Description

One word shaft

Technical field

The utility model relates to shaft technical fields, more particularly to an a kind of word shaft.

Background technique

Shaft is to realize the necessary constituent element of overturning or rotary components rotation, not only needs to meet the basic of access times Condition meets torsion, damping requirements are even more important, is reaching rotating range when especially rotating under special angle control The functions such as self-locking afterwards are indispensable.

Utility model content

A word shaft is provided the purpose of the utility model is to overcome shortcoming in the prior art.

To achieve the above object, the utility model adopts the following technical solutions:

One word shaft, including main structure body, the main structure body is including a long sleeve and is respectively arranged at the long sleeve The short sleeve and connecting shaft at both ends, the connecting shaft include attachment base and central axis, and the central axis is penetrated with the long sleeve Connection, is nested with torsional spring, spring, self-locking gasket and nut on the central axis respectively, and the self-locking gasket is by Cam gasket and recessed Take turns gasket composition.

Particularly, the connecting shaft is located by connecting with the long sleeve and fixed realize of short sleeve both ends encapsulation.

Particularly, it is equipped with isolation board inside the long sleeve, is equipped with location hole on the isolation board and the attachment base, The torsional spring both ends are fixed on the balance torsional adjusting that the positioning hole realizes left 90 degree and right 90 degree of rotations.

Particularly, the spring, which is set in the long sleeve, realizes that torsion, damping are adjusted.

Particularly, the concavo-convex position combination connection on the Cam gasket and concave wheel gasket realize rotate to 0 degree, it is 90 degree left And positioning when 90 degree right and self-locking.

Particularly, the central axis leading portion is equipped with screw thread, and the nut is set between the short sleeve and self-locking gasket, The nut is locked and is fixedly connected with the screw thread.

Particularly, the long sleeve is equipped with card slot, and the Cam gasket is equipped with tab, and the tab is set to described In card slot.

The utility model has the beneficial effects that: word shaft provided by the utility model, torsional spring provides torsion, realizes left The balance torsional of 90 degree and right 90 degree rotations is adjusted, and service life reaches 100,000 times or more, meets 0 degree, 90 degree of 90 degree of a left side and the right side When positioning and self-locking function, structure design is simple, and component collocation rationally, effectively realizes shaft position rotating function.

Specific embodiment

Below in conjunction with Figure of description, the utility model is described in further detail:

Embodiment 1:

As shown in Figs. 1-5, a word shaft disclosed in the present embodiment, including main structure body, the main structure body include one long Sleeve 3 and the short sleeve 8 and connecting shaft 1 for being respectively arranged at 3 both ends of long sleeve, the connecting shaft 1 include attachment base 12 and Central axis 13, the central axis 13 are penetrated with the long sleeve 3 and are connect, be nested with respectively on the central axis 13 torsional spring 2, spring 4, Self-locking gasket 5 and nut 7, the self-locking gasket 5 are made of Cam gasket 51 and concave wheel gasket 52.

The connecting shaft 1 is located by connecting with the long sleeve 3 and fixed realize of 8 both ends of short sleeve encapsulation.The long sleeve 3 Inside is equipped with isolation board 31, is equipped with location hole 41 on the isolation board 31 and the attachment base 12,2 both ends of torsional spring are fixed The balance torsional adjusting of left 90 degree and right 90 degree of rotations is realized in the location hole 41.The spring 4 is set to the long set Realize that torsion, damping are adjusted in cylinder 3.Rotation is realized in concavo-convex position combination connection on the Cam gasket 51 and concave wheel gasket 52 To 0 degree, left 90 degree and positioning when 90 degree of the right side and self-locking.13 leading portion of central axis is equipped with screw thread 14, and the nut 7 is set to Between the short sleeve 8 and self-locking gasket 5, the nut 7 is locked and is fixedly connected with the screw thread 14.On the long sleeve 3 Equipped with card slot 32, the Cam gasket 52 is equipped with tab 53, and the tab 53 is set in the card slot 32.

The present embodiment technical principle:

Torsion is provided by torsional spring, realizes that 90 degree of a left side and the balance torsional of right 90 degree of rotations are adjusted, service life reaches 10 Ten thousand times or more, meets 0 degree, left 90 degree and positioning and self-locking function when 90 degree of the right side, pass through spring realization torsion and damping, structure Design is simple, and component collocation rationally, effectively realizes shaft position rotating function, reasonable in design, shape-designing is simple and convenient.

The above is only the preferred embodiment to the utility model, is not defined to the scope of the utility model, Therefore under the premise of not departing from the spirit of the design of the utility model, this field ordinary engineering and technical personnel is to described in the utility model The equivalence changes or decoration that structure, feature and principle is made, should all fall into the protection scope of present utility model application patent.
