The L-shaped leg has two installation surfaces, the bottom surface is directly connected to the stud and fixed through two nuts, and the side surface is fixed to the guide rail through a D-shaped clamp. However, the L-shaped leg has a large volume and high cost, and one type of L-shaped leg can only be matched with one size of stud, which has low versatility. SUMMARY

[0003] The utility model provides a connecting piece for connecting stud and photovoltaic support guide rail, which has simple structure, low cost and high versatility.

[0004] To solve the above technical problems, the utility model provides a connecting piece for connecting stud and photovoltaic support guide rail, which comprises a connecting piece body and a push-up piece.

[0005] At least two accommodating grooves are arranged on one side of the connecting piece body facing the support along the width direction, and the side of the accommodating groove facing the support is a first opening surface. The stud is inserted into the accommodating groove, so that the part of the stud exposed outside the side surface of the connecting piece through the first opening surface.

[0006] A clamping block is arranged between the two adjacent accommodating grooves on the side of the connecting piece body facing the support. The guide rail has an accommodating cavity for placing the clamping block, and the side of the accommodating cavity facing the connecting piece is a second opening surface.

[0007] One end of the push-up piece is exposed on the side of the connecting piece body away from the guide rail, and the other end is connected to the clamping block after passing through the connecting piece. The push-up piece is used to drive the connecting piece body and the clamping block to move towards each other under the action of external force, so that the connecting piece body and the clamping block clamp the guide rail, and the part of the stud exposed outside the side surface of the connecting piece body is in abutment with the side surface of the guide rail.

[0008] In some embodiments, when the connecting piece body and the clamping block clamp the guide rail, the clamping block and the side wall of the second opening surface are limitedly matched in the direction of the clamping block leaving the accommodating cavity.

[0009] In some embodiments, the sidewall of the second opening surface is outwardly convex to form a limiting protrusion towards the direction of the cavity bottom.

[0010] In some embodiments, the card block is provided with a limiting groove on the side facing the second opening surface, which cooperates with the limiting protrusion.

[0011] In some embodiments, the end surface of the push piece is provided with an internal hexagonal screw hole for external tools.

[0012] In some embodiments, the side surface of the guide rail is provided with a wavy protrusion corresponding to the part of the stud exposed outside the side surface of the connecting piece body.

[0013] The utility model also provides a photovoltaic system comprising a photovoltaic support guide rail and the connecting piece, and the connecting piece is used for fixing and connecting the photovoltaic support guide rail and the roof of a house.

[0014] In some embodiments, the stud passes through the roof of a house and is fixed by a nut.

[0015] Compared with the prior art, the utility model has the beneficial effects that by setting the push piece and the connecting piece body capable of accommodating the stud, the stud is directly pressed on the side surface of the guide rail by the pushing of the push piece, and is fixed by the pre-tightening force, thereby simplifying the L-shaped foot structure and reducing the cost; and the design of the double accommodating grooves can simultaneously accommodate two types of studs, thereby greatly increasing the universality of the part.

[0023] Refer to Figures 1-4 The embodiment provides a connecting piece for connecting a double-headed screw and a photovoltaic support rail, which is used for fixing and connecting a photovoltaic support rail 4 and a house roof, and comprises a connecting piece body 1 and a pushing piece 2.

[0024] At least two accommodating grooves 11 are arranged on the side of the connecting piece body 1 towards the support along the width direction, and the side of the accommodating groove 11 towards the support is a first opening surface; the double-headed screw 3 is inserted into the accommodating groove 11, so that the part of the double-headed screw 3 in the accommodating groove 11 is exposed outside the side of the connecting piece through the first opening surface.

[0025] The connecting piece body 1 is provided with a clamping block 5 between the two adjacent accommodating grooves 11 on the side of the connecting piece body 1 towards the support; the rail 4 is provided with an accommodating cavity 41 for placing the clamping block 5, and the side of the accommodating cavity 41 towards the connecting piece is a second opening surface.

[0026] One end of the pushing piece 2 is exposed on the side of the connecting piece body 1 away from the rail 4, and the other end is connected with the clamping block 5 after penetrating through the connecting piece; the pushing piece 2 is used for driving the connecting piece body 1 and the clamping block 5 to move towards each other under the action of external force, so that the connecting piece body 1 and the clamping block 5 clamp the rail 4, and the part of the double-headed screw 3 exposed outside the side of the connecting piece body 1 is abutted against the side of the rail 4.

[0027] In order to enable the connecting block body 1 and the guide rail 4 to be clamped and fixed together, when the connecting block body 1 and the clamping block 5 clamp the guide rail, the clamping block 5 is limitedly matched with the side wall of the second opening surface in the direction of the clamping block 5 away from the accommodating cavity 41, and specifically, the side wall of the second opening surface is outwardly protruded to form a limiting protrusion 411 towards the direction close to the cavity bottom of the accommodating cavity 41, and the side of the clamping block 5 towards the second opening surface is provided with a limiting groove 51 matched with the limiting protrusion 411.
