Description
Technical field
It the utility model is related to a kind of anti-loose structure and checknut part.
Background technology
In existing mainshaft nut anti-loose structure, conventional anti-loose structure has pairs of anti-loose nut, adds screw thread at threaded engagement
Glue is locking, the locking nut of locking pin etc..But in the case of shock and vibration and varying load, nut pretightning force can decline, with
The increase of vibration number, the pretightning force of loss gently increases, and most causes nut to release threaded connection failure at last.And use
The shortcomings that screw thread glue bond is locking is that bolt is used only once, and is dismantled very difficult, it is necessary to which destroying screw thread pair can dismantle.
Utility model content
For overcome the deficiencies in the prior art, a purpose of the present utility model is to provide a kind of anti-loose structure, and it is anti-
Pine works well.
Another purpose of the present utility model is to provide a kind of checknut part, and it possesses good anti-loosing effect.
The purpose of this utility model adopts the following technical scheme that realization：
A kind of anti-loose structure, it is characterised in that including the first screw element, trip bolt and spacing ball, first spiral shell
The end face of line part has screwed hole, and the trip bolt screw thread is installed in the screwed hole, the radial direction of first screw element
With through hole, described through hole one end is connected with the screwed hole, and the other end and ft connection, the spacing ball are movably disposed in
The connectivity part of the through hole and the screwed hole, during make it that the trip bolt is tightened in the screwed hole, the fastening
The end of screw, which extrudes the spacing ball, makes it to movement on the outside of the through hole.
When anti-loose structure of the present utility model is threadedly coupled with one second screw element, can by the trip bolt and
Both spacing ball fastenings, concrete mode is：Second screw element is threadedly coupled with first screw element, then tightens institute
State trip bolt so that the spacing ball is displaced outwardly under the extruding of the trip bolt so as to be caught in the ditch of the second screw element
In groove, and then the first screw element stably links together with the second screw element, it is not easy to gets loose.
Further, the anti-loose structure includes multiple trip bolts and multiple spacing balls, and described first
Screw element has multiple screwed holes and multiple through holes corresponding with the screwed hole.
Further, the length of the through hole is less than the diameter of the spacing ball, to cause a part for the spacing ball
It is maintained in the screwed hole.
Further, the exit internal diameter of the through hole and ft connection is less than the external diameter of the spacing ball.
The two of the purpose of this utility model adopt the following technical scheme that realization：
A kind of checknut part, it is characterised in that its end face has screwed hole, and its radial direction has through hole, the through hole
One end connects with the screwed hole, the other end and ft connection of the through hole.
Further, the checknut part includes multiple screwed holes and multiple institutes corresponding with the screwed hole
State through hole.
Compared with prior art, the beneficial effects of the utility model are：Anti-loosing effect is good, and screw element is repeatable makes
With.
Brief description of the drawings
Fig. 1 is the sectional view of a preferred embodiment of threaded anti-loosing structure of the present utility model.
Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further, it is necessary to explanation is,
On the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in figure 1, anti-loose structure of the present utility model include the first screw element 1, the second screw element 2, trip bolt 3 with
And spacing ball 4.First screw element 1 and the second screw element 2 are threadedly coupled.
The end face of first screw element 1 has some screwed holes 10, and the screw thread of trip bolt 3 is installed in screwed hole 10, so as to
Trip bolt 3 is threadedly coupled with the first screw element 1.
The radial direction of first screw element 1 has several through holes 11, and one end of through hole 11 connects with screwed hole 10, through hole 11
The other end extends to the thread joint face of the first screw element 1.When the first screw element 1 is external thread structure, through hole 11 extends to
The lateral surface of first screw element 1, collects in the embodiment shown in Fig. 1, and the first screw element 1 is external thread structure；When the first screw thread
When part 1 is female thread structure, through hole 11 extends to the medial surface of the first screw element 1.
The gap of spacing ball 4 is cooperatively disposed to the connectivity part of through hole 11 and screwed hole 10, and the length of through hole 11 is less than spacing
The diameter of ball 4 a so that part for spacing ball 4 may remain in the screwed hole 10, so as to be threaded into when trip bolt 3
During hole 10, the end of trip bolt 3 produces extruding to spacing ball 4 so that spacing ball 4 is displaced outwardly, due to the first screw element 1 with
Second screw element 2 is threadedly coupled, and when spacing ball 4 is displaced outwardly, one part is caught in the groove of the second screw element 2, so as to
Formed and be engaged between the first screw element 1 and the second screw element 2, the first screw element 1 and the second screw element 2 will be released and must pull against
The resistance of trip bolt 3.
Further, the exit internal diameter of through hole 11 and ft connection is less than the external diameter of spacing ball 4, so as to avoid limiting
Position ball 4 drops from the through hole 11.
When needing to separate the first screw element 1 and the second screw element 2, it is necessary to first twist trip bolt 3 from screwed hole 10
Go out, now spacing ball 4 is no longer influenced by extruding, and when turning the first screw element 1 or the second screw element 2, spacing ball 4 is by outer masterpiece
With entering in through hole 11 and screwed hole 10, so as to which the first screw element 1 can be smoothly detached with the second screw element 2.
Further, the first screw element 1 is nut.Second screw element 2 is shaft core.
Above-mentioned embodiment is only preferred embodiment of the present utility model, it is impossible to is protected with this to limit the utility model
Scope, the change of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model scope claimed.
