Abstract
The utility model discloses a connecting bolt lock of a motor for a pumping unit. The connecting bolt lock comprises a motor base, an antitheft sleeve, a lock, a lock cylinder and a bolt. A nut is arranged on the bolt. A lock hole is formed in the end surface of the bolt. The antitheft sleeve is sheathed on the lock. The lock is sheathed on the lock cylinder. Lock pins and pin springs are arranged in the lock cylinder. The bottom of the lock cylinder is arranged in the lock hole of the bolt. The connecting bolt lock has the advantages that the structure is simple; the connecting bolt lock is convenient to use; and since the lock is arranged at one end of the bolt, the randomness of tightness operation of the bolt can be avoided, the conventional method of easily disassembling the motor is changed and the events that the motor is stolen are reduced.
Description
Technical field
The utility model relates to a kind of bolt lock, particularly a kind of used for oil extractor motor connecting bolt lock.
Background technology
At present, the power set on the oil pumper, i.e. motor, when connecting, it fixes with plain bolt, because it is the operation of bolt degree of tightness has substantivity, convenient and swift when making dismounting, but cause certain facility also for simultaneously the stolen of motor, so that motor stolen event in oil field happen occasionally.
Summary of the invention
