Abstract
A kind of shearing resistance countersunk head type Closely locking nut, comprise six side's twisting faces, twist into two parts groove, countersunk head type supporting surface, the groove that gets loose, internal thread, countersunk head face, closing in; Be countersunk head face under six side's twisting face vertical surfaces of this nut, be countersunk head type supporting surface under countersunk head face, countersunk head face offer three grooves that get loose, in the groove that gets loose, be provided with closing in; The angle in described six side's twisting faces and countersunk head face is provided with twists into two parts groove; The center of this nut is provided with internal thread.The utility model is easy for installation, quick, and existing instrument can realize installing, convenient disassembly; Processing technology is simple, and existing processing technique can realize batch production; Rear surface is installed and substantially there is no projection, be applicable to two sides and all require that the sandwich plate of plane is installed, and be applicable to install at body surface.
Description
Technical field
The utility model relates to a kind of shearing resistance countersunk head type Closely locking nut, particularly relates to a kind of requirement and installs the Closely locking nut that rear two sides is all planes.
Background technique
Current China aerospace flight vehicle, aerospace equipment adopt Closely locking nut to be connected with high locked bolts with other machinery anatomical connectivity mostly, and one is adopt unit shaft system interference fit to connect, and two is quick mounting.But much two-sided all requirement is that the existing part kind in plate face of plane cannot meet the demands, and all gives prominence to the several millimeter of plane after installation.The present invention can address this problem.
Model utility content
The purpose of this utility model is to overcome deficiency of the prior art, thus provides a kind of interconnection technique solved when two sides when connecting between flat panel all requires plane.And be convenient to install; During working state, this Closely locking nut has certain carrying tension, lock ability, prevents high locked bolts Automatic-falling; Thus meet the shearing resistance countersunk head type Closely locking nut of actual product anatomical connectivity demand.
A kind of shearing resistance countersunk head type Closely locking nut, comprise six side's twisting faces, twist into two parts groove, countersunk head type supporting surface, the groove that gets loose, internal thread, countersunk head face, closing in; Be countersunk head face under six side's twisting face vertical surfaces of this nut, be countersunk head type supporting surface under countersunk head face, countersunk head face offer three grooves that get loose, in the groove that gets loose, be provided with closing in; The angle in described six side's twisting faces and countersunk head face is provided with twists into two parts groove; The center of this nut is provided with internal thread.
The beneficial effect of employing technique scheme is:
1, the utility model is easy for installation, quick, and existing instrument can realize installing, convenient disassembly.
2, the utility model processing technology is simple, and existing processing technique can realize batch production.
3, the utility model installs rear surface does not have projection substantially, is applicable to two sides and all requires that the sandwich plate of plane is installed, and be applicable to install at body surface.
Accompanying drawing explanation
Fig. 1 is the utility model shearing resistance countersunk head type Closely locking nut structural representation.
In figure: 1-six side's twisting face, 2-twist into two parts groove, 3-countersunk head type supporting surface, 4-get loose groove, 5-internal thread, 6-countersunk head face, 7-close up.
Fig. 2 is schematic diagram before the utility model shearing resistance countersunk head type Closely locking nut is installed.
Fig. 3 is schematic diagram after the utility model shearing resistance countersunk head type Closely locking nut is installed.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of shearing resistance countersunk head type Closely locking nut, comprises six side's twisting faces 1, twists into two parts groove 2, countersunk head type supporting surface 3, the groove 4 that gets loose, internal thread 5, countersunk head face 6, closes up 7; Be countersunk head face 6 under six side's twisting face 1 vertical surfaces of this nut, countersunk head face is for 6 times countersunk head type supporting surface 3, countersunk head face 6 offers three grooves 4 that get loose, is provided with closing in 7 in the groove 4 that gets loose; The angle in described six side's twisting faces 1 and countersunk head face 6 is provided with twists into two parts groove 2; The center of this nut is provided with internal thread 5.
The utility model is achieved in that the supporting surface 3 of Closely locking nut body makes the form of countersunk head, countersunk head face 6 is opened three grooves 4 that get loose, close up 7 designs getting loose in groove 4, need when overhaul by three grooves 4 that get loose, Closely locking nut to be pulled down during dismounting simultaneously, installation method is identical with conventional Closely locking nut, high locked bolts is through the mounting hole of sandwich plate, the other end puts Closely locking nut, with the setting tool of six side's fixing devices and outer six side's twisting devices in band, high locked bolts is fixed, rotate six side's twisting structures of Closely locking nut, by six side's twisting structures from twist into two parts groove twist into two parts namely assemble complete.Thus realize linkage function.
Countersunk head type Closely locking nut described in the utility model by six side's twisting structures 1, twist into two parts groove 2, countersunk head type supporting surface 3, the groove 4 that gets loose, internal thread 5, countersunk head face 6, several parts such as 7 that close up form.Six side's twisting structures 1, to twist into two parts groove 2 similar to former Closely locking nut.The planar support surface of former Closely locking nut is replaced by countersunk head type supporting surface 3, increases by 4 and to get loose groove, and is arranged at closing in 7 position and gets loose in groove 4.During use, first ream countersunk head nest on sandwich plate, passes from one end by high locked bolts, is screwed on bolt by countersunk head type Closely locking nut, and as shown in Figure 2, adopt special tool to be screwed into by Closely locking nut in countersunk head nest, disconnected strength groove is twisted into two parts and can be locked, as shown in Figure 3.During dismounting, use removal tool special, deeply get loose in groove 4 by three twisting blocks, interior six side's stators stretch in the interior hexagonal hole of high locked bolts fixing, and counterrotating is namely detachable.
