Polished rod deflection-regulating blowout-prevening sealing for oil pumping machine

The utility model relates to a polished rod deflection-regulating blowout-preventing sealer for a rod-pumped well, which belongs to a deflection-regulating blowout-preventing and sealing device for a well head of a pumping well. Each component of a deflection-regulating blowout-preventing assembly on the lower part of the utility model is arranged in an inner cavity formed by the surrounding of a collar clamp base and a ball shell gland, a ball head is arranged in a ball cavity formed by the surrounding of a lower ball shell and an upper ball shell and is positioned by a screw bolt. A blowout-preventing ball is arranged in the inner cavity of the ball head, a temporary sealing packing on the middle part of the utility model is arranged on the lower part of an inner cavity of a ball rod, and each component of a packing seal assembly is arranged on the middle and the parts of the inner cavity of the ball rod. The utility model has the functions of regulating the deflection of the well head, preventing the blowout of a polished rod for pumping oil which is broken and desquamated and sealing. When horizontal deflection-regulating is carried out, 32 millimeters can be reached; a deflection-regulating angle can reach 6 DEG; pressure which is resisted can reach 5MPa.
