As shown in fig. 1 and 3, in some embodiments of the present application, the base plate 120 includes: a first plate 121 and a first rubber pad 122.

The first plate body 121 has a plate-like structure, and the first plate body 121 forms a main body structure of the base plate 120. The first plate 121 is fixedly connected to the bracket 110, and specifically, the first plate 121 and the bracket 110 are integrally formed, so as to ensure the connection strength of the first plate and the bracket and facilitate manufacturing. Specifically, the first plate 121 may have a metal structure to ensure structural strength of the first plate 121.

The first rubber pad 122 is fixedly attached to the surface of the first plate body 121 facing the pressing plate 130. In the embodiment of the present application, the first rubber pad 122 is fixedly attached to the top surface of the first board 121. Specifically, the first rubber pad 122 may be fixedly attached to the top surface of the first plate 121 by means of adhesion, so as to facilitate assembly; the first plate 121 may be fixed to the top surface by screws or other structures to prevent relative displacement.

The top surface of first cushion 122 forms the bottom surface in centre gripping space, in the bottom plate 120 closely laminating in the bottom surface of photovoltaic support's circumstances, because rubber structure's first cushion 122 can take place great deformation, consequently first cushion 122's top surface can form bigger area of contact with photovoltaic support's bottom surface, and because rubber structure's surface has bigger friction coefficient, consequently utilize first cushion 122 can effectively increase the frictional force between bottom plate 120 and the photovoltaic support, make fastener 150 can be more firmly fixed in the photovoltaic support.

As shown in fig. 1 and 3, in some embodiments of the present application, a first groove 123 is formed at a surface of the first plate body 121 facing the first rubber pad 122, and the first groove 123 is inclined toward a direction approaching the bracket 110. Specifically, the first groove 123 is inclined toward the left in fig. 1. The first grooves 123 may be provided in plurality, and the plurality of first grooves 123 may be spaced apart along the extending direction of the first plate body 121, i.e., the plurality of first grooves 123 may be spaced apart along the left-right direction in fig. 1.

In addition, since the directions of the first groove 123 and the first protrusion 124 are both directions close to the bracket 110, when the first plate 121 moves in the direction close to the bracket 110, the first rubber pad 122 is hooked, so that the first rubber pad 122 closely follows the first plate 121, and since the friction force between the first rubber pad 122 and the photovoltaic bracket is higher, the movement of the first plate 121 in the direction close to the bracket 110 can be effectively limited, and the stability of the position of the wire clamp 150 is further ensured.

Because the first rubber pad 122 is closely attached to the photovoltaic bracket, and a gap is formed between the adjacent second protrusions 125, the second protrusions 125 hook the protruding portions of the photovoltaic bracket at the left side of the second protrusions 125, so that the friction force between the first rubber pad 122 and the photovoltaic bracket is further improved. Of course, it should be noted that, in the present application, the width of the gap between the adjacent second protrusions 125 is much smaller than the width of the second protrusions 125, so that a sufficient contact area between the first rubber pad 122 and the photovoltaic bracket can be ensured.

The bottom surface of second cushion 132 forms the top surface in centre gripping space, under the circumstances of clamp plate 130 closely laminating in the top surface of photovoltaic support, because rubber structure's second cushion 132 can take place great deformation, consequently the bottom surface of second cushion 132 can form bigger area of contact with the top surface of photovoltaic support, and because rubber structure's surface has bigger friction coefficient, consequently utilize second cushion 132 can effectively increase the frictional force between clamp plate 130 and the photovoltaic support, make fastener 150 can be more firmly fixed in the photovoltaic support.

As shown in fig. 1 and 4, in some embodiments of the present application, the surface of the second plate 131 facing the second rubber pad 132 forms a second groove 133, and the second groove 133 is inclined toward a direction approaching the bracket 110.

At least part of the third protrusion 134 is disposed in the second groove 133. By using the third protrusion 134 and the second groove 133, the second plate 131 and the second rubber pad 132 can form a mutually abutting state in the left-right direction, and the second rubber pad 132 can be effectively prevented from sliding left and right relative to the second plate 131, so that the stability of the position of the wire clamp 150 is further ensured. In addition, since the directions of the second groove 133 and the third protrusion 134 are both directions close to the bracket 110, when the second plate 131 moves in the direction close to the bracket 110, the second rubber pad 132 is hooked, so that the second rubber pad 132 closely follows the second plate 131, and since the friction force between the second rubber pad 132 and the photovoltaic bracket is higher, the movement of the second plate 131 in the direction close to the bracket 110 can be effectively limited, and the stability of the position of the wire clamp 150 is further ensured.

Of course, it should be noted that, in the present application, the width of the gap between the adjacent fourth protrusions 135 is much smaller than the width of the fourth protrusions 135, so that a sufficient contact area between the second rubber pad 132 and the photovoltaic bracket can be ensured.

As shown in fig. 1 and 2, in some embodiments of the present application, the adjustment structure 140 includes: a screw 141 and a nut 142.

The screw 141 has a rod-like structure. Specifically, the screw 141 has a cylindrical shape. The sidewall of the screw 141 forms an external thread.

The nut 142 has a cylindrical structure. Specifically, an internal thread is formed in a hole in the middle of the nut 142, and the internal thread on the nut 142 and an external thread on the screw 141 correspond to each other, so that the screw 141 can be screwed to the nut 142, and the nut 142 can move relatively to the screw 141 on the axis of the screw 141 under the condition that the screw 141 and the nut 142 are relatively rotated.

The other end of the connecting member 144 is fixedly connected to the pressing plate 130. In the case that the screw 141 rotates relative to the nut 142, the screw 141 drives the connecting member 144 to approach or separate from the nut 142, i.e., the distance between the platen 130 and the base plate 120 can be adjusted by rotating the screw 141 relative to the nut 142 to adjust the distance between the platen 130 and the support 110.
