Fig. 2 is that the present invention is in the structural representation under the coupled condition;
Fig. 3 is that the present invention is in the structural representation under the state of freeing;
Fig. 4 is the locating slide sleeve structural representation among the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done more specifically to describe.
As shown in Figure 1, a kind of control operating rod of the present invention is freed fast with the device that is connected and is comprised connecting screw rod 1, locating dowel pin 2, profile of tooth double-screw bolt 3, spring 4, locating slide sleeve 5 and profile of tooth swivel nut 6.One end of profile of tooth double-screw bolt 3 is screwed in the centre hole of connecting screw rod 1 one ends by screw thread, one end of the other end of profile of tooth double-screw bolt 3 and profile of tooth swivel nut 6 links together by the profile of tooth of mutual interlock, the profile of tooth of interlock can adopt square, trapezoidal or triangle, and when two profiles of tooth are engaged, the face of cylinder of two profile of tooth back periphery completes, this face of cylinder cooperates with locating slide sleeve 5 endoporus; Spring 4 is sleeved on profile of tooth double-screw bolt 3 middle parts.
Locating slide sleeve 5 is sleeved on connecting screw rod 1 and profile of tooth double-screw bolt 3 connecting bridges, profile of tooth double-screw bolt 3, profile of tooth double-screw bolt 3 and profile of tooth swivel nut 6 connecting bridges, be that locating slide sleeve 5 is nested together above-mentioned each part, and spring 4 one ends withstand on connecting screw rod 1 end face, and the other end withstands on locating slide sleeve 5 inner end surfaces.Be provided with " L " shape or " J " shape groove of sealing on the locating slide sleeve 5, " L " shape bearing of trend is consistent with locating slide sleeve 5 axis directions.Locating dowel pin 2 passes locating slide sleeve 5 " L " shape groove, and insert in connecting screw rod 1 pin-and-hole, be locating dowel pin 2 one ends and connecting screw rod 1 pin-and-hole interference fit, locating slide sleeve 5 " L " shape groove can move along locating dowel pin 2 other ends, when control operating rod is in coupled condition, locating dowel pin 2 is positioned at " L " shape top, and when control operating rod is in when freeing state, locating dowel pin 2 is positioned at outer end, " L " shape bottom.Locating dowel pin 2 is by matching with " L " shape of locating slide sleeve 5, realizes that control operating rod " frees " location with two positions of " connection ", and locating slide sleeve 5 interior bore ends have chamfering, for when entangling profile of tooth double-screw bolt 3 and profile of tooth swivel nut 6, make things convenient for centering.
Of the present invention freeing fast with connecting device is the part of control operating rod device, and as shown in Figure 2, the present invention is connected two control operating rods that are connected with needs respectively by connecting screw rod 1 and is threaded with the profile of tooth swivel nut.
Working process of the present invention is, as shown in Figure 2, when needs are freed control operating rod fast, spur locating slide sleeve 5 left with hand, until " L " shape bottom land pushes up locating dowel pin 2, then the rotational positioning sliding sleeve 5, make locating dowel pin 2 be positioned at the outer end, bottom of " L " shape groove of locating slide sleeve 5, locating dowel pin 2 is stuck in " L " shape groove, by the interaction force of locating dowel pin 2 with " L " shape groove, fix locating slide sleeve 5, this moment, profile of tooth double-screw bolt 3 and profile of tooth swivel nut 6 were all thrown off the constraint of locating slide sleeve 5, thereby free the engagement of profile of tooth double-screw bolt 3 and profile of tooth swivel nut 6, just can disconnect very easily.
When needs connect fast, with the parts of tooth mutual interlock of profile of tooth double-screw bolt 3 with profile of tooth swivel nut 6, then the rotational positioning sliding sleeve 5, make locating dowel pin 2 be positioned at " L " shape trench bottom the inner of locating slide sleeve 5, this moment, locating slide sleeve 5 entangled profile of tooth double-screw bolt 3 and profile of tooth swivel nut 6 under the effect of spring 4 automatically, like this, profile of tooth double-screw bolt 3 connects together with profile of tooth swivel nut 6.
