Abstract
The invention discloses a quickly butting structure for a fairing. The structure comprises the fairing, wherein a nut is fixed in a groove of the fairing, a support is fixed on the inner side of the fairing, and locking hooks are connected and fixed on the support through a first bolt; the locking hooks, a ball bearing, a second bolt and a nut constitute a thread reinforcing mechanism together; a bearing groove is formed in the upper end of an independently targetable cabin. The structure has the advantages as follows: 1, the fairing is inserted into the independently targetable cabin in a centered manner during butting, direct locking can be realized, radial centering is not needed, and times of repeated location are reduced; 2, the locking hooks perform locking in an inclined manner, radial centering force is produced during axial locking, and the connection is stable and reliable; 3, the contact surface of the locking hooks is large, more force can be borne, the number of the locking hooks can be reduced, and the fairing is quickly butted.
Description
Technical field
The present invention relates to a kind of trousers fast joint structure.
Background technology
Trousers is for protecting guided missile and intra-payload thereof, prevent guided missile when by atmosphere by aerodynamic force,
Aerodynamic Heating and sound such as shake at the impact of hostile environment, are the important composition parts of guided missile.At present trousers with divide that to lead docking of cabin big
Mostly it is to use vertical installation form, by large-scale hanging device, trousers is lifted, then utilize auxiliary mould to realize
Alignment, axially inserts to divide and leads cabin, then adjusts circumferential position alignment bolt hole, is finally inserted radially into and has tighted a bolt
Docking mission.But in whole docking operation, need bolt number to be mounted many, resetting often, the cooperation of installation
Spacing is little, and the workload of operator is big, and the set-up time is long.
Summary of the invention
The invention provides a kind of trousers fast joint structure.
The technical solution adopted in the present invention is: a kind of trousers fast joint structure, including trousers, nut is fixed on
Trousers groove, support is fixed on inside trousers, and locking hook is fastened on support by the first bolt；Locking bail
Pawl, ball bearing, the second screw bolt and nut collectively form screw thread force-increasing mechanism；Point leading upper end, cabin is provided with carrying groove.
Wherein, there is screwed hole inside the described ball bearing in screw thread force-increasing mechanism, by with matched screw thread
The second screw bolt and nut be installed together.
Wherein, described locking hook upper end is provided with ball bearing, and lower end coordinates with point carrying groove docking led on cabin.
The invention has the beneficial effects as follows:
1, during docking, heart insertion point is led cabin by trousers, can directly lock, it is not necessary to radial centering, decrease resetting
Number of times.
2, locking hook uses angled manner locking, produces radial centering power, stable connection, can while axial locking
Lean on.3, the contact surface of locking hook is big, can bear more power, advantageously reduces the number of locking hook, it is achieved trousers
Rapid abutting joint.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1: trousers fast joint structure sectional view；
Fig. 2: partial enlarged drawing；
Fig. 3: single trousers fast joint structure schematic diagram；
Wherein, 1 be locking hook, 2 be the first bolt, 3 be ball bearing, 4 be the second bolt, 5 be nut, 6 be support, 7 for whole
Stream cover, 8 be carrying groove, 9 for point leading cabin.
Detailed description of the invention
Below in conjunction with the accompanying drawings, parts of the present invention and mutual relation thereof are illustrated.
As shown in accompanying drawing 2,3, a kind of trousers fast joint structure includes: trousers 7, it is recessed that nut 5 is fixed on trousers 7
At groove, support 6 is fixed on inside trousers 7, and locking hook 1 is fastened on support 6 by the first bolt 2；Locking hook
1, ball bearing the 3, second bolt 4 and nut 5 collectively form screw thread force-increasing mechanism；Point lead upper end, cabin 9 and be provided with carrying groove 8.
Ball bearing 3 in above-mentioned screw thread force-increasing mechanism is internal screwed hole, by with the of matched screw thread
Two bolts 4 and nut 5 are installed together.
Above-mentioned locking hook 1 upper end is provided with ball bearing 7, and lower end coordinates with point carrying groove 8 docking led on cabin 9.
During trousers rapid abutting joint, by Large-scale Hoisting equipment trousers 7 axially aligned and point lead cabin 9, when loosening second
Drive the rotation of ball bearing 3 during the afterbody of bolt 4, then drive locking hook 1 direction inside trousers 7 to swing, at ball axle
Hold 3 when rotating to maximum angle, complete to lock hook 1 and carrying groove 8 docks cooperating, otherwise, when tightening the second bolt 4
Afterbody time then realize trousers 7 and point lead cabin 9 and separate.
Claims (3)
1. a trousers fast joint structure, it is characterised in that: include that trousers 7, nut 5 are fixed on trousers 7 groove,
Support 6 is fixed on inside trousers 7, and locking hook 1 is fastened on support 6 by the first bolt 2；Locking hook 1, ball axle
Hold the 3, second bolt 4 and nut 5 collectively forms screw thread force-increasing mechanism；Point lead upper end, cabin 9 and be provided with carrying groove 8.
A kind of trousers fast joint structure the most according to claim 1, it is characterised in that described screw thread force-increasing mechanism
In ball bearing 7 internal have screwed hole, by being installed together with the second bolt 4 of matched screw thread and nut 5.
A kind of trousers fast joint structure the most according to claim 1, it is characterised in that on described locking hook 1
End is provided with ball bearing 3, and lower end coordinates with point carrying groove 8 docking led on cabin 9.
