The specific embodiment
As shown in Figure 1, the utility model comprises left and right two sections pull bars 1,6, and the right-hand member of left lever 1 is provided with a stage clip adjust bar 3, and the right-hand member of stage clip adjust bar 3 is provided with right spring perch 5; The left end of right pull bar 6 is provided with a left spring seat 2, and this left spring seat 2 is placed on the stage clip adjust bar 3, between left and right spring perch 2,5 stage clip 4 is set, and stage clip 4 is sheathed on the stage clip adjust bar 3.
As can be seen from Fig. 1, left lever 1 is made up of a hollow stem 12, the adjusting screw(rod) 13 that is fixed in the draw-bar seat 11 of these hollow stem 12 right-hand members and is located at hollow stem 12 other ends, and stage clip adjust bar 3 is fixed in the draw-bar seat 11 set centre holes.Right pull bar 6 is by a hollow stem 62, form with the adjusting screw(rod) 64 of being located at hollow stem 62 other ends with the sleeve 61 that hollow stem 62 left ends are affixed, sleeve 61 left ends are provided with negative thread, being placed in stage clip adjust bar 3 outer left spring seats 2 is connected with sleeve 61 by screw thread, left spring seat 2 is provided with one section flange 21, this flange 21 stretches in the set endoporus of draw-bar seat 61 right-hand members, the right spring perch 5 that is sheathed on stage clip adjust bar 3 right-hand members is by setting nut 7 location, setting nut 7 is connected with stage clip adjust bar 3 set outside threads, and can regulate its position as required, to regulate the elastic force of stage clip 4.Adjusting screw(rod) 13,63 on the left and right pull bar 1,6 links to each other with hollow stem 12,62 by the nut 14,64 that is arranged at two hollow stems, 12,62 ends respectively.
Principle of work of the present utility model is: do the time spent when pull bar is subjected to tensile force in catch gear, right pull bar 6 is subjected to tension displacement to the right, and drive and left spring seat 2 simultaneous displacements of sleeve 61 by being threaded, make stage clip 4 pressurizeds that are sheathed on the stage clip adjust bar 2, promote stage clip adjust bar 3 and reach the left lever 1 affixed to left dislocation with it, make whole pull bar that certain elongation be arranged, reliable to guarantee mechanism, locking effectively, and the size of the elastic force of pull bar can be regulated by the setting nut 7 at right spring perch 5 places, but the automatic compensation catch gear makes locking action more effective because of the gap that wearing and tearing produce.
As shown in Figure 2, the utility model is applied in the capacity of the tipping body tail board catch gear, and when dumping car conveyed goods, latch hook 8 will pin with the lock 9 of loading space tail board 15 weld togethers by the spring tension of pull bar of the present utility model and extension spring 10.Even this catch gear uses continually, also can pin tail board firmly by the automatically regulating of elastic draw bar length of the present utility model, can not occur losing efficacy because of wearing and tearing cause catch gear.
