Description

Technical Field

[0001] The utility model relates to the technical field of purlin connectors, in particular to a stable purlin connector for connecting photovoltaic frames. Background Art

[0002] The purlin is part of the photovoltaic support structure and is an important structural component that connects the photovoltaic panels and fixes them to the support body.

[0003] However, the purlins arranged in a straight line in the existing photovoltaic bracket are connected by connecting parts. Most of the connecting parts are single panels fastened by bolts, which cannot fix the purlins well, resulting in low stability of the purlin connection. Therefore, in order to strengthen the stability of the purlins after installation, some technologies have proposed relevant technical structures to assist the installation of the purlins. For example, there is a utility model patent with a publication number of CN219420642U, which proposes a purlin connecting part, in which an outer connecting part with a U-shaped structure is arranged on the outer side of the connection between the two purlins, and an inner connecting part with a rectangular structure is arranged on the inner side of the connection between the two purlins, so that the outer side and the inner side of the connection between the two purlins can be connected and supported at the same time, and then the four can be stably fixed together with bolts and nuts.

[0004] From the above disclosed technical contents, theoretically speaking, the implementation of the relevant technical structure is conducive to the installation of purlins. However, according to the description in the above disclosed technical contents, the purlins, external connecting parts and internal connecting parts are connected by the first bolt and the second bolt. At this time, the purlins, external connecting parts and internal connecting parts will be provided with threaded holes for facilitating the installation of the first bolt and the second bolt. At this time, when the first bolt and the second bolt are connected, the staff are required to align the corresponding threaded holes on the purlins, external connecting parts and internal connecting parts. The bolts can only be inserted after the threaded holes are aligned, which will increase the alignment steps of the threaded holes for the staff, resulting in a slowdown in the installation progress between the purlins, external connecting parts and internal connecting parts.

[0029] Working principle: When in use, first, install the purlin body 1 and the connector body 2, shrink the installation component 8 to the inside of the rectangular groove 15, and then insert the vertical rod 5 to the middle of the purlin body 1. At this time, the positioning rod 9 is inserted into the corresponding position of the outer wall of the purlin body 1. As the cross bar 6 continues to move inside the purlin body 1, the spring 801 rebounds to make the plug 802 rebound into the inside of the purlin body 1, so that the installation component 8 is connected to the purlin body 1, and the connection between the connector body 2 and the purlin body 1 is achieved. At this time, the rubber pad 4 is installed at the bottom of the protrusion 3 and the purlin body 1 to strengthen the stability of the connection between the protrusion 3 and the purlin body 1. Then, the No. 2 threaded rod 12 and the No. 2 nut 13 are used in combination to achieve the reinforcement of the stability of the connection between the purlin body 1 and the bottom of the connector body 2, and the No. 1 nut 11 and the No. 1 threaded rod 10 are used in combination to achieve the reinforcement of the stability of the connection between the side of the purlin body 1 and the side of the connector body 2. Finally, by pulling the elastic rope 803, the plug block 802 is driven to move into the rectangular groove 15. At this time, the spring 801 is in a compressed state, so that the plug block 802 is separated from the purlin body 1, and the vertical rod 5 can be taken out from the inside of the purlin body 1, so that the purlin body 1 and the connector body 2 can be separated.
