Abstract
The present invention provides a kind of length-adjustable rod assembly to include pull bar, also include screwed joint, locking nut, packing ring and sleeve, sleeve one end is axially connected fixing with pull bar, the sleeve other end is provided with female thread, screwed joint and the described sleeve other end screw, and namely the adjustment of screwing length realizes the adjustment of rod assembly entire length；Locking nut and packing ring are installed on the end face of the sleeve other end, with clamping screw joint.It is adjustable and lock that the program realizes rod assembly entire length on the basis of existing pull bar, and present configuration is simple and clear, easy and simple to handle, it is possible to reliablely and stablely to realize the adjustment of rod assembly entire length.
Description
Technical field
The present invention relates to a kind of length-adjustable rod assembly.
Background technology
The rod assembly length of general flight control system can not be reconciled, because connected piece exists certain deviation in actual installation, the position of connected piece need to be adjusted by pull bar physical length, for compensating the deviation of other device installation sites of manipulation system of aircraft during installation.Conventional whip length can be regulated it is thus desirable to a kind of and there is the assembly of locking function solve this installation question.
Summary of the invention
The invention provides a kind of length-adjustable rod assembly, the basis of existing pull bar realizes rod assembly entire length adjustable and lock.
The present invention provides solution below:
This length-adjustable rod assembly, including pull bar, it is characterized in that and also includes screwed joint, locking nut, packing ring and sleeve, sleeve one end is axially connected fixing with pull bar, the sleeve other end is provided with female thread, screwed joint and the described sleeve other end screw, and namely the adjustment of screwing length realizes the adjustment of rod assembly entire length；Described locking nut and packing ring are installed on the end face of the sleeve other end, with clamping screw joint.
Based on above-mentioned basic technical scheme, the present invention also does following optimization and limits and improve:
Sleeve wall is provided with inspection hole.
Locking nut and packing ring adopt electric fuse completely locked at locked position.
The medial recess of the end face of the described sleeve other end, the one side of packing ring has central protuberance, and this one side of packing ring is close to the end face of the sleeve other end.
Fixed by rivet between sleeve and pull bar.
The invention have the advantages that
Present configuration is simple and clear, easy and simple to handle, it is possible to reliablely and stablely to realize the adjustment of rod assembly entire length.

Fig. 1 is the adjustment structural representation with locking device of the present invention.
Fig. 2 is the partial sectional view (A-A) of Fig. 1.
Wherein, 1 screwed joint: 2-locking nut；3 electric fuses；4-packing ring；5-sleeve；6-rivet；7-pull bar；8-checks hole.
Detailed description of the invention
This length-adjustable rod assembly, including screwed joint, packing ring, locking nut, sleeve and pull bar etc..Wherein, adjustable end and sleeve one end rivet interlacement of pull bar are fixed, and be threaded and adopt threaded with the screwed joint end of thread inside the sleeve other end.Screwed joint and described sleeve are connected with each other and play regulatory role, the screwing length checking the described screwed joint of hole inspection on sleeve can be passed through in scope of compromise, packing ring and locking nut act the effect locking described screwed joint, and electric fuse is mainly used in safety bolt joint and locking nut；The fixing end of pull bar is generally connected with the joint equipped with bearing, and junction is typically by rivet or is welded and fixed.The adjustment of rod assembly and locking, be adjusted according to connected length, and locked by described locking nut, finally completely locked with electric fuse.
In order to ensure that screwed joint has enough screwing lengths, in the outer face of sleeve, distance sets with the inspection hole of φ 1.5～φ 1.8 equal to the screw thread distance more than 1.2 times, treats that screwed joint is adjusted to appropriate location, and locks with locking nut.
As shown in Figure 1 and Figure 2, rod assembly regulate with pull bar one end 7 and sleeve 5 one end fits in locking device after, fix with rivet, sleeve 5 band screw thread one end and screwed joint 1 adopt threaded, length adjustment can be carried out, and by the minimum screwing length checking hole control screw thread on sleeve 5；When, after length adjustment to appropriate location, packing ring 4 and locking nut 2 being installed on the screwed joint end of thread successively, one side recessed to the one side of stand-by for packing ring 4 projection and sleeve 5 is placed, then locking nut 2 is tightened, complete the assembling of adjustable end.After rod assembly has assembled, can regulate again by above-mentioned length adjustment mode according to counter-connector installation length, finally with electric fuse 3 by locked to packing ring 4 and locking nut 2.Finally realize regulating and the effect of locking of rod assembly.
