Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and reference
Accompanying drawing, further describes this utility model.But those skilled in the art know, this utility model is not limited to accompanying drawing
And following example.
The adjustment of displacement structure that the utility model proposes is as it is shown on figure 3, this adjustment of displacement structure can be used for band animal body linearly side
To moving back and forth, this straight line can be rectilinear direction at any angle, the axis direction of adjustment of displacement structure determine.Below with
Rectilinear direction is horizontal direction, and object is to illustrate as a example by camera lens.
This adjustment of displacement structure includes: transmission motor 1, device for disc 2, clutch disk 3, spring structure 4, positive stop 5
With 7 and slide construction 6.This transmission motor 1 is preferably electro-motor, it is also possible to be the output such as manual knob, hydraulic motor
The equipment of rotary power.
Device for disc 2 side (left side as shown in Figure 3) is connected with transmission motor 1, and device for disc 2 is at transmission motor 1
Rotate under drive.The opposite side (right side as shown in Figure 3) of device for disc 2 forms the first disc structure, this first circle
4 grooves it are evenly equipped with in the card of dish structure；Clutch disk 3 forms the second disc structure near the side of device for disc 2, should
The round boss of 4 and described matching grooves it is evenly equipped with in the card of the second disc structure.Those skilled in the art know, above-mentioned
The position of round boss or groove can exchange.Fig. 5 and Fig. 6 sets forth uniform groove and quantity on the first disc structure
It is 4, uniform round boss and example that quantity is 4 on the second disc structure, but those skilled in the art know groove
Or the quantity of boss and shape are not limited to this.In general, the quantity of groove or boss is the most, and engagement force is the biggest.Fig. 7
Giving the ball convex closure that boss is diameter 3mm, protrude plane 1mm, material is stainless example, but art technology
Personnel know the size of boss and material is not limited to this.
During work, when round boss accommodating in a groove time, device for disc 2 and clutch disk 3 in engagement, transmission motor
1 drives device for disc 2 to rotate together with clutch disk 3；When round boss completely disengages from from groove, transmission motor 1 is only
Driving device for disc 2 to rotate, clutch disk 3 stops the rotation, and now transmission motor 1 and device for disc 2 are in idling conditions.
Clutch disk 3 opposite side is connected with slide construction 6, by screw rod by the convert rotational motion of clutch disk 3 by screw rod
Becoming the horizontal movement of slide construction 6, slide construction 6 drives camera motion.Device for disc 2, clutch disk 3 and screw coaxial
Arrange.Second disc structure of clutch disk 3 be provided centrally with circular shaft hole, be connected with screw coaxial.This screw rod also can be with tooth
Wheel shafts etc. cooperatively form axial drive mechanism and realize above-mentioned transmission.Slide construction 6 is sliding shoe with threaded hole, by screw rod
External screw thread spin with screwed hole, thus drive slide construction 6 to slide.
Spring structure 4 and positive stop 5 are arranged between clutch disk 3 and slide construction 6, and wherein, spring structure 4 is sheathed
On screw rod, but not contacting with screw rod, its two ends are connected on clutch disk 3 and positive stop 5 respectively；During installation, spring
Structure 4 is in confined state or naturalness and ensures that round boss is accommodating in a groove.Positive stop 5 fixedly mounts in place
On the main body frame of the whole structure of transposition, screw rod is contactlessly through this positive stop 5.
Positive stop 7 is fixedly mounted on the main body frame of adjustment of displacement structure, positive stop 7 and positive stop 5 limit slippage
The distance that structure 6 moves horizontally.In order to improve the stability that screw rod rotates, it is spacing that screw rod also can contactlessly pass inside or through this
Block 7.
The running of this adjustment of displacement structure is: during normal operation, under the effect of spring structure 4, connects transmission motor 1
Device for disc 2 and connect the clutch disk 3 of screw rod in engagement, transmission motor 1 drives device for disc 2 and clutch disk
3 rotate, and then drive slide construction 6 level (left and right directions shown in Fig. 3) to slide by screw rod.
Needing slide construction 6 when left movement, transmission motor 1 rotates forward, when slide construction 6 moves at the positive stop 5 of left side
Time, it is impossible to move again, now clutch disk 3 meeting compression spring structure 4, separate with device for disc 2, as shown in Figure 4, circle
Dish device 2 and transmission motor 1 are in idling conditions；If now transmission motor 1 inverts, clutch disk 3 is compressed by spring structure 4
Resetting, device for disc 2 and clutch disk 3, again in engagement, drive slide construction 6 to move right by screw rod.
In like manner, when needing slide construction 6 to move right, transmission motor 1 inverts, when slide construction 6 moves to right side limiting block
Time at block 7, it is impossible to move again, now clutch disk 3 meeting compression spring structure 4, separate with device for disc 2, such as Fig. 4 institute
Showing, device for disc 2 and transmission motor 1 are in idling conditions；If now transmission motor 1 rotates forward, spring structure 4 is by clutch disk
3 compress reset, and device for disc 2 and clutch disk 3, again in engagement, drive slide construction 6 to move right by screw rod.
The rotating signal of above-mentioned transmission motor 1 can be rotated forward by mainboard, invert button control, if the sustained hold when extreme position
Mainboard button, then transmission motor 1 rotates always, and stop button then transmission motor 1 no longer rotates；Pin reversing button,
Then transmission motor 1 reversely rotates.
This utility model also proposed a kind of adjustment of displacement module, in order to realize camera lens upper and lower, move left and right, this adjustment of displacement
Module can include two above-mentioned adjustment of displacement structures, and as shown in Figure 8, the two adjustment of displacement structure provides above-below direction respectively
Transmission and the transmission of left and right directions, thus drive camera lens to move up and down and move left and right.The working method of two adjustment of displacement structures
Ditto, do not repeat them here.
It addition, those skilled in the art know, above-mentioned adjustment of displacement structure or module are not limited to use in the adjustment of displacement of camera lens, on
The quantity of the adjustment of displacement structure that rheme transposition mould preparation group includes is not limited to two.
Above, embodiment of the present utility model is illustrated.But, this utility model is not limited to above-mentioned embodiment.
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. done, should be included in this reality
Within novel protection domain.
