The clamping handle 3 and the eccentric clamping mechanism 8 are integrated into a whole.
The eccentric clamping mechanism 8 comprises a connecting plate 6 and a clamping limiting plate 7, wherein the clamping limiting plate 7 is arranged above the connecting plate 6, and the top surface of the clamping handle 3 is connected with the eccentric clamping mechanism 8 through being connected with the bottom of the connecting plate 6.
The top surface of the clamping limiting plate 7 is sequentially provided with a guide area 11, a check area 12 and a clamping area 13; the top surface of the clamping limiting plate 7 is provided with a round corner, an arc and a clamping inclined surface which are sequentially connected from inside to outside; wherein the round corners are guide areas 11; the clamping ramp is at a shorter distance from the web 6 than the arc is from the web 6. A circular arc stopping area 12; the clamping inclined surface is provided with a clamping area 13.
The bottom surface of the connecting plate 6 is connected with the clamping handle 3, and the top surface of the connecting plate 6 is connected with the bottom surface of the clamping limiting plate 7 after being inclined at an angle. So as to realize that the rotary clamping handle 3 drives the rotary clamping handle to rotate in the hollow area inside the C-shaped plate 4.
The C-shaped plate 4 comprises a top plate, a vertical plate and a bottom plate; the top plate and the bottom plate are connected to form a C-shaped plate 4; the bottom plate of the C-shaped plate 4 is connected with the front end region of the clamping handle 3 through a rivet pin shaft 5.
The C-shaped plate 4 is connected with the front end region of the clamping handle 3 through a rivet pin 5.
The top plate of the C-shaped plate 4 is provided with a supporting plate 9 and a pressing plate 10; the pressing plate 10 is connected with the bottom surface of the top plate; the supporting plate 9 is connected with the side face of the end face of the top plate; the end faces of the pressing plate 10 and the supporting plate 9 face oppositely, and the included angle between the supporting plate 9 and the end face of the top plate is 90 degrees. The top surface of the platen 10 is disposed parallel to the bottom surface of the top plate.
The C-shaped plate 4, the supporting plate 9 and the pressing plate 10 are integrally formed.
When the photovoltaic module frame is specifically used, the eccentric clamping type connecting piece is placed at the position where the photovoltaic module frame 1 and the purline 2 are required to be connected and fixed, the pressing plate 10 of the C-shaped plate 4 is pressed on the photovoltaic module frame 1, the supporting plate 9 is placed above the purline 2, the supporting plate 9 is supported on the upper surface of the purline 2, and the pressing plate 10 is responsible for pressing the photovoltaic module frame 1.
