Abstract
The utility model relates to a multi-layer hinged-connection type balance weight body convenient to dismount and mount. The multi-layer hinged-connection type balance weight body convenient to dismount and mount comprises a lead screw and balancing weights arranged on the lead screw, fixed connecting mechanisms are arranged on the balancing weights, each fixed connecting mechanism comprises a hanging lug arranged at the upper end of the outer side of each balancing weight and two fixed plates arranged at the lower end of the outer side of each balancing weight, pin holes are formed in the two fixed plates of each fixed connecting mechanism, and pin shafts are arranged in the pin holes. Two connected balancing weights can be fixedly connected through the hanging lugs and the pin shafts, relative sliding cannot occur among the balancing weights, and safety is achieved.
Description
Technical field
The utility model relates to a kind of extracting device of oil, is specifically related to a kind of multilayer hinge formula easy disassembly balance weight body.
Background technique
Present pumping unit is a plurality of balancing weights of the installation on the counterweight leading screw generally,, without bindiny mechanism, when leading screw rocks, often can slide between balancing weight between balancing weight, connect insecure, very dangerous.
The model utility content
The utility model connects unstable problem for above-mentioned existing balance weight body, and a kind of multilayer hinge formula easy disassembly balance weight body is provided, and being fixedly connected with between its balancing weight not can relative sliding, very safe.
For achieving the above object, the technological scheme taked of the utility model is:
A kind of multilayer hinge formula easy disassembly balance weight body, it comprises leading screw and the balancing weight that is arranged on leading screw, is equipped with and is fixedly connected with mechanism on described balancing weight.
Describedly be fixedly connected with two fixed plates that mechanism comprises the hangers that is arranged on the balancing weight outer upper end and is arranged on lower end, the balancing weight outside, be provided with pin-and-hole on two fixed plates, be provided with bearing pin in pin-and-hole.
The utility model is provided with the connection hangers in the balancing weight outer upper end, lower end, the balancing weight outside is provided with two fixed plates, be provided with pin-and-hole on two fixed plates, be provided with bearing pin in pin-and-hole, be connected and can be fixedly connected with bearing pin by hangers between two balancing weights, can not produce relative sliding between balancing weight, very safe.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model hanger structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of multilayer hinge formula easy disassembly balance weight body, it comprises leading screw 1 and the balancing weight 2 that is arranged on leading screw 1, be provided with and be fixedly connected with mechanism on balancing weight 2, be fixedly connected with mechanism and comprise the hangers 3 that is arranged on balancing weight 2 outer upper end and two fixed plates 4 that are arranged on balancing weight 2 lower ends, the outside, be provided with pin-and-hole on two fixed plates 4, be provided with bearing pin 5 in pin-and-hole, bearing pin 5 can pass hangers 3.The pin-and-hole that bearing pin passes on another fixed plate of a pin-and-hole, lower floor's balancing weight hangers and upper strata balancing weight on the balancing weight fixed plate of upper strata is fixed together upper strata balancing weight and lower floor's balancing weight.
The utility model balancing weight can hang on the bearing pin 5 of the adjacent balancing weight lower end of its upside by the hangers 3 of balancing weight upper end, makes between adjacent balancing weight and is connected firmly, and is difficult for sliding, and is very safe.
