Technical Field

[0001] The utility model relates to the technical field, in particular to a photovoltaic purlin and square tube main shaft connection structure. Background Art

[0002] Photovoltaic purlin connection is an important part of the installation of solar photovoltaic brackets. The choice of connection method and construction quality directly affect the stability and safety of the photovoltaic bracket.

[0003] The selection of photovoltaic purlin connectors is crucial to the stability and safety of the connection. Most existing connectors are U-shaped connectors, which are fixed to the purlins through bolts at the top of each end of the U-shaped connector. However, this type of U-shaped connector is cumbersome to install, and due to space limitations, it cannot be installed using power tools, resulting in low installation efficiency. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, a photovoltaic purlin and square tube main shaft connection structure is provided.

[0005] To achieve the above-mentioned purpose, the present invention is configured in a preferred embodiment to include purlins, which are staggered and abutted against the top of the square tube main axis through connecting members, and one side of the connecting member is movable and can move away from and abut against the side wall of the square tube main axis.

[0006] In a preferred embodiment of the present invention, the movable portion of the connecting member can be further configured as a hinge, and is connected to the fixed point of the purlin via a pin.

[0007] In a preferred embodiment, the present invention can be further configured as follows: an arc-shaped movable groove is formed at the movable end pin of the connector corresponding to the purlin, and the arc of the movable groove is the same as the movable amplitude of the movable end.

[0008] In a preferred embodiment of the present invention, the purlin movable groove may be further configured to be provided with a downward limiting area on one side of the main axis of the square tube.

[0009] In a preferred embodiment, the present invention can be further configured as follows: reinforcing members are provided on both side walls of the inner portion of the purlin, and are fitted with the main axis of the square tube through the reinforcing members.

[0010] In a preferred embodiment of the present invention, a recessed buckling area is provided at the bottom of the reinforcement, and the buckling area is engaged with the top of the main shaft of the square tube.

[0011] Beneficial effect: The photovoltaic purlin and square tube main shaft connection structure of the utility model is relatively convenient during the installation process, does not require special tools, and can be quickly and accurately positioned through the reinforcement slot during installation. Whether it is later maintenance and disassembly or the beginning of installation, one side can be moved and tightened through the hinge on the connecting part. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1-3 As shown, a photovoltaic purlin and square tube main shaft connection structure includes a purlin 1, which is staggered and abutted against the top of the square tube main shaft 2 through a connector 3. One side of the connector 3 is movable and can move away from and abut against the side wall of the square tube main shaft 2. During installation, one side of the connector 3 is first moved away from the side wall of the square tube main shaft 2. At this time, the connector 3 is in a relaxed state, and the purlin 1 and other components can be adjusted. When the movable side of the connector 3 abuts the square tube main shaft 2, the connector 3 as a whole is in a tightened state.

[0019] The movable part of the connecting member 3 is set as a hinge, and is connected to the fixed point of the purlin 1 through a pin. The hinge here acts as a rotation point, so that the movable end can be moved.

[0020] The pin at the movable end of the connector 3 is provided with an arc-shaped movable groove corresponding to the purlin 1. The arc of the movable groove is the same as the movable amplitude of the movable end, ensuring that the pin is not interfered with during the movement of the movable end and does not need to be removed for adjustment.

[0021] The movable groove of the purlin 1 is provided with a downward limiting area on one side of the square tube main axis 2, and the limiting area is used to limit the position to prevent the pin from moving during use.

[0022] Reinforcements 4 are fitted on both side walls of the inner portion of the purlin 1 . The reinforcements 4 fit the main axis 2 of the square tube to ensure the strength of the purlin and prevent the purlin 1 from twisting or deforming during use.

[0023] The bottom of the reinforcement 4 is provided with a recessed snap-fitting area, which is engaged with the top of the square tube main shaft 2. The snap-fitting area can facilitate precise positioning and make the reinforcement 4 and the square tube main shaft 2 fit perfectly.

[0024] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity from another entity, but do not necessarily require or imply any actual relationship or order between these entities.

[0025] The above examples are merely illustrative of the present invention and do not limit the scope of protection of the present invention. Any design that is identical or similar to the present invention falls within the scope of protection of the present invention.
