Description
Technical field
The utility model relates to a kind of adjusting screw rod for engineering machinery.
Background technique
In engineering is produced, commonly use screw rod, but in production process, often can need to use the screw rod of different length, can change the screw rod of different size, not only make production process waste time and energy, also increased cost of production.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, and a kind of compact structure, ingenious is provided, and practical function can need to regulate the adjusting screw rod of required specification according to difference.
The purpose of this utility model is achieved through the following technical solutions: a kind of adjusting screw rod, adjusting screw rod comprises adjustable lever, in adjustable lever, there is center cavity, adjustable lever two ends are respectively equipped with the first tapped hole and the second tapped hole, the first tapped hole is connected with the first screw rod, on the first screw rod, one end is provided with dextrorotation outside thread, and the second tapped hole is connected with the second screw rod, and on the second screw rod, one end is provided with sinistral external thread.
Further improvement of the utility model is: adjustable lever, the first screw rod and the second screw rod are cylindrical.
Further improvement of the utility model is: the corner angle of adjustable lever are mellow and fullization all.
The utility model compared with prior art has the following advantages:
Its compact structure, ingenious, practical function, can need to regulate required specification according to difference, makes production process time saving and energy saving, has greatly improved manufacturing efficiency.
accompanying drawing explanation:
Fig. 1 is part sectioned view of the present utility model;
Number in the figure: 1-adjustable lever, 2-the first screw rod, 3-the second screw rod, 4-center cavity, 5-the first tapped hole, 6-the second tapped hole, 7-dextrorotation outside thread, 8-sinistral external thread.
embodiment:
in order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows a kind of mode of execution of the utility model adjusting screw rod, described adjusting screw rod comprises adjustable lever 1, in adjustable lever 1, there is center cavity 4, adjustable lever 1 two ends are respectively equipped with the first tapped hole 5 and the second tapped hole 6, the first tapped hole 5 is connected with the first screw rod 2, on the first screw rod 2, one end is provided with dextrorotation outside thread 7, the second tapped hole 6 is connected with the second screw rod 3, on the second screw rod 3, one end is provided with sinistral external thread 8, arranging like this facilitates both hands to regulate the first screw rod 2 and the second screw rod 3 simultaneously, adjustable lever 1, the first screw rod 2 and the second screw rod 3 are cylindrical, the corner angle of adjustable lever 1 are mellow and fullization all, can avoid corner angle to cut so in one's hands, cause danger.Such adjusting screw rod compact structure, ingenious, practical function, can need to regulate the adjusting screw rod of required specification according to difference.
