod 111 one end is greater than the head 112 of the diameter of screw rod 111.Screw rod 111 is provided with screw thread 1111 away from one end of head 112, and this screw thread 1111 can coordinate with nut 15.

Compressing member 13 comprises two pressing plates 132 that the fixing part 131 of a U-shaped and the two ends of self-retaining portion 131 vertically stretch out and form, and the perforation 1311 of a circle is offered at the middle part of the bottom of fixing part 131.

Interdiction piece 14 comprises the two fixing plates 142 that the main board 141 of a rectangle and the both sides of autonomous agent plate 141 vertically extend to form in the same way.This main board 141 and two fixes plate 142 and jointly surrounds the containing space that without exception becomes U-shaped, and a microscler perforation 1411 is offered at the middle part of this main board 141.

During the combination of assembling photovoltaic module, the screw rod 111 of double-screw bolt 11 passes successively pad 12, the perforation 1311 of compressing member 13, the perforation 1411 of interdiction piece 14 and locks nut 15, now two of interdiction piece 14 fixes plates 142 towards the direction of nut 15.Inclination interdiction piece 14, the one end that makes interdiction piece 14 is first through the gap 104 of support 100, continue to tilt deeply until interdiction piece 14 below two retaining walls 103 of support 100 and be equipped between two side 102.Because the length of this interdiction piece 14 is slightly less than the distance between the inner side surface of two side 102 of support 100, and then interdiction piece 14 can not rotated between two side 102.Nut 15 is fastened in two of interdiction piece 14 and fixes between plate 142, and the distance between the inner side surface of two fixing plates 142 of interdiction piece 14 is slightly larger than the distance of 15 liang of parallel opposite flanks of nut, and then nut 15 can not rotated between two fixing plates 142.Again two photovoltaic modules 200 be placed on the support 100 of lockup device 10 both sides and be folded between corresponding pressing plate 132 and support 100, a relative side of two photovoltaic modules 200 is suppressed respectively two pressing plate 132 belows in compressing member 13, screws the main board 141 that double-screw bolt 11 makes interdiction piece 14 and is folded between two retaining walls 103 and nut 15 of support 100.

The nut 15 splines ground of the utility model photovoltaic module combination is contained in two fixing plates 142 of interdiction piece 14 and interdiction piece 14 splines and is contained between the two side 102 of support 100, can prevent that nut 15 from falling into the bottom of support 100, and can make nut 15 position in installation process remain unchanged, be positioned at the centre of support 100, convenient for assembly.
