3~16 double wedges or 3~16 concave tooth are provided with the lower spline body that upper body bottom is set, on lower body top
The upper spline body of setting is provided with 3~16 concave tooth or 3~16 double wedges；And the double wedge on lower spline body can respectively with upper flower
The corresponding mating connection of concave tooth on key body, or concave tooth on lower spline body can be corresponding with the double wedge on upper spline body respectively
It is connected.
By adopting the above-described technical solution, the utility model is compared with prior art, the utility model not only has energy
The advantages of effective anti-retaining button, but also with it is reasonable in design, simple in construction, interchangeability is good, stable work in work, easy to use
The advantages that.The utility model easily moves back the deficiency of button when effectively overcoming prior art reversion, be it is a kind of it is simple to operate just
Anti- high antitorque anti-back buckle structure, its application prospect are very extensive.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure mark for：Body, 3- adapter sleeves, the positive external pipe threads of 4-, the positive Internal Pipe Threads of 5-, 6- are left under the upper bodies of 1-, 2-
Revolve spline body, 9- upper spline bodies under external pipe thread, the left-handed Internal Pipe Threads of 7-, 8-.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but not as new to this practicality
Any restrictions of type.
A kind of positive and negative antitorque anti-back buckle structure of height, as shown in Figure 1.Including upper body 1 and lower body 2, upper body 1 with lower
Body 2 is threadedly coupled through adapter sleeve 3；The upper bottom of body 1 is provided with positive external pipe thread 4, positive external pipe thread 4 with it is just interior in adapter sleeve 3
Pipe screw thread 5 is connected；The lower top of body 2 is provided with left-handed external pipe thread 6, left-handed external pipe thread 6 with left-handed in adapter sleeve 3
Pipe screw thread 7 is connected；The upper bottom of body 1 is provided with lower spline body 8, and the lower top of body 2 is provided with upper spline body 9；Lower spline body 8 with
Upper spline body 9 is connected.
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 on lower spline body 8 and upper flower
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.
During making, also 3~16 double wedges can be set on the lower spline body 8 that the upper bottom of body 1 is set according to the needs used
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 the double wedge mating connection corresponding with the concave tooth on upper spline body 9 respectively on lower spline body 8, 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.By upper body 1, lower body 2 and adapter sleeve（3）Composition.Upper body 1 is with lower body 2 through being connected
The threaded connection of set 3.Upper body 1 and lower body 2 after connection is engaged by upper spline body 9 and lower spline body 8, prevents from inverting
When occur moving back button.
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 and lower body 2 are separated 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
Left-hand thread, upper body 1 are rotated against upper and lower screw thread with lower body 2 by limitation each other, so in rotatable connection set 3, upper
Body 1 can only relatively move 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 engages.When screwing, upper and lower positive/negative thread must be started simultaneously at and screwed.
This structure after installing, positive-torque or reaction torque are either transmitted, is all completed by end face spline, so not
In the presence of button risk is moved back, screw thread is mainly by pulling force.
