Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples, but not as to any of the present invention
Limitation.
A kind of method of positive and negative high antitorque anti-back button of the present invention is to be carried out by upper body by adapter sleeve and lower body
During threaded connection, first produce lower spline body in the bottom of upper body respectively and produce upper spline body on the top of lower body,
And the lower spline physical efficiency of body bottom is intermeshed with the upper spline body on lower body top, while being produced on upper body
The positive external pipe thread of dextrorotation, produces left-handed external pipe thread on lower body, and produced on adapter sleeve can be with positive outer tube spiral shell
Positive Internal Pipe Thread and left-handed Internal Pipe Thread that line and left-handed external pipe thread are connected respectively；Then by the lower spline body of upper body with
The upper spline body intermeshing of body, the upper body worked good is separated with lower body along axis, and upper body is with in the process
Body is forbidden rotating against, after being separated a distance, by the positive Internal Pipe Thread in the positive external pipe thread of upper body and adapter sleeve
Alignment, while the left-handed external pipe thread on lower body top is alignd with the left-handed Internal Pipe Thread in adapter sleeve, is then rotatably connected
Set, due to Internal Pipe Thread left-hand thread each other above and below adapter sleeve, and makes body limited with lower body to rotate against, so
During rotatable connection set, upper body can only be relatively moved with lower body along axis, so be by upper body using threaded engagement power
The lower spline body of bottom is engaged in place with the upper spline body on lower body top, so that upper body is transmitting just anti-twisted with lower body
All there is the performance of high antitorque anti-back button during square；In order to ensure upper body with lower physical efficiency while being attached with adapter sleeve,
The positive external pipe thread of upper body is alignd with the positive Internal Pipe Thread in adapter sleeve, at the same by the left-handed external pipe thread on lower body top with
Left-handed Internal Pipe Thread alignment in adapter sleeve, then during rotatable connection set, should make the positive Internal Pipe Thread and upper body of adapter sleeve
The left-handed external pipe thread of positive external pipe thread and left-handed Internal Pipe Thread and lower body, which is started simultaneously at, to be screwed.
A kind of positive and negative high antitorque anti-back buckle structure of the invention built according to the above method, as shown in figure 1, the structure bag
Body 1 and lower body 2 are included, upper body 1 is threadedly coupled with lower body 2 through adapter sleeve 3；The upper bottom of body 1 is provided with positive outer tube spiral shell
Line 4, positive external pipe thread 4 is connected with the positive Internal Pipe Thread 5 in adapter sleeve 3；The lower top of body 2 is provided with left-handed external pipe thread 6,
Left-handed external pipe thread 6 is connected with the left-handed Internal Pipe Thread 7 in adapter sleeve 3；The upper bottom of body 1 is provided with lower spline body 8, lower
The top of body 2 is provided with upper spline body 9；Lower spline body 8 is connected with upper spline body 9.
During making, a double wedge or a concave tooth can be set on the lower spline body 8 that the upper bottom of body 1 is set, in lower body 2
A concave tooth or a double wedge are set on the upper spline body 9 that top is set；And enable the double wedge and upper spline body on lower spline body 8
Concave tooth on 9 is in mating connection, or the concave tooth on lower spline body 8 is connected with the double wedge on upper spline body 9.
During making, also two double wedges or two concave tooth can be set on the lower spline body 8 that the upper bottom of body 1 is set, at lower
Two concave tooth or two double wedges are set on the upper spline body 9 that the top of body 2 is set；And enable the double wedge and upper flower on lower spline body 8
Concave tooth on key body 9 is connected, or the concave tooth on lower spline body 8 is connected with the double wedge on upper spline body 9.
, can also be according to setting 3~16 double wedges on the lower spline body 8 that the upper bottom of body 1 is set the need for use during making
Or 3~16 concave tooth, and corresponding 3~16 concave tooth or 3~16 are set on the upper spline body 9 that the lower top of body 2 is set
Double wedge；And enable double wedge on lower spline body 8 is corresponding with the concave tooth on upper spline body 9 to be respectively connected, or under making
Concave tooth on spline body 8 corresponding with the double wedge on upper spline body 9 respectively can be connected.
Embodiment
This example is as shown in Figure 1.The structure of the present invention is made up of upper body 1, lower body 2 and adapter sleeve 3, and upper body 1 is with
Body 2 is threadedly coupled through adapter sleeve 3.Upper body 1 and lower body 2 after connection are stung mutually by upper spline body 9 with lower spline body 8
Close, thus can effectively prevent body 1, lower body 2 from the phenomenon for moving back button occur when transmitting positive reaction torque.
During specific installation, the lower spline body 8 of the upper bottom of body 1 and the upper spline body 9 on the lower top of body 2 can be nibbled in advance
Close, the upper body 1 worked good is separated with lower body 2 along axis, upper body 1 is forbidden occurring relatively with lower body 2 during this
Rotation.After being separated a distance, the positive external pipe thread 4 of upper body 1 is alignd with the positive Internal Pipe Thread 5 in adapter sleeve；Again will simultaneously
The left-handed external pipe thread 6 on the lower top of body 2 aligns with the left-handed Internal Pipe Thread 7 in adapter sleeve 3, then rotatable connection set 3, due to
Screw thread left-hand thread each other up and down, upper body 1 is rotated against with lower body 2 by limitation, so in rotatable connection set 3, upper
Body 1 can only be relatively moved with lower body 2 along axis, using threaded engagement power by the lower spline body 8 of the upper bottom of body 1 and lower body
The upper spline body 9 on 2 tops is engaged.When screwing, positive/negative thread must be started simultaneously at and screwed up and down.
This structure after installing, either transmits positive-torque or reaction torque, is all completed by end face spline, so not
In the presence of button risk is moved back, screw thread of the invention is mainly by pulling force.
