Description

A kind of shaft with lockable mechanism

Technical field

Shaft technical field is the utility model is related to, especially a kind of shaft with lockable mechanism.

Background technology

Shaft, is mainly used for being hinged for equipment.In the process used, when shaft stops, emergency case in order to prevent Generation, it is desirable to shaft cannot rotate, it is therefore desirable to which shaft is stuck to prevent from misrouting.In addition, it is sometimes necessary to which shaft is kept Certain rotational angle.Current some lockable mechanisms, such as the patented technology of Patent No. 201620467793.2 on the market, lead to Cross gear engagement and realize locking, easily collapse tooth, the in addition special angle fixation of shaft can not realize Linear Control.

Therefore, above-mentioned technical problem needs to solve.

Utility model content

For overcome the deficiencies in the prior art, the utility model proposes a kind of shaft with lockable mechanism, it is therefore intended that The probability of lockable mechanism damage is reduced, and realizes linear locking.

In order to solve above-mentioned technical problem, the utility model proposes basic technical scheme be；

A kind of shaft with lockable mechanism, including shaft body,

There is a lockable mechanism, when the lockable mechanism is moved to a lock part on shaft body on the shaft body It can be in close contact when dynamic with the lock part and produce frictional force and realize lockable mechanism and lock part locking.

Further, the lockable mechanism includes being socketed in the drag ring of shaft body side and is socketed in outside the drag ring The jacket casing of side, the part of the drag ring and the non-lock part of shaft body has gap, when drag ring slides into the lock part When the drag ring and lock part be fitted close and produce frictional force.

Further, the lockable mechanism includes being socketed in shaft outer body and keeps consolidating for gap with the shaft body Reservation, which is used to fix with external device, and the fixed seat connects together with 22 part of jacket casing, and should Jacket casing is merely able to move in the axial direction.

Further, the fixed seat has ring set, and the outer circumferential side of the ring set has axially disposed strip, the cylinder Covering medial surface has and the matched groove of the strip.

Further, the shape of the lock part is round table-like, and is tilted inwardly by outside.

The beneficial effects of the utility model are：

The technical solution of the utility model produces frictional force to realize the locking of shaft by lockable mechanism to lock part, should Lockable mechanism is hardly damaged during practicality, and the lock of the shaft can be realized when shaft rotates any angle Only fix.

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 4 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 with lockable mechanism, including shaft body 1, with one on the shaft body 1 Lockable mechanism 2, can be close with the lock part 11 when the lockable mechanism 2 is moved to a lock part 11 on shaft body 1 Contact 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.

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.Certainly the linear locking being mentioned above refers to lockable mechanism 2 and any angle occurs in shaft Can countershaft progress locking after rotation.

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.
