Embodiment
Below the present invention is described in further detail.
Referring to Fig. 1, quick adjustment pull bar of the present invention comprises that bar body 1, rod head 3 be shown in Fig. 4, also comprise that sleeve 2 is shown in that Fig. 3, spring 4, upper toothed washer 5 be shown in that Fig. 5 and lower toothed packing ring 6 be shown in Fig. 6.
Referring to Fig. 2, described bar body 1 is tubular structure, for coupling sleeve 2.
Referring to Fig. 3, described sleeve 2 is tubular structure, and its one end is female thread structure, and there is fluting end, fluting and lower toothed packing ring 6 engagement connections, the quantity of fluting determines the precision of pull bar length coarse adjustment, fluting quantity be 4 and 6 respectively corresponding coarse adjustment precision be 1/4th circle and sixth circles; Its other end is fixed and is connected by cross screw bolt with bar body 1.
Refer to Fig. 4, described rod head 3 is the joint with keyway, and its bonding pad is external thread structure, for being spirally connected with internal thread of sleeve; The rod head bottom of thread, with small boss, is convenient to Compress Spring 4.
Refer to Fig. 5, described upper toothed washer 5 one side end faces are tooth-shape structure, and for realizing the fine setting of pull bar length, its degree of regulation improves with the increase of the number of teeth, the number of teeth can be 10,12 or 15, and fine setting can realize the degree of regulation of 1/10th circles, 1/12nd circle or 1/15th circle; The contrate tooth profile structure engagement of this tooth-shape structure and lower toothed packing ring 6; Its inner side is with monaural, and this monaural snaps in rod head 3 keyways; Compress Spring 4, with ears, is convenient in its outside, makes toothed washer 5 separated with lower toothed packing ring 6.For guaranteeing the intensity of packing ring, the optional structural steel of its material or stainless steel.
Refer to Fig. 6, described lower toothed packing ring 6 one side end faces are tooth-shape structure, and the number of teeth is consistent with upper toothed washer 5; Opposite side end face, with ears, snaps in the draw-in groove of sleeve 2 ends, for realizing the coarse adjustment of pull bar length.
During installation, between bar body 1 and sleeve 2, with bolt or tightening of rivet, be connected; Rod head 3 is successively through spring 4, upper toothed washer 5 and lower toothed packing ring 6; The monaural of upper toothed washer 5 inner sides snaps in the keyway of rod head 3; Last rod head 3 is connected with sleeve 2 by screw thread.
Pull bar is under use state, and spring 4 unclamps, the tooth engagement between upper toothed washer 5 and lower toothed packing ring 6, and meanwhile, the ears of lower toothed packing ring 6 other ends snap in the draw-in groove of sleeve 2 ends, and structure cannot be become flexible.
Need adjusting yoke length or dismounting during pull bar, use toothed washer 5 Compress Springs 4, make toothed washer 5 separated with lower toothed packing ring 6, locking inefficacy, sleeve 2 and rod head 3 all can independent rotation, thereby realize adjusting and the dismounting of pull bar.
It is associated with sleeve 2 that quick adjustment pull bar of the present invention is realized strut joint by upper and lower two toothed washers; Clamping stagnation by auricle and keyway and draw-in groove is realized the locking of screw thread; By Compress Spring 4, realize quick adjustment and quick-detachment; By lower toothed packing ring 6, realize coarse adjustment, coarse adjustment amount can be 1/4th circles, sixth circle; By upper toothed washer 5, realize fine setting, fine adjustment amount can reach 1/10th circles, 1/12nd circle or 1/15th circle; Therefore, the integrally-regulated precision of pull bar can reach 1/40th circle, 1/48th circle, sixtieth circle, 1/72nd circle or 1/90th circle.There is simple in structure, the advantage such as degree of regulation is high, adjusting and convenient disassembly.
