Description

A kind of wolfram steel weighted lever
Technical field
The utility model is related to tungsten steel product, more particularly to a kind of wolfram steel weighted lever.
Background technology
Wolfram steel weighted lever is the slender rod piece of rod-pumped well, connects polished rod on it, under connect the effect that oil pumping pumps up transmission power. Weighted lever of the prior art has what is connect to increase firmness using hoop generally by the way of internal whorl is fixedly connected, also Mode is fixedly connected with, but its fixation fastness is relatively low, is easily caused dropout situation in the event of when rotating in the process of running Occur, cause wolfram steel weighted lever to slide to shaft bottom, great inconvenience is brought to construction.
Utility model content
For the defect and deficiency of prior art, the purpose of this utility model is to provide a kind of simple in construction, connection jail The strong wolfram steel weighted lever of soundness.
To achieve the above object, the technical solution adopted in the utility model is:A kind of wolfram steel weighted lever, including first body of rod With second body of rod, first body of rod and second body of rod are fixedly connected, and first body of rod company is provided with below first body of rod Connect and second body of rod connection step is provided with above step, second body of rod, the lower end of first body of rod is provided with fastening Fastening is provided with above screw thread, second body of rod raised, clamp nut, the fastening spiral shell are arranged with second body of rod Mother is located at the raised lower section of fastening, and the raised protrusion width of the fastening is identical with the protrusion width of fastening thread, the fastening Nut is connected with fastening thread by internal and external threads.
Further, first body of rod connection step and second body of rod connection step is connected by internal and external threads, First body of rod connection step is raised step, and second body of rod connection step is recess step.
Further, the surface of first body of rod is provided with metal coating.
Further, the surface of second body of rod is provided with metal coating.
After said structure, the utility model has the beneficial effect that:
The utility model fixes the body of rod being sequentially connected by clamp nut, and inside is connected by internal and external threads Connect, can be connected by the direction for fastening clamp nut with first body of rod and the fastening direction of the second connection step is set to phase Anti- direction, so as to get loose, come off during avoiding use;In addition can by setting metal to be coated on body of rod surface It is effective avoid due to caused by fragility transporting, connect, carry, enter the fracture collided with during well and caused.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and specifically Embodiment, the utility model is further elaborated.It should be appreciated that embodiment described herein is only used To explain the utility model, it is not used to limit the utility model.
Referring to Fig. 1, a kind of wolfram steel weighted lever, including first body of rod 1 and second body of rod 2, the bar of first body of rod 1 and second Body 2 is fixedly connected, and the lower section of first body of rod 1 is provided with first body of rod connection step 11, first body of rod connection step 11 with First body of rod 1 passes through integrally casting shaping.The top of second body of rod 2 is provided with second body of rod connection step 21, feasible, First body of rod connection step 11 and second body of rod connection step 21 is connected by internal and external threads, and first body of rod connects Step 11 is connect for raised step, second body of rod connection step 21 is recess step.
The lower end of first body of rod 1 is provided with fastening thread 12, second body of rod 2 and is arranged with clamp nut 23, The clamp nut 23 is connected with fastening thread 12 by internal and external threads.Feasible, clamp nut 23 and fastening thread 12 To be connected screwing for the body of rod of step 11 and second connection step 21 with first body of rod in opposite direction in the direction that screws, so can be effective Prevent it from falling off in use.
The top of second body of rod 2 is provided with fastening projection 22, and fastening projection 22 can block clamp nut 23, so that Realize fastening.The clamp nut 23 is located at the lower section of fastening projection 22, protrusion width and the fastening spiral shell of the fastening projection 22 The protrusion width of line 12 is identical.Feasible, the surface of first body of rod 1 is provided with metal coating, the table of second body of rod 2 Face is provided with metal coating.In fortune caused by by that effectively can avoid due to fragility in body of rod surface setting metal coating It is defeated, connect, carry, entering the fracture caused of colliding with during well, feasible, metal, which is coated, to be coated using brittle metal.
It is described above, only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple Other modifications or equivalent substitution that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope, all should cover among right of the present utility model.
