Embodiment
The technical scheme in the embodiment of the utility model is clearly and completely retouched below in conjunction with attached drawing 1 to attached drawing 6
State, it is clear that described embodiment is only the part of the embodiment of the utility model, instead of all the embodiments.It is based on
Embodiment in the utility model, those of ordinary skill in the art are obtained all without creative efforts
Other embodiment, shall fall within the protection scope of the present invention.
If it is to be appreciated that related in the utility model embodiment directionality instruction (such as upper and lower, left and right, it is preceding,
Afterwards ...), then directionality instruction be only used for explain it is opposite between each component under a certain particular pose (as shown in drawings)
Position relationship, motion conditions etc., if the particular pose changes, directionality instruction also correspondingly changes correspondingly.
With reference to Fig. 1, a kind of shaft of automatic locking, including shaft body 1, has a locking on the shaft body 1
Mechanism 2, can be in close contact when the lockable mechanism 2 is moved to a lock part 11 on shaft body 1 with the lock part 11
And produce frictional force and realize that lockable mechanism 2 and lock part 11 lock.
In the present embodiment, when lockable mechanism 2 is moved to lock part 11, it can contact, connect with the lock part 11
In tactile process, frictional force increases, and the locking of shaft body 1 just can be realized when reaching a certain level.Due to being to use
CONTACT WITH FRICTION realizes locking, therefore can realize by the technical program the locking of the different angle of shaft body 1, i.e. shaft sheet
The angle that body 1 rotates is linear change, and locking is also linear change.
Specifically, with reference to Fig. 2, shaft body 1 includes lock part 11 and rotation section 12, and the minimum outer diameter of the lock part 11 is equal
More than the rotation section 12.And the shaft body 1 can be made using metal material.
Compares figure 3, the figure are the sectional view of lockable mechanism 2.The lockable mechanism 2 includes being socketed in 1 side of shaft body
Drag ring 21 and the jacket casing 22 for being socketed in the outside of drag ring 21, the portion of the drag ring 21 and the non-lock part 11 of shaft body 1
Dividing has gap, i.e. jacket casing 22 is not contacted with rotation section 12, and the jacket casing 22 is fixedly connected with drag ring 21, when drag ring 21 is slided
Move to the lock part 11 when the drag ring 21 and lock part 11 be fitted close and produce frictional force.Drag ring 21 has enough
Wearability, and its medial surface is rough surface, and the lateral surface of certain lock part 11 is also rough surface, so works as drag ring
21 and lock part 11 when be engaged, by increasing capacitance it is possible to increase frictional force, realizes more excellent latch functions.Certain jacket casing 22
It is stationarily connected to together with drag ring 21, connection can be realized by a transition zone between the two.The corresponding friction
The form fit of the inner shape of ring 21 and the lock part 11.Match somebody with somebody when the lock part 11 and drag ring 21 coordinate for interference
Close.
Detailed, the lockable mechanism 2 includes being socketed in the outside of shaft body 1 and keeps gap with the shaft body 1
Fixed seat 13, which is used to fix with external device, and the fixed seat 13 is socketed in one with 22 part of jacket casing
Rise, and the jacket casing 22 is merely able to move in the axial direction.The jacket casing 22 is produced by the fixed seat 13 circumferential
Constraint, when drag ring 21 and the cooperation of lock part 11, fixed seat 13 can prevent drag ring 21 from rotating, that is, realize
Locking.
Further, referring to Fig. 4, the fixed seat 13 has ring set 131, and the outer circumferential side of the ring set 131 has vertically
The strip 132 of setting, 22 medial surface of jacket casing have and the matched groove 221 of the strip 132.In this way, the ring set 131
It is fastened togather with jacket casing 22, and jacket casing 22 can be moved along 131 axial direction of ring set after engaging, but in circumferential direction
The upper cooperation by strip 132 and groove 221 is constrained.
Specifically, in the present embodiment, the lockable mechanism 2 connects an actuating unit 3, which can be certainly
It is dynamic to promote the lockable mechanism 2 to be moved to lock part 11.Lockable mechanism 2 is under the action of the promotion of actuating unit 3 to lock part 11
Mobile, when being moved into place, lockable mechanism 2 realizes locking with the lock part 11.
The actuating unit 3 can be diversified forms, and the detailed actuating unit 3 includes the support base with a straight slot 311
31, servomotor 32 is fixed in one end of the support base 31, and the output terminal of the servomotor 32 is fixedly connected with a screw 33, the silk
Thick stick 33 is located in the straight slot 311, and the screw 33 is threaded togather with sliding block 34；In the outside of support base 31 socket
One slide unit 35, the slide unit 35 are fixedly connected with the sliding block 34.Certainly, the servomotor 32 is acted on be subject to external controller
It can rotate, during rotation, screw 33 drives the sliding block 34 to slide, since sliding block 34 and slide unit 35 are to be connected to
Together, therefore slide unit 35 can also slide therewith in 34 sliding process of sliding block, and slide unit 35 is fixed with jacket casing 22, therefore jacket casing
22 and drag ring 21 can be to lock part 11 closer or far from realizing locking or unlock.Of course, in the present embodiment, due to bag
Ring set 131 and fixed seat 13 are included, therefore the slide unit 35 can be fixedly connected with realization certainly with the fixed seat or ring set 131
Dynamic locking or unlock.
In certain embodiments, the slide unit 35 is by the top plate 351 positioned at the top of support base 31 and positioned at 31 liang of support base
The right baffle-plate 352 and right shell body 353 of side, the top plate 351, the formation frame-type structure of left and right baffle 352,353, left and right baffle 352,
353 end is fixedly connected with the sliding block 34.It is to ensure that slide unit 35 slides steady using the purpose of the technical solution
It is qualitative, ensure promoting lockable mechanism 2 to stablize traveling.
In short, the locking of shaft is realized by the technical program, and lockable mechanism 2 is hardly damaged, and can realize
The linear locking of shaft rotational angle；At the same time when locking or unlock is needed, it is not necessary to manually locked.Certainly above
In the linear locking mentioned refer to lockable mechanism 2 shaft occur after any angle rotates can countershaft carry out locking.
According to the disclosure and teachings of the above specification, the utility model those skilled in the art can also be to above-mentioned reality
Apply mode make a change and modification.Therefore, the utility model is not limited to embodiment disclosed and described above, right
Some modifications and changes of the utility model should also be as falling into the scope of the claims of the utility model.In addition, to the greatest extent
Some specific terms have been used in pipe this specification, but these terms are merely for convenience of description, not to the utility model
Form any restrictions.
