Description

The two interlock switching mechanisms of three bars

Technical field

The utility model relates to the two interlock switching mechanisms of a kind of three bars, the switching mechanism that is connected between especially a kind of be parallel to each other three bar bars making axially reciprocating and the bar.

Background technique

In mechanical transmission, very general by leverage transferring power and motion, the switching mechanism that is connected between at present known be parallel to each other three bar king-rods making axially reciprocating and the bar all is that the number of teeth by change wheel or sprocket wheel realizes, this conversion has a lot of defectives, and for example complex structure manufacture cost height, transmission multiple-effect rate are low, the big layout difficulty of volume or the like.

Summary of the invention

In order to overcome the deficiency that is connected conversion regime between existing be parallel to each other three bar bars and the bar, the utility model provides a kind of three bars two interlock switching mechanisms, and this mechanism structure is simple, the efficient height, and volume is little, and is easy to operate, cheap for manufacturing cost.

The technological scheme that its technical problem that solves the utility model adopts is: comprise frame mechanism and switching mechanism; Frame mechanism comprises end cap, supporting sleeve, bolt, spring washer and nut, and end cap has two, and shape is identical, symmetry is placed in two ends, being three supporting sleeves therebetween, is bolt in the supporting sleeve, and bolt, spring washer and nut connect into fixing frame mechanism to end cap, supporting sleeve; Switching mechanism comprises bar I, bar II, bar III, connect projection, connect recessed, connecting groove, locating stud, packing ring and fixing pin, three pilot holes are arranged on the above-mentioned two end cap, 1 bar is arranged in each pilot hole, three bars in three pilot holes are parallel to each other, be respectively bar I, bar II and bar III, the connection projection is installed on the bar I, connect projection and make axially locating by locating stud on its bar and packing ring, connecting projection can only rotate on bar, be equipped with on bar II and the bar III and be connected recessed, connecting the recessed pin that is fixed is fixed on the bar, connect recessed and be provided with connecting groove, connection projection on the bar I is inserted in the connecting groove that is connected recessed on bar II and the bar III, is connected thereby form between bar and the bar; Connect projection and be provided with shifting block, shifting block has three positions, left center right, and when shifting block was moved in the left center right, the connection projection on the bar I was alternately or in being inserted into bar II simultaneously and bar III going up the connecting groove that is connected recessed, thus the conversion that is connected between realization bar and the bar; For realizing the accurate enforcement of conversion, connection projection in the switching mechanism, the location that connects recessed are to adopt axial length and the axial length correspondent equal that is connected recessed that connects projection, locating stud, packing ring, when three bars all push away or move to when leaning against the arbitrary end face of end cap, just can guarantee to connect the connecting groove of recessed of projection aligning connection, thereby realize the conversion that is connected between three bar bars and the bar.

The characteristics of the utility model maximum are to realize that the middle transmission of conversion is few, and transfer process is simple and direct, thus the efficient height; Simple in structure, processing and accuracy of manufacturing are less demanding, and it is low therefore to manufacture cost; Compact structure is small and exquisite, and it is little to take up space, and helps integral layout; Simple to operate flexible with control.
