Problems solved by technology

[0002] In the existing pin rod locking structure, the pin rod is a straight rod. In order to fix the pin rod in the pin hole, a limit structure is generally adopted at both ends of the pin hole so that the pin rod will not come out of the pin hole. However, this structure The problem is that in order to allow the pin rod to be easily inserted into the pin hole, the diameter of the pin rod is usually set smaller than the pin hole, which causes the connection between the pin rod and the pin hole to be not stable but movable. When this structure is used In some fields that require stable locking, such as a fixed and adjustable photovoltaic bracket suitable for manual operation developed by the inventor, this structure will cause the photovoltaic panel to shake, damage the photovoltaic panel or cause the photovoltaic panel support to become unstable and damaged

Abstract

The invention discloses a locking device for a mountain photovoltaic fixed adjustable support suitable for manual operation. The device comprises a pin plate and a pin rod. The pin plate is provided with a second pin hole, and the central axis of the second pin hole intersects and is perpendicular to the central axis of a semicircular locking ring; the pin rod is matched with the second pin hole; the second pin hole is a screw hole; a first screw rod matched with the second pin hole is arranged at one end of the pin rod; the end, away from the first screw rod, of the pin rod is a conical body, and the diameter of the end, away from the first screw rod, of the conical body is larger than that of the first screw rod; and the end, away from the first screw rod, of the pin rod is fixedly connected with a regular polygon knob, and the central axis of the regular polygon knob coincides with the central axis of the pin rod. The problem that in the prior art, connection between a pin rod and a pin hole is not stable is solved.
