Description
Technical field
The present invention relates to field of connectors, especially relate to a kind of thread connection anti-loose spline structure.
Background technology
With the 18 century Britain industrial revolution, century had been crossed in machine-building already, became one of the most ripe industry, but vertical had
Germany manufactures such manufacture synonym, and machine-building is still constantly moving ahead, and keeps on improving the source improved especially.
Threaded is the modal connected mode of machinery industry, and locking thread naturally also becomes each designer and must examine
One of the key point considered, the most common locking thread has following several form: fastening screw nut, screw thread fastening glue, mark closely screw,
Spline reed etc..
According to different use environment, product structure size, the locking form of employing is also the most different, but various locking form
More or less have problems.As tradition spline reed, no problem on locking thread, but consider practical set time, at screw thread
It is linked and packed the most highly difficult.
Summary of the invention
It is an object of the invention on the basis of prior art, a kind of structure of design makes adapter use under vibration
Because of vibration, adapter will be come off, while protection adapter, additionally it is possible to solve the problem that adapter plugs together difficulty.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of thread connection anti-loose spline structure, including connecting overcoat, connecting inner sleeve and spline reed；
The inner surface of described connection overcoat one end provided circumferentially about has several mutually isostructural grooves, each groove same
There is the circular arc of three different radiis, remote along the radius of first circular arc of clockwise direction connecting sleeve thread engagement direction
Radius much larger than three-arc；
The same provided circumferentially about of described connection lining the outer surface of has several breach, arranges a spline spring in each breach
Sheet, each spline reed correspondence connects a groove of overcoat inner surface；
It is provided with protruding end in the middle of described spline reed, connects with being connected between inner sleeve breach employing tack coat；
Connect inner sleeve and retaining ring is set with being connected between overcoat, connect inner sleeve and mutually rotate with being connected between overcoat and will not take off
From.
In technique scheme, the different circular arc of three radiuses on each groove described is for arranging one continuously.
In technique scheme, described spline reed protruding end is smooth arc-shaped surface.
In technique scheme, in the groove of the protruding end Snap joint overcoat of described spline reed.
In technique scheme, the arc radius of described spline reed protruding end and groove the second arc radius phase
Join.
In technique scheme, described groove is evenly distributed on same circumference.
In technique scheme, described spline reed bonds with being connected between inner sleeve employing butter.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
Connector plug with socket to time slotting, owing to adapter sleeve groove the first arc radius is relatively big, chamfering relative smooth, be hampered
Power easily rotates, and makes screw thread be engaged screw-in clockwise easily；After plug screws, due to adapter sleeve groove three-arc radius relatively
Little, when product operates in vibration environment, the biggest by spline reed resistance, screw thread is screwing out difficulty, the just company of playing counterclockwise
Connect that device is locking and protective effect.Present configuration is simple, it is simple to processing and implementation, solves to connect while effectively protection adapter
Device plugs together difficult problem.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is to connect jacket structure schematic diagram,；
Fig. 2 is the structure enlarged diagram of groove；
Fig. 3 is spline reed structure schematic diagram；
Fig. 4 is connector construction schematic diagram；
Wherein: 1 is groove, 2 is spline reed.
Detailed description of the invention
All features disclosed in this specification, or disclosed all methods or during step, except mutually exclusive
Feature and/or step beyond, all can combine by any way.
As shown in Fig. 4, adapter of the present invention includes that one connects overcoat and a connection inner sleeve, connects inner sleeve
It is nested in connecting and inner sleeve is passed through the locking of locking mechanism so that connect inner sleeve and rotate each other with being connected overcoat, and even
Connect inner sleeve and be connected overcoat and will not mutually come off.
The present invention focuses on ingenious setting, and adapter sleeve groove has the circular arc of different radii, is come by circular arc size
Controlling drag size, make that adapter resistance when screwing is less is easily installed operation, adapter passes through spline under vibration
Reed is effectively protected adapter by resistance and is not fallen off greatly.As it is shown in figure 1, on the same circumference of inner surface connecting overcoat all
Even arranging several grooves, the effect of groove is for blocking spline reed, plays the effect of fixing connection.In the present invention in order to
Guarantee that the spline reed after connecting will not come off because of vibration, therefore in the design of groove, use design three continuously
Circular arc, the radius of each circular arc all differs.From connect overcoat screw thread nibble close direction clockwise from the beginning of, first
The radius R1 of circular arc to be far longer than the radius R2 of the 3rd circular arc, and the radius R of second circular arc is used to arrange spline reed
, as shown in Figure 2.
Spline reed is arranged on the outer surface connecting inner sleeve, if as it is shown on figure 3, arranging on the outer surface connecting inner sleeve
Dry breach, arranges a spline reed in each breach, the medium position of spline reed is outwardly, and protruding end is light
Slip circle face, the radius of smooth arc-shaped surface matches with the radius R of the second circular arc of groove.For ensureing spline reed and being connected inner sleeve
Connect, use and butter is set in breach, spline reed is attached on butter, by the viscosity of butter, spline reed is pasted
Live.
When being enclosed within connection outside connecting inner sleeve and being connected, because the corresponding groove of each spline reed, by rotating even
Connect overcoat and rotate around connecting inner sleeve so that spline reed snaps onto in groove.Because the radius of three circular arcs of groove is different, special
The radius of the first circular arc radius that is far longer than three-arc so that connect overcoat and connect inner sleeve be easy to screw into
Integrally.Being in after connecting in vibration environment, the three-arc radius of groove is little, and spline reed is by from three-arc
Resistance can be very big, so that spline reed will not rotate easily relative to the resistance of other two circular arcs.Further
Say because spline reed be connected between inner sleeve use butter bonding, the characteristic of butter make on spline reed produce
A vibration part can be absorbed by butter, thus play reduce vibration effect.
The simple in construction of the present invention, but effect is notable, makes adapter plug together easily, and can effectively prevent adapter
Shake under vibration comes off.
The invention is not limited in aforesaid detailed description of the invention.The present invention expands to any disclose in this manual
New feature or any new combination, and the arbitrary new method that discloses or the step of process or any new combination.
