| description | The invention discloses a blowout prevention packing box used after a polished rod of an injection-suction type oil pumping unit is broken. The packing box mainly solves the problem that crude oil leaks when a polish rod of a pumping unit is broken and disengaged in an existing packing box. The packing box is characterized in that a round hole is formed in the side wall of the packing box pressing cap (1), the round hole is connected with a ball storage bin body (9), a rubber ball (10) is arranged in the ball storage bin body (9), the depth of the ball storage bin body (9) is larger than the diameter of the rubber ball (10), and the outer side of the ball storage bin body (9) inclines downwards. According to the blowout prevention packing box after the polish rod of the injection and suction type oil pumping unit is broken, oil gas leakage can be avoided after the polish rod of the oil pumping unit is broken and falls off, and environmental pollution and unnecessary yield loss are reduced.
