Description
Technical field
The invention belongs to load pull bar technology, be specifically related to a kind of quick adjustment pull bar.
Background technology
In existing aircaft configuration, conventional structure-bearing pull bar or strut all adopt common stop washer (or scotch), retainer nut and fuse triplicity to realize locking, stop washer (or scotch) inner side snaps in the keyway of rod head, the monaural in outside is held together by fuse and retainer nut, realizes the locking of screw thread.This locking mode, all need to remove fuse, and after having regulated, need again bind with fuse, process is loaded down with trivial details, can not realize quick adjustment and dismounting when regulating and dismantle.
In addition, said structure load pull bar or strut generally only have two, four or six flutings at sleeve ends, and its regulated quantity is only limitted to 1/2nd circles, 1/4th circles or 1/6th circles, and degree of regulation is less.
Summary of the invention
The object of the invention is: provide one can realize high precision and regulate and demolition and maintenance quick adjustment pull bar easily.Technical scheme of the present invention is: a kind of quick adjustment pull bar, comprise bar body (1) and rod head (3), it is characterized in that, also comprise sleeve (2), spring (4), upper toothed washer (5) and lower toothed packing ring (6), sleeve (2) one end is female thread structure, and there is fluting end; Rod head (3) bonding pad is external thread structure; Upper toothed washer (5) side end face is tooth-shape structure, and inner side is with monaural, and outside is with ears; Lower toothed packing ring (6) one side end face is tooth-shape structure, and opposite side end face is with ears; Be fastenedly connected between bar body (1) and sleeve (2); Spring (4) is placed between rod head (3) and upper toothed washer (5), upper toothed washer (5) below is lower toothed packing ring (6), both are engaged by tooth, the ears of lower toothed packing ring (6) side end face are stuck in the fluting of sleeve (2) end, the monaural of upper toothed washer (5) inner side is stuck in the keyway of rod head (3), is connected between rod head (3) with sleeve (2) by screw thread.
The mode that is fastenedly connected between described bar body (1) with sleeve (2) is that rivet interlacement or bolt are connected.
Advantage of the present invention is: quick adjustment pull bar of the present invention realizes strut joint 3 by upper and lower two toothed washers and associates with sleeve (2); The locking of screw thread is realized by the clamping stagnation of auricle and keyway and draw-in groove; By Compress Spring (4), upper and lower toothed washer is separated, realizes quick adjustment and the quick-detachment of pull bar; Realize coarse adjustment by lower toothed packing ring (6), realize fine setting by upper toothed washer (5), regulated quantity can reach 1/90th circle.Have that structure is simple, degree of regulation is high, regulate and the advantage such as convenient disassembly.

Embodiment
Below the present invention is described in further detail.
See Fig. 1, quick adjustment pull bar of the present invention comprises bar body 1, rod head 3 is shown in Fig. 4, also comprise sleeve 2 sees that Fig. 3, spring 4, upper toothed washer 5 are shown in that Fig. 5 and lower toothed packing ring 6 are shown in Fig. 6.
See Fig. 2, described bar body 1 is tubular structure, for coupling sleeve 2.
See Fig. 3, described sleeve 2 is tubular structure, and its one end is female thread structure, and there is fluting end, fluting is connected together with lower toothed packing ring 6, and 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 that 1/4th circles and 1/6th enclose; Its other end and bar body 1 are fixed by cross screw bolt and are connected.
Refer to Fig. 4, described rod head 3 is the joint of band 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 face is 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, then fine setting can realize the degree of regulation of 1/10th circles, 1/12nd circle or 1/15th circle; This tooth-shape structure engages with the contrate tooth profile structure of lower toothed packing ring 6; With monaural inside it, this monaural snaps in rod head 3 keyway; With ears outside it, be convenient to Compress Spring 4, toothed washer 5 is separated with lower toothed packing ring 6.For ensureing the intensity of packing ring, its material alternate configurations steel or stainless steel.
Refer to Fig. 6, described lower toothed packing ring 6 one side end face is 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 end, for realizing the coarse adjustment of pull bar length.
During installation, be connected with bolt or tightening of rivet between bar body 1 with sleeve 2; Rod head 3 is successively through spring 4, upper toothed washer 5 and lower toothed packing ring 6; Monaural inside upper toothed washer 5 snaps in the keyway of rod head 3; Last rod head 3 is connected with sleeve 2 by screw thread.
In a state of use, spring 4 unclamps pull bar, and upper toothed washer 5 engages with the tooth between lower toothed packing ring 6, and meanwhile, the ears of lower toothed packing ring 6 other end snap in the draw-in groove of sleeve 2 end, and structure cannot loosen.
When needing adjusting yoke length or dismounting pull bar, with toothed washer 5 Compress Spring 4, toothed washer 5 is separated, then locking inefficacy with lower toothed packing ring 6, sleeve 2 and rod head 3 all can independently rotate, thus realize adjustment and the dismounting of pull bar.
Quick adjustment pull bar of the present invention realizes strut joint by upper and lower two toothed washers and associates with sleeve 2; The locking of screw thread is realized by the clamping stagnation of auricle and keyway and draw-in groove; Quick adjustment and quick-detachment is realized by Compress Spring 4; Realize coarse adjustment by lower toothed packing ring 6, coarse adjustment amount can be 1/4th circles, 1/6th circles; Realize fine setting by upper toothed washer 5, 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.Have that structure is simple, degree of regulation is high, regulate and the advantage such as convenient disassembly.
