Abstract
The utility model relates to a drop off-prevention rod clamp for a bearing rod of a pumping unit, which is used for pumping units for oil production in oil fields. The rod clamp has the main technology that cylindrical grooves are arranged in a left and a right clamp bodies, and springs are installed in the clamp bodies, wherein the lower parts of which are fixed by screw plugs and the upper parts of which are fixed by spring positioning pins. A folding type structure is designed on the junction of the right and left clamp bodies and is fixed by connecting pins of the clamp bodies, and cylindrical double-tooth structures with inclination angles are separately arranged on the clamp bodies and outside clamp teeth. The utility model solves the problems of bulkiness, easy rod releasing, poor safety, easy loss, easy clamp teeth releasing, etc., and the utility model can be widely used for bearing bars of pumping units for oil production in oil fields.
Description
Technical field:
The utility model relates to a kind of oil pumper bearing bar anti-drop rod card of oil field oil recovery used for oil extractor.
Background technology:
The oil pumper bearing bar card of present domestic oil field oil recovery usefulness is a square pair of shank of bolt card, can not freely glide, and can only be fixed on the oil pumper bearing bar, can not anticreep, and heaviness is easily lost, and Ka Yayi falls, shortcomings such as poor safety performance.
The utility model content:
In order to overcome the deficiency of existing oil pumper bearing bar card, the utility model provides a kind of oil pumper bearing bar anti-drop rod card, easy and simple to handle, flexible through this bar card on probation, save time, laborsaving, can automatic locking under the high-altitude application unfavorable conditions, security performance is good.
The technical scheme that its technical problem that solves the utility model adopts is, in existing bar card with the right side, left side card body connecting place is made folding paper intersection circular hole, connecting bearing pin with the card body again inserts, constituting folding paper connects, still use locking nut and tie down screw screwed connection at other end of bar card, for anti-stopping bar card comes off, make cylindric groove with angle in card body inside, the circular hole that is provided with vertically upward in card body bottom communicates with groove, spring is housed in the hole, be pressed in top on spring top with alignment pin, at circular hole bottom plug fixing spring, the plane is provided with spacing catch restriction card tooth on the card body.
The beneficial effects of the utility model are, this bar card is convenient to operation, and is laborsaving, and sensitivity can automatic locking during use, difficult drop-off, and security performance is good, and component are difficult for losing.
