[0003] Existing photovoltaic frames that use adhesives in combination with corner codes for bonding or are assembled by bolt riveting have the problem of low adaptability in use due to the non-adjustability of the assembly. Therefore, an adjustable photovoltaic frame connection structure is proposed to provide a set of photovoltaic frame connection structures with adjustable assembly dimensions for the photovoltaic panel to meet the use of photovoltaic panels of various size specifications, and the assembly is convenient, and the fixing can be completed through simple buckles, and the operation is simple. Summary of the Utility Model

[0005] The technical solution adopted by the utility model to solve its technical problems is an adjustable photovoltaic frame connection structure, which includes a connecting piece and a frame. The connecting piece is inserted at both ends of the frame, and adjacent frames are connected through the connecting piece.

[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation mode.

[0023] In order to improve the applicable range of assembly, as Figures 1-5 shown, an adjustable photovoltaic frame connection structure described in the present utility model includes a connecting piece 1 and a frame 2. The connecting piece 1 is inserted at both ends of the frame 2, and adjacent frames 2 are connected by the connecting piece 1. Two groups of card holes 21 are respectively opened at both inner ends of the frame 2.

[0024] When in use, a set of adjustable photovoltaic frame connection structure for the photovoltaic panel is provided through the connecting piece 1 and the frame 2 to meet the use of photovoltaic panels of various size specifications, improve the applicable range of assembly, and the assembly is convenient. Fixing can be completed through simple buckles, and the operation is simple.

[0025] The present utility model further includes that the connecting piece 1 includes an L-shaped ferrule 11, a first insert block 12 and a second insert block 13. The first insert block 12 and the second insert block 13 have the same structure, and first tooth grooves 121 are arranged on both sides of the first insert block 12 and the second insert block 13.

[0026] The present utility model further includes that a first slot 111 for inserting the first insert block 12 is opened at one end inside the L-shaped ferrule 11, a second slot 112 for inserting the second insert block 13 is opened at the other end inside the first insert block 12, and second tooth grooves 113 for meshing with the first tooth grooves 121 are arranged on both sides inside the first slot 111 and the second slot 112.

[0027] The present utility model further includes that cavity grooves 122 are respectively opened on both sides of the first insert block 12 and the second insert block 13 away from the first tooth grooves 121. First convex blocks 123 and second convex blocks 124 for buckling with the card holes 21 are respectively fixed at both ends inside the cavity grooves 122, and one side of the end face of the first convex block 123 is provided with a chamfer.

[0028] When in use, through the first convex block 123 with one side of the end face provided with a chamfer, it is easier for the first insert block 12 and the second insert block 13 to be initially inserted into the cavity of the frame 2.

[0029] The utility model further includes a cavity 125 which is formed through the top of the first tooth groove 121 and communicates with the cavity groove 122, and is used to provide an elastic deformation space for the first bump 123 and the second bump 124 after being pressed.

[0030] The utility model further includes a through hole 114 which is formed at the corner of the L-shaped ferrule 11 and is used to reduce the weight.

[0031] When the utility model is in use, connectors 1 are arranged at both ends of the frame 2 to be spliced. With the assistance of the connectors 1, the splicing between the frames 2 is facilitated. During the operation, the operator first inserts the first insert block 12 and the second insert block 13 into the first slot 111 and the second slot 112 respectively according to the required assembly size between the frames. During the insertion, the first tooth groove 121 on the first insert block 12 and the second insert block 13 is inserted into the second tooth groove 113 at the required tooth position. Based on the insertion and engagement of the second tooth groove 113 and the first tooth groove 121, the first insert block 12 and the second insert block 13 are connected to the L-shaped ferrule 11 in an inserted manner to form a complete connector 1. Subsequently, one end of the connector 1 is inserted into the inner cavity of the end of the frame 2. During the insertion, the first bump 123 with a chamfer on the first insert block 12 and the second insert block 13 first enters the cavity of the frame 2. With the operator's tapping and the provision of the cavity 125, the first insert block 12 and the second insert block 13 can elastically deform based on the space provided by the cavity 125, so that the first bump 123 and the second bump 124 can first fill and enter the cavity of the frame 2. During this period, the first bump 123 can enter the cavity of the frame 2 first by virtue of the chamfer on it, and then enter the first group of clamping holes 21. With the operator's continuous tapping and pushing, the first bump 123 can leave the first group of clamping holes 21 by virtue of the chamfer on its end face and enter the second group of clamping holes 21, so that the first bump 123 and the second bump 124 move into the corresponding clamping holes 21 in sequence. The first bump 123 and the second bump 124 are clamped into the clamping holes 21 to complete the insertion connection between the connector 1 and the frame 2, and the adjacent frames 2 are assembled and connected.
