Description

Technical Field

[0001] The utility model belongs to the technical field of solar panel installation tools, and particularly relates to a barb spanner for fixing a pressure block nut. Background Art

[0002] Photovoltaic components such as photovoltaic panels, when the photovoltaic panels are fixedly installed on the bracket, there is a gap between adjacent photovoltaic panels, and the adjacent photovoltaic panels are connected by a connector, which is fixed to the bracket below it by a hexagon socket bolt and nut assembly. When locking the hexagon socket bolt and nut assembly, the hexagon socket bolt is usually located on the connector, and the nut is located on the bracket. When the nut is tightened, the hexagon socket bolt will rotate synchronously with it. Therefore, the hexagon socket bolt must be fixed so that it cannot rotate before the nut can be tightened. However, the gap between adjacent photovoltaic panels is narrow. When the hexagon socket wrench is inserted into the hexagonal hole of the hexagon socket bolt above, the hexagon socket wrench needs to be fixed. The gap between adjacent photovoltaic panels is narrow and it is not easy for hands to pass through. Therefore, only two people can work, one standing on the photovoltaic panel to fix the hexagon socket bolt with a hexagonal wrench, and the other standing under the photovoltaic panel to tighten the nut, which is inconvenient.

[0003] To this end, a special hexagonal wrench for the middle pressure block of a photovoltaic module with the announcement number "CN217345267U" includes an L-shaped hexagonal wrench body, the handheld end of the hexagonal wrench body with a locking function is plugged into a fixed part, the fixed part includes a crossbar and a vertical bar, the end of the crossbar is fixedly connected to the top of the vertical bar, and the front end of the crossbar has a jack for inserting the handheld end of the hexagonal wrench body. The crossbar and the vertical bar are both made of pipes. It has a simple structure and is easy to use.

[0004] However, for the special hexagonal wrench for the pressure block in the above-mentioned photovoltaic module, although the hexagonal wrench body is fixed in the socket, and then the hexagonal wrench body is inserted into the countersunk hole of the hexagonal bolt to prevent it from rotating, and then the nut can be tightened, there are still the following obvious defects during use: however, the pressure block in the installation of the photovoltaic module is U-shaped, and the nut passes through the inside of the U-shape. When the wrench is used to lock the pressure block at the bottom of the photovoltaic module, the wrench may not be able to align with the hexagonal groove in the hexagonal bolt for locking during the locking process due to the personnel locking at the bottom of the photovoltaic module, which will affect the progress of the installation of the photovoltaic module.

[0011] Preferably, the bottom surface of one end of the inverted U-wrench rod is provided with a disassembly and assembly groove with an inner hexagon, and a magnetic fixing block is embedded in the inner top of the disassembly and assembly groove, which is conducive to the magnetic connection with the magnetic bit, and is conducive to the precise docking and combination of the inverted U-wrench rod and the magnetic bit during locking, avoiding the phenomenon of being unable to align with the bolt.

[0012] Preferably, an auxiliary wrench rod is laterally arranged at the bottom of the adjusting wrench rod to facilitate pulling the wrench, and anti-slip sleeves are sleeved on the surfaces of both ends of the auxiliary wrench rod, which is conducive to pulling the inverted U wrench rod to tighten the screw and avoid hand slippage.
